Laparoscopic resection of gastric schwannoma: A case report.

Introduction: Gastric schwannomas are an extremely rare presentation of mesenchymal tumors originating from Schwann cells, accounting for 0.2% of all gastric tumors. Patients are usually asymptomatic, so these tumors are frequently detected incidentally.

Gastric perforation and subarachnoid hemorrhage secondary to intragastric balloon device.

Obesity is a major health problem worldwide that leads to high morbidity and mortality rates. Medical options for obesity treatment are multiple and invasive therapy may be classified as surgical and non-surgical. Intragastric balloon device placement is an invasive non-surgical option that may benefit some obese patients.

Ileocolic intussusception secondary to Hodgkin's lymphoma. Report of a case.

Intussusception is a rare condition in adults and represents 1% to 5% of the total cases of intestinal obstruction. Preoperative diagnosis occurs only in a few patients and most of the cases are diagnosed during surgery. A demonstrable etiology is found in 70% to 90% of cases in adult intussusceptions, and approximately 40% of them are caused by primary or secondary malignant tumors.

[Laparoscopic therapy of gastric volvulus associated with hiatal hernia in the elderly patient].

Gastric volvulus is an abnormal rotation of one portion of the stomach around itself that may lead to gastric obstruction or an impairment of the vascular supply to the stomach leading to strangulation. This may present acutely or with chronic intermittent symptoms. Acute gastric volvulus is an emergency situation in which there is a closed loop obstruction and vascular compromise that requires urgent treatment.

Acute epiploic appendagitis. Report of three cases.

Primary epiploic appendagitis is a very rare condition that results from acute inflammation of an epiploic appendix. Clinical presentation is non-specific, and many times can mimic acute abdomen. When the diagnosis of epiploic appendagitis is made, conservative treatment must be initiated to avoid unnecessary surgery.
