[A case of perforated small bowel adenocarcinoma as first symptom of Crohn's disease].

A case of perforated small bowel adenocarcinoma presenting as first symptom of Crohn's disease is reported in a 53 years old male patient with abdominal pain and alteration of bowel habits. Endoscopic bioptical sampling demonstrated a Crohn's disease in active stage. The patient underwent medical therapy with resolution of the complained symptomatology; 20 days after discharge the patients is rehospitalized for acute abdomen. A narrowing perforated neoplasia in terminal ileum was discovered at laparotomy. Diffuse peritonitis and metastatic peritoneal implantations were also revealed. An ileocolic resection is performed with ileo-transverse colon anastomosis. The patient dies 4 months later for advanced disease.

Sequential liver-kidney transplantation.

The indications for sequential liver and kidney transplantation have not been well defined. Two categories of patients may benefit from this procedure: patients with primary renal disease associated with hepatic disorders (glomerulonephritis, tubulointerstitial nephritis, metabolic diseases, and structural diseases) and patients who develop renal failure after liver transplantation. Chronic renal failure is a frequent long-term complication after liver transplantation. End-stage renal disease develops in 2% to 10% of cases by 10 years after transplantation. Kidney transplantation appears to be a better option than dialysis for the treatment of end-stage renal disease after liver transplantation. In contrast, survival rates, after kidney transplantation are significantly lower among liver transplant patients than primary-only kidney transplant recipients. Considering the donor shortage, kidney transplantation should be cautiously considered in liver transplantation patients. New immunosuppressive drugs and protocols are needed to reduce chronic renal failure after liver transplantation.

[Pelvic recurrence of rectal cancer: our experience].

Isolated recurrence of rectal carcinoma have been reported from 7% to 33% with a median of 15. Increasing recurrence is associated with increasing Dukes's stage. Patient who have recurrence after a low-anterior resection are more likely to present with non fixed, surgically correctable lesion versus recurrences after abdominoperineal resection. The most common symptom related to pelvic recurrence is pain, which may be perineal or radiate to the lower extremities. The diagnosis of a locally recurrent rectal cancer was obtained with CT; imaging is the first step to estimate the extent and location of the local tumor growth and the presence or absence of distant metastases. The most common location is at or around the anastomosis and the presacral region. Apart from distant metastases locoregional recurrence is the most important factor determining prognosis and survival. If an R0 resection can be performed, a 5-year survival rate of 20-30% can be achieved. Local or locoregional recurrence implies the reappearance of carcinoma after an intended complete removal of the tumor. For rectal cancer, the adjacent organs include the perineum, bladder and vagina, and LR failure includes perineal or pelvic lesions. Total pelvic exenteration is performed in patients with local recurrence of rectal cancer and a 5-year suvival rate of 30-40% was achieved. For patient with unresectable recurrence, chemotherapy and radiation contribute to a better quality of life and prolong survival. While radiotherapy may reduce recurrence, it is now apparent that total mesorectal excision is the most effective modality, with rates as low as 5%. The anastomotic recurrence that can be locally resected, the best approach for long-term survival is an extensive surgical procedure requiring en bloc removal of adjacent organs and pelvic structures so called composite resection. Intraoperative radiotherapy and brachytherapy, and/or preoperative chemoradiation may provide better results in future. While radioterapy remains the most common antineoplastic modality used for palliation of symptoms, surgical resection remains the mainstay of curative treatment for carcinoma of colon and rectum.
