Anomalous biliary and vascular anatomy-Potential pitfalls during cholecystectomy.

Laparoscopic cholecystectomy is usually a low-risk procedure associated with a short stay and a low rate of conversion to open surgery. Complications are sometimes associated with anomalous vascular or biliary anatomy. Outlined below are the variations in vascular and biliary anatomy which may result in complications either due to involvement in the inflammatory process or inadvertent division during dissection.

A systematic review of the role of hepatectomy in the management of metastatic renal cell carcinoma.

AIM: This review sought to systematically appraise the literature to establish the role of hepatectomy in treating renal cell carcinoma hepatic metastases. METHOD: Medline and EMBASE were systematically searched for papers reporting survival of patients who underwent hepatectomy for metastatic renal cell carcinoma. RESULTS: Six studies containing 140 patients were included. There were no randomised controlled trials. Perioperative mortality was 4.3%, with reported morbidity between 13 and 30%. Patients with metachronous presentation, and a greater time interval between resection of primary tumour and development of metachronous metastases, appeared to have better survival. There was no difference in survival between patients with solitary and multiple metastases. CONCLUSION: Few patients with hepatic metastases from renal cell carcinoma are suitable for hepatectomy as metastatic disease is usually widespread. Selected patients may experience a survival benefit, but identifying these patients remains difficult.

Effect of specialist decision-making on treatment strategies for colorectal liver metastases.

BACKGROUND: One hundred and ten patients were treated with palliative chemotherapy, of whom 53 had liver-only disease and had not been reviewed by a specialist liver surgeon. One scan was excluded as all reviewers felt it to be of insufficient quality to assess. Improved surgical technique and better chemotherapeutic manipulation of metastatic disease has increased the number of patients eligible for potentially curative resection of colorectal liver metastases. The rapid evolution in this field suggests that non-specialist decision-making may lead to inappropriate management. This study aimed to assess the management of colorectal liver metastases by non-liver surgeons. METHODS: All patients who underwent chemotherapy with palliative intent for metastatic colorectal cancer at a regional oncology centre between 1 January and 31 December 2009 were identified from a prospectively maintained local database. Six resectional liver surgeons blinded to patient management and outcome reviewed pretreatment imaging and assigned each scan a score based on their own management choice. A consensus decision was reached on the appropriateness of palliative chemotherapy. RESULTS: One hundred and ten patients were treated with palliative chemotherapy, of whom 53 had liver-only disease and had not been reviewed by a specialist liver surgeon. One scan was excluded as all reviewers felt it to be of insufficient quality to assess [corrected]. Tumours in 33 patients (63 per cent) were considered potentially resectable, with a high level of interobserver agreement (κ = 0 · 577). When individual approach to management was considered, interobserver agreement was less marked (κ = 0 · 378). CONCLUSION: Management of patients with colorectal liver metastases without the involvement of a specialist liver multidisciplinary team can lead to patients being denied potentially curative treatments. Management of these patients must involve a specialist liver surgeon to ensure appropriate management.
