METHODS： Fourteen patients （mean age 57.5±16.5 year） underwent surgery for isolated CI between January 1986 and December 2002. The mean frequency of bowel motions with the aid of laxatives was 1.2±0.6 per week. All subjects underwent colonoscopy, anorectal manometry, cinedefaecography and colonic transit time （CTF）. CI was defined as diffuse markers delay on CTF without evidence of pelvic floor dysfunction. All patients underwent STC-CRA. Long-term follow-up was obtained prospectively by clinical visits between October 2005 and February 2006 at a mean of 10.5 ＋ 3.6 years （range 5-16 years） during which we considered the number of stool emissions, the presence of abdominal pain or digitations, the use of pain killers, laxatives and/or fibers. Patients were also asked if they were satisfied with the surgery. RESULTS： There was no postoperative mortality Postoperative complications occurred in 21.4% （3/14）. At the end of follow-up, bowel frequency was significantly （P〈0.05）increased to a mean of 4.8±7.5 per day （range 1-30）. One patient reported disabling diarrhea. Two patients used laxatives less than three times per month without complaining of what they called constipation Overall, 78.5% of patients would have chosen surgery again if necessary. CONCLUSION： STC-CRA is feasible and safe in patients with CI achieving 79% of success at a mean follow-up of 10.5 years. A prospective controlled evaluation is warranted to verify the advantages of this surgical approach in patients with CI.展开更多

However, the roles of AQPs in the GI tract remain unclear. Materials and Methods: Male SD rats were subjected to subtotal colectomy (Group C, n = 22) or a sham operation (Group S, n = 16) and were sacri-ficed on postoperative days 7, 14, and 28. Total RNAs from the distal ileum and rectum were extracted. Quantitative RT-PCR was performed to measure AQP8 mRNA expression. For light-microscopy or immunohistochemistry, paraffin-embedded sections of 4 μm were prepared with H-E staining or anti-AQP8 antibody reaction. Mann-Whitney U-test was performed to compare the AQP8 distributions between the two groups, and the statistical significance was defined as展开更多

A subset of patients who underwent TP even died due to severehypoglycemia. For pancreatic cancer involving the pancreatic head and proximalbody but without invasion to the pancreatic tail, we performed partial pancreatictail preserving subtotal pancreatectomy (PPTP-SP) in selected patients, in order toimprove postoperative glycemic control and QoL without compromisingoncological outcomes.AIM To evaluate the efficacy of PPTP-SP for patients with pancreatic cancer.METHODS We retrospectively reviewed 56 patients with pancreatic ductal adenocarcinomawho underwent PPTP-SP (n = 18) or TP (n = 38) at our institution from May 2014to January 2019. Clinical outcomes were compared between the two groups, withan emphasis on oncological outcomes, postoperative glycemic control, and QoL.QoL was evaluated using the European Organization for Research and Treatmentof Cancer Quality of Life Questionnaire (EORTC QLQ-C30 and EORTC PAN26).All patients were followed until May 2019 or until death.RESULTS A total of 56 consecutive patients were enrolled in this study. Perioperativeoutcomes, recurrence-free survival, and overall survival were comparablebetween the two groups. No patients in the PPTP-SP group developed cancerrecurrence in the pancreatic tail stump or splenic hilum, or a clinical pancreaticfistula. Patients who underwent PPTP-SP had significantly better glycemiccontrol, based on their higher rate of insulin-independence (P = 0.014), lowerhemoglobin A1c (HbA1c) level (P = 0.046), lower daily insulin dosage (P < 0.001),and less frequent hypoglycemic episodes (P < 0.001). Global health was similar inthe two groups, but patients who underwent PPTP-SP had better functional status(P = 0.036), milder symptoms (P = 0.013), less severe diet restriction (P = 0.011),and higher confidence regarding future life (P = 0.035).CONCLUSION For pancreatic cancer involving the pancreatic head and proximal body, PPTP-SPachieves perioperative and oncological outcomes comparable to TP in selectedpatients while significantly improving long-term glycemic control and QoL.展开更多

METHODS From January 2016 to March 2017,a total of 20consecutive patients with colon cancer accepted TLC and the ODA technique at our medical center.Patient demographics,operative outcomes,perioperative complications,and pathological results were collected and analyzed. RESULTS We successfully completed TLC and the ODA procedure in all 20 cases,including 6(30%)males and 14(70%)females.In total,11(55%),2(10%),and 7(35%)cases accepted right hemicolectomy,transverse hemicolectomy,and left hemicolectomy,respectively.None of the surgeries were converted to an open operation.Mean operative time was 178.5 min,and mean estimated blood loss was 58.5 m L.Mean time to first flatus was 2.5 d,and mean postoperative hospitalization duration was 6.8 d.No severe complications occurred,such as anastomotic leakage,snastomotic stenosis,anastomotic bleeding,and wound infection,except for one case who suffered from an abdominal infection and another case who suffered from gastric paralysis syndrome.Tumor recurrence was not observed in any patient during the follow-up period. CONCLUSION The ODA technique for colon cancer cases undergoing TLC appears to be safe and feasible,although our current results need to be verified in further studies.展开更多

After a precise instrumental work-up, the patient was selected as a potential candidate for the surgical treatment after failing to respond to all other medical treatment. During the first three months following the surgery, the patient recorded 3 - 4 daily evacuations of soft stool. After the third month, the number of evacuations stabilised at 2 -?3 a day, with formed stool, and no mention of incontinence or abdominal pain. Although the laparoscopic total colectomy with ileorectal anastomosis (TC with IRA) and the laparoscopically assisted subtotal colectomy with cecorectal anastomosis (SC with CRA) are the most frequently practiced procedures in the surgical treatment of chronic constipation, the laparoscopic colectomy with ileal j-pouch has shown in our experience to be a feasible and effective procedure, with similar results to the two aforementioned procedures in terms of morbidity, mortality and quality of life. In fact, like the first two, the total colectomy with ileal j-pouch has demonstrated the advantages of laparoscopic surgery: low invasiveness, less post-operative pain or ileus, respect of parietal integrity, reduced hospitalization and, lastly, a better cosmesis.展开更多

文摘Background:Surgical management of adult slow-transit constipation(ASTC)can be effective for patients with intractable symptoms.This study aimed to evaluate whether barium-strip examination and selective colectomy improved post-operative outcomes in ASTC patients in comparison with subtotal colectomy.Methods:A retrospective cohort study of 53 cases with refractory ASTC was conducted between June 2008 and June 2014.Patients were evaluated by the barium-strip technique,colonoscopy,defecography and anorectal manometry.Patients in the standard group underwent laparoscopic subtotal colectomy and patients in the laparoscopic selective colectomy(LSC)group underwent LSC at the precise location identified by barium strip.Spontaneous bowel movements,the Wexner Constipation Scale and the Gastrointestinal Quality of Life Index(GIQLI)were assessed post-operatively at 3,6,12 and 24 months.Results:A total of 49 patients were included in the analysis.The median follow-up was 37 months(range,26–60 months).The mean post-operative hospital stay was 12 days and similar between groups(P=0.071).The length of colon resection,operative time and intra-operative blood loss were reduced in the LSC group(all P<0.05).No major complications occurred.A similar number of patients(24 in the standard group and 25 in the LSC group)exhibited hypoganglionosis or aganglionosis in the colon-wall muscle layer(P=0.986).Although there were no significant differences in post-operative spontaneous bowel movements and the Wexner Constipation Scale between the two groups,the mean GIQLI of the LSC group was significantly higher at 3,6 and 24 months post-operatively(all P<0.05).Conclusions:LSC based on barium-strip examination is an appropriate modality for treating ASTC.
