Between Dec. 1958 and Oct. 1989, we had been experienced 14 cases of the esophageal corrosion carcinoma among 562 cases of corrosive esophageal stricture, which incidence was revealed 5.6 % of total esophageal carcinoma cases and 2.5 9o of total benign esophageal stricture cases. The age distribution was from 15 to 64 years, and the mean age was 45.6 years. Ten of the patients were women. The caustic agents were lye in 12 patients and hydrochloric acid in 2 patients. The latent time from injury to the development of carcinoma was from 12 years to 45 years, and the mean latent time was 29 years. In majority of cases, the developing site of carcinoma was just or just above the benign stricture portion of the esophagus. Corrective surgery were made in seven cases; three cases were made esophagectomy and esophagogastrostomy, and the other four cases were made esophagectomy and colon interposition. Palliative surgery including feeding gastrostomy were made in seven cases. All cases had a longstanding history of difficult oral swallowing especially at the site of stricture. We think chronic food irritations of stricture portion of the esophagus induced the development of corrosion carcinoma. In conclusion, we had to suspect possibility of carcinoma in patient with long standing history of benign esophageal stricture. So we recommended preoperative esophagoscopic biopsy in such cases.

During a ten-year period from August, 1978 to September, 1989 45 patients with benign esophageal stricture were surgically evaluated. The results are as follows; l. Out of 45 patients, there were 26 males and 19 females ranging from 2 to 70 years of age with a mean of 31.9 years. 2. The most common cause of benign esophageal stricture was corrosive burn due to caustic agents[40 cases, 88.9 %]. Corrosive agents were 15 cases of lye, 22 cases of acid and 3 cases of other agents. Other causes were two cases of esophageal web and each one case of previous surgical result, inflammation and idiopathic mediastinal fibrosis respectively. 3. The most frequent stricture site was whole esophagus as 21 cases[46.7 %] and the next was lower a third thoracic esophagus[10 cases, 25.0%]. 4. In 33 of total 45 cases, colon interposition with right colon was performed without resection of the strictured esophagus except one case which was complicated esophageal cancer. Other procedures were 4 cases esophagogastrostomy with segmental resection, 2 cases of plastic repair and so on. 5. Major postoperative complications which were needed for secondary operation were 5 cases[11.1 %]. [2 cases of stenosis, ileus and ulcer bleeding respectively] Overall mortality rate was 4.4 %.

Background: For the purpose of reducing operating time and rate of anastomotic leakage, we have performed esophagovisceral anastomosis with an EEA stapler using the largest size possible. If any difficulty in the approach of the EEA stapler was encountered one-layer interrupted hand-sewn anastomosis. Because the rate of postoperative benign anastomotic stricture was higher than expected, a retrospective study was done on all patients who underwent esophageal reconstruction. Material and Method: Over a period of 3 years from January 1996 to December 1998, we performed esophageal reconstructions on 30 patients. Patients were divided into two groups ; EEA stapler group(Group Ⅰ) comprised of 21 patients and hand-sewn group(Group Ⅱ) comprised of 9 patients.Result:The hospital mortality was 6.67 %(2/30) and the anastomotic leakage rate was 3.33 %(1/30). Among the discharged patients, the rate of recurrent anastomotic tumor was 3.57 %(1/28) and the rate of benign anastomotic stricture stricture rate was 35 %(7/20) in Group Ⅰ and 12.5 %(1/8) in Group Ⅱ, which was not significant. Conclusion: Although nontumor benign stricture was significantly higher in Group Ⅱ than in Group Ⅰ(p=0.0492), the incidence of anastomotic complications did not differ between the two groups. The one-layer interrupted hand-sewn esophagovisceral anastomosis by maintaining a wide lumen and close approximation of mucosa to mucosal layers with evenly spaced sutures could be one of the preferred surgical method to reduce benign anastomotic strictures.

Benign biliary stricture (BBS) is a complication of chronic pancreatitis (CP). Despite endoscopic biliary stenting, some patients do not respond to treatment, and they experience recurrent cholangitis. We report two cases of CP with refractory BBS treated using endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) fistula creation. A 50-year-old woman and a 60-year-old man both presented with obstructive jaundice secondary to BBS due to alcoholic CP. They underwent repeated placement of a fully covered self-expandable metal stent for biliary strictures. However, the strictures persisted, causing repeated episodes of cholangitis. Therefore, an EUS-CDS was performed. The stents were eventually removed and the patients became stent-free. These fistulas have remained patent without cholangitis for more than 2.5 years. Fistula creation using EUS-CDS is an effective treatment option for BBS.

Background/Aims: Hepaticojejunostomy anastomotic stricture (HJAS) is a feared adverse event associated with hepatopancreatobiliary surgery. Although balloon dilation for benign HJAS during endoscopic retrograde cholangiopancreatography with balloon-assisted enteroscopy has been reported to be useful, the treatment strategy remains controversial. Therefore, we evaluated the outcomes and risk factors of recurrent stenosis after balloon dilation alone for benign HJAS. Methods: We retrospectively analyzed consecutive patients who underwent balloon-assisted enteroscopy-endoscopic retrograde cholangiopancreatography for benign HJAS at our institution between July 2014 and December 2020. Results: Forty-six patients were included, 16 of whom had recurrent HJAS after balloon dilation. The patency rates at 1 and 2 years after balloon dilation were 76.8% and 64.2%, respectively. Presence of a residual balloon notch during balloon dilation was an independent predictor of recurrence (hazard ratio, 2.80; 95% confidence interval, 1.01-7.78; p=0.048), whereas HJAS within postoperative 1 year tended to be associated with recurrence (hazard ratio, 2.43; 95% confidence interval, 0.85-6.89; p=0.096). The patency rates in patients without a residual balloon notch were 82.1% and 73.1% after 1 and 2 years, respectively. Conclusions: Balloon dilation alone may be a viable option for patients with benign HJAS without residual balloon notches on fluoroscopy.

Between September 1988 and December 1993, 32 cases of benign esophageal stricture, of which 12 males and 20 females, were managed in Seoul National University Hospital hospital. Their age ranged from 2 to 61 years, and the mean age was 33.9 years. The ingestion of caustic agent was the most common cause, and the caustic material was acid in 16 patients [58% and alkali in 11patients [39% . Nearly all of the patients complained of dysphagia, and some of chest pain, epigastric pain, weight loss, vomiting, general malaise, and dyspnea. The most frequent site of stricture was found in the upper thoracic esophagus with 34% incidence followed by the lower thoracic esophagus[28% , whole esophagus[19% , and the mid esophagus[16% . The operations performed were 17[53% ECG[esophagocologastrostomy , 5[16% PCG[pharyngocologastrostomy , 5[16% EG[esophagogastrostomy , 2 EJG [esophagojejunogastrostormy by free jejunal graft , and 1 case each of EJ [esophagojejunostomy , esophageal end to end anastomosis, jejunostomy only, and gastrostomy only. In 23 patients [72% , diseased esophaguses were resected, using transhiatal total esophagectomy in 15 [47% and transthoracic partial esophagectomy in 8 [25% . Of those 23 patients, 3 patients [9.4% were diagnosed as esophageal carsinoma on microscopic examination. The postoperative most common complications were unilateral vocal cord palsy in 6 patients [19% , followed by cervical anastomosis leakage in 4 patients [12.5% , wound infection in 2 patients [6% , and pneumothorax in 2 patients [6% . Late death occurred 8 months after the operation in one patient, which was associated with infection due to anastomotic leakage. Our experience shows that the rate of mortality and the morbidity were low in patients receiving surgical management for esophageal stricture and that the cancer transformation rate was high. We recommend esophageal reconstruction surgery with esophagectomy [transhiatal or transthoracic for the esophageal stricture because it can avoid a chance of prevent cancer transformation.

목적: 위악성 종양으로 위전절제술 및 식도공장문합술을 시행 받은 환자에서 발생할 수 있는 문합부 양성협착의 빈도와, 위험인자 및 이에 대한 치료에 대해 알아보고자 하였다. 대상 및 방법: 1998년 3월부터 2001년 2월까지 근치적 위전절제술 후 자동문합기를 사용하여 루앙와이 식도공장 문합술을 시행 받은 658명에서 추적관찰 기간 중 내시경 검사를 시행한 436명을 대상으로 후향적으로 분석하였다. 협착은 직경 9mm 내시경의 통과여부로 정의하였다. 결과: 남자는 292명, 여자는 144명이었고, 평균(mean) 나이는 53.7세$(23{\sim}81)$세였다. 436명 중 33명에서 문합부 협착이 진단되었으며 이 중 재발에 의해 협착이 발생한 9명을 제외한 24명을 대상으로 분석하였다. 성별, 나이, 자동문합기의 직경, 항암화학요법, 방사선치료, 역류성 식도염 여부, 당뇨 및 고혈압 등의 위험인자들과 양성협착 사이에 통계학적으로 의미 있는 결과를 보이지 않았다. 문합부 양성협착이 발견된 모든 환자에서 풍선확장술을 시행하였으며, 시행 후 모든 환자에서 증상의 호전을 보였다. 결론: 위험인자들과 문합부 양성협착의 발생빈도 사이의 관계를 조사한 결과 통계학적으로 의미 있는 인자는 없었으나 문합부 혈류와 관계된 인자들에 대해 추가적인 조사가 필요할 것으로 생각된다. 증상의 호전을 위하여 내시경 풍선 확장 시술을 시행하고 1회의 시술로 증상의 호전을 보이지 않는 경우가 있어 지속적인 내시경 추적검사가 요구된다.

양성 식도협착에 대한 분절절제술 및 단단문합술은 식도-장관 문합술에 비해 수술침습도가 적고 식도 고유기능을 보존할 수 있으므로, 짧은 분절의 식도협착에서 수술방법으로 고려해야 하지만 임상 보고나 분석에 대한 연구는 매우 적은 실정이다. 본원 흉부외과에서는 수술 후 문합부 협착이 있는 13개월 여아와 부식성 식도협착이 있는 27세 여자를 대상으로 단단문합술을 적용한 임상경험을 하였기에 보고하는 바이다. 생후 2일째 식도무형성증-식도기관누공에 대한 수술 후 발생한 문합부 협착인 경우는 결과가 좋았으나, 경부 식도의 고도 부식성협착에서는 단단문합술 후 다시 협착이 재발하여 인후-대장-위 문합술을 시행하게 되었다. 양성 식도협착에 대한 단단문합술은 협착의 범위와 원인에 따라 적응증을 선택하여 사용된다면 좋은 치료 방법이라고 생각하나 더 많은 연구가 필요하리라 생각한다.

배경:식도-위 문합술시 EEA stapler가 도입됨으로써 문합부 누출의 발생을 줄여 술후 사망률의 감소에 기여하게 되었으나 문합부 협착의 발생이 수기봉합에 비해 높은 단점이 있다. EEA stapler를 이용한 식도-위 문합술시 문합부 협착의 발생을 줄이고, 또 문합부 협착의 치료에 도움이 되고자 연구를 시행하였다. 대상 및 방법: 1986년 1월부터 1996년 12월 까지 약 11년간 고신대학교 의학부 흉부외과에서 EEA stapler를 이용하여 식도-위 문합술을 시행한 195명의 환자 중 술후 조기에 사망한 10명를 제외한 185명를 대상으로 문합부 협착에 대한 분석을 시행하였다. 결과: 문합부 협착은 185명의 환자 중 39명에서 발생하여 21%의 발생율을 나타내었고 발생시기는 술후 1개월에서 3개월 사이에 25례(64.1%)로 가장 많이 발생하였다. 문합부 협착이 발생한 환자군과 발생하지 않은 환자군 사이에 연령의 차이는 없었으며 문합의 위치에 따른 문합부 협착의 발생율은 흉곽 입구부에서 문합한 환자군에서 기관분기 하부에서 문합한 환자군에 비해 조금 높았으나 통계학적인 유의성은 없었다. 문합시 사용된 cartridge의 크기와 문합부 협착의 발생율의 비교에서 작은 cartridge를 사용한 예에서 문합부 협착의 발생율이 높게 나타났다(p=0.04). 결론: 이상의 결과로 EEA stapler를 이용하여 식도-위 문합술시 가능한 큰 cartridge를 사용함으로써 문합부 협착의 발생을 줄일수 있을 것으로 사료되며 문합부 협착이 발생한 경우에는 1∼2회의 풍선확장술의 시행이 안전하고 확실한 치료방법으로 확인되었다.

Pancreaticobiliary tract strictures are frequent Indications for endoscopic retrograde cholangiopancreatography(ERCP). We have investigated the brushing cytology in order to determine its efficacy for diagnosis of pancreaticobiliary malisnancies. Brushing cytology during ERCP was evaluated in 56 patients with biliary tract stricture presenting to the Catholic Hospital of Taegu-Hyosung from April 1997 to August 1999. A comparison was made between the cytologic and histologic diagnoses on 32 cases from 30 patients. A diagnosis of malignancy was establishied in 78.1%, benign in 15.6%, and inadequate in 6.3% of the cases. Statistical data on cytologic diagnoses in strictures of the bile duct were as follows; specificity and sensitivity of blushing procedure was 100% & 83.3%, respectively: sensitivity of interpretation was 89.3%: with no false positive cases and 3 false negative cases: predictive value for malignancy was 100% & 100%, respectively: predictive value for benign was 28.6% & 40%,, respectively: overall diagnostic efficiency was 84.4%. It is concluded that brush cytology is a diagnostically reliable, highly specific technique for malignant lesions encounted at ERCP, although a negative result does not rule out the diagnosis of malignancy.
