[Developing a competence center for obesity and metabolic surgery-Experiences from two different clinics].

Abstract

Background: Due to the high incidence of obesity and the effectiveness of obesity (metabolic) surgery, the number of metabolic operations and the formation of certified obesity centers continue to increase. The aim of this study was to compare the experiences of two hospitals during establishing a certified obesity center in Heidelberg/Salem (HD/Salem) and in Baden-Baden (Bad).

Material and methods: The operation numbers, surgical procedures, the need for revision and the length of hospital stay were analyzed from August 2012 to June 2015 in HD/Salem and from May 2017 to December 2021 in Bad. In addition, a structured survey of patients took place to find out the preferred discharge date. The statistical evaluation was carried out with T-tests and χ²-tests for binary data.

Results: This analysis comprised 387 patients (181 patients Bad). There were 258 female patients (131 Bad). The mean age of all patients was 44.6 years (44.0 years Bad), the mean body mass index was 47.5 kg/m² (47.0 kg/m² Bad). In 12 of 206 patients (5.8%) from HD/Salem and 8 of 181 patients (4.4%) from Bad a revision was necessary. The average length of hospital stay decreased in HD/Salem from 6.5 days to 4.4 days (p < 0.05) and from 3.7 days to 3.4 days in Bad. Late revisions were necessary in HD/Salem in 4 of 206 patients (2.2%) and in Bad in 8 out of 181 patients (4.4%). The needed number of yearly operations required for certification was achieved for the first time in HD/Salem after 7 years and in Bad after 4 years.

Conclusion: Building an obesity center at a different location from scratch to certification can be initiated and carried out by one experienced surgeon without loss of treatment quality regarding morbidity and mortality. From the start, the team should be familiar with early and late complications of metabolic surgery.
