Surgical management of esophageal stenosis due to ingestion of corrosive substances.

BACKGROUND: Corrosive ingestion is a significant challenge for healthcare systems. Limited data are available regarding the best treatments, and there remains a lack of consensus about the optimal surgical approach and its outcomes. This study aims to review the current literature and show a single institution's experience regarding the surgical treatment of esophageal stenosis due to corrosive substance ingestion. METHODS: A retrospective review that accounted for demographics, psychiatric profiles, surgical procedures, and outcomes was performed. A systematic review of the literature was performed using PubMed. RESULTS: In total, 27 surgical procedures for esophageal stenosis due to corrosive substance ingestion were performed from 2010 to 2019. Depression and drug abuse were diagnosed in 30% and 22% of the included patients, respectively. Esophagectomies and esophageal bypasses were performed in 13 and 14 patients, respectively. No 30-day mortality was recorded. CONCLUSION: Surgical intervention either by esophagectomy or esophageal bypass results in durable relief from dysphagia. However, successful clinical outcomes depend on a high-quality multidisciplinary network of esophageal and thoracic surgeons, intensivists, psychologists, psychiatrists, and nutritional teams.

Primary malignant melanoma of the esophagus: a rare and aggressive disease.

Primary malignant melanoma of the esophagus is an uncommon tumor, with approximately 300 cases having been reported thus far. The purpose of this study was to describe a case of a 60 year-old man with a 10 month history of progressive dysphagia and thoracic pain, the investigations of which led to a diagnosis of primary malignant melanoma of the esophagus. The patient underwent a transhiatal esophagectomy with subcarinal lymphadenectomy, and isoperistaltic gastric tube replacement of the esophagus. Nine months after surgery, he developed ischemic colitis, and metastasis in the mesentery was diagnosed. His disease progressed and he died one year after the esophagectomy. A review of the literature was performed.

Preoperative gastric acid secretion and the risk to develop Barrett's esophagus after esophagectomy for chagasic achalasia.

INTRODUCTION: The aim of this study was to determine the contribution of preoperative gastric secretory and hormonal response, to the appearance of Barrett's esophagus in the esophageal stump following subtotal esophagectomy. METHODS: Thirty-eight end-stage chagasic achalasia patients submitted to esophagectomy and cervical gastric pull-up were followed prospectively for a mean of 13.6 +/- 9.2 years. Gastric acid secretion, pepsinogen, and gastrin were measured preoperatively in 14 patients who have developed Barrett's esophagus (Group I), and the results were compared to 24 patients who did not develop Barrett's esophagus (Group II). RESULTS: In the group (I), the mean basal and stimulated preoperative gastric acid secretion was significantly higher than in the group II (basal: 1.52 vs. 1.01, p = 0.04; stimulated: 20.83 vs. 12.60, p = 0.01). Basal and stimulated preoperative pepsinogen were also increased at the Group I compared to Group II (Basal = 139.3 vs. 101.7, p = 0.02; stimulated = 186.0 vs. 156.5, p = 0.07. There was no difference in preoperative gastrin between the two groups. Gastritis was present during endoscopy in 57.1% of the Group I, while it was detected in 16.6% of the Group II, p = 0.014. CONCLUSIONS: Barrett's esophagus in the esophageal stump was associated to high preoperative levels of gastric acid secretion, serum pepsinogen, and also gastritis in the transposed stomach.

Barrett's esophagus (BE) and carcinoma in the esophageal stump (ES) after esophagectomy with gastric pull-up in achalasia patients: a study based on 10 years follow-up.

BACKGROUND: Subtotal esophagectomy and gastric pull-up with cervical anastomosis is the main treatment for advanced achalasia. This surgical technique has been associated to esophagitis and also Barrett's epithelium following esophagectomy. AIM: To analyze late clinical, endoscopic, and pathologic findings in the esophageal stump (ES) mucosa after subtotal esophagectomy in patients treated for advanced chagasic achalasia. METHODS: 101 patients submitted to esophagectomy and cervical gastroplasty were followed-up prospectively for a mean of 10.5 +/- 8.8 years. All patients underwent clinical, endoscopic and histopathological evaluation every 2 years. Gastric acid secretion was also assessed. RESULTS: The incidence of esophagitis in the esophageal stump (45.9% at 1 year; 71.9% at 5 years, and 70.0% at 10 years follow-up); gastritis in the transposed stomach (20.4% at 1 year, 31.0% at 5 years, and 40.0% at 10 or more years follow-up), and the occurrence of ectopic columnar metaplasia and Barrett's Esophagus in the ES (none until 1 year; 10.9% between 1 and 5 years; 29.5% between 5 and 10 years; and 57.5% at 10 or more years follow-up), all rose over time. Gastric acid secretion returns to its preoperative values 4 years postoperatively. Esophageal stump cancer was detected in the setting of chronic esophagitis in five patients: three squamous cell carcinomas and two adenocarcinomas. CONCLUSION: (1) Esophagitis and Barrett's esophagus in the esophageal stump rose over time. (2) These mucosal alterations and the development of squamous cell carcinoma and adenocarcinoma are probably due to exposure to duodenogastric reflux, and progressively higher acid output in the transposed stomach.
