Recurrence Rates of Hemorrhoids After Treatment

Recurrence rates vary significantly by treatment modality and hemorrhoid type: surgical excision of thrombosed external hemorrhoids has the lowest recurrence at 6.3%, conventional excisional hemorrhoidectomy for internal hemorrhoids recurs in only 2-10% of cases, while rubber band ligation recurs in approximately 20-30% of patients, and conservative management of thrombosed external hemorrhoids has the highest recurrence at 25.4%. 1, 2, 3

Internal Hemorrhoids: Recurrence by Treatment Modality

Conservative Management

  • Conservative treatment alone (dietary fiber, water intake, phlebotonics) results in symptom recurrence reaching 80% within 3-6 months after cessation of phlebotonics 4, 5
  • This high recurrence rate makes conservative management appropriate only as initial therapy, not definitive treatment 4

Rubber Band Ligation (Grades I-III)

  • Overall success rate of 70.5-89% depending on hemorrhoid grade and follow-up duration 1, 4
  • Recurrence requiring retreatment occurs in approximately 20% of patients after initial rubber band ligation 5, 3
  • Long-term cumulative success rate reaches 80.2% when repeat banding is performed for recurrences 3
  • Time to recurrence decreases with subsequent treatment courses—first recurrence takes longer than second or third recurrences 3
  • Patients requiring 4 or more bands have higher failure rates and greater need for subsequent hemorrhoidectomy 3

Sclerotherapy (Grades I-II)

  • Short-term efficacy in 70-85% of patients, but long-term remission occurs in only one-third of patients 5
  • Higher recurrence rate compared to rubber band ligation, requiring more repeat treatments 1, 4
  • Retreatment rate of 23.3% in comparative studies 6

Surgical Hemorrhoidectomy (Grades III-IV)

  • Conventional excisional hemorrhoidectomy (Milligan-Morgan or Ferguson technique) has the lowest recurrence rate at 2-10% 1, 4, 5, 7
  • This represents the most definitive treatment with longest durability 1
  • Stapled hemorrhoidopexy has faster recovery but higher recurrence rates compared to conventional excisional techniques 1, 7

External Hemorrhoids: Recurrence by Treatment Modality

Conservative Management of Thrombosed External Hemorrhoids

  • Overall recurrence rate of 25.4% when treated conservatively 2
  • Mean time to recurrence is only 7.1 months 2
  • Most patients (80.6%) who experience recurrence were initially managed conservatively 2

Surgical Excision of Thrombosed External Hemorrhoids

  • Recurrence rate of only 6.3% after surgical excision 2
  • Mean time to recurrence is significantly longer at 25 months compared to 7.1 months with conservative management 2
  • Survival analysis demonstrates significantly longer time to recurrence with surgical treatment 2
  • Excision within 72 hours of symptom onset provides the best outcomes with lowest recurrence risk 4, 5, 2

Key Factors Affecting Recurrence

Treatment Timing

  • Thrombosed external hemorrhoids excised within 72 hours have lower recurrence rates than those treated conservatively or after 72 hours 4, 2
  • Patients presenting beyond 72 hours should receive conservative management as natural resolution has begun 4

Hemorrhoid Grade

  • Success rates for rubber band ligation are similar across all grades (I-III), but higher-grade hemorrhoids may require more bands 3
  • Grade IV hemorrhoids require surgical hemorrhoidectomy for lowest recurrence rates 1, 4

Number of Treatment Sessions

  • Patients requiring 4 or more rubber bands have higher failure rates 3
  • Time to recurrence decreases with each subsequent treatment course 3

Clinical Pitfalls to Avoid

  • Never assume simple incision and drainage is adequate for thrombosed external hemorrhoids—this leads to persistent bleeding and significantly higher recurrence rates 4, 2
  • Do not attribute recurrent bleeding to hemorrhoids without proper colonic evaluation, as other pathology may be present 4
  • Avoid using conservative management alone for grade III-IV hemorrhoids, as recurrence approaches 80% within months 4, 5
  • Do not perform anal dilatation as it causes 52% incontinence rate at long-term follow-up without reducing recurrence 1, 4
