OBJECTIVES: Pancreatic resection for cancer may produce pancreatic exocrine insufficiency (PEI), which is poorly understood. This study examined the coefficient of fat absorption (CFA), symptoms, quality of life (QoL) and the accuracy of faecal elastase-1 (FE-1) measurement to predict PEI. METHODS: Forty patients were analysed following resection for pancreatic malignancy. The primary endpoint was PEI diagnosis defined by CFA <93%; secondary endpoints were PEI diagnosis using FE-1 <200 μg/g, body mass index (BMI), and symptom and QoL analysis. Interventions were 3-day stool collection, EORTC QLQ-C30 (version 1) questionnaire and patient's diary, at 6 weeks and 3, 6 and 12 months after surgery. RESULTS: CFA <93% was present in 67% of patients at 6 weeks and in 55% at 12 months. PEI using FE-1 was present in 77 and 83% of patients, respectively. No significant changes between time-points were observed. Sensitivity, specificity, PPV, NPV and accuracy for FE-1 in detecting CFA <93% were 91, 35, 70, 71 and 70%, respectively. CFA and FE-1 levels were uncorrelated. Overall, QoL increased at 6 (p = 0.0212) and 12 (p < 0.0001) months after surgery, mainly driven by physical, role and social functioning, and by appetite. Importantly, however, BMI and symptoms were unaffected by PEI, which suggests a subclinical presentation; such patients had attributes indicating poorer QoL (notably insomnia, p = 0.0012). CONCLUSIONS: PEI was common and sustained following resection and not associated with significant symptoms. These patients had a tendency toward poorer QoL. FE-1 is a poor surrogate for diagnosing impaired fat absorption. Postoperative pancreatic enzyme replacement should be considered more routinely. and IAP.
