Effects of laparoscopic sleeve gastrectomy on early complications and 1-year comorbidity in a single center, single surgeon cohort of 342 patients

Abstract

Aim: The purpose of this study was to examine the 30-day morbidity and mortality rates after Laparoscopic Sleeve Gastrectomy (LSG) over a 5-year period. Material and Methods: A retrospective analysis was conducted using prospectively collected data from patients who underwent LSG by the same surgeon between July 2017 and August 2022. The study identified LSG-related 30-day morbidity and mortality rates, as well as risk factors for 30-day morbidity. Furthermore, the impact of comorbidities on patients was evaluated at the 1-year follow-up. Results: The study analysed the outcomes of 342 patients who underwent laparoscopic sleeve gastrectomy (LSG) over a period of five years. Early postoperative complications were experienced by 11.40% of patients (39 individuals), with six patients requiring blood transfusions, and 2.34% of patients (eight individuals) requiring readmission to hospital. The reoperation rate was 0.87% (three individuals) and the mortality rate was 0.29% (one individual). The study identified body mass index, diabetes, and hypertension as significant factors contributing to early postoperative complications. Technical term abbreviations were defined upon first use. At the six-month follow-up, patients demonstrated an average body weight loss of 62.9 +/- 16.17%. Discussion: The previously reported short-term safety of LSG, in terms of low 30-day postoperative morbidity and mortality rates, was confirmed by this study. Preoperative BMI, diabetes, and hypertension were found to be risk factors for 30-day morbidity and mortality. Additionally, an average 80% improvement in comorbidities was observed at one year.
