Solitary necrotic nodule of the liver: different pathological findings express a different histogenesis.

Solitary necrotic nodule of the liver is a rare benign lesion the histogenesis of which is still debated. We here report the case of a patient who underwent laparoscopic cholecystectomy for gallstones and who was accidentally found to have a solitary necrotic nodule of 2 cm in the fifth segment of the liver. On the basis of the histological findings, the hypothesis that different pathogenetic mechanisms could be involved in the histogenesis of this lesion is discussed.

Long-term manometric study of anal sphincter function after hemorrhoidectomy.

Background And Aim: Data on maximum resting pressure (MRP) and maximum squeeze pressure (MSP) changes after hemorrhoidectomy are not univocal and follow-up of patients undergoing surgery is mostly short-lived. The aim of this study was to prospectively examine during 1-year follow-up the long-term manometric results of MRP, MSP, and ultra slow wave activity (USWA) within a set of patients undergoing Milligan-Morgan hemorrhoidectomy as compared to healthy controls.

Materials And Methods: Twenty patients with hemorrhoids of third and fourth degree were enrolled and anorectal manometry was performed preoperatively, on the 5th day, and after 1, 6, and 12 months after surgery.
