However, VP shunt trapped on the serosal side of colon cancer is rare, and there is no clear treatment strategy.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 72-year-old man presented with a 1-month history of constipation, diarrhea, and weight loss. His medical history consisted of subarachnoid hemorrhage and hydrocephalus 13 years earlier, for which endovascular coiling and VP shunting were performed. Colonoscopy showed a sigmoid mass, the biopsy of which revealed tubular adenocarcinoma. Computed tomography demonstrated circumferential wall thickening of the sigmoid colon without evidence of metastasis, with the lesion surrounding the tip of the VP shunt. He underwent laparoscopic surgery for sigmoid colon cancer. Unexpectedly, the VP shunt was trapped in the serous side of the tumor, and both the shunt and tumor were excised. Microscopic examination revealed inflammation and fibrosis, but no cancer cells were found in the serosa surrounding the embedded VP shunt tip.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Bowel perforation due to a VP shunt is a rare but emergency condition. If the perforation occurs around cancerous tissue, it must be handled with extreme care; excising the shunt along with the tumor may be the safest treatment method. Clinicians need to pay attention to the end of the VP shunt when performing surgery for patients with cancer and VP shunt.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_444_2022","type":"journal-article","created":{"date-parts":[[2022,8,5]],"date-time":"2022-08-05T11:05:55Z","timestamp":1659697555000},"page":"339","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Unexpected findings during colon cancer surgery: A rare complication of ventriculoperitoneal shunt"],"prefix":"10.25259","volume":"13","author":[{"given":"Naoki","family":"Ishimaru","sequence":"first","affiliation":[{"name":"Department of Surgery, Suwa Central Hospital, Chino,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirohisa","family":"Fujikawa","sequence":"additional","affiliation":[{"name":"Department of Medical Education Studies, International Research Center for Medical Education, Graduate School of Medicine, The University of Tokyo, Tokyo,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirohisa","family":"Fujikawa","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Suwa Central Hospital, Chino, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuya","family":"Niwa","sequence":"additional","affiliation":[{"name":"Department of Surgery, Suwa Central Hospital, Chino,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2022,8,5]]},"reference":[{"key":"10.25259\/SNI_444_2022\/ref-1","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1016\/S0090-3019(97)00014-1","article-title":"Colonic perforation by ventriculoperitoneal shunt tubing: A case of suspected silicone allergy","volume":"49","author":"Brownlee","year":"1998","journal-title":"Surg Neurol"},{"key":"10.25259\/SNI_444_2022\/ref-2","doi-asserted-by":"crossref","first-page":"66","DOI":"10.1016\/j.inat.2018.04.004","article-title":"Ventriculoperitoneal shunt complications: A review","volume":"13","author":"Paff","year":"2018","journal-title":"Interdiscip Neurosurg"},{"key":"10.25259\/SNI_444_2022\/ref-3","doi-asserted-by":"crossref","first-page":"36","DOI":"10.3171\/2014.11.PEDS14347","article-title":"Ventriculoperitoneal shunt perforations of the gastrointestinal tract","volume":"16","author":"Thiong\u2019o","year":"2015","journal-title":"J Neurosurg Pediatr"}],"container-title":["Surgical Neurology International"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/surgicalneurologyint.com\/unexpected-findings-during-colon-cancer-surgery-a-rare-complication-of-ventriculoperitoneal-shunt\/","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/unexpected-findings-during-colon-cancer-surgery-a-rare-complication-of-ventriculoperitoneal-shunt\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,8,5]],"date-time":"2022-08-05T11:05:59Z","timestamp":1659697559000},"score":1,"resource":{"primary":{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/unexpected-findings-during-colon-cancer-surgery-a-rare-complication-of-ventriculoperitoneal-shunt\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,8,5]]},"references-count":3,"alternative-id":["10.25259\/SNI_444_2022"],"URL":"https:\/\/doi.org\/10.25259\/sni_444_2022","relation":{},"ISSN":["2152-7806"],"issn-type":[{"value":"2152-7806","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,8,5]]},"article-number":"339"}}
