Abstract
Background:
This study aimed to review our 25-year experience with pediatric laparoscopic splenectomy (LS) and describe tips, tricks, and technical considerations.
Methods:
The records of 121 children, undergoing minimally invasive splenectomy in the last 25 years (1996–2021), were retrospectively reviewed. Median patient age was 10.2 years (range 7–17). The patients were grouped according to the period: G1 (1996–2005) included 31 patients undergoing open splenectomy using left subcostal minilaparotomy (G1a) and 28 receiving LS using supine position (G1b); G2 (2006–2021) included 62 patients undergoing LS using lateral decubitus. A five-trocar technique was adopted in G1b, with the spleen removed through a Pfannenstiel incision. In G2, we preferred to use lateral decubitus, 10-mm 30° optic, only four trocars, and sealing devices. In such cases, the spleen was placed in an endobag, finger-fragmented, and extracted through the umbilicus. Furthermore, indocyanine green (ICG) fluorescence was used in the last 4 G2 patients to clearly identify the vascular anatomy.
Results:
The median operative time was 65 minutes in G1a, 125 in G1b, and 95 in G2. Complications occurred intraoperatively in 14 cases (11.5%): 5 bleedings during dissection (G1b), 4 endobag breakages during spleen removal (G2); 3 spleen capsule breakages during removal (G1a); and 2 instrumentation failures (G2). No conversions to open occurred. Median hospital stay was 6 days in G1a and 4 days in G1b and G2.
Conclusions:
LS is a standardized and effective procedure in children and is preferable to mini- or conventional open splenectomy. Our 25-year experience showed that major complications may occur even in expert hands, mainly during hilar dissection or spleen extraction. Technically, sealing devices and ICG fluorescence were helpful to perform a safer and faster procedure. We believe that lateral decubitus and 30° optic should be considered technical key points to provide excellent organ exposure and easier dissection of hilar structures.
