Multiple synchronous adenocarcinomas of the small bowel in a young patient: A case report.

INTRODUCTION: Adenocarcinoma of the small bowel is a rare neoplasm presented usually in elder patients as a single tumor. Its presentation as multiple tumors and in young patients is exceptional and there aren't any guidelines to orient its therapy. PRESENTATION OF CASE: We present the rare case of a sixteen-year-old woman that presents to the emergency department with an intussusception due to a small bowel tumor. The resected specimen showed multiple adenocarcinomas. A complete endoscopic and PET-CT study showed other 5 lesions from the duodenum to the ileum that were resected. Genetic counseling showed no pathogenic changes. The final staging was T2N0M0 and only surveillance was indicated. The patient is now 3 years without any recurrence. DISCUSSION: Multiple adenocarcinomas of the small bowel are a very infrequent presentation of the disease. Most common risk factors include Crohn disease and adenomas. Its presentation is usually vague with a delay in its diagnosis. The treatment remains mainly surgical with limited use of adjuvant therapy. The most important prognostic factor is lymph node involvement with 5-year survival that can range from 3%-60% depending on the stage. CONCLUSION: This case represents an exceptional presentation of a very rare pathology with few cases described in the literature. There isn't one single best study to stage the patient and surgery is still the standard of treatment while adjuvant therapies studies are being conducted. The young age and lack of predisposing factors or mutations leaves an open field for investigation.

[Liver transplantation in adults: a caseload from Clínica Alemana de Santiago, Chile]. / Trasplante hepático en adultos: casuística de Clínica Alemana de Santiago.

BACKGROUND: The success of orthotopic liver transplantation (OLT) has resulted in its widespread use for different liver diseases. AIM: To report our 8 years experience with adult OLT at Clinica Alemana de Santiago. PATIENTS AND METHODS: In all transplantations done at the center, we recorded patient's overall data and survival, postoperative medical and surgical complications and causes of death. RESULTS: Between November 1993 and September 2001, 51 consecutive OLT were performed in 44 patients (22 females, median age 45 years old). Thirty eight patients presented with chronic and 6 with acute or sub-acute liver failure. Cryptogenic cirrhosis and hepatitis C infection were the most common causes for OLT. Postoperative bleeding and extrahepatic biliary complications were seen in 17.6 and 21.5% of cases respectively. Acute rejection, bacterial infections, CMV infection or disease and post OLT hemodialysis were the most common medical complications (51, 31, 19.6 and 19.6% of cases respectively). The overall 1 and 5 years survival rates were 80% and 73% respectively. Considering exclusively the last 22 OLT performed since January 1999, the 1 year survival rate has improved to 91%. CONCLUSIONS: Liver transplantation in Chile provides a good long term survival with acceptable morbidity, due to a multidisciplinary approach management. The survival rates have improved over the last few years probably due to better surgical techniques, ICU care and immunosuppression. These overall results are comparable with those from other Centers in developed countries.
