Post-hysterectomy vaginal vault prolapse is rare complication. There are many surgical procedures to correct this problem. But abdominal colposacropexy, using Marlex mesh or Gore-Tex graft is standard procedure. We experienced one case who had repair of post-hysterectomy vaginal vault prolapse by transabdominal sacral colpopexy using Gore-Tex graft and report with brief review of literatures.

PURPOSE: To evaluate the clinical efficacy of a simplified single suture inferior retractor tightening technique in senile entropion. METHODS: Twenty patients (26 eyes) showing no severe horizontal lid laxity underwent an operation for senile entropion between April 2001 and July 2003. After a subciliary incision, the inferior retractor was identified, and repaired by reattaching the superior edge of the inferior retractor to the inferior edge of the lower tarsus using a single 5-0 Prolene suture. RESULTS: The patients were followed up for an average of 2.8 months after surgery. Five patients showed complications: two overcorrections and three recurrences of entropion. The others all showed good cosmetic and functional results. The recurred cases underwent further operation with good results. CONCLUSIONS: The simplified single suture inferior retractor tightening gave good results in patients with senile entropion without severe horizontal lid laxity. Moreover, this procedure has short operation and recovery times. In unilateral cases, more symmetric appearances were obtained compared with combined surgeries.

Between January 1979 and August 1996, resection of a primary chest wall tumor was done in 51 patients. The mean age of the patients was 36.1 years (2 to 69 years). A palpable mass was the most common symptom (32 patients, 62.7%). The tumor was malignant in 11 patients (21.6%) and benign in 40 patients (78.4%). The tumors in 32 patients (62.7%) had developed from the bony or the cartilaginous wall and in 19 patients (37.3%) from soft tissue. Thirty seven of the patients with benign tumors were treated by excision (three of the patients: wide resection and reconstruction) without recurrence or death, and they are currently free from disease. Most malignancies (8 patients) were treated by wide resection and chest wall reconstruction. Five of them are currently alive. The chest wall reconstruction with Marlex mesh, Prolene mesh, or Teflon felt was done in five of the patients with malignant tumors.

OBJECTIVETo evaluate a knitted polypropylene mesh used for mammapexy in correcting the breast ptosis.

METHODSTwenty-one patients with the mild or moderate breast ptosis were undergoing the mammapexy with a knitted polypropylene mesh. The operation was performed through the periareolar incision and a monofilament knitted polypropylene mesh was subcutaneously implanted on the surface of the gland and fixed upward.

RESULTSAll of the patients were satisfactory of the appearance with the follow-ups from 2 to 16 months. No secondary ptosis, hypertrophic scars and foreign body reactions were found.

CONCLUSIONThe above-mentioned technique could be a good, safe and reliable method for correcting breast ptosis.

PURPOSE: The feasibility of a rat choledochojejunostomy (CJ) training model was investigated, as an introductory model to microsurgery for general surgeons. METHODS: Roux-en-Y CJ was performed on 20 rats. Interrupted 10-0 prolene sutures were used to perform CJ. The animals were observed for 7 days and sacrificed and examined. RESULTS: The rats were divided into 2 groups of 10 based on surgical order. The CJ time showed a significant decrease from 36.2 ± 5.6 minutes in group 1 to 29.4 ± 5.7 minutes in group 2 (P = 0.015). The bile leakage rate was 40% in group 1 and 10% in group 2. The survival time was 5.4 ± 2.2 days in group 1 and 7 days in group 2 (P = 0.049). CONCLUSION: The rat CJ training model is a feasible introductory model for general surgeons with no previous experience in microsurgery.

PURPOSE: Various methods of scleral fixation for the cases of posterior chamber intraocular lens (PCL) dislocation or subluxation into the vitreous cavity had been developed, and in the recent year a modification of internal scleral fixation using a hollow-bore needle has been introduced. The authors endeavored to evaluate clinical usefulness of the method. METHODS: The study was conducted for four cases of PCL dislocation or subluxation. A 10-0 polypropylene suture was threaded up the internal shaft of a 30 G straight needle and retrieved. The needle containing this suture was then inserted through the bed of the partial-thickness scleral flap 1.5 mm posterior to the limbus. The loop of suture was hooked with haphic of PCL. After the needle was retracted, the haptic was captured and the suture was tied to the sclera. The same maneuver was performed for the haptic in the opposite side. RESULTS: Except for pars plana vitrectomy, time taken for the above procedure was 10~15 minutes. Postoperatively induced astigmatism of all 4 cases were less than 3 diopters on the second postoperative day. No specific complication associated with this procedure was noted. IOL remained stable without tilting or rotation 18 months after procedure. CONCLUSIONS: This modified internal scleral fixation technique must be a convenient and effective procedure for repositioning posteriorly dislocated PCL.

Fusion loss or anomaly of eye muscle and its nerve is a cause of strabismus. This induces adaptation of vergence and muscle length, the mechanisms of which are normally responsible for long-term maintenance of ocular alignment and orthophorization. To determine variability of muscle length adaptation according to age, we divided white rabbits into three groups: Group I(less than 8 weeks of age and 15000gm of body weight), Group II(10~14 weeks and 1500~2000gm), GroupIII(more than 16 weeks and 2500gm). Under local anesthesia with intravenous pentobarbital sodium, the right eyeball was fixed in exotropic position by suturing through the periosteum of the lateral canthal region with 5-o polypropylene. The muscles of left eye were not operated and served as a control. We examined electron microscopically the changes in sarcomere of the experimental right medial rectus(RMR) and right lateral rectus(RLR) after sacrificing four rabbits of each group at 1, 2 and 4 weeks, respectively. Regardless of age, when the muscle(RLR) was immobilized in the lengthened position, sarcomeres were added on and its length decreased, and when the muscle(RMR) was immobilized in the shortened position, sarcomeres were lost and its length increased. In conclusion, the study revealed that experimental extraocular muscle of rabbit is adapted in the direction to produce maximal power of its muscle and maintain ocular alignment constantly.

The previously reported repositioning methods have been known to be very difficult to be performed. A new external knotting technique was performed to reposition the dislocated intraocular lenses (IOLs). After 3-port vitrectomy, a 30 gauge injecting needle tip into which the thread end of a 10-0 polypropylene was put, was introduced into the vitreous cavity through the ciliary sulcus to make a loop having an external knot. After one haptic of the IOL was engaged into the loop, the thread was pulled back and tied to make a knot. After holding and pulling the haptic of the IOL with the intraocular forceps for proper position of the knot. Then it was sutured and fixed in sclera. The IOLs were kept in central position without complications. The final visual outcome was 0.8 and 0.3 respectively. This method might be safe and easy to correct the dislocated IOL.

PURPOSE: To compare the safety and efficacy of polypropylene and silicone Ahmed glaucoma valves (AGVs). METHODS: The medical records of 62 consecutive refractory glaucoma patients who had undergone AGV implantion from March 2003 to December 2005 were reviewed retrospectively. Among the 62 patients, 32 patients underwent polypropylene AGV implantation (group P) and the other 30 patients underwent silicone AGV implantation (group S). Postoperative IOP, the complication rate, and the success rate were compared between the two groups. RESULTS: The life-table success rates for the group P were 81.3% at 6 months and 71.2% at 12 months, and the success rates for the group S were 89.9% at 6 months and 78.6% at 12 months, showing no significant difference between the two groups. Complications, including non-tube-related complications, were observed more frequently in the group S, but there was no significant difference between the two groups. CONCLUSIONS: The silicone AGV can reduce IOP effectively but may be associated with non-tube-related complications.
