Successful Simultaneous Treatment of Benign Stricture and Colonic Neoplasm Arising from Colonic Interposition after Esophagectomy: A Case Report / 대한소화기학회지

Colonic interposition is the main procedure used in esophageal reconstruction. We report a rare case of simultaneous treatment of an anastomotic site stricture and a neoplasm in the interpositioned colon. A 69-year-old female visited our outpatient clinic with symptoms of progressive dysphagia for 1 year. At the age of 30 years, the patient underwent esophagectomy with retrosternal colonic interposition because of severe esophageal burns after chemical ingestion. Upper gastrointestinal endoscopy revealed stricture at the anastomosis site and a 10-mm flat elevated high-grade dysplasia in the interpositioned colon. First, through-the-scope balloon dilatation was performed for strictures. However, stenosis was observed during the second upper gastrointestinal endoscopy session.Therefore, a second session of through-the-scope balloon dilatation was performed, and simultaneously, endoscopic submucosal dissection was also successfully performed. After 2 months of follow-up, stenosis persisted; consequently, balloon dilatation was performed. No recurrence of neoplasm was confirmed endoscopically. Through-the-scope balloon dilatation of the stricture site and simultaneous endoscopic submucosal dissection of the neoplasm in the interpositioned colon were successfully performed.

Novel Technique to Rescue a Folded Aortic Endograft during Endovascular Aneurysm Repair

Endovascular aneurysm repair has been established as a safe and effective treatment modality for infrarenal abdominal aortic aneurysms. Although rare, major technical failure can lead to intraoperative surgical conversion, which is associated with high mortality and morbidity rates. We herein report a case in which one of the endograft limbs was folded over on itself within the aneurysmal sac during endovascular aneurysm repair. The aneurysm was successfully repaired by a total endovascular approach using endoscopic grasping forceps without open surgical repair.

Two-stage Surgery for an Aortoesophageal Fistula Caused by Tuberculous Esophagitis

An aortoesophageal fistula (AEF) is an extremely rare, potentially fatal condition, and aortic surgery is usually performed together with extracorporeal circulation. However, this surgical method has a high rate of surgical complications and mortality. This report describes an AEF caused by tuberculous esophagitis that was treated successfully using a two-stage operation. A 52-yr-old man was admitted to the hospital with severe hematemesis and syncope. Based on the computed tomography and diagnostic endoscopic findings, he was diagnosed with an AEF and initially underwent thoracic endovascular aortic repair. Esophageal reconstruction was performed after controlling the mediastinal inflammation. The patient suffered postoperative anastomotic leakage, which was treated by an endoscopic procedure, and the patient was discharged without any further problems. The patient received 9 months of anti-tuberculosis treatment after he was diagnosed with histologically confirmed tuberculous esophagitis; subsequently, he was followed as an outpatient and has had no recurrence of the tuberculosis or any further issues.

Comparative Analysis of Surgical Thrombectomy with Revision and Percutaneous Thrombectomy with Angioplasty for Treating Obstruction of a Dialysis Graft / 대한흉부외과학회지

BACKGROUND: Salvaging prosthetic arteriovenous grafts can be performed using surgical or endovascular techniques. We conducted a retrospective analysis to compare the efficacy of these two methods for restoring dialysis graft function. MATERIAL AND METHOD: We studied 41 patients who had received surgical thrombectomy with revision (Group A) or percutaneous thrombectomy with angioplasty (Group B) from January 2006 to December 2007. We compared them according to the patient characteristics and the location of stenotic lesions, and we analyzed the postintervention primary patency rates. RESULT: 21 patients underwent surgery and 20 patients underwent percutaneous balloon angioplasty. There were no significant differences of the patients' characteristics between the two groups. Venous anastomotic stenosis was the most common cause of graft thrombosis in both groups. In Group A, 90.5% of the grafts remained functional at 6 months and 38.1% remained functional at 12 months. In Group B, 55.0% of the grafts were functional at 6 months and 20.0% of the grafts were functional at 12 months. The post-intervention primary patency rate was significantly better in Group A (p=0.034). CONCLUSION: Surgical treatment resulted in significantly longer post-intervention primary patency in this study, and this supports its use as the primary method of management for most patients in whom dialysis graft obstruction develops.

Nodular Fasciitis on an Anterior Chest Wall / 대한흉부외과학회지

A 40-year-old woman was admitted to the hospital due to a palpable tumor on an anterior chest wall. The tumor was diagnosed with a nodular fasciitis. It is a rare benign soft-tissue tumor which has a characteristic referred to as proliferation of fibroblast, and a surgical removal is the best effective treatment. Therefore, we report this case with documents and considerations after the surgical removal.
