Q.2.3: What is the best non-operative management of patients with uncomplicated acute appendicitis? |
3. Timing of appendectomy and in-hospital delay | Q.3.1: Does in-hospital delay increase the rate of complications or perforation for adult patients with uncomplicated acute appendicitis? Q.3.2: Does in-hospital delay increase the rate of complications or perforation for pediatric patients with uncomplicated acute appendicitis? |
4. Surgical treatment | Q.4.1: Does laparoscopic appendectomy confer superior outcomes compared with open appendectomy for adult patients with acute appendicitis? Q.4.2: Does laparoscopic appendectomy confer superior outcomes compared with open appendectomy for pediatric patients with acute appendicitis? Q.4.3: Does laparoscopic single-incision surgery confer any advantage over the three-trocar technique in performing laparoscopic appendectomy for adult patients with acute appendicitis? Q.4.4: Does laparoscopic single-incision surgery confer any advantage over the three-trocar technique in performing laparoscopic appendectomy for pediatric patients with acute appendicitis? Q.4.5: Is outpatient laparoscopic appendectomy safe and feasible for patients with uncomplicated acute appendicitis? Q.4.6: Is laparoscopic appendectomy indicated over open appendectomy in specific patient groups? Q.4.7: Does aspiration alone confer clinical advantages over lavage and aspiration for patients with complicated acute appendicitis? Q.4.8: Does the type of mesoappendix dissection technique (endoclip, endoloop, electrocoagulation, Harmonic Scalpel, or LigaSure) produce different clinical outcomes for patients with acute appendicitis undergoing appendectomy? Q.4.9: Does the type of stump closure technique (stapler or endoloop, ligation or invagination of the stump) produce different clinical outcomes for patients with acute appendicitis undergoing appendectomy? Q.4.10: Is the use of abdominal drains recommended after appendectomy for complicated acute appendicitis in adult patients? Q.4.11: Is the use of abdominal drains recommended after appendectomy for complicated acute appendicitis in pediatric patients? Q.4.12: What are the best methods to reduce the risk of SSI in open appendectomies with contaminated/dirty wounds? |
5. Intra-operative grading of acute appendicitis | Q.5.1: What is the value of scoring systems for intra-operative grading of acute appendicitis? Q.5.2: Should the macroscopically normal appendix be removed during laparoscopy for acute right iliac fossa pain when no other explanatory pathology is found? |
6. Management of perforated appendicitis with phlegmon or abscess | Q.6.1: Is early appendectomy an appropriate treatment compared with delayed appendectomy for patients with perforated acute appendicitis with phlegmon or abscess? Q.6.2: Is interval appendectomy always indicated for patients with acute appendicitis following successful NOM? |
7. Perioperative antibiotic therapy | Q.7.1: Is preoperative antibiotic therapy recommended for patients with acute appendicitis?
