Abstract

INTRODUCTION: Resection, on-table lavage (OTL) and primary anastomosis is the treatment of choice for the obstructed left colon. OTL is time-consuming, requires considerable mobilisation/bowel handling, an enterotomy and potentially exposes the patient to mesenteric vascular injury, faecal contamination and a prolonged ileus. We have assessed outcome following primary resection and anastomosis without prior lavage.PATIENTS AND METHODS: Twenty-four consecutive, obstructed patients underwent splenic flexure mobilisation and high anterior resection (concomitant small bowel resection in 2) with primary side-to-side colorectal anastomosis without either prior lavage or covering stoma. Outcome was audited.RESULTS: Twenty-four patients, 17 female aged 48–92 years (median. 76 years) presented with left-sided obstruction due to carcinoma (Dukes' B [3], C [6], D [1]) or chronic diverticulitis (14). Median operative time was 85 min (range, 40–105 min). Colonic ileus resolved on day 2 (29%) and day 3 (58%). Median hospital stay was 7 days (range, 6–72 days); 92% discharged by day 10. There were no deaths or re-admissions. A return to theatre followed a reactionary haemorrhage in one. This latter patient's anastomosis leaked on day 4 (no faecal contamination) and was converted to an end stoma. Urinary and wound infections were seen in two. Late complications comprised two anastomotic strictures; both responded to balloon dilatation at 5 months.CONCLUSIONS: Resection and primary anastomosis without on-table lavage is an easy, practical, predictable and safe treatment option for left-sided colonic obstruction with minimal complications.
