Abstract
Background:
Sex may play an essential role in predicting outcomes after bariatric surgery. This study aimed to investigate the influence of sex on short- and long-term outcomes after laparoscopic sleeve gastrectomy (LSG).
Method:
The primary LSG (N = 3761) was evaluated from 2005 to 2020. Data were compared between men (N = 1217) and women (N = 2544). Outcome criteria were perioperative morbidity, postoperative complications, and remission of comorbidities after a 3-year follow-up.
Results:
Male patients were significantly older (46.2 years vs. 43.8 years) and heavier (167.1 kg vs. 138.6 kg) than female patients. Intraoperative bleeding, postoperative bleeding requiring transfusion, and surgery occurred more frequently in men than in women (p = 0.041, p = 0.005, and p < 0.001, respectively). Operating time and length of hospital stay were longer in men than in women. Percent excess weight loss (%EWL) was 63.6 ± 25.2 in women and 58.4 ± 24.9 in men (p < 0.001). A significant difference in favor of women was observed in remission of hypertension (p < 0.001).
Conclusions:
In both sexes, LSG is effective in treating obesity. The male sex may have an adverse effect on the outcome of bariatric surgery. However, this tendency has not been clearly elucidated, and further scientific studies are needed.
