Objective:To assess the feasibility and safety of 2-staged hybrid technique for treating coronary artery disease (CAD) patients with multi-vessel lesions.
Methods: Our research included 2 groups:Hybrid group, CAD patients with left anterior descending artery (LAD) lesion or with other major epicardial vessel stenosis>70%who received 2-staged hybrid treatment in our hospital from 2012-03 to 2015-03 and Control group, CAD patients received elective conventional off-pump coronary artery bypass (OPCAB) by the same surgeon at meanwhile. n=91 in each group. The peri-operative conditions and complications were compared between two groups.
Results: Compared with Control group, Hybrid group had the shorter post-operative mechanical ventilation time (7.9 ± 4.8) h vs (21.6 ± 35.9) h, shorter ICU-stay time (29.6 ± 20.8) h vs (47.5 ± 38.3) h, all P<0.01 and less peri-operative blood transfusion (0.59 ± 1.48) U vs (2.82 ± 3.81) U, P<0.01. The post-operative complications of mortality, MI occurrence and delayed wound healing were similar between 2 groups, P>0.05.
Conclusion:2-staged hybrid technique is a safe, feasible and minimally invasive technique for treating CAD patients with LAD and multi-vessel lesions.

Objective To explore the situation and question of standardized training of residents/graduate students in cardiac surgery by questionnaire survey. Methods From September 2010 to May 2012, 61 resident physicians/graduate students were chosen as research objects in Department of Cardiac Surgery, Peking University Third Hospital. A total of 61 questionnaires were sent out, with a recovery rate of 100%,and an effective rate of 95.1%.The contents of investigation included standardized training content design, standardized training management, the time and"environment" pressure, compliance training effect analysis,student opinion and others,a total of 14 options.EpiData 2.1a software was used to sort and record the data. SPSS 17.0 software was used for statistical analysis. The enumeration data were compared by chi square test.Results During the period of training,the most expected teaching method was"small lecture", accounting for 63.8%; The most difficult part of the process of cardiac surgery training was "postoperative care", accounting for 69%; 100% of the trainees thought that it would be helpful for future work through cardiac training;8.3% of the trainees thought the teachers of cardiac surgery teaching consciousness was not strong; resident weekend "in the hospital" was higher than the proportion of graduate students, and most graduate students chose weekend "in the experiment and research work", the difference was statistically significant (P<0.05). Conclusion Appropriate standardized training program should be combined with the students' background; Teaching team construction and clinical reasonable and effective clinical skills train-ing system is an important link to ensure the quality of teaching.The combination of residents' standardized training and postgraduate education of professional degree remains to be tracked and evaluated in a long time.The feedback from all aspects of the training should be paid more attention to,and the training details should be improved.

Objective To analyze the feasibility of using triangular-sail technique that allows intermittent two-lung ventilation during minimally invasive coronary artery bypass grafting (MICS CABG). Methods The clinical data of 207 patients with MICS CABG in our cardiac center from January 2019 to November 2020 were retrospectively analyzed. These patients were divided into two groups. A group OLV included 111 patients who underwent one-lung ventilation during surgery, while a group TLV included 96 patients who underwent intermittent two-lung ventilation. The triangular-sail technique was used in the group TLV. This simple technique isolated the operative field from lung lobes with the traction of pericardial adipose tissue. The preoperative data and perioperative clinical data of the two groups were compared and analyzed. Results There was no statistical difference in basic preoperative data between the two groups. The operation time in the OLV group was shorter than that in the TLV group (296.7±57.3 min vs. 334.1±87.0 min, P=0.000), and the duration of postoperative mechanical ventilation and ICU stay were not statistically different between the two groups. There was also no statistical difference in the incidence of pneumothorax or atelectasis between the two groups. Conclusion The triangular-sail technique is simple and easy to implement. The technique allows intermittent two-lung ventilation during MICS CABG procedure.

In February 2022, the world′s first gallbladder reporting and data system (GB-RADS) for the assessment of gallbladder wall thickening on ultrasonography was published in the form of an international expert consensus. The GB-RADS system classifies gallbladder wall thickening into six levels (GB-RADS 0?5), with gradually increasing risk of malignancy. It is mainly based on the following features: symmetry and extent (focal versus circumferential) of involvement, layered appearance, intramural features (including intramural cysts and echogenic foci), and interface with the liver. The proposed system is important for the standardized diagnosis and treatment of gallbladder diseases. The authors interpret the consensus, introduce the evaluation points and classification standards, and suggest the future applications and research directions.

Objective To compare and analyze the postoperative quality of life in patients after minimally invasive coronary artery bypass grafting (MICABG) and conventional median thoracotomy off-pump coronary artery bypass grafting surgery (OPCABG). Methods From November 2015 to January 2018, 94 patients who underwent MICABG in the Peking University Third Hospital were included in the MICABG group. During the same period 441 patients who received OPCABG were included in the OPCABG group. The patients were matched by using propensity score matching method with a ratio of 1∶1. The quality of life was compared between two groups at 1 month, 6 months and 12 months after the surgery using SF-36 scale. Results A total of 82 patients were matched for each group. In the MICABG group, there were 66 males and 16 females with a mean age of 62.6±8.2 years. In the OPCABG group, there were 67 males and 15 females with a mean age of 63.2±13.2 years. One month after the operation, the physical health assessment (PCS) and mental health assessment (MCS) of the MICABG group were higher than those of the OPCABG group (50.3±10.6 points vs. 46.1±10.3 points, P=0.011; 59.5±9.3 points vs. 54.2±11.0 points, P=0.002). Scores of these following five dimensions: general health, physical functioning (PF), role-physical, social functioning (SF), role-emotion in the MICABG group were higher than those in the OPCABG group, while the score of body pain was inferior to that in the OPCABG group, and the differences were statistically significant (P<0.05). Six months after the surgery, the PCS and MCS of the two groups were not statistically different (80.0±13.1 points vs. 77.8±12.4 points, P=0.271; 81.6±13.5 points vs. 80.4±11.2 points, P=0.537). However, the scores of PF and SF in the MICABG group were still higher than those in the OPCABG group (P<0.05). Twelve months after the surgery, there was no statistical difference in the score of each dimension between the two groups (P>0.05). Conclusion The improvement of quality of life within 6 months after MICABG is better than that of OPCABG, and it is similar between the two groups at 12 months after the surgery, indicating that MICABG has a certain effect of improving the short-term quality of life after the surgery, and the long-term quality of life is comparable to conventional surgery.
