Jejunoileal Atresia: Factors Affecting the Outcome and Long-term Sequelae

Neurodevelopmental outcomes among children with congenital gastrointestinal anomalies using Korean National Health Insurance claims data

This study investigated neurodevelopment and risk factors in children surgically treated for congenital gastrointestinal anomalies (CGIA), excluding those with known high-risk factors such as low birth weight or chromosomal anomalies. Data of children born between 2008 and 2015 who underwent surgical treatment for CGIA were retrieved from the Korean National Health Insurance Database. CGIA included esophageal atresia, duodenal atresia, jejunoileal atresia, anorectal malformations, and congenital megacolon. Neurodevelopmental impairment (NDI) was defined as Korean Ages and Stages Questionnaire scores below the determined cut-off or Korean Developmental Screening Test scores < 2 standard deviations at 3 years of age. Children with CGIA had a significantly higher risk of NDI than controls (6.2% vs. 2.7%, p < 0.001). Growth failure was correlated with NDI. Longer durations of oxygen support (adjusted odds ratio [aOR], 1.037; 95% confidence interval [CI], 1.013-1.063), mechanical ventilation (aOR, 1.053; 95% CI, 1.018-1.089), and number of surgeries (aOR, 1.137; 95% CI, 1.016-1.273) were significantly associated with NDI. These findings emphasize that cautious yet proactive neurodevelopmental monitoring is crucial in affected children, ensuring timely intervention and that excessive concern among families is unnecessary.

Utility of the web excision with pre-membranous incision for congenital intestinal atresia-type I and stenosis

PURPOSE

This study analyzed the efficacy of web excision combined with a pre-membranous incision on the dilated proximal segment for congenital intestinal atresia with type I and stenosis (CIA-I/S).

PATIENTS AND METHODS

Twenty-six patients underwent surgery for CIA-I/S from January 1990 to June 2022. Patients were categorized into 3 groups according to the surgical procedure: Group A, web excision with pre-membranous incision of the dilated intestine (n = 14); Group B, enteroplasty with a trans-membranous vertical incision (n = 7) and Group C, diamond-shaped anastomosis (n = 5). To minimize the impact of obstruction location on outcomes, we specifically examined 17 cases of duodenal atresia/stenosis: Group D-A, (n = 6); Group D-B, (n = 6) and Group D-C, (n = 5). We retrospectively compared the operative and postoperative parameters among the three groups.

RESULTS

No patient experienced anastomotic leakage or obstruction. There were no significant differences in operative duration or blood loss among the 3 Groups. The median time to feeding initiation was 4, 6.5, and 5 days in Groups A, B, and C, respectively (p = 0.04) and was 4, 6.5, and 5 days in Groups D-A, D-B, and D-C, respectively (p = 0.04).

CONCLUSION

Web excision, when compared to enteroplasty and diamond-shaped anastomosis, showed comparable results in terms of the operative duration and postoperative complications. However, it may allow for an earlier initiation of enteral nutrition.

Importance of Prenatal Diagnosis of Ileal Atresia in Gestational Diabetes Cases

BACKGROUND Maldevelopment of the fetal bowel can result in the rare condition of intestinal atresia, which results in congenital bowel obstruction. This report describes a case of prenatal diagnosis of fetal ileal atresia at 22 weeks' gestation. CASE REPORT Here, we present a 24-year old woman who was 22 weeks into her first pregnancy when she underwent routine fetal ultrasound. She was diagnosed with gestational diabetes mellitus. Her body mass index was normal and she had normal weight gain. The ultrasonographic examination performed revealed a hyperechoic bowel and a small dilatation of the bowel. The couple was counselled for possible intestinal atresia and its postnatal implications. At 33 weeks of gestation, polyhydramnios appeared, and the intestinal distension was much more pronounced, with hyperechoic debris in the intestinal lumen (succus-entericus). After birth, surgery was performed and we concluded the patient had type II atresia, which was surgically treated. CONCLUSIONS This report has highlighted the importance of antenatal ultrasound in detecting fetal abnormalities, and has shown that rare conditions such as intestinal atresia can be accurately diagnosed and successfully managed. Surgical correction, if implemented promptly after stabilizing the general condition, can have a relatively good prognosis. Coexisting fetal ileal atresia and gestational diabetes mellitus are rare occurrences, which can make each condition even more difficult to treat.

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.

Primary anastomosis is the preferred surgical approach for proximal intestinal atresia: a retrospective 20-year analysis

PURPOSE

We aimed to compare the outcomes of primary anastomosis (PA) and enterostomy as treatments for intestinal atresia in neonates to identify the factors influencing the choice of modality.

METHODS

We conducted a retrospective single-centre analysis of all neonates with intestinal atresia between 2000 and 2020 and measured the clinical outcomes. We performed logistic regression to identify factors that influenced the choice of surgical approach.

RESULTS

Of 62 intestinal atresia neonates, 71% received PA. There were no significant differences in gestation, gender, age at operation, birth weight, or body weight at operation between the PA and enterostomy groups. PA reoperation was not required for 78% of patients, and the PA group had shorter hospital stays. Complications, operative time, duration on parenteral nutrition, time to full enteral feeding were comparable in both groups. Upon multivariate regression analysis, surgeons favoured PA in proximal atresia [Odds ratio (OR) 38.5, 95% Confidence Interval (CI) 2.558-579] while enterostomy in smaller body size [OR 2.75, CI 0.538-14.02] and lower Apgar score [OR 1.1, CI 0.07-17.8]. Subgroup analysis in these patient groups demonstrated comparable outcomes with both surgical approaches.

CONCLUSION

Both surgical approaches achieved comparable outcomes, but PA was associated with short hospital stays and the avoidance of stoma-related complications, and reoperation was generally not required. This surgical approach was suitable for patients with proximal atresia, but enterostomy remained a sensible choice for patients with smaller body sizes and lower Apgar scores.

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.

Jejunoileal Atresia: A National Cohort Study

Purpose: Jejunoileal atresia (JIA) is a rare disease. We aimed to determine the overall incidence of this malformation and associated malformations in a national cohort. Furthermore, we compared the treatment results of this cohort with the current literature. Methods: Data from the major health insurance company, which covers ~30% of the German population, were analyzed. All patients with ICD-10-Code Q41.1-9 (atresia of jejunum, ileum, other parts and not designated parts of the small bowel) who underwent any surgical procedure for small bowel were analyzed in a 10-year period between 2007 and 2016. Results: A total of 435 patients were included in the study. The incidence was 2.1 per 10,000 live births. The male:female ratio was 1:2. Sixty-four percent were premature, 21% had associated cardiac anomalies, 16% had abdominal wall defects, 7% had urogenital malformations, and 7% had cystic fibrosis. Sixty percent of all patients with jejunoileal atresia, 57% of patients with accompanying abdominal wall defects and 72% of patients with associated cystic fibrosis required ostomy as the initial procedure. In 25% of all patients, only one intestinal operation was coded. In 39% of patients, two operations were coded. Twelve percent of all patients required feeding gastrostomy or jejunostomy. Sixteen percent of all patients presented with liver-related complications, i.e., cholestasis or liver insufficiency. Six patients underwent an intestinal lengthening procedure (2 Bianchi, 4 STEP). In five patients, initial lengthening was performed within 1 year after the first intestinal operation. Mortality until 1 year after initial surgery was 5%. Of those who died, 88% were premature, 34% had cardiac anomalies and 16% had abdominal wall defects. None had cystic fibrosis. Patients with ostomy significantly more often needed operative central venous line or operative feeding tube. Short bowel was coded significantly more often in these patients. Conclusion: Patients with JIA present with low mortality. The rate of ostomies is higher than in literature. To give clinical recommendations for the initial surgical approach, further clinical research is needed.

Analysis of risk factors for unplanned reoperation following primary repair of gastrointestinal disorders in neonates

Background

The aim of our study was to identify the factors associated with unplanned reoperations among neonates who had undergone primary repair of gastrointestinal disorders.

Methods

A retrospective chart review was conducted for neonates who underwent primary gastrointestinal surgery between July 2018 and September 2020. The neonates were divided into two cohort, depending on whether they had an unplanned reoperation. The primary outcome was the occurrence of unplanned reoperation. The risk factors that associated the occurrence of unplanned reoperation were examined.

Main results

Two hundred ninety-six neonates fulfilled the eligibility criteria. The incidence of unplanned reoperation was 9.8%. Analyses of all patients with respect of developing unplanned reoperation showed that the length of operative time was an independent risk factor [Odds Ratio 1.02; 95% confidence interval 1.00, 1.04; p = 0.03]. Patients with unplanned reoperation had a longer postoperative hospital length-of-stay [19.9 ± 14.7 vs. 44.1 ± 32.1 days; p<0.01].

Conclusion

The current study is the first analysis of risk factors associated with an unplanned reoperation in neonates undergoing primary repair of gastrointestinal disorders. The length of operative time is the only risk factor for an unplanned reoperation, and the unplanned reoperation can directly prolong the postoperative hospital length-of-stay.

How can we improve perinatal care in isolated multiple intestinal atresia? A retrospective study with a 30-year literature review

INTRODUCTION

Multiple intestinal atresia (MIA) is a rare cause of neonatal intestinal obstruction. To provide an overview of the current prenatal, surgical, and nutritional management of MIA, we report our experience and a literature review of papers published after 1990.

METHODS

All cases of isolated MIA (non-hereditary, not associated with apple-peel syndrome or gastroschisis) treated at our institution between 2005 and 2016 were reviewed and compared with cases found in the literature.

RESULTS

Seven patients were prenatally suspected of having intestinal obstruction and were postnatally diagnosed with MIA, with a mean 1.7 (1-2) resections-anastomoses (RA) and 6 (1-10) strictureplasties performed, resulting in a mean resected bowel length of 15.1cm (15-25 cm). Median time to full oral feed was 46 days (14-626 days). All patients were alive and none had orality disorder after a mean follow-up of 3.1 years (0.2-8.1 years). Three surgical strategies were found in the literature review: multiple RA (68%, 34/50) including Santulli's technique in four of 34 (12%) and anastomoses over a transanastomotic tube (32%, 16/50), with a 98% survival rate, and short-bowel syndrome for only two patients.

CONCLUSION

Bowel-sparing surgery and appropriate medical management are key to ensuring a favorable nutritional and gastrointestinal outcome and a good prognosis. Prenatal assessment and standardization of the surgical course of treatment remain challenging.

Predictive Factors for Postoperative Outcome in Children with Jejunoileal Atresia

Background  Jejunoileal atresia is a relatively rare congenital gastrointestinal requiring surgery and long postoperative care. The postoperative outcome is affected by many factors and this study focuses on finding predictors for time to full enteral feeding, length of hospital stay (LOH), and postoperative complications. Methods  This was a retrospective study of all children operated for isolated jejunoileal atresia between 2001 and 2017 at a tertiary center of pediatric surgery. Independent variables regarding demographical-, operative-, and postoperative data were abstracted. Primary outcome was time to full enteral feeding, LOH, and postoperative complications in terms of reoperation or central line complication. Any significant variables from the univariate analysis were further analyzed with logistic regression and presented as odds ratio with 95% confidence interval. Results  After exclusion because of concomitant gastroschisis ( n  = 1), and death before discharge ( n  = 2), 47 patients were further analyzed (49% boys, 53% premature). No significant differences could be seen in the univariate analysis between children with short and long time (median > 17 days) to full enteral nutrition. Patients with longer LOH (median >32 days) had significantly lower birth weight compared with those with shorter LOH; median 2,550 g versus 2,980 g ( p  = 0.04). Patients with a central line complication had significantly longer median time to full enteral feeding (median 27 vs. 12 days, p  = 0.03), and significantly longer median LOH (median 43 vs. 21 days, p  = 0.03), but these parameters were not significant in a multivariate analysis. No significant results were found regarding reoperation. Conclusion  Low birth weight seems associated with an increased LOH in children operated on for jejunoileal atresia, and central line complications seem related to the duration with central line in this group. The small cohort may constitute a power problem in this study and further research regarding the included variables may reveal more potential predictors for the postoperative outcome.

Jejunal Occlusion Caused by Heterotopic Gastric and Duodenal Mucosa: A Late Complication of a Complex Intestinal Malformation

We report a rare case of late complication of a complex intestinal malformation. At day 1 of life, a baby girl underwent resection of an atretic jejunal segment, associated with an enteric duplication harboring foci of gastric and duodenal heterotopia. After an asymptomatic period of 19 years, the patient presented with acute bowel obstruction. Recurrence of the jejunal occlusion at the previous anastomotic site was caused by mucosa hyperplasia in association with heterotopic gastric and duodenal tissue. A Wnt/β-catenin pathway deregulation was hypothesized but not confirmed by CTNNB1 exon 3 mutation analysis. This case illustrates a rare association of 3 pathologies-namely, intestinal atresia, enteric duplication, and heterotopia, with a late-occurring acute complication.

Early Reoperations after Primary Repair of Jejunoileal Atresia in Newborns

Aim: To review nine-year experience in managing jejuno-ileal atresia (JIA) by primary resection and anastomosis and identify factors associated with reoperations.

Methods: From April 2006 to May 2015, all consecutive neonates who underwent bowel resection and primary anastomosis for JIA were analyzed retrospectively. Patients with temporary enterostomy were excluded. Patient demographics, types of atresia, surgical techniques, need for reoperations, and long-term outcomes were investigated.

Results: A total of forty-three neonates were included, in which nineteen (44.2%) of them were preterm and fourteen (32.6%) were of low birth weight. Thirteen patients (30.2%) had jejunal atresia whereas thirty patients (69.8%) had ileal atresia. Volvulus, intussusception and meconium peritonitis were noted in 12, 8, and13 patients, respectively. Eight patients (18.6%) had short bowel syndrome after operation. Ten patients (23.3%) required reoperations from 18 days to 4 months after the initial surgery due to anastomotic stricture (n=1), adhesive intestinal obstruction (n=1), small bowel perforation (n=2) and functional obstruction (n=6). Prematurity and low birth weight were associated with functional obstruction leading to reoperation (p=0.04 and 0.01 respectively). The overall long-term survival was 97.7%. All surviving patients achieved enteral autonomy and catch-up growth at a median follow-up of 4.7 years.

Conclusion: Long-term survival of JIA after primary resection and anastomosis are excellent. However, patients have substantial risk of early reoperations to tackle intraabdominal complications.

Small Bowel Congenital Anomalies: a Review and Update

The small intestine is a complex organ system that is vital to the life of the individual. There are a number of congenital anomalies that occur and present most commonly in infancy; however, some may not present until adulthood. Most congenital anomalies of the small intestine will present with obstructive symptoms while some may present with vomiting, abdominal pain, and/or gastrointestinal bleeding. Various radiologic procedures can aid in the diagnosis of these lesions that vary depending on the particular anomaly. Definitive therapy for these congenial anomalies is surgical, and in some cases, surgery needs to be performed urgently. The overall prognosis of congenital anomalies of the small intestine is very good and has improved with improved medical management and the advent of newer surgical modalities. The congenital anomalies of the small intestine reviewed in this article include malrotation, Meckel's diverticulum, duodenal web, duodenal atresia, jejunoileal atresia, and duplications.

Accuracy of prenatal ultrasound in detecting jejunal and ileal atresia: systematic review and meta-analysis

OBJECTIVE

The accuracy of prenatal ultrasound examination in detecting jejunal and ileal atresia has been reported in the literature to be highly variable, at 25-90%. The aim of this systematic review was to evaluate the accuracy of prenatal ultrasound in detecting non-duodenal small bowel atresia (ND-SBA).

METHODS

MEDLINE, EMBASE and The Cochrane Library, including The Cochrane Database of Systematic Reviews (CDSR), Database of Abstracts of Reviews of Effects (DARE) and The Cochrane Central Register of Controlled Trials (CENTRAL), were searched electronically. The overall detection rate of jejunal or ileal atresia using ultrasound was reported. The accuracy of using polyhydramnios and dilated loops of bowel as diagnostic signs was also explored.

RESULTS

Sixteen studies involving 640 fetuses were included in this review. The detection rate of ND-SBA by prenatal ultrasound was highly variable, with values ranging from 10 to 100%, with an overall prediction of 50.6% (95% CI, 38.0-63.2%). When analyzed separately, the detection rates of jejunal and ileal atresia were 66.3%, (95% CI, 33.9-91.8%) and 25.9% (95% CI, 4.0-58.0%), respectively. Both dilated loops of bowel and polyhydramnios as diagnostic signs for ND-SBA provided a low overall detection rate.

CONCLUSIONS

The diagnostic performance of prenatal ultrasound in identifying ND-SBA is extremely variable. Large studies are needed in order to identify objective and combined criteria for the diagnosis of these anomalies.

Malrotation and intestinal atresias

This review encompasses four congenital conditions which present with symptoms of bowel obstruction in the neonatal period. The antenatal and postnatal features of malrotation, jejuno-ileal atresia, duodenal atresia and colonic atresia are discussed. Each condition is outlined including the classification, epidemiology, aetiology and presentation, and a summary of the surgical management is described.
