Histopathology of stapled haemorrhoidectomy specimens: a cautionary note

Association of Muscle Fibers with Histopathology in Doughnut Specimens Following Stapled Hemorrhoidopexy and Their Impacts on Postoperative Outcomes

Background Stapled hemorrhoidopexy is widely practiced worldwide since its introduction to the world of proctology and replaced conventional hemorrhoidectomy in treating hemorrhoids. The technique of executing the procedure dictates the outcomes and complications. Here, we attempted to establish the cause of postoperative complications and attributed them to the presence of muscle of fibers in the excised doughnut specimens.

Materials and Methods A prospective observational analysis of histopathological specimens obtained from patients who underwent stapled hemorrhoidopexy using procedure for prolapse and hemorrhoids-03 circular staplers in the department of surgery of a tertiary care hospital in southern India was performed, and the correlation between the presence or absence of muscle fibers in the specimens and postoperative complications was evaluated. The patients were followed up for 12 months after the procedure.

Results In this study, 155 patients, including 54, 91, and 10 patients with Grade 2, Grade 3, and Grade 4 hemorrhoids, respectively, were included. Group A consisted of 19 patients with muscle fibers on the specimens, whereas Group B consisted of 139 patients without muscle fibers on the specimens. Early complications within 7 days after the procedure were as follows: 21 and 0.7% of the patients in Groups A and B, respectively, presented with postoperative pain with a visual analog scale score of more than 4; 47 and 6% of the patients in Groups A and B, respectively, presented with urinary retention; 26 and 2% of the patients in Groups A and B, respectively, presented with bleeding; and 21 and 2.9% of the patients in Groups A and B, respectively, presented with fecal urgency. A significant association was found between the presence of muscle fibers and early complications (p < 0.001). Late complications, such as proctalgia and bleeding, accounting for 36.8 and 6.6% in Groups A and B, respectively, were significantly associated with the presence of muscle fibers in histopathology (p < 0.001). Meanwhile, other late complications, such as incontinence, stenosis, and recurrence, exhibited no association (p > 0.05).

Conclusion The technique in taking purse-string sutures and the depth of the suture bite above the dentate line carry the utmost importance in preventing postoperative complications. Therefore, surgeons should refine their technique of appropriate depth to avoid incorporation of muscle fibers while executing the procedure.

Stapled haemorrhoidopexy: is it time to move on?

Stapled haemorrhoidectomy was proposed as an 'ideal' solution for symptomatic haemorrhoids, with minimal postoperative pain, no perianal wound requiring postoperative wound care and a relatively short operative time. Some randomised controlled trials and reviews confirmed these findings, claiming that stapled haemorrhoidopexy is the most effective and safe procedure for haemorrhoids. However, there are increasing number of publications highlighting that the technique is associated with serious and life threatening complications. Maybe it is now the time to accept that stapled haemorrhoidopexy has done its role in directing our attention to the fact that modern surgical treatment of haemorrhoids should avoid excision of anorectal skin but should instead aim at treatment intervention above the dentate line.

Correlation of histopathology with anorectal manometry following stapled hemorrhoidopexy

Purpose

The removal of smooth muscle during stapled hemorrhoidopexy raises concerns regarding its effects on postoperative anorectal function. The purpose of this study was to evaluate the correlation between the amount of muscle removed and changes in anorectal manometry following stapled hemorrhoidopexy.

Methods

Patients with symptomatic II, III, or IV degree hemorrhoids that underwent stapled hemorrhoidopexy between January 2008 and May 2011 were included in this study. Anorectal manometry was performed preoperatively and at three months postoperatively. The resected doughnuts were examined histologically, and the thicknesses of muscle fibers were evaluated.

Results

Eighty-five patients (34 males) with a median age of 47 years were included. Muscularis propria fibers were identified in 63 of 85 pathologic specimens (74.1%). The median thickness of the muscle fibers was 1.58 ± 1.21 mm (0 to 4.5 mm). The mean resting pressure decreased by approximately 7 mmHg after operation in the 85 patients (P = 0.019). In patients with muscle incorporation, there was a significant difference in mean resting pressure (P = 0.041). In the analysis of the correlation of the difference in anorectal manometry results ([the result of postsurgical anorectal manometry] - [the result of presurgical anorectal manometry]) to the thickness of muscle fibers, no significant differences were seen. No patients presented with fecal incontinence.

Conclusion

Although the incidence of fecal incontinence is very low, muscle incorporation in the resected doughnuts following stapled hemorrhoidopexy may affect anorectal pressure. Therefore, surgeons should endeavor to minimize internal sphincter injury during stapled hemorrhoidopexy.

Clinical outcomes of stapled transanal rectal resection (STARR) for obstructed defecation syndrome (ODS): a single institution experience in South Korea

PURPOSE

The purpose of this study was to assess both the short- and long-term functional outcomes of stapled transanal rectal resection (STARR) in ODS patients.

PATIENTS AND METHODS

We performed a retrospective review of data that were collected from January 2005 to October 2008. Between January 2005 to June 2006, 58 patients who underwent STARR were enrolled in this study. Follow-up was scheduled for 3 months and 1 year after surgery with the Cleveland Clinic Florida (CCF) constipation score and satisfaction grade. To evaluate the long-term functional outcome, we interviewed the patients by telephone using questionnaires for the CCF score and satisfaction grade on October 2008.

RESULTS

The median follow-up period was 34 months (range, 27-46 months). The mean age and sex ratio were 54 years (range, 19-85 years) and 8:50 (M/F). The mean CCF constipation scores were 17.6 before the surgery, 9.5 at 3 months, 9.6 at 12 months, and 10.3 at the time of the latest interview. The satisfaction grade, which was rated as excellent and good by 63.4% of the patients at the time of the latest interview, was worse than that at 3 months (37.8%). Among the cases of the excellent group (19 cases) at postoperative 3 months, 13 cases (68.4%) were classified as excellent or good at the time of the latest interview.

CONCLUSION

The STARR is a safe and effective surgical procedure for restoring the anatomy and function in ODS patients. Strict selection of patients is needed in enhancing and maintaining the patients' satisfaction after the procedure.

Long-term clinical results of double-pursestring stapled hemorrhoidopexy in a selected group of patients for the treatment of chronic hemorrhoids

BACKGROUND AND OBJECTIVE

The aim of this prospective controlled trial was to evaluate the long-term clinical and manometric results of stapled hemorrhoidopexy performed by expert surgeons in a selected group of patients for the treatment of chronic hemorrhoids.

SETTINGS

This study took place in the outpatient clinic and at the Day Surgery Unit attached to the University Hospital of Elche.

PATIENTS

From March 2003 to May 2005, 200 consecutive patients with third-degree hemorrhoids and treated with double-pursestring stapled hemorrhoidopexy with a PPH33-03 stapler were included in the study.

MAIN OUTCOME MEASURES

Demographic, manometric, and clinical features were analyzed, as well as the variables related to surgery, postoperative course, and follow-up. Manometry was repeated at the 6-month, 1-year, and 5-year follow-up.

RESULTS

Median follow-up was 110 months. Four patients (2%) reported daily rectal bleeding. One patient with active rectal bleeding was taken for reoperation within the first 12 postoperative hours. Seventy percent of patients reported pain ≤ 2 on the first postoperative day, 85% on the fourth postoperative day, and 95% on the seventh postoperative day. Pain was measured with a linear analog scale from 0 to 10 (0 = no pain; 10 = unbearable pain). Seventeen patients (8.5%) reported tenesmus during the first week. Eight patients (4%) reported persistent pain: in 5 patients, the pain resolved within the next 6 months; 2 patients presented with anal fissure; and 1 patient required the removal of the staples. Two patients (1%) reported residual soiling at the 5-year revision. Fourteen patients (7%) experienced recurrence with symptomatic prolapse. Six (3%) underwent further surgery: stapled hemorrhoidopexy was indicated again in 2 patients, and 4 patients underwent a Milligan-Morgan open hemorrhoidectomy, because they did not have a uniform prolapse. Six patients required treatment with rubber band ligation. There were no statistically significant differences between preoperative and postoperative manometric values.

CONCLUSIONS

The new PPH33-03 stapler, the learning process of the modified surgical procedure, and the correct selection of patients will overcome the main objections to stapled hemorrhoidopexy.

Rectal distensibility and symptoms after stapled and Milligan-Morgan operation for hemorrhoids

INTRODUCTION

In a previous uncontrolled study, a reduction of rectal distensibility and volume thresholds for sensations have been related to the occurrence of fecal urgency and/or increased stool frequency after stapled hemorrhoidopexy.

AIM OF THE STUDY

The aim of this study was to compare rectal symptoms and sensory-motor function after stapled hemorrhoidopexy and Milligan-Morgan hemorrhoidectomy.

METHODS

The clinical records of 12 (four women) and ten patients (four women) with third- and fourth-degree hemorrhoids, respectively, who underwent stapled hemorrhoidopexy or Milligan-Morgan's hemorrhoidectomy, were evaluated. One week before and 6 months after surgery, rectal motor and sensory response to distension was assessed by an electronic barostat, and bowel and rectal symptoms were recorded by means of a 7-day diary and Bristol Index scale and psychological symptoms with SCL-90 questionnaire.

RESULTS

Rectal distensibility and volume thresholds for sensations were significantly lower after surgery (P < 0.02) in the stapled group. Increased stool frequency and/or fecal urgency arose in 41% of patients in the stapled group and associated with altered rectal distensibility. No difference within and between groups could be demonstrated in SCL-90 score.

CONCLUSIONS

Rectal distensibility and volume thresholds for sensations decrease after stapled hemorrhoidopexy. Altered rectal distensibility was associated with rectal urgency and/or increased stool frequency.

Stapled haemorrhoidopexy for the treatment of haemorrhoids: a systematic review

OBJECTIVE

This systematic review aimed to evaluate the short- and long-term safety, efficacy and costs of stapled haemorrhoidopexy (SH) compared with conventional haemorrhoidectomy.

METHOD

We searched 26 electronic databases and websites for studies in any language up to July 2006. Inclusion criteria were predefined, and each stage of the review process was conducted in duplicate.

RESULTS

Twenty-seven randomized controlled trials were included (n = 2279). All had some methodological flaws. Postoperatively, 19 trials (95%) reported less pain, 17 (89%) reported a shorter operating time, 14 (88%) a shorter hospital stay, and 14 (93%) a shorter convalescence time following SH. However, prolapse was significantly more common after SH (OR 3.38; 95% CI: 1.00, 11.47). In the longer term, prolapse was significantly more common after SH (OR 4.34; 95% CI: 1.67, 11.28) as was reintervention for prolapse (OR 6.78; 95% CI: 2.00, 23.00). There were no differences in the rate or type of complications. Conventional haemorrhoidectomy and SH had similar costs during the initial admission.

CONCLUSION

Compared with conventional haemorrhoidectomy, SH resulted in less postoperative pain, shorter operating time, a shorter hospital stay, and a shorter convalescence, but a higher rate of prolapse and reintervention for prolapse.

Prospective multicentre clinical trial of stapled transanal rectal resection for obstructive defaecation syndrome

BACKGROUND

This prospective multicentre study assessed the safety and effectiveness of stapled transanal rectal resection (STARR) for treatment of obstructive defaecation syndrome (ODS).

METHODS

Between February 2001 and June 2006, 104 patients diagnosed with ODS were treated with STARR. Follow-up was scheduled for 1, 3 and 6 months after surgery, and annually thereafter. Variables related to the patient, surgical technique and outcome were analysed.

RESULTS

Mean operating time was 46.7 min. Haemorrhage at the staple line occurred in 55 patients (52.9 per cent). Three patients required surgical revision in the first 48 h owing to persistent bleeding. The median postoperative pain score was 2.4 on a scale from 1 to 10. Mean hospital stay was 2.2 days. The mean constipation score improved from 13.5 before surgery to 5.1 at 1-year follow-up (P = 0.006). Twenty-three patients reported faecal incontinence at 4 weeks after surgery, but only nine still had minor residual incontinence by 1 year. At a median follow-up of 26 (range 12-72) months, ODS had recurred or persisted radiologically and/or clinically in 11 patients.

CONCLUSION

STARR is associated with low morbidity and a short hospital stay, and is an effective alternative treatment for ODS.

Reinterventions for specific technique-related complications of stapled haemorrhoidopexy (SH): a critical appraisal

INTRODUCTION

Stapled haemorrhoidopexy (SH) is an attractive alternative to conventional haemorrhoidectomy (CH) because of reduced pain and earlier return to normal activities. However, complication rates are as high as 31%. Although some complications are similar to CH, most are specifically technique-related. In this prospective audit, we report our experience with the management of some of these complications.

METHODS

Data on patients undergoing SH at our unit or referred to us are prospectively entered in a database. The onset or duration of specific SH-related complications as well as reinterventions for failed or complicated SH was recorded.

RESULTS

From 1/03 to 10/07, 110 patients underwent SH, while 17 patients were referred after complicated/failed SH. Overall early and late complication rates after SH were 12.7% and 27.2%, respectively. Overall reintervention rate was 9.1%. Among the referred SH-group, one patient underwent Hartmann's procedure because of rectal perforation. The remaining 16 patients experienced at least one of the following: recurrence, urgency, frequency, severe persistent anal pain, colicky abdominal pain, anal fissure and stenosis. Four patients underwent CH with regular postoperative recovery. Two patients underwent exploration under anaesthesia because of persisting pain. One patient underwent anoplasty.

CONCLUSIONS

SH presents unusual and challenging complications. Abuses should be minimized and longer-term studies are needed to further clarify its role.

Evaluation of rectal sensory and motor function by means of the electronic barostat after stapled hemorrhoidopexy

PURPOSE

Stapled hemorrhoidopexy is designed to replace the hemorrhoids into the anal canal by excising the redundant rectal mucosa above the anorectal ring, thus resulting in an intrarectal suture. Few studies have evaluated rectal function after this procedure. This prospective study was designed to use the electronic barostat to assess whether rectal motor and sensory functions change after stapled hemorrhoidopexy.

METHODS

Ten patients (4 women, mean age, 46 +/- 9 years) with third-degree and fourth-degree hemorrhoids who underwent stapled hemorrhoidopexy were studied. One week before and six months after surgery, they underwent three different rectal distensions (pressure-controlled stepwise, volume-controlled stepwise, and ramp) controlled by an electronic barostat.

RESULTS

Rectal distensibility was significantly lower after surgery during pressure stepwise (P = 0.01), during volume stepwise (P = 0.006), and during ramp distension (P = 0.001). Volume thresholds for desire to defecate, urgency, and discomfort were significantly lower after surgery during all three distensions (P < 0.05). Volume threshold for first perception also was significantly lower after surgery during volume ramp distension (P = 0.01).

CONCLUSIONS

Rectal distensibility and volume thresholds for sensations decrease after stapled hemorrhoidopexy. These impairments persist for at least six months after surgery.

The management of haemorrhoids

Haemorrhoidal disease is common, but there is still no consensus on optimal treatment. The most appropriate treatment is tailored to the individual patient. This article defines and classifies haemorrhoids, reviewing the efficacy of current treatments including the latest techniques.

Stapled hemorrhoidopexy: a technique for applying the crucial purse string suture (MAMC Technique)

BACKGROUND

Stapled hemorrhoidopexy for prolapsing hemorrhoids has been found to be associated with lesser postoperative pain and consequently earlier mobilization and return to work, in comparison to conventional hemorrhoidectomy. Purse string application remains a crucial step to ensure adequate lifting of the anal mucosa and this step is technically tedious in the presence of large hemorrhoids obscuring the vision using the standard purse string applicator. The proposed method in our technique makes this crucial step more reliable, easier, and safe in the hands of the beginner and the experienced surgeon alike.

METHODS

Thirty healthy adults (21 males and 9 females) with grade 3 or 4 hemorrhoids underwent stapled hemorrhoidopexy at a large university referral hospital in New Delhi. Purse string application was the first step in the entire procedure even before the application of the circular anal dilator. The purse string was applied using authors' method herein after referred to as Maulana Azad Medical College "(MAMC) technique" after the name of the institution. Rest of the procedure was completed as described by Longo et al.

RESULTS

The mean operative time was 26 minutes (range 16 to 40 min). The mean visual analog scale (VAS) pain score on day 1 was 1.6 (range 0 to 3). The mean hospital stay was 1.1 days (range 1 to 2 d). There was no major intraoperative complication and one case each of postoperative urinary retention and residual hemorrhoid, there was no recurrence, anal stenosis, or anal incontinence after a mean follow up of 15 months (range 3 to 24 mo).

CONCLUSIONS

The procedure described is safe, easy to learn, and technically sound, enabling the application of the crucial purse string at the desired distance from the dentate line, in the correct submucosal plane with closely placed bites and at the same transverse level.

Stapled hemorrhoidopexy: a prospective study from pathology to clinical outcome

Stapled hemorrhoidopexy is widely accepted to treat hemorrhoids, but serious complications have been reported. In this prospective audit, we correlated clinical outcome with pathological findings. From January 2003 to April 2007, 94 patients underwent hemorrhoidopexy. Macroscopic appearance of the specimen (shape, size, and depth) was recorded. Microscopically, the presence of columnar, transitional, and squamous epithelium, the involvement of circular/longitudinal smooth muscle, and features of mucosal prolapse were assessed. Clinical outcome was evaluated by a validated questionnaire. Postoperative pain, secretion, and bleeding durations were 12.7+/-10.6, 5.6+/-9.6, and 6.3+/-8.4 days. Patient's return to work averaged 16.7+/-10.7 days. Fissure, skin tags, and anal strictures were observed in 23.4%. Seven patients experienced pain for a significantly longer period of time. All specimens contained columnar mucosa, but 29.8% contained columnar and transitional epithelium and 12.8% contained columnar, anal transitional, and stratified squamous epithelium. Smooth muscle was observed in 62.7%. Pain was significantly increased if transitional epithelium was present in the specimen. No correlation or differences were observed if smooth muscle was present, although postoperative bleeding was more frequent. Hemorrhoidopexy is safe and effective. The specimen should always be sent for pathology examination. Only columnar epithelium should be present and, although the presence of smooth muscle does not influence the outcome in terms of functional results, its presence may play a role in postoperative bleeding.

Uncontrollable Intra-Abdominal Bleeding Necessitating Low Anterior Resection of the Rectum After Stapled Hemorrhoidopexy: Report of a Case

Stapled hemorrhoidopexy (SH) has become a widely accepted surgical procedure for hemorrhoids; however, one of the most serious complications of this technique is severe bleeding. We report a case of extensive hemoperitoneum after SH for third-degree hemorrhoids. On postoperative day (POD) 1, the patient complained of severe abdominal pain and clinical signs of peritonitis soon became evident. Computed tomography (CT) showed blood in the abdomen. We performed an emergency exploratory laparotomy, which revealed extensive hemoperitoneum, and a devitalized, edematous rectum with a tense hematoma, approximately 1 cm above the staple line and extending up to the level of the peritoneal reflection. We also found a small seromuscular laceration in the anterior aspect of the rectum just above the peritoneal reflection. This small laceration was bleeding actively. Thus, we performed a low anterior resection and the patient was discharged from hospital 10 days later. We report this case to raise awareness of the possibility of life-threatening intra-abdominal complications without evidence of typical rectal bleeding.

Evaluation of the stapled transanal rectal resection technique with two staplers in the treatment of obstructive defecation syndrome

BACKGROUND

This study was designed to assess the safety and effectiveness of stapled transanal rectal resection (STARR) and to compare the results of two staplers.

STUDY DESIGN

From February 2001 to June 2005, 37 patients diagnosed with obstructive defecation syndrome were treated with the STARR technique. We analyzed variables related to the patient, diagnosis based on anorectal exploration, surgical technique used, and clinical and radiologic results. We compared these results in patients with procedure prolapsed hemorrhoids (PPH)33-01 (group 1, n = 17) or PPH33-03 (group 2, n = 20). The patients were followed postoperatively at 1, 3, and 6 months, and annually.

RESULTS

Intraoperative hemorrhage at the stapled suture occurred in 13 patients from group 1 and in 6 patients from group 2 (p = 0.03). The degree of postoperative pain was not different between the two groups. During the followup period, radiologic and clinical correction of the rectocele and intussusception was found in 94.6% of the patients, with a recurrence in 1 patient from each group. One patient from group 1 developed stenosis of the anastomosis, which improved with digital dilatations. Six patients from group 1 and none from group 2 (p < 0.05) had granulomas on the staple line at the sites of the reabsorbable reinforcing stitches, which were related to postoperative bleeding and anal discomfort.

CONCLUSIONS

STARR is an effective alternative for treatment of obstructive defecation syndrome, with a low morbidity and a shorter hospital stay. The use of PPH33-03 instead of PPH33-01 decreases the risk of hemorrhagic complications and enables more secure implantation as an outpatient procedure.

Prospective randomised clinical trial of single versus double purse-string stapled mucosectomy in the treatment of prolapsed haemorrhoids

BACKGROUND AND AIMS

Despite the excellent results published on circular stapled mucosectomy (CSM), there is still some concern about the application of PPH-33 in the advanced haemorrhoidal disease, where a major prolapse may lead to insufficient resection and ensuing early recurrence. This study is aimed at comparing the outcomes after single purse-string CSM versus double purse-string CSM.

PATIENTS AND METHODS

A prospective randomised clinical trial of single versus double purse-string CSM for grade III-IV symptomatic haemorrhoids was used. One hundred consecutive patients were randomised to single (group 1, N=50) versus double purse-string CSM (group 2, N=50).

RESULTS

The mean age was 50.7 years, with a predominance of males (63 vs. 37). Haemorrhoids were classified as grade III in 59% and grade IV in 41% of the patients. Mean follow-up was 26 months. Demographic and clinical features showed no differences between the two groups. The size of the resected doughnut was greater in group 2 (4.95 vs. 3.55 cm; p<0.05), as was the distance of the suture from the dentate line (3.56 vs. 3.16 cm; p<0.05). Early postoperative pain was significantly less in group 2 (linear analogue scale from 0 to 10), 2.08 vs. 3.56 (p<0.001). Postoperative haemorrhage was absent or minimal in 79% of patients. Three patients from group 1 reported persistent pain that was resolved within the first few postoperative months. There were two recurrences in group 1.

CONCLUSION

Double purse-string CSM resects a greater doughnut, increases the distance of the staple suture from the dentate line and reduces early postoperative pain in comparison to single purse-string CSM. Larger series are necessary to assert whether recurrence is lower.

Correlation of histology with anorectal function following stapled hemorrhoidectomy

INTRODUCTION

The inadvertent removal of smooth muscle during the use of stapled hemorrhoidectomy had raised concerns about its effects on postoperative anorectal function. We correlated the amount of smooth muscle removed with anorectal function in the early postoperative period.

METHODS

Patients were assessed preoperatively with an Eypasch quality-of-life questionnaire and underwent anorectal manometry and physiology testing. This was followed by a similar examination at three months postoperatively. Patients were operated on by a single surgeon and the excised anorectal mucosa was sent for histologic examination. The amount of smooth muscle excised was expressed semiquantitatively as a percentage of the total tissue removed.

RESULTS

Sixty-eight patients (33 males) were recruited prospectively, with median age of 44 years. Six patients were lost to follow-up. Removal of anal transitional zone did not increase the incidence of incontinence. Both median preoperative and postoperative continence scores were good. Only one patient had incontinence to gas as a result of the operation. Median preoperative and postoperative quality-of-life scores were 114 and 131, respectively, out of a total of 144, the higher postoperative scores showing an improvement. Correlation of quality-of-life scores and mean resting anal pressures with percentage of smooth muscle removed did not show any statistical significance.

CONCLUSIONS

Some smooth muscle will invariably be excised in stapled hemorrhoidectomy but the amount of smooth muscle removed did not significantly affect the continence score, quality of life, or mean anal resting pressure after stapled hemorrhoidectomy. It remains a safe and preferred procedure for the treatment of hemorrhoids.

Pathological audit of stapled haemorhoidopexy

INTRODUCTION

Stapled haemorrhoidopexy is increasingly used for the surgical management of prolapsing haemorrhoids. Accurate placement of the staple line is essential to avoid involvement of the internal anal sphincter (IAS) and the pain sensitive squamous epithelium. The aim of this study was to correlate histology with symptomatic outcome after stapled haemorrhoidopexy.

PATIENTS AND METHODS

A single pathologist reviewed one hundred and six consecutive rectal mucosal specimens. Each specimen was assessed for the presence of columnar, transitional and squamous epithelium as well as involvement of smooth and skeletal muscle. In November 2003 all patients were sent a previously validated postal questionnaire about haemorrhoidal symptoms and a Cleveland Clinic continence scale. Symptomatic outcome was compared between patients who did or did not have squamous epithelium involvement in their pathology specimens and were analysed by Mann-Whitney U-test.

RESULTS

One hundred and six stapled haemorrhoidopexies were performed between June 2001 and September 2003. Eighty-four patients (79%) returned the questionnaire; 19 patients had squamous epithelium present in the pathology specimens. There was no significant difference between symptom or Cleveland Clinic scores in patients with or without squamous epithelium in their pathology specimens. Some specimens (n = 6) were found to have smooth muscle underlying squamous epithelium; this was interpreted as the presence of internal anal sphincter (IAS) within the specimen. There was no significant difference in Cleveland Clinic scores between this group and those without IAS involvement.

CONCLUSION

This study has not demonstrated a long-term difference in symptomatic outcome or continence in patients who have squamous epithelium present in their stapled haemorrhoidopexy specimens.

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.
