A description of the examination of the rectum falls naturally into two parts: (I) Examination of the rectum itself; (II) Examination of the pelvis and, under certain conditions, of some abdominal organs through the wall of or from within the lumen of the rectum. The latter should always be made to include the former, and no examination of the rectum per se can be considered adequate unless it ...

Chronic constipation is a disorder frequently encountered in clinical practice. Here, we describe the use of ultrasonography as a new approach to the follow-up of adult patients with functional chronic constipation. Specifically, we report two cases of functional chronic constipation: fecal retention in the rectum and not fecal retention in the rectum. In the not fecal retention in the rectum p...

Giant gastrointestinal stromal tumors (GISTs) of the rectum are rare and often difficult to remove surgically. At the time metastases are found, GISTs are considered to be incurable and until recently no adequate therapy was of any value for these patients. Recently, imatinib was introduced: a signal transducing inhibitor acting specifically on the KIT-tyrosine kinase, which can be used to down...

INTRODUCTION The interesting topic of cutaneous and subcutaneous metastasis from rectal carcinoma is discussed using 3 cases. CLINICAL PICTURE The first case was a 70-year-old man with T3N2M0 rectal mucinous adenocarcinoma, who developed an inflammatory subcutaneous metastasis at the left scapula 2 years after anterior resection. The second case was a 51-year-old man with T4N2M0 splenic flexu...

Colorectal masses can be non-neoplasm, benign neoplasm and malignant neoplasm. Diagnosis of colorectal mass done by biopsy or surgery then followed histopathological examination. The aim this study was to described the histopathology feature in Anatomic Pathology Laboratory Arifin Achmad Regional Hospital Riau Province January 2015 - December 2019. This found 304 cases consisted men (55,6%) wom...

background: this study assessed the optimal timing of computed tomography for detection of metastatic disease in locoregional lymph nodes in patients with rectal cancer who have undergone chemoradiotherapy. materials and methods: this observational retrospective study was performed in a single institution. all patients with locally advanced rectal cancer treated with chemoradiotherapy, followed...

A solid pseudopapillary tumor of the pancreas (SPT) is alternatively called a 'Frantz tumor.' It was first named after its discoverer in year 1959. This has been previously designated as papillary epithelial neoplasm, low-grade and neoplasm pancreas. rare pancreatic neoplasm. typically affects young people female predilection. Its histogenesis rather debatable. Acinar, endocrine, ductal...

PURPOSE A major concern in prostate brachytherapy is rectal toxicity, which mainly depends on the dose and volume of rectum involved by radiation. We hypothesize that the rectal distension, as produced by constipation, influences the dosimetric parameters of the rectum and other pelvic organs. MATERIAL AND METHODS An open, controlled, prospective, paired trial (pre-post test) was designed and...

BACKGROUND The aim of this study was to analyze the influence of volumetric changes of bladder and rectum filling on the 3D dose distribution in prostate cancer radiotherapy. METHODS A total of 314 cone-beam CT (CBCT) image data sets from 19 patients were enrolled in this study. For each CBCT, the bladder and rectum were contoured and volume sizes were normalized to those on their original CT...

PURPOSE Most well-differentiated neuroendocrine tumors (WD-NET) of the enteropancreatic system are low-intermediate grade (G1, G2). Elevated proliferation demonstrated by either a brisk mitotic rate (>20/10 high power fields) or high Ki-67 index (>20%) defines a group of aggressive neoplasms designated as high-grade (G3) neuroendocrine carcinoma (NEC). High-grade NEC is equated with poorly diff...
