ObjectiveTo investigate the safety, feasibility and advantages of subxiphoid uni-portal thoracoscopic thymectomy.MethodsClinical data of 65 patients undergoing subxiphoid uni-portal thoracoscopic thymectomy in our hospital from September 2018 to March 2019 were retrospectively analyzed. They were treated as a subxiphoid surgery group, including 36 males and 29 females, aged 49.5 (29-71) years. The incision with the length of about 3 cm was located approximately 1 cm under the xiphoid process. From January 2016 to December 2017, 65 patients received intercostal uni-portal thoracoscopic thymectomy, who were treated as a control group, including 38 males and 27 females, aged 48.9 (33-67) years. All patients who were clinically diagnosed with thymic tumor before surgery were treated with total thymectomy. After surgery, expectoration and analgesia were used.ResultsThere was no statistically significant difference in general clinical data, lesion size, intraoperative blood loss, postoperative catheterization time, postoperative hospital stay and postoperative pathology between the two groups. All operations were successfully completed, and the patients in both groups recovered uneventfully after surgery. Visual analogue scale scores on the 1st, 3rd, 7th and 30th day after surgery in the subxiphoid surgery group were lower than those in the control group.ConclusionThe subxiphoid uni-portal thoracoscopic approach can achieve total thymectomy with less trauma and faster postoperative recovery.
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 investigate the efficacy of uniportal video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy.MethodsThe clinical data of 15 patients who underwent uniportal VATS anatomic basal segmentectomy between June 2020 and December 2020 were retrospectively reviewed. There were 4 males and 11 females with a median age of 53 (32-70) years. The incisions were placed in the fifth intercostal space across the mid-axillary line. All basal segmentectomies were performed through the interlobar fissure or inferior pulmonary ligament approach following the strategies of single-direction and stem-branch.ResultsAll patients underwent basal segmentectomy successfully with no conversion to multi-portal procedure or thoracotomy. The median operation time was 120 (90-160) min, median intraoperative blood loss was 20 (10-50) mL, median drainage time was 3 (2-5) d, and median postoperative hospital stay was 4 (4-10) d. The maximum diameter of the lesion in the resected basal segment was 1.2 (0.7-1.9) cm. The median resected lymph nodes were 7 (5-12). There was no evidence of nodal metastases. One patient suffered postoperative atelectasis and subsequent pneumonia. No perioperative death occurred.ConclusionUniportal VATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.
Objective To investigate the advantage of the concept of wide exposure in uniportal video-assisted thoracoscopic surgery (uniportal-VATS) for radical resection of lung cancer and assess its safety and feasibility. Methods Clinical data of 255 patients (110 males and 145 females, a mean age of 54.3±7.9 years) with non-small cell lung cancer (NSCLC) who received wide exposure in uniportal-VATS or three portal VATS (3P-VATS) during August 2017 to March 2018 were retrospectively analyzed. There were 153 patients (67 males and 86 females, a mean age of 56.1±8.5 years) in the uniportal-VATS group and 102 patients (43 males and 59 femals, a mean age of 54.4±7.4 years) in the 3P-VATS group. The clinical effects were compared between the two groups. Results There was no statistical difference in the operation time between the uniportal-VATS and 3P-VATS (135.0±45.6 min vs. 142.0±39.5 min, P>0.05). The overall number of dissected stations (6.9±1.0) and LNs (14.5±3.0) in the uniportal-VATS group were similar with those in the 3P-VATS group (7.1±1.0, 15.1±1.7). The dissected stations of N2 LNs (uniportal-VATS: 4.1±1.7, 3P-VATS: 3.9±0.8) and number of dissected N2 LNs (uniportal-VATS: 8.0±0.9, 3P-VATS: 7.8±1.1) were both similar between the two groups. The duration of postoperative tube drainage and postoperative hospital stay of uniportal-VATS group (3.5±1.8 d and 7.2±0.9 d) were much shorter than those of 3P-VATS group (4.0±1.3 d and 8.8±2.0 d). No significant difference was found in incidence of postoperative complication between the two groups except that the incidence of subcutaneous emphysema in the uniportal-VATS group was much lower. There was no perioperative death in the two groups. Conclusion The concept of wide exposure in uniportal-VATS can meet the requirment of radical resection and it is a safe and valid method which can be used for radical resection of lung cancer.
ObjectiveTo compare clinical efficacy between transumbilical three-port laparoscopic surgery (TU-TPLS) and transumbilical single-incision laparoscopic surgery (TU-SILS) in repair of acute peptic ulcer perforation. MethodsThe patients with acute peptic ulcer perforation who underwent TU-TPLS or TU-SILS in Chengdu Second People’s Hospital Affiliated to Sichuan University from January 2022 to December 2024 were retrospectively collected, and then were divided into the TU-TPLS group and TU-SILS group. The operation time, postoperative 24 h incision pain score (visual analogue scale) , postoperative hospital stay, total hospitalization cost, incision scar score (Vancouver scar scale), comprehensive satisfaction, and postoperative complications were compared between the two groups. ResultsA total of 105 patients met the inclusion criteria were enrolled, comprising 50 patients in the TU-TPLS group and 55 patients in the TU-SILS. There were no statistically significant differences in baseline characteristics between the two groups, such as gender, age, body mass index, perforation site, perforation diameter, and Boey score (all P>0.05). Postoperatively, the TU-TPLS group demonstrated significantly lower visual analogue scale pain score at 24 h compared to the TU-SILS group [(2.34±0.63) score vs. (3.22±1.05) score, P<0.001] and significantly higher comprehensive satisfaction score [(7.60±0.86) score vs. (7.02±1.01) score, P=0.002]. However, no statistically significant differences were observed between the TU-TPLS group and TU-SILS group regarding operative time [(71.84±10.51) min vs. (69.78±7.98) min, P=0.257], postoperative hospital stay [(10.35±2.08) d vs. (9.96±1.75) d, P=0.310], or total hospitalization costs [(20 856.23±4 095.73) yuan vs. (19 988.83±2 933.43) yuan, P=0.212]. The incidence of umbilical wound infection was 1 case in the TU-TPLS group and 3 cases in the TU-SILS group (P=0.619). Postoperative residual intra-abdominal infection occurred in 2 cases in the TU-TPLS group and 1 case in the TU-SILS group (P=0.604). Incisional bleeding occurred in 0 case in the TU-TPLS group and 1 case in the TU-SILS group (P>0.999). Furthermore, there was no statistically significant difference in the scar assessment score between the TU-TPLS group and TU-SILS group [(3.11±1.13) score vs. (2.92±0.70) score, P=0.301] at the 2-month postoperative follow-up. ConclusionsBoth TU-TPLS and TU-SILS have achieved good therapeutic effects in treatment of acute peptic ulcer perforation. However, TU-TPLS has more advantages over TU-SILS. TU-TPLS causes milder incision pain, leads to higher patient satisfaction, and does not require special equipment.
Objective To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.
