Multicenter StudySingle stage conversion from adjustable gastric banding to sleeve gastrectomy or Roux-en-Y gastric bypass: an analysis of 4875 patients.
The previous popularity of adjustable gastric banding (AGB), along with inconsistent long-term results, has resulted in the need for conversion to other procedures. The perioperative safety of laparoscopic sleeve gastrectomy (SG) and gastric bypass (RYGB) as single-stage conversion procedures is unclear. ⋯ AGB conversions are associated with low overall 30-day event rates. Patients undergoing RYGB as a single-stage conversion experience higher complication rates and the need for additional early procedures compared with SG.

Multicenter StudyFactor VIII elevation may contribute to portomesenteric vein thrombosis after laparoscopic sleeve gastrectomy: a multicenter review of 40 patients.
Portomesenteric vein thrombosis (PMVT) has been increasingly reported after laparoscopic sleeve gastrectomy (LSG). Factor VIII (FVIII) is a plasma sialoglycoprotein that plays an essential role in hemostasis. There is increasing evidence that FVIII elevation constitutes a clinically important risk factor for venous thrombosis. ⋯ A high index of clinical suspicion and prompt diagnosis/treatment of PMVT usually leads to favorable outcomes. FVIII elevation was the most common (76%) hematologic abnormality identified in this patient cohort. Further studies are needed to determine the prevalence of FVIII elevation in patients seeking bariatric surgery.
