National centralization of Hirschsprung's disease in Sweden: a comparison of postoperative outcome.

BACKGROUND: In Sweden, surgical treatment of Hirschsprung's disease (HSCR) was centralized from four to two pediatric surgery centers 1st of July 2018. In adults, centralization of surgical care for complex or rare diseases seems to improve quality of care. There is little evidence supporting centralization of pediatric surgical care. The aim of this study was to assess surgical management and postoperative outcome in HSCR patients following centralization of care. METHODS: This study retrospectively analyzed data of patients with HSCR that had undergone pull-through at a pediatric surgery center in Sweden from 1st of July 2013 to 30th of June 2023. Patients managed from 1st of July 2013 to 30th of June 2018 (before centralization) were compared with patients managed from 1st of July 2018 to 30th of June 2023 (after centralization) regarding surgical treatment, unplanned procedures under general anesthesia or readmissions up to 90 days after pull-through as well as complications classified according to Clavien-Madadi up to 30 days after pull-through. RESULTS: In the 5-year period prior to centralization, 114 individuals from 4 treating centers were included and compared to 83 patients from 2 treating centers in the second period. There was no difference regarding age at pull-through or proportion of patients with a stoma prior to pull-through. An increase of laparoscopically assisted endorectal pull-through (8.8% to 39.8%) was observed (p < 0.001). No significant differences were seen in postoperative hospital stay, unplanned procedures under general anesthesia, or readmissions up to 90 days after pull-through. There was no difference in severe complications (Clavien-Madadi ≥ 3); however, HAEC treated with antibiotics increased following centralization (10.5-24.1%; p = 0.018). CONCLUSION: Centralization of care for HSCR does not seem to delay time to pull-through nor reduce severe complications, unplanned procedures under general anesthesia or readmissions up to 90 days after pull-through. The increased HAEC rate may be due to increased awareness of mild HAEC. LEVEL OF EVIDENCE:  Level III.

Surgical management of pancreatic neoplasms in children: a single-institution experience over 15 years.

Introduction: Pancreatic neoplasms are rare among children and very few studies have reported on surgical outcomes for pediatric pancreatic neoplasms. Therefore, we aimed to describe patient and tumor characteristics and report on the surgical outcomes of pediatric pancreatic neoplasm. Methods: In this retrospective single-center study, we reviewed and analyzed the data of patients who underwent surgery for pediatric pancreatic neoplasms at Severance Children's Hospital between January 2007 and December 2022. Clinical data including demographics, surgical procedures, and postoperative and long-term outcomes were evaluated. Results: A total of 28 patients underwent surgical treatment for pancreatic neoplasms with a median age of 11.7 years (range: 0.4-17.8). The most common histological diagnosis among benign tumors was solid pseudopapillary neoplasm (SPN), which occurred in 20 patients (71.4%). This was followed by a mucinous cyst, nesidioblastosis, pseudocyst, duplication cyst, and benign cyst, each occurring in one patient (3.5%). Regarding malignant tumors, pancreatoblastoma, solid pseudopapillary carcinoma, and malignant pheochromocytoma were noted in one patient each (3.5%). Tumor locations included the head in 4 patients (14.2%), the body in 7 (25%), and the tail in 16 (57.1%), and was diffuse in 1 (3.5%). The most common surgical resection range was distal pancreatectomy, found in 22 patients (78.5%), followed by pylorus-preserving pancreaticoduodenectomy, found in 2 (7.2%); duodenum-preserving pancreatic resection, central pancreatectomy, tumor enucleation, and near-total pancreatectomy were performed in one patient each (3.5%). Overall, 4 patients developed grade B or C postoperative pancreatic fistulas, and 1 experienced postoperative mortality due to uncontrollable bleeding. The mean follow-up period was 6.1 years (range: 1-15.6 years), during which no significant impact on growth after surgery was detected. Among the 20 patients with SPN, tumor rupture occurred in 4 (20%), among whom 2 experienced tumor recurrences. Conclusions: Histological diagnosis of benign tumors was predominant in this case series and various extents of surgical resection were performed. Surgical treatment for pediatric pancreatic neoplasms appears to be safe and effective. However, considering the long-term prognosis of these patients, it is essential to determine the appropriate extent of surgical resection based on the location of the tumor.

Secured Anatomy-driven Flap Extension (SAFE) for Guided Bone Regeneration: A Modified Flap Release Technique Description and Retrospective Study.

INTRODUCTION: Current flap-releasing designs for guided bone regeneration (GBR) emphasize preserving subperiosteal microvasculature by adapting a deep slit approach, separating theperiosteum from the flap. While biologically sound, a biomechanical disadvantage may be encountered. This study aimed to describe a modified design, the Secured Anatomy-driven Flap Extension (SAFE) technique, for effective facial flap release and to preliminarily evaluate the clinical outcomes of this technique retrospectively. MATERIALS AND METHODS: Chart reviews were conducted to identify patients treated by facial flap release in staged GBR procedures between May 2020 and March 2022. The anatomical, biological, and biomechanical rationale of this technique were described. The following clinical data were collected: intraoperative and postoperative complications, initial and final horizontal ridge width before and 5-6 months after the GBR, and implant performance. RESULTS: A total of 10 patients were identified. At baseline, these patients presented with a mean ridge width of 2.05 ± 0.52 mm. No intraoperative and postoperative complications were observed in these patients (bleeding, wound opening, neurosensory disturbance, etc.) at the 2-3-week follow-up visit. At the re-entry, a mean ridge width of 6.50 ± 0.55 mm was measured (p < 0.01), resulting in a mean of 4.45 ± 0.65 mm ridge width gain. Twenty-one implants were successfully placed, integrated, and in function without signs/symptoms of peri-implantitis after a mean 21.5 ± 9.2 months follow-up period. CONCLUSION: Preliminary results suggest that the SAFE technique is a safe and predictable approach for releasing facial flaps during GBR procedures.

Intraocular Pressure-Lowering Effect of Intraocular Lens Refixation in Patients with Elevated Intraocular Pressure Due to Intraocular Lens Subluxation.

Background and Objectives: To evaluate the surgical outcomes of intraocular lens (IOL) refixation with vitrectomy in patients with elevated intraocular pressure (IOP) due to IOL subluxation. Materials and Methods: Patients with elevated IOP due to IOL subluxation who had undergone IOL refixation with vitrectomy between 1 June 2013 and 31 December 2023 were retrospectively evaluated. The primary outcome measure was surgical success or failure. Surgical success was defined as a reduction of ≥20% in the preoperative IOP or IOP ≤ 21 mmHg (criterion A), IOP ≤ 18 mmHg (criterion B), or IOP ≤ 15 mmHg (criterion C). Reoperation, loss of light perception, and hypotony were considered as surgical failure. The IOP, number of glaucoma medications used, postoperative complications, and visual acuity were evaluated as the secondary outcomes. The surgical outcomes were compared between the glaucoma and ocular hypertension (OH) groups. Results: At 12 months postoperatively, the probability of success was 72.5%, 54.1%, and 28.4% using criterion A, B, and C, respectively, and the mean IOP and mean number of glaucoma medications used had decreased significantly (p < 0.01 and p = 0.03, respectively). Furthermore, the cumulative success rate was significantly higher in the OH group than in the glaucoma (100% vs. 47.4%; p < 0.01) when using criterion A. Additional glaucoma surgery was required only in the glaucoma group. Conclusions: IOL refixation surgery significantly decreases the IOP and number of glaucoma medications required in patients with elevated IOP due to IOL subluxation. Thus, IOL refixation surgery alone without glaucoma surgery might be effective as the primary procedure in such patients.

An Analysis of Emergency Surgical Outcomes for Pediatric Traumatic Brain Injury: A Ten-Year Single-Institute Retrospective Study in Taiwan.

Background and Objectives: Pediatric traumatic brain injury (pTBI) remains a major pediatric public health problem, despite well-developed injury prevention programs. The purpose of this study is to analyze the emergency surgical outcomes of pTBI in a single institute ten-year retrospective study to offer a real-world clinical result. Materials and Methods: Our institute presented a clinical retrospective, single-institute research study of 150 pediatric TBI cases that were diagnosed and underwent emergency surgical treatment from 2010 to 2019. Results: The incidence of radiological findings is detailed as follows: brain edema (30%, 45/150), followed by acute subdural hematoma (27.3%, 41/150), epidural hematoma (21.3%, 32/150), chronic subdural hemorrhage (10%, 15/150), skull fracture (6.7%, 10/150), and traumatic subarachnoid hemorrhage (4.7%, 7/150). Surgical intervention data revealed that decompressive craniectomy was still the main effective surgical method. The results showed longer hospital stays and higher morbidity rates in the brain edema, acute subdural hematoma, and chronic subdural hemorrhage groups, which were viewed as poor surgical outcome groups. Epidural hematoma, skull fracture and traumatic subarachnoid hemorrhage were categorized into good surgical outcome groups. Notably, the data revealed gross improvement in Glasgow Coma Scale/Score (GCS) evolution after surgical interventions, and the time to cranioplasty was a significant factor in the development of post-traumatic hydrocephalus (PTH). Conclusions: Our study provided real-world data for the distribution of etiology in pTBI and also categorized it into six groups, indicating disease-orientated treatment. In addition, our data supported that decompressive craniectomy (DC) remains a mainstay surgical treatment in pTBI and early cranioplasty could decrease the incidence of PTH.

The modified Whitaker test in evaluating the surgical effect after ileal ureter replacement.

PURPOSE: To develop a novel adaptation of the Whitaker test for assessing the surgical effects of ileal ureter replacement (IUR), and to evaluate its feasibility and effect in the postoperative evaluation. PATIENTS AND METHODS: From November 2021 to September 2023, patients undergoing the modified Whitaker test following IUR were prospectively enrolled. The relative pressure was defined as the pelvis pressure minus the bladder pressure. Successful nephrostomy removal was defined as absence of symptoms and improved or stable hydronephrosis. RESULTS: The 51 ureters from 39 patients underwent the modified Whitaker test after IUR. The modified Whitaker test was performed successfully on all patients without any reported discomfort. The relative pressure of 47 ureters kept steady (< 15 cmH2O) throughout the examination with well ileal ureter peristalsis and was classified into type I. The relative pressure of 2 ureters increased with perfusion reaching a range of 15-22 cmH2O, with well ileal ureteral peristalsis observed (type II). The relative pressure of 2 ureters increased along with perfusion, with weakening of ileal ureter peristalsis or a leakage of contrast medium, and the relative pressure surpassed 22 cmH2O (type III). Nephrostomy tubes were promptly removed for type I and type II ureters, while removal for type III ureters occurred after a 2-month period. None of the 39 patients required additional interventions for recurrent obstruction. CONCLUSION: The modified Whitaker test was a safe and effective approach for the evaluation of surgical effects of IUR, offering additional evidence to assess the safety of nephrostomy tube removal.

Machine learning algorithm for predicting seizure control after temporal lobe resection using peri-ictal electroencephalography.

Brain resection is curative for a subset of patients with drug resistant epilepsy but up to half will fail to achieve sustained seizure freedom in the long term. There is a critical need for accurate prediction tools to identify patients likely to have recurrent postoperative seizures. Results from preclinical models and intracranial EEG in humans suggest that the window of time immediately before and after a seizure ("peri-ictal") represents a unique brain state with implications for clinical outcome prediction. Using a dataset of 294 patients who underwent temporal lobe resection for seizures, we show that machine learning classifiers can make accurate predictions of postoperative seizure outcome using 5 min of peri-ictal scalp EEG data that is part of universal presurgical evaluation (AUC 0.98, out-of-group testing accuracy > 90%). This is the first approach to seizure outcome prediction that employs a routine non-invasive preoperative study (scalp EEG) with accuracy range likely to translate into a clinical tool. Decision curve analysis (DCA) shows that compared to the prevalent clinical-variable based nomogram, use of the EEG-augmented approach could decrease the rate of unsuccessful brain resections by 20%.

Robotic-assisted versus conventional laparoscopic surgery for endometrial cancer: long-term results of a randomized controlled trial.

BACKGROUND: Robotic-assisted laparoscopy has become a widely and increasingly used modality of minimally invasive surgery in the treatment of endometrial cancer. Due to its technical advantages, robotic-assisted laparoscopic surgery offers benefits, such as a lower rate of conversions compared to conventional laparoscopy. Yet, data on long-term oncological outcomes after robotic-assisted laparoscopy is scarce and based on retrospective cohort studies only. OBJECTIVE: This study aimed to assess overall survival, progression-free survival, and long-term surgical complications in patients with endometrial cancer randomly assigned to robotic-assisted or conventional laparoscopy. STUDY DESIGN: This randomized controlled trial was conducted at the Department of Gynecology and Obstetrics of Tampere University Hospital, Finland. Between 2010 and 2013, 101 patients with low-grade endometrial cancer scheduled for minimally invasive surgery were randomized preoperatively 1:1 either to robotic-assisted or conventional laparoscopy. All patients underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy. A total of 97 patients (49 in the robotic-assisted laparoscopy group and 48 in the conventional laparoscopy group) were followed up for a minimum of 10 years. Survival was analyzed using Kaplan-Meier curves, log-rank test, and Cox proportional hazard models. Binary logistic regression analysis was used to analyze risk factors for trocar site hernia. RESULTS: In the multivariable regression analysis, overall survival was favorable in the robotic-assisted group (hazard ratio 0.39; 95% confidence interval [CI], 0.15-0.99, P=.047) compared to the conventional laparoscopy group. There was no difference in progression-free survival (log-rank test, P=.598). The 3-, 5-, and 10-year overall survival were 98.0% (95% CI, 94.0-100) vs 97.9% (93.8-100), 91.8% (84.2-99.4) vs 93.7% (86.8-100), and 75.5% (64.5-87.5) vs 85.4% (75.4-95.4) for the conventional laparoscopy and the robotic-assisted groups, respectively. Trocar site hernia developed more often for the robotic-assisted group compared to the conventional laparoscopy group 18.2% vs 4.1% (odds ratio 5.42, 95% CI, 1.11-26.59, P=.028). The incidence of lymphocele, lymphedema, or other long-term complications did not differ between the groups. CONCLUSION: The results of this randomized controlled trial suggest a minor overall survival benefit in endometrial cancer after robotic-assisted laparoscopy compared to conventional laparoscopy. Hence, the use of robotic-assisted technique in the treatment of endometrial cancer seems safe, though larger randomized controlled trials are needed to confirm any potential survival benefit. No alarming safety signals were detected in the robotic-assisted group since the rate of long-term complications differed only in the incidence of trocar site hernia.

Exploring Pathways for Pain Relief in Treatment and Management of Lumbar Foraminal Stenosis: A Review of the Literature.

BACKGROUND: Lumbar foraminal stenosis (LFS) involves the narrowing of neural foramina, leading to nerve compression, significant lower back pain and radiculopathy, particularly in the aging population. Management includes physical therapy, medications and potentially invasive surgeries such as foraminotomy. Advances in diagnostic and treatment strategies are essential due to LFS's complexity and prevalence, which underscores the importance of a multidisciplinary approach in optimizing patient outcomes. METHOD: This literature review on LFS employed a systematic methodology to gather and synthesize recent scientific data. A comprehensive search was conducted across PubMed, Scopus and Cochrane Library databases using specific keywords related to LFS. The search, restricted to English language articles from 1 January 2000 to 31 December 2023, focused on peer-reviewed articles, clinical trials and reviews. Due to the heterogeneity among the studies, data were qualitatively synthesized into themes related to diagnosis, treatment and pathophysiology. RESULTS: This literature review on LFS analyzed 972 articles initially identified, from which 540 remained after removing duplicates. Following a rigorous screening process, 20 peer-reviewed articles met the inclusion criteria and were reviewed. These studies primarily focused on evaluating the diagnostic accuracy, treatment efficacy and pathophysiological insights into LFS. CONCLUSION: The comprehensive review underscores the necessity for precise diagnostic and management strategies for LFS, highlighting the role of a multidisciplinary approach and the utility of a unified classification system in enhancing patient outcomes in the face of this condition's increasing prevalence.

Network excitability of stimulation-induced spectral responses helps localize the seizure onset zone.

OBJECTIVE: While evoked potentials elicited by single pulse electrical stimulation (SPES) may assist seizure onset zone (SOZ) localization during intracranial EEG (iEEG) monitoring, induced high frequency activity has also shown promising utility. We aimed to predict SOZ sites using induced cortico-cortical spectral responses (CCSRs) as an index of excitability within epileptogenic networks. METHODS: SPES was conducted in 27 epilepsy patients undergoing iEEG monitoring and CCSRs were quantified by significant early (10-200 ms) increases in power from 10 to 250 Hz. Using response power as CCSR network connection strengths, graph centrality measures (metrics quantifying each site's influence within the network) were used to predict whether sites were within the SOZ. RESULTS: Across patients with successful surgical outcomes, greater CCSR centrality predicted SOZ sites and SOZ sites targeted for surgical treatment with median AUCs of 0.85 and 0.91, respectively. We found that the alignment between predicted and targeted SOZ sites predicted surgical outcome with an AUC of 0.79. CONCLUSIONS: These findings indicate that network analysis of CCSRs can be used to identify increased excitability of SOZ sites and discriminate important surgical targets within the SOZ. SIGNIFICANCE: CCSRs may supplement traditional passive iEEG monitoring in seizure localization, potentially reducing the need for recording numerous seizures.

Surgical outcomes of a congenital nystagmus family with a missense mutation in the FRMD7 gene.

Background: This study aimed to assess the effectiveness of surgery in the management of vertical compensatory head posture in patients with congenital nystagmus (CN) inherited in an X-linked manner in a Chinese family and determine the molecular pathogenesis of this disease. Methods: We studied 18 members belonging to four generations in a family with congenital nystagmus. Parks shift of neutral zone surgeries were performed on 7 patients with vertical compensatory head posture from the family. In addition, head posture, visual acuity, and stereopsis of the 7 patients were evaluated before and 2-years after the displacement surgeries. Gene alternations of the disease were researched by sequencing a candidate gene (FRMD7). From each generation of the family, one patient (including the proband) and one normal control were sampled for Sanger sequencing. Results: Over a median follow-up period of 2 years, the anomalous head posture, visual acuity, and stereopsis significantly improved postoperatively (P < 0.05). Sanger sequencing revealed that a variant c.586G > T (p.D196Y) in exon 7 of FRMD7 was co-segregated with the disease in this family. Conclusions: Parks shift of neutral zone surgeries relieved the vertical compensatory head posture and improved visual acuity and stereopsis in the primary position of CN patients. In this study, it was concluded that a missense mutation in exon 7 (c.586G > 7, p.D196Y) in FRMD7 was possibly responsible for the disease in this family.

Surgical Outcome After Distal Pancreatectomy With and Without Portomesenteric Venous Resection in Patients with Pancreatic Adenocarcinoma: A Transatlantic Evaluation of Patients in North America, Germany, Sweden, and The Netherlands (GAPASURG).

BACKGROUND: Pancreatic adenocarcinoma located in the pancreatic body might require a portomesenteric venous resection (PVR), but data regarding surgical risks after distal pancreatectomy (DP) with PVR are sparse. Insight into additional surgical risks of DP-PVR could support preoperative counseling and intraoperative decision making. This study aimed to provide insight into the surgical outcome of DP-PVR, including its potential risk elevation over standard DP. METHODS: We conducted a retrospective, multicenter study including all patients with pancreatic adenocarcinoma who underwent DP ± PVR (2018-2020), registered in four audits for pancreatic surgery from North America, Germany, Sweden, and The Netherlands. Patients who underwent concomitant arterial and/or multivisceral resection(s) were excluded. Predictors for in-hospital/30-day major morbidity and mortality were investigated by logistic regression, correcting for each audit. RESULTS: Overall, 2924 patients after DP were included, of whom 241 patients (8.2%) underwent DP-PVR. Rates of major morbidity (24% vs. 18%; p = 0.024) and post-pancreatectomy hemorrhage grade B/C (10% vs. 3%; p = 0.041) were higher after DP-PVR compared with standard DP. Mortality after DP-PVR and standard DP did not differ significantly (2% vs. 1%; p = 0.542). Predictors for major morbidity were PVR (odds ratio [OR] 1.500, 95% confidence interval [CI] 1.086-2.071) and conversion from minimally invasive to open surgery (OR 1.420, 95% CI 1.032-1.970). Predictors for mortality were higher age (OR 1.087, 95% CI 1.045-1.132), chronic obstructive pulmonary disease (OR 4.167, 95% CI 1.852-9.374), and conversion from minimally invasive to open surgery (OR 2.919, 95% CI 1.197-7.118), whereas concomitant PVR was not associated with mortality. CONCLUSIONS: PVR during DP for pancreatic adenocarcinoma in the pancreatic body is associated with increased morbidity, but can be performed safely in terms of mortality.

Nasolacrimal duct rhinostomy for low-level nasolacrimal duct obstruction:long-term outcomes and surgical selection paradigm.

PROPOSE: This study aims to present long-term outcomes in a specific patient population experiencing epiphora due to low-level nasolacrimal duct obstruction (NLDO) following endonasal endoscopic nasolacrimal duct rhinostomy, and to propose a surgical selection paradigm for varying locations of NLDO. METHODS: Between September 1, 2017 and February 28, 2023, a retrospective analysis was conducted on 26 patients diagnosed with primary acquired nasolacrimal duct obstruction (PANDO) who underwent endonasal endoscopic nasolacrimal duct rhinostomy for low-level NLDO (defined as obstruction below the plane of the superior border of the inferior turbinate attachment). The study assessed surgical success through objective measures of anatomical patency and subjective measures of functional patency during a postoperative follow-up period of at least six months. Additionally, any complications that arose during this follow-up period were documented. RESULTS: The study included a cohort of 26 patients, consisting of 24 women and 2 men, with a mean age of 47.58 ± 3.09 years (range: 8-75). All patients underwent endoscopic nasolacrimal duct rhinostomy, with 10 eyes having previously undergone tear duct recanalization procedures. Anatomical patency was achieved in 88.5% (23/26) of cases, while functional patency was achieved in 80.8% (21/26) after an average follow-up period of 41.9 ± 22.1 months. No significant complications were observed in any of the patients during the follow-up period. CONCLUSION: Endonasal endoscopic nasolacrimal duct rhinostomy is effective in treating epiphora in over 80% of cases with low-level NLDO. Tailoring the surgery to the location of the obstruction can improve outcomes and minimize damage.

The patients' perspective: cut off points for satisfaction in pharmacological therapy and surgical outcomes.

Background: This article presents the results of a pilot study investigating patients' satisfaction thresholds for pharmacological outcomes versus surgical outcomes. Materials and methods.: A total of 150 participants were presented with two hypothetical scenarios depicting either pharmacological therapy or surgical interventions. Each scenario described a potential outcome, from a 10% clinical improvement (value 10) to a 100% clinical improvement (value 100) and asked participants to indicate the satisfactory level they would find acceptable. Conclusions: The results revealed distinct patterns in satisfaction thresholds between the two treatment modalities. Between the 150 participants, 52,7% were male and 47,3% female. We also identified a total of 28,8% whom were healthcare workers. Overall, the results for the pharmacological therapy outcomes observed a mean of 60,88 with a standard deviation of 22,77, a median of 60 and a mode of 70; while for the surgical outcomes the mean was 67,81 with a standard deviation of 23,03, the median 85 and the mode 80. We also observed that for the pharmacological therapy outcomes healthcare workers had a lower satisfactory cut off compared to non-healthcare workers. Another interesting finding was that for pharmacological therapy outcomes individuals under 50 y/o had a higher satisfactory cut off compared to individuals over 50 y/o, while for the surgical outcomes we got opposite results. Overall, the findings of this pilot study, even if limited, demonstrated higher minimum satisfaction expectations for surgical outcomes compared to pharmacological therapy outcomes. Specifically, participants tended to require more favorable results and outcomes from surgical interventions to meet their minimum satisfaction criteria.

Summarizing the evidence for robotic-assisted bladder neck reconstruction: Systematic review of patency and incontinence outcomes.

Objective: Bladder neck contracture and vesicourethral anastomotic stenosis are difficult to manage endoscopically, and open repair is associated with high rates of incontinence. In recent years, there have been increasing reports of robotic-assisted bladder neck reconstruction in the literature. However, existing studies are small, heterogeneous case series. The objective of this study was to perform a systematic review of robotic-assisted bladder neck reconstruction to better evaluate patency and incontinence outcomes. Methods: We performed a systematic review of PubMed from first available date to May 2023 for all studies evaluating robotic-assisted reconstructive surgery of the bladder neck in adult men. Articles in non-English, author replies, editorials, pediatric-based studies, and reviews were excluded. Outcomes of interest were patency and incontinence rates, which were pooled when appropriate. Results: After identifying 158 articles on initial search, we included only ten studies that fit all aforementioned criteria for robotic-assisted bladder neck reconstruction. All were case series published from March 2018 to March 2022 ranging from six to 32 men, with the median follow-up of 5-23 months. A total of 119 patients were included in our analysis. A variety of etiologies and surgical techniques were described. Patency rates ranged from 50% to 100%, and pooled patency was 80% (95/119). De novo incontinence rates ranged from 0% to 33%, and pooled incontinence was 17% (8/47). Our findings were limited by small sample sizes, relatively short follow-ups, and heterogeneity between studies. Conclusion: Despite limitations, current available evidence suggests comparable patency outcomes and improved incontinence outcomes for robotic bladder neck reconstruction compared to open repair. Additional prospective studies with longer-term follow-ups are needed to confirm these findings.

Optimizing Surgical Outcomes in Congenital Syndactyly: Evaluation of Flap and Graft Techniques in Older Pediatric Patients.

Background Congenital syndactyly is a common congenital hand anomaly that impairs daily activities and impacts both functional and aesthetic outcomes. The fusion of adjacent fingers limits functionality and often requires surgical intervention to restore web spacing, maintain function, and improve appearance. This study evaluates surgical outcomes of congenital syndactyly treatment using flap and graft techniques, focusing on older patients. Methodology This study utilized retrospective data collected from patients aged 2 to 12 years diagnosed with congenital syndactyly. These patients underwent surgical separation procedures employing various flap techniques and full-thickness skin grafts. The chosen methods aimed to minimize scarring, secure optimal blood supply, and reduce postoperative complications. Postoperative assessments included web spacing, aesthetic appearance, and functional recovery. Results Patients generally experienced improved web spacing and proper alignment, with minimal contracture post-surgery. Flap and graft techniques effectively reduced visible scarring and provided favorable cosmetic results. Functional recovery was significant, allowing patients to resume age-appropriate tasks with minimal limitations, thereby restoring confidence in daily activities. Despite not undergoing early surgery, older patients still achieved marked improvements in web spacing, aesthetics, and overall function. Conclusions Surgical treatment of congenital syndactyly using flap and graft techniques significantly enhances both functional and aesthetic outcomes, even when the intervention is delayed beyond the recommended early age. Comprehensive planning and tailored approaches are crucial to achieving optimal web spacing, minimized scarring, and restored hand function. These measures ultimately improve the quality of life for patients, regardless of age at the time of surgery.

Preoperative risk-factors for secondary spontaneous pneumothorax surgery in Japan: a nationwide database study.

PURPOSE: We aimed to identify preoperative risk factors for secondary spontaneous pneumothorax surgery. METHODS: The National Clinical Database of Japan, with six annual datasets from 2014 to 2019, was used. All patients who underwent surgery for secondary spontaneous pneumothorax were included, excluding those < 15 years old and those with incomplete data. The effects of preoperative risk factors were analyzed for operative mortality (mortality during hospitalization or within 30 days, regardless of hospitalization status), 30-day mortality, and postoperative respiratory morbidities. RESULTS: Of the 18,309 patients enrolled in the study, operative mortality, 30-day mortality, and postoperative respiratory morbidities were observed in 654 (3.6%), 343 (1.9%), and 2258 (12.3%) patients, respectively. Increasing age, male sex, body mass index < 18.5 or > 30, performance status > 2, emergent surgery, interstitial pneumonia, and diabetes in preoperative co-morbidity, tumors, and other diseases in underlying lung disease were significant risk factors for operative mortality. Those for 30-day mortality included autoimmune disease instead of male sex and diabetes, while those for postoperative respiratory morbidities included lymphangiomyomatosis instead of a body mass index > 30. CONCLUSION: We identified many preoperative risk factors for operative mortality, 30-day mortality, and postoperative respiratory morbidities in secondary spontaneous pneumothorax surgery. These findings will assist in selecting appropriate surgical candidates.

Long-Term Outcomes of One-Stage Combined Posteroanterior Procedure and Laminoplasty-Alone for Multilevel Degenerative Cervical Myelopathy With Concomitant Anterior and Posterior Compression: A Propensity Score Matching Analysis of 8-year Follow-Up.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: This study aimed to investigate the long-term outcomes of laminoplasty-alone (LP) and combined procedure (CP), consisting of laminoplasty and single-level anterior cervical discectomy and fusion, in comparable patients who had multilevel degenerative cervical myelopathy (MDCM) with concomitant anterior and posterior compression (CAPC). METHODS: Consecutive MDCM patients with CAPC underwent LP or CP between 2012 and 2015 from a same surgical group were enrolled and followed up for a minimum of 8 years. Preoperative demographic, radiological, and clinical variables were collected. Propensity score matching (PSM) analysis was performed to match patients with comparable conditions. The outcomes were evaluated by postoperative Japanese Orthopedic Association (JOA) score improvement, JOA recovery rate (JOARR) and complications. RESULTS: A total of 230 patients were included, of whom 146 underwent LP and 84 underwent CP. After PSM, 84 pairs of comparable patients were matched. The matched groups presented fair comparability in preoperative conditions. The CP group had significantly prolonged surgery time and greater blood loss. At the final follow-up, the postoperative JOA scores of LP and CP groups were 14.51 ± 1.79 and 15.47 ± 1.81 (P < 0.001) and the JOARR were 42.5% ± 53.3% and 68.5% ± 35.4%, respectively (P < 0.001). Three (3.6%) patients in the LP group underwent reoperations because of recurrent symptoms (P = 0.081). CONCLUSION: Both LP and CP demonstrated considerable long-term neurological recovery in patients with CAPC. The CP showed a significantly higher JOA improvement and JOARR. The combined decompression might be a safe and effective alternative in treating MDCM with CAPC in experienced hands.

Evaluation of surgically treated primary spinal cord tumors in a single Indian institution: A case series study of 178 patients.

Introduction: Primary spinal cord tumors are rare tumors that are usually heterogeneous having variable histopathological subtypes. Rapidly, growing space-occupying lesions in the spinal canal cause severe loss of function. This study aimed to analyze all adult patients diagnosed with primary spinal cord tumors and to describe their location, symptoms, histopathological types, surgical outcome, complications, recurrence in a single institution, and prognostic factors. Materials and Methods: The study was a retrospective study of 178 patients with spinal tumor who underwent surgical intervention at the department of neurosurgery at a tertiary care institute from 2014 to 2021. Patient demographic characteristics, symptoms, radiological features, spinal level of tumor, spinal compartment, preoperative and postoperative McCormick grade, and complications were recorded, and a comparison of outcomes after surgical intervention was done. Results: In our study, 97 patients were males and the rest of the 81 patients were females. The mean age at the time of surgery was 43.5 years. The thoracic region of the spinal canal was the most involved with 67 (37.64%) cases, whereas intradural extramedullary was the most common (65.73%). Schwannoma was the most common histopathological subtype (46.06%). Total excision was achieved in 154 cases. A total of 37 patients were in Grades 4 and 5 of modified McCormick's grade preoperatively. However, postoperatively, there were only 17 patients in this group. Two patients with cervical intramedullary tumor expired in the postoperative period. Conclusion: Early surgical intervention with sound microneurosurgical skills gives good outcomes independent of the type and location of tumor. Better outcomes are seen in extradural tumors, early surgical intervention, tumors better amenable to total resection, and in patients with better preoperative neurological status.
