OBJECTIVE To determine the clinical features and clinical outcomes of Korean adults treated surgically for choledochal cyst. DESIGN Retrospective nationwide multicenter study. SETTING Fifteen university hospitals (tertiary care referral centers) located in all 7 Korean provinces. PATIENTS A total of 808 patients aged 18 years or older who underwent(More)
OBJECTIVE The purpose of this study was to analyze clinicopathologic and surgical features and to determine what should be an adequate extent of resection for T1 gallbladder cancers. SUMMARY BACKGROUND DATA Simple cholecystectomy offers adequate treatment for T1a cancers; however, it remains debatable whether T1b cancers should be treated by simple(More)
Studies have claimed that in the surgical treatment of pancreas body and tail cancer, radical antegrade modular pancreatosplenectomy (RAMPS) is associated with effective tangential margin and extensive lymph node dissection. In the present study, the authors have compared the surgical outcomes between RAMPS and conventional distal pancreatosplenectomy (DPS)(More)
BACKGROUND Solid pseudopapillary tumors (SPTs) of the pancreas are still considered a surgical enigma. Many clinical research trials have failed to identify prognostic factors that predict the malignant behavior of SPTs. MATERIALS AND METHODS This work was a retrospective multicenter study that included a total of 17 medical institutions. Data from 351(More)
AIM We studied to identify the clinicopathological features, treatment outcome, and prognostic factors for patients with gastrointestinal and hepatopancreaticobiliary neuroendocrine tumor (NET). METHOD Between February 2001 and May 2006, a total of 470 patients were diagnosed with NET arising from the gastrointestinal tract, pancreas, and hepatobiliary(More)
The aim of this study was to review the clinical features of primary duodenal adenocarcinoma (PDA) patients and to identify factors that influence survival. The natural history of PDA and the factors that affect patient outcome remain poorly defined. The authors reviewed the medical records of 53 patients treated for PDA from January 1995 to May 2007.(More)
There are scant studies that have analyzed the prognostic factors for malignant nonfunctioning endocrine tumors of the pancreas. We identified the predictive factors associated with long-term survival after surgical resection for malignant nonfunctioning endocrine tumors. Among the 25 patients seen at our hospital with a diagnosis of malignant(More)
OBJECTIVES The purpose of this study was to screen for genes related to lymph node metastasis by comparing the differences in the expression profile between pancreatic cancer with lymph node metastasis and one without, and to predict the invasiveness and the progression of pancreatic cancer on the basis of these findings. METHODS The total RNA of the(More)
AIM To compare outcomes from radiofrequency ablation (RFA) and hepatectomy for treatment of colorectal liver metastasis (CRLM). METHODS From January 2000 to December 2009, 408 patients underwent curative intent treatment for CRLM. We excluded patients using the criteria: size of CRLM > 3 cm, number of CRLM ≥ 5, percutaneous RFA, follow-up period < 12 mo,(More)
BACKGROUND Low resectability rate and poor survival outcomes after surgical resection for hilar cholangiocarcinoma are common in most institutions. We retrospectively reviewed the surgical outcomes of hilar cholangiocarcinoma in a tertiary institution focusing on the surgical procedures, radicalities, survival rates and independent prognostic factors.
