Recurrence of fusocellular subtype GIST with SDHB mutation: A case of SDHB-loss and therapeutic challenges.

Gastrointestinal stromal tumors (GISTs) are sarcomas affecting the stomach and small intestine, with a rare subtype characterized by succinate dehydrogenase B (SDHB)-loss posing significant diagnostic and therapeutic challenges. A 62-year-old man with weight loss and abdominal pain was diagnosed with a gastric GIST showing SDHB-loss. Initial treatment with Imatinib reduced the tumor size, but surgery revealed no residual tumor.

DEPRESSIVE AND EATING DISORDERS IN PATIENTS POST-BARIATRIC SURGERY WITH WEIGHT REGAIN: A DESCRIPTIVE OBSERVATIONAL STUDY.

Background: Although bariatric surgery is today's gold standard treatment for obesity, weight regain affects the success rate of the procedure. Recent studies have identified psychiatric and neurological factors as possible causes.

Aims: The aim of this study was to evaluate the influence of psychiatric diseases on the outcome and long-term success of bariatric surgeries and find a weight regain threshold that has an acceptable sensibility to mental health-related issues to be used in research and clinical studies.

Perforated gastric ulcer post mini gastric bypass treated by laparoscopy: A case report.

Introduction: Among the many techniques available for bariatric surgery, the Mini Gastric Bypass is a safe, technically simple and effective option. However, it may present with postoperative complications, being the perforated gastric ulcer one of the most relevant ones.

Presentation Of Case: A female patient of 41 years of age, with past medical history of a laparoscopic MGB performed 2 year before, presented with 12 hours of sharp and abruptly initiated abdominal pain, with diffuse presentation with suspected perforated acute abdomen after initial medical assessment and examination.

Treatment of De Garengeot's hernia using De Oliveira's technic: A case report and review of literature.

Introduction: The French surgeon Rene Jacques Croissant de Garengeot first described the finding of the Appendix inside a femoral hernia sac in 1731. The De Garengeot's hernia is a rare entity, comprehending only 0.5-5% of the femoral hernias.

Treatment of abdominal wall hernia with suture, or polypropylene, or collagen prosthesis.

Purpose: To develop an experimental model for incisional hernias and to compare morphological and functional aspects of hernia repairs by suture, polypropylene mesh and collagen mesh.

Methods: A defect measuring 7cm x 2cm was created in the anterior abdominal of 28 New Zealand male rabbits, divided into four groups (n = 7): (1) control, (2) suture of the anterior sheath of the rectus abdominal muscle, (3) setting of polypropylene mesh, and (4) setting of collagen mesh. On the 90th postoperative day, the animals were examined to verify the presence of incisional hernia.

Cardiac tamponade as a complication of parenteral nutrition.

Introduction: Complications arising from the use of central venous catheters are numerous, but cardiac tamponade is a complication well defined, very rare and often fatal. The mortality rate is 47-77% in the literature.

Presentation Of Case: We report a case of successful diagnosis and treatment of cardiac tamponade by parenteral nutrition in a 31-year-old female.
