Biliopancreatic diversion with transitory gastric restriction and duodenal bulb preservation: 88 patients since 1992.

BACKGROUND: Over 10 years, 88 patients underwent biliopancreatic diversion with transitory gastric restriction (BPD-TGR) as a first choice operation or after gastric restrictive procedures. METHODS: From 1992 to 1999, BPD-TGR was performed on 71 patients as a first choice operation (Group 1 - BMI 41.9 +/- 6.5). The TGR was achieved by a polydioxanone (PDS) band. The duodenal bulb was maintained to 5 cm distal to the pylorus, constructing an end-to-side antecolic isoperistaltic duodeno-ileal anastomosis. Since 1993, a further 17 patients underwent BPD-TGR as a correction for restrictive procedures (Group 2 - BMI 37.4, range 27.2-61.0). RESULTS: Results in weight loss in Group 1 were similar to those in our previous classical BPD. Percent excess weight loss (%EWL) was 68.0 +/- 18.4, 75.9 +/- 12.3, and 75.4 +/- 12.0 at 1,5 and 10 years respectively. No patient had severe dysproteinemia (only 3% of patients had hypoalbuminemia of 3.0-3.4 g/dl). There was no case of diarrhea or halitosis. Anastomotic ulcers occurred in 2% of the patients. In Group 2, the patients had weight loss already present from the first operation, which continued after BPD-TGR with great variability from patient to patient. %EWL was 35.1 (range 0 to 72.5) and 35.2 (range 18.4 to 43.2) at 1 and 5 years. CONCLUSIONS: BPD-TGR appears to be an effective operation with few complications and also a satisfactory correction for failed gastric restrictive procedures, or even a sequential operation in the super-obese.

[Tourniquet pain: anatomic-physiological notes and clinical aspects].

OBJECTIVES: The mechanism of tourniquet pain is quite complex. This paper, supported by the previous literature on this topic, tries to explain why the anaesthetic blockade of a limb, even when thechnically successful, not always prevents the occurrence of this pain. DATA SOURCES: Papers published between 1990 and 1995, listed on Index Medicus, with pertinent references. STUDY SELECTION: Reports dealing with physiological basis of tourniquet pain. CONCLUSIONS: Tourniquet pain is nociceptive, generated not only by activation of peripheral nociceptors, but also by direct axonal stimulation of nervous trunks. Is is hardly to tolerated by patients since ischemia and mechanical compression induce an activation of C fibres, resistent to ischemia. A beta fibres are involved as well, due to the activation of low-threshold mechanoceptors.

[Human error in the anesthesiological field. Up to what point is it possible to speak of prevention?].

Human error (the act of judging true what is false and false what is true) has ever played and plays a significant role in the occurrence of incidents during anaesthesia. Purpose of the study. The Authors wanted to study how the different Authors analyzed the problem and to outline indications for preventive measures. Materials and methods. For this purpose we have selected papers and their references published on Journals indexed on Index. Medicus (1966-1996). The key words have been: anaesthesia or anesthesia, human error, incident and critical incident. We analyzed papers where human error in anaesthesia as a source of accidents was the main topic. The problem is analyzed starting from a classification of different errors and quantified with proper cognitive methods. Finally preventive measures are proposed. Results, Contribution of human error to the occurrence of accidents in anaesthesia ranges from 37% to 87% according to different. Authors employed techniques and sample size. Proper corrective measures on human, instrumental and environmental factors can lead to increased prevention. Conclusions. Human error exists now and will ever exist. Its gravity depends on its consequences and on preventive measures adopted.
