Introduction: The aim of the study was to describe the levels of circulating monocyte/macrophage pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-8) and an anti-inflammatory cytokine (IL-10) in inflammatory bowel disease (IBD) and colorectal cancer (CRC) patients and healthy controls. Materials and Methods:The study was conducted on 15 healthy individuals, 20 patients with ulcerative colitis (UC), 12 with Crohn's disease (CD), and 15 with CRC (Dukes' stage B). Blood serum cytokine levels were measured by ELISA. Results: The patients with UC had significantly higher levels of the pro-inflammatory cytokines and of circulating IL-10 than the healthy controls. The patients with CD and CRC had the same specific pattern of serum cytokines of significantly elevated levels of the pro-inflammatory cytokines, but the IL-10 levels were within the range found in the healthy individuals. Conclusions: Thus our results demonstrate that both IBD and CRC are linked with an intensified production of a wide array of monocyte/macrophage pro-inflammatory cytokines which is not accompanied by elevated levels of circulating IL-10, except for its insufficiently inhibitory elevation in UC patients.
AIMS: The purpose of this study was to evaluate the effects of overweight on surgical and long-term outcomes in a Western population of patients with gastric cancer (GC).METHODS: An electronic database of all patients with resectable GC treated between 1986 and 1998 at seven university surgical centres cooperating in the Polish Gastric Cancer Study Group was reviewed. Overweight was defined as a body mass index (BMI) of 25 kg/m 2 or higher.RESULTS: Four hundred and ninety-two of 1992 (25%) patients were overweight.Postoperatively, higher BMI was associated with higher rates of cardiopulmonary complications (16% vs 12%, P=0.001) and intra-abdominal abscess (6.9% vs 2.9%, P<0.001).However, other complications and mortality rates were unaffected. The median diseasespecific survival of overweight patients was significantly higher (36.7 months, 95%confidence interval (CI) 29.0 to 44.4) than those with BMI<25 kg/m 2 (25.7 months, 95%CI23.2 to 28.1; P=0.003). These differences were due to the lower frequencies of patients with T3 and T4 tumours, metastatic lymph nodes, distant metastases, and non-curative resections.A Cox proportional hazards model identified age, depth of infiltration, lymph node metastases, distant metastases, and residual tumour category as the independent prognostic factors.CONCLUSIONS: Overweight is not the independent prognostic factor for long-term survival in a Western-type population of GC.
MSB as a supplemental therapy can reduce the frequency of selected clinical symptoms in patients with IBS, without significant influence on reducing symptom severity.
The management of enteroatmospheric fistula (EAF) in open abdomen (OA) therapy is challenging and associated with a high mortality rate. The introduction of negative pressure wound therapy (NPWT) in open abdomen management significantly improved the healing process and increased spontaneous fistula closure. Retrospectively, we analysed 16 patients with a total of 31 enteroatmospheric fistulas in open abdomen management who were treated using NPWT in four referral centres between 2004 and 2014. EAFs were diagnosed based on clinical examination and confirmed with imaging studies and classified into low (<200 ml/day), moderate (200-500 ml/day) and high (>500 ml/day) output fistulas. The study group consisted of five women and 11 men with the mean age of 52·6 years [standard deviation (SD) 11·9]. Since open abdomen management was implemented, the mean number of re-surgeries was 3·7 (SD 2·2). There were 24 EAFs located in the small bowel, while four were located in the colon. In three patients, EAF occurred at the anastomotic site. Thirteen fistulas were classified as low output (41·9%), two as moderate (6·5%) and 16 as high output fistulas (51·6%). The overall closure rate was 61·3%, with a mean time of 46·7 days (SD 43·4). In the remaining patients in whom fistula closure was not achieved (n = 12), a protruding mucosa was present. Analysing the cycle of negative pressure therapy, we surprisingly found that the spontaneous closure rate was 70% (7 of 10 EAFs) using intermittent setting of negative pressure, whereas in the group of patients treated with continuous pressure, 57% of EAFs closed spontaneously (12 of 21 EAFs). The mean number of NPWT dressing was 9 (SD 3·3; range 4-16). In two patients, we observed new fistulas that appeared during NPWT. Three patients died during therapy as a result of multi-organ failure. NPWT is a safe and efficient method characterised by a high spontaneous closure rate. However, in patients with mucosal protrusion of the EAFs, spontaneous closure appears to be impossible to achieve.
BackgroundChronic anal fissure (CAF) is a linear split of the anoderm. The minimally invasive management of CAF such as botulinum toxin (BT) injection is recommended. However, the exact efficient dose of BT, number of injections per session and the injection sites are still debatable. The aim of this analysis was to assess the dose-dependent efficiency of botulinum toxin injection for CAF. MethodsPubMed and Web of Science databases were searched for terms: “anal fissure” AND “botulinum toxin.” Studies published between October 1993 and May 2015 were included and had to meet the following criteria: (1) chronic anal fissure, (2) prospective character of the study, (3) used simple BT injection without any other interventions and (4) no previous treatment with BT.ResultsA total of 1577 patients from 34 prospective studies used either Botox or Dysport formulations were qualified for this meta-analysis. A total number of BT units per session ranged from 5 to 150 IU, whereas the efficiency across analyzed studies ranged from 33 to 96 %. Surprisingly, we did not observe a dose-dependent efficiency (Spearman’s rank correlation coefficient, ρ = 0.060; p = 0.0708). Moreover, there were no BT dose-dependent postoperative complications or fecal incontinence and significant difference in healing rates compared BT injection into the anal sphincter muscles.ConclusionsBT injection has been an accepted method for the management of CAF. Surprisingly, there is no dose-dependent efficiency, and the postoperative incontinence rate is not related to the BT dosage regardless the type of formulation of botulinum neurotoxin used. Moreover, no difference in healing rate has been observed in regard to the site and number of injections per session.
