RESUMO

BACKGROUND: Hepatoid carcinomas (HCs) are extrahepatic neoplasms exhibiting features of hepatocellular tumors in terms of morphology and immunohistochemistry. They have been described in several organs, most notably in the stomach and ovary. They can present in pure forms or in association with other morphological aspects, such as endocrine tumors or ductal adenocarcinomas. The aim of this review is to describe aspects of hepatoid adenocarcinoma of the pancreas with regard to epidemiology, diagnosis, and treatment. METHODS: The PubMed database was searched for publications addressing hepatoid adenocarcinoma of the pancreas. We have searched for articles including the following keywords: 'pancreatic hepatoid carcinoma', 'ectopic liver cancer' and 'rare pancreas neoplasm' published to date. As references, we used case reports and review articles. RESULTS: Pancreatic forms of HCs are extremely uncommon: only 22 cases have been reported. CONCLUSIONS: The possibility of an HC of the pancreas should be considered in the differential diagnosis of an uncommon pathological mass of the pancreas. Treatment seems to be related to the association with other neoplasms, tumor extension at the time of diagnosis and the possibility to perform a radical resection. The common embryologic origin of the pancreas and liver, together with peculiar environmental factors, may explain the development of pancreatic HCs.

RESUMO

BACKGROUND: Irradiation of the pelvis in the treatment of cancers will result in ovarian failure unless the ovaries are shielded adequately. To protect the ovaries, an oophoropexy may be performed. Our aim was to evaluate the feasibility, morbidity, and efficacy of laparoscopic ovarian transposition using a simple percutaneous needle technique. METHODS: Fifteen patients (ten with rectal cancer and five with Hodgkin's disease) underwent the new laparoscopic oophoropexy technique. Laparoscopic releasing of the ovary was performed by cutting the utero-ovarian ligament followed by placing the ovaries on the anterior abdominal wall. A percutaneous straight needle was introduced through a 2-mm skin incision at the site of fixation. Repositioning of the ovaries was done on an outpatient basis without the need for readmission to the operating theatre. RESULTS: The technique was effective, reliable, and simple with no morbidities. Repositioning was performed simply in the outpatient clinic. At follow-up, 11 patients had evidence of ovarian function. CONCLUSION: Percutaneous needle transposition of the ovaries is a simple, effective, reliable, and easy-to-perform technique. It has short learning curve and can be done by less experienced laparoscopic surgeons.

RESUMO

This study describes a novel technique for skeletonization and isolation of Glissonean and venous branches during liver surgery using a harmonic scalpel (HS). Hepatic resections with HS were performed with the skeletonization and isolation technique in 50 patients (HS group). Variables evaluated were blood loss, operative time, biliary leak, and morbidity. The results were compared with 50 hepatic resections that were performed using a previously established technique: Cavitron ultrasonic surgical aspirator with electric cautery, ligatures, and hemoclips (NHS group). The HS group had shorter total operative times (285 versus 358 minutes; P = 0.01), less blood loss (389 versus 871 mL; P = 0.034), and less crystalloid infusion (2744 versus 3299 mL; P = 0.027) compared with the NHS group. Postoperative liver function and complication rates were similar when comparing the two groups. These data demonstrate that HS is a simple, easy, and effective instrument for the skeletonization and isolation of vessels during liver transection.
