RESUMEN
UNLABELLED: The majority of simultaneous kidney-pancreas (SPK) transplants are being performed with portal-enteric drainage, which does not allow easy access to the donor pancreas. By adding a temporary venting jejunostomy (TVJ) we have been able to closely monitor patients for bleeding, anastomotic leak and rejection. METHODS: Retrospective chart review of 29 patients undergoing SPK with PE drainage from December 1996 to December 2001. RESULTS: Median follow-up was 32 months. Patient, kidney and pancreas graft survival were 93%, 90% and 93%, respectively. The most common early complications were wound infections and bleeding. No patient suffered vessel thrombosis. The most common late (greater than 3 months post-transplant) complication was gastro-intestinal bleeding. Adequate tissue was obtained for biopsy in 100% of patients with suspected pancreatic rejection. The TVJ allowed one patient to undergo donor pancreas ERCP that demonstrated the site of a pancreatic duct leak. Duodenal stump leak and anastomotic bleeding were diagnosed in one patient each via the TVJ. The median time to takedown of the TVJ was 14 months. CONCLUSION: TVJ allows patients an easy method of graft surveillance, is well tolerated, and has an acceptable complication rate. The TVJ allows access to diagnose anastomotic leak, cauterize bleeding mucosa, perform ERCP and biopsy the pancreas allograft.

Partial splenic embolization (PSE) has been demonstrated to be an effective alternative to splenectomy for patients with hypersplenism. Splenectomy in these patients can be associated with an increased risk of perioperative complications, overwhelming post-splenectomy sepsis (OPSS) and mortality. Partial splenic embolization has the advantages of non- operative intervention and resolution of the complications of hypersplenism. We report the use of this technique in patients with portal hypertension and hypersplenism awaiting liver transplant and patients that have undergone othotopic liver transplantation (OLTx) with persistent hypersplenism post-transplant. Six patients--three awaiting liver transplantation and three patients with persistent hypersplenism status post-OLTx--were treated during the period of 1993-99 at the LSUHSC/Willis Knighton Regional Transplant Center in Shreveport, Louisiana. Three patients were male and three female. All six patients had concomitant thrombocytopenia and neutropenia with platelet counts below 50,000. Patients underwent selective arterial catheterization and embolization via a percutaneous approach with Cook microcoils or PVA particles. The lower pole of the spleen was selectively embolized in all patients to achieve a 30-50% reduction in flow as determined by angiography. Patients were followed with routine computed tomography (CT) scans, platelet and WBC counts for a mean of 26 months in the pre-transplant and 37 months in the post-transplant group. In both groups, all patients had persistent resolution of thrombocytopenia and neutropenia after embolization. In the post-transplant group, one patient had persistent splenomegaly and required splenectomy for pain control. No procedure-related complications occurred in any patient. In this limited review, PSE appears to be a safe and effective treatment of persistent hypersplenism in patients with portal hypertension and those who have undergone OLTx.
