Acute appendicitis is one of the most common etiologies of a surgical abdomen. The lifetime risk is estimated to be 7%. Over 300 000 appendectomies occur annually in the USA. The pathophysiology of appendicitis in most patients is believed to be caused by outflow obstruction of the appendiceal lumen leading to increased intraluminal pressure, venous congestion and mucosal ischemia. This can occur due to a variety of internal obstructive causes such as a fecalith, lymphoid hyperplasia, parasites or a tumor. To date, no case reports describing appendicitis secondary to external compression of the appendix leading to outflow obstruction been documented in the literature. This case report describes a 61-year-old female who had a thick, adhesive band compressing the base of her appendix, which created external outflow obstruction leading to the development of appendicitis.
急性阑尾炎是外科急腹症最常见的病因之一。终生患病风险估计为7%。美国每年进行超过30万例阑尾切除术。大多数患者阑尾炎的病理生理学被认为是由阑尾腔流出道梗阻导致腔内压力升高、静脉淤血和黏膜缺血引起的。这可能由于多种内部梗阻原因而发生，如粪石、淋巴组织增生、寄生虫或肿瘤。迄今为止，文献中尚无描述因阑尾外部受压导致流出道梗阻继发阑尾炎的病例报告。本病例报告描述了一名61岁女性，其阑尾根部被一条增厚的粘连带压迫，造成外部流出道梗阻，进而引发阑尾炎。
