The B-Lynch Suture invented by a reknowned UK obstetrician born in Sierra Leone

The B-Lynch Suture invented by a reknowned UK obstetrician born in Sierra Leone

Sometimes, the answer to severe hemorrhage turns out to be not a device or gadget, but an innovative surgical technique--in this case the B-Lynch suture.

Over 100,000 women die of postpartum hemorrhage (PPH) each year, accounting for 35% of all maternal deaths. An estimated [90%](http://globalhealth.kff.org/GHIR/Conditions/Maternal-Hemorrhage.aspx#_edn6) of these cases are caused when the uterus is unable to adequately contract after childbirth (uterine atony).

When “conservative management” using massage, [pressure packing](http://maternova.net/health-innovations/adapt) and drugs such as [oxytocin](http://maternova.net/health-innovations/aerosol-oxytocin) or [misoprostol](http://maternova.net/health-innovations/misoprostol-hemorrhage) fail to stop severe bleeding, healthcare providers must often resort to radical surgical intervention, including hysterectomy (the removal of the uterus). In addition to loss of fertility, these interventions can cause a range of [complications](http://www.ncbi.nlm.nih.gov/pubmed/15814393) and even death.

In attempt to avoid hysterectomy, Christopher Balogun-Lynch developed an innovative surgical technique to treat atonic PPH. Using this method, a continuous suture is used to envelop and mechanically compress the uterus. The Global Library of Women’s Medicine provides a [poster](http://www.glowm.com/?p=glowm.cml/section_view&articleid=138) explaining the procedure in more detail. Since its invention in 1997, the B-Lynch technique has been used successfully in approximately [1,300](http://www.ncbi.nlm.nih.gov/pubmed/15814393) cases worldwide.

For example, in a review of PPH cases in [Pakistan](http://www.pmrc.org.pk/pph.htm), authors favored the B-Lynch technique for its safety, simplicity, lifesaving potential and ability to preserve fertility. The suture was successful for cases of PPH after both vaginal and caesarian deliveries. As a result, the authors believe the B-Lynch suture “should be considered as a first line surgical treatment before…hysterectomy”.

In [Singapore](http://smj.sma.org.sg/5007/5007a4.pdf), one study indicated that out of 5,470 deliveries, 100 women experienced PPH. Only seven of these women were treated with the B-Lynch suture, successfully avoiding hysterectomy in five cases. The authors thus conclude that the B-Lynch technique is an effective procedure for managing PPH before any radical surgery is considered. “It has the advantage of being applied easily and rapidly, and should be taught to all trainees and registrars in obstetrics,” they argue.

Since 1997, several modifications of the B-Lynch method have been developed, for which there is a growing body of [supportive evidence](http://www.bhj.org/journal/2008_5002_april/download/page-205-211.pdf). We're curious to know how standard the teaching of the B-lynch suture is in the training of obstetrician/gynecologists and others in Africa, Asia and Latin America.

We hope it goes without saying that this is a procedure meant for surgeons! Don't try this at home!
