Background: Pancreaticojejunostomy, an independent risk factor for pancreatic fistula, is the cause of several postoperative complications of pancreaticoduodenectomy. As suturing in minimally invasive surgery is difficult to perform, more simplified methods are needed to guarantee a safe pancreatic anastomosis. The concept of "biological healing" proposed in recent years has changed the conventional understanding of the anastomosis, which recommends rich blood supply, low tension, and loose sutures in the reconstruction of the pancreatic outflow tract.

Nasal valve insufficiency can be addressed using endonasal and open structure surgical techniques. However, some patients may prefer or be better suited for minimally invasive techniques that allow for more expedient treatment in the clinical setting. Techniques include internal dilators, external dilators, suture suspension, lateral wall implants, and radiofrequency remodeling. Read More

Objective: To report the long-term postoperative outcomes of transsclerally sutured intraocular lenses (IOLs), in which the haptics were correctly fixated into the ciliary sulcus using an auxiliary device and endoscope.

Methods And Analysis: Data were collected from eyes that were followed up for at least 12 months after ciliary sulcus suture fixation of an IOL using an auxiliary device for securely placing the IOL haptics to the ciliary sulcus, which was confirmed using intraoperative endoscopy in all cases. The corrected distance visual acuity (CDVA), refractive error, anterior chamber depth (ACD), IOL decentration and tilt, corneal endothelial cell density (CECD) and postoperative complications were recorded.

Background: Knotted suture bridge repair (KSBR) has been widely proven to be an effective method for rotator cuff repairs. However, the occurrence of type 2 failure after suture bridge repair remains a frequent problem because of the stress concentration and disturbance of tendon perfusion in the medial row. The authors have developed the H-loop knotless double-row repair (HLDR) to counteract these problems. Read More

Regardless of the reconstruction surgery used, the fundamental concepts of visceral reconstruction are based on the vascular support needed for the substituting graft. The vascular factor is the main element of any reconstruction technique, as an underlying condition for the visceral material stretch and, along with other factor, for the suture safety. In the case of the stomach, a consistent vascular flow and the minimal vascular anatomy variations are the first theoretical argument. Read More

Background: We have previously reported the 1-year outcomes of arthroscopic suprapectoral biceps tenodesis (ASPBT) versus open subpectoral biceps tenodesis (OSPBT) for the management of long head of the biceps tendon (LHBT) pathology. While patients had similar 1-year biceps muscle strength and pain, longer-term functional outcomes are unknown.

Purpose: To directly compare clinical outcomes of ASPBT versus OSPBT with interference screw fixation, distal to the bony bicipital groove, at a minimum of 2 years' follow-up. Read More

Managing complex inguinal hernias has been a constant challenge for surgeons and its treatment is not without challenges with the routine current techniques. Complex inguinal hernias especially recurrent have been managed by the Rives-Stoppa technique which is an established suture-less, tension-free, and absolute method of treatment with minimal recurrence rates. Traditionally, this surgical technique is most indicated in recurrent inguinal hernias, but we aim to assess the usefulness of this procedure for the treatment of complex inguinal hernias in individuals presenting for the first time.

Background: Tracheal resection and anastomosis surgery is a safe operation and is used to treat various benign and malignant diseases of the trachea. However, tracheal stenosis is among the main anastomotic complications following this procedure. Surgeons use both the continuous and the interrupted suture techniques for tracheal anastomosis, but contradicting results in each technique's complications have been reported in various studies.

Purpose: To analyze the literature to compare outcomes and complications following primary lateral ankle ligament repair compared with lateral ankle ligament reconstruction and the suture tape augmentation in patients with lateral ankle instability.

Methods: Following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) criteria, a systematic literature review using the PubMed/Ovid Medline database was performed (October 11, 1947, to October 1, 2019). Clinical trials that included all the following criteria were considered eligible; published in the English language; patients undergoing primary lateral ankle repair or reconstruction with/without autograft or allograft (anterior talofibular ligament, anterior talofibular ligament + calcaneofibular ligament) or suture tape augmentation; a follow-up at least 1 year; reported least 1 of the measured outcomes (The American Orthopaedic Foot Ankle Score, Karlsson Score, return to sport [RTS], complications, skin wound complications, reoperation).

Long head biceps tendon pathology is a substantial contributor to anterior shoulder pain and often requires surgical intervention to offer a return to normal functionality. Surgical treatment options consist of both open and arthroscopic tenodesis or tenotomy of the long head biceps brachii. Several techniques exist for tenodesis and tenotomy of the biceps, although current debate continues regarding which surgical approach is the optimal intervention for symptomatic bicep pathology.

Glenohumeral bone loss is a significant risk factor for recurrent instability after shoulder dislocation. The Hill-Sachs lesion is an osseous defect of the posterior humeral head that is commonly recognized after anterior shoulder dislocation. Several procedures exist to address humeral-sided bone loss, including soft tissue filling procedures, osteoarticular allografts, bone plugs, rotation osteotomies, and humeral head replacements.

The anterior talofibular ligament (ATFL) is the most frequently injured lateral ligament of the ankle, and up to 20% of patients with ankle sprains may require surgical intervention to correct chronic lateral ankle instability. There has been increased interest in arthroscopic lateral ankle ligament repair techniques to minimize postoperative pain and expedite recovery. Additionally, the use of suture-tape augmentation may allow for improved recovery in those with ATFL reconstruction. Read More

Medial meniscus posterior root tears can lead to rapid progression of knee arthritis because of loss of the stress distribution function of the meniscus. Medial meniscus root repair can restore stress distribution and improve clinical outcome. In cases of medial meniscus root tears with meniscal extrusion, centralization may help reduce extrusion and protect the root repair. Read More

Peripheral nerve mapping tools with higher spatial resolution are needed to advance systems neuroscience, and potentially provide a closed-loop biomarker in neuromodulation applications. Two critical challenges of microscale neural interfaces are 1) how to apply them to small peripheral nerves, and 2) how to minimize chronic reactivity. A flexible microneedle nerve array (MINA) is developed, which is the first high-density penetrating electrode array made with axon-sized silicon microneedles embedded in low-modulus thin silicone.
