A 25-year-old man was admitted to the emergency department after falling off his bicycle. He was hit by the bicycle's handle bar into the left side of the abdomen. The clinical examination revealed a fit young man who had only a scratch (abrasion) on the abdominal wall left of the umbilicus. Hemodynamically he was normal and alert and referred to intense pain at the abrasion site. The abdomen was soft, without signs of peritoneal irritation while sensitivity was only at the point of the abrasion. Laboratory tests, including white blood cells, liver enzymes, and amylase, were normal. The abdominal X-ray in upright (standing) position did not reveal the presence of free intraperitoneal air. Abdominal ultrasound did not reveal any solid abdominal organ injury nor the presence of free intraperitoneal fluid. The pain was attributed to hematoma of the rectus abdominis muscle pricey below the abrasion which was revealed by ultrasound.\nThe pain of the young man was gradually worsening and was mostly described diffusely throughout the whole abdomen. The abdomen remained soft and tender without signs of peritoneal irritation. We proceeded to the administration of per os contrast material and CT abdomen. The CT scan revealed the presence of sufficient amount of free intraperitoneal contrast but did not allow the clarification of the exact point of escape. The free contrast material was detected at the left side of the abdomen, at the area of the descending colon but mainly in the pelvis (). The intraluminal contrast had even reached up the level of the transverse colon.\nThe patient was taken to the operating room for exploratory laparotomy immediately after the CT scan (4 hours after the arrival at the emergency department and about 4.5 hours after the time of injury). Intraoperatively, fecal peritonitis due to isolated rupture of jejunum 30 cm from the ligament of Treitz was revealed. The rupture was at the center of an extensive jejunum serous layer fissure giving the picture of “blow out” perforation. At the jejunal mesentery there was minimal bruising. Multiple washings of the peritoneal cavity were performed with normal saline, and the restoration of jejunal injury was done with partial resection and end-to-end anastomosis ().\nThe postoperative course of the patient was uncomplicated, and he was discharged on the 6th postoperative day. 9 days later he returned with clinical and radiological signs of ileus that led us to the operating room 48 hours later due to deterioration of his clinical picture. The cause of the ileum was adhesions, so we proceeded to lysis of adhesions. The anastomosis was normal without leakage. Five days later the patient was discharged, and a year later he is still free of symptoms.
A nearly 7-year-old boy, with no relevant past history, visited our emergency department with abdominal pain and swelling after a fall from his bike. Whilst riding his bike, he had fallen and his abdomen had landed on the handlebar. Immediately after the accident, his mother noticed a swelling where the handlebar had hit his abdomen. They visited the general practitioner on call who subsequently sent him to our emergency department. Apart from pain, he had no other complaints. On physical examination, he seemed to be not ill and he was haemodynamically stable. Examination of the abdomen showed a circular contusion of the skin several centimetres below the umbilicus just on the right of the midline (Fig. ). On palpation, a clear defect of the rectus fascia could be felt. There were no signs of peritonitis suggesting an enteral lesion. He was admitted for observation and discharged the following morning. He was scheduled for surgery 1 week later. During the operation, a skin-line incision was performed over the fascia defect, revealing a rupture of the musculus rectus abdominis, as well as a total rupture of the right rectus fascia (Fig. ). The rectus sheath was closed with a continuous Vicryl suture. The muscle defect was approximated with interrupted Vicryl sutures. The skin was closed intracutaneously. He was discharged the following day and recovered uneventfully.
