A 26-year-old man with a history of ulcerative colitis treatment presented to our clinic with abdominal pain and fever. He had a history of bloody stools and abdominal pain at 19 years of age. A thorough examination by a medical practitioner, including lower gastrointestinal endoscopy, resulted in the diagnosis of ulcerative colitis.

Gastrocolic fistula caused by transverse colon cancer: a case report.

Background: A gastrocolic fistula is an unusual communication between the colon and the stomach. Although colon cancer is the most common malignant cause of gastrocolic fistula in the Western world, the incidence of gastrocolic fistula due to colon cancer is 0.3% in operated cases.

Aspiration pneumonia associated with achalasia.

In this case, a chest computed tomography scan of a young patient with pneumonia revealed esophageal obstruction, which led to the diagnosis of aspiration pneumonia due to achalasia. This report highlights achalasia and other gastrointestinal obstructions as one of the causes of aspiration pneumonia.

Serotonin-positive neuroendocrine neoplasm with pancreatic ductal dilation in which cytological immunostaining contributed to the diagnosis.

A 52-year-old man was transported via an ambulance because of syncope and the passage of tarry stools, which had been noted the previous day. He was diagnosed with upper gastrointestinal bleeding from a gastric ulcer and underwent endoscopic hemostasis. Prior to endoscopy, abdominal computerized tomography performed for gastrointestinal bleeding revealed pancreatic duct dilation.

Spontaneous retroperitoneal bleeding secondary to celiac artery compression syndrome.

Clinicians should consider celiac artery compression syndrome as the cause of ruptured visceral aneurysm and dissection and ask patients for unexplained chronic abdominal symptoms. Endovascular embolization with metallic coil placement is the first-line treatment, and surgery can be avoided in some cases.

Small bowel obstruction of barium for gastric cancer screening.

We report a case of small bowel obstruction without perforation and peritonitis caused by inspissated barium sulfate for gastric cancer screening and surgically treated 26 hours after the onset of abdominal pain.

Pancreatic panniculitis in a patient with pancreatic adenosquamous carcinoma.

Pancreatic panniculitis is a rare complication of pancreatic diseases. We aimed to evaluate a case of pancreatic panniculitis. A 58-year-old woman was referred to our hospital with complaints of painful cutaneous nodules on her limbs.

Ceftriaxone pseudolithiasis detected by computed tomography and followed up until resolution.

Ceftriaxone is a third-generation cephalosporin antibiotic that has been widely used to treat various infectious diseases. We report a case of ceftriaxone pseudolithiasis that was detected by computed tomography (CT) and followed up until it was resolved. A 76-year-old woman with diabetes mellitus and renal impairment, but no history of gallstones, was diagnosed with septic shock due to renal and lung abscesses and treated with ceftriaxone.

Balloon-Occluded Trans-Arterial Chemo-Embolization Technique with Repeated Alternate Infusion of Cisplatin Solution and Sparse Gelatin Slurry (RAIB-TACE) for Large Hepatocellular Carcinoma Nodules More than 7 cm in Diameter.

Objective: It is sometimes difficult to obtain complete/partial response of large hepatocellular carcinoma (HCC) nodules by trans-arterial chemoembolization/embolization (TACE/TAE). The aim is retrospective investigation of tumor response of large HCC nodules (>7 cm) treated by the new TACE technique, repeated alternate infusion of cisplatin solution, and sparse gelatin slurry under balloon occlusion (RAIB-TACE). .

Preoperative histological subtype classification of intraductal papillary mucinous neoplasms (IPMN) by pancreatic juice cytology with MUC stain.

Objective: To prospectively evaluate the diagnostic value of preoperative histological subtyping of intraductal papillary mucinous neoplasms (IPMNs) by pancreatic juice cytology (PJC) with mucin (MUC) stain.

Background: IPMNs are classified into four subtypes based on their histomorphology and mucin phenotype, and varied degrees of malignant nature and prognosis among these subtypes have been shown.

Methods: The subjects were 36 patients with surgically confirmed IPMNs, who underwent PJC preoperatively by endoscopic retrograde cholangiopancreatography.

Extensive endothelial replacement by tumor cells in the portal system: an autopsy case of intrahepatic cholangiocarcinoma.

For these cases, we tried endoscopic papillary balloon dilatation, and as a result knoches were made. And after the disappearance of the knoch, we could easily remove the stone.

Spindle and giant cell type undifferentiated carcinoma arising in the common bile duct: a case report.

In this study, we investigated the usefulness of PEG in home health care from the view point of cost effectiveness.
