Advantages of the Maneuver of Intestinal Derotation for Pancreaticoduodenectomy.

Background And Aims: Pancreaticoduodenectomy (PD) is the surgical treatment of choice for cephalopancreatic cancer representing the only hope of cure. Since its first description in 1935 by Allan Whipple, several modifications have been proposed. The execution of the Cattell-Braasch maneuver of intestinal derotation (ID) in the course of PD, by restoring the entire bowel to its embryological position, could represent a further and multiexpedient variant.

Surgical management of abdominal manifestations of type 1 neurofibromatosis: experience of a single center.

Neurofibromatosis type 1 (NF1) is a genetic disease characterized by neoplastic and nonneoplastic disorders involving tissues of neuroectodermal and mesenchymal origin. The mainly involved districts are skin, the central nervous system, and eye and there is a wide range of severity of clinical presentations. Abdominal manifestations of NF1 include five kinds of tumors: neurogenic tumors (neurofibromas, malignant peripheral nerve sheath tumors [MPNSTs], and ganglioneuromas); neuroendocrine tumors (pheochromocytomas and carcinoids); nonneurogenic gastrointestinal stromal tumors (GISTs); embryonal tumors; and miscellaneous.
