Background:
Patients with diffuse porto-mesenteric venous thrombosis (PMT) are often not candidates for shunt surgery.  Multi-visceral transplantation (MVT) is viewed as the only life-saving option despite normal liver and intestinal function.  While results of MVT steadily improve, a 5-year survival of the order of 50%, a mortality rate on the waiting list that may be as high as 25% and the need for life-long immuno-suppression forces a search for alternatives whenever possible. 
Goal:
To report our initial experience with a conservative, step-wise surgical approach in patients with diffuse PMT referred for MVT.
Method:
For the purpose of this report, PMT was defined as confluent thrombosis of portal, superior mesenteric, splenic and inferior mesenteric veins.  We conducted a retrospective review of all patients with PMT referred to a single surgeon for MVT.  Surgical options graded along a risk-continuum included traditional shunts followed by make-shift shunts, devascularization procedures (single-stage, modified Sugiura operation with splenectomy, gastric/esophageal devascularization and stapled esophageal transection) and finally isolated liver transplant or MVT. 
Results:
Ten patients met criteria for inclusion in this study.  There were 4 modified Sugiura procedures, 1 meso-atrial shunt using synthetic graft, 1 isolated liver transplant and 2 MVT.  Two patients remain on medical treatment with close monitoring and no evidence of re-bleeding on close follow up.
All 4 patients who underwent modified Sugiura operations, remain alive and bleed-free with normal native liver and intestinal function at 8 years, 5.5 years, 4 years and 9 months following the procedure.  The patient with the meso-atrial shunt who was evaluated and declined for MVT because of concerns for active tuberculosis, underwent a meso-atrial shunt with PTFE graft.  She died 2.5 years after surgery from massive re-bleeding, following an overseas trip to her home country with loss of follow-up and discontinuation of anticoagulation. 
One patient was successfully transplanted with an isolated liver (after a previous aborted liver transplant elsewhere) using a sizable collateral vein and an extension graft for portal venous inflow.  He is alive with normal graft function and no re-bleed over 5 years from his transplant.   One of the 2 patients who underwent MVT in this series died from sepsis after an uneventful abdominal exenteration with MVT while the remaining MVT patient is alive with excellent graft function 4 years following her MVT.
Conclusion:  An individualized step-wise approach to the patient with complete splanchnic venous thrombosis allows avoidance of MVT in some patients.  Non-transplant surgical options such as the Sugiura procedure may help combat the high mortality on the waiting list in certain regions while allowing excellent outocmes.
