Diagnosis and management of intestinal rotational abnormalities with or without volvulus in the pediatric population

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.

Intestinal Malrotation in Children: Clinical Presentation and Outcomes

INTRODUCTION

 Intestinal malrotation (IM) is characterized by abnormal intestinal rotation and fixation predisposing to a risk of midgut volvulus. The aim of this study was to describe the clinical presentation and outcome of IM from birth through childhood.

MATERIALS AND METHODS

 This was a retrospective study of children with IM managed at a single center between 1983 and 2016. Data were retrieved from medical records and analyzed.

RESULTS

 Three hundred nineteen patients were eligible for the study. Using strict inclusion and exclusion criteria, 138 children were included. Vomiting was the most common symptom up to 5 years of age. At 6 to 15 years of age, abdominal pain was the predominant symptom. One hundred twenty-five patients underwent a Ladd's procedure and of 124 patients with available data, 20% had a postoperative complication (Clavien-Dindo IIIb-V) within 30 days. The odds ratio to develop postoperative complications was significantly increased in extremely preterm patients (p = 0.001) and in patients with severely affected intestinal circulation (p = 0.006). Two patients had intestinal failure due to midgut loss after midgut volvulus, one of whom needed intestinal transplantation. Four patients, all extremely preterm, died related to the surgical procedure. In addition, seven patients died of reasons not related to IM. Fourteen patients (11%) had adhesive bowel obstruction and one patient had recurrent midgut volvulus requiring surgical treatment.

CONCLUSIONS

 IM presents with different symptoms through childhood depending on age. Postoperative complications are common after Ladd's procedure, particularly among extremely preterm infants and patients with severely affected circulation caused by midgut volvulus.

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.

Assessment of care timelines in intestinal malrotation with volvulus: A retrospective chart review

BACKGROUND

Patients with intestinal malrotation with volvulus (MWV) may suffer bowel ischemia, which can be correlated with the timing of surgical intervention. The purpose of this study was to identify and assess time-blocks in the care of patients from initial physician assessment (IPA) to surgical intervention to highlight potential opportunities for improvement.

METHODS

Retrospective chart review of patients with MWV presenting to McMaster Children's Hospital between January 1st, 2000 and December 31st, 2020 (n = 31). Demographic data and time-blocks of care were identified and analyzed (p < 0.05 considered significant). All times were reported as medians.

RESULTS

22 males (71%) and 9 females (29%) were identified; median age was 9.8 d. IPA to incision was 10.7hrs and surgical consult to incision was 3.4hrs. Time to incision for patients <1 y was not significantly different than those >1 y (10.5hrs vs 10.7hrs, p = 0.737). The use of ultrasound did not significantly affect time to incision (7.9hrs vs 12.0hrs, p = 0.128). For patients requiring resection or having pan-necrosis there was no significant difference in time from IPA (10.9hrs vs 10.5hrs, p = 0.238) or surgical consult to incision (4.0hrs vs 3.3hrs, p = 0.808).

CONCLUSION

Time from IPA to surgical consult and time from surgical consult to surgical intervention represented the largest proportions of time. Age, use of ultrasound, and need for resection or having pan-necrosis did not significantly affect the time to incision. This data may be used to inform opportunities for expediting the management of patients with MWV once they have presented to a physician.
