Abstract

Aim: The aim of this study was to investigate, by comparing clinical and histological outcomes, whether laparoscopic (hybrid) wedge resection (LWR) could be a less invasive and safe alternative to laparoscopic oncological colon resection (OCR) for patients with an endoscopically unresectable, suspected benign, colon polyp.

Method: All patients with an endoscopically unresectable colon polyp who were referred for surgery between 2009 and 2018 and without biopsy-proven colon cancer were identified from a prospectively maintained database. Patients with macroscopic features of malignancy during endoscopy were excluded. Clinical and histological results for patients who underwent OCR or LWR were reviewed.

Results: One hundred-and-twenty-two patients were included. Ninety-seven patients underwent OCR and 25 LWR. Major complications occurred in 16.7% (n = 16) of the OCR group compared with 4.0% (n = 1) of the LWR group (p = 0.06). In the OCR group the anastomotic leakage rate was 6.3% (n = 6) and the mortality rate 3.1% (n = 3). No anastomotic leakage or deaths occurred in the LWR group. The median length of hospital stay after OCR was 5 days [interquartile range (IQR) 5-9 days)] compared with 2 days (IQR 2-4 days) after LWR (p < 0.0001). Definite pathology showed a malignancy rate of 4.2% (n = 4) in the OCR group and 4.0% (n = 1) (without high-risk features) in the LWR group.

Conclusion: This study shows that LWR was associated with significantly lower complication rates and acceptable oncological risks compared with OCR. Therefore we suggest that LWR is a safe alternative treatment, next to other endoscopic options. The treatment that is most suitable for an individual patient should be discussed in a multidisciplinary meeting.
