Three-Pillar Expansive Craniotomy in Children with Acute Ruptured Supratentorial Brain Arteriovenous Malformations.

OBJECTIVE: Acute rupture and hemorrhage of pediatric brain arteriovenous malformations (AVMs) may lead to cerebral herniation or intractable intracranial hypertension, necessitating emerging surgical interventions to alleviate intracranial pressure. However, there is still controversy regarding the timing of treatment for ruptured AVMs. This study aimed to assess the feasibility of utilizing three-pillar expansive craniotomy (3PEC) at different times during the treatment of pediatric ruptured supratentorial AVMs. METHODS: A retrospective analysis was conducted on all consecutive cases of acute rupture in supratentorial AVM children who underwent 3PEC at a single institution from 2020 to 2022. General information, clinical characteristics, radiological data, and prognosis were reviewed and analyzed. RESULTS: Thirteen children were included in the analysis. The intracranial pressure of all patients decreased to below 15 mmHg within 10 days. The expansion volume of the cranial cavity of the patients increased by 18.3 cm3 (95% confidence interval, 10.2-26.3; P < 0.001) compared to the hematoma volume. None of the patients required decompressive craniectomy due to intractable intracranial hypertension caused by cerebral swelling. The median waiting period for patients with delayed AVMs treatment was 8 days, during which no rebleeding occurred. CONCLUSIONS: Emergency intervention with 3PEC in children experiencing acutely ruptured supratentorial AVMs appears to be feasible. For children requiring delayed management of the AVMs, 3PEC may diminish the risk of rebleeding during the waiting period and shorten the waiting period.

Partial nephrectomy after a period of active surveillance: Are perioperative and pathology outcomes worsened compared to immediate surgery?

INTRODUCTION: Active surveillance (AS) is a viable strategy for managing small renal masses (SRMs) in lieu of immediate surgery, but concerns persist regarding its impact on delayed partial nephrectomy (PN) outcomes. We aimed to compare perioperative and pathological outcomes of patients initially on AS for SRMs, later undergoing PN, against those undergoing immediate PN. MATERIALS AND METHODS: Data were extracted from a prospective institutional database (January 2018-September 2023) for patients with cT1a renal masses. Only malignancies confirmed at final pathology were included. Baseline patient and tumor characteristics and the time from AS enrollment to PN were recorded. Surgical, renal functional, and final pathology outcomes were analyzed, including histology, tumor size, pT stage, upstaging rate, and positive surgical margins. Predictors of upstaging were identified using logistic regression models. RESULTS: Analysis included 356 patients: 307 immediate PN and 49 deferred PN after a median of 18 months in AS. Groups had comparable baseline characteristics; no significant differences emerged in surgical and postoperative outcomes. Final pathology revealed no significant disparities in tumor size, histology, positive margins, or upstaging, though pT stage distribution differed (2.4 % versus 4.3 % for pT3a, immediate versus deferred, p = 0.04). Univariable analysis identified RENAL Score (OR 1.29, 95 % C.I. 1.09-1.53, p = 0.003) and clinical tumor size (OR 1.16, 95 % C.I. 1.10-1.22, p < 0.01) as upstaging predictors, confirmed by multivariable analysis (p < 0.01). CONCLUSION: Our comparative analysis found no worsened perioperative or adverse pathological outcomes in patients with deferred PN, supporting the safety of this approach in managing SRMs, at least as an initial option.

Navigating appendicitis care during the Covid-19 pandemic: a retrospective cohort study in China.

BACKGROUND: The emergence of the COVID-19 pandemic in December 2019 initiated a global transformation in healthcare practices, particularly with respect to hospital management. PCR testing mandates for medical treatment seekers were introduced to mitigate virus transmission. AIMS: This study examines the impact of these changes on the management of patients with appendicitis. METHODS: We conducted a retrospective analysis of medical records for 748 patients diagnosed with appendicitis who underwent surgery at a tertiary care hospital during two distinct periods, the pre-pandemic year 2019 and the post-pandemic year 2021. Patient demographics, clinical characteristics, laboratory data, surgical outcomes, and hospital stay duration were assessed. RESULTS: While no significant differences were observed in the general characteristics of patients between the two groups, the time from hospital visit to operation increased significantly during the pandemic. Unexpectedly, delayed surgical intervention was associated with shorter hospital stays but did not directly impact complication rates. There was no discernible variation in the type of surgery or surgical timing based on symptom onset. The pandemic also prompted an increase in appendicitis cases, potentially related to coronavirus protein expression within the appendix. CONCLUSIONS: The COVID-19 pandemic has reshaped the landscape of appendicitis management. This study underscores the complex interplay of factors, including changes in hospital protocols, patient concerns, and surgical timing. Further research is needed to explore the potential link between COVID-19 and appendicitis. These insights are valuable for informing healthcare practices during and beyond the pandemic.

Delayed Fixation of Acetabular Fractures Affects Functional Outcomes and Health-Related Quality of Life, Not Just Quality of Reduction.

Background: Delayed operative fixation of acetabular fractures remains a major problem in many parts of the world. No previous studies have reported the effect of fixation delay on health-related quality of life (HRQOL). We aimed to investigate the effect of delayed operative fixation of acetabular fractures on health-related quality of life, EuroQol-5 Dimension questionnaire (EQ-5D), and other related outcomes. Methods: We retrospectively analysed 117 patients who underwent open reduction internal fixation for displaced acetabular fractures between 2014 and 2021. Patients were divided into groups based on the admission-to-surgery time (interval between injury and definitive surgery): 1-14, 15-21, and >21 days. Patients were analysed for associations between admission-to-surgery time and postoperative outcomes, including operative time, estimated blood loss, blood transfusion, postoperative complication, and quality of reduction. Eighty-five patients with a mean follow-up time of 3.94 ± 1.84 years were analysed for the association between admission-to-surgery time and conversion to total hip arthroplasty, the Modified Merle d'Aubigné and Postel score, EQ-5D score, ability to sit cross-legged, and ability to sit squat. Multivariable linear regression was used for continuous outcomes and logistic regression for categorical outcomes associated with delayed operative fixation. Results: An admission-to-surgery time > 14 days was associated with significantly higher blood loss [785 mL (236-1335), p = 0.006]. For associated fractures, an admission-to-surgery time > 21 days increased the risk of poor reduction [odds ratio (OR), 5.21 (1.42-19.11), p = 0.013]. Further, admission-to-surgery time > 21 days was associated with poor Modified Merle d'Aubigné and Postel scores [OR, 8.46 (1.48-48.29), p = 0.016], EQ-5D pain domain [OR, 3.55 (1.15-11), p = 0.028], and EQ-5D usual activity domain [OR, 4.24 (1.28-14), p = 0.018]. Conclusion: Delayed operative fixation of acetabular fractures after 21 days affected the functional outcomes and HRQOL, independent of the reduction status. Surgical interventions and patient referrals should occur at the earliest and within 21 days from the time of injury.

Survival benefits of the wait-and-grow approach in small babies (≤2000 g) requiring heart surgery.

Objective: The best approach to minimize the observed higher mortality of newborn infants with low birth weight who require congenital heart surgery is unclear. This retrospective study was designed to review outcomes of newborn infants weighing <2000 g who have undergone cardiovascular surgery to identify patient parameters and clinical strategies for care associated with higher survival. Methods: A retrospective chart review of 103 patients who underwent cardiovascular surgery from 2010 to 2021 who were identified as having low birth weight (≤2000 g). Patients who underwent only patent ductus arteriosus ligation or weighing >3500 g at surgery were excluded. Results: Median age was 24 days and weight at the time of surgery was 1920 g. Twenty-six (25%) operative mortalities were recorded. Median follow-up period was 2.7 years. The 1- and 3-year overall Kaplan-Meier survival estimate was 72.4% ± 4.5% and 69.1% ± 4.6%. The 1-year survival of patients who had a weight increase >300 g from birth to surgery was far superior to the survival of those who did not achieve such a weight gain (81.4% ± 5.6% vs 64.0% ± 6.7%; log-rank P = .04). By multivariable Cox-hazard regression analysis, the independent predictor of 1-year mortality was genetic syndrome (hazard ratio, 3.54; 95% CI, 1.67-7.82; P < .001), whereas following a strategy of increasing weight from birth to surgery resulted in lower mortality (hazard ratio, 0.49; 95% CI, 0.24-0.90; P = .02). Conclusions: A strategy of wait and grow for newborn infants with very low birth weight requiring heart surgery results in better survival than immediate surgery provided that the patient's condition allows for this waiting period.

Delayed Meniscus Repair Lowers the Functional Outcome of Primary ACL Reconstruction.

BACKGROUND: Our purpose was to evaluate whether the time of intervention and the type of meniscus surgery (repair vs. partial meniscectomy) play a role in managing anterior cruciate ligament (ACL) reconstructions with concurrent meniscus pathologies. METHODS: We performed a prospective cohort study which differentiated between early and late ACL reconstructions with a cut-off at 3 months. Patients were re-evaluated after 2 years. RESULTS: Thirty-nine patients received an operation between 2-12 weeks after the injury, and thirty patients received the surgery between 13-28 weeks after trauma. The strongest negative predictive factor of the International Knee Documentation Committee subjective knee form in a hierarchical regression model was older age (ß = -0.49 per year; 95% CI [-0.91; -0.07]; p = 0.022; partial R2 = 0.08)). The strongest positive predictive factor was a higher preoperative Tegner score (ß = 3.6; 95% CI [0.13; 7.1]; p = 0.042; partial R2 = 0.07) and an interaction between meniscus repair surgery and the time of intervention (ß = 27; 95% CI [1.6; 52]; p = 0.037; partial R2 = 0.07), revealing a clinical meaningful difference as to whether meniscus repairs were performed within 12 weeks after trauma or were delayed. There was no difference whether partial meniscectomy was performed early or delayed. CONCLUSIONS: Surgical timing plays a crucial role when surgeons opt for a meniscus repair rather than for a meniscectomy.

Delayed surgery for acute type A aortic dissection: a retrospective review of an alternative surgical strategy in the COVID-19 era.

BACKGROUND: During the coronavirus disease (COVID-19) pandemic, medical resources have often been limited to emergency surgeries. This study aimed to evaluate our experience with delayed surgery for acute type A aortic dissections (ATAADs). METHODS: A retrospective study was conducted on 33 patients who underwent surgery for ATAADs between January 2020 and December 2021. The patients were divided into two groups: patients treated within 12 h of arrival (E group; N = 21) and those treated > 12 h after arrival (D group; N = 12) with strict antihypertensive therapy until surgery. RESULTS: The plasma fibrinogen levels on arrival were lower in the D group than in the E group (174.3 ± 109.1 vs 293.4 ± 165.4, p = 0.038). The time to surgery from symptom onset was longer in the D group than in the E group (4 ± 1 h vs. 86 ± 108 h, p < 0.001). There was one case (3%) of mortality and seven cases (21%) of cerebral infarctions in the E group. There was no significant difference in the intraoperative data and quantity of blood transfused between the two groups. CONCLUSION: Thus, delayed surgery for ATAAD with appropriate preoperative management may be an alternative surgical strategy in the COVID-19 era.

Does delay from injury to surgery increase the risk of dislocation of a hip hemiarthroplasty?

Dislocation of a hip hemiarthroplasty used to treat a hip fracture is a serious complication. The aim of this study was to identify whether a delay in the time from fracture to surgery causes an increase in the rate of post-operative hip dislocation. From a single center, data from intracapsular neck of femur patients treated with hip hemiarthroplasty was collected between October 1986 to August 2021. The time from both fall to surgery and admission to surgery was recorded. Surviving patients were followed up for one year. The overall dislocation rate was 51 out of 4155 patients (1.2%). The 3019 patients who had surgery within two days of the injury had a lowest dislocation rate (29 dislocations, 0.96%). For the 197 patients with no history of a fall, there were 5 (2.5%) dislocations (p=0.036, 95% confidence interval of difference 0.15 to 0.97 for comparison with surgery within two days). For the 399 patients with a delay of more than four days from injury till surgery, there were nine dislocations (2.3%) (p=0.045, 95% confidence intervals of difference 0.20 to 0.89 for comparison with surgery within two days). This study demonstrates an increase in the risk of dislocation for those patients with no history of a fall and those with a delay of more than four days from injury to surgery.

Traumatic rotator cuff injury: does delayed surgery worsen functional outcomes?

PURPOSE: The optimal timing of surgery after traumatic rotator cuff tears (RCT) is unclear, with its impact on functional outcomes under debate. This study aimed to review functional outcomes after RCT repair in patients who underwent early vs delayed surgery at our unit. METHODS: This was single-centre retrospective evaluation. Patients with an acute traumatic RCT that underwent repair between 2017 and 2019 and had local follow-up were included and placed into two groups: early surgery (within 6 months from injury) and delayed surgery (more than 6 months from injury). Patient demographics, RCT data and pre- and post-operative (after 12 months) Oxford Shoulder Score (OSS) were extracted from medical records. Data was analysed to compare OSS scores between groups, as well as the effect of cuff tear sizes on OSS scores. RESULTS: Forty-nine patients were included in the analysis (15 early, 34 delayed). There were no significant differences in age, sex or cuff tear sizes between groups. No difference was identified in the mean post-operative OSS between early vs delayed groups (40.9 ± 6.34 vs 40.5 ± 7.65, p = 0.86). The mean improvement in OSS after surgery was also similar between groups (22.5 ± 7.81 vs 20.97 ± 7.19, p = 0.498). Having a large or massive RCT did not worsen OSS compared to small or medium RCT (p = 0.44), even when stratified by early or delayed surgery. CONCLUSION: Delayed surgery for traumatic RCT greater than 6 months from injury did not negatively impact long-term functional outcomes at our unit. Patients should be reassured as applicable before surgery in the event of prolonged or unavoidable delays.

The Time-Effect Relationship between Time to Surgery and In-Hospital Postoperative Pneumonia in Older Patients with Hip Fracture.

INTRODUCTION: Pneumonia is a common and devastating complication following hip fracture surgery in older patients. Time to surgery is a potentially modifiable factor associated with improved prognosis, and we aim to quantify the time-effect relationship between time to surgery and in-hospital postoperative pneumonia (IHPOP) and identify the effect of delayed surgery on the risk of IHPOP. METHODS: We analyzed clinical data of older hip fracture patients (≥60 years) undergoing surgical treatments at a tertiary referral trauma center between 2015 and 2020. Restricted cubic spline (RCS) was used to fit the time-effect relationship between time to surgery and IHPOP. Based on the results of RCS, we divided patients into two groups of "early surgery" and "delayed surgery." A 1:1 propensity score matching (PSM) analysis and multivariate conditional logistic regression analysis were performed to minimize the selection bias and determine the association magnitude. Subgroup analysis was conducted to assess potential interaction effects between delayed surgery and common risk factors for IHPOP. RESULTS: 3,118 eligible patients were included. The RCS curve showed an inverse S-shape trend and the relative risk of IHPOP decreased in the range of days 2-3 and increased on day 1 and day 3 or more post-injury, with the lowest point on day 3. PSM yielded 1,870 matched patients and delayed surgery (>3 days) was identified to be independently associated with IHPOP (relative ratio, 1.66; 95% confidence interval, 1.12-2.46; p value, 0.011). We observed positive interaction effects between delayed surgery and age of 80 years or more, female gender, COPD, heart disease, ASA score ≥3, anemia, and hypoproteinemia. CONCLUSION: The relative risk of IHPOP decreased in the range of 2-3 days and increased on day 1 and day 3 or more post-injury. Delayed surgery (>3 days) was identified to be independently associated with a 1.66-fold increased risk of IHPOP.

Effects of prolonged waiting time on visual outcomes of patients with pediatric cataract in a Tertiary Public Hospital

Background@#Pediatric cataract is one of the most common preventable cause of childhood blindness worldwide. Early and timely intervention of pediatric cataract is important to maximize the visual outcomes and start prompt visual rehabilitation.@*Objectives@#This study aimed to determine the average time from the day of initial consult at the outpatient clinic to the day of the cataract surgery and compare the effects of delayed surgery on visual outcomes of patients.@*Methods@#This is a retrospective chart review of medical records from January 2015 to June 2022. The dates of the different steps in the process up to the day of intervention were noted and the average interval duration and the total waiting time were determined. Patients operated on within 2 weeks from initial consult was defined as no delay while those operated >2 weeks had delayed surgery. Pre-operative and post-operative best corrected log MAR visual acuity were compared within each group to determine if delay in surgical intervention has a significant effect on the visual outcomes of patients.@*Results@#Median age at initial consult was 4.9 years while median age at surgery was 5.2 years. Ninety-nine (99) patients had developmental cataract and 123 patients had bilateral cataract. Leukocoria was the most common chief complaint (63.45%). Pre-operatively, 94 patients had strabismus, 49 had eye preference, 48 had nystagmus, and 43 had amblyopia in the diagnosis. There was significantly faster admission to cataract surgery during the pandemic compared to pre-pandemic period but there was no difference in the total waiting time. Patients with congenital cataract had the least total waiting time followed by developmental, and rubella cataract. There is no significant difference in visual outcomes between patients operated without delay and with delay.@*Conclusion@#There is delayed age at diagnosis and surgery of pediatric cataract patients in the Philippine General Hospital. Early surgery did not reflect better visual outcomes compared to delayed surgery probably due to delay in consultation of patients.

Clinicopathological Outcomes in Patients With Locally Advanced Rectal Cancer Undergoing Preoperative Short-Versus Long-course Chemoradiotherapy With Delayed Surgery.

BACKGROUND/AIM: We aimed to compare the clinicopathological outcomes in patients with locally advanced rectal cancer after short- or long-course concurrent chemoradiotherapy (CCRT) followed by delayed surgery. PATIENTS AND METHODS: The records of 94 patients with cT3-4N0-2M0 rectal cancer who received CCRT between 2010 and 2017 were reviewed. Short-course radiotherapy (RT) was delivered with a median total dose of 25 Gy in five fractions (n=27), and long-course RT was delivered with a median total dose of 50.4 Gy in 28 fractions (n=67). The following concurrent chemotherapy regimens were administered: 5-fluorouracil plus leucovorin in 58 and capecitabine in 24; in 12 cases agents were unknown. The median interval between CCRT and surgery was 8 weeks. Adjuvant chemotherapy was administered after surgery in 80 patients (5-fluorouracil plus leucovorin, n=54; capecitabine, n=9; other, n=14; and unknown, n=3). Propensity-score matching analysis was conducted. RESULTS: The median follow-up duration was 4.3 years. There were no statistically significant differences between the short- and long-course RT groups in sphincter preservation (85.2% vs. 92.5%, p=0.478), pathological complete remission (18.5% vs. 14.9%, p=0.905), downstaging (44.4% vs. 26.9%, p=0.159), and negative circumferential resection margin (92.6% vs. 89.6%, p=0.947) rates. No differences were found in survival outcomes between the short- and long-course groups at 3 years (overall survival: 91.8% vs. 88.1%, p=0.790; disease-free survival, 75.2% vs. 72.5%, p=0.420; locoregional relapse-free survival, 90.5% vs. 98.4%, p=0.180; and distant metastasis-free survival, 79.6% vs. 73.5%, p=0.490). Similar results were observed after PSM. CONCLUSION: Clinically, short-course CCRT may be a feasible alternative to long-course CCRT in patients with locally advanced rectal cancer.

Optimal Timing of Laparoscopic Cholecystectomy After Conservative Therapy for Acute Cholecystitis.

Background/Aim: According to the Tokyo Guidelines 2018, the operation for acute cholecystitis is recommended to be performed as early as possible. However, there are cases in which early surgeries cannot be performed due to complications of patients or facility conditions, resulting in elective surgery. Hence, we retrospectively analyzed elective surgery cases in this study. Patients and Methods: There were 345 patients who were underwent laparoscopic cholecystectomy (LC) at our hospital from January 2019 to December 2020 in this retrospective study. A total of 83 patients underwent LC more than 3 days after conservative treatment. The elective LC patients were divided into the Early group (4-90 days after onset, n=36) and the Delayed group [91 days or more (13 weeks or more) after onset, n=31], excluding 16 patients who underwent percutaneous transhepatic gallbladder drainage. Results: As for operative time, there was a significant difference between the Delayed and Early groups (91.2 vs. 117 minutes, p=0.0108). And also, there was a significant difference in the postoperative hospital stay, which was significantly shorter in the Delayed group than in the Early group (3.4 vs. 5.9 days, p=0.0436). Although there were no significant differences in either conversion rates or complication rates, both of these were decreasing in the Delayed group. In particular, there were no complications in the Delayed group. Conclusion: When the conservative treatment for acute cholecystitis precedes and precludes urgent/early LC within 3 days, delaying LC for at least 91 days (13 weeks or more) after onset could reduce operative time and postoperative hospital stay. Moreover, there would be no complications after LC, and the rates of conversion during LC may be kept low.

Delayed Surgical Treatment in Patients with Chronic Carpal Tunnel Syndrome Is Still Effective in the Improvement of Hand Function.

Background and Objectives: Severe carpal tunnel syndrome (CTS) is the most common compression neuropathy in the upper extremities treated conservatively; later, when advanced, CTS is treated mostly surgically. The most prevalent symptoms comprise numbness, as well as sensation loss in the thumb, index, and middle finger, and thenar muscle strength loss, resulting in impaired daily functioning for patients. Data on the results of CTS treatment in patients with delayed surgical intervention are scarce. The aim of this study was to determine the postoperative results of chronic carpal tunnel syndrome treatment in patients with symptoms lasting for at least 5 years. Materials and Methods: A total of 86 patients (69 females, 17 males) with a mean age of 58 years reporting symptoms of CTS for at least 5 years (mean: 8.5 years) were prospectively studied. The average follow-up time was 33 months. All patients underwent the surgical open decompression of the median nerve at the wrist. A preoperative observation was composed of an interview and a clinical examination. The subjects completed the DASH (the Disabilities of the Arm, Shoulder, and Hand), PRWE (Patient-Rated Wrist Evaluation), and self-report questionnaires. Global grip strength, sensory discrimination, characteristic symptoms of CTS, and thenar muscle atrophy were examined. Postoperatively, clinical and functional examinations were repeated, and patients expressed their opinions by completing a BCTQ (Boston Carpal Tunnel Syndrome Questionnaire). Results: We found improvements in daily activities and hand function postoperatively. Overall, 88% of patients were satisfied with the outcome of surgery. DASH scores decreased after surgery from 44.82 to 14.12 at p < 0.001. PRWE questionnaire scores decreased from 53.34 to 15.19 at p < 0.001. The mean score of the BCTQ on the scale regarding the severity of symptoms was 1.48 and 1.62 on the scale regarding function after surgery. No significant differences were found in the scores between the male and female groups or between age groups (p > 0.05). A significant increase in global grip strength from 16.61 kg to 21.91 kg was observed postoperatively at p < 0.001. No significant difference was detected in the measurement of sensory discrimination (6.02 vs. 5.44). In most of the examined patients, night numbness and wrist pain subsided after surgery at p < 0.001. Thenar muscle atrophy diminished after surgery at p < 0.001. Conclusions: Most patients were satisfied with the results of CTS surgery regarding the open decompression of the median nerve even after 5 years of ineffective conservative treatment. Significant improvement of the hand function was confirmed in the functional studies.

Effect of the SARS-CoV-2 pandemic on planned and emergency hernia repair in Sweden: a register-based study.

PURPOSE: The COVID-19 has had a profound impact on the health care delivery in Sweden, including deprioritization of benign surgeries during the COVID-19 pandemic. The aim of this study was to assess the effect of COVID-19 pandemic on emergency and planned hernia repair in Sweden. METHODS: Data on hernia repairs from January 2016 to December 2021 were retrieved from the Swedish Patient Register using procedural codes. Two groups were formed: COVID-19 group (January 2020-December 2021) and control group (January 2016-December 2019). Demographic data on mean age, gender, and type of hernia were collected. RESULTS: This study showed a weak negative correlation between the number of elective hernia repairs performed each month during the pandemic and the number of emergency repairs carried out during the following 3 months for inguinal hernia repair (p = 0.114) and incisional hernia repair (p = 0.193), whereas there was no correlation for femoral or umbilical hernia repairs. CONCLUSION: The COVID-19 pandemic had a great impact on planned hernia surgeries in Sweden, but our hypothesis that postponing planned repairs would increase the risk of emergency events was not supported.

Is There a "Black Friday" for Geriatric Hip Fracture Surgery?

OBJECTIVES: Reports show an increase in the short-term mortality rates of hip fracture patients admitted on weekends. However, there are few studies on whether there is a similar effect in Friday admissions of geriatric hip fracture patients. The aim of this study was to evaluate the effects of Friday admission on mortality and clinical outcomes in elderly patients with hip fractures. METHODS: A retrospective cohort study was performed at a single orthopaedic trauma centre and included all patients who underwent hip fracture surgery between January 2018 and December 2021. Patient characteristics, including age, sex, BMI, fracture type, time of admission, ASA grade, comorbidities, and laboratory examinations, were collected. Data pertaining to surgery and hospitalization were extracted from the electronic medical record system and tabulated. The corresponding follow-up was performed. The Shapiro-Wilk test was applied to evaluate the distributions of all continuous variables for normality. The overall data were analyzed by Student's t test or the Mann-Whitney U test for continuous variables and the chi-square test for categorical variables, as appropriate. Univariate and multivariate analyses were used to further test for the independent influencing factors of prolonged time to surgery. RESULTS: A total of 596 patients were included, and 83 patients (13.9%) were admitted on Friday. There was no evidence supporting that Friday admission had an effect on mortality and outcomes, including length of stay, total hospital costs and postoperative complications. However, the patients admitted on Friday had delayed surgery. Then, patients were regrouped into two groups according to whether surgery was delayed, and 317 patients (53.2%) underwent delayed surgery. The multivariate analysis showed that younger age (p = 0.014), Friday admission (p < 0.001), ASA classification III-IV (p = 0.019), femoral neck fracture (p = 0.002), time from injury to admission more than 24 h (p = 0.025), and diabetes (p = 0.023) were risk factors for delayed surgery. CONCLUSIONS: Mortality and adverse outcome rates for elderly hip fracture patients admitted on Friday were similar to those admitted at other time periods. However, Friday admission was identified as one of the risk factors for delayed surgery.

Downsizing of rectal cancer following neoadjuvant radiotherapy (5 × 5 Gy) and long interval surgery evaluated using MRI semiautomated volumetric measurements, a retrospective study.

Introduction: Neoadjuvant conventional chemoradiation (CRT) is the standard treatment for primary locally non-curatively resectable rectal cancer, as tumor downsizing may allow R0 resectability. Short-term neoadjuvant radiotherapy (5x5 Gy) followed by an interval before surgery (SRT- delay) is an alternative for multimorbid patients who cannot tolerate CRT. This study examined the extent of tumor downsizing achieved with the SRT-delay approach in a limited cohort that underwent complete re-staging before surgery. Methods: Between March 2018 and July 2021, 26 patients with locally advanced primary adenocarcinoma (>uT3 or/and N+) of the rectum were treated with SRT-delay. 22 patients underwent initial staging and complete re-staging (CT, endoscopy, MRI). Tumor downsizing was assessed by staging and re-staging data and pathologic findings. Semiautomated measurement of tumor volume was performed using mint Lesion™ 1.8 software to evaluate tumor regression. Results: The mean tumor diameter determined on sagittal T2 MRI images decreased significantly from 54.1 (23-78) mm at initial staging to 37.9 (18-65) mm at re-staging before surgery (p <0.001) and to 25.5 (7-58) mm at pathologic examination (p <0.001). This corresponds to a mean reduction in tumor diameter of 28.9 (4.3-60.7) % at re-staging and 51.1 (8.7-86.5) % at pathology. Mean tumor volume determined from transverse T2 MR images mint LesionTM 1.8 software significantly decreased from 27.5 (9.8 - 89.6) cm3 at initial staging to 13.1 (3.7 - 32.8) cm3 at re-staging (p <0.001), corresponding to a mean reduction of 50.8 (21.6 - 77) %. The frequency of positive circumferential resection margin (CRM) (less than 1mm) decreased from 45,5 % (10 patients) at initial staging to 18,2 % (4 patients) at re-staging. On pathologic examination, the CRM was negative in all cases. However, multivisceral resection for T4 tumors was required in 2 patients (9%). Tumor downstaging was noted in 15 of 22 patients after SRT-delay. Conclusion: In conclusion, the observed extent of downsizing is broadly comparable to the results of CRT, making SRT-delay a serious alternative for patients who cannot tolerate chemotherapy.

Delayed Surgical Treatment of Displaced Intra-Articular Calcaneal Fractures in Major Trauma Is Safe and Effective.

BACKGROUND: To assess whether delaying operative fixation through the sinus tarsi approach resulted in a decreased wound complications rate or could hinder the quality of reduction in subjects with Sanders type II and III displaced intra-articular calcaneus fractures. METHODS: From January 2015 to December 2019, all polytrauma patients were screened for eligibility. We divided patients into two groups: Group A, treated within 21 days after injury; Group B, treated more than 21 days after injury. Wound infections were recorded. Radiographic assessment consisted of serial radiographs and CT scans: postoperatively (T0) and at 12 weeks (T1) and at 12 months after surgery (T2). The quality of reduction of the posterior subtalar joint facet and calcaneal cuboid joint (CCJ) was classified as anatomical and non-anatomical. A post hoc power calculation was performed. RESULTS: A total of 54 subjects were enrolled. Four wound complications (three superficial, one deep) were identified in Group A; two wound complications (one superficial one deep) were identified in Group B. According to "mean interval between trauma and surgery" and "duration of intervention", there was a significant difference between the groups (p < 0.001). There were no significant differences between Groups A and B in terms of wound complications or quality of reduction. CONCLUSIONS: The sinus tarsi approach is a valuable approach for the surgical treatment of closed displaced intra-articular calcaneus fractures in major trauma patients who need delayed surgery. The timing of surgery did not negatively influence the quality of the reduction and the wound complication rate. LEVEL OF EVIDENCE: level II, prospective comparative study.

Early versus delayed surgery following neoadjuvant chemoradiation for esophageal cancer: a systematic review and meta-analysis.

BACKGROUND: Neoadjuvant chemoradiotherapy (nCRT) followed by surgery, is the mainstay of managing locally advanced esophageal cancer. However, the optimal timing of surgery after neoadjuvant therapy is not defined clearly. METHODS: A systematic search of PubMed, Embase and Cochrane databases was conducted. 6-8 weeks were used as a cut-off to define early and delayed surgery groups. Overall Survival (OS) was the primary outcome, whereas pathological complete resolution (pCR), R0 resection, anastomotic leak, perioperative mortality, pulmonary complications, and major complication (> Clavien-Dindo grade 2) rates were secondary outcomes. Cohort studies and national registry bases studies were analysed separately. Survival data were pooled as Hazard Ratio (HR) and the rest as Odds Ratio (OR). According to heterogeneity, fixed-effect or random-effect models were used. RESULTS: Twelve retrospective studies, one RCT, and six registry-based studies (13,600 participants) were included. Pooled analysis of cohort studies showed no difference in OS (HR 1.03, CI 0.91-1.16), pCR (OR 0.98, CI 0.80-1.20), R0 resection (OR 0.90, CI 0.55-I.45), mortality (OR 1.03, CI 0.59-1.77), pulmonary complications (OR 1.26, CI 0.97-1.64) or major complication rates (OR 1.29, CI 0.96-1.73). Delayed surgery led to increased leak (OR 1.48, CI 1.11-1.97). Analysis of registry studies showed that the delayed group had a better pCR rate (OR 1.12, CI 1.01-1.24), with no improvement in survival (HR 1.01, CI 0.92-1.10). Delayed surgery was associated with increased mortality (OR 1.35, CI 1.07-1.69) and major complication rate (OR 1.55, CI 1.20-2.01). Available RCT reported surgical outcomes only. CONCLUSION: National registry-based studies' analysis shows that delay in surgery is riskier and leads to higher mortality and major complication rates. Further, well-designed RCTs are required.

Early versus delayed treatment of lateral condylar fracture of the humerus with > 2 mm displacement in children: a retrospective study.

BACKGROUND: The purpose of this study was to investigate the clinical and functional outcomes of early versus delayed treatment of pediatric lateral condylar fractures of the humerus with a displacement greater than 2 mm. METHODS: Sixty-seven children treated surgically at our hospital from March 2016 to September 2021 for lateral condylar fracture of the humerus with displacement > 2 mm were retrospectively analyzed. The children were divided into two groups where early surgery consisted of patients being operated on within 24-h post-injury (n = 36) and delayed surgery consisted of children operated after 24-h post-injury (n = 31). Clinical and functional results were compared between the two groups. RESULTS: There were no significant differences between the two groups in terms of operation time, blood loss and incidences of perioperative complications. However, mean length of incision was significantly greater (P < 0.0001) in the delayed treatment group (5.68 ± 1.08 cm) compared to the early treatment group (3.89 ± 0.82 cm). No differences were found in functional outcomes, consisting of the Baumann angle of the affected limb, the carrying angle, Mayo Elbow Performance Score, and Flynn's criteria at final follow-up. CONCLUSIONS: Delay in surgery for more than 24 h after injury does not influence the clinical and functional results for lateral condylar fracture of the humerus with displacement > 2 mm in children. However, delayed open reduction and pinning may increase the incision length possibly due to increased edema.
