1/463. Sigmoid colon cancer presenting as complete rectal prolapse: report of a case.

    We describe herein the unusual case of a 76-year-old woman who was diagnosed as having sigmoid colon cancer after presenting with complete rectal prolapse. The rectal prolapse was considered to have been caused by constipation accelerated by the colon cancer. The relationship between colorectal cancer and rectal prolapse has not yet been clarified; however, this case report suggests that rectal prolapse can present as a symptom of colorectal cancer. Thus, patients with a sudden onset of rectal prolapse should be screened for colorectal cancer. ( info)

2/463. Mediastinal lymph node metastasis of colon cancer: report of a case.

    We herein describe a patient with mediastinal lymph node metastases which occurred after both a primary sigmoid colon cancer and metachronous ovarian metastasis had been resected. The most likely route of metastases to the mediastinum in this case is the paravertebral venous plexus probably connected to the ovarian metastasis, or so-called remetastasis. This case illustrates that the mediastinum is thus a possible metastatic site in patients with colon cancer. Surgeons should therefore pay attention to the mediastinum as well as the lung fields when checking chest X-ray films during a follow-up of patients after a resection of colon cancer. ( info)

3/463. Chromosome instability in lymphocytes from two patients affected by three sequential primary cancers: the role of fragile sites.

    The chromosomal aberration rate and the expression of fragile sites induced by aphidicolin were evaluated in metaphase chromosomes obtained from peripheral blood lymphocytes of two untreated patients with multiple primary cancers. Spontaneous aberrations of chromosome number and structure and chromosome fragility were compared with controls with the use of the same methods. Chromosomal aberration rates and expression frequencies of fragile sites were significantly higher in the patients than in normal control subjects. In the patients, all but one structural chromosome aberration involved at least one fragile site. Our results suggest that fragile sites may be unstable regions of the human genome, which might play an important role in the genetic instability associated with cancer predisposition. ( info)

4/463. Transmesenteric hernia after laparoscopic-assisted sigmoid colectomy.

    BACKGROUND AND OBJECTIVES: Laparoscopic-assisted surgery has been applied for a variety of colonic surgery. The objective of this paper is to demonstrate a possible and avoidable complication of laparoscopic colonic surgery. CASE PRESENTATION: A 47-year-old woman underwent gasless laparoscopic-assisted sigmoid colectomy. On the 20th postoperative day, she developed bowel obstruction. decompression with a long tube failed to resolve the bowel obstruction. Open laparotomy was performed. Abdominal exploration revealed a loop of the small bowel incarcerated in the mesenteric defect caused by the previous operation. Adhesiolysis was performed, and the postoperative course was uneventful. DISCUSSION: Despite technical difficulty, complete closure of the mesentery after bowel resection is strongly recommended for prevention of transmesenteric incarcerated hernia after laparoscopic surgery.

5/463. Endoscopic preoperative colonic tattooing: a clinical and surgical complication.

    Endoscopic colonic tattooing is the simplest and most economic technique for identifying small lesions or polypectomy sites during open and laparoscopic surgery. Moreover, it is useful for the endoscopic follow-up of polypectomy sites. india ink is the agent of choice because of its long-lasting stain and the low risk of adverse reaction and toxicity. Very few cases of complications have been reported. We report here the case of a patient in whom colonic tattooing in preparation for surgical resection was followed by clinical complications such as fever and abdominal pain. An abscess-type inflamed pseudotumor was found at laparotomy. Histological examination revealed chronic granulomatous inflammation. ( info)

6/463. Appendicular involvement in perforated sigmoid disease: US and CT findings.

    We describe four patients in whom ultrasound (US) and/or computed tomography (CT) demonstrated a thickened appendix, secondarily enlarged due to perforated sigmoid diverticulitis (n = 2) or carcinoma (n = 2). The underlying pathology was correctly recognized in all cases. Secondary thickening of the appendix due to perforated sigmoid disease provides a potential pitfall mainly on US and may lead to an incorrect diagnosis and thus to unnecessary surgery or a wrong surgical intervention. Although US alone is enough to diagnose periappendicitis and sigmoid disease, combined use of US and CT may improve assessment of its origin and extension. ( info)

7/463. Diaphragma sellae metastasis from colon carcinoma mimicking a meningioma. A case report.

    We describe a rare case of metastatic intra-suprasellar adenocarcinoma from colonic cancer mimicking a meningioma of the "diaphragma sellae". autopsy studies indicate breast and lung carcinoma to be the most frequent primary tumor metastasizing this site, particularly in patients with systemic spread. While diabetes insipidus is reported to be one of the commonest symptoms in these cases, the only clinical manifestation of the tumor in our patient was a bitemporal hemianopia, while the primary tumor remained asymptomatic. In the available literature are reported only two pituitary metastasis from operated colon carcinoma. In both cases the diagnosis of the colon cancer preceded the pituitary operation. The clinico-pathological and neuroradiological aspects of this unusual lesion are analyzed in the light of the relevant literature on the topic focusing on recent MRI acquisitions. ( info)

8/463. Anesthetic management of high-risk cardiac patients undergoing noncardiac surgery under the support of intraaortic balloon pump.

    patients with severely impaired left ventricular function, an uncorrectable coronary artery disease, and a recent myocardial infarction are at high risk of cardiac complications after major noncardiac surgery. We present two patients with extensive three-vessel coronary artery disease who underwent intraperitoneal surgery under the support of intraaortic balloon pump (IABP). In one patient, the IABP was inserted urgently because of the development of chest pain with significant ST depression on arrival in the operating room, and the other patient was managed with prophylactic IABP. There were no intraoperative or postoperative cardiac events in either patient. Thus, IABP should be considered in the perioperative management of patients with severe cardiac diseases. ( info)

9/463. recurrence of sigmoid colon carcinoma in the residual urethra after cystectomy.

    INTRODUCTION: We report a case of recurrence of sigmoid colon cancer in the residual urethra after cysto-prostato-sigmoidectomy. methods/RESULTS: The patient successfully underwent urethrectomy and is currently tumor-free. To our knowledge, this is the first case of recurrence of a non-urothelial malignant tumor in the residual urethra. ( info)

10/463. Neuroendocrine carcinoma of the sigmoid colon: report of a case.

    Neuroendocrine carcinoma of the colon is a rare entity; however, this type of tumor is known for its aggressive progression and poor prognosis. A case of a 56-year-old Japanese male is presented in this report. A huge, child's head-sized tumor was found to have grown extraluminally on the sigmoid colon with multiple liver metastases. The tumor measured 16.5 x 15 x 8.2 cm in size and weighed 1 300 g. The patient died of hepatic failure due to massive liver metastases 6 months after operation. The pathological findings including an electron microscopic analysis were correlated with those of neuroendocrine carcinoma. We reviewed the English literature, and analyzed 94 cases of neuroendocrine carcinoma which had been reported previously. The nomenclature and definition of this disease still remains somewhat unclear, and not a small population of this disease may thus have been misdiagnosed and treated as other less aggressive entities. The necessity to make an accurate differential diagnosis in such cases is thus emphasized. ( info)
