114例术后伤口脓肿分支杆菌感染的临床病理学分析

目的 探讨术后切口脓肿分支杆菌感染的临床病理学特征，评价其诊断价值。方法 １１４例手术切口感染均为污染的手术器械消毒所致，经细菌培养及菌种鉴定证实为脓肿分支杆菌。回顾性分析感染组织的病理学特征。结果 １１４例术后切口感染中累及皮肤和皮下脂肪组织９５例（８３．３％），深层肌肉组织２１例（１８．４％），腹腔脏器、腹和肠系膜３例（２．６％），局部区域淋巴结１３例（１１．４％）。病理改变主要为肉芽肿性病变

Clinicaland pathological analysis of 114 patients with postoperative wound infections by M.abscessus

Objective To evaluate the pathological findings of postoperative wound infections by M abscessus Methods Proven sources of infections in 114 patients with postoperative wound infections were contaminated instrument disinfection liquid According to the wound exudates cultivation and bacteriologic identification, the pathogen of postoperative infections was proved M abscessus Pathological features of postoperative wound infections were analyzed retrospectively Results The postoperative wound infections in 114 cases involved cutaneous and subcutaneous tissue 95(83 3%), deep muscular tissue 21(18 4%), local lymph nodes 13(11 4%) and visceral organ, peritoneum and mesentery 3(2 6%) The main pathological appearances were granulomatous lesions and nonspecific chronic pyogenic inflammations The granulomatous lesions include pyogenic tuberculosis like granuloma, atypical tuberculosis like granuloma and tuberculosis like granuloma The three types of granuloma could be seen in the same case and the percentage of three types was 75 4%,28 1%,59 6% respectively 38 cases (33 3%) were showed red mycobacterium at acid fast stain Conclusions The pathological appearances of most postoperative wound infections by M abscessus were more or less different from those of tuberculosis Awareness of the pathologic features of the postoperative wound M abscessus infections will facilitate the diagnosis so that appropriate therapy may be initiated before the disease is far advanced and prevent infection dissemination
