BACKGROUND: Intrathoracic paragangliomas are typically found within the intricate posterior mediastinal region adjacent to the vertebrae, often presenting with substantial volume. Surgical excision of such tumors presents formidable challenges and is conventionally performed via open surgical procedures.
METHODS: In this report, we present the case of a 53-year-old female patient who presented with the discovery of a left intrathoracic mass during a routine physical examination approximately 1 month prior. She complained of chest tightness and chest pain.
METHODS: She complained of chest tightness and chest pain. Magnetic resonance imaging of the chest and brachial plexus revealed a mass adjacent to the left upper lung hilum, measuring approximately 78 × 63 × 72 mm. The initial suspicion leaned towards a benign lesion. Notably, there was slight compression of the left first thoracic nerve root and mild compression of the middle and lower trunks of the left brachial plexus. Based on the morphological features of the tumor and imaging findings, we suspected its benign nature.
METHODS: We opted for robot-assisted thoracic surgery to resect the mediastinal tumor.
RESULTS: Subsequent postoperative pathology confirmed the diagnosis as a paraganglioma. The patient did not experience any notable complications post-surgery, and a 6-month follow-up revealed no signs of recurrence.
CONCLUSIONS: The successful application of the robot-assisted thoracic surgery surgical technique underscores its efficacy in minimally invasive resection of sizable intrathoracic tumors situated in the posterior mediastinum.

OBJECTIVE: This study aims to prospectively analyze the effects of anticholinergic therapy using imidafenacin on detrusor overactivity occurring after robot-assisted radical prostatectomy (RARP).
METHODS: Patients were followed-up at outpatient visits 2-4 weeks post-surgery (visit 2) to confirm the presence of urinary incontinence. Those confirmed with urinary incontinence were randomly assigned in a 1:1 ratio to the anticholinergic medication group (imidafenacin 0.1 mg twice daily) or the control group. Patients were followed-up at 1, 3, and 6 months post-surgery for observational assessments, including the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS).
RESULTS: A total of 49 patients (25 in the treatment group and 24 in the control group) were randomized for the study. There were no differences observed between the groups in terms of age, comorbidities, prostate size, or pathological staging. According to the IPSS questionnaire results, there was no statistically significant difference between the medication and control groups (p=0.161). However, when comparing storage and voiding symptoms separately, there was a statistically significant improvement in storage symptom scores (p=0.012). OABSS also revealed statistically significant improvement in symptoms from 3 months post-surgery (p=0.005), which persisted until 6 months post-surgery (IPSS storage: p=0.023, OABSS: p=0.013).
CONCLUSIONS: In the case of urinary incontinence that occurs after RARP, even if the function of the intrinsic sphincter is sufficiently preserved, if urinary incontinence persists due to changes in the bladder, pharmacological therapy using imidafenacin can be beneficial in managing urinary incontinence.

Robotic surgery has been widely used in surgical gastric cancer treatments, including proximal gastrectomy. Single-port robotic system is gaining more popularity in robotic surgery, but there has been no report on its application in robotic proximal gastrectomy with right-sided overlap and single-flap valvuloplasty (RPG-ROSF). Here, we report an RPG-ROSF using a novel single-port robotic system in a 51-year-old male patient with an early-stage gastroesophageal cancer detected by gastroscopy. It took 90 min for robotic setup, 143 min for dissection, and 161 min for digestive tract reconstruction. There was no complication during and after the surgery. The patient was discharged in 8 days postsurgery. The pathological staging of the adenocarcinoma was pT1aN0M0. This preliminary study demonstrated the feasibility and safety of a novel single-port robot in RPG-ROSF.

BACKGROUND: total hip arthroplasty (THA) is one of the most performed surgeries worldwide, with high satisfaction rates. The orientation of the acetabular component has a direct impact on the risk of dislocation, recently with the support of robotic surgery the margin of error in implant placement has decreased; however, the conventional technique even without fluoroscopic support continues to have satisfactory results within the safety zone.
METHODS: retrospective, cross-sectional, descriptive case series of patients treated with THA at Hospital General Xoco between 2022 and 2024. Degrees of anteversion and inclination were measured with Widmer\'s method on postoperative radiographs.
RESULTS: the radiographs of 113 patients were studied, 80 female and 33 male, with a mean age of 63.2 ± 13.01 years (95% CI: 60.6-65.4), a mean inclination of 42.2° ± 8.1° (95% CI: 40.7-43.2) and anteversion of 14.3° ± 8.5° (95% CI: 12.5-15.4); 76% of the population was within Lewinnek safe zone; by etiology: osteoarthrosis 74%, sequelae of dysplasia 68% and intracapsular fracture 82%; difference between the values of the affected side: left 65%, right 83%, of 3.9° and 4.7°/6.4o and 9° in relation to the overall values of the population.
CONCLUSIONS: in our population undergoing THA, without the use of robotic technique or support of imaging studies, anteversion and inclination figures were recorded within the Lewinnek safety parameters with a conventional method.
UNASSIGNED: la artroplastía total de cadera (ATC) es una de las cirugías más realizadas a nivel mundial, con altos porcentajes de satisfacción. La orientación del componente acetabular tiene impacto directo en el riesgo de luxación; recientemente, con el apoyo de la cirugía robótica, el margen de error en la colocación de los implantes ha disminuido; sin embargo, la técnica convencional, incluso sin apoyo fluoroscópico, continúa teniendo resultados satisfactorios dentro de la zona de seguridad.
UNASSIGNED: serie de casos retrospectiva, transversal y descriptiva, de pacientes tratados con ATC en Hospital General Xoco entre 2022 y 2024. Se midieron los grados de anteversión e inclinación con el método de Widmer en las radiografías postoperatorias.
RESULTS: se estudiaron las radiografías de 113 pacientes, 80 mujeres y 33 hombres, con edad media de 63.2 ± 13.01 años (IC95%: 60.6-65.4), se obtuvo una inclinación media de 42.2° ± 8.1° (IC95%: 40.7-43.2) y anteversión de 14.3° ± 8.5° (IC95% 12.5-15.4); 76% de la población se encontraba dentro de la zona segura de Lewinnek; por etiología: osteoartrosis 74%, secuelas de displasia 68% y fractura intracapsular 82%; diferencia entre los valores del lado afectado: izquierdo 65%, derecho 83%, de 3.9° y 4.7°/6.4° y 9° en relación con los valores globales de la población.
UNASSIGNED: en nuestra población sometida a ATC, sin uso de técnica robótica o apoyo de estudios de imagen, se registraron cifras de anteversión e inclinación dentro de los parámetros de seguridad de Lewinnek con un método convencional.

METHODS: A healthy 15-year-old male competitive hockey player presented with acute-on-chronic lower back pain was found to have a bilateral pars defect. After conservative treatment, subsequent computed tomography imaging demonstrated partial healing of the right-sided facet fracture but persistent left-sided pars fracture. A novel technique was performed, using robotic navigation to assist in laminar screw placement and to determine the optimal trajectory for subsequent microscopic surgery and bone grafting.
CONCLUSIONS: Robotic navigation can be safely used to not only guide precise laminar screw placement for fixation and direct repair but also to provide guidance for microscopic tubular bone grafting of the pars defect.

Background: Renal angiomyolipoma (AML) without local invasion is generally considered benign. However, it may extend to the renal sinus, even the renal vein, or the inferior vena cava (IVC). In patients with non-tuberous sclerosis complex, coexistence of renal cell carcinoma (RCC) and renal AML is uncommon. Case presentation: A 72-year-old woman was incidentally found to have a solitary right renal mass with an IVC thrombus extending into the right atrium during a routine health checkup. Robot-assisted laparoscopic radical nephrectomy and thrombectomy were successfully performed through adequate preoperative examination and preparation. Two tumor lesions were found and pathologically confirmed as renal AML and RCC, and the tumor thrombus was derived from the renal AML. During the one-year follow-up period, no signs of recurrence or metastatic disease were observed. Conclusions: Renal AML with a tumor thrombus in the IVC and right atrium accompanied by RCC may occur, although rarely. In clinical practice, if preoperative manifestations differ from those of common diseases, rare diseases must be considered to avoid missed diagnoses. In addition, adequate examination and multidisciplinary discussions before making a diagnosis are necessary. For a level 4 tumor thrombus with no infringement of the venous wall, adoption of robot-assisted minimally invasive surgery, without extracorporeal circulation technology, is feasible.

OBJECTIVE: Robot-assisted sacrocolpopexy (RASC) is increasingly common due to the increased uptake of surgical robot systems. The aim of this retrospective study was to assess the perioperative outcomes of the first patient cohort to undergo RASC using a brand-new surgical robot system, the hinotori surgical system (robot-assisted sacrocolpopexy with hinotori surgical system [h-RASC]). This study also aimed to compare the outcomes of this group with those of the group of patients who had undergone RASC with the da Vinci surgical system (d-RASC).
METHODS: This study included 15 patients per group. Operative times, blood loss, complications, overactive bladder symptom score (OABSS; subjective measure), and urodynamic outcomes (objective measure) were compared between the groups.
RESULTS: All cases were completed without serious problems during RASC procedure. Perioperative outcomes were similar between the groups except for longer operation time (min) (h-RASC 266 vs. d-RASC 229; p < .01) and console time (min) (178 vs. 159; p = .02) in the h-RASC group than in the d-RASC. De novo stress urinary incontinence (SUI) and pelvic organ prolapse (POP) recurrence were comparable. LUTS improved in the postoperative OABSS total score (preoperative 6 vs. postoperative 3; p < .01) in the h-RASC group. However, OABSS assessment (h-RASC -3 vs. d-RASC -4; p = .38) was similar between the two groups. Urodynamic studies showed similar outcomes in the median Qmax (maximum flow rate) values in both groups.
CONCLUSIONS: This is the first report focusing on RASC using the hinotori surgical system. RASC using the hinotori surgical system could provide favorable perioperative outcomes as comparable with those of the existing da Vinci system.

BACKGROUND: Adrenal hemangiomas are extremely rare benign tumors that often need to be distinguished from malignancies. Adrenal tumors >4 cm in size are treated surgically because the possibility of malignancy cannot be ruled out. Traditionally, open surgery has been the mainstay of treatment; however, in recent years, robot-assisted surgery has been increasingly used for tumors of larger size and suspected malignancy. Here, we report a case of robot-assisted adrenalectomy for an 11 cm adrenal hemangioma.
METHODS: A 62-year-old male with lateral abdominal pain was referred to our hospital for further examination and treatment. His medical history was significant for hypertension, diabetes, and dyslipidemia. Computed tomography revealed an 11 cm left adrenal tumor, and all endocrinological screening tests were negative. Because the possibility of malignancy could not be ruled out, a robot-assisted adrenalectomy was performed. The operation time was 129 min, and the estimated blood loss was 7 ml. Pathological findings revealed an adrenal hemangioma. The postoperative course was uneventful, and patient\'s condition subsequently improved postoperatively.
CONCLUSIONS: Robot-assisted adrenalectomy was performed for a giant adrenal hemangioma without any complications. Robotic surgery is useful for resecting adrenal hemangiomas even exceeding 11 cm in diameter.

OBJECTIVE: This study aims to evaluate the role of intraoperative control of the watertightness of vesicourethral anastomosis extravasation control (VUAEC) in predicting vesicourethral anastomosis (VUA) healing and early postoperative outcomes in patients undergoing robot-assisted radical prostatectomy (RARP).
METHODS: 100 patients who underwent RARP between October 2020 and May 2023 were consecutively included in the study. Preoperatively, the patients were randomized to undergo VUAEC (Group-A) or not (Group-B). Patients in Group-A were evaluated in 2 subgroups: those with no extravasation observed during VUAEC (Group-A1; n = 31 (62%)) and those with extravasation (Group-A2; n = 19 (38%)). On the 8th post-operative day, a gravity cystogram (GC) was performed on all patients to assess VUA healing.
RESULTS: There was no statistically significant difference between the groups in terms of clinical features, drain removal time, length of hospital stay, extravasation on GC, catheter removal time and postoperative complications (p > 0.05, for each). There was also no statistically significant difference between the subgroups in terms of drain removal time, length of hospital stays, catheter removal time (p > 0.05, for each). In Group-A2, urinary extravasation on GC was found in a greater percentage, but the difference remained statistically insignificant (p = 0.082).
CONCLUSIONS: Performing intraoperative VUAEC did not have a significant role in the prediction of VUA healing and early postoperative outcomes in patients undergoing RARP. The current study did not identify a substantial clinical benefit of routine intraoperative VUAEC.
