Portal venous gas and pneumatosis intestinalis secondary to intestinal subocclusion: success of non-surgical management.

The association of intestinal and portal pneumatosis in the same patient usually occurs in intestinal ischemic-necrotic processes, with ominous prognosis. However, there are forms of presentation outside this context, with a radically different management and evolution. We present the case of a patient with portal and gastric pneumatosis, managed conservatively successfully. The clinical presentation and a multidisciplinary management will be critical in the decision-making process to obtain favorable results.

Spanish Experience with Latero-Lateral Duodeno-Ileostomy + Sleeve Gastrectomy with Magnet Anastomosis System.

BACKGROUND: The partial diversion of intestinal contents facilitates achieving and maintaining weight loss and improving glycemic control in patients with obesity and with or without T2DM. The purpose of this study is to report our experience and 1-year follow-up with novel modification of SADI-S. METHODS: This study is a part of a multicentric trial of patients that underwent primary side-to-side duodeno-ileostomy and sleeve gastrectomy (SG) with GT metabolic solutions magnetic anastomosis system. Feasibility, safety, and initial efficacy were evaluated. RESULTS: The mean age of the patients included was 48 ± 8.75 years and the preoperative BMI was 43.32 ± 2.82 kg/m2. The complications were present in 30% of patients. The anastomosis patency was confirmed by the passage of radiological contrast under fluoroscopy at a mean of 17 days (17-29 days), and the mean expulsion time was 42 days (32-62). The mean diameter of the anastomosis after the magnet expulsion was 13.8 × 11.4 mm. The percentage of total weight lost at 1 year was 38.68 ± 8.48% (p < 0.001). The percentage of excess weight loss 82.5 ± 18.44% (p < 0.001) and improvements in glucose profiles were observed. Mean baseline HbA1c 5.77 ± 0.31% was reduced to 5.31 ± 0.26% (p < 0.024). CONCLUSIONS: Latero-lateral duodeno-ileostomy + SG with magnetic duodenal bipartition is afeasible and reasonably safe technique and induces weight loss in patients with obesity and improvement of glycemic control. This modification could be considered as an option to standard SADI-S or as a first step in two stages procedure. However, larger studies are needed.

Efficacy and safety of ERCP in a low-volume hospital.

BACKGROUND AND AIMS: there is little scientific evidence on the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) performed in low-volume hospitals; however, in our country, it is growing up its implementation. The objectives of our study were to evaluate the efficacy and safety of this technique performed by two endoscopists with basic training in a center of this nature and analyze the learning curve in the first procedures. PATIENTS AND METHODS: single-center retrospective study of the first 200 ERCP performed in our hospital (analyzing the evolution between the first 100 and 100 following procedures), comparing them with the quality standards proposed in the literature. RESULTS: from February 2009 to April 2011, we performed 200 ERCP in 169 patients, and the most common indications were: Choledocholithiasis (77 %), tumors (14.5 %) and other conditions (8.5 %). The cannulation rate rose from 85 % in the first 100 ERCPto 89 % in the next 100 procedures, clinical success from 81 % to 87 %, decreasing the post-ERCP acute pancreatitis rate from 11 % to 4 %, upper gastrointestinal bleeding (UGIB) from 3 % to 2 % and acute cholangitis from 4 % to 1 %. There was a death from a massive UGIB in a cirrhotic patient in the first group of patients and a case of biliary perforation resolved by surgery in the second one. CONCLUSIONS: the results obtained after performing 200 procedures support the ability to practice ERCP in low-volume hospitals obtaining levels of efficacy and safety in accordance with published quality standards.

[Kaposi's sarcoma with colorectal and anal canal involvement]. / Sarcoma de Kaposi con afectación colorrectal y del canal anal.

Kaposi's sarcoma (KS) is a low-grade vascular tumor, with four main variants, one of which is fairly prevalent in HIV-infected patients. Mucocutaneus and lymph node involvement is characteristic. The gastrointestinal tract is involved in 40% of patients, but rectal and anal canal involvement is exceptional. We report the case of a 39-year-old HIV-infected man with an unusual presentation of KS with colorectal and anal canal involvement in the absence of cutaneous disease. The patient was treated with highly active antiretroviral therapy and systemic chemotherapy, with partial response. Local radiation therapy of the rectum produced local remission.

Usefulness of penicillamine-stimulated urinary copper excretion in the diagnosis of adult Wilson's disease.

OBJECTIVE: Diagnosis of Wilson's disease (WD) is reliant on liver biopsy (LB) and measurement of hepatic copper. The aim of this study was to determine the usefulness of penicillamine-stimulated urinary copper excretion (PS-UCE), a non-invasive diagnostic test, for the diagnosis of WD in adults. MATERIAL AND METHODS: In this prospective study of patients with suspected WD, total serum copper, ceruloplasmin, basal 24-h UCE and PS-UCE levels were measured. LB with copper determination was performed in those patients with persistent hypertransaminasemia and low ceruloplasmin or basal UCE > 40 microg/24 h. Diagnosis was established if the ceruloplasmin level was found to be < 20 mg/dl and hepatic copper > 250 microg/g. Results. A total of 115 patients were studied; LB was performed in 43, and WD was diagnosed in 6 (13.9%). Significant differences between WD and non-WD patients were found for basal UCE (WD: median 134.3 microg/24 h versus non-WD: median 19.0 microg/24 h (p < 0.05)) and PS-UCE (WD: median 1284.0 microg/24 h versus non-WD: median 776.0 microg/24 h; p < 0.01). In the ROC (receiver-operated curve) analysis, PS-UCE was the best discriminant between WD and non-WD (area under the curve (AUC) = 0.911, best cut-off point 1057 microg/24 h, 100% sensitivity, 82.3% specificity). CONCLUSIONS: PS-UCE is probably a useful non-invasive test in the diagnosis of WD, improving the selection of patients for diagnostic liver biopsy. Patients with PS-UCE under 1057 microg/24 h only rarely will suffer from WD and are unlikely to benefit from LB.

[Constitutional syndrome associated to metformin induced hepatotoxicity]. / Síndrome constitucional asociado a hepatotoxicidad por metformina.

Metformin is an oral antidiabetic agent frequently used to manage type II diabetes. This drug produces nonspecific gastrointestinal symptoms in 5-20% of patients and, more rarely, has also been associated with severe adverse effects such as lactic acidosis. Only a few isolated cases of hepatotoxicity due to this drug have been documented. We report the case of an 83-year-old man with constitutional syndrome and hepatic biochemical alterations, which were attributed to metformin after ruling out an oncologic etiology and observing complete clinical and biochemical resolution after withdrawal of the drug.

[Hereditary hemochromatosis: phenotypic study in a Spanish population]. / Hemocromatosis hereditaria: estudio fenotípico de una población española.

BACKGROUND AND OBJECTIVE: Hereditary hemochromatosis (HH) displays an important phenotypic variability and is a disease influenced by many factors. PATIENTS AND METHOD: We included 88 patients with HH. Main clinical and laboratory data were analyzed, and the influence of 6 variables on intensity of iron overload was evaluated. RESULTS: In 38.6% (95% confidence interval [CI], 28.5-49.6%) patients, none of the typical symptoms of the disease was observed. 30,9% (95% CI, 21.7-41.7%) showed abnormalities of the glucose metabolism. We detected an increase in sideremia in 75.0% patients (CI 95%, 64.4-83.3%), transferrin saturation index (TSI) in 95.4% (CI 95%, 88.1-98.5%) and ferritin in 93.2% (CI 95%, 85.1-97.1%) of patients. In addition, we observed increased values of GPT and alkaline phosphatase in an appreciable percentage of patients. Ferritin was significantly higher in men (1329.4 [913.2] ng/ml vs 656.6 [644.5] ng/ml; p < 0.001), and in those older than 45 years (1293.9 [1006.9] ng/ml vs 868.9 [642.8] ng/ml; p = 0.023] and in not blood donors (1205.2 [926.8] vs 524.8 [365.9] ng/ml; p < 0.001). TSI was 81.9% (19.6) in C282Y homozygotes and 65.7% (19.2) in the rest of HFE genotypes (p = 0.002). Differences of TSI with regard to sex, age or status of blood donor were not detected. Sideremia was significantly higher in patients infected by virus C (251.8 [24.4] microg/dl vs 182.8 [45.8] microg/dl; p = 0.001). CONCLUSIONS: HH patients have a noticeable phenotypic variability, and for that reason clinical symptoms are only orientative for the diagnosis. The relationship between HH and glucose metabolism should be investigated further. Iron parameters can be influenced by age, sex, HFE genotype, blood donation, alcohol intake and hepatitis C virus infection.

[Chronic urticaria and Helicobacter pylori]. / Urticaria crónica e infección por Helicobacter pylori.

BACKGROUND AND OBJECTIVE: We intended to analyze the influence of Helicobacter pylori eradication on the clinical evolution of patients with chronic idiopathic urticaria. PATIENTS AND METHOD: The evolution of dermatological symptoms after eradication was studied in a group of 55 patients previously diagnosed with chronic idiopathic urticaria who were infected by Helicobacter pylori. RESULTS: There was a partial or complete improvement in 74.6% (CI 95%, 61-85%) of studied patients. We could not demonstrate a statistically significant influence of sex, age or endoscopic lesions on the clinical evolution of urticaria after eradication. CONCLUSIONS: These results suggest a possible usefulness of Helicobacter pylori eradication in some patients with chronic idiopathic urticaria. Controlled and randomized studies are necessary to confirm it.
