Definition
A lung lobectomy is a surgical procedure involving the removal of one of the lobes of the lung. It is performed to excise localized disease, most commonly primary lung cancer, but also benign tumors, localized infections, or damaged lung tissue.
Overview
Lung lobectomy is considered the standard curative operation for early-stage non‑small cell lung carcinoma (NSCLC) when the tumor is confined to a single lobe and the patient has adequate pulmonary reserve. The procedure can be performed via open thoracotomy, video‑assisted thoracoscopic surgery (VATS), or robotic‑assisted thoracic surgery, each offering different profiles of invasiveness, postoperative pain, and recovery time. Indications include:
- Primary malignant neoplasms limited to a lobe
- Metastatic lesions confined to a lobe
- Severe localized infections such as bronchiectasis or tuberculous cavities
- Traumatic or congenital destruction of lobe tissue
Pre‑operative assessment typically includes pulmonary function tests, imaging (CT, PET), and cardiovascular evaluation to determine operative risk and postoperative lung capacity.
Etymology/Origin
The term combines “lung,” referring to the respiratory organ, with “lobectomy,” derived from the Greek lobos meaning “lobe” and the suffix -ectomy from the Greek ektome meaning “excision” or “removal.” Hence, “lobectomy” literally denotes the removal of a lobe.
Characteristics
| Aspect | Details |
|---|---|
| Anatomical target | One of the five lobes of the right lung (upper, middle, lower) or three lobes of the left lung (upper, lower, lingular segment sometimes considered a sub‑lobe). |
| Surgical approaches | • Open thoracotomy (large incision, rib spreading) • Video‑assisted thoracoscopic surgery (VATS) – small ports, thoracoscope • Robotic‑assisted thoracic surgery – enhanced dexterity and 3‑D visualization |
| Typical duration | 2–4 hours, depending on approach and patient factors. |
| Hospital stay | 3–7 days for VATS; up to 10 days for open thoracotomy. |
| Complications | Bleeding, air leak, pneumonia, bronchopleural fistula, postoperative atrial fibrillation, reduced pulmonary function. |
| Outcomes | Five‑year survival for stage I NSCLC after lobectomy ranges from 60–80 % with modern techniques. Functional loss is generally proportional to pre‑operative lung reserve; many patients retain satisfactory breathing capacity. |
| Post‑operative care | Pain control (often with epidural or intercostal nerve blocks), pulmonary physiotherapy, chest tube management, and gradual mobilization. |
