Cholecystojejunostomy varices demonstrated by enteroclysis

Unusual bleeding from hepaticojejunostomy controlled by side-to-side splenorenal shunt: A case report

RATIONALE

Ectopic variceal bleeding due to hepaticojejunostomy (HJ) is unusual and difficult to manage. Reports on the use of side-to-side splenorenal shunt for severe bleeding from varices at HJ anastomosis are lacking.

PATIENT CONCERNS

A 43-year-old man was admitted to our hospital with repeated episodes of hematemesis. He has a history of right hemihepatectomy with HJ reconstruction to the left hepatic duct for hilar cholangiocarcinoma. Two years after surgery, he presented with repeated episodes of hematemesis and underwent blood transfusion.

DIAGNOSES

Imaging tests and endoscopic investigation failed to identify the bleeding source. When conservative management failed to control his bleeding, he underwent emergency laparotomy, which revealed hemorrhage from ectopic varices at the HJ anastomosis.

INTERVENTIONS

To arrest the bleeding, a side-to-side venovenal anastomosis was created between the splenic and left renal veins to form a shunt for decompression of the varices at the HJ anastomosis.

OUTCOMES

After the surgery, the patient's symptoms ceased, and a no bleeding in the digestive tract was noted at 2-year follow-up.

LESSONS

The present patient is the first reported case of unusual bleeding from HJ controlled by a side-to-side splenorenal shunt. We believe this approach is a useful and effective surgical treatment for severe bleeding from varices at the HJ anastomosis.

Jejunal varix bleeding with extrahepatic portal vein obstruction after pylorus-preserving pancreatoduodenectomy: report of two cases

We present 2 patients showing afferent jejunal varix bleeding around hepaticojejunostomy caused by extrahepatic portal vein obstruction after pylorus-preserving pancreatoduodenectomy (PPPD). The case 1 was a 58-year-old woman who had recurrent anemia and hematochezia 3 years after undergoing PPPD. On the portography, the main portal vein was obliterated and collaterals around hepaticojejunostomy were developed. After percutaneous transhepatic balloon dilatation and stent placement through the obliterated portal vein, jejunal varices had disappeared and thereafter no bleeding occurred for 32 months. The case 2 was a 71-year-old man who had frequent melena 7 years after PPPD. Portal stent insertion was first tried, but failed due to severe stenosis of the main portal vein. Therefore, meso-caval shunt operation was attempted in order to reduce the variceal flow. Although an episode of a small amount of melena occurred one month after the shunt operation, there was no occurrence of bleeding for the next 8 months. For the treatment of jejunal varices, a less invasive approach, such as the angiographic intervention of stent insertion, balloon dilatation, or embolization is recommended first. Surgical operations, such as a shunt or resection of the jejunal rim, could be considered when noninvasive approaches have failed.

Successful embolization therapy for bleeding from jejunal varices after choledochojejunostomy: report of a case

We report a case of successful embolization of jejunal varices that were the cause of massive gastrointestinal bleeding from a choledochojejunostomy site, resulting from obstruction of the extrahepatic portal vein. A 42-year-old man who had undergone choledochojejunostomy for intrahepatic and choledochal stones was readmitted after he started passing massive dark bloody stools. Gastrointestinal endoscopic examination and angiography could not identify the source of bleeding. Percutaneous transhepatic portography showed obstruction of the right branches of the portal vein. The formation of jejunal varices at the site of choledochojejunostomy was revealed by portography and by cholangioscopy, suggesting the varices as the cause of massive bleeding. Bleeding could not be controlled long-term by cholangioscopic sclerosing therapy. We finally stopped the bleeding by embolizing a jejunal vein to the afferent loop.

Successful endoscopic sclerotherapy for cholecystojejunostomy variceal bleeding in a patient with pancreatic head cancer

Variceal bleeding outside the esophagus and stomach is rare but important because of its difficult diagnosis and treatment. Bleeding from cholecystojejunostomy varices has been reported to be a late complication of palliative biliary surgery for chronic pancreatitis. Such ectopic variceal bleeding has never been reported after palliative surgery for pancreatic cancer, probably because of the limited lifespan of these patients. Herein, we report our successful experience using endoscopic cyanoacrylate sclerotherapy to treat bleeding from cholecystojejunostomy varices in a 57-year-old man with pancreatic head cancer. To our knowledge, this is the first case report in the literature of this rare complication.

Trans-anastomotic porto-portal varices in patients with gastrointestinal haemorrhage

AIM

Porto-portal varices are commonly seen in patients with segmental extra-hepatic portal hypertension and develop to provide a collateral circulation around an area of portal venous obstruction. It is not well recognized that such communications may also develop across surgical anastomoses and be the source of gastrointestinal haemorrhage. The possible mode of development of such communications has not been previously discussed.

MATERIALS AND METHODS

Over a 3-year period between 1995 and 1998, porto-portal varices were demonstrated across surgical anastomoses in four patients who were referred for the investigation of acute (two), acute-on-chronic (one) and chronic gastrointestinal bleeding (one). Their medical notes and the findings at angiography were reviewed.

RESULTS

Three patients had segmental portal hypertension due to extra-hepatic portal vein (one) or superior mesenteric vein (two) stenosis/occlusion. One patient had mild portal hypertension due to hepatic fibrosis secondary to congenital biliary atresia. At angiography all patients were shown to have varices crossing previous surgical anastomoses. These varices were presumed to be the cause of bleeding in three of the four patients; the site of bleeding in the fourth individual was not determined.

CONCLUSIONS

Trans-anastomotic porto-portal varices are rare. They develop in the presence of extra-hepatic portal hypertension and presumably arise within peri-anastomotic inflammatory tissue. Such varices may be difficult to manage and their prognosis is poor when bleeding occurs.
