Complication of endoscopic tattooing: a case report of covered perforation
2016
Aim Laparoscopy is considered a good approach in treatment of colorectal neoplastic diseases; the endoscopic tattooing is then recommended (Evidence Level III and grade of recommendation A) to mark a lesion or a polypectomy site for intraoperative identification. We describe the case of perforation after tattoing treated conservatively. Case report 63 years old woman, underwent colonoscopy for lipoma tattooing with India ink SPOT® solution kit and saline test. Immediately after the procedure the patient has been referred the appearance of colic epi-mesogastric pain and fever; Computed Tomography (CT) without MDC identified an irregular thickening of transverse colon with some microbubbles c…
Age-dependent shift-to-the-right in the localization of colorectal adenomas.
1987
The age-dependent prevalence and topographical distribution of colorectal adenomas was investigated in 1006 unselected autopsies (554 males and 452 females) in Mainz, FRG. In 200 out of 1006 autopsies (19.8%) a total of 498 adenomas of the large intestine were detected. The percentage of patients with adenomas increased continuously with age. Only 6% of all adenomas were localized in the caecum and 8% in the rectum, whereas all the other adenomas were distributed rather evenly throughout the ascending colon (23%), the transverse colon (25%), the descending colon (15%) and the sigmoid colon (23%). Analyzing the topographical distribution of adenomas for definite age groups (40-59, 60-69, 70-…
Effect of epidural anesthesia on colorectal anastomosis: a tonometric assessment.
1997
PURPOSE: Epidural anesthesia is believed to benefit colorectal anastomotic blood flow because of the sympathetic blockade it produces. Our purpose is to measure with tonometry the effect of epidural anesthesia on colorectal anastomotic oxygenation. PATIENTS AND METHODS: Fifteen patients operated on for rectal cancer (radical anterior resection) were monitored postoperatively using tonometers placed in the stomach (celiac trunk), transverse colon (superior mesenteric artery), and the anastomotic area during the operation. An epidural catheter was placed at L1-2, and on the first postoperative day, 8 ml of bupivacaine (0.25 percent) was administered. The anesthetic effect extended up to T-4. …
Pyelotransverse pyelocolostomy: an alternative method for high urinary diversion in patients with extended bilateral ureter damage.
1991
After previous radiation due to pelvic malignoma or after multiple operations, the ileal conduit as well as sigmoid conduit are associated with an increased rate of complications. In these patients, the middle and distal ureter often cannot be considered for reimplantation due to fibrosis. High anastomosis to a bowel segment which is undamaged proves favorable. The transverse colon, conveniently situated in the cranial abdomen, is close enough to the kidneys for such a high anastomosis and is mostly spared from irradiation. In cases where severely damaged ureters forbid connection to a normal transverse conduit, we performed a pyelotransverse pyelocolostomy with high anastomosis of the bowe…
Incomplete Conventional Colonoscopy: Magnetic Resonance Colonography in the Evaluation of the Proximal Colon
2005
Background and Study Aims: The purpose of this study was to evaluate dark-lumen magnetic resonance (MR) colonography prospectively in patients with incomplete conventional colonoscopy. Patients and Methods: Thirty-two patients with incomplete conventional colonoscopy underwent same-day dark-lumen MR colonography on the basis of a standard protocol. The depiction of colorectal diseases was assessed in the following colon segments: cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum. The reasons for incomplete colonoscopy included high-grade stenosis in 26 patients (four with occlusive cancer, 12 with fibrotic stenosis based on recurrent sigmoid diverticuliti…
Unexplained neoplastic anastomotic recurrence after right hemicolectomy: a case report
2020
Abstract Background Anastomotic recurrences of the colon are postulated to arise due to inadequate margins, tumor implantation by exfoliated cells, altered biological properties of bowel anastomosis, and missed synchronous lesions. In this paper, a case of unexpected early local recurrence after surgery for colon cancer is presented. Case presentation A 68-year-old Caucasian man underwent right hemicolectomy for invasive G2 adenocarcinoma. Two months later, endoscopy revealed a wide and well-functioning anastomosis with a hyperemic, hard, and thickened mucosal area of about 2 cm in diameter. Biopsies showed the presence of an adenocarcinoma with the same grading of the previous lesion. Ten …
Fecal Blood Loss in Patients With Colonic Polyps: A Comparison of Measurements With 51Chromium-Labeled Erythrocytes and With the Haemoccult Test
1982
Abstract The quantitative determinations of fecal daily blood loss after intravenous administration of 51Cr-labeled erythrocytes in 44 patients with colonic polyps and in 11 controls were compared with the results of the daily performed Haemoccult test without dietary restrictions. A total of 642 stool specimens was analyzed for 51Cr loss and the Haemoccult test. The mean fecal daily blood loss in the 34 patients with adenomatous polyps of the descending colon and rectosigmoid was 1.36 ± 0.14 ml/day (mean ± SEM), in the 10 patients with polyps of the ascending and transverse colon it was 1.28 ± 0.31 ml/day, and in the 11 controls 0.62 ± 0.07 ml/day. There was no positive Haemoccult test in …
Complex long-segment intestinal dysganglionosis.
2000
A case is reported with aganglionosis of the rectum, sigma, and descending colon; dysganglionosis with heterotopic ganglionic cells in the muscularis propria of the hypoganglionic transverse colon; and extreme hypoganglionosis (without detection of ganglionic cells) of the ascending colon and distal ileum. The ileum showed a transition zone with hypoganglionosis and intestinal neuronal dysplasia (IND) type B. As to the etiology of such complex intestinal innervation defects, pre- and perinatal perfusion deficits must be considered because their localization seems to be linked to the vascular anatomy of the colon. Early diagnosis may be difficult, causing a delay in operative treatment and m…
Aussagefähigkeit der Abdomenübersichtsaufnahme in der Differenzierung der Rotavirus-negativen und Rotavirus-positiven nekrotisierenden Enterokolitis
1991
Clinical data and radiographic findings of 32 newborn suffering from necrotising enterocolitis were analysed [12 patients with rotavirus-positive necrotising enterocolitis (RV + NEC), 20 patients with rotavirus-negative necrotising enterocolitis (RV-NEC)]. The presence and degree of pneumatosis intestinalis, portal venous gas and pneumoperitoneum on abdominal radiographs were graded after Kosloske et al. according to "mild, moderate, and severe". Pneumatosis intestinalis occurred twice as often in the ascending colon in RV-NEC compared to RV + NEC, whereas the transverse colon was involved nearly as frequently as the descending colon in both groups. Portal venous gas was present in 10% of t…
Endometriose des Colon transversum
2002
HISTORY A 65-year-old woman with no complaints came to our hospital for a colonoscopy because of a family history of a colorectal carcinoma. Because of postmenopausal complaints she had been undergoing estrogen therapy for the past five years. INVESTIGATIONS Colonoscopy revealed a 2 x 2 cm polyp like structure with central tissue proliferation in the transverse colon. Neither chromoendoscopy with indigocarmine nor multiple biopsies indicated an adenomatous glandular proliferation. Miniendosonography revealed the image of a tumour located in the muscularis propria. DIAGNOSIS AND CLINICAL COURSE: As a malign process could not definitely be excluded, a colon segment resection was carried out b…
