A. Carazzone et al., Endoscopic palliation of oesophageal cancer: Results of a prospective comparison of Nd : YAG laser and ethanol injection, EURO J SURG, 165(4), 1999, pp. 351-356
Objective: To evaluate the effectiveness of intratumoral alcohol injection
compared with Nd:YAG laser in the treatment of unresectable fungating cance
rs of the oesophagus.
Design: Prospective, randomised clinical study.
Setting: University hospital, Italy.
Subjects and interventions: 47 consecutive patients were randomly allocated
to have endoscopic Nd:YAG laser treatment (n = 24), or intratumoural injec
tion of 98% alcohol (n = 23).
Main outcome measures: Morbidity, mortality, dysphagia score, survival.
Results: One patient in the laser group needed analgesic support during and
after the treatment, whereas 18 (78%) of those treated with alcohol experi
enced mild pain and most of them required analgesics. An improvement of at
least 2 points in the dysphagia score was noted in 21 patients (88%) in the
laser group and in 18 in the alcohol group (78%). The mean dysphagia-free
intervals between each treatment were 30 and 37 days, respectively. The med
ian survival was 6 months in each group. There were no significant differen
ces in the mean dysphagia scores of patients still alive. There were no com
plications in the laser group, but one oesophageal perforation occurred dur
ing the preliminary dilatation before the second session of alcohol injecti
on. There were no procedure-related deaths.
Conclusion: The two techniques allowed similar palliation of dysphagia and
improvement of quality of life. Intratumoral injection of alcohol is an eff
ective and inexpensive therapeutic option in the palliation of fungating oe
sophageal lesions.
