ABSTRACT

Introduction: Mortality from perforated peptic ulcer still remains high as a result of more perforations in the elderly who are generally more ill. We conducted this retrospective study to determine the adverse operative risk factors for perforated peptic ulcers.

Materials and Methods: Two hundred and six consecutive patients operated for perforated peptic ulcers from 1 January 1993 to 31 December 1997 were reviewed.

Results: Majority (n = 194) of the patients had perforations at the pyloroduodenal region and the remaining 10 patients had perforated benign gastric ulcers. The median age at surgery was 58 years (range 18 to 91 years). Forty-four patients (21.4%) were more than 70 years old. The 30-day operative mortality rate was 10.7% (n = 22). Advanced age (>70 years), female gender, concurrent major medical illness, perforation developed while hospitalised for other medical illnesses, prolonged perforation (>24 hours) and preoperative hypotension (systolic blood pressure <90mmHg) were indicators for operative mortality by univariate analysis. By logistic regression analysis, only concurrent major medical illness, prolonged perforation and preoperative hypotension were independent adverse risk factors. The operative mortality rate for patients with 0, 1, 2 and 3 independent adverse risk factors were 0%, 11%, 30% and 88%, respectively.

Conclusions: As concurrent medical illness is a non-modifiable factor and preoperative hypotension is usually resulting from treatment delay and inadequate resuscitation, emphasis should place on shortening the time to surgery as well as prompt resuscitation.


Although there has been a significant decline in elective surgery for peptic ulcer disease with the introduction of H-2 blocker, the incidence of peptic ulcer perforation has remained relatively unchanged over the years. The mortality rate from perforated peptic ulcer remains high as more perforations occur in the elderly who are generally more ill.
