RESUMO

We present a case of long-term survival of a patient who underwent living-donor liver transplantation for unresectable liver metastases of colon cancer. Two years after left hemicolectomy and subsequent to repeated liver resections, this patient presented with unresectable metastatic disease confined to the liver. She was offered a living-donor liver transplantation, and her husband agreed to be the donor. Five years after transplant, she was alive and recurrence free.

RESUMO

Solid pseudo-papillary tumors (SPT) are rare primary tumors of the pancreas that primarily affect young women. They are of borderline malignancy, and, unlike other pancreatic malignancies, the prognosis after resection is quite good. However, metastatic disease does occur; the liver is the most common site of tumor dissemination. Herein we have reported a case of a 20-year-old woman who presented with multiple, bilateral liver metastases at 3 years after distal pancreatectomy for SPT of the body and tail of the pancreas. The patient underwent living donor liver transplantation (LDLT) and is alive and disease-free at 24 months after surgery. In this report, we discuss the treatment of liver metastases from SPT, with an emphasis on the possible role of orthotopic liver transplantation (OLT).

RESUMO

We report a case of acute liver ischemia resulting in liver failure that occurred due to celiac trunk occlusion by an aortic dissection. A 53-year-old patient presented with clinical signs of acute abdomen. He underwent an urgent laparotomy, which revealed a splenic infarction and thrombosis of the celiac artery all the way to the porta hepatis. Imaging showed that an acute thoracoabdominal aortic dissection was present, resulting in compression of the celiac trunk. The aorta was repaired with an intervascular graft; however, an acute insufficiency of the liver ensued, and the patient was urgently transplanted. To the best of our knowledge, this is the first report of vascular compromise of the liver due to acute aortic dissection that would require liver transplantation.

RESUMO

In studies intended to improve healing of transected Achilles tendon, effective was a stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, M.W. 1419). Currently in clinical trials for inflammatory bowel disease (PLD-116, PL 14736, Pliva), it ameliorates internal and external wound healing. In rats, the right Achilles tendon transected (5 mm proximal to its calcaneal insertion) presents with a large tendon defect between cut ends. Agents (/kg b.w., i.p., once time daily) (BPC 157 (dissolved in saline, with no carrier addition) (10 microg, 10 ng or 10 pg) or saline (5.0 ml)), were firstly applied at 30 min after surgery, the last application at 24 h before autopsy. Achilles functional index (AFI) was assessed once time daily. Biomechanical, microscopical and macroscopical assessment was on day 1, 4, 7, 10 and 14. Controls generally have severely compromised healing. In comparison, pentadecapeptide BPC 157 fully improves recovery: (i) biomechanically, increased load of failure, load of failure per area and Young's modulus of elasticity; (ii) functionally, significantly higher AFI-values; (iii) microscopically, more mononuclears and less granulocytes, superior formation of fibroblasts, reticulin and collagen; (iv) macroscopically, smaller size and depth of tendon defect, and subsequently the reestablishment of full tendon integrity. Likewise, unlike TGF-beta, pentadecapeptide BPC 157, presenting with no effect on the growth of cultured cell of its own, consistently opposed 4-hydroxynonenal (HNE), a negative modulator of the growth. HNE-effect is opposed in both combinations: BPC 157+HNE (HNE growth inhibiting effect reversed into growth stimulation of cultured tendocytes) and HNE+BPC 157(abolished inhibiting activity of the aldehyde), both in the presence of serum and serum deprived conditions. In conclusion, these findings, particularly, Achilles tendon transection fully recovered in rats, peptide stability suitable delivery, usefully favor gastric pentadecapeptide BPC 157 in future Achilles tendon therapy.

RESUMO

BACKGROUND/AIMS: To investigate the potential value of the use of the fibrin glue-antibiotic mixture in the treatment of anal fistulae. MATERIALS AND METHODS: This study included 69 patients with idiopathic nonspecific anal fistulae. Patients with IBD (inflammatory bowel disease), TBC, actinomycosis, and cancer were excluded from the study. The microbiological analysis of the discharge of the fistula was done routinely. If there was any doubt about vertical classification of the fistulous tract MR of anal canal was necessary. As regards the vertical disposition, 39 fistulae were classified as intersphincteric and 30 as transsphincteric, and as to the length of the fistulous tract, 24 fistulas had tracts 3.5 cm long. All fistulae were first treated with the lavage of the fistulous tract with antibiotic solution until a sterile microbiological finding was obtained. This was followed by electrocoagulation of the fistulous tract with a special probe for the eradication of granulomatous tissue. Finally the fibrin glue-antibiotic mixture (Tisseel, Immuno Ltd., Vienna, Austria) was applied. RESULTS: After a follow-up of 18-36 months (median 28) 18 patients (26%) had a recurrence; among these, intersphincteric fistula recurred in 9 patients (23%) and transsphincteric also in 9 (30%). Regarding the length of the fistulous tract, a fistula with a 3.5 cm long tract in 5 (11%). CONCLUSION: The analysis showed that the success of the treatment of anal fistulae with fibrin glue-antibiotic mixture was independent of the vertical disposition of the fistula, and was dependent on the length of the fistulous tract. Surgical treatment remains a golden standard for simple fistulae with a tract

RESUMO

An 18 year-old resident of Zagreb was admitted to our hospital with intermittent pain in the right subcostal region. On examination, a palpable resistance was found in the upper abdomen. After extensive clinical and laboratory tests, a tumor of the pancreatic head, 80-85 mm in diameter, was verified. Cytologically, a diagnosis of microcystic adenoma of the pancreas was established. The patient underwent a cephalic pancreatoduodenectomy with preservation of the pylorus. Six months later the patient was no longer on a diet and, at follow-up, 3 years after surgery, she is symptom-free and feeling well.

RESUMO

Gastrectomy often results in increased likelihood of osteoporosis, metabolic aberration, and risk of fracture, and there is a need for a gastric peptide with osteogenic activity. A novel stomach pentadecapeptide, BPC-157, improves wound and fracture healing in rats in addition to having an angiogenic effect. Therefore, in the present study, using a segmental osteoperiosteal bone defect (0.8 cm, in the middle of the left radius) that remained incompletely healed in all control rabbits for 6 weeks (assessed in 2 week intervals), pentadecapeptide BPC-157 was further studied (either percutaneously given locally [10 microg/kg body weight] into the bone defect, or applied intramuscularly [intermittently, at postoperative days 7, 9, 14, and 16 at 10 microg/kg body weight] or continuously [once per day, postoperative days 7-21 at 10 microg or 10 ng/kg body weight]). For comparison, rabbits percutaneously received locally autologous bone marrow (2 mL, postoperative day 7). As standard treatment, immediately after its formation, the bone defect was filled with an autologous cortical graft. Saline-treated (2 mL intramuscularly [i.m.] and 2 mL locally into the bone defect), injured animals were used as controls. Pentadecapeptide BPC-157 significantly improved the healing of segmental bone defects. For instance, upon radiographic assessment, the callus surface, microphotodensitometry, quantitative histomorphometry (10 microg/kg body weight i.m. for 14 days), or quantitative histomorphometry (10 ng/kg body weight i.m. for 14 days) the effect of pentadecapeptide BPC-157 was shown to correspond to improvement after local application of bone marrow or autologous cortical graft. Moreover, a comparison of the number of animals with unhealed defects (all controls) or healed defects (complete bony continuity across the defect site) showed that besides pentadecapeptide intramuscular application for 14 days (i.e., local application of bone marrow or autologous cortical graft), also following other pentadecapeptide BPC-157 regimens (local application, or intermittent intramuscular administration), the number of animals with healed defect was increased. Hopefully, in the light of the suggested stomach significance for bone homeostasis, the possible relevance of this pentadecapeptide BPC-157 effect (local or intramuscular effectiveness, lack of unwanted effects) could be a basis for methods of choice in the future management of healing impairment in humans, and requires further investigation.

RESUMO

Adaptive cytoprotection in the stomach was originally defined by applying the exogenous irritants only. The contribution of endogenous irritants as inductors of initial lesions was not specially evaluated. No attempt was made to either focus antiulcer agent activity on adaptive cytoprotection, or split their 'cytoprotection' into complex adaptive cytoprotective activity and simple cytoprotective effects. Agents had so far not been applied simultaneously with the second challenge with ethanol (or irritant), when differences between cytoprotection and adaptive cytoprotection appear. Gastrojejunal anastomosis for 24 h in rats was introduced as new model for analyzing cytoprotection/adaptive cytoprotection. The contribution of the up-normal level of endogenous irritants and the endogenous small irritant-induced minor lesions during the adaptive cytoprotection were studied. The effect of late challenge with 96% ethanol in the presence of an up-normal level of endogenous irritants and endogenous small irritant-induced minor lesions was compared with results of classic studies of ethanol-induced gastric lesions in normal rats (1 ml/rat i.g.). Antiulcer agents or a prostaglandins-synthesis inhibitor, indomethacin, given once only in classic studies, were given at several points during injury induction: (i) surgery, (ii) mild ethanol, (iii) strong ethanol, (iv) strong ethanol applied after a suitable period following either mild ethanol or surgery). Their effects were compared in rats treated as follows: exogenous irritant studies (96% or 20% ethanol), exogenous/exogenous irritant studies (20% ethanol 1 h before 96% ethanol), endogenous irritant studies (gastrojejunal anastomosis for 24 h), and endogenous/exogenous irritant studies (gastrojejunal anastomosis for 24 h before 96% ethanol). Characteristic of the various irritants differed: the (preceding) small irritants (exogenous (i.e., mild ethanol in healthy intact rats) (exogenous irritant studies) vs. endogenous (e.g., (increased) gastric acid secretion, duodenal reflux in gastric content in rats with termino-lateral gastrojejunal anastomosis) (endogenous irritant studies)). These factors caused modifications of agents' activities not, as initially thought, giving simple 'cytoprotection', but being only cytoprotective, or adaptive cytoprotective, or both cytoprotective and adaptive cytoprotective. Atropine (10 mg/kg i.p.) and ranitidine (10 mg) had only cytoprotective activity (exogenous irritant-studies), whereas pentadecapeptide BPC157 (10 microg or 10 ng), and omeprazole (10 mg) had mainly adaptive cytoprotective activity (endogenous/exogenous irritant studies) or both cytoprotective and adaptive cytoprotective activities (exogenous/exogenous irritant studies). Augmentation of the lesions by indomethacin (5 mg/kg s.c.), showed that only events preceding the late challenge with ethanol may be prostaglandin-dependent in both models. The second, adaptive cytoprotective part, seen after late ethanol challenge, may be either prostaglandin-dependent (exogenous/exogenous irritant studies) or non-dependent (endogenous/exogenous irritant studies). Both spontaneous lesion reduction, as an essential mechanism of adaptive cytoprotection, and the further lesion reduction by agents, such as pentadecapeptide BPC 157 and omeprazole, suggests that these agents function as an essential link between the various reactions in cytoprotection/adaptive cytoprotection.

RESUMO

Recently, the effectiveness of pentadecapeptide BPC 157 and other anti-ulcer agents, called 'direct cytoprotection', was evidenced in totally gastrectomized rats duodenum challenged with cysteamine 24 h after surgery, and sacrificed 24 h after ulcerogen application. The further focus was on the possibility that this effect could be seen over a more prolonged period (1, 2, 4 weeks), and in other parts of the gastrointestinal tract (i.e. oesophagus). After the removal of the stomach, the oesophagus and jejunum were joined by a termino-lateral anastomosis. The animals were euthanized 7, 14 or 28 d after surgery, when oesophagitis was blindly assessed both macroscopically (percentage of ulcerations areas) and microscopically (percentage of areas of ulcers, regeneration and hyperplasia; number of inflammatory cells - polymorphonuclear and mononuclear). Starting 24 h after surgery, the medication was continuously given in the drinking water, in a volume of 12.5 mL/rat daily, until euthanasia at the end of the observation period, i.e. 7, 14, 28 d following surgery. Based on previous experiments, the doses of agents were daily calculated per kg b.w. as follows: BPC 157 125 mg or 125 ng, cholestyramine 2.5 mg, ranitidine 125 mg, sucralfate 725 mg, whereas controls received 72.5 mL x kg(-1) water. In support of these initial findings, and considering gastrectomized acid-free rats as an ideal model for long-term cytoprotective studies as well, pentadecapeptide BPC 157 markedly attenuated termino-lateral oesophagojejunal anastomosis-reflux oesophagitis also over a quite prolonged period. This efficacy was only partly shared by other anti-ulcer agents. After 1-week-old oesophagitis (microscopical assessment), but not after 2 or 4 weeks, less damaged mucosa was noted in rats drinking ranitidine or sucralfate compared to controls. Similar effectiveness was noted for cholestyramine. The obtained results were supported also by inflammatory cell assessment. Compared with control values, BPC 157-treated groups consistently presented less polymorphonuclears and less mononuclears in all assessed periods. Interestingly, the values obtained in other treated groups showed no difference compared with control values. Thus, despite limitations, a generalization supporting a direct importance of a common cytoprotective approach, could be clearly provided. A useful, long-lasting cytoprotective activity (apparently more prominent in BPC 157 rats, than in reference agents, ranitidine, sucralfate, as well as cholestyramine) may be a likely suitable therapy in otherwise resistant reflux oesophagitis conditions.

RESUMO

A superior effectiveness in various lesion assays was noted for the novel pentadecapeptide BPC 157, originated from human gastric juice protein (BPC) and claimed to be a cytoprotective agent. From this viewpoint, as a previously untreated experimental improvement to create an acid-free environmental for cytoprotection studies, total gastrectomy was done 24 hr before the ulcerogenic procedure. In the absence of stomach and gastric acid, the damaging effects of cysteamine (400 mg/kg subcutaneously, death 24 hr thereafter), to date thought to be an acid-related duodenal ulcerogen, and the BPC 157 cytoprotective effect (10 microg or 10 ng/kg intraperitoneally) were further challenged. BPC 157 was compared with reference agents [cimetidine (50), ranitidine (10), omeprazole (10), bromocriptine (10) and atropine (10) (mg/kg intraperitoneally, 1 hr before cysteamine] known to be also cytoprotective. In naive rats, with intact stomach, all of them showed a strong beneficial effect. Interestingly, in gastrectomized animals, the application of BPC 157 or the reference agents before cysteamine significantly prevented the otherwise severe duodenal lesion development noted in the control gastrectomized cysteamine rats. In groups without cysteamine, no lesions were noted (laparotomy, gastrectomy only, 24 or 48 hr postsurgical period), nor was lesion potentiation seen in cysteamine-treated laparotomized animals. In summary, these findings--equal damaging effect of cysteamine and equal protection of pentadecapeptide BPC 157 and reference agents in gastrectomized and rats with intact stomach--seem to be particularly relevant for a cytoprotective viewpoint. Without a stomach, the cysteamine damaging effect was convincingly defined as an essential gastric acid-independent injury (analogous to ethanol gastric lesions). Likewise, a high "cytoprotective capacity," apparently acid independent, common for all tested agents (novel pentadecapeptide BPC 157, cimetidine, ranitidine, omeprazole and atropine) could be clearly stressed.
