Background/Aims: The aim of this study was to evaluatethe outcome of endoscopic dilation for benign anastomoticstricture after radical gastrectomy in gastric cancer patients. Methods: Gastric cancer patients who underwent endoscopicballoon dilation for benign anastomosis stricture afterradical gastrectomy during a 6-year period were reviewedretrospectively. Results: Twenty-one patients developedbenign strictures at the site of anastomosis. The majority ofstrictures occurred within 1 year after surgery (95.2%). Themedian duration to stenosis after surgery was 1.70 months(range, 0.17 to 23.97 months). The success rate of the firstendoscopic dilation was 61.9%. Between the restenosisgroup (n=8) and the no restenosis group (n=13), there wereno significant differences in the body mass index (22.82 kg/m2 vs 22.46 kg/m2), interval to symptom onset (73.9 daysvs 109.3 days), interval to treatment (84.6 days vs 115.6days), maximal balloon diameter (14.12 mm vs 15.62 mm),number of balloon dilation sessions (1.75 vs 1.31), locationof gastric cancer or type of surgery. One patient required surgerybecause of stricture refractory to repeated dilation. Conclusions:Endoscopic dilation is a highly effective treatmentfor benign anastomotic strictures after radical gastrectomyfor gastric cancer and should be considered a primary interventionprior to proceeding with surgical revision.
