Long-Term Functional Outcome After Pancreatoduodenectomy for Periampullary Carcinoma With Morphological Correlation.



OBJECTIVE\nThe aim of the study was to evaluate the long-term functional outcome (exocrine and endocrine) and morphological changes in remnant pancreas after pancreatoduodenectomy and its clinical impact.\n\n\nMETHODS\nPeriampullary carcinoma patients with minimum follow-up of 2 years and without recurrence were included (N = 102). Exocrine insufficiency includes clinical steatorrhea and fecal elastase-1 (FE-1) levels; endocrine insufficiency, glucose levels and glycated hemoglobin; and morphological changes, main pancreatic duct (MPD) diameter and thickness of remnant pancreas.\n\n\nRESULTS\nThe mean (SD) follow-up period was 59 (26) months. Of the 102 patients, 81 (80%) had severely deficient FE-1 (0-100 μg/g). The preoperative MPD was significantly more and thickness of remnant pancreas was significantly less in patients with severely deficient FE-1. Overall, 15.6% (16/102) developed steatorrhea and improved on enzyme replacement therapy. The presence of MPD stricture (P = 0.008) and weight loss (P = 0.001) were significantly associated with steatorrhea. New-onset diabetes was seen in 17% (15/90) patients, of whom 3 of 5 developed it after 4 years (range, 4-7 years). The blood glucose was controlled on oral hypoglycemics in 2 (10/15) of 3 patients.\n\n\nCONCLUSIONS\nThe assessment by FE-1 indicates loss of exocrine function in more than 90%, whereas only 1 of 6 developed steatorrhea and new-onset diabetes. Morphological changes especially MPD stricture affect the functional status of remnant pancreas.
