Percutaneous endoscopic gastrostomy (PEG) is a common and safe procedure for enteral nutrition. There are few reports concerning its complications. We managed a 31-y-old bedridden case with punched out duodenal perforation without inflammation, from which the tip of the PEG tube protruded. Simple x-ray and computed tomography showed incarceration of the balloon in the duodenal bulb and extravasation of the tip of the tube. We performed simple closure with omental patching for duodenal perforation. Postoperative gastrointestinal fiberscopy on the 11th day revealed scar phase. Some PEG tubes have a balloon, which can prevent the removal of the tube, fix the position of the tube, and prevent the leakage of gastric contents from fistula. However, in our case, the inflated balloon was transferred into the duodenal bulb according to gastric strong peristalsis. This pathophysiologic mechanism is the same as ball bulb syndrome, which is known as gastroduodenal obstruction by incarceration of the gastric submucosal tumor. There is a risk of wedging of the inflated balloon of the PEG tube and perforation of the duodenum. We must not insert the tube too deeply, must not continue to inflate the balloon for a long time, and must check its position using a stethoscope, simple x-ray examination, or ultrasound.

Background: Blood transfusion therapy (BTT), which represents transplantation of living cells, poses several risks. Although BTT is necessary for trauma victims with hemorrhagic shock, it may be futile for patients with blunt traumatic cardiopulmonary arrest (BT-CPA). Materials and Methods: We retrospectively examined the medical records of consecutive patients with T-CPA. The study period was divided into two periods: The first from 1995-1998, when we used packed red cells (PRC) regardless of the return of spontaneous circulation (ROSC), and the second from 1999-2004, when we did not use PRC before ROSC. The rates of ROSC, admission to the ICU, and survival-to-discharge were compared between these two periods. Results: We studied the records of 464 patients with BT-CPA (175 in the first period and 289 in the second period). Although the rates of ROSC and admission to the ICU were statistically higher in the first period, there was no statistical difference in the rate of survival-to-discharge between these two periods. In the first period, the rate of ROSC was statistically higher in the non-BTT group than the BTT group. However, for cases in which ROSC was performed and was successful, there were no statistical differences in the rate of admission and survival-to-discharge between the first and second group, and between the BTT and non-BTT group. Conclusion: Our retrospective consecutive study shows the possibility that BTT before ROSC for BT-CPA and a treatment strategy that includes this treatment improves the success rate of ROSC, but not the survival rate. BTT is thought to be futile as a treatment for BT-CPA before ROSC.
