title: The use of a detachable mini-loop for the treatment of esophageal varices.
abstract: BACKGROUND
  Endoscopic variceal ligation is facilitated by multiband ligating devices, but these have limitations including a fixed number of bands, occasional failure to firmly ligate a variceal column, and relatively high cost. We report the use of a mini-loop for treatment of esophageal varices.
  
  
  METHODS
  A detachable nylon ring (mini-loop), maximum diameter 11 mm, passed through the accessory channel of a standard endoscope is opened at the rim of a transparent ligation chamber attached to the instrument. By suction, a varix is brought into the chamber, the mini-loop is maneuvered over the varix, closed, and detached.
  
  
  RESULTS
  Five ligation sessions (four to seven loops per session) were performed in four patients with upper gastrointestinal bleeding. There were variceal stigmata of bleeding, but no active hemorrhage. Application of all mini-loops was successful and did not induce uncontrolled bleeding. Endoscopy at 1 week disclosed superficial ulcers at ligation sites. Post procedure epigastric pain occurred in one patient.
  
  
  CONCLUSIONS
  Detachable mini-loop ligation of esophageal varices is simple and safe, and a comparison study with a multi-band ligator device is warranted.
