The aim of this study was to investigate the safety and clinical efficacy of mini-laparoscopic pyeloplasty in treating ureteropelvic junction obstruction (UPJO) in infants. We retrospectively analysed the clinical data of 66 infants with UPJO from January 2013 to August 2018 at our hospital. They were divided into the laparoscopic surgery group (group A) and the open surgery group (group B), depending on the surgical method. The bleeding volume, analgesia duration, postoperative hospitalization duration, and incision length in group A were significantly less than those in group B (p <.05). The incidence of incision dehiscence was 0% in group A and 11.7% in group B (p =.045). At the postoperative follow-up, the incidence of anastomotic stenosis was 6.2% in group A and 5.9% in group B (p =.719). The anteroposterior diameter and glomerular filtration rate were significantly improved at the one-year follow-up, but there was no significant difference between the groups (p >.05). Mini-laparoscopic pyeloplasty to treat UPJO in infants has the same early clinical efficacy and safety as open surgery, and this procedure has the advantages of fewer incisions, less pain, quicker recovery, and better cosmetic outcomes.

The purpose of this study was to summarize the clinical experience with laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle for inguinal hernias in girls. A total of 462 girls with inguinal hernias participated in this study from January 2013 to June 2019. Laparoscopic percutaneous extraperitoneal closure of the internal ring via an epidural needle was used to treat these patients. All 462 girls with an inguinal hernia successfully underwent laparoscopic surgery. The operative times for unilateral and bilateral inguinal hernias were 15 (11–25) minutes and 23 (18–33) minutes, respectively. All patients were discharged 1–2 days after the operations. During the hospitalization and follow-up periods, none of the following complications were observed: hernia recurrence, umbilical hernia, abdominal wall vascular injury, intestinal injury or bladder injury. However, there were six patients with complications: two cases of poor healing of the umbilical incision, three cases of suture granulomas and one case of groin traction pain and discomfort. Laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle is a safe and feasible method for the treatment of inguinal hernias in girls. This method has the advantages of limited trauma, no scarring and a good cosmetic effect. [ABSTRACT FROM AUTHOR]
