Subxiphoid-subcostal versus transthoracic thoracoscopic thymectomy: A safe and feasible approach.

ABSTRACT:

Objective

Subxiphoid-subcostal thoracoscopic thymectomy (ST) is an emerging alternative to transthoracic thoracoscopic thymectomy. Potential advantages of ST are the avoidance of intercostal incisions and visualization of both phrenic nerves in their entirety. We describe our experience with ST and compare our results to our previous experience with transthoracic thoracoscopic thymectomy.

Methods

We conducted an institutional review board-exempt retrospective review of all patients who had a minimally invasive thymectomy from August 2008 to October 2021. We excluded patients with a previous sternotomy or radiological evidence of invasion into major vasculature. The ST approach involved 1 subxiphoid port for initial access, 2 subcostal ports on each side, and carbon dioxide insufflation. We used descriptive and comparative statistics on demographic, operative, and postoperative data.

Results

We performed ST in 40 patients and transthoracic thoracoscopic thymectomy in 16 patients. The median age was higher in the ST group (58 years vs 34 years; P = .02). Operative data showed no significant differences in operative times, blood loss, or tumor characteristics. In the ST group, we had 2 emergency conversions for bleeding; 1 ministernotomy, and 1 sternotomy. Postoperative data showed that the ST group had fewer days with a chest tube (1 day vs 2.5 days; P = .02). There were no differences in median length of stay, tumor characteristics, final margins, major complication rate, and opioid requirements between the groups. There has been no incidence of diaphragmatic hernia and no phrenic nerve injuries or mortality in either group.

Conclusions

ST is safe and has similar outcomes compared with transthoracic thoracoscopic thymectomy.

Project description:BackgroundApproaches of thoracoscopic thymectomy for myasthenia gravis (MG) are debatable. The subxiphoid approach is widely utilized recent years for its better visualization of the anterior mediastinum. In the present study, we compared perioperative outcomes and mid-term effects of the extended thymectomy for MG between the subxiphoid approach and the routine right-thoracic approach.MethodsOne hundred and thirty-one MG patients treated with thoracoscopic extended thymectomy were analyzed. Among them, 68 patients were operated on via the subxiphoid approach and the other 63 via the conventional right-side unilateral approach. The patient outcomes were retrospectively reviewed and evaluated. Mid-term clinical outcome was assessed according to the classification system proposed by the Myasthenia Gravis Foundation of America (MGFA). Clinical efficacy and variables influencing outcome were evaluated by the Kaplan-Meier method and Cox proportional hazards regression analysis.ResultsCompared with the right thoracic approach, the duration of the procedure via the subxiphoid approach was significantly shorter (P=0.035), the rates of total thymectomy were higher (P=0.028), and the pain scores on postoperative days 1, 3, and 7 were significantly lower (P<0.001, P<0.001, and P=0.03, respectively). A total of 112 patients with MG were followed up. The subxiphoid approach group reported higher rates of complete stable remission (CSR) and effective treatment of MG, although these differences were not statistically significant (Z=-0.484, P=0.627). By multivariate Cox proportional hazards modes analysis, the chance of CSR was significantly increased when age <40 (OR: 2.623, 95% CI: 1.150-5.983, P=0.022), non-thymomatous MG (OR: 1.078, 95% CI: 1.101-3.316, P=0.021) and MGFA clinical classification (OR: 2.024, 95%:1.164-3.523, P=0.013).ConclusionsThe subxiphoid approach has shorter operation time, higher rates of total thymectomy and better quality of life compared with the lateral thoracoscopic approach. Preoperative age, pathological diagnoses and MGFA Clinical Classification are the independent risk factors for non-complete stable remission (NCSR) after thymectomy.

Project description:Introduction: Robotic and thoracoscopic surgery are being increasingly adopted as minimally invasive alternatives to open sternotomy for complete thymectomy. The superior maneuverability range and three-dimensional magnified vision are potential ergonomical advantages of robotic surgery. To compare the ergonomic characteristics of robotic versus thoracoscopic thymectomy, a previously developed scoring system based on impartial findings was employed. The relationship between ergonomic scores and perioperative endpoints was also analyzed. Methods: Perioperative data of patients undergoing robotic or thoracoscopic complete thymectomy between January 2014 and December 2022 at three institutions were retrospectively retrieved. Surgical procedures were divided into four standardized surgical steps: lower-horns, upper-horns, thymic veins and peri-thymic fat dissection. Three ergonomic domains including maneuverability, exposure and instrumentation were scored as excellent(score-3), satisfactory(score-2) and unsatisfactory(score-1) by three independent reviewers. Propensity score matching (2:1) was performed, including anterior mediastinal tumors only. The primary endpoint was the total maneuverability score. Secondary endpoints included the other ergonomic domain scores, intraoperative adverse events, conversion to sternotomy, operative time, post-operative complications and residual disease. Results: A total of 68 robotic and 34 thoracoscopic thymectomies were included after propensity score matching. The robotic group had a higher total maneuverability score (p = 0.039), particularly in the peri-thymic fat dissection (p = 0.003) and peri-thymic fat exposure score (p = 0.027). Moreover, the robotic group had lower intraoperative adverse events (p = 0.02). No differences were found in residual disease. Conclusions: Robotic thymectomy has shown better ergonomic maneuverability compared to thoracoscopy, leading to fewer intraoperative adverse events and comparable early oncological results.

Project description:BackgroundMinimally invasive surgery has been used to treat anterior mediastinal tumors. This study sought to describe a single team's experience of uniport subxiphoid mediastinal surgery using a modified sternum retractor.MethodsPatients who underwent uniport subxiphoid video-assisted thoracoscopic surgery (USVATS) or unilateral video-assisted thoracoscopic surgery (LVATS) from September 2018 to December 2021 were retrospectively enrolled in this study. A 5-cm vertical incision approximately 1-cm caudal to the xiphoid process was usually made followed by the installment of a modified retractor, which was able to raise the sternum by 6-8 cm. Next, the USVATS was performed. In the unilateral group, 3 1-cm incisions were usually made, among which, 2 are made in the 2nd or 3rd and 5th intercostal anterior axillary line, and the 3rd was made in the 5th intercostal midclavicular line. In some instances, an additional subxiphoid incision was made to remove the large tumors. All the clinical and perioperative data, including the prospectively recorded visual analogue scale (VAS) score, were analyzed.ResultsIn total, 16 patients who underwent USVATS and 28 patients who underwent LVATS were enrolled in this study. With the exception of tumor size (USVATS 7.9±1.6 cm vs. LVATS 5.1±2.4 cm, P<0.001), the baseline data of the patients in the 2 groups were comparative. Blood loss in surgery, conversion, draining duration, postoperative stay, postoperative complications, pathology and tumor invasion were similar between the 2 groups. Although the operation time was significantly longer in the USVATS group than the LVATS group (115±19 vs. 83±30 min, P<0.001), the VAS score at 1st postoperative day (1.9±1.1 vs. 3.1±1.1, P<0.001) and moderate pain level (a VAS score >3) (6.3% vs. 32.1%, P=0.049) were better in the USVATS group than the LVATS group.ConclusionsUniport subxiphoid mediastinal surgery is a feasible and safe procedure, especially for large tumors. Our modified sternum retractor is especially helpful during uniport subxiphoid surgery. Compared to lateral thoracic surgery, this approach has the advantages of less injury and lower postoperative pain, which may lead to a faster recovery. However, its long-term follow-up outcomes need to be observed.
