ABSTRACT
Objective@#To analyze the causes of preoperative miscarriage of pancreatic serous cystadenoma (SCN) and find the ways to improve it.@*Methods@#Clinical data of 425 pancreatic cystic neoplasm patients who underwent surgical resection from January 2006 to December 2016 in Department of Pancreatic Surgery in Huashan Hospital were retrospectively analyzed.Excel database was created which covered 128 fields of 7 fields: general information of patients, preoperative blood biochemical indexes, tumor markers, surgical related data, postoperative complications, imaging findings and pathology.One hundred and sixty-one cases of SCN were analyzed in depth, mainly in three aspects: surgical benefit, preoperative imaging diagnostic value and interference factors in preoperative judgement.The classification data were analyzed by χ2 test and the quantitative data were analyzed by t test.The Logistic regression model was used for multiple factor analysis.@*Results@#Of the 425 PCN cases surgically removed, 161 cases (37.9%) were SCN, the incidence of operative complications was 40.4%(65/161), the hospitalization days was (20.7±12.1)days and the medical cost was (75 267±37 866) yuan.Only 3 of 161 cases of SCN were accurately diagnosed by preoperative imaging methods, 61 cases were diagnosed as "cystic lesions of pancreas" (37.9%) and 52 cases were diagnosed as "pancreatic cystadenoma" (32.3%). SCN was misdiagnosed as MCN(32.3%) and IPMN(28%) before operation.25.5% of them were diagnosed as SCN before operation, but still underwent radical operation.The rate of preoperative imaging diagnosis for identifying SCN was 62.8%.The lack of preoperative endoscopy and the lack of understanding of the image characteristics and biological behavior of SCN were the most important factors affecting the accuracy of preoperative judgment.Statistics found that gender, age, CA125 and tumor location can be used as independent factors contribute to the clinical identification(χ2=8.995, P=0.003; χ2=10.019, P=0.007; t=3.157, P=0.002; χ2=6.790, P=0.009). Logistic analysis showed that women, older than 60 years old, the tumors located in the pancreatic body and tail were the independent factors of SCN classification and diagnosis (OR=0.481, 0.376, 0.577, 0.666, 95% CI: 0.305-0.759, 0.199-0.710, 0.361-0.924, 0.433-1.024, P=0.002, 0.003, 0.022, 0.064).@*Conclusions@#SCN has more benign biological behavior.Although surgical excision is acceptable for clinical safety, the corresponding benefit is very limited.It is possible to improve the rationality of SCN clinical operation decisions to some extent by performing endoscopic examination, imaging doctors to improve the SCN feature recognition and surgeons to enhance the awareness of SCN.
ABSTRACT
Objective To investigate the prognostic outcome of open reduction and internal fixation(ORIF)with radial head resection in treatment of comminuted radial head fractures so as to discuss the corresponding operation options.Methods A series of 23 patients with Mason type Ⅲ or Ⅳ radial head fractures were enrolled in the study including 11 males and 12 females.Eight patients(three with Mason type Ⅲ and five with Mason type Ⅳ)underwent radial head resection and 15(seven with Mason type Ⅲ and eight with Mason type Ⅳ)received open reduction and internal fixation including nail and plate fixation in eight and screw and K-wire fixation in seven.The outcomes were assessed in regard of range of motion,radiographic findings,visual analogous scale(VAS)of pain,patient satisfaction degree,disabilities of the arm,shoulder and hand score system(DASH)and the Broberg & Morrey elbow performance score system.Results The follow-up period ranged from 12 to 65 months(mean 35 months),which showed fracture healing in all patients,with no traumatic arthritis happened.The mean range of flexion and extension arc at the elbow of ORIF group and resection group was 132°and 79.4°(P＜0.01)and the patient satisfaction was 9.1 and 8.0(P ＜0.05)respectively.According to the Broberg & Money elbow performance score system,the score was average 93.9 in the ORIF group,with excellent result in nine patients,good in five and fair in one,while the score was average 80.6 in the resection group,with excellent result in two patients,good in two and fair in four.There was statistical difference between two groups(P ＜0.01).The DASH score of the ORIF and resection group was 2.9 and 18.1 respectively(P＜0.05).Conclusions ORIF has better elbow motion,elbow function,daily living and satisfactory outcomes than radial head resection and is recommended for treatment of Mason type Ⅲ or Ⅳ radial head fractures for repair of the radial head as far as possible.
