B-Lynch suture for the treatment of uterine atony

Introduction: Over 125,000 women die of postpartum haemorrhage (PPH) each year, with the commonest cause being uterine atony (75–90 percent). Failing conservative management, hysterectomy is usually the final resort. In 1997, Christopher B-Lynch devised an innovative technique to treat uterine atony, and it has been widely used around the world since its original report. However, there are hardly any reports of this technique being utilised in East Asian countries, including Singapore. Our study reviews the cases in which the B-Lynch suture was used to treat uterine atony, and the clinical outcomes of these cases. Methods: A retrospective study of data of all women who delivered between May 2004 and June 2007 was collected from the department’s database, to identify patients who had undergone the B-Lynch procedure. Primary PPH is defined as a blood loss of more than 500 ml at or within 24 hours of delivery. Results: There were a total of 5,470 deliveries during this period, with primary PPH occurring in 100 cases. The B-Lynch procedure was performed in seven women, avoiding the need for a hysterectomy in five cases. Conclusion: Our series of cases treated with the B-Lynch procedure showed that it is an effective method of containing PPH. It has the advantage of being applied easily and rapidly, and should be taught to all trainees and registrars in obstetrics. It should be attempted when conservative management of PPH fails and before any radical surgery is considered.
