METHODS： A prospective randomized controlled study was undertaken to evaluate the ability of these 2 agents to achieve high level disinfection in a gastroscope. A total of 260 samples were collected from 5 different gastroscopes. Manual cleaning was done for 10 min with these 2 agents separately （n = 130 each）. Then all specimens underwent 2% glutaraldehyde soaking for 20 min. After 70% alcohol was rinsed, sterile normal saline was flushed into each gastroscope channel and 40 mL of sample was collected. The sample was sent for aerobic bacterial culture after membrane was filtered. A colony count greater than 200 cfu/mL was considered significant. RESULTS： The positive culture rate was 4.6% in the enzymatic detergent arm and 3.1% in the chlorhexidine arm. Pseudomonas species were the main organism detected from both groups （60%）. Multiple organisms were found from 4 specimens （enzymatic detergent arm = 1, chlorhexidine arm = 3）. CONCLUSION： The contamination rate of both types of cleaning solution is equivalent.展开更多

Methods： We retrospectively analyzed the clinical data of 24 consecutive patients （22 with esophageal leiomyoma and 2 with esophageal mesenchymoma） who underwent gas-troscope-assisted thoracoscopic surgery. There were 17 male and 7 female with a mean age of 36 years. The tumors were located in the upper and middle part of the esophagus in 17 cases and lower part in 7 cases. Results： All 24 procedures were successfully performed. The median operative time was 84 minutes and the median hospital stay was 7.5 days. One esophageal perforation due to dissection of a large lesion occurred intraoperatively, which was repaired by suturing. No deaths or other severe postoperative complications were encountered during the median follow-up period of 20.5 months. Conclusion： Gastroscope-assisted thoracoscopic surgery provides a safe and effective alternative to open thoracotomy in the treatment of benign esophageal tumors.展开更多

diagnosis,treatment,follow-up review and other aspects of gastric cancer patients.The application of anesthesia techniques during manipulation can be effective in reducing patient fear and discomfort.In clinical work,the adverse drug reactions of anesthesia regimens and the risk of serious adverse drug reactions are increased with the increase in propofol application dose application dose;the application of opioid drugs often causes gastrointestinal reactions,such as nausea,vomiting and delayed gastrointestinal function recovery,after examination.These adverse effects can seriously affect the quality of life of patients.AIM To observe the effect of modified ShengYangYiwei decoction on gastrointestinal function,related complications and immune function in patients with gastric cancer during and after painless gastroscopy.METHODS A total of 106 patients with gastric cancer,who were selected from January 2022 to September 2022 in Xiamen Traditional Chinese Medicine Hospital for painless gastroscopy,were randomly divided into a treatment group(n=56)and a control group(n=50).Before the examination,all patients fasted for 8 h,provided their health education,and confirmed if there were contraindications to anesthesia and gastroscopy.During the examination,the patients were placed in the left decubitus position,the patients were given oxygen through a nasal catheter(6 L/min),the welling needle was opened for the venous channel,and a multifunction detector was connected for monitoring electrocardiogram,oxygen saturation,blood pressure,etc.Naporphl and propofol propofol protocols were used for routine anesthesia.Before anesthesia administration,the patients underwent several deep breathing exercises,received intravenous nalbuphine[0.nalbuphine(0.025 mg/kg)],followed by intravenous propofol[1.propofol(1.5 mg/kg)]until the palpebral reflex disappeared,and after no response,gastroscopy was performed.If palpebral reflex disappeared,and after no response,gastroscopy was performed.If any patient developed movement,frowning,or hemodynamic changes during the operation(heart rate changes during the operation(heart rate increased to>20 beats/min,systolic blood pressure increased to>20%of the base value),additional propofol[0.propofol(0.5 mg/kg)]was added until the patient was sedated again.The patients in the treatment group began to take the preventive intervention of Modified ShengYangYiwei decoction one week before the examination,while the patients in the control group received routine gastrointestinal endoscopy.The patients in the two groups were examined by conventional painless gastroscopy,and the characteristics of the painless gastroscopies of the patients in the two groups were recorded and compared.These characteristics included the total dosage of propofol during the examination,the incidence of complications during the operation,the time of patients'awakening,the time of independent activities,and the gastrointestinal function of the patients after examination,such as the incidence of reactions such as malignant vomiting,abdominal distension and abdominal pain,as well as the differences in the levels of various immunological indicators and inflammatory factors before anesthesia induction(T0),after conscious extubation(T1)and 24 h after surgery(T2).RESULTS There was no difference in the patients’general information,American Society of Anesthesiologist classification or operation time between the two groups before treatment.In terms of painless gastroscopy,the total dosage of propofol in the treatment group was lower than that in the control group(P<0.05),and the time of awakening and autonomous activity was significantly faster than that in the control group(P<0.05).During the examination,the incidence of hypoxemia,hypotension and hiccups in the treatment group was significantly lower than that in the control group(P<0.01).In terms of gastrointestinal function,the incidences of nausea,vomiting,abdominal distension and abdominal pain in the treatment group after examination were significantly lower than those in the control group(P<0.01).In terms of immune function,in both groups,the number of CD4+and CD8+cells decreased significantly(P<0.05),and the number of natural killer cells increased significantly(P<0.05)at T1 and T2,compared with T0.The number of CD4+and CD8+cells in the treatment group at the T1 and T2 time points was higher than that in the control group(P<0.05),while the number of natural killer cells was lower than that in the control group(P<0.05).In terms of inflammatory factors,compared with T0,the levels of interleukin(IL)-6 and tumor necrosis factor-alpha in patients in the two groups at T1 and T2 increased significantly and then decreased(P<0.05).The level of IL-6 at T1 and T2 in the treatment group was lower than that in the control group(P<0.05).CONCLUSION The preoperative use of modified ShengYangYiwei decoction can optimize the anesthesia program during painless gastroscopy,improve the gastrointestinal function of patients after the operation,reduce the occurrence of examination-related complications.展开更多

The status and the positive rate of Helicobacter pylori 13C urea breath test and compared two groups of patients with infection;using enzyme-linked immunosorbent assay of serum pepsinogen I (PG I), II (PG II) and pepsin Hp-IgG quantitative and qualitative diagnosis of individual and combined diagnostic efficiency and the comparison of three kinds of index.Results: The four groups were compared, the serum PG level of I from high to low were superficial gastritis group, normal control group, atrophic gastritis group and gastric cancer group, the differences were statistically significant;serum PG II levels from high to low in gastric cancer group and superficial gastritis group. Atrophic gastritis group, normal control group, the differences were statistically significant. Compared with the three groups, the positive rate of Hp-IgG was 90.7% in the gastric cancer group, 45.6% in the superficial gastritis group, 52.5% in the atrophic gastritis group, and the gastric cancer group was higher than that in the precancerous lesion group, but there was no difference between the precancerous lesions group. In terms of diagnostic efficacy, the specificity and sensitivity of Helicobacter pylori combined with pepsinogen were higher than those of the single diagnosis. Conclusion: Hp-IgG and PG combined with gastroscopy in screening high-risk gastric cancer and its precancerous lesions are of high specificity, high sensitivity and can be popularized in clinic.展开更多
