Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Objective:To compare the efficacy of the horizontal plate plus raft screws above the acetabulum and fixation with screws only for acetabular fractures combined with dome impaction in the aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 20 aged patients with acetabular fractures combined with dome impaction, who were admitted to Tianjin hospital between May 2013 and January 2023, including 5 males and 15 females, aged 61-84 years [(72.2±7.3)years]. According to Letournel and Judet classification, 13 patients had anterior column fracture, 5 anterior column fracture combined with posterior transverse fracture and 2 two-column fracture. All the patients underwent open reduction and internal fixation through an anterior approach. Of them, 11 patients were treated with the fixation with the horizonal plate plus raft screws above the acetabulum (plate plus raft screw group) and 9 with the screws only (screw only group). The operative time, intraoperative blood loss, and intraoperative fluoroscopy times were compared between the two groups. The quality of fracture reduction was evaluated with the Matta′s radiographic criteria at 3 days after surgery and the function of the hip joint was assessed with Merle D′Aubigné and Postel scoring system at 3 months after surgery and at the last follow-up as well as the excellent and good rate at te last follow-up. The occurrence of postoperative complications was observed.Results:All the patients were followed up for 6-18 months [(13.1±3.1)months]. There were no significant differences in the operative time, intraoperative blood loss or intraoperative fluoroscopy times between the two groups ( P>0.05). According to the Matta′s radiographic criteria at 3 days after surgery, patients with anatomical reduction and satisfactory reduction accounted 6 and 5 in the plate plus raft screw group, compared to 5 and 4 respectively in the screw only group ( P>0.05). The values of Merle D′Aubigné and Postel score at 3 months after surgery and at the last follow-up were (14.0±2.4)points and (15.8±2.2)points in the plate plus raft screw group, which were higher than those in the screw only group [(11.0±2.6)points and (13.0±3.1)points] ( P<0.01). The values of Merle D′Aubigné and Postel score at the last follow-up of both groups were further enhanced from those at 3 months after surgery ( P<0.01). At the last follow-up, 3 patients were rated excellent, 6 good, 1 fair and 1 poor in the plate plus raft screw group, with an excellent and good rate of 81.8%, while in the screw only group, 3 were rated good, 2 fair and 4 poor, with an excellent and good rate of 33.3% ( P<0.05). One patient in the plate plus raft screw group and 5 in the screw only group had displacement of the dome impaction fragment combined with traumatic arthritis after surgery ( P<0.05). Conclusion:For acetabular fractures combined with dome impaction in the aged patients, the horizontal plate plus raft screw above the acetabulum can effectively improve the function restoration of the hip joint and reduce the occurrence of the displacement of the dome impaction fragment and traumatic arthritis after surgery compared to the fixation with screws only.

Objective:To explore the effectiveness and safety of robot-aided percutaneous anterior column screw combined with posterior plate fixtation treatment for transverse acetabular fractures with posterior wall.Methods:A retrospective analysis was conducted on the data of 13 patients with transverse acetabular fractures and posterior wall fractures treated by robot-aided percutaneous anterior column screws combined with posterior plate in Tianjin Hospital from May 2016 to May 2021. There were 9 males and 4 females, aged 49.1±8.5 years (range, 25-65 years), 9 cases of vehicle accidents, 2 cases of falling injuries, 2 cases of impact injuries, 7 cases of combined posterior hip dislocations, and 1 case of sciatic nerve injury. Apply Kocher-Langenbeck approach for reduction and fixation of the posterior wall and the posterior column and indirect reduction of the anterior column. Use robot navigation for percutaneous anterior column screw fixation, and record the time of inserting anterior column screws, incision length, and complications. The quality of fracture reduction was evaluated using Matta imaging, and the degree of ectopic ossification was evaluated using Brooker classification. The Matta modified Postel Merle D'Aobigne score was used to evaluate the function at 3, 6 months after surgery and at the last follow-up.Results:All 13 patients successfully completed the surgery. The insertion time of the anterior column screw was 19.4±4.0 min (range, 17-23 min), and the incision length was 8.0±1.4 mm (range, 6-10 mm). Postoperative imaging examination showed that all anterior column screws were located within the bone canal, with a screw length of 108.3±11.2 mm (range, 90-130 mm), and no complications such as nerve or vascular injury or incision infection occurred. All 13 patients were followed up for a period of 12-36 months, with an average of 18.6 months; All fractures healed, with a healing time of 2-6 months, average 3.4 months. According to the Matta imaging evaluation method, 11 of 13 patients had anatomical reduction of fractures, and 2 were evaluated as incomplete reduction due to a 1-2 mm gap in the anterior column. The anatomical reduction rate was 84%. At postoperative 3, 6 months and the last follow-up, the modified Postel Merle D'Aobigne scores were 13.4±1.1, 15.8±1.5, and 17.0±1.7, respectively, with statistically significant differences ( F=7.78, P=0.007). The difference between the last follow-up and postoperative 3 months was statistically significant ( P=0.002), and there was no statistically significant difference compared to postoperative 6 months ( P=0.222). At the last follow-up, 8 cases were excellent, 4 cases were good, and 1 case was fair, with an excellent and good rate of 92%. There was no occurrence of ectopic ossification, traumatic arthritis, or necrosis of the femoral head. Conclusion:Robot-aided percutaneous anterior column screw combined with posterior plate treatment for transverse acetabular fractures with posterior wall is safe and effective, and is worthy of clinical promotion.

Objective:To evaluate the clinical outcome of Robot-assisted sacroiliac screw fixation in the treatment of fragility fracture of the sacrum in the elderly.Methods:From March 2016 to June 2022, a retrospective analysis was performed on 30 patients with fragility fractures of the sacrum in the elderly who accepted robot-assisted sacroiliac screw to treat fragility fractures of the sacrum in our hospital. There were 12 males and 18 females with average age 71.03±8.25 years (range, 60-89 years). According to the classification of fragility fractures of the pelvis (FFP) in the elderly, there were 22 patients with FFP II, 2 patients with FFP III, and 6 patients with FFP IV. Surgical planning was based on the average CT value of S 1 channel and whether there is a transsacral screw channel. Robot-assisted sacroiliac screw fixation was performed during surgery. The pain of pre-operation and post-operation was evaluated using the visual analogue scale (VAS), the position of sacroiliac screws was evaluated by Gras grading, and the degree of functional recovery after surgery was evaluated using the Majeed function score. Results:All 30 patients successfully completed the operation. The mean operation time was 27.00±6.68 min (range, 18-35 min), the mean fluoroscopy times were 27.13±5.16 (range, 18-34), and the mean blood loss was 30.53±6.61 ml (range, 23-38 ml). All patients were followed up, and the mean follow-up time was 19.03±7.8 months (range, 8-25 months). The VAS was 5(5, 6), 4(3, 4), 3(2, 3), 0(0, 1) points before surgery, 1 week, 2 months and 6 months after surgery, respectively, and the difference was statistically significant ( H=103.26, P<0.001). After the surgery of 2 months, 6 months and the last follow-up time, the Majeed function scores were 88(83, 90), 91(87, 92), 92(90, 93) points, respectively, and the difference was statistically significant ( H=19.59, P<0.001). Screw position was evaluated according to Gras grading at 3 days after surgery, including 28 cases of level I, 2 cases of level II, and no screw penetrated the cortical bone or entered the sacral canal or sacral foramen. No vascular or nerve injury occured during the operation. 28 patients with FFS met the fracture healing criteria, and the healing time was 4.54±1.57 months (range, 3-7 months). Two patients had bone nonunion, one of whom underwent anterior ring plate removal due to infection of the pelvic anterior wound, and one month later, pelvic CT scan revealed loosening of the sacroiliac screw; the other one is considered to be related to too early weight bearing. Conclusion:For fragility fractures of the sacrum in elderly, Robot-assisted sacroiliac screw is an effective minimally invasive treatment, with high accuracy of screw placement, effective pain reduction, improved fracture healing rate, and achieve the satisfactory clinical efficacy.

Objective To evaluate the effect of different techniques of hepatic artery reconstruction on postoperative hepatic artery complications and clinical prognosis in liver transplantation. Methods Clinical data of 140 liver transplant recipients were retrospectively analyzed. All recipients were divided into the conventional hepatic artery reconstruction group (n=123) and special hepatic artery reconstruction group (n=17) according to hepatic artery reconstruction methods. Intraoperative and postoperative clinical indexes, the incidence of postoperative hepatic artery complications and survival rate were compared between two groups. Results The alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels at postoperative 1 d, total bilirubin (TB) at postoperative 7 d and prothrombin time international normalized ratio (PT-INR) at postoperative 30 d in special hepatic artery reconstruction group were higher than those in conventional hepatic artery reconstruction group, and the differences were statistically significant (all P < 0.05). There were no significant differences in the operation time, anhepatic phase, intraoperative blood loss, intraoperative transfusion volume of red blood cells, cold or warm ischemia time, the length of intensive care unit (ICU) stay, the length of hospital stay and postoperative blood flow of liver allograft between two groups (all P > 0.05). In the conventional hepatic artery reconstruction group, 5 recipients developed hepatic artery complications, whereas no hepatic artery complications occurred in the special hepatic artery reconstruction group, with no significant difference between two groups (P > 0.05). In the special hepatic artery reconstruction group, the 1-, 3- and 5-year cumulative survival rates were equally 82.4%, compared with 85.0%, 78.9% and 75.6% in the conventional hepatic artery reconstruction group, respectively. There was no significant difference between two groups (all P > 0.05). Conclusions When hepatic artery variations and (or) lesions are detected in donors and recipients, use of special hepatic artery reconstruction may effectively restore the hepatic arterial blood flow of liver allograft after liver transplantation, and will not affect the incidence of hepatic artery complications and survival rate of the recipients following liver transplantation.

Objective:To compare the population characteristics, the positive rate of screening, the detection rate of breast cancer, early diagnosis rate and the cost between the mass screening group and opportunistic screening group of breast cancer.Methods:This study is a prospective multicenter cohort study conducted from January 1, 2014 to December 31, 2016. The participants were enrolled for mass screening or opportunistic screening of breast cancer. After completing the questionnaire, all the participants received breast physical examination and breast ultrasound examination every year for 3 rounds by year. The participants′ characteristics and screening results of the two groups were compared by χ 2 test, Fisher exact test or Wilcoxon rank-sum test. Results:A total of 20 080 subjects were enrolled. In the mass screening group, 9 434 (100%), 8 111 (85.98%) and 3 940 (41.76%) cases completed the 3 rounds of screening, and 10 646 (100%), 6 209 (58.32%) and 2 988 (28.07%) cases in the opportunistic screening group, respectively. In the opportunistic screening group, the proportions of less than 3 months lactation (1 275/9 796 vs. 1 061/8 860, χ2=4.597, P=0.032), non-fertility (850/10 646 vs. 574/9 434, χ2=27.400, P<0.01), abortion history (6 384/10 646 vs. 5 062/9 434, χ2=81.232, P<0.01), postmenopausal (2 776/10 646 vs. 2 217/9 434, χ2=17.757, P<0.01), long-term oral contraceptives(>6 months) (171/10 646 vs. 77/9 434, χ2=25.593, P<0.01) and family history of breast cancer in first-degree relatives (464/10 646 vs. 236/9 434, χ2=51.257, P<0.01) were significantly higher than those in mass screening group. The positive rate of screening (514/10 646 vs. 128/9 434, χ2=194.736, P<0.01), the detection rate of breast cancer (158/10 646 vs. 13/9 434, χ2=107.374, P<0.01), and positive rate of biopsy (158/452 vs. 13/87, χ2=13.491, P<0.01) in the opportunistic screening group were significantly higher than those of the mass screening group. The early diagnosis rate of the mass screening group was significantly higher than the opportunistic screening group (10/12 vs. 66/141, χ2=5.902, P=0.015). The average cost for detecting each breast cancer case of the mass screening group was 215 038 CNY, which was 13.6 times of the opportunistic screening group (15 799 CNY/case). In the opportunistic screening group, the positive rate of biopsy in primary hospitals was significantly lower than that in large-volume hospitals (79/267 vs. 79/185, χ2=8.267, P=0.004), but there was no significant difference in the mass screening group (6/37 vs. 7/50, χ2=0.082, P=0.774). Conclusions:Breast cancer screening can improve early detection rate. Compared with the mass screening mode, the opportunistic screening mode has the advantages of higher proportion of high-risk factors, higher positive rate of screening, higher detection rate of breast cancer, higher positive rate of biopsy, and lower cost of screening. However, the early diagnosis rate of breast cancer of opportunistic screening is lower than that of mass screening. The positive rate of opportunistic screening in primary hospitals is lower than that of large-volume hospitals. The two screening modes have their own advantages and should be chosen according to local conditions of different regions in China.

Conclusions:Breast cancer screening can improve early detection rate. Compared with the mass screening mode, the opportunistic screening mode has the advantages of higher proportion of high-risk factors, higher positive rate of screening, higher detection rate of breast cancer, higher positive rate of biopsy, and lower cost of screening. However, the early diagnosis rate of breast cancer of opportunistic screening is lower than that of mass screening. The positive rate of opportunistic screening in primary hospitals is lower than that of large-volume hospitals. The two screening modes have their own advantages and should be chosen according to local conditions of different regions in China.

Objective: To summarize the status of immediate breast reconstruction (IBR) after mastectomy in Beijing City, Tianjin City and Hebei Province. Methods: A retrospective analysis was made on the data of 382 cases with breast cancer who were treated and followed up successfully with immediate breast reconstruction after mastectomy from January 2012 to December 2016 in Beijing City, Tianjin City and Hebei Province. Clinic data of the followed-up 382 cases (all female, age (38.5±4.2) years (range: 24 to 70 years)), including general information, tumor information, sugery methods, and treatments after surgery were collected. The survival status, metastasis,complications and prognosis were followed up. Cosmetic effcet was evalated by Harris method, and life quality by Functional Assessment of Cancer Therapy-Breast scale (FACT-B). χ² test was used to compare the difference between year 2012 and year 2013 to 2016. Bonferroni method was used to correct the inspection level, which was 0.05/10=0.005. The trend of IBR rate (ratio of IBR to modified radical mastectomy) from 2013 to 2016 was analyzed by trend χ² test. Results: There was 46 cases in stage 0, 152 cases in stage Ⅰ, 165 cases in stage Ⅱ, 19 cases in stage Ⅲ. Twenty-five cases was treated by neoadjuvant chemotherapy, 231 by chemotherapy and 35 by radiotherapy. The proportion of implant reconstruction was 48.7% (186/382), more than expanded of 21.5% (82/382), with latissimus dorsi of 12.0% (46/382), TRAM of 8.9% (34/382), DIEP of 2.1% (8/382), and latissimus plus implant of 6.8% (26/382). According to the Harris standard, the excellent and good rate of the cosmetic effect of the reconstructed breast was 93.7%. The score of FACT-B was 108.20±16.9 (range: 67 to 144) 1 year postoperatively. Compared with 2012, the IBR rate was significant increased, till 2015, the IBR rate was 153/10 000 cases (χ²=47.028, P=0.000). Conclusions There is a significant increase on IBR rate in Beijing City, Tianjin City and Hebei province by year. Most of cases received IBR is stage Ⅰ to Ⅱ. Implant reconstruction is the main reconstructive method. Postoperative cosmetic effects and quality of life are both meet patients′ demon.

Objective:To explore multidisciplinary team (MDT) for the treatment of hip fracture in the elderly.Methods:A retrospective analysis was done of the 196 elderly patients who had been admitted to Department of Joint Surgery, Beijing Shijitan Hospital from September 2017 to December 2018 for hip fractures. They were divided into 2 groups depending on whether MDT had been applied or not. In the MDT group of 102 patients, there were 43 males and 59 females with an age of 81.9±8.4 years, and 63 femoral neck fractures and 39 intertrochanteric fractures. In the traditional treatment group of 94 patients, there were 37 males and 57 females with an age of 81.3±8.6 years, and 55 femoral neck fractures and 39 intertrochanteric fractures. The 2 groups were compared in terms of complications and mortality during hospitalization, interval from admission to surgery, total hospital stay, and Harris hip scores at 6 months after surgery.Results:There were no statistically significant differences in general data before surgery between the 2 groups, indicating comparability ( P>0.05). Eighty-four patients (89.4%) in the traditional treatment group and 98 patients (96.1%) in the MDT group underwent surgery, showing no significant difference between the groups ( χ2=3.327, P=0.068). In the patients undergoing surgery in the MDT group, the incidences of postoperative delirium [12.2% (12/98)], pulmonary infection [11.2% (11/98)], cardiogenic disease [13.3%(13/98)], electrolyte disturbance[12.2%(12/98)] and deep venous thrombosis of lower extremity [6.1% (6/98)] were significantly lower, the interval from admission to surgery (1.9 d±0.9 d) and total hospital stay (10.2 d±0.9 d) significantly shorter, and Harris hip scores (81.3±6.2) at 6 months after surgery significantly higher than those in the patients undergoing surgery in the traditional treatment group [31.0%(26/84), 22.6% (19/84), 25.0% (21/84), 28.6% (24/84), 16.7%(14/84); 3.1 d±1.6 d and 14.1 d±6.2 d; 75.4±7.8; respectively] (all P<0.05). Conclusion:In the treatment of hip fracture in the elderly, multidisciplinary team is effective in reducing complications during hospitalization, shortening the interval from admission to surgery and total hospital stay, and promoting functional recovery of the hip.

Objective: To explore the treatment outcome of triangular osteosynthesis (TOS) for the treatment of unilateral Isler type II lumbosacral junction injuries (LSJIs). Methods: Data of sixteen patients with unilateral Isler type II LSJIs surgically who were treated in our Hospital from March 2015 to February 2017 were retrospectively analyzed. There were 13 males and 3 females with an average age of 35.5 years (range, 24-61 years). Seven patients were multiple injuries including head, thoracic, musculoskeletal and nerve injuries. According to Isler classification of LSJIs, there were 5 cases of type IIa, 9 of type IIb and 2 of type IIc. All the LSJIs combined with ipsilateral sacral fractures. The sacral fractures were classified by Denis classification with 1 case of zone I, 13 cases of zone II and 2 cases of zone III. According to Tile classification of pelvic fractures, there were 3 cases of type B2, 11 of type C1 and 2 of type C3. There were 3 cases combined with sacral nerve injury among which there were 2 cases of grade II and 1 case of grade III according to Gibbons classification of neurologic deficits. All cases were surgically treated with triangular osteosynthesis. There were 14 cases combined with iliosacral screws fixation in S₁ and 2 cases combined with posterior locking plates. Results: All patients were followed up for 20.6 months (range, 16-30 months). CT scan was conducted 12 to 24 months after surgery which showed all the sacral fractures were union, and 2 cases achieved bony fusion in L₅S₁ facets while the other 14 didn’t. According to Majeed’s pelvic injury evaluation, clinical outcomes were rated with excellent in 12 cases, good in 2 cases, fair in 2 cases. The excellent and good rate was 87.5% (14/16) . According to Mears-Velyvis evaluation criterion, there were 14 cases with anatomical reduction and 2 cases with satisfactory reduction. Among the 3 cases with sacral nerve injury, 2 cases were improved from Gibbons grade II to grade I and the other 1 case was improved from Gibbons grade III to grade II, still feeling numbness on the lateral foot. There were no intraoperative complications in all patients such as neurovascular injuries. No incision infection, fat liquefaction and other incision related complications occurred postoperatively. Irritation and pain in iliac spine about prominent implant occurred in 1 case and lumboscaral stiffness in 1 case, in which the symptom relieved and disappeared after implants removal. Conclusion Triangular osteosynthesis can provide enough stabilization for Isler type II LSJIs and achieve satisfactory outcomes.
