    In order to improve the diagnostic accuracy and treatment strategy for small bowel obstruction, we developed a non-emergency small bowel obstruction scoring system (0-4). We performed a retrospective analysis on 94 patients diagnosed with mechanical small bowel obstruction at our hospital. Anterior adhesion, small bowel feces sign, scoring system, and the usefulness of small bowel feces subtypes were examined. When the non-emergency small bowel obstruction scores 3-4, 99% were non-emergency obstructions, with the exclusion of strangulated small bowel obstruction. On the contrary, when the non-emergency small bowel obstruction scores 0-1, 47.5% were strangulated small bowel obstruction. As the effectiveness of withholding food and fluids (NPO) or short tube is high (about 70%) when small bowel feces are dry, placing a long tube may not be needed.

    A man in his 60s was hospitalized with multiple cerebral infarctions and referred for Trousseau's syndrome. Computerized tomography confirmed a 60-mm mass in the pancreatic head and swollen lymph nodes around the abdominal aorta. Fine needle aspiration cytology of the pancreatic lesion and laparoscopic para-aortic lymph node biopsy revealed adenocarcinoma, including clusters of invasive micropapillary carcinoma (IMPC). Chemotherapy (gemcitabine and nab-paclitaxel) markedly decreased the primary and metastatic lesions, and no recurrence was clinically detected 24 months later. To the best of our knowledge, reports of pancreatic IMPCs are rare. Our case was the seventeenth case of pancreatic cancer with IMPC. In this case, chemotherapy was markedly effective.

    A 36-year-old man who complained of epigastric pain was transferred to the emergency room. We performed contrast enhanced computed tomography (CT) but were unable to confirm a diagnosis at that time. Because this patient had symptoms of gallbladder inflammation following hospitalization, we reviewed the CT images. We found luminal obstruction between the celiac artery and proper hepatic artery due to celiac artery dissection in the images. Gangrenous cholecystitis was suspected based on the findings;therefore, the patient underwent emergency cholecystectomy. To the best of our knowledge, there are only a few reports on cases with celiac artery dissection and none of those with acalculous gangrenous cholecystitis. Here, we report an exceptionally rare case with celiac artery dissection.

    An 85-year-old male patient was referred to our hospital for further examination of a liver tumor. Imaging examination revealed a 90-mm tumor in segment 4/8 and 30-mm tumor in segment 6 of the liver. Histopathological examination revealed that the tumor in segment 4/8 was cholangiolocellular carcinoma (CLC) and the tumor in segment 6 was hepatocellular carcinoma (HCC). This case shows that although the frequency of CLC is very low, recent studies have indicated the novel knowledge of CLC. Herein, we report a surgical case of CLC and HCC in the background of resolved hepatitis B virus infection.

    In the course of treatment for myasthenia gravis, enlargement of a cystic mass in the liver with peripheral bile duct dilation, diffuse pancreatic enlargement, and serum IgG4 level elevation was identified in a 65-year-old man. Following the diagnosis of autoimmune pancreatitis, a left hepatectomy was performed because of suspected malignancy of the cystic lesion. Analysis of the resected specimen revealed the cystic lesion to be a dilated bile duct. Intraductal papillary tumor comprising fibrovascular stalks covered by neoplastic epithelium was identified in the lesion. Infiltration of IgG4-positive plasma cells was discovered around the cystic lesion. Finally, a diagnosis of intraductal papillary neoplasm of bile duct with IgG4-related sclerosing cholangitis was made. Autoimmune diseases, including IgG4-related diseases, require careful observation because of their potential for malignancy.
