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.

Optimal treatment duration of glyceryl trinitrate for chronic anal fissure: results of a prospective randomized multicenter trial.

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 < 0.05) and improvement of VAS score (P < 0.05) on both univariate and multivariate analysis. A lower baseline resting pressure was associated with better pain resolution on univariate analysis (P < 0.01). VAS at defecation and fissure healing significantly improved until 40 days (P < 0.001), while the difference between 40 and 80 days was not significant. CONCLUSION: We found no benefits in treating CAF with topical GTN for 80 days compared to 40 days. Fissure healing and VAS improvement continue until 6 weeks of treatment but are unlikely thereafter.

Combination therapy with symbiotics and local anti-inflammatories for red anusitis.

AIM: The aim of this study was to compare red anusitis treatment with topical mesalazine alone versus combined treatment with mesalazine plus a symbiotic (zir fos(R), Alfa Wassermann) to determine whether the effect of a therapy combining anti-inflammatory activity with a symbiotic that interferes with intestinal dysbiosis can improve anusitis symptoms. METHODS: From May 2004 to December 2005, 24 patients (14 male, 10 female; mean age 46.3 years, range 28-67) with idiopathic red anusitis, without other colo-proctologic diseases, were enrolled in a double blind study on the effect of topical mesalazine alone versus combined mesalazine plus symbiotic treatment. RESULTS: In the mesalazine monotherapy group, reduction in pain, hyperemia and bleeding was transient and symptoms recurred 1 year after discontinuation of treatment (mean visual analogue scale [VAS] scores: pain 3.1; hyperemia 2; bleeding 2.5. In the combined treatment group, a significant improvement in symptoms was noted (mean VAS scores: pain 1.5; hyperemia 0.5; bleeding 0) at 1 month after discontinuation of treatment. CONCLUSION: The results showed a greater long-term benefit of combination therapy mesalazine plus symbiotic (zir fos) in the treatment of red anusitis than with topical mesalazine alone, particularly for pain and bleeding. Further studies on larger series investigating additional subjective and objective variables are needed to confirm these findings.

Marsupialization of fistulotomy and fistulectomy wounds improves healing and decreases bleeding: a randomized controlled trial.

BACKGROUND: Marsupialization of anal fistulotomy/fistulectomy wound leaves less raw unepithelialized tissue. The suture results in a more rapid healing and is likely to reduce the risk of bleeding but at the cost of an increased pain and infection. The aim of this prospective study was to compare the outcomes of marsupialization and open wound. METHODS: Forty-six consecutive patients with anal fistulae were recruited in a randomized controlled trial. Fistula tracks were treated by fistulotomy and/or fistulectomy. The resulting wounds were marsupialized to the skin edges with locking continuous absorbable sutures (M group) or left open (O group). The clinical outcome was then evaluated. The intra-operative effect of the suture on wound size was recorded as well as the postoperative pain using a 0-10 visual analogue scale (VAS) and the occurrence of both wound bleeding and infection. RESULTS: Twenty-two patients were randomized to the M group and 24 to the O group. There were no differences in the age, sex and fistula type between the groups. Mean follow-up times were 10.5 and 13.8 months, respectively. No significant difference was observed in postoperative pain, the VAS being 3.5 +/- 1.5 in the M group and 3.4 +/- 1.6 in the O group at 12 h (mean +/- s.e.m.; n.s). The marsupialization nearly halved the size of the wound intra-operatively from an area of 1749 +/- 66 mm2 to 819 +/- 38 mm2 (P < 0.001), which subsequently decreased to 217 +/- 15 mm2 after 4 weeks (P < 0.01). No significant reduction of wound size was observed in the O group (from 1171 +/- 31 mm2 to 543 +/- 19; n.s). Bleeding occurred less frequently in M group than in O group (36%vs 46%, P < 0.05), whereas the difference in the postoperative sepsis rate was not significant, being 14% in M vs 21% in the O group. Three reinterventions were needed in both groups due to wound sepsis. CONCLUSION: Marsupialization after fistulotomy/fistulectomy significantly reduces the size of the wound and the risk of bleeding, without increasing postoperative pain and sepsis.

[Tension-free laparoscopic versus open inguinal hernia repair]. / Ernioplastica laparoscopica versus ernioplastica laparotomica nel trattamento delle ernie inguinali primitive.

AIM: During the last decade laparoscopic techniques have been applied to the treatment of inguinal hernia to combine tension-free technique, esthetic, and functional benefits of mini-invasive surgery. Anyway controversy persists regarding the most effective inguinal hernia repair. The aim of this study is to compare the open technique and the laparoscopic approach concerning: complications, recurrences, recovery time and return to usual activity. METHODS: A randomized prospective analysis of 121 consecutive inguinal hernia repairs was performed over a 12-month period. Male well-informed patients with primary monolateral inguinal hernia (ASA I-II) were divided into 2 groups and consecutively treated; group A was treated with laparoscopic transabdominal preperitoneal approach (TAPP) (median age 47+/-7 years, 57 patients), group B with open mesh herniorrhaphy (45+/-6 years, 64 patients). RESULTS: Complication rate was 5.26% for group A (none needed conversion) and 4.68% for group B. All complications were considered minor. No recurrences were observed over a 12-month follow-up in both groups. Post-operative hospital stay and return to activity show statistically significant differences. Median post-hospital stay was 1.7 days for group A while it was longer (2.9 days) for group B. Significant difference was observed in the duration of convalescence too (group A 9.3+/-7.2 days; group B 12.1+/-7. 1 days). CONCLUSION: On the basis of our experience, even if a longer follow-up is needed, the validity of laparoscopic approach to inguinal hernia is confirmed. General anesthesia and higher costs are reasonable compromises for a shorter period of discomfort in patients with a low ASA index and busy job/sport activity.

[Chromoendoscopy in the diagnosis of precancerous lesions of the esophagus. Our experience]. / La cromoendoscopia nella diagnostica delle lesioni precancerose dell'esofago. Nostra esperienza.

The elements of an unfavourable prognosis for oesophageal cancer are frequent metastasis, high incidence of local recurrence and mainly the difficulty of an early diagnosis. Alcohol, tobacco and precancerous lesions are the most important risk factors of these tumours. According to literature, the authors suggest the method of chromoendoscopy, with vital staining by lugol or blue toluidine for endoscopic; guidance to biopsy in the aimed screening of patients, whose habits--alcohol, smoking--should cause, in time, the rising of lesions with neoplastic potentiality. Endoscopy with bioptic test is the best diagnostic investigation. In fact sensibility and specificity of these investigations increase using this method with vital staining.

Recombinant bactericidal/permeability-increasing protein (rBPI21) as adjunctive treatment for children with severe meningococcal sepsis: a randomised trial. rBPI21 Meningococcal Sepsis Study Group.

BACKGROUND: Endotoxin is a primary trigger of the inflammatory processes that lead to shock, multiorgan failure, and purpura fulminans in meningococcal sepsis. Bactericidal/permeability-increasing protein (BPI) is a natural protein, stored within the neutrophil granules, that binds to and neutralises the effects of endotoxin in vitro, in laboratory animals, and in humans. To establish whether a recombinant 21-kDa modified fragment of human BPI (rBPI21), containing the active antimicrobial and endotoxin-neutralising moiety, would decrease death and long-term disability from meningococcal sepsis, we did a randomised, double-blind, placebo-controlled trial of rBPI21 in children with severe meningococcal sepsis. METHODS: We enrolled children (2 weeks to 18 years of age) presenting to 22 centres in the UK and the USA with a clinical picture suggestive of meningococcal sepsis, and with evidence of severe disease. Children were randomly assigned rBPI21 (2 mg/kg over 30 min followed by 2 mg/kg over 24 h) or placebo (0.2 mg/mL human albumin solution) in addition to conventional medical therapy. Primary outcome variables were mortality, amputations, and change in paediatric overall performance category (POPC) from before illness to day 60. Analysis was by intention to treat. FINDINGS: Of 1287 patients screened, 892 were excluded, including 57 patients who died or who met criteria for imminent death before receiving the study drug. 190 patients received rBPI21, and 203 placebo. 34 (8.7%) of 393 patients died during the study: 14 (7.4%) in the rBPI21 group and 20 (9.9%) in the placebo group (odds ratio 1.31 [95% CI 0.62-2.74], p=0.48). Compared with patients randomised to placebo, fewer patients treated with rBPI21 had multiple severe amputations (six of 190 [3.2%] vs 15 of 203 [7.4%], odds ratio 2.47 [0.94-6.51], p=0.067), and more had a functional outcome similar to that before illness (as measured by the POPC scale) at day 60 (136 of 176 [77.3%] vs 126 of 190 [66.3%], p=0.019). INTERPRETATION: Because most deaths occurred in the interval between identification of patients and study drug administration, the mortality rate in the placebo group was substantially lower than predicted. The trial was therefore underpowered to detect significant differences in mortality. However, patients receiving rBPI21 had a trend towards improved outcome in all primary outcome variables. Given the excellent severity match between placebo and rBPI21 groups at study entry, the results overall indicate that rBPI21 is beneficial in decreasing complications of meningococcal disease.

[Post-traumatic diaphragmatic hernia with late diagnosis. Report of a clinical case]. / Ernia diaframmatica post-traumatica a diagnosi tardiva. Descrizione di un caso clinico.

Starting from the observation of a case of late diagnosed left-side hernia after traumatic rupture of diaphragma, the authors consider the increasing incidence of this pathology during the years. The increased frequency of thoraco-abdominal traumas and the more sophisticated diagnostic tools, permit an earlier diagnosis nowadays. In our patient the diagnosis was made late on the basis of the standard x-ray of the thorax. The CT scan of the thorax and of the abdomen gave more informations. Left thoracotomy enabled a wide exposure of the herniated viscera; the breakthrough of the diaphragm was repaired by means of interrupted suture and it was necessary to apply two prostheses of synthetic material.

[Rare primary localization of echinococcus cysts. Presentation of 2 cases and review of the literature]. / Le cisti da echinococco primitive a localizzazione rara. Presentazione di due casi e revisione della letteratura.

Hydatidosis is a parasitic disease. It's generally localized in the liver and in the lung even if any other organ can be potentially affected. From 92 to 98 our group observed two cases of rare primitive localisation of echinococcosis (one mediastinal and one retroperitoneal cyst). The patients performed serologic and instrumental exams to establish the right therapeutic strategy. Both of them were operated (it was carried out a pericystectomy with open cyst in one of them and an exeresis of the right adrenal gland including hydatid cyst in the other one). A patient underwent to Albendazole prophylaxis. During the follow-up the patients performed echography, CT and MRI. Considering the literature's data and their experience the authors emphasize: 1. The diagnosis of rare primitive localization of hydatidosis is very difficult. 2. The diagnostic iter requires a correct relationship between the laboratory and imaging data. 3. Only the exclusion of other localizations of the cyst (liver, lung or other organs) give us the possibility to diagnose a rare primitive localization of hydatidosis. 4. The treatment of hydatidosis is specifically surgical. 5. The surgeon can use several different approaches in relationship to the place and the anatomopathologic characters of the cyst.
