Purpose: To evaluate the clinical results of arthroscopic repair with UU-Tension Band suture for full thickness rotator cuff tear above 4 cm sized. Materials and Methods: From January 2006 to October 2011, in 71 full thickness tears above 4 cm sized which is possible to arthroscopic repair to medial margin of greater tuberosity. The group I is 71 patients which is arthroscopic repair with UU-Tension Band suture, and the group II is 20 cases which is arthroscopic repair with simple suture. Both groups were compared with a VAS score for pain, Activity of Daily Living, UCLA score, KSS score in pre operation, 7 months, 1 year and last follow-up. Statistical analysis was performed by student t test and paired t est. Mean age was 63.2 (52~80) year old, mean follow-up was 38.4 (13~62) months. Results: The VAS scores for pain decreased from 8.1 at preoperative period to 1.6 at postoperative last follow-up period in group I (p<0.05), the score decreased from 7.6 at preoperative period to 1.8 postoperative last follow-up period in group II (p<0.05). The significant difference was not noted between two groups (p<0.05). Mean ADL scores increased from 12.5 at preoperative period to 29.0 post operative last follow-up period in group I (p<0.05), the score increased from 11.3 in pre op to 27.5 post-operative last follow-up in group II (p<0.05). The significant difference was not noted between two groups (p<0.05). The UCLA score increased from 12.9 at preoperative period to 28.7 postoperative last follow-up period in group I (p<0.05), the score increased from 13.8 at preoperative period to 30.1 postoperative last follow-up period in group II (p<0.05). The significant difference was not noted between two groups (p<0.05). In comparing of retear which was checked by MRI and ultrasound evaluated at postoperative period 7 months (mean: 27.5 weeks), the retears were 28% in the group I, and 11 shoulders out of 20 shoulders in the group II. The significant differences were noted between two groups (p<0.05). Conclusion: Arthroscopic repair with UU-Tension Band suture and simple suture for full thickness rotator cuff tear above 4 cm sized were not different clinical result between both groups. However, the significant differences were noted in point of failure rate between both groups.

Intracavitary coronary artery is variant anomalous entrance to right ventricular cavity of left anterior descending artery. Since the disease is extremely rare, there has not been any report of it in Korea and is only found in $0.2\~0.3\%$ of all CABG patients. It is very difficult to be diagnosed by preoperative coronary arteriography (CAG) and secure suture is needed for right ventriculotomy after CABG due to bleeding from right ventricle. Horizontal mattress suture with pledget has been recommended but, it could compress the myocardium surrounding ventriculotomy and result in disturbed flow of left anterior descending artery branch and perforating artery. So we used simple interrupted suture and the patient was recovered as other CABG patients without complications.

Background: The purse-string suture (PSS) is a simple and rapid wound closure method that results in minimal scarring. It has been used to treat circular or oval skin defects caused by tumor excision or trauma. However, due to obscurity, it is not widely used, especially for the head and neck. This study aimed to modify the PSS to obtain predictable and acceptable results. Methods: A total of 45 sites in 39 patients with various types of skin and soft tissue defects in the head and neck were treated with PSS. We used PDS II (2-0 to 5-0), which is an absorbable suture. Minimal dissection of the subcutaneous layer was performed. The suture knot was hidden by placing it in the dissection layer. Depending on the characteristics of the skin and soft tissue defects, additional surgical interventions such as side-to-side advancement sutures, double PSS, or split-thickness skin graft were applied. Results: All wounds healed completely without any serious complications. Large defects up to 45 mm in diameter were successfully reconstructed using only PSS. Postoperative radiating folds were almost flattened after approximately 1-2 months. Conclusion: PSS is simple, rapid, and relatively free from surgical design. Owing to the circumferential advancement of the surrounding tissue, PSS always results in a smaller scar than the initial lesion and less distortion of the body structures around the wound in the completely healed defect. If the operator can predict the process of healing and immediate radiating folds, PSS could be a favorable option for round skin defects in the head and neck.

Purpose: Seroma formation is still major complication of abdominal donor site after TRAM flap surgery in spite of various efforts to reduce seroma formation such as closed suction drain. We performed a clinical study, that quilting suture at abdominal donor site can prevent seroma formation. Methods: Between May 2002 and September 2008, we performed 600 breast reconstructions using a unilateral TRAM flap except patients who has smoking history or abdominal scar. We performed 300 breast reconstructions without quilting sutures (A: Experimental group) until January 06, and after then 300 reconstructions with quilting sutures (B: Control group). We compared total drain output (mL), time to drain removal (days), and donor site complications between two groups. Results: There were no statistical difference at BMI (p=0.28) and time to remove suction drain between two group. (A: 8.37, B: 9.69) (p=0.40) But, total drain output was reduced with quilting suture. (A: 432.5, B: 495.2) (p=0.005) And also complication rate was decreased, such as seroma formation, epigastric bulging. (A: 1%, B: 7%) (p=0.005) Conclusion: Quilting suture is a simple and reliable method to reduce seroma formation and abdominal donor site complication.

Post-intubation tracheoesophageal fistula is rare, and its management causes a serious problems to surgeons. We have experienced 4 cases in 3 patients. Simple ditcision and closure of the fistulas were done by trans-cervical approach after weaning of ventilator. The tracheal defect was closed by simple suture, and the esophageal defect was closed in two layers before a viable muscle flap was interposed between the two suture lines in order to prevent recurrence. There was one delayed tracheal stenosls and one recurrent fistula, and these complications were also managed success ully.

This paper deals with the designing of instrument for achieving surgical operation in the stomach and gullet using endoscope channel. The method used herein was to provide beads to knot suturing thread automatically. Following design rules were applied : 1) that instrument must be designed to enable surgical operator to stitch successively by only simple handling 2) that instrument must be designed to minimize insertion and extraction of endoscope. The main result from the experiment with animal stomach was that the surgical operation time was reduced and successive suture was available. Considering the requirement of operator‘s highly trained skills and the discomfort of patient in traditional suture process, the proposed design is expected to markedly improve the endoscopic suturing performance.

For a bursal-side retracted laminated rotator cuff tear, simple repair of the retracted bursal-side rotator cuff might be insufficient because the repaired tendon could remain as an intratendinous tear of the rotator cuff. We present a repair method for intratendinous rotator cuff tears using the suture-bridge technique. We believe that this method helps to preserve the remnant rotator cuff tendon without tissue damage and restores the normal rotator cuff footprint in bursal-side delaminated rotator cuff tears.

Purpose: Severe type of inverted nipple (cannot be pulled out above the areola plane by manipulation, grade III) usually cannot be corrected by a relatively simple purse - string suture technique. Most patients want to avoid visible scars. To treat the severe case and avoid visible stigma, we introduce this invisible dermal flap method. Methods: This new surgical procedure makes bilateral incisions on the sidewall of nipple and dissections vertically to free the ducts from the contracted tissues. After dissection, the tunnel is formed. We insert "dermal flaps" into the tunnel underneath nipple base. Then through - and - through sutures are performed vertically (6 o'clock and 12 o'clock positions) and the purse - string suture is added with 4 - 0 nylon. Results: We had treated 35 primary inverted nipples (grade III) in 27 patients and 13 recurrent nipples in 7 cases. The results were excellent in 45 nipples (93.7%). All but 3 recurred cases was fully or very satisfied with the results. Conclusion: This technique is effective for the correction of severe inverted nipples and recurrent cases. We can avoid the visible scars on the areola surface.

Traumatic cleft earlobes are a common problem encountered by plastic and reconstructive surgeons. Various techniques have been reported for the repair of traumatic cleft earlobes. Usually, the techniques of split earlobe repair are divided into two categories, namely straight- and broken-line repairs. Straight-line repair is simple and easy, but scar contracture frequently results in notching of the inferior border of the lobule. It can be avoided by the broken-line repair such as Z-plasty, L-plasty, or a V-shaped flap. Between April 2016 and February 2017, six patients who presented with traumatic cleft earlobe underwent surgical correction using a combination of the inverted V-shaped excision technique and vertical mattress suture method. All the patients were female and had a unilateral complete cleft earlobe. No postoperative notching of the inferior border the lobule occurred during 6-16 months of follow-up. Without the use of a broken-line repair, both the patients and the operators attained aesthetically satisfactory results. Therefore, the combination of the inverted V-shaped excision technique and vertical mattress suture method is considered useful in the treatment of traumatic cleft earlobes.
