Mid-term outcomes after single anastomosis sleeve ileal (SASI) bypass in treatment of morbid obesity.

Background: According to several short-term studies, single-anastomosis sleeve ileal (SASI) bypass offers similar weight loss to Roux-en-Y Gastric Bypass (RYGB) with fewer complication and better comorbidity reduction/resolution. Long-term data on this operation is lacking in the literature. The purpose of this study was to analyze the outcomes of SASI bypass up to 4 years.

Gastric bypass with long alimentary limb or long pancreato-biliary limb--long-term results on weight loss, resolution of co-morbidities and metabolic parameters.

Background: Several studies indicate that increasing the alimentary limb length in gastric bypass surgery produces only a minor improvement of excess BMI loss. Few studies have addressed the efficacy of increasing the length of the pancreatico-biliary limb.

Methods: Here, we present a prospective randomized study of 187 consecutive laparoscopic Roux-Y gastric bypass operations operated over 2 years (2004-2005) in Iceland.

Internal hernia after gastric bypass: a new and simplified technique for laparoscopic primary closure of the mesenteric defects.

Background: Bowel obstruction due to internal hernia is a well-known complication of laparoscopic Roux-en-Y gastric bypass (LRGB). Increasing evidence supports primary closing of the mesenteric defects, but controversy continues about surgical technique of systematic closure. This paper reviews our experience with internal hernia after LRGB and describes a new method of preemptive closure of the mesenteric defects.
