Laparoscopic Colorectal Surgery in Elderly Patients: A Matched Case-Control Study in 178 Patients

BackgroundWe conducted a prospective case-matched study to compare outcomes of laparoscopic colorectal surgery in elderly (≥ 70 years) and younger (< 70 years) patients.Study DesignAmong 506 consecutive patients who underwent 536 colorectal resections supervised by 1 colorectal surgeon (YP), 75 elderly patients (≥ 70 years)were matched with 103 younger patients (< 70 years), according to gender, body mass index, pathology, and surgical procedure. Postoperative mortality and morbidity were defined as in-hospital deaths and complications.ResultsOne hundred seventy-eight patients (95 men and 83 women) underwent laparoscopic colorectal resection for colorectal carcinoma (40%) or benign diseases (60%). Laparoscopic surgical procedures included left colectomy (43%), rectal resection (34%), right colectomy (12%), subtotal colectomy (6%), and rectopexy (5%). Cardiopulmonary comorbidities were significantly more frequent in elderly compared with young patients (80% versus 33%, p < 0.001). Mean operating times were similar between elderly and young patients (244 ± 89 minutes versus 242 ± 80 minutes, NS). Thirty-two patients (18%, 16 in each group) required conversion to laparotomy. There was no mortality. Overall postoperative complications were comparable between groups (32% versus 26%, NS). Sixteen patients (9%, 5 elderly and 11 young) required reoperation. Mean hospital stay was comparable between groups (11 ± 8 days versus 10 ± 9 days, NS).ConclusionsThis large case-matched study suggested that laparoscopic colorectal surgery may be proposed in elderly patients, with similar postoperative outcomes as this surgery has in young patients, despite significantly more frequent cardiorespiratory comorbidities.
