The risk of pancreatic cancer is also reported to be higher in patients with PBM compared to the general population; the underlying cause remains unclear. We report a 73-year-old man with widespread pancreatic cancer involving the entire pancreas. The patient previously underwent curative resection for gallbladder cancer and hilar cholangiocarcinoma concomitant with PBM. A total pancreatectomy was performed for the new pancreatic lesion. Histopathological examination revealed a papillary tumor predominantly composed of intraepithelial lesions that extended throughout the pancreatic duct, with skip lesions and irregular invasive foci at multiple sites within the duct. The morphological features and mucin profile were similar to those of the previous biliary lesions. Genetic analysis of the current lesion showed wild-type KRAS, GNAS, and PIK3CA genes consistent with the previous lesions, indicating that the pancreatic and biliary lesions were molecularly identical clones. Based on the clinicopathological findings and molecular analysis, we concluded that the BTC had spread intraluminally to the pancreatic duct through the common channel of the PBM, resulting in intraductal dissemination. Patients with PBM should be followed for pancreatic lesions, because of the risk of intraductal dissemination of BTC.","PeriodicalId":10364,"journal":{"name":"Clinical Journal of Gastroenterology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When pembrolizumab was administered, the tumor shrinkage effect was rapidly observed, which was sustained even after 30 months. No pathogenic mutations were observed in the germline test, and MSI-high was considered to be due to the MLH1 pathogenic mutation occurring sporadically in somatic cells. MSI-H intrahepatic cholangiocarcinoma is extremely rare.

Less than 200 cases have been reported worldwide, and standardized treatment guidelines have not yet been established. A 72-year-old man presented with abdominal distension, diarrhea, and appetite loss. Contrast-enhanced abdominal computed tomography revealed a 5 cm mass in the pancreatic tail with multiple feeding and draining vessels, a portosystemic shunt, and moderate ascites, suggesting a P-AVM. Endoscopic ultrasonography revealed a hypoechoic area in the pancreatic tail measuring 50 mm in diameter. Esophagogastroduodenoscopy revealed F2-type esophageal varices. Based on imaging findings and clinical history, the patient was diagnosed with P-AVM, and Osler-Weber-Rendu disease was excluded. Initial treatment with transarterial embolization was attempted, but proved insufficient due to high blood flow and multiple feeders. Surgical resection via distal pancreatectomy was subsequently performed to alleviate portal hypertension and resolve abdominal symptoms, although significant intraoperative bleeding occurred. This case highlights the diagnostic and therapeutic challenges of P-AVMs, particularly in high-flow lesions with complex vascular anatomy. Surgical resection remains the definitive treatment for symptomatic P-AVM and effectively resolves the associated complications.

Blood tests revealed chronic hepatitis B, and nucleoside analog therapy with entecavir was initiated before the sarcoidosis diagnosis. A liver biopsy confirmed sarcoidosis, and treatment continued without steroid use. Significant improvement in symptoms and tumor size reduction were observed within weeks. After 6 months of treatment, positron emission tomography/computed tomography showed further regression of the liver and spleen tumors, with no symptom recurrence. Given the rarity of sarcoidosis complicated by chronic hepatitis B, this case suggests that controlling hepatitis B virus infection with nucleos(t)ide analogs might improve sarcoidosis symptoms without steroid use.

There is still no consensus on the surgical treatment of small bowel strictures with suspected CD-associated SBA. We report a case of small bowel high-grade dysplasia and two cases with advanced SBA. Case 1 involved a 53-year-old man whose high-grade dysplastic lesion of the small intestine was discovered incidentally postoperatively and successfully resected curatively.

Additionally, a pancreatic spontaneous dislodgment stent (PSDS) was inserted to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis. Cholecystitis resolved, and the patient was discharged seven days later. Twenty-five days after ETGBD, she experienced abdominal pain, and computed tomography revealed ascending colon perforation by the migrated PSDS.

The postoperative course was uneventful, and colonoscopy performed two months after surgery revealed multiple diverticula in the ascending colon. PSDS-induced gastrointestinal perforations are extremely rare. Previous case reports have suggested that perforation is caused by long-term stent retention in the gastrointestinal tract due to obstructions, such as peritonitis carcinomatosa or postoperative adhesions. We believe that in this case, the PSDS was retained because of multiple colonic diverticula.
