Alimentary tract duplications are uncommon congenital abnormalities usually diagnosed and treated in childhood. Rectal involvement is extremely rare. We report the case of a 22-year-old female who presented with chronic abdominal and perianal pain; feeling of rectal fullness. Workup revealed a rectal duplication cyst. The patient underwent a complete transabdominal excision of the cyst: an hybr...

Rectal bleeding is considered to be an alarm symptom of colorectal cancer. However, the symptom is seldom reported to the general practitioner and it is often assumed that patients assign the rectal bleeding to benign conditions. The aims of this questionnaire study were to examine whether rectal bleeding was associated with longer patient delays in colorectal cancer patients and whether rectal...

BACKGROUND Relationships between pain threshold during rectal distension and both symptoms intensity and alteration in quality of life (QoL) in irritable bowel syndrome (IBS) patients have been poorly evaluated. AIM To evaluate relationships between rectal sensitivity, IBS symptom intensity and QoL in a multicentre prospective study. METHODS Rectal threshold for moderate pain was measured d...

Rectal adenomas and cancers occur frequently. Small adenomas can be removed colonoscopically, whereas larger polyps are removed via conventional transanal excision. Owing to technical difficulties, adenomas of the mid- and upper rectum require radical resection. Transanal endoscopic microsurgery (TEM) was first designed as an alternative treatment for these lesions. However, since its developme...

A system has been established for continuous recording of rectal and body surface temperatures in conscious, chair-restrained rhesus macaques. Diurnal changes in rectal temperature and body surface temperatures of head, back, abdomen, and inner thigh were recorded for 24 hours under conditions of intermittent or constant light. When lights were on for 8 hours (0800 to 1600 hours) and off for 16...

PURPOSE Restaging after neoadjuvant treatment is done for planning the surgical approach and, increasingly, to determine whether additional therapy or resection can be avoided for selected patients. MATERIALS AND METHODS Local restaging after neoadjuvant chemoradiation therapy (nCRT) was performed in 270 patients with locally advanced (cT3or4 or N+) rectal cancer. Abdomen and pelvic computed ...

INTRODUCTION High rectal doses are associated with increased toxicity. A rectal displacement device (RDD) reduces rectal dose in prostate stereotactic body radiation therapy (SBRT). This study investigates any dosimetric difference between two methods of rectal displacement (Rectafix and SpaceOAR) for prostate SBRT. METHODS Rectal dosimetry of 45 men who received SBRT within the PROMETHEUS tr...

RATIONALE Rectal neuroendocrine tumor (NET) is a relatively rare tumor. Well-differentiated NETs (G1 and G2) rarely display distant metastasis at initial diagnosis. Currently, treatment for the primary lesions of rectal NETs with liver metastasis remains controversial. The liver metastasis was resected in local hospital. Transanal endoscopic microsurgery (TEM) has emerged as an effective minima...

A 45 years female presented with a complain of something coming out through her anus since one year, which comes on straining and reduces only after manual intervention. She had also, a history of constipation with occasional blood and mucus discharge in the stool. On examination, she was found to have full thickness rectal prolapse, which comes out on straining and reduces only after pushing i...

In order to relieve mechanical obstruction caused by rectal carcinoma, a bare rectal stent was inserted in the sigmoid colon of a 70-year-old female. The procedure was successful, and for one month the patient made good progress. She then complained of abdominal pain, however, and plain radiographs of the chest and abdomen revealed the presence of free gas in the subdiaphragmatic area. Surgical...
