Systematic review on the procedure for prolapse and hemorrhoids (stapled hemorrhoidopexy)

A comparative study on efficacy and safety of modified partial stapled hemorrhoidopexy versus conventional hemorrhoidectomy: a prospective randomized controlled trial

PURPOSE

The long-term outcomes and efficacy of partial stapled hemorrhoidopexy (PSH) compared with those of conventional hemorrhoidectomy (CH) are not fully understood. This study aimed to introduce a modified PSH (mPSH) and compare its clinical efficacy and safety with those of CH.

METHODS

A prospective randomized controlled trial was conducted. This study was performed at a single hospital and involved 6 colorectal surgeons. In total, 110 patients were enrolled between July 2019 and September 2020. Patients were randomly assigned to undergo either mPSH group (n=55) or CH group (n=55). The primary outcome was to compare postoperative average pain and postoperative peak pain using visual analog scale score between the 2 groups.

RESULTS

The required duration of analgesia was shorter in the mPSH group than in the CH group, although the difference was not statistically significant (P=0.096). However, the laxative requirement duration (P<0.010), return to work (P<0.010), satisfaction score (P<0.010), and Vaizey score (P=0.014) were significantly better in the mPSH group. The average and peak postoperative pain scores were significantly lower in the mPSH group during the 15 days after surgery (P<0.001). The overall complication rate in both groups was 9.1%, with no significant difference between the groups (P=0.867).

CONCLUSION

The mPSH group demonstrated better improvement in symptoms, lower pain scores, and greater patient early satisfaction after surgery than the CH group. Therefore, this surgical technique appears to be a safe and effective alternative for CH.

The Italian Unitary Society of Colon-Proctology (Società Italiana Unitaria di Colonproctologia) guidelines for the management of acute and chronic hemorrhoidal disease

The aim of these evidence-based guidelines is to present a consensus position from members of the Italian Unitary Society of Colon-Proctology (Società Italiana Unitaria di Colon-Proctologia, SIUCP) on the diagnosis and management of hemorrhoidal disease, with the goal of guiding physicians in the choice of the best treatment option. A panel of experts was charged by the Board of the SIUCP to develop key questions on the main topics related to the management of hemorrhoidal disease and to perform an accurate and comprehensive literature search on each topic, in order to provide evidence-based answers to the questions and to summarize them in statements. All the clinical questions were discussed by the expert panel in multiple rounds through the Delphi approach and, for each statement, a consensus among the experts was reached. The questions were created according to PICO (patients, intervention, comparison, and outcomes) criteria, and the statements were developed adopting the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) methodology. In cases of grade 1 hemorrhoidal prolapse, outpatient procedures including hemorrhoidal laser procedure and sclerotherapy may be considered the preferred surgical options. For grade 2 prolapse, nonexcisional procedures including outpatient treatments, hemorrhoidal artery ligation and mucopexy, laser hemorrhoidoplasty, the Rafaelo procedure, and stapled hemorrhoidopexy may represent the first-line treatment options, whereas excisional surgery may be considered in selected cases. In cases of grades 3 and 4, stapled hemorrhoidopexy and hemorrhoidectomy may represent the most effective procedures, even if, in the expert panel opinion, stapled hemorrhoidopexy represents the gold-standard treatment for grade 3 hemorrhoidal prolapse.

Stapled hemorrhoidopexy for hemorrhoids: A overview of systematic reviews and meta-analysis

Stapled hemorrhoidopexy has been used for years to treat hemorrhoids. Despite numerous systematic reviews and meta-analyses on the topic, inconsistent conclusions have left people uncertain about its effectiveness and raised doubts about the quality of these reviews.In order to provide reliable evidence for clinical practice, it is crucial to conduct an overview to assess the quality of MAs/SRs regarding the efficacy and complications of SH.A comprehensive search was performed across seven databases to identify MAs/SRs on the efficacy and complications of SH from inception to October 2023. The selected MAs/SRs were then assessed using three well-established tools: AMSTAR-2, PRISMA 2020and GRADE. These assessments provide a robust evaluation of the quality and reliability of the included MAs/SRs.We removed overlapping randomized controlled trials (RCTs) and conducted a new meta-analysis of the outcomes. The overview included 23 meta-analyses.In AMSTAR-2, three reviews were deemed moderate quality, nine reviews were classified as low quality, and eleven reviews were evaluated as critically low quality.In PRISMA 2020,certain deficiencies were exhibited, such as abstracts (0/23:0 %),final retrieval date (0/23:0 %), sensitivity analysis (6/23:26.09 %),publication bias assessment (11/23:47.83 %), the quality of evidence (2/23:8.70 %) and so on.In GRADE,twenty-six items were rated as moderate quality (27.96 %),forty-one items were rated as low quality (44.09 %) and twenty-six items were rated as critically low quality (27.96 %).SH has been found to be an effective intervention for reducing postoperative pain, shortening procedure time, and promoting wound healing. The re-analysis indicated that SH can reduce postoperative pain in hemorrhoid patients (odds ratio = 0.28, 95 % confidence interval [0.15,0.55], p = 0.0002; I2 = 74 %, p < 0.00001). But SH is associated with a higher risk of postoperative bleeding and recurrence of prolapse.Given that the reviews included in this overview were rated as low quality, caution should be exercised when interpreting the findings.

Randomized Controlled Trial to Compare Stapled Hemorrhoidopexy Plus Ligation Anopexy With Stapled Hemorrhoidopexy for Managing Grade III and IV Hemorrhoidal Disease

BACKGROUND

Despite the benefits of the stapled hemorrhoidopexy in the short term, management of prolapsing hemorrhoids, the long-term results are still insufficient regarding recurrent prolapse and patient satisfaction. The current study investigates the addition of ligation anopexy to stapled hemorrhoidopexy.

OBJECTIVE

Valuation of adding ligation anopexy to stapled hemorrhoidopexy in improving short-term and long-term results in the treatment of grade III and IV hemorrhoids.

DATA SOURCES

Between January 2018 and January 2020, we recruited 124 patients with grade III and IV hemorrhoids at Alexandria Main University Hospital.

STUDY SELECTION

Randomized controlled trial.

INTERVENTIONS

One hundred twenty-four patients were blindly randomly assigned to 2 equal groups: stapled hemorrhoidopexy (group I) and stapled hemorrhoidopexy plus ligation anopexy (group II).

MAIN OUTCOME MEASURES

Recurrence of hemorrhoids and patient satisfaction after a follow-up period of at least 2 years.

RESULTS

The average operating time was noticeably less in the stapled hemorrhoidopexy group. Postoperative pain, analgesia requirement, hemorrhoid symptoms score, return to work, complications rate, and quality of life 1 month after surgery were similar between groups. Following a mean follow-up of 36 months (interval, 24-47), in group I, 10 patients (16%) reported recurrent external swelling and/or prolapse compared to 3 patients (5%) in group II ( p  = 0.0368). Five patients in group I required redo surgery, whereas no patients required redo surgery in group II. Long-term patient satisfaction was significantly better in group II.

LIMITATIONS

It was a single-center experience, so longer follow-up was needed.

CONCLUSIONS

Stapled hemorrhoidopexy and stapled hemorrhoidopexy plus ligation anopexy were similar in short-term results with regard to complications rate, hemorrhoids symptoms score, return to work, and quality of life. Long-term results were significantly better with regard to recurrence of external swelling and/or prolapse and patient satisfaction after stapled hemorrhoidopexy plus ligation anopexy.

The importance of compression time in stapled hemorrhoidopexy: is patience a virtue?

PURPOSE

The aim of this study was to evaluate whether longer compression time before firing the stapler reduced the postoperative complications related to staple line formation in stapled hemorrhoidopexy.

METHODS

This retrospective case-control study was conducted at a colorectal-anal specialty hospital. Consecutive patients with grades III and IV hemorrhoids who underwent stapled hemorrhoidopexy between January 2016 and November 2019 were included. According to the compression time, patients were assigned to the long compression time group (2 minutes) or the typical compression time group (30 seconds). The primary outcome measure was incidence of staple line complications such as dehiscence, bleeding, and stenosis.

RESULTS

A total of 348 patients treated with stapled hemorrhoidopexy were evaluated. Seventy-three and 275 patients were included in the long compression time group and the typical compression time group, respectively. No significant differences were observed in patient characteristics between the groups. However, additional procedures were performed more frequently in the typical compression time group (78.1% vs. 92.0%, P=0.001). Bleeding occurred more frequently in the typical compression time group (1.4% vs. 8.4%, P=0.030). The rates of dehiscence and stenosis were not significantly different between the groups. Fecal urgency developed more frequently in the typical compression time group (0% vs. 5.1%, P=0.040). In logistic regression analysis, typical compression time (30 seconds) was the only risk factor for bleeding (odds ratio, 8.496; P=0.040).

CONCLUSION

Longer compression time was associated with a decreased incidence of postoperative bleeding after stapled hemorrhoidopexy.

Accelerated wound healing after topical application of hyaluronic acid cotton to hemorrhoidectomy wounds in a rat model

Purpose

Anal wounds following hemorrhoidectomy can lead to severe pain and postoperative bleeding, impacting patient recovery and quality of life. Hyaluronic acid (HA) stimulates tissue regeneration and wound healing by accelerating cell migration and proliferation. This study aimed to investigate the differences in wound healing rate and completeness of recovery of perianal wounds topically treated with HA-soaked cotton in a murine model.

Methods

Forty-eight 8-week-old Sprague-Dawley rats with perianal wounds created using a biopsy punch were divided into 2 groups: simple dressing with gauze (control) and topical HA-soaked cotton. A single application of HA-soaked cotton was administered after surgery. Wound healing rate and completeness of recovery were evaluated by measuring the healed area and conducting histological analyses.

Results

The HA-cotton group exhibited a shorter complete wound healing duration compared to the control group (13.9 days vs. 16.4 days, P = 0.031). Differences in wound healing area between the 2 groups were greatest on postoperative day 2 (51.6% vs. 28.8%, P < 0.001). The HA-cotton group exhibited fewer cases of granulation tissue (2 vs. 5) or redness (0 vs. 3) upon complete wound healing. Histologically, the HA-cotton group showed accelerated reepithelialization, rapid shift to lymphocyte-dominant inflammation, enhanced fibroblast proliferation, and increased collagen deposition compared to the control group.

Conclusion

Herein, topical application of HA-soaked cotton on perianal wounds in rats resulted in accelerated wound healing, particularly in the initial stages, and improved completeness of recovery, underscoring the potential of the topical application of HA-soaked cotton on hemorrhoidectomy wounds in human patients to improve wound healing.

The comparison of an accessible C-shaped partial stapled hemorrhoidopexy (C-PSH) versus circular stapled hemorrhoidopexy (CSH) in patients with grade IV hemorrhoids: a retrospective cohort study

OBJECTIVES

The objectives of this study were to present an accessible C-shaped partial stapled hemorrhoidopexy (C-PSH) in the treatment of grade IV hemorrhoids and to assess long-term outcomes of this technique compared with circular stapled hemorrhoidopexy (CSH).

METHODS

Conventional CSH kits combined with an intestinal spatula were used for performing C-PSH. A total of 256 patients with grade IV hemorrhoids referred to Hangzhou Third People's Hospital between January 2016 and June 2017 were obtained: 122 (47.7%) with C-PSH, and 134 (52.3%) with CSH. After propensity score matching, 222 patients (111 in C-PSH group and 111 in CSH group) were ultimately analyzed. The primary outcome was the five-year recurrence rate of hemorrhoids. Secondary outcomes included intraoperative outcomes, postoperative outcomes and complications.

RESULTS

The operative time in the C-PSH group was slightly longer than that in the CSH group (p < 0.01). The vertical length of rectal mucosa specimen in the C-PSH group was shorter than that in the CSH group (p < 0.01). Compared with the CSH group, fecal urgency incidence and numeric rating scale (NRS) score at first defecation were lower in the C-PSH group (p < 0.05). Major complication rate in the CSH group was higher than that in the C-PSH group (p = 0.03). Five-year recurrence rate between the C-PSH group and CSH group was comparable (p > 0.05). Multivariate Cox regression analysis revealed that constipation was an independent prognostic factor for hemorrhoidal recurrence.

CONCLUSIONS

The accessible C-PSH seems to be a safe and effective technique in managing grade IV hemorrhoids. It has advantages in alleviating postoperative pain at first defecation, fecal urgency and major complications compared with CSH. It could be an alternative technique in the treatment of grade IV hemorrhoids.

Comparison of the efficacy and safety of different surgical procedures for patients with hemorrhoids: a network meta-analysis

PURPOSE

This study used a network meta-analysis to evaluate the efficacy and safety of different surgical approaches in patients with hemorrhoids.

METHODS

PubMed, Embase, Web of science, and Cochrane Library were searched for randomized controlled trials on patients with hemorrhoids treated by different surgical procedures. The search was conducted until January 15, 2023. Two investigators independently screened the resulting literature, extracted information, evaluated the risk of bias of the included studies, and performed a network meta-analysis.

RESULT

A total of 23 randomized controlled studies were included and involved 3573 patients and 10 interventions, namely L (Ligasure), M-M (Milligan-Morgan), F (Ferguson), H (Harmonic), OH (open Harmonic), CH (closed Harmonic), PPH (procedure for prolapse and hemorrhoids), TST (tissue selecting technique), T-S (TST STARE+; tissue selection therapy stapled transanal rectal resection plus), and STARR (stapled transanal rectal resection). Network meta-analysis results showed that L has the shortest mean operating time and STARR has the longest mean operating time, F and H have the longest length of hospitalization and T-S has the shortest length of hospitalization, PPH has the most intraoperative blood loss and L has the least intraoperative blood loss, TST has the shortest time to first defecation and M-M has the longest time to first defecation, STARR had the least recurrence and PPH had the most recurrence, PPH had the least anal stenosis and L had the most anal stenosis, and F had the least postoperative pain after 24 h and PPH had the most postoperative pain after 24 h.

CONCLUSION

Current evidence suggests that L is best at reducing mean operative time and intraoperative bleeding, T-S is best at reducing mean length of stay, TST has the shortest time to first defecation, STARR is best at reducing recurrence rates, PPH is best at reducing postoperative anal stricture, and F is best at reducing postoperative pain after 24 h.

[Hemorroids Therapy: a Tailored Approch]

One of the most common reasons to consult a coloproctologist is symptomatic haemorrhoids. Typical signs and symptoms as well as a specialised examination, including proctoscopy, are essential for the correct diagnosis. The vast majority of patients can be treated conservatively with excellent results in terms of quality of life. Sclerotherapy provides good control of symptoms at any stage of haemorrhoidal disease. If conservative treatment fails, there are various surgical options. A tailored approach is mandatory. Besides well-known procedures such as Fergusson, Milligan-Morgan procedure or haemorrhoidopexy (Longo) there are less invasive options such as HAL-RAR, IRT, LT and RFA. Postoperative bleeding, pain and faecal incontinence are rare complications after surgery.

Electroacupuncture at Baliao point alleviates post-operative pain and anal distension after procedure for prolapse and hemorrhoids (stapled hemorrhoidopexy): a prospective randomized clinical trial

PURPOSE

The purpose of this study was to explore the effect of electroacupuncture (EA) at Baliao point on short-term complications, such as anal pain and swelling, after procedure for prolapse and hemorrhoids (PPH) in patients with mixed hemorrhoids.

METHODS

A total of 124 eligible patients undergoing PPH surgery were included in this study and randomly divided into a control group (n = 67) and an EA group (n = 57), with patients in the control group receiving only PPH surgery and patients in the EA group receiving PPH surgery and EA at Baliao point.

RESULTS

The visual analogue scale (VAS) scores of EA group at 8, 24, 48, and 72 h after operation were significantly lower than those of control group. The anal distension scores at 8, 48, and 72 h after operation were also significantly lower than those of control group. The number of postoperative analgesic drug administration per patient was also significantly lower in the EA group. The incidence of urinary retention and tenesmus in EA group was significantly lower than that in control group within the first day after surgery.

CONCLUSION

EA treatment at the Baliao point can alleviate short-term anal pain and anal swelling after the procedure for prolapse and hemorrhoids, reduce the incidence of urinary retention, and decrease the use of postoperative analgesic drugs.

Analgesic effect of subcutaneous injection of different concentrations of methylene blue after hemorrhoidectomy: A retrospective study

Objective

Subcutaneous injection of methylene blue around the anus may help reduce postoperative pain. However, the concentration of methylene blue is still controversial. Therefore, Our study aims to investigate the efficacy and safety of different methylene blue injected concentrations subcutaneously in pain treatment after hemorrhoidectomy.

Methods

A total of 180 consecutive patients with grade III or IV hemorrhoids from March 2020 to December 2021 were reviewed. All patients underwent hemorrhoidectomy under spinal anesthesia and were divided into three groups. Group A received subcutaneous injection of 0.1% methylene blue after hemorrhoidectomy, group B received subcutaneous injection of 0.2% methylene blue, and Group C did not received subcutaneous injection of methylene blue. The primary outcome measures were the visual analog scale (VAS) pain score on postoperative days 1, 2, 3, 7, 14, and total analgesic consumption within 14 days. Secondary outcomes were complications after hemorrhoidectomy, including acute urinary retention, secondary bleeding, perianal incision edema, and perianal skin infection, and the Wexner scores used to assess the level of anal incontinence at one and three months after surgery.

Results

There was no significant difference among three groups in sex, age, course of the disease, hemorrhoid grade and the number of incisions, and there was no significant difference in the volume of methylene blue injected between group A and group B. The VAS pain score and total analgesics consumption within 14 days in group A and group B were significantly lower than those in group C, but the differences between group A and group B were not statistically significant. The Wexner scores of group B were significantly higher than those of group A and group C one month after the operation, but the differences between group A and group C were not statistically significant. In addition, the Wexner score among three groups decreased to zero at three months after operation. There was no significant difference in the incidence of other complications among three groups.

Conclusion

The perianal injection of 0.1% methylene blue and 0.2% methylene blue have a similar analgesic effect in pain treatment after hemorrhoidectomy, but 0.1% methylene blue has higher safety.

Tissue-selecting-technique mega-window stapler combined with anal canal epithelial preservation operation in prolapsed hemorrhoids

OBJECTIVE

This study aimed to compare the efficiency of these two combined surgeries [prolapse and hemorrhoids (PPH) combined with the external hemorrhoidectomy and inferior internal hemorrhoid ligation; tissue selecting technique with mega-window stapler (TST-MS) combined with anal canal epithelial preservation operation].

METHODS

This is a single-center, evaluator-blinded randomized controlled trial (RCT). A total of 204 participants were randomly divided into the two groups. The anal function, reoccurrence, intraoperative variables, and operative complications were assessed. The measurement data were compared by paired t test and rank sum test. Chi-squared or Fisher's exact test was used for count data and rank sum test for ranked data. To assess differences within each group in different time points, the repeated-measures analysis of variance was conducted.

RESULTS

TST-MS combined with anal canal epithelial preservation operation had lower Wexner score of anal incontinence (Z = 3.062, P = 0.002), higher patients' satisfaction degree (t = 7.32, P < 0.001), less residual skin tags (χ² = 18.141, P < 0.001), longer operative time (Z = -2.281, P = 0.023), and bigger volume of excised rectal mucosa (t = 2.35, P = 0.020). There was no significant difference between the two groups in the anal canal circumference, recurrence, intraoperative blood loss, weight of excised rectal mucosa, anal pain, bleeding, urinary retention, anal edge edema, and anatomical anal stenosis (all P > 0.05).

CONCLUSIONS

TST-MS combined with anal canal epithelial preservation operation showed better clinical efficiency in the treatment of prolapsed hemorrhoids.

Long-term outcomes of high-volume stapled hemorroidopexy to treat symptomatic hemorrhoidal disease

PURPOSE

The study aimed to assess the long-term results of the stapled hemorrhoidopexy (SH) using high-volume devices equipped with innovative technology, evaluating recurrence rate, complications rate, and patients' satisfaction.

METHODS

All the patients who underwent SH using high-volume devices (TST Starr plus, Touchstone International Medical Science Corp., Ltd.) for II to IV symptomatic hemorrhoidal disease from November 2012 to December 2014 were enrolled. Between December 2019 and January 2020, all of them were phone called to come to undergo a proctological reevaluation and asked to fill some questionnaires about hemorrhoidal prolapse recurrence, symptoms recurrence, and surgery satisfaction.

RESULTS

Fifty-nine patients with a mean age of 47 years completely answered the questionnaires. Twenty-two of them accepted to come to undergo a proctological reevaluation while 27 preferred to answer only by phone due to their referred wellbeing. The median follow-up was 70.5 months (range, 60-84 months). The recurrence rate was 5.1% with a mean satisfaction level after surgery was 9.1 (range, 0-10) and 84.7% of patients whose satisfaction scored ≥8. The mean value of Cleveland Global Quality of Life assessment was 0.79 (range, 0.71-0.93). There were no cases of new onset of impaired anal continence after surgery.

CONCLUSION

The new generation high-volume devices to perform SH resulted to be safe and effective for II to IV degree hemorrhoidal prolapse leading to a lower long-term recurrence rate with an evident reduction of postoperative complications in comparison with the low-volume SH.

The effects of laser procedure in symptomatic patients with haemorrhoids: A systematic review

Purpose

Haemorrhoids are normal structures in the human body, only seen as pathological when symptomatic. Nowadays, new techniques have surfaced using a diode laser which, after locating the target arteries, blocks the blood flow while hitting and shrinking the local mucosa/submucosa at a depth of 4 mm. Our work aimed to give a broad view over this new technique and its consequences in the post-operative follow-up with a systematic review.

Methods

EMBASE and MEDLINE databases were consulted, retrieving clinical trials, which mentioned the use of 980 nm diode laser on the treatment of haemorrhoids.

Results

Ten clinical trials analyzing the post-operative effects of laser haemorrhoidectomy were selected, including 2 randomized controlled clinical trials and 1 controlled clinical trial. The overall quality of the trials was low, indicating a high risk of bias.

Conclusion

The laser haemorrhoidectomy procedure revealed a high therapeutic potential, considering the reduced number of postoperative complaints (bleeding/pain), the high symptom resolution and the reduced recurrence, albeit the high heterogeneity between the studies in terms of reported results. Future investigations with higher quality and controlled double-blinded studies obtaining better-categorized results should be conducted in order to better evaluate this procedure and compare it to the current paradigm.

Top 100 most-cited articles on hemorrhoids: A bibliometric analysis and visualized study

Background

Hemorrhoids have a significant incidence in people and are becoming a common public health problem. This study provides a bibliometric and visualized analysis of the most influential literature in the field. The aim is to reveal trends in the field of hemorrhoids and to provide a reference for researchers.

Methods

The 100 most frequently cited studies in the field of hemorrhoids were collected from the Web of Science(WOS), and were analyzed in terms of the annual publication, types of literature, countries, institutions, authors, journals, and keywords. During the study, we used a combination of VosViewer, Carrot2, Microsoft Excel, and Tableau tools to better present the visual information.

Results

A total of 4,481 articles were retrieved, of which 3,592 were of the Article and Review types, among which we selected the 100 most frequently cited. A large amount of highly cited literature on hemorrhoid surgery emerged from 1990 to 2010, and the interest of researchers in hemorrhoid surgery seems to have waned after 2010. The sources of highly cited literature in the field of hemorrhoids are predominantly Western, with the United States. and the United Kingdom accounting for almost half of the publications worldwide. However, countries with higher prevalence populations do not have significant research on hemorrhoids. St. Mark's Hospital has published the largest number of influential articles in the field of hemorrhoid disease. Kamm MA and Phillips RKS are the most authoritative authors in the field. Diseases of the Colon & Rectum and the British Journal of Surgery are the most influential journals in this field. The highly cited literature covers a wide range of disciplines, with Thomson's classic “The nature of hemorrhoids” receiving the most attention among the studies focusing on hemorrhoids. Keyword and clustering analysis revealed that The most famous focus in the field of hemorrhoid research is the evolution of stapled hemorrhoidectomy (SH) and Milligan-morgan hemorrhoidectomy (MMH).

Conclusions

This study is the first to explore developments in the field of hemorrhoids, and it helps surgeons quickly understand global trends in the field of hemorrhoids. In recent years, the development of hemorrhoids seems to have hit a bottleneck, with scholarly interest in the field of waning, especially in surgery Procedures. The theory of inferior anal cushion migration has proven to be the most influential theory in the field, but after studies based on SH and MMH, more high-quality evidence is needed to continue advancing the field of hemorrhoids. The results of this study are intended to add to the attention and interest of scholars in this area and provide a reference for further research.

Clinical study of use of large C suture in procedure for prolapse and hemorrhoids for treatment of mixed hemorrhoids

OBJECTIVE

To investigate the clinical use of a large C suture in the procedure for prolapse and hemorrhoids (PPH) for treatment of mixed hemorrhoids.

METHODS

Patients with mixed hemorrhoids (grade III or IV) who underwent treatment with a large C suture during PPH in the Affiliated Hospital (Group) of Putian University from 1 April 2018 to 31 March 2019 were enrolled in this retrospective study. The incidences of anastomotic stenosis and anastomotic hemorrhage after the operation were observed.

RESULTS

The study population comprised 126 patients (46 men and 80 women) ranging in age from 30 to 78 years (mean, 46.1 ± 2.5 years). Of these patients, 60 had circular mixed hemorrhoids, 36 had grade III circular internal hemorrhoids, and 30 had grade IV circular internal hemorrhoids. The onset time among all patients ranged from 0.5 to 25 years. All patients underwent 6 months of postoperative follow-up. None of the patients with mixed hemorrhoids developed anastomotic stenosis, although two patients developed secondary anastomotic bleeding.

CONCLUSION

Placement of a large C suture during PPH is a reliable technique for treatment of mixed hemorrhoids. It is simple, effective, and applicable and can be helpful for a large number of patients in primary hospitals.

Modified procedure for prolapse and hemorrhoids: Lower recurrence, higher satisfaction

BACKGROUND

Hemorrhoidal prolapse is a common benign disease with a high incidence. The treatment procedure for prolapse and hemorrhoids (PPH) remains an operative method used for internal hemorrhoid prolapse. Although it is related to less pos-operative pain, faster recovery and shorter hospital stays, the postoperative recurrence rate is higher than that of the Milligan-Morgan hemorrhoidectomy (MMH). We have considered that recurrence could be due to shortage of the pulling-up effect. This issue may be overcome by using lower purse-string sutures [modified-PPH (M-PPH)].

AIM

To compare the therapeutic effects and the patients’ satisfaction after M-PPH, PPH and MMH.

METHODS

This retrospective cohort study included 1163 patients (M-PPH, 461; original PPH, 321; MMH, 381) with severe hemorrhoids (stage III/IV) who were admitted to The 2^nd Affiliated Hospital and Yuying Children’s Hospital of Wenzhou Medical University from 2012 to 2014. Early postoperative complications, efficacy, postoperative anal dysfunction and patient satisfaction were compared among the three groups. Established criteria were used to assess short- and long-term postoperative complications. A visual analog scale was used to evaluate postoperative pain. Follow-up was conducted 5 years postoperatively.

RESULT

Length of hospital stay and operating time were significantly longer in the MMH group (8.05 ± 2.50 d, 19.98 ± 4.21 min; P < 0.0001) than in other groups. The incidence of postoperative anastomotic bleeding was significantly lower after M-PPH than after PPH or MMH (1.9%, 5.1% and 3.7%; n = 9, 16 and 14; respectively). There was a significantly higher rate of sensation of rectal tenesmus after M-PPH than after MMH or PPH (15%, 8% and 10%; n = 69, 30 and 32; respectively). There was a significantly lower rate of recurrence after M-PPH than after PPH (8.7% and 18.8%, n = 40 and 61; P < 0.0001). The incidence of postoperative anal incontinence differed significantly only between the MMH and M-PPH groups (1.3% and 4.3%, n = 5 and 20; P = 0.04). Patient satisfaction was significantly greater after M-PPH than after other surgeries.

CONCLUSION

M-PPH has many advantages for severe hemorrhoids (Goligher stage III/IV), with a low rate of anastomotic bleeding and recurrence and a very high rate of patient satisfaction.

Long-Term Functional Outcome After Stapled and Excisional Hemorrhoidectomy

Stapled hemorrhoidectomy (SH) as described by Longo is a recently added option for hemorrhoid surgery. Interest in SH has been principally driven by the fact that conventional excision hemorrhoidectomy (EH) has been an extremely painful procedure because it involves excision of hemorrhoidal tissue along the extremely sensitive anoderm. SH, on the other hand, has been shown to be associated with decreased postoperative pain because it does not involve the sensate anal mucosa below the dentate line. To date there have been many randomized controlled studies comparing circular SH with traditional excision techniques. Despite proven early postoperative advantages for SH, the long-term benefits and effect on patient quality of life (QOL) compared with EH still remain to be debated. This study aimed to evaluate long-term patient outcomes via a validated health-related QOL survey. QOL measures were satisfactory in both groups across all subscales of physical health summary measures and mental health summary measures. This coincided with Wexner continence scores, which were also satisfactory, with a median of 0 in both groups. QOL, continence scores, and long-term symptom follow-up are similar in patients who undergo SH or EH.

A new technique of doppler dearterialization for hemorrhoidal disease: arterial detection ligation (ADL)

PURPOSE

We describe the arterial detection ligation (ADL) technique, designed to find arteries at time-appropriate depth for ligating, and report our preliminary results of using this technique to treat patients with the hemorrhoidal disease (HD).

METHODS

The subjects of this retrospective analysis were patients with symptomatic grades 2 or 3 HD. We analyzed the clinical characteristics, postoperative complications, recurrence, and patient satisfaction of the patients treated with ADL.

RESULTS

A total of 75 patients were included in the study (male/female ratio 1.88; mean age 48 ± 19 years; mean BMI 24 ± 3 kg/m²). Thirty-nine patients (52%) did not require hospitalization and were discharged from the day clinic approximately 4 h postoperatively. Four patients (5.3%) suffered tenesmus for about 1 week postoperatively and two (2.7%) suffered temporary rectal bleeding. The mean VAS scores 1 day postoperatively, then at 1 week, 1 month and 1 year were 2.9, 1.5, 0.4, and 0, respectively. At the 1-month follow-up, there was no sign of recurrence and the satisfaction rate was 78.6% (n = 59). At the 1-year follow-up, three patients (4%) had a recurrence and the satisfaction rate was 86.7% (n = 65).

CONCLUSION

Based on our preliminary findings, ADL is an effective technique for treating HD, generally as an outpatient procedure, without serious morbidity. We anticipate that the incidence of tenesmus, which is encountered frequently after other dearterialization methods, will be lower after the ADL technique, which avoids both mass ligation of hemorrhoidal arteries deeper than 12 mm and running a long mucopexy suture line.

European Society of ColoProctology: guideline for haemorrhoidal disease

AIM

The goal of this European Society of ColoProctology project was to establish a multidisciplinary, international guideline for haemorrhoidal disease (HD) and to provide guidance on the most effective (surgical) treatment for patients with HD.

METHODS

The development process consisted of six phases. In phase one we defined the scope of the guideline. The patient population included patients with all stages of haemorrhoids. The target group for the guideline was all practitioners treating patients with haemorrhoids and, in addition, healthcare workers and patients who desired information regarding the treatment management of HD. The guideline needed to address both the diagnosis of and the therapeutic modalities for HD. Phase two consisted of the compilation of the guideline development group (GDG). All clinical members needed to have affinity with the diagnosis and treatment of haemorrhoids. Further, attention was paid to the geographical distribution of the clinicians. Each GDG member identified at least one patient in their country who could read English to comment on the draft guideline. In phase three review questions were formulated, using a reversed process, starting with possible recommendations based on the GDG's knowledge. In phase four a literature search was performed in MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews. The search was focused on existing systematic reviews addressing each review question, supplemented by other studies published after the time frame covered by the systematic reviews. In phase five data of the included papers were extracted by the surgical resident (RT) and checked by the methodologist (JK) and the GDG. If needed, meta-analysis of the systematic reviews was updated by the surgical resident and the methodologist using Review Manager. During phase six the GDG members decided what recommendations could be made based on the evidence found in the literature using GRADE.

RESULTS

There were six sections: (i) symptoms, diagnosis and classification; (ii) basic treatment; (iii) outpatient procedures; (iv) surgical interventions; (v) special situations; (vi) other surgical techniques. Thirty-four recommendations were formulated.

CONCLUSION

This international, multidisciplinary guideline provides an up to date and evidence based summary of the current knowledge of the management of HD and may serve as a useful guide for patients and clinicians.

Still a Case of "No Pain, No Gain"? An Updated and Critical Review of the Pathogenesis, Diagnosis, and Management Options for Hemorrhoids in 2020

The treatment of haemorrhoids remains challenging: multiple treatment options supported by heterogeneous evidence are available, but patients rightly demand a tailored approach. Evidence for newer surgical techniques that promise to be less painful has been conflicting. We review the current evidence for management options in patients who present with varying haemorrhoidal grades. A review of the English literature was performed utilizing MEDLINE/PubMed, Embase, and Cochrane databases (31 May 2019). The search terms (haemorrhoid OR haemorrhoid OR haemorrhoids OR haemorrhoids OR "Hemorrhoid"[Mesh]) were used. First- and second-degree haemorrhoids continue to be managed conservatively. The easily repeatable and cost-efficient rubber band ligation is the preferred method to address minor haemorrhoids; long-term outcomes following injection sclerotherapy remain poor. Conventional haemorrhoidectomies (Ferguson/Milligan-Morgan/Ligasure haemorrhoidectomy) still have their role in third- and fourth-degree haemorrhoids, being associated with lowest recurrence; nevertheless, posthaemorrhoidectomy pain is problematic. Stapled haemorrhoidopexy allows quicker recovery, albeit at the costs of higher recurrence rates and potentially serious complications. Transanal Haemorrhoidal Dearterialization has been promoted as nonexcisional and less invasive, but the recent HubBLe trial has questioned its overall place in haemorrhoid management. Novel "walk-in-walk-out" techniques such as radiofrequency ablations or laser treatments will need further evaluation to define their role in modern-day haemorrhoid management. There are numerous treatment options for haemorrhoids, each with their own evidence-base. Newer techniques promise to be less painful, but recurrence rates remain an issue. The balance continues to be sought between long-term efficacy, minimisation of postoperative pain, and preservation of anorectal function.

Mucopexy-Recto Anal Lifting (MuRAL) in managing obstructed defecation syndrome associated with prolapsed hemorrhoids and rectocele: preliminary results

Purpose

Treatment of rectocele associated with prolapsed hemorrhoids is a debated topic. Transanal stapling achieved good midterm results in patients with symptoms of obstructed defecation, nevertheless a number of severe complications have been reported. The aim of this study was to evaluate the safety and efficacy of a new endorectal manual technique in patients with obstructed defecation due to the combination of muco-hemorrhoidal prolapse and rectocele.

Methods

Patients enrolled after preoperative obstructed defecation syndrome (ODS) score, defecography and anoscopy were submitted to the novel Mucopexy-Recto Anal Lifting (MuRAL) combined with a modified Block procedure, and followed up by independent observers with digital exploration 3 weeks postoperatively, and digital exploration plus anoscopy at 3, 6, and 12 months. Operative time, hospital stay, numerating rating scale (NRS), ODS, satisfaction scores, and recurrence rate were recorded.

Results

Mean operative time was 35.7 minutes. Fifty-six patients completed 1-year follow-up: 7.1% had acute urinary retention, NRS score was < 3 from the third postoperative day, mean time of daily activity resumption was 12 days, none had persistent fecal urgency, 82% declared excellent/good satisfaction score, significant improvement of 6- and 12-month ODS score, no recurrence of rectocele, and 7.1% recurrence of prolapsed hemorrhoids were observed.

Conclusion

MuRAL associated with modified Block technique gave no severe complications and resulted in a safe and effective approach to symptomatic rectocele associated with muco-rectal prolapse. Further randomized studies, larger series, and longer follow-up are needed.

Evacuatory Dysfunction after Stapled Hemorrhoidopexy: A Case Report of Rectal Pocket Syndrome

A 60 year-old male was referred to the authors' hospital with a persistent urge to defecate. The patient had undergone stapled hemorrhoidopexy (SH) for the treatment of prolapsed hemorrhoids approximately 10 years earlier. He started to have difficulty with defecation and a false sense of urgency shortly after the surgery. Computed tomography showed a diverticulum-like fistula along the circumference of the rectum. Colonoscopy revealed communication between the diverticular cavity and the rectal lumen. The cavity contained a thumbnail-sized fecalith. When the fecalith was removed, the patient's urge to defecate dissipated. The patient was diagnosed with rectal pocket syndrome secondary to SH. The lower rectum was transected, and the remaining rectum and the anal canal were anastomosed by manual suture. Temporary ileostomy with double orifices was performed. The ileostomy was closed 3 months later. The patient experienced no subsequent difficulty with defecation or urgency.

Management of haemorrhoids: protocol of an umbrella review of systematic reviews and meta-analyses

INTRODUCTION

The prevalence of haemorrhoidal diseases was high in general population, and many treatments are proposed for the management of haemorrhoids. The treatments include conservative and surgical interventions; the credibility and strength of current evidence of their effectiveness are not comprehensively evaluated. We aim to evaluate the credibility of systematic reviews and meta-analyses that assess the effectiveness of the treatments for haemorrhoidal diseases through an umbrella review.

METHODS AND ANALYSIS

We will search Ovid Medline, Embase, Cochrane library and Web of Science from inception to March 2020 without any language restriction. We will include meta-analyses that examine the effectiveness of treatments in the management of haemorrhoids. Two reviewers will independently screen the titles and abstracts of retrieved articles, and they will extract data from the included meta-analyses. For each meta-analysis, we will estimate the effect size of a treatment through the random-effect model and the fixed-effect model, and we will evaluate between-study heterogeneity (Cochrane's Q and I2 statistics) and small-study effect (Egger's test); we will also estimate the evidence of excess significance bias. Evidence of each treatment will be graded according to prespecified criteria. Methodological quality of each meta-analysis will be evaluated by using Assessment of Multiple Systematic Reviews 2. The corrected cover area method will be used to assess the impact of overlap in reviews on the findings of the umbrella review.

ETHICS AND DISSEMINATION

We will present the results of the umbrella review at conferences and publish the final report in a peer-reviewed journal. The umbrella review does not require ethical approval.

Comparison of the short-term outcomes of using DST and PPH staplers in the treatment of grade III and IV hemorrhoids

Stapled hemorrhoidopexy has a few advantages such as less postoperative pain and faster recovery compared with conventional hemorrhoidectomy. There are two major devices used for stapled hemorrhoidopexy, PPH stapler (Ethicon EndoSurgery) and DST stapler (Covidien). This study was conducted to investigate the postoperative outcomes among patients with grade III and IV hemorrhoids who underwent hemorrhoidopexy with either of these two devices. A total of 242 consecutive patients underwent stapled hemorrhoidopexy with either PPH stapler (110 patients) or DST stapler (132 patients) at a single center in 2017. We performed a retrospective case–control study to compare the short-term postoperative outcomes and the complications between these two groups. After matching the cases in terms of age, gender, and the grade of hemorrhoids, there were 100 patients in each group (PPH versus DST). There were no significant differences in the postoperative visual analog scale (VAS) score and analgesic usage. Among complications, the incidence of anorectal stricture was significantly higher in the DST group (p = 0.02). Evaluation of the mucosal specimen showed that the total surface area, the muscle/mucosa ratio and the surface area of the muscle were also significantly higher in the DST group (p = 0.03). Further analysis of the DST group demonstrated that patients with anorectal stricture after surgery are younger than patients without anorectal stricture, and higher muscle/mucosa ratio (p = 0.03) and a higher surface area of the muscle (p = 0.03) also measured in the surgical specimen. The two devices provide similar outcomes of postoperative recovery. Patients who underwent DST stapled hemorrhoidopexy had a higher incidence rate of stricture, larger area of muscle excision, and higher muscle/mucosa ratio in the surgical specimen. Further investigation is warranted for a better understanding of the correlation between muscle excision and anorectal stricture.

Consensus statement of the Italian society of colorectal surgery (SICCR): management and treatment of hemorrhoidal disease

Hemorrhoidal disease (HD) is the most common proctological disease in the Western countries. However, its real prevalence is underestimated due to the frequent self-medication.The aim of this consensus statement is to provide evidence-based data to allow an individualized and appropriate management and treatment of HD. The strategy used to search for evidence was based on application of electronic sources such as MEDLINE, PubMed, Cochrane Review Library, CINAHL, and EMBASE.These guidelines are inclusive and not prescriptive.The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by American College of Chest Physicians. The recommendations were graded A, B, and C.

Long-Term Results After Stapled Hemorrhoidopexy: A 15-Year Follow-Up

BACKGROUND

The stapled hemorrhoidopexy is reported to have a low recurrence while treating the major hemorrhoidal symptoms of bleeding and prolapse. The aim of this study is to obtain long-term results on the outcome of the stapled hemorrhoidopexy.

METHODS

All patients with a hemorrhoidal disease grade III, who underwent stapled hemorrhoidopexy from May 1999-December 2003, were included. Data collection was based on a standardized telephone interview. In the questionnaire, we recorded information regarding the postoperative recurrence and severity of hemorrhoidal symptoms (defined as bleeding, prolapse, burning, itching and moisture), further hemorrhoidal treatments and functional results (incontinence, fecal urgency and outlet obstruction) as well as patients' satisfaction.

RESULTS

Of the 257 patients, who underwent stapled hemorrhoidopexy, follow-up data were available in 140 patients. In 47.4% of the patients, a recurrence of at least one hemorrhoidal symptom was registered, whereas this recurrence was observed in 47.3% of these patients more than 10 years postoperatively. A surgical re-intervention was necessary in 15.2%. We found a postoperative new incontinence in 15.5%, a fecal urgency in 28.0% and an outlet obstruction in 9.4%. Of all patients, 62.3% were "very satisfied" with the operation.

CONCLUSIONS

The results of the study revealed a relatively high recurrence of hemorrhoidal symptoms after a mean follow-up of 15 years with a high recurrence rate more than 10 years postoperatively. In consideration of not negligible risk of incontinence, fecal urgency and outlet obstruction, the indication for a stapled hemorrhoidopexy should be made well considered. However, patients' satisfaction is very high.

Integrated Treatment With Stapled Haemorrhoidopexy and Proctonorm® of Haemorrhoidal Disease

BACKGROUND/AIM

This retrospective study was performed in patients undergoing Stapled Haemorrhoidopexy (SH) who were post-operatively treated with Proctonorm® with the aim of assessing its effect on early and late haemorrhoidal-related symptoms.

PATIENTS AND METHODS

Forty-six males and 54 females received Proctonorm® (one tablet twice daily for 14 days) and Ketoprofene R (200 mg, one tablet twice daily, as requested).

RESULTS

"Early Complication Score" (0-12) two days after surgery was 2.02±1.03; pain VAS (Visual Analogue Scale) (0-10) was 1.21±0.89, and the number of anti-inflammatory tablets was 4.24±1.06. At 40-day post-operative assessment, seven patients had post-operative complications with "Late Complication Score" (0-20) of 0.34±0.68. At six-month follow-up, a high index of patient satisfaction (VAS=9.39±0.24) was self-reported with 75% reduction in CSS (Constipation Scoring System) (1.95±2.58) compared to preoperative scores; "Late Complication Score" was 0.

CONCLUSION

The specific target activity of Proctonorm® at the microcircular level may be effective in patients undergoing SH in order to reduce the inflammatory response of residual haemorrhoids while waiting for stable resolution of symptoms within one or two weeks.

Hemorrhoid Banding: A Cost-Effectiveness Analysis

BACKGROUND

Hemorrhoid banding is an established treatment for symptomatic internal hemorrhoids with proven efficacy, low cost, and limited discomfort. Although the costs and quality of life following individual banding treatments have been investigated, little is known about cumulative cost and quality of life from sequential banding therapy or how these cumulative costs compare to surgical therapy.

OBJECTIVE

This study aimed to determine the cost-effectiveness of sequential hemorrhoid banding therapy.

DESIGN

A retrospective review of historic banding treatment patterns was performed. Cost estimates and quality-of-life predictions were applied to observed treatment patterns in a decision-analytic cost-effectiveness model to compare sequential banding therapy with hypothetical surgical intervention.

SETTING

A retrospective billing record review for patients treated in a colorectal specialty clinic between 2012 and 2017 was performed.

PATIENTS

Patients initially treated with banding therapy for symptomatic internal hemorrhoids were included.

MAIN OUTCOME MEASURE

The primary outcomes measured were hemorrhoid banding treatment patterns, cost-effectiveness, and net monetary benefit.

RESULTS

Treatment of 2026 patients undergoing hemorrhoid banding identified 94% resolution with sequential banding and 6% requiring delayed surgical intervention. Average cumulative estimated cost for banding therapy was $723 (range, $382-$4430) per patient with an average quality-of-life deficit of -0.00234 (range, -0.00064 to -0.02638) quality-adjusted life-years. Estimates for hypothetical hemorrhoid artery ligation, stapled hemorrhoidopexy, or surgical hemorrhoidectomy found significantly higher cost (3.15×, 4.39×, and 2.75× more expensive) and a significantly worse quality-of-life deficit (1.55×, 5.64×, and 9.45× worse). For patients with persistent disease, continued sequential banding remained the dominant cost-effective therapy.

LIMITATIONS

This cost-effectiveness model relies on a retrospective review of billing records with estimated cost and quality of life.

CONCLUSIONS

Hemorrhoid banding is a valuable treatment modality with favorable cost-effectiveness. The majority of patients selected for banding find resolution without surgery. For patients with persistent disease, further banding procedures remain cost-effective compared with delayed surgical therapy. See Video Abstract at http://links.lww.com/DCR/A982.

BANDA HEMORROIDAL

UN ANÁLISIS DE COSTO-EFECTIVIDAD: La banda para hemorroides es un tratamiento establecido para las hemorroides internas sintomáticas con eficacia comprobada, bajo costo y malestar limitado. Si bien se han investigado los costos y la calidad de vida después de los tratamientos de bandas individuales, se sabe poco sobre el costo acumulativo y la calidad de vida de la terapia de bandas secuencial o cómo estos costos acumulativos se comparan con la terapia quirúrgica.

OBJETIVO

Determinar el costo-efectividad de la terapia secuencial de bandas hemorroidales. DISEÑO:: Se realizó una revisión retrospectiva de la historia de los patrones de tratamiento con bandas. Las estimaciones de costos y las predicciones de la calidad de vida se aplicaron a los patrones de tratamiento observados en un modelo analítico de costo-efectividad para comparar la terapia de bandas secuencial con la intervención quirúrgica hipotética.

AJUSTE

Revisión retrospectiva de los registros de facturación de los pacientes tratados en una clínica de especialidad colorrectal entre 2012 y 2017.

PACIENTES

PRINCIPALES MEDIDAS DE RESULTADO

Patrones de tratamiento con bandas de hemorroides, costo-efectividad y beneficio monetario neto.

RESULTADOS

El tratamiento de 2026 pacientes con bandas identificó una resolución del 94% con bandas secuenciales y el 6% requirió una intervención quirúrgica tardía. El costo promedio acumulado estimado para la terapia de banda fue de $ 723 (Rango: $382-$4430) por paciente con un déficit de calidad de vida promedio de -0.00234 (Rango: -0.00064 a -0.02638) años de vida ajustados por calidad. Las estimaciones para la hipotética ligadura de la arteria hemorroidal, la hemorroidopexia con grapas o la hemorroidectomía quirúrgica encontraron un costo significativamente mayor (3.15×, 4.39×, 2.75× más caro) y un déficit de la calidad de vida significativamente peor (1.55×, 5.64×, 9.45× peor). Para los pacientes con enfermedad persistente, la colocación de bandas secuenciales continuas siguió siendo la terapia rentable dominante.

LIMITACIONES

Este modelo de costo-efectividad se basa en una revisión retrospectiva de los registros de facturación con el costo y la calidad de vida estimados.

CONCLUSIONES

Las bandas de hemorroides son una valiosa modalidad de tratamiento con una favorable relación costo-efectividad. La mayoría de los pacientes seleccionados para terapia con bandas encuentran resolución sin cirugía. Para los pacientes con enfermedad persistente, los procedimientos de colocación de bandas adicionales siguen siendo rentables en comparación con el tratamiento quirúrgico tardío.

Pre-operative assessment of internal mucosal rectal prolapse in internal hemorrhoids: technical details and results from a single institution

BACKGROUND

The aim of the study was to assess safety and efficacy of pre-operative assessment for internal mucosal rectal prolapse (IMRP) in internal hemorrhoids, in order to achieve a tailored transanal stapled surgery.

METHODS

All consecutive patients (January 2011 to December 2014; age 18-80 years), affected by prolapses with II-IV degrees hemorrhoids that underwent Longo procedure with EEA® Auto Suture stapler (Covidien) were included in the present study.

RESULTS

A total of 100 consecutive patients (38 females) were enrolled in the study. Preoperative Visual Analogue Scale pain assessment was 7.33±2.68. The mean duration of the procedure was 34.1±17.8 min, and the median hospital stay was 2 days (range 2-6). No major complication occurred, including relapses of mucosal prolapse. Preoperative prolapse measurement with EEA® EEA® Auto Suture stapler (2.3±0.5 cm) was well correlated direct assessment (2.4±0.6, p<0.001), but a proportional bias was identified, with significant preoperative underestimation of IMRP, particularly for lesions larger than 3 cm (around 10% of actual extent).

CONCLUSIONS

EEA® Auto Suture stapler seems to be safe and effective for a tailored approach to anorectal prolapse due to hemorrhoids. However, it reasonable that its actual impact may have been overestimated, beneficing of the repetitive, direct assessment of the operatory field guaranteed by preoperative IMRP measurement.

Partial Stapled Hemorrhoidopexy Versus Circumferential Stapled Hemorrhoidopexy for Grade III to IV Prolapsing Hemorrhoids: A Randomized, Noninferiority Trial

BACKGROUND

Long-term outcomes and efficacy of partial stapled hemorrhoidopexy are not known.

OBJECTIVE

The purpose of this study was to compare the long-term clinical efficacy and safety of partial stapled hemorrhoidopexy with circumferential stapled hemorrhoidopexy.

DESIGN

This was a parallel group, randomized, noninferiority clinical trial.

SETTINGS

The study was conducted at a single academic center.

PATIENTS

Patients with grade III/IV hemorrhoids between August 2011 and November 2013 were included.

INTERVENTIONS

Three hundred patients were randomly assigned to undergo either partial stapled hemorrhoidopexy (group 1, n = 150) or circumferential stapled hemorrhoidopexy (group 2, n = 150).

MAIN OUTCOME MEASURES

The primary outcome was the rate of recurrent prolapse at a median follow-up period of 5 years with a predefined noninferiority margin of 3.75%. Secondary outcomes included incidence and severity of postoperative pain, fecal urgency, anal continence, and the frequency of specific complications, including anorectal stenosis and rectovaginal fistula.

RESULTS

The visual analog scores in group 1 were less than those in group 2 (p < 0.001). Fewer patients in group 1 experienced postoperative urgency compared with those in group 2 (p = 0.001). Anal continence significantly worsened after both procedures, but the difference between preoperative and postoperative continence scores was higher for group 2 than for group 1. Postoperative rectal stenosis did not develop in patients in group 1, although it occurred in 8 patients (5%) in group 2 (p = 0.004). The 5-year cumulative recurrence rate between group 1 (9% (95% CI, 4%-13%)) and group 2 (12% (95% CI, 7%-17%)) did not differ significantly (p = 0.137), and the difference was within the noninferiority margin (absolute difference, -3.33% (95% CI, -10.00% to 3.55%)).

LIMITATIONS

The study was limited because it was a single-center trial.

CONCLUSIONS

Partial stapled hemorrhoidopexy is noninferior to circumferential stapled hemorrhoidopexy for patients with grade III to IV hemorrhoids at a median follow-up period of 5 years. However, partial stapled hemorrhoidopexy was associated with reduced postoperative pain and urgency, better postoperative anal continence, and minimal risk of rectal stenosis.

Pathophysiology of internal hemorrhoids

Hemorrhoidal disease is a fairly common and debilitating clinical entity. Despite centuries’ of attempts to shed light on its pathophysiology, to cure those affected and to improve sufferers’ quality of life, many aspects of the disease remain elusive. Individual beliefs and historical legends, accompanied by undocumented theories, have established and perpetuated the confusion regarding the mechanisms leading to the development of the disease and the rules governing its treatment. Hemorrhoids are classified as internal or external and are viewed as a disease when they become symptomatic. Returning to basic medical sciences, this mini-review focuses on internal hemorrhoids and aims to define the histology and anatomy of the normal and abnormal internal hemorrhoidal plexus and to encourage clinicians to comprehend the pathophysiology of the disease. If doctors can understand the pathophysiology of hemorrhoidal disease, they will be able to clarify the nature of the associated symptoms and complications and to make the correct therapeutic decision.

Long-term results after stapled hemorrhoidopexy: a survey study with mean follow-up of 12 years

BACKGROUND

Hemorrhoidal prolapse is a common benign disease. The introduction of circular-stapled hemorrhoidopexy as an alternative to the conventional hemorrhoidectomy led to a new spectrum of postoperative outcomes and complications. The aim of the present study was to evaluate long-term results after stapled hemorrhoidopexy.

METHODS

All the patients who had stapled hemorrhoidopexy using a PPH03 stapler, from January 2003 to December 2005, were retrospectively collected in a dedicated database. Between March and May 2016, all the patients were asked by phone to complete a questionnaire. The study evaluated anatomical recurrence, symptom recurrence and frequency, and satisfaction after surgery. The postoperative complications recorded were hemorrhage, hematoma, urinary retention, anastomotic stenosis, persistent anal pain, tenesmus, and impaired anal continence evaluated also with the Faecal Incontinence Severity Index score.

RESULTS

One hundred and ninety four patients were identified and 171 completed the questionnaire. The mean follow-up was 12 ± 0.8 years (range 11-13 years). Anatomical self-reported prolapse recurrence was 40.9% (n = 70). In 75.6% (n = 129) of patients, the severity and frequency of symptoms improved. The overall complication rate was 56.7% (n = 40) with a serious adverse event rate of 8.7% (n = 15). The overall tenesmus rate was 38.2% (n = 65) and the overall impaired continence rate was 39.1% (n = 67). Medical therapy was still required occasionally by 40.3% (n = 69) of the patients and 9.3% (n = 16) of the patients underwent surgery for recurrence. Patient satisfaction rate was good (≥ 3 on a scale of 1 to 5) in 81.2% (n = 139) of cases.

CONCLUSIONS

The study showed that stapled hemorrhoidopexy using the first-generation devices is safe and feasible but associated with a high recurrence and incontinence rate. More stringent selection criteria in association with the use of large volume devices can lead to better results in the future.

Stapled Hemorrhoidopexy: Results at 10-Year Follow-up

BACKGROUND

Despite the advantages of stapled hemorrhoidopexy reported in the literature in terms of postoperative pain, hospital stay, and duration of convalescence, it was described to have a higher recurrence rate compared with conventional hemorrhoidectomy.

OBJECTIVE

The aim of this study was to evaluate clinical outcomes and patient satisfaction after stapled hemorrhoidopexy at 10-year follow-up.

DESIGN

This was a retrospective cohort analysis conducted on prospectively collected data.

SETTINGS

The study was conducted at a single tertiary care center.

PATIENTS

Eighty-six consecutive patients treated with stapled hemorrhoidopexy for grade 3 hemorrhoidal prolapse between January and December 2006 were included.

MAIN OUTCOME MEASURES

Patients satisfaction and recurrence rates were measured.

RESULTS

Eighty-six patients (45 men and 41 women; median age, 49 y (range, 31-74 y)) underwent stapled hemorrhoidopexy. Eight patients had urinary retention during the immediate postoperative period, and 2 patients required a reoperation for suture line bleeding. The median hospital stay was 12 hours (range, 12-96 h). No suture line dehiscence, rectovaginal fistula, pelvic sepsis, anal abscess, or anal stenosis was recorded during the follow-up. Seventy-seven patients (90%) completed the expected follow-up, with a median duration of 119.0 months (range 115.4-121.8 mo). Among them, 30 patients (39%) experienced a recurrent hemorrhoidal prolapse, 8 of whom needed a reoperation. Thirty-four patients (44%) reported urge to defecate with a median visual analog scale of 1 (range, 1-7). Six patients (8%) reported gas leakage at the last follow-up visit, whereas no liquid or solid stool leakage was recorded. Satisfaction rate at 10-year follow-up was 68%.

LIMITATIONS

The study was limited by its small sample size and lack of a control group.

CONCLUSIONS

The high recurrence rate and low patient satisfaction rate showed that stapled hemorrhoidopexy reduces its efficacy in the long-term. See Video Abstract at http://links.lww.com/DCR/A510.

Transanal Hemorrhoidal Dearterialization Versus Stapled Hemorrhoidopexy: Long-Term Follow-up of a Prospective Randomized Study

Aim. This study aims to compare the early and late outcomes of transanal hemorrhoidal dearterialization (THD) versus stapled hemorrhoidopexy (SH) for the treatment of hemorrhoidal disease. Methods. From January 2013 to December 2014, 100 patients—50 patients on each arm—were randomly allocated to THD or SH groups. The inclusion criteria were grade III and IV hemorrhoids diagnosed by clinical examination and proctoscopy. The primary outcome was to compare the recurrence rate with a minimum follow-up of 2 years, and the secondary outcome was to compare complications rate, time to return to work postsurgery, procedure length, and patient’s satisfaction between the 2 techniques. Results. The mean follow-up period was 33.7 ± 7.6. The recurrence rate was 4% in the SH group and 16% in the THD group ( P = .04). There was no difference in the intraoperative and postoperative complications rate; the pain score was significantly higher in the THD group. The mean operative time was significantly shorter in the SH group compared with the THD group. Patients in the THD group returned to work or routine activities significantly later compared with patients in the SH group. The overall satisfaction rate was also higher in the SH group. Conclusion. Both procedures are simple and easy to perform for the treatment of grade III and IV hemorrhoids. SH showed better results in terms of lower rate of recurrence, lower postoperative pain, quicker return to work, and higher patient satisfaction.

Prospective, Multicenter Randomized Controlled Trial Comparing Two Hemorrhoidopexy Staplers: The HEMOSTASIS Study

The objective of this study was to compare two hemorrhoidopexy staplers (EEA versus PPH03). Stapled hemorrhoidopexy is a treatment option for patients with symptomatic internal hemorrhoids who have failed more conservative measures. However, staple line bleeding remains common. Recent improvements in stapler design have attempted to reduce intraoperative bleeding and the need for intervention. HEMOSTASIS is a prospective, multicenter, 1:1 randomized controlled trial. Twelve hospital centers in the United States enrolled participants between 18 and 85 years of age with symptomatic grades 2 to 3 internal hemorrhoids. The primary end point was intraoperative bleeding, defined as bleeding requiring intervention (e.g., placement of sutures, cauterization, or ligation to achieve hemostasis). Secondary end points included staple line location, postoperative pain, quality of life, operative time, length of hospital stay, adverse events, and complication rates. On the primary end point, the rates of intraoperative bleeding requiring intervention were 41.0% (32 of 78) with EEA and 70.4% (50 of 71) with PPH (P &lt; 0.001). Treatment for active bleeding was required in 30.8% versus 57.7% (P &lt; 0.001) in the EEA and PPH arms, respectively. There were no significant differences between groups in postoperative pain. Adverse events and perioperative complication rates were generally mild/moderate and were similar between groups: 74.1% (60 of 81) of patients in the EEA group reported at least one adverse event versus 80.9% (55 of 68) in the PPH group (P = 0.32). Intraoperative bleeding occurred less often after stapled hemorrhoidopexy with the EEA stapler compared with the PPH03 stapler. Intervention to achieve hemostasis was required less often with the EEA stapler.

Procedure for prolapse and hemorrhoids (PPH) with low rectal anastomosis using a PPH 03 stapler: low rate of recurrence and postoperative complications

PURPOSE

The procedure for prolapse and hemorrhoids (PPH) has the advantage of less postoperative pain. However, serious postoperative complications have been reported after PPH, and the postoperative recurrence rate is high in comparison with conventional Milligan-Morgan hemorrhoidectomy (MMH). The purpose of this study was to evaluate PPH with low rectal anastomosis (PPH-LA) in comparison with the original PPH and MMH.

METHODS

Among a total of 1315 patients with hemorrhoids, MMH was conducted in 322, original PPH using a PPH 01 stapler (PPH01) in 63, PPH-LA using 01 (PPH-LA01) in 236, 03 (PPH-LA03) in 649, and sclerotherapy (SCL) in 45.

RESULTS

Length of hospital stay and number of working days lost were significantly greater for MMH than for any form of PPH. The rate of massive postoperative bleeding was significantly lower after PPH-LA03 than after PPH01 or PPH-LA01. No serious postoperative complications occurred after any form of PPH. A significantly higher proportion of patients complained of continued prolapse after PPH01 than after MMH, PPH-LA01, or -LA03. The 5- and 16-year postoperative cumulative recurrence rates after PPH-LA03 were significantly lower than after PPH01.

CONCLUSIONS

The postoperative cumulative recurrence rate after PPH-LA03 is as low as that after MMH for up to 16 years, and compared with the original PPH01, the effectiveness is higher and the postoperative cumulative recurrence rate for up to 16 years is significantly lower. We conclude that PPH-LA03 is a superior procedure for hemorrhoids, having less postoperative pain and a low rate of recurrence.

Implementation of a New High-Volume Circular Stapler in Stapled Anopexy for Hemorrhoidal Disease: Is Patient's Short-Term Outcome Affected by a Higher Volume of Resected Tissue?

BACKGROUND

Stapled anopexy is a safe technique for the treatment of hemorrhoids but carries a higher risk of recurrence, which might be caused due to the limited volume of resected tissue. In this study, we investigated the introduction of a high-volume circular stapling device; in particular whether an increased amount of resected tissue could affect patients' short-term postoperative outcome.

METHODS

Between 2011 and 2015, stapled anopexy was performed for hemorrhoids and/or anal prolapse in 141 patients (n = 25 conventional PPH-3©-stapler versus n = 116 high-volume CHEX©-stapler). In this prospectively collected dataset, operation details and short-term postoperative outcome were compared.

RESULTS

With the high-volume stapler, a significantly higher amount of tissue was resected: 9.8 g (range 6.2-11.4) vs. 6.4 g (range 4.9-8.8) with the conventional stapler, p < 0.01. Postoperative short-term outcome did not differ in terms of readmission and complication rates. In all 5 patients who underwent a redo operation for residual hemorrhoids or prolapse, the high-volume stapler was used in the primary operation.

CONCLUSION

A high-volume stapling device for stapled anopexy was introduced safely with a significantly higher amount of resected tissue without a worse short-term outcome. However, it remains unclear whether higher stapling volumes may lead to improved long-term outcome with less reinterventions.

Comparison of clinical outcomes of multi-point umbrella suturing and single purse suturing with two-point traction after procedure for prolapse and hemorrhoids (PPH) surgery

OBJECTIVES

To compare the clinical outcomes of multipoint umbrella suture and single-purse suture with two-point traction after procedure for prolapse and hemorrhoids surgery (PPH) for the treatment of mixed hemorrhoids.

METHODS

Ninety patients were randomly divided into a PPH plus single-purse suture group (Group A) and a PPH plus multipoint umbrella suture (Group B). All operations were performed by an experienced surgeon. Operation time, width of the specimen, hemorrhoids retraction extent, postoperative pain, postoperative bleeding, and length of hospitalization were recorded and compared. Statistical analysis was conducted by t-test and χ2 test.

RESULTS

There were no significant differences in sex, age, course of disease, and degree of prolapse of hemorrhoids between the two groups. The operative time in Group A was significantly shorter than that in Group B (P < 0.05). However, the incidence rates of submucosal hematoma and incomplete hemorrhoid core retraction were significantly lower in Group B (P < 0.05), whereas the width of the specimens in Group B was greater than that in Group A (P < 0.05). There were fewer redundant skin tags in Group B at three months follow-up. No significant difference in postoperative pain, postoperative bleeding, and time of hospital stay (P > 0.05 for all comparisons) was observed.

CONCLUSION

The multipoint umbrella suture showed better clinical outcomes because of its targeted suture according to the extent of hemorrhoid prolapse.

LONG TERM RESULTS AFTER STAPLED HEMORRHOIDOPEXY ALONE AND COMPLEMENTED BY EXCISIONAL HEMORRHOIDECTOMY: A RETROSPECTIVE COHORT STUDY

Background:

Stapled hemorrhoidopexy is associated with less postoperative pain and faster recovery. However, it may be associated with a greater risk of symptomatic recurrence. We hypothesized that undertaking a limited surgical excision of hemorrhoid disease after stapling may be a valid approach for selected patients.

Aim:

To compare long-term results after stapled hemorrhoidopexy with and without complementation with closed excisional technique.

Method:

In a retrospective uni-institutional cohort study, sixty-five (29 men) patients underwent stapled hemorrhoidopexy and 21 (13 men) underwent stapled hemorrhoidopexy with excision. The same surgeons operated on all cases. Patients underwent stapled hemorrhoidectomy associated with excisional surgery if symptoms attributable to external hemorrhoid piles were observed preoperatively, or if residual prolapse or bulky external disease was observed after the firing of the stapler. A closed excisional diathermy hemorrhoidectomy without vascular ligation was utilized in all complemented cases. All clinical variables were obtained from a questionnaire evaluation obtained through e-mail, telephone interview, or office follow-up.

Results:

The median duration of postoperative follow-up was 48.5 (6-40) months. Patients with grades 3 and 4 hemorrhoid disease were operated on more frequently using stapled hemorrhoidopexy complemented with excisional technique (95.2% vs. 55.4%, p=0.001). Regarding respectively stapled hemorrhoidopexy and stapled hemorrhoidopexy complemented with excision, there was no difference between the techniques in relation to symptom recurrence (43% and 33%, p=0.45) and median interval between surgery and symptom recurrence (30 (8-84) and 38.8 (8-65) months, p=0.80). Eight (12.3%) patients were re-operated after stapled hemorrhoidopexy and 2 (9.6%), after hemorrhoidopexy with excision (p=0.78). Patient distribution in both groups according to the degree of postoperative satisfaction was similar (p=0.97).

Conclusion:

Stapled hemorrhoidopexy combined with an excisional technique was effective for more advanced hemorrhoid disease. The combination may have prevented symptomatic recurrence associated to stapled hemorrhoidopexy alone.

Zusammenfassung. Der auf Höhe der Linea dentata gelegene Corpus cavernosum recti spielt eine tragende Rolle bei der Regulierung der Feinkontinenz. Kommt es zu einer pathologischen Vergrösserung des Corpus cavernosum verbunden mit Symptomen, spricht man von einem Hämorrhoidalleiden. Das Hämorrhoidalleiden ist eine Volkskrankheit mit einer Inzidenz von ca. 40 %, wobei die Rate an Selbsttherapien hoch ist. Im klinischen Alltag fällt der stadienadaptierten Therapie eine wichtige Rolle zu: Hämorrhoiden Grad I sind die Domäne der konservativen Therapie, Hämorrhoiden Grad II können in Abhängigkeit der Schwere der Symptome konservativ oder operativ angegangen werden. Hämorrhoiden Grad III und Grad IV sollten einer Operation zugeführt werden.

Rectal free perforation after stapled hemorrhoidopexy: A case report of laparoscopic peritoneal lavage and repair without stoma

•

Stapled hemorrhoidopexy (SH) is common treatment for prolapsed hemorrhoid.

•

Unexpected abdominal pain following SH may related rectal perforation.

•

Laparoscopic repair of rectal perforation is feasible in selective patients.

•

A transanal rectal tube keep in several days may substitute diverting stoma.

Introduction

Stapled hemorrhoidopexy is widely performed for treatment of prolapsed hemorrhoids because of advantages, including shorter hospital stay and less discomfort, compared with conventional hemorrhoidectomy. However, it can have severe adverse effects, such as rectal bleeding, perforation, and sepsis.

Presentation of case

We report the case of a healthy 28-year-old man who presented to the emergency department with sudden-onset diffuse abdominal pain and hematochezia. He had undergone stapled hemorrhoidopexy 5 days earlier and was discharged after an uneventful postoperative course. For the present condition, after immediate evaluation, we successfully performed emergency laparoscopic repair of the rectal perforation without any stoma. His postoperative course was uneventful, and he was discharged on postoperative day 16.

Discussion

This is a rare case of rectal perforation after stapled hemorrhoidopexy in which the perforation was treated successfully by laparoscopic repair. In most cases of rectal perforation following stapled hemorrhoidopexy, surgeons perform open laparotomy and create diverting stoma. However, our patient underwent totally laparoscopic lavage and primary closure without diverting stoma. Multiple investigators have reported that laparoscopic lavage for perforated diverticulitis may be an appropriate treatment option. Factors favoring this approach include early surgery, young age, sufficient irrigation, and meticulous primary closure.

Conclusion

Stapled hemorrhoidopexy can have severe adverse effects, such as rectal bleeding, pelvic sepsis, and rectal perforation, which are potentially life-threatening. Laparoscopic lavage and primary repair without stoma can be performed successfully in select patients with rectal perforation following stapled hemorrhoidopexy.
