Acute Appendicitis is the most frequent acute pathological abdominal illness needing immediate surgery. The laparoscopic appendectomy (LA) has become more popular and is advised as the first course of treatment, particularly for female, obese, and elderly patients.LA can also give surgeons a greater field view and identification of other abdominal organs that can have different pathologies that could mimic the symptoms of acute appendicitis.The most crucial step in preventing major complications such postoperative bleeding, peritonitis, sepsis is sealing the mesoappendix. Due to this circumstance, surgeons are looking for alternative treatments for LA. The best technique for sealing mesoappendix should be affordable, practical, safe, and easy to apply technically. Extracorporeal sliding knots, intracorporeal ligations, endo-loops, nonabsorbable polymer clips (Hem-o-lock clips), hand-made loops, and Ligasure usage, and bipolar cautery division are some of the techniques utilized at LA to seal mesoappendix. According to studies, each of these techniques is secure and practicable.5 In this study, there is a comparative study between using Bipolar diathermy as a source of sealing and other mechanical closure techniques for mesoappendix To assess effect of energy source sealing of mesoappendix by using Bipolar diathermy in comparison to mechanical closure by clips as regard outcome and complications.
