With the Machida Fiberduodenoscope, cannulation and opacification of pancreatic duct biliary system have been successful.
Abstract Background: Interferon (IFN) improves hepatic inflammation/fibrosis and reduces the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C (CH‐C). However, HCC develops some who have a sustained virological response (SVR) to IFN therapy. We designed this study establish follow‐up protocol for CH‐C SVR Methods: retrospectively studied 1124 received IFN. Results: developed 3.5% As compared without HCC, were predominantly male ( P =0.003), older at initiation...
Background We investigated safety-related outcomes of hepatobiliary pancreatic (HBP) surgeries performed after establishment the Japanese Society Hepato-Biliary-Pancreatic Surgery (JSHBPS) board certification system for expert surgeons. Methods analyzed post-HBP surgery mortality data obtained from annual safety reports provided by board-certified training institutions between 2012 and 2015. Results The 90-day rate 53,929 high-level HBP at was 1.7%. 30-day rates 2012, 2013, 2014, 2015 were...
To ensure that highly advanced hepatobiliary-pancreatic surgery (HBPS) is performed safely, the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHBPS) board certification system for expert surgeons established a safety committee to monitor surgical safety.We investigated postoperative mortality rates based on summary reports numbers and outcomes HBPS submitted annually by board-certified training institutions from 2012 2019. We also analyzed cases with high 90-day post-HBPS...
Abstract Background/Purpose Grade C postoperative pancreatic fistula (POPF), as defined by International Study Group of Pancreatic Fistula (ISGPF), is the most life‐threatening complication after pancreatoduodenectomy (PD). This study aims to evaluate risk factors for POPF PD. Methods a prospective, multicenter based in Japan and Taiwan. Between December 2014 May 2017, 3022 patients were enrolled this 2762 analyzed. We analyzed on updated 2016 ISGPF scheme (organ failure, reoperation, and/or...
Combination therapy with adefovir dipivoxil (ADV) and lamivudine (LAM) is recommended for patients infected LAM-refractory hepatitis B virus (HBV). However, the effects of such on renal function serum phosphorus levels have not been fully evaluated. ADV LAM was given to 37 HBV, including 17 hepatic cirrhosis. Serum HBV DNA decreased below 2.6 log(10) copies/mL in 23 (62%) at 12 months, 25 (78%) 32 24 16 (84%) 19 36 months. Except one cirrhotic patient, alanine aminotransferase were 50 IU/L...
An undifferentiated carcinoma with osteoclast‑like giant cell tumors (UC‑OGC) is a rare type of tumor, which predominantly occurs in the pancreas. Due to rarity UC‑OGC, sufficient clinical data are not available and its prognosis following surgical resection remains unclear. In current report case 37‑year‑old female presented, whom an UC‑OGC pancreas was removed this, second remnant during procedure. At patient's initial admission, preoperative images demonstrated well‑demarcated mass marked...
Background and study aims Biliary plastic stents are generally substituted for gallbladder in endoscopic transpapillary stenting (EGBS), there is no sufficient evidence about what type of stent suitable. We examined outcomes EGBS using standard biliary a novel acute cholecystitis evaluated the efficacy stent. Patients methods Seventy patients with whom was performed were retrospectively. 23 (novel group) 47 (pigtail: 35, straight: 12) (control group). In two groups, we EGBS. Results There...
Abstract Background Pancreatic trauma is reportedly associated with high morbidity and mortality. Main pancreatic duct (MPD) injury critical for treatment. Methods As a study project of the Japanese Society Abdominal Emergency Medicine (JSAEM), we collected data 163 patients who were diagnosed treated at JSAEM board‐certified hospitals from 2006 to 2016. Clinical backgrounds, diagnostic approaches, management strategies, outcomes evaluated. Results Sixty‐four (39%) as having MPD that...
Evidence regarding the incidence and clinical outcome of cystic duct perforation (CDP) during endoscopic transpapillary gallbladder drainage (ETGBD) is inadequate. The present study aimed to evaluate management CDP ETGBD.Between March 2011 December 2019, 249 patients underwent initial ETGBD for acute cholecystitis. was retrospectively examined outcomes between non-CDP groups were compared.CDP occurred in 23 (9.2%) (caused by guidewire 15 cannula 8). successful 10 following CDP. In 13 who...
Enhanced recovery after surgery (ERAS) protocols are beneficial for pancreatoduodenectomy (PD). Our aim was to evaluate risk factors associated with ERAS protocol failure PD.Clinical variables of 187 patients managed using between April 2011 and 2017, including non-early (non-ER) patients, complications or requiring a hospital stay ≥15 days, early (ER) were compared. A physical aging (PA) score devised predict postoperative risks.Independent pre-albumin level ≤18 mg/dl (odds ratio (OR)...
<i >Aims</i>. To evaluate the need for endoscopic sphincterotomy (EST) before covered self-expandable metal stent (CSEMS) deployment malignant lower biliary stricture with pancreatic duct obstruction. >Methods</i>. This study included 79 patients who underwent CSEMS unresectable Treatment outcomes and complications were compared between 38 EST (EST group) 41 without (non-EST group). >Results</i>. The technical success rates 100% in both non-EST group. incidence of pancreatitis was...
Objective: To investigate the influence of endoscopic gallbladder stenting (EGBS) on subsequent cholecystectomy. We retrospectively compared surgical outcomes EGBS, followed by elective cholecystectomy with those immediate (IC). Patients and Methods: A total 503 patients were included in this study. who underwent EGBS as initial treatment for acute cholecystitis, cholecystectomy, group IC during hospitalization group. Propensity score matching analysis was used to compare outcomes. In...
This study aimed to investigate whether preoperative muscle mass is associated with the recurrence of distal cholangiocarcinoma after pancreatoduodenectomy (PD).We retrospectively examined 88 patients who had undergone PD for cholangiocarcinoma. The psoas index (PMI) was measured using computed tomography as an mass. We performed multivariate analysis factors influencing early and developed a prognostic survival model independent risk recurrence.The cut-off PMI values within 1 year surgery,...
Endoscopic retrograde cholangiopancreatography (ERCP) is technically more challenging in patients who have undergone gastrointestinal (GI) reconstruction.The aim of this study was to evaluate the utility anterior oblique-viewing endoscope (AOE) for ERCP with a retained major duodenal papilla after GI reconstruction.This retrospective involving 40 (50 procedures) reconstruction underwent using AOE. Reconstruction consisted Billroth II gastrectomy (BII) 25 (30 and Roux-en-Y anastomosis (RY) 15...
Background/Aims. In early endoscopic retrograde cholangiopancreatography (ERCP) for acute cholangitis due to choledocholithiasis, it is unclear that single-session stone removal can be safely performed. We examined the efficacy and safety of mild-to-moderate associated with choledocholithiasis. Methods. Among patients choledocholithiasis who underwent ERCP (n = 167), we retrospectively compared group (patients removal; n 78) drainage biliary alone; 89) effectiveness by ERCP. Results. The in...
Abstract Background Gallbladder cancer (GBC) with liver metastasis is considered unresectable. However, there have been infrequent reports of long-term survival in patients GBC and metastases. Therefore, we examined the characteristics survivors gallbladder metastasis. Methods A retrospective multicenter study 462 (mean age, 71 years; female, 51%) was performed. Although pre-operatively diagnosed were generally excluded from resection, some cases identified during surgery resected. Result In...

Goals: This study assessed feasibility novel EP purpose reliable post-EP stenting. Study: We conducted prospective pilot involving 10 consecutive with tumor major duodenal papilla. developed stent, which attached suture, and devised method by first placed at an...
Background: Endoscopic transpapillary gallbladder drainage (ETGBD) for acute cholecystitis (AC) after self-expandable metal stent (SEMS) placement is technically challenging and there are no reports about its outcome in a several cases. This study aims to assess the outcomes of ETGBD AC SEMS placement. Methods: Between April 2011 2019, 314 patients underwent biliary stricture. Among them, 12 21 who developed ETGBD. In general, was performed removal cases which covered previously placed or...
