Objective To investigate the benefits and drawbacks of breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer and treatment experience of postoperative operation-related complications. Methods A retrospective analysis was performed on clinical data of 26 female patients with breast cancer who met the selection criteria between September 2021 and March 2023 aging 48.7 years (range, 26-69 years). All tumors were unilateral, with 17 on the left side and 9 on the right side. The tumor size ranged from 1.0 to 7.0 cm, with an average of 2.7 cm. The pathological staging included T1 in 11 cases, T2 in 14 cases, and T3 in 1 case; N0 in 10 cases, N1 in 11 cases, N2 in 2 cases, and N3 in 3 cases; no distant metastasis (M0) occurred when first diagnosed. Among them, 10 cases underwent breast conserving surgery, and 16 cases underwent nipple-sparing mastectomy. All patients underwent breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap. The operation time, incision length, and postoperative drainage volume in 3 days were recorded. Breast-Q “Satisfaction with back” scale was conducted to evaluate patients’ satisfaction with back at 6 months after operation. Results The operation time was 280-480 minutes (mean, 376.7 minutes), the incision length was 10-15 cm (mean, 12.2 cm), the postoperative drainage volume in 3 days was 500-1 600 mL (mean, 930.2 mL). There were 4 cases of postoperative seroma, 1 case of incision rupture, 1 case of paresthesia of the thoracic wall, and 1 case of edema of the ipsilateral upper limb. All patients were followed up 12-30 months (mean, 20.1 months). No latissimus dorsi muscle flap necrosis, latissimus dorsi muscle atrophy, or shoulder joint dysfunction occurred during follow-up; 2 patients had recurrence of lymph nodes in the ipsilateral axilla after operation, but no distant metastasis occurred. Breast-Q score at 6 months after operation was 64-100 (mean, 79.5). The average score was 78.6 (range, 64-100) in patients underwent nipple-sparing mastectomy and 81.0 (range, 78-100) in patients underwent breast conserving surgery. Conclusion Breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer is proven to be a surgical approach with safety and cosmetic effects with mild postoperative operation-related complications and considerable patient satisfaction.
ObjectiveTo systematically review the efficacy and safety of single-port video-assisted thoracoscopic surgery (VATS) vs. multiple-port VATS in lobectomy for non-small cell lung cancer (NSCLC).MethodsThe PubMed, EMbase, the Cochrane Library, CBM, CNKI, Wanfang, VIP and Web of Science were searched to collect clinical studies about single- vs. multiple-port VATS for patients with NSCLC from inception to August 2018. The literatures were screened, data were extracted and the risk of bias of included studies was assessed independently by two reviewers. The meta-analysis with the collected data was performed by using RevMan 5.3 software.ResultsEleven studies (4 randomized controlled trials, 1 prospective cohort study and 6 retrospective cohort studies), including 1 574 patients. Among them, 779 patients were in the single-port group, and 795 in the multiple-port group. The results of meta-analysis showed that there was no significant difference between the two groups in the operation time (MD=3.60, 95%CI –8.59 to 15.79, P=0.56), the conversion rate (OR=1.06, 95%CI 0.54 to 2.06, P=0.87), the incidence of postoperative complications (OR=0.76, 95%CI 0.53 to 1.10, P=0.15), postoperative hospitalization time (MD=0.74, 95%CI –1.60 to 0.12, P=0.09), chest tube placement time (MD=0.63, 95%CI –1.28 to 0.02, P=0.06) or harvested lymph nodes (MD=–0.11, 95%CI –0.46 to 0.24, P=0.54). The intraoperative blood loss (MD=–17.12, 95%CI –31.16 to –3.08, P=0.02) was less in the single-port group than that in the multiple-port group. The visual analogue score (VAS) on postoperative first day (MD=–1.30, 95%CI –1.85 to –0.75, P<0.000 01) and on postoperative third day (MD=–0.82, 95%CI –1.00 to –0.65, P<0.000 01) were lower in the single-port group than those in the multiple-port group.ConclusionThe meta-analysis indicates that the efficacy of single-port VATS for NSCLC is equivalent to multiple-port VATS. However the intraoperative blood loss, the VAS scores on postoperative first and third days in the single-port group are better.
ObjectiveTo analyze the occurrence of postoperative pulmonary complications (PPC) and the risk factors in patients with spontaneous pneumothorax who underwent micro single-port video-assisted thoracoscopic surgery (VATS).MethodsA total of 158 patients with spontaneous pneumothorax who underwent micro single-port VATS in our hospital from April 2017 to December 2019 were retrospectively included, including 99 males and 59 females, with an average age of 40.53±9.97 years. The patients were divided into a PPC group (n=21) and a non-PPC group (n=137) according to whether PPC occurred after the operation, and the risk factors for the occurrence of PPC were analyzed.ResultsAll 158 patients successfully completed the micro single-port VATS, and there was no intraoperative death. The postoperative chest tightness, chest pain, and dyspnea symptoms basically disappeared. During the postoperative period, there were 3 patients of pulmonary infection, 7 patients of atelectasis, 4 patients of pulmonary leak, 6 patients of pleural effusion, 1 patient of atelectasis and pleural effusion, and the incidence of PPC was 13.29% (21/158). Multivariate logistic regression analysis showed that lung disease [OR=32.404, 95%CI (2.717, 386.452), P=0.006], preoperative albumin level≤35 g/L [OR=14.912, 95%CI (1.719, 129.353), P=0.014], severe pleural adhesions [OR=26.023, 95%CI (3.294, 205.557), P=0.002], pain grade Ⅱ-Ⅲ 24 hours after the surgery [OR=64.024, 95%CI (3.606, 1 136.677), P=0.005] , age [OR=1.195, 95%CI (1.065, 1.342), P=0.002], intraoperative blood loss [OR=1.087, 95%CI (1.018, 1.162), P=0.013] were the risk factors for PPC after micro single-port VATS.ConclusionThere is a close relationship between PPC after micro single-port VATS and perioperative indexes in patients with spontaneous pneumothorax. Clinically, targeted prevention and treatment can be implemented according to the age, pulmonary disease, preoperative albumin level, intraoperative blood loss, degree of pleural adhesion and pain grading 24 hours after surgery.
ObjectiveTo explore the efficacy of single-port thoracoscopic anatomical lung segmentectomy in treating Stage IA non-small-cell lung cancer (NSCLC) and to analyze its impact on the body's stress response and lung function. MethodsA retrospective analysis was conducted on the clinical data of patients with stageⅠA NSCLC admitted to the Second Affiliated Hospital, Air Force Military Medical University, from January 2021 to June 2022. Patients were divided into two groups based on their treatment plans: those who underwent single-port thoracoscopic lobectomy were in the lobe group, and those who underwent single-port thoracoscopic anatomical lung segmentectomy were in the segment group. The surgical-related indicators, complication rates, survival rates of the two groups were compared, as well as the body's stress response indicators before and after surgery [C-reactive protein (CRP), interleukin-6 (IL-6), cortisol (Cor), creatine kinase (CK)], prognostic lung function indicators [forced vital capacity (FVC), maximal voluntary ventilation (MVV), forced expiratory volume in one second (FEV1), FEV1/FVC ratio], and auxiliary tumor markers [carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), CA724, cyto-keratin 21-1 fragment (CYFRA21-1)]. ResultsEach group included 53 patients, with 29 males and 24 females in the segment group, with an average age of (70.38±3.67) years; and 26 males and 27 females in the lobe group, averaging an age of (71.09±3.80) years. The intraoperative blood loss in the segment group was less than that in the lobe group [(118.41±14.58) mL vs. (130.36±10.61) mL, P＜0.001], and the hospital stay was shorter in the segment group [(7.13±1.14) d vs. (8.52±1.33) d, P＜0.001]. One day and three days post-surgery, the serum levels of CRP, IL-6, Cor, and CK in the segment group were lower those in the lobe group, while the levels of FVC, FEV1, FEV1/FVC ratio, and MVV were higher (P＜0.05). One month and three months post-surgery, the serum levels of CEA, CA125, CA724, and CYFRA21-1 in the segment group showed no statistically significant difference compared to the lobe group (P＞0.05); the incidence of postoperative complications and survival rates in the segment group were 3.77% and 80.39%, respectively, while they were 7.55% and 76.92% in the lobe group, respectively, with no statistical difference between the two groups (P＞0.05). ConclusionSingle-port thoracoscopic anatomical lung segmentectomy for stage ⅠA NSCLC has significant advantages in reducing intraoperative damage, stabilizing the body's stress response, and has less impact on lung function, which is beneficial for postoperative recovery.
ObjectiveTo compare the safety of the incision along the upper umbilical margin (referred to as the “upper incision”) versus the transverse umbilical incision (referred to as the “transverse incision”) for single-port bariatric surgery, and to assess their effects on postoperative scar appearance and patient’s psychological adaptation. MethodsThis study was designed as a multi-center retrospective analysis. The patients who underwent bariatric surgery via the upper incision and transverse incision at the Third People’s Hospital of Chengdu, Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, and the First Affiliated Hospital of Jinan University from December 2024 to April 2025. The incidence of postoperative complications and the pionts of scar appearance (evaluated using the POSAS 3.0 scale) and psychological adaptation (measured with the BODY-Q scale) between the two incision methods were compared. Furthermore, multiple linear regression model was employed to evaluate the impact of different incision methods on points of scar appearance and psychological adaptation. ResultsA total of 194 patients who underwent single-port bariatric surgery were included, with 134 in the transverse incision group and 60 in the upper incision group. There was no statistically significant difference in the total incidence of incision complications between the transverse and upper incision groups [11.9% (16/134) vs. 18.3% (11/60), χ2=0.930, P=0.335]. The transverse incision group showed significantly better outcomes than the upper incision group in the overall points of BODY-Q scale [(39.86±1.02) points vs. (37.63±4.70) points, t=–6.090, P<0.001] and POSAS scale [(17.60±2.35) points vs. (21.25±6.00) points, t=5.239, P<0.001]. After adjusting for potential confounding factors such as history of diabetes mellitus, education level, smoking status, alcohol consumption status, keloid tendency, and use of scar improvement products in the multiple linear regression model, the advantage of the transverse incision remained significant [β(95%CI)=–1.81 (–2.84, –0.78), P<0.001]. Conclusions This study demonstrates that the transverse incision significantly improves the overall appearance of the postoperative scar and enhances patient’s psychological adaptation compared to the upper incision in single-port bariatric surgery. This advantage persists independently after adjusting for multiple confounding factors. Therefore, the transverse incision could be considered a more favorable approach in terms of cosmetic outcomes and patient’s psychological adaptation.
ObjectiveTo compare the effectiveness of sequential method pure single-port lumpectomy-breast conserving surgery (SMPSL-BCS) in treating early-stage breast cancer patients with tumors in different quadrants. Methods A retrospective analysis was conducted on 200 early-stage breast cancer female patients admitted between January 2023 and December 2023. According to the quadrant where the tumor was located, the patients were allocated into the upper outer quadrant group (UO group), lower outer quadrant group (LO group), upper inner quadrant group (UI group), and lower inner quadrant group (LI group), with 50 cases in each group. There was no significant difference (P>0.05) in the baseline data, including age, body mass index, smoking history, marital status, comorbidities, affected breast side, maximum tumor diameter on ultrasound, maximum pathological tumor diameter, clinical tumor stage, molecular subtype, and disease duration. The operation time, intraoperative blood loss, postoperative drainage volume, and extubation time were recorded and compared between groups. Additionally, the occurrence of early-stage complications (1-3 months after operation; including subcutaneous fluid accumulation, incision infection, superficial skin burns) and late-stage complications (>3 months after operation; including pectoralis major muscle adhesion, changes in breast appearance and shape, sensory discomfort) were assessed. At 6 months after operation, the cosmetic outcome of breast-conserving surgery was rated for all groups. Results The UO group had the shortest operation time, followed by the UI group, LO group, and LI group, showing significant differences between groups (P<0.05). The UO group had the least intraoperative blood loss, followed by the LO group, UI group, and LI group; except for the difference between UO group and LO group, which was not significant (P>0.05), the differences between the other groups were significant (P<0.05). The UO group had the least postoperative drainage volume, followed by the LO group, UI group, and LI group; except for the difference between LO group and UI group, which was not significant (P>0.05), the differences between the other groups were significant (P<0.05). The extubation time of the LI group was significantly longer than that of the other groups (P<0.05). All patients were followed up 4-12 months, with an average of 8 months. And 193 patients were followed up more than 6 months, including 48 patients in UO group, 47 in LO group, 49 in UI group, and 49 in LI group. In the early-stage period, the LI group had a higher incidence of subcutaneous fluid accumulation after tube removal compared to the UO group and LO group (P<0.05), while there was no significant difference in the incidences of other early complications between groups (P>0.05). In the late-stage period, the LI group had significantly higher incidences of pectoralis major muscle adhesion and changes in breast appearance and shape than UO group and LO group (P<0.05), and a significantly higher incidence of sensory discomfort than UO group (P<0.05). There was no significant difference in the incidences of other late-stage complications between groups (P>0.05). At 6 months after operation, the cosmetic outcomes of breast-conserving surgery were significantly better in UO group, LO group, and UI group than in LI group (P<0.05); there was no significant difference between the other groups (P>0.05). Conclusion In the treatment of early-stage breast cancer using SMPSL-BCS, patients with tumors located in the upper outer quadrant show the best effectiveness. The effectivenesses are similar for patients with tumors in the lower outer and upper inner quadrants. However, patients with tumors in the lower inner quadrant do not experience significant advantages. Therefore, it is recommended that SMPSL-BCS should not be the first-choice surgical method for patients with tumors in the lower inner quadrant.
ObjectiveTo analyze the feasibility, advantages and disadvantages of the fluorescence method and the inflation-deflation method in defining the intersegmental plane during thoracoscopic lung segmental resection.MethodsFrom February to October 2018, 60 patients underwent thoracoscopic anatomical segmentectomy in Thoracic Surgery Department of Nanjing Chest Hospital, with 28 males and 32 females, aged from 25 to 82 years. Three-dimension computed tomography bronchography and angiography was used to reconstruct pulmonary vessels, bronchus and virtual intersegmental plane. Among them, 20 patients used the fluorescence method to define the intersegmental plane, and the other 40 patients used the traditional inflation-deflation method to define the intersegmental plane.ResultsFluorescent injection of indocyanine green (ICG) showed a clear intersegmental line with a duration sufficient to complete the label. With the fluorescence method, the intersegmental plane occurrence time was significantly shortened (10.75±3.78 s vs. 988.00±314.24 s, P<0.001) and had satisfactory repeatability. The lungs did not need to be inflated, which was convenient for the operation. And the operation time was shortened (108.75±31.28 min vs 138.00±32.47 min, P=0.002). No obvious ICG injection-related concurrency symptoms was found.ConclusionCompared with the traditional inflation-deflation method, the fluorescence method can display the intersegmental line quickly, accurately and clearly, reduce the difficulty of surgery, shorten the operation time, and provide reliable technical support for thoracoscopic anatomical segmentectomy. The fluorescence is a safe and effective method that is worthy of clinical application.
Objective To explore the safety and feasibility of preferential manual bronchoplasty in single-port video-assisted thoracoscopic surgery (VATS) upper lobectomy. MethodsThe clinical data of 457 patients with non-small cell lung cancer who underwent single-port VATS lobectomy in the Department of Thoracic Surgery of Peking University First Hospital from March 2020 to March 2022 were retrospectively analyzed. The patients were divided into a preferential manual bronchoplasty group and a traditional single-port VATS lobectomy group with a 1 : 1 propensity score matching for further research. Results A total of 204 patients were matched, and there were 102 patients in each group. There were 50 males and 52 females aged 62.2±10.1 years in the preferential bronchoplasty group, and 49 males and 53 females aged 61.2±10.7 years in the traditional single-port VATS group. The preferential bronchoplasty group had shorter surgical time (154.4±37.0 min vs. 221.2±68.9 min, P<0.01), less bleeding (66.5±116.9 mL vs. 288.6±754.5 mL, P=0.02), more lymph node dissection (19.8±7.5 vs. 15.2±4.7, P<0.01), and a lower conversion rate to multi-port or open surgery (2.3% vs. 13.8%, P=0.04) in left upper lobe resection. In the right upper lobe resection surgery, there was no statistical difference in postoperative results between two groups. There was no perioperative death or occurrence of bronchopleural fistula in both groups. ConclusionCompared with traditional single-port VATS upper lobectomy, preferential bronchoplasty has similar safety and feasibility. In addition, priority bronchoplasty in left upper lobectomy has the advantages of shorter surgical time, less bleeding, more lymph node dissection, and lower conversion rate to multi-port or open surgery.
ObjectiveTo assess the feasibility and safety of ultra-micro 5 mm single-port endoscopic thoracic sympathicotomy in selected patients with primary palmar hyperhidrosis. MethodsFrom March 1, 2018 to February 1, 2021, 90 patients with primary palmar hyperhidrosis who underwent ultra-micro 5 mm single-port endoscopic thoracic sympathicotomy at the Thoracic Surgery Department of the University of Hong Kong-Shenzhen Hospital. There were 47 males and 43 females, with a median age of 26.0 (22.0, 31.0) years. During the operation, T3 and/or T4 thoracic sympathetic nerve chain was transected using an ultra-micro 5 mm single-port incision near the areola or under the axilla. The surgical data of the patients were retrospectively reviewed and analyzed. Results All patients successfully completed the operation without major bleeding during the operation and no conversion to thoracotomy. There was no death or serious complication during the perioperative period. The operation time was 43.0 (23.0, 60.0) min, and the intraoperative blood loss was 2.0 (1.0, 2.0) mL. In the perioperative period, only one patient needed a tiny chest tube indwelling. The symptoms of hyperhidrosis on the hands all disappeared after the operation. The pain score on the postoperative day was 2.0 (2.0, 2.0) points. The hospital stay after surgery was 1.0 (1.0, 1.0) d. In the first month after the operation, the symptoms of hyperhidrosis on the hands were significantly relieved compared with those before the operation. The surgical incisions healed well, the wounds were concealed, and there was no wound infection or poor healing. The patients' satisfaction with the surgical incisions was 100.0%. After the operation, 14 (15.6%) patients had mild compensatory hyperhidrosis, 5 (5.6%) patients had moderate compensatory hyperhidrosis, and no patient had severe compensatory hyperhidrosis. Overall satisfaction rate was 94.0%. Conclusion The clinical application of ultra-micro 5 mmsingle-port endoscopic thoracic sympathicotomy in selected patients with primary palmar hyperhidrosis is safe and feasible. The surgical wound is extremely small and hidden, the operation time is short, the pain is very slight, and the clinical outcome is good. It can fully meet the patients' pursuit of beauty.
ObjectiveTo systematically evaluate the effect of single-port totally extraperitoneal (SPTEP) and conventional totally extraperitoneal (CTEP) inguinal hernia repair in treatment of inguinal hernia. MethodsPubMed, Cochrane Library, Embase, WanFang Data, VIP, and CNKI databases were electronically searched and the randomized controlled trial (RCT) and non-RCT studies on the efficacy and safety of SPTEP versus CTEP for patients with inguinal hernia from January 2010 to November 2019 were collected. Two reviewers independently screened literatures, extracted data, and assessed risk of bias of included studies, then the meta-analysis was performed by using RevMan5.3 software. ResultsA total of 17 clinical studies were included in the analysis, with 1 106 cases in the SPTEP group and 966 cases in the CTEP group. The results of meta-analysis showed that: the hospital stay [SMD=–0.12, 95%CI (–0.22, –0.02), P=0.01] and the time to resume normal activity [SMD=–1.17, 95%CI (–2.10, –0.23), P=0.01] were shorter, the satisfaction score of incision scars [SMD=0.92, 95%CI (0.31, 1.53), P<0.01] was higher in the SPTEP group as compared with the CTEP group. However, the operative time of SPTEP group was longer than that of the CTEP group both for unilateral inguinal hernia [MD=4.08, 95%CI (0.34, 7.83), P=0.03] and bilateral inguinal hernia [MD=5.53, 95%CI (0.39, 10.68), P=0.04]. There were no statistical differences in the postoperative pain score (24 h and 7 d), incidence of postoperative complications, the rate of patients satisfied with the incision, and hospitalization costs between the two groups (P>0.05). ConclusionsFrom the results of this meta-analysis, SPTEP has some certain advantages in shortening hospital stay and returning to normal activity time, and improving incision satisfaction. However, compared with CTEP, mean operative time of SPTEP is longer. Although SPTEP has developed for several years, it is difficult to replace CTEP.
