Thirty days post-operative complications after Sleeve Gastrectomy, Gastric Bypass and Mini Gastric Bypass/one Anastomosis Gastric Bypass. Analysis of the Italian Society for Bariatric Surgery and Metabolic Disorders (S.I.C.OB.) database of 7 years time frame

Background: To date, the scientific community has
mainly focused on outcomes of obesity surgery such as weight loss and
resolution of associated complications. Adverse post-operative events
and reoperation rates have been poorly reported even if they are a
marker of surgical safety and therefore of great importance in guiding
patients and surgeons in the choice of the more suitable operation.

Methods: This retrospective multicenter observational study is
based on the data extracted from the Italian Society of Bariatric
Surgery and Metabolic Disorders (S.I.C.OB.) database, which covers
almost all the bariatric operations performed in Italy. We analysed the
30 days post-operative complications occurring, in the period from 2009
to 2015, after Roux-en-Y Gastric Bypass (RYGB), Sleeve Gastrectomy (SG)
and Mini Gastric Bypass/One Anastomosis Gastric Bypass (MGB/OAGB)
qualitatively, quantitatively and on the basis of the Clavien-Dindo
classification of surgical complications. Complications following
surgeries were tested using the 95% confidence interval. Statistical
analysis was performed with Statistical Analysis System (SAS).
