Portal biliopathy in patients with non-cirrhotic portal hypertension: does the type of surgery affect outcome?

OBJECTIVES: After portosystemic anastomoses for biliopathy, some patients continue to suffer biliary obstruction. The effects of splenectomy and devascularization of the abdominal oesophagus and upper stomach are unclear. The aim of the current study was to determine the features of portal biliopathy (PB) in patients with non-cirrhotic portal hypertension, and to investigate outcomes in these patients after surgical procedures. METHODS: A retrospective study of 56 patients who underwent surgery for PB during 1996-2010 was conducted. Data on presenting features, treatment received and outcomes were analysed. RESULTS: In total, 41 of these patients had extrahepatic portal venous obstruction and 15 had non-cirrhotic portal fibrosis. Forty patients underwent shunt surgery and 16 underwent splenectomy and devascularization. Median bilirubin levels fell from 1.8 mg/dl (range: 0.4-5.9 mg/dl) to 1.0 mg/dl (range: 0.3-5.4 mg/dl) after shunt surgery and from 1.9 mg/dl (range: 0.6-4.0 mg/dl) to 1.2 mg/dl (range: 0.6-5.2 mg/dl) after splenectomy-devascularization. On follow-up, five of 33 patients had persistent jaundice after successful shunt surgery. These patients had a history of multiple endoscopic stentings and three patients had demonstrated a dominant common bile duct stricture preoperatively. CONCLUSIONS: Portal biliopathy was reversed in 38 of 43 patients by either portosystemic shunting or splenectomy-devascularization. In five patients, direct biliary decompressive procedures were required because of shunt blockage or a non-reversible biliary stricture.

Abdominal packing for surgically uncontrollable haemorrhage.

BACKGROUND: Using abdominal packs is often a life-saving technique for uncontrollable bleeding during operations. It prevents worsening of the hypothermia, coagulopathy and acidosis which usually accompanies massive bleeding till they may be corrected and the packs removed later. However, packing may be associated with a mortality of 56 to 82% due to continued bleeding, intra-abdominal abscesses and the compartment syndrome. We follow a policy of early abdominal packing (considering it after a 6 unit intraoperative blood loss) before the situation becomes irreversible. PATIENTS AND METHODS: Between January 1997 and September 2008, abdominal packing for uncontrollable bleed was done in 49 patients (M:F 34:15, mean age 43 years). The risk factors for mortality were analyzed. The reasons for uncontrollable bleed were: liver trauma (8), liver tumours (3), following liver transplantation (4), pancreatic necrosectomy (17) and miscellaneous causes (17). RESULTS: There were 16 postoperative deaths (32.7%). On univariate analysis, hypovolaemic shock, a low urine output, raised INR, blood requirement of more than 6 units, hypothermia <34 degrees C, metabolic acidosis and sepsis were associated with an increased mortality. However, on multivariate logistic regression only hypothermia was significantly associated with mortality. CONCLUSION: A fair survival rate can be achieved by early and judicious use of abdominal packing especially before hypothermia supervenes.
