- Abstract
Revisional bariatric surgery following laparoscopic sleeve gastrectomy (LSG) failure presents a clinical challenge for the bariatric surgeon. Limited evidence exists in selecting the appropriate revisional operation: laparoscopic gastric bypass (LGB), laparoscopic re-sleeve gastrectomy (LRSG), or other surgical intervention (OSI), to address weight regain. We systematically reviewed the literature to assess the efficacy of existing revisional surgery. A comprehensive search of electronic databases (e.g., Medline, Embase, Scopus, Web of Science, and the Cochrane Library) was completed. All randomized controlled trials, non-randomized comparison study, and case series were included. Eleven primary studies (218 patients) were identified and included in the systematic review. Studies were grouped into three main categories: LGB, LRSG, and OSI. Preoperative body mass index (BMI) was 41.9 kg/m (LGB), 38.5 kg/m (LRSG), and 44.4 kg/m (OSI). After conversion to LGB, BMI decreased to 33.7 and 35.7 kg/m at 12 and 24 months of follow-up, respectively. Excess weight loss (EWL) was 60 and 48 % over the same periods. After LRSG, BMI decreased to 30.4 and 35.3 kg/m with corresponding EWL of 68 and 44 %, at 12 and 24 months, respectively. After OSI, BMI decreased to 27.3 kg/m with an EWL of 75 % at 24-month follow-up but could not be analyzed due to incomplete data collection in primary studies. Both LGB and LRSG achieve effective weight loss following failed LSG. The less technically challenging nature of LRSG may be more widely applicable. Further research is required to elicit sustainability in long-term weight loss benefits.
