PURPOSE: The purpose of the study is to determine the efficacy and safety of needle revision of failed filtering blebs using preoperative mitomycin C (MMC) application. METHODS: We reviewed the records of 28 patients (31 eyes) who had undergone needle revision with MMC for the treatment of failed filtering bleb. MMC (0.02 mg/ml, 0.1 ml) was injected subconjunctivally one day before needle revision. RESULTS: Postopertive mean follow-up period was 42 weeks. Twenty five eyes (80.6%) were classified as surgical success which was defined as IOP less than 21 mmHg with or without any antiglaucomatous therapy. Intraocular pressure decreased from 25.5+/-6.0 mmHg before surgery to 18.6+/-5.2 mmHg at the last follow-up (p< 0.05). No serious complication was found. CONCLUSION: Our result suggested that needle revision with the preoperative subconjunctival injetion of mitomycin-C may be an effective and safe method to revive failed filtration blebs.

PURPOSE: To investigate the effects of varying the time of Mitomycin-C (MMC) subconjunctival injection before, during and after operation. METHOD: We divided rabbits into 3 groups according to injection time. Subconjunctival injections of 0.01% MMC 0.05 ml were given to the preoperative group at 6, 12 and 24 hours before operation, and to the postoperative group at 6, 12 and 24 hours after operation. The control group was given the injections during operation. Bleb formation and histologic analyses were studied for 4 weeks after operation. RESULTS For gross findings, the blebs of the preoperative and control groups were seen on the fourth day and completely formed at one week after operation, and were larger than those of the postoperative group. On the other hand, the blebs of the postoperative group were seen to have poor formation, displaying hypervascularity on the fourth day and disappearing one week after operation. For histologic findings, the proliferation of collagen fibers and the undifferentiation of fibroblasts observed in the preoperative and control groups were almost identical. But, the proliferation of collagen fibers and well-differentiated fibroblasts were seen to increase in the postoperative group, so aqueous flow was obstructed at week 3. CONCLUSIONS: Subconjunctival injections within 24 hours before or during glaucoma filtration surgery were better for bleb formation and preservation than those administerd after surgery.

A 62-year-old woman with ischemic heart disease, hypertension and hypercholesterolemia had developed spinal cord infarction after off-pump coronary artery bypass (OPCAB). The incidence of postoperative neurological complications is well known to be less in OPCAB than that of conventional coronary bypass surgery. Furthermore, spinal cord infarction is an uncommon clinical event after coronary bypass surgery. Here we report a case of spinal cord infarction following OPCAB, discuss possible mechanism of spinal cord infarction with relate literatures.

PURPOSE: Laparoscopic appendectomy isused as a three port technique for appendectomy. In children, single port laparoscopic appendectomy is difficult because they have a small peritoneal cavity for manipulation of laparoscopic instruments. We performed transumbilical laparoscopic assisted single port appendectomy (hybrid appendectomy) in children. METHODS: From March 2010 to July 2012, we performed transumbilical laparoscopic assisted single port appendectomy in 53 children. We made a vertical incision to the umbilicus approximately 1.5 cm, and a wound retractor (Applied Medical Resources Co., Ltd., Rancho Santa Margarita) was placed in the umbilical incision, and appendix exteriorized the extraperitoneum through the wound retractor. Appendectomy was performed conventionally. We had no conversion cases for laparotomy. RESULTS: A total of 53 patients, 29 females and 24 males, with a mean age of 8.5+/-2.0 years were enrolled in this retrospective study. The mean operative time was 29.4+/-9.4 minutes. There was no occurrence of complication or mortality. BMI was 17.8+/-4.9 kg/m2. And mean hospital stay was 3.2+/-1.0 days. CONCLUSION: In children, transumbilical single port laparoscopic appendectomy is technically difficult because they have a small peritoneal cavity. However, transumbilical laparoscopic assisted single port appendectomy (hybrid appendectomy) appearsto be a safe and effective technique for use in children, which allows for achievement of nearly scarless surgery.

PURPOSE: To report a case of inadvertent anterior chamber and cornea stromal injection with high dose antibiotics and steroids during cataract operation. METHODS: During cataract operation on a 78 year-old female patient, high dose gentamicin (20 mg/0.5 ml) and dexamethasone (2 mg/0.5 ml) were inadvertently injected into the anterior chamber and cornea stroma when making cornea edema for sealing of the incision sites. Anterior chamber irrigation with balanced salt solution (BSS) was immediately administered. On postoperative day one, extensive cornea edema was noted, and best-corrected visual acuity was 0.2. Descemet's membrane folds were observed around the corneal incision sites. Topical 5% NaCl and 1% prednisolone were started. RESULTS: Four weeks postoperatively, corneal edema began to reduce significantly. At four months postoperatively, corneal edema fully resolved, and best-corrected visual acuity was 0.8. However, some Descemet's membrane folds still remained, and a decrease in the number of endothelial cells was noted by specular microscope. CONCLUSIONS: In this case involving anterior chamber and cornea stromal injection with high dose antibiotics and steroids, immediate anterior chamber irrigation with balanced salt solution seemed an appropriate management, and the patient's long-term visual acuity appears good. To prevent such mistakes, precise labeling of all solutions and use of different syringe needles should be considered.
