The role of a simple questionnaire predicting treatment success in children with ACNES.

BACKGROUND: Some children with chronic abdominal wall pain or groin pain do not have an inguinal hernia but suffer from anterior cutaneous nerve entrapment syndrome (ACNES). Diagnosing ACNES is challenging, especially in children as a diagnostic gold standard is lacking. A paediatric questionnaire containing 17 simple items was earlier found to discriminate between abdominal pain due or ACNES or IBS. Scores range from 0 points (ACNES very unlikely) to 17 points (ACNES very likely). The present study investigates whether this 17-item questionnaire predicted treatment success in children receiving therapy for ACNES. METHODS: Children < 18 years who presented in a single institute between February 2016 and October 2021 with symptoms and signs suggestive of ACNES completed the questionnaire before intake and treatment. Treatment success after 6-8 weeks was defined as self-reported 'pain-free' (group 1), ' > 50% less pain' (group 2) and ' < 50% less pain' (group 3). Group differences regarding sex, age, BMI, symptoms duration and questionnaire scores were analysed. RESULTS: Data of 145 children (female 78%, mean age 14.7 ± 2.3 years, mean BMI 21.1 ± 3.9) were analysed. All children received a diagnostic trigger point injection using an anaesthetic agent, and 75.5% underwent subsequent surgery for untractable pain. The three groups were comparable regarding sex distribution, age, BMI and symptoms duration. In addition, questionnaire scores were not different (group 1: n = 89, mean score 13.4 ± 2.7, group 2: n = 24, 13.4 ± 2.3 and group 3: n = 32, 13.0 ± 2.7, p > 0.05). CONCLUSIONS: Treatment success was attained in 78% of children undergoing surgery for ACNES. A simple questionnaire scoring items associated with abdominal pain did not predict treatment success.

Laparoscopic Roux-en-Y feeding jejunostomy as a long-term solution for severe feeding problems in children.

Enteral feeding is a common problem in children with gastric emptying disorders. Traditional feeding methods in these patients often show a high rate of complications and maintenance issues. Laparoscopic Roux-en-Y feeding jejunostomy (LRFJ) has been described in a few patients as a minimal invasive option for enteral access in these children. The aim of this study is to evaluate the outcomes of the LRFJ procedure in our tertiary referral center. We conducted a retrospective case-series including all patients, aged 0-18 years old, that underwent a LFRJ procedure between August 2011 and December 2020 for the indication of oral feeding intolerance due to delayed gastric emptying. Outcomes evaluated were complications (short and long term) and parenteral satisfaction. In total, 12 children were identified that underwent LRFJ for the indication of oral feeding intolerance due to delayed gastric emptying. A total of 16 complications were noted in 8/12 patients (67%). Severity classified by Clavien-Dindo were grade I (n = 13), grade II (n = 1), and grade IIIB (n = 2). In 11/12 patients, parents were satisfied with the results. CONCLUSIONS: Although minor complications after LRFJ are common in our patients, this technique is a safe solution in patients with gastric emptying disorders leading to a definitive method of enteral feeding and high parenteral satisfaction. WHAT IS KNOWN: • Traditional tube feeding in children (duodenal, PEG-J-tubes) with severe delayed gastric emptying can be challenging with a high rate of complications and maintenance issues. • Open loop jejunostomy and Roux-en-Y jejunostomy are alternative, permanent methods of feeding but either invasive or are accompanied by severe complications. Little is known in the literature about laparoscopic Roux-en-Y feeding jejunostomy. WHAT IS NEW: • Laparoscopic Roux-en-Y feeding jejunostomy is a permanent, safe and minimal invasive alternative option for enteral feeding in children with severe delayed gastric emptying..

Distress and post-traumatic stress in parents of patients with congenital gastrointestinal malformations: a cross-sectional cohort study.

BACKGROUND: Congenital gastrointestinal malformation (CGIM) require neonatal surgical treatment and may lead to disease-specific sequelae, which have a potential psychological impact on parents. The aim of this study is to assess distress and symptoms of post-traumatic stress disorder (PTSD) in parents of patients with CGIM. In this cross-sectional study, seventy-nine parents (47 mothers and 32 fathers) of 53 patients with CGIM completed the Distress Thermometer for Parents (DT-P) and the Self Rating Scale for Posttraumatic Stress Disorders (SRS-PTSD) as part of the multidisciplinary follow-up of their children (aged 5-35 months). Group differences were tested between parents and representative Dutch reference groups with regard to rates of (clinical) distress and PTSD, and severity of overall distress and PTSD, for mothers and fathers separately. Mixed model regression models were used to study factors associated with the risk of (clinical) distress, PTSD and with severity of symptoms of PTSD (intrusion, avoidance and hyperarousal). RESULTS: Prevalence of clinical distress was comparable to reference groups for mothers (46%) and fathers (34%). There was no difference in severity of overall distress between both mothers as well as fathers and reference groups. Prevalence of PTSD was significantly higher in mothers (23%) compared to the reference group (5.3%) (OR = 5.51, p < 0.001), not in fathers (6.3% vs 2.2.%). Symptoms of intrusion were commonly reported by all the parents (75%). Longer total length of child's hospital stay was associated with more severe symptoms of intrusion, avoidance and hyperarousal. Child's length of follow-up was negatively associated with severity of intrusion. CONCLUSIONS: Having a child with CGIM has a huge impact on parents, demonstrated by a higher prevalence of PTSD in mothers, but not fathers, compared to parents in the general population. Monitoring of symptoms of PTSD of parents in follow-up is necessary.

Diagnostic accuracy of abdominal ultrasound to detect pathology that needs surgical exploration in children with umbilical discharge.

BACKGROUND: Umbilical discharge is common in children and mostly attributed to infection or granuloma. However, an underlying congenital abnormality warranting surgery might also be present. Ultrasound is the imaging modality of choice to diagnose the presence of a congenital abnormality. The aim of this study is to investigate diagnostic accuracy of the ultrasound to detect pathology requiring surgical excision. METHODS: All patients ≤18 years with umbilical discharge from January 2008 to September 2019 were retrospectively included. Diagnostic accuracy, i.e., sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR-), were calculated. RESULTS: Eighty-one patients were included and 56 were operated. The ultrasound was false positive in 10 patients and false negative in 13 patients. The sensitivity of ultrasound was 71.1% (95% CI 55.7-83.6), specificity 72.2% (54.8-85.8), PPV 76.2% (64.7-84.8), NPV 66.7% (54.8-76.8), LR+ 2.6 (1.5-4.5) and LR- 0.40 (0.2-0.7). CONCLUSIONS: This study shows that the diagnostic accuracy of ultrasound for detecting underlying congenital abnormalities warranting surgery for umbilical discharge in the pediatric population is low, even with experienced pediatric radiologists. Therefore, the role of the ultrasound in the diagnostic workup and value in clinical decision making is limited. TYPE OF STUDY: Study of diagnostic test. LEVEL OF EVIDENCE: III.

[Revised guideline for acute appendicitis. Amendments to diagnostics and treatment]. / Herziene richtlijn over acute appendicitis.

Recently, the revised guideline 'Guideline for diagnostics and treatment of acute appendicitis' was published by the Dutch Surgical Society. A patient with limited clinical symptoms and low suspicion of appendicitis can be assessed again at a later time, during which ultrasound diagnostics can be repeated. Following an inconclusive ultrasound scan in children who possibly have appendicitis, it is no longer recommended to perform diagnostic laparoscopy; rather, MRI diagnostics are indicated. In young adults with possible appendicitis, in whom a diagnosis cannot be established using ultrasound, the advice is to use MRI diagnostics instead of CT imaging; this particularly applies to women of child-bearing age. For patients with appendicitis an appendectomy remains the recommended treatment, although one can consider treating adults with suspected simple appendicitis with antibiotics alone. It is important that this decision is made in consultation with the patient. Laparoscopic appendectomy reduces the number of wound infections and admission length, and is therefore usually preferred over open method appendectomy. If a patient with appendicitis is 24-28 weeks pregnant,consultation with a specialist centre is indicated regarding the obstetric management and possibly referral.

[Acute appendicitis: treatment in accordance with new guideline]. / Acute appendicitis.

In this clinical lesson we present two patient cases. A 66-year-old female patient with a clinical, biochemical and radiological suspicion of complex appendicitis. The patient undergoes an appendectomy and post-operative recovery is beset with complications. The other case involves a 24-year-old male patient with suspected simple appendicitis. He is successfully treated with antibiotics and without surgery. By using these patients as examples, we discuss the revised clinical guideline for diagnosing and treating acute appendicitis. Besides that, we also discuss the differentiation between simple and complex appendicitis and how this can influence the treatment plan.

Imaging in pediatric appendicitis is key to a low normal appendix percentage: a national audit on the outcome of appendectomy for appendicitis in children.

PURPOSE: A laparoscopic approach for emergency appendectomy is increasingly used, in pediatric patients as well. The objective of this study is to audit the current state of diagnostic work-up, surgical techniques and its outcome in children with acute appendicitis. METHODS: A prospective consecutive observational cohort study was carried out in a 2-month study period. All patients under 18 years that were operated for suspected acute appendicitis were included. Primary outcome was the infectious complication rate after open and laparoscopic approach; secondary outcomes were preoperative use of imaging and post-operative predictive value of imaging, normal appendix rate and children with a postoperative ileus. RESULTS: A total of 541 children were operated for suspected acute appendicitis in 62 Dutch hospitals. Preoperative imaging was used in 98.9% of children. The normal appendix rate was 3.1%. In 523 children an appendectomy was performed. Laparoscopy was used in 61% of the patients and conversion rate was 1.7%. Complicated appendicitis was diagnosed in 29.4% of children. Overall 30-day complication rate was 11.9% and similar after open and laparoscopic. No difference was found in superficial surgical site infections, nor in intra-abdominal abscesses between the open and laparoscopic approach. Complicated appendicitis is an independent risk factor for infectious complications. CONCLUSION: The laparoscopic approach is most frequently used, except for young children. Superficial surgical site infections are more frequent after open surgery only in patients with complicated appendicitis. The normal appendix rate is low, most likely because of routine preoperative imaging.

[Mesenteric venous thrombosis during pregnancy; a rare cause of acute ischaemia of the small intestine]. / Veneuze mesenteriale trombose tijdens de zwangerschap.

BACKGROUND: Acute ischaemia of the small intestine is caused by mesenteric venous thrombosis in 5-15% of patients. The non-specific symptoms frequently lead to a diagnostic delay. CASE DESCRIPTION: A 30-year-old pregnant woman presented at the accident and emergency department with progressive abdominal pain, nausea and vomiting. During admission the patient developed signs of peritonitis. Diagnostic laparoscopy revealed a picture of mesenteric venous thrombosis, and we resected 170 cm ischemic small intestine. No underlying cause was identified, apart from the pregnancy. The patient was treated with low-molecular-weight heparin and later gave birth to a healthy child. CONCLUSION: If a patient presents with (unexplained) progressive abdominal symptoms and disproportional abdominal pain without peritonitis, the possibility of intestinal ischaemia should be considered during differential diagnosis.

The impact of disease severity, age and surgical approach on the outcome of acute appendicitis in children.

PURPOSE: Although a national guideline has been implemented, the optimal approach for appendectomy in children remains subject of debate in the Netherlands. Opponents of laparoscopy raise their concerns regarding its use in complex appendicitis as it is reported to be associated with an increased incidence of intra-abdominal abscesses. The aim of this study was to evaluate the outcome of surgical approaches in both simple and complex appendicitis in paediatric patients. METHODS: A 10-year retrospective cohort study was performed (2001-2010) in paediatric patients treated for suspected acute appendicitis. Patients were divided into either simple or complex appendicitis and into different age groups. Primary outcome parameters were complication rate (intra-abdominal abscess (IAA), superficial surgical site infection (SSI) and readmission) and hospital stay. RESULTS: In total, 878 patients have been treated (median age 12, range 0-17 years). Two-thirds of the patients younger than 6 years had complex appendicitis, compared to one quarter in the group aged 13-18. In the complex appendicitis group, LA was associated with more IAA and early readmissions. In the simple appendicitis group, the complication rate was comparable between the two approaches. Significantly more IAAs were seen after LA in the youngest age group. CONCLUSION: This study demonstrates the unfavourable outcome of LA in the youngest age group and in patients with complex appendicitis. Therefore, we advise to treat these patients with an open approach.

Issues in the management of simple and complex meconium ileus.

INTRODUCTION: Various surgical methods are used to treat meconium ileus (MI), including resection with enterostomy (RES), primary anastomosis (RPA), and purse-string enterotomy with intra-operative lavage (PSI). The aim of this study is to discuss the surgical treatment of MI, based on our experience. PATIENTS AND METHODS: Of the 41 MI patients treated at our institution between 1984 and 2007, 18 had simple MI and 23 had complex MI. These groups were analyzed according to treatment modality, concentrating on length of hospital stay, complications [peritonitis, septicemia, adhesive small bowel obstruction (ASBO), and malabsorption/diarrhea], need for additional surgical procedures, mortality. RESULTS: Of the 18 patients with simple MI, 7 (39%) were successfully treated with diluted Gastrografin® enema. The remaining 11 patients were treated surgically: two underwent RPA, of whom one died; five had RES, of whom one developed ASBO; four underwent PSI, of whom two developed peritonitis. In the complex MI group, 14 patients underwent RPA, with peritonitis occurring in three (one died); nine underwent RES, of whom two developed ASBO. CONCLUSION: In patients with simple MI, conservative treatment with diluted Gastrografin® enema is an effective initial treatment in our hands. In case of failure, RES is advisable. Patients with complex MI are candidates for RES. RPA and PSI seem to have higher complication rates.

Clinical and genetic characteristics of meconium ileus in newborns with and without cystic fibrosis.

The present study compares the clinical presentation and diagnostic features of meconium ileus (MI) in newborns with and without cystic fibrosis (CF). A retrospective study of 43 patients treated in the Pediatric Surgical Center of Amsterdam was performed. Twenty-three of the patients (53.5%) were diagnosed as having CF. Complex MI was significantly more frequent in patients without CF, and these patients had lower gestational ages and birth weights than patients with CF. All of the patients with complex MI had homozygous DF508 mutations, whereas the patients with simple MI also had other mutations. None of the patients with other mutations had complex MI. Therefore, we conclude that the clinical entity of MI represents a spectrum of underlying pathologies.

Management of trichobezoar: case report and literature review.

Trichobezoars (hair ball) are usually located in the stomach, but may extend through the pylorus into the duodenum and small bowel (Rapunzel syndrome). They are almost always associated with trichotillomania and trichophagia or other psychiatric disorders. In the literature several treatment options are proposed, including removal by conventional laparotomy, laparoscopy and endoscopy. We present our experience with four patients and provide a review of the recent literature. According to our experience and in line with the published results, conventional laparotomy is still the treatment of choice. In addition, psychiatric consultation is necessary to prevent relapses.
