3-7.5%

ERPC for postpartum haemorrhage
Parous uterus
Recent pregnancy in the past 6 months

5.1-5.7%
Risk perforation with TOP
0.52%
Risk perforation with PMB Ix with hysteroscopy
0.2-2%
prevention uterine perfromation
If premenopausal, OP hysteroscopy - give prostaglandins or misoprostol
Sae with sTOP
Slow careful cervical dilatation
Consider USS guidance
Which perforations can be managed conservatively
< 5mm
When laparoscopy required
> 5mm, tissues grasped avulsion attempted, bleeding
How to manage at laparoscopy?
Insert catheter
Small perforation with little bleeding do not need repair. If small bleed can cauterisation with diathermy
Larger - suturing
When to consider laparotomy
Continue haemorrhage, enlarging broad ligament haematoma
Needs suture but not laparoscopic surgeon available
