Effective relief of dysphagia in unresectable esophageal cancer patients not only prolong survival but also is prerequisite for other treatment modalities.We tried surgical resection in 4 patients who had unresectable esophageal cancer,managed initially with esophageal prosthesis then followed by chemotherapy with good response. Curative resection was possible in 2 patients and palliative resection in one and exploration only in one case.Curatively resected patients are alive without recurrence for 57 months,8 months,each.Other non-curatively resected patients died after 10 months,7 months. Above results suggest that initial esophageal prosthesis to relieve dysphagia followed by chemotherapy in unresectable esophageal cancer may provide another chances for curative resection that promise better survival and need more clinical experience and trial.

Background : Electrolarynx, Esophageal voice, and Silicone voice prosthesis with tracheoesophageal(T-E) fistula have been used as vocal rehabilitating methods for the post-laryngectomized patients. Prosthetic rehabilitation of voice after total laryngectomy has gained wide acceptance and has become a common practice in many clinics since the pioneering works of Singer and Blom In 1979. Since the introduction of tracheo-esophageal puncture and application of Blom Singer$\circledR$ voice prosthesis in 1980, several reliable voice prostheses have been developed and are successfully being used. Objectives : Even though quality of voice produced by Silicone voice prosthesis with T-E fistula is superior to other modalities, it still has some disadvantages. We devised a new cannulatyped silicone voice prosthesis. Methods : 1) Devising a new prototype of cannula-typed silicone voice prosthesis. 2) Application of the prototype using canine animal model(laryngectormized dog) and fitting trial on human patient whose previously inserted Silicone voice prosthesis is not functioning due to presumed fungal infection. Discussion : Final form of prototype was made after several times of major and minor modifications. Insertion of the newly developed Cannula-typed Silicone voice prosthesis on canine animal model and human trial were done without any difficulty. There were no serious leakage of saliva or food during swallowing. Conclusion : The newly developed Cannula-typed Silicone voice prosthesis(So-Mang$\circledR$) and the modified replacement method will further improve the results of post-laryngectomized prosthetic voice rehabilitation. Long-term animal study and human trial are planned in the near future.

Cancers of the cervical esophagus occur uncommonly, but treatment is remaining a challenging problem and surgery demands special knowledge of abdominal, thoracic, and neck surgery. The primary risk factor is chronic heartburn, leading to a sequence of esophagitis, Barrett's esophagus, reflux esophagitis and etc. Among the various treatment modalities, Surgery is still a mainstay of treatment. The main aim of surgery is not only oncologically adequate resection but also preservation or restoration of physiologic functions, such as deglutition and phonation. Surgical treatment of cervical esophageal cancer is influenced by special problems arising from tumor factors, patient factors and surgeon factors. Complete clearance of loco-regional disease and prevention of postoperative complications are of particular importance for the improvement of long-term survival in patients with these cancers. So the cervical and thoracic extension of these tumors usually required an extensive lymphadenectomy with primary resection. Radical resection of the primary site almostly include sacrifice of the larynx, but the voice could be rehabilitated with various methods, such as tracheoesophageal prosthesis or tracheoesophageal shunts, etc. Restoration of the esophageal conduit can be performed using gastric or colon interposition, radial forearm free flap or jejunum free flap, etc. Recently, the advances of radiation therapy and chemotherapy will enable less extended resections with greater rates of laryngeal preservation. At initial presentation, up to 50％ to 70％ of patients will have advanced locoregional or distant disease with virtually no chance for cure. Patients with advanced but potentially resectable esophageal cancer are generally treated by surgery with some form of neoadjuvant chemotherapy, radiotherapy, or both, with 5-year survivals in the 20％ to 30％ range. So the significant adverse factors affecting survival should be taken into account to select the candidates for surgery.

Background and Objectives : Esophageal voice, Silicone voice Prosthesis with tracheo-esophageal (T-E) puncture have been used as vocal rehabilitation methods for postlaryngectomy. However, long-term follow-up in the voice rehabilitation in the total laryngectomees has not been reported. The purpose of this study is to analyze practice of postlaryngectomy voice rehabilitation and to find the effective voice rehabilitation. Materials and Methods : From Jan 1992 until June 2002, 75 patients underwent a total laryngectomy at Yongdong Severance Hospital. We retrospectively studied voice rehabilitation methods commonly used, acquisition levels of esophageal speech, patients satisfaction scale (5 rating scale) according to the methods in 33 of them (40 died, 2 unavailable) by using charts review, telephone interview. Results : T-E speech is most commonly used by 14 patients (42.4%) : A tracheo-esophageal procedure (primary or secondary puncture) by 21 : and 8 patients removed Provox. 1 patient had no voice rehabilitation. 7 patients (21.2%) have used esophageal speech : 4 patients of them have used it after removing Provox. Electrolarynx has been used with other voice rehabilitation methods : 4 patients have only used this method and 3 patients with T-E speech, 1 patient with esophageal speech. However, 6 patients (18%) remained without a substitute voice rehabilitation. In the satisfaction with speech and management of voice rehabilitation methods, patients using esophageal speech were most satisfied (4.1), patients with T-E speech were unsatisfied (2.3). Regarding with the acquisition level of esophageal speech in 33 patients, 22 patients (66.6%) failed without functional speech. Conclusion : To increase patients satisfaction and to achieve successful voice rehabilitation after total laryngectomy, preoperative counseling, pretesting, appropriate patient selection of each method and team decision-making and postoperative voice therapy must be considered.

Total laryngectomy is the most useful procedure tor advanced laryngopharyngeal cancer, but it remains the major problem such as loss of voice. Voice restoration is essential for every patients who undergo a total laryngectomy. Ideal voice rehabilitation methods can resolve three factors. First, every laryngectomee can produce voice sufficient for communication, second every patient should be allowed to use both hands freely during phonation, and last, the voice restoration methods should be easy and safe without complication during and after treatment. Among various voice rehabilitation procedures during or after total laryngectomy, it can be divided electronic and pneumatic methods. In pneumatic methods, there are also divided both pulmonary air and non-pulmonary air methods. The non-pulmonary air methods include esophageal speech, buccal speech, and pharyngeal speech. Pulmonary air methods are divided into surgical and non-surgical such as pneumatic speech aid. In the surgical methods, there are neoglottic operation, tracheopharyngeal shunt, and tracheopharyngeal shunt operations. Recently, tracheoesophageal shunt with or without prosthesis are being recognized the most effective method. Blom-Singer low pressure prosthesis, Panje button, and Provox are well known types of prosthesis in the tracheoesophageal shunt operation. Amatsu method is a kind of famous tracheoesophageal shunt method without using prosthesis. Authors tried to review the published articles for evaluation of effectiveness and problems of tracheoesophageal shunt operation with or without prosthesis. In conclusion, indwelling type of prosthesis and pharyngeal myotomy and plexus neurectomy are recommended for higher success rate during tracheoesophageal puncture procedure. More over, Amatsu method is also one of the recommended voice rehabilitation procedure during total laryngectomy. In this situation, pharyngeal myotomy and plexus neurectomy may be helpful for better fluent communication.

배경: 식도질환의 수술 후 식도재건술은 아직도 식도수술에 관여하는 외과의사에게 해결해야 될 부분이 많이 있다. 1996년 1월부터 1999년 12월가지 흉부식도암환자 27명에서 흉부식도절제술 후 15예의 식도-위 문합술과 12예의 유리총장 이식술을 시행하였다. 저자들은 식도암 수술 후 문합부 누출, 문합부위의 협착, 역류성식도염, 수술시간, 호흡기 합병증 등을 양 군을 나누어 비교하였다. 대상 및 방법: 고식적 우회술 또는 식도인공삽입술, 인두식도와 식도 위 결합부위의 암은 본 연구에서 제외하였다. 우측 개흉술로 식도를 절제하였고, 자동봉합기를 사용하여 식도-위 문합을 시행하였다. 유리공장이식술의 경우 근위부의 식도는 6예에서 자동봉합기를 사용하였으며, 6예의 근위부와 12예의 원위부는 수기통합하였다. 모든 식도 재건술은 후종격동을 경유하였다. 결과: 3예의 수술사망을 포함하여 3예의 문합부 누출, 2예의 이식공장괴사 등 중한 합병증과 11예의 역류성 식도염, 5예의 문합부 협착이 발생되었다. 식도-위 문합술의 평균 수술시간은 300$\pm$160분, 유리공장이식술은 550$\pm$280분이었다. 결론: 역류성 식도염은 식도-위 문합군에서 더 많았고, 수술시간은 유리공장이식군에서 더 길었다(p<0.05). 적절한 환자의 선택과 장시간의 수술에 따르는 술 후 합병증을 줄일 수 있다면, 식도재건수술후의 역류식도염을 감소시키는 수술로 유리공장이식술이 우수하다고 판단된다.

섭식 연하장애는 수술이나 치료로 인한 기질적 원인, 뇌혈관장애나 뇌성마비, 근육이나 신경장애 등으로 인한 기능적 원인, 그리고 거식증이나 폭식증과 같은 심리적 원인에 의해 발생할 수 있다. 치과의원급에서는 주로 음식물의 인식장애 단계부터 인두로의 전달장애 단계까지의 환자에게 적극적으로 도움을 줄 수 있으며, 그 방법으로는 치의학적 전문지식을 바탕으로 환자의 섭식, 저작과정을 주의 깊게 관찰하여 문제점을 파악하여 각 단계에 적절한 기초 훈련과 섭식 훈련을 실시하는 것이며, 또한 필요시 혀 접촉 보조장치와 같은 장치를 제작하여 환자에게 장착시키고 섭식, 연하 훈련을 시행하여 환자의 연하능력을 개선시켜줄 수 있다. 하지만 무엇보다 가장 중요한 것은 환자가 식전과 식후에 엄격한 구강관리를 시행할 수 있도록 잘 지도하고, 치과의 정기적 방문과 전문적 관리를 통해 구강내 저작기관의 해부학적, 기능적 문제점을 해결해 주도록 하며, 이 때 마다 심리적으로도 환자가 섭식, 연하에 문제가 없도록 세심하게 설명하고 상담해 주는 것으로, 이는 모두 치과의사의 책무라고 할 수 있다.

Tracheoesophageal puncture (TEP) and voice prosthesis insertion following laryngectomy may fail to form an adequate seal. When spontaneous closure of the fistula tract does not occur after conservative measures, surgical closure is required. The purpose of this study was to summarize the available evidence on surgical methods for TEP site closure. A comprehensive search across PubMed, Web of Science, SCOPUS, and Cochrane was performed to identify studies describing surgical techniques, outcomes, and complications for TEP closure. We evaluated the rate of unsuccessful TEP closure after surgical management. A meta-analysis with a random-effect method was performed. Thirty-four studies reporting on 144 patients satisfied inclusion criteria. The overall incidence of an unsuccessful TEP surgical closure was 6% (95% confidence interval [CI] 1-13%). Subgroup analysis showed an unsuccessful TEP closure rate for silicone button of 8% (95% CI < 1-43%), 7% (95% CI < 1-34%) for dermal graft interposition, < 1% (95% CI < 1-37%) for radial forearm free flap, < 1% (95% CI < 1-52%) for ligation of the fistula, 17% (95% CI < 1-64%) for interposition of a deltopectoral flap, 9% (95% CI < 1-28%) for primary closure, and 2% (95% CI < 1-20%) for interposition of a sternocleidomastoid muscle flap. Critical assessment of the reconstructive modality should take into consideration previous history of surgery or radiotherapy. Nonirradiated fields and small defects may benefit from fistula excision and tracheal and esophageal multilayer closure. In cases of previous radiotherapy, local flaps or free tissue transfer yield high successful TEP closure rates. Depending on the defect size, sternocleidomastoid muscle flap or fasciocutaneous free flaps are optimal alternatives.

Reconstruction of the pharynx and cervical esophagus presents a tremendous surgical challenge to the Head and Neck Surgeon. Because life expectancy of patients with advanced carcinoma of the hypopharynx, and cervical esophagus is limited, treatment must be aimed at palliation. A variety of techiques have been proposed over the years with none proving entirely satisfactory. These techiques include prosthesis; skin graft; cervical flaps; tubed cutaneous and myocutaneous chest flaps; visceral reconstruction with stomach, colon. and jejunum; and jejunal free autografts. Many factors dictate the best method of reconstruction in any given clinical situation. The goal of the surgery is a one-stage reconstruction of swallowing function with minimal morbidity to allow as short a hospital stay as posible. Nine patients underwent the free jejunal autograft reconstruction of the pharyngoesophagus after the ablative surgery for the advanced hypopharyngeal cancer. Postoperative complications included one perioperative death, two abdominal wound dehiscences, two neck hematomas, one carotid rupture, one funtional dysphagia, one late strictures. There were no graft failure, no immediate stenosis and no fistula. An oral diet was started between days 8 and 16, with an average of 9 days and median of 8 days. Patients left the hospital between days 9 and days 38, with an average of 23.4 days and median of 23 days. This method of reconstruction is advocated as reliable palliative procedure with short-term follow-up. In conclusion, we at Korea Cancer Center Hospital are of the opinion that the free jejunal autograft offers an excellent, safe and relative easy method of the pharyngeal and cervical esophageal reconstruction with significant advantages over other techiques.
