Clinical Spectrum and Perspective in Bilateral Acute Retinal Necrosis: Systematic Review

Bilateral acute retinal necrosis (BARN) represents a broad ophthalmological field of severe retinal pathologies associated with poor visual prognosis and blindness. The purpose of this review is to examine the clinical spectrum in detail over the past few years, exploring laboratory and instrumental diagnosis, and providing useful and up-to-date guidance in this field. A systematic review of this field has been performed through the PRISMA guidelines, searching in the PUBMED database. Serological laboratory tests on blood or polymerase chain reaction (PCR) on aqueous humor or vitreous samples are crucial to identifying the underlying cause and choosing the timeliest strategic treatments. Often, the main cause remains herpesviruses, with Varicella zoster (VZV) predominating over the others. There are also other causes that one needs to be carefully aware of. Anatomical and functional recovery is unfavorable if they are not individuated in a quick time. Early diagnosis and timely treatment offer a better chance of visual improvement and the avoidance of complications. Complications worsen the visual prognosis over months and may require a surgical approach.

Reconstruction of Complex Oral and Maxillofacial Defects After Oral Cancer Resection With Individualized Anterolateral Thigh Multiple Paddle Flaps.

This study aimed to use reconstructive methods for complex oral and maxillofacial defects, explore their feasibility, and evaluate the efficacy of defect reconstruction using anterolateral thigh (ALT) multiple paddle flaps. The authors performed a retrospective case series of 33 patients who underwent oral and maxillofacial defect reconstruction using the ALT multiple paddle flaps. The design and harvest of the flaps, methods for defects reconstruction, and reconstructive efficacy are described. All 33 patients were men, with a mean age of 49.5 years. Of the flaps, triple skin paddles plus muscle paddles were included in 3 cases, triple skin paddles were included in 1 case, 2 skin paddles plus muscle paddles were included in 29 cases. The skin paddles measured 3×5cm to 10×16cm. Postoperatively, all flaps survived completely. Parotid salivary fistula and orocutaneous fistula occurred in 1 patient of each, thigh wound infection and effusion occurred in 1 and 2 patients, respectively. All patients were followed up for ~2 to 93 months; most patients' oral functions and appearance were acceptable, and thigh motor dysfunction was not observed. With separate skin paddles for defects of different positions, individualized muscle flap for dead spaces, combination of different skin paddles for larger defects, effective reduction or avoidance of wound complications, and acceptable donor site morbidity, the ALT multiple paddle flaps are an ideal candidate for complex oral and maxillofacial defects reconstruction.

Metaizeau technique in stabilizing Monteggia equivalent 1b associated proximal radial physeal injury in a rural setting: a case report

Introduction: The Monteggia equivalent type 1b fracture, consisting of an ulnar shaft fracture and radial head dislocation, is a rare condition first described by Giovanni Battista Monteggia. The Metaizeau technique, emphasizing percutaneous intramedullary fixation to preserve bone healing and prevent growth plate damage, has gained prominence in managing these fractures. Case report: A 10-year-old boy presented with left forearm pain, swelling, and deformity following a fall while playing football. X-rays revealed a proximal fourth ulnar fracture with dorsal and lateral angulation, along with a proximal radial metaphyseal fracture showing anterior rotation and physeal extension. This fracture pattern resembled a Monteggia fracture type III but differed in the lateral proximal radial disruption via a Salter–Harris type II fracture rather than radial epiphysis dislocation. Satisfactory reduction achieved for ulna was managed with standard nailing system but could not be achieved for radial physeal injury, which was managed with Metaizeau technique. Discussion: Type 1b Monteggia equivalents involving a Salter–Harris type 2 fracture of the proximal radius with an associated proximal ulnar fracture, adherence to Monteggia fracture reduction principles is vital. Closed reduction and internal fixation are preferred treatments, with the Metaizeau technique offering advantages such as minimal invasiveness and avoidance of implant-related complications. The Metaizeau technique is particularly beneficial for displaced radial neck fractures in children, providing stable fixation while preserving the fracture environment necessary for optimal healing. Conclusion: In cases of Monteggia fracture equivalents, most proximal radial fractures typically reduce to an acceptable level following ulnar reduction. However, proximal radial physeal fractures may require specific attention to achieve satisfactory reduction. The Metaizeau technique, commonly employed in the management of isolated radial neck fractures, can be utilized to achieve this reduction to an acceptable level.

Total extra-peritoneal approach to radical cystectomy with ureterostomy: A novel technique for the elderly and frail

ObjectivesRadical cystectomy with urinary diversion is the gold standard treatment for bladder cancer (high-risk/muscle invasive). The transperitoneal approach is associated with significant gastrointestinal complications like ileus. In the elderly and frail with a single functional kidney, we describe an extraperitoneal technique of radical cystectomy, with a ureterostomy, to be performed without general anesthesia. Materials and methodsThe elderly, frail, and high-risk candidates for general anesthesia, with a prior history of nephroureterectomy with a second primary muscle-invasive bladder cancer, were chosen. All patients underwent the described procedure under combined spinal and epidural anesthesia. The posterior dissection was retrograde, caudal to cranial, with the peritoneum being opened only for resection of the dome. A cutaneous ureterostomy was fashioned on the side of the functional kidney. Peri-operative parameters were assessed for early recovery in this high-risk group. ResultsThe mean age was 82 years (range: 73–91), with Charleson Comorbidity Index 5, and were all deemed unfit for neoadjuvant chemotherapy. With a median duration of 127.5 minutes, an average blood loss of 225ml, and no patient requiring general anesthesia; early ambulation, early return of bowel function, and a lesser hospital stay (7 days) with minimal morbidity were achieved. Negative surgical margins were achieved in all cases, with a mean harvest of 29 lymph nodes. Only 1 patient developed stomal stenosis. The cause-specific survival (CSS) is 100% at 2 years. ConclusionsThe highlighting features are the early return of bowel function (flatus passage on day 1) and the avoidance of the cardio-pulmonary complications of general anesthesia. The extraperitoneal cystectomy offers a promising alternative in this select group and warrants further studies to extrapolate this technique for bilateral urinary drainage.

The Oncologic Value of Transoral Resection in Early-Stage Laryngeal Squamous Cell Carcinoma of the Glottis: A Retrospective Study.

Background and objective The treatment of early-stage laryngeal glottic cancer involves surgery or radiotherapy, and both have similar survival rates. However, discrepancies between systematic reviews in the literature point towards the continuous need for more data. In this study, we aimed to investigate the oncologic value of surgery at an ENT university department of a tertiary hospital in Greece. Materials and methods Patients with T1or T2laryngeal squamous cell carcinoma of the glottiswho underwent transoral tumor resection between April 2014 and September 2021 at the hospital were deemed eligible for this study. Disease-free survival (DFS), local control rate (LCR), overall survival (OS), and laryngeal preservation were assessed. Results We enrolled 43 subjects with a median age of 67 years (range: 46-84 years). An overwhelming majority of the subjects were men (39/43). The most common stage was T1a(22/43 subjects). OS was 74 months and DFS was 67 months. We noted local recurrence in 7/43 subjects. Three subjects passed away after five years of follow-up. Eventually, total laryngectomy was performed in 4/43 subjects, two of whom initially suffered from a T2glottic carcinoma. Conclusions Our results align with the findings of the systematic reviews supporting high survival rates, laryngeal preservation, and avoidance of radiotherapy complications observed after transoral surgery for early-stage laryngeal glottic carcinoma.

“Effectiveness of Topical Vs Retrobulbar Anesthesia in Cataract Surgery”

Introduction: Local anesthesia has become preferable to general anesthesia for cataract surgery due to improvements in techniques and instrumentation. The advantages of local anesthesia are well known and include more rapid ambulation, the ability to perform the procedure as an outpatient, avoidance of complications of general anesthesia, and quicker surgery. This study aimed to evaluate and compare the efficacy of topical and retrobulbar anesthesia for cataract surgeries. Methods: This was a retrospective observational study and was conducted in the Department of Anaesthesia, analgesia and Intensive Care Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period from July, 2022 to August, 2023. In our study, we included 60 patients who were undergoing cataract surgery. Patients were divided into two groups – Group A (Patients who received topical anesthesia) and Group B (Patients who received retrobulbar anesthesia. Result: The mean age of study patients was 73.4 ± 8.9 and 74.2 ± 7.4 in Groups A and B respectively. The mean Pain score was 0.87 ± 1.41 and 0.74 ± 1.70 in Groups A and B respectively. The most common preoperative risk factor was exfoliation syndrome (40% in group A and 30% in group B). Twenty-eight patients (93%) in the topical anesthesia group and 60% in the retrobulbar anesthesia group reported no pain at all. Conclusion: In conclusion, topical anesthetic, as opposed to retrobulbar anesthesia, offers the surgeon good surgical conditions and comfortable operating circumstances for the patient, even in challenging instances with related ocular comorbidities.

Novel technique of switching TIVA and sevoflurane during epilepsy surgery for combined intraoperative motor evoked potentials monitoring and electrocorticography: an illustrative case report

BackgroundDuring epilepsy surgery, it is equally important to record electrocorticography (ECoG) for detecting epileptogenic activity and guiding brain resection, and to evaluate neuromonitoring data, particularly motor evoked potentials (MEP), for avoidance of postoperative neurological complications. However, sevoflurane, which is commonly used during recording of ECoG, may attenuate the MEP response. It enforces anesthesiologists and neurosurgeons to select one anesthetic agent over another, facilitating either ECoG or MEP monitoring.Case presentationIn the presented case of a 20-year-old man, who underwent surgery for temporal lobe epilepsy, a novel technique of neuroanesthesia was introduced, integrating initial induction of the total intravenous anesthesia (TIVA) with propofol (effect-site concentration, 2.3–3.0 μg/ml), its subsequent switching to sevoflurane (end-tidal concentration, 2.5%) for ECoG recording, and further change back to TIVA for MEP monitoring during brain resection.ConclusionsIntraoperative switch of anesthetic agents according to specific intraoperative requirements may be useful for cases of brain surgery requiring both ECoG recordings and MEP monitoring.

Aortic Valve-in-Valve Procedures: Challenges and Future Directions.

Aortic valve-in-valve (ViV) procedures are increasingly performed for the treatment of surgical bioprosthetic valve failure in patients at intermediate to high surgical risk. Although ViV procedures offer indisputable benefits in terms of procedural time, in-hospital length of stay, and avoidance of surgical complications, they also present unique challenges. Growing awareness of the technical difficulties and potential threats associated with ViV procedures mandates careful preprocedural planning. This review article offers an overview of the current state-of-the-art ViV procedures, with focus on patient and device selection, procedural planning, potential complications, and long-term outcomes. Finally, it discusses current research efforts and future directions aimed at improving ViV procedural success and patient outcomes.

Changing treatment of hip fractures in Finland

IntroductionHip fracture treatment should be as standardized and effective as possible, with emphasis on fast recovery and avoidance of complications, especially those leading to reoperations. There is accumulating evidence regarding the optimal treatment of hip fractures but reports of whether this has influenced treatment in the clinical setting are sparse. The objective of this study was to determine the trends of hip fracture incidence and treatment in Finland, with special regard to how we treat older patients compared to younger ones.Materials and methodsAll operatively treated hip fractures in Finland between 1997 and 2018 were identified from a national administrative register. The incidence of these fractures and operations performed to treat them were calculated based on the adult population size.ResultsApart from a decline in the elderly age groups during the first half of the study period, the incidence of hip fractures remained relatively constant. However, the incidences of different operations changed significantly. In treatment of femoral neck fractures from 1997 to 2018, the incidence of cemented hemiarthroplasty (HA) increased from 41.1 to 59.9 per 100,000 person-years (105) and hybrid total hip arthroplasty (THA) from 0.56 to 5.93 per 105, while the incidence of internal fixation (IF) decreased, for instance screw fixation from 12.5 to 2.7 per 105. The incidence of cementless HA decreased from 13.3 to 1.2 per 105. These changes were much more pronounced in the elderly population and there was a statistically significant difference in the proportion of patients aged > 59 treated with cemented HA and IF in 1997 compared to 2018. For trochanteric and subtrochanteric fractures, treatment with intramedullary nails replaced extramedullary devices as the most common treatment method.ConclusionsThe changes in treatment methods in Finland correspond to the increasing knowledge available about the optimal treatment of hip fractures and global treatment trends.

Serial dilation to enable ulnar artery access for endovascular neurointervention: Technical report and systematic review of the literature

BackgroundFor rare neuro-endovascular cases in which transfemoral access is not feasible and the palmar circulation is insufficient for radial artery access, ulnar artery access may be considered. Materials and methodsMechanical thrombectomy via ulnar artery access was performed to preserve the dominant radial artery. The ulnar artery was serial dilated to 7-French with microdilator. Angiography was performed using a diagnostic catheter. The sheath was exchanged for a guide catheter, and a triaxial system was inserted. A mechanical thrombectomy was performed. The systematic literature review included all studies pertaining to techniques for ulnar artery access for neurointervention in the last 20 years (2003–2023) published in the PubMed, Web of Science, and Embase databases. Results67-year-old male developed left MCA syndrome in the setting of an infected abdominal aortic endograft. A transfemoral approach was ruled out due to concern for crossing the infected endograft. Allen test and ultrasound demonstrated that the right radial artery was of adequate size for access, but the ulnar artery was insufficient to support the palmar arch. Mechanical thrombectomy resulted in TICI 3 reperfusion. Systematic review of the literature yielded 2 case series and 1 case report of transulnar neurovascular procedures. Access site complications were rare and included 3 access site hematomas and 1 ulnar artery occlusion. ConclusionWe report our technique of serial dilation of the ulnar artery for neuroendovascular procedures and provide a systematic review of the literature for complication avoidance in ulnar artery access.

Endoscopic Transorbital Resection of Temporal Pole Cavernoma: 2-Dimensional Operative Video.

An endoscopic transorbital approach has been recently included in the neurosurgical armamentarium.1 We present a case of a 31-year-old female patient with a history of recent-onset refractory epilepsy related to a left temporal pole cavernoma operated through a superior eyelid endoscopic transorbital approach. The operative video shows the key surgical steps to ensure optimal surgical freedom, adequate exposure, and complete tumor resection.2 The postoperative course was uneventful, and the patient obtained seizure control and good cosmetic results without postoperative complications. The brain computed tomography and MRI showed the size of bone removal and confirmed the complete removal of the lesion, respectively. At 3-month follow-up, the patient is epileptic seizures-free without medications. An endoscopic transorbital approach provides adequate exposure of the temporal pole, allowing safe tumor resection. Complication avoidance encompasses careful dissection of palpebral muscles, dynamic orbital retraction, and neuronavigation guidance; sphenoidal drilling according to key anatomic landmarks (eg, sagittal crest3); and anatomic knowledge of the cavernous sinus and internal carotid artery and its tributaries course from a transorbital perspective4 and reconstruction filling the empty spaces using fat, fascia lata, or dural substitutes. All procedures performed were approved by the ethics committee of both centers and in accordance with Declaration of Helsinki and its later amendments. The patient consented to the procedure and to the publication of her images, and appropriate consent was obtained for publication of cadaveric images.

Repair of bucket handle meniscus tears improves patient outcomes versus partial meniscectomy at the time of ACL reconstruction.

The aim of this study was to examine demographic and surgical factors that influence patient-reported knee function in patients who undergo anterior crucial ligament reconstruction (ACLR) with concurrent bucket-handle meniscal tear (BHMT) procedures. We hypothesized that repair of BHMT in the setting of concomitant ACLR and shorter time from injury to surgery would lead to improved patient-reported outcomes. Forty-one patients (mean age: 28.0 ± 9.8 years, 72% male) with BHMT at the time of ACLR completed the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) via online survey at an average of 15.2 months postop. Patient demographics and surgical characteristics, including time from injury to surgery, were compared between repair (n = 22) and meniscectomy (n = 19) groups using one-way analysis of variances; distributions of sex, graft source, BHMT compartment and zone were compared between groups using χ 2 tests. The association between IKDC-SKF score, demographics and surgical characteristics was evaluated using multivariable linear regression. A priori alpha level was p < 0.05. Meniscal repair and meniscectomy groups differed based on graft source and BHMT zone but not IKDC-SKF score (p = 0.085). Patients undergoing ACLR with autograft (p = 0.003) and with red-red zone BHMT (p < 0.001) more often underwent meniscal repair. The regression model demonstrated longer time from injury to surgery (p = 0.049), red-red tear zone (p = 0.04) and meniscectomy (p = 0.008); these were predictive of poorer IKDC-SKF scores. BHMT repair was more likely performed in ACL autograft and on red-red zone tears. Longer time from injury to surgery is an indicator of poorer IKDC-SKF score, as this may increase the risk of concomitant pathologies. White-white zone BHMTs are associated with better IKDC-SKF scores than red-red zone BHMTs, which may be due to the smaller volume of tissue removed during meniscectomy of white-white zone tears and the avoidance of iatrogenic complications of meniscal repair. Level III, therapeutic study.

Identifying Critical Evidence Gaps in Wound Closure and Incision Management After Total Knee Arthroplasty: Delphi Panel Insights

BackgroundEffective surgical wound management in total knee arthroplasty (TKA) is crucial for optimal healing and patient outcomes. Despite surgical advances, managing wounds to prevent complications remains challenging. This study aimed to identify and address evidence gaps in TKA wound management, including preoperative optimization, intraoperative options, and postoperative complication avoidance. Addressing these issues is vital for patient recovery and surgical success. MethodsThis study used the Delphi method with 20 experienced orthopedic surgeons from Europe and North America. Conducted from April to September 2023, the process involved three stages: an initial electronic survey, a virtual meeting, and a concluding electronic survey. The panel reviewed and reached a consensus on 26 statements about TKA wound management based on a comprehensive literature review. Additionally, the panel aimed to identify critical evidence gaps in wound management practices. ResultsThe panel achieved consensus on various wound management practices but highlighted significant evidence gaps. Consensus was reached on wound closure methods, including mesh-adhesive dressings, skin glue, staples, barbed sutures, and negative pressure wound therapy. However, further evidence is needed to address the cost-effectiveness of these methods and develop best practices for patient outcomes. Identifying these gaps highlights the need for more research to improve TKA wound care. ConclusionsIdentifying major evidence gaps underscores the need for targeted research in TKA wound management. Addressing these gaps is crucial for developing effective, efficient, and patient-friendly wound care strategies. Future research should focus on comparative effectiveness studies and developing guidelines for emerging technologies. Bridging these gaps could improve patient outcomes, reduce complications, and enhance TKA surgery success.

The Safety and Feasibility of Segmental Thoracic Spinal Anesthesia above Umbilicus and Breast Surgery

This study was conducted on 30 patients aged 16 to 70 years with American Society of Anesthesiology (ASA) physical status I, II, and III. Though general anesthesia (GA) is a universally accepted technique for most abdominal surgeries but not free from drawbacks including poly medicine side effects, prolonged recovery time, and unnoticed inadequate pain control, as well as risk to elderly patients with cardiopulmonary conditions, and safety issue limits the usefulness of general anesthesia. Thus, the new technique adopted attracts the attention of anesthesiologists, as thoracic segmental spinal anesthesia (TSSA) for several common surgeries where local anesthetic agents injected intrathecally above the termination of the spinal cord show value in patients with high risk for general anesthesia who need deep analgesia. The types of surgery were periumbilical hernia 7 (23.33%) in both age groups followed by epigastric hernia 8 (26.66%), neoplastic diseases of breast 6 (20%), laparoscopy cholecystectomy 4 (13.33%), open cholecystectomy 5 (16.66%). The analysis of intraoperative and postoperative mean systolic and diastolic arterial pressures (MAP) of patients up to 24 hours was found insignificant (P&gt;0.05). Regarding the intraoperative hemodynamic changes, hypotension occurred in 3 patients and resolved with a single bolus of ephedrine, no tachycardia occurred, while bradycardia in 3 patients (15%). No patients need to be converted to general anesthesia due to inadequate block. On analysis complications, peri-operative or post-operative period showed that shoulder pain was experienced by 2 patients (6.66%) in the younger age group whereas in the older age group, two patients (6.66%) have hypotension and bradycardia was seen in 3 patients (13.33%). No respiratory complications, such as postoperative pneumonia or atelectasis were noted during the hospital stay with TSSA as well and no nausea/vomiting was noted. This study provides only preliminary evidence to support the feasibility and efficacy of segmental thoracic spinal anesthesia to be used effectively for safe anesthetic technique during routine laparoscopic surgery in normal patients as well as co-morbidity patients with stable intraoperative and post-operative hemodynamic and also avoidance of complications of general anesthesia with these benefits, decrease in length of stay in hospital, reduction of postoperative pain, and increased patients satisfaction. Thus, in future the segmental spinal anesthesia may become a good alternative to general anesthesia in normal patients as well as comorbid patients.

Prospective same day discharge instrumented lumbar spine surgery - a forty patient consecutive series.

Outpatient lumbar decompression surgeries have been successfully performed in France for over twenty years, earning acceptance. However, outpatient instrumented lumbar spine procedures and arthroplasties are less documented. This study aimed to evaluate the feasibility, efficiency, and safety of outpatient lumbar instrumented surgery. A prospective single-center study involving three experienced surgeons was conducted from September 2020 to September 2021, with a minimum six-month postoperative follow-up. Inclusion criteria comprised patients aged 18 to 75 eligible for same-day discharge, undergoing single-level lumbar spinal fusion or arthroplasty via anterior or posterior Wiltse approach. The primary endpoint was assessing the percentage of successful outpatient discharges (within twelve hours), with secondary endpoints including perioperative/postoperative complications and discharge pain prescriptions in terms of frequency and severity. Forty patients (mean age: 44 years; 16/24 male/female ratio) underwent surgery, including 18 lumbar arthroplasties, twelve ALIF, and ten TLIF procedures. The majority of surgeries were performed at L4-L5 (18 procedures) and L5-S1 levels (22 procedures). 95% (38/40) of patients were successfully discharged within twelve hours, with only two patients discharged the following day. No postoperative hematomas, serious adverse events, or revision surgeries were noted. 95% of patients were discharged successfully within twelve hours following outpatient lumbar fusion surgery, with a 100% patient satisfaction rate. Specific technical solutions were not necessary, and oral pain relief sufficed. Patient selection and education, including early pain management, played crucial roles in complication avoidance. This study underscores the safety of outpatient instrumented lumbar spine procedures, leading to cost reduction and expedited recovery.

What outcomes do patients value after orthopaedic trauma: A best-worst scaling choice experiment

IntroductionPatient-centered treatment and research should focus on the outcomes that matter to patients. The primary aim of this study was to determine the outcome preferences of patients after musculoskeletal trauma. The secondary aim was to identify discrepancies between outcome preferences of surgeons and patients. MethodsA Best-worst scaling choice experiment survey was administered to patients with operative lower extremity injuries and orthopaedic surgeons who take trauma call. Participants completed 13 choice sets of 3 randomly-ordered outcomes, including: a full recovery (back to normal) without any problems; a problem that requires additional surgery or hospital stay versus medication or treatment in clinic/emergency department; minimal to moderate versus severe pain for 6 weeks; need for crutches/walker versus wheelchair for 6–12 weeks; being unable to work for 6–12 weeks; requiring 2–4 weeks in a facility; a perfect versus poor or worst-possible EuroQol 5 Dimension (EQ-5D) score at 1 year; and death. Within each set, participants ranked their “most-preferred” to “least-preferred” outcomes. Responses were aggregated to calculate the relative importance, or marginal utility, of each outcome stratified by respondent type. ResultsFifty-five patients and 65 surgeons participated. The most preferred outcome for patients and surgeons was a full recovery (back to normal) without any problems, followed by minimal to moderate pain for 6 weeks and a perfect EQ-5D score. The least preferred outcomes were death and the worst EQ-5D score, which had similar marginal utility, followed by a poor EQ-5D score and a problem that needs another surgery or stay at a hospital, which also had similar marginal utility. Surgeons, in comparison to patients, assigned a higher marginal utility to perfect EQ-5D scores at one year (3.55 vs. 2.03; p < 0.0001) and a 2–4 week stay in a facility (0.52 vs. -0.21; p = 0.001), and a lower marginal utility to severe pain for 6 weeks (-0.58 vs. -0.08; p = 0.04) and a poor EQ-5D score (-1.88 vs. -1.03; p = 0.02). ConclusionsA full recovery (back to normal) without any problems was the most-preferred outcome for both patients and surgeons. Patient-centered care and research should focus on both patients’ return to baseline and the avoidance of complications. Level of evidenceN/A

Diagnosis and Management of Thoracic Myelopathy.

Thoracic myelopathy can be a challenging condition to diagnose and treat. Successful outcomes depend on early recondition of the pathology and appropriate surgical referral in cases of progressive neurologic deterioration. The thoracic cord is tethered in kyphosis by the dentate ligaments and contains a tenuous blood supply. These conditions make the thoracic cord particularly susceptible to external compression and ischemic damage. Careful preoperative planning with specific attention to the location and source of thoracic stenosis is critical to successful decompression and complication avoidance. The purpose of this discussion is to outline the common sources of thoracic myelopathy and current recommendations regarding diagnosis and management. The review concludes with an overview of the most up-to-date literature regarding clinical outcomes.

Systematic review on techniques for the creation of pneumoperitoneum in laparoscopic surgeries

Systematic review on techniques for the creation of pneumoperitoneum in laparoscopic surgeries

Multidisciplinary surgical considerations for en bloc resection of sacral chordoma: review of recent advances and a contemporary single-center series.

Contemporary management of sacral chordomas requires maximizing the potential for recurrence-free and overall survival while minimizing treatment morbidity. En bloc resection can be performed at various levels of the sacrum, with tumor location and volume ultimately dictating the necessary extent of resection and subsequent tissue reconstruction. Because tumor resection involving the upper sacrum may be quite destabilizing, other pertinent considerations relate to instrumentation and subsequent tissue reconstruction. The primary aim of this study was to survey the surgical approaches used for managing primary sacral chordoma according to location of lumbosacral spine involvement, including a narrative review of the literature and examination of the authors' institutional case series. The authors performed a narrative review of pertinent literature regarding reconstruction and complication avoidance techniques following en bloc resection of primary sacral tumors, supplemented by a contemporary series of 11 cases from their cohort. Relevant surgical anatomy, advances in instrumentation and reconstruction techniques, intraoperative imaging and navigation, soft-tissue reconstruction, and wound complication avoidance are also discussed. The review of the literature identified several surgical approaches used for management of primary sacral chordoma localized to low sacral levels (mid-S2 and below), high sacral levels (involving upper S2 and above), and high sacral levels with lumbar involvement. In the contemporary case series, the majority of cases (8/11) presented as low sacral tumors that did not require instrumentation. A minority required more extensive instrumentation and reconstruction, with 2 tumors involving upper S2 and/or S1 levels and 1 tumor extending into the lower lumbar spine. En bloc resection was successfully achieved in 10 of 11 cases, with a colostomy required in 2 cases due to rectal involvement. All 11 cases underwent musculocutaneous flap wound closure by plastic surgery, with none experiencing wound complications requiring revision. The modern management of sacral chordoma involves a multidisciplinary team of surgeons and intraoperative technologies to minimize surgical morbidity while optimizing oncological outcomes through en bloc resection. Most cases present with lower sacral tumors not requiring instrumentation, but stabilizing instrumentation and lumbosacral reconstruction are often required in upper sacral and lumbosacral cases. Among efforts to minimize wound-related complications, musculocutaneous flap closure stands out as an evidence-based measure that may mitigate risk.
