Super-elderly, spinal surgery, evaluating the risks and benefits: a retrospective single-centre cohort study.

INTRODUCTION: An increasingly ageing population presents emerging healthcare challenges. Adequate clinical evaluation and understanding of outcome-predicting factors are integral to delivering safe spinal surgery to super-elderly patients. AIM: To evaluate spine surgery outcomes in patients aged 80 or above. METHODS: We retrospectively evaluated patients 80 years and above who underwent elective or emergency spinal surgery between 2017 and 2022. The Eurospine Surgery Classification (ESC) was used to classify operations into Large, Medium, and Small. We calculated and compared Clinical Frailty Scores (CFS) pre- and post-operatively. RESULTS: Two hundred forty-five patients met the inclusion criteria. Most were male (n = 145). The age range was 80 to 99 (mean 83.3). Most operations were elective (n = 151, 62%). In our cohort, 211, 22, 10,2 and 1 patients had degenerative, trauma, tumour, infective and vascular pathologies, respectively. According to the Eurospine classification, 201 (82.0%) had Minor spine surgery (63 emergently and 138 electively), 38 had Medium surgery (15.5% - 30 emergently and 8 electively), and 6 had Large surgery (2.4% - 1 emergently and 5 electively). 163 (66.5%) were discharged or under follow-up. There were 11 in-patient mortalities (4.5%). Outpatient mortality was 51 (20.8%), with the median time from surgery to death being 504.5 days, all the outpatient mortalities were neither non-spinal pathology nor spinal surgical related. CFS improved across the cohort, from 5 pre-operatively to 4 post-operatively (p < 0.001). CONCLUSION: Spine surgery in those over the 80s can be performed safely and improve their quality of life, as demonstrated by improvements in the CFS. Good patient selection and adequate pre-operative workup is essential, although it may not be possible in emergencies.

Improved rates of postoperative ischemia, completeness of aneurysm occlusion and neurological deficits in elective clipping of anterior circulation aneurysms over the past 20 years - association with technical improvements.

BACKGROUND/PURPOSE: Several periprocedural adjuncts for elective surgical aneurysm treatment have been introduced over the last 20 years to increase safety and efficacy. Besides the introduction of IONM in the late-1990s, ICG-videoangiography (ICG-VAG) since the mid-2000s and intraoperative CT-angiography/-perfusion (iCT-A/-P) since the mid-2010s are available. We aimed to clarify whether the introduction of ICG-VAG and iCT-A/-P resulted in our department in a stepwise improvement in the rate of radiologically detected postoperative ischemia, complete aneurysm occlusion and postoperative new deficits. METHODS: Patients undergoing microsurgical clip occlusion for unruptured anterior circulation aneurysms between 2000 and 2019 were included, with ICG-VAG since 2009 and iCT-A/-P (for selected cases) since 2016. Baseline characteristics and treatment-related morbidity/outcome focusing on differences between the three distinct cohorts (cohort-I: pre-ICG-VAG-era, cohort-II: ICG-VAG-era, cohort-III: ICG-VAG&iCT-A/-P-era) were analyzed. RESULTS: 1391 patients were enrolled (n = 74 were excluded), 779 patients were interventionally treated, 538 patients were surgically clipped by a specialized vascular team (cohort-I n = 167, cohort-II n = 284, cohort-III n = 87). Aneurysm size was larger in cohort-I (8.9 vs. 7.5/6.8 mm; p < 0.01) without differences concerning age (mean:55years), gender distribution (m: f = 1:2.6) and aneurysm location (MCA:61%, ICA:18%, ACA/AcomA:21%). There was a stepwise improvement in the rate of radiologically detected postoperative ischemia (16.2vs.12.0vs.8.0%; p = 0.161), complete aneurysm occlusion (68.3vs.83.6vs.91.0%; p < 0.01) and postoperative new deficits (10.8vs.7.7vs.5.7%; p = 0.335) from cohort-I to -III. After a mean follow-up of 12months, a median modified Rankin scale of 0 was achieved in all cohorts. DISCUSSION: Associated with periprocedural technical achievements, surgical outcome in elective anterior circulation aneurysm surgery has improved in our service during the past 20 years.

Prognostic impact of elective tracheotomy in resected oral cavity squamous cell carcinoma: A nationwide cohort study.

BACKGROUND: Elective tracheotomy is commonly performed in resected oral squamous cell carcinoma (OCSCC) to maintain airway patency. However, the indications for this procedure vary among surgeons. This nationwide study evaluated the impact of tracheotomy on both the duration of in-hospital stay and long-term survival outcomes in patients with OCSCC. METHODS: A total of 18,416 patients with OCSCC were included in the analysis, comprising 7981 patients who underwent elective tracheotomy and 10,435 who did not. The primary outcomes assessed were 5-year disease-specific survival (DSS) and overall survival (OS). To minimize potential confounding factors, a propensity score (PS)-matched analysis was performed on 4301 patients from each group. The duration of hospital stay was not included as a variable in the PS-matched analysis. RESULTS: Prior to PS matching, patients with tracheotomy had significantly lower 5-year DSS and OS rates compared to those without (71% vs. 82%, p < 0.0001; 62% vs. 75%, p < 0.0001, respectively). Multivariable analysis identified tracheotomy as an independent adverse prognostic factor for 5-year DSS (hazard ratio = 1.10 [1.03-1.18], p = 0.0063) and OS (hazard ratio = 1.10 [1.04-1.17], p = 0.0015). In the PS-matched cohort, the 5-year DSS was 75% for patients with tracheotomy and 76% for those without (p = 0.1488). Five-year OS rates were 66% and 67%, respectively (p = 0.0808). Prior to PS matching, patients with tracheotomy had a significantly longer mean hospital stay compared to those without (23.37 ± 10.56 days vs. 14.19 ± 8.34 days; p < 0.0001). Following PS matching, the difference in hospital stay duration between the two groups remained significant (22.34 ± 10.25 days vs. 17.59 ± 9.54 days; p < 0.0001). CONCLUSIONS: While elective tracheotomy in resected OCSCC patients may not significantly affect survival, it could be associated with prolonged hospital stays.

Clinical prediction model for red cell blood transfusion in elective primary posterior lumbar spine fusion.

Overestimated the cross-match of preoperative PRC preparation for elective primary lumbar spinal fusion needs revision for cost-effectiveness. We aimed to develop a novel preoperative predictive model for appropriate PRC preparation. This clinical prediction model in a retrospective cohort was studied between January 2015 and September 2022. Multivariate logistic regression models were used to assess predictive variables. The logistic coefficient of each predictor generated scores to establish a predictive model. The area under the receiver operating characteristic curve (AuROC) was used to evaluate the model. The predictive performance was validated using bootstrapping techniques and externally validated in 102 independent cases. Among 416 patients, 178 (43%) required transfusion. Four final predictors: preoperative hematocrit level, laminectomy level, transforaminal lumbar interbody fusion level, and sacral fusion. When categorized into two risk groups, the positive predictive values for the low-risk score (≤ 4) were 18.4 (95% Cl 13.9, 23.6) and 83.9 (95% CI 77.1, 89.3) for the high-risk score (> 4). AuROC was 0.90. Internal validation (bootstrap shrinkage = 0.993) and external validation (AuROC: 0.91). A new model demonstrated exemplary performance and discrimination in predicting the appropriate preparation for PRC. This study should be corroborated by rigorous external validation in other hospitals and by prospective assessments.

A retrospective cohort study of intra-corporeal versus extra-corporeal anastomosis for right hemicolectomy with cost-effectiveness analysis.

BACKGROUND: We aimed to compare outcomes and cost effectiveness of extra-corporeal anastomosis (ECA) versus intra-corporeal anastomosis (ICA) for laparoscopic right hemicolectomy using the National Surgical Quality Improvement Programme data. METHODS: Patients who underwent elective laparoscopic right hemicolectomy for colon cancer from January 2018 to December 2022 were identified. Non-cancer diagnoses, emergency procedures or synchronous resection of other organs were excluded. Surgical characteristics, peri-operative outcomes, long-term survival and hospitalisation costs were compared. Incremental cost-effectiveness ratio (ICER) was used to evaluate cost-effectiveness. RESULTS: A total of 223 patients (175 ECA, 48 ICA) were included in the analysis. Both cohorts exhibited comparable baseline patient, comorbidity, and tumour characteristics. Distribution of pathological TMN stage, tumour largest dimension, total lymph node harvest and resection margin lengths were statistically similar. ICA was associated with a longer median operative duration compared with ECA (255 min vs. 220 min, P < 0.001). There was a quicker time to gastrointestinal recovery, with a shorter median hospital stay in the ICA group (4.0 versus 5.0 days, P = 0.001). Overall complication rates were comparable. ICA was associated with a higher surgical procedure cost (£6301.57 versus £4998.52, P < 0.001), but lower costs for ward accommodation (£1679.05 versus £2420.15, P = 0.001) and treatment (£3774.55 versus £4895.14, P = 0.009), with a 4.5% reduced overall cost compared with ECA. The ICER of -£3323.58 showed ICA to be more cost effective than ECA, across a range of willingness-to-pay thresholds. CONCLUSION: ICA in laparoscopic right hemicolectomy is associated with quicker post-operative recovery and may be more cost effective compared with ECA, despite increased operative costs.

Intermittend pneumatic venous thrombembolism (VTE) prophylaxis during neurosurgical procedures.

BACKGROUND: The management of perioperative venous thrombembolism (VTE) prophylaxis is highly variable between neurosurgical departments and general guidelines are missing. The main issue in debate are the dose and initiation time of pharmacologic VTE prevention to balance the risk of VTE-based morbidity and potentially life-threatening bleeding. Mechanical VTE prophylaxis with intermittend pneumatic compression (IPC), however, is established in only a few neurosurgical hospitals, and its efficacy has not yet been demonstrated. The objective of the present study was to analyze the risk of VTE before and after the implementation of IPC devices during elective neurosurgical procedures. METHODS: All elective surgeries performed at our neurosurgical department between 01/2018-08/2022 were investigated regarding the occurrence of VTE. The VTE risk and associated mortality were compared between groups: (1) only chemoprophylaxis (CHEMO; surgeries 01/2018-04/2020) and (2) IPC and chemoprophylaxis (IPC; surgeries 04/2020-08/2022). Furthermore, general patient and disease characteristics as well as duration of hospitalization were evaluated and compared to the VTE risk. RESULTS: VTE occurred after 38 elective procedures among > 12.000 surgeries. The number of VTEs significantly differed between groups with an incidence of 31/6663 (0.47%) in the CHEMO group and 7/6688 (0.1%) events in the IPC group. In both groups, patients with malignant brain tumors represented the largest proportion of patients, while VTEs in benign tumors occurred only in the CHEMO group. CONCLUSION: The use of combined mechanical and pharmacologic VTE prophylaxis can significantly reduce the risk of postoperative thromboembolism after neurosurgical procedures and, therefore, reduce mortality and morbidity.

Relationship between preoperative nutritional status assessed using anthropometric measures and postoperative complications in pediatric surgical patients.

AIM: To determine the relationship between preoperative nutritional status assessed using anthropometric measures and postoperative complications in pediatric surgical patients. METHODOLOGY: This prospective observational cohort study included 650 patients from 6 months to 18 years undergoing elective surgery at our institution. Elective surgery included procedures such as herniotomy, orchidopexy, urethroplasty, cystoscopy, PUV fulguration, pyeloplasty, ureteric reimplantation, stoma formation/closure, anorectoplasty, pull-through, choledochal cyst excision and repair, VP shunt insertion, lipomyelomeningocele repair, diastematomyelia excision and repair, and cyst excision. Nutritional status was standardized using Z scores for weight, length, and BMI. Patients were monitored for a month following surgery to detect any complications, and they were classified into five grades using the Clavien-Dindo classification. The duration of hospital stays and readmission within 30 days following discharge were secondary outcomes. RESULTS: There were 627 patients of both sexes involved in the study: 350 patients aged 6 months to 5 years (Group A), while 277 were aged between 5 and 18 years (Group B). Wasting status was 47.71% in Group A and 41.52% in Group B. In Group A, 40% of patients were stunted, while 83.75% were in Group B. Group A had 57.14% underweight patients. The complication rate was 39.14% in Group A and 38.99% in Group B. The incidence of postoperative complications was not significantly different in malnourished patients. The patients with prolonged duration of surgery (> 2 h) developed more complications in both groups (Group A-67.2%, Group B-82.6%; p < 0.0001). In addition, the patients who experienced complications had lengthier hospital stays (p < 0.001 in both groups) and increased readmission rates (p = 0.016 in Group A and p = 0.008 in Group B). CONCLUSION: In our study, half of the patients in Group A and nearly two-third in Group B were malnourished. The preoperative poor nutritional status based on anthropometric parameters is not associated with increased postoperative complications. Randomized control trials linking preoperative malnutrition based on anthropometric measures and clinical outcomes in pediatric surgery patients are necessary to provide more robust information on this subject.

Delayed elective total shoulder arthroplasty: causes and eventual outcomes.

PURPOSE: The purpose of this study is to identify risk factors for delays in planned total shoulder arthroplasty (TSA) and determine the perioperative outcomes of TSAs that experienced a delay. METHODS: The American College of Surgeons National Quality Improvement Program (NSQIP) database was queried from 2006 to 2019 for primary TSA. Delayed TSA was defined as surgery that occurred greater than one day after hospital admission. Patient demographics, comorbidities, and post-operative complications were collected and compared; the incidence of delayed TSA was analyzed. RESULTS: The delayed patients were older, had a higher BMI, a higher rate of recent prior major surgery, and more comorbidities. Delayed patients had higher rates of postoperative complications, return to the OR, and 30-day readmission. Between 2006 and 2019, the rate of delayed TSA decreased. CONCLUSION: Surgeons should take care to ensure that patients with comorbidities undergo thorough preoperative clearance to prevent same-day cancellations and postoperative complications.

PreScheck Team Study: prehabilitation clinic as an effective patient management tool in elective cardiac surgery.

INTRODUCTION: The main purpose of the study was to assess the impact of preoperative interdisciplinary assessment by the PreScheck Team on optimization of the final selection for elective cardiac surgery. MATERIAL AND METHODS: This is a single-centre prospective observational study. The examined population consisted of 933 adult patients planned for cardiac surgery. After the exclusion of urgent operations, the study group consisted of 288 patients planned for elective cardiac surgery within 3 months from 1.01.2023 with PreScheck assessment (PreScheck Team group 2) and a control group of 311 patients scheduled for elective cardiac surgery between 1.03.2022 and 30.06.2022 (4 months), without preoperative interdiscipli-nary assessment (No PreScheck Team group 2). RESULTS: Fifty-two patients (18.06%) from the study group were finally excluded from the surgery on the scheduled date. In 46 patients (88.46%) the temporary or permanent exclusion from surgery was a result of PreScheck Team assessment. In the control group 42 patients (13.5%) did not undergo surgery on the scheduled date. Twenty-seven of those patients (8.97%) were permanently excluded from cardiac surgery after admission to the hospital and required additional tests before the final clinical decision, with total hospitalization time of 146 days. CONCLUSIONS: Pre Surgery Check (PreScheck) Team is an original concept that combines classical preoperative assessment and an outpatient prehabilitation clinic. The approach we are proposing here should be a complementary stage in the process of selection for elective cardiac surgery, in addition to the Heart Team recommendation. This two-step decision-making enables real individual risk assessment, selection of the most suitable intervention and better use of medical resources.

Effect of Weighted Blanket Versus Traditional Practices on Anxiety and Pain in Patients Undergoing Elective Surgery: A Multicenter Randomized Controlled Trial.

Perioperative anxiety is common in surgical patients and linked to poor outcomes. This multicenter randomized controlled trial assessed the effect of the use of a warm weighted blanket on presurgical anxiety and pain, as well as postsurgical restlessness, nausea, and vomiting. Levels of anxiety and pain were measured in adult patients using a 100-point visual analog scale before elective surgery. Patients received either a warm weighted blanket (n = 74) or a traditional sheet or nonweighted blanket (n = 74). Patients in the intervention group had significantly lower preoperative anxiety scores (mean [SD] = 26.28 [25.75]) compared to the control group (mean [SD] = 38.73 [30.55], P = .008). However, the intervention had no significant effect on presurgical pain or postsurgical nausea, vomiting, or restlessness. These results suggest that weighted blankets reduce preoperative anxiety in adult patients.

Superiority trial for the development of an ideal method for the closure of midline abdominal wall incisions to reduce the incidence of wound complications after elective gastroenterological surgery: study protocol for a randomized controlled trial.

BACKGROUND: The recent guidelines from the European and American Hernia Societies recommend a continuous small-bite suturing technique with slowly absorbable sutures for fascial closure of midline abdominal wall incisions to reduce the incidence of wound complications, especially for incisional hernia. However, this is based on low-certainty evidence. We could not find any recommendations for skin closure. The wound closure technique is an important determinant of the risk of wound complications, and a comprehensive approach to prevent wound complications should be developed. METHODS: We propose a single-institute, prospective, randomized, blinded-endpoint trial to assess the superiority of the combination of continuous suturing of the fascia without peritoneal closure and continuous suturing of the subcuticular tissue (study group) over that of interrupted suturing of the fascia together with the peritoneum and interrupted suturing of the subcuticular tissue (control group) for reducing the incidence of midline abdominal wall incision wound complications after elective gastroenterological surgery with a clean-contaminated wound. Permuted-block randomization with an allocation ratio of 1:1 and blocking will be used. We hypothesize that the study group will show a 50% reduction in the incidence of wound complications. The target number of cases is set at 284. The primary outcome is the incidence of wound complications, including incisional surgical site infection, hemorrhage, seroma, wound dehiscence within 30 days after surgery, and incisional hernia at approximately 1 year after surgery. DISCUSSION: This trial will provide initial evidence on the ideal combination of fascial and skin closure for midline abdominal wall incision to reduce the incidence of overall postoperative wound complications after gastroenterological surgery with a clean-contaminated wound. This trial is expected to generate high-quality evidence that supports the current guidelines for the closure of abdominal wall incisions from the European and American Hernia Societies and to contribute to their next updates.

Barbed versus conventional suture in elective posterior spine surgery.

PURPOSE: Barbed sutures are tissue control devices that can reduce operating room time and costs. We analyzed the utility of barbed sutures in posterior spinal surgery in order to prove non-inferiority to conventional methods for wound closure. METHODS: A cohort of patients undergoing elective posterior spinal surgery in which barbed (prospective) versus conventional sutures (retrospective) were used was analyzed. The primary endpoint was the occurrence of wound healing complications or the need for surgical revision. Secondary endpoints included postoperative stay, readmission rate, and duration and cost of wound closure. RESULT: A total of 483 patients participated in the study, 183 in the Barbed group and 300 in the Conventional group. Wound dehiscence or seroma occurred in 3.8% and 2.7% of the Barbed and Conventional groups, respectively (p = 0.6588). Both superficial (1.6% versus 4.0%, P = 0.2378) and deep infections (2.7% versus 4.7%, p = 0.4124) occurred similarly in both groups. Overall, the rate of re-intervention due to wound healing problems was also similar (4.9% versus 5.3%, p = 0.9906), as well as, total median hospital stay, postoperative stay and 30-day re-admission rates. The average duration of wound closure (1.66 versus 4.16 min per level operated, p < 0.0001) strongly favored the Barbed group. The mean cost of wound closure per patient was higher in the Barbed group (43.23 € versus 22.67 €, p < 0.0001). CONCLUSIONS: In elective posterior spinal procedures, the use of barbed sutures significantly reduced the duration of wound closure. The wound healing process was not hindered and the added cost related to the suture material was small.

Evolution of enhanced recovery for children undergoing elective intestinal surgery.

Enhanced recovery protocols (ERP) have been widely adopted in adult populations, with over 30 years of experience demonstrating the effectiveness of these protocols in patients undergoing gastrointestinal (GI) surgery. In the last decade, ERPs have been applied to pediatric populations across multiple subspecialties. The objective of this manuscript is to explore the evolution of how ERPs have been implemented and adapted specifically for pediatric populations undergoing GI surgery, predominantly for inflammatory bowel disease. The reported findings reflect a thorough exploration of the literature, including initial surveys of practice/readiness assessments, consensus recommendations of expert panels, and data from a rapidly growing number of single center studies. These efforts have culminated in a national prospective, multicenter trial evaluating clinical and implementation outcomes for enhanced recovery in children undergoing GI surgery. In short, this historical and clinical review reflects on the evolution of ERPs in pediatric surgery and expounds upon the next steps needed to apply ERPs to future pediatric populations.

The Effect of Dexmedetomidine as a Local Anesthetic Adjuvant for Iliac Fascia Compartment Block on Postoperative Delirium in Elderly Patients Undergoing Elective Hip Surgery.

INTRODUCTION: We analyzed the effect of dexmedetomidine (DEX) as a local anesthetic adjuvant on postoperative delirium (POD) in elderly patients undergoing elective hip surgery. METHODS: In this study, 120 patients undergoing hip surgery were enrolled and randomly assigned to two groups: fascia iliaca compartment block with DEX + ropivacaine (the Y group, n = 60) and fascia iliaca compartment block with ropivacaine (the R group, n = 60). The primary outcomes: presence of delirium during the postanesthesia care unit (PACU) period and on the first day (D1), the second day (D2), and the third day (D3) after surgery. The secondary outcomes: preoperative and postoperative C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), occurrence of insomnia on the preoperative day, day of operation, D1 and D2; HR values of patients in both groups before iliac fascia block (T1), 30 min after iliac fascia block (T2), at surgical incision (T3), 20 min after incision (T4), when they were transferred out of the operating room (T5) and after leaving the recovery room (T6) at each time point; VAS for T1, PACU, D1, D2; the number of patients requiring remedial analgesics within 24 h after blockade and related complications between the two groups. RESULTS: A total of 97 patients were included in the final analysis, with 11 and 12 patients withdrawing from the R and Y groups, respectively. The overall incidence of POD and its incidence in the PACU and ward were all lesser in the Y group than in the R group (p < 0.05). Additionally, fewer cases required remedial analgesia during the PACU period, and more vasoactive drugs were used for maintaining circulatory system stability in the Y group as compared to the R group (p < 0.05). At the same time, the incidence of intraoperative and postoperative bradycardia in the Y group was higher than that in the R group, accompanied by lower postoperative CRP and ESR (all p < 0.05). CONCLUSION: Ultrasound-guided high fascia iliaca compartment block with a combination of ropivacaine and DEX can reduce the incidence of POD, the use of intraoperative opioids and postoperative remedial analgesics, and postoperative inflammation in elderly patients who have undergone hip surgery, indicating that this method could be beneficial in the prevention and treatment of POD.

The impact of elective surgery postponement during COVID-19 on emergency bellwether procedures in a large tertiary centre in Singapore.

The coronavirus disease 2019 (COVID-19) pandemic drove many healthcare systems worldwide to postpone elective surgery to increase healthcare capacity, manpower, and reduce infection risk to staff. The aim of this study was to assess the impact of an elective surgery postponement policy in response to the COVID-19 pandemic on surgical volumes and patient outcomes for three emergency bellwether procedures. A retrospective cohort study of patients who underwent any of the three emergency procedures [Caesarean section (CS), emergency laparotomy (EL), and open fracture (OF) fixation] between 1 January 2018 and 31 December 2021 was conducted using clinical and surgical data from electronic medical records. The volumes and outcomes of each surgery were compared across four time periods: pre-COVID (January 2018-January 2020), elective postponement (February-May 2020), recovery (June-November 2020), and postrecovery (December 2020-December 2021) using Kruskal-Wallis test and segmented negative binomial regression. There was a total of 3886, 1396, and 299 EL, CS, and OF, respectively. There was no change in weekly volumes of CS and OF fixations across the four time periods. However, the volume of EL increased by 47% [95% confidence interval: 26-71%, P = 9.13 × 10-7) and 52% (95% confidence interval: 25-85%, P = 3.80 × 10-5) in the recovery and postrecovery period, respectively. Outcomes did not worsen throughout the four time periods for all three procedures and some actually improved for EL from elective postponement onwards. Elective surgery postponement in the early COVID-19 pandemic did not affect volumes of emergency CS and OF fixations but led to an increase in volume for EL after the postponement without any worsening of outcomes.

Is mechanical bowel preparation mandatory for elective colon surgery? A systematic review and meta-analysis.

BACKGROUND: Growing evidence demonstrates minimal impact of mechanical bowel preparation (MBP) on reducing postoperative complications following elective colectomy. This study investigated the necessity of MBP prior to elective colonic resection. METHOD: A systematic literature review was conducted across PubMed, Ovid, and the Cochrane Library to identify studies comparing the effects of MBP with no preparation before elective colectomy, up until May 26, 2023. Surgical-related outcomes were compiled and subsequently analyzed. The primary outcomes included the incidence of anastomosis leakage (AL) and surgical site infection (SSI), analyzed using Review Manager Software (v 5.3). RESULTS: The analysis included 14 studies, comprising seven RCTs with 5146 participants. Demographic information was consistent across groups. No significant differences were found between the groups in terms of AL ((P = 0.43, OR = 1.16, 95% CI (0.80, 1.68), I2 = 0%) or SSI (P = 0.47, OR = 1.20, 95% CI (0.73, 1.96), I2 = 0%), nor were there significant differences in other outcomes. Subgroup analysis on oral antibiotic use showed no significant changes in results. However, in cases of right colectomy, the group without preparation showed a significantly lower incidence of SSI (P = 0.01, OR = 0.52, 95% CI (0.31, 0.86), I2 = 1%). No significant differences were found in other subgroup analyses. CONCLUSION: The current evidence robustly indicates that MBP before elective colectomy does not confer significant benefits in reducing postoperative complications. Therefore, it is justified to forego MBP prior to elective colectomy, irrespective of tumor location.

Should Advanced Age Preclude Surgical Treatment of Gastrointestinal Stromal Tumor?

Introduction: Surgical resection is a gold standard treatment for gastrointestinal stromal tumors (GISTs). It can be performed by minimally invasive surgery approach in most of the patients. It has been shown that advanced age is not a clear poor prognostic factor in patients who underwent surgery for GIST. We hypothesized that elderly patients undergo elective surgery less often compared to younger population. We aim to evaluate the safety, efficacy and oncological results of GIST treatment in the elderly population in our Medical Center. Materials and Methods: All patients who underwent surgery for GIST in Shamir Medical Center from January 1, 2016, to July 31, 2023, were included in the study. The patients were divided into 2 groups. Group 1 included patients younger than 75 years, while patients older than 75 years were included in Group 2. The groups were compared according to demographics, clinical and surgical parameters, complications, and pathology results. Results: Overall, 49 patients were included in the study. Group 1 included 28 patients and Group 2 included 21 patients. Group 2 patients more often underwent emergency surgery (52.4% versus 14.3%, P < .05) and had increased open surgery rate (19% versus 0%, P < .05). No difference between the groups was noted in surgical parameters, complications, and length of hospital stay. Tumor size, number of mitoses, level of ki67%, and involvement of surgical margins were not significantly different. However, in Group 2 patients, tumor size was larger and there was a trend toward higher rate of ki67 > 5%. Conclusion: Elderly patients with GIST are less frequently undergoing electively surgery and relatively often undergo open surgery. Frequency of complications is similar in elderly patients compares to younger patients group.

What Role does Marital Status Play in the Outcome of Abdominoplasties? A Single-Surgeon Experience With 712 Cases.

BACKGROUND: Marital status is a commonly reported demographic variable in scientific literature. Numerous reports suggested difference in the medical outcomes of patients when stratified based on marital status. Although many reports suggested that married patient exhibit improved survival when compared to their counterparts, other reports could not replicate similar conclusions. PURPOSE: determine whether marital status plays a role in the postoperative outcomes of elective abdominoplasty patients. METHODS: The medical records of all abdominoplasty patients operated by a single surgeon over the course of 20 years were reviewed. Information regarding the preoperative state of patients, surgical procedure, and postoperative outcomes was evaluated in respect to the patients marital status. RESULTS: Seven-hundred and twelve patients were included in this study, of whom 516 (%) were married. No difference in preoperative characteristics, medical background, surgical procedure or concomitant surgeries was found. Analysis of adverse events did not demonstrate a statistically significant association with marital status. Additionally, when all unwed patients were grouped together, the results did not differ. CONCLUSION: Marital status does not play a critical role in the postoperative outcomes of patients undergoing elective abdominoplasties for cosmetic indications.
