Objective To analyze the efficacy of modified transvaginal rectal repair(MTVRR)in patients with moderate to severe rectocele(RC).Methods A retrospective analysis was conducted on the clinical data of 21 female patients with RC who underwent MTVRR.The Constipation Scoring System(CSS)scale was used to assess patients'constipation symptoms before surgery and at 3,6,12 and 24 months after surgery,and the efficiency of symptom improvement was recorded.The occurrence of postoperative complications in RC patients was observed.Results All 21 patients successfully un-derwent the surgery,with surgical duration ranging from 25 to 135 minutes,with average of(83.14±30.39)minutes,and hospital stay ranging from 10 to 21 days,with average of(14.10±2.34)days.Postoperatively,one patient was lost during follow-up among 21 patients.The CSS scores of the remai-ning 20 patients were lower than those before surgery,with a statistically significant difference(P＜0.05).The overall effective rates of constipation symptom improvement at 3,6 and 12 months postop-eratively were 100.00％,90.00％and 80.00％,respectively.Among 20 patients,15 patients com-pleted 24-month follow-up after surgery,and the CSS score after surgery was lower than that before sur-gery,the difference was statistically significant(P＜0.05).The CSS scores of the remaining 15 pa-tients were lower than those before surgery,with a statistically significant difference(P＜0.05).The overall effective rate of constipation symptom improvement at 24 months postoperatively was 80.00％among 15 patients.During postoperative follow-up,it revealed that no complications occurred in any patient.Conclusion MTVRR can improve constipation symptoms in patients with RC,demonstra-ting good therapeutic efficacy.

ObjectiveTo investigate the effects of probiotics combined with bismuth quadruple therapy （BQT） on clinical efficacy、gastrointestinal adverse reactions and intestinal flora in Helicobacter pylori （HP） positive patients. MethodsThe patients who were positive for HP from May 2023 to July 2023 in the department of gastroenterology of Shanghai first people's hospital were randomly divided into2 groups with 40 people in each group. The probiotic group was given 2 weeks of quadruple therapy with probiotics and standard BQT， followed by 4 weeks of oral probiotics after quadruple discontinuation. The placebo group was given 2 weeks of probiotic placebo and standard BQT， followed by 4 weeks of oral probiotic placebo. ¹³C urea breath test was used to evaluate the clinical efficacy， gastrointestinal symptoms rating Scale was used to evaluate the gastrointestinal adverse reactions of patients before and after the intervention， and microbial diversity 16S rDNA sequencing technology was used to detect the level of intestinal flora of patients before and after the intervention. ResultsThere was no significant difference in the eradication rate between the two groups （P>0.05）. Before the intervention， there was no significant difference in the scores of the gastrointestinal symptom rating scale between the probiotic group and the placebo group. After the intervention， patients in the probiotic group had significantly lower pain scores on acid reflux （1.10±0.30 vs 1.35±0.53， P<0.05） and stomach or abdominal hunger than in the placebo group （1.07±0.26 vs 1.30±0.52， P<0.05）. Through the before-and-after comparison of the probiotic group， the scores of abdominal pain （1.24±0.44 vs 1.58±0.71， P<0.05）， stomach or abdominal hunger （1.07±0.26 vs 1.27±0.45， P<0.05） and dry and hard stool （1.24±0.49 vs 1.48±0.75，P<0.05） were significantly lower in the probiotic group than before the intervention in the probiotic group. ConclusionProbiotics combined with BQT can improve the gastrointestinal adverse reactions and intestinal flora disorders in the process of quadruple drug therapy， but it does not improve the eradication rate of HP.
