Abstract: Objective To preliminarily evaluate the feasibility, safety and short-term clinical efficacy of three-port laparoscopic sleeve gastrectomy (TPLSG). Methods The clinical data of 39 patients performed laparoscopic sleeve gastrectomy (LSG) between January and July 2018 in our hospital were analyzed retrospectively. There were 20 patients with TPLSG and 19 patients with routine five-port LSG. The operative time and blood lost, surgical complications, postoperative pain and hospital stay, percentage of excess weight loss at 3 months postoperatively were compared between TPLSG and LSG. Results Less postoperative pain and reduced postoperative hospital stay in TPLSG group were found when compared with those in LSG group (P<0.05). There was no significant difference in operative time, operative blood loss, surgical complications and percentage of excess weight loss at 3 months postoperatively between two groups (P>0.05). Conclusions TPLSG would be a safe and effective surgical procedure which could accelerate the perioperative recovery and reduce hospital length of stay.
