UNASSIGNED: Haemostasis-related complications associated with Medtronic Tri-stapleTM with preloaded buttress material and the novel, naked AEONTM gastrointestinal staplers have not been extensively studied in bariatric surgery. The study aimed to assess and compare the 30-day haemostasis-related complications between Medtronic Tri-stapleTM and AEONTM GIA staplers.
UNASSIGNED: A retrospective analysis was performed on data from patients who underwent primary or revision sleeve gastrectomy (SG) or the sleeve component of single anastomosis duodeno-ileal bypass with SG (SADI-S) in a private hospital in Australia between November 2021 and December 2022. The surgeries were performed by a single surgeon, using either Medtronic Tri-stapleTM or AEONTM staplers.
UNASSIGNED: The analysis included 250 patients, with the first 125 consecutive patients receiving staple line using the Medtronic Tri-stapleTM GIA stapler and the subsequent 125 patients receiving staple line using the AEONTM GIA stapler. Statistical analysis revealed no significant differences in the distribution of surgical procedures between the Medtronic and AEON groups. In the AEON group, there were statistically higher numbers of diabetics and former tobacco users, while other preoperative characteristics did not significantly differ between the two groups. The AEON group had a significantly longer mean operative time, while the length of hospital stay was significantly shorter. No intraoperative or 30-day complications, deaths, emergency room visits, readmissions, or reoperations were observed in either group.
UNASSIGNED: The novel, naked AEONTM stapler demonstrated non-inferiority to the established Medtronic Tri-StapleTM with preloaded buttress material in achieving hemostasis and maintaining staple-line integrity in bariatric surgery.

Electrosurgical and ultrasonic devices are used in surgical procedures for hemostatic sealing and bisection of vascular tissues. Previous benchtop studies alternatively demonstrated successful infrared laser sealing and cutting of blood vessels, in a sequential, two-step approach. This study describes a smaller, laparoscopic device compatible design, and simultaneous approach to sealing and bisection of vessels, with potential optical feedback. A 1470-nm infrared diode laser sealed and bisected 40 porcine renal arteries, ex vivo. A reciprocating, side-firing, optical fiber, housed in a transparent square quartz optical chamber (2.7 × 2.7 × 25 mm outer dimensions), delivered laser energy over an 11 mm scan length, with a range of incident powers (41-59 W) and treatment times (5-21 s). Vessel diameters ranged from 2.5 to 4.8 mm. Vessel burst pressure measurements were performed on each cut end (n = 80) with success indicated by pressures exceeding 360 mmHg. All vessel ends were successfully sealed and bisected (80/80). The highest incident power, 59 W, yielded short treatment times of 5-6 s. Peak temperatures on the external chamber surface reached 103 oC. Time to cool down to body temperature measured 37 s. Infrared lasers simultaneously seal and bisect blood vessels, with treatment times comparable to, and temperatures and cooling times lower than reported for conventional devices. Future work will focus on integrating the fiber and chamber into a standard 5-mm-outer-diameter laparoscopic device. Customization of fiber scan length to match vessel size may also reduce laser energy deposition, enabling lower peak temperatures, treatment times, and cooling times.

BACKGROUND: During laparoscopic cholecystectomy for acute cholecystitis, it is often difficult to keep the surgical view dry because of inflammation-related tissue fragility and susceptibility to bleeding. The resulting inadequate surgical view can lead to bile duct or vascular injury. Soft coagulation systems are used to achieve hemostasis during various surgeries; however, the usefulness of soft coagulation during laparoscopic cholecystectomy for acute cholecystitis is unclear. We here demonstrate the usefulness and feasibility of blunt dissection and soft coagulation during this procedure.
METHODS: We used blunt dissection and soft coagulation when performing laparoscopic cholecystectomy on two patients with acute cholecystitis. As with conventional laparoscopic cholecystectomy, four ports were inserted. After cutting the serosa by electrocautery, blunt dissection using soft coagulation was performed, exposing the inner subserosa. Maintaining this layer using blunt dissection with soft coagulation achieved a sufficiently clear view for safety. After resecting the cystic artery and duct, the gallbladder bed was also dissected by blunt dissection with soft coagulation. Blood loss was <20 mL in both patients.
CONCLUSIONS: Blunt dissection with soft coagulation may be a useful and feasible means of keeping the surgical view dry and minimizing blood loss during laparoscopic cholecystectomy for acute cholecystitis.

During vascular interventions, connections that link arteries, veins, or synthetic grafts, which are known as an \'anastomosis\', may be necessary. Vascular anastomoses can bleed from the needle holes that result from the creation of the anastomoses. Various surgical options are available for achieving hemostasis, or the stopping of bleeding, including the application of sealants directly onto the bleeding vessels or tissues. Sealants are designed for use in vascular surgery as adjuncts when conventional interventions are ineffective and are applied directly by the surgeon to seal bleeding anastomoses. Despite the availability of several different types of sealants, the evidence for the clinical efficacy of these hemostatic adjuncts has not been definitively established in vascular surgery patients.
To evaluate the benefits and harms of sealants as adjuncts for achieving anastomotic site hemostasis in patients undergoing vascular surgery.
The Cochrane Vascular Information Specialist conducted systematic searches of the following databases: the Cochrane Vascular Specialised Register via the Cochrane Register of Studies; the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE via Ovid; Embase via Ovid ; and CINAHL via EBSCO. We also searched ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform for clinical trials. Reference lists of included trials and relevant reviews were also searched. The latest search date was 6 March 2023.
We included randomized controlled trials that compared fibrin or synthetic sealant use with alternative interventions (e.g. manual compression, reversal of anticoagulation) for achieving anastomotic-site hemostasis in vascular surgery procedures. We included participants who underwent the creation of an anastomosis during vascular surgery. We excluded non-vascular surgery patients.
We have used standard Cochrane methods. Our primary outcomes were time to hemostasis, failure of hemostatic intervention, and intraoperative blood loss. Our secondary outcomes were operating time, death from bleeding complications up to 30 days, postoperative bleeding up to 30 days, unplanned return to the operating room for bleeding complications management up to 30 days, quality of life, and adverse events. We used GRADE to assess the certainty of evidence for each outcome.
We found 24 randomized controlled trials that included a total of 2376 participants who met the inclusion criteria. All trials compared sealant use with standard care controls, including oxidized cellulose, gelatin sponge, and manual compression. All trials were at high risk of performance bias, detection bias, and other sources of bias. We downgraded the certainty of evidence for risk of bias concerns, inconsistency, imprecision and possible publication bias. Combining data on time to hemostasis showed that sealant use may reduce the mean time to hemostasis compared to control (mean difference (MD) -230.09 seconds, 95% confidence interval (CI) -329.24 to -130.94; P < 0.00001; 7 studies, 498 participants; low-certainty evidence). Combining data on failure of hemostatic intervention showed that sealant use may reduce the rate of failure compared to control, but the evidence is very uncertain (risk ratio (RR) 0.46, 95% CI 0.35 to 0.61; P < 0.00001; 17 studies, 2120 participants; very low-certainty evidence). We did not detect any clear differences between the sealant and control groups for intraoperative blood loss (MD -32.69 mL, 95% CI -96.21 to 30.83; P = 0.31; 3 studies, 266 participants; low-certainty evidence); operating time (MD -18.72 minutes, 95% CI -40.18 to 2.73; P = 0.09; 4 studies, 436 participants; low-certainty evidence); postoperative bleeding (RR 0.78, 95% CI 0.59 to 1.04; P = 0.09; 9 studies, 1216 participants; low-certainty evidence), or unplanned return to the operating room (RR 0.27, 95% CI 0.04 to 1.69; P = 0.16; 8 studies, 721 participants; low-certainty evidence). No studies reported death from bleeding or quality of life outcomes.
Based on meta-analysis of 24 trials with 2376 participants, our review demonstrated that sealant use for achieving anastomotic hemostasis in vascular surgery patients may result in reduced time to hemostasis, and may reduce rates of hemostatic intervention failure, although the evidence is very uncertain, when compared to standard controls. Our analysis showed there may be no differences in intraoperative blood loss, operating time, postoperative bleeding up to 30 days, and unplanned return to the operating room for bleeding complications up to 30 days. Deaths and quality of life could not be analyzed. Limitations include the risk of bias in all studies. Our review has demonstrated that using sealants may reduce the time required to achieve hemostasis and the rate of hemostatic failure. However, a significant risk of bias was identified in the included studies, and future trials are needed to provide unbiased data and address other considerations such as cost-effectiveness and adverse events with sealant use.

BACKGROUND: Intraoperative blood loss and postoperative hemorrhage affect outcomes after liver resection. GATT-Patch is a new flexible, pliable hemostatic sealant patch comprising fibrous gelatin carrier impregnated with N-hydroxy-succinimide polyoxazoline. We evaluated safety and performance of the GATT-Patch for hemostasis at the liver resection plane.
METHODS: Adult patients undergoing elective open liver surgery were recruited in three centers. GATT-Patch was used for minimal to moderate bleeding at the liver resection plane. The primary endpoint was hemostasis of the first-treated bleeding site at 3 min versus a prespecified performance goal of 65.4%.
RESULTS: Two trial stages were performed: I (n = 8) for initial safety and II (n = 39) as the primary outcome cohort. GATT-Patch was applied in 47 patients on 63 bleeding sites. Median age was 60.0 (range 25-80) years and 70% were male. Most (66%) surgeries were for colorectal cancer metastases. The primary endpoint was met in 38 out of 39 patients (97.4%; 95% confidence interval: 84.6%-99.9%) versus 65.4% (P < 0.001). Of all the 63 bleeding sites, hemostasis was 82.7% at 30, 93.7% at 60, and 96.8% at 180 s. No reoperations for rebleeding or device-related issues occurred.
CONCLUSIONS: When compared to a performance goal derived from state-of-the-art hemostatic agents, GATT-Patch for the treatment of minimal to moderate bleeding during liver surgery successfully and quickly achieved hemostasis with acceptable safety outcomes.

BACKGROUND: The use of hemostatic agents by general surgeons during abdominal operations is commonplace as an adjunctive measure to minimize risks of postoperative bleeding and its downstream complications. Proper selection of products can be hampered by marginal understanding of their pharmacokinetics and pharmacodynamics. While a variety of hemostatic agents are currently available on the market, the choice of those products is often confusing for surgeons. This paper aims to summarize and compare the available hemostatic products for each clinical indication and to ultimately better guide surgeons in the selection and proper use of hemostatic agents in daily clinical practice.
METHODS: We utilized PubMed electronic database and published product information from the respective pharmaceutical companies to collect information on the characteristics of the hemostatic products.
RESULTS: All commercially available hemostatic agents in the US are described with a description of their mechanism of action, indications, contraindications, circumstances in which they are best utilized, and expected results.
CONCLUSIONS: Hemostatic products come with many different types and specifications. They are valuable tools to serve as an adjunct to surgical hemostasis. Proper education and knowledge of their characteristics are important for the selection of the right agent and optimal utilization.

Hemostatic procedures for controlling nasal bleeding in refractory diseases such as hereditary hemorrhagic telangiectasia (HHT) can be challenging. In this report, we present a novel technique for underwater endoscopic endonasal hemostatic surgery, which was performed on a 69-year-old man with HHT. The patient had been experiencing frequent episodes of nasal bleeding and had many telangiectasias in the nasal cavity, which were the cause of the bleeding. These telangiectasias were effectively treated using a coblation device in combination with an endoscope lens-cleaning system that supplied saline to create stable underwater conditions. There are several advantages to this technique, including provision of a stable and clear endoscopic field of view, allowing for better visualization of the surgical site. This makes it easier to identify bleeding points and ensure accurate hemostasis. Additionally, the hydrostatic pressure created by the underwater environment helps to reduce bleeding during the procedure. However, it is important to take careful precautions to prevent water from entering the lower airway. With this precautionary measure, this technique is particularly useful in managing bleeding in patients with HHT.

UNASSIGNED: This study evaluated the efficacy of the Minimally Invasive Targeted Resection (MiTR) device, a novel electrosurgical instrument that allows for targeted excision of a lung abnormality while using bipolar radiofrequency (RF) energy to seal blood vessels and airways.
UNASSIGNED: The MiTR system was evaluated in 7 acute and 2 chronic porcine (7-day) models to evaluate the efficacy of tissue excision with bipolar RF sealing of blood vessels and airways and application of an autologous blood patch into the excised tissue cavity. Air leak was recorded for all evaluations. The study was approved by the institutional ethical board.
UNASSIGNED: Nineteen lung tissue samples, measuring 2.5 cm long × 1.2 cm diameter, were excised. In 8 of 9 animals (89%), hemostasis and pneumostasis were observed visually at the completion of the procedure. In 2 of 2 chronic animals (100%), hemostasis and pneumostasis persisted for the 7-day observation period. Histologic examination of the excised samples showed preservation of the core parenchymal architecture without evident tissue damage of the samples that would impair pathologic analysis.
UNASSIGNED: Percutaneous resection of targeted lung tissue with the MiTR system demonstrated hemostasis and pneumostasis while obtaining a histologically intact sample. After regulatory approval, the use of this device could offer more tissue for analysis than a transthoracic needle biopsy or bronchoscopy and a far less invasive alternative to video-assisted thoracic surgery or thoracotomy. This may also expand patient and physician options for the early diagnosis and treatment of lung cancer.
