A novel approach to teaching placement of a B-lynch suture: description of technique and validation of teaching model.

ABSTRACT: INTRODUCTION: Postpartum hemorrhage is a major cause of maternal morbidity and mortality throughout the world and uterine atony is the leading cause of postpartum hemorrhage. The B-Lynch brace suture is a fertility-sparing approach to treating intractable uterine atony at the time of cesarean delivery. However, many obstetricians lack confidence to perform this procedure, which they may not have performed during residency. In order to train all residents to perform the B-Lynch brace suture, we developed a realistic model by using a flank steak to imitate a gravid uterus. METHODS: A convenience sample of obstetrics-gynecology faculty and residents at different levels of training at a single large hospital participated in this pilot project. Each physician reported self-perceived understanding of and confidence in performing the B-Lynch procedure before and immediately after practicing the technique using the flank-steak model, via a Likert-type survey (scale 1 = low, 5 = high). A Wilcoxon matched-pairs signed rank test was used to compare the before and after responses. RESULTS: Thirty-four participants completed the flank-steak model training and pretraining/posttraining surveys. The median score (range) for self-perceived understanding was 4 (2-5) and increased to 5 (4-5) (P < .01) after exposure to the training model. The confidence scores rose from 3 (1-5) to 5 (4-5) (P < .01) after training. CONCLUSION: The flank-steak model for teaching the B-Lynch suture significantly improved resident and faculty self-perceived understanding of and confidence in performing this procedure, which is otherwise rarely practiced in residency.

Novel adaptation of a running suture technique in a mouse model of corneal transplantation.

Project description:Several murine models of corneal transplantation have been developed over the years to study the immunopathological processes that lead to the failure of grafted corneas. In all of them, the classic eight interrupted sutures technique is utilized for transplanting the donor cornea on the host bed. However, in clinical practice, a single continuous suture with a single knot is generally performed for corneal transplantation. Here, we describe the adaptation of the single continuous suture technique in a mouse model of corneal transplantation.

Tension band wiring versus suture anchor technique in patellar inferior pole fracture: Novel double row suture anchor technique.

Project description:IntroductionPatellar inferior pole fractures are challenging to obtain sufficient fixation. The purpose of this retrospective, case-controlled study was to compare the clinical and radiological outcomes between tension band wiring (TBW) and our novel double-row suture anchor (SA) technique in patellar inferior pole fractures.Materials and methodsThis retrospective study included patients who underwent TBW or SA fixation for patellar inferior pole fractures from 2015 to 2019. A total of 63 patients were divided into two groups according to the surgical procedure: the TBW group (n = 35) and the SA fixation group (n = 28). The visual analog scale score, range of motion of the knee, Lysholm score, Kujala patellofemoral score, and patient satisfaction score were evaluated for clinical and functional outcomes. Radiological outcomes included the time to radiological union, loss of reduction, and the Insall-Salvati (IS) ratio.ResultsSignificant improvements in clinical outcomes were observed in both groups with no significant differences. Bone union was achieved in all patients, and there was no significant difference in the time to radiological union and the IS ratio between the two groups. All patients in the TBW group underwent additional surgeries for implant removal. However, none of the patients in the SA group underwent implant removal or experienced skin irritation.ConclusionOur novel double-row SA technique could provide comparable fixation strength and good clinical outcomes, with fewer complications in patellar inferior pole fractures. This novel SA technique is a satisfactory alternative treatment for patellar inferior pole fractures.

Arthroscopic suture anchor tenodesis: loop-suture technique.

Project description:With advancements in arthroscopic surgery, arthroscopic biceps tenodesis with suture anchor recently has been reported to be a reasonable option for the treatment of biceps pathologies, especially for those that are symptomatic or accompanied by a rotator cuff tear. We introduce our technique of arthroscopic biceps tenodesis with suture anchor that we call the loop-suture technique, which is constructed with 1 loop strand and another sutured strand. This technique can help to improve biceps grip and simultaneously minimize longitudinal splitting of the tendon. In addition, it is relatively simple and can be performed with the use of conventional devices and arthroscopic portals used for rotator cuff repair, without the formation of additional portals or a separate incision for the tenodesis.

The Exchange-Free Technique: A Novel Technique for Enhancing Surpass Flow Diverter Placement.

Project description:BackgroundFollowing flow diverter placement, approximately 20% of intracranial aneurysms remain as residual aneurysms at 1 year. Device malapposition is a cause of residual aneurysms after flow diversion. We present a new and straightforward technique (exchange-free technique [EFT]) to enhance apposition of the surpass flow diverter (SFD), the only over-the-wire flow diverter currently available.Materials and methodsWe deployed laser-cut mini stents through the inner deployment catheter of the SFD. This maneuver was performed simply by withdrawing the micro-guidewire from its lumen and replacing it with a mini-stent (stents deliverable through microcatheters with inner diameter of 0.0165 inches), without a need to re-cross the deployed SFD or an exchange maneuver. All aneurysms in which this technique was utilized were retrospectively reviewed.ResultsTwenty-eight patients (20 females) with 30 treated aneurysms were identified. The mean aneurysm diameter was 10.2 ± 6.6 mm. Technical success rate was 96.6% (29/30 aneurysms). There was no mortality or permanent morbidity related to the procedures. Except for the patient treated for an iatrogenic, surgery-related internal carotid artery pseudoaneurysm who died secondary to consequences of multiple surgeries, no cases of mortality or permanent morbidity were noted. Complete aneurysm occlusion rates were 78.2%, 82.1%, and 95.2% at 0-3, 3-6, and 9-12 months, respectively. None of the patients were re-treated.ConclusionEFT is a simple and fast technique which was not associated with adverse effects in our series. The higher aneurysm obliteration rate obtained with EFT is probably the result of better wall apposition of the SFD.

Vertical Continuous Meniscal Suture Technique.

Project description:Meniscal injuries are common in the population, representing the major cause of functional impairment in the knee. Vertical longitudinal injuries of the meniscus can be stable or unstable. When extensive, they are commonly unstable and can lead to clinical signs of significant functional disability. Vertical longitudinal injuries have the best prognosis for repair, especially when occurring in the meniscal periphery, called the red-red zone. A recently developed type of meniscal suture device called Meniscus 4 A-II enables the surgeon to perform a meniscal suture from the inside-out continuously, reducing surgical time. Because it allows the surgeon to use a single and inexpensive device to repair the entire injury, costs are significantly reduced. Here, an approach to carry out continuous meniscal repair with vertical sutures is described. This technique warrants excellent stability to the meniscal repair, increasing the chances of a successful outcome. We believe that the popularization of the repair technique from the inside out using the Meniscus 4-All device will help many surgeons around the world save menisci that otherwise would have a great chance of being excised, since it is a cheap, reproducible, and easy-to-handle device.

Hybrid suture technique vs simple suture technique for antero-inferior labral tears: Two years' clinical outcomes.

Project description:BackgroundWe previously reported a hybrid suture technique, wherein mattress and simple suturing are used to create Mason-Allen configuration, with low recurrence rates. This comparative study looking at the two years' clinical outcomes of arthroscopic anterior labral repair using the hybrid suture technique versus simple suture technique.MethodsWe identified 103 patients who underwent arthroscopic anterior labral repair from 2010 to 2015 with 2-year follow-up. The patients were categorized into two groups: hybrid suture technique (65 patients) and simple suture technique (38 patients). Clinical outcomes measures included UCLA shoulder score, Constant Shoulder Score, Numerical Pain Rating Scale, and Oxford Instability score.ResultsMean age of the patients was 27.02 ± 9.76 years (17-63), with 91 males and 12 females. At 24 months, both groups showed significant improvement in post-operative clinical scores compared to pre-operation. The patients in hybrid sutures technique demonstrated significant improvement in Constant Shoulder Score, UCLA shoulder score and Oxford Instability score compared to simple suture group at 3 months follow up. (121.98 ± 21.05 vs 109.32 ± 21.15, p < 0.05; 65.5 ± 19 vs 57.4 ± 17.6, p < 0.05; 27.3 ± 5.7 vs 23.7 ± 5.0, p < 0.05; 29.3 ± 8.9 vs 33.4 ± 8.2, p < 0.05). The postoperative recurrence rate was comparable between both groups (hybrid suture group 7.81% vs simple suture group 7.84%).ConclusionsArthroscopic anterior labral repair with hybrid suture technique offers significant early improvements in clinical scores and low recurrence rate compared to simple suture technique at 2-year follow-up.Level of evidenceLevel III; Retrospective Cohort Design; Treatment study.

Endoscopically-Assisted Zygomatic Implant Placement: A Novel Approach.

Project description:BackgroundZygomatic implants (ZIs) have been proposed as a valid alternative to advance bone-grafting procedures in the rehabilitation of the severe atrophied upper maxilla, with a reported overall success rate of more than 95 %. Otherwise, the use of the endoscope has been described for the treatment of maxillofacial trauma, orthognatic surgical procedures, sinonasal pathology, salivary gland disease, and TMJ internal derangement. A careful identification of anatomical landmarks is of utmost importance while trying to avoid potential complications during the insertion of ZIs. Several approaches for ZI insertion have been reported, such as the classical approach; the sinus slot technique; and the exteriorized approach.Materials and methodsThe authors first introduce in the literature the endoscopically-assisted approach for the insertion of ZIs in the extremely severe atrophic maxilla.ResultsOptimal results in terms of ZIs positioning with no damage to surrounding structures were obtained.ConclusionsBy means of this new technique the surgeon may minimize the risk of complications related to the damage of neighbouring anatomic structures, such as orbital disruption or infraorbitary nerve damage, while ensuring an adequate drill positioning and angulation for the placement of one or two implants into the zygomatic bone.

Fluoroscopy-Guided Suture Anchor Placement for Acetabular Labrum Repair.

Project description:A narrow safe angle exists for placing suture anchors into the acetabular rim during arthroscopic acetabular labrum repair. Intra-articular suture anchor placement has been reported, and cadaver studies have shown the highest risk of errant suture anchor placement at the anterior acetabular rim. We describe a technique using intraoperative fluoroscopy to guide suture anchor placement into the anterior and superior acetabular rim, which may reduce the risk of iatrogenic injury during arthroscopic acetabular labrum repair.

Novel Stent Placement Technique for Intestinal Stenosis Assisted by an Ultrafine Endoscope

Project description:Colorectal cancer is the third most common cancer worldwide and results in 8-25% acute malignant bowel obstruction. Since Dohmoto et al. first applied and reported the self-expanding metal stents (SEMS) in the treatment of colorectal stenosis, they have been widely used not only as an alternative treatment as a bridge to surgery (BTS), but also as a mean of palliative option for stenosing lumen in clinical practice. Numerous publications have reported that the stent placement technique showed 75% to 100% technical success rates and 84% to 100% clinical success rates. However, it is sometimes difficult to place due to the distorted anatomy or acute angulations in patients and other conditions with poor endoscopic visualization with the normal colonoscope. The aims of this study were to present our results with two novel SEMS implantation techniques.
