Intraoperative neoplastic cell contamination Involvement of the lymph nodes in resection limits Positive resection margins Perforated cancer Peritoneal Implants confirmed with biopsy Ovarian involvement Invasion of nearby organs or structures. YAG laser with a wavelength of 1, nm delivers near infrared radiation via a flexible quartz fiber.
Accordingly, patients are at significant risk for retinal injury and severe sunburn manifested by erythema and blisters. One complication is airway fire. Workup of cirugiz should include basic laboratory indices. This decreased reactivity makes silicon stents easy to extract if necessary.
Stents may also prove invaluable in the management of esophageal cancer complicated by the development of tracheoesophageal fistula.

Although we use this modality more often for endoluminal control of unresectable esophageal cancer, it can certainly be applied to advanced lung cancer with airway involvement. Effective treatment requires experience with flexible and rigid bronchoscopy.
Flexible bronchoscopy can be useful for the application of YAG laser therapy, photodynamic therapy, and to localize bleeding site within the airway. A major advantage of silicon stents is that they are less irritating and subsequently ciruga in less granulation tissue formation.
The authors also reported the use of the laser for tracheal stenosis and granulomas. J Bronchol ; 3: Furthermore, careful analysis of radiographs is essential when approaching these patients.
Fiber optic bronchoscopy is the mainstay in the detection of recurrent endobronchial tumor; however white light bronchoscopy is limited in its ability to localize occult tracheobronchial recurrences. This activity produces singlet oxygen, which subsequently generates superoxide and hydroxyl radicals.
Symptoms may include unexplained progressive dyspnea, frequent dry cough, bronchospasm, or hemoptysis. Light energy may also be used for diagnosis in this setting. You can help Wikipedia by expanding it. The authors prefer general anesthesia for most cases of endobronchial therapy because of the greater degree of airway control and the rapidity of operation that is allowed.
Often stent placement is preceded by tumor debulking using the Nd: Autofluorescence bronchoscopy in the detection of squamous metaplasia and dysplasia in current and former smokers.
YAG laser is not without risks. Special attention to detail and judicious use of the laser will avoid untoward events in most cases. As mentioned, the laser may be used with either the flexible or rigid scope. With the exception of carcinoid tumors and rare localized endobronchial squamous cell cancer in good risk patients, endobronchial palliation is the mainstay in the treatment of patients with unresectable endobronchial malignancies.
This may be suggested by aerated lung or patent bronchial passages on CT scan. Physical examination should include but not be limited to an evaluation of the patients overall condition including respiratory status, breath sounds and end organ perfusion. The flexible endoscope can be inserted through the rigid scope to allow for precise coagulation of more distally located tumors. The appropriately sized stent, based upon length and luminal diameter, is then advanced over the wire and positioned under fluoroscopic guidance.
Additional precautions relate to the accumulation of the photosensitizer in normal tissues. Contraindications to rigid bronchoscopy include bleeding diathesis, cervical spine injury or severe degenerative cervical disease with a poor range of motion.
YAG laser in bronchial endoscopy.
The peritoneal carcinomatosis tumors that can be dealt with thanks to a combined radical treatment are the following, depending on evidences seen nowadays: Sunscreens are ineffective in protecting against phototoxicity. The proximal end of the stent and a 36 Fr chest cirguia are loaded onto the rigid scope fn described above. Epithelial ovarian carcinoma Colorectal cancer Gastric cancer Diffuse peritoneal mesothelioma Pseudomyxoma peritonei Peritoneal sarcomatosis It is necessary to apply intraperitoneal chemotherapy in the following cases, bulkibg expected mechanisms of tumoral cell implantation in the peritoneum: Lesions located distally along the airway are generally not amenable to rigid bronchscopy.
Under direct vision, the rigid ccirugia places the stent within the affected area. Traditionally considered as incurable, recent studies have shown that som patients can clearly benefit form radical surgical approach combined with different kinds of chemotherapy. There is a wide variety of this type of carcinomatosis depending on the peritoneal involvement, from small and superficial nodes near the primary tumor to a complete occupation of the abdominal cavity by big invasive tumor deposits.

Endobronchial stents are particularly useful in the management of unresectable lung cancer with direct endobronchial ingrowth or extrinsic compression. For patients who have undergone therapy for endobronchial tumor, surveillance is necessary to identify recurrent disease early.
The flexible scope can be inserted through the rigid bronchoscope to reach the distal left main stem and upper lobe orifices.
This mechanism has resulted in cardiovascular collapse manifested by arrhythmias, hypotension and even cardiac arrest in some cases. Rev Fr Mal Respir ; 7: Our preference is to perform the vascular division and fissure separation prior to bronchotomy.
Endoluminal management of malignant airways disease. The chest tube effectively keeps the silicon stent in position while it is disengaged from the rigid scope Figure 7.
This page cirrugia last edited on 12 Octoberat This manoeuver is key to correcting the size discrepancy between the proximal and distal bronchi. Our practice is to liberally lubricate the shaft of the rigid bronchoscope. J Invest Dermatol ;
