The Yoon Soon (YS) knot is a laparoscopic extracorporeal slip knot that is easy to learn and apply. Our new technique, which uses the trocar as a knot pusher, is simpler, faster, and has more tension than conventional knot methods. The YS knot will help surgeons save operative time and perform tension-controlled knot-tying during laparoscopic surgery.

PURPOSE: To compare the results of IM nailing of femur shaft fractures using trochanteric and piriformis fossa entry portal. MATERIALS AND METHODS: 37 patients were treated with IM nail using Trochanteric (Trochanter group: TG, n=17) and piriformis fossa entry portal (piriformis group: PG, n=20) and were followed from February 2004 to 2007. The outcomes were assessed based on the clinical and radiographic findings. RESULTS: The functional result, ROM and union time were similar in both groups. The alignment was similar in both groups but PG showed variable alignment in proximal 1/3. Incision was larger in PG (PG=8.7 cm, TG=5.8 cm, p<0.05) and there was a difference between overweight and normal weight group. Operative time was 95 minutes in PG, 87 minutes in TG (p>0.05), there was statistically significant difference in overweight groups (PG=125 minutes, TG=90 minutes, p<0.05). Blood loss was 313 cc in PG, 268 cc in TG and less in TG in overweight patients (p<0.05). There was 5.7degrees of varus angulation in PG, 2 nonunion cases in both groups. CONCLUSION: The femoral nail specially designed for trochanteric insertion resulted in high union rates, low complication rates similar to conventional nail and the trochanteric nail can be the alternative choice especially in proximal femur fracture and overweight patients.

The objective of this study was to report on a new surgical technique, hybrid laparoscopic myomectomy that integrates the advantages of transumbilical laparoendoscopic single-site surgery and those of isobaric laparoscopy, and the initial experience with 14 cases. All of the procedures were performed by a single surgeon who has over 18 years of experience in laparoscopic surgery and 4 years of experience in laparoendoscopic single-site surgery. All cases of hybrid laparoscopic myomectomy were completed safely and effectively without conversion to conventional laparoscopic procedure. The median operative time was 75 minutes (range, 30 to 100 minutes). No postoperative complication was observed. The findings show that hybrid laparoscopic myomectomy is a safe and feasible surgical technique, and therefore can be a feasible, minimally invasive alternative to either abdominal or laparoendoscopic single-site surgery myomectomy.

PURPOSE: We present our experience of a retroperitoneoscopic nephrectomy for a benign renal disease, and evaluate the clinical efficacy and safety of a retroperitoneoscopic nephrectomy. MATERIALS AND METHODS: The clinical results of 20 retroperitoneoscopic nephrectomies (RN) were compared with 20 open nephrectomies (ON). The surgery time, hospital stay, analgesic requirements, and complications were analysed. RESULTS: The mean operative time was 255.2 +/- 72.5 minutes for the RN patients and 161.1 +/- 22.7 minutes for the ON patients (p< 0.05). The mean hospital stay was 4.2 +/- 1.1 days for the RN patients and 9.0 +/- 1.1 days for the ON patients (p< 0.05). The analgesic dose was 80.0 +/- 23.4mg of piroxicam for RN and 240.0 +/- 26.8mg of piroxicam for the ON patients (p< 0.05). Minor and major complications occurred in 4 (20%) patients who underwent a RN and 12 (60%) patients who underwent an ON (p< 0.05). Of the 23 retoroperitoneoscopic nephrectomies, an open conversion was necessary in 3 (13%) patients. CONCLUSIONS: While operative time is longer in RN patients than ON patients, the postoperative hospital stay, analgesic requirement and complication rate are significantly lower than in ON patients. Retroperitoneoscopic nephrectomy appears to be a safe and effective alternative to a traditional open nephrectomy.

OBJECTIVE: To compare surgical outcomes of patients with myoma after robot-assisted laparoscopic myomectomy and laparoscopic myomectomy. METHODS: Retrospective chart review of 15 robot-assisted laparoscopic myomectomy (RLM) patients and 30 laparoscopic myomectomy (LM) patients at Jeju National University Hospital in Jeju between July 2009 and July 2012. Clinical features and surgical outcomes were compared. RESULTS: Surgical time was longer among RLM patinets (185.7 min vs 114.4 min). Patients undergoing robot-assisted myomectomy had a bigger size of the largest myoma, and bigger average size of the myomas. When adjusted for myoma size and number, no significant differences were noted between robotic (RLM: 24.5 min/cm) vs laparoscopic (LM: 21.5 min/cm) groups for mean operating time/total diameter. Blood loss (1.7 g/dl vs 1.95 g/dl), transfusion (0% vs 6.6%) were both no significant differences between the robotic and laparoscopic groups. CONCLUSION: When adjusted for myoma size and number, short-term outcomes were similar after robotic and laparoscopic myomectomy. Robot-assisted myomectomy is considered reliable procedure.

PURPOSE: The best option for varicocele treatment is controversial. We evaluate our experience using laparoscopic varicocelectomy & inguinal varicocelectomy, and then compared the two methods. We started this study to find the best treatment for varicocele patients. MATERIALS AND METHODS: Between July 2002 and July 2008, 168 cases (Group I) were treated with laparoscopic varicocelectomy and 157 cases (Group II) were treated with the inguinal approach. We assessed the two methods according to operative time, hospital stay, recurrence rate, complication rate, and cost effectiveness. RESULTS: The mean operative time was 30.2+/-10.9 min for laparoscopic varicocelectomy and 62.6+/-13.3 min for inguinal varicocelectomy (p<0.05). The recurrence rate was 2% for laparoscopic varicocelectomy and 8% for inguinal varicocelectomy (p>0.05). The complication rate was 10.7% for laparoscopic varicocelectomy and 12.7% for inguinal varicocelectomy (p>0.05). The cost of laparoscopic varicocelectomy was 401,870 won, but inguinal varicocelectomy was 256,480 won (p<0.05). CONCLUSIONS: The laparoscopic varicocelectomy required a shorter operative time but no superior outcomes compared to inguinal varicocelectomy. The laparoscopic approach cannot be replaced with the routine open approach but it is thought to be worth consideration in selective cases.

9.The Use of Porous Polyethylene Implants (Medpor(R)) in Cross Pattern in Case of Extensive Blow Out Fracture.
Journal of the Korean Cleft Palate-Craniofacial Association 2003;4(2):113-116
Implants are used in operative reconstruction of bony defect in case of blow-out fracture. If there is a large bony defect, the thin and flexible implants can not sustain intraorbital pressure, so it may be displaced. To prevent postoperative displacement of the implant, we tried reinforcing the center of the implant, where the intraorbital pressure was focused, piling up two pieces of porous polyethylene Implants(Medpor(R)) cross- shaped. 190 patients of large blow out fracture were divided into control group(n=95) who received classic orbital wall reconstruction and study group(n=95) to whom we inserted two small pieces of Medpor(R) one by one and covered a large defect cross shaped. We compared two groups in operative time, duration of postoperative accommodation and re-operation number. Operative time was assessed as shorter in study group(16.73+/-4.24min vs 21.40+/-5.32min, p> or =0.01). Duaration of postoperative accommodation also assessed as shorter in study group (2.05+/-0.70 weeks vs 3.00+/-1.00 weeks, p> or =0.01). There was no specific difference between two groups for re- operation number (3 vs 3, p=1.00). The method to insert two small pieces of Medpor(R) one by one and covered a large defect cross shaped shows shorter operative time and duration of postoperative accommodation than the classic method inserting large one piece of Medpor(R).

The reduction mandibular angleplasty is one of the most common aesthetic facial bone contouring surgery in the Oriental and the intraoral approach has been used commonly. However this method has some disadvantages because of anatomical restriction of operation field. We performed therefore the reduction of mandibular angle with endoscopic assistance in 15 patients of mandibular angle protrusion. Thirty patients of mandibular angle protrusion were randomly divided into control group (n=15) who received classic ostectomy and study group (n=15) who received endoscopically assisted ostectomy. We compared two groups in operative times, size of incision, duration of postoperative accommodation and satisfactory rate of doctors and patients. Size of incision was assessed as smaller in study group who received endoscopically assisted ostectomy than that of control group who received classic ostectomy on student t-test (5.50 + /-0.65 versus 4.70+/- 0.56, p< or= 0.01). Duration of postoperative accommodation was also assessed as shorter in study group on student t-test (5.07+/- 0.80 versus 4.00+/-1.00, p< or =0.01). There was no specific difference between 2 groups for operative time on x(2)-test (97.33+/- 12.22 versus 97.33+/-12.80, p=1.00). Satisfactory rate of cosmetic appearances were similar according to patients and surgeons. The postoperative course was satisfactory with smaller size of incision, shorter duration of postoperative accommodation and similar operative time and satisfactory rate of cosmetic appearances according to both patients and surgeons.
