Rates of Textbook Outcome Achieved in Patients Undergoing Liver and Pancreatic Surgery

Backgorund: Textbook outcome (TO) is a composite measure that reflects the most desirable surgical results as a single indicator. The aim of this study was to assess the achievement of TO at a hepatopancreatobiliary (HPB) surgery unit in a Spanish tertiary hospital. Methods: We performed a retrospective observational study of all consecutive patients who underwent HPB surgery over a 4-year period. Morbidity according to the Clavien-Dindo classification at 30 days, hospital stay, risk of morbidity and mortality according to the POSSUM, and mortality and readmissions at 90 days were recorded. TO was considered when a patient presented no major complications (≥IIIA), no mortality, no readmission, and no prolonged length of stay (≤75th). Results: 283 patients were included. Morbidity >IIIA was reported in 21.6%, and 5.7% died; the median postoperative stay was 4 days. TO was achieved in 56.2% of patients. Comparing patients who presented TO with those who did not, significant differences were recorded for the type of procedure and the expected risk of morbidity and mortality calculated according to the POSSUM scale. There were significant differences between patients with major resections (TO rates: major hepatectomy (46.3%) and major pancreatectomy (52.5%)) and those with minor resections (TO rates minor hepatectomy (67.7%) and minor pancreatectomy (40.4%)). Conclusions: TO is a useful management tool for assessing postoperative results.

Thoracic hypertrophied ligamentum flavum: A retrospective study of pre-operative factors and surgical outcome

Objectives: Thoracic hypertrophied ligamentum flavum (HLF) is a rare cause of thoracic myelopathy which requires surgical treatment. The study aims to analyze the pre-operative factors and surgical outcomes in patients with thoracic myelopathy secondary to HLF. Materials and Methods: This is a retrospective study of patients who underwent surgery for thoracic myelopathy due to HLF at a single center from December 2015 to November 2023. We included patient’s demographic data, clinical symptoms, radiological details, operative details, and outcome. We used Nurick’s grading system for outcome evaluation in pre-operative, post-operative, and follow-up. Relationship of various pre-operative parameters was evaluated with surgical outcomes on binary scale (favorable group [Nurick’s grade 1 and 2] and unfavorable outcome [Nurick’s grade 3–5]) using univariate and multivariate analysis. Results: A total of 57 patients were included in the study. On analyzing various prognostic factors with respect to favorable and unfavorable outcomes using univariate analysis, four factors came out to be statistically significant which were segments involved (multi vs. single segment involvement) (P < 0.05), walking difficulty (P < 0.05), intramedullary signal changes on T2-weighted magnetic resonance imaging (MRI) (P < 0.001), and pre-operative Nurick’s grade (P < 0.001). On multivariate analysis, only one factor, pre-operative Nurick’s grade came out statistically significant. Conclusion: Various factors are important in predicting the outcome of a patient with thoracic myelopathy secondary to HLF. The most important of which is pre-operative Nurick’s grade. Other factors that also affect the outcome are the presence of multisegmented disease and intramedullary T2 signal changes on MRI.

Evolution of Thoracic Disc Herniation Surgery: Future Perspectives from a Systematic Review and Meta-Analysis

Background: The neurosurgical treatment of thoracic disc herniation (TDH) has undergone dramatic changes over the years in terms of surgical approaches and intraoperative technological tools. There is still no unanimous consent on the criteria for approach selection, and the choice varies among Institutions. The aim of this study is to compare anterior and posterolateral approaches for TDH in terms of functional and surgical outcomes. Methods: A systematic literature review and meta-analysis according to PRISMA guidelines from EMBASE, PubMed, Cochrane Library, Web of Science, and Google Scholar online databases up to May 2024 incorporated studies that reported outcomes of thoracic disc herniation surgeries. Analyzed factors included major peri- and postoperative complications, intraoperative blood loss, hospital stay, neurological improvement, and complete hernia resection. Random-effect models were used to calculate pooled odds ratios and mean differences. Results: The posterolateral approach was associated with significantly lower rates of major medical (OR 0.14, 95% CI: 0.07 to 0.27) and surgical complications (OR 0.61, 95% CI: 0.38 to 0.99) compared to the anterior approach. Additionally, posterolateral approaches reduced intraoperative blood loss and shorter hospital stays. Posterolateral techniques were linked to higher odds of neurological improvement (OR 0.65, 95% CI: 0.43 to 0.99) and higher rates of complete hernia resection (OR 0.38, 95% CI: 0.21 to 0.71). Conclusions: Posterolateral approaches offer advantages in terms of safety, recovery, neurological improvement, and complete hernia resection. More extensive prospective studies are needed to confirm these findings and refine surgical strategies. Emerging technologies, such as the exoscope and 45° endoscopy, may further enhance surgical outcomes.

Exploring the Potential Use of Virtual Reality with a Supraorbital Keyhole Craniotomy for Anterior Skull Base Meningiomas: Two Case Reports

Introduction: A supraorbital keyhole craniotomy (SOKC) is a novel alternative to frontal craniotomies for accessing the anterior fossa for resecting tumors and clipping aneurysms; however, its implementation is limited in patients at a high risk of complications. We present two cases involving the use of augmented reality (AR) and virtual reality (VR) for patient selection and preoperative planning for a supraorbital tumor resection of anterior fossa meningiomas. Methods: This is a prospective, single-center case series at a research institute. We identified patients with an anterior or middle fossa meningioma regardless of age, gender, and tumor characteristics who could undergo an SOKC and MRI. The preoperative planning was performed with the BrainLab Magic Leap AR/VR platform. The meningiomas were resected through the SOKC under neuronavigation. Results: We identified two cases: a 37-year-old male with a meningioma in the sellar region and an 84-year-old male with a right anterior fossa meningioma, both confirmed by MRI. Both patients had a complete tumor resection by a minimally invasive SOKC after preoperative planning with the AR/VR platform. Postoperatively, hyponatremia complicated the first case, while the second case developed an intracranial hemorrhage. They both recovered after the appropriate interventions. Conclusions: The use of an SOKC for anterior skull base meningiomas should be individualized after considering the lesion characteristics, vascular control needs, and the surgeon’s expertise. VR/AR-assisted preoperative evaluation and planning will optimize the patient selection and surgical outcomes. We can utilize VR/AR technologies to identify patients that will benefit from an SOKC and expand the implementation of the approach beyond its current limitations.

The effect of prebiotic fibre on the gut microbiome and surgical outcomes in patients with prosthetic joint infection (PENGUIN) - study protocol for a randomised, double-blind, placebo-controlled trial (ACTRN12623001273673)

BackgroundProsthetic Joint Infection (PJI) is the most devastating complication of arthroplasty surgery and affects 1–5% of patients. Despite strict adherence to aseptic protocols and preventive measures, infection is the most common reason for revision arthroplasty, and the incidence is increasing. Treatment of PJI is challenging and often requires repeated major surgeries with sequentially poor results. The continued occurrence of PJI, and persistence after treatment, brings into question the current treatment paradigm. Preclinical evidence suggests a link between altered gut health and the risk of PJI in arthroplasty patients. Resistant starches helps to restore gut physiology by enhancing the beneficial microbiome and producing short-chain fatty acids, which have several health-conferring properties. The primary aim of this study is to investigate the effect of a commercially available prebiotic fibre formulation on the gut microbiome in PJI patients planned for a two-stage revision surgery.MethodsA double-blind placebo-controlled trial will assess the effect of 8-week supplementation of a commercially available prebiotic supplement in patients presenting with first-time PJI undergoing two-stage revision surgery. The supplementation phase will start after the first stage revision, and 80 patients will be randomised to receive either a test product (34 g of resistant starch) or a placebo (custard powder) daily for eight weeks. Stool and blood specimens will be collected at baseline, four weeks and eight weeks after the first-stage surgery and once at second-stage surgery. Gut microbiome profile, inflammatory cytokines and gut permeability biomarkers will be measured. Tissue specimens will be collected intra-operatively during first and second-stage surgeries. Baseline dietary patterns and gut symptoms will be recorded using validated questionnaires. Treatment outcomes will be reported for both cohorts using the Delphi criterion at one and two years after second-stage surgery.DiscussionThis will be the first study to investigate the relationship between gut health optimisation and preventing PJI recurrence in arthroplasty patients. If supplementation with resistant starch improves gut health and reduces systemic inflammation, optimising the gut microbiome will be a recommended preoperative management strategy for arthroplasty patients.Trial registration noACTRN12623001273673.

The effect of anesthesia methods on the neutrophil-lymphocyte ratio in patients undergoing forearm surgery: A monocentric and retrospective study.

Surgical trauma can induce systemic inflammation. The selected anesthesia method may modulate the inflammatory response and surgical results in the inflammatory process that occurs during surgical trauma. In this retrospective study, we aimed to compare the anti-inflammatory effects of general anesthesia and peripheral nerve block (infraclavicular block). Demographic, clinical, and laboratory records (hemogram, total leukocyte count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and mean platelet volume) were obtained from the archival data. The patients were divided into 2 groups: Group G, who received general anesthesia, and Group P, who received a peripheral nerve block (infraclavicular block) for forearm surgery. The amount of opioid consumed postoperatively was significantly lower in Group P. Infraclavicular block as an alternative to general anesthesia was found to be associated with a significant decrease in the neutrophil-to-lymphocyte ratio, total leukocyte count, and platelet-to-lymphocyte ratio levels compared to those observed after general anesthesia. Peripheral nerve blocks may play a role in reducing inflammation and alleviating stress.

Surgical Challenges and Outcomes in Management of Benign Retroperitoneal Germ Cell Tumors—A Tertiary Care Centre Experience

Surgical Challenges and Outcomes in Management of Benign Retroperitoneal Germ Cell Tumors—A Tertiary Care Centre Experience

Surgical and oncological outcome after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal mesothelioma : Aretrospective single center experience.

Peritoneal mesothelioma (PM) is arare disease with various histopathological subtypes. For malignant peritoneal mesothelioma and borderline subgroups locoregional therapy with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been implemented. The aim of our study was to retrospectively present the outcome after CRS and HIPEC for patients with different subtypes of peritoneal mesothelioma. In total 15patients received CRS and HIPEC due to peritoneal mesothelioma at our tertiary referral hospital between 2013 and 2022. Surgical and oncologic outcomes of 14 of those patients were retrospectively evaluated as one patient was lost to follow-up. The cohort consisted of 9patients with diffuse malignant peritoneal mesothelioma (64.3%), 3patients with multicystic peritoneal mesothelioma (21.4%) and 2patients with well-differentiated peritoneal mesothelioma (14.3%). Complete cytoreduction was possible in 85.7% (n = 12). The major complication rate was 28.6% (n = 4) and the reoperation rate was 14.3% (n = 2). Median follow-up was 55months (standard error, SE 15.0%, 95% confidence interval, CI 25.6-84.4 months). Over this time period 64.3% (n = 9) had no evidence of disease, 21.4% (n = 3) were alive with disease and 14.3% (n = 2) died of peritoneal mesothelioma. The median recurrence-free survival of patients was 13months (SE13.0%, 95% CI 0.0-32.2 months). None of the patients with multicystic peritoneal mesothelioma had evidence of disease at the time of last follow-up. Patients with peritoneal mesothelioma should receive locoregional treatment as good oncological results can be achieved with reasonable postoperative morbidity. Thus, awareness is necessary for this rare but potentially aggressive disease to offer the best medical care.

Short-term outcomes of 47 selective laparoscopic lymph node dissection for rectal cancer: A retrospective study.

This study aims to analyze the safety, feasibility, and short-term oncology outcomes of selective laparoscope lateral lymph node dissection (LLND) with total mesorectal excision surgery. Between December 2019 and May 2023, LLND with total mesorectal excision surgery was performed in 47 selected patients with advanced rectal cancer. Surgical complications and 2-year oncology survival outcomes were analyzed in the study. All 47 procedures were technically successful without converting conversion to open surgery. The mean operation time was 200.6 minutes (135-321 minutes), and the mean estimated blood loss was 92.9 mL (range 10-2000 mL). The most common postoperative complications were anastomotic (8.5%, n = 4), ileus (6.4%, n = 3), and chyle leakage (4.3%, n = 2). Lateral pelvic lymph node metastases were found in 19 (40.4%) patients. When divided into lateral pelvic lymph node positive and negative groups, there was no significant impact on overall survival (94.4% vs 100%, Log-rank P = .596) and local recurrence-free survival (LFRS) (76.7% vs 89.6%, Log-rank P = .210), except disease-free survival (DFS) (58.3% vs 90.2%, Log-rank P = .005). Subgroup analysis showed similar short-term survival outcomes between the pN+ group and the internal iliac metastasis group (Log-rank P of overall survival, LFRS, and DFS were all ˃.05). LRFS and DFS in the obturator or external iliac metastasis group were worse than those in the internal iliac metastasis group when the follow-up time was extended (Log-rank P of LFRS and DFS were .05 and .063). Selective laparoscopy LLND for rectal cancer is safety and feasibility, and its complications are manageable. Oncology survival outcomes for lateral pelvic lymph node metastases limited to the internal iliac are similar to the pN+ stage; therefore, it should be treated positively.

Revisiting the Surgical Outcomes of Non-Acute Subdural Hematomas among Retired Military Personnel : A Single Tertiary Hospital Retrospective Analysis in the Philippines.

Subdural hematomas (SDH) are classified clinically and/or radiologically as acute (ASDH), subacute (SSDH) and chronic (CSDH). The management differ depending on their classification, with only the ASDH having a definite accepted surgical guideline. Non-acute SDH, specifically SSDH and CSDH have no clear surgical guidelines but are managed similarly in some literature. This study was conducted to determine if there is a difference in outcomes among surgically managed non-acute SDH in a specific elderly population of retired military personnel. This is a pre-pandemic retrospective study that utilized data obtained from January 2016 to April 2019, in a subspecialty tertiary hospital that caters to retired military personnel or veterans, in the Philippines. After chart review and application of inclusion and exclusion criteria, twenty-one patients were included, all military retirees, with age 56 years old and above. Chart review and electronic database were retrieved to extract relevant information. In this study, a term 'mixed-type subdural hematoma' (MSDH) was proposed to encompass SDH that have mixed hypo-and-hyperdensity on preoperative CT scan and were subsequently found to have bright red liquefied hematoma instead of the classic engine machinery oil fluid found in a CSDH. Based on the observed cohort, 9 out of 11 CSDH patients attained the Glasgow Outcome Scale Extended (GOS-E) score of 8 while all the respondents in the MSDH group attained the same GOS-E score underscoring the need for early intervention in patients with non-acute subdural hematoma. Moreover, the outcomes of both MSDH and CSDH are comparable with low mortality rate (~9.5%) and immediate postoperative improvement (~90%). MSDH and CSDH, although classified separately using clinical and/or radiologic means, can collectively be categorized as a non-acute SDH and can be managed safely and effectively with burr hole surgery.

Impact of malnutrition on postoperative outcomes in total knee arthroplasty: a comprehensive analysis

Introduction: Malnutrition has been shown to cause perioperative complications, which can be particularly detrimental following total knee arthroplasty (TKA). These complications can lead to increased morbidity, extended hospital stays, and significant financial burdens on both patients and healthcare systems. To evaluate the nutritional status and body mass index (BMI) of patients undergoing TKA and monitor them for complications immediately postoperatively, at one week, and three months after surgery. Methods: This prospective study included 88 patients who underwent TKA at government medical college Kozhikode, Kerala, India. Nutritional status was assessed using serum albumin, ferritin, haemoglobin, and BMI (body mass index) levels. Patients were followed up for three months postoperatively to identify any complications. Data analysis was conducted to determine the relationship between malnutrition and postoperative complications. Results: Of the 88 patients, 5 developed major wound complications, with 4 of these patients exhibiting hypoalbuminemia. Hypoalbuminemia was found to have a statistically significant association with major wound complications (p<0.001). Malnutrition was associated with higher rates of major wound complications, increased need for postoperative blood transfusions, and longer hospital stays. Conclusion: Identifying modifiable risk factors such as malnutrition in patients undergoing TKA is crucial for reducing the risk of postoperative complications, which can otherwise lead to disastrous outcomes. Preoperative optimization of nutritional status can significantly improve surgical outcomes and reduce complications.

Comparison of diagnostic yields, operative times, and post-operative hemorrhage between twist drill versus burr hole craniotomy approaches for stereotactic needle brain biopsy.

Stereotactic frameless needle brain biopsy is a common neurosurgical procedure performed via twist drill or open burr hole approaches. We aim to compare diagnostic yields and surgical outcomes to delineate the safety and efficacy of both approaches. A retrospective database of all stereotactic needle biopsy procedures performed at a single institution over 30 months was conglomerated. Demographics, medical comorbidities, operative details/complications, immediate post-operative imaging, and pathology were abstracted. Two hundred and twenty-five needle biopsies were identified, of which 165 (73.3%) were open, and 60 (26.7%) were twist drill. Diagnostic pathology yield rates between open (84.8%) and twist drill (93.3%) approaches were similar (p = 0.15), with a median of 4 cores taken in each (p = 0.30). Diagnostic tissue yields with an intra-operative pause for pathology confirmation was 90.4% compared to 79.1% without pause (p = 0.036, OR 2.49). Median operative times for open versus twist drill procedures were 68.0min (IQR 49-83) versus 35.5min (IQR 26-54), respectively (Wilcoxon p < 0.001), which remained significant after controlling for awaiting intraoperative pathology using bivariable linear modeling (p < 0.001). Intraoperative bleeding through the needle cannula was noted in 22 patients (9.8%), including eight twist drill (13.3%) and 14 open needles (8.5%). Of 197 cases (87.6%) with post-operative cranial imaging (CT/MRI), 90 (45.7%) demonstrated some degree of post-operative hemorrhage characterized as superficial (n = 10, 11.1%), deep/intralesional (n = 64, 71.1%) bleeding, or both (n = 16, 17.9%). Bleeding rates between open (46.7%) and twist drill (43.3%) approaches were similar (p = 0.78). Post-operative clinical decline or neurological change was noted in 9 patients (4.0%), including one twist drill (1.7%) and eight open needles (4.8%), among which 7 (78%) had deep blood products identified on post-operative imaging. Stereotactic needle biopsy via twist drill approach has similar diagnostic yield rates, asymptomatic bleeding rates, and post-operative complications with significantly shorter operative time and smaller incision size than conventional open burr hole needle biopsy. Using intra-operative frozen histopathology for presumed sufficient diagnostic tissue may improve final pathologic diagnostic rates regardless of approach technique.

Clinical significance of upper arm motor nerve conduction velocity in cubital tunnel syndrome

Background Retrograde denervation occurs in severe entrapment neuropathy. This study aimed to investigate changes in motor nerve conduction velocity (MNCV) at the upper arm, specifically proximal to the elbow, in cubital tunnel syndrome (CuTS) and to correlate these changes with preoperative severity and postoperative outcomes. Methods We retrospectively reviewed 95 elbows with 81 patients with CuTS for preoperative severity, and then 67 elbows with 60 of these patients who underwent anterior subcutaneous transposition surgery for postoperative outcome, classified into favorable and unfavorable groups according to Messina grade. Results The reduction of upper arm MNCV was correlated with aging, decreased compound muscle action potentials of abductor digiti minimi muscle, loss of sensory nerve action potentials, and modified McGowan grade. Postoperative assessment revealed lower MNCV values in the “unfavorable” group compared to the “favorable” group at 1 month, 6 months, and the last follow up. At each time point, the optimal cut-off value of upper arm MNCV for predicting postoperative outcomes was 54.1 m/s. Discussion Upper arm MNCV might be a useful predictor of poor surgical outcome. Ulnar nerve MNCV at the upper arm should be measured alongside routine assessment of MNCV at the elbow and forearm, especially in clinically severe cases considering surgery.

Outcomes of Elongated Styloid Process Syndrome Treated with Minimally Invasive Cervical Styloidectomy (MICS)—A Single-Center Retrospective Study

Background: Stylohyoid syndrome, also known as classical Eagle syndrome (ES), is a rare condition characterized by elongation of the styloid process (SP) or calcification of the stylohyoid chain, presenting numerous non-specific symptoms. Most papers concerning this rare condition are case reports, case studies, or retrospective studies. This retrospective study delves into the intricacies of Eagle syndrome and evaluates surgical outcomes in patients treated with minimally invasive cervical styloidectomy (MICS). Methods: We conducted a retrospective study of patients treated due to ES between September 2021 and August 2023. Ninety-seven patients were qualified for MICS. Evaluation before and after surgical treatment was conducted during follow-up visits and by a questionnaire that included various data, such as symptoms, pain intensity, evaluation of healing period, and overall patient satisfaction. The minimum follow-up period was six months. Results: After applying inclusion and exclusion criteria, eighty-four patients were qualified for further assessment. The most common symptoms that subsided completely after treatment were pharyngeal foreign body sensation and pain with dysphagia or odynophagia. The MICS procedure proved to be highly effective, with 94.2% of patients experiencing a significant reduction in pain intensity and 97.1% reporting overall success. All patients were satisfied with the aesthetic outcome of the scar. The length of SP and time onset from the first symptoms to treatment positively correlated with the number, intensity, and time required for symptoms to subside. Conclusions: Eagle syndrome should be considered in diagnosing patients with orofacial and cervical pain symptoms, as the time from occurrence of the first symptoms to treatment is crucial. MICS is highly effective and has a low rate of complications in treating ES. Potential scar formation should not be a significant factor when deciding between the intraoral and external approaches.

Outcome of posterior decompression by L1 laminectomy, transpedicular fixation, posterolateral fusion in burst fracture L1 with incomplete spinal cord injury

Introduction: Burst fractures are more severe than compression fractures as the bones spread out in all directions and may damage the spinal cord, leading to paralysis or nerve injury. This study aims to find the surgical outcomes of Posterior Decompression by L1 Laminectomy in terms of burst fracture with incomplete spinal cord injury. Methods: 48 adult patients with burst fractures with incomplete spinal injury came to NITR from June 2023 to May 2024. In this non-randomized clinical trial, the outcomes of decompression by L1 laminectomy were analysed by using the canal encroachment ratio, while deformity correction was assessed using the sagittal Cobb angle and the percentage of anterior vertebral height for the treatment of L1 burst fracture with incomplete spinal cord injury. Results: The patients were followed up for an average of 12 months. The mean operation time was 154.53 minutes, mean intraoperative blood loss of 48.84 mL, and the mean incision length was 7.78 cm. The canal encroachment ratio decreased significantly, as well as the sagittal Cobb angle, and anterior vertebral percentage height increased. Oswestry Disability Index, and American Spinal Injury Association impairment scale classification were significant. Conclusions: Posterior decompression combined with Transpedicular Fixation and Posterolateral Fusion in the treatment of Burst Fracture L1 with Incomplete Spinal Cord Injury is safe and effective.

"Folding Fan Flap": A Novel and Dependable Surgical Technique for Crow's Feet Correction by Z-Plasty of Orbicularis Oculi Muscle.

The challenge of crow's feet surgical correction is to minimize the complication caused by orbicularis oculi muscle (OOM) resection while ensuring the operative effect. This study aims to propose a novel technique to solve this problem and evaluate its efficacy. From January 2022 to April 2024, all patients who received "Folding fan flap" in our institution were included. The outer third of the OOM below the lateral canthus was dissected and received Z-plasty to exchange width for length and reconstruct the muscle dynamics in a non-circular direction. Preoperative and postoperative smiling crow's feet were assessed by two independent physicians using the Lemperle wrinkle scale. At least six months after surgery, patient satisfaction with wrinkle correction, naturalness of facial expression, and local flattening was subjectively evaluated on a five-point scale. Complications including hematomas, incomplete eyelid closure, facial stiffness, and forehead numbness were recorded. A total of 32 patients (63 sides) were included with a mean follow-up of 13.9 ± 5.2 months. Postoperative assessments showed a significant reduction in Lemperle's score from 4.8 ± 0.4 to 1.5 ± 0.5 (P=0.000). Regarding the satisfaction of surgical outcomes and the naturalness of facial expressions, thirty patients (93.8%) were very satisfied. There were no severe complications such as hematomas and incomplete eyelid closure. Preliminary clinical studies demonstrated the efficacy of this technique in ensuring outcomes while preserving normal dynamic expressions. By Z-plasty of the outer circle of OOM, the muscle dynamic was successfully modified rather than eradicated. This journal requires that authors assign a level of evidence to each article.

Surgical outcomes of inverted internal limiting membrane flap technique for primary rhegmatogenous retinal detachment coexisting with a macular hole.

This retrospective study aimed to evaluate the visual outcomes and foveal restoration in eyes with rhegmatogenous retinal detachment (RRD) and macular hole (MH) following surgery using the inverted internal limiting membrane (ILM) flap technique. We collected data on eyes with coexisting RRD and MH that underwent surgery using the inverted ILM flap technique between January 2016 and December 2018. The primary outcome measures were visual acuity (VA) and optical coherence tomography findings. Of 308 eyes with MH originating from various causes, 8 (2.6%) eyes diagnosed with coexisting RRD and MH treated using the inverted ILM flap technique were included. The average patient age and axial length were 65.00 ± 12.01 years and 23.66 ± 0.77 mm, respectively. The mean preoperative best-corrected VA (BCVA) was 1.84 (spherical equivalent [SE], counting finger) ± 0.32 logMAR and the mean final BCVA had improved significantly to 1.05 (SE, 20/223) ± 0.67 logMAR (P = .017). The primary retinal reattachment, MH closure, and secondary retinal attachment rates were 75% (6/8), 87.5% (7/8), and 100% (7/7), respectively. The inverted ILM flap technique led to significant improvements in anatomical and visual outcomes in patients with coexisting RRD and MH.

Anthropometric predictors of hamstring graft size in anterior cruciate ligament reconstruction

Background: The anterior cruciate ligament (ACL) is commonly injured in the knee joint, necessitating surgical reconstruction where quadrupled hamstring tendon autografts are frequently utilized for their favourable outcomes. Predicting the appropriate dimensions of these grafts is essential for surgical success. This study aims to investigate whether simple anthropometric measurements-height, weight, body mass index (BMI), thigh length, and circumference-can predict the length and diameter of quadrupled hamstring tendons used in ACL reconstruction. Methods: This cross-sectional study included 45 patients undergoing ACL reconstruction with quadrupled hamstring autografts at department of orthopaedics, Renai Medicity Kerala, India. Preoperative anthropometric measurements were correlated with intraop graft dimensions using Pearson correlation and SPSS statistical software (version 22). Results: Taller patients exhibited a positive correlation with graft diameter (p=0.028). Height and thigh length correlated positively with both gracilis and semitendinosus tendon lengths (p&lt;0.001). Thigh circumference correlated positively with semitendinosus length (p=0.005), while weight, BMI, and other measures did not significantly correlate with graft dimensions. Conclusions: Anthropometric measurements, particularly height and thigh length, serve as valuable predictors for hamstring graft dimensions in ACL reconstruction. These findings may assist surgeons in selecting appropriate grafts and optimizing surgical outcomes.

Evaluation of Surgical Outcomes and Patient-reported Outcomes of Eyebrow Defect Repair with "Kite Flap".

There is no consensus on the surgical options for repairing mild-to-moderate eyebrow defects due to burns, trauma, and skin tumors, and the outcome of the surgery is unclear. In this study, the authors evaluated the surgical outcomes and patient-reported outcomes of eyebrow defect repair with the "kite flap" in a cross-sectional study. Case data and imaging data of twelve patients with eyebrow defects undergoing repair from July 2018 to June 2021 were retrospectively analyzed, and the surgical outcomes were statistically analyzed by the Face-Q subjective evaluation scale and the surgical objective evaluation scale. In the postoperative objective evaluation, 66.67% of the patients were "very satisfied," and the scores of the Face-Q scale for the assessment of appearance and psychosocial function were significantly improved compared with those of the preoperative period, with a statistically significant difference in the data changes (P<0.05). The study showed that the "kite flap" is an excellent surgical method for repairing mild-to-moderate defects of the eyebrow, and it can meet the requirements of both function and appearance after surgery.

Conventional vaginal approach vs. transvaginal natural orifice transluminal endoscopic surgery for treating apical prolapse, a randomized controlled study

ObjectiveVaginal hysterectomy combined with uterosacral suspension (USLS) is a technique for treating pelvic organ prolapse. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) has been described as an alternative minimal invasive approachfor treating various gynecological and non-gynecological pathologies. The aim was to compare the surgical time between conventional vaginal hysterectomy combined with USLS and vNOTES hysterectomy combined with USLS. Study designMulti-center randomized controlled trial performed 2019–2021 at Rambam Health Care Campus (Israel) and Imelda Hospital (Belgium). Thirty women underwent vNOTES procedures and 30 women underwent conventional vaginal procedures. The primary outcome was total surgical time. Secondary outcomes included hysterectomy time, USLS time, intraoperative bleeding, length of hospitalization, pain during the first 24 h postoperative, the need of analgesia, intraoperative and postoperative adverse events, and patient-reported outcomes questionnaires. Parametric statistical methods were used to analyze the data. ResultsCompared to conventional vaginal procedures, vNOTES procedures were shorter in total surgical time (77 vs. 93 min, p = 0.004), hysterectomy time (26 vs 33 min, p < 0.001), and USLS time (20 vs 26 min. p = 0.02). Blood loss was higher in conventional vaginal compared to vNOTES surgery, as reflected by the mean blood loss estimate (143 vs 60 ml. p < 0.001) and the delta-hemoglobin (pre-operation minus the post-operation hemoglobin level (1.8 vs 1.2 ml/dL, p = 0.01). There was no difference between the groups regarding analgesics used, postoperative pain, surgical objective outcomes, and scores on patient-reported outcomes questionnaires. Adverse events were significantly more frequent in the conventional vaginal group than in the vNOTES group (p < 0.001 for intraoperative events and p = 0.05 for events that occurred in the follow-up time interval). ConclusionvNOTES hysterectomy with USLS has lower surgical times than conventional vaginal hysterectomy with USLS, lower blood loss and less adverse events. Other surgical objective and subjective outcomes were similar between the approaches.
