Efficacy of Hypothermic Compression Bandages in Cardiac Device Surgical Wounds: A Randomized Controlled Trial.

BACKGROUND: Pocket hematoma is the most prevalent complication with cardiac implantable electronic devices (CIEDs), especially in patients who are undergoing oral anticoagulation and/or antiplatelet therapy. OBJECTIVE: To evaluate the efficacy of hypothermic compression bandaging versus conventional compression bandaging for the prevention of surgical wound hematoma of CIEDs in patients who are undergoing chronic anticoagulant drug use and/or antiplatelet therapy. METHODS: This was a single-center randomized prospective study. The intervention group received a hypothermic compression bandage, and the control group received a conventional compression bandage. The primary endpoint was the appearance of hematoma 10 days after the intervention. RESULTS: A total of 310 patients participated in the study. The mean age of the participants was 73.77 ± 10.68 years, and 74.8% were men. In the intervention group, 5.88% (n = 18) of patients developed ecchymosis, and 1.3% (n = 4) developed mild hematoma. In the control group, 5.88% (n = 18) of patients developed ecchymosis, and 2.9% (n = 9) developed mild hematoma. No patient in either group had a severe hematoma. No significant differences were observed between the two types of dressing in any of the three degrees of hematoma. CONCLUSIONS: This study demonstrated that compression bandaging with or without hypothermic therapy effectively prevents pocket hematoma of CIEDs in patients at high risk of bleeding.

Nonhealing Surgical Wounds in a Patient with Plasminogen Deficiency Type 1 Successfully Treated with Intravenous Plasminogen: A Case Report.

ABSTRACT: Intravenous plasminogen replacement therapy for patients with plasminogen deficiency type 1 (hypoplasminogenemia) was recently approved for marketing in the US. In this case report, the authors describe a 33-year-old man with hypoplasminogenemia who developed nonhealing postsurgical wounds following trauma to his right hand despite receiving standard treatment for 4 months. The patient was enrolled in a compassionate-use protocol with intravenous plasminogen replacement therapy and experienced prompt resolution of surgical wounds. He was the first human patient to receive replacement therapy with plasminogen, human-tvmh in the US and first to demonstrate cutaneous wound healing in addition to resolution of ligneous lesions attributable to plasminogen deficiency type 1.

Predictors of Surgical Site Infection in Contaminated Abdominal Surgical Wounds: Our Experience in Irrua Specialist Teaching Hospital.

BACKGROUND: Secondary peritonitis is a common emergency surgical condition with varying aetiologies managed by surgeons all over the world. One important morbidity associated with it is postoperative surgical site infection (SSI). A better prevention strategy can be instituted if this complication in patients can be correctly predicted. The study aimed to identify factors in patients with peritonitis that have a significant bearing on the development of postoperative SSI. METHOD: A total of fifty patients operated on for peritonitis in a period of one year were studied. Factors including age, gender, comorbidities, presenting symptoms, time of presentation, time of intervention, intraoperative findings, duration of surgery, and postoperative SSI were noted. Chi-square, Fisher's exact test and Student's t-test were used to test for association where appropriate and a p-value of < 0.05 was considered statistically significant. RESULTS: Peritonitis was most commonly due to a ruptured appendix (46%) followed by perforated peptic ulcer disease (42%). The incidence of SSI was 44%. For the patients that developed SSI, the lowest rate was observed in cases of ruptured appendix (39.1%) and the highest in perforated gastric ulcer (64.3%) which was closely followed by perforated duodenal ulcer (57.1%). The association between the time of presentation and the occurrence of SSI was statistically significant (p = 0.028). CONCLUSION: The SSI rate (44%) from peritonitis in our centre was quite high and the time of presentation played a crucial role. Prevention strategies focusing on predictors of SSI is necessary to reduce the rate of SSI in our setting.

CONTEXTE: La péritonite secondaire est une affection chirurgicale d'urgence fréquente avec diverses étiologies gérées par des chirurgiens du monde entier. Une morbidité importante associée à cela est l'infection postopératoire du site chirurgical (SSI). Une meilleure stratégie de prévention peut être mise en place si cette complication chez les patients peut être correctement prédite. L'étude visait à identifier les facteurs chez les patients atteints de péritonite qui ont une incidence significative sur le développement d'une SSI postopératoire. MÉTHODE: Au total, cinquante patients opérés pour une péritonite sur une période d'un an ont été étudiés. Des facteurs tels que l'âge, le sexe, les comorbidités, les symptômes de présentation, le moment de la présentation, le moment de l'intervention, les constatations peropératoires, la durée de la chirurgie et la SSI postopératoire ont été notés. Le test du chi carré, le test exact de Fisher et le test t de Student ont été utilisés pour tester les associations lorsque cela était approprié et une valeur de p < 0,05 était considérée comme statistiquement significative. RÉSULTATS: La péritonite était le plus souvent due à une appendicite rompue (46 %), suivie de près par une perforation de l'ulcère gastrique (42 %). L'incidence de la SSI était de 44 %. Pour les patients qui ont développé une SSI, le taux le plus bas a été observé dans les cas d'appendicite rompue (39,1%) et le plus élevé dans l'ulcère gastrique perforé (64,3 %), suivi de près par l'ulcère duodénal perforé (57,1 %). L'association entre le moment de la présentation et l'occurrence de la SSI était statistiquement significative (p = 0,028). CONCLUSION: Le taux de SSI (44 %) provenant de la péritonite dans notre centre était assez élevé et le moment de la présentation jouait un rôle crucial.Des stratégies de prévention axées sur les prédicteurs de la SSI sont nécessaires pour réduire le taux de SSI dans notre contexte.

Linear Scalp Incision in Brain Tumor Surgery: Intraoperative and Postoperative Considerations.

BACKGROUND: Although the linear scalp incision is commonly used in neurosurgical practice, a systematic study elucidating its pros and cons in a specific surgical setting is lacking. Herein, we analyzed our experience with linear scalp incision in brain tumor surgery and the impact on intraoperative variables and postoperative complications. METHODS: Patients undergoing brain tumor surgery (January 2014-December 2021) at 2 neurosurgical departments were included and divided into 2 groups: linear or flap scalp incision. Patients' demographics characteristics, surgical variables, and wound-related complications were analyzed. RESULTS: More than a total of 1036 craniotomies, linear incision (mean length 6cm) was adopted in 282 procedures (27.2%). Mean maximum diameter of the craniotomy was 5.25 cm, with no statistical difference between the 2 groups. In emergency surgery (36 cases), the linear and flap incisions were used indifferently. Linear incision was predominant in supratentorial and suboccipital lesions. Flap incision was significantly more frequent among meningiomas (P < 0.01). Neuronavigation, operative microscope, and subgaleal drain were more frequently used in the flap scalp incision group (P = 0.01). Overall complication rate was comparable to flap scalp opening (P = 0.40). CONCLUSIONS: The use of the linear incision was broadly applied for the removal of supratentorial and suboccipital tumors granting adequate surgical exposure with a low rate of postoperative complications. Tumors skull base localization resulted the only factor hindering the use of the linear incision. The choice of 1 incision over another didn't show to have any impact on intraoperative and postoperative variables, and it remains mainly based on surgeon expertise/preference.

'Dumpling suture method' versus traditional suture method of protective loop ileostomy in laparoscopic anterior rectal resection with specimen extraction through stoma incision: a retrospective comparative cohort study.

BACKGROUND: A diverting loop ileostomy (DLI) is performed in laparoscopic anterior rectal resection (LAR) surgery at high risk of anastomotic fistula. Minimally invasive surgery promotes postoperative recovery and cosmetics. To reduce abdominal trauma, specimen extraction through stoma incision (EXSI) is usually performed to avoid auxiliary abdominal incision with enlarged stomal incision. The traditional suture method (TSM) reduces the incision size by suturing the ends of the enlarged incision, leading to peristomal incisions and a higher risk of stomal complications. The study aimed to introduce the dumpling suture method (DSM) of PLI and compare this new method with TSM. MATERIALS AND METHODS: The authors propose a novel stoma suture technique, which utilized a method of skin folding suture to reduce the enlarged incision size. A retrospective analysis was conducted on 71 consecutive patients with rectal cancer who underwent LAR-DLI with EXSI, and the intraoperative details and postoperative outcomes of the two groups were measured. RESULTS: The DSM group showed a lower stomal complication rate (10.3 vs. 35.7%, P=0.016) than that of the TSM group. The scores of DET (Discoloration, Erosion, Tissue overgrowth), stomal pain, quality of life were all significantly lower in DSM group than in TSM group. In multivariate analysis, DSM was an independent protective factor for stoma-related complications. Operative time, time to first flatus, defecation and eat, nonstomal related postoperative complications were similar in both groups. CONCLUSION: DSM utilizes a method of skin folding suture to reduce the enlarged incision size, which is safe and effective in reducing the incidence of peristomal skin infections and stomal complications. This procedure offers a novel suturing approach for loop ileostomy with enlarged incision, effectively reducing the postoperative trauma and incidence of stomal complications.

Effect of continuous intra-incisional bupivacaine on postoperative pain in non-traumatic spinal fixation surgeries: a randomized controlled trial

Abstract Background Continuous injection of local anesthetics by using surgical wound catheters for postoperative pain relief has gained acceptance in recent years. However, whether this method can be alternatively used instead of systemic opioids in different surgical procedures has not yet been elucidated. Objectives The aim was to investigate the effect of continuous injection of bupivacaine through a catheter inside the surgical wound on reducing the postoperative pain of lumbar spine fusion surgeries. Methods In this clinical trial, 31 patients undergoing non-traumatic lumbar spine stabilization surgery were randomly assigned to receive (n = 15) or do not receive (n = 16) bupivacaine through a catheter inside the surgical wound, postoperatively. Pain intensity (NRS), dose of required morphine, and drug-related complications within 24 hours of intervention were assessed and compared by the Mann-Whitney and independent t-test. Results Mean pain intensity was significantly lower in the case group over the first postoperative hour in the recovery room (p < 0.001), which continued for the first 2 hours after entering the ward. The mean morphine intake was lower in the bupivacaine group during the first postoperative 24 hours (16 ± 0.88 vs. 7.33 ± 0.93 mg, p < 0.001). The two groups were not significantly different regarding drug-related complications. Conclusion Continuous intra-incisional infusion of bupivacaine helped better pain reduction during the early postoperative hours while sparing morphine consumption in the first postoperative day.

ABSTRACT Objective: to identify factors associated with complex surgical wounds in the breasts and abdomen in outpatients. Method: observational case-control study involving 327 patients, distributed into 160 cases (complex surgical wound) and 167 controls (simple surgical wound). Data were extracted from the medical records and a binary logistic regression model was used for analysis, considering a significance level of 5%. Results: the factors associated with greater chance of occurrence of complex surgical wound were 18 to 59 years of age (p = 0.003), schooling < 8 years (p = 0.049), radiotherapy (p < 0.001), hysterectomy (p = 0.003), glycemia (≤ 99 mg/dL) and arterial hypertension (p = 0.033), while quadrantectomy (p = 0.025) served as a protective factor. Conclusion: radiotherapy was the most significant factor for surgical wound complications. Glycemic alteration was an unexpected result and shows the need for further studies related to this topic.

Correlation between nutritional status and clinical results in patients undergoing spinal surgery / Correlação entre estado nutricional e resultados clínicos em pacientes submetidos à cirurgia da coluna vertebral / Correlación entre estado nutricional y resultados clínicos en pacientes sometidos a cirugía de la columna vertebral

ABSTRACT Objective: To investigate the relationship between preoperative vitamin D and albumin levels and postoperative quality of life in patients undergoing spinal surgery. Methods: Patients undergoing thoracic and lumbar spine surgery were evaluated in this prospective study. Their vitamin D and albumin levels were assessed before surgery and quality of life was measured by two questionnaires, Oswestry Disability Index (ODI) and Scoliosis Research Society - 22 (SRS-22), one year after the procedure. Data on infection occurrence and healing time were collected. Preoperative nutritional values and patients' quality of life were analyzed using the chi-square test and ANOVA for albumin and vitamin D, respectively. The relationship among nutritional status, healing time, and the occurrence of infection was evaluated by the Pearson correlation coefficient. Results: Forty-six patients were included and their mean nutritional values were 19.1 (6.6) ng/mL for vitamin D and 3.9 (0.6) g/dL for albumin [mean (standard deviation)]. No association was found between vitamin D and quality of life of patients measured by ODI (p=0.534) and SRS-22 (p=0.739) questionnaires. There was also no association between albumin levels and quality of life measured by ODI (p=0.259) and SRS-22 (p=0.076) questionnaires. No correlation was found between the healing time or occurrence of infection and nutritional values. Conclusions: There was no association between vitamin D and albumin levels and the surgical result, according to the patient's perception, besides the occurrence of complications with the surgical wound.

Efeito da estimulação elétrica no processo de reparação de tecido mole no palato: estudo em camundongos / Effect of electrical stimulation on soft tissue repair process at the palate: a study in mice

A estimulação elétrica (EE) tem sido usada no tratamento de lesões crônicas apresentando resultados favoráveis no fechamento da lesão cutânea entre outras aplicações clínicas. No entanto, a literatura carece de estudos avaliando se os efeitos da EE no fechamento da lesão oral. Diante disso, torna-se relevante investigar os efeitos da EE durante o processo de reparo da lesão oral em camundongos (Swiss). Métodos: Noventa animais foram divididos em grupos: Controle (C; n=45) que receberam a aplicação da EE com o aparelho desligado e Teste (EE; n=45) que receberam a EE (100 µA; 9 kHz; 660 mVpp; 1x/dia por 3 dias). Uma lesão de espessura total foi realizada com punch de biópsia de 1,5 mm de diâmetro. Os animais foram eutanasiados no 1o, 3o e 5o dia após a confecção da lesão. As amostras foram fixadas em paraformaldeído 4%, descalcificadas em ácido fórmico 20% e emblocadas em parafina. Os parâmetros avaliados foram: fechamento clínico da lesão; distância de reparação epitelial (DRE) e conjuntiva (DRC), concentração de citocinas IL-1ß, IL-6, IL-8, IL-10, TNF-α e VEGF; porcentagem de fibras colágenas e quantificação das proteínas de sinalização Smad2. Resultados: A área de fechamento clínico foi reduzida no grupo EE no 5º dia de avaliação (p=0,01). As DRE e DRC do grupo EE apresentaram menor distância em todos os tempos avaliados (p<0,05) com reduzida concentração de IL-6, TNF-α, IL-10 e VEGF (p<0,05). Não houve diferença na porcentagem de fibras colágenas e na phospho-Smad2. Conclusão: A EE teve efeito positivo nos parâmetros clínicos e histológicos com modulação da resposta inflamatória no início do processo de reparo da lesão(AU)

Background: Since Electrical Stimulation (ES) has used for chronic wounds treatment and other clinical applications showing favorable results in wound closure, it was hypothesized whether it could bring good results in oral wound closure. The aim was to investigate the ES effects during the oral wound healing process in mice (Swiss). Methods: Ninety animals were divided in groups: Control (C; n=45) which received a fictitious ES application, i.e. the ES applicance was shutted off and ES (ES; n=45) which received ES (100 µA; 9 kHz; 660 mVpp) once time a day for 3 days consecutively. A full thickness wound was done using a 1.5 mm diameter biopsy punch in the hard palate. The animals were euthanized on 1st, 3rd and 5th day post-wounding. The samples were fixed, decalcified and embedded in paraffin. The parameters evaluated were: clinical wound closure; distance of epithelial and connective wound edges (EWD and CWD); cytokines (IL-1ß, IL-6, IL-8, IL-10), TNF-α and VEGF by multiplex, percentage of collagen fibers and Smad proteins. Results: Clinical wound closure area was reduced on day 5 in ES group (p = 0.01). Both EWD and CWD distance were shorter in all times (p < 0.05) with a reduction of inflammatory cytokines production (p < 0.05). There were no difference in collagen percentage and phospho-Smad2. Conclusion: ES had a positive effect on clinical and histomorphometric wound closure outcomes showing a modulation of inflammatory response in the beginning of wound healing(AU)

Estudo comparativo de abdominoplastias com drenagem a vácuo e sem drenagem, mas com pontos de adesão / Comparative study between abdominoplasty with suction drainage and without suction drainage but using adhesion stitches

Introdução: A abdominoplastia é um dos procedimentos mais comumente realizados por cirurgiões plásticos. O objetivo do estudo foi avaliar a evolução e a ocorrência de complicações em pacientes submetidos à abdominoplastia pela técnica de ressecção em bloco, e observar se existe alguma diferença na evolução com a utilização de dreno ou de pontos de adesão. Métodos: Foi realizado um estudo prospectivo de 34 pacientes do sexo feminino, submetidas à abdominoplastia. Foram divididas em dois grupos alternadamente; em um deles foi utilizado dreno de aspiração a vácuo e no outro não, mas estes últimos receberam pontos de adesão. Resultados: Do total operado, houve algum grau de alargamento da cicatriz em 14,7% dos casos. Quando avaliado separadamente por grupo, aqueles que foram drenados tiveram incidência maior (23,53%) em comparação com os que receberam pontos de adesão (5,88%). Ocorreu um caso de trombose de veias superficiais de membros inferiores, com boa evolução. Foram diagnosticados três casos de seroma, todos no grupo com dreno. Eles representaram 8,82% do total estudado e 17,64% dos casos deste grupo. O resultado estético foi considerado muito bom por 94,12% das pacientes estudadas. Conclusões: A técnica de ressecção em bloco se mostrou segura, de fácil execução, com bons resultados estéticos e índices de complicações semelhantes às outras técnicas descritas na literatura. Os pontos de adesão foram eficazes na prevenção de complicações neste estudo.

Introduction: Abdominoplasty is one of the most common procedures performed by plastic surgeons. The goal of this study is to evaluate the outcome and the occurrence of complications in patients undergoing abdominoplasty using the en bloc resection technique, and to look for differences in evolution when a drain is used or is replaced with adhesion stitches. Methods: A prospective study was conducted on 34 female patients undergoing abdominoplasty. These were alternately placed into 2 groups: in one group suction drains were used, and in the other these were replaced with adhesion stitches. Results: Among all the cases, there was some degree of scar widening in 14.7% of patients. When analyzed by group, those who received drains had a higher incidence (23.53%) comparing to those who received adhesion stitches (5.88%). One patient had superficial vein thrombosis of the lower limbs with a good outcome. Three cases of seroma were diagnosed, all of them in the group using drains. These represent 8.82% of the entire study and 17.64% of the specific group. The aesthetic result was considered good by 94.12% of all patients. Conclusions: The en bloc resection abdominoplasty technique proved to be safe, easy to perform, assured good aesthetical results and had similar complication rates when compared to other techniques. The adhesion stitches were effective for preventing complications in this study.
