We report the case of diffuse large B-cell lymphoma (DLBCL) with a fistula from the ileum to the cecum. A 57-year-old male came to the hospital complaining of abdominal pain. He underwent an abdominal computed tomography with contrast, which showed full-thickness wall thickening at the ileocecal region. He underwent a lower gastrointestinal endoscopy. No tumor was found at the ileocecal valve, and macroscopic findings were normal. The scope was advanced to the cecum, an additional outpouching was found. The outpouching appeared to be an ileocecal fistula. The diagnosis was DLBCL. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate whether a novel, easy loop-forming guidewire could reduce post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) in patients undergoing endoscopic nasopancreatic drainage tube placement for serial pancreatic juice aspiration cytologic examination (SPACE)., Methods: We evaluated patients with suspected pancreatic cancer who underwent SPACE at our institution between January 2015 and April 2023 retrospectively. The patients were divided into 2 groups based on the type of guidewire used, namely, easy loop-forming and control groups. Propensity score matching was used to compare the incidence of PEP between the groups., Results: We included 101 patients, with 51 and 50 in the easy loop-forming and control groups, respectively. After propensity score matching, 29 pairs of patients were selected from each group. Intraductal ultrasonography of the pancreas was performed more frequently in the easy loop-forming group than in the control group (27.6% vs 0%; P = 0.004); however, PEP incidence was significantly lower in the easy loop-forming group than in the control group (3.4% vs 27.6%; odds ratio, 0.097; 95% confidence interval, 0.002-0.82; P = 0.025)., Conclusions: The use of the novel easy loop-forming guidewire decreased PEP occurrence in patients who underwent endoscopic nasopancreatic drainage tube placement for SPACE., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

The patient was a 48-year-old woman, admitted for pleural effusion detected on chest X-ray in July 2005. Computer tomography(CT)scan showed massive pericardial and pleural effusion. We performed pericardial drainage, and the cytological diagnosis of the pericardial effusion was class V. Because endoscopic examination revealed advanced gastric cancer, we diagnosed it as gastric cancer complicated with carcinomatous pericarditis. The serum tissue polypeptide antigen(TPA) level was markedly elevated. In August 2005, we started combination chemotherapy using oral S-1(100mg/body/day; day 1- 21)and intravenous CDDP(100mg/body/day; day 8)for 5 weeks. After 2 courses, TPA was reduced and pericardial effusion disappeared. However, after 3 courses, pericardial effusion recurred. We changed treatment to weekly docetaxel. After 2 courses, we changed it to paclitaxel/CDDP. However, TPA was increased and pleural effusion and dyspnea occurred. There- fore, we changed to a course of combination chemotherapy using oral S-1(100mg/body/day; day 1-14)and intravenous CPT-11(100mg/body/day; day 1 and 8)for 4 weeks from March 2006. After 10 courses, we were unable to control pleural effusion, and dyspnea recurred. She died in December 2006. Gastric cancer complicated with carcinomatous pericarditis has a poor prognosis, but systemic chemotherapy mainly with S-1 was effective.
