A rectal metastasis of an unknown lobular breast carcinoma and its management.

Breast cancer is the most common cancer in women but gastro- intestinal metastases of breast cancer are rare. They can occur years after the diagnosis or at the diagnosis of breast cancer. We report the case of a patient complaining of dyschesia, tenesmus and anal incontinence leading to the discovery of a rectal metastasis of an unknown breast neoplasia. Given the oligo-metastatic condition, multidisciplinary and aggressive management was the chosen therapy.

Elective colorectal surgery without bowel preparation: a historical control and case-matched study.

BACKGROUND: Although full bowel preparation, including mechanical washout and non-absorbable antibiotherapy, has been considered for decades as a prerequisite to any elective colorectal surgery, recent literature has suggested that this habit was perhaps unjustified. The aim of this study was to assess the safety of ileocolic, colocolic and colorectal anastomosis in the absence of pre-operative mechanical bowel preparation. METHODS: During a 1-year period, 59 consecutive patients underwent elective colorectal surgery with ileocolic, colocolic or colorectal anastomosis without any pre-operative preparation. This "non-prepared group" (NPG) was compared to a "control group" (CG) composed of the previous 127 consecutive cases of classically managed patients. To improve the statistical power we also compared the NPG to a "match-controlled group" (MCG) of 59 patients within the CG. Primary end-points were anastomotic leakage and abdominal infections. Secondary end-points were oral diet resume time and hospital stay. RESULTS: There were no differences between the 3 groups for age, gender, BMI, immunodepression status, anastomosis site and suture technique. There were no differences between NPG and CG or MCG for anastomotic leakage (3.5%, 4.7% and 6.8% respectively, NPG/CG p = 0.68 and NPG/MCG p = 0.4) or for infectious abdominal complications. Mean diet resume time was 1.4 (1-5) days in the NPG versus 3.4 (1-19) days in the CG and 3.1 (1-6) days in the MCG (p < 0.00001). Median length of postoperative hospital stay was 5 (2-81) days in the NPG versus 8 (4-100) and 8 (4-100) in the CG and the MCG respectively. CONCLUSIONS: In accordance with the recent literature, the present experience does not show any benefit of mechanical bowel preparation in elective colorectal resection. This suggests that bowel preparation could be omitted before this type of surgery.

Tailgut cyst associated with a carcinoid tumor: case report and review of the literature.

We report the case of a 49-year-old woman who presented a tailgut cyst lined by a variety of epithelium including squamous, columnar and transitional. Fortuitously a microscopic carcinoid tumor expressing immunohistochemically neuroendocrine markers was identified in the cystic wall. Tailgut cysts are congenital abnormalities located in the presacrococcygeal area occurring usually in adult patients. Clinical diagnosis is difficult because they are often asymptomatic. Patients may present symptoms resulting from local mass effects or complications. The differential diagnoses include rectal duplication cysts, cystic sacrococcygeal teratomas, epidermal cysts, epidermoid cysts, anal duct or gland cysts. Magnetic resonance imaging has recently become the modality of choice to image the cyst. Malignant transformation is rare; 23 cases including 10 carcinoid tumors have been reported in the literature. To our knowledge, this is the eleventh case of carcinoid tumor arising in a tailgut cyst.

Popliteal artery pseudo-aneurysm and hereditary multiple exostoses.

We describe a rare case of a 21-year-old man presenting with hereditary multiple exostosis and a pseudoaneurysm of the popliteal artery caused by femoral osteochondroma. Principles of management and surgical technique are discussed.
