“…According to a recent study by van Turenhout et al, the rate of positive FOBT and negative colonoscopy was 221/434 (51%) [22], which was lower than that of our study. Our study showed that the rate of positive FOBT and negative colonoscopy was 243/340 (71.5%).…”

“…While 22.7% of internal hemorrhoid cases test positive for fecal occult blood, Goligher's classification shows no positive correlation 44) . Due to the number of false positives, the correlation of hemorrhoids to occult blood is not that high (~6.7%) 45) . In cases where complaints of prolapsing symptoms are inconsistent with the findings, straining testing in the toilet is useful 39,40) .…”

The pathogenesis of hemorrhoids is a weakening of the anal cushion and spasm of the internal sphincter. Bowel habits and lifestyles can be risk factors for hemorrhoids. The prevalence of hemorrhoids can encompass 4 to 55% of the population. Symptoms include bleeding, pain, prolapsing, swelling, itching, and mucus soiling. The diagnosis of hemorrhoids requires taking a thorough history and conducting an anorectal examination. Goligher's classification, which indicates the degree of prolapsing with internal hemorrhoids, is useful for choosing treatment. Drug therapy for hemorrhoids is typically utilized for bleeding, pain, and swelling. Ligation and excision (LE) is considered for Grade III and IV internal and external hemorrhoids. Rubber band ligation is used to treat up to Grade III internal hemorrhoids. Phenol almond oil is effective for internal hemorrhoids up to Grade III, while aluminum potassium sulfate and tannic acid have shown efficacy in treating prolapsing in internal hemorrhoids at Grades II, III, and IV. Procedure for prolapse and hemorrhoids (PPH) is surgically effective for Grade III internal hemorrhoids; however, the long-term prognosis is not favorable, with high recurrence rates. Separating ligation is effective surgical treatment for internal/external hemorrhoids Grade III and Grade IV. The basic approach to thrombosed external hemorrhoids and incarcerated hemorrhoids is conservative treatment; however, in some acute or severe cases, surgical resection is considered. Comparing the different instruments used for hemorrhoid surgery, all reduce operating time, blood loss, post-operative pain, and length of time until the return to normal activity. They do, of course, increase the cost of the procedure.
