The aim of this study was to determine the rate of negative appendectomy in a company hospital in Nigeria.
Appendicitis is one of the most common abdominal conditions requiring surgical intervention. Appendectomy, like most surgical procedures, has its complications and therefore should only be undertaken when indicated. Case series have reported the incidence of negative appendectomy in Western nations. The purpose of this retrospective study is to evaluate the incidence of negative appendectomy in a Nigerian hospital, where all the operations were carried out by consultant surgeons.
All case files of patients who received an appendectomy at Chevron Hospital in Warri, Nigeria between January, 1999 and December, 2003 were reviewed. Demographic data, symptoms and signs on presentation, intra-operative findings and histological reports on the excised vermiform appendixes were extracted from the case files and analyzed.
The incidence of negative appendectomy in this study was 16.1%; all nine patients that had negative appendectomy were female.
The incidence of negative appendectomy observed at Chevron Hospital in Warri, Nigeria is lower than that reported by most studies; one factor may be that all the patients in the present study were evaluated and operated on by consultant surgeons.
本研究旨在确定尼日利亚一家公司医院的阴性阑尾切除术发生率。
阑尾炎是最常见的需要手术干预的腹部疾病之一。阑尾切除术和大多数外科手术一样，有其并发症，因此仅应在有指征时进行。病例系列报道了西方国家阴性阑尾切除术的发生率。这项回顾性研究的目的是评估尼日利亚一家医院的阴性阑尾切除术发生率，该医院所有手术均由顾问外科医生进行。
回顾了1999年1月至2003年12月期间在尼日利亚瓦里雪佛龙医院接受阑尾切除术的所有患者的病例档案。从病例档案中提取人口统计学数据、就诊时的症状和体征、术中发现以及切除的阑尾的组织学报告并进行分析。
本研究中阴性阑尾切除术的发生率为16.1%；所有9例阴性阑尾切除术患者均为女性。
在尼日利亚瓦里雪佛龙医院观察到的阴性阑尾切除术发生率低于大多数研究报告的发生率；一个因素可能是本研究中的所有患者均由顾问外科医生进行评估和手术。
