Insights
Transumbilical single-site laparoscopic percutaneous extraperitoneal closure (TSLPEC) is a safe and effective pediatric inguinal hernia repair. This minimally invasive technique offers shorter operating times, better cosmetic results, and lower recurrence and contralateral hernia rates compared to open surgery.
Area of Science:
- Pediatric Surgery
- Minimally Invasive Surgery
- Hernia Repair
Background:
- Numerous surgical techniques exist for pediatric inguinal hernias.
- Single-site laparoscopic procedures represent a novel approach.
Purpose of the Study:
- To analyze the safety and efficacy of single-site laparoscopic hernia repair in children.
- To compare this technique with traditional open surgery.
Main Methods:
- Transumbilical single-site laparoscopic percutaneous extraperitoneal closure (TSLPEC) was performed on 1583 children.
- Open inguinal hernia repair was performed on 355 children for comparison.
- Key outcomes included operating time, recurrence rate, and contralateral hernia incidence.
Main Results:
- TSLPEC demonstrated shorter operating times for both unilateral and bilateral repairs compared to open surgery.
- Recurrence rates were significantly lower in the TSLPEC group (0.4%) versus the open repair group (1.7%).
- No contralateral hernias developed after TSLPEC, compared to 5.6% in the open repair group.
Conclusions:
- TSLPEC is an effective and safe procedure for pediatric inguinal hernias.
- Advantages include reduced operating time, excellent cosmetic outcomes, and lower recurrence and contralateral hernia rates.
- TSLPEC is recommended as a routine treatment for pediatric inguinal hernias.
Background:
There have been numerous surgical procedures for inguinal hernia in children, and recently the novel technique of single-site laparoscopic procedure was introduced. This study aimed to analyze the safety and efficacy of single-site laparoscopic hernia repair in a large number of children, while compared with the traditional open surgery.
Methods:
From January 2012 to June 2015, we performed transumbilical single-site laparoscopic percutaneous extraperitoneal closure (TSLPEC) in 1583 patients, including bilateral hernia in 135 cases, and unilateral hernia in 1448 cases (left side in 582, right side in 866). From January 2007 to January 2010, we performed open inguinal hernia repair in 355 patients, including bilateral hernia in 52 cases, and unilateral hernia in 303 cases. Operating time, recurrence rate, incidence of contralateral hernia, and prevalence of contralateral patent processus vaginalis (cPPV) were recorded and compared.
Results:
A total of 1583 patients underwent TSLPEC, without conversion to open surgery. For unilateral repair, the average operating time in TSLPEC group was shorter than open repair group (19.3 ± 6.1 vs. 28.0 ± 8.9, p < 0.05), and it was much shorter than open repair group for bilateral repair (26.2 ± 9.5 vs. 49.8 ± 12.9, P p < 0). The left hernia had higher prevalence of cPPV than right hernia (48.1% vs. 38.5%, p < 0.05). The wound recovered well with good cosmetic appearance in TSLPEC group. Hernia recurrence occurred in seven cases (0.4%) of TSLPEC group, and six cases (1.7%) of open repair group ( p < 00.05). No contralateral hernia developed in TSLPEC group, while 17 cased (5.6%) had contralateral hernia in open repair group ( p < 00.05).
Conclusions:
TSLPEC is an effective and safe procedure for inguinal hernias with lots of advantages, including short operating time, simultaneous management of cPPV, excellent cosmetic appearance, low incidence of contralateral hernia, and low recurrence rate. This procedure could be recommended as a routine treatment for inguinal hernias in children.
