Continuation of low-dose acetylsalicylic acid during perioperative period of laparoscopic inguinal hernia repair is safe: results of a prospective clinical trial

Sutureless Repair for Open Treatment of Inguinal Hernia: Three Techniques in Comparison

Currently, groin hernia repair is mostly performed with application of mesh prostheses fixed with or without suture. However, views on safety and efficacy of different surgical approaches are still partly discordant. In this multicentre retrospective study, three sutureless procedures, i.e., mesh fixation with glue, application of self-gripping mesh, and Trabucco's technique, were compared in 1034 patients with primary unilateral non-complicated inguinal hernia subjected to open anterior surgery. Patient-related features, comorbidities, and drugs potentially affecting the intervention outcomes were also examined. The incidence of postoperative complications, acute and chronic pain, and time until discharge were assessed. A multivariate logistic regression was used to compare the odds ratio of the surgical techniques adjusting for other risk factors. The application of standard/heavy mesh, performed in the Trabucco's technique, was found to significantly increase the odds ratio of hematomas (p = 0.014) and, most notably, of acute postoperative pain (p < 0.001). Among the clinical parameters, antithrombotic therapy and large hernia size were independent risk factors for hematomas and longer hospital stay, whilst small hernias were an independent predictor of pain. Overall, our findings suggest that the Trabucco's technique should not be preferred in patients with a large hernia and on antithrombotic therapy.

Varying convalescence recommendations after inguinal hernia repair: a systematic scoping review

PURPOSE

The most recent international guideline on inguinal hernia management recommends a short convalescence after repair. However, surgeons' recommendations may vary. The objective of this study was to give an overview of the current convalescence recommendations in the literature subdivided on the Lichtenstein and laparoscopic inguinal hernia repairs.

METHODS

In this systematic review, three databases were searched in August 2021 to identify studies on inguinal hernia repairs with a statement about postoperative convalescence recommendations. The outcome was convalescence recommendations subdivided on daily activities, light work, heavy lifting, and sport.

RESULTS

In total, 91 studies fulfilled the eligibility criteria, and 50 and 58 studies reported about convalescence recommendations after Lichtenstein and laparoscopic repairs, respectively. Patients were instructed with a wide range of convalescence recommendations. A total of 34 Lichtenstein studies and 35 laparoscopic studies recommended resumption of daily activities as soon as possible. Following Lichtenstein repairs, the patients were instructed to resume light work after median 0 days (interquartile range (IQR) 0-0), heavy lifting after 42 days (IQR 14-42), and sport after 7 days (IQR 0-29). Following laparoscopic procedures, the patients were instructed to resume light work after median 0 days (IQR 0-0), heavy lifting after 14 days (IQR 10-28), and sport after 12 days (IQR 7-23).

CONCLUSION

This study revealed a broad spectrum of convalescence recommendations depending on activity level following inguinal hernia repair, which likely reflects a lack of high-quality evidence within this field.

The topical application of tranexamic acid to control bleeding in inguinal hernia surgery candidate patients: A randomized controlled trial

Background and objectives

Inguinal hernia surgery is a common procedure, especially for the elderly, who usually use anticoagulants and antiplatelet drugs. In this study, we evaluated the effectiveness of tranexamic acid (TXA) on the complications of inguinal hernia repair in patients using antiplatelets.

Patients and methods

This study is a randomized controlled trial that was performed during the 2018-2019 years. Forty patients with inguinal hernia and antiplatelet use were enrolled randomly into the two groups. In the intervention group, the patients received two injectable form (500mg/5 mL) of TXA, totally 10 mL as a topical application at the surgical site, and then the patient's surgical site was seen every 8 h for 48 h, and the patient was examined daily for one week.

Results

The mean length of hospitalization, seroma, hematoma and infection in the two groups were not statistically significant (P > 0.05). However, the duration of surgery in the TXA group was significantly shorter than in the control group (54.85 vs. 68.72 min) (P < 0.001). The mean bleeding during surgery was significantly lower in the TXA group than in the control group (P < 0.001).

Conclusion

The findings of present study indicate that topical TXA has a high ability to control bleeding. As a result, TXA is beneficial in terms of reducing bleeding and increasing the surgeon's satisfaction. Therefore, it is recommended that TXA be prescribed for patients requiring inguinal hernia surgery with a high risk of bleeding.

Perioperative Antiplatelet and Anticoagulant Management with Endodontic Microsurgical Techniques

INTRODUCTION

The purpose of this study was to review evidence-based recommendations for the safe perioperative management of patients undergoing endodontic microsurgery who are currently taking antiplatelet or anticoagulant medications. Using the PICO (Population, Intervention, Comparison, Outcome) format, the following scientific question was asked: In patients taking anticoagulant or antiplatelet agents, what is the available evidence in the management of endodontic microsurgery?

METHODS

MEDLINE, Scopus, Cochrane Library, and ClinicalTrials.gov databases were searched to identify current recommendations regarding the management of antiplatelet and anticoagulant medications in the context of outpatient dental surgical procedures. Additionally, the authors hand searched the bibliographies of all relevant articles, the gray literature, and textbooks. Because of the lack of clinical studies and evidence on this subject, articles and guidelines from other organizations and association position statements were included.

RESULTS

Because any minor surgery can become a major surgery, the treating doctor needs to best assess the risk of bleeding, especially if the surgery is anticipated to take longer than 45 minutes. Every patient should be stratified on a case-by-case basis. Consultation with the patient's physician is highly recommended.

CONCLUSIONS

In order to maximize the effects of these medications (to prevent thrombosis) while minimizing the potential risks (procedural hemorrhage), clinicians should be aware of the best available evidence when considering continuation or discontinuation of antiplatelet and anticoagulant agents perioperatively for endodontic microsurgery. Ideally, a joint effort from an expert panel for microsurgery would be warranted.

The safety and effectiveness of salvianolate in preventing perioperative venous thromboembolism in China: A PRISMA-compliant meta-analysis based on RCTs

BACKGROUND

Salvianolate, a common drug for stabilizing heart disease and Angina Pectoris, is considered to be off-label for preventing venous thromboembolism (VTE) or anticoagulation at present. However, many clinical studies have showed that salvianolate can effectively inhibit the deep-vein thrombosis (DVT) incidence, and prevent VTE of perioperative patients in the real world in China.

OBJECTIVE

This analysis aimed to evaluate the effectiveness and safety of salvianolate in preventing VTE in perioperative patients.

METHODS

Databases of PubMed, Cochrane Library, Embase, CNKI, Wanfang and VIP were searched until July 2019. Literature retrieval, data extraction and quality assessment were independently completed by two researchers and checked with each other. Review Manager 5.2 software was applied for meta-analysis.

RESULTS

A total of 429 studies were retrieved, including 11 randomized controlled trials (RCTs) with a total of 1149 subjects. Compared with low molecular weight heparin (LMWH) group alone, salvianolate combined LMWH group had lower DVT incidence in preventing perioperative thrombosis (2.75% and 14.23%, OR: 0.21, 95% CI:[0.08,0.53]; P = .0009). The incidence of adverse reactions of experimental group was similar to that of control group (1.79% and 2.31%, OR: 0.65, 95% CI:[0.18,2.35]. P = .51). Compared with the control group, D-dimer level (D-D), platelet count (PLT), fibrinogen (FIB), whole blood high shear viscosity (WBHSV), and whole blood low shear viscosity (WBLSV) were all significantly decreased (P < .01), and prothrombin time (PT) was significantly increased (P < .05).

CONCLUSION

Salvianolate combined LMWH has better effectiveness and the same safety in preventing venous thromboembolism in perioperative patients. However, due to the small number of included literatures, large sample studies are still needed to further verify this conclusion.

Drainage decreases the seroma incidence in laparoscopic transabdominal preperitoneal (TAPP) hernia repair for large inguinoscrotal hernias

BACKGROUND

Seroma is a common and inevitable postoperative complication in transabdominal preperitoneal (TAPP) hernia repair, especially in patients with large inguinoscrotal hernias. However, studies have rarely reported drainage in TAPP for large inguinoscrotal hernias.

METHODS

Sixty-five patients with 78 large indirect inguinoscrotal hernias who underwent TAPP procedure with drainage between September 2016 and December 2019 were enrolled in this study. 181 patients with Type Ⅲ indirect inguinal hernias (European Hernia Society (EHS) classification, hernia defect >3 cm) who underwent TAPP without drainage (no-drainage group) between January 2019 and December 2019 were included for a comparison. In the drainage group, a 12-Fr drainage tube was inserted into the distal hernia sac via the preperitoneal space to decrease the incidence of seroma.

RESULTS

There was no conversion to open procedures in all the patients. The operative time (56.5 ± 8.4 VS 54.8 ± 9.6 min, unilateral; 95.8 ± 10.4 VS 92.1 ± 13.9 min, bilateral), blood loss (5.9 ± 1.9 VS 5.6 ± 1.7 mL), visual analogue scale score on postoperative day 1 (2.3 ± 0.5 VS 2.2 ± 0.5) and postoperative hospital stay (1.1 ± 0.3 VS 1.0 ± 0.2 days) in the drainage group were equivalent to those in the no-drainage group (p > 0.05). The mean length of drainage was 5.2 ± 1.3 days. The drainage group had a significantly lower incidence of seroma than the no-drainage group (1.5% VS 9.4%, p = 0.037). The postoperative complications including haematoma, recurrence and chronic pain were comparable in the two groups.

CONCLUSION

Drainage with appropriate duration is a feasible, safe and effective measure to decrease the incidence of seroma in TAPP for patients with large inguinoscrotal hernias.
