    We reviewed 428 subjects with colorectal serrated lesions resected endoscopically or surgically at our institution. Colorectal serrated lesions were pathologically divided into 3 groups: hyperplastic polyp (HP), sessile serrated adenoma/polyp (SSA/P), and traditional serrated adenoma (TSA). SSA/P was detected frequently in the right colon and SSA/P was mainly flat-elevated. Cancers occurring in SSA/P were found more frequently than HP or TSA. The incidence of cancer in SSA/P was equivalent to that of cancer in traditional adenoma. Further studies are warranted to clarify clinicopathological features of serrated lesions of the colorectum.

    We report abdominal bleeding caused by arteriovenous malformations (AVM) of the posterior gastric artery. A 38-year-old man visited our hospital complaining of epigastralgia. Enhanced abdominal CT revealed a high density spot in a huge low density mass. Angiographic study showed AVM of the posterior gastric artery. Transcatheter arterial embolization was performed and we successfully treated the AVM which was accompanied by abdominal bleeding.

    A 49-year-old man was admitted to our hospital because of recurrent gastrointestinal bleeding of unknown origin, after repeated negative endoscopic and radiographic evaluation, including colonoscopy, esophago-gastro-duodenoscopy, CT and angiography. His condition had not been diagnosed for the past 18 years. 18F-fluorodeoxyglucose (FDG) on positron emission tomography (PET/CT) showed mild FDG uptake by a tumor of the small bowel (SUVmax 2.83), and capsule endoscopy (CE) and double balloon endoscopy (DBE) revealed a well-defined smooth submucosal tumor in the jejunum. The patient underwent a laparotomy and small bowel resection. The pathologic diagnosis was a small intestinal leiomyoma. Our report suggests the significance of combination of CE, DBE and PET/CT in the diagnosis of small bowel leiomyoma.

    A 59-year-old woman had been admitted to our hospital every two months for over a past year because of severe right abdominal pain. Colonoscopy revealed dark blue mucosa extending from the cecum to the transverse colon, and abdominal computed tomography showed wall thickening and linear calcification along the wall from the cecum to the transverse colon. Based on these findings, the patient was given a diagnosis of idiopathic mesenteric phlebosclerosis. Subsequently, we found that she had been a long-term user of a Chinese herbal product containing Gardeniae fructus for allergic rhinitis. After discontinuing the product, the patient has been free of abdominal pain for a year.

    A 69-year-old man was admitted to our hospital with epigastric discomfort. Upper gastrointestinal endoscopy showed a submucosal tumor near the papilla of Vater. Abdominal CT and MRI showed a small, well-enhanced tumor. Endoscopic tumor biopsy was performed before the operation, but pathologic findings showed normal duodenal musosa. Nevertheless, since malignancy could not be ruled out, we resected the tumor with the sphincter of the papilla of Vater, followed by plasty of the orifice for the common bile duct and main pancreatic duct. We identified 3 parts with tumor cells; epithelioid cells, spindle cells, and ganglion-like cells. The tumor was diagnosed as gangliocytic paraganglioma of the duodenum. Treatment by resecting the tumor with the sphincter of the papilla of Vater, followed by the plasty of the orifice for the common bile duct and main pancreatic duct, was selected considering the patient's safety and to achieve radical cure.

    We present a case of a 61-year-old woman who underwent endoscopic mucosal resection (EMR) for early-stage colorectal cancer. However, because the condition of the horizontal margin of the resected tumor was unknown, she further underwent local transanal excision. Lower gastrointestinal endoscopy performed 1 year later showed protruding lesions both on the scar tissue and in the vicinity. Biopsy revealed malignant melanoma. She then underwent laparoscopic abdominoperineal resection and colostomy. This was an extremely rare case of adenocarcinoma complicated by malignant melanoma after resection.

    A 77-year-old woman was referred to our hospital because of right-back pain. Dynamic computed tomography (CT) studies showed a huge tumor in the right lobe of the liver. After admission, transcatheter arterial embolization (TAE) was immediately performed because of the risk of rupture. The tumor, however, was hypovascular and we judged that the procedure had no effect on preventing rupture. Therefore, based on a diagnosis of cystadenocarcinoma or cholangiocarcinoma, we conducted right trisegmentectomy and caudate lobectomy in July 2010. The definitive pathological diagnosis was intrahepatic cholangiocarcinosarcoma. The postoperative course was uneventful, and the patient was discharged on postoperative day (POD) 17. Afterwards, despite chemotherapy treatment, a local recurrence on the right diaphragm was detected 2 months postoperatively, and she died 4 months postoperatively. Intrahepatic cholangiocarcinosarcoma is very rare. We report this case with a review of some relevant literature.

    We report here two cases of neuroendocrine carcinoma which occurred in the biliary system. The prognosis of neuroendocrine carcinoma in the biliary system is generally poor. However, based on the preoperative pathological diagnosis of neuroendocrine carcinoma, multidisciplinary treatment consisting of preoperative chemotherapy, chemoradiation therapy, curative resection and adjuvant chemotherapy seemed to be very effective and long-term survival was obtained in our two cases. Therefore it is essential to diagnose preoperatively to improve prognosis.
