Abstract:

Sonography plays a primary role in the diagnosis of gynecological diseases. A retrospective review of incidental findings report by transvaginal sonography (TVS) was performed to evaluate the ability of TVS to visualize rectosigmoid carcinoma. The authors performed a retrospective review of 450 women who were referred for TVS because of suspected gynecological indications to evaluate those with incidental findings. Of these, 15 with incidental findings were subsequently diagnosed with rectosigmoid carcinoma. The sonographic properties and clinical findings were systematically evaluated. TVS findings included solid nonhomogeneous lesions (mean diameter of 4 cm; range, 1.6–8 cm), distended rectal walls, and gas inside the gastrointestinal lumen in 53% ( n = 8) of the cases. Total wall invasion was suspected, and signs of edema were noticed in 60% ( n = 9) of the cases. All lesions seen by TVS were pathologically confirmed as carcinoma of gastrointestinal origin. Inspection of the rectosigmoid during a TVS examination has the ability to detect unsuspected rectosigmoid lesions.

Abstract:

We describe a rare case of invasive endometrioid adenocarcinoma arising from uterine adenomyosis involving the rectosigmoid colon. At laparotomy the uterus was densely adherent to the rectosigmoid colon. The final pathologic study of surgical specimens revealed intact endometrium and endometrioid adenocarcinoma scattered diffusely throughout the posterior myometrium with direct invasion into the rectosigmoid colon. There were numerous adenomyotic foci around the carcinoma. This case emphasizes the fact that biopsy findings from a uterus with adenocarcinoma arising from adenomyosis can be false negative. Physicians should keep in mind the possible existence of malignancies arising from adenomyosis when uterine malignancies are clinically suspected but histologic evaluation fails to confirm the diagnosis.

Abstract:

Differentiation between rectal and sigmoid carcinomas is a diagnostic challenge with important implications for further treatment. Depending on the tumor stage, treatment for rectal carcinoma consists of preoperative (chemo)radiotherapy and surgery. Sigmoid carcinomas are treated with surgery alone. We established the diagnostic accuracy of flexible endoscopy, MRI and/or CT scan, and both modalities combined as reflected by the conclusion of our multidisciplinary team (MDT). Furthermore, we assessed the treatment consequences of misdiagnosis. Consecutive patients were included who underwent surgery from January 2012 to January 2017 for colorectal carcinoma located ≤20 cm from the anal verge as determined by flexible colonoscopy. Diagnostic accuracy of MRI/CT, flexible endoscopy and the final MDT conclusion were analyzed as index test. The location of the tumor during surgery and the type of surgery was the reference standard. We included 293 patients. Flexible endoscopy had a diagnostic accuracy of 90% and for MRI/CT scanning this was 86–87%. Combination of both modalities improved diagnostic accuracy to 96%. Due to misdiagnosis during initial staging, three patients (1%) erroneously underwent neoadjuvant treatment and in two patients neoadjuvant treatment was potentially erroneously omitted. In conclusion, the combination of both flexible endoscopy and MRI/CT (the MDT conclusion) improves diagnostic accuracy. Erroneous clinical diagnosis can lead to under- and overtreatment.

Abstract:

A 34-year-old man with recent-onset constipation presented with colonic obstruction due to a palpable rectal tumour. Colostomy relieved the obstruction and biopsy revealed carcinoma. During workup, full-thickness rectal prolapse occurred with the tumour at the apex of an intussusception. Imaging revealed a low rectal tumour and no metastases. An abdominal oncological rather than perineal resection of the rectum was planned. At laparotomy, the tumour was reduced and was seen to originate at the rectosigmoid junction. Surgery was successful and follow-up has been clear. Histology revealed an adenocarcinoma with microsatellite instability. Rectal prolapse due to tumour intussusception is very rare. In this young man, it was due to straining at stool because of constipation and tenesmus rather than pelvic floor abnormality. An associated colorectal tumour should be considered in patients with rectal prolapse. In such cases, surgical and adjuvant management may need to be modified.

Abstract:

Adenosquamous carcinoma of the colon is rare. A paraneoplastic syndrome presenting as hypercalcemia may occasionally occur in association with these tumors. Survival for more advanced stages of disease is lower than for patients with adenocarcinoma at a corresponding stage. We report a patient who presented with a primary adenosquamous carcinoma of the rectosigmoid junction and we review the literature regarding the clinical presentation, management, and prognosis of this tumor.

Background： Colorectal cancer is the leading cause of cancer incidence in Taiwan. The aim of this study was to compare the short-term outcome between laparoscopic versus and open resection of colorectal cancer patients. Study design： From Jan. 2009 to Mar.2012, patients were pathological proved rectosigmoid malignancy with AJCC staging followed by surgical resection under our service. This was a retrospective chart review study. Results： Ninety colorectal cancer patients who with pathologically confirmed primary colorectal cancer were enrolled in this study. Forty-four were underwent laparoscopic colectomy and 46 were underwent open colectomy. There are no difference between demographic data, ex : age, gender, ASA, tumor size and pathological grading in these two groups. Our results showed that laparoscopic group has less post operative complications（3：12，p=0.022）；estimated blood loss（Mean (range) 104.6 (25-800)：441.9 (100-1425)，p<0.01）；and blood transfusion during operation（4：14，p=0.017） compared with open colectomy group. It also has faster post operative recovery like post op tolerance soft diet（definition：try soft diet more than 1000 gm without vomiting）（Median 6,range 4-21）：7,range 5-23，p=0.03）and hospital stay （Median 10, range 9-36：12, range 7-32，p<0.01）. A similar proportion of patients had a minimum of 12 lymph nodes by pathology (95.7%：95.5%, p=0.946). Conclusion： The oncologic outcome between laparoscopic colectomy and open colectomy is similar. However, there are less complications and hospital stay in laparoscopic colectomy group compared with open colectomy.

Abstract:

Introduction: Surgery plays an important role in the management of advanced stage ovarian cancer and is complex involving surgical procedures including peritonectomy, splenectomy, diaphragmatic stripping, retroperitoneal lymph node dissection and bowel resection including resection of recto-sigmoid. Objective: To assess the safety and efficacy of the patients undergoing modified posterior pelvic exenteration and rectosigmoid anastomosis achieving in optimal cytoreduction. Methods: Between June 2011 and June 2014 a total of 100 patients underwent surgical cytoreduction for advanced epithelial ovarian cancer of which 20 patients had undergone modified posterior pelvic exenteration with rectosigmoid anastomosis. The present study includes a retrospective analysis of these 20 patients. Rectosigmoid anastomosis was done using circular stapler in these patients. All patients had a PS score of 1 or 2. Results: The median age of patients was 50 years. The optimal status of no macroscopic residual disease was achieved in all patients. Modified posterior pelvic exenteration with rectosigmoid anastomosis was carried out to achieve optimal status of surgical cytoreduction in 20 patients out of which fifteen patients had primary surgical cytoreduction, three patients had interval surgical cytoreduction surgery after receiving three cycles of neoadjuvant chemotherapy with paclitaxel & carboplatin while two patients had this procedure as a part of secondary surgical cytoreduction. The most common histology was papillary serous carcinoma. Average blood loss was 500 ml. Mean operative time was 6 hours. There were no intra operative complications. Bowel movements returned to normal in 3 to 5 days. The median length of hospital stay was 7 days. The median time to start postoperative chemotherapy was 32 days. There was no major morbidity and mortality. Conclusion: Modified posterior pelvic exenteration with rectosigmoid anastomosis should be performed when indicated as a part of cytoreduction. In our experience this is a safe and effective procedure to achieve optimal status in advanced ovarian cancer.
