Pelvic floor rehabilitation is frequently recommended for defecation disorders, in both constipation and fecal incontinence. However, the lack of patient selection, together with the variety of rehabilitation methods and protocols, often jeopardize the results of this approach, causing difficulty in evaluating outcomes and addressing proper management, and above all, in obtaining scientific evidence for the efficacy of these methods for specific indications. The authors represent different gastroenterological and surgical scientific societies in Italy, and their aim was to identify the indications and agree on treatment protocols for pelvic floor rehabilitation of patients with defecation disorders. This was achieved by means of a modified Delphi method, utilizing a working team (10 members) which developed the statements and a consensus group (15 members, different from the previous ones) which voted twice also suggesting modifications of the statements.

Background According to Rome criteria, chronic constipation (CC) includes functional constipation (FC) and irritable bowel syndrome with constipation (IBS-C). Some patients do not meet these criteria (No Rome Constipation, NRC). The aim of the study was is to evaluate the various clinical presentation and management of FC, IBS-C and NRC in Italy. Methods During a 2-month period, 52 Italian gastroenterologists recorded clinical data of FC, IBS-C and NRC patients, using Bristol scale, PAC-SYM and PAC-QoL questionnaires. In addition, gastroenterologists were also asked to record whether the patients were clinically assessed for CC for the first time or were in follow up. Diagnostic tests and prescribed therapies were also recorded. Results Eight hundred seventy-eight consecutive CC patients (706 F) were enrolled (FC 62.5%, IBS-C 31.3%, NRC 6.2%). PAC-SYM and PAC-QoL scores were higher in IBS-C than in FC and NRC. 49.5% were at their first gastroenterological evaluation for CC. In 48.5% CC duration was longer than 10 years. A specialist consultation was requested in 31.6%, more frequently in IBS-C than in NRC. Digital rectal examination was performed in only 56.4%. Diagnostic tests were prescribed to 80.0%. Faecal calprotectin, thyroid tests, celiac serology, breath tests were more frequently suggested in IBS-C and anorectal manometry in FC. More than 90% had at least one treatment suggested on chronic constipation, most frequently dietary changes, macrogol and fibers. Antispasmodics and psychotherapy were more frequently prescribed in IBS-C, prucalopride and pelvic floor rehabilitation in FC. Conclusions Patients with IBS-C reported more severe symptoms and worse quality of life than FC and NRC. Digital rectal examination was often not performed but at least one diagnostic test was prescribed to most patients. Colonoscopy and blood tests were the “first line” diagnostic tools. Macrogol was the most prescribed laxative, and prucalopride and pelvic floor rehabilitation represented a “second line” approach. Diagnostic tests and prescribed therapies increased by increasing CC severity.

Background Anal fissure (AF) is a common cause of anal pain with a tendency not to heal spontaneously because of ischemia of the anoderm caused by sphincter spasm. Lateral internal sphincterotomy, while very effective, can cause fecal incontinence and chemical sphincterotomy by application of cream may have discouraging side effects and/or low efficacy. The aim of this prospective multicenter study was to evaluate the safety and effectiveness of a new medical treatment based on Emulgel cream, with emollient, soothing and protective agents, on AF healing. Methods Consecutive patients with AF treated in nine coloproctology units during 6 months entered the study on topical treatment with Levorag® Emulgel (THD S.p.A Correggio (RE), Italy). Before treatment, they had a proctologic examination and pain was measured using a visual analog scale. THD Levorag® Emulgel was applied every 12 h for 40 days. Monitoring was scheduled at 10, 20 and 40 days. At time 0 and at the end of treatment, patients underwent anorectal manometry, if possible. Results Two hundred eighty-four AF patients were recruited (171 acute fissures). Complete healing was achieved in 47.9 % of the cases, an improvement in 31.0 % (global efficacy 78.9 %). In patients with acute fissure, the rate of efficacy was 89.4 % (complete healing: 64.3 %, improvement: 25.1 %), in those with chronic fissure the rate of efficacy was 62.8 % (complete healing: 23 %, improvement: 39.8 %), p

Objective Fibrin glue treatment of anal fistulae has been proposed to minimize the risk of faecal incontinence but its acceptance by coloproctologists is still poor because the published data is controversial. Therefore, we carried out a prospective randomized crossover trial comparing treatment with a commercial fibrin glue to classical seton treatment, with healing rate, hospital stay, healing time, faecal incontinence and postoperative pain as study outcomes. Method Sixty-four homogeneous patients with trans-sphincteric anal fistulae referred to seven colorectal units were randomized to undergo fibrin glue (39 patients) or seton (25 patients) treatment. Patients failing to heal after treatment with fibrin glue were re-randomized to undergo a second injection with glue or seton treatment. Results Sixty-two of the 64 patients completed the minimum 1-year follow-up period. Twenty-one of 24 patients healed in the seton group compared with 15/38 in the fibrin glue group (P = 0.0007). The 23 failures after glue treatment were re-randomized to have a second glue injection (eight patients) or a seton treatment (15 patients). Four of the eight (50%) patients treated with a second injection of glue, and nine out of the 15 (60%) patients in the seton group, healed. Patients treated with fibrin glue reported less postoperative pain and had a shorter hospital stay than patients treated with a seton; furthermore, faecal continence and anal manometry significantly worsened after seton treatment. Conclusion Seton treatment has a significantly higher probability of success compared with fibrin glue treatment but poses a higher risk of faecal incontinence. Fibrin glue could be considered as a first line of treatment for patients at risk of faecal incontinence or other comorbidities.

Objective Surgical treatment of constipation and obstructed defecation (OD) carries frequent recurrences, as OD is an ‘iceberg syndrome’ characterized by ‘underwater rocks’ or occult diseases which may affect the outcome of surgery. The aim of this study was to evaluate occult disorders, in order to alert the clinician of these and minimize failures. Method One hundred consecutive constipated patients with OD symptoms, 81 women, median age 52 years, underwent perineal examination, proctoscopy, anorectal manometry and anal/vaginal ultrasound (US). Anorectal physiology and imaging tests were also carried out when indicated, as well as psychological and urogynaecological consultations. Symptoms were graded using a modified 1–20 constipation score. Both evident (e.g. rectocele) and occult (e.g. anismus) diseases were prospectively evaluated using a novel ‘iceberg diagram’. The type of treatment, whether conservative or surgical, was also recorded. Results Fifty-four (54%) patients had both mucosal prolapse and rectocele. All patients had at least two occult OD-related diseases, 66 patients had at least three of them: anxiety–depression, anismus and rectal hyposensation were the most frequent (66%, 44% and 33%, respectively). The median constipation score was 11 (range 2–20), the median number of ‘occult disorders’ was 5 (range 2–8). Conservative treatment was carried out in most cases. Surgery was carried out in 14 (14%) patients. Conclusion The novel ‘iceberg diagram’ allowed the adequate evaluation of OD-related occult diseases and better selection of patients for treatment. Most were managed conservatively, and only a minority were treated by surgery.

The aim of this paper is to present the results of the Italian Society of Colorectal Surgery [or Società Italiana di Chirurgia Colorettale (SICCR)] Logbook of adverse events (AE) occurring in relation to emerging technologies in coloproctology (ETCs), over a 3-year period.A total of 245 AE were reported (patients age: mean = 49.6 years, range = 20-75 years; gender: 155 = F, 90 = M). The "observations" originated from the same institution of the AEs in 44 cases (18.0%), while 201 patients (82.0%) had been operated on somewhere else.The three most reported ETCs were: Procedure for prolapsed haemorrhoids (PPH) (n = 120-48.9%), stapled transanal rectal resection (STARR (n = 96-39.2%), and transanal haemorrhoidal dearterialization (THD) (n = 11-4.5%). PPH, STARR, and THD together accounted for n = 227 (92.6%) observations. For the three main reported ETCs, the various AEs are listed. Chronic pain after PPH was 46/120 (38.3%), and after STARR of 21/96 (21.9%). The overall re-operation rate was n = 135 (55.1%) versus n = 110 (44.9%) no reoperation. In particular, for the three main reported ETCs, n = 68/120 (56.7%) following an AE after PPH, n = 47/94 (50.0%) following an AE after STARR, and n = 6/11 (54.5) following an AE post-THD. The various types of treatment to solve AE after each of the three most observed ETCs are reported in the text.Our results do not allow us to draw statistical conclusions; however, this was not the aim of our survey. ETCs are important, yet they are not without major risks. Manufacturers should help colorectal surgeons to convey the right message to patients.

Background Chronic anal fissure (CAF) is a painful condition that is unlikely to resolve with conventional conservative management. Previous studies have reported that topical treatment of CAF with glyceryl trinitrate (GTN) reduces pain and promotes healing, but optimal treatment duration is unknown. Methods To assess the effect of different treatment durations on CAF, we designed a prospective randomized trial comparing 40 versus 80 days with twice daily topical 0.4% GTN treatment (Rectogesic®, Prostrakan Group). Chronicity was defined by the presence of both morphological (fibrosis, skin tag, exposed sphincter, hypertrophied anal papilla) and time criteria (symptoms present for more than 2 months or pain of less duration but similar episodes in the past). A gravity score (1 = no visible sphincter; 2 = visible sphincter; 3 = visible sphincter and fibrosis) was used at baseline. Fissure healing, the primary endpoint of the study, maximum pain at defecation measured with VAS and maximum anal resting pressure were assessed at baseline and at 14, 28, 40 and 80 days. Data was gathered at the end of the assigned treatment. Results Of 188 patients with chronic fissure, 96 were randomized to the 40-day group and 92 to the 80-day group. Patients were well matched for sex, age, VAS and fissure score. There were 34 (19%) patients who did not complete treatment, 18 (10%) because of side effects. Of 154 patients who completed treatment, 90 (58%) had their fissures healed and 105 (68%) were pain free. There was no difference in healing or symptoms between the 40- and the 80-day group. There was no predictor of fissure healing. A low fissure gravity score correlated with increased resolution of pain (P

Anal endosonography (AES) has become an essential part of the pre-operative diagnostic workup in both organic and functional anal diseases.Nine Italian centres with an average volume activity of10 exams/week each were surveyed with the aim of determining the concordance with respect to indications for the procedure and interpretation of the results.Overall, anal sepsis, faecal incontinence and anorectal tumours were the more common indications for AES while evacuation dysfunctions and anal pain were not always considered indications. All centres use the same diagnostic criteria for simple and complicated perirectal sepsis and sphincteric defects, but adopt different classifications for stage 1 and stage 2 anal tumours. Participants agreed in that lymph-node staging by AES is less precise than tumour staging, especially after chemoradiation therapy.A list of recommendations and guidelines based on the groups's experience has been produced for those radiologists and coloproctologists interested in the use of AES and accreditation of their centres.

The most effective surgical technique for rectocele has not yet been clearly established. A retrospective multicentric study was carried out to compare the long-term results of 3 endorectal techniques (Block, Sarles and stapled) and the perineal levatorplasty, alone and in association, in a series of patients with symptomatic rectocele. From January 1992 to December 1999, 2212 patients with defecation disorders were referred to 5 Italian coloproctology units. An anterior rectocele was clinically diagnosed in 1045 patients and confirmed with defecography. On the basis of clinical and radiological parameters, 317 patients (312 women; mean age, 52.4+/-20.1 years) were selected for surgery. Group 1 consisted of 141 patients (136 women; mean age, 50.4+/-18.8 years) who were submitted to endorectal operations. Group 2 consisted of 126 women (mean age, 52.5+/-19.7 years) who received perineal levatorplasty. Finally, 50 women (mean age, 54.3+/-21.9 years) in Group 3 received endorectal operations associated with perineal levatorplasty. A total of 269 patients were followed postoperatively (mean period, 24.2+/-3.1 months, 27.5+/-5.4 months and, 22.8+/-2.8 months, respectively) with the same questionnaire and clinical examination. Three months after surgery, a defecography examination and anorectal manometry were performed in 136 and 132 patients, respectively. Operative time, hospital stay and time to return to work were significantly higher in Group 3 (p0.001). There was one death in Group 3 due to severe sepsis. Main postoperative complications were: in Group 1, hemorrhage (7.8%, all Sarles), dehiscence of the endorectal suture (5.0%, all Block), distal rectal stenosis (2.1%, 1 stapled, 2 block), and rectovaginal fistula (1.4%, all Sarles); in Group 2, delayed healing of the perineal wound (16.4%); in Group 3 delayed healing of the perineal wound (22.0%), hemorrhage (6%, all Sarles), dehiscence (4.0%), stenosis (2.0%). 17.3% of patients of Group 2 and 22.5% of Group 3 complained of dyspareunia. Postoperative defecography showed a complete absence of the rectocele in 44.1% of patients and reduction of size in the others, without significant differences among the three groups. Manometric pattern was not significantly modified by surgery. Significant symptoms recurred in 5.9% of the patients in Group 1, 6.4% in Group 2, and 5.0% in Group 3. Perineal levatorplasty did not significantly improve obstructed defecation, as it did not allow to excise the rectal mucosal prolapse, and was followed by an high incidence of delayed healing of the perineal wound and dyspareunia. Sarles procedure achieved better control of mucosal prolapse but carried a higher complication rate compared to the others. The association of the perineal levatorplasty with an endorectal technique required significantly longer operative time, and led to a longer hospital stay and time to return to work. In conclusion, the investigated techniques showed different patterns of postoperative complications: bleeding after Sarles, dehiscence after Block, dyspareunia after perineoplasty and fatal gangrene after stapled, but non of them showed a clear superiority over the others in term of clinical or functional results 2 years after surgery.
