Abstract
RESULTS: Fifty six obese patients (mean age, 59.5 10 years) underwent RS or LS for rectal cancer. There were 29 and 27 patients in the RS and LS group, respectively. Both groups were comparable in terms of demographics, BMI (35 7 vs 35 5 kg/m, p1⁄40.71), co-morbidities, surgical and tumor characteristics. Comparison of the intraoperative findings revealed no significant differences including operative time (329 102 vs 295 81 min, p1⁄40.13), blood loss (434 612 vs 339 272 ml, p1⁄40.68), tumor distance to distal margin (4 2 vs 3 2 cm, p1⁄40.17), radial involvement (7% vs 7%, p1⁄40.99), conversion (3% vs 19%, p1⁄40.09), intraoperative complications (7% vs 0%, p1⁄40.49). Regarding postoperative outcomes, there were no significant differences regarding surgical site infections, sepsis, ileus, pulmonary and urinary complications. Other outcomes were also similar except that RS was associated with quicker return of bowel function (3 vs 4 days, p1⁄40.01) and shorter hospital stay (6 vs 7 days, p1⁄40.02).
