SECONDARY outcome

Timeframe: This outcome was assessed at the completion each necrosectomy procedure per participant. At the completion of all necrosectomy procedures for all participants, an overall mean percent necrotic material removed from the WOPN per procedure was calculated.

At the completion of each necrosectomy procedure the Investigator will visually inspect the WOPN cavity endoscopically and estimate the percent of necrosis that was removed from the cavity using EndoRotor. For each procedure, the initial amount of necrosis in the WOPN cavity is considered 100%.

SECONDARY outcome

Timeframe: 21 +/- 7 Days

Population: All participants who had a completed SF-36v1 Questionnaire at both Baseline and the 21 Day Follow-up visit.

The SF-36v1 questionnaire measures functional health and well-being from a patient's point of view. The questionnaire assess eight health domains including: Physical Functioning, Role Limitations due to Physical Health, Role Limitations due to Emotional Problems, Energy/Fatigue, Emotional Well Being, Social Functioning, Pain, and General Health. Participants were asked to complete the questionnaire at the Baseline Visit and then again at the 21 Day Post Necrosectomy Follow-up Visit. The results of the questionnaire from the 21 Day Post Necrosectomy Follow-up Visit were then compared to those of Baseline for improvement. Numeric scores for each health domain are reported on a scale of 0-100 with improvement demonstrated by a higher score than baseline. Statistically significant improvement is denoted by differences in Baseline and 21 Day Follow-up Visit scores that have a p-value \< 0.05.
