Biliopancreatic diversion with transitory gastroplasty preserving duodenal bulb: 3 years experience.

Background: The authors have performed 521 bariatric surgery operations (319 restrictive procedures and 202 malabsorptive procedures).

Methods: During the last few years we have introduced an evolution of biliopancreatic diversion (BPD): BPD with transitory gastroplasty, preserving the duodenal bulb (53 cases). From a technical point of view, the operation consists of a BPD, coupled with a gastroplasty which is transitory due to the use of a polydioxanone (PDS) band.

Reflections on Four Years' Activity of an Interdisciplinary Centre for the Treatment of Obese Patients.

Since 1988, there has been an interdisciplinary center for obesity treatment in Stradella's Hospital's Surgery Department,. Patients are followed by a group of surgeons, anesthetists and dietitians, who choose the proper treatment for the patient. The surgical treatments are two: (1) vertical banded gastroplasty; and (2) a new technique consisting of biliopancreatic diversion plus a vertical banded gastroplasty with stomach ad hoc.

Location of central venous catheters in children by endocavitary ECG: A new technique.

A new technique to establish the position of a central venous catheter (CVC) by endocavitary ECGraphy is described. The principle is based on the fact that the catheter itself may be considered as an electrical conductor by means of its liquid content (saline solution), therefore acting as an exploring electrode. The intrinsic deflection of the P wave shows the proper position of the CVC tip at the sinus node level.

[Malignant hyperthermia. The need for anesthesia in a patient manifesting this syndrome].

Successful treatment of malignant hyperthermia, following its prompt recognition in a young patient during general anaesthesia with halothane and succinylcholine, preceded the equally successful employment of ketamin, with no signs of enzyme alteration and circulatory stability, when the same subject had to be operated 20 days later.
