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.

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.

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.

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.

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 evaluate the usefulness of a polypropylene non-woven sheet as a spacer graft for the correction of lower lid retraction METHODS: Fifteen New Zealand white rabbits were randomized into three groups. Polypropylene non-woven sheets were implanted between the tarsus and lower lid retractor via a transcutaneous approach (Group 1), a transconjunctival approach (Group 2), or a transconjunctival approach with amniotic membrane transplantation (Group 3). Numerous large pores were made in the sheet with a 21-gauge needle before implantation. Rabbits were sacrificed serially after 1, 2, 4, 6, and 8 weeks in each group. Gross and histologic examinations were performed. RESULTS: In Group 1, the polypropylene sheets stayed in place well, without any exposure on gross observation except at 2 weeks. In Group 2, the conjunctival wound was not healed on the polypropylene sheet, and the sheet was exposed to the ocular surface and extruded gradually. In Group 3, the conjunctival wound was well healed on the surface of polypropylene sheet, and the sheet remained stationary at 4, 6, and 8 weeks on gross examination. Histologic examinations showed gradual fibrovascular ingrowth into the polypropylene sheets in Groups 1 and 3, but not in Group 2, in which only severe inflammatory infiltrations were observed. CONCLUSIONS: The polypropylene non-woven sheet is a good candidate for a spacer material in lower lid retraction operation, and either the transcutaneous approach or the use of an amniotic membrane is necessary for best postoperative outcome.

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.

Indirect inguinal hernia containing an ovary is a rare condition, especially in adult women who do not have any other genital tract anomalies. In addition, inguinal hernia containing an ovary and endometriosis is exceedingly rare. In the present report, we describe a case of indirect inguinal hernia containing an ovary, fallopian tube, and endometriosis. Laparoscopic repair was performed successfully using polypropylene mesh for the treatment of the inguinal hernia.
