Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

Gastrointestinal stromal tumors (GISTs) rarely arise in the rectum. Whereas a local resection with negative margins is generally considered adequate for resectable GISTs, a wide resection is usually indicated for rectal lesions because of the technical impossibility of local resection. We report the cases of two patients who underwent resection of a rectal GIST using a transsacral approach. Both patients had an uneventful postoperative course, and no evidence of recurrence has been identified. The transsacral approach appears to be less invasive and should be considered as the treatment of choice for a rectal GIST.

Gastric volvulus is an uncommon entity that may rapidly progress to infarction and necrosis of the stomach. We herein report the case of a 67-year-old man with acute gastric volvulus in association with wandering spleen. Following a reduction of the volvulus with a nasogastric tube, laparoscopic gastropexy was performed. Pediatric cases of gastric volvulus and a concurrent wandering spleen have been described, but to the best of our knowledge, no adult cases have previously been reported.
