Utility of preoperative 18F-flurodeoxyglucose PET/CT scanning in preoperative evaluation and surgical planning for pulmonary tuberculosis

Objective The objective of this study was to investigate the utility of preoperative 18F-FDG PET/CT scanning in preoperative evaluation and surgical planning for pulmonary tuberculosis. Methods The study involved a retrospective analysis of clinical data and preoperative chest 18F-FDG PET/CT data of 24 patients with pulmonary tuberculosis who underwent pneumonectomy at the Shanghai Public Health Clinical Center between December 2017 and January 2022. Results All 24 patients successfully underwent chest 18F-FDG PET/CT imaging, and complete data pertaining to the maximum standardized uptake value, mean standardized uptake value, minimum standardized uptake value, total lesion glycolysis, and metabolic tumor volume were obtained. Surgical excision plans were finalized using the chest 18F-FDG PET/CT findings along with the conventional chest CT scans. Pneumonectomy was successfully completed in all 24 patients, and these included 13 cases of pulmonary lobectomy, two cases of total pneumonectomy, one case of combined pulmonary lobectomy, one case of segmentectomy, and seven cases of pulmonary wedge resection. The actual surgical procedures had a conformity rate of 100% to the preoperative surgical plans that were made. The intraoperative bronchial stump embedding rate was 69% (11/18 cases), the incidence rate of postoperative air leakage was 3.8% (1/24 cases), and there were no reported cases of postoperative bronchopleural fistula or death. Conclusion Preoperative 18F-FDG PET/CT scans had significant utility in surgical planning, the selection of surgical methods, and the formulation of postoperative antituberculosis treatment courses for patients with pulmonary tuberculosis. The use of 18F-FDG PET/CT shows considerable promise in being promoted clinically for the surgical management of patients with pulmonary tuberculosis.

A case of right middle lobectomy for primary lung cancer in a patient with heterotaxy syndrome

BackgroundAnatomical abnormalities in the pulmonary vessels have long aroused great interest among thoracic surgeons, and numerous variations of pulmonary vessels have been reported. Heterotaxy syndrome is an anatomical abnormality in which typically asymmetrical organs, including the lungs, develop symmetrically. We report the case of a 71-year-old man with heterotaxy syndrome undergoing radical lobectomy in the treatment of non-small cell lung cancer.Case presentationComputed tomography (CT) revealed an irregular nodule 25 mm in diameter in the right middle lobe. Two months later, at his first visit to our University Hospital, CT revealed a rapidly growing tumor 60 mm in diameter. In addition, three-dimensional (3D) CT revealed the upper and middle lobar bronchi forming a common trunk with the mediastinal type of the right pulmonary artery (PA). The patient underwent video-assisted right middle lobectomy + systematic complete hilar and mediastinal lymph node dissection. The interlobar fissure between the right upper and middle lobes was incomplete, and the common trunk formed by the upper-middle bronchus emerged from an area between the right PA (A1+3) and the right superior pulmonary vein.ConclusionThe finding of A4+5 branching from the right main PA and descending posterior to the right upper-middle bronchus, which formed a common trunk, resembled a mirror image of the normal left lung. To our knowledge, a common trunk with the mediastinal type of the right PA has never been reported during video-assisted right middle lobectomy. In patients with heterotaxy syndrome, 3D-CT to preoperatively understand their anatomy is essential.

Corrected partial anomalous pulmonary vein connection associated with lung resection: a case report

IntroductionPartial anomalous pulmonary venous connection (PAPVC) is a potential cause of right-sided heart failure. Notably, a risk of sudden circulatory failure exists during lung surgery. Only a few reports of PAPVC complicated by lung cancer requiring lobectomy exist. Here, we report a case of left lower lung lobectomy complicated by an anomalous connection of the left upper pulmonary vein requiring revascularization.Case presentationA 66-year-old man was found with an abnormal mass shadow in the left lower lung field on chest radiography. Bronchoscopy revealed lung adenocarcinoma. Preoperative contrast-enhanced computed tomography showed that the left upper pulmonary vein did not perfuse the left atrium but was connected to the left brachiocephalic vein. Preoperative transthoracic echocardiography revealed right atrial and ventricular enlargement. The clinical diagnosis was stage IB (T2aN0M0). We decided to perform a left lower lobectomy and correct the PAPVC to maintain oxygenation after the lobectomy. The PAPVC was ligated, and the stump of the left upper pulmonary vein was anastomosed to the left atrial appendage without cardiopulmonary bypass. Postoperative contrast-enhanced computed tomography revealed intact reconstructed vessels. Postoperative transthoracic echocardiography showed no right ventricular overload. The patient’s postoperative clinical course following the surgical procedure was uneventful. Furthermore, the patient was followed up without any complications.ConclusionsThis rare case of successful surgical correction can inform clinicians of similar cases.

Clinicoradiologic Predictors of Anastomotic Complications After Bronchoplasty for Lung Cancer

BackgroundWe investigated the predictive factors for anastomotic complications in sleeve lobectomy for lung cancer. MethodsBetween February 2008 and April 2023, 196 patients underwent sleeve lobectomy for lung cancer; 140 were included after exclusion of those who underwent extended sleeve lobectomy and salvage surgery after definitive chemoradiotherapy. Clinicopathologic and computed tomography (CT) findings were retrospectively investigated, and predictors of anastomotic complications were analyzed. The CT finding of azygos arch invasion was defined as a compression or stenosis of the azygos arch by the tumor. ResultsLobectomy types were right upper lobectomy in 71 patients, right lower lobectomy in 5, left upper lobectomy in 53, and left lower lobectomy in 11. CT finding of azygos arch invasion was detected in 21 cases. Anastomotic coverage was performed in 41. Bronchial anastomotic complications were observed in 11 patients (7.9%), including 9 with an anastomotic fistula and 2 with stenosis, all of which were on the right side. Only right upper sleeve lobectomy was a significant predictor of anastomotic complications (odds ratio, 5.29; 95% CI, 1.07-26.13). In 71 cases of right upper sleeve lobectomy, anastomotic complications were significantly more frequent (33.3% vs 4.0%; P < .01) and predictive of anastomotic complications when tumor invasion into the azygos arch was detected on CT (odds ratio, 12.00; 95% CI, 2.24-64.42). ConclusionsRight upper sleeve lobectomy is a predictor of anastomotic complications. Particular attention should be paid to anastomotic complications in right upper sleeve lobectomy with suspected tumor invasion of the azygos arch on CT.

Robotic Lobectomy with a Single Robotic Stapler from One 12-mm Port: A Multi-institutional Study.

Introduction of the robotic stapler has allowed robotic lobectomy to be performed from a surgical console in complete autonomy. The robotic stapler fits a 12-mm port, which is larger than the standard 8-mm port and increases the risk of postoperative pain. However, in many cases, to cover all possible angles of approach, two 12-mm ports are preferably used. However, limiting instrument inventory and simplifying surgical procedures are also desirable to reduce costs. In a multicenter study, we assessed the feasibility of robotic lobectomy with a single type of robotic stapler [SureForm45 Curved-Tip (SF45C); Intuitive Surgical Inc.] inserted through one 12-mm port placed at the anterior tip of the lower intercostal space. We also investigated the potential cost savings of using an additional 60-mm stapler for interlobar division. A total of 135 lobectomy cases were enrolled. In all cases, all stapling procedures were completed using the SF45C inserted from the designated 12-mm port. We found that it was potentially less expensive to use the SureForm60 stapler if more than six SF45C reloads were needed for interlobar division. However, in our series, only 1 case (0.7%) met this requirement. The use of a single type of stapler from one 12-mm port in a robotic lobectomy is technically feasible. This approach may be expected to allow for surgical simplification, minimize the risk of postoperative pain, and reduce inventory costs.

Impact of the Size and Depth of Pulmonary Nodules on the Surgical Approach for Lung Resection in the Treatment of Early-stage Lung Cancer ≤2 cm

Current studies suggest that for early-stage lung cancers with a component of ground-glass opacity measuring ≤2 cm, sublobar resection is suitable if it ensures adequate margins. However, lobectomy may be necessary for some cases to achieve this. The aim of this study was to explore the impact of size and depth on surgical techniques for wedge resection, segmentectomy, and lobectomy in early-stage lung cancer ≤2 cm, and to determine methods for ensuring a safe resection margin during sublobar resections. Clinical data from 385 patients with early-stage lung cancer ≤2 cm, who underwent lung resection in 2022, were subject to a retrospective analysis, covering three types of procedures: wedge resection, segmentectomy and lobectomy. The depth indicator as the OA value, which is the shortest distance from the inner edge of a pulmonary nodule to the opening of the corresponding bronchus, and the AB value, which is the distance from the inner edge of the nodule to the pleura, were measured. For cases undergoing lobectomy and segmentectomy, three-dimensional computed tomography bronchography and angiography (3D-CTBA) was performed to statistically determine the number of subsegments required for segmentectomy. The cutting margin width for wedge resection and segmentectomy was recorded, as well as the specific subsegments and their quantities removed during lung segmentectomy were documented. In wedge resection, segmentectomy, and lobectomy, the sizes of pulmonary nodules were (1.08±0.29) cm, (1.31±0.34) cm and (1.50±0.35) cm, respectively, while the depth of the nodules (OA values) was 6.05 (5.26, 6.85) cm, 4.43 (3.27, 5.43) cm and 3.04 (1.80, 4.18) cm for each procedure, showing a progressive increasing trend (P<0.001). The median resection margin width obtained from segmentectomy was 2.50 (1.50, 3.00) cm, significantly greater than the 1.50 (1.15, 2.00) cm from wedge resection (P<0.001). In wedge resections, cases where AB value >2 cm demonstrated a higher proportion of cases with resection margins less than 2 cm compared to those with margins greater than 2 cm (29.03% vs 12.90%, P=0.019). When utilizing the size of the nodule as the criterion for resection margin, the instances with AB value >2 cm continued to show a higher proportion in the ratio of margin distance to tumor size less than 1 (37.50% vs 17.39%, P=0.009). The median number of subsegments for segmentectomy was three, whereas lobectomy cases requiring segmentectomy involved five subsegments (P<0.001). The selection of the surgical approach for lung resection is influenced by both the size and depth of pulmonary nodules. This study first confirms that larger portions of lung tissue must be removed for nodules that are deeper and larger to achieve a safe margin. A distance of ≤2 cm from the inner edge of the pulmonary nodule to the nearest pleura may be the ideal indication for performing wedge resection.

First Uniportal VATS Sleeve Lobectomy Case in Turkey

Introduction: In recent years, VATS (Video-assisted thoracic surgery) has become the gold standard approach in the surgical treatment of early-stage Non-small Cell Lung Cancer. In August 2022, we presented the first case of Uniportal VATS right bronchial sleeve upper lobectomy for right main bronchial invasion, which was successfully managed following oncologic principles and reported in our country. Case: A patient who had been in remission for five years with a diagnosis of laryngeal carcinoma complained of cough. Computed thoracic tomography showed hilar peribronchial thickening and an endobronchial lesion extending from the right upper lobe bronchus to the main bronchus, almost completely obstructing the upper lobe bronchus. Bronchoscopic biopsy was reported as squamous cell carcinoma.The thorax was entered through an approximately 3 cm incision in the right fifth intercostal space. Firstly, the right upper lobe pulmonary arteries and superior pulmonary vein were dissected and cut. The main bronchus was divided until the intermediate bronchus. With the help of endoscissor, the main and intermediate bronchus were incised with appropriate surgical margins, and the lobectomy material was removed.The mediastinal pleura was opened, and lymph nodes 7, 9, 10 were dissected. Before anastomosis, the azygos vein was turned and fixed to the chest wall with a tying suture, and the azygos vein was removed from the anastomosis line, and appropriate exposure was provided. One suture was passed through the lateral cartilage from the inside out, and the needle was fixed to the posterior pleura. Membranous and cartilage parts were continuously anastomosed with double-needle 3/0 prolene suture at 2-3 mm intervals. Pathological evaluation was reported as squamous cell carcinoma, hilar 1/11 lymph node metastasis, and negative surgical margin. Conclusion: Adhering to oncologic principles, sleeve resections, which are difficult even with the currently known open techniques, can be performed effectively and safely with uniportal VATS in experienced centers

Anesthetic technique and postoperative pulmonary complications (PPC) after Video Assisted Thoracic (VATS) lobectomy: A retrospective observational cohort study.

Thoracic surgery is associated with an 8-10% incidence of postoperative pulmonary complications (PPCs). Introduction of minimally invasive Video-assisted thoracoscopic surgery (VATS) aimed to reduce pain related and pulmonary complications. However, PPCs remain a common cause of morbidity after VATS. The American College of Surgeons National Surgical Quality Improvement Program database was searched for VATS lobectomy cases from 2017 to 2021 with General Anesthesia (GA) as the primary anesthetic technique. Cases were stratified into four groups-GA alone, GA+local, GA+Regional and GA+Epidural. Generalized linear regression models were used to examine whether PPCs differ by anesthetic technique, controlling for morbidity risk factors. The study's primary outcome was the occurrence of any PPC (pneumonia, reintubation or prolonged mechanical ventilation). The secondary outcome was length of hospital stay (LOS). A total of 15,084 VATS lobectomy cases were identified and 14,477 cases met inclusion criteria. The PPC rate was between 3.5-5.2%. There was no statistically significant difference in the odds of PPCs across the groups. Compared to the GA alone group, the regional and local group had significantly shorter LOS (9.1% and 5.5%, respectively, both ps < .001), whereas the epidural group had significantly longer LOS (18%, p < .001). Our analysis suggests that the addition of regional or local anesthesia is associated with shorter LOS after VATS lobectomy. However, these techniques were not associated with lower PPC incidence. Future randomized controlled trials could help to elucidate the best anesthetic technique to reduce pain and enhance recovery.

A newly developed surgeon‐controlled suction device in robotic‐assisted thoracoscopic surgery

AbstractIntroductionAssistant surgeons usually clean the surgical field with a suction cannula in robotic‐assisted surgery. This manipulation requires skill and experience to avoid interfering with the operation of the console surgeon. Recently, we created a new suction device that a console surgeon can manipulate with the robotic arms.Materials and Surgical TechniqueA small metal suction tip with as a lumen and small side pores for suction and can be connected to a silicone tube connected to wall suction. The tip of the silicone tube can be grasped with robotic forceps and used for organ retraction as well as suction. The suction device has been used in eight lung lobectomy cases and four lung segmentectomy cases to date. There were no major difficulties related to the new suction device except for metal tip disconnection and blood clots clogging.DiscussionOur newly developed surgeon‐controlled suction device is inexpensive, easy to handle, and useful for suction, blunt dissection, and organ retraction in robotic‐assisted thoracoscopic surgery, especially when performing lymph node dissection.

Outcomes of CT-Guided Deeper Localization Technique for Superficial Pulmonary Nodules.

The possibility of coil dislocation in computed tomography (CT)-guided microcoil localization of superficial pulmonary nodules is relatively high. The aim of the study is to investigate the outcomes of deeper localization technique during CT-guided microcoil localization of superficial pulmonary nodules before video-assisted thoracoscopic surgery (VATS). Fifty-seven identified superficial pulmonary nodules (nodule-pleural distance ≤ 1 cm on CT image) from 51 consecutive patients underwent CT-guided microcoil localization, and subsequent VATSs were included. The rate of technical success, complications, and excised lung volume were compared between deeper localization technique group and conventional localization technique group. The technical success rate of the localization procedure was 100% (25/25) in the deeper localization group and 81.3% (26/32) in the conventional localization group (p = 0.030). Excluding one case of lobectomy, the excised lung volume in the deeper localization group and the conventional localization group was 39.3 ± 23.5 and 37.2 ± 16.2 cm3, respectively (p = 0.684). The incidence of pneumothorax was similar between the deeper localization group and the conventional localization group (24.0 vs. 21.9%, respectively, p = 0.850). The incidence of intrapulmonary hemorrhage in the deeper localization group was higher (16.0%) than that in the conventional localization group (6.3%), but the difference was not statistically significant (p = 0.388). CT-guided microcoil localization of superficial pulmonary nodules prior to VATS using a deeper localization technique is feasible. Deeper localization technique reduced the occurrence of dislocation but did not increase excised lung volume.

A Case of Total Arch Replacement and Lung Lobectomy for Infected Aortic Aneurysm Ruptured Into Lung

We report an extremely rare case of a 77-year-old woman who underwent total arch replacement and left upper pulmonary lobectomy for an E. coli-infected aortic aneurysm that ruptured into the lung, which was first suspected to be lung cancer. On the 6th postoperative day, she weaned off the respirator. However, because of interstitial pneumonia and disseminated intravascular coagulation (DIC), she was put to sleep 38 days postoperatively without leakage at the artificial vascular anastomosis or bronchopleural fistula.

Robot-assisted thoracoscopic right upper lobectomy with displaced B3 and absence of minor fissure: a case report.

B3 downward-shifting is a rare bronchial anomaly characterized by abnormal pulmonary arteries associated with downward displacement of B3 and complete fusion between the right upper and middle lobes. We report a case of robot-assisted thoracoscopic right upper lobectomy in a patient with lung cancer with B3 downward-shifting. An 81-year-old male was diagnosed with non-small cell lung cancer in S3 of the right upper lung. Preoperative three-dimensional computed tomography angiography revealed a B3 bronchus derived from the middle lobe bronchus and an anterior segmental pulmonary artery variation. Robot-assisted thoracoscopic surgery right upper lobectomy with ND2a-1 was performed via four-port incisions and an assist incision. No interlobar fissure was observed between the right upper and middle lobes. After dissecting B1+2, the displaced B3 root was dissected. The displaced A3a was difficult to dissect because of an extremely severe complete fissure. Therefore, we dissected the bronchus preceding from the cranial side. To confirm a minor fissure, indocyanine green was administered intravenously, and the interlobar boundary was identified as the line separating the dark and green lung parenchyma. The boundary was divided using mechanical staples. No surgical complications occurred. Using three-dimensional reconstruction imaging and systemic indocyanine green administration, we successfully performed a right upper lobectomy through robot-assisted thoracic surgery.

Learning curve of trans-areola single-site endoscopic thyroidectomy in a high-volume center: A CUSUM-based assessment.

Limited attempts have been made in trans-areola single-site endoscopic thyroidectomy (TASSET) due to technical challenges and the lengthy time for proficiency. This study aimed to define the learning curve of TASSET and to describe improvements in operative performance over time. Based on 222 consecutive TASSET procedures, the learning curve was established according to the operation time by using cumulative sum analysis (CUSUM). The end-point of learning curve was defined as the number of cases necessitated to reach the initial surgical proficiency stage. The demographic information, surgical and oncological outcomes, surgical stress, and postoperative complications were also analyzed. There were 70 cases of simple lobectomy for benign nodules and 152 cases of lobectomy with central neck dissection (CND) for malignancy. The mean operative time was 106.54 ± 38.07 min (range: 46-274 min). The learning curve identified two phases: the skill acquisition phase (Case 1-Case 41) and the proficiency phase (Case 42-Case 222). There were no significant differences in demographic information, drainage amount and duration, oncological outcomes, and postoperative complications between the two phases (p > 0.05). Both operation time and postoperative hospitalization decreased significantly in Phase 2 (154.63 ± 52.21 vs. 95.64 ± 22.96 min, p < 0.001; 4.12 ± 0.93 vs. 3.65 ± 0.63 days, p < 0.001). Additionally, the mean variations of surgical stress factors (C-reactive protein and erythrocyte sedimentation rate) decreased significantly as the phase progress. The case number required for proficiency phase in benign and malignant tumor were 18 and 33, respectively, and lymph node resection posed a significant impact on the endpoint of the learning curve (p < 0.001). Meanwhile, the size of nodule showed no significant impact (p = 0.622). For right-handed surgeons, 16 cases and 25 cases were required for technical competence in left-sided and right-sided lesions, respectively, and no significant difference reached (p = 0.266). TASSET has demonstrated safe and technically feasible with comparable oncological outcomes. Experience of 41 cases was required for surgical competence and proficiency. The initial learning stage could be more quickly adopted by high-volume thyroid surgeons with standardized procedures.

Minimally invasive sleeve lobectomy for centrally located lung cancer: A real-world study with propensity-score matching.

The safety, feasibility, and prognosis of sleeve lobectomy by minimally invasive surgery (MIS) remain to be validated. The purpose of this study was to investigate outcomes in real-world patients receiving minimally invasive sleeve lobectomy in a balanced large cohort. Between January 2013 and December 2018, 578 consecutive patients undergoing sleeve resection at a high-volume center were retrospectively analyzed. Surgical and oncologic outcomes were compared between MIS and thoracotomy patients after propensity-score matching (PSM). MIS sleeve lobectomy was increasingly used as a time-trend in real-world. Before PSM, the MIS group had smaller tumor size, more T2-stage cases, and more right upper lobe sleeve lobectomies compared to the Open group. After 1:4 PSM by patient demographics and tumoral characteristics, 100 cases of MIS and 338 cases of Open sleeve lobectomy were further analyzed. Although median operation time was longer in the MIS group than in the Open group (170.5 minutes vs.149.5 minutes, P < 0.001), patients in MIS group had significantly less estimated intraoperative blood loss (100 ml vs. 200 ml, P = 0.003), shorter drainage duration (5 days vs. 6 days, P = 0.027) and less amount of drainage (1280 ml vs. 1640 ml, P < 0.001) after surgery. Complete resection rate, combined angioplasty, number of dissected lymph nodes, post-operative length of stay, postoperative morbidity and mortality rate, and application of adjuvant therapy were similar between the two matched groups. Conversion to open thoracotomy was necessary in 13.6% patients, but with similar perioperative outcomes compared to Open cases except for longer operation time. More lower lobe sleeve lobectomies were accomplished via robot-assisted thoracoscopic surgery than via video-assisted thoracoscopic surgery (40.0% vs. 12.0%, P = 0.017) in MIS patients. Five-year overall survivals (MIS vs. Open: 72.7% vs. 64.4%, P = 0.156) and five-year progression-free survivals (MIS vs. Open: 49.2% vs. 50.5%, P = 0.605) were similar between the two matched groups. MIS sleeve lobectomy is associated with similar or even better perioperative results and oncologic outcomes to open thoracotomy. Conversion to thoracotomy does not compromise perioperative outcomes. Robot surgery may be preferable for more complex sleeve resections.

Left middle lobectomy in a patient with Kartagener's syndrome.

The middle lobe is usually a part of the right lung as it is tri-lobar in normal anatomy. In patients with Kartagener's syndrome, the middle lobe belongs to the left lung due to situs inversus. They are prone to develop bronchiectasis due to ciliary dyskinesia and bronchial anatomy of the middle lobe. We hereby report an interesting case of left middle lobectomy done in a patient with Kartagener's syndrome with bronchiectasis.

The learning curve for single-port transaxillary robotic thyroidectomy (SP-TART): experience through initial 50 cases of lobectomy.

The new da Vinci® single-port (SP) robotic system, which utilizes a smaller incision and work space compared to the previous versions, is suitable for thyroidectomy. This study aimed to evaluate the learning curve for SP transaxillary robotic thyroidectomy (SP-TART) in a single-center. Fifty consecutive patients who underwent SP-TART between October 2021 and April 2022 in Seoul St. Mary's Hospital in Seoul, Korea, were included in this retrospective analysis. We examined the clinicopathological characteristics and short-term surgical outcomes and assessed the learning curve for SP-TART using cumulative summation analysis. The mean operation time was 57.8 ± 14.1min, and the mean tumor size was 1.0 ± 0.7 (range, 0.3-3.7) cm. The patients were discharged approximately 2days after surgery, and only two (4%) patients developed postoperative complications, including drainage-site bleeding and surgical site infection. Risk factors for long operation time were thyroiditis, amount of blood loss, and lymph node metastasis. The learning curve for SP-TART was 20 cases for the experienced robotic surgeon. SP-TART is technically feasible and safe with a short incision length and short operation time. It is a valuable alternative operative option with good surgical outcomes and outstanding cosmetic results.

Pulmonary Open, Robotic, and Thoracoscopic Lobectomy study: Outcomes and risk factors of conversion during minimally invasive lobectomy

ObjectiveConversion to thoracotomy continues to be a concern during minimally invasive lobectomy. The aim of this propensity-matched cohort study is to analyze the outcomes and risk factors of intraoperative conversion during video-assisted thoracoscopic surgery (VATS) and robotic lobectomy (RL). MethodsData from consecutive lobectomy cases performed for clinical stage IA to IIIA lung cancer was retrospectively collected from the Pulmonary Open, Robotic, and Thoracoscopic Lobectomy study consortium of 21 institutions from 2011 to 2019. The propensity-score method of inverse-probability of treatment weighting was used to balance the baseline characteristics across surgical approaches. Univariate logistic regression models were applied to test risk factors for conversion. Multivariable logistic regression analysis was conducted using a stepwise model selection method. ResultsSeven thousand two hundred sixteen patients undergoing lobectomy were identified: RL (n = 2968), VATS (n = 2831), and open lobectomy (n = 1417). RL had lower conversion rate compared with VATS (3.6% vs 12.9%; P < .0001). In the multivariable regression model, tumor size and neoadjuvant therapy were the most significant risk factors for conversion, followed by prior cardiac surgery, congestive heart failure, chronic obstructive pulmonary disease, VATS approach, male gender, body mass index, and forced expiratory volume in 1 minute. Conversions for anatomical reasons were more common in VATS than RL (66.6% vs 45.6%; P = .0002); however, conversions for vascular reasons were more common in RL than VATS (24.8% vs 14%; P = .01). The rate of emergency conversions was comparable between RL and VATS (0.5% vs 0.7%; P = .25) with no intraoperative mortalities. ConclusionsConverted minimally invasive lobectomies were not associated with worse perioperative mortality compared with open lobectomy. Compared with VATS lobectomy, RL is associated with a lower probability of conversion in this propensity-score matched cohort study.

Should Thyroid Lobectomy Be Performed as a Day-Case Procedure? A Single-Centre Retrospective Audit.

Introduction The British Association of Endocrine and Thyroid Surgeons (BAETS) published guidance in 2012 advising against day-case thyroid lobectomy due to the unpredictable risk of post-operative haematoma. Due to the increasing pressures the National Health Service (NHS) faces, a position statement was released by BAETS in 2020 highlighting their support of day-case thyroid lobectomy in specific low-risk cases with the introduction of appropriate local protocols. Objective We aimed to assess post-operative complications of thyroid lobectomy at University Hospitals Bristol and Weston NHS Trust (UHBW), a tertiary centre for Otolaryngology, to consider the feasibility and safety of day-case surgery in our unit. Methods We conducted a retrospective audit of 140 elective thyroid lobectomy cases identified in the period of January 2017 to December 2018 at UHBW. Inclusion criteria included no previous thyroid surgery or major head and neck surgery, elective thyroid lobectomy procedure only, and surgery performed at UHBW by otolaryngology or maxillofacial teams. Exclusion criteria included emergency hemithyroidectomy; hemithyroidectomy as part of another procedure; and completion thyroidectomy. Results A total of 140 elective thyroid lobectomy procedures were performed between January 2017 and December 2018. Of them, 125 cases met inclusion criteria, and 15 cases were excluded: two emergency hemithyroidectomy, three incorrect coding, four hemithyroidectomy as part of another head and neck procedure, and six completion thyroidectomy. Mean age was 51.9 years (range: 20-88 years), with 30 (24.0%) male cases and 95 (76.0%) female cases. Mean in-patient stay was 1.4 days (range: 0-19 days), and mean hours in hospital were 34 hours. Two (1.6%) cases were discharged on the same day of their operation. Post-operative complications included five (4%) cases of post-operative haematoma, four (3.2%) cases of unilateral vocal cord palsy, one (0.8%) case of pneumonia, and three (2.4%) cases of wound infections. From those cases that developed post-operative haematoma, 80% (n=4/5) developed less than 24 hours after the procedure. One (20%) case of post-operative haematoma developed on day 6 after their procedure and required readmission for re-operation. Conclusion The unpredictable nature of post-operative haematoma poses a significant risk to patients and medicolegal implications. Our findings suggest that there were no predictable risk factors amongst our patient cohort and therefore day-case thyroid lobectomy should be avoided. Further research is required to identify low-risk patients who could benefit from day-case surgery.

Impact of cost-awareness education and surgeon-led positive deviance on intraoperative costs of thoracoscopic lobectomy

ObjectiveDisposable instrument use during video-assisted thoracoscopic lobectomy is a significant driver of cost. The purpose of the study was to measure the effect of increasing surgeon cost awareness via successive “value improvement initiatives” on instrument costs. MethodsWe prospectively collected disposable instrument use data for all video-assisted thoracoscopic lobectomies performed by 5 Board-certified thoracic surgeons over 4 successive time periods: Period 1: control group of consecutive video-assisted thoracoscopic lobectomies before interventions; Period 2: video-assisted thoracoscopic lobectomies after displaying disposables price list in operating room; Period 3: video-assisted thoracoscopic lobectomies after educational presentation outlining disposable instrument price differences; Period 4: video-assisted thoracoscopic lobectomies after surgeon self-assessment with peer comparison of cost data from Period 3 and positive deviance seminar identifying the lowest-cost surgeon to lead discussion of optimal cost-reduction strategies. Instrument use and costs were compared among the 4 groups using the Kruskal–Wallis test. ResultsA total of 373 lobectomy cases were analyzed. Compared with Period 1, median stapler-related and total disposable costs for video-assisted thoracoscopic lobectomy cases decreased after successive value improvement initiatives, with lowest costs in Period 4 (P < .0001). Multiple linear regression analysis demonstrated per lobectomy disposables cost reduction of $397.53 in Period 4, after controlling for surgeon and lobe (P < .0001). Operating room time was reduced after successive value improvement initiatives (P < .0001). ConclusionsCost awareness and surgeon engagement activities were associated with sustained cost reduction for video-assisted thoracoscopic lobectomies. Surgeon self-assessment, peer comparison, and positive deviance seminar were associated with the largest cost reduction. Significant hospital cost-savings may be realized with surgeon-led value improvement initiatives.

A universal incision for robot-assisted thoracic surgery.

ObjectiveThis paper aimed to design and explore the versatility of the incision for the robot-assisted thoracic surgery.MethodsThe concept of universal incision was designed and put forward. The clinical data of 342 cases of robot-assisted thoracic surgery were summarized, including sex, age, clinical diagnosis, operative method, operative time, conversion to thoracotomy, intraoperative blood loss, number of lymph node dissections, postoperative hospital stays, postoperative pathology, and postoperative complications of the patients.ResultsThe 342 cases of robot-assisted surgery included 178 pulmonary surgery cases (94 lobectomy cases, 75 segmentectomy cases, 6 wedge resection cases, and 3 sleeve lobectomy cases), 112 esophageal surgery cases (107 McKeown approach cases and 5 esophageal leiomyoma resection cases), and 52 mediastinal tumor cases (42 anterior mediastinum cases and 10 posterior mediastinum cases). Among these, two cases were converted to thoracotomy (both esophageal cases), and the rest were successful with no massive intraoperative bleeding and no perioperative death.ConclusionThe universal incision of robot-assisted thoracic surgery is safe and feasible and is suitable for most cases of thoracic surgery.
