Is pneumoperitoneum necessary for single-incision laparoscopy-assisted appendectomy for pediatric appendicitis?

Is pneumoperitoneum necessary for single-incision laparoscopy-assisted appendectomy for pediatric appendicitis?

Asian Journal of Endoscopic Surgery 2019:

Several studies have reported the treatment of pediatric appendicitis with single-incision laparoscopy-assisted appendectomy using a muscle hook without pneumoperitoneum to lift the abdominal wall. However, very few studies have investigated the advantages of this procedure. We examined the utility of this procedure in our department. This study included 33 children with appendicitis who underwent single-incision laparoscopy-assisted appendectomy at our hospital from April 2011 to March 2018. Patients were divided into two groups depending on whether they underwent the procedure with pneumoperitoneum: the no pneumoperitoneum group (n = 12) and the pneumoperitoneum group (n = 21). The clinicopathological factors and surgical costs were compared between the two groups. In the pneumoperitoneum group, the procedure was initiated in four patients by lifting the abdominal wall but was changed to include a pneumoperitoneum because of difficulty. There were no significant differences between the two groups with regard to age, sex, or pathological severity. CT revealed a significant difference in the distance from the appendicular root to the umbilicus between the groups. There was a significant difference in the operative duration, but not in estimated blood loss or length of postoperative hospital stay. Complications were observed in one patient in each group. There was a significant difference in cost between the two groups. Single-incision laparoscopy-assisted appendectomy without pneumoperitoneum is less expensive because certain supplies and CO2 are not required. Because there were no differences in the length of postoperative hospital stay or complications, this procedure may be safe in cases that are expected to be mild.
