Temporal trends and treatment patterns in anal fissure management: insights from a multicenter study in Italy.

INTRODUCTION: Anal fissure (AF) poses a common challenge in clinical practice, prompting various treatment approaches. This multicenter study, conducted by the Italian Society of Colorectal Surgery, aimed to assess treatment trends in AF over a 10 year period. METHODS: A survey of proctologists and retrospective analysis of patient records were conducted to evaluate treatment modalities and outcomes across six different clinical scenarios based on AF presentation (acute/chronic) stratified by sphincter function (normal/hypertonic/hypotonic). RESULTS: Analysis of data from 17 principal investigators and 22,016 patients revealed significant variability in treatment approaches, influenced by factors such as symptom duration, anal tone, and surgeon preference. Conservative treatments were commonly utilized, while surgical interventions were reserved for refractory cases. Specifically, pharmaceutical treatment was administered to 66-75% of patients in cases of acute AF and 63-67% for chronic AF, while 10-15% underwent anal dilation, and < 2% received botulinum toxin injection. Among medical treatments, nifedipine with lidocaine and glycerin film-forming ointments were the most utilized. The most performed surgical techniques were fissurectomy and anoplasty, except for patients with chronic AF and hypertonic sphincter where sphincterotomy prevailed. Trends in treatment utilization varied depending on the clinical scenario, with notable shifts observed over time. CONCLUSIONS: This study provides insights into the evolving landscape of AF management, highlighting the need for further research to elucidate optimal treatment strategies and improve patient outcomes.

A multicentre, open-label, single-arm phase II trial of the efficacy and safety of sclerotherapy using 3% polidocanol foam to treat second-degree haemorrhoids (SCLEROFOAM).

BACKGROUND: The aim of the present study was to evaluate the efficacy and safety of 3% polidocanol foam for treating 2nd-degree haemorrhoids. METHODS: A multicentre, open-label, single-arm, phase 2 trial involving 10 tertiary referral centres for haemorrhodal disease (HD) was performed. Between January and June 2019, patients with 2nd-degree haemorrhoids were prospectively included in this study. The primary outcome was to establish the success rate after one sclerotherapy session in terms of complete resolution of bleeding episodes one week after the injection. The Hemorrhoidal Disease Symptom Score (HDSS), the Short Health Scale for HD (SHS-HD) score and the Vaizey incontinence score were used to assess symptoms and their impact on quality of life and continence. Pain after the procedure, subjective symptoms and the amount and type of painkillers used were recorded. Patients were followed up for 1 year. RESULTS: There were 183 patients [111 males; 60.7%, mean age 51.3 ± 13.5 (18-75) years]. Complete resolution of bleeding was reached in 125/183 patients (68.3%) at 1 week and the recurrence rate was 12% (15/125). Thirteen patients (7.4%) underwent a second sclerotherapy session, while only 1 patient (1.8%) had to undergo a third session. The overall 1-year success rate was 95.6% (175/183). The HDSS and the SHS score significantly improved from a median preoperative value of 11 and 18 to 0 and 0, respectively (p < 0.001). There were 3 episodes of external thrombosis. No serious adverse events occurred. CONCLUSIONS: Sclerotherapy with 3% polidocanol foam is a safe, effective, painless, repeatable and low-cost procedure in patients with bleeding haemorrhoids.

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

Pilonidal disease (PD) is a relatively common, benign but challenging condition of the natal cleft. This consensus statement was drawn up by a panel of surgeons, identified by the Italian Society of Colorectal Surgery (SICCR) as having a "special interest" in PD, with the aim of recommending the best therapeutic options according to currently available scientific evidence. A three-step modified-Delphi process was adopted, implying: (1) choice of the panelists; (2) development of a discussion outline and of target issues; and (3) a detailed systematic review of the current literature. The agreement/disagreement level was scored on a five-point Likert scale as follows: "A + : strongly agree; A-: agree; N: unsure/no opinion; D-: disagree; D + : strongly disagree. Each panelist contributed to the production of this manuscript, and the final recommendations were reviewed by the Clinical Practice Guidelines Committee.

Extensive surgery and lymphadenectomy do not improve survival in primary melanoma of the anorectum: results from analysis of a large database (SEER).

AIM: Primary anorectal melanoma is a rare disease with a dismal prognosis due to early distant metastasis. The prognostic value of positive loco-regional lymph nodes and the impact of lymphadenectomy on overall survival are unclear. We have investigated this by analysis of data obtained from a national representative database, controlling for potential confounders. METHODS: Data were retrieved from the Surveillance, Epidemiology and End Results (SEER) database. Multiple imputation analysis was performed to deal with missing data. Cox regression models were formulated using different prognostic factors including site of origin, gender, size, race, rate of lymph node metastasis (ratio between positive lymph node count and total lymph nodes harvested), extent of lymphadenectomy (none, level I etc.), age, type of surgery, stage of disease and administration of radiotherapy. RESULTS: Our population was composed of 208 patients who underwent surgery between 1998 and 2012. Rate of lymph node metastasis (P = 0.027; hazard ratio 1.873, 95% CI 1.076-3.261) and race (P = 0.019; hazard ratio 2.291, 95% CI 1.148-4.575) were found to be independent predictors of survival. CONCLUSION: Based on the data retrieved from the SEER database, metastasis to loco-regional lymph nodes is an important prognostic factor, but lymphadenectomy does not improve survival.

Propensity adjusted appraisal of the surgical strategy for appendiceal carcinoids.

BACKGROUND: The treatment algorithm for appendiceal carcinoids is based on tumor size. We wanted to verify whether right hemicolectomy confers a survival advantage compared with appendectomy in patients with tumors larger than 2 cm. METHODS: Data regarding patients with primary carcinoid tumors of the appendix were collected from the Surveillance, Epidemiology, and End Results program database. A propensity score with respect to surgical intervention was calculated with a binary logistic regression including gender, stage of disease, and age as covariates. The groups were matched with a 1:1 ratio, using the nearest neighbor algorithm. A Cox proportional hazards model adjusted for propensity score was implemented to assess the impact of surgical intervention on overall survival. RESULTS: Only stage of disease differed between the groups (p = 0.011). After matching, based on the propensity score, our series was constituted of 109 patients undergoing appendectomy and 109 undergoing right hemicolectomy. The type of surgical intervention failed to reach statistical significance. CONCLUSIONS: Right hemicolectomy did not seem to confer any survival advantage on patients with appendiceal carcinoids with a diameter >2 cm. For this reason, tumor size should not be considered an absolute indication for right hemicolectomy.

Sigmoid intramural hematoma and hemoperitoneum: an early severe complication after stapled hemorrhoidopexy.

Stapled hemorrhoidopexy is a widely used surgical technique for treating hemorrhoids, although severe complications have been reported. The authors report a rare case of extensive ascending intramural hematoma of the sigmoid colon complicating stapled hemorrhoidopexy, with perforation and hemoperitoneum. Diagnosis was established at CT scan and treatment consisted of drainage, suturing, and diverting colostomy. This reported case is the ninth described in the literature, but, so far, it is not known what preventive measures to use in order to avoid such a rare complication. Adoption of a correct surgical technique remains the step of utmost importance in order to prevent such a severe postoperative complication.

Long-term results of laparoscopic gastric sleeve: the importance of follow-up adherence.

OBJECTIVE: This study was conducted to assess the long-term results of the Laparoscopic Sleeve Gastrectomy (LSG) in patients not compliant with follow-up, and in patients who completed a postoperative follow-up program. PATIENTS AND METHODS: The data concerning LSG patients operated from February 2011 to December 2013 were retrospectively reviewed basing on a single center database. The patients with complete long-term follow-up were scheduled in Group A, while patients who failed to attend controls for more than two years were scheduled in Group B. Long-term results (weight loss, comorbidity improvement and late complications) were compared between the two groups. RESULTS: The study population consisted of 285 patients. Of these, 101 had a complete follow-up with a mean duration of 71 ± 7.6 months (Group A). The remaining 184 patients (Group B) were not compliant with follow-up and, consequently, the mean duration of follow-up was 5.5 ± 7.3 months (p < 0.00001). A higher number of patients with insufficient weight loss was recorded in Group B with respect to Group A (78 vs. 23; p = 0.001). The number of patients with results below 25% EWL was significantly higher in Group B than in Group A (24 vs. 5; p = 0.04). In the long-term, the rate of patients with symptomatic reflux requiring medical treatment was two-fold higher in Group B than in Group A. CONCLUSIONS: The adherence to a long-term follow-up plan after LSG seems to decrease the number of patients experiencing insufficient weight loss and those at risk for developing a gastro-esophageal reflux disease.

Management of hemorrhoidal disease: new generation of oral and topical treatments.

Hemorrhoidal disease is a widespread proctologic clinical entity. Even if surgical excision is an effective treatment, it only represents the standard procedure for patients with high-grade hemorrhoids. Considering that most cases are grade I or II hemorrhoids, oral or topical therapies are widely used despite, currently, there are no satisfactory options for these kinds of treatments. The pathology involves the degeneration of the supporting tissue of the anal cushions, causing venous dilation, blood stagnation, formation of edematous venous plexus covered by mucosa and inflammation. An effective treatment must, therefore, be multi-targeted and capable of acting on all the pathological mechanisms simultaneously. During the 8th National Congress of the Italian Association of Colorectal Surgery (SICCR), some clinical evidence of hemorrhoidal disease has been discussed along with new opportunities in oral and topical treatment options. Among these, the effectiveness and the safety of two innovative products, a sublingual nanoemulsion and a liquid bandage, has been reported.

Doppler-Guided Transanal Hemorrhoidal Dearterialization (DG-THD) Versus Stapled Hemorrhoidopexy (SH) in the Treatment of Third-Degree Hemorrhoids: Clinical Results at Short and Long-Term Follow-Up.

INTRODUCTION: The stapled hemorrhoidopexy (SH) and the Doppler-guided transanal hemorrhoidal dearterialization (DG-THD) are minimally invasive procedures for the surgical treatment of hemorrhoids. This study aims to verify the efficacy of the DG-THD versus the SH in the treatment of third-degree hemorrhoids. METHOD: One hundred consecutive patients were causally allocated to either procedure, obtaining two groups of 50 pts. A clinical examination was performed at 3, 7, 15, and 30 days after the operation. Quality of life, anal symptoms, recurrence of hemorrhoids, and reoperation were assessed by means of a questionnaire and of a clinical examination at long-term follow-up (7.0 year average). RESULTS: At short-term follow-up, the median postoperative pain score was significantly lower in DG-THD group compared to SH group, (V.A.S 2 vs 6; t = 2.65, p < 0.01). The morbidity rate and the return to normal life and work were similar after the two procedures. At long-term follow-up, the incidence of piles was not statistically different between the two groups (DG-THD 10.0 %; SH 14.0 %). No differences were reported by patients in terms of satisfaction for surgery. CONCLUSION: SH and DG-THD procedures do not show significantly different results with regard to the patients outcome. However, considering the lower p. o. pain, the DG-THD might be proposed as the first line treatment in third-degree hemorrhoids.

[Hyperthyroidism in the elderly]. / L'ipertiroidismo nell'anziano.

UNLABELLED: Hyperthyroidism in elderly patients is not to be under-evaluated, since it is characterized in such age range by particular clinical and prognostic features. Based upon literature survey and their clinical experience, the authors discuss in the present paper clinical, diagnostic and therapeutic problems of hyperthyroidism in geriatric patients. MATERIAL AND METHOD: In the period between 1978-2003 out of 1804 patients surgically treated for thyroid disease (non neoplastic in 1470 pts.), 180 subjects presented hyperthyroidism (17%). 36 were in geriatric age-range (mean age 76 yr.; 29 females and 7 males). 26 presented a Multinodular Toxic Goiter (72.2%), whereas 9 patients complained of Plummer Adenoma (25%); only 1 patient showed Basedow disease (2.7%). RESULTS: As far as ASA classification, there were 7 ASA I, 27 ASA II and 2 ASA III. Compression of digestive tract and/or respiratory airway represented a surgical indication in 15 patients (41.6%). 12 (33.4%) were operated due to predominant cardiac symptoms (tachycardia, atrial fibrillation). The remaining 9 patients (25%) were treated for the concomitance of atypical symptoms of hyperthyroidism. We performed 15 total thyroidectomy, 7 "near totally", 8 sub-total, 6 hemithyroidectomy in case of Plummer adenoma. Postoperative mortality was nihil; p.o. morbidity was 5.5% for medical conditions (pneumonia) and surgery-related (1 laryngeal recurrent paralysis and 1 hypoparathyroidism) in 5.5%. Post-operative follow-up, conducted at 6 and 12 months from the operation, showed regression of hyperthyroidism and regression or improvement of all clinical symptoms complained by the patient. CONCLUSION: Surgical treatment seems to be the only immediate and definitive cure for hyperthyroidism. Geriatric age does not seem to be a surgical contraindication.

Ketanserin, a new blocking agent of serotonin S2-receptors. Respiratory functional effects in chronic obstruction of the airways.

The role played by serotonin (5-HT) in the regulation of bronchomotor tone has up to now been a much debated question, although there is good evidence that it induces intense bronchoconstriction after inhalation in asthmatic patients. Serotonin has been found to contract the tracheobronchial smooth muscle of different animals. Some data suggest that tracheobronchial contraction due to serotonin is mediated by its interaction with the S2-receptor. The blockade of this receptor by ketanserin, a serotoninergic antagonist which primarily binds to S2-serotoninergic receptors, produces bronchodilation. The respiratory effects of intravenously administered ketanserin (10 mg) or placebo were compared in a double-blind crossover study in 14 patients with chronic obstruction of the airways. The forced expiratory volume in one second (FEV1) and the instantaneous forced expiratory flow after 50 percent of the forced vital capacity has been exhaled (FEF50%) did not change after placebo, but they increased significantly after administration of ketanserin. The results suggest that in patients with chronic obstructive pulmonary disease, serotonin may play a role in the development of obstruction of the airways, even if the mechanism remains undefined.

Bowel stricture due to ischemic colitis: report of three cases requiring surgery.

The diagnosis of ischemic colitis is challenging and still based upon a high index of suspicion. We report here, three patients affected by ischemic colitis causing stenosis and intestinal obstruction that required surgical treatment. Results of surgery in the three cases were not fair reflecting the high mortality and morbidity rate of ischemic colitis. However, the three cases showed peculiar features allowing us to make a few speculative considerations. Better results in the treatment of ischemic colitis might be achieved by means of a prompt recognition of the initial picture and through a better control of the many associated diseases, that represent the main risk factor for the development of ischemic colitis itself and for the bad prognosis of surgical treatment.

[Intestinal obstruction caused by ischemic colitis: description of 3 surgically treated cases]. / Occlusione intestinale da colite ischemica: descrizione di 3 casi trattati chirurgicamente.

[Risk indices in geriatric surgery: ASA index versus Reiss index]. / Indici di rischio in chirurgia geriatrica: indice ASA versus Indice Reiss.

The use of the Risk Index in surgery is aimed to plan surgical strategy in order to achieve a better postoperative prognosis. This is especially true in geriatric surgery where the ASA Index and, more recently, the Reiss Index are widely employed. Since the mentioned Risk Indices are calculated on the basis of different factors, in this study we compared the two Risk Indices with the aim of verifying which index offers better prognostic indications. 210 patients, aged over 70 years, undergoing surgical treatment, were investigated. The patients were grouped according to the ASA and Reiss Indices. The ASA Index showed good correlation only with postoperative mortality. The three classes of Reiss Index showed a significant correlation with the incidence of post-operative morbidity and mortality (p.o. morbidity: 7.1%, 21.5%, 30.3%; p.o. mortality; 1.7%, 9.2%, 24.2% -Chi 2 = 20.7; p < 0.001). Our results support the hypothesis that Reiss index offers better prognostic evaluation of postoperative outcome, suggesting its use in assessing postoperative prognosis in geriatric patients. In addition, our observation confirms the criticism reported of the ASA Index, merely considered as an indicator of health status regardless of surgical treatment. In conclusion, routine preoperative evaluation of the Reiss Index should be advised in geriatric patients with the aim to forecasting surgical risk in the first place, and them modifying operative strategy in order to improve postoperative results.

[The use of prosthetic meshes in the surgical treatment of inguinal hernia: the costs and profits for the local health screening unit]. / Utilizzazione delle reti protesiche nel trattamento chirurgico dell'ernia inguinale: costi e guadagni per la ULSS.

BACKGROUND: Inguinal hernioplasty represents one of the most frequently performed surgical operation. The recent introduction of prosthetic mesh made Bassini operation obsolete, with more space gained by the newly developed "tension-free" and "sutureless" surgical techniques. This new approach, however, results in increased initial costs for the hospital, due to the purchase of mesh materials. On the other hand a reduction of overall expenses for a single hernia repair should be expected. In this work an attempt is made to verify this, by calculating the cost-benefit ratio of different techniques for hernia repair. METHODS: The type and amount of materials used in a standard Bassini hernia repair, Lichtenstein and Trabucco have been examined. The amount of anesthetic drugs required, the average hospital stay and time away from work were recorded too. The costs of the three operations considered, not including routine expenses (operating room, bed sheet, etc.) have been estimated. RESULTS: Lichtenstein and Trabucco repair performed in local anesthesia (L. 1.354.120, L. 1.567.120) were cheaper than Bassini (L. 2.820.950). CONCLUSIONS: Since the system of diagnosis-related group offers a fixed amount of reimbursement for hernia repair (L. 3.247.000), the extensive use of tension free and sutureless methods, offers better profit for the Hospital. Last but not least, tension free hernia repair ensures short hospital stay, less postoperative pain, good compliance and better quality of life for the patient.
