Results of a Modified Sugiura′s Devascularisation in theManagement of “Unshuntable” Portal Hypertension

Abstract

The results of a modified Sugiura devascularisation procedure were assessed in 14 patients with thrombosis of the portal and splenic vein requiring surgery for variceal hemorrhage, with no vein suitable for orthodox shunt surgery. The venous anatomy was determined by ultrasonography with Doppler studies and portovenography. Liver biochemistry as well as liver architecture on histopathology was normal in all. The surgery was elective in 9 cases for documented bleed from diffuse fundal gastric varices (FGV) and emergency in 5 cases, 3 having bleeding FGV and 2 for failure of emergency esophageal variceal sclerotherapy. All were subjected to a transabdominal extensive devascularisation of the upper two third of the stomach and lower 7–10cm of the esophagus. Stapled esophageal transection (n=11) or esophageal variceal under-running (n=1) was performed in all with esophageal varices. FGV were underrun. Follow up endoscopies were done six monthly. There were 9 males and 5 females with a mean age of 17.2 years (SD 12.8). There was no operative mortality. Acute variceal bleeding was controlled in all patients. Over a mean follow up of 38 months, all but one remain free of recurrent bleeding. We conclude that a modified Sugiura devascularisation procedure is effective in the immediate and medium term control of variceal bleeding in patients with “unshuntable” portal hypertension.
