Complications Following the Mini/One Anastomosis Gastric Bypass (MGB/OAGB): a Multi-institutional Survey on 2678 Patients with a Mid-term (5 Years) Follow-up.

Background: In recent years, several articles have reported considerable results with the Mini/One Anastomosis Gastric Bypass (MGB/OAGB) in terms of both weight loss and resolution of comorbidities. Despite those positive reports, some controversies still limit the widespread acceptance of this procedure. Therefore, a multicenter retrospective study, with the aim to investigate complications following this procedure, has been designed.

What was the survival of megaprostheses in lower limb reconstructions after tumor resections?

Background: Prosthetic replacement is the most commonly used option for reconstruction of osteoarticular bone loss resulting from bone neoplasm resection or prosthetic failure. Starting in late 2001, we began exclusively using a single system for large-segment osteoarticular reconstruction after tumor resection; to our knowledge, there are no published series from one center evaluating the use of this implant.

Questions/purposes: We investigated the following issues: (1) What is the overall survival, excluding local tumor recurrence, for these endoprostheses used for tumor reconstructions of the lower extremities (knee and hip)? (2) What types of failure were observed in these reconstructions? (3) Do the survival and complications vary according to site of implant?

Methods: Between September 2001 and March 2012, we exclusively used this implant for tumor reconstructions.

Preoperative prediction of growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis modification and postoperative changes in candidates for bariatric surgery.

Background: Several factors alter the growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis in obese patients, but GH/IGF-1 correlation with anthropometric parameters and lipid metabolism is still unclear. We evaluated this relationship and the postoperative axis modifications in candidates for bariatric surgery.

Methods: Eighty-eight patients (males/females (M/F), 34/54) scheduled for bariatric surgery (biliopancreatic diversion or laparoscopic-adjustable gastric banding) between 2008 and 2010 were included in this observational, open, prospective study.

Long-term results of biliopancreatic diversion with or without gastric preservation for morbid obesity.

We aimed at comparing our long-term results after biliopancreatic diversion (BPD) with or without gastric preservation for morbid obesity. Between 1999 and 2009, we performed 540 BPD: 287 patients (group A) underwent BPD with distal gastric resection (BPD-AHS) and 253 (group B) underwent BPD associated with transitory vertical gastroplasty (TGR) with duodenal switch (DS). The results have been analyzed in terms of weight loss, improvement of comorbidities, and quality of life (Bariatric Analysis and Reporting Outcome System).
