Clinical and pathological features of gastrointestinal stromal tumors (GIST) in a single institution: A descriptive study and review of the literature.

Introduction: This study was aimed to assess the main clinical, pathological and therapeutic characteristics of a cohort of gastrointestinal stromal tumors (GIST).

Methods: Observational study including 66 patients diagnosed with GIST admitted to our hospital between 2002 and 2015. Parameters related to medical history, clinical manifestations, medical and surgical treatment, histopathology, and morbi-mortality were studied.

Perioperative complications following bariatric surgery according to the clavien-dindo classification. Score validation, literature review and results in a single-centre series.

Background: There is no unified system for reporting surgical complications after bariatric surgery. One increasingly used system for notifying postoperative complications is the Clavien-Dindo classification, which focuses on their therapeutic implications.

Objective: The aim of this study is to validate and apply the Clavien-Dindo scale to a series of cases of bariatric surgery and systematically review its use worldwide.

Failure of the Obesity Surgery Mortality Risk Score (OS-MRS) to Predict Postoperative Complications After Bariatric Surgery. A Single-Center Series and Systematic Review.

Background: The obesity surgery mortality risk score (OS-MRS) was developed to determine the risk of postoperative mortality in patients undergoing bariatric surgery. The aim of the present study is to assess the utility of this score for preventing the risk of postoperative complications from bariatric surgery.

Methods: Prospective study of 321 patients undergoing bariatric surgery to whom the OS-MRS was applied.

Emergency endoscopy for gastrointestinal bleeding after bariatric surgery. Therapeutic algorithm.

Objective: Gastrointestinal bleeding (GB) is a potential complication after bariatric surgery and its frequency is around 2-4% according to the literature. The aim of this study is to present our experience with GB after bariatric surgery, its presentation and possible treatment options by means of an algorithm.

Patients And Method: From January 2004 to December 2012, we performed 300 consecutive laparoscopic bariatric surgeries.

Gastrojejunal anastomotic stenosis after laparoscopic gastric bypass. Experience in 280 cases in 8 years.

Objective: Gastrojejunal stricture (GYS), not only is a common complication after laparoscopic gastric bypass, but its frequency is about 15% according to bibliography. Our aim is to present our experience after 280 laparoscopic gastric bypass.

Patients And Method: From January 2004 to December 2012, 280 patients underwent a laparoscopic Roux en Y gastric bypass with creation of the gastrojejunal anastomosis is performed with circular stapler type CEAA No 21 in 265 patients and with a linear stapler in 15 patients.
