A Successful Treatment of Broncho-Esophageal Fistula with Esophageal Stenting Using Direct Endoscopic Visualization.

Broncho-esophageal fistula (BEF) is a severe yet relatively rare connection between the bronchus and esophagus usually caused by esophageal and pulmonary malignancies. We present a case report of a 49-year-old man diagnosed with terminal lung carcinoma who developed a BEF. The thoracic computed tomography scan detected a mass in the left bronchi that partially covers and disrupts the bronchial contour in certain regions and extends to the esophageal wall. After thoroughly evaluating alternative treatment approaches, we opt for the stenting procedure due to the advanced stage of the tumor and the significantly diminished quality of life. The treatment involves the use of a partially covered metal stent that is known to exhibit lower potential to migrate. The treatment is highly successful, resulting in a significant enhancement of the patient's quality of life, a lengthening in his survival, and the ability to pursue additional palliative treatment options. In contrast to the typical prosthesis implantation, our procedure uses a direct endoscopic visualization for the proximal deployment of a partially covered stent, offering a cost-effective and radiation-free alternative that can be particularly beneficial for BEF patients in facilities without radiology services.

MSCT study for adult esophageal diverticulum with secondary broncho-esophageal fistula.

BACKGROUND: Broncho-esophageal fistula (BEF) secondary to esophageal diverticulum is a rare clinical condition, which is often misdiagnosed for a long time. The aim of our study is to summarize and clarify the advantages of MSCT in diagnosing BEF secondary to esophageal diverticulum. METHODS: We retrospectively analyzed patients clinically diagnosed with BEF from January 2005 to January 2022 at Jilin University First Hospital. Only those patients with BEF secondary to esophageal diverticulum and complete clinical data met our enrolled standard. All patients' clinicopathologic characteristics and MSCT features were systemically evaluated. RESULTS: 17 patients were eligible for our cohort study, including male 10 and female 7. The patient's mean age was 42.3 ± 12.5. The chronic cough occurred in all seventeen patients and bucking following oral fluid intake was documented in nine patients. MSCT distinctly suggested the fistulous tract between the bronchi and the esophagus in all patients. The mean diameter of the orifices in the wall of the esophagus was 4.40 ± 1.81 mm. The orifice in the midthoracic esophagus side was 15 cases and 2 cases at the lower thoracic esophagus. The involved bronchus included 13 cases at the right lower lobe bronchus, 1 at the right middle lobe bronchus and 3 at the left lower lobe bronchus. The contrast agent was observed in the pulmonary parenchyma in 10 of 13 patients who underwent esophagogram. No definite fistula was observed in 3 of 11 who underwent gastroscopy, while the intra-operative findings supported the existence of fistula. CONCLUSIONS: BEF secondary to esophageal diverticulum tends to occur between the midthoracic esophagus and the right lower lobe bronchus. Compared with esophagography and gastroscopy, MSCT shows more comprehensive information about the fistulous shape, size, course and lung involvement, which are helpful for establishing diagnosis and guiding subsequent treatment.

Broncho-esophageal fistula: When surgery and endoscopy fail, consider physiological lung exclusion.

We discuss the case of an esophageal cancer patient treated by chemo and radiotherapy complicated by an esophageal stenosis and an iatrogenic broncho-esophageal fistula. This latter was managed with multiple palliative stenting procedures and colonic surgical bypass. Despite a long disease free survival but decreased quality of life and frailty, we came to the proposal of an extremely unusual form of treatment - physiological lung exclusion, with clinical benefit and so far without any drawbacks related to the procedure.

A rare case of pulmonary mucormycosis and broncho-esophageal fistula in a patient with poorly controlled diabetes.

Key Clinical Message: In patients with poorly controlled diabetes, early recognition of rare fungal infections like pulmonary mucormycosis, especially when presenting with unusual complications such as broncho-esophageal fistula, is critical. Prompt intervention with antifungal therapy and consideration for surgical debridement significantly impact outcomes. Multidisciplinary management is paramount for such complex cases. Abstract: Mucormycosis is a rare fungal infection caused by the Mucorales. This infection is mostly observed among those with poorly controlled diabetes or immunodeficiency. The most common presentation of the infection among those with poorly controlled diabetes is rhino-orbit-cerebral involvement. In this case report, we provide the history and outcome of a rare case of pulmonary mucormycosis in a patient with poorly controlled diabetes who was simultaneously diagnosed with broncho-esophageal fistula. Our patient was a 32-year-old male with a history of poorly controlled diabetes. Over the months, he had complained of productive coughs and dyspnea, which had lately been joined by dysphagia. He also claimed to have lost considerable weight (10 kg) during the previous 3 months. Barium swallow showed an abnormal flow of contrast between the bronchus and esophagus, suggesting a broncho-esophageal fistula. Computed tomography of the thorax revealed a broncho-esophageal fistula between the left main bronchus (LMB) and esophagus. He had a bronchoscopy the next day, which revealed necrosis and a broncho-esophageal fistula in the LMB. A bronchial biopsy showed typical hyphae with necrotic tissue, indicating mucormycosis. The patient's antimycotic medication (liposomal amphotericin) was started and a prompt surgery consult was ordered. The patient, however, passed away from massive hemoptysis. We described a rare case of pulmonary mucormycosis with broncho-esophageal fistula in a patient with poorly controlled diabetes. The rarity of this combination highlights the associated diagnostic and treatment hurdles. Early detection, antifungal medication, as soon as possible surgical debridement of involved tissues, and a multidisciplinary approach could improve patient outcomes.
