Background
Altered gastric anatomy following laparoscopic sleeve gastrectomy (LSG) is likely to induce upper gastrointestinal (GI) symptoms. Published studies, however, have focused mainly on gastroesophageal reflux disease (GERD). This study aims to evaluate LSG's impact on the prevalence of upper GI symptoms and to assess the effects of time from surgery, weight loss, and proton pump inhibitor (PPI) therapy.Methods
The validated Rome III Criteria symptom questionnaire for upper GI symptoms, including quality of life items, has been self-administered to 97 patients who underwent LSG. Symptoms were analyzed either separately or altogether to classify patients in GERD or dyspepsia, subdivided in epigastric pain (EPS) and post-prandial distress (PDS) syndromes.Results
Before LSG, 52.7 % of the patients were asymptomatic, 27.0 % had GERD, and 8.1 % had dyspepsia (2.7 % EPS, 5.4 % PDS). After a median follow-up of 13 months, 91.9 % of the patients complained of upper GI symptoms, the most prevalent being PDS (59.4 %). GERD prevalence did not differ before and after LSG. The only symptom strongly related to LSG was dysphagia (OR 4.7, 95 % CI 1.3–20.4, p?=?0.015), which was present in 19.7 % of the patients and mainly associated with PDS rather than GERD. GI symptoms, however, did not have a great impact on quality of life. Time from surgery, weight loss after surgery, as well as concomitant PPI, did not influence the symptoms.Conclusions
After a median follow-up of 13 months, PDS-like dyspepsia, rather than GERD, was the main complaint, both poorly responding to PPI therapy. A longer follow-up will be necessary to evaluate their future persistency. 相似文献13.

BackgroundThe aim of this study was to evaluate the long-term effects of laparoscopic sleeve gastrectomy (LSG) on type 2 diabetes mellitus (T2DM) and other related co-morbidities in severely obese patients.MethodsFrom May 2003 to July 2008, 33 morbidly obese diabetic patients (20 with body mass index [BMI]>50 kg/m2) underwent LSG. A total of 23 females and 10 males participated, with a mean age of 49.3±8 years, mean preoperative BMI of 52.1±8.5 kg/m2, mean fasting plasma glucose (FPG) of 143.2±47.9 mg/dL, mean glycosylated hemoglobin (HbA1c) of 7.3%±1.4%, and a mean T2DM duration of 7 years. All patients had a 36-month follow-up, and 13 had a 60-month follow-up.ResultsTwenty-nine patients (87.8%) discontinued antidiabetic medications 3 months after LSG, (mean BMI of 42.8±7.8 kg/m2; FPG of 104.5±22.1 mg/dL; HbA1c of 5.3%±.4%). At 36 months, 22 of 26 LSG patients (84.6%) had normal FPG and HbA1c values without antidiabetic therapy. At the 60-month follow-up, 10 of 13 patients (76.9%) had normal FPG and HbA1c values without antidiabetic therapy. The Framingham risk score decreased significantly from 9.7% preoperatively to 4.7% postoperatively. No new diabetic retinopathy occurred during the whole period of observation.ConclusionsThis study confirms the efficacy of LSG in the treatment of T2DM and indicates that, at both 36- and 60-month follow-ups, LSG can provide a significant percentage of treated patients with a prolonged remission of T2DM, with diminished cardiac risk factors and no development of diabetic retinopathy. These results compare favorably with those reported after standard medical therapy. 相似文献

Bidens pilosa is an Asteraceae widely used in traditional medicine for the treatment of various ailments including pain and inflammation. The present work was undertaken to assess the analgesic and antiinflammatory properties of the ethyl acetate fraction of methylene chloride/methanol (1:1) extract of leaves of Bidens pilosa at the gradual doses of 50, 100 and 200 mg/kg in mice and rats, respectively. The analgesic properties of Bidens pilosa were investigated using the acetic acid writhing, hot plate, capsaicin and formalin-induced pain models. This was followed by a study of the antiinflammatory properties using carrageenan, dextran, histamine and serotonin to induce acute inflammation in rat hind paw. The extract provided a significant (p < 0.01) reduction in pain induced by all four models of nociception. It also presented significant (p < 0.05) antiinflammatory activity in all four models of acute inflammation. These results show that the ethyl acetate fraction of methylene chloride/methanol (1:1) of Bidens pilosa has both analgesic and antiinflammatory properties. The qualitative analysis of the fraction by the high-performance liquid chromatography (HPLC) fingerprint revealed the presence of two flavonoids, namely quercetin and iso-okanin, known to have antiinflammatory and antinociceptive properties, which could be responsible for the analgesic and antiinflammatory effects observed. 相似文献

Summary. Chronic lymphocytic leukaemia (CLL) is known to be a stable monoclonal neoplasm. In contrast to early studies demonstrating no more than two hybridizing immunoglobulin heavy chain bands corresponding to the two expected alleles, we have demonstrated an unexpected multiband pattern when the HindIII-digested DNA samples from 38 CLL patients were analysed by Southern blot hybridization using JH and Cμ gene probes. In order to characterize the genetic basis for the multiband pattern, we molecularly cloned the immunoglobulin heavy chain genes of one of the patients whose leukaemic DNA sample demonstrated three hybridizing JH bands and a loss of the germline band. The cloned rearranged immunoglobulin genes could be divided, based on the restriction mapping and the hybridization with the various probes, into two basic patterns representing two alleles. In one of the cloned rearranged immunoglobulin genes a secondary rearrangement occurred that resulted in the addition of 300 base-pair long sequence into the switch region, and the creation of a HindIII restriction site.
The results of the study suggest that clonal evolution occurs in some CLL, and that many of these neoplasms are indeed oligoclonal due to the accumulation of secondary genetic changes. 相似文献

COX2 is an inducible cyclooxygenase implicated in the metastasis and migration of tumour cells. In neuroblastoma, COX2 expression has been detected in both cell lines and tumours. The treatment of neuroblastoma cells in vitro with celecoxib, a COX2 inhibitor, induces apoptosis. The aim of this study was to investigate the role of COX2 in neuroblastoma tumour biology by creating a cell line in which COX2 could be conditionally expressed. Xenograft studies showed that the conditional expression of COX2 enhanced tumour growth and malignancy. Elevated COX2 expression enhanced the proliferation and migration of neuroblastoma cells in vitro. However, elevated COX2 expression or variation between cell lines did not affect sensitivity to the COX2 inhibitor celecoxib, indicating that celecoxib does not promote cell death through COX2 inhibition. These data show that increased COX2 expression alone can enhance the tumorigenic properties of neuroblastoma cells; however, high levels of COX2 may not be a valid biomarker of sensitivity to non-steroidal anti-inflammatory drugs such as celecoxib. 相似文献
