Objective:To analyze the clinical characteristics of acute pancreatitis.Methods:The retrospective case-control study was conducted. The clinical data of 558 patients with acute pancreatitis who were admitted to The First Affiliated Hospital of Xi′an Jiaotong University from June 2015 to June 2023 were collected. There were 352 males and 206 females, aged (46±15)years. Observation indicators: (1) general situations of acute pancreatitis patients; (2) etiology of acute pancreatitis patients; (3) severity of acute pancreatitis patients; (4) chronic diseases in acute pan-creatitis patients; (5) complications in acute pancreatitis patients; (6) subgroup analysis of patients with recurrent acute pancreatitis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Bonferroni correction was used for pairwise comparison. Results:(1) General situations of acute pancreatitis patients. There were significant differences in gender, age, total duration of hospital stay, smoking, and alcohol consumption between the first episode of acute pancreatitis patients and the recurrent acute pancreatitis patients ( P<0.05). (2) Etiology of acute pancreatitis patients. There were significant differences in gallstones and hyperlipidemia between the first episode of acute pancreatitis patients and the recurrent acute pancreatitis patients ( P<0.05). (3) Severity of acute pancreatitis patients. Of the 443 patients with first episode of acute pancreatitis and 115 patients with recurrent acute pancreatitis, cases with mild acute pancreatitis, cases with moderate-severe acute pancreatitis, cases with severe acute pan-creatitis were 320 and 83, 24 and 9, 99 and 23, showing no significant difference between them ( P>0.05). (4) Chronic diseases in acute pancreatitis patients. There were significant differences in com-plication as hyperlipidemia, fatty liver and diabetes between the first episode of acute pancreatitis patients and the recurrent acute pancreatitis patients ( P<0.05). (5) Complications in acute pancrea-titis patients. There was no significant difference in terms of acute necrotic collection, acute peripan-creatic fluid accumulation, walled-off necrosis, pancreatic pseudocyst, infectious pancreatic necrosis, systemic inflammatory response syndrome, respiratory system complications, circulatory system complications, renal complications, sepsis, abdominal compartment syndrome, or pancreatic ence-phalopathy between the first episode of acute pancreatitis patients and the recurrent acute pancrea-titis patients ( P>0.05). (6) Subgroup analysis of patients with recurrent acute pancreatitis. ① Combination with chronic diseases. Of the 115 patients with recurrent acute pancreatitis, cases with mild acute pancreatitis, cases with moderate-severe acute pancreatitis, cases with severe acute pancreatitis were 83, 9, 23, and there were 25, 8, 11 cases of them with hyperlipidemia, respectively, showing a significant difference among them ( P<0.05). ② Complications. Of the 115 patients with recurrent acute pancreatitis, there were 44 cases with hyperlipidemia and 71 cases without hyper-lipidemia, and there were significant differences in acute peripancreatic fluid accumulation and renal complications between them ( P<0.05). Conclusions:Recurrent acute pancreatitis is more common in males. Compared with first episode of acute pancreatitis, cases with recurrent acute pancreatitis usually have younger age, shorter total duration of hospital stay, higher proportion of smoking and drinking. The etiology of recurrent acute pancreatitis is composed of lower levels of biliary diseases and higher levels of hyperlipidemia. Patients with recurrent acute pancreatitis have higher proportion of comorbidities as hyperlipidemia, fatty liver and diabetes. There was no signifi-cant difference in the incidence of complications between first episode of acute pancreatitis and recurrent acute pancreatitis. Compared with recurrent acute pancreatitis patients without concomi-tant hyperlipidemia, recurrent acute pancreatitis patients with concomitant hyperlipidemia are more prone to acute peripancreatic fluid accumulation and renal complications.

Objective:To evaluate the emergency iliosacral screw fixation assisted by TiRobot for unstable posterior pelvic ring fracture.Methods:The 26 patients with unstable pelvic fracture were analyzed retrospectively who had undergone emergency iliosacral screw fixation at Department of Orthopedics & Traumatology, Beijing Jishuitan Hospital from June 2018 to December 2020. They were divided into 2 groups depending on whether orthopaedic TiRobot was used to assist screw insertion. In the observation group of 14 cases subjected to TiRobot-assisted insertion of iliosacral screws, there were 10 males and 4 females with an age of (45.9 ± 10.1) years; in the control group of 12 cases subjected to conventional manual insertion of iliosacral screws, there were 9 males and 3 females with an age of (49.2 ± 11.3) years. All the surgeries were conducted within 24 hours after injury. The 2 groups were compared in terms of screw insertion time, pin insertion, intraoperative blood loss, fluoroscopy time, postoperative screw position, fracture reduction and Harris hip score at the final follow-up.Results:The 2 groups were comparable because there was no significant difference between them in their preoperative general clinical data or follow-up time ( P>0.05). The screw insertion time [(16.1 ± 3.4) min] and fluoroscopy time [(8.1 ± 3.3) s] in the observation group were significantly shorter than those in the control group [(26.4 ± 5.4) min and (25.2 ± 7.4) s], and the pin insertions [1 (1, 2) times] and intraoperative blood loss [(10.5 ± 6.4) mL] in the former were significantly less than those in the latter [6 (3, 8) times and (24.8 ± 6.7) mL] (all P<0.05). Postoperatively, the sacroiliac screw position was excellent in 18 cases and good in 2 in the observation group while excellent in 14 cases, good in 2 and poor in 2 in the control group; the fracture reduction was excellent in 12 cases, good in one and fair in one in the observation group while excellent in 10 cases, good in one and fair in one in the control group, showing insignificant differences in the above comparisons ( P>0.05). There was no significant difference either in the Harris hip score at the final follow-up between the 2 groups ( P>0.05). Conclusion:Compared with conventional manual insertion of iliosacral screws, emergency iliosacral screw fixation assisted by TiRobot can effectively decrease surgical time and reduce operative invasion due to a higher accuracy rate of screw insertion.

Objective:To identify the risk factors for massive blood loss in pediatric patients with congenital scoliosis undergoing posterior hemivertebra resection.Methods:The clinical data of pediatric patients with congenital scoliosis who underwent posterior hemivertebra resection in our hospital from May 2017 to July 2019 were collected.The children were divided into group A (massive blood loss, blood loss/blood volume ≥30%) and group B (non-massive blood loss, blood loss/blood volume <30%) according to intraoperative blood loss.Logistic regression analysis was used to stratify the risk factors.Results:A total of 108 pediatric patients were enrolled in the study including 29 cases in group A and 79 cases in group B, respectively.There were significant differences in the preoperative Cobb angle, body mass index, the number of fused levels, the number of screws and operative time between the two groups ( P<0.05). Logistic regression analysis showed that the preoperative Cobb angle, operative time, the number of fused levels and body mass index were the risk factors for intraoperative massive blood loss ( P<0.05). Conclusion:Lower BMI, larger Cobb angle, increased operative time and more fused levels are the risk factors for massive blood loss in pediatric patients with congenital scoliosis undergoing posterior hemivertebra resection.

Objective To compare the clinical outcome of internal fixation(IF)and total hip arthroplasty (THA)for the elderly patients with displaced femoral neck fracture. Methods A total of 128 patients with dis-placed femoral neck fracture admitted from January 2010 to December 2012 were selected and divided into IF group(61 cases)and THA group(67 cases). The operation and hospitalization index were compared between the 2 groups. All patients underwent follow-ups after operation. The functional recovery scale for hip fracture (FRS) and EQ-5D index were applied to evaluate the clinical outcomes periodically. Results Compared to THA group, the intraoperative trauma ,operation time and bed days were less in IF group(P0.05). Follow-ups at all time points revealed hip function in THE group is better than that in IF group(P 0.05). Within 3 years,the costs related to fracture were 41772 yuan for IF group and 61174 yuan for THA group respectively. Conclusion Both internal fixation and total hip arthroplasty can provide satisfactory outcome for elderly patients with displaced femoral neck fracture. Compared with IF ,THA causes bigger trauma and costs more ,but ends up with lower complication incidences ,and improve hip function in a shorter period.
