Not Applicable

Completed

Interventions: Procedure: Suturing
Procedure: Advant 55 Linear Cutter/Stapler

Brief Summary: This study is being conducted to compare surgical and patient outcomes across stapled (Group II) versus hand-sutured (Group I) groups.

Any subject that the investigator determines is not likely to be compliant during the study period
Subjects determined or suspected to engage in substance abuse, or any subject who is currently, or has in the past 6 months, undergone substance abuse therapy
