Over a 6-year period at Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria, 22 patients presented with prepyloric or duodenal ulcer perforations- a relatively low yearly rate of about four. Of the 15 patients evaluated, approximately three-quarters were working class young men and eight 53%) had no ulcer history. The high morbidity, and 20% mortality rate, observed were attributable to late presentation and the presence of advanced bacterial peritonitis in 67% of the patients at admission. Imprecise clinical features in those with small perforations led to misdiagnosis in a third of cases. Treatment of perforations in the majority (93%) of patients was by simple closure or truncal vagotomy and pyloroplasty.<\/jats:p>\n                  <jats:p>An increase in patients' awareness of the potentials of optimal operative management should encourage earlier presentation.<\/jats:p>","DOI":"10.1177\/004947559802800309","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T18:52:33Z","timestamp":1484333553000},"page":"152-155","source":"Crossref","is-referenced-by-count":2,"title":["Clinical Pattern of Perforated Prepyloric and Duodenal Ulcer at Ile-Ife, Nigeria"],"prefix":"10.1177","volume":"28","author":[{"given":"O O","family":"Lawal","sequence":"first","affiliation":[{"name":"Department of Surgery, College of Health Sciences, Obafemi Awolowo University, Ile-Ife, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S F","family":"Oluwole","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Health Sciences, Obafemi Awolowo University, Ile-Ife, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O A","family":"Fadiran","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Health Sciences, Obafemi Awolowo University, Ile-Ife, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Campbell","sequence":"additional","affiliation":[{"name":"Department of Surgery, College of Health Sciences, Obafemi Awolowo University, Ile-Ife, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1998,7,1]]},"reference":[{"key":"bibr1-004947559802800309","unstructured":"Adeloye A.
