Colosplenic Fistula: a Highly Unusual Colonic Fistula

Abstract

Internal fistulization of the colon to other organs, such as the urinary bladder, vagina, or small bowel is a relatively common complication associated with inflammatory diseases such as diverticulitis, Crohn disease, as well as neoplasia such as colorectal cancer or lymphoma. However, fistulization of the colon to the spleen is an exceedingly rare condition described by few in the literature.

Colon Cancer with Colosplenic Fistula

“…Like other enteric fistulas, they arise from infectious, neoplastic, and inflammatory processes such as diverticulitis, colorectal cancer, lymphoma, pancreatitis, splenic abscesses and, most commonly, fistulizing Crohn's Disease [1,2]. Colosplenic fistulas require cross-sectional imaging for diagnosis and further management [3].…”

Colosplenic fistula as a complication of splenic abscess

“…Carpal tunnel syndrome (CTS) is the most frequent compressive neuropathy in the upper limb, with an incidence of 1% of the general population. 1 Satisfactory out are achieved for the majority after decompression. A small proportion of individuals (3-20%) have persistent, recurrent or new symptoms following carpal tunnel release.…”

“…A small proportion of individuals (3-20%) have persistent, recurrent or new symptoms following carpal tunnel release. 1,2 Reoperation rates have been reported as up to 12%. 1 We report a 61-year-old female patient, referred by an orthopaedic unit for a second opinion on the management of her recurrent right CTS.…”

“…1,2 Reoperation rates have been reported as up to 12%. 1 We report a 61-year-old female patient, referred by an orthopaedic unit for a second opinion on the management of her recurrent right CTS. Previously, she had multiple revision procedures involving median nerve release, scar debulking and palmaris longus excision.…”

“…Colosplenic fistula is a very rare condition and there are only several reports in the literature. 1,2 It has been suggested that in patients with splenic lymphoma, invasion to the gastric wall causes widespread necrosis resulting in fistula formation. 3 In our case, there was just multinuclear cell infiltration in the serosa suggesting the presence of an inflammatory process compatible with splenic abscesses.…”
