Jejunoileal Atresia: A National Cohort Study

Jejunal Atresia With a Rare Association: A Case Report and Literature Review

Jejunoileal atresia, a common cause of neonatal intestinal obstruction, typically manifests shortly after birth. This case report highlights a rare instance of a late preterm female neonate presenting with type 4 jejunoileal atresia along with proximal rectal atresia, an exceedingly uncommon combination. Initial symptoms included bilious emesis and failure to pass meconium, leading to surgical correction of jejunoileal atresia. However, postoperative complications, including vomiting and jaundice, prompted further investigation, revealing rectal atresia during a fluoroscopic study on day 29. Subsequent surgery was required to address the rectal atresia, resulting in additional challenges such as short bowel syndrome and infection. The complexity of diagnosis and management underscores the importance of thorough evaluation of the lower gastrointestinal tract in neonates with jejunoileal atresia to prevent misdiagnosis and reduce the need for multiple surgeries. Rectal atresia, which is a very rare anorectal abnormality, in combination with jejunoileal atresia is considered an incredibly unusual, exceptionally unique case; as to our knowledge, no similar presentation had previously occurred. Prompt identification and simultaneous treatment of both conditions can help mitigate complications, minimize the risk of necrosis and perforation, and improve overall outcomes. Comprehensive management strategies that encompass thorough diagnostic evaluation and coordinated surgical interventions are crucial for optimizing the care of neonates with complex intestinal malformations, ensuring timely resolution of symptoms, and reducing long-term morbidity.

Clinical characteristics of postoperative necrotizing enterocolitis in patients with congenital jejunoileal atresia and its risk factors

Objective

To review postoperative necrotizing enterocolitis (NEC) in patients with jejunoileal atresia (JIA) and to explore the potential risk factors related to the concurrence of NEC.

Methods

Patients diagnosed with JIA who received surgical treatment from January 2016 to June 2021 were enrolled. Demographics, viral infection of the fetus, transfusion within 48 hours before NEC, sepsis before JIA repair, pathological and anatomical classification of JIA, combined malformation, occurrence time of NEC after the operation, treatment, and prognosis of patients were analyzed. Patients were divided into NEC group and non-NEC group, and all patients were followed up for 3-6 months to observe for complications.

Results

A total of 180 patients with JIA were included, of whom 12 were diagnosed with NEC after surgery and 1 patient with NEC died during follow-up. The average age, birth weight, gestational age, proportion of premature infants, proportion of preoperative infections, and pathological classification of JIA did not significantly differ between the two groups. The probability of patients with proximal jejunal atresia (PJA) in the NEC group (58.3%) was higher than that in the non-NEC group (22.6%) (p=0.011), and patients with PJA had longer parenteral nutrition time than patients without PJA (26.64±9.21 days vs 15.11±6.58 days, p<0.001).

Conclusion

PJA was more likely to be associated with concurrent NEC after surgery, which is a highly NEC-related risk factor inherent in JIA.

Type IIIb jejunal atresia treated surgically with two end-to-end anastomoses

A term newborn presented after birth with abdominal distension and vomiting in a developing country in Asia. Ultrasonography suggested intestinal obstruction and abdominal X-ray showed a 'double-bubble' sign suggestive of intestinal atresia. The newborn was diagnosed with early-onset neonatal sepsis secondary to intestinal obstruction and transferred to the neonatal intensive care unit. Surgery was performed and type IIIb jejunal atresia was found. Type IIIa/b jejunal atresia is associated with high incidence of poor outcome in lower socioeconomic countries. The affected intestinal segment and a distal serosal tear were resected and two end-to-end anastomoses formed. Oral feeding commenced on day 13 postoperatively. The patient was discharged on day 20 with adequate nutritional status. At follow-up, the patient continued to thrive. An operation involving resection of two different segments of bowel repaired with two end-to-end anastomoses in a neonate had a successful outcome for the patient.

Fetal congenital gastrointestinal obstruction: prenatal diagnosis of chromosome microarray analysis and pregnancy outcomes

OBJECTIVE

The aim of this study was to investigate the incidence of chromosome anomalies in different types of congenital gastrointestinal obstruction and assess pregnancy outcomes of fetuses with congenital gastrointestinal obstruction.

METHODS

A total of 64 cases with gastrointestinal obstruction between January 2014 and December 2020 were enrolled in this study. They were divided into three groups according to sonographic images. Group A: isolated upper gastrointestinal obstruction; Group B: isolated lower gastrointestinal obstruction; Group C: non-isolated gastrointestinal obstruction. The rate of chromosome anomalies in different groups was calculated. Pregnant women with amniocentesis were followed up by medical records and telephone. The follow-up included pregnancy outcomes and development of the live born infants.

RESULT

From January 2014 to December 2020, there were 64 fetus with congenital gastrointestinal obstruction underwent chromosome microarray analysis(CMA), the overall detection rate of CMA testing was 14.1%(9/64). The detection rate of Group A, B and C were 16.2%, 0 and 25.0% respectively. 9 fetuses with abnormal CMA results were all terminated. Among 55 fetuses with normal chromosomes, 10(18.2%) fetuses were not found to have any gastrointestinal obstruction after birth. 17(30.9%) fetuses were diagnosed with gastrointestinal obstruction and underwent surgical treatment after birth, one of which had lower gastrointestinal obstruction combined with biliary obstruction and died due to liver cirrhosis. 11(20.0%) pregnancy were terminated due to multiple abnormalities. 5(9.1%) fetuses were intrauterine death. 3(5.5%) fetuses were neonatal deaths. 9(16.4%) fetuses were lost to follow-up.

CONCLUSION

It is crucial to understand whether the gastrointestinal tract abnormality is isolated or associated to other findings. The risk of chromosomal abnormalities in fetuses with isolated lower gastrointestinal obstruction is lower than upper gastrointestinal obstruction. While genetic abnormalities excluded, a promising prognosis is expected for fetuses with congenital gastrointestinal obstruction.

Thinking outside the box: a review of gastrointestinal symptoms and complications in cystic fibrosis

INTRODUCTION

Gastrointestinal (GI)-related symptoms, complications, and comorbidities in cystic fibrosis (CF) are common and research to reduce their burden is a priority for the CF community. To enable future research, this review aimed to summarize the range of GI symptoms, complications and comorbidities seen in CF, the underlying pathophysiology, and treatments.

AREAS COVERED

This was a rapid systematic review undertaken using the recommendations from the Cochrane Rapid Reviews Methods Group. We searched databases including PubMed, Embase, Medline and the Cochrane database and identified those studies reporting GI-related symptoms, complications, or comorbidities in CF or their treatment. Our searches identified 2,930 studies and a total 119 studies met our inclusion criteria. Where a prevalence could be determined, GI symptoms were reported in 33.7% of study participants. The range of symptoms reported was broad and the highest median prevalence included flatulence (43.5%), bloating and abdominal distension (36%), and fatty stool (36%). Meconium ileus was reported in 12% and distal intestinal obstruction syndrome in 8.5.

EXPERT OPINION

GI-related symptoms, complications, and comorbidities in CF are common. More consistent characterization and recording of these symptoms in clinical studies may help achieve the priority of reducing the burden of GI disease in CF.

Perioperative and Long-Term Outcome in Patients Treated for Jejunoileal Atresia

OBJECTIVES

Jejunoileal atresia is a common cause of neonatal intestinal obstruction. Results of long-term outcome are very limited. The aim of this study was to describe perioperative and postoperative outcome, and to evaluate long-term gastrointestinal quality of life (QoL) in patients treated for jejunoileal atresia.

METHODS

We conducted a combined retrospective and cross-sectional observational study of patients treated for jejunoileal atresia during 2001-2019. Perioperative data were registered, and complications were classified according to the Clavien-Dindo classification. To evaluate long-term clinical status and QoL, the PedsQL Gastrointestinal Symptoms Scales questionnaire and a self-designed questionnaire were used. Approval from the Data Protection Office was obtained.

RESULTS

Seventy patients were included in the retrospective part of the study. Of these, 70% got a primary anastomosis. Concomitant anomalies were registered in 46%. Median length of stay was 28 (5-140) days. Early (<28 days) complication rate was 66%. Early abdominal surgical reinterventions were performed in 11%, most frequently due to anastomotic leak. Late (>28 days) abdominal surgical reinterventions were performed in 21%, and most commonly for bowel obstruction. Overall mortality rate was 4%. Thirty-two patients with median 8 (2-19) years returned the questionnaires. Overall gastrointestinal QoL was good. However, concomitant gastrointestinal anomalies were associated with impaired outcome. Embarrassment of the scar was reported in 38%. Three (9%) patients used medication (laxatives, proton pump inhibitor) for gastrointestinal symptoms.

CONCLUSIONS

Jejunoileal atresia is associated with significant morbidity during initial treatment. Despite this, the majority of the patients have excellent long-term outcomes.

Abdominal Surgical Emergencies in Neonates

Abdominal surgical emergencies are relatively common in neonates. Some of them are related to congenital diseases such as intestinal atresia and intestinal malrotation, whereas some are entirely postnatal conditions such as necrotizing enterocolitis and gastric perforation. While there is a wide range of clinical severity for these conditions, outcomes are most favorable with prompt identification and expeditious treatment. In this review, we describe the most common neonatal abdominal surgical emergencies, highlight the signs that can help with early detection, and explain the approach to diagnosis and management.

A Novel DNAH9 Gene Mutation Causing Primary Ciliary Dyskinesia With an Unusual Association of Jejunal Atresia in a Bahraini Child

Primary ciliary dyskinesia (PCD) is a rare autosomal recessive genetic disorder. It is caused by a defect in the action of the cilia lining multiple organs of the body, including the lungs, the sinuses, hepatobiliary and reproductive organs. In general, the estimated prevalence of this condition is one in 15,000-20,000 individuals. It is characterized by the triad of chronic sinusitis, bronchiectasis, and situs inversus, which occurs in 50% of the cases. It can be associated with other diseases too. Genetic studies can aid in confirming the diagnosis of this condition. A high degree of suspicion about PCD among pediatricians, neonatologists, otorhinolaryngologists, and pulmonologists is essential to make early referrals of patients before they develop irreversible lung damage. Hence, early diagnosis and appropriate treatment are very important. Multicenter collaborations might improve the quality of treatment and patient outcomes. Here, we discuss a case of PCD with a unique association with type IIIb jejunal atresia, and developmental delay secondary to vitamin B12 deficiency. Moreover, the patient was found to have a novel DNAH9 gene mutation in a compound heterozygous state. This is the first case of this rare disease to be reported from Bahrain. This case report is also associated with an extensive literature review.

A Case of Jejunal Atresia Associated With Heterotrophic Pancreas and Meckel's Diverticulum

Apart from meconium ileus, amniotic fluid plug syndrome, malrotation of the gut, Hirschprung's disorder, trauma, and other rare causes, bowel atresia is one of the most common causes of bowel obstruction in newborns. Jejunal atresia can affect multiple lengths of the bowel. The higher the level of atresia, the greater the severity. The outcome of bowel atresia related to surgical repair is favorable. In general, both mortality and morbidity are affected by affiliated medical conditions such as preterm birth, cystic fibrosis, and other congenital anomalies; the sophistication of the lesion; and surgical complications. We present the case of a one-day-old baby who had two episodes of bilious vomiting with abdominal distension within 10 minutes of birth. The baby was advised to undergo ultrasonography of the abdomen and pelvis for further evaluation, and the findings were reported.

Differences in the Outcome of Colonic Atresia with and without Abdominal Wall Defects

INTRODUCTION

 Colonic atresia (CA) is a very rare disease. Two entities of CA can be differentiated: primary CA and CA with abdominal wall defects (AWD). This study aimed to investigate the differences between these two entities, especially for long-term outcomes.

MATERIALS AND METHODS

 Data from the major health insurance company (AOK) were analyzed. Sixty-two patients with ICD-10 codes Q42.1-2 and Q42.8-9 (atresia of the colon and rectum) who underwent surgery within 10 days after their first admission between 2007 and 2016 were obtained.

RESULTS

 Twenty-nine patients had an AWD, and 33 patients had primary colonic atresia (PCA). Significant differences between patients with PCA and AWD were found regarding prematurity but not for other concomitant malformations. Ostomy was the initial therapy of choice for 87.9% (29/33) of patients with PCA and 65.5% (19/29) with AWD. Central venous access was significantly more often in patients with AWD. Overall, patients with CA have an excellent short-term outcome. The 1-year mortality was 3% (1/33) in PCA and 6.9% (2/29) in AWD. Delayed management did not lead to higher mortality. Higher number of admission days and higher hospital costs were related to gastrostomy and short bowel in the long term.

CONCLUSION

 The long-term outcome of CA is related to short bowel and need for initial gastrostomy but not related to AWD, prematurity, or associated anomalies.

Incidence of late severe intestinal complications after bowel atresia/stenosis

BACKGROUND

To determine the incidence and risk factors for late severe intestinal complications after surgical repair for intra-abdominal congenital intestinal atresia/stenosis.

METHODS

We included 51 patients who underwent surgical repair for congenital intestinal atresia/stenosis. Late severe intestinal complications included adhesive ileus, incisional hernia, or volvulus. Whether surgical intervention was urgent or not was recorded. The location of the atresia/stenosis was classified into two groups: atresia/stenosis located at the oral or anal side from the Treitz ligament. The type of atresia/stenosis was classified as low-risk types (type I, mucosal web/II, fibrous cord/IIIa, mesenteric gap defect) and high-risk types (IIIb, apple peel/IV, multiple atresia). We compared the incidence of late intestinal complications between the location of intestinal atresia/stenosis at the oral and anal side of Treitz ligament, and between low- and high-risk types of atresia/stenosis using Fisher's exact test.

RESULTS

Eight (15.7%) had late intestinal complications, all of which occurred in patients with intestinal atresia/stenosis located on the anal side of the ligament of Treitz. Urgent surgical intervention was needed in four cases. There was a significant difference in the location of atresia/stenosis (with vs. without late intestinal complications at oral/anal side of the Treitz ligament: 0/8 vs. 24/19; P = 0.005) and the type of intestinal atresia/stenosis (with vs. without that accompanying low-/high-risk type: 5/3 vs. 41/2; P = 0.023).

CONCLUSIONS

Physicians should consider the presence of intestinal complications that require surgical intervention in patients undergoing surgical reconstruction for jejunal and ileal atresia/stenosis with abdominal symptoms.
