Introduction: Introduction: Appendicitis in pregnancy is rare and its diagnosis is a challenge as the clinical presentation may be altered in pregnancy. Early diagnosis of appendicitis is vital for a favourable pregnancy outcome.
Aim: To study clinical features, radiological findings, surgical, histopathological and pregnancy outcomes in cases of acute appendicitis complicating pregnancy.
Materials and Methods: This retrospective study was conducted in Christian Medical College and Hospital, a Tertiary Care Centre in the Department of Obstetrics and Gynaecology, Tamil Nadu, India. We reviewed the medical records and computerized database of a large tertiary care center between January 2007 and December 2016 and retrieved 34 cases of appendicitis complicating pregnancy. During this period there were 1,23,938 deliveries in the Department of Obstetrics and Gynaecology and a total of 632 women had undergone appendicectomy, in the Department of Surgery. The details of the demography, clinical presentation, lab investigations, imaging, surgical findings, treatment, pathology and pregnancy outcomes were assessed and collated from case notes. Standard clinical, radiological and laboratory diagnostic criteria were used to establish the diagnosis of appendicitis. Categorical variables were summarised as frequencies and percentages. Quantitative variables were summarised as mean and standard deviation for normally distributed variable or median and IQR for skewed variables. Diagnostic accuracy were given with 95% confidence interval.
Results: Mean gestational age at diagnosis was 18 weeks. Mean duration between onset of pain to admission was 1.77±1.08 days. The average MANTRELS score comprising of symptoms, signs and laboratory findings was 5. Ultrasound imaging was done for all cases. Thirty two women underwent surgery. Two women were managed conservatively. Thirty one women had histopathological findings of the appendix. The sensitivity of ultrasound was 87% (95% CI: 66.4% - 97.2%), and specificity was 100%. The positive predictive value was 100% and negative predictive value was 40%.
Conclusion: Clinical judgment complemented with ultrasound imaging is optimal in diagnosis of appendicitis. Patients presented within one to two days of abdominal pain at a mean gestational age of 18 weeks. Most women had appendicectomy within 2.5 days of onset of symptoms with favourable perinatal outcome.
