Laparoscopic Treatment of Inguinal Ovarian Hernia in Female Infants and Children: Standardizing the Technique

The clinical value of ultrasound in assessing ovarian strangulation in female infants and toddlers with ovarian hernia

Objective

To explore the clinical value of ultrasound examination in evaluating the presence of ovarian torsion in female infants with inguinal ovarian hernia.

Methods

We conducted a retrospective analysis of 91 cases of ovarian hernia diagnosed by ultrasonography at our institution. Among them, 6 cases were identified as ovarian strangulation, while 85 cases were classified as non-ovarian strangulation. All cases underwent high-frequency ultrasound examination. We analyzed whether there were differences in the associated factors between the two groups and compared the disparities in the urgency of surgery between the two groups.

Results

Significant differences were observed between the ovarian strangulation group and the non- strangulation group in terms of ovarian volume, ovarian blood flow, and the presence of incarceration. The need for emergency surgery was significantly associated with the presence of incarceration and ovarian torsion.

Conclusion

Ultrasound has good clinical value in diagnosing ovarian hernia and determining the presence of ovarian strangulation. It can assist clinical physicians in determining the timing of surgery for children with ovarian hernia.

Surgical Management of Pediatric Inguinal Hernia: A Systematic Review and Guideline from the European Pediatric Surgeons' Association Evidence and Guideline Committee

INTRODUCTION

 Inguinal hernia repair represents the most common operation in childhood; however, consensus about the optimal management is lacking. Hence, recommendations for clinical practice are needed. This study assesses the available evidence and compiles recommendations on pediatric inguinal hernia.

MATERIALS AND METHODS

 The European Pediatric Surgeons' Association Evidence and Guideline Committee addressed six questions on pediatric inguinal hernia repair with the following topics: (1) open versus laparoscopic repair, (2) extraperitoneal versus transperitoneal repair, (3) contralateral exploration, (4) surgical timing, (5) anesthesia technique in preterm infants, and (6) operation urgency in girls with irreducible ovarian hernia. Systematic literature searches were performed using PubMed, MEDLINE, Embase (Ovid), and The Cochrane Library. Reviews and meta-analyses were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement.

RESULTS

 Seventy-two out of 5,173 articles were included, 27 in the meta-analyses. Laparoscopic repair shortens bilateral operation time compared with open repair. In preterm infants, hernia repair after neonatal intensive care unit (NICU)/hospital discharge is associated with less respiratory difficulties and recurrences, regional anesthesia is associated with a decrease of postoperative apnea and pain. The review regarding operation urgency for irreducible ovarian hernia gained insufficient evidence of low quality.

CONCLUSION

 Laparoscopic repair may be beneficial for children with bilateral hernia and preterm infants may benefit using regional anesthesia and postponing surgery. However, no definite superiority was found and available evidence was of moderate-to-low quality. Evidence for other topics was less conclusive. For the optimal management of inguinal hernia repair, a tailored approach is recommended taking into account the local facilities, resources, and expertise of the medical team involved.

Single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) for inguinal hernia with prolapsed ovary

BACKGROUND

Most studies reporting the outcomes of laparoscopic ovarian prolapsed hernia operations with large sample sizes are based on intracorporeal closure, while studies on extraperitoneal closure have limited sample sizes. We proactively used the single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) technique and obtained favorable outcomes, which we report in this paper.

METHODS

We retrospectively reviewed patients who had undergone laparoscopic surgery for inguinal hernia at our institution. They were retrospectively classified into two groups based on the pre- or intraoperative diagnosis of hernia with a prolapsed ovary, namely the prolapse group and the non-prolapse group, respectively. The data were statistically analyzed and p < 0.05 was considered statistically significant.

RESULTS

A total of 771 subjects underwent SILPEC during the study period, including 400 girls. Among them, 63 girls were diagnosed with an ovarian prolapsed hernia. SILPEC was successfully performed through a single port in all cases, with a single exception, in whom the forceps was inserted directly through the right lower quadrant to pull up the ovary. The duration of surgery in the prolapse group was not higher than that in the non-prolapse group. During the SILPEC surgery, the ovaries were successfully reverted into the abdominal cavity by external compression of the inguinal area alone in 38 of the 63 patients. In the remaining 25 cases, the ovaries were reverted into the abdominal cavity by external compression of the inguinal area and traction of the round ligament with forceps. None of these cases failed to return to the ovaries.

CONCLUSION

Our study results indicate that SILPEC may be performed safely for the treatment of ovarian prolapsed inguinal hernia. Since the ovary and fallopian tube are close to the internal inguinal ring due to the short round ligament, the procedure requires careful suturing with traction of the round ligament.

Optimizing the Working Space for Single-Port Laparoscopic Totally Extraperitoneal Closure of Inguinal Hernia with TPV Protocol in Infants and Young Children

Purpose: To evaluate the outcomes of single-port laparoscopic internal ring closure of inguinal hernia, optimized according to TPV (tilt, pad, and void) protocol, in infants and young children. Methods: From August 2018 to March 2021, a prospective cohort study was conducted including 400 patients younger than 3 years with either left- or right-side inguinal hernia treated with single-port laparoscopic totally extraperitoneal (TEP) closure of the internal ring using a two-hooked core needle apparatus. Patients whose hospitalization ID ended with an odd number were included in group A (n = 200). They were surgically treated with single-port laparoscopy optimized according to TPV protocol, in which the operating table was placed at a 30° head-down tilt position (tilt), the hip was padded by 4-5 cm (pad), and the bladder was voided (void). The remaining patients in group B (n = 200) were conventionally treated with single-port laparoscopic TEP closure of the internal ring. Success rate of surgery, surgery duration, and postoperative complications of two groups were compared. Results: A significantly higher success rate of surgery was detected in group A than in group B (198/200 versus 182/200, P < .05). Regardless of unilateral or bilateral inguinal hernia, surgery duration was significantly shorter in group A than in group B (unilateral inguinal hernia, 14.38 ± 2.85 minutes versus 21.17 ± 4.47 minutes; bilateral inguinal hernia, 20.73 ± 4.58 minutes versus 28.99 ± 4.12 minutes, both P < .05). In addition, the incidence of postoperative complications was significantly lower in group A (1/200 versus 8/200). Conclusions: TPV protocol to optimize working space for single-port laparoscopic TEP closure of inguinal hernia can increase the success rate, shorten surgery duration, and decrease the incidence of postoperative complications.

Single Incision Laparoscopic Percutaneous Extraperitoneal Closure of Internal Ring for Incarcerated Inguinal Hernia in Children: A Single Center Experience with 104 Cases

Introduction: The aim of this report is to present our technique and outcomes of single incision laparoscopic percutaneous extraperitoneal closure of internal ring (SILPEC) for incarcerated inguinal hernia (IIH) in children. Patients and Methods: The medical records of all children undergoing emergency SILPEC for IIH after unsuccessful attempted manual reduction between June 2016 and September 2020 at our center were reviewed. For SILPEC, two trocars 3.5-6 mm were placed through a single umbilical incision. A 17G epidural needle and a small wire-lasso were used for extraperitoneal closure of the internal ring. Results: From a total of 2904 consecutive patients with inguinal hernia (IH) undergoing SILPEC, 104 patients (3.6%) had IIH. There were 84 boys and 20 girls with a median age of 18.5 months (ranged 1 month to 11 years). At the time of surgery under general anesthesia IIH was found to be spontaneously reduced in 26.9%; the hernia contents were bowel in 52.9%, great omentum in 13.5%, and ovary in 6.7% of the patients. All hernias were successfully reduced without additional ports or conversion to open surgery. Patent contralateral processus vaginalis (PCPV) was detected intraoperatively in 44.2% of the cases. The median operative time was 24 minutes for unilateral and 30 minutes for bilateral procedures. The median postoperative stay was 1 day. At a median follow-up of 28 months, there was no case of hydrocele, testicular atrophy, or iatrogenic cryptorchism. The postoperative cosmesis was excellent as all patients were virtually scarless. Recurrence occurred in 1.9% with no significant difference (P = .669) compared to the 1.4% recurrence rate of the 2800 patients with ordinary IH undergoing elective SILPEC during the same study period. Conclusions: SILPEC for IIH in children is feasible, safe, with excellent postoperative cosmesis, and no significant difference in hernia recurrence between emergency SILPEC for IIH and elective SILPEC for ordinary IH.

Needlescopic Disconnection and Peritoneal Closure for Pediatric Inguinal Hernia Repair: A Novel Technique

BACKGROUND

There are many laparoscopic techniques for pediatric congenital inguinal hernia repair. Needlescopic surgery was introduced recently in pediatric patients aiming at getting excellent cosmetic outcomes.

PURPOSE

The aim of this study was to describe a novel technique for needlescopic inguinal hernia repair in children.

PATIENTS AND METHODS

Needlescopic division of the hernial sac was carried out on 369 children in 6 pediatric tertiary centers during the period from August 2016 to May 2019. All hernias were repaired by a novel needlescopic procedure that replicates all the steps of the open herniotomy.

RESULTS

A total of 369 patients with 410 hernias were included in this study. They were 232 (62.9%) males and 137 (37.1%) females, with a mean age of 3.58±1.26 (range=2 to 8 y) and mean internal inguinal ring diameter was 13.65±3.85 mm (range=8 to 20 mm). The mean operative time was 23.36±4.67 minutes for bilateral and 14.28±2.98 minutes for unilateral cases. All cases were completed without conversion to conventional laparoscopy. All cases were followed up for a mean of 19.6±3.2 months. None of our patients developed recurrence or testicular atrophy and the scars were nearly invisible 3 months postoperatively.

CONCLUSIONS

Needlescopic pediatric inguinal hernia repair using disconnection of the hernia sac at internal inguinal ring with purse-string suture closure of peritoneum is feasible and safe with no recurrence and with outstanding cosmetic results.

Management of Postoperative Complications Following Common Pediatric Operations

This review discusses complications unique to pediatric surgical populations. Here the authors focus primarily on five of the most common procedures performed in children: appendectomy, central venous catheterization, pyloromyotomy, gastrostomy, and inguinal/umbilical hernia repair.

Ultrasound-guided pediatric inguinal hernia repair

PURPOSE

Inguinal hernias are amongst the most common surgical conditions in children. Typically, these repairs are performed through an open or laparoscopic approach, using a high ligation of the hernia sac. The use of ultrasound has been described in identifying and evaluating hernia contents in children. Our goal was to determine if ultrasound guidance could be used to perform a high ligation of the hernia sac in pediatric patients.

METHODS

Following IRB approval, a retrospective review of all female patients at a single center undergoing ultrasound guided inguinal hernia repair between 2017 and 2018 was performed. Pre-operative characteristics, intra-operative outcomes, and post-operative outcomes were all evaluated. Laparoscopy was used to evaluate the repair and evaluate for a contralateral hernia. Male patients did not undergo ultrasound inguinal hernia repair to avoid damage to the vas deferens and vessels.

RESULTS

A total of 10 patients with 13 hernias total were found during the study period. A total of one patient was converted to a laparoscopic repair. No patients were found to have an inappropriate repair or a missed contralateral hernia, and there were no vascular injuries or injuries to surrounding structures. No patients had a hernia recurrence during the study period.

CONCLUSION

This study demonstrates the safety and feasibility of ultrasound guided inguinal hernia repairs in female pediatric patients. Further study is needed to compare these repairs to existing techniques, evaluate for recurrences over time, and evaluate if these repairs can be performed without general anesthetic in some patients.

Optimal Viewing Direction of the Oblique Laparoscope in Single-Incision Laparoscopic Percutaneous Extraperitoneal Closure for Inguinal Hernia

Background: It is difficult for novice surgeons to manipulate the oblique laparoscope in single-incision laparoscopic percutaneous extraperitoneal closure (SILPEC) for inguinal hernia because of collisions between the instruments. To standardize manipulation of the laparoscope, we studied the viewing direction of the oblique laparoscope, and assessed the optimal manipulation of the laparoscope to avoid collisions. Methods: A retrospective chart review was performed on patients who underwent SILPEC between April 2016 and April 2017. The viewing direction of the 30° oblique laparoscope was measured according to the location of the field stop pointer. Patients were divided into three groups according to the viewing direction at the beginning of the procedure: the inside viewing direction was from -90° to -11°, upward viewing direction was from -10° to 10°, and outside viewing direction was from 11° to 90°. The length of the procedure, viewing direction at the end, and the percentage of cases in which there was a change in viewing direction during the procedure were compared. Results: Ninety-eight cases of SILPEC were performed during the study period. The percentage of patients with a change in category of viewing direction in the inside, upward, and outside groups was 35%, 21%, and 11%, respectively, showing a significant difference among the three groups. Conclusions: Setting the initial viewing direction to the outside can reduce correction of the viewing direction during SILPEC. Because the intersection angle between the outside-viewing laparoscope and forceps is close to a right angle, this might reduce collisions.

Inguinal hernia in girls: A retrospective analysis of over 1000 patients

BACKGROUND

In girls with inguinal hernia, timing of surgical repair to prevent ovarian strangulation and screening for Androgen Insensitivity Syndrome (AIS) remain controversial. This study assesses the incidence of ovarian strangulation and AIS, and its associated risk factors.

METHODS

Electronic patient records were used to study girls aged 0-15 years who underwent inguinal hernia repair between 2000 and 2017. Patients with incomplete data were excluded. Risk factors were identified using logistic regression.

RESULTS

This study includes 1084 girls (median (IQR) age: 133.5 (14-281) weeks) who underwent 1132 hernia repairs (1015 unilateral, 117 bilateral) within a median (IQR) time interval of 12 (6-23) days following diagnosis. Hernia sac intraoperatively contained ovary in 235 (21.7%) patients, ovary was strangulated in 14 (6%). Risk factors for ovarian strangulation were younger gestational age (OR 0.49), higher birthweight (OR 32.18), and first presentation at the emergency department (OR 13.07). However data were partly missing. Ectopic testis was found in seven (0.6%) patients. Metachronous contralateral inguinal hernia and ipsilateral recurrence developed in 6.1% and 0.3%, respectively.

CONCLUSIONS

Ovarian hernia was diagnosed in 21.7%, and ovary was strangulated in 6%. No definite conclusions can be drawn regarding risk factors for strangulation and timing of surgery in girls with irreducible ovarian hernia.
