Transit Bipartition with Duodeno-Ileal Anastomosis, without Duodenal Exclusion, as a First Stage of Bariatric Surgery in Severely Obese Patients: Case Report

Obesity is a difficult disease to control; bariatric surgery is one of the tools used to treat obesity and its comorbidities. The present case was chosen because it concerns a very obese patient whose proposed surgery—duodenal switch—resulted in traoperatively difficult to the medical team because the esophagogastric junction could not be reached due to the presence of hepatomegaly. Due to this unfavorable condition, we decided to perform a duodeno-ileal anastomosis with gastric preservation and without duodenal exclusion. The patient has been under follow-up for 14 years. She has lost 55 kg and maintains the comorbidities controlled to date.
