At the crossroads of venous insufficiency and hemorrhoidal disease: Daflon 500 mg--repercussions of venous insufficiency on everyday life.

A research program has been developed to define an evaluation tool capable of assessing the impact of venous insufficiency and its treatments on the patient's everyday life. The methodology is described in the first part of this paper, followed by the results of the first phase of the research program, based on two surveys: a "qualitative" survey in a population of severely affected patients and a "quantitative" survey in a population of 150 patients.

[Histostructure of the venous bed of the hemorrhoidal zone of the human rectum].

In 90 preparations of the human rectum, venous vessels were studied. In all age groups, newborns and children including, trabecular veins with cone-shaped protrusions, intimal "cushons" and microvalves were revealed. In the columnar zone, on the lateral walls of the anal canal, they form cavernous bodies in arterio-venous anastomoses. In elderly and old-aged persons, as a result of myoelastofibrosis, thinning of the cavernous vein walls and partial hollowing of their lacunae take place.

A prospective, randomized, controlled multicenter trial comparing stapled hemorrhoidopexy and Ferguson hemorrhoidectomy: perioperative and one-year results.

PURPOSE: There is a growing body of evidence supporting the lesser degrees of pain with stapled hemorrhoidopexy, also called the procedure for prolapse and hemorrhoids. However, there have been few randomized comparisons assessing both perioperative and long-term outcomes of the procedure for prolapse and hemorrhoids and Ferguson hemorrhoidectomy. Results are presented here from the first prospective, randomized, multicenter trial comparing these hemorrhoid procedures in the United States. METHODS: Patients with prolapsing hemorrhoids (Grade III) were randomized to undergo the procedure for prolapse and hemorrhoids or Ferguson hemorrhoidectomy by colorectal surgeons who had training in using the stapling technique. Primary end points were acute postoperative pain, and hemorrhoid symptom recurrence requiring additional treatment at one-year follow-up from surgery. RESULTS: A total of 156 patients (procedure for prolapse and hemorrhoids, 77; Ferguson, 79) completed randomization and the surgical procedure, 18 (procedure for prolapse and hemorrhoids, 12; Ferguson, 6) had significant protocol violations. One hundred seventeen patients (procedure for prolapse and hemorrhoids, 59; Ferguson, 58) returned for one-year follow-up. Demographic parameters, hemorrhoid symptoms, preoperative pain scores, and bowel habits were similar between groups. There were a similar number of patients with adverse events in each group (procedure for prolapse and hemorrhoids, 28 (36.4 percent) vs. Ferguson, 38 (48.1 percent); P = 0.138). Reoperation for an adverse effect was required in six (7.6 percent) Ferguson patients and in 0 patients having the procedure for prolapse and hemorrhoids (P = 0.028). Postoperative pain during the first 14 days, pain at first bowel movement, and need for postoperative analgesics were significantly less in the procedure for prolapse and hemorrhoids group. Control of hemorrhoid symptoms was similar between groups; however, significantly fewer patients having the procedure for prolapse and hemorrhoids required additional anorectal procedures during one-year follow-up (procedure for prolapse and hemorrhoids, 2 (2.6 percent), vs. Ferguson, 11 (13.9 percent); P = 0.01). Only four of the Ferguson patients (5 interventions) required additional procedures more than 30 days after surgery. CONCLUSIONS: These data demonstrate that stapled hemorrhoidopexy offers the benefits of less postoperative pain, less requirement for analgesics, and less pain at first bowel movement, while providing similar control of symptoms and need for additional hemorrhoid treatment at one-year follow-up from surgery.

Hemorrhoidectomy: indications and risks.

Hemorrhoids are a common cause of perianal complaints and affect 1-10 million people in North-America and with similar incidence in Europe. Symptomatic hemorrhoids are associated with nutrition, inherited predisposition, retention of feces with or without chronic abuse of laxatives or diarrhea. Increased pressure and shearing force in the anal canal may lead to severe changes in topography with detachment of the hemorrhoids from the internal sphincter and fibromuscular network resulting in bleeding, itching, pain and disordered anorectal function, even incontinence. The significance of hemorrhoids for anal continence (corpus cavernosum) is recognized. In most instances, hemorrhoids are treated conservatively; the surgeon is contacted when conservative measures have failed or complications, e.g., thrombosis, have occurred. 4 degrees prolapsed internal hemorrhoids are the main indication for hemorrhoidectomy: high (Parks) or low (Milligan-Morgan) ligation with excision, closed hemorrhoidectomy (Ferguson) or stapler hemorrhoidectomy. Thrombosed external hemorrhoids are primary treated by incision and secondary by excision. Complications after operative treatment of external thrombosed hemorrhoids are rare. After standard hemorrhoidectomy for internal hemorrhoids approximately 10% may have a complicated follow-up (bleeding, fissure, fistula, abscess, stenosis, urinary retention, soiling, incontinence); there may be concomitant disease, e.g., perianal cryptoglandular infection, causing complex fistula/abscess, which is associated with an increased risk (30-80%) for complications, e.g., incontinence. Other treatment options, e.g., sphincterotomy, anal stretch, have been accused to cause more complications, e.g., incontinence in 30-50% of cases. However, incontinence is a complex phenomenon; it is evident that an isolated single injury is normally not a sufficient cause, e.g., injury of the internal sphincter. The majority of patients may present with prior obstetric injury, perianal infection or Crohn's disease and other comorbidity. Therefore all systemic and regional disorders, causing incontinence, should be excluded before starting manometric, neurophysiological and sonographic investigations. Variation and overlap in test results, patient-, instrument- or operator-dependent factors ask for cautious interpretation. There is vast evidence that the demonstration of muscle fibers in hemorrhoidectomy specimens is a normal feature. In conclusion, standard hemorrhoidectomy with proper indication is a safe procedure. If complications occur, it is in the interest of the patient and surgeon to perform a thorough investigation.

Sustained internal sphincter hypertonia in patients with chronic anal fissure.

PURPOSE: This study was designed to determine whether functional variations of internal sphincter activity occur in order to differentiate between patients with anal fissures from those with hemorrhoids. METHODS: Thirty patients with chronic anal fissure (median age, 28 years; 12 females), 22 patients with hemorrhoids (median age, 37 years; 7 females), and 33 control volunteers (median age, 48.5 years; 21 females) underwent ambulatory anal sphincter fine-needle electromyography and anorectal manometry. RESULTS: The median internal sphincter electromyography frequency was similar: fissure group, 0.49 Hz; hemorrhoid group, 0.46 Hz (P > 0.05), and control group, 0.44 Hz (P > 0.05). Median anal resting pressures were similar in the fissure group (132 cm. H2O) and the hemorrhoids group (116 cm of H2O) (P > 0.05), but significantly greater than those in the control group (94 cm. H2O) (P < 0.05). The median number of transient relaxations of the internal and sphincter with an associated rise in rectal pressure and fall in anal pressure was 1 (range, 0-4) per hour in the fissure group, 6 (range, 4-7) per hour in the hemorrhoid group, and 4 range, 3-6) per hour in the control group. Six patients with fissures were reassessed following lateral internal sphincterotomy. Median and pressure was 102 cm of H2O (P > 0.1 vs. controls) and the number of internal sphincter relaxations increased to 4 per hour (P < 0.01 vs. preoperative number). CONCLUSIONS: Internal anal sphincter relaxation occurs on fewer occasions in patients with chronic anal fissures that have failed to heal in comparison to patients with hemorrhoids and normal controls. This evidence further supports the hypothesis that internal sphincter hypertonia may be relevant to the pathogenesis of this disorder.

Submucosal reconstructive hemorrhoidectomy (Parks' operation): a 20-year experience.

BACKGROUND: Submucosal reconstructive hemorrhoidectomy has never been a popular operation due to its difficulty and duration, the amount of blood loss, and the risk of incontinence. The main indication for hemorrhoidectomy according to Parks is fourth-degree hemorrhoids with prolapse of the dentate line outside the anus and with simultaneous presence of external hemorrhoids. We report our experience in the treatment of hemorrhoids using submucosal reconstructive hemorrhoidectomy according to Parks. METHODS: A total of 640 patients (381 men and 259 women) of median age 42 years (range, 18-81) were treated between 1983 and 2002; 80% of patients had fourth-degree, 19% third-degree and 1% second- degree hemorrhoids. All patients underwent rectosigmoidoscopic examination before surgery; patients over 35 years of age or with a suspected inflammatory or neoplastic disease underwent colonoscopy or barium enema. All patients underwent anorectal manometry before operation, to measure anal resting pressure, maximal squeeze and sphincter length, with the purpose of determining if an internal sphincterotomy was also necessary (in case of high anal resting tone). One-third of the patients also had an internal sphincterotomy to correct anal hypertonia. RESULTS: Postoperative bleeding occurred in 19 patients (2.9%), 0.9% requiring a reintervention. Severe pain was reported by 9 patients (1.4%); fecal impaction occurred in 3 cases (0.5%) and suture disruption in 2 patients (0.3%). In 74 patients (11.6%), bladder catheterization was needed due to urinary retention. Of 550 patients who had a minimum follow-up of 3 years and were sent a postal questionnaire, 374 patients responded, with a median 7.3-year follow- up; 176 patients (32%) were lost to follow-up. Eleven patients (2.9% of 374 cases) reported pain during defecation, 6 (1.6%) developed skin tags or recurrence, 3 (0.8%) reported gas incontinence, 2 (0.5%) developed anal fistula and 1 (0.3%) had anal stricture. CONCLUSIONS: Submucosal reconstructive hemorrhoidectomy according to Parks still represents a good choice for the treatment of high-degree hemorrhoids with prolapse of the dentate line outside the anus and external circumferential hemorrhoids.

Resting anal pressure following hemorrhoidectomy and lateral sphincterotomy.

PURPOSE: The role of high anal pressure in the pathophysiology of hemorrhoids and anal fissures is debated. We compared resting anal pressures following left lateral sphincterotomy and hemorrhoidectomy in a prospective manometric study with emphasis on the recovery of the internal anal sphincter activity. METHODS: Included in the study were 38 patients with third-degree or fourth-degree symptomatic hemorrhoids who underwent hemorrhoidectomy, 50 patients with anal fissure who underwent sphincterotomy, and 12 healthy patients who served as controls. All patients with anal fissure or hemorrhoids underwent periodic manometric evaluation: 1 month before surgery and 1, 3, 6, and 12 months after surgery. The control group had three manometric evaluations 6 months apart. RESULTS: Baseline pressure measurement in the fissure group was significantly higher than in the hemorrhoid group, which was significantly higher than in the control group (138 +/- 28.4 mmHg vs. 108.4 +/- 23 mmHg vs. 73 +/- 5.9 mmHg, P < 0.0001). Twelve months after surgery, anal resting pressure remained significantly lower than the baseline measurements in both the fissure (110 +/- 18.2 vs. 138 +/- 28.4, P < 0.0001) and hemorrhoid groups (103.6 +/- 21.5 vs. 108 +/- 23, P < 0.0001), but both remained higher than the control group (103.6 +/- 21.5 mmHg vs. 73 +/- 5.9 mmHg, P < 0.0001). CONCLUSIONS: Resting pressure is elevated in hemorrhoid and anal fissure patients. After surgery the anal resting pressure is reduced but is still higher than in the control group. Further studies are required to investigate the protective effect of postsurgical reduction of anal resting pressure against recurrence.

Long-term results after stapled hemorrhoidopexy: high patient satisfaction despite frequent postoperative symptoms.

PURPOSE: Stapled hemorrhoidopexy has been demonstrated to be advantageous in the short term compared with the traditional techniques. We aimed to evaluate long-term results after stapled hemorrhoidopexy and to assess patient satisfaction in association with postoperative hemorrhoidal symptoms. METHODS: This prospective study included 216 patients with Grade 2 or 3 hemorrhoids, who had stapled hemorrhoidopexy using the circular stapled technique. The results were evaluated by a standardized questionnaire at least 12 months after the operation. The primary end point was patient satisfaction; secondary end points included specific hemorrhoidal symptoms. RESULTS: Followup data were obtained for 193 of 216 patients (89 percent) with a median follow-up of 28 (range, 12-53) months, most of whom (89 percent) were satisfied or very satisfied with the surgery. The main preoperative symptom was no longer present postoperatively in 66 percent of patients, was relieved in 28 percent, and had worsened in 2 percent. Postoperative complaints included symptoms of hemorrhoidal prolapse (24 percent of patients), anal bleeding (20 percent), anal pain (25 percent) fecal soiling/leakage (31 percent), fecal urgency (40 percent), and local discomfort (38 percent). Bivariate analysis showed significant associations between each of these symptoms and patient satisfaction. Nine patients (5 percent) were reoperated on during the follow-up period. CONCLUSIONS: Long-term patient satisfaction was high in most of patients after stapled hemorrhoidopexy for second-degree and third-degree hemorrhoids. However, an unsatisfactory outcome was significantly related to postoperative hemorrhoidal symptoms such as prolapse, fecal soiling/leakage, and new onset of fecal urgency.

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.
