The researchers assessed the results of endoscopic stapler-assisted diverticuloesophagostomy for Zenker's diverticulum, with emphasis on patient satisfaction and subjective relief of symptoms.
They reported their findings in the February issue of Surgery.
A retrospective cohort analysis was performed on all patients operated on at the authors' institution from 1997 to 2000. A total of 30 patients (22 men, mean age 72 years) were identified.
Patients' charts were reviewed with respect to intraoperative and postoperative complications.
The severity of preoperative and postoperative symptoms by patient self-assessment was compared by means of a 4-point scale (0-3) on a standardized questionnaire.
In addition, patient satisfaction (poor, fair, moderate, high) was assessed.
The patients were followed-up for a mean of 13 months.
|96% of patients were highly satisfied with the procedure.
No major intraoperative or postoperative complications were observed.
The team found that the most frequent preoperative symptoms were regurgitation of undigested food and dysphagia for solid consistencies (87%).
Both of these preoperative symptoms were improved from a mean preoperative score of 2.2 and 2.7, to 0.1 and 0.4, respectively.
Postprandial coughing (32%), halitosis (21%), and globus sensation (32%) were less common, but also significantly improved.
All patients, apart from 1 (96%), were highly satisfied with the procedure.
Dr Sandro J. Stoeckli, of the University Hospital Zurich, concluded on behalf of fellow authors, "Endoscopic stapler-assisted treatment of Zenker's diverticulum offers a very low complication rate, a very high degree of symptom relief, and patient satisfaction."
