“…There have been 5 controlled trials published (3 Ng-YAG and 2 argon) since Keifhaber published his results in 1978 (Keifhaber et al, 1978). Three have shown the same results as oursno significant reduction in mortality or rebleeding following treatment (Ihre et al, 1981;Rutgeerts et al, 1982;Vallon et al, 1981).…”

Summary:104 consecutive patients with upper gastrointestinal bleeding admitted to a district general hospital over a period of 20 months were considered for laser photocoagulation. 58 patients were found to have peptic ulcers, of which 42 had stigmata of recent haemorrhage accessible to laser photocoagulation. 17 were treated with a Nd-YAG laser and 25 were managed conservatively. There was no significant difference in the number of patients who re-bled and required surgery, mortality rate, length of stay in hospital or the amount of blood transfusion required in either group. We suggest that the routine use of a laser for bleeding peptic ulcers in a district general hospital is not justified.

Kiefhaber P. Indications for endoscopic neodymium-YAG laser treatment in the gastrointestinal tract. Twelve years' experience. Scand J Gastroenterol 1987,22(suppl Application of clinical endoscopic Nd: YAG laser (A = 1.06 pm) therapy has been introduced in 1975. It is suitable to stop all kinds of gastrointestinal bleeding with a primary success rate of 94% (1 144/1212). Compared to surgical results a reduction in mortality rate has been achieved. These results have been confirmed worldwide in routine clinical application and in controlled trials with selected patients. Potential bleeding lesions such as Osler haeinangiomas and angiodyspl Recanalization of inoperable obstructed oesophageal and gastric carcinoma by laser vaporization to relieve dysphagia and subsequently endoscopic iridium after loading irradiation show a medium survival time of 7.4 months. Preoperative recanalization of obstructed colorectal carcinoma to relieve ileus or subileus allows preoperative peroral bowel lavage and total colonoscopy to find synchronous cancers and polyps and to perform primary resections without intraoperative colon lavage. Sessile benign neoplastic polyps can be resected curatively by Nd: YAG laser vaporization. Recanalization of peptic stenosis and anastomotic scar stenosis can be performed.

“…The series includes treatment of 40 patients with bleeding esophageal varices. Kiefhaber and Nath reported a reduction in mortality rate in highrisk patients with bleeding ulcers by comparison with earlier years [33]. This is, at best, an uncertain method of comparison, particularly in a center with a changing referral base.…”

Laser photocoagulation in alimentary bleeding

Laser therapy is theoretically more advantageous than endoscopic techniques such as diathermy in the treatment of alimentary bleeding primarily because the bleeding point is not directly touched or handled during therapy and the amount of energy dissipated in the surrounding tissue is more easily controlled. Only Argon and Neodymium‐Yttrium Aluminum Garnet (Nd Yag) laser beams can be passed down flexible wave guides suitable for endoscopic use in clinical gastroenterology. The Argon laser has been used by several groups for the treatment of patients with upper gastrointestinal bleeding. Success has been achieved in 80 to 95 percent of patients. Randomized trials comparing laser therapy to other modalities or to conservative, nonendoscopic therapy have in general suggested a greater benefit and lower incidence of rebleeding following laser application. Prospects for the utilization of lasers in patients with gastrointestinal bleeding depend crucially on the correct execution of randomized controlled trials currently in progress.
