[Cancellation in CMA: incidence and causes].

Introduction: Major Ambulatory Surgery (MAS) units are becoming increasingly important and require correct management. One of the principal improvement parameters in hospital management policy is the rate of cancellations of elective surgery.

Material And Method: We designed a retrospective, observational study by selecting all the patients operated on in our MAS unit from 1995 to 2009: 16.

[Prevalence of anal diseases after Scopinaro's biliopancreatic bypass for super-obese patients].

Introduction: Biliopancreatic diversion by Scopinaro (BD) is a mixed (malabsortive and restrictive) bariatric technique that is successful in achieving long lasting weight lost in super obese patients. In fact, the diarrhoea (steatorrhea) that is expected after any malabsortive technique can sometimes cause significant nutritional changes and anal disease: these patients are frequently referred to our coloproctology outpatient clinic due to haemorrhoids, fissures, anal sepsis and fistula basically due to changes in quality and quantity of their faeces. The aim of this paper is to find out not only the prevalence of anal disease in our series of super obese surgical patients but also to compare the incidence between the two surgical techniques we perform in our department.

Results of biliopancreatic diversion after five years.

Background: Gastric restrictive procedures, currently the most popular surgical operations for morbid obesity, have proved to be effective in initiating weight loss, but questions regarding their long-term efficacy in weight maintenance have arisen. Biliopancreatic diversion (BPD) is a mixed and complex technique that has shown good long-term results. There are no series with long-term follow-up of BPD in Spain.

Vertical banded gastroplasty: is it a durable operation for morbid obesity?

Background: Long-term follow-up is important in the evaluation of results of bariatric operations. The authors followed vertical banded gastroplasty (VBG) in an ongoing database.

Methods: From 1986 to 1999, 123 VBGs were performed in one surgical ward.

Effect of vertical banded gastroplasty on hypertension, diabetes and dyslipidemia.

Background: Operations for morbid obesity that are effective in inducing weight loss improve blood pressure, glycemic control and dyslipidemia. Our purpose was to study the effectiveness of VBG in improving hypertension, diabetes and dyslipidemias in morbidly obese patients.

Methods: Retrospective analysis of a cohort of 80 morbidly, obese patients was conducted.
