Abstract:
Objective To identify the risk factors for functional delayed gastric emptying (FDGE) after retroperitoneal tumor resection.
Methods Sixty-seven patients with postoperative FDGE after retroperitoneal tumor resection from September 2017 to December 2022 admited in Peking University International Hospital were included in the observation group, and 836 normal patients who underwent retroperitoneal tumor resection during the same period were included in the control group. Medical histories and clinical treatment data were obtained for each group and compared to identify the risk factors for FDGE after retroperitoneal tumor resection.
Results The overall incidence of postoperative FDGE was 7.42%. Factors that were significantly elevated (P<0.05) in the observation group relative to the control group included adverse mental factors (37.31%), preoperative digestive tract obstruction (41.79%), postoperative abdominal cavity complications (79.10%), diabetes (29.86%), average age of (61.85±6.11) years, and blood loss (1011.94±507.30) mL. Pre-and post-surgery albumin levels (38.22±3.75) g/L and (30.22±3.36) g/L, respectively were significantly reduced (P<0.05) in the observation group compared to the control group. Risk factor analyses revealed that advanced age, diabetes, preoperative digestive tract obstruction, intraoperative blood loss, perioperative albumin level, postoperative abdominal cavity complications, and adverse mental factors were correlated with postoperative FDGE.
Conclusions Diverse factors could impact the risk of FDGE after retroperitoneal tumor resection. Patients should be accurately evaluated; reasonable and detailed prevention and treatment plans should be developed.
