Diathermy haemorrhoidectomy: reasons for a therapeutic choice.

BACKGROUND: Diathermy haemorrhoidectomy is an effective technique for the management of 2nd, 3rd and 4th degree haemorrhoids. The anal cushions are excised by use of diathermy without ligature of the vascular pedicles. The aim of the present study is to evaluate the efficacy and tolerability of this technique. METHODS: Between September 1999 and September 2003, 84 patients with 2nd, 3rd, and 4th degree haemorrhoids underwent diathermy haemorrhoidectomy. Patients were discharged the same day or the day after. All the patients were asked to complete two questionnaires one on the level of pain they experienced and the other on their expectation of pain. Patients were followed-up for 1 to 4 years (range 12-48 months, mean 20.5). RESULTS: The average pain severity score on a visual analogue scale (0-10) was 3.06 +/- 0.38 and consistently lower than expected. The majority of patients returned to their usual daily activities within 4 days and all of them returned to work within 11 days. A mild residual secretion persisted for 4 to 5 weeks. None of our patients experienced postoperative haemorrhage, complete stenosis or sphincteric disturbances. CONCLUSIONS: Diathermy haemorrhoidectomy appears to be a safe, low cost and effective technique for the treatment of haemorrhoids. It is well tolerated by patients.

Plasma levels of t-PA and PAI-1 correlate with the formation of experimental post-surgical peritoneal adhesions.

This study has evaluated whether systemic changes of plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) parallel the adhesions development and whether they could be used as predictors of adhesion risk. This has been studied in an animal model of post-surgical peritoneal adhesion by monitoring for 10 days the plasma and tissue levels of t-PA and PAI-1. The results showed that both tissular and plasmatic levels of t-PA were decreased in concomitance with the development of peritoneal adhesions. In contrast, PAI-1 was found increased into the tissue and into the plasma samples of the rats taken at 5 and 10 days time points. Inflammatory mediators such as ICAM-1, VCAM-1, and IL-6 within the peritoneal lavage fluid also correlated with the adhesion formation process. In conclusion, post-surgical peritoneal adhesions provide alterations of local inflammatory components and local and systemic fibrinolytic components, possibly with PAI-1 quenching t-PA. This may have potential for the identification of high-risk patients.

[The Keel Mesh prosthesis: an innovative surgical device for a modern Bassini inguino-crural hernia operation without limits]. / Keel mesh: un inmlovativo "device" chirurgico per una Bassini moderna e senza limiti.

Accepting the therapeutic rational underlying laparoscopic and suprapubic laparotomy access, the same therapeutic goal is achieved through direct inguinal access. In this way, using just one prosthesis, inguinal-crural hernias of the Fruchaud pectineus orifice can be treated. The patented three-dimensional pre-cut Keel Mesh prosthesis made of polypropylene monofilament interwoven in a mesh, is tension-free and endowed with plastic memory. It is applied using a slightly modified Lichtenstein technique and is composed of two assembled elements (A and B-C) of different shapes and sizes. From May 2000 to December 2005, the Keel Mesh prosthesis was used in 358 surgical inguino-crural alloplasty operations according to Lichtenstein-De Pascale in 328 patients. Thirty patients were treated with bilateral allo-plasties. Coexistence of a crural hernia was found in 13 male and 4 female patients (5%). At the present time all the patients who are entering into follow-up at different times show perfect compliance of the prosthesis with no relapses. The theoretical and practical considerations regarding the production of the Keel Mesh prosthesis and its easy application suggest it is an extremely valid, rational device for the initial and combined treatment of inguinal and crural hernia.

Iatrogenic splenic injuries.

Inadvertent intraoperative injuries to the spleen by the surgical team represent an underestimated complication of many abdominal procedures. Surgical reports often lack the necessary details and frequently a clear justification as why a splenectomy was indicated is not provided. The wide variability of the incidence reported in literature makes it is difficult to evaluate the morbidity and mortality associated to these injuries and to assess the early and late consequences of this complication, although it is still possible to infer some of the reasons for these inconsistencies and to roughly estimate both clinical and socio-economical effects of this injury. Given the degree of uncertainty on the incidence of iatrogenic and traumatic splenic injuries and on the immediate and long-term sequelae suffered by asplenic patients, we thought that a multicentric prospective study was warranted. We are therefore announcing the start of a study involving several Institutions within the Regione Campania, aimed at obtaining an unbiased estimate of the incidence of these injuries, together with the extent and severity of their long-term complications. We also aim to help promoting a more effective prevention.

Role of blood AFP mRNA and tumor grade in the preoperative prognostic evaluation of patients with hepatocellular carcinoma.

AIM: To explore the potential prognostic role of preoperative tumor grade and blood AFP mRNA in a cohort of patients with hepatocellular carcinoma (HCC) eligible for radical therapies according to a well-defined treatment algorithm not including nodule size and number as absolute selection criteria. METHODS: Fifty patients with a diagnosis of HCC were prospectively enrolled in the study. Inclusion criteria were: (1) histological assessment of tumor grade by means of percutaneous biopsies; (2) determination of AFP mRNA status in the blood; (3) patient's eligibility for radical therapies. RESULTS: At preoperative evaluation, 54% of the study group had a well-differentiated HCC, 42% had AFP mRNA in the blood, 40% had a tumor larger than 5 cm and 56% had more than one nodule. Surgery (resection or liver transplantation) was performed in 29 patients, while 21 had percutaneous ablation procedures. After a median follow-up of 28 mo, 12-, 24-, and 36-mo survival rates were 78%, 58%, and 51%, respectively. Surgical therapy, performance status and three tumor-related variables (AFP mRNA, HCC grade and gross vascular invasion) resulted as significant survival predictors at univariate analysis. Nodule size and number did not perform as significant prognosticators. Multivariate study selected only surgical therapy and a biologically early HCC profile (AFP mRNA negative and well-differentiated tumor without gross vascular invasion) as independent survival variables. CONCLUSION: The preoperative determination of tumor grade and blood AFP mRNA status may potentially refine the prognostic evaluation of HCC patients and improve the selection process for radical therapies.
