Uterine malformationsUterine malformationsBackgroundBackground
• Uterus forms by fusion of paramesonephric ducts @ 10/40
• Abnormalities in resorption of the fused midline tissues by 20/40 can result in formation of septae of various lengths and position
• Partial septum limited to uterine fundus; complete septum down to Cx canal or Vagina
• May be double cervix and urological tract anomalies (10-20%)

Key points:division of septumKey points:division of septumGeneral principlesGeneral principles
• Endometrial preparation with GnRH analogues helpful
• Control laparoscopy essential
• Second-look hysteroscopy is advisable to confirm integrity of cavity • Can be performed as OP hysteroscopy
• A two stage procedure may be required• Better to resect less at first attempt if any doubt re depth of
resection

Key points:division of septumKey points:division of septumDegree of resectionDegree of resection
• Look for change from avascular white tissue of septum to vascular pink myometrial tissue
• Relationship of resection to tubal ostia
• Proximity of the resection to the uterine serosa as judged by control laparoscopy
• Aim to leave more rather than less myometrium(2cm depth) to minimise risk of subsequent uterine rupture in pregnancy

Lecturer’s opinion• Simplicity of hysteroscopic metroplasty
and 70-80% quoted rates of miscarriage in women with septae weighs argument in favour of recommending surgery for now

The Way ForwardThe Way Forward
• BUT….
• Women have acted as their own controls in studies thus far
• Prospective RCTs are needed to confirm benefits of septum resection v conservative management after definitive diagnosis of septum • in women with and • in women without pre diagnosis pregnancy loss
• Improved imaging will avoid the need to confirm diagnosis by laparoscopy prior to randomisation

Conclusions Conclusions –– SeptaeSeptae
• Vital to make correct diagnosis initially • Division of bicornuate uterus would have disastrous consequences!
• Hysteroscopic metroplasty is now the surgical method of choice for uterine septae ?instrument (RCT data needed)
• Cases should be carefully audited ?major centres only performingprocedures to gain experience
• Data suggest significant improvement in reproductive outcome following septum removal
• Now time for a multinational randomised prospective study to confirm benefits of resection v conservative management
