Risk factors analyses associated with postoperative infection in choledochoscopy for intrahepatic bile duct stones (IHDs): a single-center retrospective study in real-world setting.

Choledochoscopy is a highly effective approach for managing intrahepatic bile duct stones (IHDs). However, postoperative infection is a common complication that significantly impacts treatment outcomes. Despite its clinical relevance, the risk factors associated with this procedure remain largely unexplored. This study focused on a consecutive cohort of patients who underwent choledochoscopy for IHDs at our institution between January 2016 and December 2022. The primary objective was to analyze the relationship between various clinical factors and postoperative infection, and to compare the postoperative infection of different choledochoscopic procedures. The study cohort consisted of 126 patients, with 60 individuals (47.6%) experiencing postoperative infection. Notably, preoperative biliary obstruction (odds ratio [OR] 1.861; 95% confidence interval [CI] 1.314-8.699; p = 0.010) and operation time (OR 4.414; 95% CI 1.635-12.376; p = 0.004) were identified as risk factors for postoperative infection. Additionally, biliary tract infections (60.00%) were primarily responsible for postoperative infection, with Escherichia coli (47.22%) being the predominant bacterial strain identified in bile cultures. Furthermore, biliary tract obstruction (OR 4.563; 95% CI 1.554-13.401; p = 0.006) and body mass index (BMI) (OR 1.186; 95% CI 1.015-1.386; p = 0.031) were determined to be independent risk factors for postoperative biliary tract infection. The occurrence of postoperative infection in patients undergoing choledochoscopy was primarily associated with the duration of the operation and the presence of preoperative biliary obstruction.

Antibiotic prescription in bone augmentation and dental implant procedures: a multi-center study

BackgroundAdherence to antibiotic recommendations and safety aspects of restrictive use are important components when combating antibiotic resistance. The primary aim of this study was to assess the impact of national guidelines on antibiotic prescriptions for bone augmentation procedures among dentists working at three specialized clinics. The secondary aim was to assess the occurrence of postoperative infections.MethodsMedical charts of 400 patients treated with bone augmentation were reviewed: 200 in the years 2010–2011 and 200 in 2014–2015. The Swedish national recommendations for antibiotic prophylaxis were published in 2012.ResultsThere was a wide variation in antibiotic regiments prescribed throughout the study. The number of patients treated with antibiotic prophylaxis in a single dose of 2 g amoxicillin, and treated as advocated in the national recommendations, was low and decreasing between the two time periods from 25% (n = 50/200) in 2010–2011 to 18.5% (n = 37/200) in 2014–2015. The number of patients not given any antibiotics either as a prophylactic single dose or during the postoperative phase increased (P < 0.001). The administration of a 3-7-days antibiotic prescription increased significantly from 25.5% in 2010–2011 to 35% in 2014–2015. The postoperative infection rates (4.5% and 6.5%) were without difference between the studied periods. Smoking and omitted antibiotic prophylaxis significantly increased the risk of postoperative infection. Logistic regression analyses showed that patient male gender and suffering from a disease were predictive factors for the clinician to adhere to the guidelines.ConclusionsAfter introduction of national recommendations for antibiotic prophylaxis before bone augmentation procedures, the patient group receiving a single preoperative dose decreased while the group not given antibiotic prophylaxis increased. There was no difference in occurrence of postoperative infections between the two time periods. The results indicate a need for educational efforts and strategies for implementation of antibiotic prudence and awareness among surgeons performing bone augmentation procedures.

CURRENT STRATEGIES IN THE PREVENTION OF POSTOPERATIVE INFECTIONS IN SPINAL SURGERY

This study aimed to analyze the strategies used to prevent postoperative infections in spinal surgery and evaluate their effectiveness in reducing the frequency of infections. The study design was retrospective and was conducted between January and December 2021 at the Department of Orthopedic &amp; Spine Surgery, Hayatabad Medical Complex. The study included a total of 90 patients who were divided into two groups based on the preventative techniques used. Group A (n=45) received standard preventive measures, such as preoperative antibiotics, accurate aseptic techniques, and postoperative wound care. In comparison, Group B (n=45) was given supplementary preventive measures such as antibiotic-impregnated bone grafts and wound irrigation with antiseptic solutions. The occurrence of postoperative infections, namely surgical site infections (SSIs) and deep wound infections, was documented and compared between the two groups. The mean age of patients in Group A was 55.2±8.6 years, while it was 57.8±9.2 years in Group B. Group A consisted of 27 (60%) male and 18 (40%) female patients, whereas Group B had 29 (64.44%) male and 16 (35.55%) female patients. Nine (20%) patients in Group A developed postoperative infections, while only three (6.7%) in Group B developed infections. The difference in postoperative infection incidence between the two groups was statistically significant (p&lt;0.05). Similarly, the incidence of SSIs was lower in Group B (4.4%) than in Group A (15.6%) (p&lt;0.05). Most patients in both groups (55.55% in Group A and 48.88% in Group B) received lumbar fusion surgery. Cervical fusion surgery was performed on 10 (22.22%) Group A patients and 12 (26.66%) Group B patients. Decompression surgery was performed on eight (17.77%) patients in Group A and nine (20%) individuals in Group B. The study's findings indicate that preventive techniques, such as antibiotic-impregnated bone grafts and wound irrigation with antiseptic solutions, can significantly reduce postoperative infections in spine surgery. However, further research is needed to determine the long-term effectiveness of these prevention approaches and explore alternative methods for preventing postoperative infections in spine surgery.

Perioperative Antibiotic Prophylaxis in Radical Prostatectomy: “Single-Shot” versus Multiday Regimen

Introduction: Perioperative antibiotic prophylaxis (AP) is common in radical prostatectomy (RP). Yet there is no standard recommendation in international guidelines due to poor evidence. It is of great importance that these perioperative AP are sufficiently checked and systemically validated. The objective of this study was to determine whether a “single-shot” (single-use) perioperative AP yields equivalent results compared to a multiday prophylaxis in RP regarding postoperative wound infections and urinary tract infections. Methods: 376 patients treated by RP at the University Medical Centre Mannheim, from 2014 to 2016, were included in this retrospective study. RP was performed either in a robotic-assisted or open manner. One group received an intravenous dose of perioperative AP with either ciprofloxacin or levofloxacin, continued by an oral dose of AP with ciprofloxacin or levofloxacin until catheter removal, while the other group received a single-shot intravenous perioperative AP with either ciprofloxacin or cefuroxime. Results: There was no significant difference regarding the occurrence of postoperative infections between both AP regimes (p = 0.5). Age, body mass index, and ASA classification did not differ significantly between both groups (p > 0.25). Except for surgery time (p < 0.05), perioperative parameters, such as the preoperative presence of germ-free urine culture, length of hospital stay, catheter time, drain lay time, Gleason score, and TNM stadium, did not differ significantly. Conclusion: The present study shows that perioperative single-shot AP does not entail any disadvantage compared to the multiday AP in terms of postoperative infections after RP.

Clinical Observation of Botulinum Toxin Type A Combined with Nanofat in Facial Rejuvenation Treatment

Objective: To investigate the efficacy of botulinum toxin type A combined with nanofat in the treatment of facial rejuvenation. Methods: from January 2020 to January 2021, 20 patients with facial wrinkles in our hospital (The First Affiliated Hospital of Dalian Medical University) were treated with botulinum toxin type A combined with nanofat, and the effect, duration and complications were observed. Results: After 1, 3 and 6 months of injection, the effective rates were 90%, 75% and 40%, respectively; there was no occurrence of postoperative infection, fat mass, granuloma, and other adverse reactions. Conclusion: Botulinum toxin type A combined with nanofat filling has a clear therapeutic effect in the facial rejuvenation treatment, and can improve the skin texture while improving wrinkles, which is worthy of further popularization and application in clinic.

Probiotic supplements and postoperative complications after tooth extractions and third molar surgery: a systematic review.

Probiotics have gained considerable attention as intervention for various conditions in dentistry. The purpose of this review is to evaluate the current literature on the efficacy of probiotic supplements for alleviating symptoms after tooth extractions and third molar surgery. We searched the PubMed and Google Scholar databases up to October 15, 2021 using pertinent keywords to retrieve relevant literature. Based on abstracts, the authors reviewed the full text papers, extracted key outcome data, and assessed the risk of bias. Four articles based on three RCT's were included of which three allowed compilation. There were no beneficial effects on the occurrence of postoperative infections or alveolitis, but we disclosed a significant trend towards less self-reported pain one week after the tooth extractions (RD -0.22; 95% CI -0.33; -0.11; P<0.05). Findings concerning swelling, discomfort and use of painkillers were inconsistent. Probiotic supplements may offer clinical benefits within oral surgery, such as alleviating pain after tooth extractions. However, the certainty of these findings was very low due to risk of bias, heterogeneity, and inconsistencies across the studies. Further and larger investigations are required to strengthen the level of evidence.

Prophylactic Use of Antibiotics for Postsurgical Infection in c-TACE and DEB-TACE High-Risk Patients: A Case-Control Study.

Objectives According to recent reports, prophylactic use of antibiotics is not always required in conventional transarterial chemoembolization (c-TACE). However, clinical evidence of prophylactic antibiotics in drug-eluting beads transarterial chemoembolization (DEB-TACE) to prevent postsurgical infection is limited. This study is aimed to evaluate the correlation between the preoperative prophylactic application of antibiotics and postoperative infection in c-TACE or DEB-TACE, especially in a population with a high risk for postsurgical infection. Methods In this retrospective study, TACE patients diagnosed with hepatic carcinoma (between January 2019 and May 2021) were examined. The case group was given 1.5 g cefuroxime sodium 0.5–1 hour before TACE, while there was no intervention in the control group. The outcomes analyzed were leukocyte count >9.5 × 109/L on the second day after the operation and the diagnosis of infection within one month after the operation. We applied univariate, multivariate logistic regression, trend analysis, and subgroup analysis to find potential risk factors and the necessity of prophylactic antibiotics. Results Among 142 eligible cases, 72 received antibiotics while 70 were kept as control, 113 cases were treated with c-TACE, and 29 were treated with DEB-TACE. Multivariate analysis showed that the increase in white blood cell count after the operation was related to diabetes (OR 5.112, 95% CI 1.229–21.264, p = 0.025). The occurrence of postoperative infection was negatively correlated with preoperative albumin value (＜25 g/L) (OR 153.118, 95% CI 1.631–14372.331, p = 0.030). Trend analysis showed that the risk of postoperative infection increased with a decrease in serum albumin level (P < 0.05). Subgroup analysis showed that there were no significant differences in the incidence of increased leukocyte count and postoperative infection between the prophylactic and nonprophylactic treatment groups, in the case of diabetes, preoperative albumin levels, and operation mode (P > 0.1). Conclusions Prophylactic antibiotic treatment before the c-TACE or DEB-TACE had no significant correlation with postoperative leukocyte increase and postoperative infection. Diabetes history and serum albumin levels were the prominent risk factors associated with an increase in postoperative leukocyte count and postoperative infection. Future large-scale studies and randomized-controlled trials are required to confirm and validate this association.

Frequency and characteristics of bacterial and viral low-grade infections of the intervertebral discs: a prospective, observational study

Study designMonocentric, prospective, observational study.ObjectiveThe clinical relevance of bacterial colonization of intervertebral discs is controversial. This study aimed to determine a possible relationship between bacterial and viral colonization and low-grade infection of the discs.MethodsWe investigated 447 disc samples from 392 patients. Microbiological culture was used to examine the samples for bacterial growth, polymerase chain reaction (PCR) was used for detection of herpes simplex virus types 1 and 2 (HSV-1, HSV-2) and Cytomegalovirus (CMV), and histopathological analysis was used to detect signs of inflammation. The results were compared between subgroups organized according to gender, age, location of the samples, surgical approach, preoperative C-reactive protein (CRP), preoperative and 6 months postoperative Oswestry Disability Index (ODI) and Neck Disability Index (NDI), and Modic changes (MC) of the corresponding endplates. Also, we assessed the occurrence of postoperative infections within 6 months.ResultsMicrobiological culture was positive in 38.78% of the analyzed intervertebral discs. Altogether, 180 bacteria were isolated. Coagulase-negative staphylococci (CONS) (23.41%) and Cutibacterium acnes (18.05%) were the most frequently detected microorganisms. None of HSV-1, HSV-2, or CMV were detected. Male patients (p = 0.00036) and cervical segments (p = 0.00001) showed higher rates of positive culture results. Ventral surgical approaches ( p < 0.001) and Type 2 MC (p = 0.0127) were significantly associated with a positive microbiological result ( p< 0.001). Neither pre- nor postoperative ODI and NDI are associated with positive culture results. In 4 (1.02%) patients, postoperative spondylodiscitis occurred.ConclusionsWith 447 segments from 392 patients, we present one of the largest studies to date. While disc degeneration caused by HSV-1, HSV-2, and CMV seems unlikely, we found positive microbiological culture results in 38.78% of all discs. The role of local skin flora and sample contamination should be the focus of further investigations.Level of EvidenceIII.Trial registration: The study was registered at ClinicalTrials.gov (ID: NCT04712487, https://www.clinicaltrials.gov/ct2/show/study/NCT04712487).

Risk factors for postoperative infection after combat related head injuries

Introduction &#x0D; The prevalence of penetrating head injuries (PBI) has increased during the latest wars making up to 37,4% of all injuries (1,2) Microbiology of modern war wounds is unique for each military conflict depending on the climatic and geographical features of the theater of combat (3,4).&#x0D; Material and methods: &#x0D; 286 patients were operatively treated after penetrating combat injury in our institution between 1991-1999. Based on the inclusion criteria: combat-related cranial injury and absence of severe abdominal or chest combat injuries, as well as their ability to report for a follow-up exam led to the inclusion of 202 patients. Initial surgical treatment included removal of devitalized soft tissue and bone fragments with craniectomy, removal of devitalized brain tissue, easily accessible intracerebral bone and metal fragments and intracranial hemathoma. All patients received the same standardized postoperative care with triple antibiotics.&#x0D; Results&#x0D; &#x0D; Infection occurred in 36 patients (17,82%). In vast majority of the cases infection occurred in the form of brain abscess 31 (86.11%), in 4 cases as meningitis (11.1%) and in 1 case as osteomyelitis and epidural infection (2.78%). Retained metal and bone fragments and postoperative liquorrhea have significant influences on occurrence of postoperative infection. &#x0D; &#x0D; Conclusion&#x0D; &#x0D; Postoperative infection considerably increases long term functional outcome. Using advantages of minimally invasive surgical technique, neuronavigation or intraoperative imaging for removal of retained foreign bodies can reduce risk for postoperative infection with minimal risk of additional neurologic deficit. Autograft is preferable option for dural reconstruction in combat related head injuries.

One dose of preoperative, intravenous, prophylactic antibiotics significantly lowers postoperative infection rate in septoplasty-a study of 772 operations.

Postoperative infection is the most common complication after septoplasty. Pre- or postoperative prophylactic antibiotics are commonly used, although no official guidelines exist. We retrospectively collected data on postoperative infections from 772 septoplasties performed in 2015, 2016 and 2018, and classified the infections according to surgical site infection (SSI) criteria by the Centers for Disease Control and Prevention (CDC). We evaluated the infections according to antibiotic use (preoperative or postoperative, both, or none) and accounted for patient and surgical confounding factors. We compared the results with three previous studies from our department to find out the trend in the occurrence of postoperative infections and in the use of antibiotics. Twenty-nine cases (3.8%) fulfilled CDC infection criteria. Any kind of antibiotic prophylaxis reduced the risk of SSI (p=.018). One dose of intravenous cefuroxime before incision was the most effective preventive measure (p=.045). We found no significant effect of postoperative antibiotics. However, postoperative antibiotics lowered the infection rate to 1.8% compared to 6.1% among those not treated with any antibiotics. The only other factor reducing the risk of SSI was local anaesthesia compared with general anaesthesia. Preoperative antibiotic prophylaxis effectively reduced postoperative infection rate after septoplasty.

Randomized comparative study in the treatment of oral leucoplakia with laser and conventional surgery

Objective: High-energy lasers are used as an alternative to surgical treatment of potentially malignant disorders in the oral cavity. The present article aims to make a prospective randomised comparative clinical assessment of the effect of laser surgery and conventional surgery in the treatment of oral leukoplakia (OL). Materials and methods: In the study were included 89 patients with histologically confirmed oral leukoplakia lesions. Laser excision of the lesions using Er YAG laser was performed in 36 of the patients, while standard surgical excision was used in 53 of the cases. Following clinical assessment comparing the two treatment methods was conducted based on: pain, wound healing, infection and recurrence of the lesions. Results: A statistically significant difference between two groups according pain in the postoperative period was found. Patients treated with laser ablation experienced far less pain than those treated with surgical excision. The healing time was significantly faster in the group treated with Er YAG laser, and regarding the occurrence of postoperative infections, the results of the two methods did not differ significantly. Recurrence was observed earlier in the group treated with laser ablation, but the levels align over a longer period of time. Conclusion: Er YAG laser ablation is a contemporary method for the treatment of oral leukoplakia without dysplasia, providing similar success, compared to conventional surgical excision, with less postoperative discomfort for the patients. Keywords Er YAG laser; Leukoplakia; Potentially malignant disorders.

Nasal Microbiota and Infectious Complications After Elective Surgical Procedures

The association of the nasal microbiome with outcomes in surgical patients is poorly understood. To characterize the composition of nasal microbiota in patients undergoing clean elective surgical procedures and to examine the association between characteristics of preoperative nasal microbiota and occurrence of postoperative infection. Using a nested matched case-control design, 53 individuals who developed postoperative infection were matched (approximately 3:1 by age, sex, and surgical procedure) with 144 individuals who were not infected (ie, the control group). The 2 groups were selected from a prospective cohort of patients undergoing surgical procedures at 2 tertiary care university hospitals in Baltimore, Maryland, who were at high risk for postoperative infectious complications. Included individuals were aged 40 years or older; had no history of autoimmune disease, immunocompromised state, immune-modulating medication, or active infection; and were scheduled to undergo elective cardiac, vascular, spinal, or intracranial surgical procedure. Data were analyzed from October 2015 through September 2020. Nasal microbiome cluster class served as the main exposure. An unsupervised clustering method (ie, grades of membership modeling) was used to classify nasal microbial samples into 2 groups based on features derived from 16S ribosomal RNA gene sequencing. The microbiome cluster groups were derived independently and agnostic of baseline clinical characteristics and infection status. Composite of surgical site infection, bacteremia, and pneumonia occurring within 6 months after surgical procedure. Among 197 participants (mean [SD] age, 64.1 [10.6] years; 63 [37.7%] women), 553 bacterial taxa were identified from preoperative nasal swab samples. A 2-cluster model (with 167 patients in cluster 1 and 30 patients in cluster 2) accounted for the largest proportion of variance in microbial profiles using grades of membership modeling and was most parsimonious. After adjusting for potential confounders, the probability of assignment to cluster 2 was associated with 6-fold higher odds of infection after surgical procedure (odds ratio [OR], 6.18; 95% CI, 3.33-11.7; P < .001) independent of baseline clinical characteristics, including nasal carriage of Staphylococcus aureus. Intrasample (ie, α) diversity was inversely associated with infectious outcome in both clusters (OR, 0.57; 95% CI, 0.42-0.75; P < .001); however, probability of assignment to cluster 2 was associated with higher odds of infection independent of α diversity (OR, 4.61; 95% CI, 2.78-7.86; P < .001). These findings suggest that the nasal microbiome was an independent risk factor associated with infectious outcomes among individuals who underwent elective surgical procedures and may serve as a biomarker associated with infection susceptibility in this population.

Recursive partitioning analysis of factors determining infection after intracranial tumor surgery

ObjectivesSeveral factors are commonly associated with the occurrence of post-operative infection after craniotomy. However, the risk factors associated with tumor surgery have been less intensively investigated. The aim of the present study was to analyze the risk factors for infection and categorize patients according to risk rate. MethodsIn this study, we retrospectively evaluated 987 adult patients consecutively submitted to craniotomy for tumor resection. The primary outcome was the occurrence of infection within 30 days after surgery. The following independent variables were assessed: age, gender, surgery duration, length of hospital stay prior to surgery, reoperation, body mass index, serum albumin, hemoglobin, lactic dehydrogenase, smoking, diabetes, corticoid use, preoperative chemotherapy, previous irradiation, elective or urgent indication for surgery, supra or infratentorial lesion location, and tumor histology. We performed a recursive partitioning analysis to assess the relative importance of these variables in predicting infection. ResultsThe model returned a 3-level classification: 1. CSF-leakage (relative contribution 70%), 2. Emergency surgery indication (18%), and 3. Tumor histology (8%). Additionally, partitioning clustered together 3 risk groups: 1. CSF-leakage group (probability of infection 72.5%), 2. No CSF-leakage and urgent surgery (mean probability 18.1%); and 3. no CSF-leakage and no urgent surgery (3.4%). The misclassification rate was 4.5%, the overall specificity and sensitivity were 99.6% and 75.5%, respectively, and the area under the ROC-curve was 0.6908. ConclusionOur analysis indicates that technical and treatment-related factors are significantly more relevant than patient- or disease-related factors in determining the risk of postoperative infection.

Preoperative C-reactive protein to albumin ratio and oral health in oral squamous cell carcinoma patients

BackgroundThe C-reactive protein to albumin (CRP/alb) ratio can predict early survival of a hospitalized patient. We evaluated factors that influence the preoperative CRP/alb ratio in oral squamous cell carcinoma (OSCC) patients and in particular clarified the role of oral health to this ratio.Materials and methodsData from surgically treated OSCC patients were collected retrospectively. The outcome variables were preoperative CRP/alb ratio, CRP level, and alb level. The studied predictors were total number of teeth, periodontal stability, marginal bone loss, tumour stage, T-class, lymph node status, and site. The statistical significance of age, sex, comorbidity combination of age and disease history (Charlson Comorbidity Index [CCI]), smoking, and alcohol history for outcome variables were evaluated. Patient 3-month mortality and occurrence of postoperative infections were recorded.ResultsA total of 159 patients were included in the study. The early mortality was 3.8%. CRP/alb was higher in these patients than in those who survived. The only independent variables for CRP/alb changes were CCI and heavy alcohol use. The CRP/alb ratio was significantly lower in non-heavy alcohol users (odds ratio [OR] 0.114, 95% confidence interval [CI] 0.024–0.541; adjusted p = 0.006) than in other patients. Patients with CCI 0–1 were more likely to have a lower CRP/alb ratio than patients with CCI ≥ 5 (OR 0.033, 95% CI 0.004–0.284; adjusted p = 0.002). In addition, high CRP/alb ratio associated with postoperative infections (p = 0.026).ConclusionsThe CRP/alb ratio was high in OSCC patients with combined comorbities of age and disease history and in patients with heavy alcohol use. Oral health or tumour-related variables did not independently affect the CRP/alb ratio. The CRP/alb ratio appears suitable for prediction of OSCC patient early survival.

The A2B trial, antibiotic prophylaxis for excision-graft surgery in burn patients: a multicenter randomized double-blind study

BackgroundThe indication for antibiotic prophylaxis in burn patients remains highly controversial, with no consensus having been reached. The objective of antibiotic prophylaxis is to reduce the risk of postoperative local and systemic infections. Burn surgery is associated with a high incidence of bacteremia, postoperative infections, and sepsis. However, antibiotic prophylaxis exposes patients to the risk of selecting drug-resistant pathogens as well as to the adverse effects of antibiotics (i.e., Clostridium difficile colitis). The lack of data precludes any strong international recommendations regarding perioperative prophylaxis using systemic antibiotics in this setting.The goal of this project is therefore to determine whether perioperative systemic antibiotic prophylaxis can reduce the incidence of postoperative infections in burn patients.MethodsThe A2B trial is a multicenter (10 centers), prospective, randomized, double-blinded, placebo-controlled study. The trial will involve the recruitment of 506 adult burn patients with a total body surface area (TBSA) burn of between 5 and 40% and requiring at least one excision-graft surgery for deep burn injury. Participants will be randomized to receive antibiotic prophylaxis (antibiotic prophylaxis group) or a placebo (control group) 30 min before the incision of the first two surgeries. The primary outcome will be the occurrence of postoperative infections defined as postoperative sepsis and/or surgical site infection and/or graft lysis requiring a new graft within 7 days after surgery. Secondary outcomes will include mortality at day 90 postrandomization, skin graft lysis requiring a new graft procedure, postoperative bacteremia (within 48 h of surgery), postoperative sepsis, postoperative surgical site infection, number of hospitalizations until complete healing (> 95% TBSA), number of hospitalization days living without antibiotic therapy at day 28 and day 90, and multiresistant bacterial colonization or infection at day 28 and day 90.DiscussionThe trial aims to provide evidence on the efficacy and safety of antibiotic prophylaxis for excision-graft surgery in burn patients.Trial registrationClinicalTrials.gov NCT04292054.

Retrospective Analysis of Complication Rates Associated With Auricular Reconstruction After Skin Cancer Surgery.

There is limited data regarding postoperative complications after microtia surgery or tympanoplasty; however, complication rates after pinna reconstruction following tumor resection and comorbidities associated with suboptimal outcomes have not been investigated so far. To examine the incidence of postoperative complications after auricular reconstruction surgery following tumor resection and determine the association between postoperative complications and defect size, patients' comorbidities, and reconstruction type. In a retrospective case series (n = 146, January 2014 to October 2018), we examined the surgical outcome and amount of postoperative complications following auricular surgery as well as the association with different comorbidities. SPSS 16.0 was used for statistical analyses. The following early postoperative complications were identified: pain (29.5%), hematoma (4.1%), flap congestion (4.8%), infection (3.4%), and flap/graft necrosis (2.7%). Late complications including cartilage step-offs, helical rim sulcus alteration, granulomas, or ear deformities occurred only in 3.6% of subjects. Reconstructions of large defects (>1 cm2) were associated with a higher incidence of early postoperative complications compared to small defects (<1 cm2) (P < .001). Neither the presence of smoking or diabetes nor immunosuppression was significantly linked to an increased incidence of early complications. Immunosuppression, however, was associated with a higher incidence of postoperative infection (P < .001). The incidence of early and late postoperative complications after skin tumor resection and external ear reconstruction is low. The occurrence of postoperative infection was not linked with smoking or the presence of diabetes, but strongly associated with a state of immunosuppression, which is why a perioperative antibiotic prophylaxis in immune-compromised patients may be considered.

The Change of Laboratory Tests Could Be Predictive Factors for Infection after McKeown Esophagogastrectomy.

Aim To analyze whether the change of laboratory tests (postoperative day 1 (POD1) minus pre-operation) could be predictive factors for postoperative infection in patients who have undergone McKeown esophagogastrectomy. Methods We retrospectively investigated the clinical data of 358 patients who have undergone McKeown esophagogastrectomy, and divided them into infection and noninfection groups. SPSS 22.0 software was performed for data analysis. Results In the two groups, smoking status (66.7% vs. 42.3%; P = 0.014), male gender (86.1% vs. 72.0%; P < 0.001), hoarseness (23.6% vs. 8.7%; P < 0.001), poor coughing ability (51.4% vs. 9.1%; P < 0.001), the change of WBC count (5.59 ± 4.75 × 109/L vs. 4.51 ± 4.11 × 109/L; P = 0.05), the change of glucose (6.03 ± 3.97 g/L vs. 3.78 ± 3.18 g/L), the change of ALB (−12.83 ± 3.45 g/L vs. −10.69 ± 3.86 g/L), the change of CRE (0.17 ± 19.94 umol/L vs. −4.02 ± 15.40 umol/L, P = 0.047) were significantly different. These factors were assessed using logistic regression analysis, and factors with P ≤ 0.05 in the univariate analysis were entered into multivariate analysis based on the forward stepwise (conditional) method. Poor coughing ability (odds ratio [OR], 11.034, 95% confidence interval [CI], 5.358–22.724), smoking status (OR, 4.218; 95% CI, 2.110–8.431), the change of WBC count (OR, 1.079; 95% CI, 1.000–1.164), the change of serum ALB level (OR, 0.849; 95% CI, 0.772–0.935), and the change of blood glucose levels (OR, 1.237; 95% CI, 1.117–1.371) were determined as independent risk factors for postoperative infection. We established a scoring system based on these 5 factors, and the area under the curve for this predictive model was 0.843 (range, 0.793–0.894); the sensitivity, specificity, and cut-off score were 70.8%, 85.3%, and 2.500, respectively. Conclusion Poor coughing ability, smoking habit, the high change of WBC and blood glucose levels, and low change of serum ALB levels can be used to predict the occurrence of postoperative infections among patients who have undergone McKeown esophagogastrectomy.

The Relative Role of Bile Bacterial Isolation on Outcome in Stent-Bearing Patients Undergoing Pancreatoduodenectomy

BackgroundBiliary stenting leads to antimicrobial-resistant (AMR) microorganism retrievement in bile cultures. However, the impact of intraoperative bile colonizations on post-pancreaticoduodenectomy complications remains unclear. Aims of our study were to characterize the bile flora of stented patients in comparison with postoperative cultures and to analyze whether patterns of drug resistance affected postoperative outcomes. MethodsWe analyzed records from stent-bearing pancreaticoduodenectomy patients at 3 European centers. Intra- and postoperative cultures were compared and classified as multidrug sensitive (MDS), multidrug resistant (MDR), and extensively drug resistant (XDR). Thirty-day complications were graded according to international standards. ResultsOut of 270 patients, intraoperative cultures were positive in 219 (81.1%) cases. In 36.7%, MDS species were isolated; in 35.9%, MDR; and in 8.5%, XDR species. A solid correspondence between the species isolated intra- and postoperatively (p < 0.001) was observed. Intraoperative MDR/XDR isolation was associated with an increased rate of surgical (p = 0.043) and infectious complications (p = 0.030), but not severe complication rate (p = 0.973). Postoperative MDR/XDR isolation was associated with higher risk of major complications (45.6% vs. 15.8%, p < 0.001), postoperative pancreatic fistula (p < 0.001), and post-pancreatectomy hemorrhage (p = 0.002). By multivariate analysis, intraoperative AMR isolation was associated with high likelihood of postoperative AMR infections. However, only in 43/121 cases, intraoperative MDR/XDR microorganisms turned into the occurrence of postoperative infections. ConclusionIntraoperative AMR isolates do not translate into severe outcomes, despite being significantly associated with surgical and infectious complications.
