Background: Despite recent advances in anaesthetic, perinatal and preoperative care, surgical intervention during pregnancy may still result in fetal loss from either spontaneous abortion (especially in the first trimester) or premature labor (especially in the third trimester). This study was aimed at determining the factors that affect fetal and maternal outcome following emergency non-obstetric abdominal surgery in pregnancy.
Methods: We reviewed all cases of emergency non-obstetric abdominal surgery performed on pregnant women at Obafemi Awolowo University Teaching Hospital complex from January 1991 and December 2006. The socio-demographic characteristics, obstetric history, diagnosis and outcome of management were documented and analyzed.
Results: A total of 46 pregnant patients presented with various conditions necessitating emergency non-obstetric abdominal surgery during the study period. Their ages ranged from 23 to 39 years with a mean age of 29.33 +/-4.904. Six (13%) of the patients presented during the first trimester, 32 (69.6%) patients during the second trimester and 8 (17.4%) were seen in the third trimester. Thirty-two (69.6%) patients presented with features of acute appendicitis out of 12 had ruptured appendicitis and 8 had appendicular abscess. Eight (17.4%) had intestinal obstruction, 5 (10.8%) had haemoperitonueum from abdominal injury and 1 (6.7%) had an ectopic foetus in bladder. Four (8.8%) mothers and 20(43.5%) babies died. Factors affecting maternal outcome included parity (P=0.010), duration of symptoms (P<0.0001) and delay in surgery (P<0.0001) while the factors affecting fetal outcome include maternal age (P<0.0001), booking status (P<0.0001), educational status (P<0.010), parity (P<0.040), gestational age (P=0.048) and delay in surgery (P=0.016).
Conclusion: Complicated appendicitis is the most common indication for abdominal surgery in pregnancy in our center. High foetal loss seen in this study can be reduced by early presentation of the patients, early booking and high index of suspicion and prompt treatment by the attending surgeon.
