Gaddy T Bergmann
BACKGROUND: Diversity and composition of microbial communities was compared across the 13 major sections of the digestive tract (esophagus, reticulum, rumen, omasum, abomasum, duodenum, jejunum, ileum, cecum, ascending colon, transverse colon, descending colon, and rectum) in two captive populations of American bison (Bison bison), one of which was finished on forage, the other on grain. RESULTS: Microbial diversity fell to its lowest levels in the small intestine, with Bacteroidetes reaching their lowest relative abundance in that region, while Firmicutes and Euryarchaeota attained their highest relative abundances there...

REVIEW
B Jansen-Winkeln, O Lyros, A Lachky, N Teich, I Gockel
Laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) constitutes a curative treatment option for therapy-refractory ulcerative colitis. A two-stage procedure with loop ileostomy at the time of IPAA is the most frequent variant of surgery. The aim of the procedure is the complete removal of the colon and rectum with simultaneous restoration of gastrointestinal continuity and preservation of continence functions. Long-term quality of life following laparoscopic proctocolectomy with IPAA is good and comparable with a healthy reference population...

Upper Gastrointestinal (GI) pseudomelanosis is an uncommon entity characterized by endoscopic visualization of speckled dark mucosal pigmentation. While described in the rectum and colon, 'melanosis' or more aptly 'pseudomelanosis' is rare in the duodenum and exceedingly rare in the stomach. Five cases of pseudomelanosis were encountered at our department. Four females and one male were diagnosed, with a mean age of 70 years. All patients exhibited duodenal pseudomelanosis, with one demonstrating gastric antral pseudomelanosis as well...

PURPOSE: Titanium ring cap applicator (VariSource) was applied in treating cervical cancer patients by using image-guided brachytherapy (IGBT). However, its sizes appeared to be relatively large for most of our patients. Thus, we have developed a specific applicator "Siriraj Ring Cap," which is slightly smaller and more suitable for our patients. This study was to evaluate effectiveness of this equipment. METHODS AND MATERIALS: Locally advanced cervical cancer patients were treated with external beam radiation therapy with or without concomitant chemotherapy...

Neuroendocrine cells often coexist with exocrine neoplasms of the gut and each component is normally present in a variable range. Despite this frequent association, mixed exocrine-neuroendocrine carcinomas are rare. This entity is known as adenoneuroendocrine carcinoma (MANEC) and each of its malignant components represents at least 30%. In contrast, there are only a few reports of another rare association of an adenoma and a well differentiated neuroendocrine tumor (NET) in the colon and rectum. The term mixed adenoneuroendocrine tumor (MANET) was suggested due to its indolent behavior and distinct morphological characteristics with mild to moderate nuclear atypia and low number of mitoses1...

A 27-year-old female heroin addict presented with a peritonitic and distended abdomen. Her medical history included depression and a 3-year history of heroin abuse with attendant constipation. CT scan showed free intraperitoneal gas, massive faecal distension of the rectum and sigmoid colon and likely bowel necrosis. She underwent an emergency Hartmann's procedure for perforation of the sigmoid colon. Pathology identified two areas of stercoral ulceration, one of them being the area of perforation. Postoperatively, the patient developed a deep vein thrombosis and is now on anticoagulant therapy...

BACKGROUND AND AIMS: Primary sclerosing cholangitis (PSC) patients with ulcerative colitis (UC) have a high risk of colonic neoplasia. As histologic inflammation is an independent risk factor for the development of neoplasia, we hypothesized that patients with UC and PSC have more subclinical disease activity than patients with UC alone. METHODS: We performed a retrospective evaluation of patients with ulcerative pancolitis who were in clinical remission and compared endoscopic and histologic activity between those with and without PSC...

PURPOSE: To provide a fast computational method, based on the proximal graph solver (POGS) - a convex optimization solver using the alternating direction method of multipliers (ADMM), for calculating an optimal treatment plan in rotating shield brachytherapy (RSBT). RSBT treatment planning has more degrees of freedom than conventional high-dose-rate brachytherapy due to the addition of emission direction, and this necessitates a fast optimization technique to enable clinical usage. METHODS: The multi-helix RSBT (H-RSBT) delivery technique(1) was investigated for five representative cervical cancer patients...

BACKGROUND: Increased defecation frequency and soiling are common complications of surgery for right-sided Hirschsprung's disease (HD). Though the laparoscopic Duhamel procedure is a favorable option in right-sided HD, the conventional laparoscopic technique is time consuming and has complications that are associated with the reservoir. In this study, we described a modified laparoscopic Duhamel technique with ex-anal rectal transection combined with the Deloyer's procedure for right-sided HD...
