yBackgroundzLaparoscopic anterior resection would be beneficial not only cosmetic aspect and less invasiveness but also for postoperative bowel function compared to those of open surgery.
yMethodszTwenty patients had laparoscopic anterior resection (LAP) and pre- and
postoperative anorectal physiologic investigation by patientsf questionnaire and
manometry. These factors were compared with 25 open anterior resection candidate
(OP) in the same period. All patients had DST straight anastomosis. Patientsf
questionnaire was composed of frequency of bowel movement, any history of
incontinence and more. Wexnerfs incontinence score was used for objective measure.
Manometric study was performed with water perfuse type by station pull through
technique. Evaluation was obtained at pre- and 6 months postoperative period.
yResultszNo significant difference was noted in terms of age, gender and tumor stage. Time of operation was longer in the LAP. However, loss of operative blood was significantly smaller than that of the OP. Postoperative hospital stay of LAP was shorter than that of OP. In terms of anorectal function, anastomosis level was 5 cm from the anal verge in both groups. Frequency of bowel movement was increased equally in both groups (5 vs. 5 per day). Wexnerfs incontinence score also showed significant deterioration from 0 to 6. However, there was no significant difference.
Anorectal manometry showed no significant change in terms of anal resting and squeezing pressures. Maximum tolerable volume (100 vs. 96 ml) and rectal capacity (80 vs. 76 ml) were significantly decreased in both groups. However, there was no significant difference.
yConclusionzLaparoscopic anterior resection provided similar functional outcome to those of open surgery in the early postoperative periods.
