Parasitic Infections.

Parasitic infections of the gastrointestinal tract are a cause of morbidity to millions of individuals worldwide. These parasites are endemic in underdeveloped countries with poor sanitation allowing for spread through contaminated water supplies. While much is known about these parasites, the cutaneous manifestations caused by infection are infrequently reported in the literature.

Stapled hemorrhoidectomy with local anesthesia can be performed safely and cost-efficiently.

Purpose: This prospective study was designed to assess the feasibility of performing the procedure for prolapsing hemorrhoids, or stapled hemorrhoidectomy, under local anesthesia supplemented with conscious sedation.

Methods: Seventy consecutive patients (mean age, 56 years; 37 males) with Grade 3 or 4 hemorrhoids underwent the procedure for prolapsing hemorrhoids after perianal infiltration of 0.5 percent lidocaine with 1:200,000 epinephrine and supplemental conscious sedation.

Internal sphincterotomy with hemorrhoidectomy does not relieve pain: a prospective, randomized study.

Purpose: Pain after hemorrhoidectomy is universal. Several attempts have been made to reduce or alleviate the pain after excisional hemorrhoidectomy. The origin of pain is undetermined.
