In the present study, ionizing radiation (IR)-induced bystander effects were investigated in two lung cancer cell lines. A549 cells were found to be more resistant to radiation-conditioned medium (RCM) obtained from A549 cells when compared with the H460 exposed to RCM procured from H460 cells.

Purpose: Roux-en-Y biliojejunostomy has been frequently used in the management of benign biliary disease. The aim of this study was to summarize one institute’s experiences in prevention and management of subsequent complications of Roux-en-Y biliojejunostomy. Methods: A retrospective analysis was carried out for patients who underwent reoperation after Roux-en-Y biliojejunostomy from February 1990 through June 2004. Operation history, laboratory test data before the last operation, and images were collected. Results: Sixty-one patients, aged 36–60 years and with a 3.5-year average operation interval, were involved in the study. Anastomotic stricture (47, 80.3%), recurrent calculi (36, 60.7%), and biliary tract infection (all) were the most common complications after Roux-en-Y biliojejunostomy. Other complications (such as calculi of the intrahepatic duct or intrahepatic duct stricture, malformed or twisted jejunum loop, too long or too short proximal jejunum, disappearance of the normal form of anastomosis, and adhesion of the intestinal loop) were also detected by laparotomy. Conclusion: Calculus, stricture, and infection arise as a result of each other. Lessening of the anastomotic stricture, fluent drainage of the distal jejunum below the anastomosis, and relieving pressure of gastrointestinal tract are pivotal in decreasing subsequent complications after Roux-en-Y biliojejunostomy.

With pelvic reconstructive surgery becoming more commonplace, knowledge of possible anomalous vessels is important because modification of planned surgical approach may be necessary to avoid short-term and long-term complications.

A 66-year-old female presented with symptoms suggestive of pelvic organ prolapse, history of fibroid uterus, and rectal pressure. Pelvic examination revealed a large pelvic mass filling the posterior cul-de-sac, occupying the rectovaginal septum, and compressing the rectum. There was a stage II pelvic organ prolapse of the posterior vaginal wall with distal vaginal wall extending to the hymen during valsalva. A CT scan confirmed the large pelvic mass distinct from the uterus measuring 9.4 × 9.8 × 6.2 cm. Colorectal workup revealed adenocarcinoma of colon on screening colonoscopy with biopsies. Patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy, colon resection, and abdominal resection of the pelvic mass in the rectovaginal septum and inferior to the uterus. The patient did not require any concomitant pelvic reconstruction and the posterior vaginal wall prolapse resolved after resecting the pelvic mass.
