Retrospective Study to Compare the Effectiveness of Minimally Invasive Microscopic Unilateral Laminotomy with Microscopic Bilateral Laminotomy for Bilateral Decompression in the Early Postoperative Period in 142 Patients with Single-Level Lumbar Spinal Stenosis.

BACKGROUND We aimed to compare the effectiveness of microscopic unilateral laminotomy for bilateral decompression (ULBD) and microscopic bilateral laminotomy for bilateral decompression (BLBD) in the early postoperative period among patients with single-level lumbar spinal stenosis (LSS). MATERIAL AND METHODS A retrospective cohort study was conducted on patients with LSS who underwent ULBD or BLBD between January 2020 and December 2023, including 94 patients who underwent ULBD and 58 who underwent BLBD. Patient demographics, comorbidities, smoking status, and data related to LSS were reviewed. Preoperative and postoperative assessments on day 10 included back pain visual analog scale (VAS), walking distance, and Odom criteria. Disability was evaluated using the self-assessment Oswestry Disability Index (ODI) preoperatively and on day 30. Additionally, wound infection, postoperative modified MacNab criteria, and pain (back, leg, and hip) were recorded. RESULTS Age and sex were similar in the 2 groups. Both surgeries significantly reduced low back pain, increased walking distance, and improved Odom category on day 10, compared with baseline (P<0.001 for all). A significant decrease in 30-day ODI, compared with baseline, was observed in both groups (P<0.001 for both). The ULBD group had a significantly higher percentage of patients with wound infection (P=0.014); however, the ODI score among ULBD recipients was significantly lower (better) on day 30 (P=0.047). CONCLUSIONS ULBD may represent a less invasive, more effective, and safer surgical alternative than BLBD and classical laminectomy in patients with single-level LSS, but precautions are essential concerning wound infection.

Treatment of wound infections linked to neurosurgical implants.

As neurosurgery has advanced technologically, more and more neurosurgical implants are being employed on an aging patient population with several comorbidities. As a result, there is a steady increase in the frequency of infections linked to neurosurgical implants, which causes serious morbidity and mortality as well as abnormalities of the skull and inadequate brain protection. We discuss infections linked to internal and external ventricular and lumbar cerebrospinal fluid drainages, neurostimulators, craniotomies, and cranioplasty in this article. Biofilms, which are challenging to remove, are involved in all implant-associated illnesses. It takes a small quantity of microorganisms to create a biofilm on the implant surface. Skin flora bacteria are implicated in the majority of illnesses. Microorganisms that cause disruptions in wound healing make their way to the implant either during or right after surgery. In about two thirds of patients, implant-associated infections manifest early (within the first month after surgery), whereas the remaining infections present later as a result of low-grade infections or by direct extension from adjacent infections (per continuitatem) to the implants due to soft tissue damage. Except for ventriculo-atrial cerebrospinal fluid shunts, neurosurgical implants are rarely infected by the haematogenous route. This research examines established and clinically validated principles that are applicable to a range of surgical specialties using implants to treat biofilm-associated infections in orthopaedic and trauma cases. Nevertheless, there is little evidence and no evaluation in sizable patient populations to support the success of this extrapolation to neurosurgical patients. An optimal microbiological diagnostic, which includes sonicating removed implants and extending culture incubation times, is necessary for a positive result. Additionally, a strategy combining surgical and antibiotic therapy is needed. Surgical procedures involve a suitable debridement along with implant replacement or exchange, contingent on the biofilm's age and the state of the soft tissue. A protracted biofilm-active therapy is a component of antimicrobial treatment, usually lasting 4-12 weeks. This idea is appealing because it allows implants to be changed or kept in place for a single surgical procedure in a subset of patients. This not only enhances quality of life but also lowers morbidity because each additional neurosurgical procedure increases the risk of secondary complications like intracerebral bleeding or ischemia.

A meta-analysis evaluating wound infections and other complications following distal versus complete gastrectomy for gastric cancer.

A meta-analysis investigation was carried out to measure the wound infections (WIs) and other postoperative problems (PPs) of distal gastrectomy (DG) compared with total gastrectomy (TG) for gastric cancer (GC). A comprehensive literature investigation till February 2023 was used and 1247 interrelated investigations were reviewed. The 12 chosen investigations enclosed 2896 individuals with GC in the chosen investigations' starting point, 1375 of them were TG, and 1521 were DG. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the WIs and other PPs of DG compared with TG for GC by the dichotomous approaches and a fixed or random model. TG had significantly higher overall PP (OR, 1.58; 95% CI, 1.15-2.18, p = 0.005), WIs (OR, 1.69; 95% CI, 1.07-2.67, p = 0.02), peritoneal abscess (PA) (OR, 2.99; 95% CI, 1.67-5.36, p < 0.001), anastomotic leakage (AL) (OR, 1.90; 95% CI, 1.21-2.97, p = 0.005) and death (OR, 2.26; 95% CI, 1.17-4.37, p = 0.02) compared to those with DG in individuals with GC. TG had significantly higher overall PP, WIs, PA, AL and death compared to those with DG in individuals with GC. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

The impact of sarcobesity on incisional hernia after laparoscopic colorectal cancer surgery.

PURPOSE: Incisional hernia is a common complication after abdominal surgery, especially in obese patients. The aim of the present study was to evaluate the relationship between sarcobesity and incisional hernia development after laparoscopic colorectal cancer surgery. METHODS: In total, 262 patients who underwent laparoscopic colorectal cancer surgery were included in the present study. Univariate and multivariate analyses were performed to evaluate the independent risk factors for the development of incisional hernia. We then performed subgroup analyses to assess the impact of visceral obesity according to clinical variables on the development of incisional hernia in laparoscopic surgery for colorectal cancer surgery. RESULTS: Forty-four patients (16.8%) developed incisional hernias after laparoscopic colorectal cancer surgery. In the univariate analysis, the development of incisional hernia was significantly associated with female sex (P = 0.046), subcutaneous obesity (P = 0.002), visceral obesity (P = 0.002), sarcobesity (P < 0.001), and wound infection (P < 0.001). In the multivariate analysis, sarcobesity (P < 0.001) and wound infection (P < 0.001) were independent predictors of incisional hernia. In subgroup analysis, the odds ratio of visceral obesity was the highest (13.1; 95% confidence interval [CI], 4.51-37.8, P < 0.001) in the subgroup of sarcopenia. CONCLUSION: Sarcobesity may be a strong predictor of the development of incisional hernia after laparoscopic surgery for colorectal cancer, suggesting the importance of body composition in the development of incisional hernia.

Hemithyroidectomy, does the indication influence the outcome?

PURPOSE: Hemithyroidectomies are mainly performed for two indications, either therapeutically to relieve compression symptoms or diagnostically for suspicious nodule(s). In case of the latter, one could consider the approach to be rather extensive since the majority of patients have no symptoms and will have benign disease. The aim of this study is to investigate the complication rates of diagnostic hemithyroidectomy and to compare it with the complication rates of compressive symptoms hemithyroidectomy. METHODS: Data from patients who had undergone hemithyroidectomy either for compression symptoms or for excluding malignancy were extracted from a well-established Scandinavian quality register (SQRTPA). The following complications were analyzed: bleedings, wound infections, and paresis of the recurrent laryngeal nerve (RLN). Risk factors for these complications were examined by univariable and multivariable logistic regression. RESULTS: A total of 9677 patients were included, 3871 (40%) underwent surgery to exclude malignancy and 5806 (60%) due to compression symptoms. In the multivariable analysis, the totally excised thyroid weight was an independent risk factor for bleeding. Permanent (6-12 months after the operation) RLN paresis were less common in the excluding malignancy group (p = 0.03). CONCLUSION: A range of factors interfere and contribute to bleeding, wound infections, and RLN paresis after hemithyroidectomy. In this observational study based on a Scandinavian quality register, the indication "excluding malignancy" for hemithyroidectomy is associated with less permanent RLN paresis than the indication "compression symptoms." Thus, patients undergoing diagnostic hemithyroidectomy can be reassured that this procedure is a safe surgical procedure and does not entail an unjustified risk.

Incidences, causes and risk factors of unplanned reoperation within 30 days of craniovertebral junction surgery: a single-center experience.

PURPOSE: To investigate the incidences, causes, and risk factors for unplanned reoperation within 30 days of craniovertebral junction (CVJ) surgery. METHODS: From January 2002 to December 2018, a retrospective analysis of patients who underwent CVJ surgery at our institution was conducted. The demographics, history of the disease, medical diagnosis, approach and type of operation, surgery duration, blood loss, and complications were recorded. Patients were divided into the no-reoperation group and the unplanned reoperations group. Comparison between two groups in noted parameters was analyzed to identify the prevalence and risk factors of unplanned revision and a binary logistic regression was performed to confirm the risk factors. RESULTS: Of 2149 patients included, 34(1.58%) required unplanned reoperation after the initial surgery. The causes for unplanned reoperation contained wound infection, neurologic deficit, improper screw placement, internal fixation loosens, dysphagia, cerebrospinal fluid leakage, and posterior fossa epidural hematomas. No statistical difference was found in demographics between two groups (P > 0.05). The incidence of reoperation of OCF was significantly higher than that of posterior C1-2 fusion (P = 0.002). In terms of diagnosis, the reoperation rate of CVJ tumor patients was significantly higher than that of malformation patients, degenerative disease patients, trauma patients, and other patients (P = 0.043). The binary logistic regression confirmed that different disease, fusion segment (posterior) and surgery time were independent risk factors. CONCLUSIONS: The unplanned reoperation rate of CVJ surgery was 1.58% and the major causes were implant-related failures and wound infection. Patients with posterior occipitocervical fusion or diagnosed with CVJ tumors had an increased risk of unplanned reoperation.

Incidence of complications associated with cervical spine surgery and post-operative physical therapy and implications for timing of initiation of post-operative physical therapy: a retrospective database study.

PURPOSE: To describe the incidence of complications associated with cervical spine surgery and post-operative physical therapy (PT), and to identify if the timing of initiation of post-operative PT impacts the incidence rates. METHODS: MOrtho PearlDiver database was queried using billing codes to identify patients who had undergone Anterior Cervical Discectomy and Fusion (ACDF), Posterior Cervical Fusion (PCF), or Cervical Foraminotomy and post-operative PT from 2010-2019. For each surgical procedure, patients were divided into three 12-week increments for post-operative PT (starting at post-operative weeks 2, 8, 12) and then matched based upon age, gender, and Charlson Comorbidity Index score. Each group was queried to determine complication rates and chi-square analysis with adjusted odds ratios, 95% confidence intervals, and p-values were used. RESULTS: Following matching, 3,609 patients who underwent cervical spine surgery at one or more levels and had post-operative PT (ACDF:1784, PCF:1593, and cervical foraminotomy:232). The most frequent complications were new onset cervicalgia (2-14 weeks, 8-20 weeks, 12-24 weeks): ACDF (15.0%, 14.0%, 13.0%), PCF (18.8%, 18.0%, 19.9%), cervical foraminotomy (16.8%, 16.4%, 19.4%); revision: ADCF (7.9%, 8.2%, 7.4%), PCF (9.3%, 10.6%, 10.2%), cervical foraminotomy (11.6%, 10.8% and 13.4%); wound infection: ACDF (3.3%, 3.4%, 3.1%), PCF (8.3%, 8.0%,7.7%), cervical foraminotomy (5.2%, 6.5%, < 4.7%). None of the comparisons were statistically significant. CONCLUSION: The most common post-operative complications included new onset cervicalgia, revision and wound infection. Complications rates were not impacted by the timing of initiation of PT whether at 2, 8, or 12 weeks post-operatively.

Negative pressure sealing drainage with antibiotic bone cement for the treatment of skin and soft tissue defects in the older population with bone exposure.

OBJECTIVE: To observe the clinical efficacy of vacuum sealing drainage (VSD) combined with antibiotic bone cement in the treatment of skin and soft tissue defects of the extremities with bone exposure in the older population. METHOD: From January 2016 to December 2018, VSD combined with antibiotic bone cement was used to treat 12 older patients with skin and soft tissue defects of the extremities and bone exposure. The study cohort consisted of eight male patients and four female patients aged between 60-95 years, with a median of 75 years. The injury sites included four cases of hand, one case of calf, one case of ankle and six cases of back of foot. The area of skin and soft tissue defects ranged from 2.7×4.1cm to 4.8×4.9cm. There were four infected wounds and eight contaminated wounds. The time from injury to operation was 1.5-6 hours, with a median of 5 hours. In the first stage of the treatment, the wound was covered with a VSD dressing; in the second stage the VSD dressing was replaced with antibiotic bone cement after infection control; and in the third stage, the bone cement was removed and the wound was transplanted with medium-thickness skin grafts according to the wound condition. The skin graft survival and wound healing were assessed. RESULTS: After the first-stage debridement, three of the 12 patients had wound infections, including two cases of meticillin-resistant Staphylococcus aureus infection and one case of Pseudomonas aeruginosa infection. After the bone cement was removed in the third stage, five of the 12 patients underwent free medium-thickness skin grafting on the wound surface (the area of the autologous skin ranged from 2.9×4.3cm to 4.9×5.0cm), and seven patients continued to change dressing routinely. All patients were followed up for 4-15 months, with a median of 10 months. All skin grafts survived and the wounds healed. The healing time was 48-115 days, with a median of 72 days. At the last follow-up, the skin of the affected limb was slightly darker than the surrounding skin, and the appearance was smooth, without obvious scar tissue formation. CONCLUSION: VSD combined with antibiotic bone cement in the treatment of skin and soft tissue defects of the extremities with bone exposure in the older population has a high survival rate of skin grafts and good wound healing. It is worthy of clinical application.

Mesenchymal Stem Cells and Regenerative Therapy with Bilateral Gracilis Flaps for Perineal Reconstruction of a Wound Infection in the Setting of Anal Squamous Cell Carcinoma.

ABSTRACT: Many patients are affected by HIV/AIDS, and these conditions are highly prevalent worldwide. Patients with HIV/AIDS can experience debilitating wound infections that often require flap reconstruction and become challenging for surgeons to treat. In the past 5 years, mesenchymal stem cells have been tested and used as regenerative therapy to promote the growth of tissues throughout the body because of their ability to successfully promote cellular mitogenesis. To the authors' knowledge, the use of mesenchymal stem cell grafting following necrosis of a myocutaneous gracilis flap (as part of perineal wound reconstruction) has never been reported in the literature.In addition, the use of mesenchymal stem cells and regenerative medicine combined in the setting of squamous cell carcinoma of the anus with prior radiation (along with comorbid AIDS) has not been previously documented.In this report, the authors outline the case of a 60-year-old patient who had a recipient bed (perineum) complication from prior radiation therapy. Complicating the clinical picture, the patient also developed a Pseudomonal organ space infection of the pelvis leading to the failure of a vertical rectus abdominis myocutaneous flap and myocutaneous gracilis flaps. As a result, the patient underwent serial operative debridements for source control, with the application of mesenchymal stem cells, fetal bovine dermis, porcine urinary bladder xenograft, and other regenerative medicine products, achieving a highly successful clinical outcome. A procedural description for future use and replication of this method is provided.

Effect of minimally invasive versus open surgery in hepatectomy on postoperative wound complications in patients with hepatocellular carcinoma: A meta-analysis.

In a meta-analysis, we assessed the impact of different surgical approaches on the outcome of hepatectomy with hepatocellular carcinoma. Four databases, including PubMed, Embase, Cochrane Library, and the Web of Science, have been critically reviewed through the full literature through June 2023. Eleven related trials were examined once they had met the trial's classification and exclusion criteria, as well as the assessment of the quality. A random effects approach was applied to analysis of operative organ infections, and a fixed-effect model was applied to determine the 95% CI and OR. Analysis of the data was done with RevMan 5.3. Our findings indicated that patients undergoing minimally invasive liver cancer surgery had significantly lower risks of surgical organ infection (OR, 0.35; 95% CI, 0.16-0.77; p = 0.009) and wound infection (OR, 0.19; 95% CI, 0.13-0.28; p < 0.001) compared to those undergoing open surgery. There was no heterogeneity observed between the two groups (I2 = 0) in wound infection. Nevertheless, because of the limited number of randomised controlled trials in this meta-analysis, care should be taken and carefully considered in the treatment of these values. Further high-quality studies involving a large number of samples are needed to validate and reinforce the results.

Effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer: A meta-analysis.

We performed a meta-analysis to evaluate the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer. A systematic literature search up to July 2022 was performed and 10 231 subjects with cervical cancer at the baseline of the studies; 4307 of them were using the minimally invasive surgery, and 5924 were using laparotomy. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer using the dichotomous methods with a random or fixed-effect model. The minimally invasive surgery had significantly lower wound infection (OR, 0.20; 95% CI, 0.13-0.30, P < .001), and postoperative complications (OR, 0.48; 95% CI, 0.37-0.64, P < .001) in subjects with cervical cancer compared laparotomy. However, minimally invasive surgery compared with laparotomy in subjects with cervical cancer had no significant difference in intraoperative complications (OR, 1.04; 95% CI, 0.80-1.36, P = 0.76). The minimally invasive surgery had significantly lower wound infection, and postoperative complications however, had no significant difference in intraoperative complications in subjects with cervical cancer compared with laparotomy. The analysis of outcomes should be with caution because of the low sample size of 22 out of 41 studies in the meta-analysis and a low number of studies in certain comparisons.

Minimizing Antibiotic Use in Urethral Reconstruction.

PURPOSE: There are no established guidelines regarding management of antibiotics for patients specifically undergoing urethral reconstruction. Our aim was to minimize antibiotic use by following a standardized protocol in the pre-, peri- and postoperative setting, and adhere to American Urological Association antibiotic guidelines. We hypothesized that prolonged suppressive antibiotics post-urethroplasty does not prevent urinary tract infection and/or wound infection rates. MATERIALS AND METHODS: We prospectively treated 900 patients undergoing urethroplasty or perineal urethrostomy at 11 centers over 2 years. The first-year cohort A received prolonged postoperative antibiotics. Year 2, cohort B, did not receive prolonged antibiotics. A standardized protocol following the American Urological Association guidelines for perioperative antibiotics was used. The 30-day postoperative infectious complications were determined. We used chi-square analysis to compare the cohorts, and multivariate logistic regression to identify risk factors. RESULTS: The mean age of participants in both cohorts was 49.7 years old and the average stricture length was 4.09 cm. Overall, the rate of postoperative urinary tract infection and wound infection within 30 days was 5.1% (6.7% in phase 1 vs 3.9% in phase 2, p=0.064) and 3.9% (4.1% in phase 1 vs 3.7% in phase 2, p=0.772), respectively. Multivariate logistic regression analysis of patient characteristics and operative factors did not reveal any factors predictive of postoperative infections. CONCLUSIONS: The use of a standardized protocol minimized antibiotic use and demonstrated no benefit to prolonged antibiotic use. There were no identifiable risk factors when considering surgical characteristics. Given the concern of antibiotic over-prescription, we do not recommend prolonged antibiotic use after urethral reconstruction.

Scoring Model to Predict Major Amputation in Patients With Chronic Limb-Threatening Ischemia at Wound, Ischemia, and Foot Infection Clinical Stage 4 After Endovascular Therapy.

PURPOSE: We investigated the predictors of major amputation (MA) at 1 year and prepared a scoring model to stratify the clinical outcomes of chronic limb-threatening ischemia (CLTI) patients at wound, ischemia, and foot infection (WIfI) clinical stage 4 after endovascular therapy (EVT). MATERIALS AND METHODS: This study was a retrospective, observational study performed at a single center. A total of 353 CLTI patients (390 limbs) were treated with EVT between April 2007 and December 2016. Among these, limbs at WIfI clinical stages 1, 2, and 3 were excluded, and 194 limbs at WIfI clinical stage 4 (49.7%) were enrolled. The primary endpoint was major amputation (MA) free rate at 1 year. Predictors of MA at 1 year was evaluated by Cox proportional hazard analysis. RESULTS: At 1 year, the incidence of MA was 18.0% (35 limbs). Cox proportional hazard analysis revealed that hemodialysis (hazard ratio [HR] 2.63; 95% confidence interval [CI], 1.24-5.58; p=0.012), fI3 (HR 2.54; 95% CI, 1.28-5.06; p=0.008), toe wounds (HR 0.29; 95% CI, 0.094-0.88; p=0.029), and visible blood flow to the wound (HR 0.43; 95% CI, 0.21-0.89; p=0.023) were associated with MA. We assigned 1 point for positive predictors of MA, hemodialysis, and fI3; 1 point was deducted for negative predictors of MA, toe wounds, and visible blood flow to the wound. A score of -2 or -1, was defined as the low-risk group, 0 was defined as the intermediate-risk group, and +1 or +2 were defined as the high-risk group. At 1 year, MA free rate, wound healing rate, and amputation-free survival rate were stratified according to a scoring model. MA free rate was 96.6% in low-risk, 72.4% in intermediate-risk, and 67.3% in high-risk (p<0.001); wound healing rate was 67.8% in low-risk, 27.6% in intermediate-risk, and 4.1% in high-risk (p<0.001); amputation-free survival rate was 65.3% in low-risk, 44.8% in intermediate-risk, and 18.4% in high-risk (p<0.001). CONCLUSIONS: The scoring model based on the predictors of MA stratified clinical outcomes in CLTI patients at WIfI clinical stage 4.

SdrG gene activated joint surface membrane protein PTPRJ to induce periprosthetic joint infection after total hip arthroplasty.

WHAT IS KNOWN AND OBJECTIVE: Up to now, no study focused on the role of SdrG in PJI after THA. To explore the mechanism of periprosthetic joint infection (PJI) after total hip arthroplasty (THA). METHODS: Joint fluid and blood were collected from patients with PJI after THA, aseptic loosening of the joints or bacterial infection after traumatic fractures of the extremities alone. The expression of SdrG in the 3 groups was determined by agarose gel electrophoresis. The expression of protein tyrosine phosphatase receptor J (PTPRJ) was measured by immunohistochemistry method. The platelet adhesion rate was determined by biochemical analysis. The content of D-dimer, CRP and ESR in blood was determined by latex agglutination method. Multiple linear correlation analysis was used to analyse the correlation between PJI and the expression of PTPRJ protein, platelet adhesion rate, D-dimer content, CRP and ESR. RESULTS AND DISCUSSION: The expression of SdrG and PTPRJ in PJI group was markedly increased compared to the other 2 groups. The platelet adhesion rate in PJI group was markedly larger compared to aseptic loosening and simple wound infection group, and the rate in simple wound infection group was larger than aseptic loosening group. The level of D-dimer, CRP and ESR in PJI group was higher than that of the other groups. The expression of PTPRJ protein, D-dimer content, CRP and ESR was all closely related to PJI, while platelet adhesion rate had no correlation with PJI. WHAT IS NEW AND CONCLUSION: SDRG gene around joint prosthesis was over-expressed, which activated joint surface membrane protein PTPRJ and then induced platelet aggregation to reduce joint function.

Primary closure versus Graham patch omentopexy in perforated peptic ulcer: A systematic review and meta-analysis.

BACKGROUND: There are different methods to repair a perforated peptic ulcer, the two most frequently used are the Graham patch omentopexy and the primary closure. Currently there is no high-level evidence to provide guidance of the optimal method of repair. The aim of this study is to compare the outcomes of the two methods so as to provide improved guidance for surgeons undertaking this repair. METHODS: A systematic review and meta-analysis was conducted including any study that compared Graham patch omentopexy with primary closure in adults. Embase, Medline, Cochrane and Google's search engine were searched. The primary outcome was breakdown of the repair resulting in bile leak and the secondary outcomes were mortality, operation time, wound infection and time to start oral intake. The meta-analysis was conducted using Review Manager Software version 5:4. Outcome data were reported as odd ratios and weighted mean differences with their 95% confidence intervals. RESULTS: Of the 229 studies identified, 6 were suitable for analysis, 4 were retrospective, one was a prospective cohort study and one was a randomized controlled trial. Meta-analysis showed no difference in occurrence of bile leak or mortality between primary closure and Graham patch omentopexy (OR 0.64; 95% (0.26-1.54) & 0.66; 95% (0.25-1.76) respectively). There was no difference in the rates of wound infection OR 0.65; 95% (0.4-1.05). The duration of the operation was shorter in the primary closure group by 5.6 min; 95% (-21 + 10.4). CONCLUSION: There was no difference in the clinical outcomes between the two modes of repair.

Laparoscopic versus open repair of congenital duodenal obstruction: a systematic review and meta-analysis.

PURPOSE: To assess the safety and efficacy of laparoscopic versus open repair of congenital duodenal obstruction (CDO), we conducted a systematic review and meta-analysis (CDO). METHODS: A literature search was conducted to identify studies that compared laparoscopic surgery (LS) and open surgery (OS) for neonates with CDO. Meta-analysis was used to pool and compare variables such as operative time, time to feeding, length of hospital stay, anastomotic leak or stricture, postoperative ileus, wound infection, and overall postoperative complications. RESULTS: Among the 1348 neonatal participants with CDO in the ten studies, 304 received LS and 1044 received OS. When compared to the OS approach, the LS approach resulted in shorter hospital stays, faster time to initial and full feeding, longer operative time, and less wound infection. However, no significant difference in secondary outcomes such as anastomotic leak or stricture, postoperative ileus, and overall postoperative complications was found between LS and OS. CONCLUSIONS: LS is a safe, feasible and effective surgical procedure for neonatal CDO when compared to OS. Compared with OS, LS has a faster time to feeding, a shorter hospital stay, and less wound infection. Furthermore, in terms of anastomotic leak or stricture, postoperative ileus, and overall postoperative complications, LS is equivalent to OS. We conclude that LS should be considered an acceptable option for CDO.

Three-stage limb salvage in tibial fracture related infection with composite bone and soft-tissue defect.

INTRODUCTION: Managing critical-sized tibial defects is one of the most complex challenges orthopedic surgeons face. This is even more problematic in the presence of infection and soft-tissue loss. The purpose of this study is to describe a comprehensive three-stage surgical protocol for the reconstruction of infected tibial injuries with combined bone defects and soft-tissue loss, and report the clinical outcomes. MATERIALS AND METHODS: A retrospective study at a specialized limb reconstruction center identified all patients with infected tibial injuries with bone and soft-tissue loss from 2010 through 2018. Thirty-one patients were included. All cases were treated using a three-stage protocol: (1) infected limb damage control; (2) soft-tissue coverage with a vascularized or local flap; (3) definitive bone reconstruction using distraction osteogenesis principles with external fixation. PRIMARY OUTCOMES: limb salvage rate and infection eradication. SECONDARY OUTCOMES: patient functional outcomes and satisfaction. RESULTS: Patients in this series of chronically infected tibias had been operated upon 3.4 times on average before starting our limb salvage protocol. The mean soft-tissue and bone defect sizes were 124 cm2 (6-600) and 5.4 cm (1-23), respectively. A free flap was performed in 67.7% (21/31) of the cases; bone transport was the selected bone-reconstructive option in 51.7% (15/31). Local flap failure rate was 30% (3/10), with 9.5% for free flaps (2/21). Limb salvage rate was 93.5% (29/31), with infection eradicated in all salvaged limbs. ASAMI bone score: 100% good/excellent. Mean VAS score was 1.0, and ASAMI functional score was good/excellent in 86% of cases. Return-to-work rate was 83%; 86% were "very satisfied" with the treatment outcome. CONCLUSION: A three-stage surgical approach to treat chronically infected tibial injuries with combined bone and soft-tissue defects yields high rates of infection eradication and successful limb salvage, with favorable functional outcomes and patient satisfaction.

Short-term post-operative complications in 207 patients with multi-level degenerative cervical myelopathy: the effect of surgical approach.

INTRODUCTION: Degenerative cervical myelopathy (DCM) is a common condition often treated by surgical decompression and fusion. The objective of this paper was to compare short-term post-operative complication rates of patients with multi-level DCM treated with decompression and fusion using either an anterior or a posterior cervical approach. MATERIAL AND METHODS: A retrospective evaluation of patients' charts, imaging studies and operative reports of patients operated for multilevel subaxial DCM from 2011 to 2016 at a single institution was performed. Patients who were operated upon for the treatment of three stenosed spinal levels or above and who underwent anterior cervical discectomy and fusion, or anterior cervical corpectomy and fusion, or posterior cervical laminectomy and fusion, were included. Short-term post-operative complications were compared between the anterior and posterior approaches. RESULTS: Overall, 207 patients were included in this study. 156 were operated via an anterior approach and 51 via a posterior approach. The mean number of treated levels was 3.4 and 4.3 for the anterior and posterior approach groups, respectively (p < 0.001). In the posterior approach group, the proportion of stenosed spinal levels within all operated levels was significantly lower than in the anterior approach group (p = 0.025). Early post-operative neurological status change was favourable for both groups. Deep wound infection rate was significantly higher in the posterior approach group (7.8% vs. none; p = 0.001). CONCLUSIONS: Posterior cervical laminectomy and fusion is significantly associated with an increased rate of deep wound infection and wound revision surgery compared to the anterior approach. We recommend the anterior approach as the valid option in treating multi-level DCM.

Management of critical-sized bone defects in the treatment of fracture-related infection: a systematic review and pooled analysis.

PURPOSE: This systematic review determined the reported treatment strategies, their individual success rates, and other outcome parameters in the management of critical-sized bone defects in fracture-related infection (FRI) patients between 1990 and 2018. METHODS: A systematic literature search on treatment and outcome of critical-sized bone defects in FRI was performed. Treatment strategies identified were, autologous cancellous grafts, autologous cancellous grafts combined with local antibiotics, the induced membrane technique, vascularized grafts, Ilizarov bone transport, and bone transport combined with local antibiotics. Outcomes were bone healing and infection eradication after primary surgical protocol and recurrence of FRI and amputations at the end of study period. RESULTS: Fifty studies were included, describing 1530 patients, the tibia was affected in 82%. Mean age was 40 years (range 6-80), with predominantly male subjects (79%). Mean duration of infection was 17 months (range 1-624) and mean follow-up 51 months (range 6-126). After initial protocolized treatment, FRI was cured in 83% (95% CI 79-87) of all cases, increasing to 94% (95% CI 92-96) at the end of each individual study. Recurrence of infection was seen in 8% (95% CI 6-11) and amputation in 3% (95% CI 2-3). Final outcomes overlapped across treatment strategies. CONCLUSION: Results should be interpreted with caution due to the retrospective and observational design of most studies, the lack of clear classification systems, incomplete data reports, potential underreporting of adverse outcomes, and heterogeneity in patient series. A consensus on classification, treatment protocols, and outcome is needed to improve reliability of future studies.

Temporary Diverting End-Colostomy in Critically Ill Children with Severe Perianal Wound Infection.

ABSTRACT: Broad and deep perianal wounds are challenging in both adult and pediatric ICUs. These wounds, if contaminated with gastrointestinal flora, can cause invasive sepsis and death, and recovery can be prolonged. Controlling the source of infection without diverting stool from the perianal region is complicated. The option of protective colostomy is not well-known among pediatric critical care specialists, but it can help patients survive extremely complicated critical care management. These authors present three critically ill children who required temporary protective colostomy for perianal wounds because of various clinical conditions. Two patients were treated for meningococcemia, and the other had a total artificial heart implantation for dilated cardiomyopathy. There was extensive and profound tissue loss in the perianal region in the patients with meningococcemia, and the patient with cardiomyopathy had a large pressure injury. Timely, transient, protective colostomy was beneficial in these cases and facilitated the recovery of the perianal wounds. Temporary diverting colostomy should be considered as early as possible to prevent fecal transmission and accelerate perianal wound healing in children unresponsive to local debridement and critical care.
