Ongom and colleagues describe an ileocolic intussusception in a 32 year-old female who initially reported colicky abdominal pain and vomiting, find more associated with straining during defecation and incomplete evacuation of her rectum. Over the next two weeks prior to presentation, she noted continued colicky abdominal pain, bloody-mucoid discharge and a reducible mass protruding from her anus. On physical examination, an abdominal mass
was palpated in the umbilical region and rectal mass noted 3cm proximal to the anal verge. Abdominal ultrasound confirmed the presumptive diagnosis of prolapsed intussusception with partial bowel obstruction. The mass was only able to be partially reduced in a distal to proximal direction and a subsequent right hemicolectomy was performed. The authors noted absence of hepatocolic and splenocolic ligaments and lack of
retroperitoneal fixation. Although pathology was negative for neoplasm, they theorized the lack of zygosis with persistent ascending and descending mesocolons helped to enable this presentation [3]. Furthermore, persistent descending mesocolons have been noted in previous reports as the etiology of colonic volvulus [8, 9] and internal hernia [10]. Thus, two principle factors are causative in this case presentation of total ileocolic intussusception with rectal prolapse. The first being the lead point pathology of the villous adenoma, and the second being the increased colonic mobility associated with lack of zygosis. Conclusions Intussusception is an uncommon etiology of bowel obstruction in adults and can be Small molecule library research buy attributed to benign and malignant pathologies. Despite advancements in diagnostic accuracy, a high index of suspicion and clinical acumen is required for timely diagnosis and therapy of this condition in adults. Total ileocolic intussusception with rectal prolapse, found at the end of the adult intussusception spectrum, may be predisposed by an embryological variant lacking zygosis. For the acute care surgeon who may encounter this rare Sapanisertib nmr surgical emergency,
the diagnosis should be considered in the differential GNA12 of a prolapsing rectal mass and be expeditiously managed to optimize patient outcomes. Assessing for the absence of zygosis should be an adjunct to the operative procedure as well.
