Abstract
BACKGROUND: The treatment of Zenker's diverticulum has been shifted from open cricopharyngeal myotomy and rigid endoscopy to the use of flexible endoscopy. Few studies evaluate general surgeon's performance of flexible endoscopic management of Zenker's diverticulum as the majority are performed by gastroenterologists. The objective of our case series is to show that general surgeons trained in surgical endoscopy can perform this procedure with favorable outcomes. METHODS: A retrospective review of peroral cricopharyngeal myotomies performed at Spectrum Health hospital in Grand Rapids, Michigan by a single surgical endoscopist between the 2018 and 2021 was conducted. The primary outcome was the improvement of dysphagia. Intra-procedural complications, post-procedural complications, hospital length of stay, time to oral intake, and recurrence were also evaluated. Age, sex, body mass index, diverticulum size, and procedure time were abstracted. Median (ranges) and frequencies (percentages) are used to describe the patient population and outcomes. RESULTS: Forty patients were included in the study. Median age was 74 years old (60-95) with a male predominance (n = 27, 67.5%). Median BMI was 28 kg/m2 (18-43), average procedure length of 64 min (41-119), diverticulum size of 28 mm (19-90), and average length of stay of 0.9 days (0-8). There were no intra-procedural complications. All patients had a post-procedural esophagram prior to initiation of diet. Esophageal leak was the only complication that occurred, which was found on post-procedural esophagram (n = 5). Only two patients had clinical sequelae. All leaks closed without additional surgical intervention. The majority of patients had their diet resumed and discharged the same day of the procedure. Frequency of recurrence was 17.5% (n = 7). CONCLUSION: Our study demonstrates that general surgeons trained in endoscopy can perform endoscopic myotomies for Zenker's diverticula on a wide range of sizes, with favorable patient outcomes, and few complications.
