Comparison Of Pancreatic Function And Quality Of Life Between Patients With Infected Pancreatitis Necrosis Undergoing Open Necrosectomy And Minimally Invasive Drainage: A Long-Term Study

The present study aimed to determine whether a difference in pancreatic function and quality of life (QoL) is present between patients with infected pancreatitis necrosis (IPN) undergoing open necrosectomy (ON) and minimally invasive drainage (MID). The medical records of patients with IPN discharged from Jinling Hospital were retrospectively analyzed. Pancreatic function and QoL were compared between patients treated with ON and MID. Pancreatic endocrine and exocrine function were assessed using the oral glucose tolerance test and fecal elastase-1 (FE-1) test, respectively. The standard Short Form 36 health questionnaire was used to evaluate the QoL of patients. The analysis included 101 patients who underwent either ON (n=40, 39.6%) or MID (n=61, 60.4%). There were no significant differences in exocrine and endocrine pancreatic function between the two groups evaluated based on FE-1, fasting blood glucose, glycated hemoglobin and 2-h plasma glucose (P < 0.05). The scores of the QoL questionnaire were significantly higher in patients treated with MID than in patients treated with ON, including the scores of general health perception (19.39 +/- 3.07 vs. 17.37 +/- 3.63, P=0.003), vitality (18.93 +/- 2.88 vs. 17.57 +/- 3.47, P=0.035), social role functioning (8.85 +/- 1.43 vs. 8.15 +/- 1.98, P=0.042), emotional role functioning (5.33 +/- 1.07 vs. 4.82 +/- 1.25, P=0.034), mental health (24.21 +/- 3.31 vs. 22.57 +/- 3.91, P=0.026) and the total QoL score (125.12 +/- 13.16 vs. 116.50 +/- 16.94, P=0.005). In conclusion, although the initial health of the patient may have influenced the treatment provided, patients with IPN who received MID achieved a better post-treatment QoL than those treated with ON. No significant differences between the two groups were observed regarding the endocrine and exocrine functions of the pancreas.
