Is Epidural Analgesia Necessary after Video-Assisted Thoracoscopic Lobectomy?

Most studies have shown that thoracic epidural analgesia reduces postoperative pain, but it carries potential risks. Recently, video-assisted thoracoscopic surgery has become an established technique that causes minimal postoperative pain. This report shows that thoracic epidural analgesia is not always necessary after video-assisted thoracoscopic lobectomy. From January to December 2007, 30 consecutive patients who underwent video-assisted thoracoscopic lobectomy were examined retrospectively. We analyzed the necessity for routine thoracic epidural analgesia. The continuous subcutaneous analgesia catheter for morphine (2 mg in 48 h) was removed from 15 patients on postoperative day 1, and from the other 15 on day 2. We administered loxoprofen sodium hydrate, diclofenac sodium suppository, pentazocine hydrochloride, and mexiletine hydrochloride for postoperative analgesia, as needed. The mean pain score was no more than 1.0. The maximum score was 3.0 on day 0, and 2.0 on day 14; subsequently, no pain score exceeded 2.0. The postoperative hospital stay was 8.7 ± 0.8 days. All patients made uneventful postoperative recoveries. There is no need for thoracic epidural analgesia after every video-assisted thoracoscopic lobectomy because our patients recovered with no serious complication. Less invasive surgical approaches should require simpler postoperative pain management.

Thoracoscopic Rib Resection Using a Gigli Saw

When a conventional approach is used to perform a rib resection, a skin incision longer than the rib to be resected must be made. As a result, a conventional rib resection leaves a rather large and esthetically unfavorable scar. After considering pain management, esthetics, and quality of life, we devised a new technique for thoracoscopic rib resection that uses a Gigli saw. This new technique was performed on an overweight woman with a solitary metastatic bone tumor of the right eighth rib, whose case is described herein. The patient's postoperative course was satisfactory. Since this technique does not require a long skin incision, pain management and aesthetic results are improved compared with conventional techniques.

Video-assisted thoracoscopic surgery for diagnosis, staging, and management of lung cancer with suspected mediastinal lymphadenopathy

The aim of this report was to evaluate the effectiveness of video-assisted thoracoscopic surgery (VATS) in staging, diagnosis, and treatment of lung cancer. Fifty-two patients were scheduled for mediastinal lymph node VATS biopsy at the Oncologic Thoracic Surgery Department of the National Cancer Institute in Milan. Fifty patients underwent lymph nodal thoracoscopic biopsy (96%), whereas for the other 2 patients, histologic diagnosis was done by pleural metastatic nodule thoracoscopic biopsy (4%). We performed 17 lymph nodal biopsies in level 5 (33%), 14 in level 6 (27%), 12 in level 7 (23%), and 7 in level 8 (13%). No postoperative complications were observed, and 19 subjects (36%) underwent open lung resection. The histologic diagnosis was adenocarcinoma in 25 cases (48%), epidermoid carcinoma in 14 (27%), microcytoma in 9 (17%), and giant-cell lung carcinoma in 4 (8%); 10 patients were at stage I (19%), 9 at stage II (17%), 31 at stage III (60%), and 2 at stage IV (4%). The use of VATS allowed diagnosis of the suspected involved mediastinal lymph nodes in lung cancer patients and obviated the need for painful thoracotomy, enabling accurate staging and thus selection of the optimal treatment.

Video-assisted thoracic surgery: has technology found its place?

BACKGROUND

Since the introduction of minimally invasive surgical techniques in thoracic surgery in 1990, video-assisted thoracic surgery (VATS) has become the approach for many thoracic operations. The role of VATS has slowly evolved but has not been clearly defined. To better understand the role of VATS, we undertook a survey of practicing thoracic surgeons.

METHODS

A questionnaire was sent to members of the General Thoracic Surgery Club asking the role of VATS in their practice and their opinions regarding appropriate applications, advantages, and limitations of the approach.

RESULTS

Two hundred of the 229 members (87.3%) responded to the questionnaire. In this largely academic (66.3%) group of thoracic surgeons, 72% of whom had more than 10 years experience in general thoracic surgery, VATS was the preferred approach (> 50% response) for the management of pleural disease, lung biopsy, recurrent pneumothorax, and sympathectomy. A majority of respondents thought that VATS was an acceptable approach for the diagnosis of the indeterminate pulmonary nodule and of anterior and posterior mediastinal masses, and for the management of early empyema, clotted hemothoraces, secondary pneumothorax, limited lung cancer treatment, and benign esophageal disease. Video-assisted thoracic surgery was thought to be unacceptable or investigational by a majority for thymectomy, lobectomy, and lung volume reduction operations. Video-assisted thoracic surgery still represents only a small portion of the thoracic procedures performed, but there is a gradual increase in its rate of use, although 38.1% expressed concern regarding overuse. The main limitation was thought to be in the management of oncologic disease.

CONCLUSIONS

It appears that VATS is a valuable addition to the practice of thoracic surgery, but significant limitations exist. Although there appear to be many specific indications defined, there is still a significant evolutionary component.
