PURPOSE Laparoscopic distal pancreatectomy (LDP) is a well-accepted procedure for benign and malignant diseases of the pancreatic body and/or tail. To perform it safely, a wide operative field is crucial. For the maintenance of a good surgical field during LDP, we developed an original technique for stomach retraction: "Complete REtraction of the StomaCh using pEnrose draiN and liver reTractor, CRESCENT." METHODS In CRESCENT technique, the body and antrum of the stomach are suspended by two Penr...

BACKGROUND 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 Grade C POPF after PD. METHODS This is a prospective, multicenter study based in Japan and Taiwan. Between December 2014 and May 2017, 3,022 patients were enrolled in this study and 2,762 patients were analyzed. We analyzed risk factors of Grade C ...

Abstract Background Several studies comparing internal and external stents have been conducted with the aim of reducing pancreatic fistula after PD. There is still no consensus, however, on the appropriate use of pancreatic stents for prevention of pancreatic fistula. This multicenter large cohort study aims to evaluate whether internal or external pancreatic stents are more effective in reduction of clinically relevant pancreatic fistula after pancreaticoduodenectomy (PD). Methods We reviewed 3...

Objectives The objective of this study was to clarify the role of pancreatectomy for patients with resectable and borderline resectable pancreatic ductal adenocarcinoma aged 80 years or older using a nationwide audit by the Japan Pancreas Society. Methods Data were collected from 39 institutions from 2007 to 2014. The primary endpoint was overall survival, and secondary endpoints were surgical outcomes and predictive factors for prognosis. Results Data were obtained from 556 octogenarians who un...

BACKGROUND/AIM This study investigated the feasibility of an integrated scoring system of preoperative prognostic parameters using data from before/after neoadjuvant therapy in patients with borderline resectable pancreatic cancer (BRPC). PATIENTS AND METHODS We constructed and analyzed a prognostic scoring system using factors that were previously reported to be significant prognostic indicators or predictors of histological response. RESULTS We analyzed 28 consecutive patients with BRPC who un...

BACKGROUND/AIM The efficacy of pembrolizumab for intrahepatic cholangiocellular carcinoma (IHCCC) is not widely reported. CASE REPORT We began pembrolizumab treatment in a 69-year-old male with recurrent IHCCC at 18 months after his surgery because of the proven microsatellite instability (MSI)-high status. The patient had partial response, with an 82.5% reduction at the end of 18 courses. Immunostaining of the primary tumor revealed intra-tumoral infiltration of both PD-1+ and CD8+ T cells, and...

BACKGROUND Peritoneal metastasis of hepatocellular carcinoma (HCC) is rare. We investigated patients who underwent peritoneal metastasectomy in a multicenter study in Japan. METHODS The study included 92 patients with HCC who underwent resection for peritoneal metastasis between January 2007 and December 2013. We investigated background and operative factors, as well as overall and recurrence-free survival rates. Patients were classified according to the extent of peritoneal metastasis using the...

BACKGROUND Administration of landiolol hydrochloride was found to be associated with reduced incidence of atrial fibrillation (AF) after esophagectomy for esophageal cancer in our previous randomized controlled trial (RCT). In addition, reduced incidence of AF was associated with reduction of other complications. Meanwhile, the effects of postoperative AF and other complications on long-term survival following esophagectomy are not well understood. MATERIALS AND METHODS Between March 2014 and Ja...

Abstract Background Coronavirus Disease (COVID-19) is a growing concern worldwide. About 5% of COVID-19 cases require intensive care. However, the optimal treatment for respiratory failure in COVID-19 patients is yet to be determined. Case presentation A 79-year-old man with severe acute respiratory distress syndrome due to COVID-19 was admitted to our intensive care unit. Prone ventilation was effective in treating the patient?s hypoxemia. Further, the patient received lung protective ventilati...
