Abstract
BACKGROUND
Intussusception in adults is a rare condition characterized by a low incidence, which complicates the establishment of standardized management protocols unlike those readily available for pediatric cases. This study presents a case series from our institution alongside a systematic review of existing literature. The objective is to delineate effective management strategies for adult intussusception.
METHODS
A systematic search of databases was conducted covering the period from January 2000 to May 2024. The study focused on adult patients diagnosed with intussusception either pre-operatively or intraoperatively and managed with either surgical intervention or conservative methods. The analysis also included retrospective review of patient records from our institution, specifically targeting individuals over 18 years of age, to determine the predominant types of intussusception and identify any pathological lead points associated with these cases.
RESULTS
In our study, a total of 1,902 patients were included from 59 selected articles, with a mean age of 52.13 ± 14.95 years. Among them, 1,920 intussusceptions were diagnosed, with 98.3% of cases identified preoperatively. Computed tomography (CT) scan was the primary diagnostic modality used in 88.5% of cases. Abdominal pain was the predominant presenting symptom, observed in 86.23% of cases. Only 29 out of 1,920 cases underwent attempted reduction, while the majority required surgical resection due to the high incidence of malignancy in adult cases. The most common type of intussusception identified was colocolic (16.82%), followed by enteric (13.28%), ileocolic (4.89%), and ileocaecal (0.78%) types. A pathological lead point was observed in 302 out of 673 patients (44.84%), with a notably higher frequency of malignancy associated with colocolic intussusception.
CONCLUSION
Surgical management remains the cornerstone in treating adult intussusception, particularly in cases involving the colocolic type, where there is a significant risk of underlying malignancy. Attempts at reduction are generally avoided due to the potential risk of tumor dissemination, which could adversely impact patient outcomes. Contrast-enhanced computed tomography (CECT) of the abdomen is pivotal for accurately diagnosing intussusceptions and guiding appropriate management strategies. It is imperative to adhere strictly to oncological principles during surgical interventions to ensure optimal patient care and outcomes.
