“…In order to improve the results, attempts were ruade to delineate the surgeon failures and, according to many reports, subsequent improvement of technique diminished the number of failures [8][9][10][11][12][13][14][15][16][17][18][19][20]. The supposed completeness of the vagotomy, however, was not always a guarantee against recurrence [21][22][23][24][25][26], so that it should perhaps be postulated that failures inherent in the method do occur after HSV [27][28][29][30]. Probably all series of HSV's with apparently unavoidable recurrences contain a mixture of method failures and surgeon failures, and these cannot be distinguished with certainty at present.…”
