Primary graft failure after heart transplantation: the importance of donor pharmacological management.

BACKGROUND: Primary graft failure (PGF) remains the strongest determinant of perioperative mortality after heart transplantation (HT). Donor management may play an important role in the incidence of PGF. MATERIALS AND METHODS: Multivariate analysis was used to identify PGF determinants after HT. Donor and recipient data were analyzed together with preharvest management information and perioperative results. PGF was defined as the need for mechanical circulatory support immediately post-HT. RESULTS: Isolated HT was performed in 54 consecutive patients from January 2006 to June 2009. PGF occurred in 11 (20%) patients. Upon univariate analysis, preoperative mean pulmonary arterial pressure was significantly higher among patients developing PGF (P=.02). The donors for PGF patients had more often been managed with high inotropic support (dopamine>10 microg/kg/min and/or alpha agonists>0.06 microg/kg/min; P=.008). In contrast, death for head trauma was more common among donors for patients who did not develop PGF (P=.02). In-hospital mortality was 13% (7/54); 71% of these deceased patients displayed PGF (5/7). Upon multivariate analysis, preharvest high donor inotropic support was the strongest determinant of PGF (P=.01, odds ratio [OR]=7.5). Donor death due to head trauma showed a protective effect against PGF (P=.03, OR=0.1). CONCLUSION: PGF remains a lethal perioperative complication despite modern tools for prompt cardiac mechanical assistance. As a result of the organ shortage, many centers accept marginal hearts assuming that donor hemodynamic management shows a reduced impact on PGF. We suggest a timely evaluation of the hazards for PGF whenever high inotropic support is used, especially among donors dying for causes other than head trauma.

[Use of monofilament prosthesis in inguinal hernia treatment: cost-benefit ratio]. / L'impiego delle protesi in monofilamento nella terapia dell'ernia inguinale: rapporto costo-beneficio.

BACKGROUND: The authors aimed to demonstrate the real advantages in terms of cost and patient comfort of inguinal hernia surgery using monofilament prostheses. METHODS: A retrospective survey was carried out on two groups of patients: the first group, consisting of 1032 patients who underwent inguinal hernia surgery under general anesthetic between 1985 and 1995 at the Institute of General Surgery at the University Polyclinic of Messina, included cases of both emergency and elective surgery that did not use monofilament prosthesis. The second group, consisting of 348 patients operated under local anesthesia between 1996 and 1999 at the IV Division of General Surgery at the University Polyclinic of Messina, included cases of both emergency and elective surgery using tension-free techniques and polypropylene mesh. The numbers of recidivations and complications were compared, together with the relative costs of the methods used in both groups. CONCLUSIONS: In the light of these experimental results, it is clear that the use of biocompatible alloplastic materials in monofilament considerably reduces the risks of recidivation, without no significant increase in the number of dehiscences, infections or postoperative complications. Moreover, there was a striking reduction in costs linked not only to the shorter hospitalisation of patients and the reduced use of painkillers, but also a fall in the number of future hospital admissions owing to recidivation.

[Trans-anal resection of low rectal neoplasms]. / Exeresi transanale delle neoplasie del retto basso.

BACKGROUND: The rising incidence of colorectal neoplasms, and in particular those localised in the lower rectum is stressed and the therapeutic opportunities offered by the trans-anal resection technique are underlined. METHODS: The indispensable conditions for adopting a surgical approach are pointed out. These are identified as the size of the neoplasm, which should not exceed 4 cm, the fixity, site, the polypoid and non-ulcerated nature of the lesion, and the involvement of not more than 1/4 of the circumference of the bowel. Using these inclusion criteria, the authors operated on five patients in the 4th Division of General Surgery at G. Martino Polyclinic in Messina, using trans-anal resection of low rectal neoplasm. RESULTS: No hemorrhagic complications or lesions in the visceral wall occurred. All patients underwent a follow-up of up to 36 months and to date no patient has presented long-term metastasis; local recidivation was observed in one patient after 14 months and this was treated using the trans-anal method. CONCLUSIONS: The authors affirm that trans-anal resection may be regarded as the elective treatment of patients with neoplasms confined to the visceral wall and without dissemination; it is palliative in cases where the tumour is larger than 4 cm, with lymph node involvement. But even in this case, and in more advanced situations, this method allows mortality due to occlusive complications to be reduced and ensures a better quality of residual life.

[Anal carcinoma]. / Il carcinoma anale.

The authors, want to demonstrate the operation of abdominal perianal rectum amputation, and it is considered absolute, even 80 years, in the treatment of the anal neoplasia, it is superseded by alternative methods represented by protocols radio-chemo-therapeutic associated or less to the surgery treatment. They make then a retrospective valuation since 1963 till our days on 54 patients. In the 6 patients (stadium I-II) treated after 1982 with protocols of freemall, it is was obtained disappearance of the neoplasia about 50% the cases. On overcoming of the results there was in a second group of 8 patients (1987) treated always with protocol of Greenall, in 5 of these (62.5%) could observe absence of remaining of disease. In the third group (1993) on 8 patients treated with therapy fixed radio-chemo, it was registered the absence of the residual of illness in 6 patients(75.5%). Finally, from the analysis of patients observed in the last seven years, 5 of which suffered by Ca squamous in different evolutive stadium (one I stadium, three II stadium and one stadium III-B), the stadium I and II were treated with the protocol radio-chemotherapeutic obtaining total remission of the disease in the 100% of the cases. In the follow-up of 45 patients, 12 of whose were treated with the therapy combined radio-chemo and of these 10 were valuable for survival to 5 years which was about 70% superior to patients treated with only surgery therapy.

[Carcinoma of the gastric stump]. / Il carcinoma del monocone gastrico.

After having emphasized that carcinoma of the gastric stump represents a "major" risk in patients undergoing gastric resection, the authors describe the physiopathology of the new anatomical and functional status of the gastroenteric apparatus and underline the probable etiopathogenetic stages attributable to carcinogenesis. They then describe the treatment of this neoplasia with a marked aggressive character and conclude with the affirmation that the surgeon's efforts must be focused on the correct execution of gastroresection and the follow-up of gastro-resected patients in order to allow the early identification of precancerous conditions and therefore the commencement rational oncological prophylaxis.
