Effect of preoperative liraglutide 3.0mg on incidence of intraoperative adhesions in laparoscopic sleeve gastrectomy.

Abstract

Liraglutide has shown promising results in the field of bariatric surgery, preparing patients for surgery. However, chronic therapy is often correlated with gastrointestinal disorders, such as subclinical pancreatitis. The aim of this study was to evaluate the incidence of intraoperative adhesions and post-operative complications in patients undergoing laparoscopic sleeve gastrectomy (LSG) with or without prior therapy with liraglutide. Clinical records of patients affected by obesity who underwent LSG between March 2017 and October 2022 were retrospectively reviewed using a prospectively maintained database. Patients were separated into two groups: those managed with preoperative liraglutide for 24weeks prior to LSG, and those without prior medical therapy. Demographic data, operative time, intraoperative adhesions, and postoperative complications were reported and compared between two groups. Ninety-three patients underwent LSG without prior medical therapy, while 87 were treated with liraglutide before surgery. There were no significant differences in terms of gender, age, and comorbidities. After treatment with liraglutide, weight (117 vs 109kg) and BMI (45 vs 42.2kg/m2) were statistically lower than the group with no prior treatment to surgery. Thirty-two (37%) patients of the group treated with liraglutide had intraoperative adhesion vs nine (10%) patients of the control group (p < 0.005). There were no differences recorded between the two groups concerning post-operative complications. Liraglutide has introduced a new way to treat obesity, improving weight loss and comorbidities. Gastrointestinal disorders, such as subclinical pancreatitis, associated with GLP-1 analogue could explain the elevated incidence of intraoperative adhesions during bariatric surgery.
