ABSTRACT
Laparoscopy is useful for minimally invasive detailed examination of patients with suspected gastrointestinal perforation. Here we report a case of gastrointestinal perforation of unknown cause that was diagnosed laparoscopically as perforation of the sigmoid colon by a toothpick. The patient was a 41-year-old woman. She presented with a chief complaint of left lower abdominal pain and CT showed a small amount of free air in the peritoneal cavity, so emergency surgery was performed. Laparoscopy revealed a foreign body penetrating the sigmoid colon. After mobilization of the sigmoid colon, the surgical technique was switched to minilaparotomy and partial sigmoid colectomy was performed. The foreign body that had penetrated the intestine was identified as a toothpick. We later learned that the patient had become intoxicated while eating at a yakiniku barbecue restaurant 7 days prior to the operation, and she guessed that she had accidentally consumed a toothpick stuck in an onion. Gastrointestinal perforation by a toothpick is rare and is difficult to diagnose preoperatively because toothpicks appear transparent on X-ray imaging. In this case, laparoscopy was useful for identifying the site and cause of perforation as well as the extent of leakage into the peritoneal cavity.
ABSTRACT
We treated a total of 67 patients for mamushi viper (Gloydius blomhoffii) bite during a 10-year period between 2007 and 2016. The mean age of the patients was 68 years, with those aged ≥ 60 years accounting for about 80％ of all patients. Most injuries occurred between July and September in rice fields and other cropland, or in the patients’ homes. Except for 1 severe case who developed a marked thrombocytopenia immediately after the incident, the remaining 66 patients were included in the analysis. All patients received inpatient care, with a mean hospital stay of 6.8 days. There was a significant positive correlation between the size of the swelling at the bite site and the length of hospital stay. Kidney dysfunction occurred in 3 patients, 1 of whom died. The mean time to the largest swelling was 21.8 h while the mean time to the highest creatine phosphokinase level was 2.6 days. The more severe cases were more likely to be have been treated with mamushi antitoxin while 2 of the 3 patients with kidney dysfunction, including the 1 fatality, were not, suggesting that the use of mamushi antitoxin is essential in severe cases. We also report a very rare case of mamushi viper bite complicated by thrombocytopenia.
