Surgical management of haemorrhoids: an Italian survey of over 32 000 patients over 17 years.

AIM: The management of haemorrhoids has changed significantly in the last two decades as a result of new insights into their pathophysiology and the availability of new surgical devices. The aim of this survey was to evaluate changes in the management of haemorrhoids in Italy over the last 17 years. METHOD: An electronic database which recorded details of management relating to the severity of haemorrhoids between 2000 and 2016 was obtained from 18 of 34 colorectal surgeons who were invited to participate. RESULTS: A total of 32 458 patients were treated for haemorrhoids by 18 expert coloproctologists during a 17-year period. Patients were classified as Grade II (7542, 23.2%), Grade III(15 360, 47.3%) and Grade IV (9556, 29.4%). Grade II haemorrhoids were treated with rubber band ligation in over 90% of the cases, and patients with Grade IV had a Milligan-Morgan (MM) haemorrhoidectomy in over 90% of the cases. In Grade III, the use of stapled haemorrhoidopexy progressively decreased from 30% to 35% (between 2000 and 2007) to 5% of the cases. Meanwhile, commencing from 2006 the use of Doppler-guided haemorrhoid artery ligation (DGHAL) with mucopexy increased progressively from 6% to 24%. Over the years, the percentage of MM haemorrhoidectomy remained consistent at between 65% and 70% of the cases. CONCLUSION: Relevant changes in the surgical choice of haemorrhoid treatment have occurred in Italy over the last 17 years. MM haemorrhoidectomy remains the most frequently performed procedure for Grade III haemorrhoids. Stapled haemorrhoidopexy has become much less popular in contrast to DGHAL with mucopexy which is being performed much more frequently.

Does a more extensive mucosal excision prevent haemorrhoidal recurrence after stapled haemorrhoidopexy? Long-term outcome of a randomized controlled trial.

AIM: The study aimed in a multicentric randomized controlled trial to define the role of a more extensive mucosal resection on recurrence of mucosal prolapse in patients with Stage III haemorrhoids undergoing stapled haemorrhoidopexy. METHOD: In all, 135 patients were randomized to treatment with a PPH-01/03 (Ethicon EndoSurgery) or an EEA (Covidien) stapler. They were reviewed after a minimum follow-up of 4 years to determine the rate of recurrent mucosal prolapse and general condition (wellness evaluation score). Postoperative bowel dysfunction was assessed using the Rome III criteria. RESULTS: Eighty-seven (65%) of the 135 patients (48 in the EEA stapler group and 37 in the PPH group) were available for long-term follow-up. The two groups were comparable for age, gender and duration of follow-up (mean 49.3 ± 5.4 months and 49.0 ± 5.3 months respectively). In the EEA group, 11 (23%) patients had some degree of recurrent prolapse compared with 12 (32%) in the PPH group (P = 0.409). Persistence of anal bleeding was significantly higher in the PPH group (P = 0.04) while the postoperative Haemorrhoid Symptom Score was significantly better in the EEA group (1.73 ± 1.65 vs 3.17 ± 1.94, P < 0.001). The wellness evaluation score was significantly better in the EEA group (1.2 ± 1.27 vs 0.6 ± 1.0, P = 0.028). Furthermore, 7 (15%) of the patients in the EEA group complained of some evacuation disturbance compared with 13 (36%) in the PPH group (P = 0.021). CONCLUSION: The study failed to demonstrate any significant difference in the long-term recurrence rate of Stage III haemorrhoids using EEA or PPH. Nevertheless, use of the larger volume EEA provides better symptom resolution compared with PPH.

Flavonoids mixture (diosmin, troxerutin, hesperidin) in the treatment of acute hemorrhoidal disease: a prospective, randomized, triple-blind, controlled trial.

BACKGROUND: The role of a mixture of phlebotonics in the treatment of acute hemorrhoid crisis is investigated to test their efficacy. METHODS: One hundred and thirty-four consecutive patients with an acute hemorrhoidal crisis recruited in five colorectal units entered the study. Sixty-six of them were randomized to receive a mixture of diosmin, troxerutin and hesperidin (group A), and 68 a placebo (group B). The main symptoms, the use of oral painkillers and the Bristol scale score were recorded at each scheduled visit and compared using both Student's t test for independent samples and the ANOVA models for repeated measures. The presence of edema, prolapse and thrombosis were also recorded and compared using the Chi-square test. Furthermore, the trend of proportions during the time of the evaluations was assessed by the Chi-square test for linear trend. RESULTS: Pain, bleeding and the proportion of patients who reported persistence of edema and thrombosis decreased significantly after 12 days of treatment in group A. After 6 days, the number of paracetamol tablets taken by patients in group A was significantly lower than the amount of flavonoid mixture. CONCLUSIONS: The use of a mixture of diosmin, troxerutin and hesperidin is a safe and effective mean of managing symptoms of acute hemorrhoidal disease. Furthermore, in patients receiving treatment, there was faster control and lower persistence of edema and thrombosis.

Prospective multicenter observational trial on the safety and efficacy of LEVORAG® Emulgel in the treatment of acute and chronic anal fissure.

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 < 0.001. Pain and resting anal pressure decreased significantly after treatment. CONCLUSIONS: Treatment with THD Levorag(®) Emulgel proved to be effective for the reepithelization of AF and the reduction of pain in the short term in about 80 % of patients.

Control of post-hemorrhoidectomy symptoms and wound healing by Triclosan: a randomized, double-blind, controlled trial.

AIM: Milligan-Morgan hemorrhoidectomy (MM) is still the most common treatment for grades III and IV hemorrhoids despite prolonged post-operative anal pain and wound healing. This multicenter, double blind, randomized, controlled trial was designed to assess the safety and the efficacy of anal wound cleansing with Triclosan (Proctocid®) in the control of symptoms and healing time after MM. METHODS: A total of 113 patients with grades III and IV hemorrhoids, undergoing open hemorroidectomy by diathermy or Ligasure vessel sealing device, were randomly assigned to Triclosan or sodium hypochlorite solution. All patients received analgesics and a fiber-rich diet after hemorrhoidectomy. Postoperative anal pain, bleeding and/or secretion and itch were assessed 7, 14 and 21 days after hemorrhoidectomy by a Visual Analogue Scale (VAS) and the day of complete re-epithelialization of anal wounds was recorded. RESULTS: Fifty-five patients were randomized for Triclosan treatment and 58 for the control drug. The two groups were comparable for demographics, severity of hemorrhoids and technique used for the hemorrhoidectomy. The comparison of days to get complete anal wound healing shows a trend of significance (P=0.05) for the Triclosan group. Bleeding and/or secretion, anal pain and itch were significantly better (P=0.003; P<0.0001 and P=0.01, respectively). CONCLUSION: Triclosan solution for the treatment of post-hemorrhoidectomy wounds is safe and improves the control of post-operative symptoms and wound healing time compared to sodium hypochlorite.

Safety and short-term effectiveness of EEA stapler vs PPH stapler in the treatment of degree III haemorrhoids: prospective randomized controlled trial.

AIM: Stapled haemorrhoidopexy has gained wide acceptance due to less postoperative pain although postoperative bleeding and prolapse recurrence are among the major drawbacks of this technique compared with the standard Milligan-Morgan hemorrhoidectomy. The aim was to investigate a new stapler device designed to overcome these side effects. METHOD: In all, 135 patients (71 men, mean age 42 years) with degree III haemorrhoids were randomly allotted to stapled haemorrhoidopexy with PPH® staplers (Ethicon EndoSurgery) (63 patients) or with an EEA® stapler (Covidien) (72 patients) in four referral colorectal centres. The number of haemostatic overstitches apposed on the stapled suture, the area of the resected mucosa (in square centimetres) and any postoperative bleeding within 30 days were recorded. RESULTS: The mean area of the resected mucosa was significantly wider in EEA than PPH patients (35.75 ± 17.51 vs 28.05 ± 10.23 cm(2), P = 0.002). The median number of haemostatic stitches apposed in the EEA group was significantly lower than in the PPH groups (median value 1, vs 3, interquartile range 0-2, vs 2-5, P < 0.0001). Intraoperative haemostasis was better in the EEA group compared with the PPH01 and PPH03 groups. Postoperative bleeding occurred only in two PPH patients. CONCLUSION: Data suggest that the EEA stapler has better haemostatic properties than the PPH stapler and allows resection of a larger area of mucosal prolapse with potential benefits over the recurrence rate of haemorrhoid prolapse.

Ligasure Precise vs. conventional diathermy for Milligan-Morgan hemorrhoidectomy: a prospective, randomized, multicenter trial.

PURPOSE: Milligan-Morgan hemorrhoidectomy using radiofrequency dissection (Ligasure) has been proposed instead of conventional diathermy in view of its potential benefits in terms of postoperative anal pain and better hemostatic control, but the medical literature is still controversial. This multicenter, randomized, controlled trial was designed to compare the outcomes between Ligasure and conventional diathermy hemorrhoidectomy in the Milligan-Morgan procedures in a sufficient number of patients. METHODS: Patients with Grades III and IV hemorrhoids were randomized to two groups: Ligasure hemorrhoidectomy and conventional diathermy. Postoperative anal pain was measured by the Visual Analog Scale (VAS) and the analgesia required. Postoperative complications, wound healing, and return to working activities also were evaluated as secondary outcomes. RESULTS: A total of 273 patients, well matched for age, gender, working activity and grade of hemorrhoids, were randomized to two groups: Ligasure 146, and diathermy 127. The severity of postoperative anal pain was significantly less in the Ligasure group when measured at least 12 hours after defecation (P < 0.01), whereas it was similar at the time of defecation. The Ligasure group had significantly lower requirements for painkiller pills. There were no significant differences in early and late complications. Return to work and normal activities was significantly faster in the Ligasure group. CONCLUSION: Ligasure hemorrhoidectomy is an effective procedure for Grades III and IV hemorrhoids and facilitates a faster return to work and normal activities by reducing postoperative pain.

[186Re]HEDP in the palliation of painful bone metastases from cancers other than prostate and breast.

AIM: Palliative therapy using [186Re]hydroxyethylidene diphosphonate (HEDP) has been widely tested in patients with bone metastases from prostate and breast cancers. Whereas, to the best of our knowledge, only few cases of bone metastases from tumors other than prostate and breast treated with [186Re]HEDP have been reported. The aim of this paper is to report our experience with 186Re-HEDP in the palliation of painful bone metastases from tumors other than prostate and breast. METHODS: In this study 41 patients (17 non-small cell lung cancer-NSCLC, 1 small cell lung cancer, 1 lung neuroendocrine tumor, 8 bladder cancer, 3 kidney cancer, 3 gastric cancer, 1 uterine carcinoma, 1 colon cancer, 1 rhinopharynx carcinoma, 1 medullary thyroid carcinoma, 1 ovarian cancer, 1 esophagus cancer, 2 carcinoma of unknown origin) are evaluated. All patients had lesions with increased [99mTc]MDP uptake and none had radiological findings of mainly osteolytic lesions. A total of 46 therapeutic cycles were performed using a [186Re]HEDP activity of 1 295 MBq for each administration. After treatment, patients were followed up for 3 months or to the time of pain recurrence (if longer than 3 months). Responses were evaluated using a validated method considering the modifications of pain index, analgesic intake and performance status. RESULTS: Treatment efficacy was complete in 49% (20/41) of patients, partial in 36% (15/41) and negative in 15% (6/41). Namely, we observed 35% (6/17) complete, 41% (7/17) partial and 24% (4/17) negative responses in patients with NSCLC and 63% (5/8) complete, 25% (2/8) partial and 12% (1/8) negative responses in patients affected by bladder cancer. The median duration of pain relief in responder patients was 10 weeks. A mild platelet toxicity occurred in 32% (13/41) of patients. CONCLUSIONS: Pain palliation with [186Re]HEDP seems highly effective and safe also in patients with bone metastases from cancers other than prostate and breast. Patients who can benefit from the treatment with [186Re]HEDP can be selected on the basis of [99mTc]MDP bone scan and radiological examination findings.

Investigation of brain tumours with (99m)Tc-MIBI SPET.

The aim of this paper is to give the reader an updated overview of (99m)Tc-MIBI SPET applications in investigating brain tumours. Elements determining MIBI uptake at the level of the brain are first mentioned. (99m)Tc-MIBI SPET features in different malignant and benign brain lesions (low and high grade gliomas, glioblastoma multiforme, metastasis, lymphoma, meningioma, neuroma, radiation necrosis and other rarer brain lesions) are reviewed. The ability of 99mTc-MIBI SPET, alone or in combination with other radiotracers, in the differential diagnosis of brain lesions is discussed. We outline (99m)Tc-MIBI SPET value in determining brain tumours grading and in distinguishing tumour recurrence from radiation necrosis. Clinical applications of 99mTc-MIBI in the management of AIDS patients, where discrimination between lymphoma and several different lesions only on the basis of CT or MRI findings is often impossible, are reported. In addition the relationships among (99m)Tc-MIBI SPET, P-glycoprotein (MDR-1 gene product) expression in brain neoplasms and chemotherapy response are mentioned.

[Combined diagnosis in breast carcinoma: preoperative role of mammoscintigraphy with Tc99m-sestamibi. Our Experience]. / Diagnostica integrata nel carcinoma della mammella: il ruolo prechirurgico della mammoscintigrafia con Tc 99m-sestamibi. Nostra esperienza.

The Authors, taking recent literature on tumoral pathology breast studies in to consideration, studied a group of patients with a node or a suspect adenous zone by clinical and instrumental examination with mammoscintigraphy. 22 patients were selected by clinical examination, mammography and ultrasonography. A mammoscintigraphy (Tc 99m Sestamibi) was performed before the surgical operation. The histologic examination revealed 14 cases of breast cancer; 12 of these (86%) resulted positive after scintigraphy, while 2 were false negative. In this study, the scintigraphic exam and its diagnostic accuracy were analyzed, both in relation to anatomical structure of the mammary gland (thick breast, fibrocystic mastopathy, postsurgical scars, etc.) and also in relation to characteristics of the suspected node, the nature of which was not possible to determine from other exams carried out. In conclusion, after comparison between our experience and those reported in literature, we conclude that because of its high specificity and sensibility the mammoscintigraphy exam assumes an important comparative index in obtaining elements for an additional evaluation when other instrumental examinations are dubious.

[Emergencies in oncologic surgery of the large intestine]. / Le urgenze nella chirurgia oncologica del grosso intestino.

The authors analyse of the large intestine at their Institute over the past 20 years. Four hundred and fifty-two cases out of 842 were performed during the period 1970-1979 and 300 during the subsequent decade. 21% (95 cases) were emergencies during the first decade and 16% (62 cases) during the second. From this study it emerges that patients operated with primary resection during the first decade 1970-1979 had a better survival rate than those operated in various stages. This was particularly true of cases of occlusion, whereas in cases of perforation the percentage remained practically unchanged. The approach adopted for this type of pathology changed during the next decade and it was decided to opt for primary resective surgery. A comparison between emergency surgery performed in a single session and operations performed in a number of stages revealed that both survival and morbidity were improved in primary resective surgery, 20% and 10% respectively, whereas mortality was higher (15%).

[Follow up in carcinoma of the large intestine]. / Il follow-up nel carcinoma del grosso intestino.

A valid program of follow-up has always been a crucial point in the overall therapy of the colon-cancer. In this retrospective study, the authors have used as specimen 74 patients put under observation between the years 1987 and 1992. The patient have been followed throughout the diagnostic period with various methods. It has been the will of the authors, who have presented their protocol of reference, to put under comparison the various controlling methods in order to visualize their reliability, specificity and the indication of each one of them. The CEA is the most sensible haemanalysis for lifting the doubt of recidivation. As for the TAC and ultrasound it has been reserved the job of formulating a correct diagnosis; the results of both diagnostics through imagery have been more or less the same. However, the ultrasound examination have shown more false positives than the TAC. The research of the blood occult in the stool is a rapid and economic detection in the case of intramural recidivations, even if we cannot disregard the share of false positives. A high specificity for the study of intramural recidivations has been offered by the endoscopic scan particularly when associated by a brushing and biopsy.

[Risk factors in laparoscopic cholecystectomy]. / I fattori di rischio nella colecistectomia laparoscopica.

In this report the authors have analysed the various risk factors of the laparoscopy cholecystectomy, proving that those are not different from the ones of standard open cholecystectomy. It has been underlined that laparoscopy cholecystectomy offers significant advantages over open cholecystectomy and moreover the possibility to convert laparoscopy cholecystectomy when it is necessary.

[The effect of Lactobacillus acidophilus and Bifidobacterium bifidum on the intestinal ecosystem of the elderly patient]. / Lactobacillus acidophilus e Bifidobacterium bifidum sull'ecosistema intestinale dell'anziano.

The authors have tested the therapeutic efficacy of a multibacterial combination consisting of Lactobacillus acidophilus (10(9)) and Bifidobacterium bifidum (10(9)) in elderly patients with bowel disorders. Bacteriological and histopathologic investigation showed this combination to yield excellent biologic results with restoration of duodenal bacterial flora and subsidence of clinical symptoms. The function of the muciparous glands was restored and the duodenal mucosa was normalized.
