Focal Nodular Hyperplasia: A Rare Indication of Resection

Surgical indications of Focal Nodular Hyperplasia (FNH) remain exceptional except in cases of diagnostic uncertainty, symptomatic lesion or increase of tumour volume. We describe the case of FNH compressing the Inferior Vena Cava (IVC)

Laparoscopic Liver Resection for Malignant Liver Tumors: Preliminary Results of a Multicenter European Study

OBJECTIVE: To assess the feasibility, safety, and outcome of laparoscopic liver resection for malignant liver tumors. SUMMARY BACKGROUND DATA: The precise role of laparoscopy in resection of liver malignancies (hepatocellular carcinoma [HCC] and liver metastases) remains controversial despite an increasing number of publications reporting laparoscopic resection of benign liver tumors. METHODS: A retrospective study was performed in 11 surgical centers in Europe regarding their experience with laparoscopic resection of liver malignancies. Detailed questionnaires were sent to each surgeon focusing on patient characteristics, clinical data, type and characteristics of the tumor, technical details of the operation, and early and late clinical outcome. All patients had radiologic investigations at follow-up to exclude disease recurrence. RESULTS: From February 1994 to December 2000, 37 patients with malignant liver tumors were included in this study. Ten patients had HCC, including 9 with cirrhotic liver, and 27 patients had liver metastases. The mean tumor size was 3.3 cm, and 89% of the tumors were located in the left lobe or in the anterior segments of the right liver. Liver procedures included 12 wedge resections, 9 segmentectomies, 14 bisegmentectomies (including 13 left lateral segmentectomies), and 2 major hepatectomies. The transfusion rate, the use of pedicular clamping, the conversion rate (13.5% in the whole series), and the complication rate were significantly greater in patients with HCC. There were no deaths. Postoperative complications occurred in eight patients (22%). The surgical margin was less than 1 cm in 30% of the patients. During a mean follow-up of 14 months, the 2-year disease-free survival was 44% for patients with HCC and 53% for patients having hepatic metastases from colorectal cancer. No port-site metastases were observed during follow-up. CONCLUSIONS: In patients with small malignant tumors, located in the left lateral segments or in the anterior segments of the right liver, laparoscopic resection is feasible and safe. The complication rate is low, except in patients with HCC on cirrhotic liver. By using laparoscopic ultrasound, a 1-cm free surgical margin should be routinely obtained. The late outcome needs to be evaluated in expert centers

Review of the quality of total mesorectal excision does not improve the prediction of outcome

Aim: A fair to moderate concordance in grading of the total mesorectal excision (TME) surgical specimen by local pathologists and a central review panel has been observed in the PROCARE (Project on Cancer of the Rectum) project. The aim of the present study was to evaluate the difference, if any, in the accuracy of predicting the oncological outcome through TME grading by local pathologists or by the review panel. Method: The quality of the TME specimen was reviewed for 482 surgical specimens registered on a prospective database between 2006 and 2011. Patients with a Stage IV tumour, with unknown incidence date or without follow-up information were excluded, resulting in a study population of 383 patients. Quality assessment of the specimen was based on three grades including mesorectal resection (MRR), intramesorectal resection (IMR) and muscularis propria resection (MPR). Using univariable Cox regression models, local and review panel histopathological gradings of the quality of TME were assessed as predictors of local recurrence, distant metastasis and disease-free and overall survival. Differences in the predictions between local and review grading were determined. Results: Resection planes were concordant in 215 (56.1%) specimens. Downgrading from MRR to MPR was noted in 23 (6.0%). There were no significant differences in the prediction error between the two models; local and central review TME grading predicted the outcome equally well. Conclusion: Any difference in grading of the TME specimen between local histopathologists and the review panel had no significant impact on the prediction of oncological outcome for this patient cohort. Grading of the quality of TME as reported by local histopathologists can therefore be used for outcome analysis. Quality control of TME grading is not warranted provided the histopathologist is adequately trained.SCOPUS: ar.jFLWINinfo:eu-repo/semantics/publishe
