Robotic-assisted versus laparoscopic repair of type II, III and IV hiatal hernias: A retrospective study comparing adverse outcomes

Objective:Robotic-assisted surgery(RAS)is continuing to expand in use in surgical specialties,including foregut surgery.The available data on its use in large hiatal hernia(HH)repair are limited and conflicting.This study sought to determine whether there are significant differences in adverse outcomes following HH repair performed with a robotic approach vs.a laparoscopic approach.This study was limited to outcomes in patients with type II,III,and IV HHs,as these hernias are typically more challenging to repair.Methods:A retrospective analysis was performed from data obtained from TriNetX,a large deidentified clinical database,over a 10-year period.Adult patients who underwent type II,III,or IV HH repair were included in the study.HH with robotic repair was compared to laparoscopic repair.Cohorts were propensity score matched for demographic information and comorbidities.Risk ratios,risk differences(RDs)with 95%confidence intervals(CIs),and t test for each examined adverse outcome were used to estimate the effects of robotic repair vs.laparoscopic repair.Results:In total,20,016 patients who met the inclusion criteria were identified;1,515 patients utilized RAS,and 18,501 used laparoscopy.Prior to matching,there were significant differences in age,sex,comorbidity,and BMI between the two cohorts.After 1:1 propensity score matching,analyses of 1,514 well-matched patient pairs revealed no significant differences in demographics or comorbidities.Patients who underwent robotic repair were more likely to experience major complications,including venous thromboembolism(RD:0.007,95%CI:0.003,0.011;p?0.002),critical care(RD:0.023,95%CI:0.007,0.039;p?0.004),urinary/renal complications(RD:0.027,95%CI:0.014,0.041;p<0.001),and respiratory complications(RD:0.046,95%CI:0.028,0.064;p<0.001).RAS was associated with a significantly shorter length of stay(32.4±27.5 h vs.35.7±50.1 h,p?0.031),although this finding indicated a reduction in the length of stay of less than 4 hours.No statistically significant differences in risk of esophageal perforation,infection,postprocedural shock,bleeding,mortality,additional emergency room visits,cardiac complications,or wound disruption were found.Conclusions:Patients who undergo robotic-assisted large HH repair are at increased risk of venous thromboembolism,need critical care,urinary or renal complications and respiratory complications.Due to variations in RAS technique,experience,and surgical volumes,further study of this surgical approach and complication rates is warranted.

Managerial perspectives of scaling up robotic-assisted surgery in healthcare systems:A systematic literature review

Objectives Robotic-assisted surgery(RAS)is a minimally invasive technique practiced in multiple specialties.Standard training is essential for the acquisition of RAS skills.The cost of RAS is considered to be high,which makes it a burden for institutes and unaffordable for patients.This systematic literature review(SLR)focused on the various RAS training methods applied in different surgical specialties,as well as the cost elements of RAS,and was to summarize the opportunities and challenges associated with scaling up RAS.Methods An SLR was carried out based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses reporting guidelines.The PubMed,EBSCO,and Scopus databases were searched for reports from January 2018 through January 2024.Full-text reviews and research articles in the English language from Asia-Pacific countries were included.Articles that outlined training and costs associated with RAS were chosen.Results The most common training system is the da Vinci system.The simulation technique,which includes dry-lab,wet-lab,and virtual reality training,was found to be a common and important practice.The cost of RAS encompasses the installation and maintenance costs of the robotic system,the operation theatre rent,personnel cost,surgical instrument and material cost,and other miscellaneous charges.The synthesis of SLR revealed the challenges and opportunities regarding RAS training and cost.Conclusions The results of this SLR will help stakeholders such as decision-makers,influencers,and end users of RAS to understand the significance of training and cost in scaling up RAS from a managerial perspective.For any healthcare innovation to reach a vast population,cost-effectiveness and standard training are crucial.

Robotic-assisted proctosigmoidectomy for Hirschsprung’s disease:A multicenter prospective study

BACKGROUND Robotic surgery is a cutting-edge minimally invasive technique that overcomes many shortcomings of laparoscopic techniques,yet few studies have evaluated the use of robotic surgery to treat Hirschsprung’s disease(HSCR).AIM To analyze the feasibility and medium-term outcomes of robotic-assisted proctosigmoidectomy(RAPS)with sphincter-and nerve-sparing surgery in HSCR patients.METHODS From July 2015 to January 2022,156 rectosigmoid HSCR patients were enrolled in this multicenter prospective study.Their sphincters and nerves were spared by dissecting the rectum completely from the pelvic cavity outside the longitudinal muscle of the rectum and then performing transanal Soave pull-through procedures.Surgical outcomes and continence function were analyzed.RESULTS No conversions or intraoperative complications occurred.The median age at surgery was 9.50 months,and the length of the removed bowel was 15.50±5.23 cm.The total operation time,console time,and anal traction time were 155.22±16.77,58.01±7.71,and 45.28±8.15 min.There were 25 complications within 30 d and 48 post-30-d complications.For children aged≥4 years,the bowel function score(BFS)was 17.32±2.63,and 90.91%of patients showed moderate-to-good bowel function.The postoperative fecal continence(POFC)score was 10.95±1.04 at 4 years of age,11.48±0.72 at 5 years of age,and 11.94±0.81 at 6 years of age,showing a promising annual trend.There were no significant differences in postoperative complications,BFS,and POFC scores related to age at surgery being≤3 mo or>3 mo.CONCLUSION RAPS is a safe and effective alternative for treating HSCR in children of all ages;it offers the advantage of further minimizing damage to sphincters and perirectal nerves and thus providing better continence function.

Clinical outcomes of robotic-assisted and manual total hip arthroplasty in the same patient:A case report

BACKGROUND Total hip arthroplasty(THA)is an effective treatment for advanced osteonecrosis of the femoral head,which can significantly relieve pain and improve patients'quality of life.Robotic-assisted THA enhances the accuracy and stability of THA surgery and achieves better clinical outcomes than manual THA.CASE SUMMARY We report the clinical outcomes of robotic-assisted THA and manual THA in the same patient with osteonecrosis of the femoral head.A 49-year-old male patient attended our hospital due to more than 3 years of pain in both hip joints.The left hip was treated with robotic-assisted THA.The patient underwent manual THA of the right hip 3 mo after robotic-assisted THA.We obtained postoperative radiograph parameters,Harris hip score and forgotten joint score of the patient 1 year after surgery.CONCLUSION Compared with manual THA,the patient’s left hip felt better 1 year after roboticassisted THA.Robotic-assisted THA resulted in a better Harris hip score and forgotten joint score than manual THA in the same patient with osteonecrosis of the femoral head.

Coordinated control strategy for robotic-assisted gait training with partial body weight support

Walking is the most basic and essential part of the activities of daily living. To enable the elderly and non-ambulatory gait-impaired patients, the repetitive practice of this task, a novel gait training robot(GTR) was designed followed the end-effector principle, and an active partial body weight support(PBWS) system was introduced to facilitate successful gait training. For successful establishment of a walking gait on the GTR with PBWS, the motion laws of the GTR were planned to enable the phase distribution relationships of the cycle step, and the center of gravity(COG) trajectory of the human body during gait training on the GTR was measured. A coordinated control strategy was proposed based on the impedance control principle. A robotic prototype was developed as a platform for evaluating the design concepts and control strategies. Preliminary gait training with a healthy subject was implemented by the robotic-assisted gait training system and the experimental results are encouraging.

Robotic-assisted cholecystectomy: Current status and future application

Robotic-assisted cholecystectomy(RC)is increasingly common.However,its exact role remains unde-fined,with multiport conventional laparoscopic cholecystectomy(LC)being regarded as the established gold standard.This review aims to provide an overview of the evidence for RC and to define its current and future role.A literature search was performed on the PubMed and Medline databases to identify relevant articles published between 1994 and February 2022.The evidence obtained was summarised in a narrative style.Greater emphasis was placed on recent 10-year articles and studies of higher meth-odological quality.RC is noninferior to LC.The robotic platform facilitates the application of minimally invasive surgery in a way conventional laparoscopy cannot.LC remains appropriate for the majority of patients requiring cholecystectomy.The advantages of RC include inherent technical benefits,facilitating the learning of new surgical technology and its potential to reduce the risk of open conversion and bile leakage in certain populations(Mirizzi syndrome,complicated calculous disease,chronic liver disease and possibly malignancy).It also has increasing applicability to related biliary surgery.The limitations include cost,loss of tactile feedback and the learning curve associated with initial implementation.Future applications of robotic surgical systems include utilisation in difficult cholecystectomy,cases of biliary malignancy,telerobotic surgery and telementoring.

Laparoscopic Observations in Acquired Inguinal Hernia before and after Robotic-Assisted Laparoscopic Prostatectomy

Background: The mechanism of the development of acquired inguinal hernia, especially indirect inguinal hernia, is not well known. Although anatomical studies have been performed to explain development of inguinal hernia, they have mainly involved autopsy or temporal findings at the time of hernioplasty. To elucidate the pattern of development of acquired inguinal hernia, we studied the occurrence of inguinal hernia after robotic-assisted laparoscopic prostatectomy (RALP). Methods: From March 2009 to November 2011, RALP for prostatic cancer was performed on 60 patients in our institute. The RALP was performed by one urologist using the da Vinci Surgical System. The postsurgical development of inguinal hernia was diagnosed based on patients’ symptoms. Seven patients were treated with laparoscopic hernioplasty, and one underwent mesh-plug repair. Using video recordings, the laparoscopic findings during RALP and laparoscopic hernioplasty were compared among all patients. Results: Seven of 59 patients (11.9%) developed an inguinal hernia. One patient had a pre-existing pantaloon inguinal hernia at the time of RALP. Eleven inguinal lesions in the seven patients who underwent laparoscopic hernioplasty were reviewed, and all were indirect inguinal hernias. Conclusion: A main factor in the development of inguinal hernia after RALP could be a combination of outer-side intact layers and inner-side hard scar of the inguinal ring, which seems like “out swing door”.

Intraoperative Ureteral Identification Utilizing StimSite™ Technology during Robotic-Assisted Sacral Colpopexy Procedure: A Case Report

Identification of the pelvic ureter location is crucial during robotic-assisted sacral colpopexy procedures to avoid iatrogenic injury. In this case study, StimSite&#8482 technology (Allotrope Medical;Houston, TX) was used to assist with ureter identification. StimSite is a novel, minimally invasive surgical device designed to facilitate ureter identification by delivering on-demand mild electrical impulses to stimulate visible ureteral peristalsis. Visualization of the ureter can help prevent inadvertent injury which can cause significant patient morbidity, and in some cases mortality. The use of StimSite permitted ureter mapping along the pelvic sidewall and assisted with creating the proper peritoneal dissection for synthetic mesh placement. StimSite provides a minimally invasive, time-conscious option for real-time ureter identification during robotic-assisted sacral colpopexy procedures.

Trends in hospital readmissions and emergency room visits 60 days after robotic-assisted and laparoscopic hysterectomy

Objective:Hospital readmission after surgery is one of the major contributors to the increased healthcare cost.Robotic-assisted hysterectomy(RAH)is an innovative surgical procedure most commonly performed within the last decade.The purpose of this study was to analyze the effects on hospital readmission patterns and emergency room(ER)visits within 60 days of discharge for women who had RAH versus laparoscopic hysterectomy(LH)in an academic community hospital in Texas.Method:We performed a retrospective study of women with RAH or LH.We used the univariate and multivariate logistic regression to examine the impact of patients'risk factors,the type of surgery,age,number of comorbidities,and duration of surgery on the 60-day hospital readmissions and ER visits.Results:A total of 291 cases with RAH or LH for benign and malignant indications were examined.The number of comorbidities and duration of surgery were similar between the two treatment groups(p>0.05).Patients in the RAH group were younger than the LH group(RAH:45.4±9.9 y,LH:49.8±11.5 y,p<0.05).No significant difference neither in hospital readmission or ER visits between the two groupswas observed(p?0.544 and p=0.109,respectively).Younger age and longer duration of surgery were significantly associated with a higher risk of ER visits(p<0.05).Conclusion:RAH is comparable with LH in hospital readmissions and ER visits.The younger age and longer operation time could lead to ER visits.

Robot-assisted partial splenectomy for benign splenic tumors:Four case reports

BACKGROUND Robotic-assisted partial splenectomy(RAPS)is a superior approach for treating splenic cysts and splenic hemangiomas,as it preserves the immune function of the spleen and reduces the risk of overwhelming post splenectomy infection.Curren-tly,there are no standardized guidelines for performing a partial splenectomy.CASE SUMMARY Four patients with splenic cysts or splenic hemangiomas were treated by RAPS.Critical aspects with RAPS include carefully dissecting the splenic pedicle,accurately identifying and ligating the supplying vessels of the targeted segment,and ensuring precise hemostasis during splenic parenchymal transection.Four successful RAPS cases are presented,where the tumors were removed by pret-reating the splenic artery,dissecting and ligating the corresponding segmental vessels of the splenic pedicle,transecting the ischemic segment of the spleen,and using electrocautery for optimal hemostasis.Four patients underwent successful surgeries with minimal bleeding during the procedure,and there were no signs of bleeding or recurrence postoperatively.CONCLUSION Four cases confirm the feasibility and superiority of RAPS for the treatment of benign splenic tumors.

Learning curves of resection and reconstruction procedures in robotic-assisted pancreatoduodenectomy by a single surgeon:a retrospective cohort study of 160 consecutive cases

Background:Robotic-assisted pancreatoduodenectomy(RPD)has been routinely performed in a few of centers worldwide.This study aimed to evaluate the perioperative outcomes and the learning curves of resection and reconstruction procedures in RPD by one single surgeon.Methods:Consecutive patients undergoing RPD by a single surgeon at the First Affiliated Hospital of Sun Yat-sen University(Guangzhou,China)between July 2016 and October 2022 were included.The perioperative outcomes and learning curves were retrospectively analysed by using cumulative sum(CUSUM)analyses.Results:One-hundred and sixty patients were included.According to the CUSUM curve,the times of resection and reconstruction procedures were shortened significantly after 30 cases(median,284 vs 195 min;P<0.001)and 45 cases(median,138 vs 120 min;P<0.001),respectively.The estimated intraoperative blood loss(median,100 vs 50 mL;P<0.001)and the incidence of clinically relevant post-operative pancreatic fistula(29.2%vs 12.5%;P=0.035)decreased significantly after 20 and 120 cases,respectively.There were no significant differences in the total number of lymph nodes examined,post-operative major complications,or post-operative length-of-stay between the two groups.Conclusions:Optimization of the resection procedure and the acquisition of visual feedback facilitated the performance of RPD.RPD was a safe and feasible procedure in the selected patients.

Evaluation of the short-term outcomes of robotic-assisted radical resection for perihilar cholangiocarcinoma:a propensity-scored matching analysis

Background:The application of robotic-assisted radical resection in perihilar cholangiocarcinoma(pCCA)remains poorly defined.This study aimed to evaluate the safety and efficacy of robotic-assisted radical resection for pCCA in our institute.Methods:Between July 2017 and July 2022,pCCA patients undergoing robotic-assisted and open radical resection at First Affiliated Hospital of Sun Yat-sen University(Guangzhou,China)were included.The short-term outcomes were compared by using propensity-scored matching(PSM)analysis.Results:Eighty-six pCCA patients were enrolled.After PSM at a ratio of 1:2,10 and 20 patients were assigned to the roboticassisted and open groups,respectively.There were no significant disparities in the clinicopathological features between the two groups.The robotic-assisted group had significantly longer operation time(median:548 vs 353 min,P=0.004)and larger total number of lymph nodes examined(median:11 vs 5,P=0.010)than the open group.The robotic-assisted group tended to have a lower intraoperative blood loss(median:125 vs 350 mL,P=0.067),blood transfusion rates(30.0%vs 70.0%,P=0.056),and post-operative overall morbidities(30.0%vs 70.0%,P=0.056)than the open group,even though the differences were not statistically significant.There were no significant differences in the negative resection margin,post-operative major morbidities,or post-operative length-of-stay between the robotic-assisted and open groups(all P>0.05).Conclusions:Robotic-assisted radical resection of pCCA may get a larger total number of lymph nodes examined than open surgery.Provided robotic-assisted surgery may be a feasible and safe technique for selected pCCA patients.

Is HPB robotic-assisted surgery an evolution or a revolution in laparoscopy?

Robotic-assisted surgery technology demonstrates a new prospect for surgery.Its advantages are particularly prominent in specific surgery divisions or for specific surgical procedures,which has set off a new wave of surgical technology following laparoscopic surgery.Looking back at the history of surgical development over the past century,there have been many technological waves,some of which have become classics and standards,some of which are constantly evolving,and some of which have been gradually abandoned in practice.In the context of the increasingly mature and accurate laparoscopic surgery,which has become a standard operation of many types of surgery,the government,medical institutions and surgeons should carefully consider the role and future development of robotic-assisted surgery.

Robotic-assisted bronchoscopy in the diagnosis of peripheral pulmonary lesions

More peripheral pulmonary lesions(PPLs)are detected by low-dose helical computed tomography(CT)either in-cidentally or via dedicated lung cancer screening programs.Thus,using methods for safe and accurate diagnosis of these lesions has become increasingly important.Transthoracic needle aspiration(TTNA)and transbronchial lung biopsy(TBLB)are routinely performed during the diagnostic workup for PPLs.However,TTNA often car-ries the risk of pneumothorax,uncontrollable airway hemorrhage,and does not allow mediastinal staging in one procedure.In contrast,traditional TBLB often has a poorer diagnostic yield despite fewer complications.With the ongoing development of technology applied to bronchoscopy,guided bronchoscopy has become widely used and the diagnostic yield of TBLB has improved.Additionally,guided bronchoscopy continues to demonstrate a better safety profile than TTNA.In recent years,robotic-assisted bronchoscopy(RAB)has been introduced and imple-mented in the diagnosis of PPLs.At present,RAB has two platforms that are commercially available:Monarch TM and Ion TM;several other platforms are under development.Both systems differ in characteristics,advantages,and limitations and offer features not seen in previous guided bronchoscopy.Several studies,including cadaveric model studies and clinical trials,have been conducted to examine the feasibility and performance of RAB using these two systems;large multicenter studies are underway.In this review,published experimental results,focus-ing on diagnostic yield and complications of RAB,are analyzed and the potential clinical application of RAB is discussed,which will enable the operators to have a clear overview of RAB.
