This was a retrospective descriptive study of 105 patients who underwent postoperative endoscopy of the hepatobiliary tract through the T-tube tract. The first 42 consecutive patients (Group A) underwent the procedure from May 1997 to June 1998 wherein a bronchoscope (Pentax 4.9 mm.) was used. The next 63 consecutive patients (Group B) underwent the procedure from July 1998 to August 1999 and a choledoscope (Olympus CHF type P-20) was used. In Group A, 40 patients had retained stones and in Group B, 48 patients had retained stones, for a total of 88 (84%) cases with residual stones diagnosed. The average number of sessions were 5.2 and 2.7 for Group A and Group B, respectively. The clearance rate was 95 percent for Group A and 91.7 per cent for Group B

BACKGROUND: Accurate knowledge of mainstem bronchial lengths are required to prevent malpositioning of double lumen endobronchial tubes (DLT). Therefore we evaluated the length of the mainstem bronchus in Korean adults who had no abnormalities in both mainstem bronchus. METHODS: Two-hundred Thirty-seven patients were composed of One-hundred one males and One- hundred Thirty-six females who underwent elective surgery. After an endotracheal tube was placed, we measured the length from the upper incisor to the tracheal carina, the right mainstem bronchial carina, and the left mainstem bronchial carina using a fiberoptic bronchoscope. RESULTS: The lengths from the upper incisor to the carina of a male and female were 26.8 +/- 1.8 cm and 23.6 +/- 1.9 cm respectively, and the correlations between their length and height are significant for male and female (r = 0.32, P < 0.01 and r = 0.56, p < 0.0001). The lengths from the upper incisor to the right mainstem bronchial carina of male and female were 29.0 2.0 cm and 25.3 2.2 cm respectively, and the correlations between their length and height are significant for male and female (r = 0.39, P < 0.0001 and r = 0.59, P < 0.0001). The lengths from the upper incisor to the left mainstem bronchial carina of male and female were 32.0 2.1 cm and 28.5 2.1 cm respectively, and the correlations between their length and height are significant for male and female (r = 0.45, P < 0.0001 and r = 0.60, P < 0.0001). CONCLUSIONS: We found that as the height of patients increased, the length from the upper incisor to the carina, the right mainstem bronchial carina, and the left mainstem bronchial carina increased. Nevertheless,it should be understood that the length of DLT insertion at any given height is still normally distributed, and correct DLT positioning should always be confirmed fiberoptically after the initial placement.

Plastic bronchitis is a rare disorder characterized by the formation of extensive, obstructing endobronchial casts. It is associated with asthma and complex cardiac defects such as those requiring the Fontan procedure. The treatment of plastic bronchitis comprises conventional therapy involving spontaneous expectoration and bronchoscopic removal and specific therapy with several new drugs. Herein, we describe the cases of 2 patients diagnosed with plastic bronchitis accompanied with a different underlying disease, which were treated with inhaled corticosteroid and low-dose oral clarithromycin.

BACKGROUND: Tracheal hamartoma is a very rare cause of upper airway obstruction. Its clinical features can mimic medical conditions, such as bronchial asthma, chronic bronchitis, and so on. CASE: This report presents the case of a 65 year old man whose major symptom was dyspnea. We found a tumor in his distal tracheal lumen, and the tumor was removed with success using rigid bronchoscope. The tumor was histologically proven to be a hamartoma, and his symptoms were much improved. CONCLUSION: It is important to distinguish it from other conditions because medical management is often not helpful. surgical correction-with or without thoracotomy-is inevitable.

BACKGROUND: Double lumen endobronchial tube and single lumen tube with bronchial blocker are most frequently used tubes for one lung anesthesia. This study compared the double lumen endobronchial tube with the single lumen tube with bronchial blocker to determine whether there were objective advantages of one over the other during one lung anesthesia. METHODS: Sixty patients were randomly assigned to one of two groups. Thirty patients were intubated with a left-sided double lumen endobronchial tube, and thirty patients were intubated with a single lumen tube with bronchial blocker. Each group was subdivided into two groups with a person intubating (i,e, certified anesthesiologist or resident) to compare the easiness of intubation according to the type of tube. Fiberoptic flexible bronchoscope was used in all patients. The following were studied 1) time required to position each tube until satisfactory placement achieved, 2) frequency of malposition after initial placement with fiberoptic bronchoscopy, 3) surgical exposure ranked by surgeons blinded to type of tube used, 4) easiness of tracheobronchial toilet (TBT). RESULTS: 1) Statistically significant differences were observed in time required to place each tube by resident(double lumen tube 5.73+/- 0.48 min. versus single lumen tube with bronchial blocker 4.18+/-0.70 min (P<0.05) and in easiness of TBT (double lumen tube 18/30 versus single lumen tube with bronchial blocker 27/30) (P<0.05). 2) No differences were observed in time required to position each tube by anesthesiologist, the frequency of malposition and surgical exposure. CONCLUSIONS: Single lumen tube with bronchial blocker is better in easiness of intubation by resident and in easiness of TBT than double lumen endobronchial tube. But the selection of two tubes depends upon type of surgery and familiarity of each tube by the anesthesiologist.
