Background
Anastomotic leakage following colorectal resection remains one of the most significant complications with relevant morbidity and mortality. There is evidence that a higher number of ...stapler firings for rectal division can affect the leak rate in double stapling anastomosis. However, there are no data concerning compression anastomosis. We present our institutional experience addressing this issue.
Design
This is a retrospective review of a prospective institutional database of patients undergoing colonic and rectal resection for benign and malignant indications between January 2008 and December 2014 at the surgical department of the St. John of God Hospital, Vienna. Inclusion criteria were rectal division with linear stapling devices and construction of anastomosis to the rectal stump using a circular stapler or compression device.
Results
Three hundred eighty two (196 female; 51.3%) patients were included. Mean age was 65.8 years (range: 18–95) Indications for the operation included diverticular disease (44.8%), colorectal carcinoma (51.6%), inflammatory bowel disease (1.8%), and adenoma (1.8%). A laparoscopic approach was employed in 334 cases (87.4%); in 170 patients (44.9%), a compression anastomosis was created. One, two, and three or more stapler cartridges were used for rectal division in 58.4, 33.5, and 8.1%, respectively. Male gender, neoadjuvant therapy, rectal cancer as an underlying disease, laparoscopic surgical approach, and duration of operation longer than 200 min are leading causes for the usage of more than one stapler cartridge. Overall leak rate was 4.7% (18/382). The only factor associated with the occurrence of leakage was the use of three or more stapler cartridges for the closure of the rectal stump (
p
= 0.002).
Conclusion
Our data support that multiple stapler firings for rectal division following colorectal resection has a major impact on anastomotic leak rate. Especially in laparoscopic surgery efforts should be made to minimize the number of stapler cartridges used.
Late antibody-mediated rejection (ABMR) is a leading cause of kidney allograft failure. Uncontrolled studies have suggested efficacy of the proteasome inhibitor bortezomib, but no systematic trial ...has been undertaken to support its use in ABMR. In this randomized, placebo-controlled trial (the Bortezomib in Late Antibody-Mediated Kidney Transplant Rejection BORTEJECT Trial), we investigated whether two cycles of bortezomib (each cycle: 1.3 mg/m
intravenously on days 1, 4, 8, and 11) prevent GFR decline by halting the progression of late donor-specific antibody (DSA)-positive ABMR. Forty-four DSA-positive kidney transplant recipients with characteristic ABMR morphology (median time after transplant, 5.0 years; pretransplant DSA documented in 19 recipients), who were identified on cross-sectional screening of 741 patients, were randomly assigned to receive bortezomib (
=21) or placebo (
=23). The 0.5-ml/min per 1.73 m
per year (95% confidence interval, -4.8 to 5.8) difference detected between bortezomib and placebo in eGFR slope (primary end point) was not significant (
=0.86). We detected no significant differences between bortezomib- and placebo-treated groups in median measured GFR at 24 months (33 versus 42 ml/min per 1.73 m
;
=0.31), 2-year graft survival (81% versus 96%;
=0.12), urinary protein concentration, DSA levels, or morphologic or molecular rejection phenotypes in 24-month follow-up biopsy specimens. Bortezomib, however, associated with gastrointestinal and hematologic toxicity. In conclusion, our trial failed to show that bortezomib prevents GFR loss, improves histologic or molecular disease features, or reduces DSA, despite significant toxicity. Our results reinforce the need for systematic trials to dissect the efficiency and safety of new treatments for late ABMR.
To investigate the impact of subretinal drusenoid deposits (SDD) and photoreceptor integrity on global and local geographic atrophy (GA) progression.
Eighty-three eyes of 49 patients, aged 50 years ...and older with GA secondary to age-related macular degeneration (AMD), were prospectively included in this study. Participants underwent spectral-domain optical coherence tomography (SD-OCT) and fundus autofluorescence (FAF) imaging at baseline and after 12 months. The junctional zone and presence of SDD were delineated on SD-OCT and FAF images. Linear mixed models were calculated to investigate the association between GA progression and the junctional zone area, baseline GA area, age, global and local presence of SDD and unifocal versus multifocal lesions.
The area of the junctional zone was significantly associated with the progression of GA, both globally and locally (all P < 0.001). SDD were associated with faster growth in the overall model (P = 0.039), as well as in the superior-temporal (P = 0.005) and temporal (P = 0.002) sections. Faster progression was associated with GA baseline area (P < 0.001). No difference was found between unifocal and multifocal lesions (P > 0.05). Age did not have an effect on GA progression (P > 0.05).
Photoreceptor integrity and SDD are useful for predicting global and local growth in GA. Investigation of the junctional zone is merited because this area is destined to become atrophic. Photoreceptor loss visible on SD-OCT might lead to new structural outcome measurements visible before irreversible loss of retinal pigment epithelium occurs.
Drusen volume (DV) and quantitative autofluorescence (qAF) are potential indicators of progression in age-related macular degeneration (AMD). This prospective and observational study examined the ...association between DV and qAF of the retinal pigment epithelium.
Eighty-eight eyes of 52 patients with early and intermediate AMD were included. The mean follow-up was 9.2 ± 5.6 months, resulting in 312 examinations. DV was extracted from 6 × 6-mm spectral-domain optical coherence tomography scans. qAF was measured using a rotated Delori pattern. The associations between qAF and DV, age, sex, and lens status were investigated using linear mixed models.
Patients' mean age was 75.6 ± 5.0 years (range, 61.0-83.4 years). Sixty-eight eyes (77.3%) were from females. No significant association between DV and qAF was found, neither within the total outer Early Treatment Diabetic Retinopathy Study (ETDRS) grid nor for ETDRS segments six to nine (all P > 0.05). Sex and lens status were not associated with qAF (P = 0.429 and P = 0.213, respectively). A significant association between age and qAF (P = 0.025) was found, indicating a decrease of qAF with age.
Quantification of DV and fundus autofluorescence did not reveal any correlation in early and intermediate AMD. qAF decreased with age, whereas DV increased in about half of the patients. This finding is a quantitative corroboration that fundus autofluorescence and the buildup of drusen are not correlated processes in AMD.
Abstract
Cervical disc arthroplasty is an established procedure, but studies with data on long-term clinical outcome, reoperation for symptomatic adjacent segment degeneration (sASD), and ...degenerative changes based on MRI findings are rare. Thus, a file review was performed and patients with complete documentation of neurological status at preoperative, postoperative, 12 month, 3–4 years follow-up including surgical reports for reoperation with a minimum follow-up of 9 years were included. Final follow-up assessment included a physical examination, assessment of pain levels, Odoms criteria, Neck disability index. The degeneration of each cervical segment at preoperative and at final follow-up was assessed using an MRI. Forty-six out of 68 included patients participated, the mean follow-up was 11 (range 9–15) years, at which 71.7% of patients were free of arm pain, 52.2% of patients were free of neck pain, 63% of patients had no sensory dysfunction, and full motor strength was noted in 95.6% of patients. The clinical success rate was 76.1%, the mean NDI was 12%. Overall repeated procedure rate was 17%, the reoperation rate for sASD was 9%, and removal of CDA was performed in 4%. MRI showed progressive degeneration but no significant changes of SDI from preoperative to final follow-up.
Aim
The study aimed at investigating pregnancy complications, birth outcomes, and postnatal child development in pregnancies of women with inflammatory bowel diseases (IBDs).
Methods
This is an ...uncontrolled retrospective single‐center study between 2014 and 2019. It is a mixed‐method cross‐sectional study using data from (1) electronic patient records and (2) questionnaires and copies of mothers' and children's health booklets. Disease activity and IBD medications were analyzed and related to pregnancy complications, birth outcomes, and postnatal child development using mixed models for statistical analyses.
Results
Fifty live births from 46 patients were included. Disease activity anytime during pregnancy occurred in 56%. Biologics were applied in ca. 25% of pregnancies, mostly only through the second trimester. Pregnancies of mothers with active disease were slightly shorter than those of mothers with inactive disease (37.4 weeks vs. 38.9 weeks). Adverse pregnancy outcomes were reported in 28% of the live births, including small for gestational age in 6%, low birth weight in 18%, and preterm birth in 20%. Postnatal developmental abnormalities and health problems were reported in 26.8% of the children. Mixed model analyses failed to reveal significant associations between IBD activity and IBD medications during pregnancy and pregnancy complications, perinatal birth outcomes, and postnatal child development.
Conclusion
Despite a tendency of shorter pregnancies in patients with active IBD and lower birth weight and birth size in patients with IBD‐related therapy during pregnancy, disease activity and medications did not significantly influence pregnancy, birth, and developmental outcomes.
Perioperative stroke is a devastating complication after coronary artery bypass graft (CABG) surgery, with atherosclerosis of the ascending aorta as important risk factor. During surgical ...manipulation, detachment of plaques can lead to consecutive embolization into brain-supplying arteries. High-pitch computed tomography angiography (HP-CTA) represents a non-invasive imaging modality, which provides the opportunity for comprehensive imaging of the ascending aorta, including plaque detection and advanced characterization. In our present retrospective study on 719 individuals, who had undergone HP-CTA within 6 months prior to CABG, atherosclerotic disease of the ascending aorta was evaluated with respect to perioperative stroke rates. For image analysis, the ascending aorta was divided into a proximal and distal part, consisting of four segments, and evaluated for presence and distribution of calcified and mixed plaques. All patients with perioperative stroke presented with atherosclerotic disease of the ascending aorta. The stroke rate was significantly associated with the presence and extent of atherosclerotic disease. Patients burdened with mixed plaques presented with significantly higher perioperative stroke rates. This study demonstrates that HP-CTA allows accurate evaluation of plaque extent and composition in the ascending aorta, and therefore may improve risk stratification of stroke prior to CABG.
A few weeks before van Gogh admitted himself into a mental hospital in Saint-Rémy in spring 1889 he had written to Gauguin that he wanted to create a “consolatory art for distressed hearts”. From his ...bedroom in the clinic he overlooked an enclosed wheat field. Over the course of a year the seasonal changes inspired Van Gogh to paint a cycle of this wheat field, thereby seeing it as an allegorical representation of the fate of human life, which comforted him.
Soft-tissue conditioning due to posttraumatic oedema after complicated joint fractures is a central therapeutic aspect both pre- and postoperatively. On average, 6-10 days pass until the patient is ...suitable for surgery. This study compares the decongestant effect of vascular impulse technology (VIT) with that of conventional elevation. In this monocentric RCT, 68 patients with joint fractures of the upper (n = 36) and lower (n = 32) extremity were included and randomized after consent in a 1:1 ratio. Variables were evaluated for all fractures together and additionally subdivided into upper or lower extremity for better clinical comparability. Primary endpoint was the time in days from hospital admission to operability. Secondary endpoints were total length of stay, oedema reduction, pain intensity, complications, and revisions. The time from admission until operability was reduced by 1.4 (95% CI - 0.4; 3.1) days in the mITT analysis (p = 0.120) and was statistically significant with 1.7 (95% CI 0.1; 3.3) days in the as-treated sensitivity analysis (p
= 0.038). Significantly less pain and a faster oedema reduction were found in the intervention group. Due to rare occurrences, nothing can be concluded regarding complications and revisions. Administration of VIT therapy did not lead to a significant reduction in time until operability in the whole population but was superior to elevation for soft-tissue conditioning and pain reduction. However, there was a significant reduction by 2.5 days (95% CI 0.7; 4.3) in the subgroup of lower extremity fractures. VIT therapy therefore seems to be a helpful tool in the treatment of posttraumatic oedema after complex joint fractures of the lower and upper extremity, especially in tibial head and lower leg fractures.
