INTRODUCTION: Laparoscopic pyloromyotomy is now an accepted procedure for the treatment of pyloric stenosis. However, it is clear that during the implementation period there are significantly higher incidences of mucosal perforation and incomplete pyloromyotomy. We describe how we introduced a new laparoscopic procedure without the complications associated with the learning curve. MATERIALS AND METHODS: Five consultants tasked one surgeon to pilot and establish laparoscopic pyloromyotomy before mentoring the others until they were performing the procedure independently; all agreed to use exactly the same instruments and operative technique. This involved a 5mm 30-degree infra-umbilical telescope with two 3mm instruments. Data were collected prospectively. RESULTS: Between 1 January 2013 and 31 December 2017, 140 laparoscopic pyloromyotomies were performed (median age 27 days, range 13-133 days, male to female ratio 121:19). Fifty-five per cent of procedures were performed by trainees. Complications were one mucosal perforation and one inadequate pyloromyotomy. There were no injuries to other organs, problems with wound dehiscence or other significant complications. The median time of discharge was one day (range one to six days). CONCLUSION: Our rate of perforation and incomplete pyloromyotomy was 1.4%, which is equivalent to the best published series of either open or laparoscopic pyloromyotomy. We believe that this resulted from the coordinated implementation of the procedure using a single technique to reduce clinical variability, increase mentoring and improve training. This approach appears self-evident but is rarely described in the literature of learning curves. In this age of increased accountability, new technologies should be incorporated into routine practice without an increase in morbidity to patients.
