[Inguinal hernia in children: easily incarcerated]

Inguinal hernia in children is caused by an incomplete obliteration of the vaginal process during the embryological development. The vaginal process can thus become a hernia sac that often contains bowel and in girls, an ovary. The diagnosis of inguinal hernia is made by history and physical examination. According to current guidelines surgical repair should be performed without delay to avoid incarceration, which gives a high risk of complications, including testicular atrophy and ischemia of vital organs. However, patients are regularly not referred adequately. We present three cases of children who developed complications of a non-repaired inguinal hernia. Additionally, the data of all children with a congenital inguinal hernia, surgically treated from January 2018 until August 2019 show that out of 243 children 13.6% presented acutely with an incarcerated inguinal hernia. Another 6% received a wrong advice from their primary care doctor and was not referred to a (pediatric) surgeon.

Urinary bladder herniation through inguinal ring in a female cat

A 7-month-old spayed female domestic shorthair cat was referred for lethargy, stranguria, and a fluctuant mass of varying size in the right inguinal region. Computed tomographic imaging revealed the urinary bladder partially herniated through the right inguinal canal. Primary herniorrhaphy was performed and re-placement of the urinary bladder was confirmed via laparotomy.

[Pathologies of peritoneo-vaginal canal in pediatric surgery at the teaching hospital Gabriel Touré]

The closure anomalies of the peritoneal-vaginal canal include several clinical entities, which are at the origin of various symptomatology.

OBJECTIVE

To study the anatomo-clinical and therapeutic aspects of pathologies of the peritoneal-vaginal canal.

MATERIALS AND METHOD

This was a prospective study from January 1^st to December 31^st, 2015 carried out in the pediatric surgery department of University Hospital Gabriel Touré. It covered all children aged 0-15 years old with a pathology of the peritoneal-vaginal canal operating in the department during the study period. This study did not include cases that were not operated on or not seen during the study period.

RESULTS

During the study period, 2,699 children were treated in pediatric surgery, of which 150 cases of pathology of the peritoneal-vaginal canal had a hospital frequency of 5.5%. The average age was 3.25 ± 9.63 years. The sex ratio was 14. The reason for consultation was intermittent or permanent inguinal or inguino-scrotal swelling in all children. The pathology was discovered by the parents during the pushing efforts in 46.7%. Inguino-scrotal swelling was found on physical examination in 40% of cases. The right side was reached in 60% of the cases. Hernia accounted for 80.6% of these pathologies. We recorded 31 cases of strangulation and 11 cases of craze. Immediate operative follow-up was simple in 92% of patients. This rate was 96% after 6 months.

CONCLUSION

Pathologies of the peritoneal-vaginal canal are very common in pediatric surgical practice. The first place of these pathologies is occupied by hernia. They preferentially affect male infants.

Irreducible Indirect Inguinal Hernia in Premature Infant with Ectopic Uterus and Bilateral Adnexa

Indirect inguinal hernia is one of the most common congenital anomalies in children, with a reported prevalence of 0.8-4.4%.1 About 15-20% of hernias in female infants contain ovary, and in rare cases a fallopian tube.2 However, only a few cases contain the uterus and both ovaries in the hernia sac.3 The normal anatomy is altered when an ovary is trapped in a hernia sac, and these changes make torsion more likely and increase the risk of infertility. Although an irreducible ovary is not at great risk of compression of its blood supply, in these occurrences, ovarian torsions have been reported in 2%-33%, emphasizing the importance of early surgical repair in irreducible hernias, even in asymptomatic patients.4 The presentation of an asymptomatic palpable movable mass over the labium major always suggests sliding hernia with ovary. To our knowledge, only a few reports of hernia sac containing uterus, fallopian tube, and ovary in a female patient have appeared in the literature. We suggest that sonography be performed routinely in female infants with an inguinal hernia containing a palpable movable mass. We present a rare case of premature female infant with a labial mass containing the uterus, both ovaries, and fallopian tubes.

Mucopolysaccharidosis type II with inguinal hernia

Mucopolysaccharidosis Type II (Hunter syndrome) is a rare X-linked recessive storage disorder caused by deficiency of lysosomal enzyme iduronate-2-sulfatase, causing excess accumulation of glycosaminoglycans in the lysosomes resulting in cellular damage, organ failure and death. Severe subtype develops characteristic clinical features and cognitive impairment early and die in second decade of life. In a resource poor setting, we report a case of Hunter syndrome, severe subtype, based on global development delay, coarse facies, short stature, hepatosplenomegaly and dysostosis multiplex on X-ray with unusual large congenital inguinal hernia. The diagnosis was important because of risk of recurrence of hernia after repair.

Inguinal herniotomy in children: a one year survey at Nepal Medical College Teaching Hospital

This was a prospective study done at Nepal Medical College Teaching Hospital from July 2008 to June 2009 which covers our experience in inguinal herniotomy in children. Our study included 63inguinal hernia repairs in 61 children up to the age of 15 years. Out of 61 patients 2 had bilateral inguinal hernia and 59 had unilateral. Among 59 patients with unilateral hernias, 7 patients had emergency presentation. In children with unilateral hernias, it was found that it is more common at right side and regarding complication it is more common in emergency group. There were 5 recurrences and 5 wound infection among all patients.

Amyand's hernia in premature twins

Amyand's hernia (AH) is the presence of a normal or inflamed vermiform appendix in an inguinal hernia sac. This condition is unusual in neonates and in infants, and it has not been described in premature twins. We present two 32-day-old biovular twins with a right AH, treated with sparing of the appendix and herniotomy. The correct management of AH is discussed via a brief review of the literature.

Traitement par cœlioscopie des hernies inguinales de l'enfant: 212 patients

OBJECTIVES

Laparoscopic treatment of inguinal hernias in children remains controversial. The inguinal approach is the only recommended procedure nowadays. The aim of our series was to precise the results of this technique and its advantages.

POPULATION AND METHODS

We report our preliminary experience in laparoscopy for inguinal hernias in 212 children.

RESULTS

Laparoscopy allowed us to discover 26 controlateral hernias not previously diagnosed, 3 direct hernias with 1 of them associated with a patent process vaginalis, 2 femoral hernias associated with a patent process vaginalis, 1 double pouch hernia and 1 volvulus of a cyst developed from a patent process vaginalis. In case of recurrence after an inguinal approach, laparoscopy seemed to be helpful to evaluate the anatomical lesion. We observed only 1 recurrence.

DISCUSSION

Indications for laparoscopy in case of inguinal hernia in children are reviewed and discussed in the literature. Laparoscopic diagnosis for a precise diagnosis is no more discussed. Various techniques were proposed in case of laparoscopic treatment of inguinal hernias in children: most of surgeons realized only a suture of the sac. We prefer to dissect all the sac in order to avoid any recurrence. Advantages of laparoscopic approach become more obvious after the age of 2 years when the opening of the parietal wall is required in case of an inguinal approach and when local anaesthesia is no more recommended. The opportunity to diagnose a bilateral hernia when non diagnosed before surgery or to discover a femoral or a direct hernia, or in case of recurrence after an inguinal approach, the atraumatic dissection of the vas and spermatic vessels at the level of the internal inguinal ring, are the main advantages for laparoscopy.

[Focusing of inguinal hernia in children]

Abnormal persistence of the processus vaginalis in children predisposes to a complication that is strangulated inguinal hernia. The inguinal hernia is a frequent pathology because global incidence varies from 0,8 to 4,4% for children of any age and reaches about 30% in premature children. Strangulated inguinal hernia is rare (from 1,5 to 8%) and constitutes a surgical emergency. More frequently, reduction following sedation is possible (from 25 to 33%), and normally leads to delayed surgery. Current practice is to operate early in these children, including preterm infants, before any complication arises. This early surgery requires use of regional anaesthetic techniques such as spinal anaesthesia, ileo-inguinal ileohypogastric nerve blocks and caudal anaesthesia. However, although this pathology may appear to be routine commonplace it requires a specialized surgical and anaesthetic approach and specialized environment.

Laparoscopic flip-flap technique versus conventional inguinal hernia repair in children

BACKGROUND AND OBJECTIVES

Inguinal hernia repair is one of the most frequently performed pediatric surgical operations. Several pediatric laparoscopic inguinal hernia repair techniques have been introduced. But debate is unresolved regarding the feasibility of laparoscopy for treating pediatric inguinal hernias.

METHODS

A retrospective cohort study enrolled 33 patients who underwent congenital inguinal hernia repair by either the new laparoscopic flip-flap technique or conventional open repair. Patients were divided into 2 groups according to the type of surgery: Group A included those who underwent the new laparoscopic technique, and Group B included those who underwent conventional open repair.

RESULTS

Group A comprised 15 patients (mean age, 39 months), and group B comprised 18 (mean age, 44 months). Mean operative time was 47.5 minutes for Group A versus 27.5 minutes for Group B. Intraoperative complications for Group A included 1 case (7%) of vas deferens injury, and 3 cases (20%) in which the flaps were torn during suturing. In Group B, no intraoperative complications were encountered. In both groups, the mean postoperative hospital stay was 5.5 hours. Postoperative follow-up of 3 months revealed recurrence in 4 patients in Group A (27%), while there were no recurrences in Group B.

CONCLUSION

Our preliminary experience shows unsatisfactory outcomes with laparoscopic flip-flap hernia repair in children. In spite of advancement in the application of laparoscopy in pediatric surgery, conventional open hernia repair is still the gold standard for children, in our experience. Future studies with more numbers and longterm follow-up should be conducted.

Presence of both testes in an inguinal hernial sac

A unique case with fully developed testes and epididymis on the same side has been presented. The hypothesis to explain such a rare occurrence is a failure of the development of one-sided gubernaculums coupled with intra-abdominal adhesions of both the cords resulting in unilateral descent of both the testes. In females, the Mullerian ducts fuse to form the uterus; such a phenomenon in the case of Wolffian ducts is an impossibility, but fusion of vasa deferens and cords in this case point to such a happening.

Spinal anesthesia in infants with ventriculoperitoneal shunt: report of five cases and review of literature

We describe five cases of children with ventriculoperitoneal shunt who underwent abdominal and perineal procedures under spinal anesthesia. Four of them had been born prematurely, and all had suffered from severe neonatal complications. All of our patients suffered from severe respiratory impairment, that had required mechanical ventilation, and three of them suffered additionally from apnea of prematurity. Four patients had ventriculoperitoneal shunt inserted because of obstructive hydrocephalus and one because of congenital central nervous system anomalies. Two underwent subsequently shunt revision. The benefits of spinal anesthesia in this high-risk population are described. The risks of spinal anesthesia in the presence of a ventricular shunt device, especially infection and dural leakage, are discussed, and the literature about this topic briefly reviewed.

Clonidine added to bupivacaine in neonatal spinal anesthesia: a prospective comparison in 124 preterm and term infants

BACKGROUND

Spinal anesthesia (SA) remains the 'gold standard' in neonatal anesthesia for inguinal herniorrhaphy but its short duration impedes its usefulness. We previously demonstrated that clonidine prolongs neonatal SA without immediate side effects.

METHODS

We conducted a prospective observational study of 124 infants undergoing herniorrhaphy under SA with bupivacaine and clonidine. Two cohorts, term (n = 57) and former preterm (n = 67) infants, were evaluated and compared with regard to episodes of apnea, desaturation, and bradycardia within 24 h of SA.

RESULTS

In both groups, postoperative desaturation episodes were unchanged after SA, compared with the 12 preoperative hours, despite significantly increased apnea (P < 0.003 and <0.011 respectively). Transient bradycardias occurred in former preterm infants (P < 0.014): they spontaneously resolved in all cases. Mean arterial pressure did not vary during the study. Upper sensory level of SA, sedation on entering the postanesthesia care unit (PACU) and duration of stay in the PACU were similar in both groups.

CONCLUSIONS

The clinical significance of short apneas, recovering spontaneously without desaturation, remains debatable. It is concluded that addition of clonidine to neonatal SA results in acceptable side effects. Side effects must be compared with the potential advantages before future recommendations.

A case of brittle bone disease

Brittle bone disease--synonym, osteogenesis imperfecta is a rare genetic disorder of collagen synthesis associated with broad spectrum of musculoskeletal problem, where bones break easily. Recently we got a case of OI, whose name is Babu, 3 days old, full term bay with uneventful home delivery. The baby had multiple fractures in all the extremities with deformities with blue sclera with bilateral inguinal hernia. Other systems were found normal. On 10th day of life he was operated for inguinal hernia with satisfactory postoperative recovery and subsequently he was referred to the orthopedic department for further management.

A case of bilateral inguinal hernia recurrence in infancy: investigations on collagen metabolism

BACKGROUND

Recurrent inguinal hernias in early infancy are rare. We report on a case of a 3-month-old male infant suffering bilateral inguinal hernia recurrence (RINGH). Due to previous observations of an altered collagen metabolism in hernia patients, a severe connective-tissue pathology in the infant was hypothesised.

METHODS

Hernial sac tissue of the infant was analysed and compared to specimens from five children operated upon one-sided primary inguinal hernias (controls). In paraffin-embedded sections, we determined the distribution of collagen types I and III by crosspolarisation microscopy and the expression of matrix metalloproteinase 2 (MMP-2) by immunohistochemistry. In fibroblast cultures, expression of collagen types I and III and of MMP-2 was investigated by RT-PCR (real-time polymerase chain reaction) and zymography. Electron microscopical investigations were performed exemplarily in two fibroblast cultures to compare cell morphology.

RESULTS

No differences in collagen I/III ratios between RINGH and controls were found either on protein or on mRNA level. Immunohistochemical and RT-PCR analysis of MMP-2 showed a lowered expression in the RINGH patient, as compared to controls, whereas the gelatinolytic activity of MMP-2 did not differ between the groups. Electron microscopical investigations showed similar cell arrangement and morphology.

CONCLUSIONS

To conclude, a marked biochemical correlate to a severe connective-tissue pathology in the infant suffering inguinal hernia recurrence could not be found. With regard to the slight differences in the expression of MMP-2, a possible role in the genesis of inguinal hernia recurrence cannot be ruled out.
