Reasons and Risk Factors for Failed Same-Day Discharge After Total Joint Arthroplasty

BackgroundA shift toward same-day discharge (SDD) in primary elective total knee arthroplasty (TKA) and total hip arthroplasty (THA) has created a need to optimize patient selection and improve same-day recovery pathways. The objectives of this study were (1) to identify our institution’s most common causes for failed SDD, and (2) to evaluate risk factors associated with failed SDD. MethodsA retrospective review of SDD patients undergoing primary TKA or THA from January 2021 to September 2022 was conducted. Reasons for SDD failure were recorded and differences between successful and failed SDD cases were assessed via a multivariate logistic regression. ResultsOverall, 85.3% (651 of 753) of patients included were successful SDDs. Failed SDD occurred in 16.8% (74 of 441) of TKA and 11.8% (38 of 322) of THA cases. Primary reasons included failure to clear physical therapy (33.0%, 37 of 112), postoperative hypotension (20.5%, 23 of 112), and urinary retention (16.9%, 19 of 112). Analysis revealed that overall failed SDD cases were more likely to have had prior opioid use and a longer surgical time. Failed TKA SDD cases were more likely to have had a longer surgical time and not have receive a preoperative nerve block, while failed THA SDD cases were more likely to be older. ConclusionsThe SDD selection criteria and pathways continue to evolve, with multiple factors contributing to failed SDD. Improving patient selection algorithms and optimizing post-operative pathways can enhance the ability to successfully choose SDD candidates. Level of EvidenceIII.

Feasibility and safety of planned early discharge following laparotomy in gynecologic oncology with enhanced recovery protocol including opioid-sparing anesthesia.

This study aims to evaluate the feasibility and safety of planned postoperative day 1 discharge (PPOD1) among patients who undergo laparotomy (XL) in the department of gynecology oncology utilizing a modified enhanced recovery after surgery (ERAS) protocol including opioid-sparing anesthesia (OSA) and defined discharge criteria. Patients undergoing XL and minimally invasive surgery (MIS) were enrolled in this prospective, observational cohort study after the departmental implementation of a modified ERAS protocol. The primary outcome was quality of life (QoL) using SF36, PROMIS GI, and ICIQ-FLUTS at baseline and 2- and 6-week postoperative visits. Statistical significance was assessed using the two-tailed Student's t-test and non-parametric Mann-Whitney two-sample test. Of the 141 subjects, no significant demographic differences were observed between the XL group and the MIS group. The majority of subjects, 84.7% (61), in the XL group had gynecologic malignancy [vs. MIS group; 21 (29.2%), p < 0.001]. All patients tolerated OSA. The XL group required higher intraoperative opioids [7.1 ± 9.2 morphine milligram equivalents (MME) vs. 3.9 ± 6.9 MME, p = 0.02] and longer surgical time (114.2 ± 41 min vs. 96.8 ± 32.1 min, p = 0.006). No significant difference was noted in the opioid requirements at the immediate postoperative phase and the rest of the postoperative day (POD) 0 or POD 1. In the XL group, 69 patients (73.6%) were successfully discharged home on POD1. There was no increase in the PROMIS score at 2 and 6 weeks compared to the preoperative phase. The readmission rates within 30 days after surgery (XL 4.2% vs. MIS 1.4%, p = 0.62), rates of surgical site infection (XL 0% vs. MIS 2.8%, p = 0.24), and mean number of post-discharge phone calls (0 vs. 0, p = 0.41) were comparable between the two groups. Although QoL scores were significantly lower than baseline in four of the nine QoL domains at 2 weeks post-laparotomy, all except physical health recovered by the 6-week time point. PPOD1 is a safe and feasible strategy for XL performed in the gynecologic oncology department. PPOD1 did not increase opioid requirements, readmission rates compared to MIS, and patient-reported constipation and nausea/vomiting compared to the preoperative phase.

Gastrointestinal thickness, duration, and leak pressure of five intestinal anastomosis techniques in cats.

To compare time to construct completion and resistance to leakage for five intestinal anastomosis techniques in cats and to report normal feline gastrointestinal thickness. Experimental study. Grossly normal intestinal segments (n = 120) from 10 fresh cat cadavers. A total of 8 cm segments of fresh feline cadaveric intestine were collected, and mural thickness was recorded. Segments were randomly allocated between a control group (n = 20 segments) and five treatment groups (20 segments/group with 2 segments/construct = 10 constructs per group): (1) hand-sewn anastomosis - simple interrupted (HSA-SI), (2) hand-sewn anastomosis - simple continuous (HSA-SC), (3) functional end-to-end stapled anastomosis (FEESA), (4) functional end-to-end stapled anastomosis with oversew (FEESA-O), (5) skin stapled anastomosis (SS). Time to construct completion, leakage location, initial leak pressure (ILP), and maximum intraluminal pressure (MIP) were compared. Mean mural thickness ± SD (mm) for the stomach, duodenum, jejunum, and ileum were 1.66 ± 0.28, 2.05 ± 0.18, 2.28 ± 0.30, and 2.11 ± 0.39, respectively. ILPs (mean ± SD) for HSA-SI (165 ± 122 mmHg), HSA-SC (149 ± 83), FEESA-O (63 ± 25, FEESA (84 ± 59), SS (77 ± 56), and control segments (>500) were compared. There was no statistically significant difference in ILP (p > .08) or MIP (p > .084) between any treatment groups. Nonoversewn FEESAs were 2.4 times faster to perform compared to oversewn FEESA and SS groups, and 4.7 times faster than HSA (p < .001). All anastomosis techniques provide resistance to leakage that is supraphysiological to that of the normal maximum intraluminal pressure. HSA take longer to complete than stapled anastomoses. All anastomotic techniques may be appropriate in cats. Hand-sewn anastomoses result in a longer surgical time.

The Effect of Surgical Approach on Clinical Outcomes in 535 Patients with Remnant Gastric Cancer.

Purpose: This study aimed to evaluate the effect of laparoscopic gastrectomy (LG) and open gastrectomy (OG) on clinical outcomes in patients with remnant gastric cancer (RGC). Materials and Methods: The databases of PubMed, EMBASE, and Cochrane Library were used to search for eligible studies from inception to April 1st, 2023. Hazard ratios (HRs), mean difference (MD), odds ratios (OR), and 95% confidence intervals (CIs) were pooled up to analyze. The Newcastle-Ottawa Scale (NOS) scores were used to evaluate the quality of the included studies. This study was performed with RevMan 5.3 (The Cochrane Collaboration, London, United Kingdom) software. Results: A total of 11 studies involving 535 RGC patients were included in this study. In terms of basic information, we found that the OG group had a higher American Society of Anesthesiologists (ASA) grade (≥2) (OR = 0.24, I2 = 54%, 95% CI = 0.08-0.71, P = .01) than the LG group. In terms of postoperative outcomes, we found that the LG group had longer operative time (MD = 33.95, I2 = 58%, 95% CI = 15.05-52.85, P < .01), shorter postoperative hospital stay (MD = 5.08, I2 = 84%, 95% CI = -9.74 to -0.42, P = .03), shorter length of incision (MD = -7.15, I2 = 94%, 95% CI = -10.99 to -3.31, P < .01), earlier food intake (MD = -3.09, I2 = 76%, 95% CI = -4.84 to -1.35, P < .01), and earlier time to first flatus (MD = -0.84, I2 = 0%, 95% CI = -1.09 to -0.59, P < .01). We found that there was no statistically significant difference in overall survival (HR = 0.96, I2 = 0%, 95% CI = 0.48-1.93, P = .92) between the LG group and the OG group. Conclusion: LG for RGC patients had longer surgical time, shorter postoperative hospital stay, shorter length of incision, earlier food intake, and earlier time to first flatus.

Predictive Model for Reintervention in Total Ankle Arthroplasty

Category: Ankle Arthritis Introduction/Purpose: Osteoarthritis (OA) of the tibiotalar joint is associated with a high degree of morbidity, being comparable with final stages of renal and heart failure. The incidence of OA of the tibiotalar joint is as high as 47.7 per 100,000 habitants, of whom most of them will need a surgical intervention to improve their quality of life. Up to date evidence supports the use of the total ankle arthroplasty for its management. A great effort has been made to elucidate the factors associated with failure of the total ankle prothesis, until now no attempt has been made to look for factors associated with the need of surgical reintervention, beyond revision of the prothesis. Methods: Prospective cohort study in patients with tibiotalar OA operated between 2015 and 2022, with a minimum follow-up of 12 months, excluding revision prothesis and lost to follow-up. Reintervention was considered as any complication, related to the prothesis, that needed a surgical intervention that was not planned. We performed a multivariate logistic regression model with 13 variables (diabetes, hypertension, tabaquism, age, etiology, hind foot alignment, subtalar OA, talonavicular OA, calcaneocuboid OA, pes planus, cavo varus, previous subtalar arthrodesis and surgical time). Confounding effect was assessed with the change of the odds ratio of the principal independent variable, by adding or subtracting potentially confounder variables into the model. The variables that were statistically non-significant and those variables that do not cause confusion effect, were discarded. Goodness of fit was evaluated using the Hosmer-Lemeshow test and the discrimination of the model with the ROC curve. The Kaplan-Meier curve was used for survival analysis. Results: 105 total ankle arthoplasties were included, the statistically significant variables were: take-down etiology OR = 171.73 (CI: 6.87 - 4294.95, p &lt; 0.01), post-traumatic etiology OR = 14.56 (CI: 1.98 - 107.04, p &lt; 0.01) and surgical time OR = 0.96 (CI: 0.92 - 0.99, p = 0.04), while age OR = 1.02 (CI: 0.96 - 1.09, p = 0.57) and cavo varus OR = 4.75 (CI: 0.71 - 31.93, p = 0.11), wereincluded in the model because of its confounding effect. Goodness of fit demonstrates that the data fit the model adequately (p = 0.84). The ROC curve demonstrates 89.03% discriminatory power. The survival rate at 8 years was 80.39%, median of survival rate was not determined, because longer follow-up was needed. Conclusion: The take-down and post-traumatic etiology can be considered as important risk factors for requiring a surgical reintervention. Patients with a take-down etiology that have a cavo varus deformity and higher age, have a higher risk to require a surgical reintervention. Longer surgical time can be considered as a protective factor for needing a surgical reintervention. At 8 years 20.61% of patients will need a surgical reintervention, related to their Total Ankle Arthroplasty.

Evaluation of the effect of previous endometriosis surgery on clinical and surgical outcomes of subsequent endometriosis surgery

PurposePatients often undergo repeat surgery for endometriosis, due to recurrent or residual disease. Previous surgery is often considered a risk factor for worse surgical outcome. However, data are scarce concerning the influence of subsequent endometriosis surgery.MethodsA retrospective study in a centre of expertise for endometriosis was conducted. All endometriosis subtypes and intra-operative steps were included. Detailed information regarding surgical history of patients was collected. Surgical time, intra-operative steps and major post-operative complications were obtained as outcome measures.Results595 patients were included, of which 45.9% had previous endometriosis surgery. 7.9% had major post-operative complications and 4.4% intra-operative complications. The patient journey showed a median of 3 years between previous endometriosis surgeries. Each previous therapeutic laparotomic surgery resulted on average in 13 additional minutes (p = 0.013) of surgical time. Additionally, it resulted in more frequent performance of adhesiolysis (OR 2.96, p < 0.001) and in a higher risk for intra-operative complications (OR 1.81, p = 0.045), however no higher risk for major post-operative complications (OR 1.29, p = 0.418). Previous therapeutic laparoscopic endometriosis surgery, laparotomic and laparoscopic non-endometriosis surgery showed no association with surgical outcomes. Regardless of previous surgery, disc and segmental bowel resection showed a higher risk for major post-operative complications (OR 3.64, p = 0.017 respectively OR 3.50, p < 0.001).ConclusionPrevious therapeutic laparotomic endometriosis surgery shows an association with longer surgical time, the need to perform adhesiolysis, and more intra-operative complications in the subsequent surgery for endometriosis. However, in a centre of expertise with experienced surgeons, no increased risk of major post-operative complications was observed.

Does Computer Navigation or Robotic Assistance Affect the Risk of Periprosthetic Joint Infection in Primary Total Knee Arthroplasty? A Propensity Score-Matched Cohort Analysis

BackgroundThe use of technology during total knee arthroplasty (TKA) has been associated with more accurate component position and less blood loss. Yet to date, the risk of developing prosthetic joint infection (PJI) associated with computer navigation (CN) or robotic assistance (RA) has not been thoroughly evaluated. This study used propensity score-matching (PSM) in a large cohort of primary TKA patients to compare the rate of PJI following conventional TKA (TKA) versus CN-TKA and RA-TKA. MethodsWe retrospectively reviewed 13,015 knees in 11,727 patients who underwent primary TKA at a single institution from 2018 to 2021. The cohort was stratified into TKA, CN-TKA, and RA-TKA groups. 1:1 PSM was applied to 11,834 patients. Propensity score-matching was performed using logistic regression accounting for age, sex, body mass index, Charlson Comorbidity Index (CCI) score, CCI components, and smoking status. Univariate and multivariable analyses were performed to evaluate differences in surgical time and PJI rate. ResultsSignificantly longer median operating times were noted in the RA-TKA group (14 minutes) compared to TKA (P < .001). The PJI rates among matched cohorts were similar among RA-TKA (0.3%), CN-TKA (0.3%), and conventional TKA (0.5%). Multivariable logistic regressions demonstrated that the use of robotic assistance (odds ratio (OR) = 0.5, P = .423) or computer navigation (OR = 0.61, P = .128) was not associated with increased risk of PJI when compared to conventional TKA. ConclusionsUse of computer navigation and robotic assistance during primary TKA are associated with longer surgical times, but no difference in PJI frequency within 90 days of surgery.

Reduction of Blood Loss by Means of the Cavitron Ultrasonic Surgical Aspirator for Thoracoscopic Salvage Anatomic Lung Resections.

In centrally located lung tumors, salvage pulmonary resections pose challenges due to adhesions between the pulmonary parenchyma, chest wall, and hilum. This study aimed to investigate the surgical outcomes associated with Cavitron Ultrasonic Surgical Aspirator (CUSA) usage in thoracoscopic salvage pulmonary resections. Patients with centrally located advanced-stage lung tumors who underwent salvage anatomic resections following systemic or radiotherapy were included. They were categorized into CUSA and non-CUSA groups, and perioperative parameters and surgical outcomes were analyzed. Results: The study included 7 patients in the CUSA group and 15 in the non-CUSA group. Despite a longer median surgical time in the CUSA group (3.8 h vs. 6.0 h, p = 0.021), there was a significant reduction in blood loss (100 mL vs. 250 mL, p = 0.014). Multivariate analyses revealed that the use of CUSA and radiotherapy had opposing effects on blood loss (β: -296.7, 95% CI: -24.8 to -568.6, p = 0.034 and β: 282.9, 95% CI: 19.7 to 546.3, p = 0.037, respectively). In conclusion, while using CUSA in the salvage anatomic resection of centrally located lung cancer may result in a longer surgical time, it is crucial in minimizing blood loss during the procedure.

Short-term outcomes following congenital heart surgery in children with Down syndrome

Background Children with Down syndrome (DS) differ from typical children because of many genetic-related aspects that may affect outcomes after congenital heart surgery. To date, there have been no studies on outcomes after congenital heart surgery on pediatric DS patients in Indonesia.&#x0D; Objective To determine outcomes and mortality in DS patients who underwent heart surgery at Dr. Cipto Mangunkusumo Hospital, Jakarta.&#x0D; Methods A prospective and retrospective cohort study was conducted in DS patients aged &lt;15 years who underwent heart surgery from July 2007 to April 2015. The control group were patients in the same age range without DS who underwent heart surgery for various types of heart defects.&#x0D; Results There were 57 DS and 43 non-DS patients during study period. The types of heart defects found in DS patients were atrioventricular septal defect (AVSD) and ventricular septal defect (VSD) in 18/57 (31.6%) patients each, tetralogy of Fallot (12/57; 21%), atrial septal defect (ASD) (4/57; 7%), patent ductus arteriosus (PDA) (4/57; 7%) and transposition of the great arteries with VSD (TGA-VSD) (1/57; 1.8%). DS patients showed an increased incidence of preoperative PH (63.1%) compared to non-DS patients (25.6%). Median duration of surgery was longer in DS [2.9 (range 0.5-5.8) hours] than in non-DS [2.2 (range 0.7-4.7) hours]. DS patients have a longer mean cardiopulmonary bypass duration [79.5 (SD 33.9) minutes] compared to non-DS [59.9 (SD 23.6) minutes], longer mean aortic cross-clamp duration [45.3 (SD 23.7) minutes] compared to non-DS [34.8 (SD 15.7)]. There were significant differences in the incidence of preoperative pulmonary hypertension, surgical time, duration of cardiopulmonary bypass (CPB), and length of the aortic cross-clamp in DS patients compared to non-DS (P&lt;0.05). Median length of ICU stay was 1.9 (range 0.6 to 34) days in DS and 1 (range 0.3 to 43) day in non-DS patients (P=0.373). Median duration of mechanical ventilation [19.9 (range 3-540) vs. 8 (range 3-600) hours (P=0.308)], rate of pulmonary complications [14/57 (24.6%) vs. 6/43 (14%) patients (P=0.216)], and incidence of sepsis [16/57 (28.1%) vs. 6/43 (14%) patients (P=0.143)] were not significantly different between DS and non-DS patients. However, complete atrioventricular (AV) block only occurred in DS patients [6/57 (10.5%)]. In the DS group, 5/57 (8.8%) patients died. There was no mortality in the non-DS group.&#x0D; Conclusion Morbidity and mortality after cardiac surgery in were higher in DS than in non-DS patients. DS patients may have problems related to preoperative PH, AV block, longer surgical time, duration of CPB, and aortic cross-clamp compared to non-DS.

A quantitative CT analysis of fibula inlayed in a massive allograft for femoral diaphysis reconstruction

IntroductionIn diaphyseal reconstructions for bone tumor resection, massive bone allografts (MBA) are historically regarded as the gold standard. However, these are not without complications, and they present an elevated risk of infection, nonunion and structural failure that increases over time as the graft remains largely avascular. To counteract this disadvantage, a combination of allograft with a vascularized fibula has been proposed. The aim of our study was to objectively review the results of combined vascularized fibula-allograft constructs compared to plain allograft reconstruction for bone defects in tumor patients and to assess fibular vitality predictive factors from imaging studies. Materials and methodsOur data was retrospectively reviewed for patients with femoral diaphysis reconstructions in the past ten years. Ten patients (six males and four females) with a mean average follow-up time of 43.80 months (range 20–83, SD 18.17) with combined graft (Group A) were included in the study. As a control group 11 patients (six males and five females) with a mean average follow-up of 56.91 months (range 7–118, SD 41.33) with a simple allograft reconstruction were analyzed (Group B). Demographic and surgical data, adjuvant therapy as well as complications were analyzed in both groups. Both groups were assessed with plain radiographs for bony fusion at the osteotomy sites. Patients in “Group A” had consecutive CT scans at 6 months and then annually to check for potential bone stock and bone density changes. We analyzed total bone density as well as incremental changes in three different areas of the reconstruction. This was done at two defined levels for each patient. Only patients with at least two consecutive CT scans were included in the study. ResultsThere were no statistical differences between the groups in terms of demographics, diagnosis or adjuvant therapy (p = 1.0). The mean average surgical time (599.44 vs 229.09) and mean average blood loss (1855.56 ml vs. 804.55 ml) were significantly higher in the combined graft group A (p < 0.001 and p = 0.01, respectively). The mean average length of resection (19.95 cm vs. 15.50 cm) was higher in the combined graft group (p = 0.04). The risk for non-union and infectious complication was higher in the allograft group, however, the difference was not significant (p = 0.09 and p = 0.66, respectively). The mean average time to union at junction sites was 4.71 months (range 2.5–6.0, SD 1.19) for cases of successful fibula transfer, 19.50 months (range 5.5–29.5, SD 12.49) for the three cases where we presumed the fibula was not viable and 18.85 months (range 9–60, SD 11.99) for the allograft group. The difference in healing time was statistically significant (p = 0.009). There were four cases of non-union in the allograft group.Seven out of ten patients in Group A exhibited incremental changes in all CT scan measured values. This difference was statistically significant already at 18 months from the index surgery (p = 0.008). The patients with a non-viable fibula had a smaller increase in the percentage of total bone density area measured in the CT scan compared to those patients with a successful fibula transfer (4.33, SD 2.52 vs. 52.29, SD 22.74, p = 0.008). The average bone density incremental increase in-between the fibula and allograft was different among patients with an unsuccessful fibula transfer (32.22, SD 10.41) and the ones with a viable fibula (288.00, SD123.74, p = 0.009). Bony bridges were observed in six cases of viable fibula and in none of the tree presumably dead fibulas (p = 0.03). The mean average MSTS score was higher for the subgroup of successful fibular transfer (26.7/30, SD 2.87) when compared to the group of non-viable fibular graft (17.00/30, SD 6.08) and this was also statistically significant (p = 0–007). ConclusionA viable fibula enhances incorporation of the allograft and decreases the risk for both structural failure as well as infectious complications. Viable fibula also contributes to better functional status of the recipient. Consecutive CT scans proved to be a reliable method for assessing fibular vitality. When no measurable changes are present at 18-month follow-up, we can declare the transfer unsuccessful with a good amount of certainty. These reconstructions behave as simple allograft reconstructions with analogue risk factors. The presence of either axial bridges between the fibula and allograft or newly formed bone on the inner surface of the allograft is indicative of a successful fibular transfer. The success rate of fibular transfer in our study was only 70% and skeletally mature and taller patients seem to be at increased risk for failure. The longer surgical times and donor site morbidity therefore warrant stricter indications for this procedure.

Longer Operative Time and the Use of Anticoagulants Are Associated With Increased Blood Loss in Elderly Patients Undergoing Arthroscopic Rotator Cuff Repair

To study the effects of rotator cuff tear size, operation time, and the use of anticoagulant on blood loss in elderly patients undergoing arthroscopic rotator cuff surgery. Patients aged older than 65 years who underwent arthroscopic rotator cuff repair with subacromial decompression at our hospital from January 2015 to December 2021 were identified. We measured hemoglobin levels preoperatively, postoperatively, and 7 days after surgery. First, subjects were divided according to the operation time (group I, <90 minutes; group II, <120 minutes; group III <150 minutes; and group IV, >150 minutes). Second, we classified the subjects by the size of the rotator cuff tear (group A, <3 cm; group B, <5 cm; and group C, >5 cm). Lastly, we categorized the subjects into 2 groups according to the use of anticoagulant medication. A total of 566 patients were included. The mean hemoglobin (Hgb) levels were 13.8 ± 1.4 g/dL preoperatively, 13.2 ± 1.4 g/dL postoperatively, and 12.8 ± 1.3 g/dL 7 days after surgery, and the differences among them were statistically significant (P < .001). The Hgb level changes 7 days after surgery showed a significant decrease in the group with a longer operation time, and the Hgb loss increased from group 1 to group 4 (P < .001). They did not show any difference in the Hgb levels among the groups according to the size of a cuff tear preoperatively, postoperatively, and 7 days after surgery. The subjects with anticoagulant use showed more decrease in Hgb levels between immediately after the surgery and 7 days after the surgery (P= .031). Still, both groups did not show a statistical difference in the Hgb level 7days after surgery (P= .115). In this study, blood loss after arthroscopic rotator cuff repair in elderly patients was greater than expected. Bleeding increased in elderly patients who had longer surgical times or were taking anticoagulant medications after surgery. Tear size was not associated with a decrease in Hgb levels. Level III, retrospective comparative study.

Outcomes of Osteosynthesis Versus Hemiarthroplasty in Elderly Patients With Arbeitsgemeinschaft Fur Osteosynthesefragen-Orthopedic Trauma Association (AO-OTA) 31A2 Hip Fractures.

Background Intertrochanteric femur fractures account for more than half of the cases of hip fractures. These injuries are among the most common fractures in elderly individuals. Elderly patients suffer from other comorbidities such as diabetes mellitus or hypertension and are prone to low surgical tolerance with increased postoperative morbidity and mortality. Although the ideal choice of treatment for intertrochanteric femur fractures in the elderly remains debatable, the use of hemiarthroplasty in elderly patients provides an early mobilization and decreased postoperative morbidity. In this study, we aimed to assess the functional outcomes of bipolar hemiarthroplasty and osteosynthesis in Arbeitsgemeinschaft Fur Osteosynthesefragen-Orthopedic Trauma Association (AO-OTA) 31A2 hip fractures using the Harris Hip Score. Methodology A total of 60 elderly patients with AO/OTA 31A2 hip fractures were divided into two groups and treated with bipolar hemiarthroplasty and osteosynthesis using proximal femoral nail (PFN). Functional scores were assessed at two months, four months, and six months postoperatively using the Harris Hip Score. Results The mean age of the patients was 73.03 ± 7.57 years in the study. The majority of the patients were females, 38 (63.33%), with 18 females in the osteosynthesis group and 20 females in the hemiarthroplasty group. The average operative time was 144.93 ± 9.76 minutes in the hemiarthroplasty group and 86.07 ± 11 minutes in the osteosynthesis group. Blood loss was 263.67 ± 42.95 mL in the hemiarthroplasty group and 84.5 ± 15.05 mL in the osteosynthesis group. The average Harris Hip Score at two months, four months, and six monthswas 64.77 ± 4.33, 72.67 ± 3.54, and 79.72 ± 2.53, respectively, for the hemiarthroplasty group and 57.83 ± 2.83, 64.13 ± 3.89, and 72.83± 3.89, respectively, for the osteosynthesis group (p < 0.001 for all follow-up scores). One death was encountered in the hemiarthroplasty group. Other complications included superficial infection noted in two(6.67%) patients in both groups. There was one episode of hipdislocation in the hemiarthroplasty group. Conclusions The use of bipolar hemiarthroplasty in intertrochanteric femur fractures in elderly patients can prove to be better in comparison to osteosynthesis, but the use of osteosynthesis can be effective for patients who cannot tolerate major blood loss and longer surgical times.

Effect of Trainee Level on Surgical Time and Postoperative Complications of Anterior Cruciate Ligament Reconstruction

The objective of this study was to investigate the association between trainee level and surgical time and postoperative complications of anterior cruciate ligament reconstruction (ACLR). A retrospective chart review of patients who underwent ACLR at an academic orthopaedic ambulatory surgery center collected demographic and clinical information, including the number of trainees present and trainee level. Unadjusted and adjusted regression analyses assessed the association between trainee number and level with surgical time (time from skin incision to closure) and postoperative complications. Of 799 patients in this study operated on by one of five academic sports surgeons, 87% had at least one trainee involved. The average surgical time overall was 93 ± 21 minutes and by trainee level was 99.7 (junior resident), 88.5 (senior residents), 96.6 (fellows), and 95.6 (no trainees). Trainee level was significantly associated with surgical time (P = 0.0008), with increased surgical time in cases involving fellows (0.0011). Fifteen complications (1.9%) were observed within 90 days of surgery. No notable risk factors of postoperative complications were identified. Resident trainee level does not have a notable effect on surgical time or postoperative complications for ACLR at an ambulatory surgery center, although cases involving fellows had longer surgical times. Trainee level was not associated with risk of postoperative complications.

Modifiable factors associated with a consistently high acute pain trajectory after surgical treatment of traumatic fractures in Ethiopia: a multi-center prospective cohort study

BackgroundIn Ethiopia, little is known about postoperative pain trajectories and possible predictive factors associated with them in patients undergoing surgery following traumatic fractures.MethodsThis multi-center prospective observational cohort study included surgical candidates for traumatic fractures (n = 218). Worst pain intensity was measured with an 11-point numeric rating scale on the first 4 postoperative days and day of hospital discharge. Growth mixture modeling was used to identify subgroups of patients based on their pain trajectories, and logistic regression models to quantify associations between pain trajectories and demographic, clinical, psychological, and life style factors.ResultsTwo postoperative pain trajectory subgroups were identified: rapid pain relief (48% of included individuals) and consistently high pain (52% of included individuals). Sub-analysis stratified by cause of injury demonstrated that higher preoperative pain was an independent risk factor for consistently high postoperative pain regardless of the patient’s injury type: traffic accident (OR = 1.48, 95% CI 1.23–1.79), machine/tool injury or conflict (OR = 1.58, 95% CI 1.11–2.26), or fall (OR = 1.47, 95% CI 1.08–1.99). Moreover, longer surgical time was a risk factor for consistently high postoperative pain among patients who had a fall-related injury (OR = 1.02, 95% CI 1.00–1.03). In contrast, among patients with a traffic-related injury, receiving a nerve block was a protective factor (OR = 0.19, 95% CI 0.04–0.87) compared with general anesthesia.ConclusionHigher preoperative pain and longer surgical time were associated with a consistently high acute postoperative pain trajectory. Clinicians may use these potentially modifiable factors to identify patients at risk for consistently high pain during the early postoperative period.

Hidden blood loss and its risk factors in percutaneous vertebroplasty surgery for osteoporotic vertebral compression fractures.

Percutaneous vertebroplasty (PVP) is a percutaneous interventional procedure for osteoporotic vertebral compression fractures (OVCFs). However, hidden blood loss (HBL) during the surgery is easily disregarded. This study aimed to evaluate HBL and its possible risk factors in the patients following PVP for OVCFs. Patients with OVCFs who underwent PVP surgery between January 2019 and November 2022 at our hospital were retrospectively analyzed. Patients' demographics, laboratory data, and imaging and clinical date were also collected. Preoperative and postoperative hematocrit were recorded, the hidden blood loss was calculated according to Sehat formula, and the risk factors were analyzed by multivariate linear regression analysis. One hundred and fifty-five patients (26 males and 129 females) were retrospectively enrolled in this study. 85.2% of patients had one segment vertebral fracture and the mean surgical time was 30.5 ± 11.0min. No intraspinal cement leakage occurred. The mean HBL was 204.0 ± 89.6ml. Multivariate linear regression analysis revealed that HBL was positively associated with number of fracture segments (P = 0.001), degree of vertebral height restoration (P = 0.001), surgical time (P = 0.000), number of puncture (P = 0.002), and cement leakage (P = 0.038). Multiple vertebral fractures, higher degree of vertebral height restoration, longer surgical time, more number of puncture, and cement leakage are independent risk factors for HBL. Therefore, HBL should not be neglected in the patients with OVCFs undergoing PVP surgery, especially in those with poor preoperative physical condition and presence of anemia.

Robotic versus open approach in total gastrectomy for gastric cancer: a comparative single-center study of perioperative outcomes.

The robotic approach to gastric cancer has been gaining interest in recent years; however, its benefit over the open procedure in total gastrectomy with D2 lymphadenectomy is still controversial. The aims of the study were to compare postoperative morbidity and mortality, hospital stay, and anatomopathological findings between the robotic and open approaches to oncologic total gastrectomy. We analyzed a prospectively collected database, which included patients who underwent total gastrectomy with D2 lymphadenectomy in our center using a robotic or an open approach between 2014 and 2021. Comparative analysis of clinicopathological, intraoperative, postoperative and anatomopathological variables between the robot-assisted group and the open group was performed. Thirty patients underwent total gastrectomy with D2 lymphadenectomy by a robotic approach and 48 patients by an open procedure. Both groups were comparable. The robot-assisted group presented a lower rate of Clavien-Dindo complications ≥ stage II (20 vs. 48%, p = 0.048), a shorter hospital stay (7days vs. 9days, p = 0.003) and had a higher total number of lymph nodes resected (22 nodes vs. 15 nodes, p = 0.001) compared to the open approach. Operative time was longer in the robotic group (325min vs. 195min, p < 0.001) compared to the open group. The robotic approach is associated with a longer surgical time, a lower rate of Clavien-Dindo complications ≥ stage II and a shorter hospital stay, and more lymph nodes were resected compared to the open approach.

High preoperative HbA1c does not affect early or late complication rates after bariatric surgery.

Preoperative HbA1c has been associated with an increased incidence of postoperative morbidity and mortality after abdominal and cardiovascular surgery. The literature on bariatric surgery is inconclusive and guidelines recommend postponement of surgery when HbA1c is above an arbitrary threshold (≥ 8.5%). In this study, we sought to understand the impact of preoperative HbA1c on early and late postoperative complications. We performed a retrospective analysis of prospectively collected data on obese patients with diabetes who underwent laparoscopic bariatric surgery. Patients were categorized into three groups according to their preoperative HbA1c level: < 6.5% (group 1), 6.5-8.4% (group 2) and ≥ 8.5% (group 3). Primary outcomes were early and late postoperative complications (< and > 30days, respectively) that were differentiated based on severity (major/minor). Secondary outcomes were length of stay (LOS), duration of surgery, and rate of readmission. In total, 6798 patients underwent laparoscopic bariatric surgery from 2006 to 2016, of which 1021 (15%) patients had Type 2 Diabetes (T2D). Complete data with a median follow-up of 45months (3-120) were available for 914 patients with HbA1c < 6.5% (n = 227, 24.9%), 6.5-8.4% (n = 532, 58.5%) and ≥ 8.5% (n = 152, 16.6%). Early major surgical complication rate was similar across the groups ranging from 2.6 to 3.3%. No associations between high preoperative HbA1c and late complications-medical as well as surgical-was observed. Groups 2 and 3 had statistically significant more pronounced inflammatory status. LOS (1.8-1.9days), readmission rates (1.7-2.0%) and surgical time was similar across the three groups. Elevated HbA1c is not associated with more early or late postoperative complications, longer LOS, longer surgical time or higher rates of readmission.

Overweight increases perioperative spinal surgery complications: a single-center retrospective study

BackgroundThe World Health Organization (WHO) defines a person with a body mass index (BMI) greater than or equal to 25 kg/m2 as overweight. Being overweight is a lifestyle-related disease; however, little is known about the impact of overweight on the perioperative complications of orthopedic surgery. This study aimed to define the effect of overweight on the perioperative complications of spinal surgery.MethodsThis retrospective case series study reviewed 269 consecutive patients who underwent spinal surgery. These patients were divided into the overweight (OW) and non-overweight (NOW) groups. Age, BMI, surgical time, blood loss, and perioperative complications were evaluated and compared between the groups.ResultsThere were 117 patients (43%) in the OW group and 152 (57%) in the NOW group. Cervical surgery was performed in 72 cases, thoracic surgery in 34, and lumbosacral surgery in 159. The surgical time was significantly longer in the OW group than in the NOW group (204.6 ± 98 min vs. 175 ± 75 min; p = 0.01). Blood loss was greater in the OW group than in the NOW group (446.8 ± 447.9 mL vs. 279 ± 296.5 mL; p = 0.00). Durotomy was more frequent in the OW group than in the NOW group (10 vs. 3 cases; p = 0.02). There was no difference in complications other than durotomy.ConclusionsOW patients had longer surgical time, more blood loss, and more frequent durotomy than NOW patients. These findings indicate that overweight increases perioperative complications of spinal surgery.

Comparison of surgical and obstetric outcomes in women with uterine leiomyomas after laparoscopic vs. abdominal myomectomy: A single-center cohort study.

Our aim was to study the advantages, complications and obstetrical outcomes of laparoscopic myomectomy (LM) compared with abdominal myomectomy (AM). We conducted a retrospective cohort study at La Paz University Hospital that included LMs and AMs performed between 2012 and 2018, analyzing 254 myomectomies (142 AMs [55.7%] and 112 LMs [43.9%]). The mean number of fibroids was 1.8 ± 1.5 and 3 ± 2.9 for the LM and AM groups, respectively (p < 0.006). The mean size of the largest myoma was 7.6 cm ± 2.7 cm and 10.2 cm ± 5.4 cm for the LM and AM groups, respectively (p < 0.001). LMs were associated with longer surgical times (p < 0.001) and shorter hospitalizations (p = 0.001). There were no significant differences in the intraoperative and postoperative complication rates (p = 0.075 and p = 0.285 for LM and AM, respectively). The subsequent pregnancy rate was higher for the LM group (30.8% vs. 16.8%, p = 0.009), with a vaginal delivery rate of 69% and no cases of uterine rupture.
