the effect of staple line reinforcement procedures on postoperative nausea and vomiting in sleeve gastrectomy

Conditions: Bariatric Surgical Procedures; Nausea, Postoperative; Vomiting, Postoperative

Summary: obesity is a significant public health problem. the only long-term effective treatment method is surgery. the most common surgical procedure is laparoscopic sleeve gastrectomy (lsg). however, after lsg, complications such as gastroesophageal reflux disease (gerd), insufficient weight loss, stenosis in the remnant stomach, and bleeding or leakage in the staple line (sl) may be encountered. the most severe complications are leakage and bleeding in sleeve gastrectomy, which can lead to many morbidities and mortality. strengthening the staple line is an important option to prevent these complications. methods such as fibrin adhesives, bioabsorbable patches and stitching of the stapler line are used to strengthen the stapler line. nausea and vomiting, which occur in the postoperative period in 40% of patients who have undergone abdominal surgery and constitute a serious problem, are detected at an even higher rate in patients who have undergone bariatric surgery. additionally, strengthening the staple line with various methods may increase the incidence of nausea and vomiting after lsg. although there are studies in the literature investigating whether strengthening the staple line with buttress material or suture in laparoscopic sleeve gastrectomy affects the incidence of postoperative nausea and vomiting, there is no study investigating the effect of strengthening the staple line with fibrin glue on the incidence of postoperative nausea and vomiting. this prospective study aims to reveal whether there is a difference between strengthening the staple line with fibrin glue or suture in lsg regarding the incidence of postoperative nausea and vomiting and its effects on quality of life.

bleeding and leaks may occur in the stapler line after sleeve gastrectomy. to prevent these complications, the staple line can be strengthened. more than 60% of bariatric surgeons perform interventions to strengthen the staple line in sleeve gastrectomy. two surgeons will perform the operations. one of the surgeons will suture the staple line. the other will apply fibrin glue to the stapler line. study: it will be held between june 2023 and june 2024. the same anaesthesia protocol will be applied to all patients during the surgery; all patients will be administered fentanyl 2 mg kg-1, propofol 2.5 mg kg-1 and rocuronium 0.6 mg kg-1 based on lean body weight (lbw) for anaesthesia induction after 3 minutes of preoxygenation. after orotracheal intubation is performed under the guidance of a video laryngoscope and endotracheal intubation is confirmed, 1.0 minimum alveolar concentration (mac) value sevoflurane and 1:1 oxygen-air will be used for anaesthesia maintenance. additional doses of rocuronium were administered if surgically necessary. ventilation will be applied with a tidal volume of 6-8 ml kg-1 according to the ideal body weight for lung protective ventilation, along with a respiratory frequency at a level to ensure normocapnia (etco2 35-45 mmhg). for intraoperative analgesia, remifentanil infusion will be administered at a 0.1-0.3 mcg kg-1 min-1 dose according to ideal body weight. all patients will be given 0.15 mg kg-1 (maximum 16 mg) of ondansetron as an antiemetic. in recovery, sugammadex will be used at a 4-8 mg kg-1 dose to reverse the neuromuscular blockade. for acute postoperative analgesia, 100 mg tramadol, 1000 mg paracetamol and 50 mg dexketoprofen will be administered. no routine postoperative antiemetic medication will be used. quality of life index and nausea and vomiting score survey forms will be filled out for patients in the preoperative period, at the 6th, 24th hour and 1st postoperative hour. according to these filled-out forms, the patient's nausea and vomiting scores and quality of life scores will be calculated. patients included in both groups will be compared to these scores. this study aims to determine whether there is a difference in strengthening the staple line with fibrin glue or sutures in sleeve gastrectomy regarding the incidence of postoperative nausea and vomiting and its effects on quality of life.
