Bio-Thiersch as an Adjunct to Perineal Proctectomy Reduces Rates of Recurrent Rectal Prolapse.

Background: The rates of recurrent prolapse after perineal proctectomy vary widely in the literature, with incidences ranging between 0% and 50%. The Thiersch procedure, first described in 1891 for the treatment of rectal prolapse, involves encircling the anus with a foreign material with the goal of confining the prolapsing rectum above the anus. The Bio-Thiersch procedure uses biological mesh for anal encirclement and can be used as an adjunct to perineal proctectomy for rectal prolapse to reduce recurrence.

Palliative Resection of a Giant Mesenteric Desmoid Tumor.

Background: Desmoid tumors are relatively uncommon tumors, and those occurring sporadically and in an intraabdominal location are especially rare. Although desmoid tumors have a benign histologic appearance and lack the ability to metastasize, they can invade locally, often aggressively, grow to large sizes, and recur repeatedly.

Case Report: We present the case of a symptomatic, giant mesenteric desmoid tumor discovered incidentally during workup for the patient's previous history of lung cancer.
