OBJECTIVES

To evaluate the frequency and clinical importance of portal hypertensive gastropathy (PHG) and gastric varices (GV) before endoscopic sclerotherapy (EST) and after esophageal variceal obliteration.

METHODS

Patients with portal hypertension (PHT) with variceal bleed were prospectively evaluated for PHG and GV before EST with intravariceal injection of absolute alcohol and after esophageal variceal obliteration. Gastric varices and PHG were characterized and graded according to previously established criteria. Patients were followed up for 12-48 (mean 37) months after variceal obliteration.

RESULTS

Of 70 patients with PHT 26 had PHG before (severe in two) [18/37 in cirrhosis, 6/20 in non-cirrhotic portal fibrosis (NCPF), and 2/13 in extrahepatic portal vein obstruction (EHPVO)] and 50 had PHG after variceal obliteration (severe in 22) (27/37 in cirrhosis, p = 0.03 before versus after esophageal variceal obliteration; 16/20 in NCPF, p < 0.01; and 7/13 in EHPVO, p = ns). Type I GV (continuation of esophageal varix into the stomach) was found in 25/70 before and 5/70 after esophageal variceal obliteration (p < 0.001); in contrast, other types of GV were seen in 14/70 before and 29/70 after (p < 0.01). Overt bleeding from GV and PHG during follow-up after variceal obliteration occurred in 6 and 4 patients, respectively.

CONCLUSIONS

Esophageal variceal obliteration by EST increases the frequency of PHG and GV (except type I GV which get obliterated); both PHG and GV have potential to cause rebleeding.
