Early readmission after adrenalectomy for pheochromocytoma. A retrospective study
摘要
Adrenalectomy for pheochromocytoma (PHEO) presents a significant challenge due to the high incidence of early hospital readmission (ER). This study evaluated the incidence and risk factors of ER for PHEO within 30 days of adrenalectomy.
MethodsA retrospective analysis of 346 patients > 18 years with unilateral PHEO who underwent adrenalectomy between September 2012 and September 2024. The patients were categorised into ER (n = 49) and no ER (n = 297) groups. Logistic regression analyses were performed to predict risk factors for ER.
ResultsThe most common causes of ER were postoperative maintained hypotension (42.9%), bleeding (6.1%), ileus (24.5%), wound infection (4.1%), hyperkalemia (8.2%), pneumonia (2%), intra-abdominal abscess (2%), acute MI (4.1%), and colonic injury (6.1%). Most postoperative complications were Clavien-Dindo grade II (n = 40, 81.6%). Two perioperative deaths (4%) occurred in the ER group. Logistic regression showed that low body mass index (OR 0.849, 95% CI, 0.748–0.964; p = 0.012), tumor size < 5 cm (OR 0.096, 95% CI, 0.030–0.310; p < 0.001), and low ASA (OR 0.435, 95% CI, 0.249–0.761; p = 0.003) were associated with risk reduction for ER while malignancy (OR 5.302, 95% CI, 1.214–23.164; p = 0.027), open approach(OR 12.247, 95% CI, 5.227–28.694; p < 0.001), and intraoperative complications (OR 19.149, 95% CI, 7.091–51.710; p < 0.001) were associated with risk increase of ER.
ConclusionPostoperatively maintained hypotension and ileus were the most common causes of ER. Low body mass index, tumour size < 5 cm, and low ASA were risk reductions for ER, while malignancy, open approach, and intraoperative complications were the independent risk increase factors.
