ABSTRACT We used a retrospective chart review to analyze revision endoscopic carbon dioxide (CO2) laser and staple repairs of recurrent Zenker diverticulum (ZD).
The medical records of patients with recurrent ZD after primary endoscopic repair were selected. The chart data included method of repair (CO2 laser or stapler), demographics (age and sex), defect size (in centimeters), preoperative and postoperative symptoms, and complications. Patients' dysphagia was graded on a modified Functional Oral Intake Scale from 1 to 4 (1 being normal intake and 4 being severely limited intake or gastrostomy tube dependence). Regurgitation was also graded on a 1-to-4 scale (1 being no regurgitation and 4 being aspiration).
A total of 148 consecutive patients with ZD were treated with endoscopic repair between 2000 and 2010. Twelve of these patients had revisions after failed primary endoscopic management procedures, all done with the stapler. Eight revision surgeries were performed by CO2 laser, and 4 by stapler repair. No difference was noted in patient age or defect size (laser, 3.06-cm defects; stapler, 2.75-cm defects). The length of hospital stay and the time to oral intake for the patients who had a revision stapler procedure were significantly greater (p values of 0.029 and 0.009) than those for the patients in the primary stapler procedure group. Better postoperative regurgitation scores were noted for patients who had a CO2 laser procedure.
Secondary endoscopic repair for ZD recurrence is an effective treatment method. Better symptom outcomes were observed with secondary CO2 laser repair than with stapler revision. Patients with revision stapling had longer hospital stays and a longer time to oral intake than did patients with primary staple repairs.

    ABSTRACT: The treatment of choice of Zenker's diverticulum is the rigid endoscopic mucomyotomy. At our ENT department, we usually perform an endoscopic mucosal suture after the myotomy. We diagnosed 49 patients and treated 39 patients between 2003 and 2013 due to a Zenker's diverticulum. We used the classification of Brombart to determine the size of the diverticulum. Surgery was performed as an endoscopic LASER mucomyotomy with mucosal sutures or as an open approach with diverticulectomy and myotomy. Patients were phoned to ask for their complaints postoperatively. The symptoms were classified using a visual scale from 0 (no complaint) until 10 (same or more complaints than before the surgery). The distribution of the diverticulum's size was: 6 patients Brombart I, 11 patients Brombart II, 14 patients Brombart III and 18 patients Brombart IV. 10 patients did not undergo surgery. With 33 patients, we performed an endoscopic operation and 6 patients underwent an open approach. The scale of postoperative complaints was the following: 20 patients (0/10), 12 patients (1/10 or 2/10), 3 patients (3/10), 1 patient (6/10) and 1 patient (10/10). None of the patients suffered from severe complications such as mediastinitis. In 85 % of the cases, an endoscopic approach could be performed. Postoperatively, 94 % of the patients did not have any or just mild complaints. The risk of severe complications or recurrence of the diverticulum is low. The mucosal suture might reduce the risk of infections.

    ABSTRACT: The purpose of the present study is to evaluate long-term outcome and patients' satisfaction after endoscopic therapy of Zenker's diverticulum (ZD) and to analyze the results of the stapler technique in comparison with the application of the carbon dioxide (CO2) laser. A retrospective cohort study with outcome analysis of patients undergoing endoscopic cricopharyngeal myotomy with either stapler or CO2 laser between October 2000 and December 2010 by a single surgeon was performed. Patient's medical charts were reviewed with respect to symptoms before intervention, intra and post operative complications, reasons for the choice of endoscopic technique, and postoperative relief of symptoms. Long-term follow-up was acquired by a standardized self-assessment questionnaire. Seventy-four patients (51 men, 23 women) with a median age at operation of 74 years (range 45-93 years) were enrolled in this study. Forty-five patients underwent endoscopic repair of a ZD with stapler, 29 patients with CO2 laser. The mean follow-up was 4.7 years. We did not observe significant differences for intra and post operative complications, hospital stay, time until normal oral food intake, need for revision, and long-term subjective symptom relief between the two groups. Overall complication (12 %) and recurrence rate (11 %) for the endoscopic techniques were low. Endoscopic surgery had also a high success rate in recurrence cases (87.5 %). According to our study, the most important factor for the success rate of endoscopic treatment was the intraoperative exposure of the ZD. The endoscopic minimally invasive approach is a safe and effective treatment modality and can be considered as the treatment of choice for primary and recurrent ZD. The intraoperative exposure is decisive for the technique applied and the long-term success.

    ABSTRACT: Several reports have recently been published regarding dysphagia in very elderly patients, and centenarian dysphagia patients have become more common in Japan. The aim of this study was to assess the prognosis of dysphagia in very elderly patients. Participants were 24 centenarian dysphagia patients. For each patient, we collected information on age, care level, past medical history, and changes in oral intake according to the Functional Oral Intake Scale (FOIS). Patients were divided into two groups based on the mode of food intake at the time of transfer or discharge: the per oral-only group (the PO-only group, i.e., oral intake alone) and the tube feeding-dependent group (the TF-dependent group, i.e., combination of oral intake and tube feeding, or tube feeding alone). In both groups, the FOIS score decreased significantly from pre-hospitalization to the time of transfer or discharge (p = 0.006 for both). The FOIS score at initial assessment was higher in the PO-only group with the TF-dependent group (p = 0.0004). Furthermore, the frequency of a FOIS score of 4 at initial assessment was significantly higher in the PO-only group, and the frequency of a FOIS score of 1 was significantly higher in the TF-dependent group (p = 0.0006). These findings collectively suggest that oral intake can be recovered if the FOIS score is ≥4 at initial assessment, is difficult if the score is 1, and may be possible with a FOIS score of 2.
