Closed pyloroduodenal digital dilatation as a complementary drainage procedure to truncal vagotomy.

Out of a total of 300 consecutive cases of duodenal ulcer undergoing surgery, 51 patients were treated by truncal vagotomy and a closed pyloroduodenal digital dilatation. A peroperative assessment of the pyloroduodenal canal was carried out, and in patients with a mobile, supple duodenum showing minimal scarring a standard drainage procedure was not considered necessary. In these patients it was possible to perform a closed pyloroduodenal digital dilatation using the two thumbs to achieve an effective dilatation of 20-30 mm. Post-operative clinical evaluation (Modified Visick grading) and "special" barium meal revealed 86% of patients in Grade I and II at the end of two years (maximum follow-up 3.5 yrs.), with no evidence of lasting gastric stasis. The method is easy, safe and simple. It maintains the anatomical and physiological integrity of the pyloroduodenal ring thereby obviating the hazards of an "incontinent" stomach. Its main limitation appears to be its restricted selectivity and in the present series it could be carried out in about 17% of cases.
