X-ray-guided self-expandable metal stent (SEMS) implantation in oesophageal malignancy as an alternative treatment.

<b><br>Indroduction:</b> Significant dysphagia, aspiration pneumonia, and impossible oral nutrition in patients with unresectable or recurrent gastroesophageal malignancy or bronchial cancer invading the oesophagus with a tracheoesophageal fistula lead to cachexia. Dehiscence of the esophago-jejunal or gastroesophageal anastomosis may cause severe oesophageal haemorrhage. We believe that X-ray-guided oesophageal stent implantation (SEMS) is an alternative palliative method for microjejunostomy or full parenteral nutrition.</br> <b><br>Aim:</b> The aim of this paper was to assess the safety and efficacy of a novel X-ray-guided oesophageal stent implantation technique.</br> <b><br>Materials and methods:</b> This retrospective analysis included 54 patients (35 men and 19 women) treated for malignant dysphagia, gastroesophageal/gastrointestinal anastomotic fistula or bronchoesophageal fistula in two Surgical Units between 2010 and 2019, using a modified intravascular approach to oesophageal stent implantation.</br> <b><br>Results:</b> The presented modified intravascular method of oesophageal stent implantation was successfully performed in all described patients requiring oral nutrition restoration immediately following oesophageal stent implantation. Two patients with oesophageal anastomotic dehiscence died on postoperative days 7 and 9 due to circulatory and respiratory failure. One patient was reimplanted due to a recurrent fistula. Two patients with ruptured thoracic aneurysm and thoracic stent graft implantation due to oesophageal haemorrhage, who were implanted with an oesophageal stent, died on postoperative days 4 and 14.</br> <b><br>Conclusions:</b> The modified intravascular X-ray-guided SEMS technique may be a palliative treatment for patients with unresectable oesophageal malignancies.</br>.

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.

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.

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.

[Oedema of the lower limb in the general practice]. / Obrzek konczyn dolnych w praktyce lekarza rodzinnego.

There is more numerous number of patients in the different age rangesubmit to the general physician. They are transfer to the angiologist or to the vascular surgeon then. The oedema of the lower limb is not only an aestehtic problem. It can be very difficult and in the extreme cases can lead to trobles with move, especially in older patients. The causes of the oedema of theb lower limb can be very deiversed, from trivial caused by the injury to the very serious like phlegmasia coerulea dolens.
