喉切除术后气管造口周围复发(postlaryngectomy peristomal recurrence,PSR)是指气管断端和皮肤相连接的部位肿瘤复发。复发可位于造口一侧,缓慢地向邻近气管壁直接侵犯,亦可环绕气管造口,引起气管造口逐渐狭窄。复发可在术后6周～2年发生,亦可在多年后发生。发病率为3～14％。这种特殊类型的复发,文献报道不多。本文综述国外有关文献如下。痖状及诊断早期多无自觉症状,即使有经验的医师仔细观察,也时常不能及时发现,延误诊断。气管造口周围肿胀不平、溃疡、出血是最常见的症状。呼吸、吞咽障碍则到晚期才出现。PSR可和炎症同时存在,故对于造口周围红肿、长期抗炎治疗无效的病例应考虑到这种可能。可疑时,病理检查可明确诊断。
Laryngectomy (postraryngectomy peristomal recurrence, PSR) refers to recurrence of the tumor at the site where the tracheal stump is connected to the skin. The recurrence can be located on the side of the stoma and can be directly invaded by the adjacent tracheal wall. It can also surround the tracheostomy and cause narrowing of the tracheostomy. Recurrence can occur from 6 weeks to 2 years after surgery and can occur after many years. The incidence rate is 3 to 14%. This particular type of relapse has not been reported in the literature. This article summarizes the relevant foreign literature as follows. There are no more symptoms in the early stage of the sickle and diagnosis. Even if experienced doctors carefully observe it, they often cannot find it in time and delay diagnosis. Swelling, ulcers, and bleeding around the tracheostoma are the most common symptoms. Respiratory and dysphagia do not appear until late. PSR can be present at the same time as inflammation, so this case should be considered in cases of inflammation around the stoma and ineffectiveness of long-term anti-inflammatory treatment. Suspected pathological examination can confirm the diagnosis.
