An analysis of totally implantable central venous port system infections in an urban tertiary referral center.

A frequent complication of central venous port systems (CVP) is infection (CVP-I), either local (CVP-LI) or a life-threatening blood stream infection (CVP-BSI). We examined the course of CVP-I including results of an antibiotic eradication attempt of CVP-BSI. We investigated adults with CVP-I from 2010 to 2018 who had to undergo port explantation or were treated by a combination of systemic antibiotics and antibiotic lock therapy (ALT). In nine years we diagnosed 206 CVP-I (CVP-LI: 52; CVP-BSI: 152). In 146 patients with CVP-I the port system was primary explanted, while 56 patients received antibiotics/ALT. 79% of Gram negative pathogens and 50% of coagulase negative staphylococci (CoNS) were eradicated. Failure of antibiotic treatment was more often associated with short time span since CVP implantation, neutropenia and polymicrobial infection. All patients with non-neoplastic disease survived, while 18/173 patients (10%) with underlying malignant disease had a fatal outcome in the same hospital stay.

Successful treatment of paraneoplastic hypercalcemia in a patient with giant condyloma acuminatum: a case report.

INTRODUCTION: While paraneoplastic syndromes in patients with malignant and metastasizing tumors are common, they are rarely associated with skin tumors showing predominantly local growth patterns. This case report relates to a patient with giant condyloma acuminatum, also called Buschke-Löwenstein tumor, with paraneoplastic hypercalcemia, who was successfully treated with conservative treatment. CASE PRESENTATION: The patient in question is a 48-year-old German man with a giant periscrotal tumor. Before and during the therapy, two episodes of symptomatic hypercalcemia occurred, which were successfully treated by bisphosphonates, intravenous fluids and diuretics. No evidence of lytic bone affection was found. CONCLUSIONS: Paraneoplastic hypercalcemia may occur in patients who have a Buschke-Löwenstein tumor. For patients, where surgery is not an option, established medical therapies like bisphosphonates may be useful in addition to diuretics and infusions.

Experience with a new prosthetic anal sphincter in three coloproctological centres.

BACKGROUND: Fecal incontinence is a common and severely disabling disorder. For patients with severe fecal incontinence, surgery may prove to be the only adequate treatment option. METHODS: This study reports on 43 patients that were treated with a prosthetic sphincter system between 2005 and 2009 in three coloproctological centres. MAIN OUTCOME MEASURES: complications, anal pressures before and after surgery, fecal continence score. RESULTS: The new artificial sphincter system significantly improves continence but leads to some complications in clinical practice. After implantation of the device, continence improved significantly (Keller & Jostarndt continence score 2.6 to 14.3 (P < 0.01)). With the band activated, resting pressure improved significantly as compared to baseline (10.7 mmHg vs. 66.1 mm Hg, P < 0.01). The same holds for anal sphincter squeeze pressure (32.2 mmHg versus 85.9 mm Hg, P < 0.01). Complications occurred in 21 patients (48.8%): 10 surgical and 13 technical. Two patients were affected by both technical and surgical problems. The median time of the occurrence was 3 months postop. In five patients difficulties arose within the first postoperative month leading to explantation of the device in three patients. 90% of complications occurred in the first year. CONCLUSIONS: The soft anal band of AMI (AAS), a new artificial anal sphincter, improves severe anal incontinence, but it must be regarded as a last treatment option to avoid a stoma.

Endoscopic removal of large colorectal polyps: prevention of unnecessary surgery?

PURPOSE: Because of the potential risk of malignancy and technical difficulties in achieving complete removal, large colorectal polyps represent a special problem for the endoscopist. The aim of this study was to evaluate the capabilities and risks of endoscopy in complete removal of large colorectal polyps. METHODS: Endoscopic polypectomy of 186 colorectal polyps larger than 3 cm in diameter (range, 3-13 cm) was performed; 141 were sessile and 45 pedunculated. Most of the polyps were located in the rectum (n = 88), sigmoid (n = 63), and cecum (n = 9). The remaining adenomas were situated in other parts of the colon. Sessile polyps were removed using the piecemeal technique. RESULTS: Histology results showed an adenoma in 167 cases, and invasive carcinoma was present in the adenoma in 19 patients. Of the adenomas, 29 were tubulous, 118 tubulovillous, and 20 villous; adenoma with severe dysplasia was found in 49 cases. Complete endoscopic removal was achieved in all sessile and pedunculated polyps. None of the patients with invasive carcinoma who underwent surgical resection (n = 10) had any evidence of tumor in the resected specimen. Bleeding occurred in 4 patients after polypectomy (2 percent). Perforation occurred in 1 patient (0.5 percent), who had an invasive carcinoma of the cecum. There was no procedure-related mortality. During a mean follow-up period of 40 (range, 3-87) months, 6 patients presented with recurrence of a benign adenoma (3 percent), which was treated endoscopically, and 1 patient presented with a recurrent invasive carcinoma, which was treated surgically. CONCLUSIONS: Endoscopic polypectomy is a safe and effective method of treating large colorectal polyps.
