Sutureless repair techniques for post-infarction left ventricular free wall rupture.

Left ventricular free wall rupture after acute myocardial infarction is uncommon but lethal and is still associated with high mortality rates. This paper presents the surgical treatment options and clinical management for post-infarction left ventricular free wall rupture. Various types of techniques, specifically sutureless repair using TachoComb/TachoSil, and intraoperative video images are discussed. Currently, sutureless repair is the most recommended treatment option when possible. However, appropriate selection of the surgical procedure remains important.

[Use of topical haemostatic agents in cardiovascular surgery]. / Ispol'zovanie mestnykh gemostaticheskikh sredstv v serdechno-sosudistoi khirurgii.

The problem of haemostasis in cardiovascular surgery is of current concern. Recent trends are towards increased use of topical haemostatic agents. Tachocomb has been used for more than 30 years in abdominal surgery and oncology. The purpose of the present publication is to analyse the literature data and formulate the indications for the use of Tachocomb in cardiovascular surgery. Multicenter randomized and local studies have demonstrated efficacy of Tachocomb in treatment of surgical haemorrhage in operations on the heart, thoracic aorta, carotid arteries and lower-limb arteries, resulting in significantly decreased time to achieve haemostasis, decreased volume of blood loss and haemotrasfusion, as well as reduced frequency of complications. Also shown was economic efficacy, including a shortened length of patients' hospital stay. This is followed by describing a wide spectrum of examples of alternative use of Tachocomb, including its use for seamless closure of defects of cardiac chamber walls, aero- and lymphostasis, prevention of formation of commissures. Convincing experimental and clinical results make it possible to formulate a series of indications for the use of Tachocomb in cardiovascular surgery.

Off-pump sutureless repair for ischemic left ventricular free wall rupture: a systematic review.

BACKGROUND: Clinical results of ischemic left ventricular free-wall rupture show high mortality rates. METHODS: We reviewed studies published after 1993 on PubMed. RESULTS: A sutureless technique using fibrin glue sheets or patches with/without fibrin glue might contribute to improved clinical results. However, some technique limitations remain for blowout-type ruptures, and the possibility of a pseudoaneurysm formation at the repair site after surgery should be considered. CONCLUSIONS: The sutureless technique can be a promising strategy for the treatment of ischemic rupture, but serial echocardiographic studies should be mandatory for diagnosing a left ventricular pseudoaneurysm formation thereafter.

Comparison of TachoSil and TachoComb in patients undergoing liver resection-a randomized, double-blind, non-inferiority trial.

BACKGROUND: This study aimed to demonstrate the noninferior efficacy of TachoSil vs. TachoComb in Japanese patients undergoing liver resection and to assess the safety of TachoSil vs. TachoComb in these patients. METHODS: This randomized, double-blind, noninferiority study (JapicCTI-090684) involved participants scheduled for liver resection/living donors (age ≥ 20 years). TachoSil or TachoComb (1:1 allocation ratio) was applied to control persistent exudative bleeding after primary hemostasis during liver resection/removal for donation. The primary outcome was hemostasis 5 min after study treatment application. The 95% confidence interval (CI) for the difference in the proportion of participants with hemostasis 5 min after application of TachoSil/TachoComb was determined; noninferiority of TachoSil was indicated if the lower limit of the CI was ≥-14%. Adverse events (AEs) were recorded. RESULTS: All participants in the efficacy analysis (TachoSil: 54/54, 100%; TachoComb: 54/54, 100%) achieved hemostasis 5 min after study treatment application. Therefore, TachoSil was noninferior to TachoComb. All participants experienced ≥1 AE; however, none discontinued because of an AE. Most (≥97.8%) AEs were mild or moderate in severity. CONCLUSIONS: These findings confirm the safety profile and noninferior hemostatic efficacy of TachoSil compared with TachoComb.

The efficacy of TachoComb on reducing postoperative complications after tonsillectomy in children.

OBJECTIVE: A fibrinogen/thrombin-based collagen fleece (TachoComb) is a powerful topical hemostatic agent that has been widely used in various surgical specialties with a favorable outcome. The purpose of this study was to investigate the effect of TachoComb application on postoperative complications after tonsillectomy. MATERIALS AND METHODS: A total of 1633 children had undergone tonsillectomy with or without adenoidectomy were included in this study. After removal of both tonsils, 1057 patients (64.7%) were treated with TachoComb on the tonsillectomy site and 576 without TachoComb. Post-tonsillectomy pain, hemorrhage rates, re-admission rates, and emergency surgery rates for post-tonsillectomy hemorrhage were evaluated between patients who received TachoComb and those who did not. RESULTS: TachoComb treatment significantly reduced post-tonsillectomy pain and emergency surgery rates for post-tonsillectomy hemorrhage. However, postoperative hemorrhage rate and re-admission rates for post-tonsillectomy hemorrhage were not statistically significant between TachoComb treatment group and control group. No patients had complications or adverse reactions after TachoComb treatment. CONCLUSIONS: The use of TachoComb after tonsillectomy significantly reduces pain and emergency surgery for severe post-tonsillectomy hemorrhage without an apparent adverse effect. Therefore, TachoComb may be a useful adjuvant in terms of efficacy and safety after tonsillectomy.

Use of a Fibrinogen/Thrombin-Based Collagen Fleece (TachoComb, TachoSil) With a Stapled Closure to Prevent Pancreatic Fistula Formation Following Distal Pancreatectomy.

BACKGROUND/PURPOSE: Postoperative pancreatic fistula formation remains a source of significant morbidity following distal pancreatectomy. The aim of this study was to evaluate the rate of clinically significant fistulas (International Study Group on Pancreatic Fistula grade B and grade C) after distal pancreatectomy using a fibrinogen/thrombin-based collagen fleece (TachoComb, TachoSil) with a stapled closure. METHODS: Seventy-five patients underwent distal pancreatectomy at our institution between January 2005 and March 2014. A fibrinogen/thrombin-based collagen fleece was applied to the staple line of the pancreas before stapling. RESULTS: Twenty-six patients (34.7%) developed a pancreatic fistula, 8 patients (10.7%) developed a grade B fistula, and no patients developed a grade C fistula. The duration of the drain was significantly different in patients with or without a pancreatic fistula (8.0 ± 4.5 vs. 5.4 ± 1.3 days, P = .0003). Histological analysis showed that there was a tight covering with the fibrinogen/thrombin-based collagen fleece. CONCLUSION: The fibrinogen/thrombin-based collagen fleece (TachoComb, TachoSil) with a stapled closure has low rates of fistula formation and provides a safe alternative to the conventional stapled technique in distal pancreatectomy.
