The purpose of this study is to evaluate the ventricular conduction abnormalities, especially RBBB, observed electrocardiographically after surgical closure of VSD. The present study population consists of 92 patients with VSD who were surgically corrected at the Hanyang University Hospital during 6 years period from Jan. 1985 to Dec. 1990. We reviewed their clinical records including surgical notes and EKG findings before and after operations. The results of the study were as follows: 1) Male to female ratio was 1.1:1 (48:44) 2) Out of a total of 92 cases of VSD, 65cases(70.7%)were perimembranous type and 27 cases (29.3%)were subarterial type. 3) The normal preoperative EKG findings were seen in 22 patients, LVH in 21 patients, BUH in 47patients, and RVH in 3 patiens. 4) A transatrial approach was performed in 55 cases, right ventriculotomy with or without resection of muscles in right ventricle in 13 cases, and pulmonary arteriotomy alone in 24 cases. 5) The right bundle branch block after operation developed in 33 patients out of the 65 patinets with perimembranous defect and 5 patients out of the 27 patients with subarterial defects. Postoperative RBBB developed more frequently in perimembranous defect than in subarterial defect. 6) Postoperative RBBB occured in 31.8% of the patients with normal preoperative EKG findings, 23.8% with preoperative LVH, 52.1% with BVH and 66.7% with RVH. Postoperative RBBB was more frequently observed in the patients group with preoperative BVH or RVH than the patients with normal or LVH. 7) Postoperative RBBB was observed in 84.6% after right wentriculotomy, in 43.6% after right atriotomy and in 12.5% with pulmonary arteriotomy alone.

PURPOSE: Many diagnostic modalities have been used for diagnosis of gastroesophageal reflux disease (GERD). Feeding materials during esophageal pH monitoring may interfere the result of examination and esophageal pH monitoring can not diagnose GER in case of alkaline reflux. The purpose of our study is to evaluate whether scintigraphy can substitiute 24 hr pH monitoring in children with GERD. METHODS: From March 2002 to June 2003, 23 patients (12 boys and 11 girls, mean age 27 months) who have been admitted to Hanyang University Hospital presented with GER symptoms (recurrent vomiting, cough, chest pain, irritability) were included in the study. Scintigraphy and 24 hr pH monitoring were performed in all patients. RESULTS: Six out of the 23 patients (26.1%) had evidence of GER on 24 hr pH monitoring, whereas nine of 23 patients (39.2%) exhibited GER by scintigraphy. Two out of the 23 patients could not be tested because of irritability. Three (14.3%) patients had evidence of GER on both 24 hr pH monitoring and scintigraphy, three (14.3%) patients on only 24 hr pH monitoring, six (28.6%) patients on only scintigraphy, and nine (42.9%) patients had no evidence of GER on both methods. No correlation was observed between 24 hr pH monitoring and scintigraphic results by Fisher's exact test (p=0.523) or Kendal's tau (t=0.678). CONCLUSION: The results of this study demonstrated that there was no correlation between 24 hr pH monitoring and scintigraphy. Therefore these modalities could be used as complementary tests to diagnose GERD.

PURPOSE: To analyze stereopsis change before and after inferior oblique weakening surgery. METHODS: We retrospectively reviewed the medical records of 31 patients who had undergone inferior oblique weakening surgery. The factors analyzed included sex, age at surgery, preoperative and postoperative visual acuity (VA), time from first detection to surgery, degree of inferior oblique overaction (IOOA), primary/secondary IOOA, exotropia/hypertropia, bilaterality, and type of surgery. RESULTS: Eighteen patients with a mean age 7.3 ± 3.1 years exhibited stereopsis of 60 arc seconds or better before surgery and 17 had stereopsis better than 60 arc seconds after surgery. Postoperatively, stereopsis improved in 13 patients and deteriorated in 9. Better preoperative VA and the absence of superior oblique underaction were associated with better preoperative stereopsis. Better preoperative VA, postoperative VA, and the presence of head tilt were associated with better postoperative stereopsis. Unilateral inferior oblique weakening surgery and accompanying hypertropia were associated with improved stereopsis, while the absence of hypertropia was associated with deteriorated stereopsis. CONCLUSIONS: In this retrospective study, 58.1% of patients tended to have bifoveal fixation. When a vertical deviation is present in the primary position due to unilateral IOOA, IO weakening surgery can be expected to improve binocular function.

PURPOSE: To determine the anatomic variations that can lead to optic nerve damage during the sugical treatment of posterior paranasal sinus lesions MATERIALS AND METHODS: two hundred optic nerves of 100 persons were examined using ostiomeatal unit CT (OMU CT). The anatomical features of this nerve and posterior paranasal sinuses were classified into four types : the optic nerve adjacent to the sphenoid sinus without indentation of the sinus wall (type 1); the optic nerve adjacent to the sphenoid sinus, causing indentation of the sinus wall (type 2); the optic nerve passing through the sphenoid sinus (type 3); and the optic nerve adjacent to the sphenoid sinus and posterior ethmoid sinus (type 4). Bony dehiscence around the optic nerve and pneumatization of the anterior clinoid process were also evaluated. RESULTS: The anatomical classification of the optic nerve and posterior paranasal sinuses was as follows : type 1, 1326 (66%); type 2, 60 (30%); type 3, 6 (3%), and type 4, 2 (1%). Bony dehiscence around the optic nerve had developed in 58 cases (29%) and pneumatization of the anterior clinoid process in 13 (6.5%). These conditions were most common in type 3 optic nerve, and second most common in type 2. CONCLUSION: The 2 and 3 optic nerve, bony dehiscence around the optic nerve and pneumatization of the anterior clinoid process are the anatomic variations that can lead to optic nerve damage during the surgical treatment of posterior paranasal sinus lesions. To prevent optic nerve damage, these factors should be carefully evaluated by OMU CT.

PURPOSE: Recently, as the number of transobturator tape (TOT) procedures has increased, recurrence after this procedure has been frequently reported. However, there are no standard guidelines for treatment. We describe our experience with shortening the previously implanted tape in patients with recurrent stress urinary incontinence after the TOT procedure. MATERIALS AND METHODS: We enrolled 10 women who underwent shortening of the previously implanted tape and were followed up for 3 years. Shortening of the previously implanted tape was done by a figure-eight suture with 1-0 Prolene. One year after TOT shortening, we investigated continence status, patient satisfaction by means of a questionnaire, maximal flow rate (Qmax), and postvoid residual urine volume. Three years after TOT shortening, we evaluated continence status and patient satisfaction. RESULTS: The mean period of TOT shortening was 4.2 months (range, 1-12 months) after the TOT procedure. One year after TOT shortening, 7 patients showed complete dryness, 2 patients showed improvement, and 1 patient reported failure. Eight patients were very satisfied or satisfied with the 1-year result after TOT shortening. The mean preoperative and postoperative Qmax were 23.8 and 26.7ml/s, respectively, and there was no significant difference. Three years after TOT shortening, 6 patients showed complete dryness, 2 patients showed improvement, and 2 patients reported failure. Among them,1 had failed from 1 year after TOT shortening and the other had shown 1 year of complete dryness. Eight patients were very satisfied or satisfied and 2 patients were dissatisfied with the 3-year result after TOT shortening. CONCLUSION: Most of the patients who underwent TOT shortening reported satisfaction as well as improvement of incontinence after a 3-year follow up. Therefore, we suggest that TOT shortening may be recommended primarily in patients with recurrent stress urinary incontinence after the TOT sling procedure.
