Adult rectosigmoid junction intussusception presenting with rectal prolapse

Incarcerated Prolapsed Sigmoid Intussusception Presenting as Rectal Prolapse Without a Lead Point

“…Most reports state that 70%–90% of cases have an identifiable source, a lead point, with 40%–50% being due to a malignancy and only 10% being idiopathic 4. There are published case reports discussing sigmoid intussuception through the rectum due to lipoma or malignancy 5–13. Our case report adds to the current literature by reporting on two cases that were idiopathic in nature without lead point/malignancy.…”

A rare case of sigmoid intussusception. A case report

“…A rectal intussusception can mimic a rectal prolapse and it can be quite difficult to differentiate between the two based on history alone [ 4 ]. On physical examination, a leading point lesion can be found on the protruding mass in the case of intussusceptions, which does not occur in cases of rectal prolapses [ 4 ].…”

“…Patients with intussusception can present with very chronic and nonspecific symptoms such as abdominal pain, nausea, vomiting, constipation and gastrointestinal bleeding [ 4 ]. Rectal prolapse is an even more rare presentation of intussusception [ 4 ] and our case report will present one such case.…”

“…Patients with intussusception can present with very chronic and nonspecific symptoms such as abdominal pain, nausea, vomiting, constipation and gastrointestinal bleeding [ 4 ]. Rectal prolapse is an even more rare presentation of intussusception [ 4 ] and our case report will present one such case. This becomes important when a rectal prolapse is actually mimicking a malignancy and hence timely diagnosis and intervention becomes challenging.…”

An uncommon diagnosis of a common presentation of mass per rectum

“…Rectal prolapse is protrusion of rectal mucosa (mucosal prolapse) or the entire rectum (full thickness prolapse) through the anal opening. Rectal prolapse as a first presentation of underlying malignancy has an overall incidence of 0.25 to 0.4%) [ 8 ], with only 9 cases being reported in the literature [ 9 ]. Prolapse of a proximal segment of bowel masquerading as a full-thickness rectal prolapse is even less frequently seen.…”
