摘要

Introduction

Within the framework of this analysis the duration of the hospital stay of elective minimally invasive oncological colon resections and sigma resections in cases of sigmoid diverticulitis between 2013 and 2024 from the corresponding StuDoQ registers were investigated. The aim of the analysis was to identify risk factors for an extended duration of the hospital stay.

Method

The data from the StuDoQ registers “Colon cancer” and “LapSigma” were examined. Emergency interventions, open/endoscopic interventions and converted operations were excluded. The shared variables of both registers were age, sex, body mass index (BMI), the American Society of Anesthesiologists (ASA) class, the duration of surgery and the access at the start of surgery. For colon cancer the localization of the tumor, the pT stage, the pN stage and the M status were evaluated in addition to the surgical intervention. For the “LapSigma” register the indications for the intervention and the classification were investigated. Univariate and multivariate analyses were carried out.

Results

In the “Colon cancer” register between 2013–2024 from 52,203 patients 17,930 could be included in the analysis. The median duration of hospital stay was 8 days (IQR 6–11). The multivariate analysis showed that the ASA class (odds ratio 1.44, 95% CI 1.37–1.52, p<0.001) and the M status (odds ratio 1.24, 95% CI 1.24–1.34, p<0.001) were risk factors for a hospital stay lasting longer than 8 days. In the “LapSigma” register between 2013 and 2024 there were a total of 33,669 patients of whom 26,324 patients could be included in the analysis. The median duration of hospital stay was 7 days (IQR 6–8). The multivariate analysis showed that the ASA class (odds ratio 1.35, 95% CI 1.29–1.42, p<0.001) and the indications for surgery (odds ratio 1.62, 95% CI 1.53–1.73, p<0.001) had a significant influence on the duration of hospital stay.

Discussion

Within the framework of the analysis many of the variables investigated showed a significant effect with a very high number of cases. Under closer examination, particularly for laparoscopic sigma resections for a sigmoid diverticulitis, a higher ASA class and indications for surgery (early elective and elective with bleeding) are decisive for an extended duration of hospital stay. For oncological resections a higher ASA class and a positive M status in particular were shown to be significant risk factors for an extended hospital stay.
