Single-Incision Pediatric Endosurgery (SIPES) Splenectomy: A Case-Control Series

Background/Purpose: Single-incision pediatric endosurgery (SIPES) is gaining popularity. The aim of this study was to review the authors' experience with SIPES splenectomy and compare it with conventional laparoscopic splenectomy. Subjects and Methods: After institutional review board approval, data on SIPES splenectomy in children were collected prospectively. The study group was compared with a control group of patients who were retrospectively identified as having undergone conventional laparoscopic splenectomy during the same time period. Results: Sixteen children underwent SIPES splenectomy. Ages ranged from 1 to 15 years, with a median of 7 years, and weights were between 10 and 70 kg, with a median of 24 kg. The control group was similar in age and weight characteristics. The most common diagnoses were hereditary spherocytosis, sickle cell disease, and immune thrombocytopenic purpura. There were two conversions to open splenectomy in the SIPES group and one in the laparoscopic group. Operative times were 40-190 minutes (median, 84 minutes) in the SIPES group and 51-154 minutes (median, 99 minutes) in the conventional laparoscopic group. Conclusions: The SIPES technique is well suited for splenectomy. Despite instruments and camera being in-line, working angles are not compromised, and visualization is adequate. Operating time and hospital stay are comparable to those with standard laparoscopic splenectomy, but the cosmetic result may be superior.
