Intelligent Verification Tool for Surgical Information of Ophthalmic Patients-A Study Based on Artificial Intelligence Technology.

With the development of day surgery, the characteristics of "short, frequent and fast" ophthalmic surgery are becoming more prominent. However, nurses are not efficient in verifying patients' surgical information, and problems such as patient privacy leakage are becoming more prominent. To improve the situation, we developed a new augmented reality (AR)-based tool for visual recognition and artificial intelligent (AI) interpretation of the pattern and location of patient surgical skin markings for the verification of the correct surgical site and procedure. The tool can also display a variety of other verbally requested patient information. The purpose of this proposal is to evaluate its feasibility of use by surgical nurses in a real clinical setting. We developed a tool with image recognition technologies to interpretation patient surgical skin markings and match the information obtained with the patients surgical records, thus, verify the patient's surgical information. Verification includes the proper surgical site and type of procedure to be performed. Nurses can interact with the device through its speech recognition capabilities and the device provides them with a variety of other requested patient information via a heads-up display. Three hundred patients in an outpatient ophthalmology clinic were divided into an AR intelligent verification experimental group and a manual verification control group. The accuracy of information verification, work time consumption, and economic cost data were compared between the 2 groups to evaluate the effectiveness of the AR Surgical Information Intelligent Verification Tool in clinical patient surgical information verification. There was no statistically difference in the correct rates of patient surgical information review between the experimental group (95.33%) and the control group (98.67%) (χ2 = 2.934, P = 0.087). The median time for information verification was 10.00 (10.00, 11.00) seconds in the experimental group and 21.00 (20.00, 24.00) seconds in the control group, a statistically difference (Z = 0.000, P < 0.001). The experimental group saved 11 seconds per patient per review compared with the control group. Considering 10,531 surgeries in 2023, printing 1 page of surgical information per 9 patients and requiring 4 copies, 4680 pages of printing paper could be saved. The AR Surgical Information Intelligent Verification Tool has advantages in assisting medical staff in patient surgical information verification, improving nursing efficiency, preventing surgical mark errors or nonstandardization, protecting patient privacy, and saving costs. It has certain research and application value in the scenario of patient surgical information verification in ophthalmic day ward.

Treatment of an Overcorrected Ear After Previously Performed Otoplasty.

No single otoplasty technique can be applied to all prominent ear deformities. The factors determining the type of operative method are based on the surgeon's preference for and confidence in the technique as well as long-term results. However, all cutting or scoring techniques include a risk of development of undesired edges, defects, or deformities on the ear being operated on. One of the patients' complaints and dissatisfactions after otoplasty is an overcorrected ear in its upper half. This condition leads to the loss of helix and prominent and conspicuous crus superior and antihelix. The article presents a simple and successful surgical procedure for correction of the condition.

Examining timing of periorbital interventions in patients with upper division facial paralysis.

Facial paralysis is a life-altering condition that may arise from various etiologies, ranging from trauma to malignancy. Permanent facial paralysis may occur secondary to facial nerve sacrifice or irreversible damage to the nerve. In these particularly devastating cases, protection and maintaining function of the eye is paramount. There are many effective lagophthalmos corrective surgical procedures available for these patients. While placement of eyelid weights and lid tightening surgeries are the cornerstone of eyelid rehabilitation, limited information exists on whether the timing of eyelid interventions in the setting of permanent facial paralysis impact outcomes, including need for revision surgery. A single-center retrospective chart review was performed for patients with irreversible facial paralysis treated with an upper eyelid weight between 2013 to 2022. Electronic health records were acquired to obtain facial paralysis etiology, associated clinical characteristics, the type of intervention, and the timing of intervention. Patients were classified as immediate if the eyelid weight operation occurred within 29 days of the initial facial paralysis and delayed if the surgery occurred 30 days or more after initial presentation. Outcomes were assessed in terms of revision procedures and surgical complications. There were 70 patients in total, with 35 patients in the immediate category and 35 patients in the delayed category. The most common etiology related to parotid gland pathology, and 58.6% of patients had facial paralysis from cancer-related surgeries. There were no significant differences in revision rates (p < 0.208) or in the types of procedures (p = 0.077) between the two groups. The complication rates also did not differ significantly between groups; however, there were only complications in the delayed intervention group. These findings suggest there is no difference in postoperative complications between groups, including the need for revision surgeries when comparing groups with immediate or delayed intervention. Thus, treatment plans should be customized based on patient and provider preferences.

Cholecystocolonic Fistula (CCF) Case Report

Introduction: Gallbladder disease is one of the most common conditions affecting the digestive tract. Autopsy reports have shown a prevalence of gallstones ranging from 11-36%, with cholecystitis being one of the most prevalent complications. Although cholecystoenteric fistulas are rare, with an incidence of 0.15-0.5% among patients undergoing cholecystectomy, they can present significant diagnostic and therapeutic challenges. The transverse colon is the second most common site for these fistulas after the duodenum. A high degree of suspicion is required to diagnose it preoperatively. Here, we present a noteworthy case of a 65-year-old male patient with a fistula between the gallbladder and transverse colon, complicated by severe adhesions and a large stone, underscoring the complexities associated with this condition. Case Presentation: The patient had a history of hypertension and gallbladder stones when he was admitted during the COVID-19 pandemic with acute cholecystitis. Two years later, he had an elective laparoscopic cholecystectomy and, during surgery, the surgical team noticed significant adhesions around the gallbladder. Further inspection during dissection of the gallbladder bed revealed a fistula between the transverse colon and the gallbladder, and a single large stone was identified. The patient’s surgical procedure was successful, and his postoperative recovery was uncomplicated. Conclusion: A fistula between the gallbladder and transverse colon is a rare complication of gallbladder disease, and the transverse colon is the second most common cholecystoenteric fistula after the duodenum. The presence of a fistula is usually a late sequence of chronic gallstone disease that requires appropriate diagnosis and correct treatment. In this case, the surgery was complicated by extensive adhesions around the gallbladder with an adjacent colon and a large stone with a fistula noted between the transverse colon and the gallbladder. However, through careful planning, correct surgical procedures, and skilled surgical expertise, the patient’s condition after surgery lacked complications. This case focuses on the importance of addressing all possible complications of gallbladder disease and adjusting surgical procedures accordingly.

Perioperative Benefits of a 3D Printed Spine Biomodel in the Setting of Congenital Scoliosis Surgery

The spine community is continuously adding to its armamentarium of intraoperative techniques for visualization and instrumentation of the spine. Recently, three-dimensional printed spine models were introduced for use in preoperative planning, surgical simulation, and intraoperative guidance. We present a 14-year old African male with congenital kyphoscoliosis, small stature, an obvious gibbus deformity and coronal imbalance, who underwent a three-staged posterior surgical correction procedure, during which a 3D-printed spine biomodel was utilized for better appreciation of his complex spinal deformity patho-anatomy. During the first stage of the procedure, he developed diminished lower extremity motor strength bilaterally and bowel/bladder control, but, following his third stage procedure and with focused rehabilitation efforts, he has regained full control of his bowel and bladder function, and is able to ambulate and perform activities of daily living independently, albeit still requiring intermittent walking support with a single forearm crutch due to residual left leg weakness. The 3D spine biomodel functioned successfully as a valuable tool and surrogate anatomic blueprint for the surgeons, enabling adequate appreciation of the complex bony anatomy which could not be easily resolved on the conventionally available imaging modalities, intraoperative navigation or robotic platform. Theoretically, up to $2900 USD in savings, translated from the mean estimated time saved per procedure with the use 3D-printed spine models has been proposed in some studies. Therefore, 3D-printed spine models have utility in complex spinal deformity correction surgery.

FUNCTIONAL CROWN LENGTHENING AS A PRE-RESTORATIVE PROCEDURE IN THE AESTHETIC ZONE

Introduction: Crown lengthening is a surgical procedure to increase the height of the clinical crown for aesthetic and restorative purposes, or combination. The indications include treatment of subgingival caries and altered passive eruption. Functional crown lengthening for restorative purposes in the esthetic zone should consider the concept of biologic width and the ideal proportion of the dentogingival complex. Case: A 39-year-old male patient was referred from the Department of Conservative Dentistry, RSGM UGM Prof. Soedomo to expose the maxillary anterior teeth crowns for full crown and veneer restorations. Clinical examination showed 11, 12, and 12 post root canal treatment with 3-4 mm remaining crowns. Teeth 13, 21, 22, and 23 appear short, excessive gingival display of 3 mm, with a diagnosis of altered passive eruption type 1B. Treatment: Functional crown lengthening was performed by gingivectomy followed by flap elevation, ostectomy, and osteoplasty. A fenestration was found at the apical of 22 and treated with regenerative procedure. Full crowns and veneers insertion was done 3 months after surgery. Crown lengthening as a pre-restorative procedure is a multidisciplinary treatment that considers the need for restoration by re-establishing the biologic width, to prevent inflammation and bone loss. In addition, adequate post- surgical tissue healing time prior to restoration is necessary to avoid gingival margin rebound and to assure long-term success of the restoration. Conclusionn : Functional crown lengthening as a pre-restorative procedure in the esthetic zone can gives satisfactory and stable results, with careful examination and correct surgical procedure.

Remote magnetic-guided catheter ablation versus manual ablation in patients with repaired congenital heart disease and atrial tachyarrhythmias: propensity-matched observational study of long-term results

Aim. To compare the long-term outcomes of the catheter ablation (CA) using remote magnetic-guided navigation (RMN) and manual radiofrequency CA (MAN) in patients with congenital heart defect (CHD) and incisional atrial tach-yarrhythmias (AT).Methods. In this retrospective study cohort, 67 patients were included with CHD and AT. CHD were classified based on complexity (simple, moderate, and complex) according to ACC/AHA guidelines 2008. Fifty-seven (85%) patients underwent at least one surgical procedure for CHD correction before CA. The patients were divided into the two groups regarding CA approach: the MAN group (n=42) and the RMN group (n=25). The primary endpoitnts was long-term freedom from any AT, including atrial fibrillation. Key secondary endpoints included perioperative and late complications. To compare freedom from any AT between the groups, 1:3 propensity score matching was applied, and 63 patients were matched. The matching was exact on CHD complexity. The weighted matched observations were assessed with univariate Cox regression with any AT as the outcome.Results. The median follow-up period was 20 months. In the matched MAN and RMN groups, 92.3% and 83.3% patients, respectively, had incisional АТ (p=0.27), the other patients having additionally AF. The mean fluoroscopy time was statistically significant lower in the RMN group compared with MAN (р=0.009) with longer procedural duration in the RMN group (p&lt;0.001). There was no statistically significant difference in perioperative and late complications. The freedom from any AT 36 months after CA was 78.9% in the matched RMN group and 47.2% in the matched MAN group. The comparison of freedom from any AT between the groups yielded p=0.040, hazard ration 0.32 [95% confidence interval 0.11; 0.95].Conclusion. RMN CA was superior over manual CA with respect to long-term freedom from AT in patients with CHD with similar safety profile.

Role of Temporomandibular Total Joint Replacement in Correction of Facial Deformities.

Individuals suffering from facial deformities experience esthetic, functional and social setback in their lives every day. These patients benefit greatly with single-stage temporomandibular joint replacement along with orthognathic surgical procedures to correct functional as well as esthetic components. Five individuals with facial deformities due to hemifacial macrosomia, fibrous dysplasia, idiopathic condylar resorption, ankylosis, etc., were treated with total joint replacement along with orthognathic surgical procedures for functional and esthetic correction. The customized temporomandibular joint was digitally custom designed, and the orthognathic procedures were virtually planned on NemoFAB software before performing the surgical procedure. Intraoperatively, the overall time was reduced considerably with minimal unpredictable complications. One-week postoperative computed tomographs were obtained and superimposed on preoperative virtual surgical planning which showed minimal discrepancy. Follow-up period of 18-30months was maintained for all the patients with stable results, minimal relapse and satisfactory functional abilities. Total joint replacement along with orthognathic procedure provides single-stage functional and esthetic corrections for the patients, considerably improving their quality of life. Precise preoperative surgical planning proves to be an indispensable step for achieving desired results with minimal margin of error and avoid any unseen complications during the surgical procedure.

Surgical Treatment of Adolescent Idiopathic Scoliosis with the ApiFix Minimal Invasive Dynamic Correction System-A Preliminary Report of a 24-Month Follow-Up.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional growth disorder. Corrective surgical procedures are the recommended treatment option for a thoracic angle exceeding 50° and a lumbar major curve of 40°. Over the past few years, dynamic growth modulation implants have been developed as alternatives to permanent fusion. The ApiFix system was designed as a 2D "posterior dynamic device" for curve correction. After implantation in a minimally invasive procedure, it uses polyaxial joints and a self-adjusting rod to preserve the degree of motion and to accommodate the patient's growth. It provides an effective method of controlling deformity and fills the gap between the conservative treatment of major curves that are >35° and the fusion procedure. The objective of the two-center cohort study was the analysis of the correction results of patients, who underwent surgical intervention with the ApiFix system. The inclusion criteria were AIS, Lenke type 1 or type 5, a major curve on bending films of ≤30°, and an angle of the major curve of between 35° and 60°. Postoperative radiograph data were obtained longitudinally for up to 24 months of follow-up and compared to preoperative (preop) values. For comparisons of the different time points, non-parametric tests (Wilcoxon) or paired t-tests for normally distributed values were used to analyze repeated measures. Overall, 36 patients (25 female and 11 male) were treated with the ApiFix system from April 2018 to October 2020. Lenke type 1 was identified in 21 (58%) cases and Lenke type 5 was identified in 15 (42%) cases. The average angle of the thoracic major curve for Lenke 1 was 43°. The preoperative lumbar major curve (Lenke 5) was determined to be 43°. Over a follow-up of 24 months, a correction of the major curve to an average of 20° was observed for Lenke 1 and that to an average of 15° was observed for Lenke 5. Lenke type 1 and type 5 showed significant changes in the major curve over the individual test intervals in the paired comparisons compared to the starting angle (Lenke 1: preop-24 months, 0.002; Lenke 5: preop-24 months, 0.043). Overall, 11 events were recorded in the follow-up period, that required revision surgery. We distinguished between repeated interventions required after reaching the maximum distraction length of the implant due to the continued growth of the patient (n = 4) and complications, such as infections or problems associated with the anchorage of the implant (n = 7). The results from the present cohort revealed a statistically significant improvement in the postoperatively measured angles of the major and minor curves in the follow-up after 24 months. Consequently, the results were comparable to those of the already established vertebral body tethering method. Alignment in AIS via dynamic correction systems in combination with a possible growth modulation has been a treatment alternative to surgical fusing procedures for more than a decade. However, the long-term corrective effect has to be validated in further studies.

Comparison of Motor Evoked Potentials Neuromonitoring Following Pre- and Postoperative Transcranial Magnetic Stimulation and Intraoperative Electrical Stimulation in Patients Undergoing Surgical Correction of Idiopathic Scoliosis.

The relationships between the results of pre- and intraoperative motor evoked potential recordings during neuromonitoring and whether idiopathic scoliosis (IS) surgical correction improves the spinal efferent transmission have not been specified in detail. This study aims to compare the results of surface-recorded electromyography (EMG), electroneurography (ENG, M, and F-waves), and especially motor evoked potential (MEP) recordings from tibialis anterior muscle (TA) bilaterally in 353 girls with right idiopathic scoliosis (types 1-3 according to Lenke classification). It has not yet been documented whether the results of MEP recordings induced by transcranial single magnetic stimulus (TMS, pre- and postoperatively) and trains of electrical stimuli (TES; intraoperatively in T0-before surgery, T1-after pedicle screws implantation, and T2-after scoliosis curvature distraction and derotation following two-rod implantation) can be compared for diagnostic verification of the improvement of spinal cord neural transmission. We attempted to determine whether the constant level of optimal anesthesia during certain surgical steps of scoliosis treatment affects the parameters of MEPs recorded during neuromonitoring procedures. No neurological deficits have been observed postoperatively. The values of amplitudes but not latencies in MEP recordings evoked with TMS in IS patients compared before and after surgery indicated a slight improvement in efferent neural transmission. The results of all neurophysiological studies in IS patients were significantly asymmetrical and recorded worse on the concave side, suggesting greater neurological motor deficits at p = 0.04. The surgeries brought significant improvement (p = 0.04) in the parameters of amplitudes of sEMG recordings; however, the consequences of abnormalities in the activity of TA motor units were still reflected. ENG study results showed the symptoms of the axonal-type injury in peroneal motor fibers improving only on the concave side at p = 0.04, in parallel with F-wave parameters, which suggests that derotation and distraction might result in restoring the proper relations of the lumbar ventral roots in the spinal central canal, resembling their decompression. There were no significant differences detected in the amplitudes or latencies of MEPs induced with TMS or TES when comparing the parameters recorded preoperatively and intraoperatively in T0. The amplitudes of TES-evoked MEPs increased gradually at p = 0.04 in the subsequent periods (T1 and T2) of observation. A reduction in MEP latency at p = 0.05 was observed only at the end of the IS surgery. Studies on the possible connections between the level of anesthesia fluctuations and the required TMS stimulus strength, as well as the MEP amplitude changes measured in T0-T2, revealed a lack of relationships. These might not be the factors influencing the efferent transmission in spinal pathways beside the surgical procedures. Pre- (TMS-evoked) and intraoperative (TES-evoked) recordings are reliable for evaluating the patient's neurological status before and during surgical scoliosis correction procedures. An increase in MEP amplitude parameters recorded on both sides after scoliosis surgery proves the immediate improvement of the total efferent spinal cord transmission. Considering comparative pre- and postoperative sEMG and ENG recordings, it can be concluded that surgeries might directly result in additional lumbar ventral root decompression. We can conclude that MEP parameter changes are determined by the surgery procedures during neuromonitoring, not the anesthesia conditions if they are kept stable, which influences a decrease in the number of false-positive neuromonitoring warnings.

Application of intraoperative optical coherence tomography in deep lamellar keratoplasty

Objective: To evaluate the clinical application value of intraoperative optical coherence tomography (iOCT) in deep anterior lamellar keratoplasty (DALK) using the big-bubble technique to bare Descemet's membrane. Methods: Retrospective case series. Clinical data of 92 patients (92 eyes) with monocular stromal corneal diseases who underwent big-bubble DALK in the Eye Hospital of Shandong First Medical University from January 2020 to August 2021 were collected. There were 53 males and 39 females. The average age was (53.2±16.0) years old. All patients underwent iOCT scanning to determine the location and depth of the injection needle after initial removal of the corneal lesion, to observe the integrity of the recipient bed, Descemet's membrane, after complete lesion removal, and to observe the adhesion between the corneal graft and the recipient bed and check folds on the recipient bed after suturing of the corneal graft. The intraoperative perforation of Descemet's membrane, postoperative thickness of the cornea and the recipient bed, visual acuity, and corneal astigmatism were recorded. Results: By iOCT, the thickness of the recipient bed was found to be about 1/2 of the corneal thickness and relatively uniform in all directions in 62 eyes (67.4%), so the sterile air was injected from the center of the recipient bed to separate it from the stromal layer. In 30 eyes (32.6%) with an uneven thickness of the recipient bed, the sterile air was injected from the paracentral area of the recipient bed. Under the guidance of iOCT scanning, 89 eyes (96.7%) did not experience any perforation of Descemet's membrane during surgery. The Descemet's membrane folds in the central 5-mm area of the recipient bed was observed and flattened in 20 eyes with the assistance of iOCT scanning. The postoperative corneal thickness was (578.95±108.26) μm, and the recipient bed thickness was (36.06±23.11) μm. The best corrected visual acuity of all patients at 6 months after surgery was 0.57±0.25 logMAR, which was significantly better than that before surgery (1.61±1.27 logMAR; P<0.001). The average corneal astigmatism at 6 months after surgery was (2.72±2.44) diopters. Conclusions: The application of iOCT scanning in DALK surgery assisted by the big-bubble method can provide safe guidance for surgeons to adopt correct surgical procedures, decrease the risk of Descemet's membrane perforation, reduce the recipient bed folds, and facilitate corneal interlayer adhesion, thereby improving the visual prognosis.

Morphological study of the anatomical variations of anterior belly of digastric muscle in Brazilian cadavers.

Cases of variations in anterior belly of the digastric muscle must be carefully identified to avoid misinterpretations and assist in the correct surgical or aesthetic procedure and help in the teaching of anatomy. The aim of this study was to describe the anatomical variations of anterior belly of digastric muscle in Brazilian cadavers. Thirty-one human heads were selected, from adult cadavers (18-80 years, 29 males and 2 females). The morphology of the anterior belly of the digastric muscle was observed, identifying the possible anatomical variations that were characterised and classified according to the amount of muscle bellies, fibre direction and place of origin and insertion. The morphometric measurements were performed using a digital calliper. To analyse the data obtained, photographic documentation, anatomical description and individual morphometric description of each muscle belly were performed. The incidence of anatomical variation was obtained in percentage (%). The anatomical variation of the anterior belly of the digastric muscle was present in 6 cadavers (19.31%; 1 female and 5 male). All anatomical variations presented an accessory belly to the anterior belly. However, these accessory bellies were configured differently in the location, direction of muscle fibres and in their dimensions (length and width). The gross anatomy of the anterior belly of the digastric muscle and their variations is important to assist in surgical procedures, pathological or diagnostic function. In addition, asymmetrical variations in the submental region must be carefully identified to avoid misinterpretations.

Common Anesthesia Challenges in a Case of Ankylosing Spondylitis Posted for the Correction of Spinal Deformity

Background: Ankylosing spondylitis (AS) is a type of inflammatory arthritis. Due to the rigid and brittle nature of spinal joints and multisystem involvement in the patients affected by ankylosing spondylitis, they are more prone to developing various complications. Different deformities require several surgical manipulations and perioperative anesthetic challenges, such as difficult intubation and positioning within the operating room. Case presentation: A 42-year-old man was diagnosed with ankylosing spondylitis, which has progressed over the last six years. He suffered from increasing pain and could not look forward, therefore; he has been scheduled for a corrective surgical procedure to address his spinal deformity to alleviate his pain and enhance the quality of his life by improving his functional abilities. Conclusion: Effective management of difficult airway cases with ankylosing spondylitis involving anatomical changes and reduced spinal mobility can be achieved by using awake fiberoptic-assisted nasal intubation. Intraoperative neuromonitoring and careful attention to proper positioning should be considered during the corrective spinal surgery to reduce complications.

Management of the Bone Deformity Caused by Congenital Cyst of the Periorbital Area: Analysis of the Surgical Technique and a Short-term Outcome

The congenital periorbital cysts like dermoids/epidermoids, in rare cases, can require not only its’ excision but also correction/camouflage of the caused bone deformity. This management can require virtual surgical planning, osteotomy, and placement of the custom-made patient implant. In this report, the ultrasonography (USG) was proved as a highly effective imaging for the presurgical verification of the mass’s structure and establishment of the clinical diagnosis. The multi-slice computed tomography (MSCT), even on a two-slice MSCT machine, provided high-quality three-dimensional reconstruction of the area of bone deformation caused by the cyst and allowed for accurate surgical planning. A 20-year-old male patient with a congenital periorbital epidermoid cyst that led to the deformation of the lateral orbital rim was treated using the soft tissue volume-increasing technique for the correction of bone deformation following cyst removal. Analysis of the terminological diversity related with dermoid/epidermoid cysts is presented. Early diagnostics and management of congenital periorbital cysts can decrease the visual, orbital, and esthetic complications, as well as the need to perform bone reconstructive surgeries or other corrective surgical procedures.

Less correction with minimally invasive surgery for adolescent idiopathic scoliosis compared to open surgical correction.

In this study, we investigated the relationship between the results of thoracic curve correction using minimally invasive surgeries in 35 patients and open surgical correction in 47 patients with adolescent idiopathic scoliosis. The correlations between the Cobb's angle of the primary and postoperative curves, angle of thoracic kyphosis and lumbar lordosis, correction percentage, derotation values, estimated blood loss, duration of surgery, and period of hospitalization after surgery were assessed by calculating the mean and standard deviation. Calculation and comparison were performed using Pearson correlation. The Cobb's angle correction ranged from 53.4° ± 11.8° to 6.7° ± 5.2° (p < 0.001) in the open surgical correction group and from 51.2° ± 11.4° to 11.7° ± 5.8° (p < 0.001) in the minimally invasive surgery group before and after surgery, respectively. The percentage of curvature correction was 88.2% ± 8.0% and 77.7% ± 10.7% (p < 0.001) in the open surgical correction and minimally invasive surgery groups, respectively. The estimated blood loss was higher in the open surgical correction group than in the minimally invasive surgery group (208.7 ± 113.4 vs 564.3 ± 242.7 mL). Axial rotation was changed from 29.1°± 7.5 to 17.1°± 6.8 (p < 0.001) in the open surgical correction group and from 28.9°± 7.8 to 19.4°± 6.4 (p < 0.001) in the minimally invasive surgery group. The duration of surgery was shorter in the open surgical correction group than in the minimally invasive surgery group (266.6 ± 64.3 vs 346.2 ± 70.5 min). A positive correlation between time of operation and Cobb's angle correction (in °) in open surgical correction (r = 0.37) and minimally invasive surgery (r = 0.43) was found. The open surgical correction procedures were more effective than minimally invasive surgery in correcting the spinal curve. The increase in the duration of open surgical correction increases the estimated blood loss, but it also more significantly improves the correction of Cobb's angle. III.

Morphometric analysis of fully ossified clavicle bones in North Indian Population: A Study

The clavicle bone is an essential anatomical structure that plays a crucial role in shoulder girdle function, as it serves as an attachment site for various muscles and ligaments. The clavicle bone is also important in forensic medicine, as it is frequently used for age and sex estimation. The aim of this study is to perform a morphometric analysis of fully ossified clavicle bones in the North Indian population and compare our findings with previous studies. The clavicle is considered to be an important bone when dealing with sex differences in skeletal material. The present study included 84 fully ossified clavicle bones (42 right-sided and 42 left-sided) of unknown sex and age. Parameters like maximum length, acromial breadth and height, and sternal breadth and height of clavicles were studied. All measurements were taken with the help of a vernier caliper and measured in mm. The maximum length, height, and width of the sternal end of the clavicle were found to be higher in the left-sided clavicle, while the height and width of the acromial end of the clavicles were found to be higher in the right-sided clavicles. These variations could be due to racial, genetic, or mechanical factors. These findings may be helpful to orthopedic surgeons involved in the surgical correction procedures of clavicle fractures.

Investigation of Accuracy and Influence Factors of Predicting Lenticule Thickness in Small Incision Lenticule Extraction by Machine Learning Models

Small-incision lenticule extraction (SMILE) is a safe and effective surgical procedure for refractive correction. However, the nomogram from the VisuMax femtosecond laser system often overestimates the achieved lenticule thickness (LT), leading to inaccurate estimation of residual central corneal thickness in some patients. In order to improve the accuracy of predicting achieved LT, we used machine learning models to make predictions of LT and analyze the influencing factors of LT estimation in this study. We collected nine variables of 302 eyes and their LT results as input variables. The input variables included age, sex, mean K reading of anterior corneal surface, lenticule diameter, preoperative CCT, axial length, the eccentricity of the anterior corneal surface (E), diopter of spherical, and diopter of the cylinder. Multiple linear regression and several machine learning algorithms were employed in developing the models for predicting LT. According to the evaluation results, the Random Forest (RF) model achieved the highest performance in predicting the LT with an R2 of 0.95 and found the importance of CCT and E in predicting LT. To validate the effectiveness of the RF model, we selected additional 50 eyes for testing. Results showed that the nomogram overestimated LT by 19.59% on average, while the RF model underestimated LT by -0.15%. In conclusion, this study can provide efficient technical support for the accurate estimation of LT in SMILE.

Parental Health Mindset Is Related to Preoperative Perceptions of Chest Wall Anomalies

IntroductionMindsets of health have been linked to different outcomes for patients with both surgical and medical conditions. A “growth” mindset, in which health is defined as malleable and subject to improvement, is associated with improved attitudes and outcomes when compared to a “fixed” mindset, in which health is defined as unchangeable. In pediatric surgery, parental growth mindsets of health have been correlated with better postoperative outcomes, including lower scores of anxiety and pain perceptions, for children. This was particularly notable in a study of postoperative outcomes for patients with pectus excavatum. In our current study, we extend our investigations to explore how health mindsets are associated with perceptions of chest wall anomalies before correction is undertaken. MethodsSeventy-six patients (71 males, mean age 14 y, and 43 excavatum) and 18 parents were surveyed during a routine chest wall clinic visit. Demographic and clinical information as well as the Health Mindset Scale and Pectus Excavatum Evaluation Questionnaire were administered and collected pretreatment. ResultsParental mindsets of health were significantly correlated with parent assessments of their children's chest pain, physical activity, and concerns about the life-time effect of the condition. A parental growth mindset was linked to lower scores of chest pain, higher ratings of activity, and lower overall level of concern. Furthermore, parental health mindsets also significantly correlated with children's own perceptions of their chest pain, physical activity, shortness of breath, and fatigue. Growth mindset also was linked to more positive ratings. ConclusionsParental growth mindset was associated with more positive assessments of children's symptoms and limitations due to pectus deformities than fixed mindsets. Health mindset has been linked to patient perceptions of, and outcomes for, diabetes, renal disease, allergies, scoliosis, and obesity. Further study into parental and patient mindset correlation may help elucidate factors for bracing compliance, and perhaps to better prepare children and parents for corrective surgical procedures.

Short-Term (30-Day) Morbidity of Biliopancreatic Diversion Compared to Roux-en-Y Gastric Bypass as Revisional Procedures for Failed Vertical Banded Gastroplasty.

Silastic ring vertical gastroplasty (SRVG) and vertical banded gastroplasty (VBG) are associated with a high failure rate due to weight regain and complications at long-term follow-up. Consequently, surgical correction for such procedures is warranted. Controversy exists as to which surgical procedure is the ideal choice for such correction. Our aim is to compare short-term outcome of Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) repair for failed VBG/SRVG bariatric procedures. The medical records of patients with failed SRVG who underwent corrective procedures at our institute between 2004 and 2018 were retrospectively reviewed. Patients characteristics, surgical approaches, and intraoperative and post-operative complications were examined and compared. Sixty patients in total underwent a surgical corrective procedure for failed SRVG. Thirty-one patients underwent RYGB, and 29 patients underwent BPD. Major complications were seen more in the RYGB group (35% = 11) compared to the BPD (6.9% = 2). Even though anastomotic leak rates were not statistically significant (p = 0.053), an apparent tendency for such a complication was noted in the RYGB group. RYGB procedure had an increased 30-day complication rate (p = 0.055) compared to RYGB. Laparoscopic approach had statistically fewer complications than open approach. No mortality was observed in either group. Our study showed that BPD is a safe option with less complication rates than RYGB in the short-term period for surgical correction of failed VBG/SRVG procedures.
