Purpose: The objective of this study was to present our experience with metallic stents (Wallstent) for palliation of dysphagia due to malignant esophageal obstruction and esophagotracheal fistula.

Patients And Methods: From August 1994 to July 1996 20 uncovered and 6 covered stents were inserted in 16 consecutive patients with dysphagia grade 3 (n = 4) or grade 4 (n = 12) caused by incurable malignant obstructions. The obstruction was in the proximal (n = 4), in the middle (n = 3) and the distal (n = 9) third of the esophagus. Five patients presented with esophagotracheal fistula. The stent insertion was performed under fluoroscopic control.

Results: Exact positioning of the stent with reduction of the dysphagia was obtained in all patients. There were no complications related with the procedure. Esophagotracheal fistula was solved in those patients treated with covered stents. Six patients had recurrent dysphagia due to tumor ingrowth or overgrowth. In these patients an additional overlapping stent was placed. In latest evaluation 2 patients presented dysphagia grade I, 5 grade III, and 4 grade IV.

Conclusion: Implantation of stents proved to be an effective and safe method of palliating dysphagia and occluding esofagotracheal fistula. Placement of stents was feasible without major procedure-related complications.

Background: Some surgeons routinely divide the inferior pulmonary ligament (IPL) during upper lobectomy. Nevertheless, the evidence remains inconclusive regarding whether dividing the IPL improves the postoperative pulmonary. This systematic review and meta-analysis aimed to assess the effects of inferior pulmonary ligament division (IPLD) during upper lobectomy.

Objective: The objective of this study was to evaluate the clinical efficacy and safety of neoadjuvant immunochemotherapy in the treatment of locally advanced, resectable esophageal cancer.

Methods: Literature published before November 2023 on the clinical efficacy and safety of neoadjuvant immunotherapy in resectable esophageal squamous cell carcinoma was searched in CNKI, VIP, Wanfang, Chinese Biomedical Literature, PubMed, Embase, Cochrane, and the Web of Science. A meta-analysis was conducted using Stata 17.

A young man in his 30s presented to us with multiple episodes of syncope and exertional dyspnoea for the last 2 weeks. He was diagnosed with squamous cell carcinoma of the lower one-third of the oesophagus in 2021 for which he was treated with neoadjuvant chemoradiotherapy, followed by McKeown oesophagectomy. At 2-year follow-up, he had developed a soft tissue swelling in the scalp, which was diagnosed as a tumour recurrence and radiotherapy was initiated.

Recent studies have demonstrated that chronic stress can enhance the development of multiple human diseases, including cancer. However, the role of chronic stress in esophageal carcinogenesis and its underlying molecular mechanisms remain unclear. This study uncovered that dysregulated cholesterol metabolism significantly promotes esophageal carcinogenesis under chronic stress conditions.
