Prospective randomized trial of submucosal hemorrhoidectomy with radiofrequency bistoury vs. conventional Parks' operation.

BACKGROUND: Postoperative pain has always been the main adverse effect of the surgical treatment for hemorrhoids. Surgical techniques evolved mainly to solve this problem as well as postoperative bleeding, stenosis and recurrence. This randomized study compared the results obtained using submucosal hemorrhoidectomy with radiofrequency bistoury with those of the conventional Parks' operation. METHODS: A total of 102 patients were randomized to undergo submucosal hemorrhoidectomy with radiofrequency bistoury (51 patients) or conventional Parks' haemorrhoidectomy (51 patients); loss of some patients at follow-up resulted in 49 and 45 patients available for analysis, respectively. The operating time, amount of pain (VAS scale, 1-10), postoperative analgesic requirement, intra- and postoperative complications, length of hospital stay and patient satisfaction were documented. RESULTS: In comparison to Parks' technique, use of radiofrequency bistoury reduced mean operating time (61.2 min vs. 37.4 min; p<0.05), first postoperative day pain score (5.9 vs. 4.0; p<0.05), pain score at first evacuation (5.7 vs. 4.2; p>0.05), postoperative stay (2.2 days vs. 1.3 days; p<0.05), and pain score on postoperative day 7 (3.6 vs. 2.8; p>0.05). Fecal incontinence was never observed. Incontinence to flatus with spontaneous resolution within 2-3 weeks was reported by 4 subjects in each surgical group. Urinary retention requiring catheterization occurred in 21 subjects in the radiofrequency bistoury group and in 18 patients in the control group. No complications nor recurrences were reported at the 6-month follow-up in either group. CONCLUSIONS: Performing submucosal hemorrhoidectomy with radiofrequency bistoury improves the results obtained with Parks' technique, allowing us to simplify the surgical procedure, reduce operating time, postoperative pain and bleeding, and shorten the hospital stay.

[Milligan-Morgan hemorrhoidectomy with a radiofrequency scalpel].

BACKGROUND: Postoperative pain has always been the main adverse effect of surgical treatment for hemorrhoids. Therefore, surgical techniques evolved mainly to solve this problem and, secondly, postoperative bleeding, recurrences and stenosis. METHODS: Two homogeneous groups of 20 patients each were investigated. Both of them were affected by fourth grade hemorrhoidal prolapse and were homogeneous for age, sex and presentation symptoms. Patients previously treated for other proctologic diseases were excluded. A group was treated with standard Milligan-Morgan hemorrhoidectomy and the other with radiofrequency scissors. Every patient underwent a follow-up protocol based on outpatient visits at 15, 30, 45 postoperative days and 3, 6 and 12 months. RESULTS: The results show a substantial similarity between these techniques. However, radiofrequency scissors further improved the simplicity of the technique and the postoperative adverse effects. In particular, the procedure lasted 7 minutes less with radiofrequency scissors. Patients treated with the radiofrequency technique had their first postoperative evacuation 24 hours before the standard technique and reduced the mean postoperative hospital stay at 2.5 days (4.5 days in the standard group). The incidence of postoperative pain was reduced in patients treated with radiofrequency scalpel and the follow-up controls in both groups didn't show any complication as stenosis or incontinence. CONCLUSIONS: The radiofrequency-performed Milligan-Morgan hemorrhoidectomy is a valuable technique that improves the classical difficulties in execution, reducing the length of hospital stay and the incidence of postoperative pain or other complications.

[Description of a case of giant adrenal myelolipoma and survey of the literature].

Adrenal myelolipoma is a benign tumor affecting the adrenal gland. It is composed by adipose cells and myelopoietic cells present in each normal differentiating stage of the bone marrow. The neoplasia is often asymptomatic, sometimes leading to very large adrenal masses (more than 10 cm in diameter). These are often called "giant myelolipoma". A case is reported and a survey of the literature on this topic is made; the present knowledge of this disease as well as its diagnosis and treatment are discussed also.

[Surgical treatment of hemorrhoid disease. A comparison between techniques].

BACKGROUND: The past years have seen the development of outpatient treatment and surgical procedures for the treatment of hemorrhoid disease in an attempt to reduce postoperative pain on the one hand and execution and hospitalisation times on the other. METHODS: This retrospective study compares the results obtained in the treatment of hemorrhoid disease using three different METHODS. Three groups of 30 patients were selected from those operated during the past 10 years using Milligan-Morgan s technique (Group A), Parks technique (Group B) and radiosurgery (Group C). All patients were matched for sex (50% males and 50% females), age (ranging between 30 and 50 years old), diagnosis (4th degree hemorrhoids not associated with another proctologic pathology such as anal fissures, fistulas, etc.) and referred symptoms. RESULTS: The results obtained allow a positive evaluation to be made of all three surgical techniques, but indicate submucous hemorrhoidectomy using radiosurgery as the method of choice for the treatment of grade III and IV hemorrhoids. CONCLUSIONS: The excellent results achieved using this approach in the authors opinion amply justify the relatively difficult execution and longer operating times.

[Synergism between cyclosporin and gangliosides in anti-rejection therapy. Experimental in vivo model].

In vivo gangliosides (GS) bring about inhibitory effects on the immune response which is attributable to a weakening of the interaction between interleukin-2 (IL-2) and its receptor. In a previous paper we showed that the GS are capable of bringing about in vitro the immunosuppressive power of cyclosporin A CyA2 in this paper we have tried to associate gangliosides (GS) and low dose of CyA in the grafting of rat allogen cutis in order to have in this way in vivo a confirmation of the results previously obtained in vitro. Cutaneous strips taken from Lewis rats were grafted into Sprague Dawley rats and treated for 21 days with intraperitoneal administration of GS, of Cya, and a mixture of the two. The rats were not treated and the rats treated with GS and with CyA separately rejected the graft of the cutis. On the other hand, the use of an association of Gs and CyA brought about a successful graft in 8 rats out of 10. Splenic cells extracted 21 days after the graft from rats treated with GS and with CyA separately were stimulated in vitro with Packweed mitogen (PWM); on the contrary the cells extracted from rats treated with a combination of the two drugs did not react to the stimulation with PWM. Our results show that the GS brings about in vivo the immunosuppressive effects of low doses of CyA.

Reduced nephrotoxicity and hepatoxicity in cyclosporin A therapy by enalapril and spironolactone in rats.

The aim of the study was to define a therapy to be combined with an immunosuppressive drug such as cyclosporin A, in order to partially reduce the nephrotoxic and hepatotoxic effects in the treated rats. Two drugs were considered: enalapril, which is an inhibitor of the angiotensin-converting enzyme, and spironolactone, which is an antagonist of aldosterone. These two drugs interrupt the renin-angiotensinogen-angiotensin chain after this has been activated by cyclosporin A, preventing peripheral vasoconstriction and more specifically the constriction of both glomerular arterioles and hepatic vessels from occurring, thus diminishing the cyclosporin A toxicity in both liver and kidney.

[Cyclosporin (CyA) and H2 antagonists].

An experimental study on rats in order to discovery any possible interaction between Ciclosporin (CyA) and H2-receptor antagonists has been carried out. The results obtained demonstrated that the serum levels of CyA were higher in rats treated with CyA and Cimetidine or Ranitidine, but not Famotidine. It is probable that the increase of ciclosporinaemia is the consequence of an increased hepatotoxicity due to administration of Cya in association with Cimetidine or Ranitidine.

Drug interaction between cyclosporin A and nizatidine in Sprague-Dawley rats.

The H2-receptor antagonists seem to be effective in prevention and treatment of stress ulcer in transplant recipients. In a previous study on rats, an increase was observed in cyclosporinaemia and hepatotoxicity after administration of cimetidine or ranitidine in association with cyclosporin A (CyA). On the contrary, famotidine does not influence the blood CyA levels. The aim of the study was to detect the possible synergistic nephro- and hepatotoxicity of nizatidine administered in association with CyA, assaying the serum creatinine, the ALT and AST levels, and histological features of thirty young male Sprague-Dawley rats, divided into 6 groups of five animals each. After 10 days, all the rats were sacrificed, their blood was collected to assay serum creatinine, ALT, AST and serum CyA levels: kidneys and livers were processed for light microscopy. The results obtained demonstrated that, while the level of creatinine was normal in each group, the average level of transaminase and the serum levels of CyA were significantly higher in the animals receiving the association of CyA and nizatidine. Furthermore, this group demonstrated a mild infiltrate of the liver characterized in some cases with eosinophilic polymorphonuclear cells. In light of the results obtained, it is probable that the increase of cyclosporinaemia is the consequence of an enhanced hepatotoxicity due to administration of CyA in association with nizatidine.
