Abstract

Background The indications for sleeve gastrectomy as a primary procedure for the surgical treatment of morbid obesity have increased worldwide. Pain is the most common complaint for patients on the first day after laparoscopic sleeve gastrectomy. There are various methods for decreasing pain after laparoscopic sleeve gastrectomy such as the use of intraperitoneal bupivacaine hydrochloride. This clinical trial was an attempt to discover the effects of intraperitoneal bupivacaine hydrochloride on alleviating postoperative pain after laparoscopic sleeve gastrectomy. Methods In general, 120 patients meeting the inclusion criteria were enrolled. Patients were randomly allocated into two interventions and control groups using a balanced block randomization technique. One group received intraperitoneal bupivacaine hydrochloride (30 cm3), and the other group served as the control one and did not receive bupivacaine hydrochloride. Diclofenac suppository and paracetamol injection were administered to both groups for postoperative pain management. Results The mean subjective postoperative pain score was significantly decreased in patients who received intraperitoneal bupivacaine hydrochloride within the first 24 h after the surgery; thus, the instillation of bupivacaine hydrochloride was beneficial in managing postoperative pain. Conclusions The intraoperative peritoneal irrigation of bupivacaine hydrochloride (30 cm3, 0.25%) in sleeve gastrectomy patients was safe and effective in reducing postoperative pain, nausea, and vomiting (IRCT2016120329181N4). © 2018 The Society for Surgery of the Alimentary Tract.
