This case involves a sixty-five-year-old female patient who underwent an endoscopy and colonoscopy after suffering from chronic anemia of unknown etiology. According to the medical record, the physician mentions that during the procedure, there was technical difficulty due to restrictions of movement of the colon and that a perforation of the sigmoid colon was suspected. He attributed the failure to sigmoid looping and noted a perforation at 18 cm while removing the scope camera. The patient had to undergo a sigmoid resection with end colostomy via the Hartmann procedure. As a consequence of the fair amount of peritoneal irritation and fluid in the pelvis, a decision was made not to attempt primary anastomosis.
