METHODS: A literature search was performed to identify comparative studies reporting perioperative outcomes for RS and LS for rectal cancer. Pooled odds ratios and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were calculated using either the fixed effects model or random effects model. RESULTS: Eight studies matched the selection criteria and reported on 661 subjects, of whom 268 underwent RS and 393 underwent LS for rectal cancer. Compared the perioperative outcomes of RS with LS, reports of RS indicated favorable outcomes considering conversion(WMD: 0.25; 95% CI: 0.11-0.58; P = 0.001). Meanwhile, operative time (WMD: 27.92, 95% CI: -13.43 to 69.27; P = 0.19); blood loss (WMD: -32.35, 95% CI: -86.19 to 21.50; P = 0.24); days to passing flatus (WMD: -0.18, 95% CI: -0.96 to 0.60; P = 0.65); length of stay (WMD: -0.04; 95% CI: -2.28 to 2.20; P = 0.97); complications (WMD: 1.05; 95% CI: 0.71-1.55; P = 0.82) and pathological details, including lymph nodes harvested (WMD: 0.41, 95% CI: -0.67 to 1.50; P = 0.46), distal resection margin (WMD: -0.35, 95% CI: -1.27 to 0.58; P = 0.46), and positive circumferential resection margin (WMD: 0.54, 95% CI: 0.12-2.39; P = 0.42) were similar between RS and LS. CONCLUSION: RS for rectal cancer is superior to LS in terms of conversion. RS may be an alternative treatment for rectal cancer. Further studies are required.展开更多

The patients all had a diagnosis of middle and low rectal adenocarcinoma with stage I-III disease. The median follow-up period was 37.4 mo. Perioperative results, morbidity a pathological data were evaluated and compared. The 3-year overall survival and disease-free survival rates were calculated and compared.RESULTS: Patients were comparable in terms of preoperative and demographic parameters. The median surgery time was 192 min for laparoscopic TME (L-TME) and 342 min for robotic TME (R-TME) (P < 0.001). There were no differences found in the rates of conversion to open surgery and morbidity. The patients who underwent laparoscopic surgery stayed in the hospital two days longer than the robotic group patients (8 d for L-TME and 6 d for R-TME, P < 0.001). The pathologic evaluation showed a higher number of harvested lymph nodes in the robotic group (18 for R-TME, 11 for L-TME, P < 0.001) and a shorter distal resection margin for laparoscopic patients (1.5 cm for L-TME, 2.5 cm for R-TME, P < 0.001). The three-year overall survival and disease-free survival rates were similar between groups.CONCLUSION: Both L-TME and R-TME achieved acceptable clinical and oncologic outcomes. The robotic technique showed some advantages in rectal surgery that should be validated by further studies.展开更多

With the assistance of robotic surgical systems, maxillofacial surgery is performed with less blood loss, fewer complications, shorter hospitalization and better cosmetic results than standard open surgery.However, the application of robotic surgery techniques to the treatment of head and neck diseases remains in an experimental stage, and the long-lasting effects on surgical morbidity, oncologic control and quality of life are yet to be established. More well-designed studies are needed before this approach can be recommended as a standard treatment paradigm. Nonetheless,robotic surgical systems will inevitably be extended to maxillofacial surgery. This article reviews the current clinical applications of robotic surgery in the head and neck region and highlights the benefits and limitations of current robotic surgical systems.展开更多

METHODS: Using a prospective database, the patients undergoing fully robotic surgery for biliary malignan- cies between January 2009 and January 2011 were in- cluded. Records of patients with confirmed malignancy were reviewed for clinicopathological data and informa- tion about PSM. RESULTS: Sixty-four patients with biliary tract cancers underwent robotic surgery, and sixty patients met the inclusion criteria. The median age was 67 year (range: 40-85 year). During a median 15-mo follow-up period, two female patients were detected solitary PSM after robotic surgery. The incidence of PSM was 3.3%. Pa- tient 1 underwent robotic anatomatic left hemihepa- tectomy and extraction of biliary tumor thrombi for an Klatskin tumor. She had a subcutaneous mass located at the right lateral abdominal wall near a trocar scar. Patient 2 underwent robotic pancreaticoduodenectomy for distal biliary cancer. She had two metachronous subcutaneous mass situated at the right lateral abdomi- nal wall under a same trocar scar at 7 and 26 mo. The pathology of the excised PSM masses confirmed meta- static biliary adenocarcinoma. CONCLUSION: The incidence of PSIVls after robotic surgery for biliary malignancies is relatively low, and biliary cancer can be an indication of robotic surgery.展开更多

文摘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.
文摘There have been nearly 60 years since Thomas Starzl’s first liver transplant.During this period,advancements in medical technology have progressively enabled the adoption of new methods for transplantation.Among these innovations,robotic surgery has emerged in recent decades and is gradually being integrated into transplant medicine.Robotic hepatectomy and liver implantation represent significant advancements in the field of transplant surgery.The precision and minimally invasive nature of robotic surgery offer substantial benefits for both living donors and recipients.In living donors,robotic hepatectomy reduces postoperative pain,minimizes scarring,and accelerates recovery.For liver recipients,robotic liver implantation enhances surgical accuracy,leading to better graft positioning and vascular anastomosis.Robotic systems provide more precise and maneuverable control of instruments,allowing surgeons to perform complex procedures with greater accuracy and reduced risk to patients.This review encompasses publications on minimally invasive donor liver surgery,with a specific focus on robotic liver resection in transplantation,and aims to summarize current knowledge and the development status of robotic surgery in liver transplantation,focusing on liver resection in donors and graft implantation in recipients.

文摘BACKGROUND Da Vinci Robotics-assisted total mesorectal excision(TME)surgery for rectal cancer is becoming more widely used.There is no strong evidence that roboticassisted surgery and laparoscopic surgery have similar outcomes in elderly patients with TME for rectal cancer.AIM To determine the improved oncological outcomes and short-term efficacy of robot-assisted surgery in elderly patients undergoing TME surgery.METHODS A retrospective study of the clinical pathology and follow-up of elderly patients who underwent TME surgery at the Department of Gastrointestinal Oncology at the Affiliated Hospital of Nanjing University of Chinese Medicine was conducted from March 2020 through September 2023.The patients were divided into a robotassisted group(the R-TME group)and a laparoscopic group(the L-TME group),and the short-term efficacy of the two groups was compared.RESULTS There were 45 elderly patients(≥60 years)in the R-TME group and 50 elderly patients(≥60 years)in the L-TME group.There were no differences in demographics,conversion rates,or postoperative complication rates.The L-TME group had a longer surgical time than the R-TME group[145(125,187.5)vs 180(148.75,206.25)min,P=0.005),and the first postoperative meal time in the L-TME group was longer than that in the R-TME(4 vs 3 d,P=0.048).Among the sex and body mass index(BMI)subgroups,the R-TME group had better out-comes than did the L-TME group in terms of operation time(P=0.042)and intraoperative assessment of bleeding(P=0.042).In the high BMI group,catheter removal occurred earlier in the R-TME group than in the L-TME group(3 vs 4 d,P=0.001),and autonomous voiding function was restored.CONCLUSION The curative effect and short-term efficacy of robot-assisted TME surgery for elderly patients with rectal cancer are similar to those of laparoscopic TME surgery;however,robotic-assisted surgery has better short-term outcomes for individuals with risk factors such as obesity and pelvic stenosis.Optimizing the learning curve can shorten the operation time,reduce the recovery time of gastrointestinal function,and improve the prognosis.
文摘Background: Epiphrenic Diverticulum is frequently associated with esophageal motility disorders, such as nutcrackers esophagus. The diagnosis is usually made using imaging studies such as a Barium esophagogram, and esophageal manometry. Surgical treatment options for epiphrenic diverticulum and EN include diverticulectomy and wide myotomy. Aim: The resection of three epiphrenic diverticula and extensive myotomy were performed by robotic thoracoscopy uneventfully. Case presentation: A 65-year-old female complaining of dysphagia for solid foods, Chest pain and regurgitation. Esophagogastroduodenoscopy (EDG) with difficulty in advancing the endoscope at 25 cm and demonstrating an ED, no hiatal hernia and normal stomach and duodenum. Barium Esophagogram showed multiple diverticula and tortuosity throughout the esophagus.

文摘BACKGROUND Robotic resection using the natural orifice specimen extraction surgery I-type F method(R-NOSES I-F)is a novel minimally invasive surgical strategy for the treatment of lower rectal cancer.However,the current literature on this method is limited to case reports,and further investigation into its safety and feasibility is warranted.AIM To evaluate the safety and feasibility of R-NOSES I-F for the treatment of low rectal cancer.METHODS From September 2018 to February 2022,206 patients diagnosed with low rectal cancer at First Affiliated Hospital of Nanchang University were included in this retrospective analysis.Of these patients,22 underwent R-NOSES I-F surgery(RNOSES I-F group)and 76 underwent conventional robotic-assisted low rectal cancer resection(RLRC group).Clinicopathological data of all patients were collected and analyzed.Postoperative outcomes and prognoses were compared between the two groups.Statistical analysis was performed using SPSS software.RESULTS Patients in the R-NOSES I-F group had a significantly lower visual analog score for pain on postoperative day 1(1.7±0.7 vs 2.2±0.6,P=0.003)and shorter postoperative anal venting time(2.7±0.6 vs 3.5±0.7,P<0.001)than those in the RLRC group.There were no significant differences between the two groups in terms of sex,age,body mass index,tumor size,TNM stage,operative time,intrao-perative bleeding,postoperative complications,or inflammatory response(P>0.05).Postoperative anal and urinary functions,as assessed by Wexner,low anterior resection syndrome,and International Prostate Symptom Scale scores,were similar in both groups(P>0.05).Long-term follow-up revealed no significant differences in the rates of local recurrence and distant metastasis between the two groups(P>0.05).CONCLUSION R-NOSES I-F is a safe and effective minimally invasive procedure for the treatment of lower rectal cancer.It improves pain relief,promotes gastrointestinal function recovery,and helps avoid incision-related complications.
文摘Objective To report the outcomes of intra-and extra-peritoneal robot-assisted radical prostatectomy(RARP)and robot-assisted radical cystectomy(RARC)with Hugo™robot-assisted surgery(RAS)system(Medtronic,Minneapolis,MN,USA).Methods Data of twenty patients who underwent RARP and one RARC at our institution between February 2022 and January 2023 were reported.The primary endpoint of the study was to report the surgical setting of Hugo™RAS system to perform RARP and RARC.The secondary endpoint was to assess the feasibility of RARP and RARC with this novel robotic platform and report the outcomes.Results Seventeen patients underwent RARP with a transperitoneal approach,and three with an extraperitoneal approach;and one patient underwent RARC with intracorporeal ileal conduit.No intraoperative complications occurred.Median docking and console time were 12(interquartile range[IQR]7-16)min and 185(IQR 177-192)min for transperitoneal RARP,15(IQR 12-17)min and 170(IQR 162-185)min for extraperitoneal RARP.No intraoperative complications occurred.One patient submitted to extraperitoneal RARP had a urinary tract infection in the postoperative period that required an antibiotic treatment(Clavien-Dindo Grade 2).In case of transperitoneal RARP,two minor complications occurred(one pelvic hematoma and one urinary tract infection;both Clavien-Dindo Grade 2).Conclusion Hugo™RAS system is a novel promising robotic platform that allows to perform major oncological pelvic surgery.We showed the feasibility of RARP both intra-and extra-peritoneally and RARC with intracorporeal ileal conduit with this novel platform.
文摘Objective Although robotic surgery adoption and its indications are growing worldwide,for multiple factors,including costs,there is a lack of training and experience.Our aim was to study the impact of a robotic introduction training program on gesture performance,such as suturing,in robot-naive individuals.Methods Using the DaVinci robot,a 2-hour program was based on virtual reality and anatomical model exercises.All participants performed 3 repetitions of virtual reality exercises on the virtual simulator,and then performed and were assessed on 2 tests,ie robot and laparoscopic training box.After the course,the participants were surveyed for this training program.Results Twenty-seven residents and surgeons were enrolled in the training program.With only 2 hours of training,all of the participants were able to complete the training program,thus learning generic and specific skills in robotic surgery.In virtual reality exercise,the scores of the 3 exercises increased significantly with every repetition(p<0.001)and the size of the increase was large.The completion time on the robot platform was 2.6 times faster(169.33±28.28 s vs.447.96±156.55 s,p<0.001)than that in the laparoscopic box,and the difference between both types of tests was large(pη2=0.797).The centralization and passage of the needle were significantly better on the robot platform(5 vs.3,p<0.001,r=0.47;5 vs.4,p<0.001,r=0.59)than in the laparoscopic box.For the intracorporeal stitch+knot test,every participant was able to perform the exercise on the robot but only 85.2%(23/27)in the laparoscopic box.Twenty-one participants answered the survey,and 13(61.9%)of them considered robotic performance independent of laparoscopic experience.Conclusions Surgeons are interested and seek training in robotic surgery.We implemented the first hands-on robotic surgery training program in Portugal and participants considered it was important and adequate for its purpose.All participants,even without robotic experience,learned quicker,performed better,faster and more precisely on the robot over laparoscopy.
文摘With an ageing global population,we will see an increasing number of elderly patients with colorectal cancer(CRC)requiring surgery.However,it should be recognized that the elderly are a heterogenous group,with varying physiological and functional status.While traditionally viewed to be associated with frailty,comorbidities,and a higher risk of post operative morbidity,the advancements in minimally invasive surgery(MIS)and improvements in perioperative care have allowed CRC surgery to be safe and feasible in the elderly-chronological age alone should therefore not strictly be an exclusion criterion for curative surgery.However,as a form of MIS,laparoscopic assisted colorectal surgery(LACS)has the inherent disadvantages of:(1)Dependence on a trained assistant for retraction and laparoscope control;(2)The loss of wristed movement with reduced dexterity and suboptimal ergonomics;(3)A lack of intuitive movement due to the levering effect of trocars;and(4)An amplification of physiological tremors.Representing a technical evolution of LACS,robotic assisted colorectal surgery was introduced to overcome these limitations.In this minireview,we examine the evidence for robotic surgery in the elderly with CRC.
文摘BACKGROUND In recent years,minimally invasive liver resection has become a standard of care for liver tumors.Considering the need to treat increasingly fragile patients,general anesthesia is sometimes avoided due to respiratory complications.Therefore,surgical treatment with curative intent is abandoned in favor of a less invasive and less radical approach.Epidural anesthesia has been shown to reduce respiratory complications,especially in elderly patients with pre-existing lung disease.CASE SUMMARY A 77-year-old man with hepatitis-C-virus-related chronic liver disease underwent robotic liver resection for hepatocellular carcinoma.The patient was suffering from hypertension,diabetes and chronic obstructive pulmonary disease.The National Surgical Quality Improvement Program score for developing pneumonia was 9.2%.We planned a combined spinal–epidural anesthesia with conscious sedation to avoid general anesthesia.No modification of the standard surgical technique was necessary.Hemodynamics were stable and bleeding was minimal.The postoperative course was uneventful.CONCLUSION Robotic surgery in locoregional anesthesia with conscious sedation could be considered a safe and suitable approach in specialized centers and in selected patients.
文摘BACKGROUND Lymphangiomas are a group of benign swellings which are commonly seen in children.The most common sites of presentation is the head and neck region,less commonly seen in axilla,chest,liver,spleen,etc.The ideal modality of treatment has always been surgical excision irrespective of the site and age group.But with the advent of minimally invasive surgical techniques,it is now possible to perform excision of parapharyngeal space lesions with minimal morbidity and good clearance.CASE SUMMARY A 42-year-old male patient who presented with difficulty in swallowing and had undergone surgery twice outside,where Transcervical approach was attempted to remove the parapharyngeal mass,but failed.Magnetic resonance imaging scan demonstrated a 6 cm x 5 cm x 4 cm left parapharyngeal mass.He underwent transoral robotic surgery for the excision of the parapharyngeal lesion and had an uneventful post-operative recovery.CONCLUSION Lymphangiomas are hamartomatous swellings which are benign in nature.The symptoms of the patient with large parapharyngeal mass include dysphagia,dyspnoea and neck swelling.Clinicoradiological evaluation is of utmost importance to determine the adjacent vital structures and the approach to the tumor.With the advent of robotics in oncology,transoral robotic excision is one of the best approaches to perform such a surgery.
文摘Objectives:To highlight critical preoperative and intraoperative considerations in approaching fistula repair robotically.Methods:A search of the literature was conducted to identify relevant articles pertaining to robotic management of urinary fistulae.Results:Fistulae of the genitourinary tract can be a challenging dilemma for urologists,as definitive management may require surgical intervention.Pathogenesis of both enteric and non-enteric fistulae are multifactorial,and successful repair hinges on the meticulous perioperative evaluation,planning,and execution.Traditional open techniques can subject patients to increased morbidity and prolonged hospitalizations.Since its introduction,the robotic surgical platform has continued to expand its indications.Its three-dimensional visualization and tremor free wristed instrument movements have made the robotic platform an attractive option for genitourinary fistula reconstruction.Conclusion:Robotic management of complex urinary fistulae is feasible in expert hands;more studies are needed to define its role in the treatment algorithm of this devastating conditions.
文摘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 5e23 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.
文摘Objective:To evaluate the perioperative as well as early oncological outcomes of patients undergoing robotic retroperitoneal lymph node dissection for treatment of testicular cancer.Methods:We conducted a prospective consecutive case series of patients undergoing robotic assisted retroperitoneal lymph node dissection for metastatic testicular cancer between May 2018 and July 2021 at our institution.Data were collected on patient and tumour characteristics,intraoperative and postoperative parameters,and functional and oncological outcomes.Descriptive statistics are presented.Results:Nineteen patients were identified;18(94.7%)completed the procedure robotically and one was converted to open surgery;78.9%of patients had stage≥IIB and 12(63.2%)patients had undergone prior chemotherapy.The median operative time was 300(interquartile range[IQR]240-315)min.Median blood loss was 100(IQR 50-175)mL.Median length of stay was 2(range 1-11)days.All robotically completed patients commenced diet and passed flatus on Day 1 and were discharged by Day 3.The median lymph node yield was 40.5(IQR 38-51)nodes.All patients undergoing nerve-sparing procedures recovered antegrade ejaculatory function.One patient had a Clavien-Dindo III complication(chylous ascites requiring drainage).At a median follow-up of 22.3(IQR 16.3-24.9)months,one patient developed retroperitoneal recurrence,which was successfully treated with second-line chemotherapy;no other patients have had recurrences.Conclusion:Robotic retroperitoneal lymph node dissection is a safe and feasible alternative to open surgery in appropriately selected patients,offering low morbidity.Early oncological outcomes are promising.Larger cohorts and longer follow-ups are required to validate our institution's findings.
文摘BACKGROUND Robotic surgery(RS)is gaining popularity;however,evidence for abdominoperineal resection(APR)of rectal cancer(RC)is scarce.AIM To compare the efficacy of RS and laparoscopic surgery(LS)in APR for RC.METHODS We retrospectively identified patients with RC who underwent APR by RS or LS from April 2016 to June 2022.Data regarding short-term surgical outcomes were compared between the two groups.To reduce the effect of potential confounding factors,propensity score matching was used,with a 1:1 ratio between the RS and LS groups.A meta-analysis of seven trials was performed to compare the efficacy of robotic and laparoscopic APR for RC surgery.RESULTS Of 133 patients,after propensity score matching,there were 42 patients in each group.The postoperative complication rate was significantly lower in the RS group(17/42,40.5%)than in the LS group(27/42,64.3%)(P=0.029).There wasno significant difference in operative time(P=0.564),intraoperative transfusion(P=0.314),reoperation rate(P=0.314),lymph nodes harvested(P=0.309),or circumferential resection margin(CRM)positive rate(P=0.314)between the two groups.The meta-analysis showed patients in the RS group had fewer positive CRMs(P=0.04),lesser estimated blood loss(P<0.00001),shorter postoperative hospital stays(P=0.02),and fewer postoperative complications(P=0.002)than patients in the LS group.CONCLUSION Our study shows that RS is a safe and effective approach for APR in RC and offers better short-term outcomes than LS.
文摘Multivisceral resection and/or pelvic exenteration represents the only potential curative treatment for locally advanced rectal cancer(LARC);however,it poses significant technical challenges,which account for the high risk of morbidity and mortality associated with the procedure.As complete histopathologic resection is the most important determinant of patient outcomes,LARC often requires an extended resection beyond the total mesorectal excision plane to obtain clear re-section margins.In an era when laparoscopic surgery and robot-assisted surgery are becoming commonplace,the optimal approach to extensive pelvic inter-ventions remains controversial.However,acceptance of the suitability of mini-mally invasive surgery is slowly gaining traction.Nonetheless,there is still a lack of evidence in the literature about minimally invasive approaches in multiple and extensive surgical resections,highlighting the need for research studies to explore,validate,and develop this issue.This editorial aims to provide a critical overview of the currently available applications and challenges of minimally invasive abdo-minopelvic surgery for LARC.Furthermore,we discuss recent developments in the field of robotic surgery for LARC,with a specific focus on new innovations and emerging frontiers.

文摘AIM: To conduct a meta-analysis to determine the relative merits of robotic surgery (RS) and laparoscopic surgery (LS) for rectal cancer. METHODS: A literature search was performed to identify comparative studies reporting perioperative outcomes for RS and LS for rectal cancer. Pooled odds ratios and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were calculated using either the fixed effects model or random effects model. RESULTS: Eight studies matched the selection criteria and reported on 661 subjects, of whom 268 underwent RS and 393 underwent LS for rectal cancer. Compared the perioperative outcomes of RS with LS, reports of RS indicated favorable outcomes considering conversion(WMD: 0.25; 95% CI: 0.11-0.58; P = 0.001). Meanwhile, operative time (WMD: 27.92, 95% CI: -13.43 to 69.27; P = 0.19); blood loss (WMD: -32.35, 95% CI: -86.19 to 21.50; P = 0.24); days to passing flatus (WMD: -0.18, 95% CI: -0.96 to 0.60; P = 0.65); length of stay (WMD: -0.04; 95% CI: -2.28 to 2.20; P = 0.97); complications (WMD: 1.05; 95% CI: 0.71-1.55; P = 0.82) and pathological details, including lymph nodes harvested (WMD: 0.41, 95% CI: -0.67 to 1.50; P = 0.46), distal resection margin (WMD: -0.35, 95% CI: -1.27 to 0.58; P = 0.46), and positive circumferential resection margin (WMD: 0.54, 95% CI: 0.12-2.39; P = 0.42) were similar between RS and LS. CONCLUSION: RS for rectal cancer is superior to LS in terms of conversion. RS may be an alternative treatment for rectal cancer. Further studies are required.
文摘AIM: To compare the short- and long-term outcomes of laparoscopic and robotic surgery for middle and low rectal cancer.METHODS: This is a retrospective study on a prospectively collected database containing 111 patients who underwent minimally invasive rectal resection with total mesorectal excision (TME) with curative intent between January 2008 and December 2014 (robot, n = 53; laparoscopy, n = 58). The patients all had a diagnosis of middle and low rectal adenocarcinoma with stage I-III disease. The median follow-up period was 37.4 mo. Perioperative results, morbidity a pathological data were evaluated and compared. The 3-year overall survival and disease-free survival rates were calculated and compared.RESULTS: Patients were comparable in terms of preoperative and demographic parameters. The median surgery time was 192 min for laparoscopic TME (L-TME) and 342 min for robotic TME (R-TME) (P < 0.001). There were no differences found in the rates of conversion to open surgery and morbidity. The patients who underwent laparoscopic surgery stayed in the hospital two days longer than the robotic group patients (8 d for L-TME and 6 d for R-TME, P < 0.001). The pathologic evaluation showed a higher number of harvested lymph nodes in the robotic group (18 for R-TME, 11 for L-TME, P < 0.001) and a shorter distal resection margin for laparoscopic patients (1.5 cm for L-TME, 2.5 cm for R-TME, P < 0.001). The three-year overall survival and disease-free survival rates were similar between groups.CONCLUSION: Both L-TME and R-TME achieved acceptable clinical and oncologic outcomes. The robotic technique showed some advantages in rectal surgery that should be validated by further studies.
文摘Throughout the twenty-first century, robotic surgery has been used in multiple oral surgical procedures for the treatment of head and neck tumors and non-malignant diseases. With the assistance of robotic surgical systems, maxillofacial surgery is performed with less blood loss, fewer complications, shorter hospitalization and better cosmetic results than standard open surgery.However, the application of robotic surgery techniques to the treatment of head and neck diseases remains in an experimental stage, and the long-lasting effects on surgical morbidity, oncologic control and quality of life are yet to be established. More well-designed studies are needed before this approach can be recommended as a standard treatment paradigm. Nonetheless,robotic surgical systems will inevitably be extended to maxillofacial surgery. This article reviews the current clinical applications of robotic surgery in the head and neck region and highlights the benefits and limitations of current robotic surgical systems.

文摘AIM: To investigate the incidence of clinically detected port-site metastasis (PSM) in patients who underwent robotic surgery for biliary malignancies. METHODS: Using a prospective database, the patients undergoing fully robotic surgery for biliary malignan- cies between January 2009 and January 2011 were in- cluded. Records of patients with confirmed malignancy were reviewed for clinicopathological data and informa- tion about PSM. RESULTS: Sixty-four patients with biliary tract cancers underwent robotic surgery, and sixty patients met the inclusion criteria. The median age was 67 year (range: 40-85 year). During a median 15-mo follow-up period, two female patients were detected solitary PSM after robotic surgery. The incidence of PSM was 3.3%. Pa- tient 1 underwent robotic anatomatic left hemihepa- tectomy and extraction of biliary tumor thrombi for an Klatskin tumor. She had a subcutaneous mass located at the right lateral abdominal wall near a trocar scar. Patient 2 underwent robotic pancreaticoduodenectomy for distal biliary cancer. She had two metachronous subcutaneous mass situated at the right lateral abdomi- nal wall under a same trocar scar at 7 and 26 mo. The pathology of the excised PSM masses confirmed meta- static biliary adenocarcinoma. CONCLUSION: The incidence of PSIVls after robotic surgery for biliary malignancies is relatively low, and biliary cancer can be an indication of robotic surgery.
