Radiofrequency ablation versus transarterial chemoembolization for unresectable solitary hepatocellular carcinomas sized 5-8 cm.

Objectives: This retrospective review was conducted to compare the efficacy of radiofrequency ablation (RFA) with that of transarterial chemoembolization (TACE) in treating large (5-8 cm) unresectable solitary hepatocellular carcinomas (HCCs).

Methods: Patients with large unresectable solitary HCCs primarily treated by RFA or TACE were reviewed. The primary endpoint was overall survival.

Improved anterior hepatic transection for isolated hepatocellular carcinoma in the caudate.

Background: One of the best treatments for isolated hepatocellular carcinoma in the caudate lobe is major hepatectomy with caudate lobectomy, but it is not suitable for patients with poor liver function reserve. Isolated caudate lobectomy, which is a very difficult operation, is thus an alternative option.

Methods: Here we report an isolated caudate lobectomy with an anterior approach in the treatment of a large hepatocellular carcinoma with underlying cirrhosis, with focus on the technical aspects.

Surgical management of recurrent pyogenic cholangitis: 10 years of experience in a tertiary referral centre in Hong Kong.

Background: Recurrent pyogenic cholangitis (RPC) is common in Asia. Its management differs from centre to centre.

Methods: A retrospective review of 80 patients undergoing surgery for RPC was performed.

Long-term survival analysis of pure laparoscopic versus open hepatectomy for hepatocellular carcinoma in patients with cirrhosis: a single-center experience.

Introduction: Laparoscopic liver resection has been reported as a safe and effective approach to the management of liver cancer. However, studies of long-term outcomes regarding tumor recurrence and patient survival in comparison with the conventional open approach are limited. The aim of this study was to analyze the survival outcome of laparoscopic liver resection versus open liver resection.

Outcome of laparoscopic versus open hepatectomy for colorectal liver metastases.

Background: Liver resection provides one of the best oncological outcomes for liver metastases in patients with colorectal cancer. However, long-term results concerning laparoscopic resection versus open hepatectomy for stage IV colon cancer are still limited. The aim of this study is to compare the survival outcome of laparoscopic liver resection with open liver resection for colorectal metastases.

Impact of antiviral therapy on the survival of patients after major hepatectomy for hepatitis B virus-related hepatocellular carcinoma.

Objectives: To assess whether commencement of antiviral therapy after hepatectomy improves the prognosis of hepatocellular carcinoma (HCC) in preoperatively antiviral-naive patients with chronic hepatitis B virus (HBV) infection.

Design: Retrospective analysis of a prospectively collected database.

Setting: University teaching hospital.

Continuous improvement of survival outcomes of resection of hepatocellular carcinoma: a 20-year experience.

Objective: To investigate the trend of the posthepatectomy survival outcomes of hepatocellular carcinoma (HCC) patients by analysis of a prospective cohort of 1198 patients over a 20-year period.

Background: The hospital mortality rate of hepatectomy for HCC has improved but the long-term survival rate remains unsatisfactory. We reported an improvement of survival results 10 years ago.

Results of percutaneous transhepatic cholecystostomy for high surgical risk patients with acute cholecystitis.

Aim: To assess the efficacy and safety of percutaneous transhepatic cholecystostomy (PTC) in treatment for acute cholecystitis in high surgical risk patients.

Patients And Methods: A retrospective review was carried out from January 1999 to June 2007 on 23 patients, 11 males and 12 females, who underwent PTC for the management of acute cholecystitis at the Department of Surgery, Queen Mary Hospital, Hong Kong, China. The mean age of the patients was 83.

Outcome of severely injured trauma patients at a designated trauma centre in the Hong Kong Special Administrative Region.

Background: The Hong Kong Special Administrative Region (HKSAR) of the People's Republic of China (PRC) has seen significant changes in its trauma service over the last ten years including the implementation of a regional trauma system. The author's institution is one of the five trauma centres designated in 2003. This article reports our initial clinical experience.

Diffuse large B-cell lymphoma associated with chronic inflammation as an incidental finding and new clinical scenarios.

Diffuse large B-cell lymphoma that develops in the setting of long-standing chronic inflammation is typically associated with Epstein-Barr virus, and usually presents as tumor mass involving body cavities, as in pyothorax-associated lymphoma. It is listed as a distinct entity in the latest World Health Organization lymphoma classification. We report four cases that were incidentally discovered on histologic examination, one each in a splenic false cyst, a long-standing hydrocele, an atrial myxoma, and metallic-implant wear debris.

An update on long-term outcome of curative hepatic resection for hepatocholangiocarcinoma.

Background: Hepatocholangiocarcinoma (HCC-CC) is a rare primary liver cancer. Its long-term prognosis is still not well-defined. Results from the Eastern and Western literature have been conflicting and no conclusions can be drawn.

External drainage of pancreatic duct with a stent to reduce leakage rate of pancreaticojejunostomy after pancreaticoduodenectomy: a prospective randomized trial.

Objective: Pancreatic fistula is a leading cause of morbidity and mortality after pancreaticoduodenectomy. External drainage of pancreatic duct with a stent has been shown to reduce pancreatic fistula rate of pancreaticojejunostomy in a few retrospective or prospective nonrandomized studies, but no randomized controlled trial has been reported thus far. This single-center prospective randomized trial compared the results of pancreaticoduodenectomy with external drainage stent versus no stent for pancreaticojejunal anastomosis.

Prospective randomized trial on low-pressure versus standard-pressure pneumoperitoneum in outpatient laparoscopic cholecystectomy.

Inpatient low-pressure pneumoperitoneum laparoscopic cholecystectomy (LPLC) has been shown to have less postoperative pain (especially shoulder-tip pain). No report so far has documented the use of lower-pressure pneumoperitoneum in outpatient laparoscopic cholecystectomy (LC). A prospective randomized trial was conducted in Tung Wah Hospital, Day Surgery Centre from January 2004 to December 2004.

Outpatient laparoscopic cholecystectomy in Hong Kong Chinese -- an outcome analysis.

Background: Laparoscopic cholecystectomy (LC) is now the procedure of choice for symptomatic gallbladder disease. Although many recent studies, mostly from abroad, report that it can be performed safely in the outpatient setting, the experience of outpatient LC in Hong Kong is still limited. This retrospective study evaluated the feasibility, safety and patient acceptance of outpatient LC in Hong Kong Chinese patients.

Improving perioperative outcome expands the role of hepatectomy in management of benign and malignant hepatobiliary diseases: analysis of 1222 consecutive patients from a prospective database.

Objective: To assess the trends in perioperative outcome of hepatectomy for hepatobiliary diseases.

Methods: Data of 1222 consecutive patients who underwent hepatectomy for hepatobiliary diseases from July 1989 to June 2003 in a tertiary institution were collected prospectively. Perioperative outcome of patients in the first (group I) and second (group II) halves of this period was compared.

Pancreaticoduodenectomy with en bloc portal vein resection for pancreatic carcinoma with suspected portal vein involvement.

Pancreaticoduodenectomy combined with portal vein resection is increasingly accepted as a viable treatment option for pancreatic carcinoma with suspected involvement of the portal vein.However, its clinical benefit remains controversial. This study evaluated the outcomes of pancreaticoduodenectomy with portal vein resection for pancreatic carcinoma in a group of Chinese patients operated on by a specialized team in a center with a low case volume of pancreatic cancer.

Value of live donor liver transplantation experience in major hepatectomy for hepatocellular carcinoma.

Background: Live donor liver transplantation (LDLT) mandates conversance in liver anatomy and major hepatectomy. Hepatocellular carcinoma is most reliably treated by hepatectomy.

Hypothesis: The outcomes of major hepatectomy for hepatocellular carcinoma are influenced by the surgeon's LDLT experience.
