Does anyone know anything about Portal Hypertension and J-Pouches, if J-Pouch surgery or how affects the portal vein. Often anal varices can be misdiagnosed or misinterpreted as hemrroids. Now, thinking about all of the reconstruction (or deconstruction) of the lower abdomine with colectomies and anal-ileal pullthroughs (J-Pouches) and looking at a diagram of the abdomin and the Portal vein, I wonder just how these surgeries wouldn't cause issues of Hypertension of the Portal Vein, etc.
