    Comparison of tomographic and colonoscopic diagnoses in the presence of colonic wall thickening

    Introduction and objective: Colonic wall thickening is a common condition in a number of benignant and malignant diseases. This study investigated the accuracy of radiological diagnoses in patients diagnosed with colonic wall thickening using multislice CT (MDCT). Materials and method: Files of patients with colonic wall thickening diagnosed with 64-slice MDCT were reviewed retrospectively. The colonoscopy results of these patients were grouped under neoplastic process (cancer and adenomatous polyp), inflammatory bowel disease (IBD), diverticulitis and other etiology (nonspecific events, ischemic colitis, solitary rectal ulcer, external compression, secondary to volvulus and radiotherapy), and the results were statistically evaluated. p values < 0.05 were considered statistically significant. Results: The study was performed on 505 files (290 males [57.4%], 215 females [42.6%], mean age: 49.15 ± 18.4 years). CT and colonoscopic diagnoses were reviewed and the following CT to colonoscopy ratios was observed: neoplastic process: 44.4% vs. 40.2%; IBD: 42.4% vs. 42.4%; diverticulitis: 4% vs. 4.2%; other etiology: 9.3% vs. 3.2%. Colonoscopy failed to identify pathology in 9.9% of the patients. The sensitivity, specificity, PPV, NPV and accuracy of CT were 95.6%, 90.4%, 87.1%, 96.8% and 92.4%, respectively, in detecting neoplastic processes; 97.2%, 97.9%, 97.2%, 97.9% and 97.6%, respectively, in detecting IBD; 90.5%, 99.8%, 95%, 99.6% and 99.4%, respectively, in detecting diverticulitis, and 50%, 96,7%, 62.5%, 94.6% and 92%, respectively, in detecting other etiology. Conclusion: While, accuracy of 64 slice-CT in diagnosing colonic wall thickenings secondary especially to neoplastic processes, IBD and diverticulitis was significantly higher, but differential diagnosis is challenging in pathologies due to other etiologies.

    Gastroenterology cases of cutaneous leukocytoclastic vasculitis.
    (2013-01-01) SENTURK, H; ARABACI, ELİF; YILDIZ, KEMALETTİN; CAKIRCA, MUSTAFA; ÇıKRıKÇıOĞLU, MA; ERGUN, F; DANALIOGLU, A; KOCAMAN, O; KARATOPRAK, CUMALİ; ARABACI, ELİF; YILDIZ, KEMALETTİN; ÇAKIRCA, MUSTAFA; ŞENTÜRK, HAKAN
    Rarely, leukocytoclastic vasculitis can result from ischemic colitis, inflammatory bowel disease, and cryoglobulinemia. There is no established standard for the treatment of leukocytoclastic vasculitis associated with gastroenterologic diseases. This paper presents three cases of leukoytoclastic vasculitis, each of which is associated with a different gastroenterologic condition: ischemic colitis, Crohn’s disease, and chronic hepatitis C. Each condition went into remission by treatment of leukocytoclastic vasculitis, regardless of the underlying disease.

    Acromegaly can be associated with impairment of LES relaxation in the oesophagus
    (2015-09-01) Ilhan, MAHMUT MUZAFFER; DANALIOGLU, Ahmet; Turgut, SEDA; Karaman, Ozcan; Arabaci, ELİF; Tasan, ERTUĞRUL; İLHAN, MAHMUT MUZAFFER; TURGUT, SEDA; KARAMAN, ÖZCAN; ARABACI, ELİF; TAŞAN, ERTUĞRUL
    Introduction: Although prolonged small intestine and colonic transit time has been demonstrated in acromegaly patients, the influence of acromegaly on oesophagus motility and the pathological mechanisms involved are still not clarified. We aimed to investigate manometric measurements to ascertain whether oesophagus motility is affected in active acromegaly patients. Material and methods: The study was performed in an institutional referral centre at a tertiary care hospital. Twenty-three acromegaly patients (mean age 43.2 ± 13.2 years) and 25 sex- and age-matched healthy control subjects (mean age 48.6 ± 7.9 years) were recruited to a case-control study. Oesophageal manometry was performed using MMS (Medical Measurement Systems, Netherlands) Solar GI — Air Charged Intelligent Gastrointestinal Conventional Manometry. Results: In manometric measurements the lower oesophageal sphincter pressure was 18 ± 7 mmHg in acromegaly patients and 15.6 ± 4.4 mm Hg in controls, and there was no significant difference (p = 0.17). The percentage of relaxation was 64.8% and 81.8%, respectively, and it was significantly lower in acromegaly patients than in controls (p < 0.001). Additionally, the duration of relaxation was found to be 4 ± 1.9 seconds and 5 ± 1.7 seconds in patients and controls, respectively (p = 0.049). Conclusions: Our study has demonstrated a significant reduction in the percentage and duration of lower oesophageal sphincter relaxation in oesophagus motility even in acromegaly patients without any gastrointestinal symptoms. Further clinical and pathophysiological studies are required to clarify the underlying mechanisms of gastrointestinal motility disorders in acromegaly
