Surgical management of colorectal cancer for the aging population—A survey by the Japanese Society for Cancer of Colon and Rectum

OBJECTIVE The treatment policy of colorectal cancer in elderly patients is controversial due to a lack of specific guidelines. To clarify the present management of colorectal cancer for aged patients, a questionnaire survey was conducted by the Japanese Society for Cancer of the Colon and Rectum. METHODS Questionnaire forms were sent to the 430 member institutions of the Japanese Society for Cancer of the Colon and Rectum. RESULTS The response rate of the surgical department to the questionnaire was 39%. Performance status was used for preoperative assessments, and electrocardiogram and ultrasonic cardiograms were conducted for cardiovascular evaluations in many institutions. The same extent of surgical procedures was often adopted for elderly and younger patients, and the frequency of a laparoscopic procedure was the same regardless of a patients age. A simultaneous hepatectomy for hepatic metastasis was considered in one-third of institutions. In many institutions, intersphincteric resection for patients with possible sphincter-saving surgery was not considered for elderly patients with low rectal cancer. CONCLUSION Japanese Society for Cancer of the Colon and Rectum member institutions often used the same surgical treatment strategies for both elderly and younger patients with the exception of performing intersphincteric resection.

Successful repair of a rectovaginal fistula caused by a tension-free vaginal mesh (TVM): a case report

Rectovaginal fistula caused by a tension-free vaginal mesh (TVM) is a rare condition. Moreover, a rectovaginal fistula is a challenging issue to address for surgeons regardless of causes. Due to a low rate of occurrence, treatment modality for a rectovaginal fistula caused by a TVM has previously received little attention. A successful surgery using several key techniques to address a rectovaginal fistula caused by a TVM is herein reported. A 78-year-old woman who underwent a TVM for a rectocele three months ago was referred to our hospital with a two-month history of anal bleeding. Mesh protruding into both the vagina and the rectum was confirmed. The patient was operated on under diagnosis of a rectovaginal fistula caused by TVM. TVM was removed by transvaginal dissection of the rectovaginal septum with division of both anterior and posterior arms of the TVM. Layer-to-layer sutures of rectal and vaginal walls were crossly performed with a drain placed in the rectovaginal septum after saline irrigation followed by a covering sigmoid colostomy. The wound healed without infection after surgery, and a water-soluble contrast enema demonstrated the healing of the rectovaginal fistula two months after surgery. No recurrent fistula was confirmed 15 months after stoma closure.

Clinical Significance of Serum Carcinoembryonic Antigen and Carbohydrate Antigen 19-9 Levels before Surgery and during Postoperative Follow-up in Colorectal Cancer

Objective: Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most common colorectal cancer markers. We aimed to identify the appropriate clinical conditions for measurin...
