Intrasigmoid hernia is a very rare type of internal hernia and has no pathognomonic findings, making the preoperative diagnosis extremely difficult. An 83-year-old man was admitted with complaints of left lower abdominal pain and vomiting. He had neither past history of surgery, injury, abdominal attack, nor clinical or laboratory findings of strangulation ileus. Conservative treatment was not effective. Laparotomy revealed intrasigmoid hernia. The herniated small bowel was about 10 cm in length in the ileum, and was easily reduced from the mesenteric defect of the sigmoid colon. Following reduction, the hernia orifice was sutured. The patient's recovery was uneventful.
