Possible technical aspects involved in the development of GERD after sleeve gastrectomy: Surgical technique considerations.

Sleeve gastrectomy (SG) is the most common bariatric surgery worldwide and has shown to cause de novo or worsen symptoms of gastroesophageal reflux disease (GERD). Esophageal motility and physiology studies are mandatory in bariatric and foregut centers. The predisposing factors in post-SG patients are disruption of His angle, resection of gastric fold and gastric fundus, increased gastric pressure, resection of the gastric antrum, cutting of the sling fibers and pyloric spasm.

Laparoscopic splenectomy and proximal splenorenal shunt for portal hypertension due to portal vein thrombosis in a patient with protein S deficiency.

Portal vein thrombosis (PVT) is a rare condition in the general population that develops serious complications if left untreated for long time. We present a case of a 29-year-old woman who developed PVT due to protein S deficiency versus neonatal funiculitis. Over time, the patient developed upper gastrointestinal bleeding due to esophageal varices and hypersplenism with splenic sequestration that caused minor bleeding episodes.

[Idiopathic cecal ulcer: report of a case].

The idiopathic cecal ulcer is rare in frequency, there are case reports and small series in the literature but in Peru have not been described yet. They are of unknown etiology and wide differential diagnosis, we report the case of a medical intern with lower gastrointestinal bleeding history and a solitary cecal ulcer that was suspected of being cancer, then an emergency laparoscopic right hemicolectomy was performed, after an extensive study we conclude that it is an idiopathic cecal ulcer.

[Hepatic angiosarcoma: case report and review of literature].

Hepatic Angiosarcoma is an uncommon neoplasia with an incidence between 0.5 to 2 % of primary hepatic tumors. Due to a nonspecific presentation it is very difficult to reach the diagnosis which is usually late and by that time the organ has been involved by tumor and surgical treatment is not possible.
