Leiomyoma is the most common benign esophageal tumor that originates in the muscular layer, with the most common site located in the distal third of the esophagus. Its growth causes symptoms due to partial obstruction of the esophageal lumen, leading to the diagnosis and subsequent treatment. Today, due to modern minimally invasive surgical techniques, complete removal of these tumors can be accomplished with minimal morbidity and excellent results.
We report the case of a 49-year-old female with a history of dysphagia, epigastric pain, and halitosis. She was diagnosed with a benign tumor originating from the muscular layer of the distal esophagus. Multiple biopsies had previously been taken, without histological confirmation. The patient underwent surgery where complete tumor enucleation was done laparoscopically.
Preoperative diagnosis of these tumors should be based on clinical history and studies such as esophagoscopy and endoscopic ultrasound. Laparoscopic enucleation is the treatment of choice for leiomyomas of the esophagogastric junction. Biopsy specimens should be avoided because histology is not always possible. Furthermore, they are related to rupture of the esophageal mucosa during surgical treatment. After enucleation in selected patients, anti-reflux procedure should be carried out in order to protect the area of surgical resection and prevent complications from weakening the lower esophageal sphincter, as well as to resolve reflux symptoms.
平滑肌瘤是最常见的起源于肌层的良性食管肿瘤,最常见的部位位于食管远端三分之一处。其生长因食管腔部分梗阻而导致症状,从而得以诊断并进行后续治疗。如今,由于现代微创手术技术,这些肿瘤能够以最低的发病率实现完整切除,且效果极佳。
我们报告一例49岁女性患者,有吞咽困难、上腹部疼痛和口臭病史。她被诊断为起源于食管远端肌层的良性肿瘤。此前已进行多次活检,但未得到组织学确诊。该患者接受了手术,通过腹腔镜完成了肿瘤完整摘除。
这些肿瘤的术前诊断应基于临床病史以及食管镜检查和内镜超声等检查。腹腔镜摘除术是食管胃交界部平滑肌瘤的首选治疗方法。应避免获取活检标本,因为不一定能进行组织学检查。此外,活检标本与手术治疗期间食管黏膜破裂有关。在选定患者进行摘除术后,应实施抗反流手术,以保护手术切除区域,防止因食管下括约肌功能减弱而引发并发症,并缓解反流症状。
