Sigmoid Colon Perforation by Foreign Body Insertion

Sigmoid colon perforation caused by foreign body insertion is an uncommon but clinically significant presentation. We present a case of a 38-year-old male farmer who presented with acute abdominal pain and signs of peritonitis resulting from a foreign body-related sigmoid colon perforation. The patient reported progressively worsening abdominal pain, febrile illness, and constipation for four days. Clinical evaluation revealed abdominal rigidity, tenderness, and a dilated rectum with bloody discharge. Imaging studies confirmed pneumoperitoneum, indicative of bowel perforation. During the exploratory laparotomy, an 8cm longitudinal tear was identified on the rectosigmoid junction. Primary repair and diversion ileostomy were performed. Postoperatively, psychiatric consultation revealed rectal insertion of a foreign body to relieve constipation.
