Abstract

Background

Doege–Potter syndrome, characterized by solitary fibrous tumors and non-islet cell tumor hypoglycemia, is rare. Here, we report a case of Doege–Potter syndrome in which retroperitoneal tumor resection was performed with continuous intraoperative blood glucose monitoring.

Case presentation

A 37-year-old man presented with hypoglycemia-related symptoms, and a 10 × 12 × 9 cm tumor was found in his right kidney. Following tumor resection, insulin secretory abnormalities improved, and intraoperative blood glucose monitoring showed no hypoglycemic events. High levels of insulin-like growth factor-II confirmed the diagnosis of an insulin-like growth factor-II-producing tumor with non-islet cell tumor hypoglycemia. Postoperative serum insulin-like growth factor-II levels normalized, with no recurrence observed over 3 years.

Conclusions

This case highlights the rarity of primary retroperitoneal Doege–Potter syndrome, emphasizes the safety of intraoperative blood glucose levels during surgery, and suggests rapid recovery of insulin secretion postoperatively.

腹膜后 Doege-Potter 综合征术中血糖监测。

背景介绍Doege-Potter综合征以单发纤维性肿瘤和非胰岛细胞肿瘤低血糖为特征，非常罕见。在此，我们报告了一例在术中持续监测血糖的情况下进行腹膜后肿瘤切除术的 Doege-Potter 综合征病例：病例介绍：一名 37 岁男子出现低血糖相关症状，在其右肾发现一个 10 × 12 × 9 厘米的肿瘤。肿瘤切除后，胰岛素分泌异常有所改善，术中血糖监测显示未发生低血糖事件。高水平的胰岛素样生长因子-II确诊为胰岛素样生长因子-II分泌肿瘤，并伴有非胰岛细胞肿瘤性低血糖。术后血清胰岛素样生长因子-II水平恢复正常，3年来未发现复发：本病例凸显了原发性腹膜后多格-波特综合征的罕见性，强调了手术期间术中血糖水平的安全性，并提示术后胰岛素分泌可快速恢复。
