Objective:To investigate the clinical imaging features and prognosis of von Hippel-Lindau (VHL) syndrome associated with pancreatic lesions.Method:The retrospective case-control study was conducted. The clinicopathological data of 161 patients with VHL syndrome who were admitted to Peking University First Hospital from September 2010 to August 2022 were collected. There were 83 males and 78 females, with age of onset as 27.0(range, 8.0-66.0)years. Observation indicators: (1) imaging results of VHL syndrome associated with pancreatic lesions; (2) clinical characteristics of VHL syndrome associated with pancreatic lesions; (3) comparison of clinicopathological factors in patients with VHL syndrome associated with pancreatic cystic lesions; (4) comparison of clinicopathological factors in patients with VHL syndrome associated with pancreatic neuroendocrine neoplasms (pNENs). (5) Treatment and prognosis of patients with VHL syndrome associated with pancreatic lesions. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Results:(1) Imaging results of VHL syndrome associated with pancreatic lesions. Of the 161 patients with VHL syndrome, there were 151 patients associated with pancreatic lesions and 10 patients not associated with pancreatic lesions. Of the 151 patients with VHL syndrome associated with pancreatic lesions, there were 136 patient with pancreatic cystic lesions and 34 patients with pNENs, 22 patients with both pNENs and pancreatic cystic lesions, and the type of pancreatic lesions could not be accurately determined in 3 cases. (2) Clinical characteristics of VHL syndrome associated with pancreatic lesions. The age of onset in 151 patients with VHL syndrome associated with pancreatic lesions was 33.0(range, 14.0-68.0)years. Cases with gene site mutation of exon 1, exon 2, exon 3 and other types of gene site was 51, 16, 43 and 41, respectively. There were 116 patients of VHL type 1 and 35 patients of VHL type 2. There were 92 patients with family history of VHL syndrome and 59 patients without family history of VHL syndrome. There were 127 patients combined with renal cell carcinoma, 112 patients combined with central nervous system lesions, 46 patients combined with retinal hemangioblastoma. Patients may combined with multiple lesions. (3) Comparison of clinicopathological factors in patients with VHL syndrome associated with pancreatic cystic lesions. The age of onset, VHL syndrome type (VHL1 type, VHL2 type) and cases combined with renal cell carcinoma were 32.5(range, 14.0-68.0)years, 110, 26 and 115 in 136 patients with VHL syndrome associated with pancreatic cystic lesions, versus 22.0(range, 8.0-64.0)years, 13, 12 and 14 in 25 patients with VHL syndrome not associated with pancreatic cystic lesions, showing significant differences in the above indicators between them ( Z=-3.384, χ2=9.770, 10.815, P<0.05). (4) Comparison of clinicopathological factors in patients with VHL syndrome associated with pNENs.

Objective:To explore whether prophylactic resection of orthotopic polycystic kidney before allogeneic kidney transplantation can reduce the incidence and severity of perioperative complications in patients with end-stage renal disease due to autosomal dominant polycystic kidney disease (ADPKD), and reduce the difficulty of surgery.Methods:A retrospective case-control study method was used to recruit a total of 27 patients who were diagnosed with ADPKD and underwent allogeneic kidney transplantation in Beijing Friendship Hospital, Capital Medical University from January 2013 to January 2021, they were divided into prophylactic resection group ( n=19) and non-prophylactic resection group ( n=8) according to whether orthotopic polycystic kidney disease was prophylactic resection before transplantation. Patients in prophylactic resection group underwent orthotopic polycystic kidney resection before transplantation, while patients in non-prophylactic resection group didn′t. The indexes such as hemoglobin, platelet, albumin, left ventricular wall thickness, left ventricular ejection fraction, difficulty of kidney transplantation, average postoperative hospital stay, pain, and complication rate before kidney transplantation were analyzed and compared between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for comparison between groups; Chi-square test was used for comparison of enumeration data between groups. Results:There was no significant difference in the general status of hemoglobin, platelets, albumin, left ventricular wall thickness, and left ventricular ejection fraction between the two groups before kidney transplantation ( P>0.05). However, the polycystic kidney volume [(2 409.8±1 899.8) cm 3] in the prophylactic resection group was greater than that in the non-prophylactic resection group [(1 340.2±290.6) cm 3], and the difference was statistically significant ( P=0.027). In terms of postoperative complications, 9 patients in the prophylactic resection group and 5 patients in the non-prophylactic resection group developed long-term low back pain or hematuria after transplantation, which were considered to be related to the unresected polycystic kidney disease, but the difference was not statistically significant ( P=0.678). Meanwhile, in both two groups, 3 patients underwent orthotopic polycystic nephrectomy after transplantation due to severe polycystic kidney complications. Although the incidence of complications in the prophylactic resection group (15.8%) was lower than that in the non-prophylactic resection group (37.5%), the difference was not statistically significant ( P=0.319). Conclusion:Prophylactic resection of orthotopic polycystic kidney before kidney transplantation can reduce the incidence and severity of polycystic kidney-related complications after transplantation, but has little effect on the operation time and intraoperative blood loss of kidney transplantation.
