Case series
The six case series are summarised in Table 2 along with
our case series and the two previous literature reviews. Of
the 34 cases, there were 17 cases of adhesional SBO (50%),
four cases of intussusception (12%), five cases of internal
hernia (15%), three cases of volvulus (9%) and five cases
where the aetiology was not documented.19 In cases where
the gestational age was disclosed (n=29), 2 cases of SBO
occurred in the first trimester, 13 in the second trimester
and 14 in the third trimester. There were seven fetal deaths
in total, three of which were in cases of adhesional SBO, and
one maternal death in a case of volvulus causing SBO.
