Research and application of the colon J-pouch and the transverse coloplasty pouch in low rectal cancers after anterior resection
2007
OBJECTIVE: To compare the two pouch reconstruction techniques of the colon J-pouch (CJP) and the transverse coloplasty pouch (TCP) in terms of bowel function in low rectal cancers after anterior resection. METHODS: Clinical-pathological data from 11 cases of CJP and 10 cases of TCP and 10 cases of the straight coloanal anastomosis (control) were analyzed retrospectively form March 2004 to May 2005. RESULTS: After 3 months of operation, maximum tolerable volume (198.6±18.9)mL, inducing cacation volume (142.9±13.0)mL, rectal compliance (5.5±0.9 mL/mmHg) were reduced in CJP, respectively, and the data of TCP and control were 160.5±14.6 mL, 108.2±7.8 mL, 5.2±0.6 mL/mmHg and 116.8±15.4 mL, 81.7±8.8 mL, 3.3±0.5 mL/mmHg. Maximum tolerable volume, inducing cacation volume and rectal compliance were significantly better after the colonic pouch reconstruction than after the straight anastomosis (P0.05). Maximum tolerable volume and inducing cacation volume were significantly better after CJP than after TCP (P0.05). There was no significant difference in the complications of the three techniques. CONCLUSION: It is suggested that CJP and TCP enlarge the volume of “neorectum”, raise the rectal compliance, improve bowel function and make better quality of life.
