Abstract
Aims
A case report of a splenic rupture resulting from an obstructed sigmoid cancer in a 62 year old patient. Patient presented with colorectal cancer symptoms, suddenly developed severe abdominal pain and hypotensive shock, a diagnosis of splenic rupture resulted in early surgical intervention (splenectomy, Hartman’s resection).
Conclusion
Atypical presentations could have adversely delayed the diagnosis of splenic rupture. Serial clinical assessments and observations, supported by serological and radiological tests is crucial in the management and can lead to early surgical intervention in an unstable patient. Prompt resuscitation and imaging facilitated an early diagnoses and surgical management.
CT scan showed large volume of haemo-peritoneum with evidence of splenic rupture. Spleen histopathology was generally normal, with a potential of angiomatosis, but no metastatic disease.
Emergency colorectal cancers still accounts for 20% of all colorectal cancers. Splenic rupture is a rare complication in an obstructed colorectal cancer, but under-reported. Traumatic splenic rupture accounts for approximately 75 % whilst atraumatic represents less than 12 %. Splenic rupture can occur in the presence of splenic neoplasms as either primary or secondary disease.
This is caused by excessive traction on the spleno-colic ligament causing avulsion and tear of splenic capsule, heamatoma and subsequent spleen rupture. This can be considered as internal trauma to a viscus organ. Awareness of such a mechanism of splenic rupture in an obstructed sigmoid cancer can lead to an earlier diagnosis and get better outcomes, in the absence of trauma.
