A total of 55 patients underwent surgical managements for postintubation tracheal stenosis from July 1975 through March 1997. All but 8 had received ventilatory assistance. The patients had S cuff lesions, 17 stoma lesions, 7 at both levels, 5 at subglottic lesions. Thirty two patients underwent the sleeve tracheal resection and end-to-end anastomosis. Five patients performed a wedge resection and end-to-end anastomosis. Twenty two patients received the Montgomery T-tube for relief of airway obstruction. Simple excision of granulation tissue was done in 7 patients. Rethi procedures(anterior division of cricoid cartilage, partial wedge resection of lower thyroid cartilage and T-tube molding) were performed in 2 subglottic stenosis patients. And the other subglottic patient was received permanent tracheal fenestration at 1975. The tracheoesophageal fistula patient was done sleeve tracheal resection and end-to-end anastomosis with interrupted double layer closure of esophageal fistula site. Cervical approach was used in 49 cases, cervicomediastinal in 13 cases and median stemotomy In 6 cases. Techniques for obtaining tension-free anastomosis included a cervical neck flexion(15-30$^{\circ}$) in all sleeve resection patients and laryngeal release in one. The length of resection was 1.5 to 5.0 on A total of 41 patients(74.5%) had good(24 patients) or satisfactory(17 patients) results. But in ten cases, the restenosis of anastomosis site which is the most common complication was developed Two of them underwent a second reconstruction and 8 patients required T-tube insertion for airway maintenance. Three patients(5.4%) died. The causes of death were tracheo-innominate artery fistula(2) and sudden obstruction of airway(1).

Despite improvement in respiratory care, including use of low pressure and high volume cuffed tubes, tracheal stenosis remains a serious complication after a long-term tracheal intubation and tracheostomy. In such patients, tracheal resection and primary anastomosis is still considered ideal therapeutic modality. Between 1989 and 1997, we performed tracheal resections with end-to-end anastomosis on 14 patients with no operative mortality and some morbidity. Tracheal stenosis was caused by tracheostomy in nine patients, by endotracheal intubation in three patients and by thyroid carcinoma in two patients. The length of stenosis was various from 2cm to 4.5cm. All patient underwent segmental tracheal resection and primary anastomosis(14 patients) and additional procedures were cricoid cartilage reconstruction(2 patients), suprahyoid laryngeal release(3patients), carinal release technique(2 patients) and arytenoidectomy(2 patients). We have nine complications: granulona at anastomosis site in four patients, vocal cord palsy in two patients and restenosis, pneumonia, skin necrosis in each of those patients. The granuloma was removed by bronchoscopic forceps(4 patients). Vocal cord palsy was treated by arytenoidectorny(2 patients), restenosis by T-tube insertion, pneumonia by antibiotics and skin necrosis was treated by skin graft. We reviews our expenence of clinical features of tracheal stenosis and surgical treatment by tracheal one-to-end anastomosis with additional procedures to avoid postoperative complications for sucessful results.

Background： Tracheal resection and end-to-end anastomosis are the preferred treatment for tracheal tumor or tracheal stenosis. Absorbable suture material has been commonly used in case of tracheal anastomosis. But anastomosis technique is controversial. This experimental study compared between interrupted suture and continuous suture using Polydioxanone (PDS) absorbable suture material after tracheal resection and end-to-end anastomosis in rabbits. Methods : Twenty-four rabbits were used, divided into two groups of 12 animals each. The trachea was resected and then anastomosed with continuous 6-0 polydioxanone (PDS) (group 1), and intermittent 6-0 polydioxanone (PDS) (group 2). The animals were followed up for 6 months. Stenosis of the trachea was assessed at the time of death. Results : In two groups, anteroposterior diameter, transverse diameter, cross sectional area, and perimeter were greater in group 2 than in group 1 but, not significantly different. In addition, histologic findings were not different in two groups. Conclusions : This study suggest that stenosis after tracheal resection and end-to-end anastomosis using absorbable polydioxanone (PDS) suture material be not significantly different in both groups.

Tracheostomy and endotracheal intubation are often performed in patients with acute and chronic respiratory failure. Recently, the incidence of iatrogenic tracheal stenosis has increased. Tracheal resection and end-to-end anastomosis would be one of the most physiologic treatment options for severe tracheal stenosis. Also, this treatment can be applied to the management of trachea invaded by thyroid cancer and tracheal neoplasm. The authors aimed to analyze the outcomes of end-to-end anastomosis of trachea following segmental resection in tracheal stenosis and tracheal invasion of cancer that we have recently experienced. Materials and methods Authors retrospectively studied 19 cases treated by tracheal resection with end-to-end anastomosis between Feburuary 1996 and January 2003. 12 patients had tracheal stenosis, 6 patients had tracheal invasion by thryroid cancer and 1 patient had tracheal cancer. We analyzed the direct causes of tracheal stenosis, preoperative vocal cord function, operation technique, early and delayed postoperative complications, and the outcome of end-to-end anastomois. Result Decannulation without significant aspiration was achieved in 16 cases($89.5\%$). A 27 year-old man could not be decannulated because of restenosis. A 62 year-old woman could not be decannulated because of bilateral vocal cord palsy. Conclusion End-to-end anastomosis is a safe and effective surgical method for tracheal stenosis. Case selection for end-to-end anastomosis and preservation of recurrent laryngeal nerve during operation is very important.

Aim: To evaluate the outcome of stapled versus sutured colo-rectal anastomosis after low anterior resection of mid-rectal carcinoma. Patients and Methods: A prospective study of fifty patients who underwent colo-rectal anastomosis following low anterior resection (LAR) of T2 mid-rectal cancers at the Egyptian National Cancer Institute during the time period from June 2010 to June 2013 was conducted. Classification was into two groups; a stapled anastomosis group I (25 patients) and a hand-sewn anastomosis group II (25 patients). All operations are evaluated regarding intra-operative complications such as anastomotic line bleeding, visceral injuries or major blood loss. The anastomotic time and operative time are documented for each operation. All patients are evaluated post-operatively for anastomotic leakage (AL), wound infection and ileus. Results: The distance of the tumor from the anal verge was $9.6{\pm}2.0cm$ in group I and $9.9{pm}2.4cm$ in group II. The mean operative time was $191.5{\pm}16.2min$ in the stapled group and $208{\pm}18.6min$ in the sutured group (p=0.002). The mean anastomotic times were $9.0{\pm}1.9min$ and $19.7{pm}12.2min$ (p=0.001). Anastomotic leakage developed in three (12.0%) patients in the stapled group and in four (16.0%) patients in the sutured group (p=1.000). Post-operative ileus was observed in 3 patients in group I and one patient in group II. Wound infection developed in three (12.0%) patients in the stapled group and four (16.0%) patients in the sutured group (p=1.000). Conclusion: Colo-rectal anastomosis after low anterior resection for mid rectal carcinoma can be conducted safely either by stapling or hand-sewn techniques; however the stapling technique showed shorter anastomotic and operative times with no significant advantages regarding intra- or post-operative complications or hospital stay.

The extent of resection and release of the trachea is important for successful anastomosis. Bilateral bronchial dissection is one of the release techniques for resection of the lower trachea. We present the experience of cervical video-assisted mediastinoscopic bilateral bronchial release for long segmental resection and anastomosis of the lower trachea.

For most surgeons, stomach and colon are the first choice for reconstruction of the esophagus, as well as for bypass. When the esophagogastric or esophagocolonic anastomosis is made in the neck, cervical anastomosis site leakage is the main complication. In our most recent four patients who underwent a transhiatal & posterior mediastinal esophagogastric or esophagocolonic anastomoses following esophageal resection, we performed the cervical anastomoses with a circular EEA stapler. No leaks have developed at the anastomosis site. In these four patients the cancer was tiny and was located on the upper or middle third of the thoracic esophagus. A total esophagectomy was performed by blunt resection without thoracotomy. Surgical staplers have been used previously for esophagogastric anastomosis through a right thoracotomy with a very low rate of leakage. When the esophagogastric or esophagocolonic anastomosis is performed in the neck, the prevalence of leakage does not increase the postoperative mortality, but it can increase significantly the duration of hospitalization and morbidity. The use of the circular stapler allowed us to perform four consecutive cervical esophagogastric & esophagocolonic anastomoses without any leakage and to shorten the operating time.

Laryngotracheal stenosis is one of the most troublesome diseases in the Em field. Subglottic stenosis can be treated by a cricoid augmentation with rib cartilage. In case of tracheal stenosis, the treatment of choice is by tracheal end-to-end anastomosis after resection of the stenotic site. However, in case of subglottic stenosis combined with tracheal stenosis, it is hard to manage. Even though several methods(such as thyrotracheal anastomosis) have been tried, they have some limitations too much excision of normal trachea and too much pulling up of the trachea after resection of the stenotic lesion. The authors have managed two cases of laryngotracheal stenosis as an anterior and posterior subglottic augmentation with an autologous cartilage graft and laryngotracheal anastomosis. The first few weeks after the operation, we could do a decannulation successfully, but in one case the patient developed restenosis. Even though one case was unsuccessful, the authors believe that this method could be used in the treatment of laryngotracheal stenosis.

Between 1975 and 1992, forty five patients with trachea stenosis received tracheoplasty for relief of obstruction. The causes of airway problem are brain contusion[19 cases, 40%], cerebrovascular disease[3 cases, 7%], drug intoxication[8 cases, 18%], psychotic problem[2 cases, 4%], trachea tumor[3 cases, 7%], adult respiratory distress syndrome[9 cases, 20%] and direct trauma[1 case, 2%]. Direct causes of trachea stenosis were complications of tracheostomy[36 cases, 80%], complications of nasotracheal intubation[5 cases, 11%], tumor[3 cases, 6%] and trauma[1 case, 2%]. Thirty one patients underwent the sleeve resection and end-to-end anastomosis. Five patients performed a wedge resection and end-to-end anastomosis. Forteen patients received the Montgomery T-tube for relief of airway obstruction. Four patients have done simple excision of granulation tissue. Two, subglottic stenosis patients were received Rethi procedure[anterior division of cricoid cartilage, wedge partial resection of lower thyroid cartilage and Montgomery T-tube molding] and the other subglottic stenosis patient underwent permanent trachea fenestration. Including cervical flexion in all patients postoperatively, additional surgical techniques for obtain tension-free anastomosis were hyoid bone release technique in two cases, and hilar mobilization, division of inferior pulmonary ligament and mobilization of pulmonary vessel at the pericardium were performed in one case. Cervical approach was used in 39 cases, cervicomediastinal in 12 cases and transthoracic in one case. Complications of tracheoplasty were formation of granulation tissue at the anastomosis site[3 cases], restenosis[9 cases], trachea-innominate artery fistula[2 cases], wound infection[2 cases], separation of anastomosis[2 cases], air leakage[3 cases], injury to a recurrent laryngeal nerve[temporary 8 cases, permanent 2 cases] and hypoxemia[1 case]. Surgical mortality for resection with primary reconstruction was 6.7%, with one death due to postoperative respiratory failure and two deaths due to tracheo-innominate artery fistula.

기관 협착의 치료에는 주기적인 확장, 기관내시경을 통한 협착 조직의 제거, T-tube 삽입 등의 보존적 방법과 수술적 방법이 있다. 그러나, 최근 수술을 통한 기관 절제 및 단단문합술이 기능적으로나 해부학적으로 정상적인 상기도 확보에 효과적인 것으로 보고되고 있어 그 결과를 알아보고자 한다. 대상 및 방법: 1990년 3월부터 2002년 7월까지 울산대학교 의과대학 서울아산병원에서 기관 절제 및 단단문합술을 시행한 환자 41예를 대상으로 의무기록을 참조하여 후향적으로 분석하였다. 결과： 원인 질환으로는 postintubation stenosis 26예,기관에 발생된 원발성 기관종양이 10예(양성 3예, 악성 7예), 기관내 결핵 1예, 외상 2예, 그리고 갑상선암이 2예였다. 기관 절제 및 단단문합술을 시행한 환자 41예 중 29예는 기관 절제 및 단단 문합술을 시행하였고, 12예는 갑상연골 또는 윤상연골 절제가 동반된 후두 기관 문합술을 시행하였다. 후두 기관 문합술을 시행한 11예 중 4예에서 후두분리술 (supralaryngeal release)을 시행하였다. 절제된 기관의 길이는 평균 $3.6{\pm}1.0$cm였다. 기관 절제 및 단단 문합술을 시행한 41예의 환자 중 수술 후 상태가 양호한 환자는 30명(73.2%)이었고, 수술 직후 일부문합 부위에 육아종 증식 또는 감염이 있었으나 보존적 치료 후 호전된 환자는 8명(19.5%)으로 전체환자 중 92.7%에서 수술 후 양호한 기도의 확보가 가능하였다. 합병증으로는 육아종 증식을 보여 보존적 치료를 시행한 환자가 7예, 창상감염 2예, 문합부 dehiscence 2예, 운동 시만 호흡곤란을 보이면서 특별한 치료없이 지내는 재협착이 1예, 수술 후 반복적인 기도 흡인으로 재기관절개술을 시행한 환자가 1예 있었다. 기관 절제 및 단단문합술과 직접 관련된 30일 내의 조기사망은 없었고, 원내사망이 3예 있었다 결론: 기관 절제 및 단단문합술은 높은 성공률과 낮은 유병률 및 사망률을 보여 병변의 길이가 적절한 경우, 기관 수술의 표준이 될 수 있을 것으로 생각한다 그러나, 수술부위 육아조직 증식이 가장 심각한 합병증으로 이를 방지하기 위한 지속적인 연구와 노력이 필요할 것으로 생각한다.
