Endoscopic retrograde cholangiopancreatography in the evaluation of anomalous junction of the pancreaticobiliary duct and related disorders.

BACKGROUND: Anomalous junction of the pancreaticobiliary duct (AJPB) is a rare finding in endoscopic retrograde cholangiopancreatography (ERCP). We present our data on the incidence of AJPB and associated diseases. METHODS: A retrospective analysis of 2885 ERCPs performed over 15 years was done to study the incidence of AJPB and the diseases associated with this anomaly. RESULTS: Of the 2885 patients who underwent ERCP, AJPB was seen in 46 (1.6%). AJPB was taken as a common channel exceeding 15 mm in length with or without dilatation of the common channel. Anomalous junction was of type I in 50%, type II in 39.1%, and type III in 2.2% cases. Y-type anomalous junction was seen in 8.7% of cases. Choledochal cyst was found in 87% of patients. Other disorders associated with AJPB were gallstones, gallbladder polyps, gallbladder carcinoma, protein plugs. and pancreatic ductal calculi. Four patients with AJPB did not show any associated abnormality. CONCLUSION: AJPB is a rare finding, and the diagnosis is based on a common channel longer than 15 mm on ERCP. Choledochal cyst is the most common association with AJPB. We believe that the clinical spectrum of AJPB may unfold further with the widespread use of cholangiographic techniques.

Small bowel tuberculosis: enteroclysis findings.

We describe the radiologic appearances of small bowel tuberculosis as shown by enteroclysis. A total of 265 patients with proven small bowel tuberculosis seen over a period of more than one decade was evaluated. All patients had positive radiologic findings as shown on enteroclysis examination. Of the 265 patients with small bowel tuberculosis, 174 had isolated small bowel involvement with a normal ileocecal region, whereas 91 had associated noncontiguous involvement of the ileocecal region. The most common radiologic finding was the presence of strictures, noted in 62.7% of cases. Most strictures were short, concentric, and smooth in outline. These strictures were solitary or multiple and located mainly in the jejunum. Other radiologic findings were adhesions (21.8%), ulcerations (9.1%), and diffuse thickening of folds (6.4%). Complications noted were in the form of enteroliths, perforations, and fistulae. The radiographic findings of small bowel tuberculosis, although non-specific, may indicate tuberculosis in a high-risk population.

Primary small bowel tumors: a radiologic-pathologic correlation.

BACKGROUND: Primary small bowel tumors are rare and their preoperative diagnosis is unsatisfactory. The cornerstone of diagnosis remains contrast radiography. The present study was done to evaluate the radiologic findings of primary small bowel tumors as shown on enteroclysis and to correlate these observations with surgical and histopathologic findings. METHODS: Seventy two patients with primary small bowel tumors identified by enteroclysis were evaluated. All the patients were subjected to jejunal biopsy or surgery. The diagnosis was established by histopathologic examination in all cases. RESULTS: Radiologic findings were suggestive of benign tumors in 19 patients and malignant tumors in 31 patients. Nonspecific findings in the form of diffuse involvement of the small bowel were noted in 22 patients. There was 100% radiologic-surgical correlation. Leiomyomas and lymphomas were the most common benign and malignant tumors, respectively. Tumor specificities were 89.5% for benign tumors and 41.5% for malignant tumors. CONCLUSION: Distinctive morphologic patterns as shown on enteroclysis are highly suggestive of specific tumor types in the majority of cases.

Reversible portal hypertension due to tuberculosis.

Presentation of abdominal tuberculosis with portal hypertension is rare. We report a 25-year-old man with portal hypertension due to compression of the portal vein by tuberculous lymph nodes at the hepatic hilum. After antitubercular therapy, features of portal hypertension disappeared as the nodes regressed.

Endocrine cell carcinoma of gall bladder.

Primary neuroendocrine carcinoma of the gall bladder is rare. We report a 70-year-old woman with a gall bladder mass and liver metastases; fine-needle aspiration cytology from these revealed neuroendocrine carcinoma. There was no evidence of any other primary site. The patient was treated symptomatically; she died within a month of discharge from hospital.

Pneumobilia--clue to an unusual cause of diarrhea.

A 65-year lady presented with diarrhea and weight loss of six months duration. Initial evaluation suggested that malabsorption was the possible underlying mechanism for the diarrhea. Work up for the common etiologies of malabsorption was non-contributory. Presence of pneumobilia raised the suspicion of a bilio-enteric fistula, which was subsequently confirmed on barium enema and endoscopic cholangio-pancreaticography to be a cholecystocolic fistula. At surgery, a fistulous tract from the fundus of the gallbladder was found to be communicating with the hepatic flexure. Fistulectomy with cholecystectomy resulted in prompt relief of symptoms. Cholecystocolic fistula (CCF) is a rare biliary fistula with diverse presentation.

Splenic hamartoma with portal hypertension: a case report.

A case of splenic hamartoma arising from the upper pole of the spleen and presenting with upper abdominal pain, ascites and pedal edema is presented. Splenectomy was performed. The histopathology, revealed splenic hamartoma of pulposal type.
