Abstract

Background

After Roux-en-Y gastric bypass (RYGB), up to 30% failures in weight loss have been reported. Among multiple solutions available, we report our experience with shortening of the common channel (SCC) by performing a limb distalization of the alimentary or the biliopancreatic limb.

Settings

University Hospital.

Methods

We reviewed data from 23 patients that underwent limb distalization between 2001 and 2019 due to inadequate weight loss after an initial RYGB in our center. All patients who failed to achieve an excess weight loss reduction of > 50% or maintained a body mass index (BMI) above 35 kg/m2 were included. Multiple variables were analyzed during the follow-up at five time points: initial, after RYGB, before SCC, after SCC, and current.

Results

The mean BMI prior to the RYGB was 51.8 kg/m2, after RYGB was 37.6 kg/m2, before SCC was 43.6 kg/m2, after SCC was 36.1 kg/m2, and the final BMI was 36.3 kg/m2. No morbidity was seen after SCC. Long-term associated nutritional deficiencies were only identified in 3 patients which had iron deficiency and 1 patient with vitamin D deficiency. Patients with associated comorbidities significantly improved or were withdrawn from medications after the RYGB, with minor variations after SCC.

Conclusions

Limb distalization with SCC is a safe and effective technique for patients who failed to achieve an adequate weight loss after RYGB. There is a slight increase in excess of weight loss after the SCC compared with RYGB. In addition, no further weight regain was documented.
