ABSTRACT
Identifying predictors for surgical site infections (SSIs) after emergency surgical treatment for traumatic pulmonary haemorrhage (TPH) is crucial for improving patient outcomes. This study aims to ascertain these predictors. In this comprehensive retrospective study, conducted from January 2020 to December 2023 at our institution, 75 patients were analysed, including a case group of 25 patients with SSIs and a control group of 50 without SSIs post-TPH surgery. Inclusion criteria focused on patients aged 18 and above undergoing thoracotomy or minimally invasive thoracic surgery for TPH. Exclusion criteria included compromised immune systems, chronic pulmonary diseases, prior thoracic surgery or active infections at admission. We assessed several predictors: anaemia; operation time over 2 h; hospital stay over 5 days; intraoperative blood loss exceeding 500 mL; body mass index (BMI) ≥25 kg/m2; age ≥ 50 years; use of surgical drains; the presence of open wounds; diabetes mellitus and non-prophylactic antibiotic use. Statistical analysis involved univariate and multivariate logistic regression, using SPSS Version 27.0. Univariate analysis revealed significant associations between SSIs and surgical drain placement, diabetes mellitus, open wounds and non-prophylactic antibiotic use (p < 0.01). Multivariate analysis confirmed these factors as significant predictors of SSIs, with notable odds ratios. Other variables like anaemia, extended hospital stay, excessive intraoperative blood loss, older age and higher BMI did not significantly predict SSIs. Significant predictors for SSIs following TPH surgery include surgical drain placement, diabetes mellitus, open wounds and non-prophylactic antibiotic use. Identifying and managing these risks is crucial in clinical practice to reduce SSIs incidence and improve patient outcomes.

Surgical site infections (SSIs) following radical mastectomy in breast cancer patients can significantly affect patient recovery and healthcare resources. Identifying and understanding the risk factors for postoperative wound infections (PWIs) are crucial for improving surgical outcomes. This retrospective study was conducted from June 2020 to June 2023, including 23 breast cancer patients who developed PWIs post-radical mastectomy and a control group of 46 patients without such infections. Comprehensive patient data, including variables such as intraoperative blood loss, hospital stay duration, body mass index (BMI), operation time, anaemia, drainage time, diabetes mellitus, cancer stage, white blood cell (WBC) count, serum albumin levels and preoperative neoadjuvant chemotherapy, were meticulously gathered. Statistical analyses, including univariate and multivariate logistic regression, were performed using SPSS software (Version 27.0). The univariate analysis identified several factors significantly associated with an increased risk of PWIs, including preoperative neoadjuvant chemotherapy, low serum albumin levels, advanced cancer stage, diabetes mellitus and reduced WBC count. Multivariate logistic regression highlighted anaemia, prolonged drainage time, diabetes mellitus, advanced cancer stage, reduced WBC count, hypoalbuminemia and preoperative neoadjuvant chemotherapy as significant contributors to the increased risk of PWIs. Anaemia, extended drainage time, diabetes mellitus, advanced cancer stage, low WBC count, hypoalbuminemia and preoperative neoadjuvant chemotherapy are key risk factors for SSIs post-radical mastectomy. Early identification and proactive management of these factors are imperative to reduce the incidence of postoperative infections and enhance recovery outcomes in breast cancer patients.

Varicose veins are the prevalent vascular disorder that has conventionally been managed via risky postoperative wound infections and conventional surgery. While ultrasound-guided microwave ablation (UMA) has gained attention as a minimally invasive alternative, there is still a lack of research examining its comparative effectiveness. A prospective comparative investigation was undertaken in the Zhejiang region of China from January to November 2023, involving 140 patients who had received the diagnosis of primary varicose veins. An equal number of 70 patients underwent UMA and conventional surgery. Exclusion criteria for the study encompassed adult patients aged 18-65, with the exception of those who had undergone prior venous surgery, deep vein thrombosis or peripheral arterial disease. The demographical characteristics, procedural details and complication profiles of patients who developed postoperative wound infections within 30 days were analysed statistically. The outcomes demonstrated that postoperative wound infections were significantly diminished (5.7%) with UMA in comparison to conventional surgery (17.1%). In addition, the average duration of procedures and length of hospital stay for UMA patients were both reduced, although neither of these differences was found to be statistically significant (p > 0.05). Infection management, age and gender distribution of varicose veins were comparable between the two groups (p > 0.05). A significant inverse correlation was observed between the severity of varicose veins and postoperative outcomes, as determined by the regression analysis (p < 0.05). Using UMA to treat varicose veins showed promise as an alternative to conventional surgery, specifically in minimizing the incidence of postoperative wound infections. Additional research and clinical consideration are needed regarding the potential transition toward minimally invasive techniques in treatment of varicose veins, as suggested by these results.

Postoperative wound infections (PWIs) following open reduction and internal fixation (ORIF) for elbow fractures can significantly affect patient outcomes. Identifying associated risk factors is crucial for improving clinical practices and patient care. A retrospective analysis (June 2020-June 2023) at our institution involved 90 patients who underwent elbow ORIF. Thirty patients developed PWIs (case group), compared to 60 who did not (control group). Variables like anaemia, operation duration, hospital stay, blood loss, body mass index (BMI), age, hypoalbuminemia, smoking status, diabetes mellitus and open fractures were examined. Univariate and multivariate analyses determined the impact of these variables on PWI incidence, with statistical significance set at p < 0.05. The main pathogens identified were Escherichia coli among Gram-negative bacteria (59.46%) and Staphylococcus aureus among Gram-positive bacteria (40.54%). In the univariate analysis, hypoalbuminemia, anaemia, and lifestyle factors such as smoking showed higher prevalence in patients with PWIs. However, age and length of hospital stay did not significantly influence infection rates. The multivariate analysis further elucidated that anaemia, smoking, diabetes mellitus and open fractures were independent, significant predictors of PWIs. These findings highlight the complexity of factors influencing infection risk post-ORIF, underscoring the importance of both individual health conditions and surgical complications in patient outcomes. Anaemia, smoking, diabetes mellitus and open fractures significantly increase the risk of PWI after elbow ORIF. Early identification and management of these risk factors are imperative to reduce infection rates and improve postoperative recovery.

Lung cancer remains a leading cause of cancer-related mortality, with surgical resection as a primary treatment modality. However, postoperative wound infections (PWIs) pose significant risks following thoracoscopic radical resection. This study aims to identify the risk factors and pathogenetic characteristics associated with PWIs in lung cancer surgery. A comprehensive retrospective study was conducted from August 2021 to June 2023 at our institution. The study included 30 patients who developed PWIs and 60 controls who did not, following thoracoscopic radical resection for lung cancer. We evaluated various factors including age, hospital stay, intraoperative blood loss, body mass index (BMI), operation time, prophylactic antibiotic use, diabetes mellitus and tumour staging. Diagnostic criteria for PWIs were based on clinical signs and microbiological confirmation. Statistical analysis was performed using SPSS software, utilizing chi-square tests, and univariate and multivariate logistic regression analyses. The predominant pathogens identified in PWIs were Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Univariate analysis revealed operation time (≥4 h) and diabetes mellitus as significant risk factors for PWIs, while prophylactic antibiotic use was associated with a lower incidence of PWIs. Multivariate analysis further confirmed these findings, highlighting prolonged operation time and diabetes as significant predictors of PWIs, and antibiotic use as a protective factor. Prolonged operation time and diabetes mellitus significantly increase the risk of PWIs following thoracoscopic radical resection for lung cancer, whereas prophylactic antibiotics play a protective role. These findings underscore the importance of tailored preventive strategies in clinical practice to minimize the occurrence of postoperative infections and improve surgical outcomes in lung cancer patients.

Selective IgM deficiency is a rare immunological disorder, with patients presenting with recurrent infections and allergic manifestations. However, the association with early postoperative infection has not been widely reported in the literature. We describe a rare case of a patient who had an early wound infection 1 day after excision of a Merkel cell carcinoma from his right buttock and was later found to have decreased IgM levels. Selective IgM deficiency should therefore be considered in patients presenting with recurrent infections or in patients who have previously undergone surgery and subsequently developed early infection postoperatively. In this subset of patients, extra precautions may need to be taken pre- and postoperatively to reduce the risk of developing a postoperative infection.

Surgical site infections (SSI) are commonly seen in surgical practice and are the main cause for concern in post-operative patients. There are many risk factors that predispose to the development of SSI. However, the occurrence of SSI in patients undergoing elective class I and class II surgeries, which are considered clean surgeries with minimal contamination, is an important issue bothering the surgeons. SSI are also responsible for increased morbidity due to wound dehiscence, thus prolonging hospital stays and often leading to inconvenience to patients. We hereby present a study to highlight and address this important issue of SSI in our institute. All patients above 12 years of age who underwent elective class I and class II surgeries in the department of general surgery were included in this observational study. After surgery, local examination of the incision or wound site and grading of the SSI were done using the Southampton Wound Grading System (SWGS). Our results showed that 90% of the patients had normal healing, according to SWGS. We found that the incidence of SSI was lower in patients who underwent alternate-day dressing of their wound as compared to daily dressing. Another interesting finding was that the incidence of SSI was lower in patients in whom wound dressing was done with transparent film dressing as compared to povidone-iodine-guaze dressing. We concluded our study by finding that the incidence of SSI after elective class I and class II surgeries in our hospital was quite low, at 10%.
ABSTRACT
INTRODUCTION@#The superiority of laparoscopic repair over open repair of incisional hernias (IHs) in the elective setting is still controversial. Our study aimed to compare the postoperative outcomes of laparoscopic and open elective IH repair in an Asian population.@*METHODS@#This retrospective study was conducted in an acute general hospital in Singapore between 2010 and 2015. Inclusion criteria were IH repair in an elective setting, IHs with diameter of 3-15 cm, and location at the ventral abdominal wall. We excluded patients who underwent emergency repair, had recurrent hernias or had loss of abdominal wall domain (i.e. hernia sac containing more than 30% of abdominal contents or any solid organs). Postoperative outcomes within a year such as recurrence, pain, infection, haematoma and seroma formation were compared between the two groups.@*RESULTS@#There were 174 eligible patients. The majority were elderly Chinese women who were overweight. Open repair was performed in 49.4% of patients, while 50.6% underwent laparoscopic repair. The mean operation time for open repair was 116 minutes (116 ± 60.6 minutes) and 139 minutes (136 ± 64.1 minutes) for laparoscopic repair (P = 0.079). Within a year after open repair, postoperative wound infection occurred in 15.1% of the patients in the open repair group compared to 1.1% in the laparoscopic group (P = 0.0007). Postoperative pain, recurrence and haematoma/seroma formation were comparable.@*CONCLUSION@#Elective laparoscopic IH repair has comparable outcomes with open repair and may offer the advantage of reduced postoperative wound infection rates.

PURPOSE@#Periprosthetic fracture (PPF) is a serious complication that occurs in 0.3%-2.5% of all total knee arthroplasties used to treat end-stage arthritis. To our knowledge, there are no studies in the literature that evaluate the association between time to surgery after PPF and early postoperative infections or deep vein thrombosis (DVT). This study tests our hypothesis that delayed time to surgery increases rates of postoperative infection and DVT after PPF surgery.@*METHODS@#Our study cohort included patients undergoing PPF surgery in the American College of Surgeons National Surgical Quality Improvement Program database (2006-2015). The patients were dichotomized based on time to surgery: group 1 with time ≤2 days and group 2 with time >2 days. A 2-by-2 contingency table and Fisher's exact test were used to evaluate the association between complications and time to surgery groups, and multivariate logistic regression was used to adjust for demographics and known risk factors.@*RESULTS@#A total of 263 patients (80% females) with a mean age of 73.9 ± 12.0 years were identified receiving PPF surgery, among which 216 patients were in group 1 and 47 patients in group 2. Complications in group 1 included 3 (1.4%) superficial infections (SI), 1 (0.5%) organ space infection (OSI), 1 (0.5%) wound dehiscence (WD), and 4 (1.9%) deep vein thrombosis (DVT); while complications in group 2 included 1 (2.1%) SI, 1 (2.1%) OSI, 1 (2.1%) DVT, and no WD. No significant difference was detected in postoperative complications between the two groups. However, patients in group 2 were more likely (p = 0.0013) to receive blood transfusions (57.5%) than those in group 1 (32.4%).@*CONCLUSION@#Our study indicates patients with delayed time to surgery have higher chance to receive blood transfusions, but no significant difference in postoperative complications (SI, OSI, WD, or DVT) between the two groups.

Introducción: El cierre de cuero cabelludo en neurocirugías supratentoriales mediante sutura intradérmica es una técnica poco difundida en la actualidad. En contraste, es común que se efectúen suturas de alta tensión con el fin de evitar dehiscencias, fístula de líquido cefalorraquídeo (LCR) y sangrado durante el período posquirúrgico, pero que no tienen buen resultado estético. Objetivo: Comparar las complicaciones relacionadas al cierre de cuero cabelludo que se presentaron en neurocirugías supratentoriales en un período de 19 meses, para determinar si utilizar un cierre de menor tensión y con mejor resultado estético, es igual de seguro que las técnicas de cierre habituales. Materiales y Métodos: Se incluyeron 84 casos de neurocirugías supratentoriales electivas. En 43 casos (control) se realizó el cierre mediante sutura continua tipo surget y en 41 casos (experimental) el cierre fue mediante sutura intradérmica. Resultados: Se presentaron 2 casos de infecciones, 1 en cada grupo (p= 0,97) y 1 caso de sangrado en el grupo control (p= 0,32). No se presentaron dehiscencias ni casos de fístula de LCR. Conclusiones: El cierre de cuero cabelludo mediante sutura intradérmica fue un método seguro que no generó una mayor incidencia de complicaciones y logró un mejor resultado estético a corto y largo plazo.
Background: Scalp closure by means of intradermal suture in patients who underwent supratentorial neurosurgeries is currently an uncommon technique. In contrast, it is usual to perform high tension sutures to avoid skin dehiscence, cerebrospinal fluid leak (CSF) and postoperative bleeding; however it usually results in unsatisfactory aesthetic results. Aim: Comparing complications, over a two year period, related to scalp closure occurred in supratentorial neurosurgeries. The goal is to establish if the intradermal suture is as safe as the current high tension closure technique.Materials and Methods: Eighty-four patients were included. In forty-three cases (control) continuous high tension suture (surget) was performed. The other forty-one cases (experimental) underwent intradermal suture. Results: Two infection cases occurred, one from each group (p= 0, 97). There was one case of bleeding that took place in the control group (p= 0,32). Neither dehiscence nor CSF leak occurred in any of the trial cases.Conclusions: Intradermal suture performed for scalp closure was as safe as surget in terms of complications occurrence and obtained better cosmetic results in the short and long term.
