A new twist to situs inversus To the Editor:

etiopathogenesis of GAVE and arterial spiders appear to be different. s To the best of our knowledge, no specific patterns have been described in the colonic mucosa of cirrhotic patients. In a recent report of a large series of colonoscopies in cirrhotics, a high prevalence of polyps and varices was reported. 9 Kozarek et al. 10 recently described the existence of a portal colopathy which consisted of ulcerations and telangiectasias. Our case suggests that the colonic mucosa of cirrhotic patients can exhibit microvascular abnormality as arterial spiders. Further studies should be focused on the frequence of this lesion and its eventual association with other lesions such as skin spiders and/or GAVE.

Transposition of thoracic and abdominal viscera rarely occurs. Situs inversus has been the subject of many reviews and case reports because of its rarity. Some of the gastrointestinal problems described include duodenal ulcer perforation, cholecystitis requiring cholecystectomy, liver transplantation for biliary atresia, and choledocholithiasis necessitating ERCP and papillotomy.1-4 We add a new "twist" to the situs inversus literature by reporting the placement of a bile duct endoprosthesis for relief of an obstructing bile duct stricture. A 65-year-old man with known chronic pancreatitis underwent ERCP for abdominal pain and bile duct dilation. Unlike previous reports of endoscopy in patients with situs inversus,4 we successfully intubated the duodenum with the patient lying on his left side. Cannulation of the ampulla was performed in the standard fashion. The cholangiogram was, as one would expect, in the reverse position. There was a distal common duct narrowing from chronic pancreatitis. Following a limited sphincterotomy, a 9-cm, 10 F Amster-

Editor for Abstracts, James Barthel, MD
To the Editor: Pedunculated tumors of the esophagus are rare, and malignant tumors even rarer. We present an unusual case of pedunculated carcinoma of the esophagus. A 36-year-old man presented with weight loss, fever, and dysphagia. He had a history of heavy alcohol and tobacco use. Fiberoptic esophagoscopy showed a pedunculated tumor of the middle part of the esophagus obstructing the lumen; three biopsies were taken and showed only necrotic tissue and intense inflammation. The patient noticed a marked and sudden improvement of his dysphagia 13 days after the initial endoscopy. A second endoscopy showed the disappearance of the bulk of the tumor, with a remaining small nodule and esophageal infiltration. Biopsies of the lesion were consistent with well-differentiated epidermoid carcinoma. The disappearance of the tumor mass was radiologically confirmed by barium x-ray study. The patient underwent a thoraco-abdominal esophagectomy with an esophagogastric anastomosis and pyloroplasty. One year later he died from diffuse metastatic disease of the lungs, liver, and skin. Three points should be emphasized: (1) Pedunculated tumors of the esophagus represent 0.5 to 1% of esophageal tumors. They have a polypoid appearance and are almost always benign.! (2) Benign or malignant, these tumors are usually of mesenchymal origin, 2 but a particular form of a carcinoma, that may be pedunculated, contains fusiform cells giving a "pseudo-sarcoma" appearance. 3 (3) Spontaneous loss of a polypoid tumor is very rare, but dramatic complications were reported with asphyxiation following regurgitation,4.5 Thus, endoscopic removal is useful to confirm benign histology and to prevent mechanical complications.

Small bowel enteroscopy and intraoperative enteroscopy for obscure gastrointestinal bleeding LEWIS BS, WENGER JS, WAYE JD Am J GastroenteroI1991;86:171-4
This study retrospectively evaluated 23 patients with obscure gastrointestinal bleeding who underwent small bowel enteroscopy (SBE) and subsequent intraoperative enteroscopy (IOE). All patients had gastrointestinal blood loss averaging 2 years in duration, an average transfusion requirement of 27 units and negative workup including colonoscopy, upper endoscopy, gastrointestinal series, and barium enema. SBE was performed transnasally with the Olympus SIFSW small bowel enteroscope (Gastrointest Endosc 1987;33:435-8) and IOE was performed with an adult pediatric colonoscope during exploratory laparotomy. The average time span between enteroscopy and intraoperative endoscopy was 96.5 days (range, 2 days to 19 months). 591
