RESUMO
BACKGROUND AND AIM OF THE STUDY: Driveline infections in patients with implantable left ventricular assist devices (VAD) carry increasing risk for pump infection, thromboembolic events, decreased quality of life, and increased hospitalization. We report our experience with a surgical technique for refractory driveline infections without mediastinitis consisting of translocation and wrapping of the driveline with greater omentum tissue. METHODS: We retrospectively reviewed data of VAD patients who underwent surgical treatment by translocation and wrapping with omentum for severe chronic driveline infection. RESULTS: Thirteen patients were treated between January 2010 and October 2015; 12 (92%) were male, and the mean age was 56 ± 14 years. Ten patients (77%) were managed with driveline sheathing with omentum and repositioning with a new exit site, and three (23%), suffering from driveline fistula, with driveline covering with omentum maintaining the previous exit site. Three episodes of postoperative bleeding (23%) required surgical revision. Twelve patients (92%) were discharged from the hospital and one (8%) died. Nine patients (69%) were free from infection at the time of discharge, and three (23%) had recurrence of infection within the first postoperative year. Only four patients (31%) required admission to the intensive care unit; overall median hospital stay was 23 days (range 7-205 days). CONCLUSIONS: Driveline relocation with use of omentum is a feasible and effective procedure in selected cases of chronic severe driveline infection. The risk for perioperative bleeding should be taken into consideration and carefully monitored.

OBJECTIVES: This was a prospective, randomised, placebo-controlled, double-blind multicentre trial to analyse the efficacy of choline citrate in patients with postoperative ileus (POI) after elective colorectal surgery. METHODS: From October 2005 until June 2008, 122 patients with POI were randomised to receive choline citrate or placebo. One hundred twenty patients were evaluable for tolerability and 107 patients were evaluable for efficacy. The treatment group, 47% (50/107), received 300.2 mg choline citrate intravenously, while the placebo group, 53% (57/107), received sodium chloride. Injections were performed every 12 h until defecation. RESULTS: Demographic data analysis did not show clinically differences between both groups. Operative procedures included 40% (43/107) hemicolectomy, 38% (41/107) sigmoid resection and 22% (23/107) other colorectal resections. Defecation occurred after an average of 91.8 ± 26.6 h postoperatively in the treatment group, vs. 96.7 ± 35.2 h in the placebo group (p = 0.805). After laparoscopy, defecation occurred after 78.7 ± 25.3 h, vs. 99.2 ± 31.6 h after laparotomy (p = 0.001). Serious adverse effects occurred in 2% (1/60) in the treatment group, vs. 3% (2/60) in the placebo group. None of the events have been assessed as related to the study medication. CONCLUSION: An efficacy of choline citrate in the treatment of POI after elective colorectal surgery could not be verified. The problem of POI requiring drug treatment seems to be less frequent than suggested by the literature. With technical advances in surgery, especially laparoscopic and fast track surgery, the frequency of POI will further decrease in the future.

OBJECTIVE: To analyze patient outcome in the first 14 months of the German natural orifice translumenal endoscopic surgery (NOTES) registry (GNR). SUMMARY BACKGROUND DATA: NOTES is a new surgical concept, which permits scarless intra-abdominal operations through natural orifices, such as the mouth, vagina, rectum, or urethra. The GNR was established as a nationwide outcome database to allow the monitoring and safe introduction of this technique in Germany. METHODS: The GNR was designed as a voluntary database with online access. All surgeons in Germany who performed NOTES procedures were requested to participate in the registry. The GNR recorded demographical and therapy data as well as data on the postoperative course. RESULTS: A total of 572 target organs were operated in 551 patients. Cholecystectomies accounted for 85.3% of all NOTES procedures. All procedures were performed in female patients using transvaginal hybrid technique. Complications occurred in 3.1% of all patients, conversions to laparoscopy or open surgery in 4.9%. In cholecystectomies, institutional case volume, obesity, and age had substantial effect on conversion rate, operation length, and length of hospital stay, but no effect on complications. CONCLUSIONS: Despite the fact that NOTES has just recently been introduced, the technique has already gained considerable clinical application. Transvaginal hybrid NOTES cholecystectomy is a practicable and safe alternative to laparoscopic resection even in obese or older patients.

Mediastinitis is more frequent in patients with implantable ventricular assist devices (VADs) than in other cardiac surgery patients and carries significant mortality. We report our experience with a stepwise approach including aggressive debridement, jet lavage, vacuum assisted closure dressing, and finally coverage with well-vascularized and immune-active omental flaps in VAD patients with infective mediastinitis. We retrospectively collected and analyzed data of patients with continuous flow VAD who underwent plasty with the omental flap because of mediastinitis at Deutsches Herzzentrum Berlin between January 1, 2008 and October 30, 2015. Eight hundred forty-five patients underwent VAD implantation during the study period. Omentoplasty due to infective mediastinitis was performed in 17 cases. Nine had a HeartWare HVAD as left ventricular assist device (LVAD), three patients had two Heart-Ware HVAD as biventricular assist device (BIVAD), four had a HeartMate II LVAD device, and one patient had a Berlin Heart Incor LVAD. The microorganisms most frequently isolated from the sternal wound were Gram-positive Staphylococcus spp. Four cases of bleeding requiring surgical revision were recorded: three of intraabdominal and one of wound bleeding. Eight patients (47%) survived, whereas the other nine patients (53%) died. Sixteen (94%) required intensive care unit admission, and median hospital stay was 21 (1-182) days. Postoperative renal failure requiring dialysis and septic shock requiring vasopressors were associated with hospital mortality (p = 0.009 and p = 0.05, respectively). Early surgical treatment of mediastinitis after VAD implantation with omentoplasty is a valuable strategy in an otherwise dead-end situation. Bleeding should be meticulously controlled in these anticoagulated and fragile patients.

BACKGROUND: In the last 3 years transvaginal hybrid cholecystectomy (TV-ChE) has gained widespread interest as a potential alternative to laparoscopic cholecystectomy. However, substantial doubts about the transvaginal access and possibly associated complaints and complications have been raised. MATERIALS AND METHODS: This was a prospective clinical series of 80 consecutive female patients, nonrandomly chosen and without a control group, who underwent a TV-ChE. All patients were evaluated with special regard to outcome data such as surgical complications and gynecological complaints. Perioperative clinical data were collected and a gynecological examination was performed 3 weeks after surgery as well as a follow-up survey 3 months after surgery. RESULTS: The TV-ChE was performed in all patients without conversion to laparoscopy or open surgery. Two surgical complications occurred (1 urinary bladder injury and 1 case of bleeding). No infections of the surgical wound or any other complications were seen in the gynecological follow-up examination 3 weeks after the operation. After a follow-up of 3 months, 4% of the patients under 50 years of age reported slight and temporary problems after transvaginal cholecystectomy (dyspareunia and episodes of unclear lower abdominal pain), whereas such phenomena were seen in about 9% of women over 50 years of age (P < .05). A 33-year-old woman became pregnant 3 weeks after the operation. CONCLUSIONS: TV-ChE is a safe and less invasive surgical technique. Doubts about this operating technique with regard to an increased risk of infection or surgical complications as well as subsequent gynecological problems seem to be unfounded.
