Standards of pancreaticoduodenectomy in a tertiary referral centre in Hong Kong: retrospective case series.

Abstract

OBJECTIVE: To evaluate the perioperative outcomes of pancreaticoduodenectomy in a tertiary referral centre in Hong Kong. DESIGN: Retrospective case series. SETTING: University teaching hospital, Hong Kong. PATIENTS: One hundred and forty patients who underwent pancreaticoduodenectomy from July 1989 through June 2001. MAIN OUTCOME MEASURES: Mortality and morbidity. RESULTS: Overall hospital mortality among 140 patients was 2.9% (n=4), and 30-day operative mortality was 2.1% (n=3). There was no significant difference in the hospital mortality rate between 43 elderly patients aged 70 years or older and 97 younger patients (2.3% versus 3.1%). The overall morbidity rate was 38.6% (n=54). Intra-abdominal abscess (13.6%) and pancreaticojejunal anastomotic leakage (12.9%) were the two most common complications. Presence of co-morbid illness (risk ratio, 2.823; 95% confidence interval, 1.541-4.385; P=0.01), preoperative cholangitis (risk ratio, 2.565; 95% confidence interval, 1.166-5.643; P=0.02), and intra-operative blood loss >/=1.5 L (risk ratio, 2.236; 95% confidence interval, 1.132-6.213; P=0.03) were independent risk factors for postoperative morbidity. CONCLUSIONS: Pancreaticoduodenectomy is associated with a low risk of operative death when performed in a tertiary referral setting in Hong Kong. The postoperative morbidity rate remains high, however. Further improvement by reducing intra-operative blood loss may help curtail the high postoperative morbidity.
