AIM: Endoscopic methods are currently the most widely used techniques for the treatment of bleeding oesophageal varices (BOV). However, a number of complications may limit their usefulness. We conducted a prospective, randomized comparison of variceal ligation versus sclerotherapy in cirrhotics after the control of variceal haemorrhage to study the relative short-term risks of these two procedures with respect to oesophageal motility and gastro-oesophageal reflux.
METHODS: Seventy-three patients with established cirrhosis and an episode of variceal bleeding controlled by one session of endoscopic therapy were randomized to treatment with sclerotherapy or ligation until variceal eradication. In 60 of these patients, oesophageal manometry and 24-h intra-oesophageal pH monitoring were performed at inclusion and 1 month after variceal eradication.
RESULTS: After variceal eradication with sclerotherapy, peristaltic wave amplitude decreased from 76.2 +/- 14.7 mmHg to 61.6 +/- 17.7 mmHg (P = 0.0001), simultaneous contractions increased from 0% to 37.9% (P = 0.0008), and the percentage of time with pH < 4 increased from 1.60 +/- 0.25 to 4.91 +/- 1.16% in channel 1 (P = 0.0002) and from 1.82 +/- 0.27 to 5.69 +/- 1.37% in channel 2 (P = 0.0006). In contrast, the above parameters were not disturbed with ligation.
CONCLUSION: Our data define the advantages of ligation over sclerotherapy with respect to post-treatment oesophageal dysmotility and associated gastro-oesophageal reflux.
