How much progress have we made?: a 20-year experience regarding esophageal stents for the palliation of malignant dysphagia

Summary Esophageal stents are widely used for the palliation of malignant esophageal obstruction. Advances in technology have made esophageal stenting technically feasible and widespread for such obstruction, but complications remain frequent. We present outcomes of a large cohort undergoing esophageal stent placement for malignant esophageal obstruction at a tertiary care cancer center. Patients who underwent placement of esophageal stents for malignancy-related esophageal obstruction between 1 January 2001 and 31 July 2020 were identified. Exclusion criteria included stents placed for benign stricture, fistulae, obstruction of proximal esophagus (proximal to 24 cm from incisors), or post-surgical indications. Patient charts were reviewed for demographics, procedure and stent characteristics, complications, and follow-up. A total of 242 patients underwent stent placement (median age: 64 years, 79.8% male). The majority, 204 (84.3%), had esophageal cancer. During the last two decades, there has been an increasing trend in the number of esophageal stents placed. Though plastic stents were previously used, these are no longer utilized. Complications are frequent and include early complications of pain in 68 (28.1%) and migration in 21 (8.7%) and delayed complications of recurrent symptoms of dysphagia in 46 (19.0%) and migration in 26 (10.7%). Over the study period, there has not been a significant improvement in the rate of complications. During follow-up, 92 (38%) patients required other enteral nutrition modalities after esophageal stent placement. No patient, treatment, or stent characteristics were significantly associated with stent complication or outcome. Esophageal stent placement is an increasingly popular method for palliation of malignant dysphagia. However, complications, particularly pain, migration, and recurrent symptoms of dysphagia are common. Almost 40% of patients may also require other methods of enteral access after esophageal stent placement. Given the high complication rates and suboptimal outcomes, removable stents should be considered as first-line in the case of poor palliative response.

Esophageal Stent in Sleeve Gastrectomy Leak Treatment: Observations Based on a Challenging Surgical Case and Literature

Gastric leak is a serious complication of sleeve gastrectomy with a well-documented morbidity and mortality. Depending on the series the leak rate ranges between 1 and 5%. The treatment of sleeve gastrectomy leak is still challenging. Different procedures have been described in management of gastric leak, both surgical and endoscopic. The treatment of gastric leaks depends on the extent of the staple-line leak, the site of the leak and its association with stenosis. As published data are limited, there are no still standardized guidelines on best treatment. One of the most commonly used option in the treatment of gastric leak is esophageal stent. Its success rate reaches 70–80% but it is burdened by some complications. Stent migration is the most common complication in the placement of esophageal stent.We present a challenging surgical in which case the use of an esophageal stent for the treatment of a sleeve gastrectomy leak gained the resolution of the leak but was complicated by bowel obstruction due to migration of the stent.

544 MANAGEMENT OF ACUTE ANASTOMOTIC COMPLICATIONS AFTER IVOR-LEWIS ESOPHAGECTOMY

Anastomotic leak (AL) and conduit necrosis (CN) are among the most serious surgical complications after esophageal resection. Endoscopic, radiological and surgical methods are used in their treatment. The aim of this paper is to evaluate the results of the treatment of acute anastomotic complications after Ivor-Lewis esophagectomy in a single high-volume center. Methods We performed a retrospective audit of a consecutive cohort of 815 patients undergoing transthoracic esophagectomy with intrathoracic esophago-gastric anastomosis from 2005 to 2019. AL was graded according to Esophagectomy Complications Consensus Group recommendation. Results There were 79 patients with AL and 6 patients with CN (10%). AL type I, II and III was diagnosed in 33 (39%), 25 (29%) and 27 (32%) patients, respectively. Esophageal stent was used in 40 patients. Primary surgical revision (with/without stent insertion) was performed in 14 patients. Reoperation was necessary overall in 25 patients (29%). Seventeen patients (20%) ended-up with esophageal diversion. Treatment with esophageal stent was successful in 28/40 patients (70%). Endoscopic vacuum-therapy was successfully used in three patients for peristent leak after stent extraction. Mortality of severe AL (type II and III) was 10/52 patients (19%). Conclusion Successful management of acute anastomotic complications requires early diagnosis and an individual treatment approach with the use of endoscopic, radiological and surgical methods. The primary attempt for anastomosis preservation using esophageal stent is desirable. Considering the clinical condition and CT finding, we recommend not to hesitate with surgical revision with debridement and drainage of pleural cavity and mediastinum. If primary therapy fails, life-saving procedure is the esophageal diversion.
