Non-operative management of a rare diagnosis of splenic torsion in a child with a history of giant omphalocele: a case report and literature review

Surgical Management of a Volvulus of a Wandering Spleen Associated with a Volvulus of the Small Intestine

Introduction

A wandering spleen is a rare anatomical condition characterized by a free-floating splenic tissue that is not located in its normal position in the left upper quadrant. This condition is usually asymptomatic but can also manifest itself with volvulus of the spleen and consequent infarction and necrosis of the parenchyma, requiring an urgent surgical management. Additionally, a wandering spleen can be associated with other contemporaneous anatomical anomalies. Case Presentation. We report a case of a 21-year-old woman, admitted to our hospital for intense abdominal pain and vomiting. A CT scan revealed a wandering spleen in the mesogastric area with the spleen torted on its axis, associated with a volvulus of the small intestine. Abdominal exploration revealed a macroscopically normal free-floating spleen attached to an abnormally long vascular pedicle. The management of the wandering spleen was conservative, and a splenopexy was performed.

Conclusions

The torsion of the wandering spleen constitutes an infrequent but life-threatening abdominal emergency. The diagnosis of the wandering spleen is frequently challenging since clinical findings are usually not specific. Imaging such as computed tomography scan plays an important role in the differential diagnosis pathway. Treatment should be planned according to the splenic parenchyma conditions. Splenectomy is indicated when massive infarction and thrombosis of splenic vessels have occurred. When splenic parenchyma is not compromised, it is preferred to perform a conservative surgical technique, such as splenopexy, in order to avoid postsplenectomy complications.

Challenge of diagnosing splenic torsion in a paediatric patient with gastroschisis

Gastroschisis is an uncommon congenital defect of the abdominal wall resulting in intestinal prolapse, most commonly associated with short gut syndrome or bowel obstruction. Wandering spleen, movement of the spleen due to the underdevelopment of splenic ligaments, has a prevalence of 0.25% and is asymptomatic in 15% of paediatric cases. An 11-year-old patient, admitted with a history of gastroschisis repaired at birth, presents with 18 months of intermittent, worsening abdominal pain. Imaging demonstrated splenomegaly and tortuosity of the splenic vein with abnormal positioning of the superior mesenteric artery and vein. The patient was found to have a wandering spleen with subacute splenic infarct secondary to splenic torsion, necessitating emergent surgical intervention. This patient experienced an extremely rare complication of gastroschisis that has not previously been reported. This complication is caused by a lack of appropriate abdominal fixation points for the spleen.

Case Report: Conservative Non-operative Management of a Neonate With Torted Wandering Spleen

BACKGROUND

The management of wandering spleen (WS) with torsion, a rare pathological condition, is currently unclear. Most patients with this disorder are treated with surgical interventions, such as splenectomy or splenopexy.

CASE PRESENTATION

A newborn female presented with low hemoglobin (10.8 mg/L) and high total serum bilirubin (193 μmol/L) at 3 h of life. A palpable mass was observed during her physical examination, and a magnetic resonance imaging scan of the abdomen confirmed the presence of an infarcted WS with torsion. Upon conservative management with oral antibiotic prophylaxis, careful observation, and repeated follow-ups, the infant remained clinically stable. At 2 years of age, she had normal complete blood count, and a repeat technetium study revealed two splenunculi/splenules in the splenic bed.

CONCLUSION

Most patients with WS are treated surgically with splenectomy or splenopexy. Non-operative management may be a feasible treatment option in select cases with infarcted WS and may allow the natural process of autosplenectomy to occur.

Torsion of a Wandering Spleen Managed Conservatively: Rare and Interesting

Wandering spleen is a rare pathology. A 2-year-old child with abdominal pain was diagnosed to have a torted, avascular wandering spleen. On conservative management, she remains well with no radiological evidence of the spleen. Splenic torsion usually warrants surgery. Nonoperative management in selected cases allows the natural process of autosplenectomy.
