Image findings in celiac artery stenosis due to median arcuate ligament compression: a crucial diagnosis when planning for pancreaticoduodenectomy.

Celiac axis stenosis caused by extrinsic compression by the median arcuate ligament (MAL) is present in up to 5% of patients undergoing pancreaticoduodenectomy. Failure to identify and manage MAL compression can lead to potentially devastating postoperative consequences that include frank liver necrosis and death. We report an incidental discovery of celiac axis stenosis by MAL in a patient prepared for pancreaticoduodenectomy.

Assessment of neoadjuvant chemotherapy on operative parameters and outcome in patients with peritoneal dissemination from high-grade appendiceal cancer.

Background: High-grade appendiceal adenocarcinoma is a rare malignancy with propensity for peritoneal metastases (PM). The impact of neoadjuvant chemotherapy on operative cytoreduction (CRS) and intraperitoneal chemotherapy (HIPEC) and patient survival was reviewed.

Methods: A total of 45 patients with PM from high-grade appendiceal adenocarcinoma were identified from a prospective database.

Surgery for peritoneal mesothelioma.

Malignant peritoneal mesothelioma (MPM) is a rare, progressive, and ultimately fatal disease in almost all afflicted individuals. MPM is a cancer that arises diffusely from the serosa of the abdominal cavity and progresses almost exclusively in this region; understanding its characteristic tumor biology has been the reasoning behind the development of treatment strategies designed to control disease progression in the peritoneum. This principally includes operative cytoreduction and hyperthermic intra-operative perfusion of intraperitoneal chemotherapy (HIPEC).
