A clinical and nutritional comparison of biliopancreatic diversion performed with different common and alimentary channel lengths.

Background: This retrospective study compares the clinical and nutritional outcomes of 100 morbidly obese patients who underwent biliopancreatic diversion (BPD) with common (CC) and alimentary channel (AC) length, respectively, 50/250 and 80/200 cm.

Methods: One hundred patients who received BPD from October 2006 to November 2011 were identified from a database of bariatric procedures performed at the University Hospital of Messina, and the outcomes in terms of weight loss and morbidity were compared. Forty morbidly obese patients underwent BPD with CC 80 cm and AC 200 cm (group 1) and 60 morbidly obese patients underwent BPD with CC 50 cm and AC 250 cm (group 2).

[Intraoperative ultrasonography in the staging of pancreatic head neoplasms].

Tumours of the head of the pancreas constitute the fourth most common cause of cancer deaths. These tumours are characterised by low survival rates (5% at 5 years) and low surgical resectability rates (20-25%). Liver metastases, lymph-node and vascular involvement, and peritoneal metastases are, in our opinion, exclusion criteria for curative surgical resection.
