ObjectiveTo summarize the experience of colon interposition for esophageal replacement. MethodThe clinical data of 108 consecutive patients underwent colon interposition for esophageal replacement in our hospital between January 2005 and March 2013 were reviewed for benign and malignant lesions. Their ages ranged from 2 to 71 years (mean age at 34.3 years). There were 81 males and 27 females. ResultThere was no surgical death. Esophago-colic anastomotic insufficiency occurred in 7 patients. One case of graft necrosis was observed. Injury of recurrent laryngeal nerve occurred in 8 patients, incomplete intestinal obstruction in 2 patients, and wound infection of the abdominal wall in 1 patient, and deep venous thrombosis in 1 patient. In-hospital mortality was 15.7% (17/108). The postoperative follow-up was made for 12 months in 97 patients (91.5%) and all of them were alive. The patients' body weight and appetite improved. ConclusionColon interposition is a valuable alternative with a good long-term function.
The esophageal disease is a major clinical disease. The esophageal stent has extensive clinical applications in the treatment of esophageal diseases. However, the clinical application of esophageal stent is limited, because there are lots of complications after implantation of esophageal stent. Biodegradable esophageal stent has two advantages: biodegradability and good histocompatibility. It is expected to solve a variety of complications of esophageal stent and provide a new choice for the treatment of esophageal diseases. Standardized esophageal stents are not fully applicable to all patients. The application of 3D printing technology in the manufacture of biodegradable esophageal stent can realize the individualized treatment of esophageal stent. And meanwhile, the 3D printing technology can reduce the manufacturing cost of the stent. This review aimed to summarize and discuss the application of esophageal stent, the current research status and prospect of biodegradable esophageal stent and the prospect of 3D printing technology in degradable esophageal stent, hoping to provide evidence and perspectives for the research of biodegradable esophageal stent.
Esophageal diseases include esophageal malignant diseases and benign diseases, with a high incidence in our country. Along with the development of the endoscopic technique, many of them which required medical treatment or surgery in the past can now be cured by endoscopic surgery. This article is an overview of long-term follow-up of endoscopic surgery for the common esophageal disease, such as early squamous cell carcinoma, esophageal stricture, achalasia and submucosal tumor of the esophagus.
