Objective:To analyze and summarize the clinical characteristics of autoimmune pancreatitis (AIP) patients in China from 2009 to 2018.Methods:Studies published from January 2009 to December 2018 were searched in CNKI, Wanfang and VIP databases by using " autoimmune pancreatitis" , " immune pancreatitis" and " IgG related pancreatitis" as search items, respectively. One hundred and ten articles were finally included, and a total of 2 364 AIP patients were involved. The gender, age, clinical manifestations, laboratory tests, radiological examination, treatment and prognosis of these AIP patients were analyzed and summarized.Results:Among the 2 364 AIP patients, there were 1 777 males and 587 females, with an average age of 58 years. The main clinical manifestations were jaundice(61.31%), abdominal pain(52.45%), abdominal discomfort(34.78%) and body weight loss(22.62%). 50.13% of the patients suffered from extrapancreatic manifestations. Serological examination detected significantly increased levels of IgG4 (74.14%), CRP (73.68%), IgG (71.41%), erythrocyte sedimentation (67.34%), total bilirubin (62.44%), ALT/AST(50.83%), CA19-9(43.85%) and positive rheumatoid factor (42.04%). Pancreatic diffuse (46.87%) and regional enlargement (21.87%) was found in AIP patients by imaging examination. The pancreatic pathological manifestations mainly included lymphoplasmic cell infiltration, pancreatic acinar destruction and atrophy, fibrous tissue proliferation, and positive IgG4 deposition by immunohistochemistry. 282 patients (11.92%) were misdiagnosed, while 70.12% of AIP patients were attenuated by hormones therapies.Conclusions:AIP, which is more common in male in China, is often accompanied by extrapancreatic manifestations. Although imaging examinations were helpful for diagnosis, the misdiagnosis rate remains high. Clinicians need to raise awareness, enhance the ability to diagnose and treat AIP, thus reducing misdiagnosis.

Objective:To compare the clinical efficacy between robot-assisted and free-hand percutaneous cannulated screwing (PCS) in the treatment of femoral neck fractures in the middle-aged and young patients.Methods:A retrospective study was conducted to analyze the clinical data of 53 patients with femoral neck fracture who had been treated with PCS from May 2020 to May 2022 at Department of Traumatic Surgery, Maoming Hospital Affiliated to Southern Medical University. In the robot group of 25 patients subjected to robot-assisted PCS, there were 11 males and 14 females with an age of (48.2 ± 11.9) years; in the free-hand group of 28 patients subjected to free-hand PCS, there were 13 males and 15 females with an age of (48.5 ± 9.8) years. The 2 groups were compared in terms of operation time, intraoperative bleeding, intraoperative guide drills, intraoperative fluoroscopy frequency, fracture union time, Harris hip score at the last follow-up and postoperative complications. Postoperative imaging examination was performed to evaluate distribution accuracy of the cannulated screws in the femoral neck (deviation between the screws and the femoral neck axis, parallelism between the screws and distance between the screws and the neck cortex).Results:There was no statistically significant difference between the robot and free-hand groups in the general clinical data before operation, showing comparability ( P>0.05). The robot group showed significantly shorter operation time [(32.7 ± 4.8) min], significantly less intraoperative bleeding [(14.6 ± 4.8) mL], significantly less intraoperative guide drillings [(3.5 ± 0.7) times] and significantly less intraoperative fluoroscopy frequency [(7.9 ± 1.4) times] than the free-hand group [(56.9 ± 11.3) min, (27.0 ± 7.3) mL, (9.1 ± 1.8) times and (16.3 ± 6.0) times)] (all P<0.05). Postoperative imaging showed that the deviation between the screws and the femoral neck axis was 4.4° ± 1.1° on the anteroposterior X-ray film and 3.2° ± 0.8° on the lateral X-ray film, the parallelism between the screws 4.9° ± 0.8° on the anteroposterior X-ray film and 3.0° ± 0.7° on the lateral X-ray film, and the distance between the screws and the femoral neck cortex (10.4 ± 2.7) mm in the robot group, all significantly smaller than those in the free-hand group [10.5° ± 2.8°, 4.9° ± 1.1°, 12.1° ± 4.0°, 5.1° ± 1.3°, and (15.4 ± 3.2) mm] (all P<0.05). All the 53 patients were followed up for (22.2 ± 8.5) months. All fractures got united. The fracture union time in the robot group [(20.6 ± 4.6) weeks] was insignificantly shorter than that in the free-hand group [(23.7 ± 7.7) weeks] ( P>0.05). At the last follow-up, the Harris hip score in the robot group [(88.6 ± 5.6) points] was significantly higher than that in the free-hand group [(84.8 ± 6.3) points] ( P<0.05). Follow-ups revealed 2 cases of internal fixation loosening, 1 case of screw head cutting and 1 case of femoral head necrosis in the free-hand group but none of such complications in the robot group. Conclusion:In the treatment of femoral neck fractures in the middle-aged and young patients, compared with free-hand PCS, robot-assisted PCS shows advantages of shorter intraoperative time, less bleeding, less fluoroscopic radiation, higher accuracy of screw placement, a lower incidence of postoperative complications and better functional recovery of the hip joint.
