  • Esophagectomy has a high morbidity rate, mainly related to pulmonary complications. The respiratory morbidity of open esophagectomy is high, ranging from 6% to 10%. This high morbidity is partially responsible for the 6∼15% mortality rate of esophagectomy. Many techniques of esophagectomy without thoracotomy have been described since the initial report of Orringer and Sloan. Endoscopic microsurgical dissection of the esophagus was clinically introduced in 1989. Endoscopic microsurgical dissection of the esophagus was developed as a minimally invasive procedure that avoids thoracotomy and provides precise vision during the operation in order to reduce mediastinal trauma and to improve the peri- and post-operative situation. A 20 year-old women who accidentally swallowed about 150 cc of glacial acetic acid underwent an esophagectomy using the operating mediastinoscopy, cervical esophagogastric anastomosis, pyloromyotomy, and feeding jejunostomy tube placement for esophageal stricture. The postoperative course was uneventful and the patient was discharged on the 17th postoperative day. Our clinical experience shows that endoscopic microsurgical dissection of esophagus is a safe and feasible method because it offers excellent optical control and enables the surgeon to operate in a minimally invasive manner.

  • 편측 성대마비의 음성개선을 위하여 현재까지 알려진 치료방법은 teflon 또는 silicone 주입술, 외과적 성대 내전술, 갑상연골 성형술, 신경재식술, 등이 있으며, 근래까지는 Teflon 또는 Gelform 주입술이 제일 효과적인 방법이라 알려져 있으나, 이는 음의 높낮이 조절능력의 한계가 있고, 신경재식술의 결과 역시 만족스럽지 못한 경우가 많다. 따라서 저자는 발성기능의 생리학적인 측면에서, 보다 효과적인 음성개선의 방법을 찾기 위하여, 사람의 후두와 비교적 유사한 특성을 가진 개를 사용하여 실험을 하였다. 반회신경을 절단하여 편측 성대 마비를 유발한 뒤, 동측의 유일한 외전근인 후윤상피열근을 절제후 절단된 신경을 문합하여, 성대의 외전근 작용의 소실과, 발성시에 주로 작용하는 내전근만의 작용을 유도하여, 공동운동의 차단과, 내전운동의 향상을 기대하였다. 본 실험에 앞서, 임의적으로 신경을 자극시킬 수 있는 신경자극기와, 주위조직으로부터 신경만을 분리하여 자극할 수 있는 전극을 개발하여 사용하였으며, 또한 성대의 발성음을 임의대로 유발시킬 수 있는 생체 내 후두발성 모형(in vivo laryngeal phonation model)을 Moore(1987, 1988)등이 발표한 모형을 토대로 자체 개발하여 사용하였다. 실험은 13마리의 개를, 반회신경 절단군(3 마리), 반회신경 절단 및 후윤상피 열근 절제군(3 마리), 후윤상피열근 절제군(3 마리), 반회신경 문합 및 후윤상피 열근 절제군(4 마리)등으로 나누어 실험하였으며, 3 개월 후, 현수후두경, 후두 내시경, videolaryngoscopy, 신경자극 검사 등으로 성대의 내전운동 및 위치 변화의 관찰, 발성음의 음향분석 및 갑상피열근의 형태학적 변화를 관찰하여 다음과 같은 결과를 얻었다. 1. 반회신경 절단군과 반회 신경 절단 및 후윤상피열근 절제군은, 수술후 3 개월에 성대의 움직임이나 각도의 변화가 없었으며, 음향분석 결과 발성음이 아닌 잡음만이 포착되었다. 즉, 절단된 신경의 문합 없이 후윤상피열근 절제 만으로는 음성개선은 기대할 수 없었다. 2. 후윤상피열근 절제군에서는 수술 후 3 개월에 정상적인 성대의 내전운동이 관찰되었으며, 음향분석상 기본주파수 동요율 및 발성음의 강도는 약간의 증가를 보였다. 즉, 반회신경이 절단되지 않은 상태에서 후윤상피 열근 만을 절제하면, 발성음의 변화는 거의 없었다. 3. 반회신경을 절단후 문합하고 후윤상피열근을 절제한군 에서는 수술후 3 개월에, 성대의 정상적인 내전운동을 보였고, 음향분석상 수술직후에는 잡음만이 포착되었으나, 3 개월 후에는 잡음이 아닌 발성음을 들을 수 있었으며, 이 발성음의 기본주파수 및 강도는 수술전보다 감소되어 있었으나, 기본주파수 동요율은 증가되어 있었다. 즉 이 술식으로 인한 뚜렷한 발성음의 향상이 있었다. 이상의 결과로 미루어, 편측 신경 절단으로 인한 성대마비시, 절단된 신경을 봉합하고 성대의 유일한 외전근인 후윤상피열근을 절제하면, 공동운동의 차단과, 내향운동의 향상으로, 음성개선에 효과적이라고 사료되었으며, 이 방법이 편측 성대마비 환자의 효과적인 음성개선의 치료방법의 하나로 응용될 수 있으리라 생각된다.

  • The clinical significance of hepatic resection for gastric metastases is controversial, even though hepatic resection has been widely accepted as a modality for colorectal metastases. Very few patients with gastric hepatic metastases are good candidates for hepatic resection because of multiple bilateral metastases, extrahepatic disease, or advanced cancer progression, such as peritoneal dissemination or extensive lymph node metastases. Therefore, several authors have reported the clinical significance of hepatic resection for gastric metastases in a small number of patients. Considering the present results with previous reports. The number and distribution of tumors in hepatic metastases from gastric cancer was considered based on the present and previous reports. Several authors have reported significantly better survival in patients with metachronous metastasis than in those with synchronous disease. However, metachronous hepatic resection necessitates the dissection of adhesions between the pancreas, liver, and residual stomach to prepare for Pringle's maneuver. Patients with unilobar liver metastasis, and/or metastatic tumors <4 cm in diameter may be good candidates for hepatic resection. Synchronous metastasis is not a contraindication for hepatic resection. Most of the long-term survivors underwent anatomic hepatic resection with a sufficient resection margin. After hepatic resection, the most frequent site of recurrence was the remaining liver, which was associated with a high frequency of mortality within 2 years. A reasonable strategy for improvement in survival would be to prevent recurrence by means of adjuvant chemotherapy and careful follow-up studies.

  • In gastric cancer, the only potentially curative treatment is surgery that attempts to achieve curative (R0) resection. However, despite the use of curative resection, a recurrence develops in a high percentage of patients, especially in cases of serosa and/or lymph node involvement. As a strategy to improve the survival of the patients with resectable advanced gastric cancer, neoadjuvant chemotherapy has been evaluated in several phase II trials and a few phase III trials. The results of these trials have confirmed the feasibility and safety of this approach with no apparent increase in surgical complications. Recently, the findings of a large phase III randomized trial (MAGIC trial) have indicated that compared to the use of surgery alone, perioperative chemotherapy, using both a neoadjuvant and adjuvant strategy, decreased the number of T and N stage cancers and improved survival. The results of another recent phase III trial (FNLCC 94012/FFCD 9703) also showed that compared to the use of surgery alone, perioperative chemotherapy improved the R0 resection rate and survival. In both trials, the improved outcomes may be attributed to the use of neoadjuvant chemotherapy because of poor compliance with adjuvant chemotherapy. These results cannot be directly translated to clinical practice in Korea due to differences in surgical techniques and outcomes. However, the findings of a few small phase II and III trials performed in patients with locally advanced gastric cancer in Korea have also suggested that neoadjuvant chemotherapy would result in the improvement of the R0 resection rate and down-staging of the disease. More effective chemotherapy regimens are needed in future large randomized trials to determine the subset of patients that will benefit from neoadjuvant chemotherapy and to determine the extent of benefit.

  • Background : To find out effectiveness of multimodality treatments based on induction chemotherapy(CTx) in patients with clinical stage IIIA NSCLC Methods : From 1997 to 2002, 74 patients with clinical stage IIIA NSCLC underwent induction CTx at the hospital of Chungnam National University. Induction CTx included above two cycles of cisplatin-based regimens(ectoposide, gemcitabine, vinorelbine, or taxol) followed by tumor evaluation. In 30 complete resection group, additional 4500-5000cGy radiotherapy(RTx) was delivered in 15 patients with pathologic nodal metastasis. 29 out of 44 patients who were unresectable disease, refusal of operation, and incomplete resection were followed by 60-70Gy RTx in local treatment. Additional 1-3 cycle CTx were done in case of induction CTx responders in both local treatment groups. Results : Induction CTx response rate were 44.6%(complete remission 1.4% & partial response 43.2%) and there was no difference of response rate by regimens(p=0.506). After induction chemotherapy, only 33 out of resectable 55 ones(including initial resectable 37 patients) were performed by surgical treatment because of 13 refusal of surgery by themselves and 9 poor predicted reserve lung function. There were 30(40.5%) patients with complete resection, 2(2.6%) persons with incomplete resection, and 1(1.3%) person with open & closure. Response rate in 27 ones with chest RTx out of non-operation group was 4.8% CR and 11.9% PR. In complete resection group, relapse free interval was 13.6 months and 2 year recur rate was 52%. In non-complete resection(incomplete resection or non-operation) group, disease progression free interval was 11.2 months and 2 year disease progression rate was 66.7%. Median survival time of induction CTx 74 patients with IIIA NSCLC was 25.1months. When compared complete resection group with non-complete resection group, the median survival time was 31.7 and 23.4months(p=0.024) and the 2-year overall survival rate was 80% and 41%. In the complete resection group, adjuvant postoperative RTx subgroup significantly improved the 2-year local control rate(0% vs. 40%, p= 0.007) but did not significantly improve overall survival(32.2months vs. 34.9months, p=0.48). Conculusion : Induction CTx is a possible method in the multimodality treatments, especially followed by complete resection, but overall survival by any local treatment(surgical resection or RTx) was low. Additional studies should be needed to analysis data for appropriate patient selection, new chemotherapy regimens and the time when should RTx be initiated.

  • Background : The safety and efficacy of trabeculectomy with Mitomycin C (MMC) for surgical treatment in aphakic and pseudophaic eyes were retrospectively evaluated. Materials and Methods : The authors reviewed 51 eyes of 45 patients who had been followed up for at least 6 months after trabeculectomy using MMC for aphakic and pseudophakic eyes. The success rate and complications were analyzed. The success criteria included intraocular pressures of 21 mmHg or less with or without glaucoma medications and no loss of light perception. Surgical failure was defined as a postoperative loss of light perception in patients with preoperative vision better than light perception, additional glaucoma surgery, or phthisis bulbi in patients with preoperative vision of no light perception. Results : The average follow up period was 27.7 months and the intraocular pressure was controlled under 21 mmHg in 36 eyes of 51 (70.6%) after the procedure with or without medication for glaucoma. Using the Kaplan-Meier survival analysis, the cumulative success rate at the 3-, 6-, 12-, 24- and 36-month intervals were 98.0%, 94.1%, 91.9%, 83.4% and 75.5%, respectively. The complications observed were hyphema (4 eyes), serous choroidal detachment (4 eyes), hypotony (3 eyes), and endophthalmitis (1 eye). Conclusion : Trabeculectomy using Mitomycin C for the treatment of aphakic and pseudophaic eyes was safe and effective.

  • Purpose: The aim of this study was to compare quality of life of long-term survivors after a subtotal or a total gastrectomy for gastric cancer. Materials and Methods: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire and QLQ-STO22 questionnaire were used to assess quality of life of 166 patients on their 5th annual follow-ups after gastrectomy for gastric cancer. One hundred twenty-six patients underwent a subtotal gastrectomy and 40 patients a total gastrectomy. Results: The subtotal gastrectomy group revealed a trend to have better quality of life in functional scales (physical, role, emotional, cognitive and social), fatigue, pain, dyspnea, diarrhea and financial difficulties. The total gastrectomy group showed a trend to have better quality of life in the global health status and quality of life, nausea and vomiting, insomnia, appetite loss and constipation. In all scales of the EORTC QLQ-STO22, the subtotal gastrectomy group had a trend to have better quality of life. However these did not reach the statistical significance. Conclusion: Surgeons may not limit the extent of resection concerning long-lasting poor quality of life. Oncologically sound resection is recommended.

  • Myasthenia gravis is relatively rare disease which is related autoimmune response. There are various methods of management for myasthenia gravis, but nowaday radical thymectomy is the treatment of choice in the aspect of bringing out complete remission and clinical improvement. Sixteen patients of myasthenia gratis underwent radical thymectomy during last eight years, and its result was analysed. Complete rem ssion was achieved in five patients (31 %) and pharmacological or symptomatic improvement in seven patients (44%), thus giving a total remission in 12 patients (75%). Postoperative result was not correlated with age, sex, degree of preoperative symptom, surgical approach, pathologic diagnosis.
