METHODS We systematically reviewed 331 consecutive patients who underwent laparoscopic anterior resection for rectal cancer and prophylactic ileostomy in our institution from June 2010 to October 2016, including 155 patients who underwent specimen extraction via a prophylactic ileostomy procedure(experimental group), and 176 patients who underwent specimen extraction via a small lower abdominal incision(control group). Clinical data were collected from both groups andstatistically analyzed. RESULTS The two groups were matched in clinical characteristics and pathological outcomes. However, mean operative time was significantly shorter in the experimental group compared to the control group(161.3 ± 21.5 min vs 168.8 ± 20.5 min; P = 0.001). Mean estimated blood loss was significantly less in the experimental group(77.4 ± 30.7 mL vs 85.9 ± 35.5 mL; P = 0.020). The pain reported by patients during the first two days after surgery was significantly less in the experimental group than in the control group. No wound infections occurred in the experimental group, but 4.0% of the controls developed wound infections(P = 0.016). The estimated 5-year disease-free survival and overall survival rate were similar between the two groups.CONCLUSION Surgical specimen extraction via a prophylactic ileostomy procedure represents a secure and feasible approach to laparoscopic rectal cancer surgery, and embodies the principle of minimally invasive surgery.展开更多

AIM To determine potential predictors of high output related complications in patients with diverting loop ileostomy creation after colorectal surgery. METHODS Patients who underwent open and laparoscopic colorectal surgery requiring a diverting loop ileostomy from January 2010 to March 2018 were retrospectively analyzed. We included patients older than 18 years, who underwent colorectal surgery with primary low pelvic anastomosis, and with the creation of a diverting loop ileostomy, at elective or emergency settings for the treatment of benign or malignant conditions. Univariate and multivariate logistic regression analysis was used to determine the effect of the potential predictors on the rate of high output related complications. The high output related complications were dehydration and acute renal failure that required visits to the emergency department and hospitalizations. RESULTS Of the 102 patients included in the study, 23.5%(n = 24) suffered high output related complications. In this group of patients at least one visit to the emergency department (mean 1.6), and at least one readmission to the hospital was needed. The factors associated with high-output ileostomy, in the univariate analysis, were: urgent surgical intervention (OR = 2.6;P = 0.047), the development of postoperative complications (OR = 3;P = 0.024), have ulcerative colitis (OR = 4.8;P = 0.017), use of steroids (OR = 4.3;P = 0.010), mean output at discharge greater than 1000 mL/24 h (OR = 3.2;P = 0.016), and use of loperamide at discharge (OR = 2.8;P = 0.032). Multivariate logistic regression analysis identified two independent risk factors for high output related complications: ulcerative colitis [OR = 7.6 (95%CI: 1.81-31.95);P = 0.006], and ileostomy output at discharge ≥ 1000 mL/24 h [OR = 3.3 (1.18-9.37);P = 0.023]. CONCLUSION In our study, patients with ulcerative colitis and those with an ileostomy output above 1000 mL/24 h at discharge, were at increased risk of high output related complications.展开更多

METHODS: A retrospective analysis of 93 patients, who had undergone elective ileostomy closure between 2009 and 2013 was performed. Demographic, clinical and surgical variables were reviewed for analysis. All complications were recorded, and classified according to the Clavien-Dindo Classification. Statistical univariate and multivariate analysis was performed, setting a P value of 0.05 for significance.RESULTS: The patients had a mean age of 60.3 years, 58% male. The main procedure for ileostomy cre-ation was rectal cancer(56%), and 37% had received preoperative chemo-radiotherapy. The average delay from creation to closure of the ileostomy was 10.3 mo. Postoperative complications occurred in 40% of the pa-tients, with 1% mortality. The most frequent were ileus(13%) and wound infection(13%). Pseudomembra-nous colitis appeared in 4%. Increased postoperative complications were associated with delay in ileostomyclosure(P = 0.041). Male patients had more complica-tions(P = 0.042), mainly wound infections(P = 0.007). Pseudomembranous colitis was also associated with the delay in ileostomy closure(P = 0.003). End-to-end in-testinal anastomosis without resection was significantly associated with postoperative ileus(P = 0.037). CONCLUSION: Although closure of a protective il-eostomy is a fairly common surgical procedure, it has a high rate of complications, and this must be taken into account when the indication is made. The delay in stoma closure can increase the rate of complications in general, and specifically wound infections and colitis.展开更多

METHODS: Five patients underwent enterectomy and partially anastomosed end-loop ileostomy at the University Hospital of Larissa between 2000 and 2006. Enterectomy was performed because of conditions such as mesenteric vascular occlusive disease, radiation entritis and small bowel injury. RESULTS: Postoperatively, none of the patients developed any stoma-related or anastomotic complications. There were no major complications. All patients were discharged between the 8th and 15th day after the procedure, and the stoma was closed 3 wk to 4 wk later. CONCLUSION: We believe that our proposed modification of end-loop ileostomy is a simple, quick and safe technique with minimal stoma-related morbidity, and with simple and safe reversion. This technique can be considered as a useful option in the treatment of ischemic or radiation-induced enteritis, and in the management of severe intestinal trauma.展开更多

A rare and late complication of this treatment is carcinoma arising at the ileostomy site. We describe two such cases: a 78-year-old male 30 years after subtotal colectomy and ileostomy for FAP, and an 85-year-old male 50 years after colectomy and ileostomy for ulcerative colitis. The long latency period between creation of the ileostomies and development of carcinoma suggests a chronic metaplasia due to an irritating/inflammatory causative factor. Surgical excision of the mass and relocation of the stoma is the mainstay of therapy, with possible benefits from adjuvant chemotherapy. Newly developed lesions at stoma sites should be biopsied to rule out the possibility of this rare ileostomy complication.展开更多

A double-channeled therapeutic endoscope was introduced perorally into the stomach. A gastrostomy was made using a 2-cmtransversal mucosal incision following the creation of a 5-cm longitudinal pelvis-directed submucosal tunnel. The pneumoperitoneum was established via the endoscope. In the initial three operations of the series, a laparoscope was transumbilically inserted for guiding the tunnel direction, intraperitoneal spatial orientation and distal ileum identification. Endoscopic tube ileostomy was conducted by adopting an introducer method and using a Percutaneous Endoscopic Gastrostomy Catheter Kit equipped with the Loop Fixture. The distal tip of the 15 Fr catheter was placed toward the proximal limb of the ileum to optimize intestinal content drainage. Finally, the tunnel entrance of the gastrostomy was closed using nylon endoloops with the aid of a twin grasper. The gross and histopathological integrity of gastrostomy closure and the abdominal wall-ileum stoma tract formation were assessed 1 wk after the operation.RESULTS Transgastric endoscopic tube ileostomy was successful in all six pigs, without major bleeding. The mean operating time was 71 min(range: 60-110 min). There were no intraoperative complications or hemodynamic instability. The post-mortem, which was conducted 1-wk postoperatively, showed complete healing of the gastrostomy and adequate stoma tract formation of ileostomy.CONCLUSION Transgastric endoscopic tube ileostomy is technically feasible and reproducible in an animal model, and this technique is worthy of further improvement.展开更多

The aim of this retrospective comparative study was to assess three different techniques of loop support. Methods: The study included 65 pa- tients who had loop ileostomy or colostomy formed. Depending on the decision of the operating surgeon, one of three techniques was chosen to fixate the stoma loop: an epicutaneous plastic rod (group 1, n = 14), an epicutaneous suture-fixated silicone drain (group 2, n = 27), or a subcutaneous silicone drain (group 3, n = 24). Results: The majority of patients (85%) received loop ileostomy. Pain intensity was significantly (p = 0.0014) different among the three groups. A total of 19 patients (30%) suffered a complication. There was a tendency towards less complications if the stoma was secured by a silicone drain with epicutaneous fixation. Comfort with stoma care was significantly different, with group 3 experiencing the best results. Conclusions: Using a subcutaneously tunnelled silicon drain as a stoma bridge results in less complications, less pain and higher satisfaction as compared to the conventional plastic rod. Conventional plastic rods should be avoided.展开更多

Methods: The PubMed, EMBASE, Cochrane Library databases and two randomized controlled trials registration centers were thoroughly searched until April 2017. The clinical outcomes of IVF/ICSI cycles were compared between two groups with double-lumen needle and single-lumen needle. Results: Four RCT studies were included in this present meta-analysis. The oocytes yield was similar in two groups (OR 0.88, 95%CI 0.66 - 1.16;I2 = 4%). The procedure time with double-lumen needle was significantly longer than that with single-lumen needle (IV = 1.98, 95%CI 0.95 - 3.00;I2 = 86%). The fertilization rate with double-lumen needle was lower than that with single-lumen needle (OR 0.66, 95%CI 0.44 - 0.97;I2 = 0%). There was no significant difference of live birth rate in two groups (OR 0.76, 95%CI 0.32 - 1.76;I2 = 41%). Conclusion: Double-lumen needle could not benefit patients with a POR in terms of the number of oocytes retrieved, oocyte recovery rate, normal fertilization rate, clinical pregnancy rate, and live birth rate, compared with single-lumen needle.展开更多

文摘BACKGROUND Despite the potential benefits of fecal diversion after low pelvic anastomosis in colorectal surgery, diverting loop ileostomy construction is related to significant rates of complications. AIM To determine potential predictors of high output related complications in patients with diverting loop ileostomy creation after colorectal surgery. METHODS Patients who underwent open and laparoscopic colorectal surgery requiring a diverting loop ileostomy from January 2010 to March 2018 were retrospectively analyzed. We included patients older than 18 years, who underwent colorectal surgery with primary low pelvic anastomosis, and with the creation of a diverting loop ileostomy, at elective or emergency settings for the treatment of benign or malignant conditions.

In this group of patients at least one visit to the emergency department (mean 1.6), and at least one readmission to the hospital was needed. The factors associated with high-output ileostomy, in the univariate analysis, were: urgent surgical intervention (OR = 2.6;P = 0.047), the development of postoperative complications (OR = 3;P = 0.024), have ulcerative colitis (OR = 4.8;P = 0.017), use of steroids (OR = 4.3;P = 0.010), mean output at discharge greater than 1000 mL/24 h (OR = 3.2;P = 0.016), and use of loperamide at discharge (OR = 2.8;P = 0.032). Multivariate logistic regression analysis identified two independent risk factors for high output related complications: ulcerative colitis [OR = 7.6 (95%CI: 1.81-31.95);P = 0.006], and ileostomy output at discharge ≥ 1000 mL/24 h [OR = 3.3 (1.18-9.37);P = 0.023]. CONCLUSION In our study, patients with ulcerative colitis and those with an ileostomy output above 1000 mL/24 h at discharge, were at increased risk of high output related complications.
文摘AIM: To study the morbidity and complications as-sociated to ileostomy reversal in colorectal surgery pa-tients, and if these are related to the time of closure. METHODS: A retrospective analysis of 93 patients, who had undergone elective ileostomy closure between 2009 and 2013 was performed. Demographic, clinical and surgical variables were reviewed for analysis. All complications were recorded, and classified according to the Clavien-Dindo Classification. Statistical univariate and multivariate analysis was performed, setting a P value of 0.05 for significance.RESULTS: The patients had a mean age of 60.3 years, 58% male. The main procedure for ileostomy cre-ation was rectal cancer(56%), and 37% had received preoperative chemo-radiotherapy. The average delay from creation to closure of the ileostomy was 10.3 mo. Postoperative complications occurred in 40% of the pa-tients, with 1% mortality. The most frequent were ileus(13%) and wound infection(13%). Pseudomembra-nous colitis appeared in 4%. Increased postoperative complications were associated with delay in ileostomyclosure(P = 0.041). Male patients had more complica-tions(P = 0.042), mainly wound infections(P = 0.007). Pseudomembranous colitis was also associated with the delay in ileostomy closure(P = 0.003). End-to-end in-testinal anastomosis without resection was significantly associated with postoperative ileus(P = 0.037). CONCLUSION: Although closure of a protective il-eostomy is a fairly common surgical procedure, it has a high rate of complications, and this must be taken into account when the indication is made. The delay in stoma closure can increase the rate of complications in general, and specifically wound infections and colitis.

文摘Continent ileostomy can be defined as a surgical procedure that facilitates planned intermittent evacuation of a bowel reservoir through an ileostomy.It was devised by Nils Kock in 1969.Subsequently,continent ileostomy (or Kock pouch) became a viable alternative in the management of patients who had traditionally required an end ileostomy.Kock pouch appeared to provide substantial physical and psychosocial benefits over a conventional ileostomy.The procedure became popular until ileal pouch anal anastomosis (IPAA) was introduced in 1980.Despite its benefits,continent ileostomy had many short term complications including intubation problems,ileus,anastomotic leaks,peritonitis and valve problems.Operative mortalities have also been reported in the literature.Most of these problems have been eliminated with increasing experience;however,valverelated problems remain as an "Achilles' heel" of the technique.Many modifications have been introduced to prevent this problem.Some patients have had their pouch removed because of complications mainly related to valve dysfunction.Although revision rates can be high,most of the patients who retain their reservoirs are satisfied with regard to their health status and quality of life.Today,this procedure is still appropriate for selected patients for whom pouch surgery is not possible or for patients who have failed IPAA.Both the patient and their physician must be highly motivated to accept the risk of failure and the subsequent need for revisional operations.

文摘BACKGROUND Although minimally invasive surgery is becoming more commonly applied for ileostomy reversal(IR),there have been relatively few studies of IR for patients with Crohn's disease(CD).It is therefore important to evaluate the potential benefits and risks of laparoscopy for patients with CD.AIM To compare the safety,feasibility,and short-term and long-term outcomes of laparoscopic IR(LIR)vs open IR(OIR)for the treatment of CD.METHODS The baseline characteristics,operative data,and short-term(30-d)and long-term outcomes of patients with CD who underwent LIR and OIR at our institution between January 2017 and January 2020 were retrieved from an electronic database and retrospectively reviewed.RESULTS Of the 60 patients enrolled in this study,LIR was performed for 48 and OIR for 12.There were no statistically significant differences in baseline characteristics,operation time,intraoperative blood loss,days to flatus and soft diet,postoperative complications,hospitalization time,readmission rate within 30 d,length of hospitalization,hospitalization costs,or reoperation rate after IR between the two groups.However,patients in the LIR group more frequently required lysis of adhesions as compared to those in the OIR group(87.5%vs 41.7%,respectively,P<0.05).Notably,following exclusion of patients who underwent enterectomy plus IR,OIR was more advantageous in terms of postoperative recovery of gastrointestinal function and hospitalization costs.CONCLUSION The safety and feasibility of LIR for the treatment of CD are comparable to those of OIR with no increase in intraoperative or postoperative complications.
文摘AIM: To evaluate a new technique of temporary ileal anastomotic stoma, following small bowel resection, in patients where the anastomosis is anticipated to have borderline margins with dubious viability. METHODS: Five patients underwent enterectomy and partially anastomosed end-loop ileostomy at the University Hospital of Larissa between 2000 and 2006. Enterectomy was performed because of conditions such as mesenteric vascular occlusive disease, radiation entritis and small bowel injury. RESULTS: Postoperatively, none of the patients developed any stoma-related or anastomotic complications. There were no major complications. All patients were discharged between the 8th and 15th day after the procedure, and the stoma was closed 3 wk to 4 wk later. CONCLUSION: We believe that our proposed modification of end-loop ileostomy is a simple, quick and safe technique with minimal stoma-related morbidity, and with simple and safe reversion. This technique can be considered as a useful option in the treatment of ischemic or radiation-induced enteritis, and in the management of severe intestinal trauma.
文摘Total colectomy with ileostomy placement is a treatment for patients with inflammatory bowel disease or familial adenomatous polyposis(FAP). A rare and late complication of this treatment is carcinoma arising at the ileostomy site. We describe two such cases: a 78-year-old male 30 years after subtotal colectomy and ileostomy for FAP, and an 85-year-old male 50 years after colectomy and ileostomy for ulcerative colitis. The long latency period between creation of the ileostomies and development of carcinoma suggests a chronic metaplasia due to an irritating/inflammatory causative factor. Surgical excision of the mass and relocation of the stoma is the mainstay of therapy, with possible benefits from adjuvant chemotherapy. Newly developed lesions at stoma sites should be biopsied to rule out the possibility of this rare ileostomy complication.

文摘AIM To introduce natural orifice transgastric endoscopic surgery(NOTES) tube ileostomy using pelvis-directed submucosal tunneling endoscopic gastrostomy and endoscopic tube ileostomy.METHODS Six live pigs(three each in the non-survival and survival groups) were used. A double-channeled therapeutic endoscope was introduced perorally into the stomach. A gastrostomy was made using a 2-cmtransversal mucosal incision following the creation of a 5-cm longitudinal pelvis-directed submucosal tunnel. The pneumoperitoneum was established via the endoscope. In the initial three operations of the series, a laparoscope was transumbilically inserted for guiding the tunnel direction, intraperitoneal spatial orientation and distal ileum identification. Endoscopic tube ileostomy was conducted by adopting an introducer method and using a Percutaneous Endoscopic Gastrostomy Catheter Kit equipped with the Loop Fixture. The distal tip of the 15 Fr catheter was placed toward the proximal limb of the ileum to optimize intestinal content drainage. Finally, the tunnel entrance of the gastrostomy was closed using nylon endoloops with the aid of a twin grasper. The gross and histopathological integrity of gastrostomy closure and the abdominal wall-ileum stoma tract formation were assessed 1 wk after the operation.RESULTS Transgastric endoscopic tube ileostomy was successful in all six pigs, without major bleeding. The mean operating time was 71 min(range: 60-110 min). There were no intraoperative complications or hemodynamic instability. The post-mortem, which was conducted 1-wk postoperatively, showed complete healing of the gastrostomy and adequate stoma tract formation of ileostomy.CONCLUSION Transgastric endoscopic tube ileostomy is technically feasible and reproducible in an animal model, and this technique is worthy of further improvement.
文摘Purpose: Beside the conventional plastic rods, different techniques and materials have been proposed in the last years to prevent the loop from retraction into the abdominal cavity. The aim of this retrospective comparative study was to assess three different techniques of loop support. Methods: The study included 65 pa- tients who had loop ileostomy or colostomy formed. Depending on the decision of the operating surgeon, one of three techniques was chosen to fixate the stoma loop: an epicutaneous plastic rod (group 1, n = 14), an epicutaneous suture-fixated silicone drain (group 2, n = 27), or a subcutaneous silicone drain (group 3, n = 24). Results: The majority of patients (85%) received loop ileostomy. Pain intensity was significantly (p = 0.0014) different among the three groups. A total of 19 patients (30%) suffered a complication. There was a tendency towards less complications if the stoma was secured by a silicone drain with epicutaneous fixation. Comfort with stoma care was significantly different, with group 3 experiencing the best results. Conclusions: Using a subcutaneously tunnelled silicon drain as a stoma bridge results in less complications, less pain and higher satisfaction as compared to the conventional plastic rod. Conventional plastic rods should be avoided.
文摘Restorative proctocolectomy(RP) is the treatment of choice in patients affected with refractory ulcerative colitis or familial adenomatous polyposis.Surgery in elective settings is often performed in 2 stages,fashioning an ileostomy which is closed 2-3-mo later.It is still debated whether omitting ileostomy could offer advantages in the management of patients undergoing RP.
文摘Background: The present study performed a meta-analysis to comprehensively analyze existing randomized controlled trials (RCT) involving the use of double-lumen needle in patients with poor ovarian response to explore whether double-lumen needle was good for specific patients. Methods: The PubMed, EMBASE, Cochrane Library databases and two randomized controlled trials registration centers were thoroughly searched until April 2017. The clinical outcomes of IVF/ICSI cycles were compared between two groups with double-lumen needle and single-lumen needle. Results: Four RCT studies were included in this present meta-analysis. The oocytes yield was similar in two groups (OR 0.88, 95%CI 0.66 - 1.16;I2 = 4%). The procedure time with double-lumen needle was significantly longer than that with single-lumen needle (IV = 1.98, 95%CI 0.95 - 3.00;I2 = 86%). The fertilization rate with double-lumen needle was lower than that with single-lumen needle (OR 0.66, 95%CI 0.44 - 0.97;I2 = 0%). There was no significant difference of live birth rate in two groups (OR 0.76, 95%CI 0.32 - 1.76;I2 = 41%). Conclusion: Double-lumen needle could not benefit patients with a POR in terms of the number of oocytes retrieved, oocyte recovery rate, normal fertilization rate, clinical pregnancy rate, and live birth rate, compared with single-lumen needle.
文摘BACKGROUND Ileostomies are commonly performed after colon and rectal surgeries.Laparoscopy-assisted ileostomy with adhesion lysis may have potential benefits over conventional open surgery.AIM To compare the outcomes of laparoscopy-assisted and conventional ileostomies.METHODS Data from 48 consecutive patients who underwent ileostomy at our institution between May 2021 and May 2022 were retrospectively analyzed.The groups comprised 26 and 22 patients who underwent laparoscopic ileostomy(laparoscopic group)and conventional ileostomy(conventional group),respectively,performed by a single surgeon.Patient demographics,operative characteristics,postoperative outcomes,and 30-d morbidities and mortality rates were analyzed.RESULTS The two groups had comparable mean ages,sex distributions,American Society of Anesthesiologists scores,and body mass indices.However,the laparoscopic group showed similar operative time,better visualization for adhesion lysis,and lower visual analog scale scores than the conventional group.CONCLUSION Laparoscopy-assisted ileostomy is a safe and efficient method that produces lower visual analog scale scores,better intraoperative visualization for effective adhesion lysis,and similar operative time compared with conventional ileostomy.
