A Case of Salmonella Liver Abscess / 대한소화기학회지

Liver abscess can be caused by bacterial, parasitic, or fungal infection. Amebic abscesses are more common, but pyogenic abscesses account for three quarters of hepatic abscess in developed countries. Most common pathogens of the pyogenic liver abscess are Escherichia coli, Klebsiella pneumoniae, Bacteroides, Enterococci, Streptococci, and Staphylococci. However, liver abscess caused by Salmonella species has rarely been reported. We experienced a case of Salmonella liver abscess which improved after antibiotic therapy and percutaneous drainage. The patient was 52 years-old man who had an episode of intermittent fever, chills and epigastric pain for 2 weeks. He was diagnosed as liver cirrhosis eight years ago and diabetes three years ago. Salmonella group D, non-typhi was cultured from blood and pus from the liver respectively at the same time. With percutaneous drainage and susceptible antibiotic therapy, liver abscess decreased in size with improvements in fever and abdominal pain.

Comparison of Patients' Satisfaction for Transnasal or Transoral Endoscopy in Unsedated Patients / 대한소화기내시경학회지

BACKGROUND/AIMS: The aim of this study was to compare the patient's satisfaction and tolerance of transnasal (TN) and transoral (TO) endoscopy prospectively. METHODS: 120 patients were assigned to undergo TN (age: 49.5, M : F=65 : 55) or TO (age: 47.4, M : F=63 : 57) endoscopy according to their wishes. RESULTS: The patients' satisfaction was higher in the TN group than in the TO group (8.45 vs. 4.95, p <0.05). The degree of choking sensation, nausea, and throat soreness was lower in the TN group than the TO group. There was no difference in endoscopists' satisfaction between the two groups. The duration for TN was longer than for TO. Epistaxis and nasal pain were the common complications in the TN group. All complications were mild and were relieved spontaneously. An endoscopic examination could be completed in all patients in the TO group. In the TN group, examination failure was quite common in the early phase but the incidence decreased with increasing experience. It took the experience of at least 20 cases for the endoscopist to adapt to the TN route. CONCLUSIONS: TN endoscopy is believed to be a comfortable and safe procedure for improving the patients' satisfaction and for reducing the level of inconvenience.
