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.

[Complications and level of satisfaction after dermolipectomy and abdominoplasty post-bariatric surgery].

Background: Body contouring surgery is in high demand following the increase in bariatric surgery. But these types of procedures are associated with high complication rates that cause long hospital stays and have a negative effect on patient satisfaction. The purpose of this study is to identify predictors of complications in order to optimize outcomes in these patients and find a relationship between complication rate and satisfaction.

[The labyrinth of composite prostheses in ventral hernias].

Reinforcement or replacement are increasingly being used in the repair of incisional hernias. In many occasions it is necessary to place the prosthesis in the intraperitoneal plane, for which the so called "composite" or bilaminar prostheses have been designed. A terminological precision is made in this article, defending the denomination of dual or "composite" prosthesis for these materials, and the different commercial available options at present are related.

Evaluation of the clinical pathway for laparoscopic bariatric surgery.

Background: Clinical pathways (CP) are comprehensive systematized patient care plans for specific procedures. The CP for morbid obesity was implemented in our department in September 2005. The aim of this study is to evaluate the clinical pathway for this procedure 1 year after implementation.

[Gastric rupture and massive pneumoperitoneum after cardiopulmonary resuscitation by lay persons].

Iatrogenic gastric rupture is a rarely reported complication of cardiopulmonary resuscitation. Rupture can occur during chest compressions or imperfect ventilation. We present the case of 1 patient with a tension pneumoperitoneum after cardiopulmonary resuscitation by lay persons.

Obturator hernia as a cause of chronic pain after inguinal hernioplasty: elective management using tomography and ambulatory total extraperitoneal laparoscopy.

Obturator hernia is a rare variety of pelvic hernia. Preoperative diagnosis is still uncommon and influences treatment and prognosis. Clinical suspicion and tomography are fundamental for establishing a preoperative diagnosis.

[Traumatic Spigelian hernia. Elective extraperitoneal laparoscopic repair].

Traumatic Spigelian hernia is rare. These hernias are usually treated in the same admission through open surgery. We present a case of Spigelian hernia in a high anatomical location following injury, with a cutaneous lesion and preperitoneal hematoma.

[Gastrointestinal stromal tumors. Diagnosis, prognosis and current surgical treatment. Follow-up of 18 treated patients].

Introduction: Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal tumors of the digestive tract and their growth is directed through the signaling of the KIT or PDFGRA genes. The objective of the present study was to describe a series of cases of GIST tumors located in the stomach.

Patients And Methods: We performed a retrospective, descriptive study of 18 patients diagnosed with gastric GIST and treated by means of gastric resection between July 1996 and June 2004.

Anatomical and surgical study of totally extraperitoneal laparoscopic hernioplasty.

Background: Laparoscopic surgery provides direct access to the extraperitoneal inguinal space for a clear, amplified view of the anatomical structures. However, the variety of terms used to describe the fascial elements has partly prevented the promulgation of this approach.

Material/methods: Two hundred patients received surgery for inguinal hernia at an outpatient surgery unit by means of totally extraperitoneal laparoscopy.

Randomized clinical trial of fixation vs nonfixation of mesh in total extraperitoneal inguinal hernioplasty.

Hypothesis: Mesh fixation in the extraperitoneal space during endoscopic total extraperitoneal inguinal hernioplasty might be related to an increase in postoperative pain, morbidity rate, and hospital costs.

Design: Randomized clinical trial.

Setting: University teaching hospital.
