  • Clinical outcomes of thoracoscopic pulmonary segmentectomy

    ObjectiveTo explore the clinical issues associated with video-assisted pulmonary segmentectomy and to provide reference for better implementation of thoracoscopic pulmonary segmentectomy and reduction of perioperative complications through analyzing the clinical results of thoracoscopic segmentectomy.MethodsThe clinical data of 90 patients who planned to undergo thoracoscopic segmentectomy in our department from October 2017 to December 2019 were retrospectively analyzed, including 35 males with an average age of 60.34±9.40 years and 55 females with an average age of 56.09±12.11 years. The data including lung nodule number, benign or malignant, preoperative location by Hookwire, preoperative planning and actual implementation, operation time, intraoperative blood loss, postoperative drainage volume and time of drainage tube removal, postoperative hospital stay and complications were collected and analyzed.ResultsAmong the 90 patients, 38 were preoperatively positioned by Hook-wire, 52 were directly operated on; 87 were completed under thoracoscopic surgery among whom 3 underwent passive lobectomy after segmentectomy under thoracoscopic surgery, and 3 were converted to thoracotomy among whom 1 underwent lobectomy. Operation time was 198.58±56.42 min, intraoperative blood loss was 129.78±67.51 mL, lymph node samples were 6.43±1.41, drainage time was 2.98±1.25 d, the amount of postoperation drainage was 480.00±262.00 mL, hospital stay was 7.60±2.38 d. In all patients, 73 had single nodules and 17 had multiple nodules. Totally 113 pulmonary nodules were resected, 14 (12.39%) were benign nodules and 99 (87.61%) were malignant nodules. There was no perioperative death or serious complications.ConclusionFor those pulmonary parenchymal nodules which meet the indications, it is feasible to perform thoracoscopic anatomic pulmonary segmentectomy according to preoperative thin-slice CT and three-dimensional computed tomography-bronchography and angiography (3D-CTBA) reconstruction results. Preoperative Hookwire localization can ensure effective edge resection and reduce unplanned lobotomy for intersegmental nodules and non-palpable peripheral pure ground-glass nodules.

  • Thoracoscopic combined subsegmentectomy for 76 patients: A retrospective study in a single center

    ObjectiveTo summarize the clinical experience of thoracoscopic combined subsegmentectomy (CSS). MethodsThe clinical data of 76 patients who underwent thoracoscopic CSS in Anqing Municipal Hospital from May 2018 to July 2022 were retrospectively analyzed, including 22 males and 54 females, aged 27.0-76.0 (54.3±10.5) years. All patients underwent preoperative three-dimensional computed tomography bronchography and angiography using dual source CT. The modified inflation-deflation technique or indocyanine green was used to identify the intersubsegmental border. ResultsA total of 86 pulmonary nodules were resected in 76 patients. One patient of left upper lobe S1+2c+S4a, 1 patient of right upper lobe S2b+S3a and 1 patient of right upper lobe S1b+S3b were further performed lobectomy due to insufficient margin. One patient of left upper lobe S1+2+S3a was further performed left upper division segmentectomy due to residual atelectasis. One patient of left upper lobe S1+2c+S3a was further performed left upper division segmentectomy due to B3b+c injury, and the rest completed planned surgeries successfully. The operative time was 90.0-350.0 (174.9±53.2) min. The operative hemorrhage volume was 50.0 (20.0, 50.0) mL. The postoperative hospital stay time was 6.0 (5.0, 7.0) d. Postoperative complications included pulmonary infection in 9 patients, hemoptysis in 3 patients, persistent pulmonary leakage>3 d in 4 patients, pneumothorax in 1 patient, pleural effusion in 1 patient, and myocardial infarction in 1 patient. All of the patients were cured and discharged without perioperative death. ConclusionThoracoscopic CSS is relatively complex. Preoperative planning under three-dimensional reconstruction and intraoperative fine operation are helpful for safe completion.

  • Modified jejunostomy in the application of thoracoscopic Ivor-Lewis esophageal surgery: A retrospective cohort study

    Objective To evaluate the application effect of modified jejunostomy in thoracoscopic Ivor-Lewis esophagectomy. Methods A retrospective analysis of patients who underwent Ivor-Lewis esophagectomy for middle and lower esophageal cancer from 2017 to 2023 in our department was performed. The patients from 2017 to 2020 receiving "C+I" in the upper jejunum according to the "C+I" model, and fistula fixed with only two purse-string sutures and the abdominal wall were allocated into a group A. The patients from 2021 to 2023, on the basis of "C+I" suture, the jejunum and abdominal wall fixed with 3-0 absorbable thread for 1-2 needles at the proximal or distal end of the fistula 10-15 mm, and the upper jejunum and abdominal wall fixed into "curtain" were allocated into a group B. The operation time, jejunostomy time, postoperative pathological stage, and enteral nutrition-related complications such as the incidence of incomplete intestinal obstruction, closed loop intestinal obstruction and intestinal volvulus requiring secondary surgery, skin redness and swelling of intestinal fluid leakage, stoma tube blockage, and accidental extubation were compared between the two groups. Results All patients successfully completed Ivor-Lewis esophagectomy under thoracoscopy. There was no perioperative death. There were 118 patients in the group A, including 72 males and 46 females, with an average age of 64.58±6.30 years. There were 125 patients in the group B, including 76 males and 49 females, with an average age of 65.11±6.81 years. There was no statistical difference in operation time, jejunal fistula time, fistula blockage or accidental extubation rate between the two groups (P>0.05). There was a statistical difference in the incidence of incomplete intestinal obstruction (P=0.035), and closed loop intestinal obstruction requiring secondary surgery (P=0.017). There were 36 patients of eczema-like changes in the patients with severe intestinal leakage and redness in the group A, and 7 patients of intestinal leakage and redness in the group B (P<0.001). Conclusion The modified jejunostomy can significantly reduce the incomplete intestinal obstruction, closed loop intestinal obstruction and secondary operation rate after "C+I" jejunostomy, and significantly improve the leakage of intestinal fluid at the stoma and the injury of surrounding skin and soft tissue. Improvements in certain technologies reduce operational difficulties and is worthy of promotion and application in clinical practice.
