A 30-year-old woman involved in a car crash is brought into the emergency department. Her blood pressure is 90/60 mm Hg, pulse rate is 120 bpm, and respiration rate is 18 breaths per minute. On peritoneal lavage, she is noted to have free blood in the peritoneal cavity. At the time of exploratory laparotomy, a liver laceration is noted, and there is a 2.5-cm-diameter contusion to an area of small bowel. How should the small-bowel contusion be treated?
