The majority of colorectal resections require an open approach, even in units with a special interest in laparoscopic surgery.

AIM: Proponents suggest that laparoscopic colorectal resection might be achievable in up to 90% of cases, while keeping conversion rates below 10%. This unselected prospective case series reports on the proportion of patients having a completed laparoscopic colorectal resection in two units where laparoscopic colorectal practice is well established and readily available. METHOD: All patients undergoing elective and emergency colorectal resection during a 6-month period were identified. The underlying pathology and the surgical approach (laparoscopic or open) were recorded. The contraindications to laparoscopic resection were also documented. The need and rationale for conversion to an open approach were recorded. RESULTS: In total, 205 consecutive patients (160 elective and 45 emergency procedures) underwent colorectal resection for malignancy [117 (57%) patients] and benign pathology [88 (43%) patients]. Laparoscopic resection was attempted in 127/205 (62%) patients and 31/127 (24%) of these were converted to open surgery. The main reasons for not attempting laparoscopic resection were locally advanced disease and emergency surgery. The commonest reasons for conversion were advanced disease and to allow completion of rectal dissection and/or cross-stapling of the rectum. CONCLUSION: Despite a special interest in laparoscopic colorectal surgery of the two colorectal units who provided the data for this study, fewer than half (96/205; 47%) of the patients in this consecutive unselected series who were undergoing major colorectal resection had the procedure completed laparoscopically.

Staple line haemorrhage following laparoscopic left-sided colorectal resections may be more common when the inferior mesenteric artery is preserved.

BACKGROUND: Anastomotic bleeding following stapled left-sided colorectal resections is uncommon. There have been few reports on the incidence, severity, management and outcome of such stapled line haemorrhage in the literature. Here, we report our experience of anastomotic bleeding from a stapled anastomosis in laparoscopic left-sided colorectal surgery. METHODS: Data were collected prospectively on all patients undergoing laparoscopic colorectal surgery from 2003. Patients who had a left-sided stapled anastomosis requiring intervention for staple line haemorrhage were studied. Patients who underwent laparoscopic surgery for benign colorectal disease were compared with those who underwent laparoscopic surgery for a malignant condition. Risk factors for bleeding, management and outcome are reported. RESULTS: Over a 5-year period, 143 patients underwent laparoscopic left-sided colorectal surgery, 72 for benign disease and 71 for a malignant condition. Postoperative anastomotic bleeding occurred in six patients (4%). All were in the benign pathology group, and all had preservation of the inferior mesenteric artery during surgery. None of the patients required operative intervention for staple line haemorrhage. CONCLUSIONS: Anastomotic bleeding from a stapled anastomosis in laparoscopic left-sided colorectal surgery is an infrequent complication and it may be more common with preservation of the inferior mesenteric artery. In the majority, bleeding is self limiting and will settle with nonoperative means. Endoscopic procedures may be useful for confirmation of bleeding and for therapeutic intervention, and may avoid the need for surgical intervention.
