Purpose Lower transverse abdominal incisions are typically used by obstetricians/gynecologists and colorectal surgeons. The suture technique and choice of material when closing the abdomen is an essential factor to decrease the risk of incisional hernia. We conducted a nationwide survey among obstetricians/gynecologists and colorectal surgeons investigating the surgical handling of the fascia, rectus muscle, subcutis, peritoneum, and skin, in lower transverse incisions. Methods All departments of obstetrics/gynecology and departments of surgery performing colorectal surgery in Denmark were invited to participate. An online questionnaire was sent to consultant obstetricians/gynecologists and colorectal surgeons. The survey consisted of demographic information together with questions on surgical details. The study was reported according to STROBE guidelines. Results A total of 252 (64.5%) consultants provided a complete response to the survey. We found that 98.0% of the colorectal surgeons and 65.8% of the obstetricians/gynecologists used monofilament suture when closing the fascia. The majority of the colorectal surgeons used continuous suture and small bites technique. This was only the case for half of the obstetricians/gynecologists. Approximately two thirds of the colorectal surgeons and one third of the OB/GYN used the suture length to wound length ratio > 4:1. Furthermore, we found significant differences between the groups in the handling of subcutis, peritoneum, and skin. Conclusion We found significant variation in abdominal wall closure techniques in lower transverse incisions. Disagreement between the current guidelines within the specialties together with insufficient evidence on the closure of lower transverse incisions emphasizes the need for education as well as further studies.
