Percutaneous implant of Denver peritoneo-venous shunt for treatment of refractory ascites: a single center retrospective study.

OBJECTIVE: Refractory ascites is defined as a lack of response to high doses of diuretics or the development of diuretic related side effects, which compel the patient to discontinue the diuretic treatment. Current therapeutic strategies include repeated large-volume paracentesis and transjugular intrahepatic portosystemic shunts (TIPS). Peritoneovenous shunt (Denver shunt) should be considered for patients with refractory ascites who are not candidates for paracentesis or TIPS. This study presents our case series in the implant of Denver peritoneovenous shunt. PATIENTS AND METHODS: Sixty-two patients underwent percutaneous placement of Denver shunt between November 2003 and July 2014. There were 36 men and 26 women. Ascites was secondary to alcoholic cirrhosis in six patients, cryptogenic cirrhosis in six, and virus-related cirrhosis in fifty of them. Liver cirrhosis was classified as Child B in 22 patients and Child C in 40 (no patient was Child A). RESULTS: All implants were successfully performed. There were no intraoperative problems or lethal complications; our patients were hospitalized for 2 or 3 days. Postoperative complications included: infection of the shunt in 3 patients (4.8%), shunt obstruction in 4 (6.4%) and transient abdominal pain in 4 (6.4%). Significant symptomatic relief was obtained in all patients. CONCLUSIONS: The percutaneous placement of a Denver shunt is a technically feasible and effective method for symptomatic relief of refractory ascites.

Late micronutrient deficiency and neurological dysfunction after laparoscopic sleeve gastrectomy: a case report.

Although the micronutrient deficiencies and the related neurological manifestations are widely reported after malabsorbitive weight loss surgery, little is known about cerebral dysfunction secondary to micronutrient impairment in subjects undergoing restrictive interventions (that is, sleeve gastrectomy). We describe a case of a 27-year-old woman with a late development of a Wernicke's encephalopathy (WE) and of severe polyneuropathy following a sleeve gastrectomy without any sleeve stenosis. The impact of WE after bariatric surgery is significantly underestimated. Such a risk should be taken into consideration also after restrictive weight loss surgery. Thus, surgeon/clinicians involved in bariatric patients management must be aware of neurological sequelae related to this intervention.

[Hernia repair and local anesthesia. Results of a controlled randomized clinical trial]. / Ernioplastica inguinale e anestesia locale. Risultati di uno studio randomizzato e controllato.

In the past, general and spinal anesthesia were used for hernia surgery, but nowadays local anesthesia has become the method of choice for hernia repair, especially in outpatient patients. The one-day surgery is sufficient in the management of this pathology. The advantages of local anesthesia are simplicity, safety, extended postoperative analgesia, early mobilization, lack post-anesthesia effects, and low costs. From January 2004 to December 2008 we observed 297 male patients with inguinal hernia. These patients were divided, with rigorous chronological order of hospital admission, in two study groups, different for anesthetic techniques used. Our controlled randomized clinical trial examines the effectiveness of local anesthesia to reduce the time of hospitalization, without alteration of results, and particularly the degree of satisfaction of patients surgical treated for inguinal hernia.
