Spontaneous bilateral quadriceps tendon rupture treated with polyethylene terephthalate tape augmentation: Report of two consecutive cases.

Spontaneous rupture of quadriceps tendon (QT) is a rare condition and it is commonly associated with systemic comorbidities and medical products assumption, which may lead to tendon degeneration. While unilateral rupture is a quite common injury, spontaneous bilateral ruptures are very rare. Herein, we report two consecutive cases of spontaneous bilateral QT rupture in two patients with a positive history of chronic statin use, successfully treated with bilateral single-stage reconstruction with polyethylene-terephthalate tape augmentation. At 12 months of follow-up, both patients recovered the full extension, a 120° pain-free flexion and knee scores improvement. Magnetic resonance imaging at one year showed a complete, bilateral, bio-integration of the augmentation for each knee. In conclusion, polyethylene terephthalate tape augmentation provides a good structural support with a good grade of bio-integration, allowing a fast recovery.

The Impact of Hemodialysis on Mortality and Personal Independence After Hip Fracture. A Prospective Matched Cohort Study.

OBJECTIVE: To determine the cumulative 30-day and 1-year mortality as well as personal independence after hip fracture in patients on hemodialysis. DESIGN: Prospective, observational cohort study with matched controls. SETTING: One teaching hospital, one metropolitan trauma center, one peripheral hospital. PATIENTS AND INTERVENTION: Study group: a consecutive cohort of 64 patients with end-stage renal disease receiving chronic hemodialysis who had undergone surgery for a trochanteric or femoral neck fracture from June 2008 to November 2016. CONTROL GROUP: subjects without end-stage renal disease who underwent surgery for similar hip fractures. MAIN OUTCOME MEASURE: One-year mortality, activities of daily living, and ambulatory activity. RESULTS: The 30-day and 1-year mortality rate in patients with a hip fracture undergoing hemodialysis was 25.0% and 57.8%, respectively. Hemodialysis was independently associated with increased 30-day (Hazard ratio 2.933; 95% confidence interval 1.270-6.770; P = 0.018) and 1-year (hazard ratio 2.535; 95% confidence interval, 1.494-4.299; P < 0.001) mortality compared with the matched controls. At the 1-year follow-up, loss of personal independence in comparison with the prefracture status was detected. CONCLUSIONS: Hemodialysis was associated with increased mortality after hip fracture. A worse prefracture functional status predicted the loss of functional independence at follow-up. LEVEL OF EVIDENCE: Prognostic Level III.

Chronic constipation diagnosis and treatment evaluation: the "CHRO.CO.DI.T.E." study.

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.

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.

The effectiveness of current acute variceal bleed treatments in unselected cirrhotic patients: refining short-term prognosis and risk factors.

OBJECTIVES: The mortality from esophageal variceal hemorrhage in liver cirrhosis patients remains approximately 15-20%. Predictors of short-term outcomes, such as the hepatic venous pressure gradient, are often unavailable in the acute setting. Clinical variables seem to have a similar predictive performance, but some variables including active bleeding during endoscopy have not been reevaluated after the utilization of endoscopic banding as endoscopic procedure. In addition, patients with severe liver failure are often excluded from clinical trials. The aim of this study was to prospectively reevaluate the risk factors affecting a 5-day failure after acute variceal bleeding in unselected cirrhotic patients, managed with the current standard treatment using vasoactive drugs, band ligation, and antibiotics. METHODS: One hundred and eighty five patients with liver cirrhosis and variceal bleeding admitted from January 2010 to July 2011 were evaluated. RESULTS: Hepatocellular carcinoma was present in 28.1% of cases and portal vein thrombosis (PVT) was present in 17.3% of cases. Band ligation was feasible in 92.4% of cases. Five-day failure occurred in 16.8% of cases; 12 patients (6.5%) experienced failure to control bleeding or early rebleeding, and 66.7% of patients died within 5 days. The overall 5-day mortality rate was 14.6%. By multivariate analysis, we determined that Child-Pugh class C, a white blood cell count over 10 × 10(9)/l, and the presence of PVT were the only independent predictors of the 5-day failure. CONCLUSIONS: The prognosis of a consistent group of liver cirrhosis patients with variceal bleeding remains poor. The current treatment is highly effective in controlling variceal bleeding, but mortality is related mainly to the severity of liver failure.

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.

The daily diary and the questionnaire are not equivalent for the evaluation of bowel habits.

BACKGROUND: It is unclear whether questionnaires and diary cards, which are widely used to collect data on bowel habits, provide analogous information. AIMS: We verified the concordance between the data provided by a daily diary and a retrospective questionnaire. METHODS: A 4-week diary (DIARY) concerning bowel habits was compiled by 221 subjects. They were also asked to fill out a questionnaire on their bowel habits before (BEF) and after (AFT) the diary period. RESULTS: Concerning bowel movements, no significant difference was detected in the concordance between BEF and DIARY (rho: 0.80), AFT and DIARY (rho: 0.84), or BEF and AFT (rho: 0.84). The mean concordance in the other defecation-related parameters between BEF and DIARY (K: 0.62) and between DIARY and AFT (K: 0.63) were both significantly lower than that seen between BEF and AFT (K: 0.80; p<0.01). CONCLUSION: A considerable discrepancy between the two methods of assessment was found. The higher concordance between BEF and AFT than between DIARY and AFT regarding defecation-related parameters suggests that when a subject recalls events, even those from the recent past, he/she tends to generalize, reporting more or less the same data for different periods of time. These two instruments cannot be viewed as interchangeable, and their inherent differences must be taken into account when deciding which one to employ in different settings.

Platelet gel supplementation in long bone nonunions treated by external fixation.

OBJECTIVE: The aim of the present study was to evaluate the use of previously frozen, thawed platelet gel supplementation to accelerate the healing of long bone nonunions treated by external fixation. DESIGN: Prospective case series with historical controls. SETTING: University Hospital. PATIENTS: Twenty patients affected by tibial, humeral, or forearm atrophic nonunions were treated by percutaneous stabilization with unilateral external fixators and injection of autologous platelet gel. The healing time was compared to the result obtained in a historical control group treated without platelet gel supplementation. MAIN OUTCOME MEASUREMENTS: Consolidation rate and radiographic healing time of nonunions in the 2 groups were assessed by independent blinded observers. The nonunion was judged to be healed when bridging callus formation on both radiographic views was observed on at least 3 of 4 cortices. RESULTS: The healing rate of nonunion was 90% (18/20) in platelet gel cases and 85% (17/20) in controls, respectively (P = 0.633). The mean time until radiographic consolidation in nonunions supplemented with platelet gel (147 +/- 63 days) was not different to the result in the control group (153 +/- 61 days; P = 0.784). Analyzing the mean healing time for separate segments, no differences were noted between study and control group-that is, tibia: 112 +/- 43 and 130 +/- 5 days, respectively (P = 0.382); humerus, 225 +/- 36 and 202 +/- 70 days, respectively (P = 0.530). CONCLUSION: The present study failed to show the clinical usefulness of isolated percutaneous platelet gel supplementation in long bone nonunions treated by external fixation; however, caution should be exercised in interpreting this result because the actual numbers are small and the statistical power is limited.

The corner of the coloproctologist: what to ask to radiologist.

Defecation disorders, fecal incontinence, often associated to urinary and genital dysfunction, represent symptoms of a large number of functional and structural alterations of pelvic floor. They can be evaluated by functional and morphologic tests. A perfect anatomic and functional knowledge of the anorectum and pelvic floor is indispensable for a correct diagnostic and therapeutic path. Incontinence due to sphincter lesions can be diagnosed only by imaging techniques. In defecation disorders the issue is complex because functional and anatomic alterations can coexist. The radiological diagnosis of dyssynergic defecation is a diagnosis of confidence that enhances its value when manometric and electromyographic evidence of pelvic dyssynergia are detected. When anatomical alterations are detected the aim is to understand their physiopathology, to make a more precise diagnosis and treatment, and to minimize the errors of an inappropriate therapy. Our attention is focused on the information provided by imaging techniques about anorectum and pelvic floor abnormalities for optimal therapeutic planning.

An extended assessment of bowel habits in a general population.

AIM: Bowel habits are difficult to study, and most data on defecatory behaviour in the general population have been obtained on the basis of recalled interview. The objective assessment of this physiological function and its pathological aspects continues to pose a difficult challenge. The aim of this prospective study was to objectively assess the bowel habits and related aspects in a large sample drawn from the general population. METHODS: Over a two-month period 488 subjects were prospectively recruited from the general population and asked to compile a daily diary on their bowel habits and associated signs and symptoms (the latter according to Rome II criteria). A total of 298 (61%) participants returned a correctly compiled record, so that data for more than 8 000 patient-days were available for statistical analysis. RESULTS: The average defecatory frequency was once per day (range of 0.25-3.25) and was similar between males and females. However, higher frequencies of straining at stool (P=0.001), a feeling of incomplete emptying and/or difficult evacuation (P=0.0001), and manual manoeuvres to facilitate defecation (P=0.046) were reported by females as compared to males. CONCLUSION: This study represents one of the first attempts to objectively and prospectively assess bowel habits in a sample of the general population over a relatively long period of time. The variables we analyzed are coherent with the criteria commonly used for the clinical assessment of functional constipation, and can provide a useful adjunct for a better evaluation of constipated patients.

Topical nifedipine with lidocaine ointment vs. active control for treatment of chronic anal fissure: results of a prospective, randomized, double-blind study.

PURPOSE: Chronic anal fissure may be treated by chemical or surgical sphincterotomy. The aim of this study was to test the efficacy of local application of nifedipine and lidocaine ointment in healing chronic anal fissure. METHODS: The study was performed according to a prospective, randomized, double-blind design. One hundred ten patients who gave informed consent were recruited. They received a clinical examination, a questionnaire to evaluate symptoms and pain, anorectal manometry, and anoscopy. Healing of anal fissure at Day 42 of therapy was defined as the primary efficacy variable of the study. Patients treated with nifedipine (n = 55) used topical 0.3 percent nifedipine and 1.5 percent lidocaine ointment every 12 hours for 6 weeks. The control group (n = 55) received topical 1.5 percent lidocaine and 1 percent hydrocortisone acetate ointment during therapy. Anal pressures were measured by recording resting and maximal voluntary contraction pressures at baseline and at Day 21. Long-term outcomes were determined after a median follow-up of 18 months. RESULTS: Healing of chronic anal fissure was achieved after 6 weeks of therapy in 94.5 percent of the nifedipine-treated patients (P < 0.001) as opposed to 16.4 percent of the controls. Mean anal resting pressure decreased from a mean value +/- standard deviation of 47.2 +/- 14.6 to 42 +/- 12.4 mmHg in the nifedipine group. This represents a mean reduction of 11 percent (P = 0.002). Changes of maximal voluntary contraction in nifedipine-treated patients were not significant. No changes in mean anal resting pressure and maximal voluntary contraction were observed in the control group. We did not observe any systemic side effect in patients treated with nifedipine. After the blinding was removed, recurrence of the fissure was observed in 3 of 52 patients in the nifedipine group within 1 year of treatment, and 2 of these patients healed with an additional course of topical nifedipine and lidocaine ointment. CONCLUSIONS: Our study clearly demonstrates that the therapeutic use of topical nifedipine and lidocaine ointment should be extended to the conservative treatment of chronic anal fissure.
