우측 개흉술을 통한 개심술은 심방중격 결손증, 승모판막 질환에서 이루어질 수 있다. 최근에 본원에서는 AESOP 3000을 이용하여 흉강경적 심방중격 봉합술, 승모판막 성형술, Maze 수술, 최소침습적 관상동맥 우회술 등을 시행하고 있다. 하지만, 흉강경을 이용한 대동맥 판막 치환술에 대해서는 현재 국내 보고가 없는 실정이다. 본원에서는 31세 여자 환자에게서 AESOP 3000을 이용한 흉강경적 대동맥 판막 치환술을 성공적으로 시행하였기에 문헌 고찰과 함께 보고하는 바이다.

The Nuss procedure for the correction of Pectus Excavatum (PE) is associated with intense postoperative pain. Our strategy to control early postoperative pain is to combine epidural with intravenous analgesia. Our aim was to analyse our pain control strategy by reviewing all the PE cases treated at our institution. Sixty consecutive patients, aged between 12 and 26 years old, received the PE operation at our institution from January, 2007 to September, 2010. The median age was 16 (12-27) with a male/female ratio of about 7/1. An epidural catheter was employed in all the cases, with 38 patients (63%) requiring additional drugs to control pain, which remained in place for 74 hours (72-96). The pain score was higher in male patients, but lower in those younger than 16 years old. Moreover, patients that consumed benzodiazepines had a significant decrease in cumulative opioid intake (P = 0.0408). Both gender and age had an impact on pain control, while we noticed a synergistic effect between opiates and tranquillizers.

We report our experience of a concurrent robot assisted distal gastrectomy and partial nephrectomy for synchronous early gastric cancer and renal cell carcinoma. A 55-year-old female patient was diagnosed with early gastric cancer on screening endoscopy. Abdominal computed tomography showed an incidental right renal cell carcinoma. Robot assisted distal gastrectomy was performed, followed by partial nephrectomy. The final pathological examination showed signet ring cell carcinoma within the lamina propria and renal cell carcinoma with negative resection margins. The patient showed no evidence of recurrence at 6-months. A robot-assisted combined operation could be a treatment option for early stages of synchronous malignancies.

위식도역류질환은 서구에선 매우 유병률이 높으며 우리나라에서도 식생활의 서구화로 인해 유병률이 증가하고 있다. 최근 최소침습수술이 발달함에 따라 복강경을 이용하여 수술할 경우 미용효과, 단기재원기간 및 일상생활로의 조기복귀 등의 장점이 있어 장기적인 약물치료보다는 최소침습법에 의한 수술의 시행이 늘어날 것으로 예상된다. 저자들은 복강경을 이용하여 횡격막 탈장 및 탈장을 동반한 위식도역류성 질환에 대해 시행한 니센 위저추벽성형술 및 콜리스 위성형술 치험을 바탕으로 수술수기를 중심으로 문헌고찰과 함께 보고하는 바이다.

Minimally invasive techniques for pediatric inguinal hernia repair have been evolving in recent years. We applied the laparoscopic method to repair pediatric inguinal hernia using the techniques of sac transection and intra-corporeal ligation. Between November 2008 and August 2010, 67 pediatric patients (47 boys and 20 girls) with inguinal hernias were included in this study. Postoperative activities, pain, and complication were checked prospectively at regular follow-up. One patient presented with clinically bilateral hernia, and three patients had metachronous hernias. Thirty-two cases out of 63 patients with unilateral hernias had a patent processus vaginalis on the contralateral side. Mean operation time was $35{\pm}11.4$ minutes for unilateral hernias and $43{\pm}11$ minutes for bilateral hernias. There were no intra-operative complications. One patient had a small hematoma on the groin postoperatively, which subsided spontaneously in a week. Recurrence and metachronous hernia were not found at follow up. In summary, laparoscopic inguinal repair in children is safe, easy to perform and has an additional advantage of contralateral exploration. Further studies should include long term follow-up.

Purpose: To retrieve the retracted flexor tendon, additional incision and wide dissection are conventionally required. We introduce minimal - incision tenorrhaphy using 1 cm - length incision and minimal dissection. Methods: Transverse incision about 1 cm - length is made over the level of retracted tendon. Nelaton's catheter is advanced into tendon sheath from distal primary laceration wound to emerge proximally through the incisional wound. Catheter is sutured to proximal tendon in end - to - end fashion. By gently pulling the catheter, retracted tendon is delivered to distal wound. Tenorrhaphy with core suture and epitendinous suture is then carried out. Results: This retrieving technique provides minimal incision, minimal dissection, minimal bleeding, minimal injury to tendon end, and shorter operation time with preservation of vincula tendinum and pulley system. Conclusion: In case of flexor tendon rupture with retraction, this operative method is believed to allow reliable and effective tenorrhaphy and excellent postoperative outcomes.

흉강내시경을 이용한 교감신경 절단술은 수장부 다한증뿐만 아니라 액와부 다한증에 대해서도 효과가 좋다고 알려져 있다. 이전에 R2, 3, 4교감신경 절단술의 여러 가지 조합 방법들과 다르게 R4, 5절단 방법 효과를 알아보고자 한다. 액와부 액취증 없이 과다한 땀이 나는 환자들을 대상으로 2002년 2월부터 8월까지 2mm 흉강내시경 이용하여 5예의 흉강경 교감신경절단술 시행하였다. 모든 환자들 수술 결과에 만족하였고 과다한 땀은 더 이상 없었다. 총 5예 중, 3예에서(60%) 보상성 다한증을 경험하였는데, 그중 1예만(20%) 의미 있게(불편한 정도는 아니지만) 보상성 다한증을 허리 및 허벅지에 보였다. 액와부 다한증에 대한 치료로 R4, 5 교감신경절단술은 효과적인 치료 방법으로 생각한다.

Various surgical techniques, such as endoscopic surgery and robotic surgery, are developed to optimize the esthetic outcome even in operations for malignancy. A modified face-lift or retroauricular approach are used to minimize postoperative scarring. Recently, robot-assisted surgery is being done in various fields and considered as favorable treatment method by many surgeons. However its high cost is a nonnegligible fraction for many patients. On the other hand, endoscopic surgery, which is cheaper than robotic surgery, is minimally invasive with contentable neck dissection. Although it is a difficult technique for a beginner surgeon due to its limited operation view, we suppose it as an alternative method for robotic surgery. Herein, we report two cases of endoscopic neck dissection via retroauricular incision with a discussion regarding the pros and cons of endoscopic neck dissection.

Purpose: Laparoscopic wedge resection of gastric submucosal tumor may be difficult in case of the endophytic mass or the mass located unreachable area such as cardia, and intragastric approach can be useful. We would present the experiences of the intragastric wedge resection. Materials and Methods: There were 7 patients diagnosed as gastric submucosal tumor and underwent the intragastric wedge resection at Surgery, Chungnam National University Hospital. We reviewed medical record. Results: There were 3 male and 4 female. Mean age was 65 years-old (57~73). Mean body mass index was 26.28 kg/$m^2$ (21.28~35.30). Location of lesions was 4 cardia, 2 fundus and 1 midbody, respectively. Mean operation time was 83.6 minutes (70~105). All patients were healed without any complication. Mean postoperative hospital stay was 5.4 days (4~6). Mean size was 2.7 cm (2.3~3.8). Pathologic finding was 5 gastrointestinal stromal tumor and 2 leiomyoma. Conclusions: The single incision intragastric wedge resection of gastric submucosal tumor is feasible and acceptable, especially in mass of gastric upper part.

Objective : Lumbar spinal stenosis is a common degenerative spine disease that requires surgical intervention. Currently, there is interest in minimally invasive surgery and various technical modifications of decompressive lumbar laminectomy without fusion. The purpose of this study was to present the author's surgical technique and results for decompression of spinal stenosis. Methods : The author performed surgery in 57 patients with lumbar spinal stenosis between 2006 and 2010. Data were gathered retrospectively via outpatient interviews and telephone questionnaires. The operation used in this study was named central decompressive laminoplasty (CDL), which allows thorough decompression of the lumbar spinal canal and proximal two foraminal nerve roots by undercutting the lamina and facet joint. Kyphotic prone positioning on elevated curvature of the frame or occasional use of an interlaminar spreader enables sufficient interlaminar working space. Pain was measured with a visual analogue scale (VAS). Surgical outcome was analyzed with the Oswestry Disability Index (ODI). Data were analyzed preoperatively and six months postoperatively. Results : The interlaminar window provided by this technique allowed for unhindered access to the central canal, lateral recess, and upper/lower foraminal zone, with near-total sparing of the facet joint. The VAS scores and ODI were significantly improved at six-month follow-up compared to preoperative levels (p<0.001, respectively). Excellent pain relief (>75% of initial VAS score) of back/buttock and leg was observed in 75.0% and 76.2% of patients, respectively. Conclusion : CDL is easily applied, allows good field visualization and decompression, maintains stability by sparing ligament and bony structures, and shows excellent early surgical results.
