Comparison of Postoperative Morbidity in Elderly Patients who Underwent Pancreatic Resection

Background/Aims: Operative indications for pancreatectomy in elderly patients with pancreatic disease remain controversial. We examined clinicopathological characteristics and early outcomes in each generation of 147 patients who underwent pancreatectomy. Methodology: Patients were divided into four groups: Group 1 (n=15, 10%), young patients <50 years old; Group 2 (n=65; 44%), patients at 50-69 years old; Group 3 (n=61, 42%), patients at 70-79 years old and Group 4 (n=6, 4%), elderly patients <80 years old. Clinicopathological and surgical parameters were examined, including estimation of physiological ability and surgical stress consisting of preoperative risk score (PRS), surgical stress score (SSS) and comprehensive risk score (CRS). Results: Prevalence of comorbidity and American Society of Anesthesiologists (ASA) score increased significantly with increasing patient age (p<0.05). Extent of pancreatectomy and lymphadenectomy did not differ between groups and surgical records were similar. Tumor stage, post-operative course and complications were similar between groups. PRS and CRS increased significantly with increasing patient age (p<0.05) but SSS did not. Univariate analysis identified presence of systemic comorbidity, ASA score =2 and PRS =0.32 as factors associated with postoperative complications, but no independent predictive parameters were identified on multivariate analysis. Conclusions: Careful management and adequate decisions regarding pancreatectomy upon identification of comorbidity, ASA score and PRS are important in elderly patients with pancreatic disease before pancreatectomy

Significance of serum palmitoleic acid levels in inflammatory bowel disease

Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn’s disease (CD), are chronic intestinal diseases of unknown etiology that present with variable disease extents and outcomes. The use of biomarkers for the diagnosis and management of IBDs is considered beneficial. Palmitoleic acid (PO) is an adipose tissue-derived mono-unsaturated free fatty acid that potentially serves as a lipokine in metabolic and inflammatory diseases. The aim of this study was to investigate the significance of PO levels in the serum of patients with UC and CD. The study included patients with UC (n = 22), patients with CD (n = 35), and controls (n = 22). The levels of serum PO were analyzed using gas chromatography. The association of serum PO levels with the clinical features and disease outcomes in IBD was examined. Serum PO levels were significantly higher in patients with CD than in controls, whereas no difference in these levels was observed between patients with UC and controls. Serum PO levels were significantly associated with the CD activity index. Additionally, high serum PO levels were associated with an increased risk of surgical intervention requirement during follow-up. In a pilot study with a few patients, high PO levels were observed in the mesenteric tissue in the active disease site of patients with CD (n = 7) compared with those with colon cancer (n = 6). Elevated serum PO levels might serve as a marker for local inflammation and prognosis in patients with CD

High Serum Vaspin Concentrations in Patients with Ulcerative Colitis

Background: Adipocytokines are associated with energy homeostasis and mediate various immune responses and inflammatory processes. Vaspin is a novel adipocytokine that is thought to exhibit anti-inflammatory effects. Aim: We aimed to evaluate serum vaspin levels in inflammatory bowel disease (IBD) and determine its possible associations with the course and to clarify its intestinal localization. Methods: Serum samples were obtained from patients with Crohn\u27s disease (CD; n = 30) and ulcerative colitis (UC; n = 33) and from healthy volunteers (controls; n = 26). Enzyme-linked immunosorbent assays were performed for all patients. Vaspin immunohistochemical staining was performed for intestines affected with IBD. Results: Serum vaspin concentrations were significantly higher in patients with UC than in patients with CD and controls (422.9 ± 361.9 vs. 163.4 ± 116.2 vs. 147.5 ± 89.4 pg/mL, respectively; P < 0.01). There was no difference in the serum vaspin concentrations between the patients with CD and controls. There was also no difference in the serum vaspin concentrations between the patients with active IBD and those with inactive IBD. However, the serum vaspin concentrations of most patients with UC increased after remission induction. Vaspin was expressed in the adipocytes of the mesenteric adipose tissues but not in the epithelial or inflammatory cells of large intestines of the patients with IBD. Conclusions: Serum vaspin concentrations are elevated in patients with UC and increase further after remission induction, suggesting that vaspin may aid the auxiliary diagnosis of UC and may be useful for assessing disease activity in patients

Sarcoidosis Accompanied by Systemic Lupus Erythematosus and Autoimmune Hepatitis

A 52-year-old woman was admitted to our hospital for further examination of blurred vision, abnormal lung shadows and an elevated level of angiotensin-converting enzyme. Sarcoidosis was suspected, however, careful history taking revealed the existence of photosensitivity and polyarthralgia. Laboratory tests showed lymphocytopenia, liver dysfunction, hypergammaglobulinemia, and positive anti-nuclear, anti-double stranded DNA and anti-smooth muscle antibodies. Liver biopsy examination showed chronic active hepatitis. She was diagnosed with the triplex of sarcoidosis, systemic lupus erythematosus and autoimmune hepatitis. Marked improvement was noted after corticosteroid therapy

New insertion method of transnasal ileus tube for small bowel obstruction: Anterior balloon method.

BACKGROUND:Small bowel obstruction (SBO) is usually caused by postoperative adhesions and malignant disease, and decompression is effective for SBO. Our previous case report suggested that a new transnasal ileus tube insertion method, the anterior balloon method (ABM), could achieve decompression for adhesive SBO. AIMS:The study aimed to investigate the effectiveness of a new method for inserting transnasal ileus tubes in patients with SBO. METHODS:Altogether, 134 patients with small bowel obstruction treated from January 2011 to December 2017 were reviewed. The patients were categorized into two groups: those with the new method that inserts an anterior balloon (ABM group: 52 patients, 2014-2017) versus those with the ordinary insertion method (OIM group: 82 patients, 2011-2014). RESULTS:The patients' characteristics and symptoms on admission were similar in the ABM and OIM groups. Adhesions were the main cause of ileus in the two groups. The insertion time duration was significantly shorter in the ABM group than in OIM group (28.4 ± 9.1 vs. 33.5 ± 13.0 min; p = 0.01). The ABM group also had significantly longer tubes than OIM group (222.4 ± 32.2 vs. 157.4 ± 31.7 cm; p < 0.001), which resulted in a significantly shorter time until clinical symptoms were relieved in ABM group. There were no significant differences in adverse events between the two groups. CONCLUSIONS:The ABM group had shorter insertion duration and longer tubes than those of OIM group. The ABM might become a preferred therapeutic choice to achieve decompression in patients with SBO

Comparison of sedation between the endoscopy room and operation room during endoscopic submucosal dissection for neoplasms in the upper gastrointestinal tract

Abstract Background The present study was performed to compare the safety of sedation during endoscopic submucosal dissection (ESD) in the endoscopy room versus operation room. Methods In total, 297 patients with gastrointestinal tumors who underwent ESD from January 2011 to December 2016 were retrospectively reviewed. The patients were divided into two groups: those who underwent ESD in the endoscopy room without propofol (Group E) versus operation room with propofol (Group O). The patient, tumor, and procedure characteristics; adverse events; and treatment outcomes were compared between the two groups. Results The patient and tumor characteristics, including age (73.6 ± 8.2 vs. 72.5 ± 9.1 years), comorbidities, and tumor size and histology, were not different between Groups E and O. The ESD procedure time was comparable between Groups E and O (105.4 ± 70.4 vs. 106.5 ± 64.4 min), and the anesthesia time was equivalent (138.3 ± 78.1 vs. 148.4 ± 68.8 min). There were no significant differences in adverse events between the two groups. During the ESD procedure, desaturation occurred significantly more often in Group E than O (12.9% vs. 4.0%, P = 0.021, odds ratio: 3.53, 95% CI: 1.17–14.4). The recovery time after ESD was significantly longer in Group E than O (180 (100–360) vs. 90 (0–180) min, P < 0.001). Conclusions A decreased desaturation rate and shorter recovery time after ESD were the advantages of sedation in the operation room with propofol compared with sedation in the endoscopy room. These findings warrant further exploration of the advantages of safe and effective ESD for upper gastrointestinal neoplasms in the operation room
