The laparoscopic approach for repair of indirect inguinal hernias in infants and children

Laparoscopic Repair of an Incarcerated Left Ovary, Hemi-Uterus, and Salpinx Within A Left Inguinal Hernia

Inguinal hernia repair is one of the most common operations performed by pediatric surgeons. These hernias typically present as asymptomatic or symptomatic swellings in the groin, extending into the labia in girls or the scrotum in boys. Surgical repair is indicated as these hernias do not spontaneously close and carry a risk of incarceration. We report a case of an extremely rare finding at the time of laparoscopic inguinal hernia repair in a preteen girl, highlighting the variable clinical presentation of this common condition and the laparoscopic approach to repair.

Laparoscopy is increasingly used for pediatric inguinal hernia repair

INTRODUCTION

Inguinal hernia repairs (IHR) are commonly performed by pediatric surgeons in the United States. The operative approach depends on surgeon preference with no definitive prospective studies comparing laparoscopic inguinal hernia repair (LIHR) versus traditional inguinal hernia repair (TIHR). We aim to assess current practice, hypothesizing that laparoscopy is increasingly used for pediatric IHR.

MATERIAL & METHODS

The Children's Hospital Association (CHA) Pediatric Health Information System was queried for IHRs performed between 01/01/2009 and 12/31/2018. Demographics, procedure type, hernia laterality, and cost were obtained. Patients were grouped by procedure type (laparoscopic/traditional).

RESULTS

125,249 IHRs were performed at 32 CHA hospitals during the ten-year study period. 115,782 (92.4%) were TIHR and 9467 (7.6%) LIHR. Use of laparoscopy increased 5-fold from 3% to 15% over the study period. When comparing laparoscopic to traditional IHR groups, there were more females (28.3% vs 12.6%), African-Americans (19.7% vs 14.4%), government-insured (50% vs 45.2%), younger patients (4.2 vs 4.4 years), bilateral IHRs (11.4% vs 7.9%), and higher adjusted total hospital cost ($3,791 vs $2995) in the laparoscopic group (p<0.0001, all comparisons).

CONCLUSIONS

Laparoscopy for pediatric IHR is increasing at CHA hospitals where nearly 1 in 6 children currently undergoes a laparoscopic repair. The long-term outcomes with laparoscopic repair are worthy of future study.

A single institution experience with Laparoscopic Hernia repair in 791 children

INTRODUCTION

There are many described technique to performing laparoscopic inguinal hernia repair in children. We describe our outcomes using a percutaneous internal ring suturing technique.

METHODS

A retrospective review of patients under 18 years old who underwent repair between January 2014 - March 2019 was performed. A percutaneous internal ring suturing technique, involving hydro-dissection of the peritoneum, percutaneous suture passage, and cauterization of the peritoneum in the sac prior to high ligation, was used. p < 0.05 was considered significant during the analysis.

RESULTS

791 patients were included. The median age at operation was 1.9 years (IQR 0.37, 5.82). The median operative time for a unilateral repair was 21 min (IQR 16, 28), while the median time for a bilateral repair was 30.5 min (IQR 23, 41). In total, 3 patients required conversion to an open procedure (0.4%), 4 (0.6%) experienced post-operative bleeding, 9 (1.2%) developed a wound infection, and iatrogenic ascent of testis occurred in 10 (1.3%) patients. Twenty patients (2.5%) developed a recurrent hernia. All but two were re-repaired laparoscopically.

CONCLUSIONS

The use of percutaneous internal ring suturing for laparoscopic repair of inguinal hernias in the pediatric population is safe and effective with a low rate of complications and recurrence.

Laparoscopic percutaneous extraperitoneal closure with peritoneum reinforcement repair for pediatric inguinal hernia: a single-center experience with over 2,000 patients

BACKGROUND

Inguinal hernia is one of the common diseases in infants and children that requires operative treatment. Laparoscopic inguinal hernia repair in children has become an alternative to the open procedure. Laparoscopic percutaneous extraperitoneal closure with peritoneum reinforcement (LPECPR) is a safe and effective approach for pediatric inguinal hernia, and has a lower recurrence. This is a retrospective study to present our experience with children who underwent LPECPR.

METHODS

A total of 2,018 patients with inguinal hernia who underwent LPECPR in our hospital from July, 2011 to December, 2020 were reviewed. The surgical technique is modified on the basis of laparoscopic percutaneous extraperitoneal closure (LPEC) to close extraperitoneally by circuit suturing twice around the internal inguinal ring.

RESULTS

All cases were completed LPECPR without conversion. There were no intraoperative complications. A total of 2,018 patients' laparoscopic procedures were achieved. The mean operative time was 14 and 20 min for unilateral and bilateral operations, respectively. Follow-up to date is 13.4 months (6-36 months), there were no postoperative complications, such as knot reactions, hydrocele formation, testicular atrophy or pain, except 3 recurrences (3/2,018, 0.15%).

CONCLUSIONS

This modified LPECPR technique can acquire lower recurrence rate for repair pediatric inguinal hernia. The midterm safety and efficacy of LPECPR are proven and it can be a routine procedure.

Needlescopic assisted internal ring suturing; a novel application of low-cost home-made instruments for pediatric inguinal hernia repair

BACKGROUND

Congenital inguinal hernia (CIH) is a commonly performed surgical procedure in infants and children. Single port laparoscopic hernia repair using percutaneous internal inguinal ring (IIR) suturing procedure is a widely employed technique for indirect inguinal hernia repair in children. The majority of extracorporeal techniques use extracorporeal knotting and burying the knot subcutaneously. This may result in many drawbacks. The aim of this multicenter study is to introduce a new technique for pediatric inguinal hernia repair using only needles without any laparoscopic instruments.

PATIENTS AND METHODS

This is a multicenter study which was conducted at Pediatric Surgical Departments of Al-Azhar, Mansoura, Alexandria and Tanta Universities during the period from January 2015 to June 2017. 314 patients with CIH underwent Needlescopic Assisted Internal Ring Suturing (NAIRS) after cauterization of the hernia sac at its neck. The main outcome measures were: feasibility, safety of the technique, operative time, recurrence rate, hydrocele and cosmetic results.

RESULTS

A total of 314 patients with CIH were corrected by NAIRS. They were 232 males and 82 females. The mean age was 28.12 ± 1.3 months (range 6-120 months). The mean operative time was 12.6 ± 1.7 min (range 8-15 min) for unilateral cases and 18.6 ± 1.7 min (range 14-20 min) for the bilateral repairs. All cases were completed laparoscopically without major intraoperative complications. No recurrence was detected in this study. No wound complications or umbilical hernias developed. Hydrocele occurred in five males (2.16%), without detection of testicular atrophy or iatrogenic ascent of the testis.

CONCLUSION

This preliminary study showed that NAIRS after cauterization of the neck of the hernia sac in infants and children is safe, feasible, reproducible with excellent cosmetic results.

Algorithm of Laparoscopic Technique in Pediatric Inguinal Hernia: Results from Experience of 10 Years

BACKGROUND

Many laparoscopic techniques have been evolved along years for pediatric inguinal hernia (PIH) with no standardization of technique. No single technique suits all varieties of hernia.

PURPOSE

To propose an algorithm for allocation of PIH to laparoscopic technique based on internal ring (IR) diameter to improve outcomes.

PATIENTS AND METHODS

Along 10 years, 459 cases with unilateral PIH were treated in Tanta University Hospital. In the first 5 years (phase I), 214 cases included then an algorithm for stratification was designed and applied in the second 5-year period (phase II), where 245 cases managed. This algorithm included evaluation of the hernia based on IR diameter as measured by the laparoscope from inside by a piece of suture. When the IR diameter is from 4 to 15 mm, complete sac disconnection is used. When IR diameter lies from 15 to 25 mm a purse string is added. When IR diameter is >2.5 cm or recurrent cases, the interrupted muscular arch repair after sac disconnection is used.

RESULTS

In phase I, 170 boys and 44 girls from 6 to 180 months of age were treated. All cases managed by laparoscopy were 84 herniotomy, 82 by purse string, and 44 by interrupted muscular arch. In phase II, 180 boys and 65 girls from 3 to 180 months of age were included. Eighty were managed by herniotomy, 137 by purse string, and 25 by interrupted muscular arch. Recurrence rate decreased significantly in phase II.

CONCLUSIONS

Application of Tanta algorithm reduces the recurrence rate significantly. The laparoscopic technique should be tailored according to criteria of each group of PIH to get the best outcome and reduced recurrence rate.
