Postoperative Outcomes After Laparoscopic Liver Resections in Low and High-Volume Centers: A Multicentric Case-Matched Comparative Study.

Background: Laparoscopic liver resection (LLR) is the gold standard for liver resections. Despite its feasibility and safety in high-volume centers (HVC), its performance is controversial in low-volume centers (LVCs). We aimed to evaluate the results of LLR performed in LVC.

Pancreas-preserving management in reinterventions for severe pancreatic fistula after pancreatoduodenectomy: a systematic review.

Background: Life-threatening postoperative pancreatic fistula (LTPOPF) is the most feared complication after pancreatoduodenectomy (PD). Although completion pancreatectomy (CP) is usually performed when radiological management fails, the associated morbidity and mortality rates remain high. Here, we reviewed pancreas-preserving alternatives to CP.

Hepatocellular carcinoma in situs ambiguus: CT findings of a rare disposition.

Heterotaxic disorders or situs ambiguus are uncommon anatomical variations constituted by a partial mirror-image disposition of intra thoracic and/or abdominal solid organs. These variations are challenging because rarely met in a surgeon's career, and because of the coexistence of numerous other anatomical variants, like ones related to the asymmetrical organs, causing difficulties when a surgical management is required. We report the case of a 57-year-old patient presenting liver cirrhosis in which regular follow-up discovered a hepatocellular carcinoma of the right part of the liver associated to numerous anatomical variations in the setting of a situs ambiguus.

Volumetric gain of the liver after major hepatectomy in obese patients: a case-matched study in 84 patients.

Objective: The objective was to determine the liver volumetric recovering capacity and postoperative course after major hepatectomy in obese patients through a case-matched study.

Background: In literature, the impact of obesity on liver recovering has been analyzed only indirectly in terms of morbimortality but never through volumetric assessment.

Patients And Method: Between 2005 and 2011, 42 patients with body mass index (BMI) 30 or higher (Ob group) underwent major hepatectomy and were matched with 42 patients with BMI 25 or lower (NonOb group) on the magnitude of resection (number of resected segments ±1, remnant liver volume to total liver volume, RLV/TLV, ±5%).

Liver endometriosis presenting as a liver mass associated with high blood levels of tumoral biomarkers.

Endometriosis is a dissemination of endometrial-like tissue outside the uterine cavity, responsible for pain and impaired fertility in women of childbearing age. Although endometriosis generally occurs in the pelvis, it can be located further away. We describe the case of a 35-year-old woman who was admitted for further evaluation of a cystic mass of the liver that had invaded the right ventricle and caused pain.

Mechanisms of splenic hypertrophy following hepatic resection.

Background: Following hepatic resection, liver regeneration has been associated with concurrent splenic hypertrophy. The mechanisms of this phenomenon are unknown, may be multiple and include: splanchnic sequestration caused by a reduction in the hepatic mass; hepatic growth factors that may indirectly act on the spleen, and the redistribution of the total reticuloendothelial system.

Methods: Seventy-five patients (40 males; median age: 60 years) who underwent minor (16%) or major (84%) hepatectomy between September 2004 and October 2009 were included.

Atrial embolism caused by portal vein embolization: Treatment by percutaneous withdrawal and stenting.

Hepatectomy remains the only curative treatment for many primary and secondary liver cancers. Portal vein embolization (PVE) has been used to increase the volume of the future liver remnant and thus lower the risk of small-for-size syndrome and postoperative liver failure. This technique has proven its safety, with a low post-procedure morbidity rate.

Right hepatectomy with extra-hepatic vascular division prior to transection: intention-to-treat analysis of a standardized policy.

Background: Right hepatectomy (RH) is the most common type of major hepatectomy and can be achieved without portal triad clamping (PTC) in non-cirrhotic liver. The present study reviews our standardized policy of performing RH without systematic PTC.

Methods: One hundred and eighty-one consecutive RH were performed in non-cirrhotic patients, with division of the right afferent and efferent blood vessels prior to transection, without systematically using PTC.
