Femoral hernia in pediatric population: a diagnostic and surgical challenge

PURPOSE

Femoral hernia (FH) is a rare and often misdiagnosed pathology in pediatric population. The aim of our study was to describe the experience of a Tertiary Center in children with FH, underlying diagnostic and surgical details that could improve its management.

METHODS

A retrospective study of pediatric patients who underwent FH repair from January 2010 to June 2023 at our Institution was performed.

RESULTS

In the analyzed period, 31 patients underwent surgical procedure for FH at our institution, of whom 16 (51.6%) were female. The mean age at time of surgery was 5.8 years (range 0.5-17.1 years). The rate of pre-operative misdiagnosis was 35.5% and open approach was adopted in all cases (16.1% with mesh application). Only two patients (6.4%) experienced surgical complications: one recurrence (repaired six months later) and one post-operative hematoma (treated successfully with conservative method).

CONCLUSION

Due to the high rate of misdiagnosis, the variety of surgical approaches proposed, and the potential for intraoperative complications, FH poses a challenge for pediatric surgeons and urologists, as confirmed by the literature. It is essential to underline the importance of a proper clinical examination in order to correctly diagnose FH, make the best surgical plan for the patient and prevent post-operative complications.

Case Report: An unusual case of wide ileoileal intussusception associated with intestinal volvulus in a 8-months-old infant

Introduction

Midgut volvulus and intussusception are prevalent paediatric abdominal emergencies. To the best of our knowledge, this is the first reported case of a connection between intestinal volvulus and a massive intussusception.

Case report

An 8-month-old male infant was brought to the emergency room with a history of abdominal pain and vomiting for <24 h. On physical examination, the child appeared restless and was found to have a circumferential hard mass of approximately 4 cm in diameter in the epigastric region. Upon admission, laboratory results showed a C-reactive protein level of 0.4 mg/dl, LDH level of 351 U/L, mild leukocytosis with a white blood cell count of 12 × 103 /µl, and 67% neutrophils. A physical exam was significant for abdominal distention, hyperresonance in percussion, and a palpable, painful epigastric mass. The findings of the operation included a dilated and ischemic intestinal loop, approximately 25 cm from the ileocecal valve, twisted upon itself for three turns. After de-rotation, an extensive occluding ileo-ileal invagination with an ischemic intestinal loop was identified, and a length of approximately 55-60 cm of the distal ileum, including the ischemic segment, was resected.

Discussion

This is the first reported case of a connection between intestinal volvulus and a massive intussusception. Currently, only two reported cases describe the connection between volvulus and intussusception, which are insufficient to establish a direct link between the two clinical conditions.

Case Report: The acute appendicitis and incarcerated umbilical hernia: a rare association

Introduction

One of the most prevalent congenital wall abnormalities in children, umbilical hernias are often linked to premature or small-for-gestational-age babies. In cases of intestinal malrotation or if the cecum is very movable, generalized peritonitis may facilitate the imprisonment of these hernias.

Case report

We described a case of a 4-month-old baby who had a prior reducible umbilical hernia with a history of fever, vomiting, poor appetite, and constipation for around 48 h. The patient experienced significant intestinal bloating, vomiting, irreducibility of the umbilical hernia, skin pigmentation, and erythema at the umbilical site within 2 days after hospitalization. When there was no free abdominal air, a direct abdominal x-ray revealed evidence of hydro-gas stasis and various hydro-aerial levels that were pertinent to the ileum. In order to reduce the hernia, the patient had an emergency surgical treatment where the hernia sac was isolated and released from the ileal loop, which was securely attached to a fibrin plate. When the herniary sac was opened, a gangrenous and perforated appendix was found inside. On the seventh postoperative day, the patient was released from the hospital after an uncomplicated postoperative stay.

Conclusion

Our patient's clinical presentation is similar to that of only one other case report involving a 25-day-old male patient. Our case presented with a variant of the clinical symptoms of the previously described umbilical hernia, which became unfixable and strangulated as a result of appendix inflammation. The appendix was discovered inside the hernia sac during surgery.

Case Report: Modified Taulinoplasty: a new technique for minimally invasive repair of pectus excavatum

Introduction

About 95% of congenital chest wall deformities are pectus abnormalities, with pectus excavatum (PE) being the most common. The purpose of this work is to offer a modified Taulinoplasty Technique based on 35 consecutive PE patients' 1-year single-center experience in 2022.

Technique

One minimally invasive procedure for PE is taulinoplasty. In order to prevent invasion of the mediastinum or pleural cavity, it is considered that external traction can be used to raise the sternum. Our experience indicates that the most common surgical consequences of this procedure-which involves creating a submuscular and subcutaneous tunnel to install the metal device-are post-operative seroma and wound dehiscence. We modified the conventional method to achieve more aesthetically pleasing results.

Discussion

Taulinoplasty seems to be a safe technique, easier and more feasible than standard Taulinoplasty, with better outcomes in terms of surgical complications, although further experience is necessary to confirm our preliminary data.

Conservative and operative management of spontaneous pneumothorax in children and adolescents: Are we abusing of CT?

BACKGROUND

No age-specific pediatric guidelines exist for the management of spontaneous pneumothorax (SP) in children and adolescents. Treatment remains heterogeneous and center dependent. The role of computed tomography (CT) has yet to be defined.

AIMS

Review the management of SP in children and adolescents, with emphasis on conservative management and role of CT.

METHODS

Retrospective analysis of 61 consecutive patients with SP at single tertiary center. Clinical, radiological, surgical data, follow-up, and outcomes were revised.

RESULTS

First-line management was conservative for 32 (53%) patients and operative for 29 (47%). Asymptomatic/paucisymptomatic patients managed conservatively experienced less first-line treatment failure. Furthermore, the patients needing at least a chest drain or surgery during the follow-up were significantly lower in the conservative group. Conservative and operative patients showed no significant differences regarding ipsilateral recurrences or contralateral occurrences. Of the 61 overall CTs performed, 14 (23%) had an impact on management. Forty-three (70%) patients had at least a CT, in 22 (51%) the CT was positive for blebs. For 10 of these patients (45%) the presence of blebs had an impact on management. Patients with and without blebs showed no differences regarding ipsilateral recurrence, contralateral occurrences, or the need for at least a chest drain or surgery during the follow-up.

CONCLUSIONS

First-line conservative management had a significantly shorter hospitalization and better outcome, with a similar incidence of recurrences. The presence of blebs at CT does not predict the risk of recurrence. The CT scan should be reserved for a small number of selected patients who have post-VATS refractory or recurrent pneumothorax.

The Intraperitoneal Use of Cephazolin: A Novelty in the Prevention of Intra-abdominal Abscess after Laparoscopic Appendectomy in Children

BACKGROUND

Laparoscopic appendectomy followed by postoperative intravenous (IV) antibiotics is the standard of care for acute appendicitis and postoperative prevention of intra-abdominal abscesses. The aim of or study was to determine if intraperitoneal irrigation with antibiotics could help prevent intra-abdominal abscess formation after laparoscopic appendectomy for complicated appendicitis in pediatric patients.

METHODS

A retrospective study was conducted on consecutive pediatric patients with acute appendicitis who had appendectomy in our Pediatric Surgery Department between August 2020 and February 2022. We compared two groups with similar age and symptoms. The first group (A) was treated with the normal standard of care, i.e., laparoscopic appendectomy and postoperative IV antibiotic therapy. For the second group (B) intraperitoneal cefazoline irrigation was added at the end of the laparoscopic procedure. Postoperative intra-abdominal abscess was diagnosed with ultrasound examination, performed after clinical suspicion/abnormal blood test results.

RESULTS

One hundred sixty patients (males:females 109:51; median age 10.5 years [range 3-17 years]) who had laparosopic appendectomy for complicated appendicitis were included, 82 in group A and 78 in group B. In the first 7 days after surgery, 18 patients in group and 5 in group B developed an intra-abdominal abscess (p < 0.005). Drains were positioned in 38 patients in group A vs. 9 in group B. One patient in group A had a different complication which was infection of the surgical incision.

CONCLUSIONS

Intraperitoneal cefazoline irrigation at the end of the laparoscopic appendectomy in pediatric patients significantly reduces the formation of intra-abdominal abscesses.

Aggressive approach for spontaneous pneumothorax treatment in children with Marfan syndrome?

Background and objectives

Marfan syndrome (MS) is a systemic disease of connective tissues consisting of a variable combination of anomalies. These patients have an increased risk of spontaneous pneumothorax (SP). However, there is a scarcity of pediatric literature on management, and no specific guidelines exist. Our aim was to analyze the management of spontaneous pneumothorax in children and adolescents with Marfan syndrome, comparing syndromic and non-syndromic patients.

Methods

Retrospective analysis of pediatric patients (18 years) with SP diagnosed at our tertiary pediatric hospital (January 10-June 22), with special emphasis on diagnosis, treatment, and follow-up (FU).

Results

Sixty-six patients with SP were identified, with nine (13%) having MS. In terms of baseline, there were no significant differences between the groups (age, sex, asthma, symptoms, and side, first-line treatment and hospitalization length). Overall, Marfan patients had significantly more first-line treatment failures requiring additional surgery, as well as more contralateral occurrences and the need for surgery/chest drain during the follow-up. Instead, conservative management resulted in significantly more ipsilateral recurrences and the need for surgery/chest drain in Marfan patients than controls during the follow-up.

Conclusions

Treatment failure, contralateral occurrence, ipsilateral recurrence, and the need for surgery/chest drain during follow-up make management of patients with Marfan syndrome and spontaneous pneumothorax more difficult. In patients with a diagnosed MS a more aggressive first-line management should be considered, bearing in mind the higher risks of this population.

Benefits of using digital thoracic drainage systems for post-operative treatment in pediatric populations: personal experience and review of literature

Introduction

The digital chest drainage monitoring system (Medela Thopaz+), unlike analogical systems, reliably regulates the pressure applied to the patient's chest and digitally and silently monitors critical therapeutic indicators (volume of fluid and/or drained air). Its use in adulthood has been widely described, but there is still little experience in the pediatric field. The aim of this study is to test this new device in the pediatric population.

Materials and methods

We conducted a retrospective study of 160 patients undergoing chest surgery at our Hospital. These patients were divided into 82 treated with the Thopaz system in the period from January 2021 to April 2023 and 78 in whom Pleurevac, had been used in the time period from January 2020 to April 2023.

Results

The average age of patients was 10.45 years (range: 3.1-17.2) for the Thopaz Group and 10.71 years for Pleurevac Group. The groups were homogeneus also by weight and type of intervention. The device was held in place for 10.64 days (mean) for Thopaz Group, compared to 16.87 days (mean) for Pleurevac Group (p < 0.05). The median number of postoperative x-rays before the closure of the chest tube was 4.29 in the digital drainage group compared to 8.41 in the traditional draining group (p < 0.05).

Conclusions

The digital chest monitoring device provides objective measurement, allows for rapid patient mobilization (with good pain control and increased compliance). In addition, the use of Thopaz in the paediatric population seems to be safe (there is no statistically significant difference in terms of complications such as prolonged air leaks and pneumothorax after the chest tube closure) and potentially beneficial.

Case report: A simple and reliable approach for progressive internal distraction of the sternum for Jeune syndrome (asphyxiating thoracic dystrophy): preliminary experience and literature review of surgical techniques

Background

Described for the first time in 1954, Jeune syndrome (JS), often called asphyxiating thoracic dystrophy, is a congenital musculoskeletal disease characterized by short ribs, a narrow thorax, and small limbs. In this study, we analyzed and presented our preliminary experience with a device for progressive internal distraction of the sternum (PIDS) in patients with symptomatic JS. In addition, we reviewed the contemporary English literature on existing surgical techniques for treating children with congenital JS.

Material and methods

A retrospective analysis of pediatric patients (<18 years old) treated for symptomatic JS at our tertiary center between 2017 and 2023 was performed.

Results

We presented two patients with JS who underwent surgery using an internal sternal distractor, a Zurich II Micro Zurich Modular Distractor, placed at the corpus of the sternum among the divided halves.

Conclusions

We obtained promising results regarding the safety and effectiveness of this less-invasive device for PIDS in patients with symptomatic JS. Further studies on long-term outcomes are needed to validate these findings.

Vascular Access in Pediatric Oncology and Hematology: State of the Art

Management and successful use of vascular access are critical issues in pediatric patients affected by malignancies. Prolonged course of disease, complex and various treatment protocols require long-lasting vascular access providing adequate tools to administrate those therapies and to collect routine blood sampling without painful and repeated venipuncture. For these reasons, central venous catheters are currently an important component in pediatric onco-hematological care, with a direct influence on outcome. Indeed, there are peculiar issues (techniques of insertion, management, complications etc.) which must be well-known in order to improve the outcome and the quality of life of children with cancer.

Unilateral vasectomy for intractable epididiymo-orchitis in patients with anorectal malformation

BACKGROUND

Male patients treated for anorectal malformations (ARM) and recto-urethral fistula (RUF) tend to develop recurrent epididymo-orchitis (EO) which occurs approximately in 20% of all them. The optimal management of this condition is unclear because of the extreme its rarity and the unavailability of detailed analysis in literature. To date the majority of this patients benefits from medical treatment and symptoms reduce over time but few data have been published in literature about management of patients with intractable EO.

OBJECTIVE

To describe the efficacy of unilateral vasectomy in patients operated on for anorectal malformations with RUF and affected by intractable EO.

STUDY DESIGN

We present five patients who met the criteria for intractable EO, and followed at our centre four of whom have undergone unilateral vasectomy.

RESULTS

The first episode of EO presented at 42,00 mos ±29.39. Initially, patients were all managed with analgesics and antibiotics. For the failure of therapy, five patients were all offered unilateral vasectomy but only four families accepted procedure. Surgical treatment was performed as a day case without complications. Postoperative follow up was 88,50 mos ±68.36. Prompt and durable resolution of symptoms was observed.

DISCUSSION

The long-term effects of recurrent EO in ARM are often underestimated. Prompt and appropriate intervention should prevent this undesirable sequela. Unfortunately, the optimal management of this complication is unclear, partly because of its extreme rarity. The established management needs to follow the route of correcting underlying anomalies and providing long-term analgesic and antibiotics but this may have undesired side effects. We therefore offered families vasectomy for complete symptom resolution and/or drug withdrawal. Vasectomy, as a form of treatment for, can be justified if it can prevent pain, infection and destruction of the testes. Early vasectomy may save enough functional testis tissue.

CONCLUSION

To date, the only available treatment to achieve definitive resolution of symptoms in intractable unilateral EO is vasectomy. Long-term effects of such procedure on fertility are unknown. The treatment of recurrent EO in cases without site predilection remains a matter of contention.

Appendicitis in COVID19 Pandemic Era. Early experience of an International Referral Center of Pediatric Surgery

AIM

We describe treatments of acute appendicitis at "Bambino Gesù" Children's Hospital during the peak of the Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) pandemic in Italy.

MATERIAL AND METHODS

From March 1st to May 31st, all suspected appendicitis admitted to hospital entered this study. Following Institutional COVID19-protocol, between March 1st-21st, only patients with respiratory symptoms and/or history of recent travel to risk areas received nasopharyngeal swab. From March 22nd to May 31st, protocol was adapted to worsening epidemic conditions and a pre-triage area has been arranged to accommodate all patients undergoing the swab.

RESULTS

14 out of 53 patients were hospitalized between march 1st-21st, 39 from march 22nd to may 31st. swab was performed in 2 patient of first group and in all of second.

DISCUSSION

During the study period, no covid19-contagion occurred in hospital staff by covid19-patients.

CONCLUSION

Our covid19-protocol protected staff and patients allowing the maintenance of our standard of treatment.

KEY WORDS

Appendicitis, Children, Covid19, Sars-cov-2.

Electrocautery only for hyoid bone removal in pediatric thyroglossal duct cyst excision

AIM

Surgical excision of hyoid bone is the mainstay of thyroglossal duct cyst removal, to prevent recurrences. Bone excision by cut - bone forceps may prove inaccurate and somewhat dangerous. Therefore, use of alternative methods has been advocated.

MATERIAL AND METHODS

The proposal of the study is to cut the body of the hyoid bone with the only electric scalpel. Surgical casenotes of 57 pediatric patients operated by our Institution with modified Sistrunk technique and complete dissection of the entire body of hyoid bone and its removal at the cartilage junction with lateral horn with monopolar cauterization were reviewed.

RESULTS

The population of our study had a mean age of 59.86 ± 29.57 months; 6/57 patients (10.5%) were under 2 years of age. Mean follow up was 55,04 ± 29,08 months ranging 2 to 115 months. In any patients post-operative bleeding was observed. Mean surgical time was 57,02 ± 11,77 minutes ranging from 35 to 125 minutes; 6 cases required postoperative drain. In 3 patients an immediate local edema was observed and in another one a partial wound dehiscence occurred, no late complications were observed. Cyst-recurrence requiring re-do surgery occurred in 5 patients (8.8%).

CONCLUSIONS

The complete hyoid bone section with electric scalpel only ensures the ideal access to the posterior hyoid space and allows a greater and more symmetrical access to the proximal portion of thyroglossal duct in children with still negligible complication and recurrence rate.

KEY WORDS

Modified Sistrunk technique, Sistrunk procedure, Thyroglossal duct cyst.

Gait analysis in bladder exstrophy patients with and without pelvic osteotomy: a controlled experimental study

BACKGROUND

The role of bony pelvic anomalies in bladder exstrophy is long established and has generated many papers addressing walking problems. Biomechanical studies and kinematic gait analysis were performed on very young children.

AIM

A direct kinetic gait evaluation has never been performed, nor has the effect of pelvis dimorphism on the upper body been studied.

DESIGN

Controlled experimental study.

SETTING

Outpatients were studied at the time of periodic follow up.

POPULATION

Nineteen patients with bladder exstrophy, age 14±8 years, and twenty-five healthy control participants, age 15±8 years, were enrolled in the present gait analysis study.

METHODS

Clinical evaluation and standard gait analysis were performed.

RESULTS

Gait analysis deviations between exstrophy patients and controls and between patients that received pelvic osteotomy (OT--6 patients) and those that did not (no-OT--13 patients) were analyzed. Bladder exstrophy significantly affects kinematics and kinetics of trunk, spine, pelvis, knee and foot; in particular: in OT, trunk retroversion, pelvic retroversion and rotation, hip adduction angle and moment, knee flexion and its maximum power during loading response increased, whereas in no-OT, spine angle, pelvic posterior tilt, hip extension, and the external rotation of the foot progression angle increased. All the kinetics parameters analyzed in the study showed lower values in the patient group than in controls.

CONCLUSION

. Walking in patients with bladder exstrophy is accomplished by retroversion of the pelvis and deviations mainly in the spine angle in no-OT and in knee flexion in OT.

CLINICAL REHABILITATION IMPACT

Gait analysis was shown to be an effective tool for the detection of walking deviations that should be identified early, prompting rehabilitative treatment in order to prevent spine and knee diseases.

Penile repair in patients with epispadias-exstrophy complex-can we prevent resultant hypospadias?

PURPOSE

Male genitalia reconstruction in patients with exstrophy-epispadias complex often leads to secondary hypospadias, thus requiring additional surgery and resulting in possible complications. We describe a technique of male epispadias repair to prevent resultant hypospadias.

MATERIALS AND METHODS

The complete penile disassembly technique is modified by multiple Z-plasties, which enable creation of a funnel-like bladder neck and urethral plate lengthening. A total of 29 patients 2 months to 12 years old presenting with pure epispadias and bladder exstrophy were treated with this technique between 2004 and 2011. These patients were compared to 19 patients 1 day to 11 years old with exstrophy-epispadias treated with the standard penile disassembly technique between 2000 and 2004.

RESULTS

Outcome measures were urethral orifice position, penile length and complications. There was no statistically significant difference between the 2 groups regarding penile length or complications. In the study group the urethra reached the tip of the glans in all patients, whereas the creation of intentional hypospadias was necessary in 6 patients (31.5%) in the control group (p <0.05).

CONCLUSIONS

The modified technique was effective in obtaining appropriate meatal location without decreasing the penile length. The complication rate was not changed. Creation of resultant hypospadias at genitalia reconstruction in male epispadias should strongly be prevented.
