Stapling procedure for haemorrhoids versus Milligan-Morgan haemorrhoidectomy: randomised controlled trial

How to make a silk purse from a sow's ear--a comprehensive review of strategies to optimise data for corrupt managers and incompetent clinicians

The introduction of performance league tables for UK surgeons and hospitals has forced them to learn how to present data in the best possible light. Though there is an urgent need for guidance, official guidelines on how to optimise performance data are lacking

Stapled hemorrhoidectomy for the treatment of hemorrhoids

BACKGROUND

The use of circular staplers in the treatment of hemorrhoidal disease is known as a simple procedure, with low morbidity, less post-treatment pain and with the same efficacy when compared to the classical hemorrhoidectomy.

AIM

Analyze the operative technique, intra-operative and immediate postoperative complications and late results in 100 patients treated for hemorrhoid disease by stapling technique.

PATIENTS AND METHODS

The group included 53 males and 47 females with mean age of 49.8 years, operated during the period June 2000 to June 2002 in the "Hospital Universitário" (São Paulo University Hospital) and "Hospital Sírio Libanês", in São Paulo, SP, Brazil.

RESULTS

The majority of patients (78%) were discharged on the first post-operative day. Eight patients required supplementary analgesia and were given intramuscular diclofenac sodium and four of them received intramuscular tramadol. One intraoperative complication was bleeding which was difficult to control and required a blood transfusion. One patient was reoperated on the first postoperative day due to intermittent and persistent bleeding, however without hemodynamic changes or a drop in hematocrit. Two patients presented hemorrhoidal thrombosis in the early postoperative stage. The postoperative follow-up displayed: recurrence of prolapse, five cases (5%); anal sub-stenosis, two cases (2%); anal fissure, one case (1%); persistent pain, two cases (2%). Seven reoperations were performed: one due to bleeding, one due to sub-stenosis and five due to recurrence of hemorrhoidal prolapse and persistence of symptoms.

CONCLUSIONS

Stapling is simple to accomplish, has low postoperative pain and rate of complications, however, the incidence of late reoperations is rather high and therefore major follow-up for better analysis is required.

Management options for symptomatic hemorrhoids

Hemorrhoids remain one of the most common colorectal complaints. They are defined as a pathologic engorgement of the submucosal vascular plexus. Although they are often asymptomatic, hemorrhoids may cause bleeding, prolapse and, less commonly, pain. This review gives an update on various treatment options for symptomatic hemorrhoids, which include conservative treatments, office interventions, and surgical procedures, depending on the individual constellation of symptoms. Objective findings and expectations are also addressed. Recent advances (eg, stapled hemorrhoidectomy and use of alternate energy sources) are emphasized, and treatment under special circumstances (HIV, pregnancy, inflammatory bowel disease, and liver disease) is outlined.

Stapled haemorrhoidectomy: a novel procedure

Stapled haemorrhoidectomy is an effective procedure for symptomatic haemorrhoids with mucosal prolapse. The advantages over the conventional surgical technique include reduced postoperative pain, shorter hospital stay and earlier return to work.

Stapled hemorrhoidectomy: initial experience of a Latin American group

The purpose of the present study was to determine the value of circular hemorrhoidectomy (procedure for prolapse and hemorrhoids [PPH]) on the basis of data collected prospectively during the initial experience of a group of Latin American surgeons. Between 2000 and 2001, PPH was performed using a circular stapler in 177 patients who had third- and fourth-degree hemorrhoidal disease. The average age of the patients was 47.7 years (range 26 to 85 years). Anal bleeding was the most common preoperative complaint (93.2%) followed by anal pain (60.2%), anal itching (43%), and constipation (41%). Hemorrhoids were classified as third degree in 132 patients (74%) and fourth degree in 45 patients (25.4%). Skin tags were detected in 86 patients (48.8%) and rectocele in 14 patients (7.9%). Data collected included patient demographics, type of anesthesia, and specific details of the surgery such as duration of the operation, distance from the staple line to the dentate line, need for complementary hemostasis, and any unexpected occurrences. Postoperative data collected included the degree of pain, which was evaluated on the basis of the type and dosage of analgesics required, laxative consumption, and the presence of bleeding, fever, urinary retention, or hematomas. Each patient completed a written questionnaire addressing these events. Patients returned for follow-up visits on days 7, 15, 30, and 90. Responses to pain, bleeding, fever, anal continence, recurrence of hemorrhoids, and level of satisfaction were compiled. The duration of the procedure ranged from 6 minutes to 2 hours (average 23 minutes), and most operations lasted no more than 20 minutes, with the exception of one that lasted 2 hours because of intraoperative bleeding. Intraoperative problems were minor. An additional one or a few sutures were required in 58.7% of patients to achieve perfect hemostasis. In 128 patients (72.3%) the hospital stay was less than 24 hours. Same-day surgery was chosen for 37 patients (20.9%). Pain was controlled with analgesia only using one to six doses of oral dipirona in 126 patients. Five patients were readmitted to the hospital: four for control of bleeding and one for conventional hemorrhoidectomy due to an acute episode of external hemorrhoidal thrombosis. At day 30, patients rated the efficacy of the procedure in alleviating preoperative symptoms as follows: 77.5% excellent; 16% good; 5.3% average, and 1.2% poor. At 3 months postoperatively no patient had had a recurrence of hemorrhoidal prolapse, and there were no instances of stenosis or anal incontinence. Surgeons also rated the efficacy of the procedure as excellent in 75%, good in 19.8%, average in 4.7%, and poor in 0.6%. With proper selection of patients and adequate stapling technique, stapled hemorrhoidectomy may be considered safe; it is easily learned, has a satisfactory degree of pain, and is well accepted by both patients and surgeons.

Stapled haemorrhoidectomy compared with Milligan-Morgan excision for the treatment of prolapsing haemorrhoids: a prospective study

OBJECTIVE

To compare stapled haemorrhoidectomy with Milligan-Morgan haemorrhoidectomy.

DESIGN

Prospective open study.

SETTING

Teaching hospital, Greece.

PATIENTS

85 patients with prolapsing haemorrhoids were invited to choose between stapled and Milligan-Morgan haemorrhoidectomy. 48 chose the former and 37 the latter.

INTERVENTIONS

Operation. Postoperatively, the patients were given analgesics on demand, and were discharged as soon as their condition and particularly their pain had improved.

MAIN OUTCOME MEASURES

Patients' symptoms and their opinion about the procedures, which were recorded during their follow-up which lasted for 6 months.

RESULTS

Stapling resulted in a significantly shorter operating time, and less postoperative pain and other symptoms, than Milligan-Morgan excision (p < 0.001). Postoperative complications, and mean time in hospital did not differ significantly between the two groups. During the follow-up period there was no significant difference in the incidence of recurrences between the two groups. Six months after the operation, significantly more patients in the stapled group had residual skin tags-external haemorrhoids than in the Milligan-Morgan group, and all these patients had fourth degree haemorrhoids.

CONCLUSIONS

Stapled haemorrhoidectomy is a promising method of treatment for prolapsing third degree haemorrhoids. Its effectiveness is questionable for fourth degree ones. Initially, the results are as good as after Milligan-Morgan haemorrhoidectomy, especially for third degree haemorrhoids. However, more patients and longer follow-up periods are required for its long-term efficacy to be confirmed.

Stapled haemorrhoidopexy: a consensus position paper by an international working party - indications, contra-indications and technique

An international working party with experience in the performance of an alternative haemorrhoid operation through the use of the circular stapler was convened for the purpose of developing a consensus as to the criteria for undertaking this procedure. The agenda consisted of first, naming the operation; second, the indications and contra-indications for its performance; and third, the preferred surgical technique. Among the recommendations for individuals who plan to embark on this surgery are that experience with anorectal surgery and an understanding of anorectal anatomy are requisites; experience with circular stapling devices is essential; and the surgeon must attend a formal course which should include lectures, videos, the application of the instrument in models, and observation of the operation as performed by a surgeon recognized by his or her peers-leading ultimately to undertaking the procedure while being observed by an experienced surgeon. Following satisfactory completion of the above, independent responsibility should be determined by an individual's department of surgery.

Stapled versus excision haemorrhoidectomy: long-term follow up of a randomised controlled trial

Advantages of the stapling procedure for haemorrhoids include reduced postoperative pain and shortened convalescence; however, there are few data with respect to functional and symptomatic outcome. At a dedicated clinic, we reviewed patients between Dec, 2001, and March, 2002, who had taken part in a randomised controlled trial undertaken at the unit in 1999, which compared outcomes after open or stapled haemorrhoidectomy. We noted the presence or absence of haemorrhoid specific symptoms, and assessed overall satisfaction, continence, and quality of life. Rigid sigmoidoscopy and an anorectal examination were also used to examine symptomatic recurrence and disease activity. At minimum follow-up of 33 months since surgery, both techniques seem to be equally effective.

Prospective randomized study of bacteraemia in diathermy and stapled haemorrhoidectomy

BACKGROUND

The incidence and consequences of bacteraemia associated with diathermy and stapled haemorrhoidectomy have not been studied previously.

METHODS

Two hundred and five healthy patients randomized to stapled haemorrhoidectomy or diathermy haemorrhoidectomy had perioperative blood cultures taken. The clinical sequelae of bacteraemia and complications of surgery were assessed prospectively.

RESULTS

Six patients were excluded for protocol violations. Eleven (11 per cent) of 101 patients with stapled and five (5 per cent) of 98 who had diathermy haemorrhoidectomy had positive blood cultures for organisms after haemorrhoidectomy, predominantly anaerobes commonly found within the bacterial flora of the anorectum (P = 0.19). Transient postoperative pyrexia in several patients did not correlate with detected bacteraemia and settled spontaneously without treatment. There were no serious complications from either operative technique, and no clinical consequences from proven bacteraemia.

CONCLUSION

Transient bacteraemia may complicate surgical haemorrhoidectomy but has no serious clinical consequences for healthy adults.

Septic complications after treatment of haemorrhoids

BACKGROUND

Recent reports of serious sepsis following stapled haemorrhoidectomy have raised concerns about the appropriate treatment of haemorrhoidal disease.

METHODS

A Medline search was undertaken for reports of sepsis following the commonly practised conservative and surgical treatments of haemorrhoids.

RESULTS

Published accounts of significant septic complications after injection sclerotherapy, rubber-band ligation, cryotherapy, open and closed haemorrhoidectomy, and stapled haemorrhoidectomy are discussed. This is supplemented by the authors' own experiences of stapled haemorrhoidectomy.

CONCLUSION

Septic complications following both conservative and surgical treatment of haemorrhoids are rare but may be catastrophic. Immunological compromise poses an additional risk for many treatment modalities. The technique of stapled haemorrhoidectomy should be learned diligently to avoid septic complications.

Stapled anoplasty for haemorrhoids: a comparison of ambulatory vs. in-patient procedures

OBJECTIVE

Haemorrhoids are commonly seen in colorectal practice. Stapled anoplasty is a novel approach to the treatment of this condition and is usually performed as an in-patient procedure. The aim of this study was to investigate the suitability of this technique for ambulatory surgery.

PATIENTS AND METHODS

Fifty consecutive patients undergoing stapled anoplasty under general anaesthesia as day cases (DC) (mean age 41 years; 27 females) by a single consultant surgeon over a 12-month period were compared with 50 consecutive patients undergoing the same procedure as in-patients (mean age 44 years; 25 females) (IP) during the same period.

RESULTS

Eight DC patients (16%) were admitted overnight from the day surgery unit for urinary retention (3), pain (2), bleeding (2) and anaesthetic reasons (1). Three other DC patients were re-admitted after a mean period of 4 days with bleeding (2), one of which required surgical haemostasis, and a septic complication (1). Mean hospital stay for IP cases was 2.6 (range 1-9) days. Two IP cases were re-admitted after 4 and 11 days for bleeding and wound infection, respectively. At review 2-4 weeks after discharge, satisfaction in both groups was high. Minor staple-line strictures were seen in 1 DC and 2 IP cases but all were easily dilated digitally. Mean costs incurred were significantly less for day surgery patients.

CONCLUSIONS

Stapled anoplasty is suitable for use in day-case surgery as it is a quick and relatively painless procedure. The advantages, particularly financial, support the technique for use in an ambulatory setting, preferably in the morning, and provided detailed patient advice is given.

Hemorrhoids

Technologic advances have contributed to numerous diverse approaches to the management of hemorrhoid disease over the past centuries. Better understanding of the pathophysiology and anatomy of the anal canal has also added to the increased success in the treatment of hemorrhoids. This article reviews the clinical and pathological aspects of hemorrhoid disease, emphasizing new therapeutic modalities.

Histopathology of stapled haemorrhoidectomy specimens: a cautionary note

OBJECTIVE

Stapled haemorrhoidectomy is a new technique with encouraging early results. The aim of this study was to examine the tissue removed during stapled haemorrhoidectomy, in particular to check on the presence or absence of transitional or squamous anal canal mucosa and internal anal sphincter muscle.

METHODS

Twenty-six consecutive patients undergoing stapled haemorrhoidectomy were studied. Resected tissue was examined histologically according to a standardized histological protocol.

RESULTS

All 26 specimens contained columnar mucosa. Twelve specimens also contained anal transitional and stratified squamous epithelium. Two specimens contained columnar and transitional mucosa. Twenty-two of 26 specimens contained smooth muscle as well as mucosa (median maximum diameter 7.5 mm, range 2-20 mm). In 11 specimens this was circular muscle only; in 11 circular and longitudinal smooth muscle were present. In 10 specimens smooth muscle was seen to be lying beneath stratified squamous or transitional epithelium, suggesting that it was from the internal anal sphincter.

CONCLUSIONS

Stapled haemorrhoidectomy results in resection of stratified squamous mucosa or part of the internal anal sphincter in a significant proportion of patients. Surgeons should be aware that this technique may result in damage to the internal anal sphincter.

Randomized clinical trial of stapled haemorrhoidopexy versus conventional diathermy haemorrhoidectomy

BACKGROUND

The aim of this study was to compare the results of stapled haemorrhoidopexy (commonly called stapled haemorrhoidectomy) with those of conventional diathermy haemorrhoidectomy.

METHODS

Fifty-five patients with symptomatic third- and fourth-degree haemorrhoids were randomized to either stapled haemorrhoidopexy (n = 27) or conventional diathermy haemorrhoid ectomy (n = 28). Operating time, postoperative pain, time to return to work, postoperative complications and effectiveness of haemorrhoidal symptom control were recorded. The mean follow-up was 15.9 months in the stapled haemorrhoidopexy group and 15.2 months in the conventional haemorrhoidectomy group.

RESULTS

Mean pain intensity was significantly less in the stapled group (P = 0.001). There were no significant differences in the total number of complications, the length of absence from work or control of symptoms. Seven patients in the stapled group re-presented with prolapse compared with none in the conventional haemorrhoidectomy group (P = 0.004). This difference was also observed in the subset of patients with fourth-degree haemorrhoids (P = 0.003).

CONCLUSION

The stapled operation was significantly less painful than conventional haemorrhoidectomy. However, the rate of recurrent prolapse was higher after stapled haemorrhoidopexy than after conventional diathermy haemorrhoidectomy.

The contemporary management of haemorrhoids

BACKGROUND

New concepts in the management of haemorrhoidal disease have recently rekindled interest in this common pathology. General and subspecialist colorectal surgeons were surveyed to assess their impact on the current management of haemorrhoids.

METHODS

A questionnaire was sent to all members of the Association of Coloproctology of Great Britain and Ireland (ACPGBI) and the Association of Surgeons of Great Britain and Ireland (ASGBI). Regarding indications for surgery, surgical techniques, day case haemorrhoidectomy (DCH) and postoperative treatment regimens. ASGBI members were asked to state their subspecialist interest and estimated time devoted to colorectal practice.

RESULTS

There were 406 (71%) ACPGBI respondents and 483 (68%) ASGBI respondents. Eighty-four (12%) ASGBI respondents performed no elective colorectal surgery. One hundred and ninety-nine (35%) of ACPGBI respondents saw between 6 and 10 new haemorrhoid patients per week whereas three hundred (42%) of ASGBI respondents saw between 1 and 5 per week. Non-operative management included routine advice on fluid and diet by the majority of surgeons, with banding carried out in 79% (ACPGBI) and 75% (ASGBI) and injection sclerotherapy in 61% (ACPGBI) and 56% (ASGBI). The Milligan Morgan haemorrhoidectomy was performed in 265 (46%; ACPGBI) and 336 (47%; ASGBI). ACPGBI members used Submucosal diathermy (148, 26%vs 67, 9%; ASGBI (P < 0.01; chi2 test with Yates correction)) and stapled anoplasty (61, 11%vs 14, 2%; ASGBI (P < 0.01; chi2 test with Yates correction)) more often. DCH was performed in 117 (20%; ACPGBI) and in 48 (7%; ASGBI)(P < 0.01; chi2 test with Yates correction).

CONCLUSIONS

In this sample of surgeons, operative management varies according to specialist interest. There was a trend towards day case haemorrhoidectomy. Whilst more surgeons have accepted the use of postoperative techniques to reduce pain, only a small minority have, as yet, adopted new surgical techniques such as stapling.

Objective comparison of stapled anopexy and open hemorrhoidectomy: a randomized, controlled trial

PURPOSE

This trial compares stapled anopexy with open hemorrhoidectomy in patients with prolapsing (Grade 3) hemorrhoids. Particular attention was paid to changes in anorectal physiology, nature of tissue resected, quality-of-life assessments, and cost implications of the treatments studied.

METHODS

An initial pilot study was followed by a randomized, controlled trial in a District General Hospital in the United Kingdom. All patients had Grade 3 hemorrhoids. Nineteen patients were studied in the pilot study, with 99 patients in the randomized, controlled trial. All patients in the pilot study and 59 in the randomized, controlled trial underwent stapled anopexy. Thirty patients in the randomized, controlled trial underwent open hemorrhoidectomy. Of the 59 patients in the stapled group, 32 were treated with the Ethicon PPH stapling device, and 27 received stapling with a reusable Autosuture stapling device. The following variables were measured: demographic details, quality of life (Medical Outcomes Study Short Form 36 and directed questions), anorectal manometry, and histology.

RESULTS

There was no difference in the case mix within or between the groups. The stapled anopexy groups showed a significant reduction in operative time (P < 0.001) and blood loss (P < 0.001) compared with open hemorrhoidectomy. Open hemorrhoidectomy resulted in significantly greater usage of protective pads postoperatively (P < 0.001) and longer rehabilitation (P < 0.006).

CONCLUSIONS

Stapled anopexy is an effective alternative treatment for prolapsing hemorrhoids that allows reduced operative time and shorter rehabilitation. It does not appear to affect continence or overall quality of life.

Stapled rectal mucosectomy vs. closed hemorrhoidectomy: a randomized, clinical trial

INTRODUCTION

We compared the safety and clinical outcome between stapled rectal mucosectomy and closed hemorrhoidectomy for the surgical treatment of noncomplicated hemorrhoidal disease.

METHODS

Eighty-four patients with Grade III and IV hemorrhoidal disease were randomly assigned to two groups: 1) stapled rectal mucosectomy group (n = 42) and 2) closed hemorrhoidectomy group (n = 42). Postoperative pain, analgesic use, symptoms, disability, early and late complications, and patient satisfaction were evaluated, among others. Follow-up was six months.

RESULTS

Eighty-four patients, averaging 45 +/- 9 years of age, underwent surgery. Two were lost to follow-up. Length of surgery and disability, postoperative pain, and use of analgesics were significantly less for patients in the stapled rectal mucosectomy group. In the closed hemorrhoidectomy group early complications were more frequent but not statistically significant, and there were no statistically significant differences regarding the frequency of late complications. No serious complications were reported in either group. Closed hemorrhoidectomy proved to be superior for bleeding control (95.1 percent closed hemorrhoidectomy 80.5 percent stapled rectal mucosectomy; P= 0.04). Patient satisfaction was similar in the two groups, but stapled rectal mucosectomy patients were more willing to undergo the same procedure (P = 0.02).

CONCLUSION

Both stapled rectal mucosectomy and closed hemorrhoidectomy are safe procedures. Closed hemorrhoidectomy was superior for bleeding control in Grade III and IV hemorrhoidal disease, but more painful and disabling than stapled rectal mucosectomy.

A randomized, double-blind trial of the effect of metronidazole on pain after closed hemorrhoidectomy

PURPOSE

Patients consider hemorrhoidectomy to be a painful operation. Attempts to reduce the length of inpatient stay have concentrated mainly on a reduction in postoperative pain. Metronidazole has been shown to reduce pain after open hemorrhoidectomy. The aim of this study was to evaluate the effect of metronidazole after closed hemorrhoidectomy.

METHODS

Thirty-eight patients undergoing closed hemorrhoidectomy were randomly allocated to receive metronidazole 400 mg (n = 18) or placebo (n = 20) three times daily for seven postoperative days. All patients received a stool softener and analgesics perioperatively. Linear analog scales were used to assess expected pain, actual pain and patient satisfaction. Time to first bowel movement, return to normal activity, complications, and use of additional analgesics were recorded.

RESULTS

Both groups of patients experienced less pain than expected. Patients in the metronidazole group required fewer additional analgesics postoperatively (6.3 vs. 26.3 percent), and satisfaction scores in the placebo group were higher at one week (0.5 vs. 2.5), although these differences were not statistically significant. There were no differences in pain actually experienced, time to first bowel movement, return to normal activity, or complications between the two groups. Satisfaction scores at six weeks for all patients were relatively high, with no significant difference between the groups.

CONCLUSION

Closed hemorrhoidectomy results in high patient satisfaction and low pain scores. The use of postoperative metronidazole did not reduce postoperative pain.

Acute rectal obstruction after PPH stapled haemorrhoidectomy

An unusual case of acute intestinal obstruction following a PPH stapled haemorrhoidectomy is reported: the complication was due to an almost complete interruption of the rectal lumen tightened by a purse-string suture anchored by staples. The stricture was dilated and the suture released thus restoring intestinal continuity. Surgeons should be aware that such troublesome complication may occur and can be treated successfully by a transanal approach.

Initial experience with stapled anoplasty in the operative management of prolapsing hemorrhoids and mucosal rectal prolapse

BACKGROUND

Excisional hemorrhoidectomy has remained the standard procedure in the operative management of hemorrhoids. Innovations in surgical technique have recently been introduced to try to decrease the pain associated with it. Stapled anoplasty has had promising early results in this regard. The aim of this study was to determine the ease or difficulty in introducing this new procedure, its efficacy, safety, and pain profile.

DATA SOURCES

Nineteen patients underwent stapled anoplasty and were followed up from 8 weeks to 6 months postoperatively. Data were accrued through clinical evaluation and patient questionnaires.

CONCLUSIONS

Seventy-two percent of patients had good to excellent results. There were no significant complications. Eighteen patients underwent surgery in an ambulatory setting and were discharged from hospital in a mean of 189 minutes. The procedure is safe and easily mastered. The staple line should be placed precisely at 3.5 to 4 cm from the dentate line to ensure greater efficacy.

Randomized clinical trial of Ligasure versus conventional diathermy for day-case haemorrhoidectomy

BACKGROUND

Haemorrhoidectomy is frequently associated with postoperative pain and prolonged hospital stay. A new technique of haemorrhoidectomy using the Ligasure device suited to day-case surgery is described. This technique was compared with conventional open diathermy haemorrhoidectomy.

METHODS

Forty patients with grade III or IV haemorrhoids were randomized to Ligasure (group 1) or conventional diathermy (group 2) haemorrhoidectomy. Operative details were recorded and patients recorded daily pain scores on a linear analogue scale. Follow-up was at 1, 3, 6 and 12 weeks to evaluate complications, return to normal activity, ongoing symptoms and patient satisfaction.

RESULTS

Reduced intraoperative blood loss (median (range) 0 (0-5) ml versus 20 (12-22) ml; P < 0.001) and a shorter operating time (10 (8-11) versus 20 (18-25) min; P < 0.001) was observed in group 1 compared with group 2. More patients in group 1 were discharged on the day of operation (18 of 20 versus 11 of 20; P < 0.05) and there was a trend towards lower postoperative pain scores on day 1 (group 1 median 5 (95 per cent confidence interval (c.i.) 2.6 to 6.8) versus group 2 7 (95 per cent c.i. 4.2 to 7.7); P = 0.36). There was no difference between the two groups in the degree of patient satisfaction or number of postoperative complications.

CONCLUSION

Ligasure diathermy may be used safely in the treatment of patients with grade III or IV haemorrhoids. It reduces intraoperative blood loss and operating time, and facilitates same-day discharge.

Randomized clinical trial of Ligasure versus open haemorrhoidectomy

BACKGROUND

Postoperative pain associated with open haemorrhoidectomy remains problematic. Haemorrhoidectomy performed using bloodless bipolar diathermy--Ligasure--may have advantages over conventional open haemorrhoidectomy in terms of operating time and postoperative pain.

METHODS

Thirty-four patients were randomized to undergo Ligasure (18 patients) or diathermy (16) haemorrhoidectomy. The operating time, amount of pain and postoperative analgesic requirement, postoperative complications and overall patient satisfaction were documented.

RESULTS

The median duration of operation was shorter in the Ligasure haemorrhoidectomy group (5.1 versus 9.2 min; P < 0.001). There was no statistically significant difference in the postoperative pain score, but the median analgesic requirement was lower in the Ligasure group (850 versus 1600 mg tramadol; P = 0.013). Patient satisfaction was similar in both groups.

CONCLUSION

Ligasure haemorrhoidectomy is quick and bloodless and, although as painful as diathermy haemorrhoidectomy, is associated with a reduced analgesic requirement.

Ligation-anopexy for treatment of advanced hemorrhoidal disease

PURPOSE

Destruction of the anchoring tissue system is considered to be the essential prerequisite to the pathogenesis of advanced hemorrhoidal disease. Ligation-anopexy was designed to 1) restore fixation of the hemorrhoidal cushions to the underlying internal sphincter, 2) reduce hemorrhoidal prolapse, and 3) minimize the hemorrhoidal blood flow. The purpose of this study was to evaluate the ligation-anopexy as a new technique for the treatment of advanced stages of hemorrhoidal disease.

METHODS

This study included 40 patients with hemorrhoidal disease (mean age 29.63 +/- 9.79 years, male/female ratio 34:6). Twenty-two patients had third-degree and 18 patients had fourth-degree hemorrhoids; of those with fourth-degree hemorrhoids, two patients had associated anal fissure and three patients had partial mucosal prolapse. Informed consent was obtained from all patients. After reduction of hemorrhoidal prolapse and under general or spinal anesthesia, a needle with 2-0 polyglactin (Vicryl) was inserted 1.5 cm above the dentate line using a Sims' speculum. The needle was inserted deep enough to fix the mucosa and the submucosa to the underlying internal sphincter. After the suture was tied, the redundant mucosa was pulled distally to be incorporated in the ligature, and the thread was relegated around it to form a mucosal tag.

RESULTS

Inclusion of a part of the internal sphincter with ligation of the redundant mucosa ensures adequate retraction of prolapsed hemorrhoids (hemorrhoid lift). Postoperative pain was accepted by 90 percent of the patients and disappeared after treatment with oral diclofenac. The immediate complications included anal spasm in 10 percent, postoperative bleeding in 2.5 percent, and thrombosis of the external hemorrhoids in 2.5 percent of patients. Neither recurrence nor anal stenosis was observed after 12 months of follow-up.

CONCLUSION

Despite the limited number of patients and the short follow-up, the preliminary results of ligation-anopexy in the treatment of advanced hemorrhoidal disease are encouraging.

Long-term effects of stapled haemorrhoidectomy on internal anal function and sensitivity

BACKGROUND

Stapled haemorrhoidectomy is gaining wide acceptance but there is still some concern about the risk of injury to the internal anal sphincter (IAS). IAS function and morphology, and anal canal sensitivity were studied prospectively in patients undergoing this operation.

METHODS

Twenty patients (11 women; mean age 43 years) with stage III haemorrhoids entered the study. All underwent preoperative anorectal manometry, rectoanal inhibitory reflex (RAIR) testing and three-dimensional transanal ultrasonography. A test of anal sensation was administered to evaluate ability to discriminate between air and warm water. All the investigations were repeated 6 months after the operation.

RESULTS

The mean(s.d.) maximal resting pressure was 87(30) mmHg before surgery and 81(20) mmHg afterwards (P not significant). The maximal squeeze pressure did not change after operation (178(43) versus 174(60) mmHg). The RAIR showed the same features in 19 of 20 patients before and 18 of 20 after operation. Three-dimensional ultrasonography demonstrated no changes in the width of the IAS (mean(s.d.) 2.1(4) mm before and 2.1(3) mm after surgery). The ability of the anal mucosa to discriminate air from warm water improved in five patients. Continence scores did not differ significantly after 6 months.

CONCLUSION

Stapled haemorrhoidectomy does not affect the function and morphology of the IAS in the long term. The sensitivity of the anal canal can improve in patients with preoperative sensory impairment.

Circular stapled anopexy for haemorrhoidal disease: results

OBJECTIVE

Stapled anopexy is a new approach for haemorrhoids requiring surgical treatment. This study reviews the available information concerning the present results of this procedure.

METHODS

Medline and hand search of the literature was conducted to identify available information on the procedure, with a special interest for the on-going or published randomized clinical trials.

RESULTS

The advantages of the stapled approach of haemorrhoids were analyzed in the different areas of concern, including postoperative pain reduction, length of hospital stay and sick-leave, postoperative wound care and type and rate of complications. Continence status, symptom cure and patient satisfaction following stapled anopexy are also reported.

CONCLUSION

Stapled anopexy is probably less painful than conventional haemorrhoidectomy. Other advantages in the short term result from this new approach. Long term efficacy of the procedure is still unknown.

Feasibility case-controlled study of day-case haemorrhoidectomy

INTRODUCTION

Haemorrhoidectomy is traditionally an inpatient procedure. With many benefits, the day-surgery arrangement is an attractive alternative. The feasibility of day-surgery haemorrhoidectomy was explored and the hospital days were calculated in a case controlled design.

METHODS

A single surgeon's experience of day-surgery haemorrhoidectomy between 1 July 1999 and 31 March 2000 was compared with inpatient haemorrhoidectomy during the same period. The operations were performed at United Christian Hospital Department of Surgery, Hong Kong (a government-funded public hospital). Statistical tests were applied where appropriate.

RESULTS

There were 30 day-surgery and 15 inpatient haemorrhoidectomies. The groups were comparable in terms of age, gender, severity of haemorrhoids, method and duration of haemorrhoidectomy, blood loss, residual haemorrhoids, duration of follow up and unplanned readmission rate. Significantly more day-patients received general than spinal anaesthesia. Twenty-six of 30 (87%) patients were successfully discharged after day surgery. Two were admitted for transient fever (< 24 h), one for micturition syncope and one for acute urinary retention. There were four unplanned readmissions after day surgery: one for pain and three for secondary bleeding. All stopped spontaneously. All three unplanned readmissions after inpatient surgery were for secondary bleeding. All stopped spontaneously. Patient stay was significantly shorter for day surgery (1 +/- 1 day) than for the inpatient arrangement (4 +/- 1.6 days).

CONCLUSION

Day-surgery haemorrhoidectomy is feasible. The significantly shorter hospital stay implies savings in public medical expenses.

Randomized trial assessing anal sphincter injuries after stapled haemorrhoidectomy

BACKGROUND

Conventional stapled haemorrhoidectomy involves the use of a large circular anal dilator (DL technique), which may cause anal sphincter injuries. This study compared whether the procedure can be effectively performed without this dilator (ND technique), with better sphincter preservation.

METHODS

Fifty-eight patients with symptomatic prolapsed irreducible haemorrhoids were randomized to DL (n = 29) and ND (n = 29) groups. Preoperative continence scoring, anorectal manometry and endoanal ultrasonography were performed. These were repeated at up to 14 weeks after operation, with additional pain scores, analgesic requirements and quality of life assessments.

RESULTS

DL haemorrhoidectomy took significantly longer to perform (P = 0.02). However, there were fewer residual skin tags (P = 0.044) and less perianal pruritus (P = 0.007) at 2 weeks, although such symptoms subsided to an equivalent level in both groups afterwards. Internal anal sphincter fragmentation persisting to at least 14 weeks was found in four patients after DL, but not after ND haemorrhoidectomy (P = 0.038). However, these were asymptomatic and no differences were found in continence scores and anal pressures. The pain scores, satisfaction scores, quality of life assessments and time off work were similar.

CONCLUSION

The large circular anal dilator used for stapled haemorrhoidectomy increased the risk of anal sphincter injuries, which may become problematic with ageing.

Randomized clinical trial of stapled versus Milligan-Morgan haemorrhoidectomy

BACKGROUND

The introduction of a stapling technique for the treatment of haemorrhoids has the potential for less postoperative pain, a short operating time and an early return to full activity. The outcome of stapled haemorrhoidectomy was compared with that of current standard surgery in a randomized controlled study.

METHODS

Two hundred patients were randomized to either stapled haemorrhoidectomy (n = 100) or Milligan-Morgan haemorrhoidectomy (n = 100) between March 1997 and December 1998. Each patient received standardized postoperative analgesic and laxative regimens, and completed a linear analogue pain score every 6 h during the first day after operation, after the first motion and daily until the end of the first week. Operating time, frequency of postoperative analgesic intake, hospital stay, time to return to normal activity and postoperative complications were also recorded.

RESULTS

The mean(s.d.) age of patients in the stapled and surgical groups was 44.1(3.2) and 49.1(12.2) years respectively. The stapled group had a shorter operating time, less frequent postoperative analgesia intake, shorter hospital stay and earlier return to normal activity. Early and late complications, and functional outcome were better in the stapled group.

CONCLUSION

Use of a circular stapler in the treatment of haemorrhoidal disease was safe, and was associated with fewer complications than conventional haemorrhoidectomy.

Treatment of hemorrhoids with circular stapler, a new alternative to conventional methods: a prospective study of 140 patients

BACKGROUND

Surgical hemorrhoidectomy has a reputation for being a painful procedure. The aim of this study was to determine the efficacy and safety of a new procedure for surgical treatment of hemorrhoid disease.

STUDY DESIGN

From April 1998 to August 1998, 140 patients (83 men and 57 women) with an average age of 43.8 years (range 19 to 83 years) underwent hemorrhoidectomy using a circular stapler. Operative times, pen- and postoperative complications, mean hospital stay, assessment of the postoperative pain, period of incapacity for work, and functional results were collected. All patients were evaluated at 2 weeks, 2 months, and 18 months after operation.

RESULTS

The average length of the operation was 18 minutes (range 8 to 60 minutes). There were no perioperative complications. The postoperative complication rate was 6.4% (n = 9). Mean hospital stay was 36 hours (range 8 to 72 hours). Paracetamol was the only analgesic used. Eighty-three patients (59.3%) required analgesic for less than 2 days, 45 patients (32.1%) between 2 and 7 days, and 12 patients (8.6%) more than 7 days. No patients had anal wound care. One hundred four patients had professions. The period of incapacity for work was less than 3 days for 22 patients (21.1%), between 3 and 7 days for 13 patients (12.5%), between 7 and 14 days for 62 patients (59.6%), and more than 14 days for 7 patients (6.8%). At 18 months, 95.7% of patients were fully satisfied with the results, 3.6% were somewhat satisfied (n = 4), and 0.7% were unsatisfied.

CONCLUSIONS

Treatment of hemorrhoids with a circular stapler appears to be safe, effective, and rapid, causing few postoperative complications and minimal postoperative pain. At 18 months, 95.7% of the patients were fully satisfied with the results.

Randomised controlled trial between stapled circumferential mucosectomy and conventional circular hemorrhoidectomy in advanced hemorrhoids with external mucosal prolapse

BACKGROUND

This randomized prospective study compared the outcome of circular hemorrhoidectomy according to the Hospital Leopold Bellan (HLB) technique (Paris) with Longo stapled circumferential mucosectomy (LSCM) in two homogeneous groups of patients affected by circular fourth-degree hemorrhoids with external mucosal prolapse.

METHODS

From December 1996 to December 1999, 80 consecutive patients with fourth-degree hemorrhoids and external mucosal prolapse were randomly assigned to two groups. Forty patients (group A: 18 men, 22 women, mean age 50.5 years, range 21 to 82) underwent HLB hemorrhoidectomy, and 40 patients (group B: 15 men, 25 women, mean age 51.0 years, range 29 to 92) underwent LSCM. Before surgery, all patients were selected with a standard questionnaire for symptom evaluation, full proctological examination, flexible rectosigmoidoscopy, dynamic defecography, and anorectal manometry. No significant differences among the two groups were found. All patients were controlled with follow-up questionnaire and with clinical examination at 1, 2, 4, 12, and 54 weeks after the operation. A postoperative manometry was performed 3 months after surgery.

RESULTS

The length of the operation was significantly lower in group B (25 +/- 3.1 SD versus 50 +/- 5.3 minutes, P <0.001). Mean hospital stay was 3 +/- 0.4 days in group A and 2 +/- 0.5 days in group B (P <0.01). Mean duration of inability to work was 8 +/- 0.9 days in group B and 15 +/- 1.4 days in group A (P <0.001). Postoperative pain was significantly lower in group B (P <0.001). Mean length of follow-up was 20 +/- 8.0 months in group A and 20 +/- 7.8 months in group B. Late complications were similar in the two groups, with 0%, at present, recurrence rate.

CONCLUSIONS

Our results confirm that both operations are safe, easy to perform, and effective in the treatment of advanced hemorrhoids with external mucosal prolapse. However, the LSCM seems to be preferable owing to the fewer postoperative complications, easier postoperative management, and shorter time to return to work. A longer follow-up is required to confirm the true efficacy of this surgical method.

Follow-up confirms sustained benefit of circumferential stapled anoplasty in the management of prolapsing haemorrhoids

BACKGROUND

Circumferential stapled anoplasty is gaining popularity as a safe and effective treatment in the surgical management of haemorrhoids and mucosal prolapse. However, little is known about the medium- and long-term durability of this procedure. The aim of this study was to evaluate the medium-term results of stapled anoplasty in maintaining symptom remission and to identify possible procedure-related adverse effects.

METHODS

Of a consecutive series of 85 stapled anoplasties in 83 patients, 64 patients were eligible for 6-month review; 50 patients were seen in surgical outpatient clinics and seven were contacted by telephone. All patients attending the outpatient clinic were questioned about current symptoms and overall satisfaction with the procedure. The staple line was palpated digitally and inspected at proctoscopy.

RESULTS

Median (interquartile range) symptom scores were 6 (5--8) before operation compared with 0 (0--1) at 6 months (P < 0.01). There was no deterioration in symptoms between 6-week and 6-month follow-up. No recurrences and no procedure-related adverse effects, in particular impaired continence or persistent anal pain, were identified.

CONCLUSION

The initial promising results of circumferential stapled anoplasty in effectively treating haemorrhoidal symptoms appear to be sustained at 6-month follow-up.

Early and late (ten years) experience with circular stapler hemorrhoidectomy

PURPOSE

We present a retrospective clinical study concerning the preliminary experience with the circular stapler in the treatment of hemorrhoids. Early results, complications, and long-term follow-up are revisited.

METHODS

Fifty-six consecutive patients with second-, third-, and fourth-degree hemorrhoids were included in the study. Data about operation, early postoperative results, and follow-up at one, two, and four weeks were collected. Patients were also contacted by phone after a long-term follow-up (mean, 33 (range, 5-120) months).

RESULTS

Every operation attempted was successfully terminated. The length of the operation was less than 15 minutes. No major bleeding or anastomotic disruption occurred. Six patients (13 percent) who underwent spinal or epidural anesthesia had urinary retention. One patient (1.7 percent) had minor bleeding, and four patients (7.1 percent) experienced transient edema of the anastomotic ring after the operation. None needed further treatments. The mean analgesic requirement was 1.4 (range, zero to eight) ketorolac 30-mg injections; 23 patients (41 percent) received no analgesics, and seven patients (12 percent) required a single extra dose of opiates (10 mg morphine cloridrate). Length of hospital stay was between 0 and 11 (mean, 2.7) days, but 20 patients (35 percent) received an additional operation for coexisting surgical disease. At one week, almost all patients experienced little pain at digital inspection and little bleeding after defecations. No anastomotic leakage, wound infection, or healing delay was found. Three patients (5.3 percent) experienced wound edema and pain during defecation. Two weeks later, one patient (1.7 percent) suffered from painful defecation and ten patients (17 percent) reported minor bleeding, but all returned to normal activities. No pain during defecation, bleeding, stenosis, soiling, incontinence, or other anal symptoms were found at one month after the operation, and all patients were well. All patients were contacted by phone 5 to 120 (mean, 33) months later, and all were pleased with the results of this procedure. There were no symptomatic recurrences.

DISCUSSION

Our study confirms the feasibility of circular stapler hemorrhoidectomy in the treatment of hemorrhoids. Complications and postoperative pain were minimal. There were no recurrences during long-term follow-up.

CONCLUSION

Mechanical hemorrhoidectomy is a promising new option in the treatment of all patients eligible for a surgical approach.

Day surgery for mucosal-hemorrhoidal prolapse using a circular stapler and modified regional anesthesia

PURPOSE

In 1993, prolapse reduction using the circular stapler for the treatment of hemorrhoidal disease was proposed. The procedure is characterized by minimal postoperative pain. In this study we evaluated the above technique using regional anesthesia to identify the advantages and feasibility of stapled hemorrhoidectomy, with special focus on the efficacy of same-day discharge.

METHODS

From December 1997 to November 1999, we performed 70 consecutive reduction corrections of mucosal hemorrhoidal prolapse using the circular stapler with regional anesthesia (a technical modification of Marti's posterior perineal block). Our series included 41 males and 29 females with a mean age of 43.4 (range, 25-74) years. Three patients were affected by second-degree hemorrhoids and 67 by third-degree hemorrhoids.

RESULTS

Sixty-two patients were discharged three hours after the operation in good general condition and without pain, whereas eight patients were discharged the day after for early complications, consisting of two cases of early bleeding, three cases of urinary retention, and three cases of persistent severe pain requiring prolonged medical treatment.

CONCLUSION

Our study shows that, in selected cases, it is possible to perform day surgery for patients with hemorrhoidal disease using a circular stapler device when combined with regional anesthesia.
