Methods Fifty-five cases of duodenal ulcer performed LGCFS from 1983 to 1991 at the Third Affiliated Hospital of SUN Yat-sen University were followed up by means of letters, telephone and outpatient reexamine. The curative effects were classified by the Visick scale. Results Forty-seven cases were followed up.The Visick classification results were: (1) Twenty-five (78.1%), 2(6.3%), 3(9.4%) and 2(6.3%) cases being classified as Visick I,II,III,IV respectively among 32 cases without any complication.(2) Five (33.3%), 2(13.3%), 2(13.3%) and 6(40.0%) cases being classified as Visick I,II,III,IV respectively among 15 cases with complications. (3) Thirty (63.8%), 4 (8.5%), 5 (10.6% ) and 8 (17.0% ) cases were classified as Visick I,II,III,IV respectively among 47 cases. Conclusion LGCFS is simple and has few complications.The long term curative effect is good for duodenal ulcer without any complication.But it is bad for duodenal ulcer with complications,especially for duodenal ulcer with pyloric obstruction because of the high recurrent rate of pyloristenosis after LGCFS plus pylorodiosis.
