HISTOMORPHOLOGICAL STUDY OF THE UTERUS IN 64 PERIPARTUM HYSTERECTOMY SPECIMENS.
Background: Peripartum hysterectomy is a life saving procedure performed for intractable obstetric haemorrhage. Uterine atony, rupture, abnormal placentation, retained products etc. are common indications. With the rise of caesarean sections, the incidences of peripartum hysterectomies are increasing worldwide. The aim of the present study is to evaluate the histomorphological findings in peripartum hysterectomy specimens received during a five year period. Material and Method: In this hospital based cross-sectional study during a five year period (Jan 2014 –Dec 2018), 64 peripartum hysterectomy specimens received in the department of Pathology, RIMS, Imphal, Manipur were included. The gross and histomorphological findings were evaluated, studied, statistically analysed and compared with other studies. Results and Observation: The various histomorphological findings were abnormal placentation 28 (43.7%), uterine atony 15 (23.5%), uterine rupture 14 (21.8%), retained placenta/product 6 (9.3%) and subinvolution 1(1.5%). Abnormal Placentation and Placenta cretas were the most common finding in the present study. The lower uterine segment was the most common abnormal site of placental implantation. The age ranged from 21 to 45 years, with majority of the cases were in the 30-39years age group. History of previous caesarean section was noted in 20 cases (31.2%). The relative risk of abnormal placentation was 2.5 times higher in those cases with prior history of caesarean section. Rupture was most commonly associated with multiparous women. Co-morbid overlapping features were seen in few cases. Conclusion: Histopathological diagnosis not only confirmed the clinico-radiological impression, but also highlighted the other co-morbid associations that caused the intractable haemorrhage which warranted a peripartum hysterectomy.
