Abstract
AIM: To investigate the efficacy and safety of combined use of endoscopic high-frequency coagulation and laser for the treatment of restenosis after stent placement in patients with cervical esophageal carcinoma.
METHODS: A total of 15 cervical esophageal carcinoma patients with restenosis after stent placement were included in the study. Endoscopic high-frequency coagulation was used for protruding lesions, while combined use of high-frequency coagulation and laser was used for tubular infiltrating lesions or other types of lesions. The diameter of the esophagus and the extent of stenosis were evaluated before and after treatment.
RESULTS: All the 15 patients received the surgery successfully and could take food without difficulty 12 hours later. No complications such as esophagus hemorrhage or perforation occurred.
Preoperative luminal diameter at the stenosis ranged from 3.8 to 4.2 mm, while improved luminal diameter (12.8 to 13.2 mm) was achieved postoperatively. One month later, 11 atients had a complete response, three patients had partial response, and one patients had minor response. The overall response rate was 100%.
CONCLUSION: Combined use of endoscopic high-frequency coagulation and laser is safe and effective for the treatment of restenosis after stent placement in patients with cervical esophageal carcinoma, and can improve patients' quality of life.
