AbstractThe surgeon should take pains to section and study himself the operative specimen after excision for acute pancreatitis, in order to understand the true nature of the lesions, which the most attentive and competent pathological examination cannot describe as vividly as direct examination by the operator. Often he will be surprised to find that the lesions, predominant in the capsule, are less profound and less severe than he had thought at first sight. The necrosis, which is sometimes limited to the peripheral and interstitial tissue, sparing the gland itself (its prognosis is less serious and has led many surgeons to perform surgical excision). However the problems encountered postoperatively have given rise to doubts a posteriori as to whether this is legitimate. Reference is made to the decapsulation of the pancreas described by Romanian authors, and a method for future operative diagnosis of glandular necrosis is proposed.
