Hand-assisted laparoscopic colectomy: a single-institution experience.

The purpose of this study was to examine the results of a single institution experience with hand-assisted laparoscopic colon resection for benign disease. We conducted a retrospective study of consecutive cases performed by experienced laparoscopic surgeons at a single institution. From August 1999 to June 2001, 37 patients underwent hand-assisted laparoscopic colon resection. Seventeen patients were male, and 20 were female. Median patient age was 58 years (range 20-80). Indications for surgery were: polyp (13), uncomplicated diverticular disease (eight), complicated diverticular disease (i.e., colovesicular fistula, phlegmon, etc.) (seven), chronic constipation (four), rectal prolapse (two), ulcerative colitis (one), endometriosis (one), and fecal incontinence (one). Procedures performed were: sigmoidectomy (14), right colectomy (nine), low anterior resection (seven), subtotal colectomy (five), cecectomy (one), and transverse colectomy (one). Variables examined were: conversion to open procedure, operative time, blood loss, time to return of flatus, length of postoperative hospital stay, and complications. There were no deaths. One case was converted to celiotomy (unable to rule out malignancy). The median operative time was 122 minutes (range 32-240) with a median operative blood loss of 132 mL (range 0-300). Return of flatus was noted (median) at postoperative day 3 (range 1-5), and the median length of stay after operation was 4 days (range 2-8). One patient developed a superficial wound infection, and there was one pelvic abscess (drained percutaneously). One patient developed urinary retention. There were no reoperations. In this single-institution experience hand-assisted laparoscopic elective colectomy for benign disease was successful in both straightforward and complicated cases. A low conversion rate to celiotomy and favorable operative times compared with published "pure" laparoscopic results suggest a flatter learning curve for handoscopy while retaining the benefits of "minimally invasive" surgery such as early return of flatus and short postoperative hospital stay. For these reasons hand-assisted laparoscopy should be considered an acceptable technique in elective colon resection for benign disease.
