Abstract

Introduction: In cases of stapled colorectal and ileorectal anastomosis employing surgical staplers, the “dogears”
caused by the intersection of staple lines are thought to be the location of anastomotic leak ; hence, the
importance of their excision.
Aim of work: Reevaluating the omega suture technique to resect the rectal staple line, along with those “dogears”,
within the circular stapler’s distal doughnut is the goal of the study.
Patients and methods: For the proposed technique of applying omega suture prior to firing the circular stapler,
thirty (30) patients with a variety of indications for sigmoid resection were recruited. Their data within a month
postoperatively were compared to those of thirty “correlated” patients in our database.
Results: The study group saw a lower incidence of anastomotic leak, and the two groups’ post-operative courses
were similar.
Conclusion: For improved rectal anastomosis, it is recommended to add an omega stitch to the distal (Rectal)
staple line before the circular stapler’s last firing.
