Endoscopic variceal ligation treating esophageal varices
The Journal of abdominal surgery, 2020Co-Authors: Zheng ZeAbstract:Objective To study the clinical value of endoscopic variceal ligation in the treatment of esophageal varices.Methods Nylon Loop Ligator and pneumd active Ligator were applied to cure the esophageal varices.Results 12 cases were cured and the total effective rate was 97.5% .Conclusion The endoscopic variceal ligation is a safe,feasible and effective therapy for esophageal varices.

Endoscopic variceal ligation in the management of gastroesophageal varices in postoperative biliary atresia
Journal of Pediatric Surgery, 1998Co-Authors: Takashi Sasaki, Toshimichi Hasegawa, Kiyokazu Nakajima, Hirofumi Tanano, Masafumi Wasa, Yuichi Fukui, Akira OkadaAbstract:Abstract Background/Purpose: Gastroesophageal variceal bleeding is a serious and difficult problem in the long-term management of biliary atresia (BA). Recently, endoscopic approaches have been attempted to manage this problem. The authors have attempted endoscopic variceal ligation (EVL), a less invasive procedure than endoscopic sclerotherapy. Methods: In the past 5 years, 66 EVL procedures using standard flexible endoscope with a diameter of 9 mm (type p-30, XQ200, or XQ240; Olympus, Tokyo, Japan) were performed in 30 separate sessions on 11 postoperative BA patients. The mean age of the children was 7.8 (range, 3 to 15) years. The EVL device was a small elastic O-ring or a Loop Ligator. Results: EVL was performed for emergency hemostasis in two patients and prophylaxis for impending rupture in nine with large, blue varices, or with red spots on the variceal surface. During the initial procedure, all varices were ligated successfully, and reduction in size was noted. Of eight patients who were examined 7 to 14 days after treatment, seven (87.5%) had improved. Eight of 11 patients (72.7%) were finally cured or at least had improved after one to seven sessions of EVL. However, three patients did not show improvement after four to seven sessions because of the reappearance of the varices, development of distal lesions such as gastric varices, and acute gastric mucosal lesions. A technical complication encountered was a slippage of the O-ring in one patient. A technical difficulty was seen in ligating the giant gastric varix in one patient. There was no deterioration of liver function induced by EVL in this entire series. Conclusions: EVL is an effective and feasible treatment of gastroesophageal varices in postoperative BA patients. However, reappearance or reactivation of the varices or emergence of the more distal lesions is likely to occur even after repeated EVL.
