Background
The aims of the study were to determine the radiological leak rate in those patients who had undergone a resection for left-sided colorectal cancer and to see if the presence of a leak can be related with the postoperative clinical period. We also aimed to identify any common factors between patients with leak.
Methods
A retrospective analysis of prospectively collected data of all patients who underwent a left-sided colorectal cancer resection with formation of a defunctioning ileostomy was undertaken. Between 2005 and 2010, 418 such patients were identified.
Results
A water-soluble contrast enema was performed in 339 patients (81.1 %). Of these, 24 (7.1 %) were reported to show an anastomotic leak. Data for these 24 patients is presented in this study.
Twenty-three (95.8 %) of the leaks occurred in patients who had undergone an anterior resection; 95.8 % of the patients with a leak were male. Fifteen (62.5 %) patients underwent neo-adjuvant radiation. The mean length of stay in those patients shown to have a subsequent radiological leak was 18.8 days (median), compared with the overall unit figures of 12 days. Only 29.2 % of the patients who had a leak identified had an uncomplicated postoperative period. Overall 87.5 % of the patients had a reversal of the ileostomy.
Conclusions
Radiological leakage is not uncommon. The majority of patients, who were shown to have a radiological leak in this study, were male, had undergone an anterior resection, had received neo-adjuvant radiation, had a longer initial length of stay and had postoperative complications. Water-soluble contrast enemas could be selectively used in patients with these characteristics.
