Objective To investigate the safety and feasibility of the total mesorectal excision （TME） and intersphincteric resection （ISR） for ultra-low rectal cancer and anal sphincter preservation surgery for anorectal cancer， and to evaluate the short term efficacy and postoperative anal function. Methods A retrospective analysis of clinical and follow-up data of 86 cases with TME＋ISR for ultra-low rectal cancer and anorectal cancer from January 2009 to December 2010 in West China Hospital of Sichuan University were performed. Results Eighty-six patients were successfully performed the operation， the lower edge of tumor from the anus was 1-5 cm （average 1.63cm）； tumor diameter was 2-7 cm （average 3.4cm）. The tumors were high differentiation in 4 cases， moderately differentiation in 60 cases，and poorly differentiation in 22 cases. The pTNM stages were stageⅠin 12 cases， stageⅡA in 11 cases， stage ⅡB in 15 cases， stage ⅢA in 2 cases， stage ⅢB in 23 cases， stage ⅢC in 16 cases， and stage Ⅳ in 7 cases. There were postoperative anastomotic leakage in 3 cases， perianal infection in 2 cases （1 case received reoperation with permanent colostomy because of pelvic peritoneal infection caused by perianal severe infections）. Anastomotic bleeding and anastomotic stenosis were of 2 cases respectively. Rectovaginal fistula， inflammatory ileus， urinary retention， and abdominal infection were of 1 case respectively. Eighty-six patients were followed-up for 12-24 months， the mean time was 18 months. Liver metastases was found in 1 case in 7 months after operation， 2 cases dead in the 7th month and 12th month after operation respectively. Local recurrence were found in 3 cases （3.5%） in 1 year after operation. The survival rate of 1-year was 97.7% （84/86）. The times of defecation was 1-5 times a day. The Kirwan’s score level on function of control defecation was 1-2 grade. Conclusions TME＋ISR for low rectal cancer and anorectal cancer is a viable， safe， and radical operation type for preservation of anus. The short term efficacy is satisfactory.
Objective To investigate clinical effects of modified Xiaozhiling injection with anal cushion suspensory fixation in treatment of prolapsed hemorrhoids. Methods From January 2012 to June 2013, 150 hospitalized patients with Ⅱ and Ⅲ degrees internal hemorrhoids and mixed hemorrhoid, with prolapsing as the main clinical manifestations, were included prospectively, then subsequently randomly divided into a modified Xiaozhiling injection with anal cushion suspensory fixation group (observation group), a procedure for prolapse and hemorrhoids (PPH) group, and a classic Milligan-Morgan surgery (M-M) group. The Xiaozhiling injection with saline by 1:1 mixture was injected into the rectum submucosa and perirectal gap and the anal cushion suspensory fixation were performed for the treatment of prolapsed hemorrhoids in the observation group. The operations of the PPH group and M-M group were same as the convention. The treatment effect, hospitalization time, hospital expenses, postoperative complications, and recurrence were compared among these 3 groups. Results ① Fourty-nine cases were cured and 1 case was improved in the observation group, 48 cases were cured and 2 cases were improved in the PPH group, 48 cases were cured and 2 cases were improved in the M-M group, the treatment effects had no significant differences among these 3 groups (χ2=0.411, P=0.814). ② The hospitalization time and hospitalization expenses of the observation group were significantly less than those of the PPH group (P<0.001) and the M-M group (P<0.001). ③ No prolapse of hemorrhoids and infection happened on day 1, 2, 3, 7, and 14 among these 3 groups. The pains of the observation group were slighter on day 1, 2, 3, 7, and 14 as compared with the PPH group (except on day 14,P<0.05) and the M-M group (P<0.05). The anus bulges had no significant difference between the observation group and the PPH group (except on day 1,P>0.05), which of the observation group were significantly slighter than those of the M-M group (P<0.05). The bleeding on day 2 and 3 and the perianal edema on day 3 had no significant difference between the observation group and the PPH group (P>0.05), which of the observation group were significantly slighter than those of the M-M group (P<0.05). The urinary retention had no significant difference on day 1–3 among these 3 groups (P>0.05). ④ The anal stenosis, anal continence, and hemorrhoids recurrence on month 1, 6, and 12 had no significant differences among these 3 groups (P>0.05). Conclusions Modified Xiaozhiling injection with anal cushion suspensory fixation in treatment of prolapsed hemorrhoids could effectively make anal cushion fixation, eliminate main symptoms of bleeding and prolapse, preserve anal function well. It’s clinical efficacy is same as PPH and M-M methods, with a shorter hospitalization time, less hospitalization expenses, milder postoperative complications, and lower recurrence rate.
Objective To investigate the operating skills for treatment of morbidly obese patients with gallstone by using laparoscopic technique meanwhile. Methods From Oct.2006 to Nov.2009, 178 morbidly obese patients undergoing laparoscopic adjustable gastric banding （LAGB）, in which 18 cases combined with gallstone underwent laparoscopic cholecystectomy （LC） meanwhile. Results All of 18 morbidly obese patients with gallstone underwent LAGB and LC successfully, the operating time was (126±24) min and bleeding volume was (50±16) ml. No serious infectious complications occurred, but 3 cases with low-grade nausea and vomiting, 2 cases with adipose tissue liquefaction in incision, and one case with few seroperitoneun， all were cured conservatively. Conclusion Morbidly obese patients with gallstone undergoing LAGB and LC at the same time by changing site of incision is a safe and effective procedure and a feasible technique.
