Surgical endoscopic techniques in the diagnosis and follow-up of patients with lymphoma.
BACKGROUND
In patients with lymphoma, tissue for histology can be obtained through image-guided techniques or by surgery. The aim of this study was to assess the efficacy of surgical endoscopic techniques in obtaining adequate tissue specimens.


METHODS
Ninety-two patients with suspected or confirmed lymphoma were referred for a surgical biopsy of a deeply located intrathoracic or intra-abdominal mass or lymph node. The 86 patients who had surgery using a surgical endoscopic technique were included in this study. There were 54 men and 32 women, of mean age 34 (range 15-78) years. Most were selected directly for surgery while five previously had a failed computed tomography-guided biopsy. A total of 89 procedures were performed in 86 patients: laparoscopy (15 patients), thoracoscopy (61) and mediastinoscopy (13).


RESULTS
No patient died. One intraoperative complication occurred during thoracoscopy (1 per cent). Two postoperative complications were noted (2 per cent). Three patients required conversion to open surgery (3 per cent). Adequate tissue for histology was obtained by surgical endoscopic procedures in 87 per cent. Twelve of 13 mediastinoscopies were successful. After thoracoscopy, the success rate was 92 per cent but only nine of 15 laparoscopies were considered successful.


CONCLUSIONS
In patients with lymphoma, surgical endoscopic techniques have a high diagnostic yield and a low morbidity rate. Barring exceptional circumstances these should be favoured rather than conventional open surgery.
