Table IIRandomized studies comparing open and closed haemorrhoidectomy, diathermy, anal dilation, and sphincterotomy

AuthorYearTechniqueResults
Keighley1979Anal dilation vs sphincterotomy vs high fibre diet in high anal pressure RBL vs cryosurgery vs high fibre diet in lower anal pressureAnal dilation was the only treatment that resulted in a significant reduction of anal pressure. More patients were improved by RBL. Patients with excessive activity of the internal sphincter are best treated by anal dilation.
Murie (61)1980RBL vs haemorrhoidectomyHaemorrhoidectomy relieved more patients after 1 year than RBL. However, haemorrhoidectomy caused pain in all patients, whereas RBL did not. Mean time off work was shorter after RBL.
Cheng1981Injection sclerotherapy vs RBL vs anal dilation vs haemorrhoidectomyIST was the least effective treatment Haemorrhoidectomy caused pain in all patients, RBL was painless in most patients RBL is the most appropriate method for 2° haemorrhoids
Greca (62)1981Anal stretch with continued dilation vs anal stretch without continuous dilationContinuous dilation improves the results of anal stretch
Murie (63)1982RBL vs haemorrhoidectomyAnal pain, pruritus, soiling were improved by both techniques. Haemorrhoidectomy is more successful in treating 3° haemorrhoids.
O’Callaghan (64)1982Cryosurgery vs MMCryosurgery gave results similar to MM in patients with prolapsing piles with fewer complications and less time in hospital.
Mortensen1987MM vs MM + anal dilationCombination of MM with anal dilation may increase the risk of anal incontinence.
Roe1987Submucosal haemorrhoidectomy vs Ligation/excision haemorrhoidectomyNo differences in pain and function found
Asfar1988Anal stretch + haemorrhoidectomy vs sphincterotomy + haemorrhoidectomyRoutine sphincterotomy reduces pain, faecal soiling, urinary retention
Rasmussen (65)1991Emergency haemorrhoidectomy vs incision and bandingLess pain after incision and banding, earlier discharge after incision and banding
Hiltunen1992Anal dilation vs lateral subcutaneous sphincterotomy vs haemorrhoidectomyBoth anal dilation and sphincterotomy gave poor results in 25 % of patients
Seow-Choen1992Conventional scissors excision/ligation vs diathermy excision without ligationNo differences in pain, but less analgesics after diathermy; diathermy is faster and causes less bleeding.
Senagore (66)1993Cold scalpel vs Nd: YAG laserMore expenses and inflammation after laser treatment
Yang (67)1993Bipolar coagulation vs direct current coagulationDirect current causes more procedural pain. Postreatment rectal ulcerations occur more often after bipolar coagulation
Randall (68)1994Bipolar vs direct current coagulationRebleeding is less frequent after direct current treatment, which produced fewer complications.
Chia (69)1995CO2 laser vs conventional haemorrhoidectomyLaser is associated with reduced postoperative analgesic requirement.
Seow-Choen (70)1995Modified radical haemorrhoidectomy vs four piles haemorrhoidectomyResults were less good after modified radical haemorrhoidectomy
Mathai1996Haemorrhoidectomy vs haemorrhoidectomy + lat. Int. sphincterotomy2/17 patients had incontinence problems after lateral sphincterotomy
Bassi1997Closed haemorrhoidectomy (Ferguson) vs Milligan Morgan vs diathermy haemorrhoidectomyFaster canalization and minor pain after MM and diathermy. No difference in postoperative hemorrhage between MM and diathermy
Ho1997Open haemorrhoidectomy vs closed haemorrhoidectomyNo difference in pain, analgesic requirements, length of hospital stays. Complete wound healing took significantly longer after closed haemorrhoidectomy
Ibrahim1998Scissors closed haemorrhoidectomy vs diathermy closed haemorrhoidectomyNo difference in pain Diathermy seems to require les postoperative analgesic medication except in the first 24 h.
Carapeti1999Open haemorrhoidectomy vs closed day case haemorrhoidectomyNo difference in pain, analgesia, complications.
Cheetham2000Stapled haemorrhoidectomy vs standard haemorrhoidectomyPersistent pain after stapled haemorrhoidectomy lead to suspension of the trial
Galizia2000Lateral sphincterotomy + haemorrhoidectomy vs haemorrhoidectomy alonePatients with lateral internal sphincterotomy had a better postoperative outcome
Konsten2000Anal dilation (Lord's) vs haemorrhoidectomyAnal dilation is associated with a high percentage of fecal incontinence
Mehigan2000Stapled haemorrhoidectomy vs MMShorter anaesthesia time, less pain, and faster return to normal activity after stapled haemorrhoidectomy
Rowsell2000Stapled haemorrhoidectomy vs conventional haemorrhoidectomyLess pain, less hospital stay, faster return to normal activities after stapled haemorrhoidectomy
