Appendicitis in pregnancy: an ongoing diagnostic dilemma.Brown JJ, Wilson C, Coleman S, Joypaul BV Department of Surgery, South Tyneside NHS Foundation Trust Hospital, Harton Lane, South Shields, UK. j.j.s.brown@ncl.ac.uk INTRODUCTION: Appendicitis in pregnancy (AIP) is the most common nonobstetric cause of an acute abdomen requiring surgical intervention. Diagnostic difficulties arising from gestational symptoms compound the risk of foetal loss after negative appendicectomy and exponentially increase the risk to mother and foetus with delay in genuine cases. In this article, we investigate the symptoms and signs of AIP and attempt to identify consistent clinical features and review the role of imaging in diagnosis. METHOD: MEDLINE and PubMed were searched for case-control studies recording preoperative symptoms/signs suggestive of AIP, as well as appendiceal pathology. Combined likelihood and odds ratios (OR) were created for clinical features across homogenous papers. Papers examining the use of laparoscopy, ultrasound (US), computerized tomography (CT) and magnetic resonance imaging (MRI) were assessed qualitatively. RESULTS: Seven papers met the inclusion criteria for the analysis of consistent clinical features (450 patients). The only symptoms or signs significantly associated with a diagnosis of appendicitis were nausea (OR: 2.21, 95%CI: 1.34-3.66), vomiting (OR: 0.82-15.6 range) and peritonism (OR: 1.80, 95%CI: 1.06-3.04). US, CT and MRI have all been used to successfully diagnose AIP. Laparoscopic appendicectomy has been safely undertaken in pregnancy. CONCLUSION: Appendicitis will continue to challenge the diagnostic acumen of surgeons. Whilst useful, consensus regarding the safety of laparoscopy, CT and MRI in pregnancy is yet to be achieved.
