Outcomes of reoperative surgery in severely obese patients after sleeve gastrectomy: a single-institution experience

Zusammenfassung: | Despite its popularity, sleeve gastrectomy (SG) is not devoid of postoperative complications and weight regain. Some of these cases warrant conversion to Roux-en-Y gastric bypass or proximal gastrectomy with Roux-en-Y esophagojejunostomy. Complications after conversion are scarcely reported in the literature.
Report and review the outcomes of reoperation on severely obese patients with weight regain or complications after SG.
Bariatric Surgery Center of Excellence; Community Hospital, United States.
We retrospectively reviewed the medical records of patients converted from SG to Roux-en-Y gastric bypass/proximal gastrectomy with Roux-en-Y esophagojejunostomy at our center, from 2004 to 2018. Patients were stratified by reason for conversion. Group A included those converted for complications (leaks, strictures, or gastroesophageal reflux disease) and group B for reported weight regain. Demographic characteristics, postoperative outcomes, and complications were described.
From 77 conversions identified, 63.6% (n = 49) underwent primary SG at an outside hospital. We observed predominant female (68.8%; n = 53) and Caucasian (76.6%; n = 59) populations. Conversions for complications were performed in 67.5% (n = 52) and for weight regain in 32.4% (n = 25). The most common conversion indication in group A was chronic leak (29.9%; n = 23), followed by gastroesophageal reflux disease (20.8%; n = 16), and stricture (16.9%; n = 13). Overall, major complications occurred in 16.9% (n = 13) and minor complications in 19.4% (n = 15). In group A, most common major complications were anastomotic leak and organ space surgical site infection (3.9%; n = 2 each); the most common minor complication was nonperforated marginal ulcer (7.7%; n = 4). In group B, the most common major complication was perforated marginal ulcer (8%; n = 2); the most common minor complication was stricture (16%; n = 4). Group B mean preconversion body mass index was 38.4 ± 4.3 and percentage excess body mass index loss was 48 ± 33, 63 ± 45, 59 ± 63, and 73 ± 25 (12, 24, 36, ≥48 mo).
Our experience shows that major complications can occur in up to 17% of patients after conversion. Conversion to Roux-en-Y gastric bypass in nonresponders appears to be a safe and effective option for body mass index reduction. |
