[Monofilaments in digestive system surgery].

The most important physical and chemical properties of the new synthetic absorbable suture materials are shown. Particularly this paper make a comparison between multifilament and monofilament suture wire from the point of view of tensile strength, "in vivo" tensile strength retention, reabsorbability, foreseeability of the reabsorption time of the capillarity. On these theoretical basis the AA. think that actually the best suture wire for the gastrointestinal surgery must be a synthetic absorbable monofilament suture material. Clinical and experimental experience of the AA. utilizing in the surgery of the gastrointestinal tract a copolymer monofilament of the glycolic acid and of the trimethylene carbonate (polyglyconate-Maxon), resorbable by not-enzymatic hydrolysis in about 180 days are described. The clinical experience was acquired performing 43 manual gastroenteric anastomosis by polyglyconate suture material and making an endoscopic follow-up in 19 cases (12 oesophago-jejunal anastomoses and 7 colo-rectal anastomoses). The experimental study consist of 30 enteric anastomosis performed on rats. The results evaluation was made from three points of views: bacteriological, optical diffuse light microscopy and electronic transmission microscopy. The conclusions of the clinical and experimental studies are favourable for the use the polyglyconate suture wire in digestive surgery, and confirm also "in vivo" its theoretical properties.

Simultaneous pancreas kidney transplantation: initial experience of the Emory University transplant service.

The successful replacement of islet tissue by pancreas transplantation appears to be beneficial in the early course of those uremic diabetic recipients who receive a simultaneous renal transplant. The long-term advantages of SKP transplantation remain to be determined, however, current improvement in patient and graft survival following SPK and the difficulties thus far reported in islet cell transplantation have renewed clinical interests in SPK, PAK and PA transplantation. In our experience, pancreas transplantation has been a challenging technical, immunological and physiological endeavor which was well received by our patients despite the initial problems and complications we and they encountered. Notwithstanding extensive preparation, our team experienced a "learning curve" and we present many of the lessons we learned. This knowledge has aided our transplant team in the successful management and avoidance of these complications and other inherent problems associated with SKP transplantation in subsequent patients.

[Ultrasonography-guided percutaneous needle biopsy with large needle versus surgical biopsy in the diagnosis of breast lesions].

The authors report their experience on percutaneous large core biopsy with standard needle in the diagnosis of breast lesions. This method, that has the same advantages of open biopsy, allows a better cytological examination, prevent sequelae of surgery and lower costs.

Primary lymphoma of the liver: a case report and review of the literature.

Primary lymphoma of the liver (PLL) is a rare disease and estimation of the real number of cases may be difficult because strict diagnostic criteria for the definition of a primary lesion are quite often not followed. We report here on a case of a patient affected by PLL who underwent successful surgical resection of the lesion followed by chemotherapy and autologous bone marrow transplantation. The patient is alive and disease free 62 months after resection.
