Gastropleural fistula (GPF) is a rare, life-threatening complication of gastric sleeve surgery. GPF is an uncommon differential diagnosis to consider in a patient presenting with a picture of pneumonia. As such, GPF should be suspected in a patient with a history of nonresolving pneumonia who recently underwent gastric sleeve surgery. To the best of our knowledge, only eight cases of gastropleural fistulas after bariatric surgery have been reported in the literature. Herein, we report a case of gastropleural fistula after gastric sleeve surgery and review the pertinent literature. A gastropleural fistula is an exceedingly rare and life-threatening complication postbariatric surgery. Nonsurgical conservative management (total parenteral nutrition, percutaneous drainage, and antibiotics with endoscopic stenting) can be considered.

The retroperitoneum is the abdominal portion located behind the sac of the peritoneal cavity and extending from the diaphragm to the pelvic inlet. A Retroperitoneal hematoma is a rare but a fearsome complication after appendectomy. The management of retroperitoneal hematomas can be difficult as the decision between a surgical intervention, angiographic embolization, and conservative management with fluids can be difficult to make. This case report would be outlining the clinical presentation, radiological findings, and outcome of a 60-year-old male who has been diagnosed with an intra-abdominal, retroperitoneal hematoma and flank ecchymosis with no signs of active bleeding after laparoscopic appendectomy. Retroperitoneal hematomas can be extensive post-laparoscopic abdominal surgeries. A comprehensive physical examination, radiological imaging, and laboratory investigations should be considered to rule out the possibilities of bleeding disorders and/or active bleeding contributing to the development of retroperitoneal hematomas.
