RESUMO
Background: Bladder cancer is a common urinary tract malignancy. Minimally invasive radical cystectomy has shown oncological outcomes comparable to the conventional open surgery and with advantages over the open procedure. However, outcomes of the two main minimally invasive procedures, robot-assisted and pure laparoscopic, have yet to be compared. This study aimed to compare in-hospital outcomes between these two techniques performed for patients with bladder cancer. Methods: This population-based, retrospective study included hospitalized patients aged ≥ 50 years with a primary diagnosis of bladder cancer who underwent robot-assisted or pure laparoscopic radical cystectomy. All patient data were extracted from the US National Inpatient Sample (NIS) database 2008-2018 and were analyzed retrospectively. Primary outcomes were in-hospital mortality, prolonged length of stay (LOS), and postoperative complications. Results: The data of 3284 inpatients (representing 16,288 US inpatients) were analyzed. After adjusting for confounders, multivariable analysis revealed that patients who underwent robot-assisted radical cystectomy had a significantly lower risk of in-hospital mortality (adjusted OR [aOR], 0.50, 95% CI: 0.28-0.90) and prolonged LOS (aOR, 0.63, 95% CI: 0.49-0.80) than those undergoing pure laparoscopic cystectomy. Patients who underwent robot-assisted radical cystectomy had a lower risk of postoperative complications (aOR, 0.69, 95% CI: 0.54-0.88), including bleeding (aOR, 0.73, 95% CI: 0.54-0.99), pneumonia (aOR, 0.49, 95% CI: 0.28-0.86), infection (aOR, 0.55, 95% CI: 0.36-0.85), wound complications (aOR, 0.33, 95% CI: 0.20-0.54), and sepsis (aOR, 0.49, 95% CI: 0.34-0.69) compared to those receiving pure laparoscopic radical cystectomy. Conclusions: Patients with bladder cancer, robot-assisted radical cystectomy is associated with a reduced risk of unfavorable short-term outcomes, including in-hospital mortality, prolonged LOS, and postoperative complications compared to pure laparoscopic radical cystectomy.
RESUMO
INTRODUCTION: The Chang Gung Forum has been dedicated to the care of craniofacial anomalies since 2000. This annual continuing medical education program focuses on orofacial cleft and surgery-first orthognathic surgery by providing up-to-date information and management guidelines. This study explored how the Chang Gung Forum has influenced medical perspectives, decisions, and practices in a multidisciplinary craniofacial team. METHODS: Between 2000 and 2022, 20 Chang Gung Forums have been held. A questionnaire was distributed among 170 attendees who had participated in the forum more than once. The questionnaire collected information on the participants' experiences and levels of satisfaction with the educational program and whether or how it had influenced their clinical practice. RESULTS: Valid responses from 86 attendees (response rate, 50.6%) who had participated more than once were collected and analyzed. The overall satisfaction rate of the Chang Gung Forum based on the respondents' most recent visits was 4.28 ± 0.63 out of 5. Of the respondents, 90.9% acknowledged changes in their clinical practice, with modifications in surgery plans and decisions being the most notable (48.5%). In addition, comprehension increased throughout years of attending the annual forum (P < 0.001). CONCLUSION: The Chang Gung Forum has contributed markedly to the community of congenital craniofacial anomalies. The program will continue providing updated information and influencing the clinical decision-making of health care professionals.

BACKGROUND: Computer-assisted surgical simulation (CASS) allows more precise orthognathic surgery. However, few studies have evaluated associations between CASS-designed bilateral sagittal split osteotomy (BSSO) and bone contact surface in class II mandibular asymmetry. This study aims to evaluate the effects of using computer-assisted simulation and design modification of sagittal split osteotomy (SSO) to improve bony contact in skeletal class II asymmetry. METHODS: This retrospective analysis reviewed 28 patients with class II asymmetry who underwent orthognathic surgery, including 15 with modified SSO (group CS) and 13 with conventional SSO (group C). Modified SSO was designed under CASS. Operative characteristics, postoperative outcomes, and complications were collected and compared between the two groups. RESULTS: Bony contact was found at the distal end of the proximal segment in all group CS patients, while bone gap was noted in all group C patients (p<0.05). Moreover, bone graft was used in four group C patients but was not used in all cases group CS patients (p<0.05). A trend toward lower operative time or perioperative bleeding was noted in group CS, but without statistical significance. After 1-year follow-up, inferior alveolar nerve disturbances were noted in two group CS patients and one group C patient. Palpable bone gap with uneven jaw line was noted in two group C patients one year after surgery and one patient received fat graft treatment. CONCLUSION: The simulation-based sagittal split osteotomy modification provides appropriate contact surface and eliminates the bone gap between proximal and distal segments in class II asymmetry.
RESUMO
BACKGROUND: Motorcycle injuries remain a significant cause of motor vehicle-related morbidity and mortality in Taiwan. Besides, the facial region is a commonly fractured site under motorcycle accidents. To date, there are no trauma mechanism-based studies of facial fractures. AIM AND OBJECTIVES: This study aims to determine the facial fracture patterns, the severity of head trauma, and associated injuries by different motorcycle-related trauma mechanisms enabling a greater understanding of its distribution and magnitude. METHODS: This is a retrospective descriptive analysis conducted over a 2-year period at Linkou Chang Gung Memorial Hospital. We focused on the population of maxillofacial injury caused by motorcycle accidents. We divided the patient cohort into 3 main trauma mechanisms: single-motorcycle collision (SM group), motorcycle-to-motorcycle collision (MM group), motorcycle-to-vehicle collision (MV group). Data, including demographics, age, fracture patterns of facial bones, and other associated injuries, were collected. RESULTS: A total of 881 cases were identified that involved facial fractures. Most patients were male (71%), young adult (mean age, 32.49 years), and the most common fracture region is the midfacial fracture (79.5%, 700 victims). Among the 3 groups, the MM group was less likely to sustain severe injuries by trauma score system, less head injury and mortality rate. The MV group and SM group have similar mortality rates but different fracture pattern tendencies. Lower facial fractures were more likely in the MV group, but midface fractures in the SM group. Associated injuries were higher in the MV group. CONCLUSIONS: Our study presents the different trends of fracture patterns and injury under 3 main mechanisms of motorcycle casualties. We document all these data in the hope of providing insights into trauma doctors dealing with motorcycle accidents.

BACKGROUND: The surgical management of hypertelorism is challenging for plastic surgeons, and limited long-term outcome data are available. The purpose of this long-term study was to report a single-surgeon experience with a staged reconstructive protocol for hypertelorism correction. METHODS: This retrospective study reviewed the records of patients with hypertelorism who were surgically managed by a single surgeon between 1978 and 2000. Bone (orbital box osteotomy and orthognathic surgery) and soft tissue (rhinoplasty and epicanthoplasty) surgeries were performed based on a patient-specific surgical protocol. Included patients were divided into a childhood group and an adolescence or adulthood group according to their age at orbital repositioning (≤12 and >12 years, respectively). Patients were invited for clinical interviews in February 2020 to evaluate whether requests for revision surgery had been made. The photogrammetric analysis-based hypertelorism index was calculated at preoperative and long-term postoperative times. Satisfaction with the long-term outcome was judged by both surgical professionals and laypeople. RESULTS: In total, 14 patients with hypertelorism of different etiologies were included, with no request for revision surgery during an average follow-up of 29 years. The preoperative hypertelorism index was higher than the long-term postoperative evaluation (all, P < 0.05) for both childhood and adolescence or adulthood groups. Intergroup comparison revealed no significant difference for the hypertelorism index and panel assessment-based satisfaction with long-term outcome analysis (all, P > 0.05). CONCLUSIONS: Considering the complexity and wide spectrum of clinical presentation of soft tissue and bone deformities in hypertelorism and current outcomes, the surgical approach to these patients should be staged and individualized for achievement of a balanced result between functional (orbital, occlusion, and psychosocial) and aesthetic parameters.

BACKGROUND: Every year, there are significant numbers of motorcycle accident casualties in Taiwan. These accidents are the leading cause of maxillofacial trauma. Age should be an important factor of maxillofacial fracture patterns yet there is limited literature on the topic. Therefore, this study aims to evaluate the correlation of age with maxillofacial fracture in motorcycle accidents. METHODS: This is a retrospective descriptive analysis conducted over 2-year period at Linkou Chang Gung Memorial Hospital. We focused on the population of maxillofacial injury caused by motorcycle accidents. Data, including demographics, age, fracture patterns of facial bones, and other associated injuries, were collected. RESULTS: Among 881 admissions, there were 179 patients in the minor group, 644 patients in the adult group, and 58 patients in the geriatric group. With patterns of maxillofacial fracture, midface fracture was the most common type. The minor group had higher incidence of mandibular fracture. The geriatric group sustained more midface fracture. Associated injuries, such as severe head injuries and c-spine injury, were more likely to occur with the old age victims. The overall mortality rate was 3.1%. CONCLUSIONS: Our study presents the different trends of fracture patterns in different age groups, which is associated with different types of treatment required. We summarized all these data in the hope of providing further assistance to trauma doctor dealing with motorcycle accidents.

Aggressive angiomyxoma is a very rare benign tumor for male population with fewer than 50 cases reported since the description of this tumor. Most documented cases of aggressive angiomyxomas were found in genital, perineal, and pelvic regions in women of child bearing age. We report a case of a massive (> 20 cm) aggressive angiomyxomas in a man who presented with perineal swellings. Macroscopically the mass was highly vascular and lobulated with high similarity to plexiform neurofibroma. Microscopic examination revealed a hypocellular tumor comprising bland oval and spindle-shaped cells along with vessels of varying calibre. The accompanying stroma was myxocollagenous. Immunohistochemical staining showed CD34 and focal estrogen receptors positivity and negative staining for S100, actin, desmin, and progesterone receptors. The histologic and immunohistochemical features favored the diagnosis of aggressive angiomyxoma. Despite the rarity of such tumor in the male population, aggressive angiomyxoma should be considered in the differential diagnosis when encountering chronic para-perineal lesions.
