Pseudoaneurysm of gastroduodenal artery associated with mitral valve prolapse presenting as haemobilia.

Pseudoaneurysms of the hepatic or gastroduodenal arteries may cause Haemobilia. Mitral valve prolapse associated with mycotic pseudoaneurysm of cerebral and extracerebral arteries have been reported. We report a case of gastroduodenal artery pseudoaneurysm presenting as haemobilia. The patient was successfully treated with indigenously fabricated steel coil embolization followed by surgery.

Percutaneous transhepatic biliary drainage in the management of obstructive jaundice.

BACKGROUND: Percutaneous transhepatic biliary drainage (PTBD) has been employed for decompression of the obstructed biliary tract to palliate jaundice and pruritus and for the management of cholangitis. We present our data to review the indications, therapeutic results and associated mortality and complications of this procedure. We have also studied the effect of size of drainage catheters on the improvement in liver functions and procedure related complications. METHODS: PTBD was attempted in 41 patients (18 men, age 56 +/- 12 years; 23 women, age 55 +/- 11 years) with obstructive jaundice (37 malignant, 4 benign). RESULTS: PTBD was successful in 39 (95%) patients. Mean serum bilirubin and alkaline phosphatase concentration declined significantly (p < 0.000001 for both) after 1 week, however thereafter decline was slow. Complete relief of pruritus and cholangitis was noted in most patients. Major complications such as cholangitis, bile leak into the peritoneum, malfunction of drainage catheter, intraperitoneal haemorrhage and renal failure, occurred in 11 (28%) patients, 2 (5%) of whom died. Large catheters (> 10 Fr) were superior to small size catheters (< 10 Fr) in relief of jaundice and had lower catheter related cholangitis. CONCLUSIONS: We conclude that PTBD is useful for palliation of malignant obstructive jaundice with intractable symptoms and cholangitis. Catheters larger than 10 Fr should be used.

Intraoperative ultrasonography for insulinoma: a preliminary experience.

BACKGROUND: A majority of insulinomas are benign and intrapancreatic. Because surgery is curative in 90% of cases, and almost 60% are not detected by preoperative imaging studies, precise intraoperative localization is essential. Recently, the use of high-resolution real-time ultrasonography has facilitated intraoperative detection. METHODS: Intraoperative ultrasonography using a high-frequency probe was performed in four patients with biochemically proven insulinomas. RESULTS: Ultrasonography helped to localize the insulinomas, and also helped in surgical decision-making by accurately documenting the relationship of the tumor to vital structures. CONCLUSION: Besides its ability to find islet cell tumors, intraoperative ultrasonography also affects surgical decision-making.

Therapeutic gastrointestinal endoscopy.

The safety, efficacy and utility of various therapeutic gastrointestinal (GI) endoscopic procedures performed on children (January 1992 to July 1995) at a tertiary referral centre in India were studied. A total of 1,030 sessions (upper GI 972 and lower GI 58) of therapeutic GI endoscopy were performed in 162 children (mean age 7.4 +/- 4 years; upper GI 115, lower GI 47). Various upper GI endoscopic procedures done were injection sclerotherapy (EIS), endoscopic variceal ligation (EVL), bougie dilatation of oesophageal strictures, balloon dilatations of oesophageal stricture/pyloric obstruction and retrieval of foreign bodies in 75%, 6%, 9%, 4% and 12% of children respectively. Therapy for bleeding from oesophageal varices constituted the major group (75%). Repeated EIS (sessions total--876, mean 8, range 5-15) performed on 86 children resulted in control of bleeding in all and eradication of oesophageal varices in 85% of cases. Minor complications (oesophageal ulcers and oesophageal strictures) due to EIS were observed in 9% of children. EVL (10 sessions in 7 children) was effective in controlling bleeding and substantial decrease of varices in all without any complication. Oesophageal dilation either by bougie (61 sessions in 10 children) or balloon (6 sessions in 3 children) were performed for benign strictures. Balloon dilatation of pyloric obstruction was successfully done in 2 children. Foreign bodies (retained or sharp) were retrieved from upper GI tract in 14 children. No complications were observed with stricture dilatation/foreign body retrieval. Therapeutic lower GI endoscopies were performed in 47 children (colonoscopic polypectomy in 92%, anal dilatation and piles banding in 4% each). One child with juvenile polyposis coli developed sigmoid colon performation following colonoscopic polypectomy which required surgical correction. We conclude that upper and lower GI endoscopic therapeutic procedures in children are highly effective and safe. The risk of major complication is very small in experienced hands and occasional minor complications, can be managed conservatively.

Biliary ascariasis associated with periampullary carcinoma.

A 65 year old man presented with obstructive jaundice, biliary colics and recurrent cholangitis. Sonography revealed dilated intrahepatic biliary radicles and common bile duct. Bile duct also showed linear parallel intraluminal structures suggesting biliary ascariasis. The lower end of common bile duct and pancreatic region showed a mass which proved to be a coexistent periampullary carcinoma.

Extra-anatomic stenting of the biliary system.

Tumor necrosis interfered with conventional methods of stenting in a patient with hilar cholangiocarcinoma. Therefore, a hepaticoduodenal fistula was percutaneously catheterized and dilated, and a large caliber endoprosthesis inserted to drain the right hepatic ductal system.

Primary sclerosing cholangitis with chronic pancreatitis.

We report a patient with primary sclerosing cholangitis and associated pancreatitis. She had exocrine and endocrine pancreatic insufficiency.
