Objective To investigate the clinical efficacy of minimally invasive mitral valvuloplasty (MVP) in the treatment of infective endocarditis (IE) with mitral regurgitation (MR). Methods A retrospective analysis was conducted on the clinical data of patients who underwent MVP for IE with MR at the Department of Cardiovascular Surgery in Zhongshan Hospital, Fudan University from 2016 to 2020. Patients were divided into two groups based on the surgical incision: those with a right mini-thoracotomy were classified as a minimally invasive surgery (MIS) group, and those with a median sternotomy (MS) were classified as an MS group. All patients had isolated mitral valve involvement. Perioperative data were analyzed, and mid- to long-term outcomes were compared between the two groups. Results A total of 86 patients were included, with 40 in the MIS group [22 males and 18 females, with a mean age of (39.78±15.36) years ranging from 14 to 75 years] and 46 in the MS group [27 males and 19 females, with a mean age of (49.94±16.13) years ranging from 14 to 71 years]. The patients in the MIS group were relatively younger (P=0.004) with better preoperative cardiac function (P=0.004). There was no statistical difference in preoperative fever, gender, or comorbidities between the two groups (P>0.05). The MIS group had shorter postoperative ventilation times, less postoperative 24-hour drainage, less blood transfusion, and shorter total hospital stays compared to the MS group (P<0.05). There was no statistical difference in cardiopulmonary bypass times or ICU stays between the two groups (P>0.05). The perioperative complication rates and mortality rates were not significantly different between the two groups (P>0.05). Follow-up was conducted for 11-92 months, with a mean duration of (49±19) months and an overall follow-up rate of 91.9%. During the follow-up, 3 patients in each group required reoperation for mitral valve issues, with no statistical difference in incidence (7.5% vs. 6.5%, P=0.691). There were no warfarin-related complications, recurrences, or deaths in either group during follow-up. Multivariate regression analysis identified age, preoperative cardiac function, and surgeon experience as influencing factors for the choice of surgical approach. Conclusion Minimally invasive MVP for IE with MR is relatively safe in the perioperative period and shows significant efficacy, with clear mid- to long-term outcomes. It is recommended for younger patients with better preoperative cardiac function and when performed by surgeons with extensive experience in mitral valvuloplasty.

Nasojejunal feeding tubes are widely used in surgical,intensive care,and older patients.Manual blind insertion of nasojejunal feeding tubes is technically challenging,associated with a high failure rate,and prone to complications.The primary causes of suboptimal placement outcomes are the uncertainty and weak controllability of the interaction forces during the coordination between manual posterior advancement and the patient's physiological state.While current auxiliary techniques such as X-ray,ultrasound,and endoscopy can improve the success rate of nasojejunal tube placement and reduce complications to some extent,the accuracy and safety of placement remain constrained by challenges in controlling insertion forces and achieving precise positional localization.Robotic technology holds promise for addressing the uncertainties and controllability issues inherent in the placement process.By leveraging precise sensing,real-time navigation,and efficient control,robots can achieve intelligent positioning and precise control over the direction and location of the catheter tip during nasojejunal intubation.However,current research on robotic applications for nasojejunal feeding tube placement is still in an early stage,facing challenges such as high costs,operational complexity,and concerns over safety and reliability.Herein,we analyzed the limitations and causes of failure in existing placement methods and explored the application prospects of robotic technologies for precise control and intelligent positioning in nasojejunal feeding tube placement.The paper provides new insights for developing nursing techniques that enable safer and more effective,comfortable,and rapid intubation.Future efforts should focus on deepening the integration of artificial intelligence and robotics,optimizing drive technologies,and accelerating the translation of these technologies from the laboratory to clinical practice.This will drive the advancement of nasojejunal feeding tube placement techniques towards intelligent,precise,and accessible solutions.

Objective To compare the outcome of combined and staged approach on concomitant carotid and coronary severe stenosis.Methods From March 2013 to May 2015,27 patients with concomitant carotid and coronary severe stenosis were treated by carotid endarterectomy and coronary artery bypass grafting,15 cases received one-stage operation and 12 staged.The basic characteristics,details during surgery,complications,quality of life score,hospital stay and cost were compared.Results 27 patients received carotid endarterectomy and off-pump coronary artery bypass grafting under general anesthesia.Revascularization were performed on 27 carotid and 82 coronary artery.The characteristics of patients were similar between two groups,reflected with WIC,combined approach subgroup was (5.27 ± 0.88) and staged subgroup was (4.92 ± 1.24).The operation time was significantly decreased in the synchronous group [(295.33 ± 49.73)min vs (390.83 ± 73.45) min,P < 0.001].Hospital stay days was also reduced [(30.20 ± 12.91) days vs(44.67 ± 6.34) days,P =0.002],the medical cost was lower in combined approach group,but no significant statistical difference.The complications including 1 case TIA,1 recurrent nerve injury in one-stage group and 1 case myocardial infarction,1 mediastinal bleeding post-operation and 1 pulmonary infection in stage group.No cerebral infarction and death.Quality of life scores(SF-36) of the two groups was 5.53 ± 1.30 and 5.75 ± 1.36 respectively,no significant difference.Conclusion The efficacy and safety of treatment for concomitant carotid and coronary severe stenosis patients with combined or staged approach was similar.But the combined approach program can reduce the hospital stay time and cost in some degree.

Objective To study the clinical outcome of endoscopic vessel harvesting system (EVH) for the treatment of lower limbs varicose veins.Methods Patients (n =41) with varicose veins admitted from Jan 2011 to May 2013 were randomly divided into EVH group (n =20) and stripping group (n =21).Indexes as postoperative VAPS (48 hours and 1 week),subcutaneous ecchymosis (1 week),hematoma(1 week),skin numbness (1 week),CEAP classification (3 months),surgery effect and satisfaction scores(3 months) were compared between the two groups.Results 48 hours and 1 week VAPS was lower in EVH group(P <0.01).After EVH there was less subcutaneous ecchymosis (1 week),hematoma(1 week) and skin numbness (1 week) (all P < 0.01).Postoperative CEAP classification improved significantly in both groups (P < 0.01),while surgery effect and satisfaction scores (3 months) were better in EVH group (P < 0.05).Conclusions EVH is a safe and minimally invasive technique in treatment of varicose veins of the lower limbs.
