Inguinal Hernia Repair In Children Research Articles

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

BackgroundIn 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. MethodsData 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. Results32 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 ExperienceIn 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. ConclusionsLaparoscopic inguinal hernia repair in children is a versatile and safe procedure that can be carried out with minimal complications and low reoperation rates.Level of Evidence: Level IV

Percutaneous Internal Ring Suturing (PIRS) - The Benefits of Laparoscopic Inguinal Hernia Repair.

IntroductionThe laparoscopic inguinal hernia repair in children using the PIRS technique is a well-established method. However, there are still opinions that this method does not bring more benefits than open surgery.PurposeThe study aims to demonstrate the benefits of laparoscopic technique over conventional, open techniques.Patients and MethodsWe conducted a retrospective study that included children aged 0–18 treated using the PIRS technique in 2008–2016. The control group consisted of patients treated with the traditional, open method of inguinal hernia repair. A total of 276 children were qualified for laparoscopic surgery, and there were 274 patients in the control group. A full laparoscopic procedure was performed on 247 patients. Assessment of the pathology of the internal inguinal ring was done in all patients during the laparoscopic procedure. Intraoperatively 79 children had bilateral inguinal hernia diagnosed, 133 right-sided inguinal herniae, and 57 left-sided inguinal herniae. The occurrence of hernia was not confirmed in 7 children, whereas 53 patients had open contralateral patent processus vaginalis. In a case of contralateral patent processus vaginalis, the repair was performed using the PIRS method.ResultsThe recurrence of the inguinal hernia was observed in 10 children in the laparoscopic group and in 5 cases in control group. The duration of the procedure was noted and compared to open inguinal hernia repair. There was a statistically shorter duration of the laparoscopic method. In the control group, there were 16 patients with a metachronous contralateral inguinal hernia.ConclusionThe laparoscopic inguinal hernia repair was associated with a better assessment of hernia pathology, shorter operative time, and lower risk of contralateral hernia repair.

Ultrasound-guided transverse abdominis plane block, ilioinguinal/iliohypogastric nerve block, and quadratus lumborum block for elective open inguinal hernia repair in children: a randomized controlled trial

Background and objectivesUltrasound-guided ilioinguinal/iliohypogastric (II/IH) nerve blocks and transverse abdominis plane (TAP) blocks are widely used for postoperative analgesia in children undergoing inguinal hernia repair (IHR). Quadratus lumborum block (QLB)...

Comparison of Inguinal Herniotomies with and Without Opening the External Oblique Aponeurosis in Children Above the Age of Two.

Mitchell-Banks technique (MBT), in which inguinal canal is not opened, usually used in inguinal hernia repair in children under 2 years of age. The majority of pediatric surgeons tend to open the inguinal canal while performing inguinal hernia surgery in children over 2 years of age, called as modified Ferguson herniotomy (FH). This study aimed to compare early and late complications of the MBT and FH in over 2 years of age patients who underwent inguinal hernia surgery. We retrospectively reviewed the medical records of all children between 2 and 16 years old who underwent inguinal herniotomy procedure using the MBT and FH between January 2013 and December 2019. Patients were evaluated in terms of demographic data, early and late complications. This study included 834 children. Of these, 379 (44.8%) were operated on by an FH with opening the inguinal canal (Group 1), and 455 (55.2%) by MBT superficially to the external ring (Group 2). There were 68 (17.9%) females and 311 (82.1%) males in group 1, while there were 151 (33.2%) females and 304 (66.8%) males in group 2. Early complications were wound infection (1.1% in the group 1 vs. 1.3% in the group 2, P = 1.00) and scrotal hematoma (1.3% vs. 1.8%, P = 0.89). Late complications included recurrence (1.6% in the group 1 vs. 1.8% in the group 2, P = 0.12), undescended testis (2.1% vs. 0.7%, P = 0.71), testicular atrophy (1.5% vs. 0.4%, P = 0.79), and hydrocele (1.9% vs. 1.8%, P = 0.87). There was no statistically significant difference in terms of early and late complications ratio between two groups. This study showed that inguinal hernia repair performed without opening the inguinal canal in children older than 2 years do not lead to an increase in complications. In this respect, MBT can be used as a simple and safe procedure in older children.

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

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

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

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

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

BackgroundFor 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. MethodsThis 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. Results155 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. ConclusionsLaparoscopic 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.

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

Background/PurposeThe 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). MethodsWe 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. ResultsBoth 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). ConclusionsThe PHELPS technique shows improved results in terms of recurrence and hydrocele as compared to SEAL. Level of EvidenceLevel III Type of studyRetrospective Comparative Study

Comparison of laparoscopic percutaneous internal ring suturing method and open inguinal hernia repair in children under 3 months of age.

Laparoscopic inguinal hernia repair in younger infants has not been completely accepted worldwide. The aim of this study was to evaluate the safety and feasiblity of laparoscopic percutaneous internal ring suturing method in children aged younger than 3 months and compare the recurrence and complication rates with open repair; which may still be mentioned as the gold standard procedure. A total of 387 children underwent inguinal hernia repair in the clinic between 2016 and 2019. One hundred and forty of them were under 3 months old and divided into two groups; children who underwent laparoscopic percutaneous internal ring suturing (Group 1) and open surgery (Group 2). Selection of the surgical method was regardless of weight, sex or any patient characteristics other than surgeon's choice. Operation durations, complications and recurrences were compared between the two groups. A total of 140 patients underwent surgery due to inguinal hernia. Group 1 included 85 and Group 2 included 55 children. There were two recurrences in each group (p> 0.05). Operative durations were shorter in Group 1 for both; unilateral and bilateral repairs (p <0.0001). There were no intraoperative complications in any group. There was one major postoperative complication in Group 2: iatrogenic undescended testis, and none was observed in Group 1. In the laparoscopic group, 47% of the children who were diagnosed to have unilateral hernia were revealed to have bilateral inguinal hernias (n= 31). Laparoscopic percutaneous internal ring suturing method seems favourable in terms of operative time. It also has the advantage of detecting contralateral patent processus vaginalis or asymptomatic contralateral inguinal hernia.

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

BackgroundInguinal 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.MethodsA 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.ResultsAll 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%).ConclusionsThis 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.

Laparoscopic treatment of inguinal hernia in female children – national experience

Background. Although, laparoscopic inguinal hernia repair in children is gaining ground as a safe, feasible, and popular method, still many pediatric surgeons continue to debate its safety, efficacy, and cosmesis in comparison with conventional open repair. Materials and methods. This was a prospective clinical study, that elaborated 98 female children aged 1–14 with clinically diagnosed indirect inguinal hernia. Equal proportions of 49 children were treated via laparoscopic (PIRS) either conventional open repair (OR). Outpatient clinic follow up was performed regardless of the type of the intervention, on the 7th day and 6 weeks after discharge. Results. The mean age of children in PIRS vs. OR group was 5.3±2.7 vs. 5.9±3.3 years. There was no significant differences between the groups related to age (p = 0.4221), weight (p = 0.5482), family history (p = 0.5377), and residency rural/urban (p = 0.3161). The average length of unilateral vs. bilateral PIRS repair (29.5±6.8 vs. 43.6±7.2 min) was significantly shorter than OR (44±4.2 vs. 97±8.1 min) for consequently p = 0.0023 vs. p = 0.00001. The post-operative hospitalization after PIRS repair was 14.1±3.1 hours and was significantly shorter compared to OR – 44±4.2 hours (p = 0.00001). In OR group, 4 (8.2%) children had postoperative nausea compared to none in PIRS group. Significantly bigger cosmetic satisfaction was found in PIRS compared to OM group (p = 0.0001). Conclusion. With due respect to OR as a gold standard, the proven advantages of PIRS are motivation for further improvement of this technique for the purpose of treatment of inguinal hernia of female children.

The Operative Time for Unilateral Inguinal Hernia Repair in Children Performed with Percutaneous Internal Ring Suturing (PIRS) or Open Approach Method.

In this study, we compared the operative time for unilateral inguinal hernia repair in children performed with either an open approach (OA) or the Percutaneous Internal Ring Suturing (PIRS) method. It was a retrospective chart review of all patients ages 0 to 18 who underwent unilateral inguinal hernia repair in the Department of Pediatric Surgery, Urology and Traumatology of the Regional Hospital in Kielce between January 2011 and December 2018. Patients with bilateral hernias or additional problems were excluded. Of 878 patients qualified for the study, 701 were in the OA group and 177 in the PIRS group. Overall, the time needed to complete the procedure was significantly longer for the OA method. The operative time was longer if the hernia was left-sided (p = 0.024). Analysis by gender showed that operative time was generally longer in males. For both genders, surgery was shorter if the PIRS method was used. For males in the PIRS group the operative time was affected by the location of the hernia, and it was longer for a left-sided hernia. The take-home message is that the PIRS procedure is faster than the OA for inguinal hernia repair in children and it might be considered as a preferred method, especially in females.

A single institution experience with Laparoscopic Hernia repair in 791 children

IntroductionThere are many described technique to performing laparoscopic inguinal hernia repair in children. We describe our outcomes using a percutaneous internal ring suturing technique. MethodsA 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. Results791 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. ConclusionsThe 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 Inguinal Hernia Repair in Children: To Cut or Not to Cut is the Question?

Context:Laparoscopic repair of pediatric inguinal hernia is gaining popularity, however there is no consensus about the technique of operation.Aims:The aim of the study was to compare the results and complications of two techniques of laparoscopic pediatric hernia repair.Settings and Design:This retrospective study was conducted at the Department of Pediatric Surgery in All India Institute of Medical Sciences (AIIMS), Jodhpur.Subjects and Methods:All children who underwent laparoscopic inguinal hernia repair at AIIMS, Jodhpur, during the period of September 2016–March 2019 were retrospectively studied. Parameters studied included age, gender, side of hernia, technique used, operating time, complications, and hospital stay. Patients were divided into two groups depending on whether the hernial sac was divided or not divided before taking a purse-string suture.Statistical Analysis Used:Student's t-test and Fischer exact test were used to analyze data.Results:A total of 114 patients were included in the study. The median age was 36.4 months. Hernial sac was divided before suturing in 53 patients, while sac was left intact in 61 patients. The mean follow-up was 11.4 months (range: 4–16). Age, gender, side of hernia, complications, and hospital stay were comparable in both groups. There was a significant difference between the mean operating duration in patients who underwent division of hernia sac compared to patients in whom the sac was not divided before putting purse-string suture (92.5 min [45–150] vs. 65.7 [30–90], respectively, P = 0.0101). Hernia recurrence (3.8% in Group A vs. 1.6% in Group B) was comparable in the two groups.Conclusions:Laparoscopic pediatric hernia repair done with or without dividing the peritoneal sac gives comparable results, however operative duration is less if sac is not divided.

The laparoscopic repair of inguinal hernia in female children in the Republic of North Macedonia

Introduction/Objective. Laparoscopic inguinal hernia repair in children is a minimally invasive method, and with its safety, feasibility, and excellent cosmesis is an acceptable alternative to open repair. Methods. This is a prospective clinical study, with national data of 49 female children aged 1?14 years, treated via laparoscopic approach. Operative time, time to verticalization (normal position in bed, standing/ walking), hospital stay, nausea, pain, and cosmetic effects (size and visibility of the mark) were elaborated. Results. The results revealed that five (10.2%) children had a family history of inguinal hernia. A total of 29 (59.2%) children had hernia located on the right side, 19 (38.8%) on the left side, and one (2%) on both sides. The average diameter of the inguinal opening was 3 ? 2.17 cm. Sixteen children (32.7%) had hidden hernia. The average operation time of the unilateral intervention was 29.5 ? 6.8 minutes, and for bilateral hernias it was 43.6 ? 7.2 minutes. The average length of hospitalization was 14.1 ? 3.1 hours, and the time needed for a full return to a normal position in bed was 2.6 ? 0.6 hours. The average length of the scar in both the right and the left groin region was 2.2 ? 0.4 mm. A total of 46 (93.9%) parents/guardians were satisfied by the esthetic result, while three (6.1%) had no particular opinion regarding this question. Conclusion. The introduction of laparoscopic surgery in the treatment of inguinal hernia is a promising method, which plays an important role as an alternative surgical technique because of the minimal invasiveness of the technique and improved recovery of the children.

Video-assisted percutaneous hernia sac suturing: a new technique of inguinal hernia repair in children

Background. Inguinal hernias are very important problem in pediatric surgery. It appears in 520 cases in every 1000 newborns, approximately 10 times prevalence in males. However, the incidence of inguinal hernia is bigger by 1.52 times in group of premature infants.&#x0D; Materials and methods. In prospective study, that was performed in 20192020, 90 pediatric patients diagnosed inguinal hernia were included. All patients had open herniotomy (Duhamel method), subcutaneous endoscopic-assisted ligation of inguinal hernia using Tuohy needle, or video-assisted percutaneous hernial sac suturing (VIPS).&#x0D; Results. The mean operating time in VIPS group was 13 13.46 min in patients with unilateral inguinal hernia and 20 6.12 min in patients with bilateral variant. In the 6-month follow-up period, any complications or recurrences were not observed. VIPS group included two extremely premature infant with uni- and bilateral inguinal hernia. Minimally invasive herniotomy was performed in 50 weeks post-conceptual age, with unremarkable postoperative period. A difference was found in the operating time between groups of minimally invasive herniotomy and group of Duhamel repair. No difference was found in the operating time of bilateral hernia between all groups.&#x0D; Conclusion. Considered all things, assuming that announced method of video-assisted percutaneous hernial sac ligation to be a perspective minimal invasive way of treatment for inguinal hernia in children is reasonable. However, for final conclusions, further study of this surgical technique, also in a cohort of premature infants, is required, with the possible organization of multicenter clinical trials.

Percutaneous Internal Ring Suturing for the Minimal Invasive Treatment of Pediatric Inguinal Hernia: A 5-Year Single Surgeon Experience.

Percutaneous internal ring suturing (PIRS) is a minimally invasive surgical technique of laparoscopic hernia repair in children under the control of a laparoscope placed in the umbilicus. The aim of this study was to evaluate the management and postoperative outcomes of PIRS for inguinal hernia repair in children. All children who underwent PIRS for an inguinal hernia, between February 2015 and February 2020, were included in the prospective cohort study. The following parameters were recorded: age, gender, body mass index, lateralization of hernia, surgical and anesthesia times, level of pneumoperitoneum, additional trocar introduction, length of hospital stay, and intraoperative or postoperative complications and recurrences were recorded. A total number of 228 PIRS procedures were performed in 188 children [126 (67%) male individuals and 62 (33%) female individuals] with a median age of 4 [interquartile range (IQR), 2 to 6] years and a median follow-up of 46 (IQR, 38 to 52) months. From the total number of hernia repairs there were 99 (52.7%) right, 49 (26.1%) left, and 40 (21.2%) bilateral hernia repairs. Median surgical time was 10 (IQR, 8 to 12) minutes for unilateral and 16 (IQR, 14 to 20) minutes for a bilateral repair. The median hospital stay was 24 (IQR, 8 to 24) hours. Regarding intraoperative complications, only 3 (1.3%) inferior epigastric veins injuries were recorded, without any consequences. During the follow-up period in 3 male children, hydrocele was recorded; in 2 cases, hydrocele resolved spontaneously and 1 required surgical treatment. No cases of other complications including testicular atrophy or recurrence were recorded. In a hands of an experienced pediatric laparoscopic surgeon, PIRS is a simple, safe, and effective technique for inguinal hernia repair in children with excellent outcomes, cosmetic results, and a low incidence of complications and recurrence.

A comparative study examining laparoscopic and open inguinal hernia repair in children: a retrospective study from a single center in China

BackgroundPediatric inguinal hernia (PIH) is a common disease in children. Laparoscopic hernia repair (LHR) has developed rapidly in recent years, but there are still different opinions compared with traditional open hernia repair (OHR). The purpose of this study was to compare the advantages and disadvantages of LHR and OHR in the treatment of pediatric inguinal hernia.MethodsWe performed a retrospective review of all children (< 14 years) who underwent repair of inguinal hernia in the pediatric surgery center of the Affiliated Hospital of Qingdao University from January 2015 to December 2015. We collected the medical records of all the children and analyzed the clinical characteristics, operation-related information and follow-up.ResultsIn the OHR group, 202 cases underwent unilateral inguinal hernia repair, and 43 cases underwent bilateral inguinal hernia repair. In the LHR group, 168 cases underwent unilateral inguinal hernia repair, and 136 cases underwent bilateral inguinal hernia repair. There was a significant difference in the operation time between the two groups, but there were no significant differences in postoperative hospitalization time and incidence of ipsilateral recurrent hernia between the two groups. The incidence rates of metachronous contralateral hernia (MCH) and surgical site infection in LHR group were significantly lower than those in the OHR group.ConclusionOur study shows that compared with OHR, LHR has the advantages of concealed incision, minimal invasiveness, reduced operation time, detection of contralateral patent processus vaginalis, and reduced incidence of MCH. In conclusion, LHR is safe and effective in the treatment of pediatric indirect inguinal hernia.
