Background:
Delayed gastric emptying (DGE) is an underrecognized but clinically impactful complication following multivisceral resection (MVR) for retroperitoneal sarcoma (RPS). This study aimed to determine the incidence, risk factors, and postoperative morbidity of clinically significant DGE in a Latin American tertiary referral sarcoma center.
Methods:
We conducted a retrospective cohort study of adult patients with primary or recurrent RPS who underwent MVR between January 2020 and December 2024. DGE was defined and graded according to ISGPS criteria, with grades B-C considered clinically significant. Multivariable logistic regression identified independent predictors for DGE. Clinical outcomes were compared by DGE status.
Results:
Among 142 patients who underwent MVR, the incidence of clinically significant DGE was 8.6 %. Independent risk factors included tumor size >22 cm (OR 2.25; 95 % CI 1.12-4.50; p = 0.023), dedifferentiated liposarcoma histology (OR 3.52; 95 % CI 1.12-11.01; p = 0.031), and multifocal disease (OR 2.78; 95 % CI 1.03-7.49; p = 0.044). DGE was associated with a prolonged hospital stay (22 vs. 10.5 days, p < 0.001) and a higher rate of ICU admission (9.3 % vs. 2.7 %, p = 0.034). No significant associations were found with major complications or reoperation.
Conclusions:
Clinically significant DGE is an infrequent but high-impact complication after MVR for RPS. Tumor-related features such as large size, high-grade histology, and multifocality contribute to its development. Early identification and standardized perioperative strategies may help reduce the incidence and clinical burden of this condition. These findings provide essential data from a historically underrepresented region and support efforts to optimize postoperative recovery in complex sarcoma surgery.
