This study aims to investigate the causes, outcomes, complications, and sustainable lifestyle changes of revision surgery performed after laparoscopic sleeve gastrectomy (LSG).
Methods:
This retrospective study included the outcomes of 30 patients who required a revisional surgery from a series of 538 primary LSGs. Demographic data of the patients, indications for revision surgery, complications, postoperative outcomes, and changes in lifestyle were recorded. Postoperative outcomes were analyzed over five periods.
Results:
In total, 18/30 patients (60.0%) underwent revision surgery for weight gain. Of the revision procedures, 53.3% were one anastomosis gastric bypass (OAGB), 33.3% were revisional sleeve gastrectomy (R-SG), and 13.3% were biliopancreatic diversion (BPD). Weight loss in patients after primary surgery was higher than the weight loss after revision surgery. However, while 43.20% of the total weight loss after primary surgery was recovered, only 23.54% was recovered after revision surgery. Except for obstructive sleep apnea syndrome, improvement in comorbidities was similar in primary surgery and revision surgery.
Conclusions:
Although revision surgery achieves lower weight loss than primary surgery, revision surgery is more successful in maintaining weight over time, and it has a limited effect on comorbidities.
