This case involved a thirty-five-year-old male requiring partial colectomy. The individual required partial removal of the descending (left-sided) colon due to inflammation associated with his ulcerative colitis. The individual still had abdominal pain, bloody stools, and general malaise months after recovering from surgery. He was mostly complaining of left lower quadrant abdominal pain. After examining the pathology report, it was found that the tissue taken during surgery was not inflamed and was consistent with ascending (right-sided) colon histologic features. The surgeon removed the inappropriate portion of the patient’s colon, which required additional surgery.
