Professor In Woong Han's research lab specializes in surgical oncology and pancreatic surgery, with a strong focus on improving outcomes in pancreatic and biliary tract malignancies. The lab investigates perioperative risk factors, particularly fluid management and postoperative complications like pancreatic fistula, using clinical data and artificial intelligence for predictive modeling. Research also emphasizes prognostic biomarkers—such as ceruloplasmin—and risk stratification tools for pancreatic cystic neoplasms, aiming to enhance preoperative decision-making and personalized treatment strategies.
Figures are computed from collected data and may differ slightly.
Pros and cons were well balanced between the two groups. Decisions on the timing of cholecystectomy after PTGBD should be made based on considerations of patient condition, hospital facilities, and surgical experience.
This study is the first to predict POPF with multiple risk factors using AI. This platform is reliable (AUC 0.74), so it could be used to select patients who need especially intense therapy and to preoperatively establish an effective treatment strategy.
Both o-FRS and a-FRS might reflect CR-POPF incidence, but some risk factors had no or low statistical significance. Further research is needed to revise the FRS.
Although histological subtypes are associated with the degree of dysplasia, histological subtypes have limited prognostic value for pancreatic IPMNs.
Recent studies on perioperative fluid administration in patients undergoing pancreaticoduodenectomy (PD) have suggested that increased fluid loads are associated with worse perioperative outcomes. The purpose of this study was to investigate the relationship between intraoperative fluid (IOF) administration and postoperative pancreatic fistula (POPF), and to determine additional risk factors affecting pancreatic fistula in patients undergoing PD.From 2005 to 2014, a total of 182 patients with va
Ceruloplasmin is supposed to be related with advanced T stage and perineural invasion, having a possibility as a candidate prognostic marker for bile duct cancer.
We recommend the criteria of CIR as bile duct variation type, length of hilum to contralateral second bile duct confluence, and extent of tumor infiltration over the second confluence for Bismuth type IV HCCA.
The clinicopathologic findings of duodenal GIST differ from those of small intestinal GIST. Patients with duodenal GIST have a worse prognosis than those with small intestinal GIST. Aggressive treatment including surgical resection should be considered for duodenal GIST, even if the risk is relatively low.
The 8th American Joint Committee on Cancer (AJCC) staging system for distal cholangiocarcinoma (DCC) included a positive lymph node count (PLNC), but a comparison of the prognostic predictive power of PLNC and lymph node ratio (LNR) is still under debate. This study aimed to compare various staging models made by combining the abovementioned factors, identify the model with the best predictive power, and propose a modified staging system. We retrospectively reviewed 251 patients who underwent su
