[Total colonic exclusion plus side to side ileorectal antiperistaltic anastomosis in the treatment for elderly patients with slow transit constipation].

OBJECTIVE: To evaluate the feasibility and safety of total colonic exclusion plus side to side antiperistaltic ileorectal anastomosis in the treatment for elderly patients with slow transit constipation (STC).

METHODS: Clinical data of 13 patients with severe idiopathic STC undergoing the above novel procedure in Zhongnan Hospital of Wuhan University between May 2009 and September 2012 were retrospectively analyzed. The Wexner constipation score and gastrointestinal quality of life index (GIQLI) before and 6 months after operation were compared.

RESULTS: There were 8 female and 5 male patients, with a mean age of 74 years (range 63-82 years). No procedure-related deaths or any serious complication occurred. The length of follow-up ranged from 6 to 29 months (median,12 months). The duration of surgery was (55±4) min. Blood loss was (30±2) ml. The postoperative hospital stay ranged 10 to 16 days (mean 11.4 days). The first bowel movement occurred in the 4th day (range 2nd-8th day) after operation. There was no intestinal occlusion and anastomotic leakage that required surgery in all the patients. No fecal incontinence or constipation recurrence was found. One patient developed blind loop syndrome 14 months after operation. Postoperative complications included incision fat liquefaction in 2 cases, anorectal bearing-down while bowel movement in 2 cases, and minor defecate difficulty needed glycerin enema in 1 case. Wexner scores was significantly improved from 22.8±3.3 before operation to 5.4±2.1 six months after operation (P<0.05). GQLI was significantly increased from 93.6±20.5 before operation to 120.8±13.0 six months after operation (P<0.05). At 6 months after operation, the outcome was excellent in 11 patients and good in 2 patients.

CONCLUSION: Total colonic exclusion plus side to side antiperistaltic ileorectal anastomosis is easy, safe and effective in the treatment for selected elderly patients with STC.
