Abstract
Objective
Some patients fail to maintain weight loss after bariatric surgery. Weight regain (WR) disturbs the patients due to possible reappearance of obesity-related comorbidities. This study aimed to assess WR 5 years after laparoscopic sleeve gastrectomy (LSG).
Patients and Methods
This retrospective study included 100 adults who underwent LGS. The percentage of excess weight loss (%EWL) was recorded. WR was defined as an increase of at least 10% of the lowest postoperative weight. Patients with WR were subjected to CT gastric volumety. Eating behavior was assessed by the Three-Factor Eating Questionnaire-Revised 18-Items (TFEQ-R18).
Results
Preoperative comorbidities improved in 89.5% of the patients. Twenty-five females (32.5%) got pregnant within 3 years after surgery. Age, maximum weight loss, and uncontrolled and emotional eating scales of the TFEQ-R18 were independently affecting %EWL. Also, pregnancy negatively affected %EWL. Fourteen patients regain weight: 11 females and three males. CT volumetry of the 14 patients showed a median stomach volume of 515 mL (range 172–1066 mL). CT estimated gastric volume was negatively correlated with % EWL (r = − 0.674, p = 0.008). Patients who developed WR were significantly older (p = 0.006), with lower maximum weight loss, and having higher scores of uncontrolled and emotional eating scales of TFEQ-R18.
Conclusion
Medium-term postsurgical weight regain and unsuccessful weight loss in patients who had undergone LSG is associated with older age, maladaptive eating behavior, larger residual stomach, and pregnancy.
