Reoperation*

Study on 87 patients of cholelithiasis (52 males, 35 females) who were reoperated in Hospital No 7, Hi D­ng (1996 - 2000) has shown that: Ultrasonography and X-ray should be performed before and post-operation. The patients, who were reoperated many times, should be indicated for choledoco enteroanastomosis.

Repeated surgery of the lumbar spine after lumbar discectomy was not uncommon. Total 817 cases of lumbar disorders were carried out surgical intervention in author's clinic from Jan. 1993. to May 1997. Among them, 82 cases were reoperated cases after lumbar disc surgery. The causes, methods and outcome of reoperation were reviewed. The most common causes of reoperation was epidural adhesion, and the most frequent method of reoperation was the interbody fusion with adhesiotomy. Epidural fibrosis was the major problem and must be studied forward for preventing reoperaion.

Various surgical techniques for Hirschsprung's disease including total colonic aganglionosis have been performed with similar results. The type of redo pull-through procedure is determined by the cause of failure and the type of primary pull-through.

Authors analysed the clinical characteristics and the surgical results of rhegmatogenous retinal detachment in 70 patients(71 eyes) who were operated GNUH from Feb. 1990 to Feb. 1992. The clinical characteristics of rhegmatogenous retinal detachment were as follows. The result was myopia(39.4%) as the most common associated ocular finding, one break(57.7%) as the number of break, two quadrants(33.8%) as the extent of retinal detachmenthole(53.5%) as the type of break and superior temporal portion(56.3%) and anterior portion including equator(83.1%) as the location of break. The success rate of first operation was 87.3% and the overall success rate of rhegmatogenous retinal detachment maintained anatomical attachment above 6 months and exeluded 3 cases of refused reoperation was 92.3%. The type of break extent of detachment and duration of detachment were not influenced to surgical success rate statistically(P>0.05). The most common cause of first operative failure was proliferative vitreoretinopathy(57%).

When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage previously placed and re-do interbody fusion with lower risks compared to revision surgery via previous passage. However, there is still some difficulty in retrieving the interbody cage from the intervertebral space because of no spacious passage, subsidence, and uncontrolled movable cage. In this study, we introduce our experience that we removed failed interbody cage more easily with only the simple additional steps of making a taphole and fixing the cage using a thread-tipped stick.

PURPOSE: To evaluate the efficacy of re-recession or extirpation of inferior oblique (IO) muscle in recurrent or undercorrected IO overaction (IOOA). METHODS: We reviewed the records of 26 patients (33 eyes) with the recurrent or undercorrected IOOA after the graded recession of IO muscle, who underwent re-recession or extirpation of IO muscle, and was followed up for at least 6 months. We performed extirpation of IO muscle overacting larger than +2 after 14 mm recession of IO muscle or larger than +3 after 10 mm recession of IO muscle. In case of +2 IOOA after 10 or 8 mm recession of IO muscle, we carried out 14 mm re-recession of IO muscle. IOOA under +1 was defined as a successful case after re-operation. RESULTS: Thirty one of 33 eyes (93.9%) were corrected successfully after re-operation; 24 eyes with extirpation of IO muscle (96.0%) and 7 eyes with 14 mm re-reccession of IO muscle (87.5%) were successful. CONCLUSIONS: One of the advantages of graded recession of IO muscle is that additional re recession or extirpation of IO muscle can be preformed if needed. Extirpation or 14 mm re-recession of IO muscle was effective re operation procedure to correct a recurred or undercorrected IOOA.

For undercorrected esotropia after bilateral medial rectus(MR) recession, we performed unilateral or bilateral MR rerecession, unilateral rerecession or marginal myotomy of the recessed medial rectus muscle combined with lateral rectus(LR) resection, or unilateral LR resection. The correction of deviation was 15 delta in unilateral 2.0mm MR rerecession. Bilateral 2.0mm MR rerecession corrected 20 to 25 delta of esodeviation, but undercorrection was noted in one case. With unilateral 2.0mm rerecession or marginal myotomy of the recessed medial rectus muscle combined with 5.5mm or 8.0mm LR resection, the correction of deviation was 26 to 29 delta, and there was no under- or overcorrection. The corrective effect of this procedure was therefore greater and more stable than that of bilateral 2.0mm MR rerecession. Unilateral 8.0mm LR resection performed 3 months after bilateral MR recession showed correction of 15 delta, whereas the same procedure performed 3 weeks after bilateral MR rerecession showed correction of 24 delta. Unilateral LR resection procedure seems to be more efficacious for residual esotropia if performed as soos as possible within 3 months after sufficient bilateral MR recession or rerecession.

PURPOSE: To evaluate of the effect of bilateral medial rectus recession in the patients who showed large angle (>50 prism diopters, PD) infantile esotropia as comparing small angle (reoperation rate were compared between large angle group (>50 PD, 14 patients) and small angle group (reoperation rate was 35.71% (5 of 14) in large angle and 14.81% (8 of 54) in small angle but statistical difference was not found (p=0.12). CONCLUSIONS: The success rate and reoperation rate of bilateral medial rectus recession in large angle infantile esotropia were not different as compared with those of small angle infantile esotropia. So bilateral medial rectus recession is adequate to initial procedure in the treatment of large angle infantile esotropia.
