Surgical treatment is an important treatment for spontaneous pneumothorax, which can remove the gas in the pleural cavity, relieve symptoms, promote lung recruitment, moreover, prevent future recurrence. The surgical modalities included video-assisted thoracoscopic surgery (VATS) and non VATS treatment. Nowadays, the treatment of spontaneous pneumothorax has entered a minimally invasive era. With the development of minimally invasive techniques in recent years, as the representative of minimally invasive surgery, the surgeon techniques of VATS has developed to diversity, including three-port VATS, two-port VATS, uniportal VATS, subxiphoid uniportal VATS, 3D VATS, robotic-assisted VAT and cervical uniportal VATS. Each technique has its own advantages and limitations, and individual choices should be made.
Objective To investigate the role of cardiac rehabilitation program in the early recovery after minimally invasive incision coronary artery bypass grafting with general anesthesia. MethodsA retrospective study was performed on the patients who underwent minimally invasive incision coronary artery bypass grafting from January 2015 to January 2020 with general anesthesia in our hospital. The patients were divided into a cardiac rehabilitation group and a control group. The clinical data of the patients were collected in 6 months and 12 months after the beginning of cardiac rehabilitation program and were analyzed by propensity score-matching analysis with a ratio of 1∶1. The main outcomes were the peak oxygen uptake (VO2 peak) of cardiopulmonary function test and the number of patients attending cardiovascular specialties in tertiary hospitals during the follow-up period (20 months). ResultsA total of 600 patients were enrolled, including 200 patients in the cardiac rehabilitation group [137 males and 63 females, aged 61.00 (56.00, 65.00) years] and 400 patients in the control group [285 males and 115 females, aged 60.00 (56.00, 65.00) years]. After matching, 176 patients were included in each group, and the basical clinical data of the pateints were comparable (P>0.05). The VO2 peak of the cardiac rehabilitation group after 6 months and 12 months of cardiac rehabilitation was significantly different from that of the control group [6 months: 1.96 (1.59, 2.38) L/min vs. 1.72 (1.38, 2.12) L/min, P<0.001; 12 months: 2.40 (2.21, 2.63) L/min vs. 2.12 (1.83, 2.45) L/min, P<0.001]. During the follow-up period, there was a statistical difference in the cardiovascular specialist visits in tertiary hospitals (P=0.004). ConclusionCardiac rehabilitation program has a positive effect on the recovery of minimally invasive incision coronary artery bypass grafting with general anesthesia, and can improve the exercise ability of patients.
ObjectiveTo compare the effectiveness of lateral approach minimally invasive plate osteosynthesis (MIPO) and helical plate MIPO in the treatment of proximal humeral shaft fractures. Methods The clinical data of patients with proximal humeral shaft fractures who underwent MIPO via lateral approach (group A, 25 cases) and MIPO with helical plate (group B, 30 cases) between December 2009 and April 2021 were retrospectively analyzed. There was no significant difference in gender, age, injured side, cause of injury, American Orthopaedic Trauma Association (OTA) fracture classification, and time from fracture to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, and complications were compared between two groups. The angular deformity and the fracture healing were evaluated according to anteroposterior and lateral X-ray films postoperatively. The modified University of California Los Angeles (UCLA) score for shoulder and the Mayo Elbow Performance (MEP) score for elbow were analyzed at last follow-up. Results The operation time in group A was significantly shorter than that in group B (P<0.05). However, the intraoperative blood loss and fluoroscopy times presented no significant difference between the two groups (P>0.05). All patients were followed up 12-90 months, with an average of 19.4 months. There was no significant difference in follow-up time between the two groups (P>0.05). In terms of the quality of postoperative fracture reduction, there were 4 (16.0%) and 11 (36.7%) patients with angulation deformity in group A and group B, respectively, and there was no significant difference in the incidence of angulation deformity (χ2=2.936, P=0.087). All fractures achieved bony union, there was no significant difference in fracture healing time between group A and group B (P>0.05); delayed union occurred in 2 cases and 1 case in group A and group B, respectively (healing time was 30, 42, and 36 weeks after operation, respectively). In group A and group B, 1 patient had superficial infection of incision, respectively; 2 patients and 1 patient had subacromial impact after operation, respectively; and 3 patients in group A had symptoms of radial nerve paralysis of different degrees; all of them were cured after symptomatic treatment. The overall complication incidence of group A (32%) was significantly higher than that of group B (10%) (χ2=4.125, P=0.042). At last follow-up, there was no significant difference in the modified UCLA score and MEPs score between the two groups (P>0.05). Conclusion Both lateral approach MIPO and helical plate MIPO can achieve satisfied effectiveness in the treatment of proximal humeral shaft fractures. Lateral approach MIPO may be beneficial to shorten the operation time, while the overall complication incidence of helical plate MIPO is lower.
ObjectiveTo compare the surgical efficacy of Da Vinci robot-assisted minimally invasive esophagectomy (RAMIE) and video-assisted minimally invasive esophagectomy (VAMIE) on esophageal cancer.MethodsOnline databases including PubMed, the Cochrane Library, Medline, EMbase and CNKI from inception to 31, December 2019 were searched by two researchers independently to collect the literature comparing the clinical efficacy of RAMIE and VAMIE on esophageal cancer. Newcastle-Ottawa Scale was used to assess quality of the literature. The meta-analysis was performed by RevMan 5.3.ResultsA total of 14 studies with 1 160 patients were enrolled in the final study, and 12 studies were of high quality. RAMIE did not significantly prolong total operative time (P=0.20). No statistical difference was observed in the thoracic surgical time through the McKeown surgical approach (MD=3.35, 95%CI –3.93 to 10.62, P=0.37) or in surgical blood loss between RAMIE and VAMIE (MD=–9.48, 95%CI –27.91 to 8.95, P=0.31). While the RAMIE could dissect more lymph nodes in total and more lymph nodes along the left recurrent laryngeal recurrent nerve (MD=2.24, 95%CI 1.09 to 3.39, P=0.000 1; MD=0.89, 95%CI 0.13 to 1.65, P=0.02) and had a lower incidence of vocal cord paralysis (RR=0.70, 95%CI 0.53 to 0.92, P=0.009).ConclusionThere is no statistical difference observed between RAMIE and VAMIE in surgical time and blood loss. RAMIE can harvest more lymph nodes than VAMIE, especially left laryngeal nerve lymph nodes. RAMIE shows a better performance in reducing the left laryngeal nerve injury and a lower rate of vocal cord paralysis compared with VAMIE.
Objective To review the research progress related to endoscopic surgery and robotic surgery for breast diseases, aiming to provide references for clinical practice. Methods The recent domestic and international literature on endoscopic surgery and robotic surgery for breast diseases was reviewed, then the challenges in their development, the innovative evolution of endoscopic surgery combined with clinical practice by our team, and its clinical applications were summarized. ResultsTraditional endoscopic surgery, despite its advantages such as minimal invasiveness, good cosmetic outcomes, and high patient’s satisfaction, has been limited in its development due to specific difficulties in establishing the operative field. Our team innovatively proposed the “reverse sequence method” and the Huaxi Hole 1 theory and methods, cleverly altering the surgical procedure sequence, adding small operative orifices to transform single-port operations into multi-port ones, effectively overcoming the challenges restricting the advancement of endoscopic surgery in the field of breast diseases, thereby enabling further proliferation of endoscopic procedures. In terms of breast endoscopic reconstruction surgery, the parachute patch technique has broadened the indications for reconstruction surgery, benefiting patients with a certain degree of breast ptosis; and the postoperative adjustment concept, through early intervention in the post-reconstruction breast shape, has further refined the reconstruction procedure. Robot-assisted surgery derived from endoscopic surgery theory has further enhanced the precision and stability of surgeries, reducing surgical risks; however, excessive time and economic costs are urgent issues that must be addressed. Conclusion Through theoretical innovations, endoscopic surgery has been applied in the excision and reconstruction of breast lesions, while robotic surgery shows promising applications in autologous breast reconstruction, especially in the latissimus dorsi reconstruction field. Nevertheless, the lack of high-level large-sample, multi-center randomized controlled clinical trials to confirm its surgical safety, oncological safety, and postoperative cosmetic outcomes is an important direction for future research.
Objective To summarize the research progression of video-assisted anal fistula treatment (VAAFT). Methods The related literatures in recent years were reviewed, and then the operation principle, operation process, advantages and disadvantages, matters needing attention, and clinical application of VAAFT were summarized. Results VAAFT is the treatment of fistulas by endoscopy. It don’t require the incision or resection of the fistula. It has the advantages of less surgical trauma, faster postoperative recovery, and less impact on the anal sphincter. The disadvantage of this method is relatively strict indications, fistula bending or horseshoe fistula is not suitable for this method. In addition, the endoscope using during the operation is a rigid mirror tube, and the operation is not convenient enough, so technical improvement is needed in the future. We should pay attention to distinguish true fistula and false fistula in clinical practice; the wall of the fistula should be adequately burned and the necrotic tissue should be cleaned; the treatment of the internal opening of anal fistula must be exact; the time of the first defecation should be appropriately delayed, and the incidence of infection should be reduced after operation. At present, the clinical reports of VAAFT are increasing gradually in foreign countries, and these reports have achieved good therapeutic effect. It is considered that this method maybe a safe and effective minimally invasive surgical treatment for anal fistula. However, there is few clinical reports on VAAFT in China, and it is still in the preliminary stage of exploration. Conclusion VAAFT is a new technology in the treatment of anal fistula, and it has advantages of minimally invasive, sphincter preservation, and so on, which is worthy of clinical application.
Objective To explore the technique of performing minimally invasive Cox Maze Ⅳ procedure by bipolar clamp through right lateral minithoracotomy for atrial septal defect (ASD) combined with atrial fibrillation (AF) in adults. Methods Thirty-five patients (21 males, 14 females with age ranging from 45 to 73 years) with ASD and persistent or long-standing persistent AF received minimally invasive Cox Maze Ⅳ procedure and ASD closure from August 2012 to April 2016 at Department of Cardiothoracic Surgery, Xinhua Hospital. Diameter of left atrium ranged from 39 to 60 mm and left ventricle ejection fraction (LVEF) ranged from 48% to 62%. Diameter of ASD ranged from 20 to 35 mm. Cox-maze Ⅳ procedure was performed through right minithoracotomy entirely by bipolar radiofrequency clamp. Then, mitral or tricuspid valvuloplasty and surgical ASD closure was performed through right minithoracotomy. Results All patients successfully underwent this minimally invasive surgery. No patient needed conversion to sternotomy. The mean cardiopulmonary bypass time was 120.1±14.1 min. The mean aortic cross-clamp time was 79.5±12.2 min. There was no early death or pacemaker implantation perioperatively. The average length of hospital stay was 10.1±2.7 d. At a mean follow-up of 22.8±12.2 months, sinus rhythm was restored in 32 patients (32/35, 91.4%). Cumulative maintenance of normal sinus rhythm without AF recurrence at 2 years postoperatively was 89.1%±6.0%. Conclusion The minimally invasive Cox Maze Ⅳprocedure performed by bipolar clamp through right minithoracotomy is safe, feasible, and effective for adult patients with ASD combined with AF.
ObjectiveTo investigate the effectiveness of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach in treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures. Methods A clinical data of 46 patients with Sanders type Ⅱand Ⅲ calcaneal fractures met the selective criteria between March 2016 and March 2021 was retrospectively analyzed. The factures were fixed with minimally invasive plate and medial supporting cannulated screws via tarsal sinus approach in 20 cases (group A) and with minimally invasive plate in 26 cases (group B). There was no significant difference between groups in term of the gender, age, injury causes, fracture type and side, the time from injury to operation, and preoperative calcaneal length and width, Böhler angle, Gissane angle, and visual analogue scale (VAS) score (P>0.05). The operation time, intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing were recorded. The pain improvement of patients was evaluated by VAS scores before operation and at 48 hours after operation. The ankle joint function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score at 3 and 12 months after operation. Besides, the calcaneal length and width, Böhler angle, and Gissane angle were measured by X-ray films before and after operation. Furthermore, the difference (loss value) between 3, 12 months and 1 day after operation was calculated. Moreover, the fracture healing and healing time was observed. ResultsAll operations of two groups were successfully completed. The incisions healed by first intention, and no vascular/nerve injury or incision infection occurred. The operation time of group A was significantly longer than that of group B (P<0.05). There was no significant difference in the intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing (P>0.05). All patients were followed up 12-36 months (mean, 14.8 months). The VAS scores at 48 hours after operation were significantly lower than those before operation in the two groups (P<0.05); there was no significant difference in the difference of pre- and post-operative VAS score between groups (P>0.05). The AOFAS scores at 12 months after operation were significantly higher than those at 3 months after operation in the two groups (P<0.05); and there was no significant difference between groups at 3 and 12 months (P>0.05). X-ray films showed that the fractures of the two groups healed and there was no significant difference in healing time (P>0.05). There was no significant difference in calcaneal length and width and Gissane angle between groups at each time point (P>0.05), but there was significant difference in Böhler angle between groups at 12 months (P<0.05). The imaging indexes of the two groups significantly improved at each time point after operation when compared with those before operation (P<0.05). There was no significant difference between different time points after operation (P>0.05) in the imaging indexes of group A. There were significant differences in the calcaneal length, calcaneal width, and Gissane angle of group B between 12 months and 1 day, 3 months after operation (P<0.05), and there was no significant difference between 1 day and 3 months after operation (P>0.05). The differences in Böhler angle of group B between different time points after operation were significant (P<0.05). There was no significant difference between groups in the loss of all imaging indexes at 3 months after operation (P>0.05). The losses of calcaneal width, Böhler angle, and Gissane angle in group A at 12 months after operation were significantly smaller than those in group B (P<0.05), and there was no significant difference in the loss of calcaneus length between groups (P>0.05). ConclusionCompared with only minimally invasive plate fixation, the combination of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach for Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of less trauma, less incision complications, reliable fracture reduction and fixation, and good long-term stability.
ObjectiveTo summarize the treatment results of double aortic arch (DAA) by minimally invasive surgical technique. MethodsWe retrospectively analyzed the clinical data of DAA patients who underwent minimally invasive surgeries in our center between October 2016 and August 2021. ResultsThere were 11 males and 4 females with a mean age of 3-61 (20.00±18.80) years. There were 8 patients of DAA and 7 patients of DAA complicated with distal left-sided aortic arch atresia and ligamentum connection. All patients received operations through minimal subaxillary incision, 13 patients were through left side and 2 patients were through right side. One patient with ventricular septal defect was performed operations concurrently under the cardiopulmonary bypass through right minimal subaxillary incision. All patients had symptom improvement without surgery related complications or death in postoperative period. The duration of operation was 30-192 (61.93±40.19) min and mechanical ventilation time was 2-9 (5.33±2.53) h. The length of ICU stay was 18-124 (51.00±38.07) h and hospital stay time was 8-21 (12.67±3.42) d. All patients had symptomatic relief with good growth and exercise tolerance during the follow-up of 6 (3, 9) months. ConclusionMinimally invasive surgical technique is a safe, effective and cosmetic approach with good results for DAA treatment.
ObjectiveTo evaluate the early effectiveness of the robot-assisted total hip arthroplasty (THA) via direct superior approach (DSA).MethodsBetween March 2021 and April 2021, 11 patients (11 hips) were treated with a robot-assisted THA via DSA. There were 7 males and 4 females, with an average age of 55 years (range, 26-73 years). There were 5 patients of osteoarthritis secondary to hip dysplasia and 6 patients of osteonecrosis of femoral head. Preoperative hip Harris score was 55.8±6.3. The operation time, volume of blood loss, length of incision, postoperative blood transfusion and hospital stay, and the incidence of surgical complications were recorded. The visual analogue scale (VAS) score and Harris score were used to evaluate hip joint pain and function. The leg length discrepancy (LLD) was measured on the X-ray films. The inclination angle and anteversion angle of the acetabular component were also measured, and the difference between the planned and actual values were compared.ResultsOne THA was performed via conventional posterolateral approach finally because of poor exposure. The rest of 10 THAs were performed with assistance of robotic arm via DSA. The average operation time was 89 minutes (range, 65-120 minutes); the average length of incision was 10.5 cm (range, 9-13 cm); and the average blood loss was 400 mL (range, 110-740 mL). One patient was given a blood transfusion for 2 unit. All incisions healed by first intention and no neurovascular injury, deep vein thrombosis, or fracture occurred. The length of hospital stay after operation was 2-6 days (mean, 4.4 days). The duration of follow-up was 1-3 months (mean, 2.1 months). The VAS score was 0 in 9 patients and 2 in 1 patient at the day of discharge. At last follow-up, the hip Harris score was 84.9±6.7, showing significant difference when compared with that before operation (t=−8.717, P=0.000). The inclination and anteversion angles were (37.4±2.0)° and (17.1±4.5)°, respectively, and there was no significant difference when compared with the planned values [(38.2±1.6)°, (16.6±3.7)°] (t=1.809, P=0.104; t=–1.103, P=0.299). The LLD ranged from –2 to 4 mm. No complication such as dislocation, aseptic loosening, or periprosthetic joint infection occurred. ConclusionThe robot-assisted THA via DSA has encouraged early effectiveness.
