Spontaneous pneumoperitoneum in the absence of visceral perforation in a patient with systemic sclerosis: a case report.

We present the case of a 44 year old woman with systemic sclerosis who presented with intense abdominal pain without signs of peritonitis. An abdominal computed tomography showed generalized intestinal dilation, intestinal pneumatosis and an extensive pneumoperitoneum. A diagnostic laparoscopy was performed but no perforation nor gastrointestinal leakage were found.

Intestinal intussusception as a postoperative complication of gastric bypass.

The gold standard for bariatric surgery is the laparoscopic gastric bypass, which consists in forming a small gastric pouch and a Roux-en-Y anastomosis. We present the case of a 41-year-old female who underwent a laparoscopic gastric bypass 8 years prior to her admission to the emergency room, where she arrived complaining of severe and colicky epigastric abdominal pain. The abdominal computed tomography showed a jejuno-jejunal intussusception, for which the patient underwent urgent exploratory laparotomy with intussusception reduction.

Ruptura esplénica después de terapia anticoagulante en un paciente con antecedente de COVID-19: reporte de caso.

We present the case of a 75-year-old man with a history of COVID-19 and splenic infarct treated with enoxaparin, who presented with intense abdominal pain and tomographic findings of free peri-splenic fluid and a hyperdense image in the spleen. An emergency laparotomy was performed, with findings of a splenic rupture at the vascular hilum. Spontaneous splenic rupture is a rare and fatal entity that should be suspected in a patient with history of COVID-19 who presents with acute abdominal pain after the administration of heparin.
