In this context, we highlight minimally invasive mitral valve surgery (MIMVS), which has been shown to be an increasingly solid option with some superior results when compared to the conventional technique: better pain control, shorter hospital stays, shorter recovery time, shorter readmission rate in the first postoperative year, better aesthetic results, and lower overall cost. Aim: This study aims to evaluate the stages of MIMVS, by primary mitral valve consultation, in our service and compare these results with data from the literature. Methods: All electronic medical records of patients who underwent MIMVS for primary mitral valve injury in the Encore Hospital from January 2020 to February 2023 were analyzed. Tabulation and statistical analysis were performed using the Microsoft Excel<sup>®</sup> program. Quantitative variables were presented as means, standard deviations. Results: 46 patients were enrolled in our study (Age: 59.1 ± 12.4 years old;60.8% Female, BMI: 26 ± 4.4 Kg/m<sup>2</sup>, Low risk STS score: 82.6%). The observed 30-day mortality was 2.1%, plastic rate of 23.9%, blood transfusion rate of 41.3%, length of stay in an intensive care bed (ICB) of 3.3 ± 3.3 days and hospital stay of 6.4 ± 5.1 days. Conclusions: We noticed that the MIMVS results carried out in our service agree with data from national and international literature with approximately 1.3 days more hospitalization in ICB.展开更多

Only articles in English journals or published with English language translations were included. Level of evidence of the selected articles was assessed. Statistical data was calculated with analysis of variance with P < 0.05 considered statistically significant.RESULTS: A total of 11 pertinent laminectomy studies, 20 direct lateral studies, and 27 TLIF studies were found. For laminectomy, MIS techniques resulted in a significantly longer length of surgery(177.5 min vs 129.0 min, P = 0.04), shorter LOS(4.3 d vs 5.3 d, P = 0.01) and less perioperative pain(visual analog scale: 16 ± 17 vs 34 ± 31, P = 0.04). There is evidence of decreased narcotic use for MIS patients(postoperative intravenous morphine use: 9.3 mg vs 42.8 mg), however this difference is of unknown significance. Direct lateral approaches have insufficient comparative data to establish relative perioperative outcomes. MIS TLIF had superior EBL(352 mL vs 580 mL, P < 0.0001) and LOS(7.7 d vs 10.4 d, P < 0.0001) and limited data to suggest lower perioperative pain.CONCLUSION: Based on perioperative outcomes data, MIS approach is superior to open approach for TLIF. For laminectomy, MIS and open approaches can be chosen based on surgeon preference. For lateral approaches, there is insufficient evidence to find noninferior perioperative outcomes at this time.展开更多

文摘BACKGROUND Gastric cancer remains a leading cause of cancer-related mortality globally.Traditional open surgery for gastric cancer is often associated with significant morbidity and prolonged recovery.AIM To evaluate the effectiveness of laparoscopic minimally invasive surgery as an alternative to traditional open surgery for gastric cancer,focusing on its potential to reduce trauma,accelerate recovery,and achieve comparable oncological out-comes.METHODS This study retrospectively analyzed 203 patients with gastric cancer who underwent surgery at the Shanghai Health Medical College Affiliated Chongming Hospital from January 2020 to December 2023.The patients were divided into two groups:Minimally invasive surgery group(n=102),who underwent laparoscopic gastrectomy,and open surgery group(n=101),who underwent traditional open gastrectomy.We compared surgical indicators(surgical incision size,intraop-erative blood loss,surgical duration,and number of lymph nodes dissected),recovery parameters(time to first flatus,time to start eating,time to ambulation,and length of hospital stay),immune function(levels of IgA,IgG,and IgM),intestinal barrier function(levels of D-lactic acid and diamine oxidase),and stress response(levels of C-reactive protein,interleukin-6,and procalcitonin).RESULTS The minimally invasive surgery group demonstrated significantly better outcomes in terms of surgical indicators,including smaller incisions,less blood loss,shorter surgery time,and more lymph nodes dissected(P<0.05 for all).Recovery was also faster in the minimally invasive surgery group,with earlier return of bowel function,earlier initiation of diet,quicker mobilization,and shorter hospital stays(P<0.05 for all).Furthermore,patients in the minimally invasive surgery group had better preserved immune function,superior intestinal barrier function,and a less pronounced stress response postoperatively(P<0.05 for all).CONCLUSION Laparoscopic minimally invasive surgery for gastric cancer not only provides superior surgical indicators and faster recovery but also offers advantages in preserving immune function,protecting intestinal barrier function,and mitigating the stress response compared to traditional open surgery.These findings support the broader adoption of laparoscopic techniques in the management of gastric cancer.
文摘BACKGROUND Achilles tendon rupture is a common orthopedic injury,with an annual incidence of 11-37 per 100000 people,significantly impacting daily life.Minimally invasive surgery,increasingly favored for its reduced risks and comparable fixation strength to open surgery,addresses these challenges.Despite advantages like accelerated recovery,perioperative care poses emotional support,pain management,and rehabilitation challenges,impacting treatment efficacy and patient experience.To address these gaps,this study investigated the efficacy of a rapid rehabilitation protocol in enhancing recovery outcomes for minimally invasive Achilles tendon surgery,aiming to develop personalized,standardized care guidelines for broader implementation.AIM To evaluate a nursing-led rapid rehabilitation program for minimally invasive Achilles tendon repair surgery,providing evidence-based early recovery indicators.METHODS This study enrolled 160 patients undergoing channel-assisted minimally invasive Achilles tendon repair randomized into experimental and control groups.The experimental group received perioperative rapid rehabilitation nursing care,while the control group received standard care.The primary outcome measure was the Oswestry disability index score,with secondary outcomes including quality of life,Barthel index,patient satisfaction with nursing,incidence of complications,and rehabilitation adherence.Statistical analysis included appropriate methods to compare outcomes between groups.The study was conducted in a specific setting,utilizing a randomized controlled trial design.RESULTS All 160 patients completed the follow-up.The experimental group showed significantly greater improvements in key efficacy indicators:Postoperative Oswestry disability index score(8.688 vs 18.88,P<0.0001),quality of life score(53.25 vs 38.99,P<0.0001),and Barthel index(70.44 vs 51.63,P<0.0001).The experimental group had a lower incidence of deep vein thrombosis(1.25%vs 10.00%,P=0.0339)with a relative risk of 0.1250(95%confidence interval:0.02050-0.7421).Infection rates were lower in the experimental group(2.50%vs 11.25%,P=0.0564).Hospital stay(5.40 days vs 7.26 days,P<0.0001)and postoperative bed rest(3.34 days vs 5.42 days,P<0.0001)were significantly shorter.Patient satisfaction was 100%in the experimental group vs 87.50%in the control group(P=0.0031).CONCLUSION The rapid rehabilitation intervention significantly reduced pain,shortened hospital stays,and lowered complication rates,improving joint function and patient satisfaction.
文摘BACKGROUND Surgical site infection(SSI)is a common complication of colorectal surgery.Minimally invasive surgery notably reduces the incidence of SSI.This study aimed to compare the incidences of SSI after robot-assisted colorectal surgery(RACS)vs that after laparoscopic assisted colorectal surgery(LACS)and to analyze associated risk factors for SSI in minimally invasive colorectal surgery.AIM To compare the incidences of SSI after RACS and LACS,and to analyze the risk factors associated with SSI after minimally invasive colorectal surgery.METHODS Clinical data derived from patients who underwent minimally invasive colorectal surgery between October 2020 and October 2022 at the First Affiliated Hospital of Soochow University were collated.Differences in clinical characteristics and surgeryrelated information associated with RACS and LACS were compared,and possible risk factors for SSI were identified.RESULTS A total of 246 patients(112 LACS and 134 RACS)were included in the study.Fortythree(17.5%)developed SSI.The proportions of patients who developed SSI were similar in the two groups(17.9%vs 17.2%,P=0.887).Diabetes mellitus,intraoperative blood loss≥100 mL,and incision length were independent risk factors for SSI.Possible additional risk factors included neoadjuvant therapy,lesion site,and operation time.CONCLUSION There was no difference in SSI incidence in the RACS and LACS groups.Diabetes mellitus,intraoperative blood loss≥100 mL,and incision length were independent risk factors for postoperative SSI.
文摘BACKGROUND Ovarian cancer is one of the most common malignant tumors in female reproductive system in the world,and the choice of its treatment is very important for the survival rate and prognosis of patients.Traditional open surgery is the main treatment for ovarian cancer,but it has the disadvantages of big trauma and slow recovery.With the continuous development of minimally invasive technology,minimally invasive laparoscopic surgery under general anesthesia has been gradually applied to the treatment of ovarian cancer because of its advantages of less trauma and quick recovery.However,the efficacy and safety of minimally invasive laparoscopic surgery under general anesthesia in the treatment of ovarian cancer are still controversial.AIM To explore the efficacy and safety of general anesthesia minimally invasive surgery in the treatment of ovarian cancer.METHODS The clinical data of 90 patients with early ovarian cancer in our hospital were analyzed retrospectively.According to the different surgical treatment methods,patients were divided into study group and control group(45 cases in each group).The study group received minimally invasive laparoscopic surgery under general anesthesia for ovarian cancer,while the control group received traditional open surgery for ovarian cancer.The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30),clinical efficacy and safety of the two groups were compared.RESULTS The intraoperative blood loss,length of hospital stay,postoperative gas evacuation time,and postoperative EORTC QLQ-C30 score of the study group were significantly better than those of the control group(P<0.05).The incidence of postoperative complications in the study group was significantly lower than in the control group(P<0.05).The two groups had no significant differences in the preoperative adrenocorticotropic hormone(ACTH),androstenedione(AD),cortisol(Cor),cluster of differentiation 3 positive(CD3+),and cluster of differentiation 4 positive(CD4+)indexes(P>0.05).In contrast,postoperatively,the study group's ACTH,AD,and Cor indexes were lower,and the CD3+and CD4+indexes were higher than those in the control group(P<0.05).CONCLUSION Minimally invasive laparoscopic surgery under general anesthesia in patients with early ovarian cancer can significantly improve the efficacy and safety,improve the short-term prognosis and quality of life of patients,and is worth popularizing.

文摘The management of early stage hepatocellular carcinoma(HCC)presents significant challenges.While radiofrequency ablation(RFA)has shown safety and effectiveness in treating HCC,with lower mortality rates and shorter hospital stays,its high recurrence rate remains a significant impediment.Consequently,achieving improved survival solely through RFA is challenging,particularly in retrospective studies with inherent biases.Ultrasound is commonly used for guiding percutaneous RFA,but its low contrast can lead to missed tumors and the risk of HCC recurrence.To enhance the efficiency of ultrasound-guided percutaneous RFA,various techniques such as artificial ascites and contrast-enhanced ultrasound have been developed to facilitate complete tumor ablation.Minimally invasive surgery(MIS)offers advantages over open surgery and has gained traction in various surgical fields.Recent studies suggest that laparoscopic intraoperative RFA(IORFA)may be more effective than percutaneous RFA in terms of survival for HCC patients unsuitable for surgery,highlighting its significance.Therefore,combining MIS-IORFA with these enhanced percutaneous RFA techniques may hold greater significance for HCC treatment using the MIS-IORFA approach.This article reviews liver resection and RFA in HCC treatment,comparing their merits and proposing a trajectory involving their combination in future therapy.

文摘BACKGROUND Minimally invasive surgery(MIS)and craniotomy(CI)are the current treatments for spontaneous supratentorial cerebral haemorrhage(SSTICH).AIM To compare the efficacy and safety of MIS and CI for the treatment of SSTICH.METHODS Clinical and imaging data of 557 consecutive patients with SSTICH who underwent MIS or CI between January 2017 and December 2022 were retrospectively analysed.The patients were divided into two subgroups:The MIS group and CI group.Propensity score matching was performed to minimise case selection bias.The primary outcome was a dichotomous prognostic(favourable or unfavourable)outcome based on the modified Rankin Scale(mRS)score at 3 months;an mRS score of 0–2 was considered favourable.RESULTS In both conventional statistical and binary logistic regression analyses,the MIS group had a better outcome.The outcome of propensity score matching was unexpected(odds ratio:0.582;95%CI:0.281–1.204;P=0.144),which indicated that,after excluding the interference of each confounder,different surgical modalities were more effective,and there was no significant difference in their prognosis.CONCLUSION Deciding between MIS and CI should be made based on the individual patient,considering the hematoma size,degree of midline shift,cerebral swelling,and preoperative Glasgow Coma Scale score.

文摘BACKGROUND Hypertensive intracerebral hemorrhage is a common critical disease of the nervous system,comprising one fifth of all acute cerebrovascular diseases and has a high disability and mortality rate.It severely affects the patients’quality of life.AIM To analyze the short-term effect and long-term prognosis of neuroendoscopic minimally invasive surgery for hypertensive intracerebral hemorrhage.METHODS From March 2018 to May 2020,118 patients with hypertensive intracerebral hemorrhage were enrolled in our study and divided into a control group and observation group according to the surgical plan.The control group used a hard-channel minimally invasive puncture and drainage procedure.The observation group underwent minimally invasive neuroendoscopic surgery.The changes in the levels of serum P substances(SP),inflammatory factors[tumor necrosis factor-α,interleukin-6(IL-6),IL-10],and the National Hospital Stroke Scale(NIHSS)and Barthel index scores were recorded.Surgery related indicators and prognosis were compared between the two groups.RESULTS The operation time(105.26±28.35)of the observation group was min longer than that of the control group,and the volume of intraoperative bleeding was 45.36±10.17 mL more than that of the control group.The hematoma clearance rates were 88.58%±4.69%and 94.47%±4.02%higher than those of the control group at 48 h and 72 h,respectively.Good prognosis rate(86.44%)was higher in the observation group than in the control group,and complication rate(5.08%)was not significantly different from that of the control group(P>0.05).The SP level and Barthel index score of the two groups increased(P<0.05)and the inflam-matory factors and NIHSS score decreased(P<0.05).The cytokine levels,NIHSS score,and Barthel index score were better in the observation group than in the control group(P<0.05).CONCLUSION Neuroendoscopic minimally invasive surgery is more complicated than hard channel minimally invasive puncture drainage in the treatment of hypertensive intracerebral hemorrhage;however,hematoma clearance is more thorough,and the short-term effect and long-term prognosis are better than hard channel minimally invasive puncture drainage.
文摘The benefits and popularity of minimally invasive surgery are undeniable around the globe.However,open surgery is necessary and learning open surgery skills is still a necessity.Open surgery allows for better exposure to the surgical field and provides tactile sensation to facilitate the stereo visual assessment to precisely remove the lesion.Open surgery is still the key to surgical training,and the skills learned from open surgeries remain crucial for unforeseen circumstances and certain conditions like emergencies,challenge cases,or patients with compromised status.
文摘Transanal minimally invasive surgery(TAMIS)was first described in 2010 as an alternative to transanal endoscopic microsurgery(TEM).The TAMIS technique can be access to the proximal and mid-rectum for resection of benign and earlystage malignant rectal lesions and also used for noncurative intent surgery of more advanced lesions in patients who are not candidates for radical surgery.TAMIS has a shorter learning curve,reduced device setup time,flexibility in instrument use,and versatility in application than TEM.Also,TAMIS shows similar results in a view of the operation time,conversion rate,reoperation rate,and complication to TEM.For these reasons,TAMIS is an easily accessible,technically feasible,and cost-effective alternative to TEM.Overall,TAMIS has enabled the performance of high-quality local excision of rectal lesions by many colorectal surgeons.As TAMIS becomes more broadly utilized such as pelvic abscess drainage,rectal stenosis,and treatment of anastomotic dehiscence,the acquisition of appropriate training must be ensured,and the continued assessment and assurance of outcome must be maintained.

文摘Pancreatic cancer(PC)is the most lethal cancer among digestive system cancers.Although the only way to radically cure PC is surgical resection,complex surgical procedures and severe post-operative complications lead to high mortality.In recent years,minimally invasive surgery has become more common for PC.Minimally invasive pancreatic resection(MIPR)with the laparoscopic or robotic method has shown its superiority compared with traditional surgery.However,increasing evidence indicates that the long-term or even short-term outcomes of MIPR for PC patients remain controversial.Moreover,the indications and learning curve of MIPR require further assessment.This review aims to discuss the progress in current MIPR,analyze the specific problems and obstacles in the development of MIPR,and try to standardize MIPR procedures and improve the outcomes of MIPR.
文摘BACKGROUND Endoscopic submucosal dissection(ESD)can be used for the en-bloc removal of superficial rectal lesions;however,the lack of a traction system makes the procedure long and difficult in the presence of extensive lesions.CASE SUMMARY A large polyp occupying 2/3 of the rectal circumference and extending 5 cm in length was removed by ESD with the help of laparoscopic forceps introduced via trans-anal rectoscopic assisted minimally invasive surgery,a disposable platform designed to aid in transanal minimally invasive surgery.Traction of the polyp by forceps during the operation was dynamic,and applied at various points and in various directions.The polyp was removed en-bloc without complications in 1 h and 55 min.A sigmoidoscopy performed 50 d later showed normal healing without polyp recurrence.CONCLUSION The technique presented here could overcome the issues caused by lack of traction during ESD for rectal lesions.
文摘Introduction: Treatments for cardiovascular diseases have increasingly evolved with the tendency to offer minimally invasive or transcatheter procedures instead of conventional sternotomy surgery. In this context, we highlight minimally invasive mitral valve surgery (MIMVS), which has been shown to be an increasingly solid option with some superior results when compared to the conventional technique: better pain control, shorter hospital stays, shorter recovery time, shorter readmission rate in the first postoperative year, better aesthetic results, and lower overall cost. Aim: This study aims to evaluate the stages of MIMVS, by primary mitral valve consultation, in our service and compare these results with data from the literature. Methods: All electronic medical records of patients who underwent MIMVS for primary mitral valve injury in the Encore Hospital from January 2020 to February 2023 were analyzed. Tabulation and statistical analysis were performed using the Microsoft Excel<sup>®</sup> program. Quantitative variables were presented as means, standard deviations. Results: 46 patients were enrolled in our study (Age: 59.1 ± 12.4 years old;60.8% Female, BMI: 26 ± 4.4 Kg/m<sup>2</sup>, Low risk STS score: 82.6%). The observed 30-day mortality was 2.1%, plastic rate of 23.9%, blood transfusion rate of 41.3%, length of stay in an intensive care bed (ICB) of 3.3 ± 3.3 days and hospital stay of 6.4 ± 5.1 days. Conclusions: We noticed that the MIMVS results carried out in our service agree with data from national and international literature with approximately 1.3 days more hospitalization in ICB.
文摘AIM: To compare minimally invasive(MIS) and open techniques for MIS lumbar laminectomy, direct lateral and transforaminal lumbar interbody fusion(TLIF) surgeries with respect to length of surgery, estimated blood loss(EBL), neurologic complications, perioperative transfusion, postoperative pain, postoperative narcotic use, and length of stay(LOS).METHODS: A systematic review of previously published studies accessible through Pub Med was performed. Only articles in English journals or published with English language translations were included. Level of evidence of the selected articles was assessed. Statistical data was calculated with analysis of variance with P < 0.05 considered statistically significant.RESULTS: A total of 11 pertinent laminectomy studies, 20 direct lateral studies, and 27 TLIF studies were found. For laminectomy, MIS techniques resulted in a significantly longer length of surgery(177.5 min vs 129.0 min, P = 0.04), shorter LOS(4.3 d vs 5.3 d, P = 0.01) and less perioperative pain(visual analog scale: 16 ± 17 vs 34 ± 31, P = 0.04). There is evidence of decreased narcotic use for MIS patients(postoperative intravenous morphine use: 9.3 mg vs 42.8 mg), however this difference is of unknown significance. Direct lateral approaches have insufficient comparative data to establish relative perioperative outcomes. MIS TLIF had superior EBL(352 mL vs 580 mL, P < 0.0001) and LOS(7.7 d vs 10.4 d, P < 0.0001) and limited data to suggest lower perioperative pain.CONCLUSION: Based on perioperative outcomes data, MIS approach is superior to open approach for TLIF. For laminectomy, MIS and open approaches can be chosen based on surgeon preference. For lateral approaches, there is insufficient evidence to find noninferior perioperative outcomes at this time.
文摘Across many of the surgical specialties,the use of minimally invasive techniques that utilize indirect visualization has been increasingly replacing traditional techniques which utilize direct visualization.Arthroscopic surgery of the appendicular skeleton has evolved dramatically and become an integral part of musculoskeletal surgery over the last several decades,allowing surgeons to achieve similar or better outcomes,while reducing cost and recovery time.However,to date,the axial skeleton,with its close proximity to critical neural and vascular structures,has not adopted endoscopic techniques at as rapid of a rate.Over the past decade,increased patient demand for less invasive spine surgery combined with surgeon desire to meet these demands has driven significant evolution and innovation in endoscopic spine surgery.In addition,there has been an enormous advancement in technologies that assist in navigation and automation that help surgeons circumvent limitations of direct visualization inherent to less invasive techniques.There are currently a multitude of endoscopic techniques and approaches that can be utilized in the treatment of spine disorders,many of which are evolving rapidly.Here we present a review of the field of endoscopic spine surgery,including the background,techniques,applications,current trends,and future directions,to help providers gain a better understanding of this growing modality in spine surgery.

文摘In order to restore force sensation to robot-assisted minimally invasive surgery(RMIS),design and performance evaluation of a miniature 6-axis force/torque sensor for force feedback is presented.Based on the resistive sensing method,a flexural-hinged Stewart platform is designed as the flexible structure,and a straightforward optimization method considering the force and sensitivity isotropy of the sensor is proposed to determine geometric parameters which are best suited for the given external loads.The accuracy of this method is preliminarily discussed by finite element methods(FEMs).The sensor prototype is fabricated with the development of the electronic system.Calibration and dynamic loading tests for this sensor prototype are carried out.The working ranges of this sensor prototype are 30 N and 300 N·mm,and resolutions are 0.08 N in radial directions,0.25 N in axial direction,and 2.4 N·mm in rotational directions.It also exhibits a good capability for a typical dynamic force sensing at a frequency close to the normal heart rate of an adult.The sensor is compatible with surgical instruments for force feedback in RMIS.
文摘Restorative low anterior resection(LAR)for rectal cancer carries a significant risk of anastomotic leak:One of the most feared complications in colorectal surgery.Operative management may include takedown of the anastomosis and end colostomy which,in some cases,is permanent.Other contemporary operative measures include over the scope clips and Endosponge.Recently,there have been case reports and a Society of American Endoscopic and Gastrointestinal Surgeons video on the novel use of transanal minimally invasive surgery(TAMIS)in the management of anastomotic leak.We present a 59-year-old female who underwent LAR after declining radiotherapy for a bulky 9 cm rectal tumour 9-10 cm from the anal verge.Following clinical deterioration,computed tomography demonstrated an anastomotic leak communicating with a 5-cm pelvic collection containing gas.At laparoscopy,pus and faeculent material were washed from the pelvic cavity and drains were placed.Intra-operative endoscopy demonstrated a 7-8 mm dehiscence at the anastomosis.The defect(approximately 7 cm from the anal verge)was successfully closed using TAMIS and a running V-lock suture.The patient recovered well and was discharged home on post-operative day 20.In this case,a low colorectal anastomotic leak was successfully rescued with TAMIS.This novel technique may be useful in the armamentarium of colorectal surgeons experienced in TAMIS.
