    Abstract:
    In the last two decades, significant progress has been made in the diagnosis, prognostication and treatment of patients with severe peptic ulcer haemorrhage. Patients can now be risk stratified by clinical presentation and endoscopic stigmata of ulcer haemorrhage. The purposes of this chapter are to discuss: (1) the techniques of thermal probe with or without epinephrine for haemostasis of ulcers with major stigmata of haemorrhage and (2) the outcomes of treatment of patients with ulcer haemorrhage treated with endoscopic thermal probes or other therapies, medical therapy and/or surgery. Compared to medical therapy alone, patients with major stigmata actively bleeding ulcers, non-bleeding visible vessels and non-bleeding adherent clots have been shown to benefit from endoscopic haemostasis with bipolar probe, heater probe, lasers or epinephrine injection. Outcomes showing significant improvement include blood transfusions, emergency surgery rates and length of hospital stay. Meta-analyses have also reported improvements in mortality for endoscopic compared with medical therapy of patients with severe ulcer haemorrhage and major stigmata. Patients with minor stigmata of ulcer haemorrhage (such as flat spots) or no stigmata (clean-based ulcers) do not benefit from endoscopic haemostasis. Thermal probes have the advantages of good coaptive coagulation, target irrigation, portability and relative inexpense. Recently, patients with active arterial bleeding, non-bleeding adherent clots or non-bleeding visible vessels have been reported to have better results with combination epinephrine injection and thermal probe compared to monotherapy alone (such as injection, bipolar or heater probe). In addition, repeat endoscopic combination therapy has been reported to be as effective but safer than emergency surgery for management of recurrent ulcer haemorrhage.
