Tibial derotational osteotomy for idiopathic tibial torsion: A systematic review of surgical indications based on clinical presentation and measurement technique.

PURPOSE: The aim of this systematic review was to identify the surgical indications of tibial derotational osteotomy (TDO) in patients with idiopathic external tibial torsion (ETT) and identify common measurement thresholds for surgical correction. METHODS: A systematic search of MEDLINE and Embase via Ovid, Cochrane Library via Wiley, Web of Science, Scopus, SPORTDiscus via EBSCOhost, ClinicalTrials.gov, WHO ICTRP and Global Index Medicus databases was performed with search terms reflecting the concepts of idiopathic tibial torsion, TDOs, and surgical indications. Studies reporting surgical indications and measurement methods of idiopathic tibial torsion in patients who underwent TDO were included. Two authors independently screened articles and extracted data that was characterized with descriptive statistics. RESULTS: Seventeen studies were identified for inclusion, with 460 tibias and 351 patients. Nearly all patients who underwent surgery had either anterior knee pain or patellar instability, even if other indications were present. Of all included patients, the most common surgical indications for TDO were anterior knee pain (88%), patellar instability (59%), gait dysfunction (41%) and cosmetic deformity (12%). Twelve studies (71%) cited multiple of these indications as reasons for surgery. On physical exam, tibial torsion was measured most commonly by thigh-foot angle (59%) (TFA) and transmalleolar axis (24%) (TMA). In terms of TFA, the most frequently reported cut-off for ETT was >30° (35%). Computerized tomography (CT) was used by nine studies (53%). The most common CT axes used to measure ETT were the TMA with respect to the posterior tibia condylar axis or the bicondylar tibia axis. CONCLUSION: Anterior knee pain and/or patellar instability are common indications for TDO in patients with idiopathic tibial torsion. Standardized TFA thresholds (>30°) and CT measurement methods (TMA and posterior tibia condylar or bicondylar tibial axis) may help further establish objective surgical indications. LEVEL OF EVIDENCE: IV.

Relationships between the global symptom score and electrophysiological findings after surgical release for carpal tunnel syndrome: Indications and outcomes.

PURPOSE: Regarding surgical indications for carpal tunnel syndrome (CTS), the hypothesis that the recovery processes of subjective symptoms differ among pain, sensory, and motor symptoms and correlate with recovery in objective nerve conduction studies was examined in the present study. METHODS: The global symptom score (GSS) is a method used to assess clinical outcomes and covers subjective symptoms, including pain (pain and nocturnal awakening), sensory (numbness and paresthesia), and motor (weakness/clumsiness) symptoms. The relationships between long-term changes in GSS and recovery in nerve conduction studies were investigated. RESULTS: Forty patients (40 hands) were included (mean age 65 years; 80% female; 68% with moderate CTS: sensory nerve conduction velocity < 45 m/s and motor nerve distal latency > 4.5 ms). Pain and nocturnal awakening rapidly subsided within 1 month after surgery and did not recur in the long term (median 5.6 years). Paresthesia significantly decreased 3 months after surgery and in the long term thereafter. Weakness/clumsiness significantly decreased at 1 year. Sensory nerve distal latency, conduction velocity, and amplitude significantly improved 3 months and 1 year after surgery, and correlated with nocturnal awakening in the short term (3 months) in moderate CTS cases. The patient satisfaction rate was 91%. CONCLUSION: Rapid recovery was observed in pain and nocturnal awakening, of which nocturnal awakening correlated with the recovery of sensory nerve conduction velocity. Patients with pain symptoms due to moderate CTS may benefit from surgical release.

Optimization of therapeutic strategies for selective lateral lymph node dissection after neoadjuvant chemoradiotherapy in patients with rectal cancer with clinical suspected lateral lymph node metastasis.

Background: Selective lateral lymph node (LLN) dissection with total mesorectal excision after neoadjuvant chemoradiotherapy (nCRT) is pointed out to reduce lateral compartment recurrence and to improve survival in patients with rectal cancer with LLN metastases. This study aimed to explore the safety, surgical indications, and survival outcomes of LLN dissection after nCRT. Methods: This multicenter retrospective study included patients with rectal cancer with clinical evidence of LLN metastases (n = 466) treated across three hospitals in China. Patients who underwent total mesorectal excision and LLN dissection were grouped into nCRT (n = 155) and non-nCRT (n = 291), respectively. Propensity score matching was used to minimize selection bias. Results: After matching, nCRT did not significantly increase the surgery duration, intraoperative blood loss or postoperative complications (P > 0.05). In a multivariate logistic regression analysis, poor/mucinous/signet adenocarcinoma (P = 0.042) and post-nCRT LLN short diameter ≥7 mm (P < 0.001) were independent risk factors for pathological LLN metastasis after nCRT. Overall survival (P < 0.001) and disease-free survival (P < 0.001) were significantly worse in patients with LLN metastasis, which was, however, not an independent risk factor for survival after eliminating confounders. Multivariate prognostic analysis of 40-patient subset with pathological LLN metastasis showed that distant metastasis, metastasis beyond the obturator or internal iliac region, and ≥2 LLN metastasis were independent predictors of poor overall survival. Conclusions: Selective LLN dissection after nCRT is safe and feasible with acceptable perioperative outcomes. Patients with a post-nCRT LLN short diameter ≥7 mm or poor/mucinous/signet adenocarcinoma should receive supplementary LLN dissection after nCRT. However, patients with distant metastasis, metastasis beyond the obturator or internal iliac region, and involvement of ≥2 LLN may not benefit from LLN dissection, and LLN dissection should be carefully considered in such patients.

Delphi-Based Survey for Surgical Indications in Biopsy Proven Active Adult Spinal Tuberculosis.

STUDY DESIGN: Delphi survey. OBJECTIVES: To obtain an expert consensus on various dilemmas in the surgical treatment of adult spinal tuberculosis (TB) patients. METHODS: Stage I included a literature review, stage II the identification of 40 Key Opinion leaders (KOLs) and a set of 46 questions, stage III included analysis of 3 rounds of the Delphi survey, and stage IV had final analysis and recommendations. For each question, the level of agreement needed to reach a consensus was set at greater than or equal to 70.0%. RESULTS: The first and second Delphi survey rounds received 62 and 58 responses, respectively, with 16 questions having more than 70% and two questions having 100% agreement in the first stage. The second stage saw a 70% agreement on six questions. Thus, a consensus was obtained on 22 questions. The recommendations that emerged were as follows: neurodeficit with corresponding radiology and neurological deficit appearing/deteriorating while on anti-tubercular chemotherapy(ATT) are absolute indications for surgery, duration of ATT before neurological deterioration need not be considered, epidural abscess does not need decompression unless concordant clinical neurological findings are present, pain not responding to medical management is not a surgical indication, active pulmonary TB, drug-resistant TB, and tubercular sacroiliitis are not considered as surgical indications, and hemoglobin and other health markers have little contribution to surgical indications. CONCLUSION: In order to resolve several conundrums in the surgical treatment of adult spinal TB, this Delphi survey is the first to achieve a national consensus from spine experts. The final recommendations cover the serological, radiographic, and clinical aspects of spinal TB.

[Münster standard: modified Paul® implantation in a condition following Preserflo® MicroShunt implantation. Video article]. / Münsteraner Standard: modifizierte PAUL®-Implantation bei Zustand nach PreserFlo® MicroShunt-Implantation. Videobeitrag.

OBJECTIVE OF SURGERY: The aim of this surgical technique is the modified placement of a Paul® implant (Fa. Advanced Ophthalmic Innovations, Singapur) in eyes after failure of Preserflo® MicroShunt (Fa. Santen, Osaka, Japan) implantation for the best possible adjustment of the intraocular pressure. INDICATIONS: The technique presented here is intended for patients suffering from more complex glaucomas, which were unsuccessfully previously treated with a Preserflo® Microshunt (Santen Inc.). SURGICAL TECHNIQUE: The special feature of the Münster standard is the choice of the surgical field and the waiver of a further tunnel placement. The patients receive a Paul® implant in the same quadrant as the previously inserted Preserflo® MicroShunt implant (superior temporal). The latter is explanted after preparation of the conjunctiva and priming of the Paul® implant with a Prolene 6.0 suture and fixation of the plate. In order to carry out the implantation of the Paul® tube through the existing 25-gauge tunnel, the latter is dilated laterally with an iris spatula under positioning of the anterior chamber. A surgical video, which is available online, shows the surgical technique in detail. ADVANTAGES OF THE MüNSTER STANDARD: The superior temporal surgical access promises easier handling. The fact that there is no need for a new tunnel effectively saves surgery time and is expected to reduce endothelial cell loss as only one tube remains in place in comparison to two anterior chamber tubes.

Analysis of the curative effect and prognostic factors in patients with scapular fracture with surgical indications after conservative treatment: a case series and clinical outcomes.

Background: The choice of treatment for scapular fractures is a topic worth discussing. The type of scapular fracture is often complex, and more and more scholars prefer surgical treatment to obtain better shoulder joint function. In addition, because of the rich blood supply and muscles of the scapula, some scholars believe that simple suspension can also achieve satisfactory clinical effects. The aim of this study was to investigate the curative effect and prognostic factors of patients with scapular fracture with indications for surgery after receiving conservative treatment. Methods: Patients with scapular fracture who did not receive surgical treatment from July 2016 to May 2021 were recruited from the orthopedic trauma database of Nanjing Gulou Hospital, and the data from patients with indications for surgery were screened out for a retrospective analysis. The data were obtained from the database of orthopaedic trauma patients in Nanjing Drum Tower Hospital. The relevant data were recorded during telephone and video follow-up visits. Linear regression was used to analyze the factors associated with disabilities of the arm, shoulder and hand (DASH) score after receiving conservative treatment. Results: A total of 21 patients were included in the final statistical analysis. All patients were followed up for 31.0±20.3 (range, 6-63) months, aged 52.9±12.7 (range, 27-71) years. All fractures had clinical healing with a 100% recovery satisfaction rate. Outcome measures of efficacy [both DASH scores and visual analogue scale (VAS) scores], were correlated with whether the fracture involved the superior border of the scapular, were not associated with the following variables: age (P=0.18), Injury Severity Score (ISS) score (P=0.10), the glenopolar angle (GPA) value (P=0.76), superior shoulder suspensory complex (SSSC) injury (P=0.82), and glenoid fracture (P=0.84). The range of motion of the affected shoulder was significantly reduced compared to the healthy shoulder (P<0.01), but the range of forward flexion and elevation was not significantly different from that of the healthy shoulder (P>0.05). Patients with fractures not involving the superior border of the scapula had a much lower range of motion in the affected shoulder than in the healthy shoulder during abduction (P<0.05). Conclusions: The range of surgical indications for scapular fractures with scapular fractures involving the lower margin of the scapular can be appropriately narrowed. Some patients with scapular fracture who have surgical indications can regain satisfactory shoulder function after receiving conservative treatment.

A Comparison of Complications and Survivorship after Reverse Total Shoulder Arthroplasty for Proximal Humerus Fracture compared with Cuff Tear Arthropathy.

Objectives: Traditionally used to treat rotator cuff tear arthropathy (CTA), reverse total shoulder arthroplasty (RTSA) is becoming increasingly utilized for the treatment of proximal humeral fractures (PHF). The purpose of this study was to use a matched cohort analysis to assess differences in 90-day complications as well as 2-year and 5-year implant survival between patients undergoing RTSA for CTA and patients undergoing RTSA for PHF. Methods: Patients with at least a 5-year follow-up who underwent primary RTSA for either PHF or CTA were identified in a national database (PearlDiver Technologies) using current procedural terminology (CPT) and international classification of diseases (ICD) 9 and 10 codes. Patients with a surgical indication of PHF were matched with patients with a surgical indication of CTA based on age, sex, Charlson Comorbidity Index, smoking status, and obesity (body mass index (BMI)>30). All-cause revision at the 2-year and 5-year postoperative time intervals were assessed. Reimbursements for the surgical care episode up to the 30-day, 90-day, and 1-year postoperative intervals were also assessed. Bivariate analysis was performed with a significance set at P<0.05. Results: In total, 802 PHF patients were matched with 802 CTA patients. Compared to CTA patients, PHF patients undergoing RTSA were significantly at increased risk of atrial fibrillation, anemia, and heart failure within 90 days of surgery. Notably, there was no significant difference in all-cause revision surgery at 2-year and 5-year postoperative intervals or hospital reimbursements at the 30-day, 90-day, and 1-year postoperative intervals. Conclusion: Preoperative indication appears to be an important driver of healthcare utilization for RTSA, as PHF patients undergoing RTSA have a higher risk of short-term postoperative complications compared to CTA patients. However, there is no difference in hospital reimbursement for the two indications of RTSA, suggesting that current payment modalities may not appropriately adjust for risk based on the surgical indication.

Pulmonary Artery Aneurysm: A Rarity and Surgical Enigma.

Given the low incidence of pulmonary artery aneurysms (PAAs), proven surgical indications do not yet exist. We present a patient with a 6.3 cm PAA who underwent an open sternotomy, pulmonary artery aneurysmectomy, and repair with an aortic homograft. We discuss surgical indications, including pain, growth in diameter, and diameter of 5.5 cm and larger. The current recommended surgical indication for the size of PAAs is based on recommendations for aortic aneurysms and observation in a small number of operable patients, highlighting the need for more discussion and reporting of this rare presentation.

Need for Tympanostomy Tubes in Children With Recurrent Acute Otitis Media Without Middle Ear Effusion.

OBJECTIVE: Children with recurrent acute otitis media (RAOM) presenting without middle ear effusion (MEE) do not meet indications for surgical intervention as outlined by Clinical Practice Guidelines (CPGs). The objective of this study was to determine which patients presenting with RAOM without MEE ultimately received tympanostomy tubes. STUDY DESIGN: Case series. SETTING: Single academic pediatric otolaryngology clinic. METHODS: Children (0-12 years) presenting with RAOM and no MEE were identified from October 2017 to December 2019. As per CPGs, no surgery was offered initially. Patients were given a semiurgent return appointment should they experience another suspected otitis media episode. If MEE was observed, tympanostomy tube insertion was offered. Patients were followed for 1-year following enrollment. RESULTS: One-hundred and twenty-four patients were included. The median age was 3.15 years old (interquartile range: 4.10). Seventy-five (60%) patients did not require additional follow-up and thus did not require tympanostomy tubes. Forty-nine (40%) patients were seen again; of these, 11 patients received tympanostomy tubes. Therefore, of patients presenting with no MEE, 91% did not require tympanostomy tubes. Patients who had surgery were younger on initial assessment than those who did not (mean difference 2.68 years, 95% confidence interval: 2.14-3.23). CONCLUSION: This study demonstrates the practical effect of adhering to CPGs for RAOM and suggests that many children may not require tympanostomy tube placement within the 1st year after the consultation if they did not initially present with MEE.

Increasing rates of ulnar collateral ligament repair outpace reconstruction in isolated injuries: review of a Texas surgical database.

Background: The gold standard of treatment for ulnar collateral ligament (UCL) injuries has been reconstruction. Despite early repair studies yielding less than satisfactory results, there has been recent renewed interest in UCL repair due to improved outcomes and new technologies. Data regarding clinical use of these procedures are lacking. The purpose of this study was to define the epidemiological trends of UCL repair and reconstruction surgery from 2010 to 2019, compare demographic characteristics of patients undergoing either procedure, and determine incidence of concomitant procedures in each surgical group as well as comparing respective patient-level charges. Methods: A retrospective database analysis of UCL surgeries was performed through the Texas Healthcare Information Collection database, a comprehensive and publicly available statewide billing dataset. Inclusion criteria were defined using Current Procedural Terminology billing codes for elbow UCL repair and reconstruction between 2010 through 2019, excluding patients who had concomitant elbow fractures or lateral collateral ligament tears indicative of high-energy trauma. Procedural volume changes, patient demographics, and commonly performed concomitant procedures including elbow arthroscopy, ulnar nerve surgery, and platelet-rich plasma injection were compared. Total patient-level charges were compared across groups. Results: A total of 1664 patients were included, consisting of 484 UCL repairs and 1180 reconstructions. Total UCL surgeries increased eleven-fold when corrected for population growth from 2010 (N = 25) to 2019 (N = 315). In 2010, repair constituted 23% of all UCL tear surgeries and increased to 40% by the end of 2019. The annual frequency of UCL repair increased at a 5.4% faster rate than UCL reconstruction from 2010 to 2019 (P < .001). There were no significant differences between any demographic data between UCL repair and reconstruction except for rural surgical settings which demonstrated 1.8 times greater odds of undergoing reconstruction (P = .05). There were no differences among commonly associated procedures including ulnar nerve surgery (P = .217), elbow arthroscopy (P = .092), and platelet-rich plasma injection (P = .837) with no differences in patient-level charges at any time point (P = .47). Conclusion: While reconstruction remains more common, the annual frequency of UCL repair is increasing at a faster rate. Since were no demographic differences aside from surgical setting, it can be inferred that patients who were previously receiving reconstruction are instead undergoing repair. This highlights the need for future studies to further identify surgical indications for the two interventions.

Surgical indications in pediatric arachnoid cysts.

INTRODUCTION: Arachnoid cysts are developmental lesions consisting of CSF collections within the subarachnoid space. There are many theories and hypotheses about their pathogenesis and histopathology and this may also explain the diversities seen in clinical behaviors of these cysts, their natural history and consequently their management where there is a great controversy about selecting patients for surgical intervention. The most common location in pediatrics is the Sylvian or middle cranial fossa and this made it gain more concern and greater debate about its management where its diagnosis is often accidently or associated with nonspecific symptoms. AIM: Our aim in this article was to review the main surgical indications for pediatric arachnoid cysts in the literature. CONCLUSION: We concluded that the decision for surgical intervention for pediatric arachnoid cysts is not a simple one and highly debatable and should be taken cautiously especially with sylvian arachnoid cysts that may reach a large size without symptoms. However, there is a consensus that the occurrence of symptoms definitely correlated to the presence of these cysts or their rupture with consequent subdural hematoma or hygroma are indications for surgical intervention. Large cysts in locations compressing CSF pathways causing hydrocephalus are also candidates for surgical fenestration. The surgical gain from prophylactic surgery is questionable particularly when asymptomatic.

The significance of forearm bone mineral density evaluation in determining surgical indications in primary hyperparathyroidism.

PURPOSE: Forearm osteoporosis is a well-known complication of primary hyperparathyroidism (PHPT). However, measuring forearm bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) at the distal radius is often neglected in clinical practice despite the fact that osteoporosis at any site is a criterion indicating surgery. We aimed to evaluate the importance and priority of forearm BMD and to determine its association with biochemical parameters. MATERIAL AND METHODS: Three hundred fourteen patients (272 females, 42 males) with PHPT who had BMD measurements at 3 sites were recruited for this retrospective study. The effect on surgical indications of osteoporosis only in the forearm was evaluated. Group 1 (n=151) with forearm osteoporosis and group 2 (n=163) without were compared in terms of biochemical and clinical parameters. RESULTS: In the overall study population, 165 of the 314 patients had osteoporosis in at least 1 site. Twenty seven percent (n=86/314) had osteoporosis only in the forearm, while the other 2 sites (lumbar spine and femoral neck) were normal or osteopenic. Surgery was indicated based on osteoporosis only in the forearm in 10% of patients (n=30/314). Corrected calcium and parathyroid hormone levels were significantly higher in group 1 than group 2 (p=0.001 and p<0.001, respectively) and were also negatively correlated with distal radius BMD, T-score and Z-score in the whole study group. CONCLUSION: Including the distal radius in BMD measurement increased the number of patients diagnosed with osteoporosis and for whom surgery was indicated. Calcium and PTH were also more frequently elevated in patients with forearm osteoporosis. These results show that distal radius BMD is relevant to the management of PHPT.

Controversy and consideration of gallbladder adenomyomatosis / 中华肝胆外科杂志

The detection rate of gallbladder adenomyomatosis has gradually increased, but the accuracy of preoperative diagnosis is low. Most doctors tend to expand the operation indications because they are worried about the carcinogenesis. But there are still great controversies on the key issues such as whether it is cancerous, operation indications and how to follow up for non-surgical patients. This article will review these key issues.

Diagnosis and treatment strategies of pancreatic cystic neoplasms in elderly patients / 中华消化外科杂志

Pancreatic cystic neoplasm (PCN) is characterized by cystic degeneration with a low incidence. With the development of imaging technology and the popularization of screening, the detection rate of this disease has been increasing in recent years, especially in the elderly population. Due to the multiple subtypes of PCN, difficult differential diagnosis, and the potential risk of malig-nant transformation, the formulation of reasonable diagnosis and treatment strategy is the key to treat PCN. Although many clinical guidelines have been released, the diagnosis and treatment strategies of PCN are still controversial. Elderly patients are generally weak, some with serious comorbidities, and have poor tolerance to surgery. In the process of diagnosis and treatment, clinicians need to pay special attention, carefully evaluate and weigh the advantages and disadvantages, so as to make the best plan for treatment. Based on the current guidelines and clinical experience, the authors summarize the diagnosis, surgical indications, and the whole-course management strategies of elderly patients with PCN, in order to provide suggestions for the diagnosis and treatment of this disease.

Outcomes and post-discharge follow-up of neonatal tracheotomy in NICU / 中国小儿急救医学

Objective:To study the outcomes and post-discharge follow-up of neonatal tracheotomy in neonatal intensive care unit(NICU).Methods:This study included patients who were admitted to NICU in Beijing Children′s Hospital from January, 2016 to August, 2021, and less than 28 days or 44 weeks(corrected age)on admission, and required tracheotomy.The patients were divided into tracheotomy group and the non-tracheotomy group (the parents signed to refuse the tracheotomy) according to whether perform tracheotomy.Demographic data, general hospitalization information, diagnosis, indications for tracheotomy, follow-up outcomes at 3/6/12 months of age after discharge of patients were collected and analyzed.Results:Totally 26 patients were included in this study, 14 cases in tracheotomy group and 12 cases in non-tracheotomy group.The average gestational age was(37.7±3.80)weeks and(38.99±1.83)weeks, and birth weight was(2 823.57±948.89)g and (3 320.83±378.76)g, respectively.There were no significant differences in sex, gestational age, birth weight, age on admission, weight on admission, age at diagnosis, ratio of endotracheal intubation for respiratory support on admission between two groups( P>0.05). The commonest indications of tracheotomy group were bilateral vocal cord paralysis(50.0%) and congenital anomaly/defect of throat/larynx(21.4%), and the commonest indications of non-tracheotomy group were bilateral vocal cord paralysis(50.0%) and vocal cord/subglottic mass(25.0%), and there was no significant difference between two groups( P>0.05). The rate of discharge-against-medical order of tracheotomy and non-tracheotomy group was 7.14% and 66.67%( P=0.003), respectively.The total follow-up rate of tracheotomy and non-tracheotomy group was 88.9% and 38.9%, while the follow-up rates at 3 months, 6 months, and 12 months were 100.0% vs. 50.0%, 83.3% vs. 41.7%, and 81.8% vs. 25.0%, respectively, whose differences were statistically significant(all P<0.05). In the 14 cases of tracheotomy group, 3 cases died, 4 cases successfully removed the tracheal cannula, 5 cases did not remove the tracheal cannula, and 2 cases were lost. Conclusion:Bilateral vocal cord paralysis is the commonest indication of neonatal tracheotomy.Parents′ compliance in the tracheotomy group is significantly higher than that in non-tracheotomy group.To give caring skill training for parents of neonates with tracheotomy before discharge is beneficial for improving the overall prognosis of children.

Evaluation value of subjective visual quality examination on surgical indications of the early cataracts based on objective scatter index values.

Aim: To evaluate the subjective visual functions of early cataracts patients and assess their surgical indications. Methods: Eyes were separated into a control group (Group A without cataract) and two early cataracts groups (Group B with 2.0 ≤ OSI < 3.0 and Group C with 3.0 ≤ OSI < 4.0). The objective scatter index (OSI), modulation transfer function cut-off frequency (MTF cut-off), and Strehl ratio (SR) values were applied to measure objective visual functions. The contrast sensitivity (CS) and scores of the questionnaires (QOL and VF-14) characterized subjective visual functions. Above visual functions were compared among three groups. Postoperative visual functions in Group B and C were analyzed to assess the outcome of surgery. Results: Ninety two subjects (126 eyes) were included in the study. All objective visual function in Group B were significantly better than Group C (all P < 0.01), but worse than Group A (all P < 0.01). Except for 1.5 c/d CS, subjective visual function in Group A were significantly better than Group B and C (all P < 0.05), but there was no significant differences between Group B and C. As for eyes that underwent surgery in Group B and C, all visual functions significantly improved after surgery (P < 0.05), except for 1.5 c/d CS in Group C. There were no significant differences among the three groups after surgery. Conclusion: The subjective visual function can be impaired in early cataracts patients with OSI < 3.0, whose objective visual functions were statistically better than patients with OSI ≥ 3.0. These patients can benefit equally from surgery as patients with OSI ≥ 3.0. Subjective visual functions can be used as surgical indications for these patients.

Surgical indications for mediastinal cysts-a narrative review.

Background and Objective: Whether and when surgical intervention is indicated for mediastinal cysts is a matter of some debate. While most mediastinal cysts are found incidentally, the anatomic location, clinical presentation, and symptoms, as well as the potential for malignancy, are important considerations that inform decisions related to whether to intervene surgically. The objective of this review is to summarize the current literature regarding the criteria for surgical excision of mediastinal cysts and provide a framework for the clinician and surgeon to arrive at a decision regarding the appropriateness of surgical intervention of mediastinal cysts. Methods: A review of the published literature in the last 45 years (1977-2022) was conducted through PubMed, MeSh and Google Scholar. We included retrospective reviews, meta-analyses, and case studies published in the English language. A single author identified eligible studies, and those identified were reviewed by the team until consensus was met. Pediatric literature was excluded from this review. Key Content and Findings: The current literature predominantly contains case studies, small retrospective studies, and meta-analyses describing mediastinal cysts. In the anterior mediastinum, multiloculated thymic cysts should be resected to rule out thymic malignancy. Intralesional fat, smooth borders, and a more midline location are features suggestive of a benign process, while asymmetric cystic wall thickening has been associated with malignancy. Both esophageal and bronchogenic cysts should be excised, taking into account the risk of complications (up to a 45% risk) of infection, rupture, or compression, as well as the rare risk of associated malignancy. Simple thymic and small pericardial cysts can be observed and followed with serial radiographic tools and should be resected if they increase in size, compress surrounding structures, or lead the patient to develop symptoms. Conclusions: Since mediastinal cysts are rare and often asymptomatic, there are no formal guidelines outlining when surgical intervention should be undertaken. Based on our review of the literature, surgical intervention should be pursued if the patient's symptoms correlate with radiographic findings of a mediastinal cyst, there is compression of the surrounding structures, and concern of malignancy is present.

Surgical Treatment of Substernal Goiter Part 1: Surgical Indications, Pre-Operative, and Peroperative Preparation.

Surgery is one of the most appropriate treatment options for many patients with substernal goiter (SG). However, SG surgery has some technical difficulties and a higher risk of complications compared to normal cervical thyroid surgery. Due to these technical difficulties and complication risks, which we also mentioned in our study, SG surgery should be performed by experienced and high-volume endocrine surgeons in centers with a large team and technical equipment. Pre-operative clinical and radiological evaluation and definitions in SG were evaluated in detail in our previous study. Detailed pre-operative evaluation, pre-operative risk assessment, surgical anatomy, anesthesia, appropriate surgical planning and estimation of surgical width are extremely important in SG surgery, where surgical technical difficulties and increased complication risks compared to cervical thyroid surgery come to the fore. In this study, we aimed to evaluate these preoperative and peroperative preparations in detail.

Pediatric neurosurgery AC-after COVID-19: What has really changed? A review of the literature.

The COVID-19 outbreak has dramatically changed the organization of Pediatric Neurosurgery all over the world. The departments involved developed similar plans to maintain emergency surgeries without reducing clinical activities. The Association of Pediatric Neurosurgeons wrote different memoranda to detail the surgical procedures not to be postponed with special attention given to high-risk pathology for COVID-19 contamination, like trans-naso-sphenoidal surgery. On this basis, we have conducted a complete literature review focusing on many topics: hospital organization, patients and parents screening, surgical indication criteria, outpatient clinic and teleconsultation, telematic conference and meeting, fellowship and training, and virtual multidisciplinary meeting.

Indications for nerve-sparing surgery for radical prostatectomy: Results from a single-center study.

Purpose: To explore the clinical indications of using the nerve-sparing technique in radical prostatectomy. Patients and methods: We retrospectively analyzed the clinical and pathological data of 101 patients who underwent radical prostatectomy (RP) at our institution. Twenty-five patients underwent open surgery, and 76 patients underwent laparoscopic surgery. The biochemical recurrence (BCR) rate was analyzed by the method of Kaplan-Meier. The distance between the ipsilateral neurovascular bundles (NVBs) and foci of prostate tumor (N-T distance) was measured in postoperative specimens. We defined the N-T distance >2 mm as the threshold to perform nerve-sparing (NS) in RP. Through logistic regression analysis, we determined the preoperative clinical indications for the nerve-sparing technique in RP. Results: The average BCR-free survival time was 53.2 months in these 101 patients with RP, with the 3- and 5-year BCR-free rates being 87.9% and 85.8%, respectively. The N-T distance was measured in 184 prostate sides from postoperative specimens of 101 patients. Univariate analysis showed that the percent of side-specific biopsy cores with cancer (≥1/3), maximum tumor length in biopsy core (≥5 mm), average percent involvement of each positive core (≥50%), PI-RADS score, and prostate MP-MRI imaging (extra-capsular extension) were associated with the N-T distance (p < 0.003). Furthermore, the percent of side-specific biopsy cores with cancer (≥1/3) (OR = 4.11, p = 0.0047) and prostate MP-MRI imaging (extra-capsular extension) (OR = 3.92, p = 0.0061) were found to be statistically significant independent predictors of the N-T distance in multivariate analysis. Conclusions: The clinical indications of nerve-sparing RP were <1/3 side-specific biopsy cores with cancer and no extra-capsular extension by prostate MP-MRI examination.
