Bipolar sealing devices versus endoscopic vascular staplers during laparoscopic splenectomy in children with benign hematological diseases

Abstract

Background: Splenectomy, whether open or laparoscopic, is considered a step of management in many children with benign hematological diseases such as immune thrombocytopenia, thalassemia, autoimmune hemolytic anemia, and spherocytosis. The major challenge during laparoscopic splenectomy (LS) is the rich blood supply of the spleen. Many techniques were considered to control the vascular supply of the spleen. Staplers, clips, either titanium or hemoclips, a bipolar sealing device (BSD), or ultrasonic shears were all used to complete LS. We aimed to compare the results of using BSD versus endoscopic staplers for vascular control of the pedicle during LS.

Patients and methods: The study was carried out on 30 children with benign hematological diseases who presented to the Pediatric Surgical Unit. They were grouped randomly into two groups: group A and group B. Group A included 15 patients who were subjected to LS in which BSD was used for vascular control, whereas group B included 15 patients subjected to LS in which endoscopic staplers were used for vascular control of the pedicle.

Results: The mean age of the children in group A was 9.60 years, whereas the mean age of the children in group B was 10.40 years. In group A, the mean estimated amount of blood loss was 72.27 ml. However, this was 80.67ml in group B. In group A, the mean operative time required was 39.00 min, whereas it was 56.27 min in group B. The indications for splenectomy were thalassemia in 15 cases (seven for group A and eight for group B), idiopathic thrombocytopenic purpura in 13 cases (seven for group A and six for group B), and spherocytosis in two cases (one for each group). The mean splenic size in group A was 10.43 cm, whereas it was 11.73 cm in group B.

Conclusion: LS has evolved over the last decade because of the advancements of BSDs and endoscopic staplers. According to our data the use of LigaSure reduces the overall operative time, operative blood loss, and associated complications compared with the use of staplers.
