AbstractAbstract PDFPubReaderePub
We report a rare case of gastric cancer presenting with a gastrocolic fistula during ramucirumab and paclitaxel combination therapy that was successfully managed with colonic stenting. A 75-year-old man was admitted to our hospital with the chief complaint of melena. Esophagogastroduodenoscopy revealed a large ulcerated tumor in the lower stomach, judged by laparoscopy as unresectable (sT4bN1M0). After four cycles of first-line chemotherapy with S-1 plus oxaliplatin, the patient showed disease progression, and second-line therapy with ramucirumab and paclitaxel was started. At the end of the third cycle, the patient had gastric antral stenosis, which necessitated the placement of a gastroduodenal stent. When the patient complained of diarrhea 10 days later, esophagogastroduodenoscopy revealed a fistula between the greater curvature of the stomach and the transverse colon. The fistula was covered by double colonic stenting, with a covered metal stent placed within an uncovered metal stent, after which leakage from the stomach to the colon stopped.

Background
/Aims: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studies have reported conflicting associations between duodenal tumor development and Helicobacter pylori infection or endoscopic gastric mucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopic gastric mucosal atrophy.
Methods
This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopic or surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophy and the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies at two of the seven participating institutions.
Results
For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected (p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%) control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent risk factor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44–8.40; p<0.001).
Conclusions
Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

AbstractAbstract PDFPubReaderePub
A 43-year-old man with rheumatic arthritis was admitted to our hospital for symptoms of cough, left chest pain, and left elbow pain, and further examination revealed an elevated level of C-reactive protein. On day 2 after admission, he underwent esophagogastroduodenoscopy. On the morning of day 7, he developed a high fever of 39.7°C, several hours after bronchoscopy. On day 13, he underwent colonoscopy. Five minutes after the colonoscopy, he developed a high fever of 39.9°C, accompanied by stridor, indicating a decrease in arterial oxygen saturation level. An intradermal test for peracetic acid which was used for cleaning flexible endoscopy was positive. We suspect that he suffered from an allergic reaction to peracetic acid following the flexible endoscopy. This is the first case reported on suspicious allergic reaction to peracetic acid following a flexible endoscopy procedure.
