Sigmoid resection in diverticulitis is one of the most frequently performed colonic operations. A minimally invasive approach by laparoscopy is the surgical gold standard. For a few years now, sigmoid resections have also been performed robotically (da Vinci System). It is unclear whether there are relevant differences between the two procedures in terms of functional outcome.
A postoperative follow-up was performed on all patients who underwent laparoscopic or robotic sigmoid resection for diverticulitis between November 2013 and November 2018, with a minimum interval of 6 months between surgery. Continence disorders, the development of symptoms compared to preoperative, changes in bowel movement (constipation, diarrhoea), impairment in daily life and pain were recorded. Differences between the groups were checked for statistical significance using the chi-square test.
During the study period, a total of 106 minimally invasive sigmoid resections for diverticulitis were performed (laparoscopic: n = 46, robot-assisted: n = 60). Of these, 74 patients (70%; laparoscopic: n = 28, robot-assisted: n = 46) answered the questionnaire and were included in the evaluation. Continence disorders were reported in a total of 22% of cases. There was no statistically significant difference between the groups in any of the variables surveyed.
With regard to functional results after minimally invasive sigmoid resection for diverticulitis, laparoscopic and robot-assisted sigmoid resection can be considered equivalent procedures.
