Perforation of the peptic ulcer is one of the common and lethal complications of the peptic ulcer. Unless the prompt diagnosis is made and early active surgical management is done the mortality is very high, it is the commonest cause of death resulting from surgical abdominal emergency next to intestinal obstruction. The patients who are brought to the hospital at a late stage, have the major concurrent illness and preoperative shock, do not improve with conservative treatment. In spite of the better understanding of the disease, effective resuscitation and prompt surgery under modern anesthesia techniques, there is high morbidity and mortality. Hence, an attempt has been made to analyze the various factors, which are affecting the etiology, incidence, postoperative morbidity/mortality of patients with peptic ulcer perforations. Our study comprises of 104 cases of perforated peptic ulcer that were admitted in the Department of General Surgery, National Institute of Medical Sciences and Research, Jaipur from January 2017-June 2018. This study on the cases of perforated peptic ulcer was carried out to study the various risk factors that can and do affect the operative outcome in perforated peptic ulcer. In our study, we found out that the highest incidence of perforated peptic ulcer was in the 4th decade. Males are the most affected gender(70.19%). Ingestion of NSAIDs increases the risk of peptic ulcer perforation. Duodenal perforations were commoner then gastric in present series. The classical symptoms of peptic ulcer like pain, periodicity, vomiting, and hematemesis were observed in present work. Most common postoperative complications were pulmonary complications(16.35%).All over mortality rate was 12.5%
