Comparison of laparoscopic and open pediatric inguinal hernia repairs at two institutions

Laparoscopic Extraperitoneal Hernia Repair Versus Open Repair in Boys with Inguinal Hernia: A Meta-analysis

OBJECTIVE

Pediatric inguinal hernia is a common surgical problem in boys. Open hernia repair surgery (OH) has been traditionally used to treat this condition, but it leads to complications, such as testicular complications. Laparoscopic hernia repair by using the extraperitoneal method (LHE) is performed through the percutaneous insertion of sutures and extracorporeal closure of patent vaginalis processus; thus, injury to spermatic cord structures is avoided. However, a meta-analysis comparing LHE and OH is lacking.

METHODS

PubMed, EMBASE, and Cochrane Library databases were searched for relevant studies. A meta-analysis of the retrieved studies was performed, and a random-effects model was used to calculate the pooled effect size. The primary outcome was testicular complications, including ascending testis, hydrocele, and testicular atrophy. The secondary outcomes were surgical metachronous contralateral inguinal hernia (MCIH), ipsilateral hernia recurrence, and operation time.

RESULTS

In total, 6 randomized controlled trials (RCTs) and 20 non-RCTs involving 17,555 boys were included. The incidence of ascending testis (risk ratio [RR]: 0.38, 95% confidence interval [CI]: 0.18-0.78; p = 0.008) and MCIH (RR: 0.17, 95% CI: 0.07-0.43; p = 0.0002) was significantly lower in LHE than in OH. The incidence of hydrocele, testicular atrophy, and ipsilateral hernia recurrence did not differ between LHE and OH.

CONCLUSION

Compared with OH, LHE led to fewer or equivalent testicular complications without increasing ipsilateral hernia recurrence. Moreover, MCIH incidence was lower in LHE than in OH. Hence, LHE could be a feasible choice with less invasiveness for inguinal hernia repair in boys.

Comparison of Two Laparoscopic Techniques in Management of Pediatric Inguinal Hernias

Introduction: Many studies focus on comparing outcomes of the open method for inguinal hernia repair (IHR) and the laparoscopic method. However, few studies compare different laparoscopic techniques. With over a dozen different techniques described in the literature for laparoscopic IHR, significant opportunities exist to study the efficacy of each technique. We investigated outcomes of a subcutaneous endoscopically assisted transfixion ligation (SEATL) technique and a percutaneous internal ring suturing (PIRS). Materials and Methods: After receiving institutional review board approval, we completed a retrospective chart review of IHR performed at our pediatric tertiary care center between September 2015 and May 2020. We included all patients under the age of 18 years. We separated laparoscopic repairs from total repairs. Laparoscopic repairs were further divided into their respective techniques. Factors involving patient demographics, operative details, and postoperative complications were statistically analyzed using SPSS. Results: There was a total of 131 IHRs performed with SEATL and 124 IHRs performed with PIRS. Median operative time (minutes) differed significantly (P = .001) with SEATL at 49 (28-66) and PIRS at 55 (37-76)] minutes. Significantly more incarcerated hernias were repaired with PIRS (n = 13) than with SEATL (n = 3, P = .006). SEATL had a higher number of postoperative complications; the most significant were granulomas (n = 3, P = .09) and recurrent hernias (n = 12, P < .001). Conclusion: SEATL had a significantly higher number of postoperative complications. This may be a result of multiple factors including but not limited to the absence of electrocautery, a shorter median operative time, and utilization of absorbable suture. Modifications have been made to this technique to reduce risk of postoperative complications.

Laparoscopic inguinal hernia repair in children: Article review and the preliminary Maltese experience

BACKGROUND

In the past two decades, laparoscopy has provided an alternative approach to inguinal hernia repair. The aim of this review is to carry out a retrospective systematic analysis of articles dealing with laparoscopic hernia repair in children and a review of the Maltese experience.

METHODS

Data was obtained from publications from 2002 to 2019. The endpoints include: patient demographics, clinical presentations, laparoscopic tools, ports, suture used, technical remarks, length of surgery, hospital stay, complications and follow-up.

RESULTS

32 studies were included with a total of 10,183 patients. Most articles documented the use of 1 port. Length of surgery ranged from an average of 10 to 138 min. Ipsilateral recurrences were reported in 0.83% of cases, while 0.17% required conversion to open.

PRELIMINARY MALTESE EXPERIENCE

In our centre, a population of 514, 564 is covered (16% under the age of 18). A total of 14 cases of laparoscopic inguinal hernia repair were carried out from August 2018 till October 2020. The neonatal laparoscopic set-up involves a 30⁰ laparoscope, inserted via a 5 mm umbilical port, with 2 stab incisions allowing the use of 3 mm devices. Intra-corporeal purse string suture technique is used. The length of surgery ranged from 1 hr to 2 hr 30 min. There was 1 case of ipsilateral recurrence and another requiring conversion to open surgery.

CONCLUSIONS

Laparoscopic inguinal hernia repair in children is a versatile and safe procedure that can be carried out with minimal complications and low reoperation rates.

Laparoscopic Hernia Repair with the Extraperitoneal Approach versus Open Hernia Repair in Pediatric Inguinal Hernia: A Systematic Review and Meta-Analysis

OBJECTIVE

This systematic review and meta-analysis investigated the feasibility and effectiveness of laparoscopic hernia repair with the extraperitoneal approach in pediatric inguinal hernias.

SUMMARY BACKGROUND DATA

Inguinal hernia repair is the most common operation in pediatric surgical practice. Although open hernia repair (OHR) is a well-established procedure with good outcomes, studies have reported acceptable or even better outcomes of laparoscopic hernia repair with the extraperitoneal approach (LHRE). However, a meta-analysis comparing LHRE with OHR is lacking.

METHODS

PubMed, EMBASE, and Cochrane Library databases were searched for randomized controlled trials (RCTs) and comparative studies (prospective or retrospective). Outcomes were metachronous contralateral inguinal hernia (MCIH), hernia recurrence, surgical site infection, operation time, and hospitalization length. A meta-analysis was performed, and risk ratios (RR), weighted mean difference (WMD), and 95% confidence intervals (CI) were calculated using random-effects models.

RESULTS

Five RCTs and 21 comparative studies involving 24,479 patients were included. Lower MCIH incidence (RR: 0.11, 95% CI: 0.07 to 0.17; p < 0.00001) and a trend of shorter operation time (WMD: -11.90 min, 95% CI: -16.63 to -7.44; p < 0.00001) were found in the LHRE group. No significant differences in ipsilateral recurrence hernias, surgical site infection, and length of hospitalization were found between the groups.

CONCLUSIONS

LHRE presented lower MCIH incidence and shorter operation times, with no increase in hernia recurrence, surgical site infection, or length of hospitalization. As more surgeons are increasingly becoming familiar with LHRE, LHRE would be a feasible and effective choice for pediatric inguinal hernia repair.

[Laparoscopic phelps approach in children with inguinal hernia: a retrospective comparative study]

OBJECTIVE

To evaluate the effectiveness of a new method of inguinal hernia repair in children (PHELPS) first proposed by the authors compared to another laparoscopic method (SEAL).

MATERIAL AND METHODS

The study demonstrated the results of laparoscopic treatment of 729 patients with inguinal hernias. Of these, 255 patients underwent PHELPS procedure. Other 474 patients underwent SEAL procedure. The difference between both methods is that hernial ligature is passed around the hernial sac in case of PHELPS. SEAL procedure implies capture of tissues of anterior abdominal wall (muscles and aponeurosis) into this knot. We analyzed whether this factor can lead to less incidence of recurrence and hydrocele.

RESULTS

Both groups were comparable by age, body weight and gender. Median of surgery time including correction of unilateral and bilateral hernia was similar (20.0 [10.0; 20.0] min versus 15.0 [15.0; 20.0] min; p=0.666). We found faster patient recovery after PHELPS procedure for inguinal hernia including much less doses of postoperative analgesia (1.0 [1.0; 1.0] versus 1.0 [1.0; 2.0]; p<0.001) and shorter hospital-stay (8.0 [8.0; 8.0] hours versus 8.0 [8.0; 9.0] hours; p=0.010). There were no significant differences in the incidence of postoperative hydrocele (0 versus 6; p=0.097). Nevertheless, recurrence rate differed significantly (0 versus 17; p=0.001).

CONCLUSION

PHELPS procedure is characterized by lower incidence of recurrence and accelerated postoperative recovery compared to SEAL technique.

Results of using the method of full extraperitoneal endoscopically assisted ligation of the hernial sac with inguinal hernia in children

BACKGROUND/PURPOSE

The aim of this study was to evaluate the effectiveness of a new technique for inguinal hernia repair in children: pediatric hernia extra-peritoneal ligation and percutaneous suturing (PHELPS) in comparison with another laparoscopic technique, subcutaneous endoscopically assisted ligation (SEAL).

METHODS

We demonstrate the results of laparoscopic treatment of 680 patients with inguinal hernias. Of these, 206 patients were operated using the new PHELPS technique. The remaining 474 children received the SEAL technique. The difference between the methods is that PHELPS consists of ligating the hernia around the neck of the hernial sac, including an intra-peritoneal component (aponeurosis and muscles), while the SEAL technique ligates the hernia sac only. We examined whether this factor may lead to more recurrence and hydrocele in the SEAL technique.

RESULTS

Both groups of patients were comparable in terms of age, body weight at the time of surgery, and gender. The average total duration of inguinal herniorraphy, including the time of surgery in patients with one-and two-sided hernia localization, was comparable in both groups (17.50 min versus 17.22 min; p = 0.518). The study demonstrated a faster recovery of patients after using the PHELPS technique for the treatment of inguinal hernias, consisting in a statistically significantly lower number of doses of postoperative analgesia (1.01 versus 1.31; p < 0.001) and a shorter time of patient stay in the hospital (8.06 h versus 8.78 h; p = 0.031). Despite the fact that there were no statistically significant differences in the frequency of postoperative hydrocele (0 versus 6; p = 0.090), we found a statistically significant difference between the groups in terms of recurrence (0 versus 17; p < 0.001).

CONCLUSIONS

The PHELPS technique shows improved results in terms of recurrence and hydrocele as compared to SEAL.

Is the open approach superior to the laparoscopic hernia repair in children? A retrospective comparative study

Background

For many years now, inguinal hernia repair in children has been done either by the open approach or laparoscopically with laparoscopy having the edge in terms of cosmesis and postoperative pain. However, recent studies have called for a return of the open approach as it had a comparable result to laparoscopy with lesser cost. This study aims to compare the outcomes of the two approaches at our institution.

Methods

This is a retrospective analysis of the prospectively collected data of all patients aged between 6 months and 13 years who underwent open or laparoscopic inguinal hernia repair in the period between January 2017 and July 2019 at our institution.

Results

155 patients were included in the study. 100 (64.5%) underwent open inguinal repair while 55 (35.5%) were done laparoscopically. There was no significant difference in the postoperative complications between the open and laparoscopic groups (P = 0.66). The overall mean operative time for the laparoscopic group and the open group is (45.7 ± 15.2, 45.5 ± 15.4 min, P = 0.83) respectively. However, a subgroup analysis showed a statistical difference in the operative time in bilateral hernias favoring the laparoscopic approach, (44 ± 13.2, 63.2 ± 26.4 min respectively, P = 0.049). Laparoscopy was also associated with shorter times to full recovery compared to the open group (4.7 days, 7.5 days, P = 0.013). Surprisingly, there was no difference in the cosmetic outcome between the two groups which is contrary to the published literature.

Conclusions

Laparoscopic inguinal hernia repair in children is a feasible and reproducible procedure. It permits the evaluation of the contralateral groin without further incisions. In our study, laparoscopy was superior in terms of operative time in bilateral hernias and the time to recovery. Finally, an added benefit to laparoscopy is that it offers more training opportunities for fellows and residents to improve their laparoscopic skills.

High ligation in adolescents: Is it enough?

BACKGROUND

In adults, the gold standard for surgical repair of an inguinal hernia is a mesh repair, whereas, in children, the standard is high ligation of the hernia sac. However, adolescents represent a "gray zone" between children and adults, and there is no consensus on the most appropriate operation for inguinal hernias in these patients. We aimed to describe the outcomes in adolescents undergoing high ligation for inguinal hernia repair and determine what factors may portend an increased risk of recurrence in this population.

METHODS

A retrospective cohort study was performed of all children that underwent open high ligation for an inguinal hernia at our tertiary children's hospital from January 2000 to January 2018, who were 12 to 18 years old at the time of surgery. We compared the patient demographic data, medical history, and repair characteristics for the cohort of hernias that developed a recurrence to the cohort that did not.

RESULTS

During our study period, 256 adolescent patients underwent repair with 11 of those patients having both sides repaired for a total of 267 hernias repaired. The median age at surgery was 14.7 years, and 83.9% of the hernias were in male patients. There was a 6.0% recurrence rate, and all patients that developed recurrence underwent a reoperation. The median time from surgery to reoperation for recurrence was 3.1 years. Patients with recurrence were more likely to have cardiac (25.0% vs. 5.8%, p = 0.02) and gastrointestinal comorbidities (25% vs. 7.1%, p = 0.01). There were no other significant differences between the two cohorts.

CONCLUSION

High ligation of the hernia sac in adolescents is effective and has an acceptable risk of recurrence while avoiding any additional morbidity that may come from the use of mesh. Patients with cardiac and gastrointestinal comorbidities should be counseled on the higher risk of recurrence.

Transabdominal preperitoneal repair for an adolescent patient with Hunter syndrome: a case report

Background

Hunter syndrome is an X-linked disorder caused by a deficit of the lysosomal enzyme iduronate-2-sulfatase and is associated with many disorders. Patients with Hunter syndrome often develop inguinal hernias in early childhood and undergo Potts’ method, laparoscopic percutaneous extraperitoneal closure (LPEC), or laparoscopic direct suture.

Case presentation

An 18-year-old male visited our hospital for evaluation of a palpable mass in the right groin hernia. Computed tomography revealed a right indirect inguinal hernia. He had a history of repeated admission to our hospital and pediatric treatments for pneumonia, heart failure, and convulsions after birth. Because he has stopped growing and a wide hernia orifice was present with no apparent hernia on the left side, we performed TAPP repair. During surgery, we noted softness of the abdominal wall, similar to children’s abdominal wall, and laparoscopy revealed well-developed veins around the spermatic cord and testicular artery. The softness of the abdominal wall made insertion of the trocars difficult and well-developed veins needed our special care to avoid hemorrhage. After surgery, the patient developed a convulsion due to Hunter syndrome and subsequent aspiration pneumonia; however, he recovered with medical treatments administered in cooperation with specialists and was discharged on postoperative day 9.

Conclusion

This is the first reported patient with Hunter syndrome whose inguinal hernia was treated by TAPP repair. TAPP repair might be a useful procedure even for adolescent patients with Hunter syndrome, although adequate care is needed for symptoms due to Hunter syndrome.
