Recent evidence for subcutaneous drains to prevent surgical site infections after abdominal surgery: A systematic review and meta-analysis.

Surgical site infections (SSIs) increase mortality, hospital stays, additional medical treatment, and medical costs. Subcutaneous drains prevent SSIs in gynecological and breast surgeries; however, their clinical impact in abdominal surgery remains unclear. To investigate whether subcutaneous drains were beneficial in abdominal surgery using a systematic review and meta-analysis. The database search used PubMed, MEDLINE, and the Cochrane Library. The following inclusion criteria were set for the systematic review: (1) Randomized controlled trial studies comparing SSIs after abdominal surgery with or without subcutaneous drains; and (2) Studies that described clinical outcomes, such as SSIs, seroma formation, the length of hospital stays, and mortality. Eight studies were included in this meta-analysis. The rate of total SSIs was significantly lower in the drained group (54/771, 7.0%) than in the control group (89/759, 11.7%), particularly in gastrointestinal surgery. Furthermore, the rate of superficial SSIs was slightly lower in the drained group (31/517, 6.0%) than in the control group (49/521, 9.4%). No significant differences were observed in seroma formation between the groups. Hospital stays were shorter in the drained group than in the control group. Subcutaneous drains after abdominal surgery prevented SSIs and reduced hospital stays but did not significantly affect seroma formation. The timing of drain removal needs to be reconsidered in future studies.

Lack of Routine Postoperative Labs Not Associated With Complications in Pediatric Perforated Appendicitis

IntroductionPostoperative (postop) management of pediatric perforated appendicitis varies significantly, and postop intra-abdominal abscesses (IAA) remain a significant issue. Between 2019 and 2020, our standardized protocol included routine postop labs after an appendectomy for perforated appendicitis. However, given the lack of predictive utility of these routine labs, we discontinued this practice in 2021. We hypothesize that discontinuing routine postop labs will not be associated with an increase in complication rates after an appendectomy for pediatric perforated appendicitis. MethodsA single-institution, retrospective review of all pediatric appendectomies for perforated appendicitis from January 2019 to December 2021 was conducted at University Hospitals Rainbow Babies and Children's Hospital in Cleveland, Ohio. Data were collected on rate of complications (IAA development, re-admissions, bowel obstructions, superficial surgical site infections, intensive care unit transfers, Clostridium difficile infections, allergic reactions, and transfusions), postop imaging, postop interventions, and length of stay. Statistical analysis was completed using Fisher's exact test and Mann–Whitney U-test. ResultsA total of 109 patients (2019-2020 n = 61, 2021 n = 48) were included in the study. All 61 patients from 2019 to 2020 had postop labs compared to only eight patients in 2021. There was no statistically significant difference between the two groups in overall complication rates, but there was a decrease in IAAs reported in 2021 (P = 0.03). There were no statistically significant differences in other complications, postop imaging usage, or postop interventions. The median length of stay was 4.5 d in 2021 compared to 6.0 d in 2019-2020 (P = 0.009). ConclusionsDiscontinuing routine postop labs is not associated with an increase in overall complications rates. Further studies are needed to determine whether routine postop labs can be safely removed in pediatric patients with perforated appendicitis, which would reduce patient discomfort and care costs.

A Prospective Randomized Controlled Trial Comparing Clinical Equivalence of PD Synth and PDS Polydioxanone Sutures.

Introduction Incisional hernia is a common complication of midline laparotomy that may develop even after several years of surgery. Abdominal fascia closure with ideal suture material reduces the incidence of incisional hernia. This study compared the clinical equivalence of PD Synth (Healthium Medtech Limited) and PDS(Ethicon, Johnson & Johnson) slowly absorbed polydioxanone suture with respect to the occurrence of incisional hernia, following elective/emergency midline laparotomy. Methods Eighty-eight subjects undergoing elective/emergency midline laparotomy were randomized to PD Synth (n=45) and PDS(n=43) groups of this prospective, multicenter, randomized (1:1), single-blind, two-arm, parallel-group study (December 2020-May 2023). Primary endpoint was incidence of incisional hernia, occurring within six and 12 months of surgery. Secondary endpoints included incidence of fascial dehiscence, surgical site infection (SSI), suture sinus, seroma, hematoma, scar tenderness, and re-suturing, and evaluation of operative data, hospital stay, intra-operative suture handling, pain, time to return to normal day-to-day activities and work, overall patient satisfaction score, and adverse events. Results One subject in both PD Synthand PDSgroups (p>0.05) developed incisional hernia at umbilicus 12 months post-laparotomy. In PDSgroup, one subject each had incidences of SSI on day 2, day 7, and one month, two subjects developed seroma on day seven, and one subject had readmission on one month; two subjects in PD Synthgroup developed superficial SSI (one month). Findings of other secondary endpoints were comparable between the groups. Conclusion Primary and secondary outcomes manifested that PD Synthand PDSslowly absorbed polydioxanone sutures are clinically equivalent, and can be used for abdominal fascial closure following midline laparotomy.

Antimicrobial peptide dendrimers assisted Nanocomposite-Loaded lyotropic liquid crystalline for multimodal surgical site infection management

Superficial incisional surgical site infections (SISSIs) were a serious challenge leading to delayed wound healing and even systemic diseases. The high incidence of antibiotic resistance and unprotected wound lesions severely hindered the current therapeutical efficiency. In this study, an antibacterial nanocomposite PAMAM-PLL@AuNPs was designed to avoid antibiotic resistance, and a lyotropic liquid crystal system was used for local drug delivery and protecting lesions. The PAMAM-PLL was constructed with polyamide amine (PAMAM) as the core and polylysine (PLL) as the branch chain, which increased the antibacterial activity by 4 times. After being connected to gold nanoparticles (AuNPs), a further 2 times antibacterial activity improvement was achieved. PAMAM-PLL@AuNPs could eliminate bacteria by multimodal mechanisms, including causing leakage of intracellular substances, inducing intracellular reactive oxygen species and inhibiting bacterial metabolism. Thanks to their spontaneous phase transition and the mechanical response characteristics of the lattice structure, lyotropic liquid crystal with self-healing characteristics was employed to load PAMAM-PLL@AuNPs. The unique structure facilitated buffering external forces and accelerated wound healing. The excellent antibacterial and wound healing properties of the lyotropic liquid crystal drug delivery system were confirmed by a surgical incision infection model. This study is expected to provide a robust strategy for the treatment of SISSIs.

Surgical site infection following abdominal cancer surgery: a retrospective study in a tertiary care cancer hospital

Background: Surgical site infections (SSIs) are significant complications following abdominal cancer surgery, resulting in patient discomfort, prolonged hospitalization, and increased healthcare costs. Despite efforts to mitigate their occurrence, SSIs remain a challenge in healthcare settings, particularly in low- and middle-income countries. Materials and Methods: This retrospective cross-sectional study aimed to determine the incidence, risk factors, microbiological patterns, and impact of SSIs in patients undergoing open abdominal cancer surgery at a tertiary cancer hospital in Nepal. Results: A total of 206 patients were included in the study, with an SSI incidence of 35.4%. Superficial SSIs accounted for 87.7% of cases, while 12.2% were deep or organ/space infections. The study explored various risk factors, including patient demographics, wound classification, surgical type, and preoperative conditions, and although certain factors showed associations, none reached statistical significance. Notably, longer surgical duration was linked to a higher risk of SSIs. Patients with SSIs experienced significantly longer hospital stays compared to those without SSIs. The predominant pathogens isolated were Escherichia coli, Staphylococcus aureus, and Citrobacter freundii, many of which displayed multidrug resistance. Conclusions: These findings highlight the need for tailored prevention strategies, prudent antibiotic use, and enhanced infection control measures in this high-risk population undergoing abdominal cancer surgery.

Role of Pre-Operative Nutrition Status on Surgical Site Infection After Posterior Lumbar Interbody Fusion: A Retrospective Study.

Background: A retrospective case-control study to determine the role of pre-operative systemic and local nutritional factors on patients developing a surgical site infection (SSI) after posterior lumbar interbody fusion (PLIF). Surgical site infection after PLIF remains a substantial cause of morbidity. The literature demonstrates the prognosis of surgical patients is associated with pre-operative nutritional status that not only includes systemic nutritional factors, such as prognostic nutritional index (PNI), body mass index (BMI), and serum albumin, but also local nutritional factors, such as subcutaneous fat thickness at the surgical site, including absolute fat thickness and relative fat thickness. However, the role of pre-operative nutrition status in SSI after PLIF surgery remains unclear. Patients and Method: A retrospective review was performed on a consecutive cohort of 766 consecutive adult patients who underwent PLIF surgery for lumbar degenerative conditions between 2020 and 2021 at Second Xiangya Hospital. Previously identified risk factors as well as systemic and local nutritional factors nutritional factors were collected. Results: Among the 766 patients, 38 had post-operative SSI including 15 superficial SSI and 23 deep SSI. Univariable analysis showed that body weight, BMI, PNI, serum albumin, and relative fat thickness differed between the SSI and non-SSI groups. Multivariable logistic regression analysis showed that pre-operative PNI and relative fat thickness were independently associated with SSI after PLIF surgery. Conclusions: Lower pre-operative PNI and higher relative fat thickness are independent risk factors for developing deep SSI after PLIF.

Risk Factors Associated with Postoperative Outcomes in Diverticular Disease Undergoing Elective Colectomy—A Retrospective Cohort Study from the ACS-NSQIP Database

Recommendations for elective colectomies after recovery from uncomplicated acute diverticulitis should be individualized. The kinds of associated risk factors that should be considered for this approach remain undetermined. The aim of this study was to identify the risk factors associated with postoperative outcomes in patients with diverticular disease after receiving an elective colectomy. This is a retrospective study using the multi-institutional, nationally validated database of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP). The patients who were diagnosed with diverticular disease and received an elective colectomy were included in our risk factor analyses. Postoperative mortality, morbidity, and overall complications were measured. Univariate and multivariate analyses were used to demonstrate the risk factors. We analyzed 30,468 patients with diverticular disease, 67% of whom received an elective colectomy. The rate of 30-day mortality was 0.2%, and superficial surgical site infection was the most common postoperative morbidity (7.2%) in the elective colectomies. The independent risk factors associated with overall complications were age ≥ 75, BMI ≥ 30, smoking status, dyspnea, hypertension, current kidney dialysis, chronic steroid use, ASA III, and open colectomy. In laparoscopic colectomy, 67.5% of the elective colectomies, the associated risk factors associated with overall complications still included age ≥ 75, smoking, hypertension, chronic steroid use, and ASA III. Identification of patient-specific risk factors may inform the decision-making process for elective colectomy and reduce the postoperative complications after mitigation of those risk factors.

The Impact of Cefepime and Ampicillin/Sulbactam on Preventing Post-Cesarean Surgical Site Infections, Randomized Controlled Trail.

Over the previous three decades, the rate of caesarean sections performed worldwide has grown exponentially. In comparison to a vaginal birth, the risk of all postpartum infections is higher with a cesarean section. One of the key factors contributing to maternal morbidity is the development of infectious complications in the surgical site after a caesarean section. The primary goal of the research was to compare the efficiency of using ampicillin/sulbactam (AMS) and cefepime (CEF) to reduce the incidence of surgical site infections (SSI) following caesarean delivery. This prospective randomized study was conducted among 200 pregnant women scheduled for elective cesarean section. They were collected from the Obstetrics and Gynecology department of Beni-Suef University Hospital, and then they were randomly assigned into two groups. Group (A) received cefepime 30 min before and 12 h after cesarean delivery, while group (B) received ampicillin/sulbactam 30 min before and 12 h after cesarean delivery. The groups were matched regarding the baseline women characteristics. Comparing the cefepime to the ampicillin/sulbactam revealed that the cefepime significantly decreased superficial SSI from 27% to 14% (0.023). A significant decrease was observed in deep SSI with cefepime compared to ampicillin/sulbactam from 24% to 13% (p-value 0.045). Interestingly, when the cefepime was compared to the ampicillin/sulbactam, we noted that the incidence of endometritis significantly decreased from 13% to 5% (p = 0.048). A noted decrease in post-operative fever in cefepime as compared to ampicillin/sulbactam from 18% to 13% (p-value = 0.329). Receiving prophylactic cefepime pre- and post-cesarean delivery significantly decreases post-operative wound infection and endometritis.

Addition of gentamicin for antibiotic prophylaxis in hip hemiarthroplasty does not decrease the rate of surgical site infection.

The addition of Gram-negative coverage to antibiotic prophylaxis protocols prior to elective total hip arthroplasty (THA) has been reported to reduce periprosthetic joint infection (PJI). However, it is unknown whether adding a Gram-negative-targeted antibiotic agent improves outcomes in the trauma population. This study aimed to investigate whether the addition of a single, pre-operative dose of Gentamicin is associated with lower rates of PJI in patients undergoing hemiarthroplasty (HA) as treatment for a hip fracture. We retrospectively reviewed cases of patients who underwent HA as treatment for a hip fracture from January 2011 to January 2022, and had a minimum 1-year of follow-up. Patients were divided into two groups based on the antibiotic prophylaxis they received during surgery: cefazolin (control group) or cefazolin with addition of Gentamicin (case group). The primary outcome was the rate of surgical site infections (SSI), and secondary outcomes included rates of prosthetic joint infection (PJI) and superficial SSIs. The final study population consisted of 1521 patients. 336 patients (22.1%) were in the case group and 1185 (77.9%) patients were in the control group. Rates of SSI were comparable between the groups (3.8% for the case group vs. 2.8% in the control group, p = 0.34). This held true for both PJIs (3.5 vs. 2.5%, p = 0.3) and superficial SSIs (0.29 vs. 0.33%, p = 0.91). The distribution of the causing pathogen was similar between the groups (p = 0.84). Gentamicin susceptibility rates of the Gram-negative bacteria associated with PJI were similar between the cohorts (p = 0.51). The addition of a single, pre-operative dose of Gentamicin to the antibiotic prophylaxis protocol of patients undergoing HA as treatment for a hip fracture was not associated with lower rates of SSI, PJI or superficial SSI. The findings of this study indicate that the prophylactic benefits of Gentamicin may not apply to HA as they do to THA.

Fifteen Years of Spinal Fusion Outcomes in Children With Cerebral Palsy: Are We Getting Better?

Retrospective multicenter study. We reviewed 15-year trends in operative factors, radiographic and quality of life outcomes, and complication rates in children with cerebral palsy (CP)-related scoliosis who underwent spinal fusion. Over the past two decades, significant efforts have been made to decrease complications and improve outcomes of this population. We retrospectively reviewed a multicenter registry of pediatric CP patients who underwent spinal fusion from 2008 to 2020. We evaluated baseline and operative, hospitalization, and complication data as well as radiographic and quality of life outcomes at a minimum 2-year follow-up. Mean estimated blood loss and transfusion volume declined from 2.7±2.0L in 2008 to 0.71±0.34L in 2020 and 1.0±0.5L in 2008 to 0.5±0.2L in 2020, respectively, with a concomitant increase in antifibrinolytic use from 58% to 97% (all, P <0.01). Unit rod and pelvic fusion use declined from 33% in 2008 to 0% in 2020 and 96% in 2008 to 79% in 2020, respectively (both, P <0.05). Mean postoperative intubation time declined from 2.5±2.6 to 0.42±0.63 days ( P< 0.01). No changes were observed in preoperative and postoperative coronal angle and pelvic obliquity, operative time, frequency of anterior/anterior-posterior approach, and durations of hospital and intensive care unit stays. Improvements in the Caregiver Priorities and Child Health Index of Life with Disabilities postoperatively did not change significantly over the study period. Complication rates, including reoperation, superficial and deep surgical site infection, and gastrointestinal and medical complications remained stable over the study period. Over the past 15 years of CP scoliosis surgery, surgical blood loss, transfusion volumes, duration of postoperative intubation, and pelvic fusion rates have decreased. However, the degree of radiographic correction, the rates of surgical and medical complications (including infection), and health-related quality of life measures have broadly remained constant.

Preferring Lateral Video Endoscopic Inguinal Lymph Node Dissection Over Classic Video Endoscopic Inguinal Lymph Node Dissection in Squamous Cell Carcinoma of Penis: Lessons Learnt from Twenty-One Patients at a Single Center.

Inguinal lymphadenectomy is essential for staging and disease control. Minimally invasive techniques are recently replacing open techniques to reduce complications. We present our experience and lessons learnt from 21 patients who underwent lateral video endoscopic inguinal lymphadenectomy (L-VEIL) for penile malignancy. All patients above 18 years of age with histopathology-confirmed squamous cell carcinoma penis with stages ≥ T1b and T1a with persistent lymphadenopathy who underwent L-VEIL over a period of 2 years (2020-2022) were included. The data were analyzed on the basis of intraoperative and postoperative complications, lymph node yield, hospital stay, and histopathology report. Forty-one lower limbs of 21 patients underwent L-VEIL during the abovementioned period. Median age was 52 years. Mean operative time (on 1 side) was 80 minutes. Median lymph node yield per side was 7.2. Intraoperatively, 1 patient had a vascular injury at the saphenofemoral junction, requiring conversion to open. Postoperative complications were superficial surgical site infection (n=4), lymphedema (n=1), and lymphocoele (n=3), one of which was drained by pigtail catheter. One patient required exploration on the second postoperative day because of vascular injury. Average duration of hospital stay was 3 days. The median time of drain removal was 13 days. Histopathology suggested seminoma in 1 patient and mature teratoma in 1 patient; the rest of the patients' reports were negative for malignancy. The L-VEIL is safe and feasible, and there is a reduction (~30%) in complications; oncological outcomes are also not affected. It has better ergonomics, resulting in ease and comfort for surgeons when compared with classical VEIL.

Primary Closure Versus Delayed Primary Closure of Class III and IV Surgical Wounds Following Emergency Laparotomy: A Prospective Comparative Study.

Introduction Emergency surgery has a high risk of complications due to the detrimental effect of perioperative sepsis and the relative lack of preoperative optimization of patients. Despite advances in critical care for the management of sepsis, its prevention is dependent on various patient and surgeon factors. Surgical site infection continues to be a major determinant of morbidity and mortality following emergency abdominal surgery, especially in contaminated or dirty wounds. This study aims to compare two techniques of abdominal wall closure, primary closure with subcutaneous suction drains and delayed primary closure following negative pressure wound therapy, in terms of incidence of surgical site infection and morbidity. Materials and methods The study was a prospective comparative study including 50 patients with an acute surgical abdomen requiring laparotomy. The patients were randomized into two groups, Group A (n=25) who underwent primary closure, and Group B (n=25) who underwent delayed primary closure. In Group B patients, a vacuum-assisted closure device was applied in the subcutaneous space for five days prior to the closure of the skin. Outcomes were compared in terms of the incidence of superficial and deep surgical site infection, its association with diabetes mellitus, and the total duration of hospital stay. A chi-square test and an unpaired t-test were used for the test of significance. Results A total of 50 patients, comparable in age, were included in the study. The overall incidence of surgical site infection was significantly higher in patients of Group A as compared to Group B (p=0.0046). There was a positive correlation between diabetes mellitus and the occurrence of wound infection in both groups with the odds ratio being 2.67 and 2.38 respectively. The incidence of superficial wound infection was significantly higher in Group A when compared to Group B (52% versus 24%; p=0.04). Deep surgical site infection was higher in patients of Group A (20% versus 8%) but was not statistically significant (p=0.22). The average duration of hospital stay was 41.56 ± 6.96 and 37.86 ± 6.68 days for patients who developed complications fromGroups A and B respectively, while it was nearly two and a half times lower in uncomplicated cases of Groups A and B (11.71± 1.70 days and 16.58± 1.06 days respectively). The one-tailed unpaired t-test showed a significant difference in means of hospital stay between patients with and without complications (T: 17.06, critical value: 1.677). Conclusion Delayed primary closure is an effective method of managing contaminated and dirty wounds following emergency laparotomy. Negative pressure wound therapy is one technique for preventing wound bed infection and accelerating wound healing in such cases. By combining the above in emergency surgeries, the incidence of surgical site infection and duration of hospital stay can be significantly reduced.

Surgical Strategy for Sternal Closure in Patients with Surgical Myocardial Revascularization Using Mammary Arteries.

Coronary artery bypass grafting has evolved from all venous grafts to bilateral mammary artery (BIMA) grafting. This was possible due to the long-term patency of the left and right internal mammary demonstrated in angiography studies compared to venous grafts. However, despite higher survival rates when using bilateral mammary arteries, multiple studies report a higher rate of surgical site infections, most notably deep sternal wound infections, a so-called "never event". We designed a prospective study between 1 January 2022 and 31 December 2022 and included all patients proposed for total arterial myocardial revascularization in order to investigate the rate of surgical site infections (SSI). Chest closure in all patients was performed using a three-step protocol. The first step refers to sternal closure. If the patient's BMI is below 35 kg/m2, sternal closure is achieved using the "butterfly" technique with standard steel wires. If the patient's BMI exceeds 35 kg/m2, we use nitinol clips or hybrid wire cable ties according to the surgeon's preference for sternal closure. The main advantages of these systems are a larger implant-to-bone contact with a reduced risk of bone fracture. The second step refers to presternal fat closure with two resorbable monofilament sutures in a way that the edges of the skin perfectly align at the end. The third step is skin closure combined with negative pressure wound therapy. This system was applied to 217 patients. A total of 197 patients had bilateral mammary artery grafts. We report only 13 (5.9%) superficial SSI and only one (0.46%) deep SSI. The preoperative risk of major wound infection was 3.9 +/- 2.7. Bilateral mammary artery grafting was not associated with surgical site infection in a univariate analysis. We believe this strategy of sternal wound closure can reduce the incidence of deep surgical site infection when two mammary arteries are used in coronary artery bypass surgery.

A Rotation Alar Fold Flap for Cosmetic Nasal Plane Reconstruction: Description of the Technique and Outcome in Three Dogs.

Nasal planum reconstruction is a surgical challenge, and several surgical techniques have been described. The objective of this study was to describe the rotation alar fold flap technique and to report clinical outcomes in a short case series. The feasibility of the technique was first assessed in a canine cadaveric model. The rotation alar fold flap was obtained by a single sharp horizontal incision of the dorsolateral nasal cartilage, preserving the caudal mucosal attachment to the ventral nasal concha. The flap was then rotated ventro-medially for the reconstruction of the ventral aspect of the nasal planum unilaterally or bilaterally. The rotation alar fold flap technique was used following a subtotal or partial planectomy for excision of a squamous cell carcinoma or mast cell tumors in three dogs. No intraoperative complications were recorded. Superficial surgical site infection was reported in two cases and minor dehiscence was reported in one case. However, survival of the flap was not affected. The cosmetic and functional outcomes were considered very satisfactory in all cases. The rotation alar fold flap technique offers a safe, valuable, feasible, functional and aesthetically satisfactory alternative surgical option for selected cases of localized tumor involving the central and ventral planum.

Local Antibiotic Therapy for Open Long Bone Fractures: Appropriate Prophylaxis or Unnecessary Exposure for the Orthopedic Trauma Patient?

Prophylactic local antibiotic therapy (LAbT) to prevent infection in open long bone fracture (OLBF) patients has been in use for many decades despite lack of definitive evidence confirming a beneficial effect. We aimed to evaluate the effect of LAbT on outcomes of OLBF patients on a nationwide scale. In this retrospective analysis of 2017-2018 American College of Surgeons-Trauma Quality Improvement Program database, all adult (≥18 years) patients with isolated OLBF (non-extremity-Abbreviated Injury Scale < 3) were included. We excluded early deaths (<24 h) and those who had burns or non-extremity surgery. Outcomes were infectious complications (superficial surgical site infection, deep superficial surgical site infection, osteomyelitis, or sepsis), unplanned return to operating room, and hospital and intensive care unit length of stay (LOS). Patients were stratified into two groups: those who received LAbT and those who did not receive LAbT (No-LAbT). Propensity score matching (1:3) and chi-square tests were performed. A total of 61,337 isolated OLBF patients were identified, among whom 2,304 patients were matched (LAbT: 576; No-LAbT: 1,728). Both groups were similar in terms of baseline characteristics. Mean age was 43 ± 17 years, 75% were male, 14% had penetrating injuries, and the median extremity-Abbreviated Injury Scale was 1 (1-2). Most common fracture locations were tibia (66%), fibula (49%), femur (24%), and ulna (11%). About 52% of patients underwent external fixation, 79% underwent internal fixation, and 86% underwent surgical debridement. The median time to LAbT was 17 (5-72) h, and the median time to debridement was 7 (3-15) h (85% within 24 h). The LAbT group had similar rates of infectious complications (3.5% vs. 2.5%, P = 0.24) and unplanned return to the operating room (2.3% vs. 2.0%, P = 0.74) compared to the No-LAbT group. Patients who received LAbT had longer hospital LOS (16 [10-29] vs. 14 [9-24] days, P < 0.001) but similar intensive care unit LOS (4 [3-9] vs. 4 [2-7] days, P = 0.19). Our findings indicate that prophylactic LAbT for OLBF may not be beneficial over well-established standards of care such as early surgical debridement and systemic antibiotics. Prospective studies evaluating the efficacy, risks, costs, and indications of adjuvant LAbT for OLBF are warranted.

COVID-19 Pandemic Effects on Clinical Outcomes of Hip Fractures Among Pediatric and Adult Patients.

Little is known about the distribution and outcomes of hip fractures in pediatric patients during the COVID-19 pandemic. To study the clinical outcomes of both pediatric and adult patients who underwent hip fracture surgeries and determine the effects of changes surrounding the COVID-19 pandemic. Both pediatric and adult surgical hip fracture cases were analyzed from the pandemic year (2020) and the control year (2019) using the American College of Surgeons National Surgical Quality Improvement Program database. Between the prepandemic (control) and pandemic years, a total of 2,438 pediatric and 28,180 adult cases were compared. Pediatric patients had similar perioperative characteristics and outcomes between the two years. Significantly fewer hip fractures were reported among adults during the pandemic (p < .001). Preoperatively, more adult patients had ventilator dependence (p = .020), transfusions (p = .029), and systemic inflammatory response syndrome (p < .001) in 2020. Adult operations were more likely to be emergent in 2020 (p < .001) and adults had more severe disease states. Length of stay (p < .001) and the time from operation to discharge (p < .001) were significantly longer for the adult cohort in 2020. Mortality was also higher for adults during the first year of the pandemic (p = .003), and superficial surgical site infections became more common (p = .036). Pediatric hip fracture patients had similar clinical outcomes between 2019 and 2020. Adults with hip fractures presented in more serious clinical conditions, which resulted in higher mortality in 2020. Further studies could better clarify the reasons as to why adult hip fracture patients had markedly worse clinical course during the COVID year than pediatric patients.

Changes in Management at the Postoperative Visit After In-Office Wide Awake Local Anesthetic No Tourniquet Carpal Tunnel Release

Patients are commonly seen for two postoperative visits following carpal tunnel release (CTR), the first visit being at 1-2 weeks and the second at approximately 6 weeks. Our study aimed to determine if these visits led to changes in postoperative medical management. A retrospective review was conducted of 748 procedures performed in an in-office procedure room under wide awake local anesthetic no tourniquet between August 2020 and December 2022. Charts were reviewed for changes in management related to the patient's CTR. Management changes involving a separate diagnosis or solely an additional follow-up visit were classified as unrelated to postoperative CTR care. A total of 730 patients returned for follow-up. There were 100 patients (13.7 %) who had a CTR-related change in management at the first postoperative visit. Most management changes at this timepoint were due to superficial surgical site infection. There were 29 patients (4.0 %) who had a CTR-related change in management at their second postoperative visit, most commonly a referral to therapy for stiffness or hypersensitivity. While postoperative visits for CTR may have intangible benefits, changes in CTR-related care occur only in 17.7% of patients. Therapeutic IV.

Primary Reconstruction of Bladder Neck Transection and Vaginal Laceration Post Blunt Abdominal Injury a Case Report

Blunt abdominal injury is not uncommon in the paediatric population. The presentation can be immediate or delayed, and if not promptly recognized may be attended with complications such as septicaemia, shock or death. Simple, readily available and cheap imaging techniques such as abdominal radiograph and ultrasound scan still remain relevant in the diagnosis of blunt abdominal injuries where abdominal computerized tomography is unavailable or unaffordable. This can expedite the decision for an early surgical exploration. In girls, complete bladder neck transection with vaginal wall injury is a rarely reported and unusual association of blunt abdominal injury more so with delayed presentation in the absence of an associated pelvic fracture. This rare trauma entity in a child can pose a diagnostic difficulty leading to delayed presentation. This is a case of 3 year old girl with 3 weeks history of trauma to the abdomen from collapsed building fence during a heavy downpour. She later developed progressive abdominal distension with pain, constipation, vomiting, fever and drainage of clear fluid per vaginam. She had visited several hospitals but was managed non-operatively. Over the period the patient had some relief of symptoms until she presented to our facility with poorly defined features of peritonitis following a referral from a peripheral hospital. Abdominal ultrasound scan revealed intraperitoneal fluid collection. She was resuscitated and had exploratory laparotomy with primary reconstruction of the bladder neck transection and vaginal wall laceration. She did well immediate postoperative except for the superficial surgical site infection and during follow-up visits. Primary repair of traumatic bladder neck transection and vaginal wall laceration in paediatric patients with delayed presentation of blunt abdominal injury is a feasible option of management. However, long term follow up is recommended as secondary procedures may become necessary.

단일기관 증례 기반의 개두술 후 수술 부위 감염의 발생률과 미생 물학적 관점의 고찰

Background: Surgical site infection (SSI) is the most common healthcare-associated infection. Neurosurgical SSI results in severe morbidity and high mortality. This study aims to review our insti-tutional series of SSIs after cranial surgery, identify risk factors and pathogens, and enhance surgical outcomes through literature review.&#x0D; Materials and Methods: A retrospective, single-institutional study was conducted, craniotomy and craniectomy from January 2021 to December 2022 were included. Risk factors of all cases and pathogens, treatments, and outcomes of infected cases were collected and statistically analyzed.&#x0D; Results: Out of total 391 cases, 8 cases (2.0%) from six different type of surgeries, and diseases were diagnosed SSI. Four different pathogens were isolated, but pathogen was not identified in 4 cases (50.0%). The isolated pathogens included methicillin-sensitive Staphylococcus aureus , methicillin-resistant S. aureus , Bacillus cereus , and multi-drug resistant Acinetobacter baumannii . Among the eight cases, there were 2 cases (25.0%) of superficial SSI, 4 cases (50.0%) of deep SSI, and 2 cases (25.0%) of organ/space SSI. Two cases (25.0%) were managed with antibiotics alone, abscess was drained in 2 cases (25.0%), and revisional surgery was conducted in 4 cases (50.0%).&#x0D; Conclusions: Out of the 8 cases of SSI, a half of the isolated strains were multi-drug resistant. All infections were successfully treated without complications. However, guidelines for treatment of neu-rosurgical site infection were insufficient. The increasing prevalence of multi-drug resistant bacterial infection underscores the necessity of treatment consensus for the future.

Comparing the efficacy of chlorhexidine and povidone-iodine in preventing surgical site infections: A systematic review and meta-analysis.

Surgical site infections (SSIs) post-surgery impact patient health and raise healthcare costs. This meta-analysis examines the efficacy of antiseptics, chlorhexidine and povidone-iodine, in reducing SSIs, including various types, to settle ongoing debates on their comparative effectiveness. A systematic literature search conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines was executed on four established databases without temporal restrictions. Only randomized controlled trials (RCTs) including patients aged 18 years or older undergoing clean or potentially contaminated surgeries were included. Two independent evaluators carried out study selection, data extraction and quality assessment, adhering to Cochrane Collaboration's risk of bias tool. Statistical analyses were performed using chi-square tests and the I2 index to evaluate heterogeneity, and meta-analyses were conducted employing either fixed-effects or random-effects models as warranted by the heterogeneity assessments. A total of 16 RCTs were included after rigorous selection from an initial pool of 1742 articles. The studies demonstrated low levels of heterogeneity, supporting the use of a fixed-effects model. Chlorhexidine exhibited statistically lower rates of overall SSIs (RR 0.75; 95% CI 0.64-0.88; p < 0.001), superficial SSIs (RR 0.62; 95% CI 0.47-0.82; p < 0.001) and deep SSIs compared to povidone-iodine. The study furnishes compelling evidence in favour of chlorhexidine as a more efficacious antiseptic agent over povidone-iodine in minimizing the risk of various types of SSIs.
