Endoscopic Repair of Spontaneous Cerebrospinal Fluid Leaks in the Lateral Recess of the Sphenoid Sinus

Objective This study aimed to assess the effectiveness of 3 endoscopic endonasal approaches for the management of cerebrospinal fluid (CSF) leaks and meningoencephaloceles in the lateral recess of the sphenoid sinus (LRSS). Study Design Retrospective study. Setting University hospital. Methods This study retrospectively reviewed 49 patients with CSF leaks and meningoencephaloceles in the LRSS. Three endoscopic surgical repair approaches were indicated based on 5 different Rhoton’s types of the LRSS. The postoperative symptoms, complications, and follow-up outcomes were investigated and evaluated. Results The success rate of endoscopic surgical repair was 100% at a median follow-up of 75.06 (12-203.4) months. Endoscopic approaches to the LRSS included the prelacrimal recess (PLR) (18.37%), transsphenoidal (18.37%), and transpterygoid approaches (64.26%). All patients in the PLR approach (PLRA) group and most of the patients in the transpterygoid approach group had a full lateral type LRSS. Hypoesthesia and dry eyes were reported in 5 patients (55.56%) and 1 (11.12%) patient, respectively, from the PLRA group and in 6 (19.35%) and 5 (16.12%) patients, respectively, from the transpterygoid approach group. Conclusions Endoscopic closure is a safe and effective method for the treatment of CSF leaks and meningoencephaloceles in the LRSS. The transpterygoid approach and PLRA offer adequate exposure of the LRSS with extensive lateral pneumatization or a full LRSS. The endoscopic route of the PLRA is more direct than that of the transpterygoid approach. Careful preoperative imaging evaluation is crucial while selecting the optimal surgical approach for the repair of a skull base defect.

Endovascular Instead of Open Surgical Repair of Axillosubclavian Artery Injuries: An Evolving Paradigm Shift

Axillosubclavian injuries (ASI) comprise a small proportion of vascular injuries, yet their morbidity and mortality is high. This is often attributable to non-compressible bleeding in the apical thorax, hemodynamic instability, and the anatomically challenging location of these vessels making them difficult to access and control quickly. While the traditional management of ASI was with open surgical repair (OSR), recent years have seen an evolution towards less invasive endovascular repair (EVR). In patients with these injuries, EVR may be a safer alternative that achieves similar immediate results with significantly lower complication and mortality rates than the highly morbid open surgical option. In this article, we review and compare the two approaches, providing an overview of patient selection, anatomic considerations, techniques, postoperative management, and outcomes. With the advent of EVTM and more trauma team members capable of endovascular management of vascular trauma, a paradigm shift towards EVR for ASI is taking place.

Adipose Tissue Uses in Peripheral Nerve Surgery

Currently, many different techniques exist for the surgical repair of peripheral nerves. The degree of injury dictates the repair and, depending on the defect or injury of the peripheral nerve, plastic surgeons can perform nerve repairs, grafts, and transfers. All the previously listed techniques are routinely performed in human patients, but a novel addition to these peripheral nerve surgeries involves concomitant fat grafting to the repair site at the time of surgery. Fat grafting provides adipose-derived stem cells to the injury site. Though fat grafting is performed as an adjunct to some peripheral nerve surgeries, there is no clear evidence as to which procedures have improved outcomes resultant from concomitant fat grafting. This review explores the evidence presented in various animal studies regarding outcomes of fat grafting at the time of various types of peripheral nerve surgery.

Surgical Repair of Acquired Oronasal Fistulas Secondary to Periodontal Disease in Dogs Using a Flexible Bone Membrane: A Case Series

Oronasal fistulas are sequelae to periodontal disease in dogs. Previous case series have described the use of auricular cartilage as a type of membrane to help with surgical repair of oronasal fistulas. This case series explores the use of a commercially available flexible bone membrane in the surgical repair of ten acquired oronasal fistulas in dogs. The use of the flexible bone membrane did not necessarily improve the surgical outcomes in these cases; however, larger controlled trials are necessary to further evaluate its use.

Transumbilical Repair for Umbilical Hernia: A New Technique

Although there are many reports on surgical repair for umbilical hernia, there is no standard procedure at present. Since 2012, we have performed surgery with transumbilical repair using an original procedure. With this procedure, a longitudinal incision is made in the umbilicus, and the fascial defect is closed. Excess skin is excised at a fixed length. The fascia and dermis are sutured vertically over a length of 15 mm. A total of 424 patients with pediatric umbilical hernia who underwent this procedure between September 2012 and December 2020 were reviewed. The mean operative duration was 52 minutes. All patients were followed up to 6 months after surgery. Postoperative complications included infection in 15 patients and wound granulation in 5 patients. The morphology of the umbilicus is natural and satisfying. We conclude that this procedure is safe and simple and the results are satisfactory.

Review of Traumatic Duodenal Injuries: Etiology, Diagnosis, and Management

Traumatic duodenal injuries are rare and often challenging to diagnose and treat. Management of these injuries remains controversial and continues to evolve. Here, we performed a review of the literature and guidelines for the diagnosis and management of traumatic duodenal injuries. A common recommendation in more recent literature is primary, tension-free repair of duodenal injuries when possible if surgical repair is necessary. Conversely, if duodenal injuries are unamenable to primary repair, more complex procedures such as Roux-en-Y duodenojejunostomy or pancreaticoduodenectomy may be necessary. Regardless of injury grade or type of surgical repair, the literature continues to support wide extraluminal drainage. Over time, the management of complex duodenal injuries has evolved to favor simple primary repair whenever possible. According to recent studies, more complex procedures are associated with higher rates of post-operative complications and should be reserved for severe injuries when primary repair is not possible.

AAA Revisited: A Comprehensive Review of Risk Factors, Management, and Hallmarks of Pathogenesis

Despite declining incidence and mortality rates in many countries, the abdominal aortic aneurysm (AAA) continues to represent a life-threatening cardiovascular condition with an overall prevalence of about 2–3% in the industrialized world. While the risk of AAA development is considerably higher for men of advanced age with a history of smoking, screening programs serve to detect the often asymptomatic condition and prevent aortic rupture with an associated death rate of up to 80%. This review summarizes the current knowledge on identified risk factors, the multifactorial process of pathogenesis, as well as the latest advances in medical treatment and surgical repair to provide a perspective for AAA management.

Open repair for thoracoabdominal aortic aneurysms precipitated by chronic aortic dissection

Chronic dissection of the thoracoabdominal aorta may require surgical repair for aneurysm, malperfusion, or rupture. Endovascular repair is made difficult by a noncompliant dissection septum, visceral vessels arising from different lumens, and the common use of diseased aortic landing zones. Thus, open repair remains the gold standard in terms of favorable outcomes and durability. During thoracoabdominal aortic repair, we use a multimodal strategy to prevent spinal cord and visceral or renal artery ischemia; key modalities include cerebrospinal fluid drainage, left heart bypass with and without visceral protection, cold renal protection, and aggressive reimplantation of intercostal or lumbar arteries. Patients with chronic dissection require lifelong surveillance, as there is a significant risk for subsequent intervention on unrepaired aortic segments.

Treatment of subacute/chronic ECU tendinopathy using wrist arthroscopy and open surgical repair

Purpose To report the arthroscopic and clinical findings of patients with extensor carpi ulnaris (ECU) tendinopathy treated with wrist arthroscopy and open surgical repair. Methods We retrospectively reviewed the medical records of seven patients with chronic ECU tendinopathy who were treated with diagnostic wrist arthroscopy and open surgical repair between 2010 and 2017. Seven cases diagnosed with ECU tendinopathy had undergone open procedure for the ECU tendinopathy, as well as wrist arthroscopy in the same session. Any pathology of the triangular fibrocartilage complex (TFCC) diagnosed by wrist arthroscopy were treated simultaneously with open procedure for the ECU tendinopathy. The functional outcome was evaluated by comparing the preoperative and final follow-up values of range of motion (ROM), grip strength, visual analog scale (VAS) for pain, modified Mayo wrist score and quick disabilities of the arm, shoulder, and hand (DASH) score. Results TFCC tears were identified in four patients of which repair was performed concomitantly. The average follow-up period was 39 months (range, 25–49 months). At the final follow-up, all the outcomes including average VAS score (6.4→1), the ROM (173→192°), quick DASH score (42.5→18.2), and modified Mayo wrist score (48.6→79.3) improved significantly. Conclusion When treating patients with ECU tendinopathy, the possibility of TFCC combined injury should always be considered. If surgical treatment is planned, we suggest a wrist arthroscopy for more accurate diagnosis an intra-articular pathology, particularly for patients whose MRI findings suggest a degenerative tear or degeneration at the periphery of the TFCC. Additionally, if ECU and DRUJ stability is obtained by repair or reconstruction of the concurrent pathologies in the ECU subsheath, TFCC and other intra-articular structures, the results will be favorable.
