Resection of Bronchogenic Cysts in Symptomatic Versus Asymptomatic Patients: An Outcome Analysis

Intrathymic growing bronchogenic cyst mimicking thymoma: A case report

Intrathymic bronchogenic cysts are extremely rare lesions, and the differential diagnosis with a banal thymic cyst or a solid tumor can be problematic. Thymic carcinomas arising within thymic cysts have also been reported. We report a case of radical thymectomy for a slowly growing small thymic cyst. The pathological finding revealed a bronchogenic cyst rather than a thymic neoplasm.

Endoscopic resection in the treatment of intramural esophageal bronchogenic cysts: A retrospective analysis of 17 cases

BACKGROUND

Intramural esophageal bronchogenic cysts (EBCs) are rare congenital malformations. Differences in reports on the clinical features of intramural EBCs and some controversies about the treatment strategy for intramural EBCs exist.

OBJECTIVES

To investigate the clinical characteristics of intramural EBCs and evaluate the safety and efficacy of endoscopic resection.

METHODS

The clinical and endoscopic features, endoscopic resection treatment, postoperative adverse events, and follow-up results of 17 patients with intramural EBCs were retrospectively studied.

RESULTS

Intramural EBCs exhibited male predominance with a male/female ratio of 58.8% (10/7) and were predominantly found in the distal esophagus. Approximately 94.1% of patients presented with gastrointestinal symptoms. All lesions were protruding masses covered by intact mucosal epithelium. The morphologies of intramural EBCs were diverse under white light endoscopy. On endoscopic ultrasonography, intramural EBCs presented as homogeneous or inhomogeneous hypoechoic or anechoic lesions. Eleven lesions originated from the muscularis propria, which underwent submucosal tunnel endoscopic resection (STER), and six lesions were from the submucosa, which underwent endoscopic submucosal dissection (ESD). Approximately 88.2% of patients underwent complete endoscopic resection. No serious pneumothorax, bleeding, pleural effusion, esophagotracheal fistula, or other adverse events occurred in all patients after endoscopic resection, and no cyst recurrence, metastasis, or esophageal scar stenosis was observed during the follow-up period.

CONCLUSIONS

Intramural EBCs can be treated by digestive endoscopic surgery. STER and ESD are safe, effective, and minimally invasive resection methods.

Case report: The safety of laparoscopic surgery for the retroperitoneal bronchogenic cyst

Introduction

Bronchogenic cyst is a congenital aberration of bronchopulmonary malformation with bronchial-type, pseudostratified cylindrical epithelium. They are usually discovered in the mediastinum and intrapulmonary but are rarely encountered in retroperitoneum. We report a case of the retroperitoneal bronchogenic cyst and perform a literature review to summarize the safety of laparoscopic resection for this rare disease.

Case presentation

We report a 57-year-old woman who was admitted to our hospital with no clinical symptoms and was found by chance to have masses in the adrenal gland area during a routine physical examination. An abdominal CT examination revealed a cystic lesion was found in the left suprarenal region. Afterward, the patient underwent a laparoscopic exploration. Histopathological findings confirmed the diagnosis of a retroperitoneal bronchogenic cyst. The patient recovered uneventfully without signs of recurrence during a 1-year follow-up period.

Conclusion

Bronchogenic cyst is rare in the retroperitoneal region. It should be considered as one of the differential diagnoses of a retroperitoneal neoplasm, especially in the left retroperitoneal region. Laparoscopic surgery is technically feasible and safe for the treatment of patients with a retroperitoneal bronchogenic cyst.
