Half-Pringle Maneuver: A Useful Tool in Laparoscopic Liver Resection

Introduction: Laparoscopic liver resections are becoming a common procedure, and bleeding remains the major concern during parenchymal transection. Total vascular inflow occlusion can be performed, but ischemic reperfusion injuries can lead to postoperative morbidity. On the other hand, hemihepatic inflow occlusion, leading to hemiliver ischemia, decreases the amount of liver parenchyma submitted to reperfusion damage and offers the advantage of reduced blood loss. Objective: The aim of this work was to describe our experience with laparoscopic the half-Pringle maneuver for segmentar or nonanatomic liver resctions. Patients and Methods: Eight patients submitted to laparoscopic liver resection in a single tertiary center. Results: There were 5 women and 3 men with a mean age of 40.2 years (range, 26-54). Mean tumor size was 4.1 cm (range, 2.6-6.0), and mean hospital stay was 3.1 days (1-5). There were 3 liver adenomas, 2 hepatocellular carcinomas, 1 metastatic melanoma, 1 metastatic colorectal carcinoma, and 1 peripheral colangiocarcinoma. No postoperative complications or mortalities were observed. Conclusions: Results demonstrate that laparoscopic liver resection with the half-Pringle maneuver is feasible and safe and may be included in the technical armamentarium of laparoscopic liver resections for a selected group of patients

Portal vein thrombosis after esophagogastric devascularization and splenectomy in schistosomal portal hypertension patients: What's the real importance?

CONTEXTO: A complicação mais frequente após a desconexão ázigo-portal e esplenectomia em doentes com esquistossomose mansônica hepatoesplênica é a trombose da veia porta. OBJETIVOS:Avaliar a incidência, os fatores preditivos dessa complicação, assim como, a evolução clínica, laboratorial, endoscópica e ultrassonográfica desses pacientes. MÉTODOS: Foram analisados retrospectivamente os prontuários de 155 doentes esquistossomóticos submetidos a desconexão ázigo-portal e esplenectomia. RESULTADOS: Trombose de veia porta foi observada em 52,3% dos pacientes, sendo 6,5% de trombose total e 45,8% de trombose parcial. Os pacientes que evoluíram com trombose de veia porta apresentaram mais frequentemente diarreia no pós-operatório. Febre foi evento habitual que ocorreu em 70% dos casos, mais frequente, entretanto, nos doentes com trombose total da veia porta (100%). Trombose de veia mesentérica superior ocorreu em quatro doentes (2,6%), sendo mais frequente entre os com trombose total da veia porta. Não se encontrou diferença estatística quanto aos parâmetros clínicos, laboratoriais, endoscópicos e recidiva hemorrágica no pós-operatório tardio, quando comparados os pacientes com e sem trombose portal. CONCLUSÕES: A trombose de veia porta no pós-operatório da desconexão ázigo-portal e esplenectomia é evento frequente, sem nenhum fator preditivo para sua ocorrência; na maioria dos casos a trombose é parcial e apresenta evolução benigna, com baixa morbidade; trombose total da veia porta está mais frequentemente associada à trombose da veia mesentérica superior, com elevada morbidade; a trombose da veia porta, parcial ou total, não acarretou complicações no período pós-operatório tardio.CONTEXT: Portal vein thrombosis is the most frequent complication after esophagogastric devascularization and splenectomy for hepatosplenic schistosomosis. OBJECTIVE: To evaluate portal vein thrombosis in 155 patients with schistosomal portal hypertension submitted to esophagogastric devascularization and splenectomy. METHODS: We retrospectively analyzed not only the incidence and predictive factors of this complication, but also clinical, laboratorial, endoscopic and Doppler sonography outcome of these patients. RESULTS: Postoperative portal thrombosis was observed in 52.3% of the patients (partial in 45.8% and total in 6.5%). Postoperative diarrhea was more frequent in patients with portal vein thrombosis. Fever was a frequent postoperative symptom (70%) but occurred in a higher percentage when total portal vein thrombosis was present (100%). Superior mesenteric vein thrombosis occurred in four patients (2.6%) and was associated with total thrombosis of the portal vein. There was no statistical difference between patients with and without portal vein thrombosis according to clinical and endoscopic parameters during late follow-up. It was not possible to identify any predictive factor for the occurrence of this complication. CONCLUSIONS: Portal vein thrombosis is an early and frequent event after esophagogastric devascularization and splenectomy, usually partial with benign outcome and low morbidity. Total portal vein thrombosis is more frequently associated with a high morbidity complication, the superior mesenteric vein thrombosis. Long-term survival was not influenced by either partial or total portal thrombosis
