311. H ANASTOMOSIS FOR LOW INCIDENCE OF ANASTOMOTIC LEAKAGE, OBSTRUCTION AND GASTROESOPHAGEAL REFLUX

Abstract Background End to end intussusception anastomosis is associated with reduced anastomotic leakage for the two layers located at different levels and decreased reflux tends for the intussuscepted structures functioning as a morphological sphincter. Nevertheless, dysphagia often presents due to the anatomy that the inner layer of stomach is larger than its outer layer causing bulge to compress the esophagus below, especially at the sight which gastric wall bends inside. Methods Here we present procedures to perform H Anastomosis which derives from end to end intussusception anastomosis. The critical improvement was the intussuscepted tissue was transformed from the whole layers of esophagus and stomach to the muscular layers of them. The detailed process was shown in the supplementary video which is available at https://1drv.ms/v/s!AmCqlJJZqDPDgzVKV9w4VPd_i72G?e = ubNzUN. Results With removing the intussuscepted seromuscular layer of stomach and muscular layer of esophagus, H anastomosis eliminates the bulge and reduces the thickness of gastric wall covering the esophagus. Postoperative dysphagia is reduced while advantages of intussusception for leakage and reflux control are preserved. These conclusions have been testified by an unpublished prospective cohort study. Conclusion H anastomosis is a novel gastroesophageal anastomosis technique. The preliminary study showed good postoperative outcomes regarding leakage, obstruction and gastroesophageal reflux. Further validation is needed.

Autologous minced cartilage repair for chondral and osteochondral lesions of the knee joint demonstrates good postoperative outcomes and low reoperation rates at minimum five-year follow-up

PurposeMinced cartilage is a one-step, autologous procedure with promising short-term results. The aim of the present study was to evaluate mid-term results in a patient cohort with chondral and osteochondral lesions in the knee joint treated with minced cartilage.MethodsFrom 2015 through 2016, a total of 34 consecutive patients were treated with a single-step, autologous minced cartilage for knee chondral and osteochondral lesions. Numeric analogue scale (NAS) for pain and knee function were obtained prior to surgery and at 12, 24 and 60 months postoperatively. Secondary outcomes, including Lysholm score, Tegner activity score, and the International Knee Documentation Committee (IKDC) score, were recorded at final follow-up. MRI examinations of patients with unplanned radiological follow-up were analysed using the MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) score.ResultsA total of 28 patients (44.1% females, age at surgery: 29.5 ± 11.5 years) were available at a mean follow-up of 65.5 ± 4.1 months. Mean defect size was 3.5 ± 1.8 cm2. NAS for pain decreased from a median of 7 (range: 2–10) preoperatively to 2 (0–8) postoperatively. NAS knee function improved from a median of 7 (range: 2–10) to 3 (0–7) after five years, respectively. Satisfactory Lysholm (76.5 ± 12.5), IKDC (71.6 ± 14.8) and Tegner activity (4, range 3–9) scores were reported at final follow-up. Of all patients, 21(75%) and 19 (67.9%) reached or exceeded the PASS for the IKDC- and Lysholm score at final follow-up, respectively. The average overall MOCART 2.0 scores for all postoperatively performed MRIs (n = 23) was 62.3 ± 17.4. Four (14.2%) postoperative complications were directly linked to minced cartilage, one (3.5%) of which required revision surgery.ConclusionOne-step, autologous minced cartilage repair of chondral and osteochondral lesions of the knee without the necessity for subchondral bone treatment demonstrated good patient-reported outcomes, low complication rates, and graft longevity at mid-term follow-up. Minced cartilage represents a viable treatment option to more traditional cartilage repair techniques even in mid-term.Level of evidenceLevel III.

Long-term results following atrioventricular septal defect repair

BackgroundAtrioventricular septal defects (AVSD) represent 4–7% of congenital cardiac malformations. Definitive early repair is favored over prior pulmonary artery banding and delayed definitive repair in many centers. The aim of this study was to analyze long-term outcomes following AVSD repair over a 21-year period.MethodsA total of 202 consecutive patients underwent surgical AVSD correction between June 1999 and December 2020. Surgery was performed using the double-patch technique. The study data were prospectively collected and retrospectively analyzed. Primary outcomes were In-hospital mortality and overall long-term freedom from reoperation.ResultsMedian age at operation was 120 days (IQR 94–150), median weight was 5.0 kg (4.2–5.3). None of the patients died within the first 30 postoperative days. In-hospital mortality was 0.5% (1/202 patients). Median follow-up was 57 months (11–121). Overall freedom from reoperation at 5, 10 and 15 years was 91.8%, 86.9% and 86.9%, respectively.ConclusionAVSD repair with the double-patch technique is a safe and effective procedure with good early postoperative outcomes and low long-term reoperation rates.

Clinical and anatomical analysis of the epileptogenic spread patterns in focal cortical dysplasia patients.

Focal cortical dysplasia (FCD) is one of the main causes of intractable epilepsy, which is amendable by surgery. During the surgical management of FCD, the understanding of its epileptogenic foci, interconnections, and spreading pathways is crucial for attaining a good postoperative seizure free outcome. We retrospectively evaluated 54 FCD patients operated in Federal Center of Neurosurgery, Tyumen, Russia. The electroencephalogram findings were correlated to the involved brain anatomical areas. Subsequently, we analyzed the main white matter tracts implicated during the epileptogenic spreading in some representative cases. We prepared 10 human hemispheres using Klinger's method and dissected them through the fiber dissection technique. The clinical results were displayed and the main white matter tracts implicated in the seizure spread were described in 10 patients. Respective FCD foci, interconnections, and ectopic epileptogenic areas in each patient were discussed. A strong understanding of the main implicated tracts in epileptogenic spread in FCD patient remains cardinal for neurosurgeons dealing with epilepsy. To achieve meaningful seizure freedom, despite the focal lesion resection, the interconnections and tracts should be understood and somehow disconnected to stop the spreading.

Removal of grade IV vestibular schwannomas by retrosigmoid approach: results of a cumulative series of two European centers

Introduction The aim of our study was to study the association between end-of-surgery facial nerve stimulation threshold and extent of tumor resection in case of grade IV vestibular schwannomas. Materials and methods Grade IV VSs represent a surgical challenge as a risk/benefit ratio must be considered in balancing a satisfactory extent of resection against a good postoperative functional outcome. We reviewed a cumulative series of 57 patients with large/giant VSs who were operated on by retrosigmoid approach in the period from 2008 to 2018 in two European centers, namely San Filippo Neri Hospital, Rome, Italy and Masaryk Hospital, Usti nad Labem, Czech Republic. Extent of resection, intraoperative direct electrical stimulation threshold of facial nerve and postoperative facial outcome were examined. Results Total or near-total resection was accomplished in 40 (75.5%) cases. Two groups were compared: total or near-total resection (T + NT) and subtotal resection (ST); the end-of-surgery facial nerve stimulation threshold significantly differed (T + NT: 0.24 mA, ST: 0.44 mA, p = 0.036). A critical cutoff was found at 0.2mA; values similar or inferior to this correctly predicted total or near-total resection in 86.7% of cases. Thirty (56.6%) patients had a normal postoperative facial outcome (HB1). Among the 40 patients in T + NT group, 32 (80%) retained an acceptable facial function (HB1-2). Conclusions Lower facial nerve stimulation thresholds positively predict a broader extent of resection and total or -near total resection should be accomplished in such cases. Judicious (subtotal) resection is preferred if threshold values increase while dissecting firmly adherent tumors.

A comparative study of hearing outcome in cholesteatoma surgery canal wall up versus canal wall downmastoidectomy in 100 patients

Cholesteatoma is a well-demarcated sac of keratinizing squamous epithelium in the temporal bone, which is commonly characterized as “skin in the wrong place. The major goal of surgery for cholesteatoma is to make the ear safe and dry with increasing concern of the hearing outcome of patients. Two main surgical techniques employed are Canal Wall down (CWD) and Canal Wall up Mastoidectomy (CWU). In the current study, an attempt would be made to evaluate which technique would be better for achieving disease clearance with favorable hearing outcome and dry ear.1. To evaluate the hearing results following CWU and CWD surgery in patient with cholesteatoma.2. To decide surgical approach according to extension of disease.Materials and Methods:This is a prospective study involving 100 patients with cholesteatoma who had undergone CWD and CWU surgery over the period of 3 years.The choice of mastoidectomy, CWD or CWU, was the decision of the surgeon, after completely evaluating the patient, preoperatively and intraoperatively. All cases were followed up & assessed by autoscopic examination & PTA for minimum of 3 months. In the CWD group, mean hearing gain, in 3 months was 12±1.73dB. In the CWU group, hearing gain in 3 month postoperative period was 18±2.06 dB. Also the hearing gain between the two groups was compared and it was found to be statistically significant for the 3 months (p=0.0002) postoperatively; signifying that there was a comparable difference for CWU over CWD mastoidectomy in the matter of Hearing Gain. SNHL was also seen post operatively in both group. Total 3 (6%) patient in CWU had SNHL post operatively in comparison to 7(14%) patients in CWD. From our study results, we think that CWU is superior to the CWD surgery in cases of cholesteatoma because of good post-operative hearing outcome as well as less complication and law morbidity. CWD surgery should be used in cases of extensive cholesteatoma, mental retardation, not sure about follow up and inadequate middle ear space cases.

Outcomes in octogenarians following elective colorectal cancer surgery.

Colorectal surgery in octogenarians is increasing in prevalence and good surgical outcomes have been demonstrated. However, functional status and independence remain the main patient consideration with limited data on the long-term functional outcomes. A retrospective analysis was conducted for all patients aged above 80 undergoing surgery for colorectal cancer (CRC) from January 2018 to December 2019. Functional status assessment was made as part of pre- and post-operative allied health clinic appointments. Eastern Cooperative Oncology Group (ECOG) performance scores were recorded. Loss of independence (LOI) was defined as the reduced capacity to perform pre-morbid activities of daily living (ADL) and requiring increased supports. Forty-one patients aged 80 years or older had elective CRC resections with a median follow-up of 15 months [interquartile range (IQR): 8-20]. The median American Society of Anesthesiology (ASA) score was 3 and 90.2% (37/41) of patients had an ECOG score of 0 or 1. There was no 30-day mortality and 2 (4.9%) deaths occurred within 1 year. The median Clavien-Dindo score was 1, and 2 patients (4.9%) required unplanned intensive care unit (ICU) admissions. Twelve re-hospitalizations occurred with falls being the most common reason. LOI occurred in only 2 patients (4.9%) and on multivariate regression analysis, age and pre-morbid requirement of gait aids were predictive of LOI (P=0.042 and P=0.003, respectively). Gait aids were also associated with higher Clavien-Dindo scores (P=0.057) and increased length of stay (LOS) (P=0.009). Patients with advanced age undergoing surgery for CRC surgery can still have good post-operative outcomes and adequate functional recovery with pre-operative optimization and appropriate post-operative supports.

Urinary Bladder Diverticulum: A Single-Center Experience in the Management of Refractory Lower Urinary Symptoms Using a Robotic Platform.

Introduction Urinary bladder diverticulum (UBD) is commonly seen in urological practice and, in most cases, does not need treatment specifically directed towards it. However, it can give rise to symptoms that are not distinct from this finding. This makes the evaluation and management of this complex patient group challenging. We present our experience with robotic bladder diverticulectomy (RBD) for acquired bladder diverticulum to assess the outcomes and safety of this procedure when patient symptoms have failed to respond to either medical or surgical treatment directed at other associated contributing factors. Methods We retrospectively collected data on all patients who underwent RBD for persistent lower urinary tract symptoms (LUTS) at Royal Surrey County Hospital, Guildford, between 2016 and 2021, including baseline characteristics, urodynamic findings, intraoperative and postoperative outcomes, and a six-month follow-up. Patients who were diagnosed with cancer in the diverticulum, associated pathology that may contribute to their symptoms, or who had concomitant procedures at the time of RBD were excluded from this study. Results We had six patients who underwent RBD; the median age and body mass index (BMI) were 63.8 years (range 48-73) and 27.1 kg/m2(range 24-32), respectively. The most common presenting symptoms were refractory LUTS and recurrent urinary tract infections (UTIs). The urodynamic evaluation revealed varying findings like bladder outlet obstruction (BOO), poor compliance, and equivocal readings in these patients. All patients reported incomplete bladder emptying and double voiding, with half practicing clean intermittent self-catheterization (CISC). Diverticulum size averaged 9.4 cm (range 8.5-12). The median operative time and blood loss were 166 mins (range 150-180) and 75 mls (range 50-100), respectively. The average length of stay was 1.6 days (range 1-3). Three patients developed UTIs within a month after surgery, requiring a course of oral antibiotics. Post-void residual (PVR) measured an average of 32.6 mls (range 0-161) postoperatively compared to a preoperative average of 249 mls (range 125-400), showing a two-tailed p-value of 0.016. The International Prostate Symptom Score (IPSS) score for these patients showed an average of 27.83 (range 24-31) preoperatively compared to the postoperative average of eight (range 7-12), showing a two-tailed p-value of 0.0001. Final histology showed no malignancy, and all patients reported symptom improvement, with none requiring CISC after surgery. Conclusion RBD is a safe and effective procedure in carefully selected patients with refractory LUTS and UTIs showing good postoperative and functional outcomes. The presence of a large diverticulum can have a complex effect on bladder dynamics. In the era of robotic surgery and enhanced recovery, discussion about diverticulectomy should be encouraged after proper evaluation and counseling for patients who have failed to improve with other measures of treatment for their symptoms.

Surgical Treatment of Epilepsy with Bilateral MRI Abnormalities

To investigate the surgical outcomes of patients with drug-resistant epilepsy and bilateral brain magnetic resonance imaging (MRI) abnormalities who had undergone various epilepsy surgeries. Patients with drug-resistant epilepsy and bilateral brain abnormalities on MRI who underwent epilepsy surgery at the Severance Children's Hospital between October 2003 and December 2021 were included. The age of seizure onset was 18years or younger. Engel's classification was used to assess seizure outcomes at 1, 2, and 5years after surgery. A total of 40 patients met the inclusion criteria. The median age at surgery was 10.9years (interquartile range [IQR] 6.9-15.1); the median interval to surgery was 7.1years (IQR 2.7-11.5). One year after surgery, a favorable outcome of Engel class I-II was observed in 53% (21/40) of patients. At the 2- and 5-year follow-ups, 56% (20/36) and 63% (17/27) of patients showed good postoperative outcomes, respectively. Approximately, half of the patients with bilateral brain MRI abnormalities achieved seizure freedom after epilepsy surgery. The existence of bilateral brain MRI abnormalities should not hinder resective epilepsy surgery.

The Controlling Nutritional Status (CONUT) Score for Prediction of Microvascular Flap Complications in Reconstructive Surgery.

Microvascular flap surgery is a widely acknowledged procedure for significant defect reconstruction. Multiple flap complication risk factors have been identified, yet there are limited data on laboratory biomarkers for the prediction of flap loss. The controlling nutritional status (CONUT) score has demonstrated good postoperative outcome assessment ability in diverse surgical populations. We aim to assess the predictive value of the CONUT score for complications in microvascular flap surgery. This prospective cohort study includes 72 adult patients undergoing elective microvascular flap surgery. Preoperative blood draws for analysis of full blood count, total plasma cholesterol, and albumin concentrations were collected on the day of surgery before crystalloid infusion. Postoperative data on flap complications and duration of hospitalization were obtained. The overall complication rate was 15.2%. True flap loss with vascular compromise occurred in 5.6%. No differences in flap complications were found between different areas of reconstruction, anatomical flap types, or indications for surgery. Obesity was more common in patients with flap complications (p = 0.01). The CONUT score had an AUC of 0.813 (0.659-0.967, p = 0.012) for predicting complications other than true flap loss due to vascular compromise. A CONUT score > 2 was indicated as optimal during cut-off analysis (p = 0.022). Patients with flap complications had a longer duration of hospitalization (13.55, 10.99-16.11 vs. 25.38, 14.82-35.93; p = 0.004). Our findings indicate that the CONUT score has considerable predictive value in microvascular flap surgery.

Brief potentially ictal rhythmic discharges on intraoperative electrocorticography predict a good outcome of focal cortical dysplasia after surgical resection: a case report

BackgroundFocal cortical dysplasia (FCD) is a common cause of drug-resistant epilepsy. Electroencephalography (EEG) biomarkers that predict good postoperative outcomes are essential for identifying patients with focal epilepsies.Case presentationWe report the case of a 21-year-old female with seizure onset at the age of 9, characterized by left-hand dystonic posturing and impaired awareness, which evolved to bilateral tonic-clonic seizures, evaluated in a neurological referral center in Lima, Peru. During 6-h video-EEG, interictal EEG revealing focal brief potentially ictal rhythmic discharges (BIRDs) over the right frontal central region, lasting less than 10 s. The ictal features were characterized by low-voltage fast activity over the same area. Brain magnetic resonance imaging (MRI) demonstrated a focal lesion of focal cortical dysplasia type II in the right frontal lobe. The patient underwent a lesionectomy guided by electrocorticography, which showed continuous polyspikes. BIRDs showing a brief burst of spikes lasting longer than 0.5 s, were also identified on intraoperative electrocorticography (ECoG) and helped define the extent of resection. The patient obtained an Engel Outcome Class IA at 6 years of follow-up.ConclusionsThe atypical BIRDs on ECoG can be used as a prognostic biomarker for prolonged seizure-freedom outcome in patients with epilepsy. Additional reports are needed in developing countries with and without brain MRI lesions to advance outpatient presurgical evaluations despite limited resources.

Primary High-Grade Mucoepidermoid Carcinoma Lung Mimicking Endobronchial Papilloma: A Case Report and Review of Literature

Primary mucoepidermoid carcinomas (MECs) of the lung are rare and present a diagnostic challenge. MEC lung comes under the broad classification of primary salivary gland type tumours of the lung. It usually involves large airways and presents clinically and radiologically with non-specific features. We report the case of a 26-year-old female patient wherein an initial clinicoradiological consideration of tuberculosis and biopsy report of endobronchial papilloma led to misdiagnosis and treatment delay. Flexible bronchoscopic biopsy confirmed the diagnosis of MEC following which patient underwent curative pulmonary sleeve resection with good post-operative outcome. Final histopathology revealed high-grade MEC, stage as pT2N0, and thus, patient is receiving cisplatin-based adjuvant chemotherapy. More studies and reporting of such cases are needed to formulate guidelines and avoid delay in management.

Isolated giant aortic arch aneurysm repair in a 13-year-old girl: a case report

BackgroundAortic arch aneurysm is a very rare condition in children. Surgery is the life saving procedure but it performing might be challenging due to the complex anatomy.Case presentationWe describe a 13-year-old girl who was diagnosed to have an isolated giant aortic arch aneurysm. This girl was referred to our institution with persistent cough as a leading symptom, which started two months ago. Surgery was performed as combined approach: left-sided thoracotomy and midline sternotomy. The left subclavian artery was re-implanted via supraclavicular approach to the left common carotid artery end-to-side anastomosis. Aneurysm was excised after midline sternotomy and initiation of cardiopulmonary bypass under mild hypothermia. Histological evaluation of the wall of the aneurysm revealed no evidence of any specific changes.ConclusionsThe using of the combined method was characterised by a good postoperative surgical results. Pediatricians should be aware of persistent cough in children as a symptom of mediastinal mass of different origin and identity.

Endoscopic Plantar Fasciotomy as an Effective and Reliable Treatment for Plantar Fasciitis: An Overview of the Literature.

Plantar fasciitis is a common cause of heel pain. The aim of this study was to review the current literature and attempt to clarify whether endoscopic plantar fasciotomy (EPF) is an effective and reliable treatment for plantar fasciitis in comparison with other invasive or noninvasive treatments. We performed an electronic search of the medical literature in PubMed database using combinations of the following keywords: plantar fasciitis, endoscopic treatment, and plantar aponeurosis. Overall, we had shown that patients had better scores following EPF/endoscopic plantar fascia release. The clinical scores were improved postoperatively and most of the patients were satisfied. Furthermore, the clinical trials showed that time to return to work or to previous activities was shorter compared with other treatments. These studies suggest that EPF/endoscopic plantar fascia release is probably an effective treatment of chronic plantar fasciitis. EPF is an efficient, safe treatment with good early postoperative results in patients with recalcitrant plantar fasciitis. There is evidence that other methods are equivalently effective for EPF, and some authors support that they should be considered as a second-line treatment because of their minimal invasive character and very low risk of complications; thus, more research is required.

Long-term Outcome of Total Femur Replacement.

Total femur replacement is an option instead of amputation for extensive bone tumour or after revision surgery with a massive bone loss. Over a long period of time the patients may need revision surgery, and this might affect the functional outcome. We reviewed all consecutive total femur replacements done for primary and revision surgery of primary bone tumours in our centre to evaluate the long-term functional outcome and survival. All patients who had total femur resection and reconstruction with modular endoprosthesis replacement in our centre from June 1997 to May 2022 were reviewed. The respondents were surveyed through WhatsApp using google form which was translated into Bahasa Malaysia based on the Musculoskeletal Tumour Society Scoring System (MSTS). The data were presented as descriptive data on the final survival of the limb and prosthesis. Ten patients underwent total femur replacement. There were eight osteosarcoma, one giant cell tumour and one chondromyxoid fibroma. Three patients with osteosarcoma succumbed to pulmonary metastases; all had good early post-operative functional outcomes without local recurrence. Seven patients were available for long term evaluation of function with a mean follow-up of 17.6 years (ranged 10-25 years). Four patients with total femur replacement had good functional outcomes (60-80%) without revision with 10-25 years follow-up. Three patients experienced acetabulum erosion and chronic pain that required early hip replacements. Two of them were complicated with superior erosions and bone loss and subsequently were managed with massive reconstruction using cemented acetabulum cage reconstruction. The other has diabetes mellitus with chronic infection following revision of distal femur endoprosthesis to total femur replacement and subsequently underwent limited hemipelvectomy after 14 years. Total femur replacement offers a good long term functional outcome and prosthesis survival and is a favourable option for limb salvage surgery.

Techniques for Fixing Anterior Cruciate Ligament Tibial Avulsion Fractures in Multiligament Knee Injuries

Background: In patients with multiligament knee injuries, anterior cruciate ligament (ACL) tears are often reconstructed. Recent studies have shown good results when the ACL tibial avulsions are repaired. The advantages of ACL tibial avulsion repair are the preservation of the native anatomy, reduction in donor site morbidity, and lower risk of tunnel convergence. Indications & Technique Description: We show 2 techniques for repairing ACL tibial avulsion fractures. The first case describes the use of hybrid fixation (screw and suture), with staged repair and reconstruction in a patient with high-energy knee fracture-dislocation. The second case describes the use of suture ACL repair via tunnels in a patient with a low-energy knee dislocation and an ACL tibial avulsion fracture. When repairing ACL tibial avulsion fractures, screw fixation is recommended for larger tibial fragments. In smaller comminuted fragments, tying sutures passed through the ACL via tibial tunnels may be more appropriate. Results: Several studies have demonstrated good postoperative results in patients following the fixation of ACL tibial avulsion fractures. Both screw and suture fixation are effective methods of repairing ACL tibial avulsion fractures and have similar postoperative outcomes. It has been found that screw fixation is associated with a higher risk of subsequent surgery and implant removal than suture fixation. Conclusion: The repair of ACL tibial avulsion fractures in multiligament knee injuries is an alternative to ACL reconstruction that demonstrates excellent postoperative patient outcomes, good patient satisfaction, and good return to sports.

Comparison of visual outcomes in adult patients with different types of developmental cataracts after toric multifocal intraocular lenses implantation

Purpose To analyze and compare the visual performance and patient satisfaction following the implantation of toric multifocal intraocular lenses (TMIOLs) in adult patients with different types of developmental cataracts (DC) accompanied by corneal astigmatism (CA).Methods This is a prospective observational cohort study. Patients diagnosed with DC aged 18–30 years were divided into three groups according to the anatomic location of the lens opacity: cortical, nuclear, and posterior subcapsular (PSC) groups, and implanted with TMIOLs. Visual acuity (VA), postoperative refractive astigmatism (RA), intraocular lens (IOL) rotation, high-order aberrations (HOAs), modulation transfer function (MTF) curve, and Strehl ratio were compared. The functional vision and incidence of photic phenomena were surveyed using questionnaires.Results Fifty-five eyes of 37 patients were enrolled and completed a 1-year follow-up. The mean CA was 2.06 ± 0.79 D preoperatively, and the mean RA was 0.29 ± 0.30 D 3-month postoperatively. The IOL rotation was 2.48° ± 1.89°, with no deviation > 10°. At 12 months, mean uncorrected distance VA improved from 0.93 ± 0.41 preoperatively to 0.08 ± 0.08 logarithm of the minimum angle of resolution (logMAR), mean uncorrected near VA increased from 0.45 ± 0.30 preoperatively to 0.12 ± 0.11 logMAR, and mean uncorrected intermediate VA was 0.14 ± 0.08 logMAR. The cortical and nuclear groups displayed better improvements in uncorrected near and intermediate VA than that in the PSC group. Similar results were observed in the 3-month defocus curves, HOAs, MTF curve, halo incidence, and near vision satisfaction.ConclusionIn adult patients with DC accompanied by CA, TMIOLs implantation achieved good postoperative visual outcomes and significantly reduced glasses dependency. Patients with cortical or nuclear lens opacity showed better whole-course VA and quality of vision, while patients with PSC opacity showed unsatisfactory near vision and suffered more photic phenomena.

The Early Effects on Tricuspid Annulus and Right Chambers Dimensions in Successful Tricuspid Valve Bicuspidization.

It is unclear to what degree of tricuspid annulus (TA) reduction is necessary to achieve good postoperative results in surgical bicuspidization. The study aimed to evaluate TA and right heart chamber's dimensions before and after heart surgery; and to compare TA parameters assessed by different modalities. Forty patients underwent mitral valve surgery with or without concomitant tricuspid valve (TV) bicuspidization. Preoperative and postoperative measurements of TA dimensions were performed prospectively using two-dimensional (2D) and three-dimensional (3D) transthoracic echocardiography (TTE). Additionally, preoperative transesophageal echocardiography (TOE) was performed in the operating room prior to surgery. All patients had no or mild TR immediately after surgery. There was a significant reduction in 2D and 3D parameters of the TV and right chambers in the TV bicuspidization group. However, TV leaflets' tethering parameters did not change significantly. Preoperative 3D TTE measurements were smaller than those obtained through 3D TOE in the operation room, before surgery under general anesthesia. The 2D systolic apical 4Ch diameter and the parasternal short axis diameter mainly represent the 3D minor axis of the TA and are smaller than its 3D major axis. Although bicuspidization results in a one-third reduction of the TV area, tethering of the TV leaflets remains unchanged. Moreover, 3D TOE parameters of the TV under general anesthesia are larger than preoperative 3D TTE measurements. Conventional 2D measurements are insufficient for evaluating the maximum diameter of the TA.

Outcomes of Stage IIIa and Well-Selected Stage IIIb or Oligometastatic Stage IV Non-Small Cell Lung Cancers Managed by Multimodal Therapy Including Immunotherapy and Surgery

Abstract Background Resectable locally advanced non-small cell lung cancers (NSCLCs) are managed by multimodal approaches including systemic therapies followed by surgery. The recent inclusion of immunotherapy in neoadjuvant protocols has significantly improved tumor responses. In selected situations, bulky N2, N3 or oligometastatic NSCLCs with treated metastasis have shown excellent regression following chemo-immunotherapy and could be considered for surgery. Aims We here compare the oncological outcomes of stage IIIA (single N2) with stage IIIB (bulky N2, N3) or oligometastatic stage IV NSCLCs managed by chemo-immunotherapy followed by surgery. Methods We reviewed all patients treated in our institution between April 2017 and June 2022 for a locally advanced or oligometastatic NSCLC with chemo-immunotherapy followed by surgery in our prospectively collected database. We recorded, for each patient, the clinico-pathological characteristics, perioperative complications and oncological outcomes. Results Forty-eight patients (27 single station N2 stage IIIA (group 1) and 21 bulky N2, N3 or oligometastatic NSCLC (group 2)) were identified. Patient characteristics were comparable between groups. Surgery consisted in lobectomy (81%), bilobectomy (17%) or pneumonectomy (2%). Complete resection was achieved in 46 (95%) patients with R1 resection in two patients due to lymph node effraction. Complete tumor pathological response was achieved in 26% in group 1 and 33% in group 2. Postoperative morbidity was 48% in group 1 and 81% in group 2 (p=0.05). There was no mortality. Median follow-up was 16 months (IQR: 9-32). Progression-free survival was 6 months (IQR: 3-18) in group 1 and 5 months (IQR: 2-7) in group 2 (p=0.04). Overall recurrence rate was 40% (comparable between groups (p=0.08)) and consisted, in majority, of distant metastasis. Overall survival was comparable between groups (p=0.05). Conclusions The inclusion of immunotherapy in induction protocols has improved tumor response and allowed to consider advanced NSCLCs for surgical resection with good postoperative and oncological outcomes.

Clinical characteristics and surgical outcomes in children with mild malformation of cortical development and oligodendroglial hyperplasia in epilepsy.

Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is a new and rare histopathological entity of cortical developmental malformations. The clinical characteristics of MOGHE remain challenging. Children with histologically confirmed MOGHE were retrospectively studied. The clinical findings, electroclinical and imaging features, and postoperative outcomes were analyzed, and previously published studies were reviewed up to June 2022. Thirty-seven children were included in our cohort. Clinical characteristics included early onset in infancy (94.6% before 3 years), multiple seizure types, and moderate or severe delay. Epileptic spasm is the most common seizure type and initial manifestation. The lesions were mainly multilobar (59.5% multiple lobes and 8.1% hemispheres), and predominance in the frontal lobe was observed. The interictal EEG pattern was circumscribed or widespread. The prominent MRI characteristics were cortical thickening, cortical/subcortical hyperintense T2/FLAIR signal, and blurring at the GM and WM transition. Among the 21 children followed up for more than 1 year after surgery, 76.2% were seizure-free. Preoperative interictal circumscribed discharges and larger resections were significantly associated with a good postoperative outcome. The clinical features of 113 patients in the reviewed studies were similar to those we reported, but the lesions were mainly unilobar (73.5%) and Engel I was achieved in only 54.2% after surgery. Distinct clinical characteristics in MOGHE, especially age at onset, epileptic spasm, and age-related MRI characteristics, can help in early diagnosis. Preoperative interictal discharge and surgical strategy may be predictors of postoperative outcomes.
