Perforation peritonitis is one of the most common surgical conditions encountered in surgical practice and is a common cause of morbidity and mortality and warrants early surgical intervention. In the study all patients were devided into 2 groups ie. Group Apatients came with in 48 hours from the starting of the symptoms to our institute. Group B­patients came from 48 hours to 144 hours from the starting of the symptoms to our institute. In our study we do a prospective evaluation and comparision of the post operative complications in both the groups viz A&B in the following headings viz. Local complications: Surgical site infection, Burst abdomen, Anastomotic leak, Post operative intestinal obstructionIncisional hernia. Systemic complications: Septicemia Respiratory complications(significant pleural effusion, pneumonia, lung abscess) MODS, Renal failure, DVT, Hospital stay, Deaths. Significant increase in complications rate were observed in late presenting group viz Group B as compared to early presenting group viz Group A.complications rate were increased in Group B by following viz Surgical site infection (by 12.5%),Burst abdomen(by 8.45%), Anastomotic leak(by 7.60%) ,Post operative intestinal obstruction (by 4.90%), Incisional hernia (by 11.39%). Septicemia (by 13.48%), Respiratory complications(by 5.88%), MODS(4.41%), Renal failure(6.74%), DVT (by1.47%) . Average hospital stay was increased by 5 days in Group B patients. Death percentage was also increased by 12.62% in delayed presenting group. Poverty, lack of knowledge and education,lack of sufficient medical facility, lack of registered medical practitioners, practicising quacks and tendency of disease ignorance and self medication make the situation worst which leads to delayed presentation of acute and life threatening illness to specialized medical care centres in India. Abbreviations: MODSMulti organ dysfunction syndrome. DVT­ Deep vein thrombosis.
