ObjectiveTo investigate the early clinical efficacy of minimally invasive cardiac surgery coronary artery bypass grafting (MICS CABG) via left intercostal small incision for multivessel coronary artery disease. MethodsThe patients who received off-pump CABG in the Central China Fuwai Hospital of Zhengzhou University from June 2021 to June 2023 were enrolled. Patients were divided into two groups according to the operative technique used, including a traditional midline sternotomy group and a left intercostal small incision group. The clinical data of the two groups were compared. ResultsA total of 143 patients were enrolled, including 70 patients in the traditional midline sternotomy group and 73 patients in the left intercostal small incision group. The age of the patients in the left intercostal small incision group and the traditional midline sternotomy group was (63.8±8.0) years and (63.0±7.8) years, respectively; the proportions of males were 69.9% and 74.3%, respectively. The differences were not statistically significant (all P>0.05). All patients in the two groups successfully completed the operation, and no patients in the left intercostal small incision group were converted to thoracotomy. The patients in the left intercostal small incision group showed less postoperative drainage within postoperative 24 hours [(239.4±177.7) mL vs. (338.0±151.9) mL, P<0.001], lower perioperative blood transfusion rate [32.9% (24/73) vs. 51.4% (36/70), P=0.028], higher postoperative myoglobin level within postoperative 24 hours [366.1 (247.9, 513.0) ng/mL vs. 220.8 (147.2, 314.9) ng/mL, P<0.001], shorter intensive care unit stay [45.5 (31.5, 67.5) h vs. 68.0 (46.0, 78.5) h, P=0.001] and postoperative hospital stay [(10.8±4.0) d vs. (13.1±5.3) d, P=0.028] compared to the traditional midline sternotomy group. There was no significant difference in the incidence of major adverse cardiac and cerebrovascular event between the two groups [2.7% (2/73) vs. 2.9% (2/70), P=1.000]. ConclusionCompared to the full median sternotomy, MICS CABG leads to a good clinical result with smaller trauma, faster overall recovery, and less perioperative blood transfusion.
Radical surgical resection is still the only potentially curative treatment for pancreatic cancer. With the update of minimally invasive concepts, the laparoscopic and robotic platform has been introduced to pancreatic surgery practice. The recent studies have demonstrated that minimally invasive procedure achieved similar or improved perioperative outcomes compared to the standard open approach. Neo-adjuvant chemotherapy is increasingly being applied in pancreatic surgery, making surgical resection more challenging. Numbers of patients undergoing minimally invasive resection following neo-adjuvant chemotherapy remain low. The author consulted the latest literatures at home and abroad and described the current situation of minimally invasive treatment of pancreatic cancer after neo-adjuvant chemotherapy.
Primary palmar hyperhidrosis is a kind of benign disease characterized by abnormally increasing sweat. Various treatments for it exist in clinic currently and the one of them is endoscopic thoracic sympathectomy. But due to the different choice of surgery path, surgery method and the way or the level to block the sympathetic chain, the surgical curative effect and the incidence of postoperative complications vary hugely. This review provides an update report on the surgery method and the way or the level to block the sympathetic chain to treat palmar hyperhidrosis by endoscopic thoracic sympathectomy.
Objective To review the application and research progress of unilateral biportal endoscopy (UBE) technique in the treatment of lumbar related diseases. Methods The domestic and foreign literature on the application of UBE technique in the treatment of lumbar related diseases was extensively consulted, and the development history, clinical application, operation points and precautions, related complications and adverse reactions, advantages and disadvantages of the technique were reviewed. Results As a minimally invasive technique developed in recent years, UBE technique is effective in the treatment of lumbar spinal stenosis caused by different causes, with satisfactory decompression effect, less damage, and good lumbar stability. UBE technique has significant advantages over open surgery and microscopy-assisted surgery in the treatment of lumbar disc herniation. In the treatment of lumbar spondylolisthesis, the postoperative trauma of UBE technique is less than that of conventional surgery, and the fusion rate is satisfactory. There are also complications such as spinal cord injury, spinal epidural hematoma, incomplete decompression or recurrence, nerve root irritation symptoms, and postoperative infection in the treatment of lumbar related diseases with UBE technique. Detailed preoperative planning is essential for patients with lumbar related diseases who are suitable for UBE surgery. Conclusion UBE technique is easy to operate, has a gentle learning curve, can use conventional instruments, and has definite effectiveness. It is suitable for a variety of lumbar related diseases, but there are some defects and deficiencies.
Objective To review the progress in the treatment of acute Achilles tendon rupture. Methods Recent literature about the treatment of acute Achilles tendon rupture was reviewed and analyzed. Results Treatments of acute Achilles tendon rupture include operative and non-operative treatments. Operative treatments include open surgery and percutaneous minimally invasive surgery. Compared with non-operative treatment, operative treatment can effectively reduce the re-rupture incidence, but it had higher complication incidences of wound infection and nerve injury. Although early functional rehabilitation during non-operative treatment could reduce the re-rupture incidence, there is no consistent orthopaedic device and guideline for functional rehabilitation. Conclusion Both operative and non-operative treatments have advantages and disadvantages for the treatment of acute Achilles tendon rupture. No consistent conclusion is arrived regarding functional recovery. Future studies should explore the strategy of early functional rehabilitation during non-operative treatment and its mechanism of promoting tendon healing.
ObjectiveTo investigate the effectiveness of channel-assisted minimally invasive repair system (CAMIR) in treatment of the Myerson types Ⅰ and Ⅱchronic Achilles tendon rupture.MethodsBetween May 2016 and August 2017, 19 patients with Myerson types Ⅰ and Ⅱchronic Achilles tendon ruptures were treated with CAMIR. There were 14 males and 5 females, aged from 21 to 48 years, with an average age of 34.5 years. The disease duration was 5-9 weeks (mean, 7.5 weeks). The preoperative Thompson tests of affected ankles showed positive. There were 11 cases of Myerson type Ⅰwith the gaps of Achilles tendon defect of 1-2 cm (mean, 1.58 cm), and 8 cases of Myerson type Ⅱwith the gaps of Achilles tendon defect of 2.5-4.0 cm (mean, 3.16 cm). The ankle dorsiflexion and plantarflexion range of motion were measured before and after operation; the American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score was used to assess the patients’ ankle joint function.ResultsNo major blood vessels, nerves, and other tissue structures were damaged during the operation; 3 cases of Myerson type Ⅰ were converted to Myerson type Ⅱ according to the gaps of the defect after the scar tissue was removed during the operation. After operation, the depressed part of the Achilles tendon disappeared, the continuity of the tendon was restored, and the Thompson tests were negative. All 19 patients were followed up 12-25 months, with an average of 14 months. All incisions healed by first intention, and no infection and skin necrosis occurred; all the pre-injury activities and exercise were restored at 6 months after operation. During the follow-up period, no heel pain or re-rupture occurred. At last follow-up, except that there was no significant difference in ankle dorsiflexion range of motion of Myerson type Ⅰ patients (t=2.118, P=0.071), the AOFAS ankle and hindfoot score, ankle plantarflexion range of motion of Myerson types Ⅰ and Ⅱ patients, and ankle dorsiflexion range of motion of Myerson type Ⅱ patients were significantly improved when compared with preoperative values (P<0.05). According to AOFAS ankle and hindfoot function score, the ankle joint function of type Ⅰ patients was excellent in 7 cases and good in 1 case, and of type Ⅱ patients were excellent in 8 cases, good in 2 cases, and fair in 1 case.ConclusionCAMIR is safe and effective in the treatment of Myerson types Ⅰ and Ⅱ chronic Achilles tendon rupture with fewer complications and better functional recovery of ankle joint.
ObjectiveTo summarize the experience of minimally invasive anterior mediastinal tumor resection in our center, and compare the Da Vinci robotic and video-assisted thoracoscopic approaches in the treatment of mediastinal tumor.MethodsA retrospective cohort study was conducted to continuously enroll 102 patients who underwent minimally invasive mediastinal tumor resection between September 2014 and November 2019 by the single medical group in our department. They were divided into two groups: a robotic group (n=47, 23 males and 24 females, average age of 52 years) and a thoracoscopic group (n=55, 29 males and 26 females, average age of 53 years). The operation time, intraoperative blood loss, postoperative thoracic drainage volume, postoperative thoracic drainage time, postoperative hospital stay, hospitalization expense and other clinical data of two groups were compared and analyzed.ResultsAll the patients successfully completed the surgery and recovered from hospital, with no perioperative death. Myasthenia gravis occurred in 4 patients of the robotic group and 5 of the thoracoscopic group. The tumor size was 2.5 (0.8-8.7) cm in the robotic group and 3.0 (0.8-7.7) cm in the thoracoscopic group. Operation time was 62 (30-132) min in the robotic group and 60 (29-118) min in the thoracoscopic group. Intraoperative bleeding volume was 20 (2-50) mL in the robotic group and 20 (5-100) mL in the thoracoscopic group. The postoperative drainage volume was 240 (20-14 130) mL in the robotic group and 295 (20-1 070) mL in the thoracoscopic group. The postoperative drainage time was 2 (1-15) days in the robotic group and 2 (1-5) days in the thoracoscopic group. There was no significant difference between the two groups in the above parameters and postoperative complications (P>0.05). The postoperative hospital stay were 3 (2-18) days in the robotic group and 4 (2-14) in the thoracoscopic group (P=0.014). The hospitalization cost was 67 489(26 486-89 570) yuan in the robotic group and 27 917 (16 817-67 603) yuan in the thoracoscopic group (P=0.000).ConclusionCompared with the video-assisted thoracoscopic surgery, Da Vinci robot-assisted surgery owns the same efficacy and safety in the treatment of mediastinal tumor, with shorter postoperative hospital stay, but higher cost.
ObjectiveTo investigate the therapeutic effect, safety and effectiveness of multiple valvular surgery through right anterolateral intercostal thoracotomy, as well as the mid-term follow-up results and surgeon's learning curve.MethodsThe clinical data of 154 patients with multiple valvular disease were performed minimally invasive cardiac surgery in the Department of Cardiovascular Surgery, The First Affiliated Hospital of Air Force Medical University, from 2015 to 2019 were retrospectively analyzed. There were 103 males and 51 females, aged 23-68 years. Closed cardiopulmonary bypass was established through femoral artery and femoral vein, and the thoracic cavity was entered through a 6 cm transverse incision in the fourth intercostal space on the right side of sternum. Baseline and perioperative characteristics and postoperative outcomes were reviewed.ResultsThere was no perioperative death. The average cardiopulmonary bypass time was 159.3±39.4 min, and the aortic clamping time was 102.3±20.3 min. One patient underwent thoracotomy during the operation, and two patients underwent second thoracotomy for hemostasis. During the follow-up period of 10-55 months, 1 patient died, 2 patients developed mild perivalvular regurgitation, 6 patients developed moderate tricuspid regurgitation, and no serious cardiovascular events occurred in the rest of the patients.ConclusionOur findings demonstrate that multiple valvular surgery through right anterolateral intercostal thoracotomy is safe, and in an acceptable risk of complication. The early and middle follow-up results are satisfactory. The minimally invasive cardiac surgery can also meet the requirements of cosmetology, and is conducive to the recovery of patients' mental and physical health. This method is worthy of application in medical centers with rich experience in routine cardiac surgery.
ObjectiveTo investigate the effectiveness and safety of totally endoscopic transmitral myectomy (TETM) for hypertrophic obstructive cardiomyopathy (HOCM), comparing with traditional sternotomy modified Morrow procedure (SMMP).MethodsThirty-eight patients with HOCM who needed surgical intervention were selected from our hospital in 2019, including 14 males and 24 females, with an average age of 56 (44-68) years. According to the operation method, they were divided into a TETM group (n=18) and a SMMP group (n=20). Appropriate patients were screened by propensity matching scores. Finally, the clinical data of two matched groups were compared and analyzed.ResultsThere was no death, septal perforation, residual left ventricular outflow tract obstruction or third degree atrioventricular block in either group. After propensity score matching, there was no statistical difference between the two groups in the ICU length of stay (41.5±5.0 h vs. 53.0±24.0 h, P=0.620), ventilation time (19.5±9.2 h vs. 38.0±24.0 h, P=0.463), cardiopulmonary bypass time (190.7±45.6 min vs. 156.0±70.7 min, P=0.627), aortic cross-clamp time (100.1±25.3 min vs. 94.5±57.3 min, P =0.915), left ventricular outflow tract gradient (17.0±1.4 mm Hg vs. 5.0±0.5 mm Hg, P=0.053), left atrial anterior and posterior diameter (37.0±1.3 mm vs. 40.0±0.7 mm, P=0.090), interventricular septum thickness (12.5±0.7 mm vs. 13.0±1.4 mm, P=0.712), left ventricular posterior wall thickness (10.0±1.4 mm vs. 10.5±2.1 mm, P=0.811), left ventricular end-diastolic diameter (43.5±3.5 mm vs. 46.0±4.2 mm, P=0.589), and mitral regurgitation (1.0±0.2 vs. 0.7±0.5, P=0.500). The follow-up time was 6±3 months, and no death occurred. In the TETM group, one patient underwent mitral valvuloplasty again three months after surgery because of a tear in the A3 region of mitral valve..ConclusionTETM is a safe and effective procedure that can well expose the interventricular septum at the basal & middle obstruction site and effectively eliminate the mitral regurgitation associated with systolic anterior motion syndrome caused by left ventricular outflow tract obstruction.
ObjectiveTo analyze the feasibility and effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound.MethodsThe clinical data of 30 patients with the fifth metacarpal neck fractures who were treated with elastic intramedullary nails fixation under the guidance of high frequency ultrasound and met the selection criteria between May 2013 and September 2017 were retrospectively analysed. There were 24 males and 6 females, the age ranged from 18 to 58 years, with an average of 31.4 years. The head-shaft angle of the fifth metacarpal was (55.6±11.3)°. The time from injury to operation was 12 hours to 8 days, with an average of 2.4 days. The operation time, number of intraoperative fluoroscopy, fracture reduction, complications, and fracture healing time were recorded. The head-shaft angle of the fifth metacarpal on the affected side after fracture healing were measured and compared with the healthy side. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint of both sides were measured, and the function was evaluated by using the total active movement (TAM) evaluation standard of the Hand Surgery Association of Chinese Medical Association.ResultsThe operation time was 22-40 minutes, with an average of 32.4 minutes; the intraoperative fluoroscopy was performed once; ultrasound images and X-ray fluoroscopy showed that the fracture was well reduced and no adjustment was required. The incisions healed well after operation, without tendon adhesion or local numbness. All 30 patients were followed up 8-16 months, with an average of 11.7 months. The fracture healing time was 4-8 weeks, with an average of 5.6 weeks. The head-shaft angle of the fifth metacarpal was (13.2±1.4)°, which was significantly improved when compared with preoperative value (t=−20.02, P=0.00); and there was no significant difference (t=1.94, P=0.06) when compared with the healthy side [(12.6±1.0)°]. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint on the affected side was (89.4±2.4)°, showing no significant difference (t=−1.58, P=0.13) when compared with the healthy side [(90.3±2.0)°]. According to the TAM evaluation standard of the Hand Surgery Association of Chinese Medical Association, all patients were considered to be excellent.ConclusionThe effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound is definite. It can dynamically observe the fracture reduction from different angles, reduce ionizing radiation and postoperative complications.
