Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass: Is Intrathoracic Migration of the Sleeve of High Incidence?

Background: Conversion of SG to Roux-en-Y gastric bypass (RYGB) is increasing. Intrathoracic migration of the sleeve (ITM) often seems associated and is increasingly reported.

Material And Methods: Patients who underwent a conversion of SG to RYGB from August 2013 to December 2022 were included.

Time impact on the antidiabetic effects of key bariatric surgeries: a network meta-analysis of randomized controlled trials with meta-regression.

Background: Few studies compare the efficacy of the key bariatric procedures in type 2 diabetes management over the long term. None offer a reliable comparison of their respective efficacy loss over time.

Objectives: To analyze and compare the time evolution of the antidiabetic effects of the key bariatric procedures.

Revision of Mason's procedure (vertical banded gastroplasty) to Roux-en-Y gastric bypass: role of an associated fundectomy in weight loss outcomes.

Background: Vertical banded gastroplasty (VBG) presents a significant rate of long-term complications, and revisions are often necessary. Conversion to Roux-en-Y gastric bypass (RYGB) seems to be preferred, but literature data remain limited.

Objectives: To analyze the indications, safety, results of conversions from VBG to RYGB, and to identify predictive factors of success or failure.
