Case Reports
Sigmoid colon perforation as an unusual complication of Behçet's syndrome: report of a case.
A 47-year-old man with long-standing Behçet's syndrome presented with an acute abdomen, and was found to have perforation of the sigmoid colon. Laparotomy revealed gangrenous changes in the sigmoid colon and perforation in the center of the affected segment. This is a very rare complication of Behçet's disease, and we report this case to stress the importance of performing careful abdominal examination while evaluating patients with Behçet's disease.

This report describes a giant peritoneal loose body in the pelvic cavity. A 63-year-old man who was asymptomatic underwent a routine medical examination, which revealed a tumor in the pelvic space. ⋯ Histological examination revealed that this peritoneal loose body was made up of thick layers of fibrous tissue with a few cellular components, and necrotic fat tissue in the central position. Small peritoneal loose bodies are occasionally found during laparotomy or autopsy, but such a large one is very unusual.

We report the rare case of an intraductal papillary mucinous tumor (IPMT) in a man younger than 30 years of age. The patient was admitted with upper abdominal pain and an elevated amylase level of 662 IU/l. ⋯ Nevertheless, it can only be done in the absence of additional nodules along the pancreatic duct. A pathological diagnosis of intraductal papillary adenocarcinoma of the noninvasive type was confirmed, and both stumps were free of tumor.

Case Reports
Basaloid cell carcinoma of the esophagus with a metastatic neck tumor of unknown origin: report of a case.
A 51-year-old man was admitted to our hospital with a tumor in the right anterior region of his neck. Aspiration biopsy revealed squamous cell carcinoma (SCC). Further investigations, including upper gastro-intestinal series and endoscopy, showed two flush lesions in the middle and lower thoracic esophagus. ⋯ A diagnosis of poorly differentiated SCC of unknown origin was made for the neck tumor. Postoperative recombinant chemotherapy with cisplatin and 5-fluorouracil was given for the unknown primary site, which we still have not identified. No recurrence of the esophageal cancer has been detected.

Comparative Study
Transanal laser Doppler flowmetry to assess microcirculation in the upper rectum during abdominal aortic aneurysmectomy.
Fatal ischemic colitis can develop after abdominal aortic aneurysmectomy. We investigated the effectiveness of transanal laser Doppler flowmetry (LDF) for assessing microcirculation in the rectal mucosa during aneurysm repair. ⋯ Transanal rectal LDF is useful for continuously assessing microcirculation in the rectal mucosa during abdominal aneurysmectomy, and the data obtained with this method may reflect whether a collateral pathway to the upper rectum exists.
