Efficient liver regeneration following temporary portal vein embolization with absorbable gelatin sponge powder in humans.

Purpose: To report initial experience of temporary portal vein embolization (PVE) with a powdered form of absorbable gelatin sponge before major liver resection.

Materials And Methods: From 2009-2013, 20 patients (6 women and 14 men; median age, 61.5 y ± 2.

Synchronous pyogenic liver abscess and acute cholecystitis: how to recognize it and what to do (emergency cholecystostomy followed by delayed laparoscopic cholecystectomy).

Background: The treatment of synchronous pyogenic liver abscess (PLA) and acute cholecystitis (AC) may be challenging. Moreover, because of the similarity of symptoms and the suboptimal accuracy of ultrasound (US), PLA(s) may be undetected, unless a computer tomography (CT) scan is performed. The aims of this study were (1) to evaluate the results of emergency cholecystostomy (CS) and late laparoscopic cholecystectomy (LC) in such a population and (2) to identify the criteria for selecting patients with AC and a high risk of having synchronous PLA(s) for referral for a CT scan.

Laparoscopic major hepatectomy can be safely performed with colorectal surgery for synchronous colorectal liver metastasis.

Background: The optimal strategy for resectable synchronous colorectal liver metastases remains controversial. Although some authors advocate a staged treatment, an increasing number of studies have reported that combined colorectal and liver resection is safe. Laparoscopic combined resection in primary colorectal cancer with synchronous liver metastases has been reported but there are no specific data for major liver resections.

Predictive factors for hypertrophy of the future remnant liver after selective portal vein embolization.

Background: To analyze predictive factors of hypertrophy of the nonembolized future remnant liver (FRL) after transhepatic preoperative portal vein embolization (PVE) of the liver to be resected.

Materials And Methods: Age, gender, indocyanin green clearance test, chemotherapy before PVE, type of chemotherapy, operators, extent of PVE, radiofrequency ablation (RFA) associated with PVE, time delay between PVE and surgery, and platelet count were retrospectively evaluated as predictive factors for hypertrophy of FRL in 107 patients with malignant disease in noncirrhotic liver. PVE targeted the right liver lobe [n = 70] or the right liver lobe and segment IV [n = 37] when FRL/total liver volume ratio was below 25% in healthy liver or 40% in altered liver.
