Deep-infiltrating endometriosis may affect the vagina, the rectum, and the cervicoisthmic part of the uterus, resulting in severe pain, particularly dyschezia, dysmenorrhea, dyspareunia, and diminished quality of life. Advanced surgical techniques, such as laparoscopic-assisted anterior rectum resection, are recognized as safe and effective therapeutic approaches. In some cases, a laparotomy or...

BACKGROUND We aimed to explore the efficacy and safety profile of preoperative neoadjuvant chemoradiation (NACRT) in locally advanced rectal cancer (LARC) in upper rectum versus middle/lower rectum. METHODS The study included 173 patients with stage II or III (T2-4b, N0-2b) LARC who underwent NACRT followed by total mesorectal excision (TME) between January 2011 and October 2016. Cox regressi...

PURPOSE To develop and evaluate the clinical applicability of advanced machine learning models that simultaneously predict multiple optimization objective function weights from patient geometry for intensity-modulated radiation therapy of prostate cancer. METHODS A previously developed inverse optimization method was applied retrospectively to determine optimal objective function weights for ...

The electric activity of the sigmoid colon (electrosigmoidogram=ESG) and rectum (electrorectogram=ERG) and their relationship was studied in nine patients. Slow waves or pacesetter potentials (PPs) of the sigmoid colon and rectum were recorded. The PP frequency and amplitude of the electrorectograms were higher (p less than 0.05) than electrosigmoidograms. Balloon distention of the sigmoid colo...

Carcinoid tumors of the rectum are uncommon tumors [1]. However, recent report shows that the number of reported cases increases rapidly in both Japanese and non-Japanese series [2], probably due to the constant increase number of colonoscopic examination. The rectum is the most common site of gastrointestinal carcinoid tumors in Japan and the third most common site in American-European countri...

A second exploratory laparotomy in our unit revealed duplication of entire colon up to the lower rectum. The terminal ileum was seen to enter the normal large bowel and the three parallel appendices were attached to the duplication, which was on the anterior side. We found that the duplication did not communicate with the normal bowel at the distal end by injecting saline into its distal end wh...

BACKGROUND Synchronous early primary cancers are rare and in addition synchronous adenocarcinoma of both rectum and gallbladder is extremely rare. CASE REPORT We report an unusual case of synchronous early primary adenocarcinoma of rectum and gallbladder. The patient was a 72-year-old woman with complaints of bloody stools and constipation. An endoscopy revealed adenocarcinoma of the lower re...

An increased incidence of carcinoma of the small bowel and colon has been described in patients with Crohn's disease. Tumours arising in the rectum and anus are reported less often. Between 1940 and 1992, of some 2500 patients with Crohn's disease seen at this hospital, 15 are known to have developed carcinoma of the lower gastrointestinal tract. Malignancy occurred in the colon in two patients...
