Surgical management and outcomes of rare adult ıntussusception: A single tertiary center experience

Aim: Intussusception in adults is a rare condition.Since it is usually associated with an underlying intestinal pathology, surgical treatment is typically required.This study aims to evaluate cases of intussusception managed at a tertiary care center.Material and Methods: This retrospective study was conducted in the Department of General Surgery at Kocaeli University Faculty of Medicine.Patients who underwent surgery for intussusception between January 1, 2015, and January 1, 2025, were included in the study.The cases were categorized into enteroenteric, ileocolic, and colocolic subgroups and compared in terms of clinical and pathological data.Demographic and clinical characteristics of the patients were obtained through a review of medical records.Results: A total of 12 patients underwent surgery for intussusception.The mean age of the patients was 45.4 years.Of these, 9 were classified as having enteroenteric, 2 ileocolic, and 1 colocolic intussusception.The most common presenting symptom was abdominal pain (73.3%).The most frequent etiology was small bowel tumors (33.3%).Segmental small bowel resection was the most commonly performed surgical procedure (41.7%).Histopathological evaluation revealed submucosal lipoma as the most common finding (22.2%).Among the ileocolic cases, one patient was diagnosed with adenocarcinoma.Discussion: Surgical resection of the affected bowel segment is the mainstay of treatment for intussusception in adults.Although benign etiologies are more commonly observed in small bowel cases, it is important to note that malignancies may be present, particularly in ileocolic and colocolic types.Therefore, surgical procedures should be performed with careful consideration of this possibility.
