Abstract null null Background and Aims null Endoscopic ultrasound-guided through-the-needle biopsy (EUS-TTNB) using microbiopsy forceps is performed for the accurate diagnosis of pancreatic cystic lesions (PCLs). However, there are no standardized protocols for this procedure, and the amount of data on its efficacy is limited. Here, we evaluated the feasibility, efficacy, and safety of EUS-TTNB in categorizing the types of PCLs, and identified the factors associated with diagnostic failure. null...

Abstract null null Background null Retroperitoneal neurogenic tumors are extremely rare pathological entities; therefore, few clinical features and natural courses, especially originating from the pancreatic/peripancreatic regions, have been reported. This study aimed to investigate the clinicopathological features of pancreatic and peripancreatic neurogenic tumors and assess the diagnostic value of computed tomography (CT) and endoscopic ultrasound-guided fine needle biopsy (EUS-FNB). null null...

Background and aims null Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is frequently used for the preoperative histologic diagnosis of pancreatic cancer. However, debate continues regarding the clinical merits of preoperative EUS-FNA for the management of resectable pancreatic cancer. We aimed to evaluate the benefits and safety of preoperative EUS-FNA for resectable distal pancreatic cancer. null Methods null The medical records of 304 consecutive patients with suspected distal ...

Background Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has been increasingly used for the management of various solid pancreatic tumors. This study aimed to evaluate the feasibility and safety of EUS-RFA for serous cystic neoplasms (SCNs). Methods 13 patients with microcystic SCNs with honeycomb appearance underwent EUS-RFA using a 19-gauge RFA needle. Before ablation, cystic fluid was aspirated until a thin layer of fluid remained. Results EUS-RFA was successful in all patien...

Despite development in endoscopic treatment and minimally invasive surgery for choledocholithiasis, there remains a small number of patients who require bypass Roux-en-Y choledochojejunostomy (RYCJ) because of the intractable occurrence of common bile duct (CBD) stones. We herein present the detailed procedures of open RYCJ customized for intractable choledocholithiasis. The first method is a side-to-end choledochojejunostomy with intraluminal closure of the distal CBD. This method was applied t...

PURPOSE This study evaluated the efficacy of adjuvant chemotherapy (AC) in patients with resected ampulla of Vater (AoV) carcinoma. Materials and Methods Data from 646 patients who underwent surgical resection at Asan Medical Center between 2000 and 2017 were retrospectively reviewed. RESULTS The median age of the patients was 62 years, and 54.2% were male. Patients were classified into AC group (n=165, 25.5%) and no AC group (n=481, 74.5%). With a median follow-up duration of 88 months, in pati...

Introduction For unresectable hilar obstruction, restoring and maintaining biliary ductal patency are crucial for improved survival and quality of life. The endoscopic placement of stents is now a mainstay of its treatment, and bilateral stenting is effective for biliary decompression. This study aimed to determine the clinical outcomes of bilateral metal stent placement using large cell-type stents and the clinical predictors of stent dysfunction in patients with malignant hilar obstruction. Me...

BACKGROUND Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) and fine-needle biopsy (FNB) are the current standard of care for sampling pancreatic and peripancreatic masses. Recently, a 22G EUS-FNB needle with Franseen geometry was developed, and this device was also introduced in a 25G platform. We compared the performance of the 25G and 22G Franseen needles for EUS-guided sampling of pancreatic and peripancreatic solid masses. METHODS We conducted a parallel-group randomized non-...
