RESUMEN
Acute recurrent pancreatitis (ARP) is a clinical condition characterized by repeated episodes of acute pancreatitis. In this case study, a 62-year-old man was diagnosed with mild pancreatitis five years ago, with alcohol intake initially considered the cause. Since then, he experienced three episodes of pancreatitis despite ceasing alcohol consumption completely. Consequently, the patient was diagnosed with ARP. Various diagnostic and imaging tests were performed to determine the etiology of his condition, including blood tests, magnetic resonance cholangiopancreatography, endoscopic ultrasonography, and contrast-enhanced computed tomography. The results were inconclusive; however, endoscopic retrograde cholangiopancreatography revealed the reflux of bile and pancreatic juice into the alternative ducts, despite the absence of anatomical abnormalities in the biliary tract or pancreatic duct. These findings subsequently led to the diagnosis of biliopancreatic reflux, which activated pancreatic enzymes causing ARP. Endoscopic biliary sphincterotomy was performed to alleviate the patient's symptoms. One year later, the patient remained symptom-free. This case highlights the importance of examining bile and pancreatic juice components before considering endoscopic sphincterotomy in patients with unexplained ARP.

The prevalence of chronic diarrhea in the general population is reported to be 4%-5%. Since various pathological conditions cause diarrheal symptoms, etiological diagnosis of chronic diarrhea is difficult in many cases. Medical history taking, physical examinations, and laboratory testing are not adequately sensitive or specific, thus a colonoscopic investigation is frequently employed for etiological evaluation. However, for cases with non-bloody chronic diarrhea, the diagnostic yield of a colonoscopy procedure is reported to be not high enough. Furthermore, endoscopically identifiable findings are not adequately specific for the diagnosis of diarrheal disease, except for inflammatory bowel disease, while microscopic colitis, amyloidosis, eosinophilic gastroenteritis, celiac disease, and bile acid diarrhea are difficult to definitively diagnose using endoscopic findings. Thus, a histopathological examination of biopsy samples obtained with endoscopy is critically important. Endoscopists should consider obtaining biopsy samples from even normal-appearing gastrointestinal mucosa for chronic diarrhea diagnosis.
RESUMEN
Patients with coronavirus disease 2019 exhibit various gastrointestinal symptoms. Although diarrhea is reported in many cases, the pathophysiology of diarrhea has not been fully clarified. Herein, we report a case of coronavirus disease 2019 with diarrhea that was successfully relieved by the administration of a bile acid sequestrant. The patient was a 59-year-old man whose pneumonia was treated by the administration of glucocorticoids and mechanical ventilation. However, beginning on the 30th hospital day, he developed severe watery diarrhea (up to 10 times a day). Colonoscopy detected ulcers in the terminal ileum and ascending colon. The oral administration of a bile acid sequestrant, colestimide, improved his diarrhea quickly. Ileal inflammation is reported to suppress expression of the gut epithelial apical sodium-dependent bile acid transporter. It decreases bile acid absorption at the distal ileum and increases colonic delivery of bile acids, resulting in bile acid diarrhea. In summary, the clinical course of the case presented in this report suggests that bile acid diarrhea is a possible mechanism of watery diarrhea observed in patients with coronavirus disease 2019.

A 76-year-old man presented to our hospital with continuous abdominal pain and vomiting. The results of the computed tomography indicated a pancreatic head mass with multiple liver metastatic tumors. Multiple liver tumors progressed rapidly, and the patient died of the resulting acute hepatic failure approximately 1 month after the onset of symptoms. The results of the postmortem examination indicated anaplastic pancreatic carcinoma (pleomorphic type) with multiple liver metastases. The tumor cells in the primary pancreatic lesion and liver metastases were replaced with normal tissue, and they showed a decrease in stainability by E-cadherin staining. Overall, the pathological findings suggested that the inhibition of E-cadherin may be related to the proliferation and infiltration of anaplastic cancer cells.

BACKGROUND Bouveret syndrome is a rare complication of cholelithiasis that often leads to symptoms of gastric outlet obstruction. CASE REPORT An 84-year-old woman developed acute abdominal symptoms due to impaction of a gallstone in the horizontal part of the duodenum. The diagnosis was supported by abdominal computed tomography and double balloon endoscopy. Considering her advanced age and the position of the calcified gallstone, we decided to perform electrohydraulic lithotripsy using double balloon endoscopy for treatment. Finally, the impacted stone was removed with reduced size. She was discharged home 10 days after admission without recurrence. CONCLUSIONS This case illustrates that electrohydraulic lithotripsy using double balloon endoscopy is very effective, especially for treatment of Bouveret syndrome caused by gallstone impaction in the horizontal part of the duodenum.

BACKGROUND: Hepatocellular adenoma (HCA) is a rare liver tumor that has the potential for rupture and malignant transformation. Here, we report a case of multiple hepatocellular adenomas (HCAs) that were treated by surgical resection. CASE PRESENTATION: An 18-year-old man was admitted to our hospital with proteinuria. His height was 176.5 cm, weight was 126 kg, and body mass index was 40 kg/m2. A liver tumor was incidentally found on abdominal ultrasonography. Contrast-enhanced computed tomography and gadoxetic acid-enhanced magnetic resonance imaging revealed three hepatic tumors that were 68 mm, 16 mm, and 9 mm in segments 3/4, 8, and 1, respectively. A percutaneous needle biopsy of the largest tumor was performed, the diagnosis of unclassified type HCA was made, and laparoscopic partial liver resection was performed of all three. The postoperative course was uneventful, and the patient was discharged 12 days later. An immunohistochemical examination revealed positivity for serum amyloid A protein, no decrease in fatty acid-binding protein, and negativity for ß-catenin, glutamine synthetase, and cytokeratin 7. Therefore, these tumors were diagnosed as inflammatory type HCAs. CONCLUSIONS: We reported an extremely rare case of multiple resected HCAs in a young, obese Japanese man. Our findings suggest that HCA should be considered in the differential diagnosis of liver tumor in obese patients. Further studies that consider clinical and molecular risk factors are required to establish individualized treatment plans for HCA in obese patients.
RESUMEN
BACKGROUND Adenomatous polyposis coli is an autosomal dominant hereditary disorder. Duodenal adenocarcinoma and adenoma, which are extracolonic lesions, not only affect the prognosis of patients but also cause acute pancreatitis. CASE REPORT We present the case of a 73-year-old male. He had undergone proctocolectomy for familial adenomatous polyposis and distal gastrectomy (Billroth II reconstruction with Braun anastomosis) for gastric ulcer; he presented with acute pancreatitis caused by ampullary duodenum adenoma. Double-balloon endoscopy showed 2 adenomatous polyps in the major papilla and descending limb of the duodenum. Based on the findings of endoscopy and biopsy, the duodenal polyps were diagnosed as adenomas and classified as Spigelman stage II. CONCLUSIONS Our case report suggests that duodenal surveillance is necessary for patients with adenomatous polyposis coli. In addition, surveillance using double-balloon endoscopy is useful for patients with an altered gastrointestinal anatomy.

A 78-year-old woman was found to have gallbladder wall thickening on ultrasonography during a routine health check-up and was referred to our clinic. On contrast-enhanced endoscopic ultrasonography, a papillary lesion measuring 14mm was detected in the fundus, which showed a heterogeneous enhancement at the early phase. She underwent cholecystectomy and gallbladder bed resection. Histological examination revealed that the tumor consisted of mucinous atypical cells, regularly arranged in a high-papillary architecture with delicate fibrovascular cores, which led to the diagnosis of intracholecystic papillary neoplasm of the gallbladder.

A 73-year-old man visited our hospital for consultation regarding a pancreatic tumor. Abdominal computed tomography, magnetic resonance imaging, and endoscopic ultrasound scan (EUS) revealed tumor 2 cm in diameter located in the pancreatic tail. EUS-guided fine needle aspiration (EUS-FNA) suggested pancreatic mixed acinar-endocrine carcinoma, and he underwent distal pancreatectomy. Few reports exist where preoperative EUS-FNA suggested pancreatic mixed acinar-endocrine carcinoma; thus, we report this case.
