Toothpicks are not uncommonly swallowed, and subsequently, may be impacted into gastrointestinal wall and cause morbidities, and even mortality. Therefore, the early diagnosis and immediate retrieval of an ingested toothpick is important. In many cases, endoscopic removal is attempted initially, but if this fails or a complication is encountered, surgery should be considered. The authors experienced a case of ingested toothpick penetrating the gastric wall. A 51-year-old woman visited our hospital with epigastric pain of one-week duration. Upper endoscopy revealed that the sharp end of a toothpick had been impacted into the distal antrum. Endoscopic removal using an alligator jaw forceps failed because the toothpick broke during removal and our continued attempts to extract the remnant resulted in it becoming more embedded in the stomach wall. In such circumstances, surgical treatment should be considered. However, we incised the mucosa to expose the remnant toothpick, and fortunately, we were then able to grasp and remove the toothpick using an alligator jaw forceps. We report this unusual case of a toothpick impacted in the gastric wall that was resolved endoscopically by mucosal incision.

BACKGROUND/AIMS: Preoperative diagnosis of peritoneal metastasis is extremely important to select the appropriate treatment strategy and predict the prognosis for patients with gastrointestinal cancer. However, imaging techniques have a limited capacity for detecting peritoneal metastasis. We therefore evaluated the feasibility of percutaneous ultrathin flexible peritoneoscopy in an animal model. MATERIALS AND METHODS: Percutanous ultrathin flexible peritoneoscopy was performed on two mini-pigs under general anesthesia. We punctured the abdominal wall at the anti-Mcburney and umbilical regions using a 16-gauge angiocatheter. Guidewire was inserted through the angiocatheter and we then enlarged the puncture using a biliary dilation catheter and a 6- to 8-mm balloon dilator catheter. After track formation, we inserted a 4.9-mm ultrathin endoscope into the abdominal cavity. The peritoneal cavity was examined, and peritoneal and liver biopsy was performed. The puncture was closed with a single suture. After the procedure, we monitored the general condition of the pigs for 2 weeks. RESULTS: Percutaneous ultrathin flexible peritoneoscopy was successfully performed regardless of the puncture site location. Peritoneal and liver biopsy was also successfully executed. The mean procedure time was 20 minutes. Formation of the abdominal track was not easily accomplished with standard endoscopic equipment. Nevertheless, none of the abdominal organs were injured. The post-procedure course was uneventful. Minor scarring was observed at the incision site 2 weeks after the procedure. CONCLUSIONS: Percutanous ultrathin flexible peritoneoscopy is a relatively simple and technically feasible method. However, dedicated accessories for fascial dilation should be developed to ensure the safety of human patients undergoing this procedure.

BACKGROUND AND OBJECTIVES: Sirolimus-eluting stents (SES), as opposed to bare metal stents (BMS), have been shown to markedly reduce restenosis. However, many clinical trials have excluded the subset of patients (pts) with end-stage renal disease (ESRD). The aim of this study was to evaluate the clinical outcomes following SES implantation in ESRD pts. SUBJECTS AND METHODS: We analyzed the clinical outcomes in 50 pts from our registry following SES implantation, and compared the outcomes between those with ESRD receiving SES (SES-ESRD) and BMS (BMS-ESRD), and with non-ESRD pts following SES implantation (SES-non ESRD). RESULTS: A comparison of the SES-ESRD (50 pts, 72 lesions) with BMS-ESRD groups (42 pts, 45 lesions); those in the SES-ESRD group included; diabetes 78%, hypertension 94% and age 62+/-10 years. Those in the SES-ESRD group were more likely to have diabetes (diabetes of BMS-ESRD, 57%; p=0.04). The reference vessel diameters (RVD) of the SES-ESRD group were smaller (2.76+/-0.50 mm vs. 3.05+/-0.46 mm, p<0.001), but the lesion length was longer (25.6+/-7.0 mm vs. 19.1+/-8.8 mm, p<0.001) than those of the BMS-ESRD group. The SES-ESRD group had a lower 1-year major adverse cardiac events (MACE) rate than the BMS-ESRD group (6.0% vs. 33.3%; p<0.001). There were no differences in mortality and incidence of myocardial infarction between the two groups. The incidence of target vessel revascularization decreased significantly in the SES-ESRD group (2.0% vs. 19.0%, p=0.01). From a multivariate regression analysis, the use of SES was the only significant independent predictor of MACE (OR=0.054, 95% confidence interval 0.01 to 0.26, p<0.001). A comparison with SES-non ESRD group in our total registry (644 pts, 758 lesions); MACE in the SES-ESRD group (6.0%) was higher than in the SES-non ESRD group (3.1%), but there was no statistical significance (p=0.23). CONCLUSION: Compared with BMS, SES caused an improvement in the clinical outcomes in pts with ESRD.

BACKGROUND/AIMS: Fecal microbiota transplantation (FMT) is a highly effective therapy for refractory and recurrent Clostridium difficile infection (CDI). Despite its excellent efficacy and recent widespread use, FMT has not been widely used in South Korea thus far. We describe our experience with FMT to treat refractory/recurrent CDI. METHODS: We conducted a chart review of patients who underwent FMT for refractory/recurrent CDI at Inha University Hospital, between March 2014 and June 2016. The demographic information, treatment data, and adverse events were reviewed. FMT was administered via colonoscopy and/or duodenoscopy. All stool donors were rigorously screened to prevent infectious disease transmission. RESULTS: FMT was performed in nine patients with refractory/recurrent CDI. All patients were dramatically cured. Bowel movement was normalized within one week after FMT. There were no procedure-related adverse events, except aspiration pneumonia in one patient. During the follow-up period (mean 11.4 months), recurrence of CDI was observed in one patient at one month after FMT due to antibiotics. CONCLUSIONS: FMT is a safe, well-tolerated and highly effective treatment for refractory/recurrent CDI. Although there are many barriers to using FMT, we expect that FMT will be widely used to treat refractory/recurrent CDI in South Korea.

The objectives of this investigation were to evaluate biomechanical factors in the atherosclerotic process using human in vivo hemodynamic parameters and computed numerical simulation qualitatively and quantitatively. The three-dimensional spatial patterns of steady and pulsatile flows in the left coronary artery were simulated, using a finite volume method. Coronary angiogram and Doppler ultrasound measurement of the proximal left coronary flow velocity were performed in humans. Inlet wave velocity distribution obtained from in vivo data of the intravascular Doppler study allowed for input of in vitro numerical simulation. Hemodynamic variables, such as flow velocity, pressure and shear stress of the left anterior descending coronary bifurcation site were calculated. We found that there were spatial fluctuation of flow-velocity and recirculation areas at the curved outer wall of the left anterior descending coronary artery, which were due to the differences of flow-velocity and shear stress, especially during the declaration phase of pulsatile flow. This study suggests that rheologic properties may be a part of the atherogenic process in the coronary bifurcated and curved areas.

Drug-induced immune hemolytic anemia (DIIHA) is a rare side effect of drugs. DIIHA may cause a systemic inflammatory response that results in acute multi-organ failure and death. Ceftizoxime belongs to the class of third generation cephalosporins, which are the most common drugs associated with DIIHA. Herein, we present a case of a 66-year-old man who developed fatal DIIHA after receiving a second dose of ceftizoxime. He was admitted to receive photodynamic therapy. He had a history of a single parenteral dose of ceftizoxime 3 months prior to admission. On the day of the procedure — shortly after the infusion of ceftizoxime — the patient's mental status was altered. The blood test results revealed hemolysis. Oliguric acute kidney injury developed, and continuous renal replacement therapy had to be applied. On the suspicion of DIIHA, the patient underwent plasmapheresis. Diagnosis was confirmed by a detection of drug-dependent antibody with immune complex formation. Although his hemolysis improved, his liver failure did not improve. He was eventually discharged to palliative care, and subsequently died.
