Transit Bipartition to Promote Weight Loss After Laparoscopic Sleeve Gastrectomy

Prospective data base of 100 consecutive morbidly obese patients who had undergone transit bipartition (TB, also termed "Single Anastomosis Sleeve Ileal bypass") after a previous sleeve gastrectomy (LSG). Inclusion criteria were TB for excess weight loss (EWL) < 50% ≥ 12 months post LSG or weight recidivism of > 5 kg/qm with a body mass index (BMI) > 30 kg/qm. Patients with endocrine disorders other than type 2 diabetes mellitus (T2D), major psychiatric disorders, American Society of Anesthesiologists (ASA) III and higher or pregnant patients were excluded from the study. Data were prospectively collected in strictly pseudonymous form. Follow up time points were at 1, 3, 6 and 12 months following TB. The primary endpoint of the study is weight loss at 1, 3, 6 and 12 months after TB. A subgroup analysis evaluates the effect of the length of the common channel. Secondary endpoints include impact on obesity related comorbidities such as T2D, hypertension, sleep apnea, gastroesophageal reflux as well as safety.
