Postoperative Wound Infection Rates Research Articles

The effect of delayed-release antibiotics on the rate of postoperative wound infection for implanted neuromodulatory devices.

Implanted neuromodulatory devices are important for the surgical management of pain, epilepsy, movement disorders, and spasticity. These devices are surgically implanted, but many must be periodically explanted and replaced as batteries deplete or devices fail. Replacement surgery risks further infections that require device explantation, incur large financial costs, and reduce patient quality of life. To reduce infection rates, a single surgeon began using vancomycin-impregnated absorbable calcium sulfate delayed-response beads with neuromodulatory device and intrathecal pump primary implantations and replacements. The infection rates when using vancomycin-impregnated beads were compared with previously published rates from the same surgeon. Patients were identified who underwent primary placement or replacement of an implanted neuromodulatory control device (pumps, generators, and stimulators) with vancomycin-impregnated absorbable calcium sulfate beads between 2019 and 2022. Control data were obtained from patients who underwent surgery prior to the start of using antibiotic beads (2016-2019). Postoperative infection status as well as de-identified demographic and clinical data were extracted from electronic health records. Patients were stratified by use of antibiotic beads, device type, and whether they had an infection within 1 year requiring explantation. Statistical comparisons were made using independent t-tests, Fisher's exact test, and the chi-square test, with α set at 0.05. Effect size was calculated using Cohen's h statistic. A total of 665 surgeries were included for 611 patients who received antibiotic beads with device implantation, compared to 393 surgeries for 379 patients without antibiotic beads. The postoperative wound infection rate was 1.5% (n = 10 patients) versus 3.6% (n = 14 patients) for antibiotic beads versus controls (p = 0.03). When stratified by device type, a significant reduction in infection rate was found only with deep brain stimulation (DBS) generators (3.4% for controls vs 0.2% for beads, p = 0.002), which corresponds to a small to medium effect size (h = 0.27). The use of vancomycin-impregnated absorbable calcium sulfate beads was associated with a reduced rate of postoperative infection rates with implantable devices, and specifically for DBS primary implantation and replacement surgeries.

047. Comparison of Single-Port and Three-Port Laparoscopic Appendicitis Techniques in Adult Appendicitis

Background: Laparoscopic appendectomy (LA) become the standard for treatment of appendicitis in many countries, offering benefits such as quick recovery, fewer postoperative complications, and good cosmetic outcomes. Minimally invasive surgical techniques like single-port laparoscopic appendectomy (SPLA) are increasingly performed for better cosmetic results. However, the outcomes and safety of this technique compared to conventional three-port laparoscopic appendectomy (CTLA) still debated among experts. To compare the outcomes between SPLA and CTLA in adult appendicitis, focusing on outcomes such as postoperative wound infection rates, operating time, and surgical costs. Methods: Comprehensive search through various online databases such as PubMed, ScienceDirect, Scopus, Cochrane, and Google Scholar from 2014-2024 was performed. This research was conducted following the PRISMA guidelines. Oxford Evidence-Based Medicine criteria to assess the quality of the paper. Articles that fulfilled the eligibility criteria were retrieved and extracted for study characteristics and outcomes. Results: Four studies met the inclusion criteria, 434 patients undergoing either SPLA or CTLA procedures. There were no significant differences in complication rates such as wound infection and ileus between the two techniques. Conclusion: The SPLA technique is safe and reliable option with advantages in better cosmetic outcomes and shorter hospital stay duration, despite requiring longer operating time compared to CTLA.

Factors Associated with Symptom Recurrence Following Operative Treatment of Interdigital Neuroma

Category: Midfoot/Forefoot; Trauma Introduction/Purpose: Interdigital Neuroma (IN) is a benign enlargement of tissue surrounding the common plantar digital nerve. Traditionally, neurectomy has been performed as the standard surgical treatment for IN. However, recent attention has been given to less invasive surgical decompression by intermetatarsal ligament (IML) release with neurolysis. This study aims to compare the outcomes of IML release with neurolysis to traditional interdigital neurectomy. Methods: A retrospective chart review was conducted on 350 consecutive patients who underwent surgical treatment for IN. Patients who satisfied our inclusion and exclusion criteria were categorized into two groups based on the surgical treatment received: IML release with neurolysis or interdigital neurectomy. Inclusion criteria were patients older than 18 years with symptomatic IN, having an indication for surgical treatment following at least three months of unsuccessful conservative treatment, and at least 12 months of postoperative follow-up. Patients with concurrent procedures at the time of surgery, multiple affected web spaces, trauma to the affected forefoot, or asymptomatic IN without clear indications for surgical treatment were excluded from the study. Evaluated outcomes included recurrence of symptoms, rate of revision surgery, and postoperative wound infection. Results: Out of the 350 patients screened, 127 fulfilled the inclusion and exclusion criteria. Forty (32%) patients experienced recurrence of symptoms within a 12-month follow-up period with an overall mean time-to-recurrence of 3.96 +/- 3.15 months. Patients who underwent IML release with neurolysis had a significantly higher recurrence rate (48%) and mean time-to-recurrence of 4.61 +/- 3.22 months compared to those who underwent interdigital neurectomy (24%) with a mean time-to-recurrence of 3.47 +/- 3.08 months (P< 0.01). The rate of postoperative wound infection was similar between the two groups. The rate of revision surgery among those with symptom recurrence in the IML release group (16%) and neurectomy group (4%) was not statistically significant between both groups (P=0.49). Conclusion: IML release with neurolysis appears to have a higher risk of symptom recurrence compared to interdigital neurectomy. However, patients who did experience symptom recurrence in either operative group had similar rates of revision surgery, which may be due to mild recurrent symptoms in the IML release group that did not warrant revision surgery in these patients. No patient-specific factors were identified as being associated with symptom recurrence. Future studies should consider objective symptom recurrence severity and patient satisfaction.

WP1.9 - An audit of prophylactic antibiotic use in elective inguinal hernia repair

Abstract Aims National guidance states that antibiotic prophylaxis is not indicated in low-risk patients undergoing inguinal hernia repairs and that high-risk patients require a single dose. This audit aimed to compare the use of prophylactic antibiotics by general surgeons in a district general hospital performing elective inguinal hernia repair, to the current national guidance. The rate of post-operative wound infection was also recorded. Method All patients who underwent an elective inguinal hernia repair in the six months between January and June 2023, were identified retrospectively via the hospital database. Data was collected via the electronic patient record system on whether patients were prescribed antibiotics prophylactically at the time of surgery. Data was also collected on patient demographics including sex, age, BMI and rate of post-operative wound infection. Results The patient cohort was 94% male with an average age of 64. 94.79% of repairs were open. 53.33% of patients received antibiotics in line with national guidelines. Overall, 50.00% of patients in this audit had prophylactic antibiotics. The rate of post-operative wound infection was 1.04%, with 0% in patients who received prophylactic antibiotics and 2.08% in those who did not, which is not a statistically significant difference (P = 0.175). Conclusions Current evidence for antibiotic use is weak and therefore auditing local practice is essential in antibiotic stewardship. This audit is limited by the reliance on accurate record keeping, with regards to antibiotic prescribing and documentation of post-operative wound infections. Furthermore, patients may have had post-operative wound infections managed in the community setting.

WP1.8 - No, we can’t repair your hernia: An audit to assess pre-operative optimisation for umbilical hernia repair

Abstract Aims The European Hernia Association recently published guidelines which clearly outline the importance of pre-operative optimisation for those undergoing elective umbilical/epigastric hernias. The main factors of importance are: smoking cessation and BMI <35. This audit aimed to identify if we are adequately optimising our patients. Methods We retrospectively evaluated all elective umbilical hernia repairs from 1st January 2022- 31st December 2022 within a district general hospital setting. Clinic letters and pre-operative records were used to ascertain smoking status, BMI and diabetic control (HbA1c). Results 60 umbilical hernias were performed in our district general hospital setting from 1st January 2022- 31st December 2022. Of these patients, 12% (N=7) were known smokers and 13% (N=8) had a BMI of over 35 documented. Additionally, only in 15 cases, was there clear documentation of the patient smoking status. Out of these patients, 9 were subsequently found to be non-smokers and 6 remained smokers despite being given smoking cessation advice. Furthermore, in 10% (N=6) of these cases, there was poor diabetic control (HbA1c > 48), which was not addressed in clinic pre-operatively. Conclusion Patient factors such as smoking, obesity and diabetic control have been shown to significantly increase the rate of post-operative wound infections and complications. Patients are not being adequately optimised for elective procedures which puts them at increased risk of complications and increases the burden on limited NHS resources.

Comparison of Postoperative Wound Infection in Controlled Diabetic and Non-Diabetic Patients in Elective Operations

Background: Diabetes mellitus (DM) is a systemic disease that alters the metabolism of blood sugar. Poorly controlled diabetes or hyperglycaemia is associated with an array of micro-vascular, macro-vascular, and neuropathic complications. There is a widely held belief that infections are usually more frequent and severe in diabetic patients. Diabetes prevalence is increasing in the developed & developing countries, and the appropriate management of patients with diabetes has become increasingly important for the prevention of hospital-acquired infections. Postoperative wound infection continues to be a major source of morbidity and mortality in developing countries despite recent advances in aseptic techniques. There is little information regarding postoperative wound infection in controlled diabetic patients undergoing elective operation. Objectives: The aim of our study was to evaluate the postoperative wound infection in controlled diabetic and non-diabetic patients in elective operations. Materials & method: This cross sectional comparative study was conducted in Department of Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, during the period of October 2011 to March 2012. A total seventy three patients with controlled diabetics and seventy three non-diabetics were selected. Inclusion criteria were patients undergoing clean and cleancontaminated elective operations. Un-controlled diabetes, patient undergoing contaminated and dirty operation, patient with tuberculosis, jaundice, uraemia, having cortico-steroids /chemoradiation and operated for malignancies were excluded. After preoperative preparation specific operation was done. All patients were followed up for 30 days of post operative period for development of any postoperative wound infection. All information recorded in data collection sheet. Data was processed and analysed with the help of computer program SPSS-16 and Microsoft excel. Quantitative data expressed as mean and standard deviation and qualitative data as frequency and percentage. Result: The patients of diabetic group [31 male, 42 female; mean age, 44.5 (SD 8.2) years] and non-diabetic group [40 male, 33 female; mean age, 43.1 (SD 9.4) years] were similar in age and sex (p>0.05 each). The rate of postoperative wound infection after elective abdominal surgery was 7.5% [in controlled diabetic group was 12.3% and that of non-diabetic group was 2.7% (p<0.05)] and the patients of diabetic group were 5.0 times more likely to develop wound infection as compared to that of non-diabetic group (OR=4.992; 95% of CI=1.040–23.971) in clean and clean contaminated elective abdominal surgery. The length of postoperative hospital stay was significantly more in diabetic group than that of non-diabetic group (8.2 (SD ± 2.9) vs 6.8 (SD ± 3.2) days; p<0.01). Conclusion: Postoperative wound infection was higher in controlled diabetic patients than that of non-diabetic. These results support the consideration of diabetes as an independent risk factor for SSIs after elective surgery. Continued efforts are needed to improve surgical outcomes for diabetic patients.

Factors Associated With Symptom Recurrence After Surgical Treatment of Interdigital Neuroma: A Retrospective Chart Review of 127 Patients.

Interdigital neuroma (IN) is a benign enlargement of tissue surrounding the common plantar digital nerve. Although the standard surgical treatment of IN remains debated, recent attention has been given to less-invasive surgical decompression by intermetatarsal ligament (IML) release with neurolysis. This study aimed to compare the outcomes of IML release with neurolysis with standard interdigital neurectomy. A retrospective chart review was conducted on 350 consecutive patients who underwent surgical treatment of IN. Patients who satisfied our inclusion and exclusion criteria were categorized into two groups based on the surgical treatment received: IML release with neurolysis or interdigital neurectomy. Outcomes assessed included recurrence of symptoms, rate of revision surgery, and postoperative wound infection. Of the total sample, 40 patients (31.5%) reported recurrence of symptoms within a 12-month follow-up period. Patients who underwent IML release with neurolysis had a markedly higher recurrence rate (47.50%) than those who underwent interdigital neurectomy (24.14%). The rate of postoperative wound infection was similar between the two groups. Binary logistic regression revealed that only the surgical technique was associated with the recurrence of symptoms. Despite the higher rate of symptom recurrence in the IML release with neurolysis patient group, the rate of revision surgery in those with symptom recurrence was similar between both groups. IML release with neurolysis seems to have a higher risk of symptom recurrence than interdigital neurectomy. No patient-specific factors were identified as being associated with symptom recurrence. However, patients who did experience symptom recurrence in either surgical group had similar rates of revision surgery, which may be due to mild recurrent symptom severity in the IML release group that does not warrant revision surgery in these patients. Future studies should consider objective symptom recurrence severity and patient satisfaction. Level III.

Effect of two different surgical modalities for pelvic organ prolapse on postoperative wound infection in patients: A meta-analysis.

Sacrospinous ligament fixation (SSLF) is widely applied to the treatment of female pelvis organ prolapsed. Contradictory findings have already been reported in the comparison of sacrocolpopexy (SC) with SSLF. The objective of this study is to evaluate the efficacy of SC versus SSLF in treating pelvis organ prolapsed after operation. We conducted a meta-analysis of both operative approaches, including PubMed, Embase, and Cochrane Library. In this research, 822 articles were chosen from three databases, 201 were copied, and 10 were included. Among them, 7248 cases were operated on the prolapsed pelvis. It was found that SSLF surgery could significantly decrease the rate of postoperative wound infection after operation (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.42-0.82; p = 0.001). No statistical significance was found among the SSLF and the SC surgery for the post-operation haemorrhage of the patient (OR, 0.81; 95% CI, 0.23-2.83; p = 0.75). No statistical significance was found among the SSLF and the SC surgery for the postoperative period of the patient's operation (mean difference, -15.46; 95% CI, -52.87 to 21.94; p = 0.42). Applying SSLF surgery to treat pelvic prolapse in women may benefit from a reduction in the number of post-operative wound infections. However, SSLF had no statistical significance with respect to the amount of haemorrhage after operation or operation time.

Effects of high tibial osteotomy compared with unicondylar knee arthroplasty on the surgical site wound infection and pain in patients with medial knee osteoarthritis.

This study aims to comprehensively compare the effects of unicondylar knee arthroplasty (UKA) and high tibial osteotomy (HTO) on wound infection and pain in patients with medial knee osteoarthritis. A computerized search was conducted in Embase, PubMed, Google Scholar, China National Knowledge Infrastructure, Cochrane Library and Wanfang databases, from database inception to October 2023, for studies comparing UKA and HTO for medial knee osteoarthritis. Studies selection, data extraction and study quality evaluation were independently conducted by two researchers. Stata 17.0 software was employed for data analysis. Overall, 10 studies involving 870 patients with medial knee osteoarthritis were included. It was found that the UKA group had significantly lower wound visual analogue scale scores compared to the HTO group (SMD = -0.53, 95%CI: -0.87 to -0.20, p < 0.001). The incidence of wound infection in the UKA group was higher than in the HTO group (OR = 1.92, 95%CI: 0.65-5.69, p = 0.240), and the incidence of complications was lower (OR = 0.89, 95%CI: 0.52-1.54, p = 0.684), though these differences were not statistically significant. This study indicates that UKA is effective in alleviating postoperative wound pain in medial knee osteoarthritis. However, the rates of postoperative wound infection and complications are comparable to those of HTO. Clinicians should consider factors such as patient age and disease severity in making individualized treatment decisions.

Evaluation of Perioperative Clinical Parameters and Quality of Life in Patients Undergoing Radical Perineal or Retropubic Prostatectomy: A Prospective Randomized Study

Objective: The objective of study is to investigate the effects of radical retropubic and perineal prostatectomy methods in addition to the effect of pelvic lymph node dissection on perioperative morbidities, oncological outcomes and 1-year quality of life in patients with clinically local stage prostate cancer. Material and methods: Patients admitted to our clinic between January 2013 and March 2015 and diagnosed with clinically localized stage prostate cancer were included. A total of 103 patients were randomized into 3 groups in which 38 patients received radical perineal prostatectomy(RPP), 31 had radical retropubic prostatectomy(RRP), and 34 RRP with pelvic lymph node dissection(PLND). Age, comorbidities, preoperative Gleason scores and serum prostate-specific antigen(PSA) data as well as the surgical parameters, clinical and pathological stages, and 1-year follow-up data were recorded for each patient.“Extended prostate cancer index composite (EPIC)” and “SF-12v2™ Health Survey(Version 2.0)” questionnaires were used for overall and disease-specific quality of life at month 0, 1, 6 and 12 visits. Results: No difference was found between the groups with regard to preoperative data such as age, serum PSA levels, clinical stage, biopsy Gleason score and Charlson comorbidity index while intraoperative data for the amount of bleeding and the average amount of transfusion were significantly lower in RPP group(RPP:645cc, RRP:960cc, RRP+PLND:890cc).1-year recurrencefree survivals for RPP, RRP, and RRP+PLND groups were 9.9 months, 11.2 months and 10.2 months, respectively, with no significant difference.Overall and prostate cancer-specific quality of life was similar for all 3 groups.No additional benefit with nerve-sparing surgery was shown in any of the groups in terms of incontinence and erectile functions. Conclusion: Perineal dissection is beneficial in terms of the amount of bleeding and blood transfusion while prolonged postoperative drainage and wound infection rates are higher compared to retropubic approach.All 3 groups were similar in urinary, sexual, gastrointestinal and hormonal functions as well as the quality of life.

Scalp incision technique for decompressive hemicraniectomy: comparative systematic review and meta-analysis of the reverse question mark versus alternative retroauricular and Kempe incision techniques

Decompressive hemicraniectomy (DHC) is a critical procedure used to alleviate elevated intracranial pressure (ICP) in emergent situations. It is typically performed to create space for the swelling brain and to prevent dangerous and potentially fatal increases in ICP. DHC is indicated for pathologies ranging from MCA stroke to traumatic subarachnoid hemorrhage—essentially any cause of refractory brain swelling and elevated ICPs. Scalp incisions for opening and closing the soft tissues during DHC are crucial to achieve optimal outcomes by promoting proper wound healing and minimizing surgical site infections (SSIs). Though the reverse question mark (RQM) scalp incision has gained significant traction within neurosurgical practice, alternatives—including the retroauricular (RA) and Kempe incisions—have been proposed. As choice of technique can impact postoperative outcomes and complications, we sought to compare outcomes associated with different scalp incision techniques used during DHC. We queried three databases according to PRISMA guidelines in order to identify studies comparing outcomes between the RQM versus “alternative” scalp incision techniques for DHC. Our primary outcome of interest in the present study was postoperative wound infection rates according to scalp incision type. Secondary outcomes included estimated blood loss (EBL) and operative duration. We identified seven studies eligible for inclusion in the formal meta-analysis. The traditional RQM technique shortened operative times by 36.56 min, on average. Additionally, mean EBL was significantly lower when the RQM scalp incision was used. Postoperatively, there was no significant association between DHC incision type and mean intensive care unit (ICU) length of stay (LOS), nor was there a significant difference in predisposition to developing wound complications or infections between the RQM and retroauricular/Kempe incision cohorts. Superficial temporal artery (STA) preservation and reoperation rates were collected but could not be analyzed due to insufficient number of studies reporting these outcomes. Our meta-analysis suggests that there is no significant difference between scalp incision techniques as they relate to surgical site infection and wound complications. At present, it appears that outcomes following DHC can be improved by ensuring that the bone flap is large enough to enable sufficient cerebral expansion and decompression of the temporal lobe, the latter of which is of particular importance. Although previous studies have suggested that there are several advantages to performing alternative scalp incision techniques during DHC, the present study (which is to our knowledge the first to meta-analyze the literature on outcomes in DHC by scalp incision type) does not support these findings. As such, further investigations in the form of prospective trials with high statistical power are merited.

Effect of salpingectomyversus tubal ligation on postoperative wound infection in patients: A meta-analysis.

After several institutions recommended salpingectomy as opposed to tubal ligation, we attempted to perform meta-analysis to compare operative properties and rates of postoperative wound infections. There are no temporal or linguistic limitations to our search in PubMed, Cochrane Library and Embase. The search was carried out in September 2023. The database search identified 401 potential studies and five studies were included in the meta-analysis. Our study involved a comparison of salpingectomy with tube ligating in female patients who wanted to be sterilized. Our trial included at least one result of the wound and haemorrhage. The articles that did not qualify for inclusion or did not submit data, and those who did not answer questions were excluded. Abstracts and full-text articles were assessed independently by two authors using blinding. Conflicting decisions were settled by consensus. The Cochrane-recommended ROBINS-I instrument has been applied to evaluate the risk of bias in clinical trials and to establish the quality of inclusion. Two authors separately evaluated the risk of bias for each trial; differences were settled by consensus. There were no statistically significant differences in the rate of postoperative wound infections among those who had received salpingectomy or tubal ligation (OR, 0.46; 95% CI, 0.18-1.20 p = 0.11). In the three trials, the risk of bleeding following the ligation of the fallopian tubes was lower than that of the salpingectomy group (OR, 1.25; 95% CI, 1.21-1.30 p < 0.0001). From this information we have come to the conclusion that it is possible to give preference to tubal ligation for reduction of bleeding in suitable circumstances, and that the findings currently do not provide sufficient evidence for a reduction in the risk of postoperative wound infection.

Assessing postoperative wound infection rates in ultrasound-guided microwave ablation versus conventional surgery for varicose veins.

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.

Post-Operative Wound Infection after Treatment of Open Fracture Type II and Type IIIA by Applying Ilizarov Fixator: A Single Centre Experience in Bangladesh

Background: Treatment of open fracture type II and type IIIA is difficult problem as because there is chance of formation of infection (osteomyelitis) and ultimate nonunion of fracture. Objective: The purpose of the present study was to assess the rate of post-operative wound infection by application of Ilizarov fixator among open fracture of tibia in type II and type IIIA. Methodology: This was a non-randomized clinical trial which was conducted in the Department of Orthopedic Surgery at Ad-Din Sakina Women’s Medical College, Jashore, Bangladesh and at different private institutes in that area from January 2017 to December 2022 for a period of six years. The patients with the age group of 20 to 70 years were selected as study population. Results: A total number of 25 patients were recruited for this study. Out of 25 patients, 20 cases were male and 5 cases were female. Out of 25 patients 3 patients were diabetic and 2 patients were hypertensive. Affected side were on both side. The patients were included in this study and obtained excellent result with ilizarov procedure. Success rate was considered almost 100 present. Three patent developed minor wound infection. Conclusion: In conclusion no wound infection is found among the patients presented with open fracture of type II and type IIIA by application of Ilizarov fixator.

Impact of ileostomy on postoperative wound complications in patients after laparoscopic rectal cancer surgery: A meta-analysis.

To prevent anastomotic leakage and other postoperative complications after laparoscopic rectal cancer surgery, a protective ileostomy is often used. However, the necessity of performing ileostomy after laparoscopic rectal cancer remains controversial. The aim of this meta-analysis was to assess the benefit of ileostomy on wound infection after laparoscopic rectal cancer. The Cochrane Library, EMBASE, Web of Science, and PubMed were used to retrieve all related documents up to September 2023. Completion of the trial literature was submitted once the eligibility and exclusion criteria were met and the literature quality assessment was evaluated. This study compared the post-operative post-operative complications of an ileostomy with that of non-ileostomy in a laparoscope. We used Reman 5.3 to analyse meta-data. Controlled studies were evaluated with ROBINS-I. The meta-analyses included 525 studies, and 5 publications were chosen to statistically analyse the data according to the classification criteria. There was no statistically significant difference in the rate of postoperative wound infections among ostomate and nonostomate (odds ratio [OR], 1.79; 95% confidence interval [CI], 0.66, 4.84; p = 0.25). In 5 trials, the incidence of anastomotic leak was increased after surgery in nonostomate patients (OR, 0.26; 95% CI, 0.12, 0.57; p = 0.0009). Two studies reported no significant difference in the length of operation time when nonstomal compared to stomal operations in patients with rectal cancer (mean difference, 0.87; 95% CI, -2.99, 4.74; p = 0.66). No significant difference was found in the rate of wound infection and operation time after operation among the two groups, but the incidence of anastomosis leak increased after operation. Protective ileostomy after laparoscopic rectal cancer was effective in reducing the risk of anastomotic leakage in patients, and we found no additional risk of infection. We cautiously conclude that protective ileostomy is active and necessary for patients with a high risk of anastomotic leakage after surgery, which needs to be further confirmed by high-quality studies with larger samples.

Effects of rapid rehabilitation nursing model on surgical site wound infection and pain of patients with ovarian cancer: A meta-analysis.

To explore the effect of rapid rehabilitation nursing model on surgical site wound infection and pain of patients with ovarian cancer. Computer searches were performed on randomised controlled trials (RCTs) of rapid rehabilitation nursing model applied to ovarian cancer patients in PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (SinoMed), VIP and Wanfang Database from the time each database was constructed to May 2023. Two researchers independently screened the literature, extracted data and completed an assessment of the quality of the literature based on the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. The database was searched to obtain 255 articles, and 22 articles were finally included, containing 966 patients in the experimental group and 954 patients in the control group, for a total of 1920 patients. The results of the meta-analysis showed that, compared with other nursing models, the use of the rapid rehabilitation nursing model significantly reduced surgical site wound infections in patients with ovarian cancer (OR = 0.30, 95% CI: 0.15-0.61, p < 0.001) and the rate of post-operative complications (OR = 0.27, 95% CI: 0.19-0.38, p < 0.001) also reduced the patients' post-operative wound pain (MD = -0.70, 95% CI: -0.85 to -0.55, p < 0.001). The rapid rehabilitation nursing model applied to patients with ovarian cancer surgery can effectively reduce the rate of post-operative complications and wound infections, and it can also reduce the post-operative wound pain.

Effect of segmental versus lobectomy in minimally invasive surgery on postoperative wound complications in lung cancer patients: A meta-analysis.

It is still a matter of debate whether the surgical segmentectomy and lobectomy of lung cancer are comparable in the incidence of perioperative wound complications. An extensive review of the literature through August 2023 was carried out with a critical review of four databases. Following the acceptance and elimination criteria set out in the trial, as well as a qualitative assessment of the literature, this resulted in a review of related research that compared the results of both lobectomy and partial resection in the management of lung cancer. The analysis of the data was performed with the RevMan 5.3 software, and the 95% confidence interval [CI] and odds ratio [OR] were performed with either stationary or random-effect models. It is concluded that the operation time of lobectomy is shorter than that of sectioning in the treatment of segmentectomy (mean difference [MD], -38.62; 95% CI, -41.96, -35.28; p < 0.0001). But the rate of postoperative wound infection (OR, 0.62; 95% CI, 0.18, 2.15; p = 0.45) and intraoperative blood loss (MD, 17.54; 95% CI, -4.19, 39.26; p = 0.11) were not significantly different for them. Thus, for those who have received a pulmonary carcinoma operation, different operative methods might not have an impact on the incidence of postoperative wound infections. The operative procedure appears to have a major impact on the length of the operation in patients.

THE ROLE OF PROPHYLACTIC ANTIBIOTICS IN ZONE II AND ZONE V ACUTE FLEXOR TENDON INJURIES

Our study sought to establish the necessity of prolonged pre-operative antibiotic prophylaxis in patients presenting with zone II and zone V acute flexor tendon injuries (FTI). We hypothesized that a single dose of prophylactic antibiotic was adequate in prevention of post-operative wound infection in acute zone II and V FTI.This was a prospective study of 116 patients who presented with zone II and zone V acute FTI. The study included patients who were 18 years and older. Those with macroscopic contamination, immunocompromised, open fractures, bite injuries, and crush injuries were excluded. Patients were randomised into a group receiving a single dose of prophylactic antibiotic and another group receiving a continuous 8 hourly antibiotic doses until the day of surgery. Each group was subdivided into occupational and non-occupational injuries. Their post-operative wound outcomes were documented 10 – 14 days after surgery. The wound outcome was reported as no infection, superficial infection (treated with wound dressings), and deep infection (requiring surgical debridement).There was 0.9% rate of deep post-operative wound infections, which was a single zone V acute FTI case in a single dose prophylactic antibiotic group. There was a 7.8% superficial post-operative wound infection rate, which was mainly zone II acute FTI in both antibiotic groups. There was a strong association between zone II acute FTI and post-operative wound infection (p &lt; 0.05). There was no association between (antibiotic dosage or place of injury) with post-operative wound infection (p &gt; 0.05).There is no benefit in prescribing prolonged pre-operative antibiotic in patients with acute, simple lacerations to zone II and zone V FTI if there is no macroscopic wound contamination.

Ultrasound in paediatric surgery: A meta-analysis review of its influence on postoperative wound healing and infection rates.

Ultrasound (US) has traditionally been recognised for its imaging capabilities, but its emerging role as a therapeutic modality in postoperative wound management, especially in paediatric care, has garnered significant attention. This meta-analysis aimed to evaluate the influence of US on postoperative wound healing and infection rates in paediatric patients. From an initial pool of 1236 articles, seven were deemed suitable for inclusion. Postoperative wound healing was assessed using the Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scale. Notably, there was a significant difference in wound healing patterns between the US-treated and control groups (I2 = 94%, standardized mean difference [SMD]: -4.60, 95% confidence intervals [CIs]: -6.32 to -2.88, p < 0.01), as illustrated in Figure 4. Additionally, a marked difference in wound infection rates was observed between the groups (I2 = 93%, SMD: -5.86, 95% CIs: -9.04 to -2.68, p < 0.01), as portrayed in Figure 5. The findings underscore the potential benefits of US in enhancing postoperative wound healing and reducing infection rates in paediatric surgical settings. However, the application of US should be judicious, considering the nuances of individual patient needs and clinical contexts.

Effects of laparoscopic splenectomy on surgical site wound infection in patients with spleen rupture: A meta-analysis.

A meta-analysis was performed to compare the effects of laparoscopic splenectomy (LS) and open splenectomy (OS) for splenic rupture on postoperative surgical site wound infections and postoperative complications. A comprehensive computerised search was conducted for studies comparing LS with OS for the treatment of splenic rupture in the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases, with the search including studies published in any language between the creation of the databases and August 2023. Two researchers independently screened the literature and extracted the data. Literature quality was assessed using the Newcastle-Ottawa Scale, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Twenty-two studies involving 1545 patients were included. LS was superior to OS in the following aspects: reduced risk of postoperative surgical site wound infection (OR = 0.19, 95% CI: 0.11-0.34, p = 0.000), shortened hospital stay (standardised mean difference = -1.73, 95% CI: -2.05 to -1.40, p = 0.000), and reduced postoperative complication rate (OR = 0.22, 95% CI: 0.16-0.31, p = 0.000). Compared with OS, LS has a lower rate of postoperative wound infection, shorter hospital stay, and reduced rate of postoperative complications. LS is safe and effective for the treatment of splenic rupture and can be promoted clinically.
