Purpose: Bronchial sleeve resection with complete pulmonary preservation (BSRCPP) is a classic surgical method for the treatment of benign or low-grade bronchial tumors. For elderly patients and patients with poor cardiopulmonary function, BSRCPP is particularly advantageous because some of these patients may not tolerate lobectomy or pneumonectomy. We retrospectively reviewed the clinical data of 20 patients who underwent BSRCPP during the past 7 years. This report presents the experience with BSRCPP in our department.
Patients and Methods: We collected the data of 20 patients who underwent BSRCPP. Of these 20 patients, 17 underwent thoracotomy and 3 underwent video-assisted thoracoscopic surgery (VATS). The study cohort comprised 7 male and 13 female patients with an average age of 44 years (range, 4– 71 years). All patients underwent a systematic preoperative examination to confirm the surgical indications and methods. Regular follow-up was conducted after the operation.
Results: All patients survived and remained clinically well. Two of the 20 patients (10%) were re-admitted to the hospital because of pulmonary air leakage, which was resolved after thoracic drainage. No patients developed tumor recurrence.
Conclusion: BSRCPP may be an effective treatment for selected patients with bronchial tumors. Notably, however, many technical key points require improvement, especially in VATS. Therefore, thoracoscopic minimally invasive treatment requires more practice and exploration.

Keywords: sleeve lobectomy, BSRCPP, VATS, thoracotomy

Introduction

As a special type of bronchial sleeve resection, bronchial sleeve resection with complete pulmonary preservation (BSRCPP) retains healthy lung tissue with radical tumor resection. Because of the outstanding curative effect of BSRCPP (minimal invasiveness of treatment and maximal preservation of lung function), this procedure has been applied to the treatment of both benign, indolent bronchial malignancies and bronchial stenosis.1,2 In 2019, we performed 14,465 surgical procedures for the treatment of lung cancer, and our department has become an ultra-high-volume thoracic surgery center. This situation has been reported by our counterparts.3 We reviewed the evolution of BSRCPP in our department during the past 7 years, focusing on the indications for and clinical outcomes of this special surgical technique as well as the feasibility of its application by video-assisted thoracoscopic surgery (VATS).

Patients and Methods

This retrospective analysis was performed at a single institution. The clinical data of 20 patients who underwent BSRCPP during the past 7 years were collected from the medical records. Chest computed tomography and telephone follow-ups were performed every half year in all patients to assess the prognosis and survival. This study was approved by Shanghai Pulmonary Hospital, Tongji University and was performed in accordance with the guidelines of the Helsinki Declaration of 1975, revised in 1983. All participants provided written informed consent. We confirm that a parent or legal guardian of patients under the age of 18 years provided informed consent.

Surgical Techniques

The patients were placed in the lateral decubitus position. After general anesthesia and endotracheal intubation, a posterolateral incision was made at the fourth or fifth intercostal space (ICS). Double-portal VATS involved the placement of one 1-cm camera port at the seventh ICS along the posterior axillary line and performance of one 3-cm utility incision at the fourth ICS along the anterior axillary line. First, we examined whether any adhesion was present in the thoracic cavity, loosened the inferior pulmonary ligament, and performed hilar release with a C-shaped incision in the pericardium at the bottom of the inferior pulmonary vein according to the tension of the anastomosis. The mediastinal pleura was then opened to expose the veins of the upper and lower lobes and the main trunk of the pulmonary artery. With the assistance of intraoperative bronchoscopy, we determined the boundary and scope of the tumor. After freeing the main bronchus and clearing the surrounding lymph nodes, the segments of the trachea containing tumor lesions were circularly resected. Proximal and distal margins of at least 0.5 cm were transected for frozen section examination to confirm a tumor-free status. In patients who underwent thoracotomy, end-to-end bronchial anastomosis was performed using 3–0 Vicryl interrupted sutures. In the three patients who underwent VATS, a running suture was applied using 3–0 Prolene (Figures 1–4). Finally, thoracic flushing was performed after careful hemostasis, and the lungs were pressurized to test for air leakage at the anastomosis site. We usually wrapped the bronchial anastomosis with pericardial fat, pleura, or pedicled intercostal muscles, and two chest tubes were placed for drainage. In Patient 15, because the tumor was located in the right main bronchus and was large in diameter, we performed carina reconstruction during BSRCPP. For sleeve resection of left main bronchus tumor, avoiding obstruction of aortic arch is the main problem to be solved. We fully dissociate the aortic arch and pull it up with a ribbon, leaving room for simple continuous suture, which is the main procedure and the challenging moment. As for the pairing of tracheal membrane and cartilage during the anastomosis, we believe that there is no special point. The most important thing is to ensure that there is no tension during the anastomosis and the bronchus cannot be twisted.

Results

Baseline Characteristics

The data of 20 patients who underwent BSRCPP from January 2013 to October 2019 were collected from the medical records. In the past 7 years, the total surgical volume in our department was 77,241, and the number of cases in this study accounted for 0.025%. Of these 20 patients, 17 underwent thoracotomy and 3 underwent VATS (Patients 4, 13, and 16). The patients’ mean age was 42.5 ± 16.0 years (range, 4–71 years). Nineteen patients had bronchial neoplasms, and one patient (Patient 5) developed a benign stricture after trauma. Fourteen patients were symptomatic, including cough in 11 patients, dyspnea in 1, fever in 1, and chest pain in 1. The neoplasms in the six asymptomatic patients were found during a routine checkup (Table 1).

Table 1 Characteristics of Patients

Preoperative Evaluations

Preoperative examinations of all patients included cardiac ultrasonography, pulmonary function tests, bronchoscopy, and chest enhanced computed tomography. Bone scans, brain magnetic resonance imaging, and positron emission tomography scans were performed to rule out metastasis in patients suspected to have malignant tumors. The preoperative evaluations were performed in an effort to confirm the following surgical indications: a benign or low-grade malignant endotracheal lesion with a small implantation base and no hilar or mediastinal lymph node metastasis. Bronchoscopic examination was a mandatory procedure for all patients before surgery because it can display clear airway conditions and is valuable for determining the location of bronchial lesions. Furthermore, a bronchoscopic biopsy was performed to confirm the presence of benign or low-grade malignant lesions. Although the biopsy result of Patient 4 was squamous cell carcinoma, the patient had an endotracheal pedicled tumor with a diameter of only 0.6 cm and a small base. Therefore, we performed BSRCPP under the assistance of VATS. On the first postoperative day, we routinely performed bedside bronchoscopy to observe the bronchial anastomosis and airway sputum accumulation and perform corresponding treatments.

Among the 20 patients who underwent bronchoscopy before surgery, the lung function tests in two patients (Patients 8 and 13) revealed pulmonary ventilation dysfunction, and the tumor occupied the tracheal cavity, leading to atelectasis. These two patients were treated with local ablation with high-frequency electrocoagulation (40 W), temporarily releasing the airway obstruction. After confirmation that the anesthetic cannula can be tolerated, we performed BSRCPP. Both of our patients underwent surgery after 7 days.

No patient died during the surgery, and the median length of hospital stay was 7.7 days (range, 4–21 days). Postoperative complications (pulmonary air leakage) occurred in two patients (Patients 3 and 11), both of whom were cured after thoracic drainage. No patients developed a bronchopleural fistula as confirmed by bronchoscopy. No patients developed atelectasis or anastomotic stenosis. All patients underwent rigorous postoperative computed tomography reviews and were still alive at the time of this writing. The postoperative pathologic examinations confirmed mucoepidermoid carcinoma (n = 6), adenoid cystic carcinoma (n = 3), squamous hyperplasia of the mucosal epithelium (n = 2), leiomyoma (n = 1), fibroid (n = 1), squamous carcinoma (n = 1), basal cell adenoma (n = 1), typical carcinoid (n = 1), pleomorphic adenoma (mixed tumor), epithelial-myoepithelial tumor (n = 1), and borderline tumor (n = 1). The median follow-up time was 44.3 months (range, 1–82 months).

Comment

In 1947, Sir Clement Price Thomas performed the first bronchial sleeve resection for a patient with a right main bronchus adenoma.4 Later, in 1959, Johnson and Jones retrospectively analyzed 98 bronchial sleeve resection procedures that were performed by their team, strongly confirming the feasibility and safety of sleeve lobectomy.5 However, few reports have described bronchial sleeve resection with pulmonary preservation. BSRCPP is used to treat central lung cancer that invades the main bronchus6–8 as well as benign or low-grade malignant bronchial lesions with normal anatomy of the bronchial tree. Surgical indications also include the absence of external bronchial dissemination, the absence of hilar mediastinal lymph node metastasis, and tumors limited to the mainstem bronchus or bronchus intermedius with negative margins.9–11 BSRCPP is especially suitable for elderly patients, patients with poor cardiopulmonary function, and patients who cannot tolerate massive resection. One of our patients had post-traumatic bronchial stenosis, and the remaining patients had bronchial benign or low-grade malignant tumors. With respect to essential surgical techniques, tension-free anastomosis is critical for a successful operation. Division of the inferior pulmonary ligament and peritracheal mobilization are common techniques used during the operation.2,12,13 Hilar release can also be conducted. In the present study, a C-shaped incision was performed in the pericardium at the bottom of the inferior pulmonary vein, which greatly reduced the anastomotic tension.

The main complications of BSRCPP, among which is bronchopleural fistula formation, will deteriorate patients’ quality of life.14–16 A negative resection margin and tension-free anastomosis are the key points for the prevention of a bronchopleural fistula. Postoperative anastomotic stenosis is also a common complication and is usually caused by twisting of the bronchus when the surgeon sutures the cutting edge. In our series, Patients 3 and 11 developed postoperative pulmonary air leakage, and both were discharged after thoracic drainage. No complications, including postoperative atelectasis and pneumonia, occurred in our patients. We performed continuous anastomosis combined with interrupted suturing. Some studies have focused on innovative techniques such as the “continuous suture dividing and equal suture tightening” method and hybrid suturing techniques.17,18

During the past 20 years, video-assisted thoracic bronchial sleeve lobectomy with bronchoplasty has undergone rapid development. This technique was historically considered a technically restricted area. It was not until 2002 that Santambrogio et al successfully performed the first VATS sleeve bronchoplasty for a low-grade mucoepidermoid carcinoma of the left lower lobar bronchus.19 VATS has the following advantages: clearer surgical vision, shared resources, decreased postoperative pain, and a shorter hospital stay.20–26 Our three patients underwent double-portal VATS, which is superior to the conventional tri-portal surgical approach. Double-portal VATS may be a minimally invasive alternative. Additionally, the creation of one utility port at the fourth ICS along the anterior axillary line can avoid interference of the pulmonary artery in the anastomosis.

This study has some limitations. Notably, it was a single-center retrospective study. The number of patients was small and the operation location was not uniform; therefore, it was impossible to design a prospective randomized study. However, increasingly more practical experiences are suggesting that patients’ quality of life is better if they are treated by BSRCPP than by standard resection. There are abundant reports on this technique and its prognosis.14,27–29 In conclusion, BSRCPP is a well-developed technology, but its operation with the assistance of VATS remains stringently demanding to surgeons.30–33
