[Evaluation of conditioning factors of morbimortality in duodenopacreatectomy in periampullary neoplasms].

Objective: The purpose of this study is to define the factors that condition complications and mortality in a group of 119 patients with periampullary neoplasms operated on at a general hospital.

Materials And Method: Between October 2002 and December 2006, 119 patients who were diagnosed with periampullary neoplasms and underwent a pancreatoduodenectomy at Rebagliati Hospital were evaluated.

Results: Age and sex were not conditioning factors of complications.

[Morbidity and mortality rates in relation to the "surgeon factor" after duodenopancreatectomy].

Objectives: The present study was designed to determine whether the surgeon factor has an independent effect on morbidity and mortality rates after duodenopancreatectomy.

Material And Method: Between October 2002 and December 2006, we performed a study of 119 patients who underwent duodenopancreatectomy. The surgeons were divided into 3 groups according to the number of interventions they performed each year: a low volume group (three Whipple procedures per year), a medium volume group (four to 10 Whipple procedures per year) and a high volume group (> 10 Whipple procedures per year).
