It occurs in 1.5 to 2% of ectopic pregnancies. It can be asymptomatic for several years. However, various complications can occur that lead to diagnosis. The authors report a case of lithopedion complicated by acute intestinal obstruction in a 24-year-old woman in her first pregnancy. This complication occurred after 12 months of amenorrhoea. A mass containing a calcified foetus was removed by laparotomy.展开更多

Approximately 20% of patients with CRC will have distant metastasis at time of diagnosis, making them poor candidates for primary surgical resection. Similarly, 8%-25% of patients with CRC will present with bowel obstruction and will require palliative therapy. Emergent surgical decompression has a high mortality and morbidity, and often leads to a colostomy which impairs the patient’s quality of life. In the last decade, there has been an increasing use of colonic stents for palliative therapy to relieve malignant colonic obstruction. Colonic stents have been shown to be effective and safe to treat obstruction from CRC, and are now the therapy of choice in this scenario. In the setting of an acute bowel obstruction in patients with potentially resectable colon cancer, stents may be used to delay surgery and thus allow for decompression, adequate bowel preparation, and optimization of the patient’s condition for curative surgical intervention. An overall complication rate (major and minor) of up to 25% has been associated with the procedure. Long term failure of stents may result from stent migration and tumor ingrowth. In the majority of cases, repeat stenting or surgical intervention can successfully overcome these adverse effects.展开更多

METHODSA systematic search was performed to identify articles investigating the aetiology and pathophysiology of ACPO. A narrative synthesis of the evidence was undertaken. RESULTSNo consistent approach to the definition or reporting of ACPO has been developed, which has led to overlapping investigation with other conditions. A vast array of risk factors has been identified, supporting a multifactorial aetiology. The pathophysiological mechanisms remain unclear, but are likely related to altered autonomic regulation of colonic motility, in the setting of other predisposing factors. CONCLUSIONFuture research should aim to establish a clear and consistent definition of ACPO, and elucidate the pathophysiological mechanisms leading to altered colonic function. An improved understanding of the aetiology of ACPO may facilitate the development of targeted strategies for its prevention and treatment.展开更多

文摘BACKGROUND Internal hernia(IH)is a rare culprit of small bowel obstruction(SBO)with an incidence of<1%.It poses a considerable diagnostic challenge requiring a high index of suspicion to prevent misdiagnosis,improper treatment,and subsequent morbidity and mortality.AIM To determine the clinico-demographic profile,radiological and operative findings,and postoperative course of patients with IH and its association with SBO.METHODS Medical records of 586 patients with features of SBO presenting at a tertiary care centre at Lucknow,India between September 2010 and August 2023 were reviewed.RESULTS Out of 586 patients,7(1.2%)were diagnosed with IH.Among these,4 had congenital IH and 3 had acquired IH.The male-to-female ratio was 4:3.The median age at presentation was 32 years.Contrast-enhanced computed tomography(CECT)was the most reliable investigation for preoperative identification,demonstrating mesenteric whirling and clumped-up bowel loops.Left paraduodenal hernia and transmesenteric hernia occurred with an equal frequency(approximately 43%each).Intraoperatively,one patient was found to have bowel ischemia and one had associated malrotation of gut.During follow-up,no recurrences were reported.CONCLUSION IH,being a rare cause,must be considered as a differential diagnosis for SBO,especially in young patients in their 30s or with unexplained abdominal pain or discomfort post-surgery.A rapid imaging evaluation,preferably with CECT,is necessary to aid in an early diagnosis and prompt intervention,thereby reducing financial burden related to unnecessary investigations and preventing the morbidity and mortality associated with closed-loop obstruction and strangulation of the bowel.
文摘·AIM:To identify various risk factors that may play a significant role in the development of congenital nasolacrimal duct obstruction(CNLDO).·METHODS:This observational case-control study included a case group of 122 children less than two years of age with CNLDO who underwent probing and irrigation treatment at the ophthalmology department of Imam Khomeini Hospital in Ahvaz,Iran,from June 2022 to June2024.A control group of 122 age-matched children without CNLDO was also included for comparison.Data was collected from the children's medical records.·RESULTS:The study found a significant correlation between the occurrence of CNLDO and several maternal factors,such as preeclampsia,the use of levothyroxine,hypothyroidism,having more than three pregnancies(gravidity>3),natural pregnancy,and gestational diabetes mellitus.Additionally,in children,factors,such as oxygen therapy,anemia,reflux,jaundice,and a family history of CNLDO in first-degree relatives were associated with CNLDO,and maternal preeclampsia and hypothyroidism were found to significantly increase the risk of developing CNLDO in children.·CONCLUSION:Given that CNLDO affects both premature and full-term children,the present findings may potentially facilitate the early identification of children and infants at risk of nasolacrimal duct obstruction,thereby preventing the onset of chronic dacryocystitis.
文摘BACKGROUND Ileum adenocarcinoma(IA),a type of small bowel adenocarcinoma,is a rather uncommon factor associated with obstruction in small bowel.Owing to its location and indefinite clinical symptoms,the diagnosis of IA is difficult,and survival is usually poor.With respect to the rarity of this disease,very few studies have reported such cases to provide a reference for treatment.CASE SUMMARY In this manuscript,a case of a 48-year-old man presented with chronic right lower abdominal pain and distention,queasiness and emesis.A computed tomography scan revealed intestinal wall thickening and an intestinal obstruction in the terminal ileum.He was diagnosed with inflammatory bowel disease.However,his symptoms were not relieved after conservative treatment.The patient sub-sequently underwent exploratory laparotomy,and a tumour in the ileum measuring approximately 2.0 cm×2.0 cm that was located 20 cm from the ileocolic valve was discovered incidentally and was operatively resected along with the enlarged lymph nodes.Pathological examination revealed a stage IIA(T3N0M0)ulcerative IA.Along with imaging examinations,a diagnosis of primary IA with no lymph or distant metastases was considered.The patient was discharged and recovered well as of the writing of this manuscript.CONCLUSION IA should be considered as a differential diagnosis in cases of intestinal obstruction,and the recommended method for local disease treatment is surgery.

文摘BACKGROUND Among all forms of heterotopic ossification,heterotopic mesenteric ossification(HMO)is rare,with fewer than 100 reported cases to date.Postoperative early small bowel obstruction caused by HMO is even rarer,presenting extremely high surgical risks,the potential for multiple surgeries,and a poor prognosis.There have been no reported cases of conservative treatment for resolving such early postoperative obstruction.CASE SUMMARY A 57-year-old male presented with severe postoperative small bowel obstruction shortly after undergoing open radical resection for transverse colon cancer.Laparotomy revealed extensive adhesions in the proximal jejunum and mesen-tery,making it too difficult to relieve without injuring the small bowel.Addi-tionally,multiple fixed nodules were found in the mesentery during the opera-tion.Pathology confirmed the presence of heterotopic ossification.The patient was treated with methylprednisolone on postoperative day 1,which gradually relieved his symptoms.CONCLUSION Hormone therapy may have a potential role in treating small bowel obstruction caused by early HMO after operative intervention.
文摘Lithopedion is a rare clinical situation characterised by the calcification of a foetus that has died during an ectopic pregnancy, usually in the abdominal cavity. It occurs in 1.5 to 2% of ectopic pregnancies. It can be asymptomatic for several years. However, various complications can occur that lead to diagnosis. The authors report a case of lithopedion complicated by acute intestinal obstruction in a 24-year-old woman in her first pregnancy. This complication occurred after 12 months of amenorrhoea. A mass containing a calcified foetus was removed by laparotomy.

文摘[Objectives]To explore the effects of electroacupuncture combined with rehabilitation training on knee joint function,three-dimensional(3D)gait,and inflammatory markers in patients with knee osteoarthritis(KOA)of cold-dampness obstruction syndrome.[Methods]A total of 162 KOA patients admitted to Huadong Hospital Affiliated to Hehai University from January 2021 to May 2023 were enrolled and randomly divided into an electroacupuncture group and a control group,with 81 patients in each group.The control group received routine rehabilitation training,while the electroacupuncture group received electroacupuncture treatment in addition to the same rehabilitation training,both for 4 weeks.The efficacy,syndrome scores,Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC),Lysholm Knee Score(LKS),3D gait parameters,and levels of inflammatory markers were compared between the two groups.[Results]Following treatment,the total effective rate in the electroacupuncture group was 92.59%,which was significantly higher than 77.78%observed in the control group(P<0.05).Additionally,the electroacupuncture group exhibited lower TCM syndrome scores(P<0.05),reduced WOMAC scores,and elevated LKS scores compared to the control group(P<0.05).Gait parameters,including step frequency,step speed,stride length,initial ground contact flexion angle,maximum swing phase extension angle,and support phase extension angle,were all higher in the electroacupuncture group.Additionally,the sagittal plane maximum abduction moment was lower in the electroacupuncture group.Inflammatory markers showed that interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were lower in the electroacupuncture group,while transforming growth factor-β1(TGF-β1)was higher(P<0.05).[Conclusions]Electroacupuncture combined with rehabilitation training effectively enhances clinical efficacy,alleviates symptoms,improves knee joint mobility and walking ability,enhances knee function scores,and reduces inflammatory levels,contributing to the rapid recovery of knee joints in KOA patients.
文摘AIM:To reveal the research hotspots,trends,and future prospects of lacrimal duct obstruction disease(LDOD)from 1900 to 2024 through the bibliometric and visualized analysis,providing a directional guidance for research in this field.METHODS:The Web of Science Core Collection database was used to retrieve relevant literature.Data analysis and visualization were conducted using VOSviewer 1.6.20 and CiteSpace 6.3.1,including annual publication volume,trends,research areas,country/region and institution distribution,journal and co-cited journal analysis,author and co-cited author analysis,keyword and burst keyword analysis,etc.RESULTS:The study included a total of 1481 articles,revealing an overall upward trend in research on LDOD,with ophthalmology being the predominant field.While the United States previously led research efforts,India and China have emerged as key contributors since 2015.Mohammad Javed Ali stands out as the most influential author in this research area.Ophthalmic Plastic and Reconstructive Surgery has published the highest number of related articles,whereas Ophthalmology has the highest co-citation.The current focal points of research include minimally invasive and precise modifications to dacryocystorhinostomy,along with intubation,new materials for stents,and disease pathogenesis.CONCLUSION:LDOD research has garnered widely attention and exhibits a steady upward trend.Since 1900,the United States,China,and India have been the leading contributors to this field.Ophthalmologists continue to be the primary driving force behind LDOD research.The findings of this study suggest that at the forefront of LDOD research,our focus has long been on refining and innovating surgical treatment.The minimally invasive and precise modification of lacrimal surgery,represented by dacryocystorhinostomy,is the ongoing developmental direction of this field.Rapid interdisciplinary integration and in-depth exploration of pathogenesis and allergic inflammation will lead to the emergence of new materials,innovative technologies,and safer clinical treatment protocols.
文摘BACKGROUND Colon cancer is one of the most common malignancies of the digestive tract,often complicated by intestinal obstruction,which can significantly impact patient outcomes.While traditional laparotomy is the standard treatment,it is associated with large wounds,slower recovery,and higher complication rates.Laparoscopic surgery,a minimally invasive approach,may offer better outcomes for these patients.AIM To evaluate the clinical effects and prognosis of laparoscopic surgery in patients with colon cancer complicated by intestinal obstruction compared to traditional laparotomy.METHODS A retrospective analysis was conducted on 100 patients diagnosed with colon cancer and intestinal obstruction who underwent surgical treatment between January 2020 and December 2022.Patients were divided into two groups:The control group(CG),treated with traditional laparotomy,and the observation group(OG),treated with laparoscopic surgery.Clinical effects,surgical indicators,postoperative pain,inflammatory response,complication rates,quality of life,and prognosis were assessed and compared between the two groups.RESULTS The OG showed superior clinical outcomes compared to the CG(P<0.05).Patients in the OG had shorter operation times,reduced intraoperative blood loss,faster recovery of intestinal function,earlier mobilization,and shorter hospital stays(P<0.05).Postoperative pain(numerical rating scale scores)and inflam-matory markers[tumor necrosis factor-alpha(TNF-α),interleukin-6(IL-6),C-reactive protein(CRP)]were lower in the OG(P<0.05).The incidence of complic-ations was significantly reduced in the OG(6.00%vs 22.00%,P<0.05).Quality of life scores,including physical function,psychological state,social communication,and self-care ability,were significantly higher in the OG(P<0.05).There were no significant differences between groups in abdominal drainage volume,1-year tumor recurrence or metastasis rates,or 1-and 3-year survival rates(P>0.05).CONCLUSION The OG showed superior clinical outcomes compared to the CG(P<0.05).Patients in the OG had shorter operation times,reduced intraoperative blood loss,faster recovery of intestinal function,earlier mobilization,and shorter hospital stays(P<0.05).Postoperative pain(NRS scores)and inflammatory markers(TNF-α,IL-6,CRP)were lower in the OG(P<0.05).The incidence of complications was significantly reduced in the OG(6.00%vs 22.00%,P<0.05).Quality of life scores,including physical function,psychological state,social communication,and self-care ability,were significantly higher in the OG(P<0.05).There were no significant differences between groups in abdominal drainage volume,1-year tumor recurrence or metastasis rates,or 1-and 3-year survival rates(P>0.05).

文摘Objective:To observe the effect of Xipayimaizibizi oral liquid(XP)in an overactive bladder(OAB)experimental rat model and to explore its pharmacological mechanisms.Methods:Network pharmacology was used to explore the potential mechanisms of action of XP.The rats underwent bladder outlet obstruction surgery and were administered the corresponding drug concentrations by gavage for 4 weeks.The study observed the body weight,water intake,bladder and kidney indices(to evaluate their general status),urination behavior pattern(to observe frequency and urgency),and urodynamics(to measure bladder parameters).Hematoxylin and eosin and Masson's trichome staining were used to observe changes in the bladder structure.Enzyme-linked immunosorbent assay was used to measure the levels of nerve growth factor,brain-derived neurotrophic factor,and acetylcholine in the urine.The key targets involved in these mechanisms were validated using reverse transcription-quantitative polymerase chain reaction,immunohistochemistry,and western blot in vivo/vitro experiments.Result:Network pharmacological analysis predicted that XP may alleviate OAB by affecting the cholinergic synapse and calcium signaling pathways.XP treatment significantly reduced the bladder index,improved urine behavior and urodynamic parameters,decreased the neurotransmitters in urine,and reduced the thickness of the bladder wall and collagen ratio.These results indicate that XP can alleviate OAB symptoms and improve the bladder structure.In vivo/vitro experiments further demonstrated that XP can inhibit targets,such as muscarinic acetylcholine receptor 2,and participate in cholinergic synapses to further regulate the parasympathetic nervous system.It can also reduce the overexpression of Ca^(2+) caused by agonists,inhibit targets such as transient receptor potential vanilloid type 1,and participate in calcium signaling pathways to maintain Ca^(2+) homeostasis.Conclusion:These results suggest that XP inhibited bladder overactivity by maintaining Ca^(2+) homeostasis and regulating the parasympathetic nervous system.

文摘OBJECTIVE:To reach consensus on the diagnostic criteria of syndrome of dampness obstruction in idiopathic membranous nephropathy(IMN)patients by literature research and expert investigation(interviews and a Delphi method).METHODS:Our study was consistent with T/CACM 1336-2020.We searched the monographs and references published in the past 40 years(1983-2022),and established the diagnostic criteria pool of waterdampness syndrome and dampness-turbidity syndrome in Traditional Chinese Medicine(TCM)based on literature by using frequency statistics and correlation analysis.Expert investigation(interview method and two rounds of Delphi method)was used to form the diagnostic criteria of water-dampness syndrome and dampnessturbidity syndrome of idiopathic membranous nephropathy.Clinical diagnostic test research was carried out,and compared with“Diagnostic Criteria for dampness syndrome”(T/CACM 1454-2023)to evaluate the authenticity,reliability and clinical application value of the standard.RESULTS:A total of 122 relevant guides,standards,monographs and documents were included through searching books and Chinese databases.Four experts were interviewed and two rounds of delphi method(75 experts nationwide)were carried out.The experts'opinions are relatively concentrated and the differences are small.Based on the weight of each index,the diagnostic criteria indexes of water-dampness syndrome and dampness-turbidity syndrome were selected.After discussion by the core group members,the diagnostic model of"necessary symptoms and optional symptoms"was established,and the final diagnostic criteria of waterdampness syndrome and dampness-turbidity syndrome were established.One hundred and ninety-one inpatients and outpatients of Guangdong Provincial Hospital of Chinese Medicine from January 2021 to February 2023 were included in Diagnostic test study.There was no statistical difference in gender,age and course of disease(P>0.05).The sensitivity and specificity of the trial standard were 90.34%and 73.33%respectively,while the sensitivity and specificity of T/CACM 1454-2023 were 99.43%and 6.67%,respectively.CONCLUSIONS:The consensus-based diagnostic criteria for IMN can be widely incorporated in TCM.A further clinical study will be conducted to analyze the diagnosis value and cut-off score of our IMN criteria.
文摘BACKGROUND Mycobacterium tuberculosis(TB)is the causative agent of TB,a chronic granulo-matous illness.This disease is prevalent in low-income countries,posing a significant global health challenge.Gastrointestinal TB is one of the three forms.The disease can mimic other intra-abdominal conditions,leading to delayed diagnosis owing to the absence of specific symptoms.While gastric outlet obs-truction(GOO)remains a frequent complication,its incidence has declined with the advent of proton pump inhibitors and Helicobacter pylori eradication therapy.Gastroduodenal TB can cause upper gastrointestinal hemorrhage,obstruction,and malignancy-like tumors.CASE SUMMARY A 23-year-old male presented with recurrent epigastric pain,distension,nausea,vomiting,and weight loss,prompting a referral to a gastroenterologist clinic.Endoscopic examination revealed distorted gastric mucosa and signs of chronic inflammation.However,treatment was interrupted,possibly owing to vomiting or comorbidities such as human immunodeficiency virus infection or diabetes.Subsequent surgical intervention revealed a dilated stomach and diffuse thickening of the duodenal wall.Resection revealed gastric wall effacement with TB.CONCLUSION Primary gastric TB is rare,frequently leading to GOO.Given its rarity,suspicions should be promptly raised when encountering relevant symptoms,often requiring surgical intervention for diagnosis and treatment.

文摘BACKGROUND Endoscopic ultrasound-guided biliary drainage using electrocautery-enhanced(ECE)delivery of lumen-apposing metal stent(LAMS)is gradually being re-cognized as a viable palliative technique for malignant biliary obstruction after endoscopic retrograde cholangiopancreatography(ERCP)failure.However,most of the studies that have assessed its efficacy and safety were small and hetero-geneous.Prior meta-analyses of six or fewer studies that were published 2 years ago were therefore underpowered to yield convincing evidence.AIM To update the efficacy and safety of ECE-LAMS for treatment of biliary ob-struction after ERCP failure.METHODS We searched PubMed,EMBASE,and Scopus databases from the inception of the ECE technique to May 13,2022.Primary outcome measure was pooled technical success rate,and secondary outcomes were pooled rates of clinical success,re-intervention,and adverse events.Meta-analysis was performed using a random-effects model following Freeman-Tukey double-arcsine transformation in R soft-ware(version 4.1.3).RESULTS Fourteen eligible studies involving 620 participants were ultimately included.The pooled rate of technical success was 96.7%,and clinical success was 91.0%.Adverse events were reported in 17.5%of patients.Overall reinter-vention rate was 7.3%.Subgroup analyses showed results were generally consistent.CONCLUSION ECE-LAMS has favorable success with acceptable adverse events in relieving biliary obstruction when ERCP is impossible.The consistency of results across most subgroups suggested that this is a generalizable approach.

文摘Colorectal cancer (CRC) is the 3<sup>rd</sup> most common cancer in the United States with more than 10000 new cases diagnosed annually. Approximately 20% of patients with CRC will have distant metastasis at time of diagnosis, making them poor candidates for primary surgical resection. Similarly, 8%-25% of patients with CRC will present with bowel obstruction and will require palliative therapy. Emergent surgical decompression has a high mortality and morbidity, and often leads to a colostomy which impairs the patient’s quality of life. In the last decade, there has been an increasing use of colonic stents for palliative therapy to relieve malignant colonic obstruction. Colonic stents have been shown to be effective and safe to treat obstruction from CRC, and are now the therapy of choice in this scenario. In the setting of an acute bowel obstruction in patients with potentially resectable colon cancer, stents may be used to delay surgery and thus allow for decompression, adequate bowel preparation, and optimization of the patient’s condition for curative surgical intervention. An overall complication rate (major and minor) of up to 25% has been associated with the procedure. Long term failure of stents may result from stent migration and tumor ingrowth. In the majority of cases, repeat stenting or surgical intervention can successfully overcome these adverse effects.
文摘BACKGROUND Meckel’s diverticulum is a common congenital malformation of the small intestine,with the three most common complications being obstruction,per-foration,and inflammation.To date,only a few cases have been reported world-wide.In children,the clinical symptoms are similar to appendicitis.As most of the imaging features are nonspecific,the preoperative diagnosis is not precise.In addition,the clinical characteristics are highly similar to pediatric acute appendicitis,thus special attention is necessary to distinguish Meckel’s diver-ticulum from pediatric appendicitis.Patients with poor disease control should undergo laparoscopic exploration to avoid serious complications,including intestinal necrosis,intestinal perforation and gastrointestinal bleeding.CASE SUMMARY This report presents three cases of appendicitis in children combined with intestinal obstruction,which was caused by fibrous bands(ligaments)arising from the top part of Meckel's diverticulum,diverticular perforation,and diver-ticular inflammation.All three patients,aged 11-12 years,had acute appendicitis as their initial clinical presentation.All were treated by laparoscopic surgery with a favorable outcome.A complete dataset including clinical presentation,dia-gnostic imaging,surgical information,and histopathologic findings was also provided.CONCLUSION Preoperative diagnosis of Meckel’s diverticulum and its complications is challenging because its clinical signs and complications are similar to those of appendicitis in children.Laparoscopy combined with laparotomy is useful for diagnosis and treatment.
文摘Malignant gastric outlet obstruction(mGOO)is a major condition affecting patients with periampullary tumors,including pancreatic cancer.The current treatment options include surgical gastroenterostomy,endoscopic stenting and more recently EUS-guided gastroenterostomy.Most studies comparing the outcomes of the three procedures focus on technical success,clinical success and safety.Several“occult”outcomes relevant to the patient’s viewpoints and perspective may ultimately impact on cancer-related and overall survival,such as body mass composition,nutritional biomarkers,chemotherapy tolerance and patient-reported quality of life.The aim of this review is to provide an overview of potential key outcomes that should be explored in future comparative research around mGOO treatment options.

文摘BACKGROUND Abdominal cocoon syndrome(ACS)represents a category within sclerosing encapsulating peritonitis,characterized by the encapsulation of internal organs with a fibrous,cocoon-like membrane of unknown origin,resulting in bowel obstruction and ischemia.Diagnosing this condition before surgery poses a cha-llenge,often requiring confirmation during laparotomy.In this context,we depict three instances of ACS:One linked to intestinal obstruction,the second exclu-sively manifesting as intestinal ischemia without any obstruction,and the final case involving a discrepancy between the radiologist and the surgeon.CASE SUMMARY Three male patients,aged 53,58,and 61 originating from Northern Thailand,arrived at our medical facility complaining of abdominal pain without any prior surgeries.Their vital signs remained stable during the assessment.The diagnosis of abdominal cocoon was confirmed through abdominal computed tomography(CT)before surgery.In the first case,the CT scan revealed capsules around the small bowel loops,showing no enhancement,along with mesenteric congestion affecting both small and large bowel loops,without a clear obstruction.The second case showed intestinal obstruction due to an encapsulated capsule on the CT scan.In the final case,a patient presented with recurring abdominal pain.Initially,the radiologist suspected enteritis as the cause after the CT scan.However,a detailed review led the surgeon to suspect encapsulating peritoneal sclerosis(ACS)and subsequently perform surgery.The surgical procedure involved complete removal of the encapsulating structure,resection of a portion of the small bowel,and end-to-end anastomosis.No complications occurred during surgery,and the patients had a smooth recovery after surgery,eventually discharged in good health.The histopathological examination of the fibrous membrane(cocoon)across all cases consistently revealed the presence of fibro-collagenous tissue,without any indications of malignancy.CONCLUSION Individuals diagnosed with abdominal cocoons commonly manifest vague symptoms of abdominal discomfort.An elevated degree of clinical suspicion,combined with the application of appropriate radiological evaluations,markedly improves the probability of identifying the abdominal cocoon before surgical intervention.In cases of complete bowel obstruction or ischemia,the established norm is the comprehensive removal of the peritoneal sac as part of standard care.Resection with intestinal anastomosis is advised solely when ischemia and gangrene have been confirmed.
文摘To critically review the literature addressing the definition, epidemiology, aetiology and pathophysiology of acute colonic pseudo-obstruction (ACPO). METHODSA systematic search was performed to identify articles investigating the aetiology and pathophysiology of ACPO. A narrative synthesis of the evidence was undertaken. RESULTSNo consistent approach to the definition or reporting of ACPO has been developed, which has led to overlapping investigation with other conditions. A vast array of risk factors has been identified, supporting a multifactorial aetiology. The pathophysiological mechanisms remain unclear, but are likely related to altered autonomic regulation of colonic motility, in the setting of other predisposing factors. CONCLUSIONFuture research should aim to establish a clear and consistent definition of ACPO, and elucidate the pathophysiological mechanisms leading to altered colonic function. An improved understanding of the aetiology of ACPO may facilitate the development of targeted strategies for its prevention and treatment.
文摘Objective:To scrutinize the definitions of minimal invasive surgical therapy(MIST)and to investigate urologists’knowledge,attitudes,and practices for benign prostatic obstruction surgeries.Methods:A 36-item survey was developed with a Delphi method.Questions on definitions of MIST and attitudes and practices of benign prostatic obstruction surgeries were included.Urologists were invited globally to complete the online survey.Consensus was achieved when more than or equal to 70%responses were“agree or strongly agree”and less than or equal to 15%responses were“disagree or strongly disagree”(consensus agree),or when more than or equal to 70%responses were“disagree or strongly disagree”and less than or equal to 15%responses were“agree or strongly agree”(consensus disagree).Results:The top three qualities for defining MIST were minimal blood loss(n=466,80.3%),fast post-operative recovery(n=431,74.3%),and short hospital stay(n=425,73.3%).The top three surgeries that were regarded as MIST were Urolift®(n=361,62.2%),Rezum®(n=351,60.5%),and endoscopic enucleation of the prostate(EEP)(n=332,57.2%).Consensus in the knowledge section was achieved for the superiority of Urolift®,Rezum®,and iTIND®over transurethral resection of the prostate with regard to blood loss,recovery,day surgery feasibility,and post-operative continence.Consensus in the attitudes section was achieved for the superiority of Urolift®,Rezum®,and iTIND®over transurethral resection of the prostate with regard to blood loss,recovery,and day surgery feasibility.Consensus on both sections was achieved for EEP as the option with the better symptoms and flow improvement,lower retreatment rate,and better suitable for prostate more than 80 mL.Conclusion:Minimal blood loss,fast post-operative recovery,and short hospital stay were the most important qualities for defining MIST.Urolift®,Rezum®,and EEP were regarded as MIST by most urologists.
文摘AIM:To compare surgical outcomes between the conventional endoscopic dacryocystorhinostomy(DCR)and a modified endoscopic DCR for the treatment of nasolacrimal duct obstruction(NLDO),and evaluate factors associated with the surgical success rate.METHODS:Medical records of patients who underwent primary DCR surgery between January 2016 and July 2020 at the Otorhinolaryngology Department of Eye and Ear International Hospital,Lebanon were reviewed.RESULTS:The study group consisted of 50 consecutive modified endoscopic DCR and the control group consisted of 138 consecutive conventional endoscopic DCR.The success rates at 1y were 98.0%(49 out of 50)for modified DCR,significantly higher compared to 84.8%(117/138)for the conventional DCR;there was no significant difference in the success rate throughout the years in terms of both surgical techniques.The modified surgery vs traditional[adjusted odds ratio(aOR)=14.96]and having an adjunctive septoplasty surgery vs not(aOR=3.99)were significantly associated with higher odds of success.CONCLUSION:Mucosal flap preservation and apposition shows significant improvement in the surgical success rate.Moreover,there is no statistically significant difference found in terms of complication rate and mean operative time between the conventional and the modified techniques.
