Laparoscopic parastomal hernia repair.

BACKGROUND: Management of the parastomal hernia represents a common clinical dilemma for both the surgeon and patient. Once established, these defects are notoriously difficult to treat. Although most parastomal hernias can be managed nonoperatively, approximately 30% will require intervention secondary to complications such as obstruction, pain, bleeding, poorly fitting appliances, or leakage. Overall complication rates of up to 88%, combined with a growing body of literature citing decreased patient morbidity and improved outcomes with laparoscopic tension-free mesh repair of ventral hernias, have led many surgeons to apply these techniques to this difficult problem. METHODS: This was a retrospective review of 21 consecutive patients who underwent laparoscopic repair of their parastomal hernias with ePTFE mesh. RESULTS: Nine (43%) were ileal conduits, seven (33%) were ileostomies, and five (24%) were colostomies. Eight patients had undergone prior hernia repair. Follow-up ranges from 1 to 36 months (average 14 months). There has been one recurrence (5%). Other complications included laparoscopic re-operation for obstruction of a urinary conduit (n=1), mesh removal for infection (n=2), Clostridium Difficile colitis (n=1), pneumonia (n=2), renal failure (n=1), surgical site infection (n=1), and bowel obstruction at a site remote from the hernia repair (n=2). CONCLUSION: The laparoscopic approach to parastomal hernias is a new technique that offers many potential advantages over conventional open repairs. Based on our initial experience, this repair seems to be associated with a low recurrence rate.

Myofibrosarcoma of the adrenal gland.

Adrenal masses have varying presentations. Most commonly, adrenal masses are discovered incidentally on CT or MRI during an evaluation for an unrelated complaint. Although the majority of these are nonfunctional cortical adenomas, hormonally active tumors and adrenocortical carcinoma must also be considered in the differential diagnosis. Rarely, retroperitoneal tumors may mimic an adrenal mass. We report a case of a 49-year-old man with anemia and weight loss who was found to have a large retroperitoneal mass arising from the adrenal gland. Surgical treatment involved en bloc resection of the right kidney, adrenal gland, segments 7 and 8 of the liver, and a portion of the right hemidiaphragm. Final pathology revealed a low-grade myofibrosarcoma. We believe that this is the first case report of a myofibrosarcoma of the adrenal gland. Myofibrosarcomas are rare malignant tumors composed of myofibroblasts that arise from the deep soft tissues. These tumors have a predilection for the head and neck, trunk, or extremities. Myofibrosarcomas can be differentiated from other sarcomas by immunohistochemical staining and pathologic features. We will briefly discuss the workup of an adrenal mass and focus on the diagnosis of myofibrosarcoma.
