Keighley | 1979 | Anal dilation vs sphincterotomy vs high fibre diet in high anal pressure RBL vs cryosurgery vs high fibre diet in lower anal pressure | Anal 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) | 1980 | RBL vs haemorrhoidectomy | Haemorrhoidectomy 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. |
Cheng | 1981 | Injection sclerotherapy vs RBL vs anal dilation vs haemorrhoidectomy | IST 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) | 1981 | Anal stretch with continued dilation vs anal stretch without continuous dilation | Continuous dilation improves the results of anal stretch |
Murie (63) | 1982 | RBL vs haemorrhoidectomy | Anal pain, pruritus, soiling were improved by both techniques. Haemorrhoidectomy is more successful in treating 3° haemorrhoids. |
O’Callaghan (64) | 1982 | Cryosurgery vs MM | Cryosurgery gave results similar to MM in patients with prolapsing piles with fewer complications and less time in hospital. |
Mortensen | 1987 | MM vs MM + anal dilation | Combination of MM with anal dilation may increase the risk of anal incontinence. |
Roe | 1987 | Submucosal haemorrhoidectomy vs Ligation/excision haemorrhoidectomy | No differences in pain and function found |
Asfar | 1988 | Anal stretch + haemorrhoidectomy vs sphincterotomy + haemorrhoidectomy | Routine sphincterotomy reduces pain, faecal soiling, urinary retention |
Rasmussen (65) | 1991 | Emergency haemorrhoidectomy vs incision and banding | Less pain after incision and banding, earlier discharge after incision and banding |
Hiltunen | 1992 | Anal dilation vs lateral subcutaneous sphincterotomy vs haemorrhoidectomy | Both anal dilation and sphincterotomy gave poor results in 25 % of patients |
Seow-Choen | 1992 | Conventional scissors excision/ligation vs diathermy excision without ligation | No differences in pain, but less analgesics after diathermy; diathermy is faster and causes less bleeding. |
Senagore (66) | 1993 | Cold scalpel vs Nd: YAG laser | More expenses and inflammation after laser treatment |
Yang (67) | 1993 | Bipolar coagulation vs direct current coagulation | Direct current causes more procedural pain. Postreatment rectal ulcerations occur more often after bipolar coagulation |
Randall (68) | 1994 | Bipolar vs direct current coagulation | Rebleeding is less frequent after direct current treatment, which produced fewer complications. |
Chia (69) | 1995 | CO2 laser vs conventional haemorrhoidectomy | Laser is associated with reduced postoperative analgesic requirement. |
Seow-Choen (70) | 1995 | Modified radical haemorrhoidectomy vs four piles haemorrhoidectomy | Results were less good after modified radical haemorrhoidectomy |
Mathai | 1996 | Haemorrhoidectomy vs haemorrhoidectomy + lat. Int. sphincterotomy | 2/17 patients had incontinence problems after lateral sphincterotomy |
Bassi | 1997 | Closed haemorrhoidectomy (Ferguson) vs Milligan Morgan vs diathermy haemorrhoidectomy | Faster canalization and minor pain after MM and diathermy. No difference in postoperative hemorrhage between MM and diathermy |
Ho | 1997 | Open haemorrhoidectomy vs closed haemorrhoidectomy | No difference in pain, analgesic requirements, length of hospital stays. Complete wound healing took significantly longer after closed haemorrhoidectomy |
Ibrahim | 1998 | Scissors closed haemorrhoidectomy vs diathermy closed haemorrhoidectomy | No difference in pain Diathermy seems to require les postoperative analgesic medication except in the first 24 h. |
Carapeti | 1999 | Open haemorrhoidectomy vs closed day case haemorrhoidectomy | No difference in pain, analgesia, complications. |
Cheetham | 2000 | Stapled haemorrhoidectomy vs standard haemorrhoidectomy | Persistent pain after stapled haemorrhoidectomy lead to suspension of the trial |
Galizia | 2000 | Lateral sphincterotomy + haemorrhoidectomy vs haemorrhoidectomy alone | Patients with lateral internal sphincterotomy had a better postoperative outcome |
Konsten | 2000 | Anal dilation (Lord's) vs haemorrhoidectomy | Anal dilation is associated with a high percentage of fecal incontinence |
Mehigan | 2000 | Stapled haemorrhoidectomy vs MM | Shorter anaesthesia time, less pain, and faster return to normal activity after stapled haemorrhoidectomy |
Rowsell | 2000 | Stapled haemorrhoidectomy vs conventional haemorrhoidectomy | Less pain, less hospital stay, faster return to normal activities after stapled haemorrhoidectomy |
