Outpatient endoscopic Zenker diverticulotomy.

OBJECTIVE

Staple-assisted, endoscopic Zenker diverticulotomy has been shown to decrease both cost of treatment and length of convalescence when compared with the standard open approach. Although the endoscopic technique is generally considered to be safe, the feasibility of outpatient endoscopic Zenker diverticulotomy has never been reported.

METHODS

Retrospective cohort study.

METHODS

All endoscopic Zenker diverticulotomy procedures performed at Oregon Health and Science University (Portland, OR) between 1998 and 2002 were reviewed. The study group was limited to patients whose surgeries were planned on an outpatient basis. Medical charts were reviewed for indications, demographics, operative findings, complications, and resolution of symptoms.

RESULTS

Of the 51 patients who underwent endoscopic, staple-assisted Zenker diverticulotomy, 40 were treated with the intent of outpatient management. Thirty-two cases were primary surgeries, and eight cases were revision treatments. The average patient age was 68 years (age range, 35-91 y), and the mean follow-up period was 5.9 months (range, 1-37 mo). Eight (20%) complications were noted in the study group. Intraoperative complications included 3 patients (7.5%) with mucosal disruptions. These patients underwent uneventful suture repair of small hypopharyngeal mucosal tears encountered intraoperatively and were temporarily observed in the hospital. One patient was admitted for postoperative urinary retention and another for fever and tachycardia 48 hours after surgery. One patient sustained a myocardial infarction. The remainder of patients were fed immediately and discharged home on the day of surgery. Two patients (5%) had iatrogenic tooth fracture.

CONCLUSIONS

Appropriately selected patients undergoing endoscopic, staple-assisted Zenker diverticulotomy can be managed safely on an outpatient basis. Intraoperative complications, such as a mucosal disruption, warrant conversion to inpatient monitoring.
