Long-term cosmetic outcomes of the slit-slide procedure for umbilical hernia repair in children

PURPOSE

To assess the long-term cosmetic outcomes of the "slit-slide procedure", designed to provide a more natural appearance for umbilical hernia repair, as perceived by the patients and their parents.

METHODS

A total of 149 patients with umbilical hernia underwent the slit-slide procedure at our hospital. The slit-slide procedure allows for the creation of an umbilicus with a more natural and integrated appearance. The patient satisfaction survey questionnaire was mailed to the families (n = 139), and there were 74 (53.2%) respondents. A questionnaire survey on postoperative appearance was also distributed to pediatric surgeons.

RESULTS

The median age at the time of operation was 2.5 years (range, 2 months to 14 years) and the average median age at the time of answering the questionnaire was 6.25 years old (range, 2.5-14.8 years). The average median period of observation was 3.2 years (range, 4 months to 8.97 years). Most patients (89.2%) and parents (93.2%) were satisfied with the appearance of the umbilicus. Twenty-seven patients reported improved satisfaction after surgery (36.2%). Surgeons tended to score the elongated-oval shape highly; however, there was no difference in satisfaction among the shapes.

CONCLUSION

The slit-slide procedure is not only effective and safe, but it achieves a satisfactory aesthetic outcome.

A case series of successfully managing exomphalos major with awake graduated compression dressing and early enteral feeding

INTRODUCTION

Exomphalos anomaly is defined as the herniation of abdominal viscera into the base of the umbilical cord, with only a membranous sac covering these contents. It has an incidence of approximately 1 in 4000-6000 births. Management of exomphalos major (EM) remains controversial and limited, with very few studies to guide decision-making.

METHOD

This is a case series of four neonates with EM treated at a tertiary paediatric referral centre between 2018 and 2021 with a gradual compression dressing technique.

RESULTS

Four neonates were diagnosed with EM. The average gestational age was 38 + 5 (range 38 + 2 - 39 + 2), and the average birth weight was 3.1 kg (range 2.56 - 3.49 kg). The defect size ranged between 5 and 7 cm. All patients were commenced on gradual compression dressing between days 1 and 3 of life. Dressings were applied at the bedside in the general neonatal ward. The average time taken to reach full feeds was 1 week; only one patient required parenteral nutrition. Three underwent surgical repair at two and 16 weeks of age; one had delayed repair at the age of 1 year because of the COVID-19 pandemic. None required patch repair. None required prolonged ventilation after repair.

CONCLUSION

This case series describes a successful compression dressing technique that reduces sac content without the need for general anaesthetic or respiratory compromise, whereby simultaneous enteral feeding is tolerated.

Septic Shock After Endoscopic Sleeve Gastroplasty: A Post-procedural Complication?

BACKGROUND

ESG is a safe and effective technique in the obesity management, usually indicated in class I and II obesity. It is also an acceptable treatment in patients with class III obesity who have high surgical risk or refuse surgery. This procedure results in a significant weight loss and important improvement in metabolic comorbidities. Nevertheless, there are several procedure-related complications. Few cases of gastric perforation following ESG have been reported. We present a case of septic shock after ESG with preoperative diagnostic uncertainties.

METHODS

We present the case of a 54-year-old male with a BMI of 43.6 kg/m2 who underwent ESG 7 days before in an external center. The patient came to the emergency department presenting abdominal pain, nausea, and vomiting since the day after the procedure. Physical examination revealed hemodynamic instability, altered level of consciousness, diffuse abdominal pain, and a painful umbilical lump due to a complicated umbilical hernia. Emergent surgery was decided after preoperative assessment.

RESULTS

Intraoperative gastroscopy was performed, viewing a gastric ischemic ulcer covered with fibrin and a mucosal defect and suspecting a covered gastric perforation. Firstly, we performed an open approach to the complicated umbilical hernia. Subsequently, an exploratory laparoscopy was performed through the hernial ring, where a fibrin-covered area was evidenced in the anterior face of the gastric body, adhered to the round ligament by a transmural suture of the ESG. Additionally, multiple transmural sutures were observed adhered to the greater omentum and lesser sac and an intramural hematoma in the greater gastric curvature. No intra-abdominal free fluid was evidenced. A laparoscopic barbed suture of the area covered with fibrin was performed, after its release from the round ligament. The adhesions of the sutures and metallic material from the ESG were released. Finally, two abdominal drains were placed in the anterior and posterior gastric face. The patient presented superficial incisional surgical site infection and was discharged 6 days after laparoscopic surgery.

CONCLUSIONS

ESG is a novel procedure, which has proven to be an effective alternative in the treatment of obesity. However, this technique may have major complications that can require urgent surgery.

Provincial Review of Adherence to Age-specific Guidelines for Umbilical Hernia Repair and Trends in Management

BACKGROUND

Umbilical hernia (UH) is a common pediatric condition, for which delaying surgical repair for asymptomatic UH until after age 3 is recommended due to a high incidence of spontaneous closure. We aimed to determine the adherence to guidelines, rate of urgent surgical repair, outcomes, cost, and interinstitutional referral patterns of UH repair in the province of Quebec (Canada).

METHODS

This was a population-based retrospective cohort study of children 28 days to 17 years old who underwent UH repair between 2010 and 2020 using health administrative databases. Children who had multiple procedures, or prolonged peri-operative stays were excluded. Early repair was defined as elective surgery at or under age 3.

RESULTS

Of the 3215 children, 1744 (54.2%) were female, and 1872 (58.2%) were treated in a tertiary children's hospital. Guidelines were respected for 2853 out of 3215 children (89.7%). Patients living over 75 km from their treating hospitals (OR 2.36, 95% CI 1.33-4.16, P < 0.01), with pre-existing comorbidities (OR, 2.82; 95% CI, 1.96-4.05; P < 0.001), or being treated in a tertiary center (OR 2.10, 95% CI 1.45-3.03, P < 0.001) had a higher risk of early repair. Repair at or under age 3 and urgent surgery were associated with significant cost increases of 411$ (P < 0.001) and 558$ (P < 0.001), respectively.

CONCLUSION

Quebec has a high rate of adherence to age-specific guidelines for UH repair. Future research should explore factors that explain transfers into tertiary centers, and the extent to which these reflect efficient use of resources.

Age and Probability of Spontaneous Umbilical Hernia Closure

This cohort study of children younger than 6 years uses electronic health records to investigate whether a child’s age is associated with the probability of spontaneous umbilical hernia closure and to refine guidelines for surgical repair.

Spontaneous bowel evisceration through umbilical hernia in an adult non-cirrhotic patient

Few cases of spontaneous bowel evisceration (SBE) through umbilical hernias (UHs) in adult patients have been reported in the literature. Interestingly, the spontaneous rupture of the hernia sac is a rare complication usually seen in adult cirrhotic patients with persistent ascites or in patients with congenital wall defects. A man in his early 50s was admitted to our emergency department with SBE through a long-standing acquired UH. He was not clinically cirrhotic, although being HCV positive. Surgeons performed an urgent laparotomy with ileal resection, latero-lateral ileal anastomosis and direct hernioplasty without mesh. Given the rarity of this presentation, we reported it and reviewed the available literature on this subject. Elective hernioplasty is currently suggested to lower the risk of complications. Mesh placement should be preferred, but only if comorbidities and infectious risks do not contraindicate its use. In emergency situations, a direct hernia repair is preferred.

Assessing Alternative Approaches for Wound Closure in a National Pediatric Learning Health System

INTRODUCTION

Our objective was to perform a feasibility study using real-world data from a learning health system (LHS) to describe current practice patterns of wound closure and explore differences in outcomes associated with the use of tissue adhesives and other methods of wound closure in the pediatric surgical population to inform a potentially large study.

METHODS

A multi-institutional cross-sectional study was performed of a random sample of patients <18 y-old who underwent laparoscopic appendectomy, open or laparoscopic inguinal hernia repair, umbilical hernia repair, or repair of traumatic laceration from January 1, 2019, to December 31, 2019. Sociodemographic and operative characteristics were obtained from 6 PEDSnet (a national pediatric LHS) children's hospitals and OneFlorida Clinical Research Consortium (a PCORnet collaboration across 14 academic health systems). Additional clinical data elements were collected via chart review.

RESULTS

Of the 692 patients included, 182 (26.3%) had appendectomies, 155 (22.4%) inguinal hernia repairs, 163 (23.6%) umbilical hernia repairs, and 192 (27.8%) traumatic lacerations. Of the 500 surgical incisions, sutures with tissue adhesives were the most frequently used (n = 211, 42.2%), followed by sutures with adhesive strips (n = 176, 35.2%), and sutures only (n = 72, 14.4%). Most traumatic lacerations were repaired with sutures only (n = 127, 64.5%). The overall wound-related complication rate was 3.0% and resumption of normal activities was recommended at a median of 14 d (interquartile ranges 14-14).

CONCLUSIONS

The LHS represents an efficient tool to identify cohorts of pediatric surgical patients to perform comparative effectiveness research using real-world data to support medical and surgical products/devices in children.

Incarcerated Littre's Umbilical Hernia: A Case Report

Littre's hernia is an extremely rare type of hernia which has Meckel's diverticulum as its content. A 63-year-old male, presented to the emergency department with chief complaints of swelling and pain around the umbilicus. The patient was diagnosed with an incarcerated umbilical hernia. Following the emergency laparotomy, the intraoperative finding depicted an umbilical Littre's hernia. The patient underwent open Meckel's diverticulectomy with mesh repair. Preoperative diagnosis of Littre's hernia is unlikely due to its low incidence and lack of specific radiological and clinical findings, but the role of computed tomography scan and ultrasound are important in differentiating between strangulated or incarcerated bowel and omentum and in guiding the urgency of operative management.

Use of Bilateral Rectus Sheath Blocks in Open Umbilical Hernia Repair

BACKGROUND

In recent years, the rectus sheath block (RSB) has become increasingly prevalent in laparoscopic surgery. However, there is currently no definitive research on its use in the open repair of umbilical hernias with cirrhotic ascites.

OBJECTIVE

In this study, we assessed the safety and clinical efficacy of ultrasound-guided (US-guided) bilateral RSBs in open umbilical hernia repair for patients diagnosed with cirrhotic ascites.

STUDY DESIGN

Seventy-two patients diagnosed with umbilical hernias that presented with cirrhotic ascites and who were admitted to our hospital were randomly divided into 2 groups. These categories were labeled the RSB group (Group R) and the local infiltration group (Group L); we used US-guided RSBs in Group R and local infiltration in Group L.

SETTING

The clinical outcomes of the patients in each group were compared to one another. Heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were recorded at various time points in both groups.

METHODS

Measurements of the patients' outcomes were taken before anesthesia (T0), at the beginning of surgery (T1), at the time of the separation of the hernia sac (T2), at the end of surgery (T3), 6 hours postoperatively (T4), and 24 hours postoperatively (T5). On the Visual Analog Scale (VAS), pain scores at rest (T1-T3) and during activity (T4-T5) were recorded, as were the incidence of perioperative remedial analgesia and adverse effects.

RESULTS

Compared to T0, both groups' HR was significantly higher at T1-T3 (P < 0.05). The SBP and DBP were also significantly higher (P < 0.05). At T1-T3, the HR of Group R was significantly slower than that of Group L (P < 0.05), and at T4-T5, the VAS score for activity in Group R was significantly lower than that of Group L (P < 0.05). Group R had a significantly lower incidence of intraoperative remedial analgesia and postoperative nausea and vomiting than did Group L (P < 0.05). Neither group required postoperative remedial analgesia, and no patient experienced adverse reactions during the perioperative period.

LIMITATIONS

This study has limitations in its sample size, lack of blood ammonia levels, and absence of data on patient satisfaction, necessitating future studies to address these issues.

CONCLUSION

US-guided RSBs are an efficient method of anesthesia for open umbilical hernia repair in patients diagnosed with cirrhosis. This technique not only provides precise anesthesia and appropriate analgesia but also results in a low incidence of postoperative nausea and vomiting.

The impact of urgency of umbilical hernia repair on adverse outcomes in patients with cirrhosis: a population-based cohort study from England

INTRODUCTION

Umbilical hernia is common in patients with cirrhosis; however, there is a paucity of dedicated studies on postoperative outcomes in this group of patients. This population-based cohort study aimed to determine the outcomes after emergency and elective umbilical hernia repair in patients with cirrhosis.

METHODS

Two linked electronic healthcare databases from England were used to identify all patients undergoing umbilical hernia repair between January 2000 and December 2017. Patients were grouped into those with and without cirrhosis and stratified by severity into compensated and decompensated cirrhosis. Length of stay, readmission, 90-day case fatality rate and the odds ratio of 90-day postoperative mortality were defined using logistic regression.

RESULTS

In total, 22,163 patients who underwent an umbilical hernia repair were included and 297 (1.34%) had cirrhosis. More patients without cirrhosis had an elective procedure, 86% compared with 51% of those with cirrhosis (P < 0.001). In both the elective and emergency settings, patients with cirrhosis had longer hospital length of stay (elective: 0 vs 1 day, emergency: 2 vs 4 days, P < 0.0001) and higher readmission rates (elective: 4.87% vs 11.33%, emergency:11.39% vs 29.25%, P < 0.0001) than those without cirrhosis. The 90-day case fatality rates were 2% and 0.16% in the elective setting, and 19% and 2.96% in the emergency setting in patients with and without cirrhosis respectively.

CONCLUSION

Emergency umbilical hernia repair in patients with cirrhosis is associated with poorer outcomes in terms of length of stay, readmissions and mortality at 90 days.

Predictive value of hematological parameters in cirrhotic patients with open umbilical hernia repair

PURPOSE

Patients with liver cirrhosis sometimes suffer from high recurrence rates and postoperative complications. We previously reported that platelet-related hematological parameters are associated with the outcomes after incisional herniorrhaphy, and aim to evaluate the predictive value of these criteria in cirrhotic patients undergoing open umbilical herniorrhaphy.

METHODS

This is a retrospective study. The data of 95 cirrhotic patients undergoing open umbilical herniorrhaphy were analyzed. Patients were grouped based on the recurrence and defined hematological values. Platelet-multiple-lymphocyte index (PLM), neutrophil-leukocyte ratio, lymphocyte-monocyte ratio, platelet-neutrophil ratio, systemic immune-inflammation index, and aspartate aminotransferase-leukocyte ratio values were calculated based on preoperative blood analyses. The outcomes were obtained from hospital records and follow-up calls to patients.

RESULTS

Using cutoff values acquired by the Youden Index, we found a PLM value < 27.9, and the history of inguinal herniorrhaphy were revealed to be statistically significant in the recurrence based on univariant and multivariant analyses (p < 0.05). We further divided patients into two groups based on the cutoff value of PLM and found that a PLM value < 27.9 was significantly associated with the recurrence of incisional hernias (p = 0.018) and the occurrence of postoperative foreign sensation (p = 0.044), and tended to result in other postoperative complications such as cardiopathy, respiratory infection, hypoproteinemia, and hepatic diseases (p = 0.089).

CONCLUSION

The preoperative hematological values, especially PLM, may indicate the outcomes in cirrhotic patients after open umbilical herniorrhaphy. Accurate identification of risks may alert the intraoperative and postoperative care for patients.

Enhanced recovery after robotic ventral hernia repair: factors associated with overnight stay in hospital

PURPOSE

Enhanced recovery after surgery (ERAS) protocols lead to reduced post-operative stay and improved outcomes after most types of abdominal surgery. Little is known about the optimal post-operative protocol after robotic ventral hernia repair (RVHR), including the potential limits of outpatient surgery. We report the results of an ERAS protocol after RVHR aiming to identify factors associated with overnight stay in hospital, as well as patient-reported pain levels in the immediate post-operative period.

METHODS

This was a prospective cohort study of consecutive patients undergoing RVHR. Patients were included in a prospective database, registering patient characteristics, operative details, pain and fatigue during the first 3 post-operative days and pre- and 30-day post-operative hernia-related quality of life, using the EuraHS questionnaire.

RESULTS

A total of 109 patients were included, of which 66 (61%) underwent incisional hernia repair. The most performed procedure was TARUP (robotic transabdominal retromuscular umbilical prosthetic hernia repair) (60.6%) followed by bilateral roboTAR (robotic transversus abdominis release) (19.3%). The mean horizontal fascial defect was 4.8 cm, and the mean duration of surgery was 141 min. In total, 78 (71.6%) patients were discharged on the day of surgery, and factors associated with overnight stay were increasing fascial defect area, longer duration of surgery, and transverse abdominis release. There was no association between post-operative pain and overnight hospital stay. The mean EuraHS score decreased significantly from 38.4 to 6.4 (P < 0.001).

CONCLUSION

An ERAS protocol after RVHR was associated with a high rate of outpatient procedures with low patient-reported pain levels.

Switching from robotic-assisted extended transabdominal preperitoneal (eTAPP) to totally extraperitoneal (eTEP) hernia repair for umbilical and epigastric hernias

Our study aimed to assess the safety and effectiveness of the robotic-assisted extended totally extraperitoneal (eTEP) repair compared to transabdominal preperitoneal (eTAPP) repair with a suprapubic trocar insertion to treat umbilical and epigastric hernias. On a prospectively maintained database, we identified patients who underwent either eTEP or eTAPP for treating umbilical and epigastric hernias. During the study period, 53 patients were included, 32 in the eTEP group and 21 in the eTAPP group. The mean age was 59.0 ± 13.9 years, 45 patients (84.9%) were male, and the mean BMI was 28.0 ± 5.9 kg/m2. Most hernias were umbilical (81.1%) and primary (83.0%). The operative time for eTEP was slightly shorter than for eTAPP (106 ± 43 min vs. 126 ± 74 min, p = 0.232). Postoperatively, only one case of bleeding and one seroma were recorded. No complication occurred during a mean follow-up of 11.3 ± 6.4 months in the eTEP group and 20.5 ± 9.7 months in the eTAPP group. In conclusion, our study showed that the eTEP with suprapubic approach was safe and feasible in the treatment of epigastric and umbilical hernias. According to our experience, shorter operative time, integrity of the posterior layers and increased overlap size are the main surgical reasons of switching from eTAPP to eTEP.

Development of a low-cost congenital abdominal wall defect simulator (wall-go) for undergraduate medical education: a validation study

BACKGROUND

Congenital Anomalies were responsible for 303,000 deaths in the neonatal period, according to the WHO, they are among the world's top 20 causes of morbidity and mortality. Expensive simulators demonstrate several diseases, but few are related to congenital anomalies. This study aims to develop, validate, and evaluate low-cost simulator models (WALL-GO) of the most common abdominal wall defects, gastroschisis, and omphalocele, to enable diagnosis through an accessible tool with study value and amenable to replication.

METHODS

Market research was conducted to find materials to build low-cost models. The researchers built the model and underwent validation assessment of the selected experts who scored five or more in the adapted Fehring criteria. The experts were assessed through a 5-point Likert scale to 7 statements (S1-7). Statements were assigned values according to relevance in face and transfer validities. Concomitantly, the model was also evaluated by students from 1st to 5th year with the same instruments. Content Validity Indexes (CVIs) were considered validated between groups with concordance greater than 90%. Text feedback was also collected. Each statement was subjected to Fisher's Exact Test.

RESULTS

Gastroschisis and omphalocele model costs were US $15 and US $27, respectively. In total, there were 105 simulator evaluators. 15 experts were selected. Of the 90 students, there were 16 (1st year), 22 (2nd), 16 (3rd), 22 (4th), and 14 (5th). Students and experts obtained CVI = 96.4% and 94.6%, respectively. The CVIs of each statement were not significantly different between groups (p < 0,05).

CONCLUSIONS

The WALL-GO models are suitable for use and replicable at a manufacturable low cost. Mannequins with abdominal wall defects are helpful in learning to diagnose and can be applied in teaching and training health professionals in developing and low-income countries.

Leaking Umbilical Hernias in Cirrhotic Patients, Repair or Observe?

BACKGROUND

Umbilical hernias (UHs) in cirrhotic patients are common, can be quite complicated and are associated with significant morbidity and mortality. Leakage of ascites is a challenging entity and poses significant risks.

METHODS

This is a retrospective study of patients with cirrhosis and UHs with ascitic leakage. Patients were divided into two groups: patients managed operatively during index admission (Group 1) and those managed non-surgically during index admission (Group 2). Group 2 was further divided into those that subsequently underwent repair of UH and those managed medically.

RESULTS

Of 47 cirrhotic patients with leaking UHs, 19 patients were managed surgically during index admission (Group 1). In Group 2, 15 patients were managed non-surgically and 13 subsequently underwent surgery. The groups had comparable demographics, MELD-Na and Child-Pugh class. Group 2 had a higher rate of emergency surgery (92% vs 58%, P = .04) and higher rate of recurrence (31 vs. 0%, P = .02). The non-surgical patients in Group 2 had higher 1-year mortality (67%) compared to Group 1 (21%) and surgical patients in Group 2 (31%, P = .007). Multi-variable logistic regression for 1-year mortality demonstrated MELD-Na as the most significant risk factor (OR = 1.2, P = .05) and undergoing UH repair as the most significant protective factor (OR = .16, P = .02).

CONCLUSIONS

Cirrhotic patients with leaking UHs should undergo urgent repair. Non-operative management confers high risk of continued or increased ascitic leakage necessitating more emergent surgery. Despite high rate of post-operative complications related to cirrhosis, there is a clear mortality benefit to the repair of leaking UHs in cirrhotic patients.

Impact of consensus guideline publication on the timing of elective pediatric umbilical hernia repair

BACKGROUND

The American Academy of Pediatrics published consensus guidelines advising observation of asymptomatic umbilical hernias until age 4 or 5, given unnecessary risks of early intervention and substantial practice variation. Yet, the impact of guidelines on early repair (age <4) or if certain groups remain at risk for avoidable intervention is unclear.

METHODS

This retrospective study used data from children's hospitals participating in the Pediatric Health Information System database. Children aged 17 years and younger who underwent umbilical hernia repair from July 2017 to August 2022 were eligible for inclusion. Children with recurrent hernias, an emergency, or urgent presentation were excluded. An interrupted time series using segmented multivariable logistic regression estimated the association of guideline publication in November 2019 with the odds of guideline-adherent repair (age ≥4) after adjusting for sociodemographic characteristics and hospital-level random effects.

RESULTS

16,544 children underwent repair, of which 3,115 (18.8%) were children <4 years old. After adjustment, guideline publication was associated with an immediate increase in guideline-adherent repairs (odds ratio = 1.25 95% confidence interval = 1.05-1.49). The interrupted time series found that each month after publication was associated with a 2% increase in the odds of guideline-adherent repair (odds ratio = 1.02, 95% confidence interval = 1.01-1.03). Children with public insurance were nearly 20% less likely to receive guideline-adherent repair than privately insured children (odds ratio = 0.82, 95% confidence interval = 0.74-0.91). Children in the Midwest had lower odds of guideline-adherent repair (Midwest versus Northeast: odds ratio = 0.45. 95% confidence interval = 0.24-0.84).

CONCLUSION

Guideline publication was associated with greater odds of guideline-adherent repair, yet public insurance coverage and Midwest location remain significant predictors of early repair against recommendations.

Giant omphalocele: A novel approach for primary repair in the neonatal period using botulinum toxin

INTRODUCTION

Giant omphalocele (GO) is a complex condition for which many surgical treatments have been developed; however, no consensus on its treatment has been reached. The benefits and efficacy of botulinum toxin A (BTA) in the repair of large abdominal wall defects in adults has been proven, and its reported use in children has recently grown. The goal of this study is to describe a novel technique for primary repair of GO using BTA during the neonatal period and report our initial experience.

METHODS

patients were followed from August 2020 to July 2022. BTA was applied to the lateral abdominal wall in the first days of life followed by surgical repair of the abdominal defect.

RESULTS

while awaiting surgery, patients had minimal manipulation, without requiring mechanical ventilation, were on full enteral feeding, and in contact with their parents. The midline was approximated without tension and without the need for additional techniques or the use of a prosthesis. Patients were discharged with repaired defects.

CONCLUSION

this approach represents a middle ground between staged and the nonoperative delayed repairs. It does not require aggressive interventions early in life, allowing maintenance of mother-child bonding and discharge of the patient with a repaired defect without the need for additional techniques or the use of a prosthesis. We believe that this technique should be considered as a new possible asset when managing this complex condition.

The evidence mismatch in pediatric surgical practice

PURPOSE

Outpatient pediatric surgical practice often involves conditions of limited morbidity but significant parental concern. We explore existing evidence-based management recommendations and the mismatch with practice patterns for four common outpatient pediatric surgical conditions.

METHODS

Using the Cochrane Rapid Review Group recommendations and librarian oversight, we conducted a rapid review of four outpatient surgical conditions: dermoid cysts, epigastric hernias, hydroceles, and umbilical hernias. We extracted patient demographics, intervention details, outcome measures and evaluated justifications presented for chosen management options. A metric of evidence volume (patient/publication ratio) was generated and compared between diagnoses.

RESULTS

Out of 831 articles published since 1990, we identified 49 cohort studies (10-dermoid cyst, 6-epigastric hernia, 25-hydrocele, and 8-umbilical hernia). The 49 publications included 34,172 patients treated across 18 countries. The evidence volume for each outpatient condition demonstrates < 1 cohort/condition/year. The evidence mismatch rate varied between 33 and 75%; many existing recommendations are not evidence-based, sometimes conflicting and frequently misrepresentative of clinical practice.

CONCLUSIONS

Published literature concerning common outpatient pediatric surgical conditions is sparse and demonstrates wide variations in practice. All individual practice choices were justified using either risk of complications or patient preference. Most early intervention practices were based on weak or outdated studies and "common wisdom" rather than genuine evidence.

Giant Omphaloceles-Morbidity, Mortality, and Financial Impact of Early Versus Delayed Repair

INTRODUCTION

We compared strategy outcomes and financial impact over the first two years of life (F2YOL) for patients with giant omphaloceles undergoing early repair (ER) (primary or staged) versus delayed repair (DR).

METHODS

A retrospective review of giant omphaloceles (fascial defect > 5 cm/> 50% liver herniation) at a tertiary children's hospital between 1/1/2010 and 12/31/2019 was performed. Survival, length of stay, age at repair, ventilation days (VD), time to full enteral feeds, readmissions during the F2YOL, incidence of major associated anomalies, and total hospitalization charges during the F2YOL were compared. A subanalysis removing potential confounders and only including patients who underwent fascial closure within the F2YOL was also conducted.

RESULTS

Thirty four giant omphaloceles (23DR and 11ER) were identified. The median age (days) at repair was 289 [148, 399] DR versus 10 [5, 21] ER, P < 0.001. Total cohort two-year survival was significantly higher in the DR group (95.7% versus 63.6%, P = 0.03). Including patients with a tracheostomy there was no significant difference in VD during the index hospitalization. Excluding tracheostomy patients, the DR group had significantly fewer VD during the index hospitalization, 15 [0, 15] versus 18 [10, 54], P = 0.02 and over the F2YOL 6.5 [ 0, 21] versus 18 [14, 43], P = 0.03. There were no significant differences in the incidence/type of major associated anomalies, time to full enteral feeds, index length of stay, total hospital days, total admissions, or associated hospital charges. On subanalysis, there was no significant difference in VD or survival at any time.

CONCLUSIONS

Delayed and early repair strategies for giant omphaloceles have equivalent outcomes in the index hospitalization and over the course of the first two years of life. These findings are useful for family counseling and expectation setting.
