Modified S1 Pedicle Subtraction Osteotomy.

Surgical technique video. To report a surgical technique to revise patients with previous fusions at L4-S1 leading to an iatrogenic flat back and sagittal imbalance using L5-S1 transforaminal interbody fusion combined with a small S1 corner osteotomy. This is a case of a woman (51 y old) with a history of multiple lumbar surgeries, severe back pain, sagittal imbalance, and loss of lordosis. We describe a feasible revision technique in a complex patient with the goal of attaining optimal distribution of lumbar lordosis and sagittal balance through a modified S1 pedicle subtraction osteotomy, and the use of an interbody cage to enhance the fusion rate and facilitate closure of the 3-column osteotomy. The preoperative patient lordosis angle of 31 degrees at L1-L4 and 16 degrees at L4-S1 became 12 degrees at L1-L4 and 44 degrees at L4-S1 postoperatively. The combination of L5-S1 transforaminal interbody fusion and S1 corner osteotomy is a feasible technique for the restoration of lumbar lordosis in patients with previous fusion and consequent loss of lordosis.

Scapholunate Ligament Reconstruction With Internal Brace Augmentation Techniques for Chronic Scapholunate Dissociation: A Clinical Follow-up Study.

The scapholunate ligament is the most important stabilizer of the scapholunate articulation. The management of chronic irreversible injuries of this ligament in the absence of preexisting arthritis of the wrist joint remains controversial. Recently, surgeons introduced a novel surgical technique using an internal brace (IB). Several biomechanical studies on this technique have been conducted using cadavers; however, very few studies have discussed the results in detail in actual clinical practice. Therefore, herein, we investigated the radiological and functional results of patients who underwent IB augmentation as a treatment for chronic scapholunate dissociation. This retrospective study was conducted from April 2018 to May 2022. Twenty-two patients with chronic scapholunate dissociation were treated using the IB augmentation technique, of whom 17 were followed-up for at least 1 year. Radiological results, including scapholunate distance, scapholunate angle, and radioscaphoid angle, were collected. Furthermore, clinical parameters, such as the visual analog scale (preoperative and at final follow-up), the Disabilities of the Arm, Shoulder, and Hand scores (preoperatively and at 3, 6, and 12 months postoperatively), and Mayo wrist scores (preoperative and at final follow-up), were measured. The scapholunate distance increased significantly in the affected wrist compared to the unaffected wrist, which improved after reconstruction in all wrist positions ( P < 0.05). Compared to the unaffected wrist, the scapholunate angle increased significantly in all positions ( P < 0.05) except for extension ( P = 0.535) and improved after reconstruction in all wrist positions. The radioscaphoid angle significantly increased compared to the angle of the unaffected wrist in all positions ( P < 0.05) except for extension ( P = 0.602) and clenched fist ( P = 0.556). This angle improved after reconstruction in all wrist positions except for extension ( P = 0.900). The visual analog scale score (7-2, preoperatively and at final follow-up) and Mayo wrist score (53-82, preoperatively and at final follow-up) improved after surgery. The Disabilities of the Arm, Shoulder, and Hand scores also improved after surgery (68, 53, 30, 7, preoperatively and at 3, 6, and 12 months postoperatively). This study revealed that scapholunate ligament reconstruction using an autologous tendon and suture tape is a good reconstruction technique that can improve clinical symptoms and radiographic parameters with a shorter operation time and fewer complications than other reconstruction methods.

Surgical Management of Massive Irreparable Cuff Tears/Management of Rotator Cuff Disease: Interpositional Graft for Irreparable Posterosuperior Rotator Cuff Tears.

Increasingly, massive irreparable rotator cuff tears present a treatment challenge due to their high re-tear rates. The reparability of such tears depends on factors like tear size, the number of involved tendons, tendon retraction extent, muscular atrophy, fatty infiltration, and the presence or absence of arthritis. There are non-surgical and several surgical treatment options described each with their specific indications, contraindications, pros, and cons. Bridging reconstruction restores the superior rotator cuff tissue and arrests humeral head superior migration. The purpose of his review is to explore the existing literature on interpositional graft mechanics, indications, surgical technique, and clinical outcomes. It aims to understand how these parameters can facilitate the incorporation of bridging reconstruction using interpositional grafts into a surgeon's practice for managing massive irreparable rotator cuff tears. Interpositional grafts for irreparable massive rotator cuff tears can either be auto-, allo-, xenografts, or synthetic material and are best suited for patients who are relatively younger, no glenohumeral arthritis, and minimal to no fatty infiltration and muscle atrophy. Short to medium term outcome studies available report good functional, clinical, and radiological improvements with bridging reconstruction utilizing acellular dermal matrix allograft. Interpositional grafts for management of irreparable posterosuperior cuff tears provides improved clinical and radiological outcomes with minimal complications and thus a viable and valuable surgical technique for a shoulder surgeon's armamentarium.

An Evaluation of Autologous Fat Injection as a Treatment for Velopharyngeal Insufficiency: A Review and Integrated Data Analysis.

Velopharyngeal insufficiency (VPI) is a condition characterized by incomplete separation of the oral and nasal cavities during speech production, thereby leading to speech abnormalities and audible nasal emissions. Subsequently, this adversely impacts communication and potentially interpersonal social interactions. Autologous fat grafting (AFG) to the velopharynx, a minimally invasive technique, aims to improve oronasal separation by providing bulk and advancing the posterior pharyngeal wall toward the soft palate. Despite its potential, the relative novelty of AFG in treating VPI has resulted in reporting of inconsistent indications, varied surgical techniques, and mixed outcomes across existing literature. This systemic review examined the evidence of AFG for VPI treatment over the past decade (2013-2023). A thorough search across five electronic databases yielded 233 studies, with 20 meeting the inclusion criteria (e.g., utilized fat injection as their selected VPI treatment, conducted study in human subjects, did not perform additional surgical procedure at time of fat injection). Selected studies encompassed patient and surgical intervention characteristics, perceptual speech assessment (PSA) scores, gap sizes, nasalance measurements, and complications. The majority of patients had a prior cleft palate diagnosis (78.2%), in which nasoendoscopy was the prevalent method for visualizing the velopharyngeal port defect. Fat harvesting predominantly occurred from the abdomen (64.3%), with an average injection volume of 6.3 mL across studies. PSA and subjective gap size scores were consistently higher preoperatively than postoperatively. PSA score analysis from seven studies revealed significant and sustained improvements postoperatively. Gap size score analysis from four studies demonstrated similar preoperative and postoperative differences. Complications were reported in 17 studies, yielding a 2.7% summative complication rate among 594 cases. Autologous fat grafting has emerged as a minimally invasive, safe, and effective treatment for mild to moderate VPI. However, challenges remain because of variability in patient selection criteria, diagnostic modalities, and outcome measurements. This review underscores the need for randomized control trials to directly compare AFG with standard-of-care surgical interventions, providing more conclusive evidence of its clinical efficacy.

Management of Anterior Cruciate Ligament Tears in Skeletally Immature Patients.

Anterior cruciate ligament (ALC) tears are increasingly common in skeletally immature patients, as more children and adolescents participate in intensive sports training and specialization at increasingly younger ages. These injuries were historically treated nonoperatively, given concerns for physeal damage and subsequent growth disturbances after traditional ACL reconstruction techniques. However, there is now sufficient data to suggest superior outcomes with operative treatment, specifically with physeal-sparing and physeal-respecting techniques. This article reviews considerations of skeletal maturity in patients with ACL tears, then discusses surgical techniques, with a focus on their unique indications and outcomes. Additional surgical adjuncts and components of postoperative rehabilitation, which may reduce retear rates, are also considered. Current research shows favorable patient-reported outcomes and high return-to-sport rates after ACL reconstruction in skeletally immature patients. Graft rupture (ACL retear) rates are low, but notably higher than in most adult populations. Historically, there has been insufficient research to comprehensively compare reconstruction techniques used in this patient population. However, thoughtful systematic reviews and multicenter prospective studies are emerging to address this deficit. Also, more recent data suggests the addition of lateral extra-articular procedures and stringent return-to-sports testing may lower retear rates. Physeal-sparing and physeal-respecting ACL reconstructions result in stabilization of the knee, while respecting the growth remaining in children or skeletally immature adolescents. Future research will be essential to compare these techniques, given that more than one may be appropriate for patients of a specific age and skeletal maturity.

Cytoreductive Surgery Plus Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Patients with Advanced Ovarian Cancer: A 2-year Survival Analysis Study

Background: During the last few years, Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy (HIPEC) has entered the national comprehensive cancer network guidelines as a new protocol for improving patients’ outcomes. However, there is no consensus on its long-term efficiency, and it still is under debate. Objectives: This study aims to evaluate the effectiveness of Cytoreductive Surgery Plus hyperthermic intraperitoneal chemotherapy in patients with advanced ovarian cancer in Iran. Method: Thirty patients with Stage IIIc and IV advanced ovarian cancer underwent cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy at Jam Hospital with a fixed surgical team in Tehran, Iran, from 2019 to 2021. Fourteen patients were new cases, and sixteen of them were recurrent cases. At the end of cytoreductive surgery, by using a hyperthermic intraperitoneal chemotherapy device, Cisplatin was circulated in the peritoneal cavity for 90 minutes at a dose of 80-100 mg/ m2 at 43°C. Results: Among 30 patients with 54.97±10.74 years of mean age, the mean overall survival was 564.967 days, and 2-year survival rates were 66.7%. According to Fisher's exact test, there was a statistically significant relationship between disease-free after surgery and mortality rate (p=0.00). However, there was no statistically significant relationship between recurrence after surgery and mortality rate (p=0.093). Conclusion: Based on these findings, cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy had a survival rate of 66.7% within two years in advanced ovarian cancer patients. However, to achieve better results, careful selection of patients and complete cytoreductive surgery should be performed.

Mixed Endometrioid Clear Cell Carcinoma of the Ovary: A Case Report

Background: Despite the high percentage of pure forms of epithelial ovarian cancers (EOC), mixed epithelial cancer of the ovary is extremely rare and accounts for less than 1% percent of all epithelial ovarian cancers. Because of the low prevalence; there are only a few cases of mixed epithelial cancers published in the literature. This study presents the case of a mixed endometrioid (EC)/clear cell carcinoma (CCC), diagnosed in a woman with a complaint of low back pain and a history of infertility. Case Report: We report the case of a 35-year-old woman who came to our clinic complaining of progressive back pain and a history of infertility. Imaging showed a left ovarian mass that was compatible with malignant tumors. The patient underwent open surgery and a frozen section evaluation of the tumor was done during the operation. The pathology result demonstrated mixed CCC/EC histology in the left ovary. We decided to perform a total abdominal hysterectomy as well as right salpingooophorectomy, omentectomy, bilateral pelvic lymphadenectomy, and para-aortic lymphadenectomy. Adjuvant chemotherapy was administrated postoperatively. Conclusion: Although epithelial cancers account for more than 90% of all ovarian cancers (OC), developing mixed forms of epithelial cancers is extremely rare, and there are little data available in the literature about their presentation and histopathological features. The main purpose of this article was to report a mixed CCC/EC and to discuss different aspects of this rare histologic type of OC. More research is needed to determine metastatic potential as well as the likelihood of recurrence of these unique neoplasms.

Why Deep Plane Face and Neck Lifting Results in the Maximum Short- and Long-term Results? My Primary Choice for Rhytidectomy in My Practice.

I converted to the extended deep plane facelift and neck lift with a shorter skin flap elevation in the face to achieve a more complete release of the facial ligaments to obtain more mobilization of the skin/superficial musculoaponeurotic system composite flap, and a more medial suspension resulting in improved correction of the midface, nasolabial fold, marionette fold and jowl. Treatment of the deep neck structures allowed for more refinement of the submentum in the deep neck lift procedures as well. In this article, we shall review the surgical technique of the deep plane facelift and neck lift as well as postoperative management pearls, the management of complications from the procedure, and the incorporation of ancillary procedures.

Optimizing Surgical Outcomes and the Role of Preventive Surgery: A Scoping Review.

Plastic and reconstructive surgeons are often presented with reconstructive challenges as a sequela of complications in high-risk surgical patients, ranging from exposure of hardware, lymphedema, and chronic pain after amputation. These complications can result in significant morbidity, recovery time, resource utilization, and cost. Given the prevalence of surgical complications managed by plastic and reconstructive surgeons, developing novel preventative techniques to mitigate surgical risk is paramount. Herein, we aim to understand efforts supporting the nascent field of Preventive Surgery, including (1) enhanced risk stratification, (2) advancements in postoperative care. Through an emphasis on four surgical cohorts who may benefit from preventive surgery, two of which are at high risk of morbidity from wound-related complications (patients undergoing sternotomy and spine procedures) and two at high risk of other morbidities, including lymphedema and neuropathic pain, we aim to provide a comprehensive and improved understanding of preventive surgery. Additionally, the role of risk analysis for these procedures and the relationship between microsurgery and prophylaxis is emphasized. (1) medical optimization and prehabilitation, (2) surgical mitigation techniques. Reconstructive surgeons are ideally placed to lead efforts in the creation and validation of accurate risk assessment tools and to support algorithmic approaches to surgical risk mitigation. Through a paradigm shift, including universal promotion of the concept of "Preventive Surgery," major improvements in surgical outcomes may be achieved.

Steel bar penetrating cervical spinal canal without neurological injury: A case report

BACKGROUND We report a rare case of cervical spinal canal penetrating trauma and review the relevant literatures. CASE SUMMARY A 58-year-old male patient was admitted to the emergency department with a steel bar penetrating the neck, without signs of neurological deficit. Computed tomography (CT) demonstrated that the steel bar had penetrated the cervical spinal canal at the C6–7 level, causing C6 and C7 vertebral body fracture, C6 left lamina fracture, left facet joint fracture, and penetration of the cervical spinal cord. The steel bar was successfully removed through an open surgical procedure by a multidisciplinary team. During the surgery, we found that the cervical vertebra, cervical spinal canal and cervical spinal cord were all severely injured. Postoperative CT demonstrated severe penetration of the cervical spinal canal but the patient returned to a fully functional level without any neurological deficits. CONCLUSION Even with a serious cervical spinal canal penetrating trauma, the patient could resume normal work and life after appropriate treatment.

Fat or fillers: The dilemma in eyelid surgery

The aging of the periocular region has always aroused great interest. A fresh, young, and attractive sight determined an ever-greater attention to surgical and non-surgical techniques to obtain this result. In particular, the change in the concept of a young look, considered then “full”, led to the increasing use of surgical (fat grafting) or medical (hyaluronic acid) filling techniques. Eyelid rejuvenation became increasingly popular in the field of cosmetic treatments, with a focus on achieving a youthful and refreshed appearance. Among the various techniques available, the choice between using fat grafting or fillers presented a clinical dilemma. In particular, what surgery considered of fundamental importance was a long-lasting result over time. On the other hand, aesthetic medicine considered it fundamental not to have to resort to invasive treatments. But what was the reality? Was there one path better than the other, and above all, was there a better path for patients? The minireview aims to explore the physiopathology, diagnosis, treatment options, prognosis, and future studies regarding this dilemma. We analyzed the literature produced in the last 20 years comparing the two techniques. Current literature reveals advancements in biomaterials, stem cell research and tissue engineering held promise for further enhancing the field of eyelid rejuvenation. The choice between fat grafting and fillers in eyelid cosmetic treatments presented a clinical dilemma. Understanding physiopathology, accurately diagnosing eyelid aging, exploring treatment options, assessing prognosis, and conducting future studies were essential for providing optimal care to patients seeking eyelid rejuvenation.

Ilizarov technique for treating elbow stiffness caused by myositis ossificans: A case report

BACKGROUND Myositis ossificans (MO) is a rare disease involving the formation of bone outside the musculoskeletal system. While surgical intervention is the main treatment approach, preventing recurrence and standardized rehabilitation are also crucial. Here, we present a surgical strategy to prevent the recurrence of MO. CASE SUMMARY A 28-year-old female patient was admitted for the first time for a comminuted fracture of the left olecranon. However, incorrect postoperative rehabilitation resulted in the development of elbow joint stiffness with ectopic ossification, causing a loss of normal range of motion. The patient was diagnosed with MO based on physical examination, X-ray findings, and clinical presentation. We devised a surgical strategy to remove MO, followed by fixation with an Ilizarov frame, and implemented a scientifically reasonable rehabilitation plan. The surgery lasted for 3 h with an estimated blood loss of 45 mL. A drainage tube was placed after surgery, and fluid was aspirated through ultrasound-guided puncture. The patient experienced a significant reduction in joint stiffness after surgery. In the final follow-up at 9 mouths, there was evident improvement in the range of motion of the elbow joint, and no other symptoms were reported. CONCLUSION The Ilizarov frame is an advantageous surgical technique for facilitating rehabilitation after MO removal. It offers benefits such as passive recovery, individualized treatment, and prompt recovery.

РОБОТ-АССИСТИРОВАННЫЕ ОПЕРАЦИИ В ДЕТСКОЙ АБДОМИНАЛЬНОЙ ХИРУРГИИ: ПЕРВОНАЧАЛЬНЫЙ ОПЫТ

Purpose of this research was to apply the possibilities of robot-assisted surgery technology in children with abdominal pathology in terms of assessing feasibility and evaluating postoperative results. Material and methods used: the scientific study was carried out at the Irkutsk Oblast Regional Children's Clinical Hospital (Irkutsk, Russia) in Dec. 2022-June 2023. During this period, 11 robot-assisted procedures were performed on the abdominal organs. The study was conducted within the framework of the Clinical Trials Program for Medical Products approved by the Federal Service for Surveillance in Healthcare of the Russian Federation. All surgical procedures were implemented according to the same principles and patterns that the Authors have gathered previously with the Versius Surgical Robot. In all cases, the three robotic ports were used: a single 12-mm trocar for optics (intervened at the umbilicus) and two 5-mm trocars for robotic arms. Additionally, another 5-mm laparoport was installed for the assistant surgeon to work during the robotic intervention. During the study, patients' perioperative parameters related to data charts, surgical details and both early and long-term outcomes were recorded. Results: the total number of patients involved in robotic interventions on the abdominal organs was 11, 4 (36,4%) boys/7 (63,6%) girls. The mean age at the time of surgery was 10,9±5.1 y/o (Me 12.0 [7.0; 15.0] y/o), mean weight at the time of surgery was 39.7±18.0 kg (Me 43.0 [24.0; 53.8] kg). The distribution of reasons for surgical interventions was as follows: 3 (27,3%) patients with Nissen fundoplication, 3 (27,3%) patients with cholecystectomy, 2 (18,2%) patients with Heller esophagomyotomy with Dor fundoplication, 2 (18,2%) patients with splenic cyst fenestration and a single (9%) patient with enucleation of ovarian teratoma. The mean duration was 100±52.4 min (Me 70.0 [65.0; 122.5] min). None of the operations were accompanied by any intraoperative complications. There were also no conversions into laparoscopic and/or open surgeries. In the long-term period after the operations, the number of significant complications in the form of recurrence of symptoms of the initial disease did not increase, patients showed no digestive problems during the entire follow-up period as well. Conclusion: Russia’s initial experience with robotic-assisted abdominal surgery confirmed that robotics can be safely and effectively used in children. Fundoplication, esophagomyotomy and cholecystectomy are by far the most commonly performed basic interventions in pediatric surgery. Obviously, this is the first stage in the development of robotic abdominal surgery in children hence it would further involve a more complex procedure.

Red line the red line: Optimizing emergency medicine physicians and surgeons collaborative roles on trauma teams.

It has long been the standard for surgical and EM teams to both be present upon patient arrival and work together for the sickest trauma patients, yielding improved outcomes. It is important to dismantle divisive perceptions, confront system constraints, and promote new strategies that optimize the engagement of trauma team members. The focus should be on the patient, whose injury care starts with prevention and extends seamlessly through prehospital, hospital and rehabilitation.The authors address several myths that impact collaborative teamwork among emergency medicine physician and surgeons.Leaders, especially at GME sites, need to foster collaborative relationships, rather than adversarial. The red line mentality is a divisive construct that should be dismantled.

This paper aims to address the key factors influencing the safety of posterior chamber phakic intraocular lens implantation, exploring relevant characteristics, mechanisms, and current challenges. By emphasizing the importance of this surgery and proposing effective measures, it aims to provide guidance for clinical practice, enhance the safety of posterior chamber phakic intraocular lens implantation, and foster the healthy advancement of this surgical technique.

Major liver resections, perioperative issues and posthepatectomy liver failure: A comprehensive update for the anesthesiologist

Significant advances in surgical techniques and relevant medium- and long-term outcomes over the past two decades have led to a substantial expansion in the indications for major liver resections. To support these outstanding results and to reduce perioperative complications, anesthesiologists must address and master key perioperative issues (preoperative assessment, proactive intraoperative anesthesia strategies, and implementation of the Enhanced Recovery After Surgery approach). Intensive care unit monitoring immediately following liver surgery remains a subject of active and often unresolved debate. Among postoperative complications, posthepatectomy liver failure (PHLF) occurs in different grades of severity (A-C) and frequency (9%-30%), and it is the main cause of 90-d postoperative mortality. PHLF, recently redefined with pragmatic clinical criteria and perioperative scores, can be predicted, prevented, or anticipated. This review highlights: (1) The systemic consequences of surgical manipulations anesthesiologists must respond to or prevent, to positively impact PHLF (a proactive approach); and (2) the maximal intensive treatment of PHLF, including artificial options, mainly based, so far, on Acute Liver Failure treatment(s), to buy time waiting for the recovery of the native liver or, when appropriate and in very selected cases, toward liver transplant. Such a clinical context requires a strong commitment to surgeons, anesthesiologists, and intensivists to work together, for a fruitful collaboration in a mandatory clinical continuum.
