The Clinical Impact of the Introduction of a Robot-Assisted Program in a Specialized Hernia Center: A Propensity Score Matched Cohort Study on Short-Term Outcomes.

The role of robot-assisted approach in hernia surgery remains controversial due to high procedural costs and the proposed equal outcomes compared with open surgery. In this study, we report the 30-day results of the introduction of robot-assisted approach in a specialized regional ventral hernia repair center. This was a retrospective single-center cohort study including patients undergoing either robot-assisted or open ventral hernia repair from 2017 to 2022. Patients undergoing either approach were matched by propensity scores in a 1:2 ratio on the variables age, type of hernia (primary/incisional), and horizontal fascial defect size to reduce bias risk. Multivariable logistic regression on outcomes length of stay, reoperation, and readmission was performed. A total of 109 patients undergoing robot-assisted repair were compared to 229 undergoing open repair. Overall, 61.2% were patients hadincisional hernia. Mean hernia defect size was 4.9×6.5cm (horizontal×vertical). The mean length of stay was shorter after robot-assisted repair (0.1 vs. 1.9days, p<0.001) as was the incidence of readmission (3.7% vs. 17.0%, p<0.001). The incidence of reoperation was tangentially significantly lower after robot-assisted repair (0.9% vs. 6.6%, p=0.045); however, the estimate was significant after adjusting for confounders (OR 0.11, CI 0.01-0.89, p=0.038). Length of stay and readmission rates were significantly decreased after the introduction of a robot-assisted approach for ventral hernia repair.

The Therapeutic Potential of Different Surgical Approaches in the Management of Cardiac Myxoma: A Systematic Review.

Background: Cardiac myxomas are benign tumors of the heart. They occur mostly in the left atrium. The preferred treatment is surgical resection, which can be performed via conventional median sternotomy, minimally invasive, or robotic-assisted approaches. This study aimed to evaluate the outcomes, advantages, and limitations of these surgical methods, with a focus on their safety, efficacy, and impact on patient recovery. Methods: This systemic review was conducted according to PRISMA guidelines. The chosen databases were systematically searched using the keywords "cardiac myxoma", "resection", "approach", "minimally invasive", and "robotic surgery". The comparison between the surgical strategies was based on thirteen articles, which met the inclusion criteria. Results: Median sternotomy remains the standard technique, providing excellent surgical access but is associated with longer hospital stays, higher blood loss, and increased risk of complications such as stroke. Minimally invasive approaches demonstrated comparable safety with shorter ICU stays, reduced blood loss, and lower postoperative pain but presented challenges, including limited exposure and longer procedure times. Robotic-assisted surgery showed potential as a safe alternative but was limited by high costs and technical demands. However, the data on minimally invasive and robotic methods are limited due to the rarity of cardiac myxomas. Conclusions: The choice of surgical technique should be individualised by considering the tumour size, location, patient condition, and surgeon expertise. Routine postoperative echocardiographic monitoring is essential to detect residual or recurrent tumours. Further studies are needed to validate the long-term efficacy of minimally invasive and robotic approaches.

Associations between (pharmaco-)genetic markers and postoperative pain after inguinal hernia repair – a prospective study protocol

BackgroundPostoperative pain is a common complication following surgery, with severity and duration varying between patients. Chronic postoperative pain after inguinal hernia surgery has an incidence rate of approximately 10%. Risk factors for acute and chronic pain following hernia surgery include age, sex, psychosocial factors, and demographic background. Additionally, genetic polymorphisms in enzymes involved in pain mechanisms, as well as the metabolism of analgesics might influence pain perception, pain development, and response to pain medications. Key enzymes include the catechol-o-methyltransferase (COMT), the µ-opioid receptor 1 (OPRM1), and the cytochrome P450 2D6 (CYP2D6).CYP2D6 plays a crucial role in metabolizing analgesics such as tramadol, codeine, and oxycodone. It is also suspected to be involved in the synthesis of catecholamines and endogenous morphines suggesting a potential role in pathophysiology of pain. We hypothesize that the CYP2D6 activity influences the development of postoperative pain after hernia surgery.MethodsThis study is a prospective, observational, multicenter association study investigating adult patients scheduled for inguinal hernia surgery using a robotic-assisted (rTAPP) approach. Patients are enrolled during the preoperative surgical consultation. A buccal swab is collected for genetic testing at this time. Pain at the site of the hernia is assessed using the validated EuraHSQoL score preoperatively and at 2, 4, and 6 weeks postoperatively. Additionally, information on co-medication and details of the surgery will be collected. The planned number of participants is 350 patients. The primary objective is to analyze the association between different genotype-predicted CYP2D6 phenotypes and patient-reported pain intensity 6 weeks after surgery. Secondary objectives include the association between further genetic variants, such as the COMT rs4680 and OPRM1 rs1799971 genotype, and pain severity. Additionally, the potential of pharmacogenetic panel testing to optimize analgesic therapy in hernia surgery patients will be explored.DiscussionThe findings of this study are expected to provide valuable insights into identifying patients at higher risk for postoperative pain before surgery. This knowledge could pave the way for tailored interventions during and after surgery for these specific patients.Trial registrationDeutsches Register Klinischer Studien https://www.drks.de/DRKS00034796 Registered on August 07, 2024.

Preserving Cervical Mobility: A Novel Robot-Assisted Approach for Atlas Fracture Fixation

Preserving Cervical Mobility: A Novel Robot-Assisted Approach for Atlas Fracture Fixation

Current surgical treatment of uterine isthmocele: an update of existing literature.

The prevalence of uterine isthmocele, also known as a uterine niche, has risen in parallel with increasing cesarean section (CS) rates, affecting approximately 60% of women depending on their history of cesarean deliveries. This condition, now categorized as cesarean scar disorder (CSD) by the "Delphi consensus," is characterized by one primary or two secondary symptoms. Diagnosis can be made through transvaginal ultrasound, sonohysterography, hysteroscopy, or magnetic resonance imaging (MRI). Management of isthmocele may involve pharmacological or surgical interventions. This review aims to provide a thorough analysis of the surgical management options, focusing on postoperative symptom relief, intraoperative and postoperative complications, length of hospital stay, and impact on secondary infertility. PubMed was comprehensively searched for observational studies from inception to 07.08.2024. Surgical treatments include hysteroscopic resection, laparoscopic procedures, and vaginal approaches, all of which offer comparable symptom relief. However, the vaginal approach is associated with a longer hospital stay. The robotic-assisted approach shows promising results but lacks extensive data. Among surgical options, hysteroscopic treatment has the fewest complications but is generally avoided when residual myometrial thickness (RMT) is less than 3mm. While many CSDs remain asymptomatic, and some women with uterine isthmocele may not wish to conceive, symptomatic patients or those desiring to conceive may benefit from surgical intervention. The choice of procedure should be based on individual patient characteristics, particularly RMT, to define the most appropriate surgical approach.

Robotic salvage radical hysterectomy for locally recurrent cervical cancer: A comparison with open surgery in a single-surgeon series.

To compare the surgical and oncologic outcomes between patients with locally recurrent cervical cancer undergoing robotic-assisted salvage radical hysterectomy (RH) and those undergoing conventional open salvage RH, performed by a single surgeon. This retrospective comparative observational study utilized data obtained from consecutive patients with locally recurrent cervical cancer, developed after definitive radiotherapy. These patients either underwent robot-assisted RH (robotic group) or conventional open RH (open group). Clinicopathological characteristics, surgical outcomes, and oncological outcomes were compared between the two groups. The operative time was slightly longer in the robotic group; however, this difference was not statistically significant. Estimated blood loss was significantly lower in the robotic group (median; 0 mL [robotic group] vs. 700 mL [open group]: p < 0.01). The incidence of intraoperative and early and late complications did not statistically differ between the two groups. The mean follow-up was 29.0 and 17.1 months in the open and robotic groups, respectively. Disease recurrence rates were similar between the two groups (40% [robotic group] vs. 44.4% [open group]). Kaplan-Meier survival analysis for progression-free survival and overall survival did not show statistically significant differences between the two groups. Robot-assisted salvage RH in women with locally recurrent cervical cancer showed perioperative and oncological outcomes comparable to those of the open procedure. Although our results suggest that the robot-assisted approach is as good as or better than the open approach, further investigation is required to establish a more robust conclusion.

Surgical and oncological outcomes of salvage radical prostatectomy after focal therapies: a matched-pair analysis.

To determine the surgical and oncologic outcomes of salvage radical prostatectomy (sRP) after FT failure. Patients who consecutively underwent primary RP or sRP after FT failure between 2008 and 2022 were retrospectively selected. Primary or sRP were performed with either a robot-assisted or open approach. All surgeries were performed by surgeons with experience of ≥ 500 cases. Biochemical recurrence-free survival (BFS), intra- and postoperative surgical and functional outcomes were assessed. To evaluate the impact of surgical setting, propensity score (PS) matching was performed. 80 patients received sRP. Outcomes were analyzed using PS-matched cohorts (203 RPs vs. 68 sRPs). After a median follow-up of 25.4 months, sRP and RP had equal BFS (24mo-BFS: 72.4% vs. 76.0% (p = 0.8)). No statistically significant differences were found between sRP and RP in terms of median operative time (OT) (171min vs. 168min), estimated blood loss (EBL) (500ml vs. 500ml), length of hospital stay (LOS) (7 days vs. 7 days) and time to catheter removal (11 days vs. 11 days) and 1-year continence rates (all standardized mean differences ≤ 0.1). The main limitation is the retrospective study design. In the hands of experienced surgeons, sRP after FT offered comparable surgical and oncologic outcomes as RP in a primary setting.

Robot-assisted stylomastoid foramen puncture and radiofrequency ablation for hemifacial spasm treatment: clinical outcomes and technique assessment.

Stylomastoid foramen (SMF) puncture with radiofrequency ablation (RFA) is a minimally invasive therapy for hemifacial spasm (HFS) with notable therapeutic outcomes. Conventionally, this procedure is performed under CT guidance. The present study highlights the authors' preliminary clinical experience with robot-assisted SMF puncture in 7 patients with HFS using a neurosurgical robot. Patients were secured in a skull clamp, and their heads were linked to the Sinovation neurosurgical robot's linkage arms for precise positioning. Bone fiducial registration was conducted using the robotic pointer. Under robotic guidance, a puncture needle was positioned at the skin entry point and then advanced to the target with a surgical blade incision. On target attainment, an RFA electrode was positioned, and the ablation was performed while monitoring facial nerve function. Preoperative and postoperative spasm grading, surgical metrics, and adverse events were meticulously documented. The puncture trajectories averaged 49.5 mm in length, and the overall operation duration was 27.3 minutes. Guided by the robotic arm, all puncture attempts were successfully achieved without any obstructions, and SMF puncture was completed in a single attempt. Following RFA, immediate spasm relief was achieved, with all patients attaining Cohen spasm grade 0. Over a mean follow-up period of 12 months (range 6-15 months), no recurrence of spasms was reported. Facial paralysis was observed in 85.7% of patients, with 6 cases classified as House-Brackmann (HB) grade II and 1 case as grade III. At the final follow-up, 1 patient remained at HB grade II, while the remaining patients improved to grade I. No other lasting or severe complications were recorded. SMF puncture and RFA emerge as a potent and minimally invasive treatment option for HFS. The robot-assisted approach, despite necessitating additional time for head fixation and registration, notably reduces the overall puncture time, puncture attempts, and radiation exposure, thereby enhancing the puncture success rate.

The Association Between Sociodemographic Factors and Delays to Minimally Invasive Surgery for Stage IA-IIIA Non-small Cell Lung Cancer.

Surgical resection is the gold standard treatment for early-stage non-small cell lung cancer (NSCLC). Prior studies have found that delayed treatment carries risk of disease progression. However, factors that predict delay to surgery are relatively understudied. The aim of this study was to identify characteristics associated with time to surgery. The National Cancer Database was queried for patients with stage IA-IIIA NSCLC who underwent upfront resection from 2017 to 2021. The primary outcome was time to surgery examined as a continuous and categorical variable in which patients were divided into timely (≤6 weeks) and delayed (>6 weeks) surgery cohorts. Across 75,047 patients, the median time to surgery was 41 days (interquartile range, 19-64 days). Of these patients, 39,685 (52.9%) were in the timely cohort and 35,362 (47.1%) were in the delayed cohort. After risk adjustment, significant predictors of increased odds of delayed surgery included African-American race (odds ratio [OR], 1.46; 95% CI, 1.34-1.59), lack of insurance (OR, 1.70; 95% CI, 1.33-2.17), lower educational status (OR, 1.15; 95% CI, 1.04-1.25]), lower household income (OR, 1.40; 95% CI,1.28-1.54), and use of a robotic-assisted approach (OR, 1.21; 95% CI, 1.15-1.27). Patients whose surgery was delayed had significantly increased risk-adjusted odds of upstaging (OR, 1.15; 95% CI, 1.04-1.28), 30-day mortality (OR, 1.24; 95% CI, 1.02-1.52), and 90-day mortality (OR, 1.25; 95% CI, 1.08-1.45]). After risk adjustment for oncologic characteristics, sociodemographic factors are associated with delay to definitive surgery in NSCLC and subsequent increased odds of mortality and pathologic upstaging. Future work should explore strategies to improve availability and accessibility of timely treatment for these patient populations to ameliorate disparities in care for NSCLC.

The safety, accuracy, and feasibility of robotic assistance in neuro-oncological surgery.

Over the past 3 decades, robotic technology has advanced significantly across surgical fields, driven by improvements in versatility, stability, skill, and tactile properties. Neurosurgery has led the way in integrating robotics to improve the accuracy and safety of procedures that require high precision. This study aimed to present one of the largest series in the literature and investigate the feasibility and effectiveness of robotic assistance in neuro-oncological surgery. The authors performed a retrospective review of the medical records of patients who underwent stereotactic biopsy only and biopsy and laser interstitial thermal therapy (LITT) using the Robotic Surgical Assistant (ROSA) system. The ROSA system was used for trajectory planning as well as the precise alignment and insertion of the needle and/or laser catheter. All procedures were performed by a single neurosurgeon. Electronic medical records were reviewed for patient demographics, preoperative clinical deficits, diagnosis, preoperative and postoperative MR images, lesion characteristics including location and volume, postoperative complications, and deficits. A total of 348 patients were identified. The mean age at surgery was 61.4 years, with 171 (49.1%) females. The most common presentations were GBM (40.5%, n = 141), metastasis (16.4%, n = 57), and radiation necrosis (9.8%, n = 34). A total of 189 (54%) patients underwent stereotactic biopsy only, and 159 (46%) underwent biopsy and LITT. The diagnostic yield of the cases was 98.6%, with only 5 cases having inconclusive pathology. Two (0.6%) patients experienced postoperative complications that resolved during follow-up. Ten (2.9%) patients developed asymptomatic subcentimeter hematomas following the procedure that did not require further intervention. No long-term consequences or permanent deficits occurred in any case within a median follow-up duration of 4.4 months (IQR 1-11.2 months). These results indicate that a robot-assisted approach for stereotactic biopsies and LITT is associated with a comparable diagnostic yield and safety profile for frameless and frame-based techniques. Its precision, user-friendly interface, and adaptability contribute to its suitability for such procedures. Future research, especially in long-term results and cost-effectiveness, will be crucial in fully understanding the utility and potential of this technology for broader applications in the field.

Robot-assisted phenotyping of a Corynebacterium strain library towards valorization of next-generation feedstocks

The identification of microorganisms capable of efficiently using the different carbon sources (sugars, sugar acids, and sugar alcohols) and tolerating inhibitory by-products in hydrolysates is a challenge for the development of efficient bioproduction from lignocellulosic biomass (LCB). In this study, a robot-assisted screening approach was developed to characterize a collection of 32 Actinomycetes type strains, mainly belonging to the genus Corynebacterium. Using robot-assisted replica plating, the use of 12 different carbon-sources as well as the level of tolerance against prominent inhibitors derived from LCB was assessed. Based on a combined analysis of substrate utilization profiles and inhibitor tolerance five strains were chosen for further characterization in a miniaturised cultivation system using ultrafiltrated spent sulfite liquor (SSL) as the sole substrate. Noteworthy, in these experiments Corynebacterium sp. ATCC 14747 showed fast growth and biomass accumulation even in presence of high SSL concentrations.

Patient, facility, and surgical factors associated with significant delays to esophagectomy and subsequent poor outcomes: An analysis of 16,486 cases

ObjectiveDelays to definitive surgery in esophageal cancer may be associated with disease progression and worsened survival. The objective of this study was to perform a national assessment for predictors of delay to esophagectomy and to assess for their impact on oncologic and survival outcomes. MethodsThe National Cancer Database, 2010 to 2020, was queried for patients with locally advanced esophageal adenocarcinoma (stage I-III). Patients were divided into up-front and postneoadjuvant chemoradiation cohorts. The primary outcome was time to surgery. Time to surgery was examined as a continuous and categorical variable, where patients were divided into timely and delayed cohorts (96 days for up-front cohort; 56 days for postneoadjuvant chemoradiation cohort). ResultsOf 16,486 patients, 4066 (24.7%) underwent up-front surgery and 12,420 (75.3%) underwent postneoadjuvant chemoradiation surgery. In the up-front surgery group, median [interquartile range] time to surgery was 61 [40-96] days. Risk-adjusted predictors of delay included lack of insurance, lowest quartile of education, biopsy-based staging or surgical staging, and robotic-assisted approach. In the postneoadjuvant chemoradiation, cohort time to surgery was 55 [44-70] days. Risk-adjusted predictors of delay included Hispanic ethnicity, Medicaid or other government-based insurance, lowest quartile of educational status, and robotic approach. In the up-front surgery group, patients who received delayed surgery had increased odds of pathologic upstaging (1.31, 95% CI, 1.06-1.61). In the postneoadjuvant chemoradiation group, patients with surgical delay had increased odds of 90-day mortality (1.27, 95% CI, 1.06-1.51). ConclusionsAfter risk adjustment for patient, oncologic, facility, and surgical characteristics, there were several predictors of increased time to esophagectomy associated with consequences of upstaging and survival.

Robotic assisted excision of a mesenteric cyst of Müllerian origin in a 29-year-old woman

Mesenteric cysts are rare, benign tumors of uncertain etiology that require management. The Müllerian subtype of one of the rarer types of mesenteric cysts. Diagnosis of a mesenteric cyst typically involves nonspecific symptoms or an asymptomatic presentation. Treatment involves resection to prevent life-threatening complications. Resection through laparotomy surgery is the most common approach. The laparoscopic approach is gaining traction. We present a case in which a large mesenteric cyst was resected using a robotic assisted laparoscopic approach.

A case of late presentation of recurrent primary choledocholithiasis 30 years post-cholecystectomy: Presentation and management

Acute cholangitis typically occurs secondary to biliary obstruction and bile stasis. While the most common cause is secondary choledocholithiasis (i.e., stones form in the gallbladder and are expelled into the common bile duct), there is little information on primary choledocholithiasis as the principal source of this obstruction. Furthermore, it is particularly rare to see symptomatic choledocholithiasis years to decades later in patients who previously underwent cholecystectomy. We report a complex case of a 75-year-old woman who presented to the emergency department with a 3 to 4-day history of abdominal pain, nausea, generalized weakness, fever, and shortness of breath. She had septic cholangitis due to primary choledocholithiasis 30 years post-cholecystectomy and numerous other comorbidities that increased the complexity of her case. Endoscopic retrograde cholangiopancreatography (ERCP) was attempted to remove the stone but was unsuccessful due to duodenal diverticula. Eventually, this patient underwent common bile duct exploration using a robot-assisted approach. A 2 cm stone at the distal common bile duct was removed, and her clinical status dramatically improved. The efficiency and increased fine control of a robot-assisted approach introduces our idea that this approach should be an alternative management option for minimally invasive common bile duct exploration in patients who have high-risk comorbidities and failed ERCP. Keywords: Acute cholangitis, primary choledocholithiasis, recurrent choledocholithiasis, post-cholecystectomy, robotic-assisted common bile duct exploration

How i do it: Robot-assisted transcerebellar stereotactic approach for brainstem lesion.

Stereotactic approaches to diffuse intrinsic pontine gliomas (DIPGs) remain essential due to advances in molecular biology and management, necessitating tissue sampling. Here we present an effective technique with a biopsy by robot-assisted transcerebellar approach. Our procedure was performed using the ROSA robotic system and the OARM CT scan, which provided stereotactic conditions for this transcerebellar approach to brainstem lesions. The robot-assisted transcerebellar stereotactic approach remains essential to provide complications for biopsy of brainstem lesions.

Relationship between Preoperative Red Cell Distribution Width and Prolonged Postoperative Use of Catecholamines in Minimally Invasive Mitral Valve Surgery Patients: A Retrospective Cohort Study.

Background/Objectives: Elevated RDW has emerged in cardiac surgery as a potential means of preoperative risk stratification with the capacity to predict short- and long-term postoperative mortality, acute kidney injury, and postoperative atrial fibrillation. The question as to whether perioperative hemodynamic instability may be predicted by such a marker remains a topic of ongoing debate. The aim of this study was to explore the relationship between preoperative RDW and prolonged postoperative catecholamine use in minimally invasive mitral valve surgery. Methods: We performed a retrospective monocentric cohort study in an academic hospital; we enrolled patients who had undergone minimally invasive mitral valve surgery (including both robot-assisted and non-robot-assisted procedures) between January 2019 and December 2022. We considered the use of inotropes and/or vasopressors for at least twelve hours after post-surgery ICU admission to qualify as the prolonged postoperative use of catecholamines (PPUC). The RDW was obtained from the routine full blood count analysis performed upon admission or a maximum of 72 h before surgery. We also performed a multivariable logistic regression analysis with PPUC as the dependent variable. Results: We finally enrolled 343 patients. Upon multivariate analysis, RDW >14.4% was independently associated with prolonged postoperative catecholamine use when compared to the reference group (OR 2.62 [1.06-4.84]; p = 0.03). Moreover, the EuroSCORE II score (OR 1.38 [1.03-1.85]; p = 0.03), the cross-clamp time (OR 1.01 [1.01-1.02]; p < 0.01), and robot-assisted mitral valve surgery (OR 0.53 [0.30-0.93]; p < 0.03) were independently associated with the prolonged postoperative use of catecholamines. Conclusions: This study identified that an elevated preoperative RDW (>14.4%), the EuroSCORE II score, and the cross-clamp time independently predict prolonged postoperative catecholamine use in minimally invasive mitral valve surgery patients. Conversely, the robot-assisted approach was associated with a smaller hemodynamic impairment.

A comparison between robotic-assisted and open approaches for large ventral hernia repair-a multicenter analysis of 30days outcomes using the ACHQC database.

Over the last few decades, there has been an increase in the use of a minimally invasive (MIS) approach for complex hernias involving component separation. A robotic platform provides better visualization and mobilization of tissues for component separation. We aim to assess the outcomes of open and robotic-assisted approaches for large VHR utilizing the ACHQC national database. A retrospective review of prospectively collected data from the Abdominal Core Health Quality Collaborative (ACHQC) was performed to include all adult patients who had primary and incisional midline ventral hernias larger than 10cm and underwent elective open and robotic hernia repairs with mesh from January 2013 to March 2023. Univariate and multivariate analyses were performed comparing Open and Robotic approaches. The ACHQC database identified 5,516 patients with midline hernias larger than 10cm who underwent VHR. The open group (OG) had 4,978 patients, and the robotic group (RG) had 538. The RG had a higher median BMI (33.3kg/m2 (IQR 29.8-38.1) vs 32.7 (IQR 28.7-36.6) (p < 0.001). Median hernia width was 15cm (IQR 12-18) in the OG and 12cm in the RG (10-14) (p < 0.001). Sublay positioning of the mesh was the most common. The fascial closure was higher in the RG (524; 97% versus 4,708; 95%-p = 0.005). Median Length of Stay (LOS) was 5days (IQR 4-7) in the OG and 2days (IQR 1-3) in the RG (p < 0.001). The readmission rate was higher in the OG (n = 374; 7.5% vs n = 16; 3%; p < 0.001). 30-day SSI were higher in the OG (343; 6.9%% vs 14; 2.6%; p < 0.001). Logistic regression analysis identified diabetes (OR 1.6; CI 1.1-2.1; p = 0.006) and BMI (OR 1.04, CI 1.02-1.06; p < 0.001) as predictors of SSIs, while the robotic approach was protective (OR 0.35, CI 0.17-0.64; p = 0.002). For SSO, logistic regression showed BMI (OR 1.04, CI 1.03-1.06; p < 0.001) and smoking (OR 1.8, CI 1.3-2.4; p < 0.001) as predictors Robotic approach was associated with lower readmission rates (OR .04, CI 0.2-0.6; p < 0.001). A robotic approach improves early 30-day outcomes compared to an open technique for large VHR. There was no difference in SSO at 30days.

Systematic Review of Robotic-Assisted Peripheral and Central Lymphatic Surgery.

Robotic-assisted lymphatic reconstruction has gained increasing interest over the past few years. The aim of this study was to systematically investigate the benefits of robotic-assisted lymphatic surgery based on currently published literature. A systematic review evaluating the feasibility, surgical aspects, and both objective and subjective improvements in patients with impairment of the peripheral or central lymphatic system was performed according to the PRISMA guidelines. The review was registered on PROSPERO. The literature search yielded 328 articles after the removal of duplicates, followed by a full-text review of the 29 articles, out of which a total of 11 relevant articles were deemed eligible. Among these, seven used a retrospective design and four a prospective design. All studies included confirmed the feasibility of robotic-assisted lymphatic surgery and reported promising results concerning both technical aspects and patient-related outcomes. However, currently, only a limited number of studies directly compare the robotic-assisted approach to the manual approach, and these studies have limited statistical analyses. Despite the heterogeneous measurands, all studies showed the feasibility of robotic-assisted lymphatic surgery, and seven provided promising data on patient-related outcomes. Additional studies are needed to further identify future directions in robotic-assisted lymphatic surgery.

Fully Telemetric Robotic Microsurgery: Clinical Experience With 23 Cases.

Recently, there is an ongoing trend in plastic surgery with robotic-assisted microsurgery and supermicrosurgery devices being developed. Combining a telemetrically controlled robotic microscope with an also telemetrically controlled microsurgery robot unlocks synergistic effects with complete disconnection of the operating surgeon from the operating field. Here, we report the first clinical free flap reconstructions using this setup. Twenty-three surgeries were performed with the combined remote approach using the Symani Surgical System and the RoboticScope in open microsurgery procedures. Anastomosis time and ischemia time were recorded. The surgical performance for anastomoses was assessed using the modified Structured Assessment of Microsurgical Skills (SAMS) score. Subjective satisfaction was evaluated by the surgeons in comparison with conventional microsurgery. To evaluate the learning curve, the senior authors first four (first group) and last four (last group) procedures were compared. Overall, flap survival was 95.7%. The average arterial anastomosis time was 36.7 ± 10.9 min. Total time of surgery was 277.7 ± 63.8 min, and ischemia time was 100.6 ± 24.9 min. Most SAMS score parameters were significantly higher in the last group of surgical procedures compared with the first operations. Subjective satisfaction was equal or better with the combined robotic-assisted approach in most categories. Our data demonstrates safety and feasibility of the use of a combined remote approach. Robotic systems for microsurgical procedures may hold promising potential for improvement of surgical quality and open up new frontiers in microsurgery.
