OBJECTIVES The term heterotopia, in pathology, refers to the presence of normal tissues at foreign sites. Gastric heterotopia has been reported anywhere in the gastrointestinal tract. However, the presence of gastric heterotopia in the rectum is very rare. METHODS We, here, report a rare case of a localized 2-cm area of cratered mucosa with heaped-up borders in the rectum of a 51-year-old, as...

Middle rectal artery is one of the important arteries supplying the rectum, along with the superior and inferior rectal arteries. Study of middle rectal artery was undertaken as it is important in surgeries of rectal carcinoma. .For the present study 40 pelvises were procured from the department of Anatomy of Dr. D. Y. Patil Medical College, Pune.Variations were found in the origin of middle re...

Absorption of electrolytes and water from the human rectum was quantified by sequential sampling of physiological solutions instilled into the rectum and by the method of continuous intraluminal perfusion. The absorptive function of the rectum measured by the perfusion technique was also compared with that of the entire large intestine. The rectum did not absorb sodium, chloride, or water from ...

We investigated immunohistochemical differences in the distribution of TRPV1 channels and the contractile effects of capsaicin on smooth muscle in the mouse rectum and distal, transverse, and proximal colon. In the immunohistochemical study, TRPV1 immunoreactivity was found in the mucosa, submucosal, and muscle layers and myenteric plexus. Large numbers of TRPV1-immunoreactive axons were observ...

BACKGROUND Planning the surgical strategy for a gastrointestinal stromal tumor (GIST) at the posterior wall of the lower rectum is difficult, as the procedures for the lower rectum are hampered by poor visualization and may cause anal dysfunction or discomfort. We report a novel procedure to resect a submucosal tumor of the rectum. CASE PRESENTATION A 75-year-old woman presented with metrorrh...

rectovaginal fistula with atresia ani is a congenital condition that affects the anal opening and rectum by the formation of an abnormal connection between the rectum and vagina. this was diagnosed in a domestic short hair kitten. the presenting physical abnormalities included depression, dehydration, partial tail agenesis, anal atresia and a discharge of watery feces from the vaginal opening. ...

Abdominoperineal resection is a standard method of low-rectum carcinoma treatment. It is associated with significant morbidity and mortality rates, which decreased with the development of preoperative diagnostic procedures, new surgical techniques and new surgical instruments. In this article, laparoscopic pelvic peritonization was used after laparoscopic rectum amputation for low-rectum carcin...

This is a case report of a 40 year old lady presenting with gastrointestinal stromal tumor of rectum. Gastrointestinal stromal tumors (GIST) tend to present with higher frequency in the stomach (60-70%) and small bowel (20-25%) while colon and rectum represent rare sites. Gastrointestinal stromal tumors of the rectum represent around 5% of all GISTs and 0.1% of all tumours originating in the re...
