Abstract Objective: The patellar inferior pole fracture is typically comminuted. Hence, achieving firm fixation and early activity is highly challenging. In this article, we employed the method of wire cerclage through a generated bone hole to reduce the fracture. Our objective was to compare the clinical efficacy of patellar concentrator alone with a combination of cerclage and patellar concentrator in the treatment of patellar inferior pole fracture.Methods: We conducted a retrospective review of patients with patellar inferior pole fractures, who underwent patellar concentrator fixation only (the control group) or cerclage combined with patellar concentrator fixation (the experimental group), performed by a single surgeon, between July 2015 and October 2019. Our analysis included surgical indexes like7 aspects (fracture gap after operation, operation time, intra-operative blood loss,intra-operative number of C-arm fluoroscopies conducted, Insall-Salvati ratio calculated immediately after operation, initial range of motion on the 7th day after operation, and fracture healing time), as well as the Bostman score and complications recorded on 1-, 3-, 6-, and 12-month follow up post operation.Results:A total of 94 patients with patellar inferior pole fracture and a minimum 1-year followup were recruited. Following operation, the control group had 33(71.74%) patients with a fracture gap of 0-2 mm and 13(28.26%)patients with a fracture gapgreater than 2 mm(P=0.002). Conversely,the experimental grouphad46(95.83%)patients with a fracture gap of 0-2 mm and 2(4.17%) patients with a fracture gapgreater than 2 mm(P=0.002). Compared to the control group, the experimental group did not experience enhanced operation time or intra-operative blood loss (P=0.811, P=0.823). The Insall-Salvati ratio and initial range of motion in the experimental group were larger than the control group (P=0.037, P=0.000). Alternately, the number of intra-operative C-arm fluoroscopies conductedand fracture healing time of the experimental group were considerably less than the control group (P=0.003,P=0.000).Moreover, at 1-, 3-, 6-, and 12-month follow ups after operation, the Bostman scores of the experimental group were remarkably higher than the control group (P< 0.05).At 12 months post operation, 23 cases (50%) were classified as excellent, 22 cases (47.83%) were good, and 1 case (2.17%) was poor in the control group(P=0.005). In the meantime, in the experimental group, 38 cases (79.17%) were deemed as excellent and 10 cases (20.83%) were good (P=0.005).Lastly, complications were detected in 3 cases (6.52%;1 case of internal fixation loss,2 cases of hematoma) within the control group, and in 1 case(2.08%; marginal wound necrosis) within the experimental group. There was no wound infection, implant discomfort, or broken fixation in eithergroup.Conclusion: Managingthe patellar inferior pole fracture with wire cerclage through a generated bone hole is both simple and effective. Moreover, an additional step of patellar concentrator fixation facilitates early functional exercise, with satisfactory clinical outcome.

Objective: To explore the clinical efficacy of plastic surgery of asymmetric double eyelid. Methods: The clinical data of 70 patients with asymmetrical double eyelid who underwent plastic surgery in our hospital from April 2018 to December 2019 were retrospectively analyzed. The patients were divided into different groups based on different plastic surgery procedures. The control group (n=35 cases) were the patients who underwent double eyelid incision method, and the patients who used embedding double eyelid method were included in the observation group (n=35 cases). The operation time, intraoperative blood loss, incision size, healing time of incision, satisfaction of plastic surgery and occurrence of complications were compared between the two groups. Results: The operation time and incision healing time of the observation group were shorter than those of the control group. The intraoperative blood loss and incision were less than those of the control group, and the satisfaction was higher than that of the control group. The difference was statistically significant (P<0.05). The incidence of complications in the observation group was slightly lower than the control group, but the difference was not statistically significant (P>0.05). Conclusion: For asymmetric double eyelid, it should undergo embedding double eyelid plastic surgery, because the operation time and incision healing time are shorter. And intraoperative blood loss and incision size are smaller, which can improve patient satisfaction and reduce the incidence of complications.

Objective: To study the clinical effect of modified circumcision in the treatment of phimosis and excessive foreskin. Methods: 110 patients with overly long foreskin or phimosis were divided into experimental group and control group by random number table method, with 55 cases in each group. The experimental group was treated with modified circumcision, and the control group was treated with traditional manual cutting and suture. Then the clinical effects of the two treatments were compared. Results: Two different surgical procedures were performed. During the operation, the blood loss of the experimental group was less than that of the control group; the operation time and wound healing time were shorter than those of the control group; after the operation, the incidence of related complications in the experimental group was 14.55%, which was significantly lower than For 25.45% of the control group, the clinical treatment effect was obvious, and the difference was statistically significant (P<0.05). Conclusion: The clinical effect of modified circumcision in the treatment of patients with phimosis and excessive foreskin is good. Compared with the traditional manual cutting and suture treatment, it not only has the advantages of simple operation and clinical application, but also benefits the rehabilitation of patients. Rehabilitation time reduces the incidence of postoperative complications. It is an ideal treatment plan for this type of disease in the current clinic, and it is worthy of popularization and application in general surgery and reproductive surgery.

Objective To compare the clinical effects between anatomical locking plates and interlocking intramedullary nails in patients with Danis-Weber B lateral malleolus fractures. Methods This retrospective study enrolled patients with Danis-Weber B fractures of the lateral malleolus. All the operations were completed by the same group of surgeons. The reduction effect, operation time, intraoperative blood loss, hospital stay, fracture healing time and ankle functional outcomes (Olerud-Molander Ankle Score [OMAS]) were compared. Postoperative complications, including incision infections, fixation discomfort and internal fixation loosening, were also compared. Results This study enrolled 73 patients that were treated with either an anatomical locking plate (locking plate group; n = 37) or an interlocking intramedullary nail (intramedullary nail group; n = 36). There was no significant difference between the two groups in terms of reduction effect, hospital stay and OMAS. The intramedullary nail group had significantly lower operation time, intraoperative blood loss and fracture healing time compared with the locking plate group. Postoperative complications in the intramedullary nail group were significantly lower compared with the locking plate group. Conclusion Using intramedullary nails resulted in more satisfactory functional outcomes compared with using locking plates in patients with Danis-Weber B fractures of the lateral malleolus.

AIM: to assess results of 3D laparoscopic ventral mesh rectopexy versus traditional 2D laparoscopy for rectocele and rectal prolapse.PATIENTS AND METHODS: a prospective randomized study (NCT 04817150) included patients aged 18 to 70 years who underwent laparoscopic ventral mesh rectopexy for rectocele and/or rectal prolapse. The assessment included operation time, intraoperative blood loss, complications rate and their severity by Clavien-Dindo scale, the pain intensity by VAS, the volume of the fluid collection in the implant site 2–3 days and 2–3 weeks after the procedure. The surgeon’s comfort and ergonomics when using 3D systems was evaluated using POMS questionnaire. The late results were assessed by recurrence rate, functional results — by Cleveland Clinic Constipation scale score, Incontinence scale score, P-Qol, and PGII.RESULTS: the study included 29 patients of the main and 32 patients of the control group. The follow-up was 21 ± 20.3 months. One complication developed in the control group (p = 1.0). The operation time in the main group was 74.1 ± 14 minutes (87.1 ± 24.3 minutes in controls, p = 0.01). The intraoperative blood loss was 19.8 ± 9.6 ml in the main group (55 ± 39.2 ml in controls, p = 0.001). The pain intensity was significantly lower in the main group (18.0 vs 22.5 points, p = 0.03). The volume of fluid collection 2–3 after surgery mesh site was 21.2 ± 9.7 cm3 in the main group (30.7 ± 25.6 cm3 in the control group, p = 0.02). The POMS scale assessment for a surgeon in the main group was 56.4 ± 33.5 points (87.3 ± 30.8 points in the control group). A follow-up examination 12 months postop revealed no recurrence in both groups (p = 1.0). The main and the control group showed no significant differences in functional outcomes.CONCLUSIONS: the use of 3D laparoscopic ventral mesh rectopexy for rectocele and rectal prolapse is comparable in late results with traditional laparoscopic procedure. However, it takes less operation time, lower pain intensity, less intraoperative blood loss, smaller fluid collection at mesh site, better comfort and ergonomics for surgeon.

Abstract Background This present study is aimed to retrospectively assess the efficacy of three-dimensional (3D) printing assisted osteotomy guide plate in accurate osteotomy of adolescent cubitus varus deformity. Material and methods Twenty-five patients (15 males and 10 females) with the cubitus varus deformity from June 2014 to December 2017 were included in this study and were enrolled into the conventional group (n = 11) and 3D printing group (n = 14) according to the different surgical approaches. The operation time, intraoperative blood loss, osteotomy degrees, osteotomy end union time, and postoperative complications between the two groups were observed and recorded. Results Compared with the conventional group, the 3D printing group has the advantages of shorter operation time, less intraoperative blood loss, higher rate of excellent correction, and higher rate of the parents’ excellent satisfaction with appearance after deformity correction (P < 0.001, P < 0.001, P = 0.019, P = 0.023). Nevertheless, no significant difference was presented in postoperative carrying angle of the deformed side and total complication rate between the two groups (P = 0.626, P = 0.371). Conclusions The operation assisted by 3D printing osteotomy guide plate to correct the adolescent cubitus varus deformity is feasible and effective, which might be an optional approach to promote the accurate osteotomy and optimize the efficacy.

AbstractWe aim to determine the impact of an artificial liver support system (ALSS) treatment before liver transplantation (LT), and identify the prognostic factors and evaluate the predictive values of the current commonly used ACLF prognostic models for short-term prognosis after LT. Data from 166 patients who underwent LT with acute-on-chronic liver failure (ACLF) were retrospectively collected from January 2011 to December 2018 from the First Affiliated Hospital of Zhejiang University School of Medicine. Patients were divided into two groups depending on whether they received ALSS treatment pre-LT. In the observation group, liver function tests and prognostic scores were significantly lower after ALSS treatment, and the waiting time for a donor liver was significantly longer than that of the control group. Both intraoperative blood loss and period of postoperative ICU care were significantly lower; however, there were no significant differences between groups in terms of total postoperative hospital stays. Postoperative 4-week and 12-week survival rates in the observation group were significantly higher than those of the control group. Similar trends were also observed at 48 and 96 weeks, however, without significant difference. Multivariate Cox regression analysis of the risk factors related to prognosis showed that preoperative ALSS treatment, neutrophil–lymphocyte ratio, and intraoperative blood loss were independent predicting factors for 4-week survival rate after transplantation. ALSS treatment combined with LT in patients with HBV-related ACLF improved short-term survival. ALSS treatment pre-LT is an independent protective factor affecting the 4-week survival rate after LT.

Abstract Background A diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes. Methods This single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed. Results The study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04). Conclusions PEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.
