Abstract
Acute abdomen is a very common presentation in emergency department and a widespread health problem. A large portion of those patients necessitate rapid surgical interference. All preoperative assessment of clinical history and examination, laboratory investigations, radiological investigations ranging from X ray, ultrasound, and CT examinations should be done. All of these measures, which may not be available or may be contraindicated for the patient, even with best hands, can’t diagnose large portion of these cases either for necessity of surgery or for specific pathology. from this point importance of laparoscopy arises. As a diagnostic tool it was proven to be significantly more diagnostic than all measures ; catching surgically positive cases, and avoiding unnecessary negative laparotomies. As a therapeutic tool ; it proved reasonable efficacy in treatment of acute appendicitis, acute cholecystitis, perforated peptic ulcer and gynecological causes of acute abdomen. As for outcome, it was very satisfactory regarding mortality, complications and length of hospital stay and far more satisfactory than open surgery. This prospective study conducted on 114 patients in Mansoura university hospital and Mansoura emergency hospital from May 2011 to August 2014. Most of our patients were female 60 (58%) and males represented the minority 44cases (42%).Mean age was 28.5±11.3 ranging from8 – 67; about 83% of them aged from 10 to 40 years. We excluded Patients with contraindication to laparoscopy (uncontrolled hypercapnea, coagulopathies), patients with severe abdominal distention and history of repeated abdominal surgery. We accomplished complete laparoscopic diagnosis in 88.5% of cases, and avoided negative laparotomy in 12.5% of cases. We converted about 23% of laparoscopically diagnosed cases to open surgery for therapeutic purposes with significant reduction in complications in laparoscopic cases and mean hospital stay 3.6 days in laparoscopic cases vs 5.3 days in open cases Conclusion: Laparoscopy was an excellent diagnostic tool. It was a very good therapeutic tool in acute appendicitis, acute cholecystitis, perforated peptic ulcer and gynecological causes of acute abdomen. It was also safe and satisfactory, also it saved more hospital beds
