Abstract

Of the 103,782 primary sleeve gastrectomy procedures, 7,181 (6.9%) were converted to other operations.

The majority of conversions (86.2%) were to Roux-en-Y gastric bypass.
Gastroesophageal reflux disease (GERD) was the leading reason for conversion at 48.4%.
Weight regain or insufficient weight loss accounted for 41.9% of conversions.
Patients undergoing biliopancreatic diversion with duodenal switch and single-anastomosis duodenoileal bypass showed significant differences in preoperative characteristics and outcomes compared to those converted to Roux-en-Y gastric bypass.

BACKGROUND: Although the sleeve gastrectomy (SG) is the dominant bariatric procedure, studies have shown conversion rates of up to 30%. These conversions are generally for weight regain (WR), insufficient weight loss (IWL) or gastroesophageal reflux disease (GERD). Before 2020, details on why conversions were being performed were not collected in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Participant Use Data File (PUF). Now, the indication for sleeve conversion is noted in the PUF, allowing identification and reporting sleeve conversion reasons.

OBJECTIVE: We aimed to examine the reasons for SG conversions nationwide.

SETTING: The 2020 MBSAQIP PUF.

METHODS: The 2020 MBSAQIP PUF was examined to determine the reasons why SG were converted to other operations. The data field of "Revision/Conversion Final Indication" was used along with "Procedure type." Primary bariatric operations were excluded. Descriptive statistics were applied. Different reasons for conversion and operations were compared by preoperative characteristics and operative outcomes.

RESULTS: There were 103,782 primary SG reported in the 2020 PUF. There were 7181 SG that were converted to other operations. The most common conversion (86.2%) was to Roux-en-Y gastric bypass (RYGB). The main reason for SG conversion was GERD at 48.4%, followed by WR/IWL (41.9%). Biliopancreatic diversion with duodenal switch and single-anastomosis duodenoileal bypass with sleeve patients differed significantly from RYGB patients in specific preoperative characteristics and operative outcomes.

CONCLUSION: The most common procedure SG is converted to is the RYGB. GERD was the most common reason for SG conversion, followed by WR/IWL.
