Laparoskopische Therapie von Leber-, Milzund Mesenterialzysten

2008

Five women and one man (average age 62.5 [20-64] years) with symptomatic intraabdominal cysts at different sites (liver: n = 3; spleen: n = 2; mesentery: n = 1) had them removed by laparoscopic surgery. Broad fenestration was performed with the hepatic and splenic cysts, while the mesenteric cyst was enucleated from the mesentery. There were no intra- or postoperative complications. Median duration of operation was 60 (45-125) min, postoperative hospital stay was 5 (3-6) days. After a median follow-up period of 8 (1-12) months a 3 cm residual cyst was found in the patient with the splenic cyst, but all patients were free of symptoms. -Laparoscopic surgery is a low-stress alternative to conv…

Removal of carbon and nutrients from wastewater in a moving bed membrane biofilm reactor: the influence of the sludge retention time

2016

A University of Cape Town (UCT) pilot plant combining both membrane bioreactor (MBR) and moving bed biofilm reactor (MBBR) technology was monitored. Three experimental Phases were carried out by varying the mixed liquor sludge retention time (SRT) (indefinite, 30 and 15 days, respectively). The system performance has been investigated during experiments in terms of: organic carbon, nitrogen and phosphorus removal, biokinetic/stoichiometric constants, membrane fouling tendency and sludge dewaterability. The observed results showed that by decreasing the SRT the UCT pilot plant was able to maintain very high total COD removal efficiencies, whilst the biological COD removal efficiency showed a…

Complications in Craniovertebral Junction Instrumentation: Hardware Removal Can Be Associated with Long-Lasting Stability. Personal Experience

2017

Background The causes of craniovertebral junction (CVJ) instabilities include trauma, rheumatological diseases, tumors, infections, congenital malformations, and degenerative disease processes; these complex pathologies often require CVJ instrumentation. Hardware complications were analyzed in a personal series of 48 treated patients. In light of the analysis of very unusual radiological and clinical findings, the authors tried to better investigate the related mechanisms and to reach possible useful conclusions. Methods In a series of 48 patients who underwent CVJ instrumentation and fusion procedures in our Institution, we describe three cases of hardware failure, due to: (1) infection; (…

Deep seroma after incisional hernia repair. Case reports and review of the literature.

2015

Wound-related complications are common after incisional hernia repair with mesh; seroma formation is the most frequent problem. The formation of a deep seroma has been rarely reported in the literature.In one year, September 2012-2013, 136 patients underwent surgery for incisional hernia repair, both elective and urgent.The following complications were observed: one dislocation of polypropylene prosthesis, a massive relapsed seroma and two deep seromas described in this article. A 63- years-old female underwent open incisional hernia repair with an intraperitoneal PTFE patch. She developed recurrent seroma under the mesh drained percutaneously, and finally the prosthesis was removed. A 72- …

Extraction of Entrapped Capsules from the Small Bowel by Means of Push-and-Pull Enteroscopy with the Double-Balloon Technique

2005

The new technique of push-and-pull enteroscopy using the double-balloon technique (double-balloon enteroscopy) makes it possible to remove swallowed foreign bodies causing intestinal obstruction deep in the small bowel without the need for surgical laparotomy. This report describes two cases of enteroscopic removal of entrapped capsules. In one patient with acute recurrent intestinal bleeding and recurrent abdominal pain, Crohn's disease had been suspected on capsule endoscopy. The second patient, with known Crohn's disease, was suffering from abdominal pain and underwent capsule endoscopy for investigation of the small bowel. Prior enteroclysis had not revealed stenoses in either patient. …

Regional anticoagulation with heparin of an extracorporeal CO2 removal circuit: a case report

2019

Abstract Background Extracorporeal carbon dioxide removal is an increasingly used respiratory support technique. As is true of all extracorporeal techniques, extracorporeal carbon dioxide removal needs proper anticoagulation. We report a case of a patient at risk of bleeding complications who was treated with extracorporeal carbon dioxide removal and anticoagulated with a regional technique. Case presentation A 56-year-old Caucasian man with a history of chronic obstructive pulmonary disease exacerbation required extracorporeal carbon dioxide removal for severe hypercapnia and acidosis despite mechanical ventilation. The extracorporeal circuit was anticoagulated using a regional heparin tec…

Local Shock-Wave Lithotripsy of Distal Ureteral Calculi

1988

Abstract Since the initiation of the clinical trial utilizing a second-generation lithotripor (Lithostar, Siemens, Erlangen, FRG), 96 patients with distal ureteral calculi (i.e. calculi below the pelvic brim) underwent local shock-wave lithotripsy. Routine treatment was conducted under intravenous sedation and light analgesia only. Complete stone disintegration was achieved in 84 patients (87.5%), 11 requiring two sessions and 1 patient, three. In 7 patients ureteroscopy became necessary after unsuccessful local shock-wave treatment. In 2 of these patients a 9-french flexible ureteroscope and the Storz Q-switched neodymium-YAG laser was used for stone disintegration. In 3 cases loop extract…

Regeneration of the testes in the clawed toad (Discoglossus pictus Otth.) after complete surgical removal

1967

Dopo ablazione totale dei testicoli inDiscoglossus pictus si ha rigenerazione. Nei testicoli rigenerati si riscontrano spermatociti in tutti gli stadi di sviluppo e talvolta anche spermi. E avanzata l'ipotesi che la rigenerazione avvenga a partire da cellule somatiche degli spermidutti.
