BACKGROUND

The aim of this retrospective, case-matched controlled study was to determine the benefit of laparoscopic-assisted colectomy (LC) for the elderly (>75 years of age) and the young (<75 years of age) compared to an open colectomy (OC) control group.

METHODS

A retrospective review of 39 patients older than 75 years of age and 38 patients younger than 75 years of age who underwent LC for colorectal cancer between 1991 and 1999 was performed. LC patients were matched with an open control group for procedure, age, gender, year of procedure, and surgeon. Procedures included right and left colectomy, anterior resection of the rectosigmoid, and abdominoperineal resection. Measured intraoperative variables included anesthesia time, operative time, and estimated blood loss. Postoperative parameters consisted of duration of intravenous or epidural narcotic usage, return of bowel function (RBF), length of stay, and independence at discharge. These variables were compared in the entire group of 154 patients.

RESULTS

Mean ages were 81.4 and 81.8 years for LC and OC age >75 and 62.9 and 62.7 for LC and OC age <75. Mean anesthesia time and operative time were significantly longer (p < 0.05) for LC compared to OC (46.8 vs 39.3 and 159.3 vs 111.7 min, respectively) for age >75 and for age <75 (47.1 vs 40.3 and 182.8 vs 135.5 min, respectively). LC achieved faster recovery in both age groups: RBF (3.9 vs 4.9 days for age >75; 6.7 vs 7.7 days for age <75) (p < 0.05). Narcotic usage was shorter for the LC group age <75 (3.3 vs 4.4 days; p < 0.05). There was no significant difference in independence at discharge between LC and OC in either age group. Faster recovery was seen with left LC in age >75 and right LC in age <75 compared to OC.

CONCLUSION

The advantages of LC over OC are the same for the elderly and the young. There may be a selective benefit of laparoscopic left colectomy in the elderly and laparoscopic right colectomy in the young.
