Abdominal myomectomy: A retrospective review of determinants and outcomes of complications at the University of Ilorin Teaching Hospital, Ilorin, Nigeria.
Background The aim of this study was to describe the pattern, outcomes, and determinants of perioperative complications of abdominal myomectomy at theUniversity of Ilorin Teaching Hospital, Ilorin, Nigeria. Methods This was a retrospective review of cases of abdominal myomectomy between January 2010 and December 2013. Data were obtained from ward and operating theatre case records and analysed using SPSS version 20. The continuous variables were analysed with Student’s t-test. The categorical variables were analysed with the chi-square test. P-values of 0.05 or less was taken to be significant. Results Total sampling yielded 204 cases, of which 170 records (80%) were adequate for analysis. Using criteria developed by Garry et al., major and minor complications occurred in 43.6% and 32.9% of procedures, respectively, while 23.5% of the patients had no complications. The commonest complication was intraoperative haemorrhage requiring blood transfusion. Mean estimated blood loss was 630.88 ± 392.42 mL. There were no cases converted to hysterectomy, and no deaths were recorded. Uterine size equivalent to 16 weeks’ gestation or more was significantly associated with heavier blood loss, blood transfusion, and fever (P = 0.034). Other significant determinants of major intraoperative haemorrhage with or without blood transfusion were menstrual flow of 6 days or more, preoperative anaemia, previous surgery, posterior incision, and surgery duration longer than 4 hours (P < 0.05). Conclusions Outcome of abdominal myomectomy is generally favourable even if uterine size is greater than 16 weeks by palpation. Nevertheless, patients should be counselled preoperatively on the risk of blood loss and the possibility of blood transfusion.
