THD and mucopexy: Efficacy and controversy
Annals of Medicine & Surgery, 2017 Transanal haemorrhoidal dearterialisation and mucopexy has evolved in recent years as a popular minimally invasive non-excisional surgery for symptomatic prolapsing haemorrhoids. The long-term outcome of this procedure however, remains to be established.

Transanal Hemorrhoidal Dearterialization With Doppler Arterial Identification Versus Classic Hemorrhoidectomy: A Retrospective Analysis of 270 Patients [PDF]
Annals of Coloproctology, 2019 Purpose Despite the minimally invasive nature of transanal hemorrhoidal dearterialization (THD) with Doppler arterial identification procedures, hemorrhoidectomy is still considered the gold standard procedure for hemorrhoidal disease.

Clustering phenomena of implants in tungsten observed with THDS [PDF]
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1985 A W(100) single crystal was irradiated with 5-10 keV of different metallic species (Ag, Cu, Cr, Mn, Al and In). Subsequently the crystal was annealed at temperatures ranging from room temperature to 2400 K. Thermal helium desorption spectrometry (THDS) was applied to monitor the dissociation and clustering reactions of defect complexes either formed at

Special conditions in the treatment of hemorrhoidal disease. The advantages of THD-RAR in the treatment of hemorrhoidal disease in these situations [PDF]
Romanian Medical Journal, 2020 Introduction. The prevalence of hemorrhoids in the general population ranks first among benign anorectal diseases. In the last 20 years, however, the number of cases operated for hemorrhoidal disease has decreased and consequently the experience of ...
