Evidence-based value of prophylactic drainage in gastrointestinal surgery: a systematic review and meta-analyses

Incidence and management of biliary leakage after hepaticojejunostomy

This study analyzes the change in the management of biliary leakage after hepaticojejunostomy. Between 1993 and 2003 all patients (n = 1033) were studied with a hepaticojejunostomy as part of a pancreatoduodenectomy (n = 486), proximal bile duct resection (without liver resection) (n = 35), and biliodigestive bypass for malignant (n = 302) and benign (n = 210) disease. Biliary leakage was defined as the presence of bile-stained fluid (>50 mL) in the abdominal drain more than 24 hours after surgery, proven radiologically or at relaparotomy. The studied patients were divided into two equal periods to analyze the change in management. Overall, 24 of 1033 patients (2.3%) had biliary leakage. In multivariate analysis, a body mass index greater than 35 kg/m2 (P = .012), endoscopic biliary drainage (P = .044), and an anastomosis on the segmental bile ducts (P < .001) were independent predictors of leakage. Management in the first half of the study period (1993-1998) versus the second half (1999-2003) was maintenance of operatively placed drains (18% vs. 15%, respectively, P = 1.000), percutaneous transhepatic biliary drainage (18% vs. 69%, respectively, P = .012), surgical drainage (55% vs. 8%, respectively, P = .023), and re-hepaticojejunostomy (9% vs. 8%, respectively, P = 1.000). There was no mortality in the patients with biliary leakage. Leakage after a hepaticojejunostomy is a relatively rare complication without mortality and can safely be managed with percutaneous transhepatic biliary drainage.

Care after colonic operation--is it evidence-based? Results from a multinational survey in Europe and the United States

BACKGROUND

Despite clinical evidence showing that steps can be taken perioperatively to enhance postoperative recovery and decrease morbidity in colonic operation patients, there is no comprehensive information on how widespread such practices are, or the combination of such steps into effective multimodal rehabilitation (fast-track) colonic surgery programs to decrease hospital stay. This survey investigated clinical practice around colonic operations across Europe and the United States.

METHODS

The survey was conducted in 295 hospitals in the United Kingdom, France, Germany, Italy, Spain, and the United States. Details of perioperative care and postoperative recovery were recorded for 1,082 patients who had undergone elective colonic operations and who were discharged (or died) over a 2-week period (United States: up to 4 weeks).

RESULTS

Preoperative bowel clearance was used in >85% of patients. A nasogastric tube was left in situ postoperatively in 40% versus 66% of patients in the United States and Europe, respectively, and was removed about 3 days postoperatively. It took 3 to 4 days until 50% of the patients first tolerated liquids and 4 to 5 days until 50% of patients were eating and having a bowel movement. Postoperative ileus was found to persist for over 5 days in approximately 45% of patients. Mean length of postoperative hospital stay was over 10 days in the United Kingdom, France, Germany, Italy, and Spain, and 7 days in the United States, compared with 2 to 5 days reported in trials of fast-track colonic surgery programs.

CONCLUSIONS

Strategies that can contribute to improved recovery and reduced complications after colonic operations do not appear to be applied optimally in clinical practice across Europe and the United States. These findings indicate a potential for major improvements in outcomes and reduction of costs if peri- and postoperative care can be adjusted to be in line with published evidence.

Role and limitations of laparoscopic liver resection of colorectal metastases

BACKGROUND

The current experience of laparoscopic liver resection is reviewed focusing on the role and limitations of resection of colorectal metastases. Surgical technique, outcome, and the main controversies regarding the procedures are described.

METHODS

Current literature on laparoscopic liver resection is reviewed based on reports identified following a specified PubMed search.

RESULTS

Available evidence indicates that laparoscopic liver resection can be made safely in selected patients with comparable duration of surgery, blood loss, tumour clearance, and mortality to that of open resection. Tumours localised peripherally in the left lateral segments of the liver or in segments IV-VI seem to be best suited for laparoscopic resection. The laparoscopic approach may be beneficial to the patients as compared to conventional resection but randomised trials are pending. Laparoscopic resection of colorectal liver metastases is described in a small number of patients only. The long-term outcome following such resections is not adequately documented.

CONCLUSIONS

Laparoscopic liver resection is a promising technique with a comparable short-term outcome to that of open procedures but with the potential advantages of minimal invasive treatment. The technique should be further evaluated in properly designed trials. Laparoscopic resection of colorectal liver metastases should not be performed on a regular basis until long-term results are defined.
