A propensity score-matched case-control comparative study of laparoscopic and open liver resection for hepatocellular carcinoma.

Background: The aim of this study was to compare the perioperative and long-term oncologic outcomes of laparoscopic liver resection (LLR) and open liver resection (OLR) for single hepatocellular carcinoma (HCC) in case-controlled patient groups using the propensity score.

Patients And Methods: Between January 2005 and February 2013, 292 patients underwent surgical resection for HCC. Of these, 202 patients who underwent surgical resection for initial treatment for a single mass were enrolled.

Benefit of systematic segmentectomy of the hepatocellular carcinoma: revisiting the dye injection method for various portal vein branches.

Background: Systematic segmentectomy is useful in treating small hepatocellular carcinoma in the cirrhotic liver. However, accomplishment of an exact systematic segmentectomy still remains a challenging procedure because of the variable anatomy of portal branches. We evaluated the usefulness of the dye injection method for systematic segmentectomy, which focuses on the various patterns of portal vein (PV) branches feeding the tumor.

An imported case of cystic echinococcosis in the liver.

A 25-year-old Uzbek male presented with right upper abdominal pain for 20 days. On radiologic studies, a huge cystic mass was noticed in the right liver which was suspected as parasitic. The patient received right hepatic segmentectomy (segment 7), and the surgically resected mass was confirmed as cystic echinococcosis (CE), measuring 10.

Living-donor liver transplant with an interposition graft of the inferior vena cava for hepatocellular carcinoma: beyond the Milan criteria and within the UCSF criteria.

Living-donor liver transplant for a big hepatocellular carcinoma located in the caudate lobe is challenging owing to dissemination of cancer cells during recipient hepatectomy. We report a case of living-donor liver transplant using the right side of the liver of a living donor combined with inferior vena cava interposition graft after en bloc resection of the liver and retrohepatic inferior vena cava for hepatocellular carcinoma in the caudate lobe. A 50-year-old man with chronic hepatitis B cirrhosis developed hepatocellular carcinoma in the caudate lobe and segment 5.

The impact of old age on surgical outcomes after pancreaticoduodenectomy for distal bile duct cancer.

Backgrounds/aims: To compare surgical results and survival of two groups of patients, age ≥70 vs. age <70, who underwent pancreaticoduodenectomy and to identify the safety of this procedure for elderly patients for the treatment of distal common bile duct (CBD) cancer.

Methods: Between January 2003 and December 2009, 55 patients who underwent pancreaticoduodenectomy for the treatment of distal CBD cancer at Keimyung University Dong San Medical Center were enrolled in our study.

Inflammatory pseudotumors mimicking intrahepatic cholangiocarcinoma of the liver; IgG4-positivity and its clinical significance.

Background: Inflammatory pseudotumor (IPT) of the liver is a benign condition with a good prognosis. However, it is difficult to distinguish clinical and radiological findings of IPT from those of malignancies. The aims of this study are to determine the clinical, radiological, and pathological characteristics, particularly relating to the role of the autoimmune mechanism in the development of inflammatory pseudotumours (IPTs) of the liver, and to suggest appropriate diagnostic and therapeutic strategy.

Determination of malignant and invasive predictors in branch duct type intraductal papillary mucinous neoplasms of the pancreas: a suggested scoring formula.

Prediction of malignancy or invasiveness of branch duct type intraductal papillary mucinous neoplasm (Br-IPMN) is difficult, and proper treatment strategy has not been well established. The authors investigated the characteristics of Br-IPMN and explored its malignancy or invasiveness predicting factors to suggest a scoring formula for predicting pathologic results. From 1994 to 2008, 237 patients who were diagnosed as Br-IPMN at 11 tertiary referral centers in Korea were retrospectively reviewed.

[Risk factors for early recurrence after surgical resection for hepatocellular carcinoma].

Background/aims: Early recurrence (ER) after liver resection is one of the most important factors impacting the prognosis and survival of patients with hepatocellular carcinoma (HCC). This study aimed to identify the factors associated with ER after curative hepatic resection for HCC.

Methods: From the July 2000 to July 2006, 144 patients underwent hepatic resection for HCC at a single institution.

Optimal cycle of intermittent portal triad clamping during liver resection in the murine liver.

We designed this experimental study to determine the optimal cycle for intermittent inflow occlusion during liver resection. A cycle of intermittent clamping (IC) for 15 minutes of ischemia followed by reperfusion for 5 minutes during liver resection is currently the most popular protocol used by experienced liver centers. As each period of reperfusion is associated with bleeding, longer periods of clamping would be advantageous.

Tip for microlaparoscopic cholecystectomy: easy removal of the gallbladder after laparoscopic cholecystectomy using the three-port technique.

The standard laparoscopic cholecystectomy usually requires four trocars: two 10-mm and two 5-mm trocars. With the development of mini-instruments, laparoscopic surgeons have developed the two- or three-port techniques. The selection of the number and size of trocars depends on the surgeon's experience and preferences.
