Adaptation of endovascular technique of self-expandable metal esophageal stent implantation in palliative treatment of malignant dysphagia in the course of esophageal and bronchial cancers: A one-center study.

BACKGROUND: Esophageal stent implantation is an alternative for microjejunostomy or total parenteral nutrition in the palliative treatment of malignant dysphagia in the course of esophageal and advanced bronchial cancers infiltrating the esophagus. The procedure of implanting an esophageal self-expanding metal stent (SEMS) is performed with gastroscopic guidance under general anesthesia. OBJECTIVES: To analyze the efficacy and safety of a simplified technique (without gastroscopic guidance in local anesthesia) of esophageal SEMS implantation in patients with malignant dysphagia in the course of esophageal and bronchial cancers. MATERIAL AND METHODS: This is a retrospective analysis of consecutive procedures of uncovered esophageal SEMS implantation performed with a simplified adaptation of the endovascular technique (Seldinger wire) in patients with esophageal and bronchial cancers and poor performance status. The procedures were done in a single surgical center over an 8-year period in 27 patients who were referred from oncology departments with esophageal stenosis confirmed using gastroscopy and who were being treated for malignant dysphagia. The study endpoints were effectiveness (a decrease in dysphagia from grade 3 or 4 to grade 1 after the procedure) and complications related to the procedures (including restenosis and stent migration). RESULTS: In all 27 patients, the SEMS were effectively implanted, enabling enteral nutrition after the procedure. No early complications related to the procedure were observed. A single patient developed restenosis 14 days after the procedure, which required re-stenting. CONCLUSIONS: The simplified method for SEMS implantation described herein may be considered an option in the palliative treatment of patients with malignant dysphagia in the course of esophageal and bronchial cancers and poor performance status, especially in facilities with limited access to endoscopy.

Esophagogastric polyurethane bezoar complicated by stomach wall microperforation and acute peritonitis: case report.

BACKGROUND: Bezoars are collections of indigestible material in the gastrointestinal tract, mostly described in children. Polyurethane "plastobezoars" consisting of composites used in the construction industry are rarely described bezoars formed in the esophagus and stomach, causing gastrointestinal obstruction, usually necessitating gastrectomy. We describe an unusual presentation of polyurethane bezoar with a volcanic rock consistency, that caused gastrointestinal obstruction and perforation of the stomach wall. CASE PRESENTATION: A 39-year-old man, a construction worker, was referred with signs and symptoms of high gastrointestinal obstruction and abdominal pain. Esophagoscopy revealed a foreign body in the esophagus, 20 cm from the incisor line, causing its obstruction. The attempt to collect the material with forceps failed as the material was too hard. Spiral computed tomography visualized a wide, gas-filled esophagus and a large stomach. The patient with symptoms of acute peritonitis was operated. There were several microperforations of the stomach wall, caused by sharp bezoar fragments that filled the upper one-third of the stomach and lower part of the esophagus. After a longitudinal stomach incision, the bezoar was bluntly dissected from the wall and removed, and the stomach microperforations were closed by wall duplication. After the operation, the patient confessed to drinking, of his own free will, a two-component building foam used to seal pipes. The patient started normal feeding on the 4th day and was discharge home. CONCLUSIONS: Polyurethane bezoars may cause stomach wall perforation and acute peritonitis. Computed tomography has limited usefulness in patients with polyurethane bezoars due to their low specific weight.

Analysis of Sexual Disorders in Men with Infrarenal Abdominal Aortic Aneurysm Treated by Stent-Graft or Prosthesis Implantation-A Pilot Study.

Background and objectives: Patients with obstruction or stenosis of the aorta and iliac arteries or with aortic aneurysm, often co-existing with iliac artery aneurysms, suffer from sexual disorders because of insufficient perfusion to the pelvic organs and penis. This is often the cause of visits to a medical doctor's office with reports of a difficult life situation and a problem with the satisfactory completion of sexual intercourse. A low percentage of vascular surgeons or angiologists are prepared to talk about issues related to the hereditary sphere with a patient who qualifies for the treatment of Leriche syndrome or abdominal aortic aneurysm. The aim of this study was to analyze sexual disorders in men with infrarenal abdominal aortic aneurysm treated by stent-graft or prosthesis implantation. Material and methods, Outcomes: 38 patients who completed the IIEF-5 (International Index of Erectile for Men) questionnaire are presented. Initially, 146 qualified for the study after meeting the study inclusion criteria for surgery (Group 1) or for endovascular treatment of abdominal aortic aneurysm (Group 2). Results: In the study, no negative impact of smoking was found; however, over 95% of respondents had been smoking for many years in both groups. Patients who qualified for vascular prosthesis implantation were subject to a more advanced atherosclerotic process involving the aorta and iliac arteries. Patients who qualified for stent-graft implantation were twice as often treated for coronary vessel stenosis. In Group 1, the percentage differences, as shown by questions 1 and 5, were statistically significant (58, i.e., 25%, and 40, i.e., 29%). Conclusions: Education should target medical personnel in terms of conversations with patients, as well as men who are directly affected by this problem, although their partners and families should not be neglected in these activities. The ability to communicate properly allows for an open dialogue on issues that the patient finds difficult, particularly in the field of sexology.

Platelet reactivity in thromboelastometry. Revision of the FIBTEM test: a basic study.

This study aimed to investigate modifications to the FIBTEM test to better assess fibrinogen levels and the quality of fibrin polymerization in citrated blood using Multiplate impedance aggregometry to verify platelet inhibition. Blood samples from 26 healthy volunteers were subjected to thromboelastometry studies (EXTEM/FIBTEM tests) in accordance with the standard study protocol (cytochalasin D) and according to a modified protocol (synthetic IIbIIIa receptor antagonist vs. acetylsalicylic acid [ASA] + synthetic IIbIIIa receptor antagonist instead of cytochalasin D). Independent of thromboelastometry, Multiplate impedance aggregometry was used to assess the degree of restriction by the platelet blocked with the following treatments: (1) cytochalasin D, (2) synthetic IIbIIIa antagonist or (3) ASA + synthetic IIbIIIa antagonist to assess the aggregation response to activation with an agonist (ADP, collagen, thrombin receptor activating peptide-6 [TRAP-6], and arachidonic acid). Via aggregometry, cytochalasin D more weakly inhibited platelet aggregation than simultaneous administration of the -IIbIIIa receptor antagonist with ASA. However, total platelet aggregation inhibition was observed after simultaneous administration of cytochalasin D combined with a synthetic IIbIIIa receptor antagonist. In the thromboelastometry, a significant decrease of the A10, A20 and MCF parameters were observed in the EXTEM/FIBTEM tests after they were modified by the addition of a synthetic IIbIIIa receptor antagonist alone or in combination with ASA. In conclusion, in this Multiplate- and ROTEM-based laboratory approach, a two-way blockade (IIbIIIa-antagonist + cytochalasine D) was sufficient to completely inhibit procoagulant platelet function as observed by aggregometry and thromboelastometry.

A Controlled Trial of the Efficacy of a Training Walking Program in Patients Recovering from Abdominal Aortic Aneurysm Surgery.

BACKGROUND: Major surgical procedures as well as general anesthesia contribute to muscle weakness and posture instability and may result in increased postoperative complications and functional disorders resulting from an elective operation. OBJECTIVES: We aim to state the significance of backward walking as a form of interval march training with patients after abdominal aortic aneurysm surgery. MATERIAL AND METHODS: Sixty-five patients were randomly divided into three subgroups and three various models of physiotherapy were applied. The participants were males, aged 65-75 years, with stable cardiologic status, absence of neurological disorders, and non-symptomatic aneurysm - non-ruptured, no pain complaints and no motor system impairments. The control group had only routine physiotherapy, since therapeutic groups I and II also had walking exercises, forward in group II and backward in group I. Both experimental groups were applied interval training. The patient data analyzed was as follows: hospitalization period-days; 6-min walking test-distance (m), training heart rate (1/min), mean speed (km/h), MET; spirometry test-FVC(L), FEV1(L), FEV1/FVC and PEF(L/s). RESULTS: The hospital stay period in all groups did not vary significantly. Statistical analysis showed that patients with backward walking had a statistically significantly lower reduction of walking distance in the corridor test when compared to the control group (p < 0.05). After the operation, a significant reduction of mean speed in the control group was noted in comparison with both the forward and backward walking groups (p < 0.05). No significant differences were noted between the experimental groups in average walking speed as well as in heart rate in all observed groups. CONCLUSIONS: Physical training applied to patients after major abdominal aortic aneurysm surgery influences sustaining the level of exercise tolerance to a small extent. Both backward and forward walking seem to be alternative methods when compared to classic post-surgery physiotherapy.

Endometriosis of the Vermiform Appendix within a Hernia Sac Infiltrating the Pubic Bone.

Purpose. Appendicular endometriosis mimicking appendicitis is a rare finding. Inguinal tumor in the course of appendicular endometriosis located within an inguinal hernia sac and infiltrating the periosteum of the pubic bone has not yet been described. Case Report. This paper describes a case of a rapidly enlarging, solid, unmovable, very painful upon palpation inguinal tumor, in a 36-year-old nulliparous woman. During surgery, a hard (approximately 4 cm in diameter) tumor infiltrating the periosteum of the right pubic bone and continuous with the inguinal hernia sac was dissected. The distal segment of the vermiform appendix was an element of the dissected tumor. Histological examination revealed endometriosis of the distal vermiform appendix. After 6 months of hormone treatment, she was referred for reoperation due to tumor recurrence. Once again histological examination of the resected tissue revealed endometriosis. There was no further recurrence of the disease with goserelin therapy. In addition to the case report, we present a review of the literature about endometriosis involving the vermiform appendix and the inguinal canal (Amyand's hernia). Conclusion. This case expands the list of differential diagnoses of nodules found in the inguinal region of women.

Trace elements in the wall of abdominal aortic aneurysms with and without coexisting iliac artery aneurysms.

Iliac artery aneurysms (IAA) and abdominal aortic aneurysms (AAA) frequently coexist. It remains unknown whether the content of trace elements in AAA walls depends on the coexistence of IAAs. The aim of this study was to compare the content of selected trace elements in AAA walls depending on the coexistence of IAAs. The content of trace elements was assessed in samples of AAA walls harvested intraoperatively in 19 consecutive patients. In the studied group, coexisting IAAs were diagnosed in 11 out of the 19 patients with AAA. The coexistence of IAAs was associated with a slightly lower content of nickel (0.28 (0.15-0.40) vs. 0.32 (0-0.85) mg/g; p = 0.09) and a significantly higher content of cadmium (0.71 (0.26-1.17) vs. 0.25 (0.20-0.31) mg/g; p = 0.04) in AAA walls. The levels of the remaining studied elements, copper, zinc, manganese, magnesium and calcium, were comparable. The elevated levels of cadmium in the walls of AAA coexisting with IAAs may suggest an impact of the accumulation of this trace element on the greater damage of the iliac artery wall.

Assessment of subclinical acute kidney injury after abdominal aortic aneurysm surgery using novel markers: L-FABP and H-FABP.

BACKGROUND: One of the most severe complications of repair surgery for abdominal aortic aneurysms (AAA) is acute kidney injury (AKI). Even small rises in serum creatinine are associated with increased mortality. The aim of this study was to assess the dynamics of AKI after elective AAA surgery using novel markers. METHODS: The study group consisted of 22 patients with AAA. We measured urinary liver- (u-L-FABP) and heart-type fatty acid-binding proteins (u-H-FABP) before, during and within 3 days after surgery. RESULTS: We found an abrupt and significant elevation of both urine FABPs normalized to urinary creatinine; u-L-FABP reached its peak value 2 hours after aortic clamp release {137.79 (38.57-451.79) vs. 9.94 (6.82-12.42) ng/mg baseline value, p<0.05; values are medians (lower-upper quartile)}. The peak value of u-H-FABP was reported 72 hours after aortic clamp release {16.462 (4.182-37.595) vs. 0.141 (0.014-0.927) ng/mg baseline value, p<0.05}. The serum creatinine level did not changed significantly during the investigation period. CONCLUSIONS: The significant rise of both u-L-FABP and u-H-FABP after AAA surgery indicates renal proximal and distal tubule injury in this population. Our results suggest that, after AAA surgery, the distal tubules could be more affected than the proximal ones. u-FABPs could serve as sensitive biomarkers of kidney tubular injury and may allow to detect the very early phases of AKI.

Intraluminal thrombus thickness is not related to lower concentrations of trace elements in the wall of infrarenal abdominal aortic aneurysms.

BACKGROUND: Intraluminal thrombus (ILT) formation plays a significant role in the progression of infrarenal abdominal aortic aneurysms (AAA). Potentially, as ILT thickness increases the availability of trace elements in the aneurysm wall could decrease thereby leading to oxidative stress and intensifying pro-inflammatory cytokine generation. AIM: To determine if thrombus thickness is related to the concentration of trace elements in the wall of infrarenal AAA. PATIENTS AND METHODS: The concentrations of trace elements in the wall of the aneurysm sack and ILT obtained from 19 consecutive patients during surgery for infrarenal AAA were determined using emission spectrometry. RESULTS: The concentrations of magnesium, zinc, manganese, and lead in the wall of AAA were significantly greater than in the ILT. Only the concentration of copper was lower in the AAA wall compared with the thrombus. The concentration of calcium, phosphorus, zinc, lead, copper, and magnesium increased with ILT thickness. The concentrations of no other trace elements in the wall of AAA were found to be related to the ILT thickness. CONCLUSIONS: Intraluminal thrombus thickness is not associated with a lower concentration of trace elements in the wall of the infrarenal AAA. Thus, the intraluminal thrombus participates in the progression of AAA by mechanisms independent of trace element supply to the wall of the aneurysm sack.

Purulent cutaneous fistula: as the first symptom of the late aortic stent-graft infection-a case report and review of the literature.

Purpose. Aortic stent-graft infection with fistula formation is a rare complication with high mortality rate when treated surgically by stent-graft removal. We report a case of a patient with aortic stent-graft infection, prosthetic-duodenal, and prosthetic-cutaneous fistulas operated without the removal of an infected prosthesis and ineffectively tailored antibiotic therapy. Case Report. A 66-year-old patient with high cardiovascular risk and endovascular stent-graft implantation developed a symptomatic infection of the aortic stent graft 42 months after procedure. It was manifested by iliolumbar muscle abscess and two fistulas: prosthetic cutaneous and prosthetic duodenal. The prosthetic-duodenal fistula was excised and separated from the prosthesis. The perforation within the duodenum was closed in layers. Iliolumbar abscess was removed and drainage was effected .The stent graft was left. The patient received tailored antibiotic therapy. He was readmitted to hospital after 4 weeks with symptoms of infection and leakage of pus discharge in the lumbar area. Despite the antibiotic therapy, the total parenteral nutrition of the patient's clinical status and malnutrition deteriorated and he died of cardiac arrest. Conclusion. The presented case confirms that leaving off of the infected stent graft in the patient with severe comorbidity and treated with a tailored antibiotic therapy may not be effective.

Endothelium injury and inflammatory state during abdominal aortic aneurysm surgery: scrutinizing the very early and minute injurious effects using endothelial markers - a pilot study.

INTRODUCTION: One of the most severe complications of repair surgery for abdominal aortic aneurysms (AAA) is acute kidney injury (AKI). Acute kidney injury is an inflammatory process whose pathogenesis involves endothelial cells (EC). The aim of this study was to assess the dynamics of endothelium injury markers measured during elective AAA surgery which might confirm the inflammatory character of AKI. MATERIAL AND METHODS: The study group consisted of 14 patients with AAA. We measured plasma soluble forms of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, P-selectin as well as the levels of von Willebrand factor (vWF) before, during (including intra-abdominal vein levels before and after aortic clamp removal) and within 2 days after surgery. RESULTS: We have found a biphasic response of ICAM-1, VCAM-1 and P-selectin with an initial fall and subsequent rise. However, only VCAM-1 changes were significant compared to its baseline value. The maximum decrease of VCAM-1 was observed in the renal vein 5 min after aortic clamp removal (335.42 ±129.63 ng/ml vs. 488.90 ±169.80 ng/ml baseline value, p < 0.05), and the highest rise 48 h after aortic clamp removal (721.46 ±333.99 vs. baseline, p < 0.05). CONCLUSIONS: Vascular cell adhesion molecule-1 turned out to be the most sensitive indicator of EC injury and inflammatory status after AAA surgery. During AAA surgery, soluble forms of P-selectin, ICAM-1 and VCAM-1 demonstrate a biphasic response with an initial fall and subsequent rise. These soluble forms could have a modulatory effect on the development of inflammation.

Inflammatory markers in patients with internal carotid artery stenosis.

INTRODUCTION: Available reports underline the significance of the inflammatory process in the development, progression and destabilisation of atherosclerotic plaques in the internal carotid artery (ICA). The aim of this study was to evaluate the relationship between the degree of ICA stenosis, ultrasound plaque morphology and serum concentration of selected inflammatory markers. MATERIAL AND METHODS: Sixty-five patients with ICA stenosis > 50% (39 symptomatic) and 30 healthy volunteers were enrolled in the study. Clinical, neurological examination and laboratory evaluation (leucocyte count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), fibrinogen, tumour necrosis factor-α (TNF-α), interleukins (1ß, 6 and 10), anti-cytomegalovirus IgG antibody titre) were performed. Stenosis grade ≥ 70%, ulcerations on the plaque surface and a hypoechoic (or predominantly hypoechoic) structure of the plaque, obtained by colour-coded duplex examination, were accepted as the characteristics of unstable stenoses. RESULTS: Unstable ultrasound features of ICA stenosis were found significantly more often in symptomatic than in asymptomatic patients (71.79% vs. 30.71% for stenosis degree ≥ 70%, p = 0.001 and 61.23% vs. 38.46% for unstable plaque morphology, p = 0.01). Patients with ICA stenosis had significantly higher serum concentrations of interleukin-6, fibrinogen, ESR and higher CRP values than the individuals from the control group (p = 0.001, p = 0.009, p = 0.036, p = 0.009 respectively). Patients with unstable plaques structure had significantly higher concentrations of TNF-α, interleukin-6, fibrinogen, higher number of leukocytes, monocytes and higher CRP values than patients with stable plaques (p = 0.008, p = 0.049, p = 0.012, p = 0.0002, p = 0.006, p = 0.0003 respectively). No significant differences in above-mentioned parameters between the groups with stenosis < 70% and ≥ 70% were found. CONCLUSIONS: There is a relationship between the activity of the selected inflammatory markers in serum and atherosclerotic unstable internal carotid artery stenosis. There is no relationship between serum concentration of inflammatory markers and degree of carotid artery stenosis.

Acute kidney injury after abdominal aortic aneurysm surgery: detailed assessment of early effects using novel markers.

INTRODUCTION:  One of the most severe complications of repair surgery for abdominal aortic aneurysms (AAA) is acute kidney injury (AKI). Even small rises in serum creatinine after surgery are associated with increased mortality. OBJECTIVES:  The aim of the study was to assess the dynamics of AKI after elective AAA surgery using novel markers. PATIENTS AND METHODS:  The study group consisted of 14 patients with AAA. We measured serum neutrophil gelatinase­associated lipocalin (NGAL) before, during (including intra­abdominal vein levels before and after removal of aortic clamp), and within 2 days after surgery.  Moreover, we assessed urinary NGAL, interleukin 18 (IL­18), and liver­type fatty acid­binding protein (L­FABP) before, during, and within 3 days after surgery. RESULTS:  We observed a marked but nonsignificant increase in serum NGAL directly after clamp removal (75.21 ±55.83 vs. 46.37 ±21.60 ng/ml baseline value, P >0.05) and significantly elevated plasma NGAL at 2 hours (91.54 ±76.54 vs. baseline, P <0.05), 12 hours (100.78 ±44.92 vs. baseline, P <0.05) and 24 hours (89.46 ±94.18 vs. baseline, P <0.05) after clamp release. There was also significant elevation of urinary IL­18 at 2 hours (51.60 [12.12-527.16] vs. 25.99 [9.34-187.80] pg/ml at baseline, P <0.05); L­FABP at 2 hours (47.10 [5.40-500.00] vs. 5.50 (2.20-27.20) ng/ml at baseline, P <0.05) and 12 hours (39.00 [5.20-500.00] vs. baseline, P <0.05); NGAL at 12 hours (20.75 [5.00-176.10] vs. 5.85 [1.40-16.00] ng/ml at baseline, P <0.05) and 24 hours (13.95 [3.90-163.30] vs. baseline, P <0.05) after clamp release. CONCLUSIONS:  Elective AAA surgery may induce AKI. Novel markers can facilitate early detection of AKI, thus allowing to start therapy at an appropriate time point.

Ankle-brachial pressure index estimated by laser Doppler in patients suffering from peripheral arterial obstructive disease.

Ankle-brachial index (ABI) measurements are widely used for evaluating the functional state of circulation in the lower limbs. However, there is some evidence that the value of ABI does not accurately reflect the degree of walking impairment in symptomatic patients with peripheral arterial obstructive disease (PAOD). We investigated the diagnostic value of ABI estimated by means of laser Doppler flowmetry (IT) for evaluating limb ischemia. We wanted to know whether laser Doppler could be more sensitive than the Doppler method in predicting walking capacity in patients with stable intermittent claudication. We analyzed a group of 30 patients with intermittent claudication (Fontain II, II/III) who were admitted for reconstructive treatment. There were 21 men and 9 women, aged 46-74 (mean 61) years. All patients underwent the treadmill test, and pain-free walking distances were measured. In each patient, we measured ABI using the two different methods: Doppler ultrasound device (ABI-Doppler) and laser Doppler (ABI-laser Doppler). The claudication distances were 25-200 m (mean 73 +/- 50.2 m). ABI-Doppler was 0.2-0.7 (0.582 +/- 0.195). ABI-laser Doppler measurements were 0.581 (+/-0.218). A correlation was found between ABI-Doppler and claudication distance (r = 0.46, P = 0.009). Also, ABI-laser Doppler values significantly correlated with claudication distances (r = 0.536, P = 0.002). The ABI evaluated by laser Doppler correlated well with claudication distances in patients with PAOD. Comparison of Doppler and laser Doppler measurements used for determining ABI showed that both methods have similar predictive power for walking capacity; however, higher correlation was observed between claudication distances and ABI measured by laser Doppler flowmetry. ABI-laser Doppler measurements are easier, are quicker, and seem to be better suited for noncompliant patients. Further investigation should be undertaken to determine whether laser Doppler is superior to the Doppler method in advanced occlusive arterial disease.

Sapheno-femoral junction pathology: molecular mechanism of saphenous vein incompetence.

A molecular mechanism responsible for varicose vein occurrence was investigated. The role of potential cell cycle regulator p21 and programmed cell death in the pathology leading to the proximal long saphenous vein (LSV) incompetence was investigated. Proximal LSV specimens were obtained from 40 patients with primary varicose veins who had undergone crossectomy. The expression of the p21, p53, and fas encoding genes was investigated by the means of real-time RT-QPCR. Immunostaining for gene product presence, proliferating cell nuclear antigen (PCNA), and apoptotic cells (TUNEL assay) was carried out. The results were compared to the control healthy vein specimens and correlated with pathologic examination findings (of the valve and vein structure). A significant increase in p21, p53, and fas mRNA expression were reported in the proximal incompetent veins. The expression of p21 correlated with expression of p53 (r = 0.658; p<0.05) and negative correlation between media apoptotic index and p21 mRNA expression was found (r = -0.493; p<0.05). Decrease in the muscular component within the media and disturbances of the local structure in the incompetent LSVs were reported. Fas overexpression did not correlate with p53 expression level and did not correlate with apoptotic cell number in the respective vein layers. PCNA-positive cells were present more frequently in the media of the control veins, especially in young subjects. Apoptosis downregulation, cell cycle inhibition and smooth muscle cell hypertrophy are important factors influencing vein wall disturbances related to sapheno-femoral junction incompetence.
