Norwich paediatric triad: malrotation, intussusception and small intestinal lymphoma

Delayed Presentation of Malrotation after Infancy: A Systematic Review Based on Clinical Presentations, Associated Anomalies, Diagnosis, and Management

Need and Purpose of Review

Approximately 75% of patients with classic malrotation and midgut volvulus present in neonatal age-group; another 15% may present up to one year. In these, the diagnosis is made because of typical presentation. However, there are many cases in which malrotation has been detected after infancy. In-spite of the variable case reports and studies in literature, there is no specific data on the incidence of malrotation after infancy, its presentation and management guidelines. With this systematic review, we aim to coalesce these findings from various individual case reports and studies.

Methods Used for Collecting and Analysing Data

This systematic review was performed as per the PRISMA (preferred reporting items for systematic review and meta-analyses) guidelines. The authors conducted thorough searches in databases like PubMed/MEDLINE, SCOPUS, Google Scholar and Web of Science for relevant articles. Studies were reviewed for clinical presentation and outcome for malrotation diagnosed beyond infancy.

Main Conclusions

Clinical presentation of malrotation after infancy can be acute as well as chronic; acute presentation being common under 2 years of age and chronic symptoms present as age increases. Sudden onset of abdominal pain and bilious vomiting are commonest acute symptoms and intermittent episodes of recurring vague abdominal pain associated with vomiting and diarrhoea are the commonest chronic symptoms. The diagnostic modalities vary from UGI Contrast series to USG with colour Doppler and CECT scan. Management is operative open as well as laparoscopic Ladd's procedure is being favoured.

Recurrent lymphoma presenting as painless, chronic intussusception: A case report

BACKGROUND

The clinical presentation of acute lymphoblastic lymphoma is highly varied. While prognosis is good, recurrence of disease can occur. Gastrointestinal relapse, including intussusception, is well-described but the absence of abdominal pain in this setting is rare.

CASE SUMMARY

We report a 13-year-old male with B-cell precursor acute lymphoblastic leukemia in remission presenting with anemia and weight loss. Examination was significant for absence of abdominal pain, but a stool sample was positive for occult blood. Pan-endoscopy was performed with colonoscopy revealing a mass filling the colonic lumen. Biopsy of the mass confirmed recurrence of recurrent B-cell lymphoma. Computed tomography scan revealed ileocolic intussusception resulting from the tumor. This case is unusual in that the patient had no abdominal pain despite the presence of intussusception.

CONCLUSION

While intestinal involvement with lymphoma has been well described in the literature, presentation as painless intussusception has not been reported. This case report highlights the wide spectrum of clinical manifestations of recurrent B-cell lymphoma involving the gastrointestinal tract, in particular the near absence of symptoms despite the finding of intussusception.
