Hand-Assisted versus Straight-Laparoscopic versus Open Proctosigmoidectomy for Treatment of Sigmoid and Rectal Cancer: A Case-Matched Study of 100 Patients

Objective: The laparoscopic approach is increasingly used for surgical treatment of colorectal cancer. The aim of this study was to assess the efficacy of laparoscopic proctosigmoidectomy for cancer treatment by comparing postoperative outcomes among three groups: hand-assisted laparoscopic resection, conventional straight-laparoscopic resection, and open resection.
