Background and objective: Villous adenoma is the most common tumour of the
papilla of Vater, and transition from adenoma to carcinoma is now generally
accepted as proven. It is thus essential for an adenoma to be removed, Met
hods of removal have ranged from endoscopic sling papillectomy to partial d
uodenopacreatectomy. It was the aim of this study to determine whether recu
rrence can be prevented by local resection.
Patients and methods: 58 patients with a benign tumour of the papilla (26 m
en, 32 women; average age 59 [range from 18 to 81] years) were included. De
pending on preoperative histology, intraoperative frozen-section diagnosis
and macroscopic histopathology, some form of surgical intervention was unde
rtaken, most often resection of the ampulla. The clinical course and findin
gs at postoperative follow-up were recorded and the absence of recurrence c
hecked by endoscopy.
Results: Ampullectomy was performed in 49 of the 58 patients, papillectomy
in three. Although frozen-section examination had failed to reveal any mali
gnancy, resection of the head of the pancreas with preservation of the pylo
rus was done in six patients, carcinoma having been suspected macroscopical
ly. There were no operative deaths. An adenoma had been found in 44 patient
s, one quarter of them showing severe dysplasia: follow-up examinations aft
er a mean interval of 45 months (range of 6-180 months) failed to find any
recurrence.
Conclusion: Ampullectomy provides an adequate surgical treatment of benign
adenoma of the ampulla of Vater. Accurate surgical technique and pre-, intr
a- and final histopathological diagnosis by an experienced pathologist are
decisive factors in determining the ultimate outcome. If the histological f
indings as to benignity are unclear, resection of the head of the pancreas
with preservation of the pylorus by an experienced surgeon is indicated.
