Hemorrhoidal Artery Ligation for the Treatment of Grade II-III Hemorrhoids: Is it Worth the Use of Doppler Guide in Long-Term Follow-Up?: A Single-Center Cohort Study.

Background: Hemorrhoidal artery ligation (HAL) may reduce postoperative pain and complications and shorten patients' recovery when compared to standard hemorrhoidectomy. It is unclear if the Doppler guide (DG) is useful in reducing recurrence risk. Objective: To compare two groups of patients (treated with DG-HAL or HAL) in terms of recurrence risk and patients' satisfaction grade. Methods: Between January 1, 2014 and January 31, 2021, 122 patients affected by grade II-III hemorrhoidal prolapse underwent DG-HAL or HAL at Chivasso Hospital, Italy. Mucopexy was routinely performed. After discharge, patients were subjected to 1-week, 1-, 3-, 6-, and 12-month clinical assessment. Thereafter, they were interviewed by telephone annually. Results: Seventy-six (62.3%) DG-HAL and 46 (37.7%) HAL procedures were performed. Median surgical time was 30 (15-45) minutes for DG-HAL versus 25 (15-40) minutes for HAL (P = 0.005). No intraoperative complications occurred. Postoperative bleeding needing surgery occurred in 2 (1.6%) patients in the DG-HAL group. During a median follow-up of 46 months (6-86), we registered 18 (23.7%) recurrences in the DG-HAL group and 13 (28.3%) in the HAL one (P = 0.574). No cases of incontinence or anal stenosis occurred. No significant difference was observed between the two groups in terms of patients' satisfaction. At multivariate analysis, age ≥ 65 years resulted a protective factor for recurrence (odds ratio 0.31; 95% confidence interval 0.09-0.98; P = 0.047). Conclusions: In our study, the use of DG did not reduce recurrence risk. Operative time was significantly increased in the DG-HAL group.

Risk factors for Low Anterior Resection Syndrome (LARS) in patients undergoing laparoscopic surgery for rectal cancer.

BACKGROUND: Total mesorectal excision (TME) represents the "gold standard" of rectal cancer surgery. In locally advanced lesions neoadjuvant treatments (e.g. radiotherapy-nRT, radio chemotherapy-cnRT) have been shown to improve TME oncological results, reducing local recurrences rate. Nevertheless, these treatments have significant functional consequences impacting patients' quality of life (QoL). The resulting syndrome is known as Low Anterior Resection Syndrome (LARS). The purpose of this work was to evaluate the association between risk factors and the development of LARS in a prospective series of laparoscopic sphincter-saving TME. METHODS: The study was conducted as a retrospective observational epidemiological study of a prospective database, including all patients undergoing laparoscopic anterior resection surgery for rectal cancer at our Unit from 1st January 2013 to 31st May 2018. The diagnosis of LARS was performed using the LARS Score. We classified risk factors in patient-related, pre-, intra- and post-operative factors. RESULTS: The sample included 153 consecutive patients. Forty-one were affected by "low" rectal cancer, 74 by "middle" rectal cancer, 38 by "high" rectal cancer. The prevalence of overall LARS (major LARS + minor LARS) in our series was 35.9% (55/153 cases). Association between nRT and overall/major LARS was significant (respectively p = 0.03 and 0.02). Distal localization of tumor was also significantly associated with LARS [overall LARS (p = 0.03), major LARS (p = 0.014)]. CONCLUSIONS: In our study, neoadjuvant radiotherapy and tumor localization resulted independent risk factors for LARS after laparoscopic sphincter-saving TME. Tumor localization in the "middle" and "high" rectum resulted a protective factor compared to the localization in "low" rectum.

Diagnosis and treatment of faecal incontinence: Consensus statement of the Italian Society of Colorectal Surgery and the Italian Association of Hospital Gastroenterologists.

Faecal incontinence is a common and disturbing condition, which leads to impaired quality of life and huge social and economic costs. Although recent studies have identified novel diagnostic modalities and therapeutic options, the best diagnostic and therapeutic approach is not yet completely known and shared among experts in this field. The Italian Society of Colorectal Surgery and the Italian Association of Hospital Gastroenterologists selected a pool of experts to constitute a joint committee on the basis of their experience in treating pelvic floor disorders. The aim was to develop a position paper on the diagnostic and therapeutic aspects of faecal incontinence, to provide practical recommendations for a cost-effective diagnostic work-up and a tailored treatment strategy. The recommendations were defined and graded on the basis of levels of evidence in accordance with the criteria of the Oxford Centre for Evidence-Based Medicine, and were based on currently published scientific evidence. Each statement was drafted through constant communication and evaluation conducted both online and during face-to-face working meetings. A brief recommendation at the end of each paragraph allows clinicians to find concise responses to each diagnostic and therapeutic issue.

Consensus statement AIGO/SICCR diagnosis and treatment of chronic constipation and obstructed defecation (part II: treatment).

The second part of the Consensus Statement of the Italian Association of Hospital Gastroenterologists and Italian Society of Colo-Rectal Surgery reports on the treatment of chronic constipation and obstructed defecation. There is no evidence that increasing fluid intake and physical activity can relieve the symptoms of chronic constipation. Patients with normal-transit constipation should increase their fibre intake through their diet or with commercial fibre. Osmotic laxatives may be effective in patients who do not respond to fibre supplements. Stimulant laxatives should be reserved for patients who do not respond to osmotic laxatives. Controlled trials have shown that serotoninergic enterokinetic agents, such as prucalopride, and prosecretory agents, such as lubiprostone, are effective in the treatment of patients with chronic constipation. Surgery is sometimes necessary. Total colectomy with ileorectostomy may be considered in patients with slow-transit constipation and inertia coli who are resistant to medical therapy and who do not have defecatory disorders, generalised motility disorders or psychological disorders. Randomised controlled trials have established the efficacy of rehabilitative treatment in dys-synergic defecation. Many surgical procedures may be used to treat obstructed defecation in patients with acquired anatomical defects, but none is considered to be the gold standard. Surgery should be reserved for selected patients with an impaired quality of life. Obstructed defecation is often associated with pelvic organ prolapse. Surgery with the placement of prostheses is replacing fascial surgery in the treatment of pelvic organ prolapse, but the efficacy and safety of such procedures have not yet been established.

Consensus statement AIGO/SICCR: diagnosis and treatment of chronic constipation and obstructed defecation (part I: diagnosis).

Chronic constipation is a common and extremely troublesome disorder that significantly reduces the quality of life, and this fact is consistent with the high rate at which health care is sought for this condition. The aim of this project was to develop a consensus for the diagnosis and treatment of chronic constipation and obstructed defecation. The commission presents its results in a "Question-Answer" format, including a set of graded recommendations based on a systematic review of the literature and evidence-based medicine. This section represents the consensus for the diagnosis. The history includes information relating to the onset and duration of symptoms and may reveal secondary causes of constipation. The presence of alarm symptoms and risk factors requires investigation. The physical examination should assess the presence of lesions in the anal and perianal region. The evidence does not support the routine use of blood testing and colonoscopy or barium enema for constipation. Various scoring systems are available to quantify the severity of constipation; the Constipation Severity Instrument for constipation and the obstructed defecation syndrome score for obstructed defecation are the most reliable. The Constipation-Related Quality of Life is an excellent tool for evaluating the patient's quality of life. No single test provides a pathophysiological basis for constipation. Colonic transit and anorectal manometry define the pathophysiologic subtypes. Balloon expulsion is a simple screening test for defecatory disorders, but it does not define the mechanisms. Defecography detects structural abnormalities and assesses functional parameters. Magnetic resonance imaging and/or pelvic floor sonography can further complement defecography by providing information on the movement of the pelvic floor and the organs that it supports. All these investigations are indicated to differentiate between slow transit constipation and obstructed defecation because the treatments differ between these conditions.

Is sacral nerve stimulation an effective treatment for chronic idiopathic anal pain?

BACKGROUND: Chronic idiopathic anal pain is a common, benign symptom, the etiology of which remains unclear. Traditional treatments are often ineffective. This study investigated the efficacy of sacral nerve stimulation in treating chronic idiopathic anal pain. METHODS: Twelve patients (10 women and 2 men; mean age, 61.0 +/- 10.3 years; range, 48-82 years) implanted with a permanent device for sacral nerve stimulation were followed in the Italian Group for Sacral Neuromodulation (GINS) Registry. All patients had frequent chronic anal or perianal pain; 75 percent had previously undergone pelvic surgery. Pharmacologic and rehabilitative therapy had yielded poor results. Changes from baseline to last follow-up examination were evaluated for scores on a visual analog pain scale (0-10) and the Short-Form 36 (SF-36) health status questionnaire. Manometric measurements recorded at last follow-up were compared with preimplantation values. RESULTS: In one patient, the permanent device was removed because of technical failure. After a mean follow-up of 15 (range, 3-80) months, visual analog pain scores had significantly improved (from 8.2 +/- 1.7 to 2.2 +/- 1.3, P < 0.001). SF-36 physical component scores increased from 26.27 +/- 5.65 to 38.95 +/- 9.08, P < 0.02). Scores on the mental component showed improvement, although not significant. Postimplantation changes in manometric functional data were not significant, but sensitivity thresholds showed a considerable decrease. CONCLUSIONS: Long-term follow-up data showing improvements in scores on the visual analog pain scale and quality of life questionnaire indicate that, before adopting more aggressive surgical procedures, SNS should be considered for patients with chronic idiopathic anal pain in whom pharmacologic and biofeedback treatments have failed to produce effective results.

[So-called "dense-vascularised" peritoneal adhesions: clinical and aetiopathogenetic considerations]. / Le aderenze peritoneali cosiddette carnose: considerazioni cliniche ed etiopatogenetiche.

In the daily clinical practice of surgeons operating electively or, more frequently, in the emergency setting, within the abdominal cavity and pelvis, the detection of an intestinal adhesive disorder is frequent and is capable of causing numerous complications and subsequent reintervention. We report three cases of female patients referred to our observation for bowel subocclusion due to adhesive syndrome. After laparotomy, which revealed the presence of singular tenacious fibrovascular adhesions, the patients were subjected to immunohistochemical and receptor analysis yielding a diagnosis of leiomyomatosis peritonealis disseminata. The simultaneous combination of high levels of exogenous female hormones (hormone replacement therapy or prolonged exposure to oral contraceptives) or endogenous hormones (as happens during pregnancy), a genetic predisposition (including genetic malformations) and previous surgery (peritoneal trauma), as evidenced in our patients, all seem to play a key role in the pathogenesis of so-called "dense-vascularised", particularly tenacious adhesions responsible for the activation of multipotent mesenchymal submesothelial peritoneal cells. This striking macroscopic picture, when related to the anatomico-pathological description, is the basis of the pathological entity known as leiomyomatosis peritonealis disseminata.

[Reconstruction of the inguinal ligament in recurrent inguinal hernia using the "three-sheet" technique]. / Ricostruzione del legamento inguinale nelle ernie in g nalirecidive mediante la tecnica a "tre fogli".

Destruction of the groin ligament is an unusual occurrence, often of traumatic or surgical origin. In the event of recurrent inguinal hernia with a destroyed inguinal ligament, the reconstruction of the wall with the surgical techniques currently available yields prognostically unfavourable results with frequent recurrence in only a short space of time. The aim of this report was to present a hernioplasty technique using the "three-sheet" implant involving reduction of the hernia sac and the affixing of two reinforcement nets in Prolene in an attempt to reconstruct the destroyed groin ligament. The three-sheet prosthesis simply consists of three sheets positioned in such a way (two polypropylene prosthesis are sutured one on top of the other perpendicularly and medially) as to form a new inguinal ligament; the first sheet reinforces the wall, reconstructing the posterior wall of the canal, and the second and third sheets support the peritoneum as in a hammock. From September 1995 to July 2006, 11 patients underwent such reconstruction operations in our division, 8 of them for recurrent inguinal hernia for multiple failure, 1 for an inguinal hernia with Cloquet's adenopathy and 2 secondary to femoro-femoral and iliac-femoral by-passes. To date, after a mean follow-up of 5 years, no recurrence has taken place. This method has proved safe and effective, with minimal risk of trauma and complications, and may therefore be indicated for the management of recurrent inguinal hernia with rupture of the inguinal ligament.
