Reconstructive microsurgery of the rabbit oviduct using serosal microsutures and fibrin sealant.

Microsurgical reconstruction of the rabbit oviduct was undertaken utilizing either: A: fibrin sealant in a thick layer applied to two or three serosa microsutures (20 rabbits), B: fibrin sealant only (20 rabbits), and C: microsutures only (20 rabbits). The pregnancy rates and the patency rates of the oviducts showed no significant differences between the three groups. However, the formation of adhesions at the site of reanastomosis was significantly lower and the total duration of surgery significantly shortened when fibrin sealant was employed. It is concluded that fibrin sealant combined with serosa microsutures certainly is the most convenient method in human tubal microsurgery seeing that this method maintains a higher tensil strength at the site of reanastomosis as compared to group B and avoid the risk of mucosal lesions as compared to group C.

[Angiodysplasia of the duodenum with arteriovenous shunts, sub-serosal prevalence and interstitial elastosis; peritonitis and rupture of sub-serous dysplasic vessels and hemoperitoneum. Description of a case and review of the literature].

We present a case report of a 74 year old man, affected by angiodysplasia of the duodenum, which developed in peritonitis and hemoperitoneum. After undergoing two surgical interventions, it is 14 days since he died. First of all, the importance of this case is due to the extreme rarity of the angiodysplasia of the duodenum, specially when it becomes worse in peritonitis and hemoperitoneum, this case having been described only one time till now, then the localization mainly sub-serousal and lastly the presence of a component, characterized by an elastotic nature, disposed in islets and interstitial widespread also among the glands, which we have first described in literature.

GnRHa for adhesion formation after uterine serosal injury in an euestrogenic milieu.

OBJECTIVE: To assess whether the adhesion-preventing effect of gonadotropin-releasing hormone agonist (GnRHa) is through hypoestrogenism. STUDY DESIGN: Four groups of previously ovariectomized rats received various combinations of depot leuprolide acetate injection (3.75 mg/kg/mo) subcutaneously, conjugated equine estrogens (50 micrograms/kg/d) orally and phosphate-buffered saline injection subcutaneously, yielding group 1, saline only; group 2, saline and conjugated equine estrogens; group 3, depot leuprolide acetate only; and group 4, depot leuprolide acetate and conjugated equine estrogens. Surgical adhesions were induced by monopolar cautery on the right uterine horn through laparotomy and were then scored on day 21 after surgery. RESULTS: Adhesion scores for rats that received conjugated equine estrogens and saline were significantly higher than scores of those given conjugated equine estrogens and depot leuprolide acetate, depot leuprolide acetate only and saline only (P = .019, .026 and .027, respectively). However, there was no significant difference in the adhesion scores for these three groups. CONCLUSION: Hypoestrogenism results in the development of fewer peritoneal adhesions postoperatively. Our findings also indicated that other mechanisms, in addition to those inducing hypoestrogenism, are at work in the adhesion-preventing effects of GnRHa therapy.

[Postoperative adjuvant immunochemotherapy using Lentinan for advanced gastric carcinoma patients with metastasis in the regional lymph nodes and serosal invasion].

Six patients with gastric cancer, stage IIIA to IV, received intraabdominal cisplatin (CDDP) at laporotomy. This was followed by postoperative intravenous infusion of mitomycin C (MMC), CDDP or fluorouracil (5-FU). When these patients recovered to the extent that permitted oral medication, an immunochemotherapeutic regimen containing either oral UFT (uracil and tegafur) or 5'-deoxy-5-fluorouridine (5'-DFUR), plus intravenous Lentinan (LNT) was administered for a period ranging from one and a half to two years. This postoperative immunochemotherapy was successful in all 6 patients. No relapse has been observed in any of them for at least 4 years. These findings indicate that the chemotherapeutic strategy of administering intraabdominal CDDP immediately after surgery, followed by postoperative immunochemotherapy with pyrimidine-fluoride products plus Lentinan on an outpatient basis may be useful in the treatment of T3 or T4 gastric carcinoma with metastasis in the regional lymph nodes.
