Early rehabilitation reduces the onset of complications in the upper limb following breast cancer surgery.

BACKGROUND: Breast cancer (BC) is currently the most frequent tumor in women. Through the years, BC management has evolved towards conservative surgery. However, even minimally invasive surgery can cause neuromotor and/or articular impairments which can lead to permanent damage, if not adequately treated. AIM: To clinically evaluate upper ipsilateral limb function and the impact of certain post-surgical consequences arising after invasive or breast-conserving surgery for early BC, by intervening, or not intervening, with an early rehabilitation program. To investigate physical morbidity after sentinel (SLND) or axillary lymph node dissection (ALND) and after reconstructive surgery in the treatment of early BC. DESIGN: Observational prospective trial. SETTING: Inpatient and outpatient treatment. POPULATION: Eighty-three females participated in the study: 25 patients did not begin physiotherapy during hospitalization (Group A), 58 patients received early rehabilitation treatment (Group B). METHODS: The patients of Groups A and B were compared with respect to the following criteria: shoulder-arm mobility, upper limb function, and presence of lymphedema. All patients were assessed at 15-30, 60 and 180 days after surgery. RESULTS: Statistically significant differences, in favor of Group B, were encountered at the 180-day follow-up visit, especially with respect to articular and functional limitation of the upper limb. CONCLUSION AND CLINICAL REHABILITATION IMPACT: The results of the present study show that early assisted mobilization (beginning on the first postoperative day) and home rehabilitation, in conjunction with written information on precautionary hygienic measures to observe, play a crucial role in reducing the occurrence of postoperative side-effects of the upper limb.

Magnetic resonance cholangio-pancreatography versus endoscopic retrograde cholangio-pancreatography in the diagnosis of common bile duct stones: a prospective comparative study.

AIM: As it is a non-invasive method, magnetic resonance cholangiography (MRCP) has almost completely replaced endoscopic retrograde cholangiography (ERCP) in the diagnosis of pancreato-biliary diseases. The aim of this study was to evaluate sensitivity, specificity, diagnostic accuracy, positive predictive value (PPV) and negative predictive value (NPV) of MRCP in diagnosis of choledocholithiasis using ERCP/endoscopic sphincterotomy (ES) as gold standard. METHODS: For this study 140 individuals, suspected for lithiasis of the common bile duct (CBD), were enrolled. After a clinical and biochemical evaluation, patients underwent upper abdominal ultrasonography, then MRCP and diagnostic and/or operative ERCP. RESULTS: Only 120 out of 140 patients completed the study. MRCP diagnosed lithiasis of CBD in 84. ERCP confirmed the lithiasis in 73/84 patients who were submitted to ES. Eleven were negative after ES. ERCP documented stones in 10 patients among the 36 negative at MRCP; stones were detected only in four patients after ES. In 26 out of 36 patients negative at MRCP, ERCP confirmed this response: only 12 out of 26 patients underwent ES. The sensitivity, specificity, diagnostic accuracy, PPV and NPV of MRCP were: 88%, 72%, 83%, 87%, 72%. CONCLUSIONS: As the MRCP diagnostic yield is still limited with small stones, the question of which patient is the best candidate to ERCP/ES is still unsolved.

Endoscopic mucosal resection for large and giant sessile and flat colorectal polyps: a single-center experience with long-term follow-up.

BACKGROUND AND STUDY AIMS: This study examines efficacy, outcome, and complications of endoscopic mucosal resection (EMR) for large (> or = 20 mm) and giant (> or = 40 mm) sessile and flat colorectal polyps. PATIENTS AND METHODS: All EMRs carried out at our institution over a 9-year period, for large and giant sessile and flat colorectal polyps with an intensive and regular follow-up were evaluated. The rate of en bloc and piecemeal resection, complications, and recurrence were analyzed. RESULTS: A total of 148 polyps were resected in 148 patients. There were 113 large polyps (76.3 %) with a mean size of 25 +/- 4.7 mm (range 20 - 39 mm) and 35 giant polyps (23.7 %) with a mean size of 48.8 +/- 12.5 mm (range 40 - 100 mm). The most frequent location was the rectum, occurring in 43.2 %. All lesions were removed in a single session. En bloc resection was performed in 65 cases (43.9 %) and piecemeal in 83 (56.1 %). Procedural bleeding occurred in 13 EMRs (8.8 %), and one case of early and one case of delayed bleeding also occurred. There were two cases of postpolypectomy syndrome and one case of perforation. Malignancy (intramucosal and invasive cancer) was mostly present in polyps with sessile shape ( P = 0.0013). Follow-up colonoscopy was performed in 142 patients for a mean of 29.8 months. Recurrence was observed in 6/142 (4.2 %) patients and was found more in patients with giant polyps ( P = 0.014). CONCLUSIONS: In our experience EMR is a simple and safe procedure for removing large and giant sessile and flat colorectal polyps, and is associated with a very low risk of complication and local recurrence.

Cyanoacrylate glue in the management of gastric varices.

Gastric varices (GV) are less common than esophageal varices, but their management represents a particular challenge. When bleeding occurs is usually severe, requiring immediate supportive intensive care and has a high mortality rate. The best management of GV is supposed to be with a multidisciplinary approach and close cooperation between gastroenterologists, interventional radiologists and the surgical team. Many studies in literature reported high success rates with intravariceal injection of cyanoacrylate in acute GV bleeding. This agent obliterates the variceal lumen by solidification within the vein and more than 80% primary obliteration rates are achieved. In comparison with other endoscopic techniques as variceal band ligation or sclerotherapy with ethanolamine oleate, alcohol and sodium tetradecyl sulphate, cyanoacrylate has shown to be more effective, with a decrease in complications and mortality rates. The cyanoacrylate has shown effective also in the secondary prophylaxis with an incidence of re-bleeding that ranges between 15% and 30%. Actually, there is no scientific evidence supporting the application of cyanoacrylate in primary prophylaxis of bleeding from GV. Significant procedural, septic and embolic complications have been reported with cyanoacrylate glue injection. In conclusion, the endoscopic treatment with cyanoacrylate of actively bleeding GV, as well as the prophylaxis of the re-bleeding, is a safe and effective procedure and should be considered as a first-line therapy, whenever available.

Anger and ego-defence mechanisms in non-psychiatric patients with irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome is commonly accepted as a disorder closely influenced by affective factors, which can either trigger the symptoms or contribute to their persistence, independently from their aetiology. It has been previously documented that irritable bowel syndrome patients respond to a variety of emotional states (anger, fear and anxiety) with an increase in colonic motility. AIMS: The aim of this study was to evaluate the experience and the expression of anger and the prevalent ego-defence mechanisms in a group of non-psychiatric patients with irritable bowel syndrome. SUBJECTS: Fifty-two patients with irritable bowel syndrome (18 males, 34 females) and 100 healthy volunteers from the community (44 males, 56 females) matched for age, level of education and social-status were enrolled. METHODS: Assessment was conducted using the State-Trait Anger Expression Inventory and the Defence Mechanism Inventory. RESULTS: No important differences between the two examined groups were found using the State-Trait Anger Expression Inventory and Defence Mechanism Inventory. CONCLUSIONS: It can be hypothesised that stable personality features and habits, such as anger disposition and defence mechanisms, play only a marginal role in irritable bowel syndrome, while psychological and psychosocial influences may act as predisposing or precipitating factors which contribute to the pathogenesis or expression of irritable bowel symptoms.

An endoscopic approach to the management of surgical bile duct injuries: nine years' experience.

BACKGROUND: The evaluation of the endoscopic treatment of surgical bile duct injuries, especially in the management of post-operative strictures, remains controversial. AIM: The aim of this study was to evaluate the feasibility of using endoscopic management from a study of the clinical reports of two of the main endoscopy units in Sicily. PATIENTS AND METHODS: A total of 137 consecutive patients were selected. There were 85 simple biliary fistulas: 64 from the cystic duct stump; 19 from the gall bladder bed; and two from intra-hepatic bile ducts. There were 52 biliary lesions: 15 complete transections; 12 incomplete lesions of the common bile duct with six associated strictures; five complete or incomplete sections of the right antero-medial duct; and 20 incomplete strictures (without leak). RESULTS: The success rate was 96.3% for simple biliary fistulas. Endoscopic therapy was feasible only in 40.6% of lesions of the common bile duct or the right antero-medial duct (13/32), but with 100% success. In the case of strictures (with or without associated leak), there was a good outcome in 88.2% of patients who completed the therapeutic procedure. CONCLUSIONS: Endoscopic management of simple biliary fistulas and incomplete lesions of the common bile duct is the preferred approach. If continued for 12-24 months, with the placement of three or more 10F stents, the management of stenoses is guaranteed to yield good results.

Endoscopic treatment of Barrett's epithelium with Argon Plasma Coagulation. Long-term follow-up.

BACKGROUND: Barrett's esophagus (BE) is a premalignant condition for the development of esophageal adenocarcinoma. Recently, many endoscopic therapies based on thermal or photobiologic ablation of BE have been provided, with positive short-term results in 60-100% of cases, but long-term results are still lacking. The aim of this study is to evaluate long-term results of BE endoscopic ablation with Argon-Plasma Coagulation (APC). METHODS: Thirty-five consecutive patients were treated (every 3 weeks) with APC until the eradication of BE and the squamous epithelium restoration were assessed. During the treatment and the first 6 months of follow-up, patients received 40 mg/die omeprazole; then the proton pump inhibitors (PPI) dose was 20 mg/die. Endoscopic and histologic controls have been performed every 6 months. The study considered the fìrst 32 patients who completed at least 24 months of follow-up, whose median was 49.5 months (range: 24-60). RESULTS: The ablation of BE was achieved with a median of 2.0 APC sessions, without side- effects. The recurrence of SIM (specialized intestinal metaplasia) was detected in 3 patients, while nor dysplasia or cancer developed. CONCLUSIONS: Our results confirm that APC can lead both to eradication of BE and the restoration of squamous epithelium. As recent reports indicated the persistence of SIM beneath the new epithelium and even a neoplastic growth (adenocarcinoma) in the treated area, despite APC, 2 questions have arisen: is APC unable to radically ablate BE or on the contrary are these findings due to defects of the ablative technique needing improvement? To settle more precise conclusions, further investigation with larger numbers of patients and for longer follow-up is required.

Endoscopic clipping of a colocutaneous fistula following necrotizing pancreatitis: case report.

The case described here is of a 73-year-old male patient who developed a colocutaneous fistula following necrotizing pancreatitis, diagnosed by imaging and treated endoscopically by the application of an endoclip. Pancreatic and gastrointestinal fistulas, common complications of surgery for necrotizing pancreatitis, frequently require surgical treatment. Colonic perforations are the most difficult to treat surgically on account of the risk of peritonitis. A technique, namely, endoscopic clips application, has recently been developed to close anastomotic leakages and perforations of the oesophagus, stomach and colon. In the patient described here, endoscopic repair was technically easy and the good result was confirmed within a few days. In order to repair colonic fistulas following pancreatitis, application of endoclips could, in our opinion, provide a useful therapeutic option, feasible in selected patients.

Effects of intravenous TRH on growth hormone and cortisol serum levels in children and adolescents with insulin dependent diabetes mellitus.

The effects of an iv thyrotropin releasing hormone (TRH) bolus on serum growth hormone (GH) and cortisol levels were evaluated in 59 children and adolescents with insulin dependent diabetes mellitus (IDDM) and in 24 healthy, age-matched control subjects. In the IDDM group GH baseline levels sharply rose within 30 min after TRH and successively normalized. On the contrary, TRH injection failed to affect GH serum concentrations in the control group. The GH increase after TRH in IDDM patients was positively correlated to age, but unrelated to other variables, such as sex, pubertal stage, duration of disease, glycemia, glycosylated hemoglobin, thyrotropin and T4 concentrations. Twenty-one out of 59 diabetics and only 1/24 controls exhibited a paradoxical GH response to TRH, arbitrarily defined as a precocious increase (within 30 min), of more than 100% with respect to the baseline value, associated with a GH peak greater than 10 ng/ml. Eighteen IDDM patients underwent a second TRH test 12 to 24 months later and substantially exhibited the same GH pattern documented the first time. The mechanism responsible for such anomalous GH responsiveness to TRH in IDDM is unclear. However, it cannot be attributed to a nonspecific stress reaction, as proven by the lack of a concomitant increase of cortisol serum levels in the same subjects.
