EVOLUTIVE PECULIARITIES OF AN ILEO-CECAL VALVE TUMOR: CASE REPORT

Introduction: Tumors of ileo-caecal valve are most clinically manifested either through transit disorders or anemic syndrome. The 88-year-old patient is admitted for abdominal pain in the left flank, vomiting, asthenia and lack of intestinal transit for faeces, with a progressive onset of one week. Clinical examination: generalized affected state, wide abdomen, painful left flank and hypochondrium, lack of intestinal transit and pallor. Paraclinic: severe hypochromic microchrome anemia (hemoglobin: 5.8 g / dl). Plain radiography: hydro-aeric levels in the left hypochondrium. Abdominal CT: ileo-colic intussusception that completely occupies the ascending colon to the hepatic flexure, with no visible tumoral lesions. After hydroelectrolytic and hemodynamic balancing with restoration of intestinal transit, colonoscopy is performed: 5 cm ulcer-vegetative tumor formation at the ileo-caecal valve level - biopsy with histopathological examination: moderately differentiated adenocarcinoma. Patient refuses surgery. After 3 weeks, the patient returns to the clinic for the recurrence of digestive symptoms and emergency surgery is performed: laparotomy by median suprasubombilical incision, finding: ileo-ceco-appendico-colic invagination up to the middle third of the transverse colon, defective attachment of ascending colon, ileum dilated with thick wall. The invagination is reduced, the tumor formation is discovered. Right hemicolectomy with ileotransversoanastomosis is performed. Postoperatively, the patient shows a simple evolution with discharge of the 9th postoperative day. Conclusions: The ileocolic invagination in adults is most often the appearance of a tumor located on mobile segments of the intestine. The right colon invagination is possible when there is a defect of acolation, anatomical peculiarity encountered in the presented case.
