Timing and Outcomes After Coronary Angiography Following Out-of-Hospital Cardiac Arrest Without Signs of ST-Segment Elevation Myocardial Infarction.

Background: There is broad consensus that resuscitated out-of-hospital cardiac arrest (OHCA) patients with ST-segment elevation myocardial infarction (STEMI) should receive immediate coronary angiography (CAG); however, factors that guide patient selection and optimal timing of CAG for post-arrest patients without evidence of STEMI remain incompletely described.

Objective: We sought to describe the timing of post-arrest CAG in actual practice, patient characteristics associated with decision to perform immediate vs. delayed CAG, and patient outcomes after CAG.

Finding the Best Lighting Mode for Daguerreotype, Ambrotype, and Tintype Photographs and Their Deterioration on the Cruse Scanner Based on Selected Methods.

In the digital heritage field, the accurate reproduction of hard-to-photograph items, such as daguerreotypes, ambrotypes, and tintypes, is an ongoing challenge. Industrial contactless sensors offer the potential to improve the quality of scanned images, but their capabilities and limitations have not been fully explored. In our research, a dataset of 48 scans was created using the hi-tech industrial contactless sensor CRUSE.

Associations between matrix metalloproteinase, tissue inhibitor of metalloproteinase and collagen expression levels in the adjacent rectal tissue of colorectal carcinoma patients.

As the commonest type of cancer in Europe and the third most common type of cancer worldwide, colorectal carcinoma (CRC) poses a challenge for numerous scientific studies. At present, the cause of this disease is remains to be elucidated, but early diagnosis is only one solution to prevent serious health complications. As a structural scaffold, the extracellular matrix (ECM) is in direct contact with tumour cells and significantly interferes with tumour progression.

Clinical factors associated with significant coronary lesions following out-of-hospital cardiac arrest.

Objectives: Out-of-hospital cardiac arrest (OHCA) afflicts >350,000 people annually in the United States. While postarrest coronary angiography (CAG) with percutaneous coronary intervention (PCI) has been associated with improved survival in observational cohorts, substantial uncertainty exists regarding patient selection for postarrest CAG. We tested the hypothesis that symptoms consistent with acute coronary syndrome (ACS), including chest discomfort, prior to OHCAs are associated with significant coronary lesions identified on postarrest CAG.

The Difficult Path to Correct Diagnosis of Hepatolithiasis: A Case Report.

Hepatolithiasis is a benign disease, where stones are localized proximal to the confluence of hepatic ducts. The clinical picture may differ depending on whether the stones cause complete, partial, or intermittent biliary obstruction. The course can vary from asymptomatic to fatal, thus, early diagnosis and treatment is critical for a good prognosis.

Mucosa plication reinforced colorectal anastomosis and trans-anal vacuum drainage: a pilot study with preliminary results.

Dehiscence of colorectal anastomosis is a serious complication that is associated with increased mortality, impaired functional and oncological outcomes. The hypothesis was that anastomosis reinforcement and vacuum trans-anal drainage could eliminate some risk factors, such as mechanically stapled anastomosis instability and local infection. Patients with rectal cancer within 10 cm of the anal verge and low anterior resection with double-stapled technique were included consecutively.

Colorectal anastomosis dehiscence: a call for more detailed morphological classification.

Introduction: A proactive approach is recommended in colorectal anastomosis leak treatment, and early diagnosis is very important. Early postoperative endoscopy would allow rapid diagnosis of anastomotic pathologies and consequent prompt intervention according to anastomotic disruption morphology.

Aim: To evaluate the effectiveness of close endoscopic follow-up of all patients (including asymptomatic ones) in improving diagnosis of acute leak (AL) and reducing its complications.

Laparoscopic versus open liver resections for colorectal cancer liver metastases: short term results.

Introduction: Analysis and comparison of short-term results of laparoscopic liver resections (LLR) and open liver resections (OLR) for colorectal cancer liver metastases (CRCLM).

Methods: Retrospective analysis of patients operated for CRCLM in the time period from May 2007 to May 2019 (12 years) at the department of surgery, University Hospital Hradec Králové and University Hospital Královské Vinohrady.

Results: 206 liver resections were performed; 167 (81.

The Time Between Chemoradiation and Surgery for Rectal Carcinoma Negatively Influences Mesorectal Excision Quality.

Total mesorectal excision quality (TMEq) is a prognostic factor associated with local recurrence in rectal adenocarcinoma. Neoadjuvant chemoradiotherapy (NCRT) reduces the risk of tumor recurrence, but may compromise TMEq. The time between NCRT and surgery (TTS) and how it influences TMEq and tumor control were evaluated.

Totally Laparoscopic ALPPS: Bilobar Procedure with Preservation of the S3 Portobiliary Triad.

Background: A laparoscopic approach for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) would have the potential to decrease morbidity and mortality rates, as similarly observed with laparoscopic liver surgery. METHODS: A 54-year-old woman with stage IV rectal cancer (cT3dN1M1) was indicated for the 'liver-first' approach. The patient presented with a massive bilobar metastatic liver involvement, including S4.

Distribution of metastases in mesorectum is unpredictable: Metastases do not respect tumor localization even in small non-circumferential rectal cancers.

Introduction: Low anterior resection with total mesorectal excision (TME) is the gold standard for surgical treatment of rectal carcinoma. The radicality of this procedure is negatively counterbalanced by morbidity, lethality, and numerous other complications. Local excision would appear to be an attractive alternative, but its radicality is disputable due to risk of undetected metastasis to the mesorectum.

Histopathologic Features are more Important Prognostic Factors than Primary Tumour Location in Gastro-oesophageal Adenocarcinoma Treated with Preoperative Chemoradiation and Surgery.

The aim of present study was to evaluate the impact of primary tumour location and other factors on the outcome of preoperative chemoradiation followed by surgery in adenocarcinomas of distal oesophagus, gastro-oesophageal junction and stomach. We retrospectively reviewed the institutional patient database. The therapeutic response was re-evaluated as a percentage of residual tumor cells in surgical resection specimens.

[An uncommon case of purulent mesenteric lymphadenitis].

The authors present a case of a middle-aged female with large isolated mesenteric lymphadenitis. Abdominal ultrasonography undertaken as a preventive assessment revealed a solid tumour mass in the left mesogastrium, sized 70x55x55 mm. A solid abdominal tumour such as a GIST or sarcoma was considered and the patient underwent elective laparoscopic surgery.

[Technical background of data collection for parametric observation of total mesorectal excision (TME) in rectal cancer].

Introduction: Improvement in any human activity is preconditioned by inspection of results and providing feedback used for modification of the processes applied. Comparison of experts experience in the given field is another indispensable part leading to optimisation and improvement of processes, and optimally to implementation of standards. For the purpose of objective comparison and assessment of the processes, it is always necessary to describe the processes in a parametric way, to obtain representative data, to assess the achieved results, and to provide unquestionable and data-driven feedback based on such analysis.

[Parametric monitoring of the quality of total mesorectal excision and surgical treatment of rectal carcinoma results of a multicenter study].

Introduction: Tumour size and the quality of its complete surgical removal are the main prognostic factors in rectal cancer treatment. The number of postoperative local recurrences depends on whether the mesorectum has been completely removed - total mesorectal excision (TME) - and whether tumour-free resection margins have been achieved. The surgery itself and its quality depend on the accuracy of preoperative diagnosis and detection of risk areas in the rectum and mesorectum, on the surgeons skills, and finally on pathological assessment evaluating whether complete tumour excision has been accomplished including circumferential margins of the tumour, and whether mesorectal excision is complete.

Neoadjuvant chemoradiotherapy of rectal carcinoma : Baseline hematologic parameters influencing outcomes.

Background: The link between the blood count and a systemic inflammatory response (SIR) is indisputable and well described. Pretreatment hematological parameters may predict the overall clinical outcomes in many types of cancer. Thus, this study aims to systematically evaluate the relationship between baseline blood count levels and treatment response in rectal cancer patients treated with neoadjuvant chemoradiotherapy.

Impact of postoperative complications on clinical and economic consequences in pancreatic surgery.

Purpose: Patients who develop complications consume a disproportionately large share of available resources in surgery; therefore the attention of healthcare funders focuses on the economic impact of complications. The main objective of this work was to assess the clinical and economic impact of postoperative complications in pancreatic surgery, and furthermore to assess risk factors for increased costs.

Methods: In all, 161 consecutive patients underwent pancreatic resection.

Intra-abdominal drainage following pancreatic resection: A systematic review.

Aim: To study all the aspects of drain management in pancreatic surgery.

Methods: We conducted a systematic review according to the PRISMA guidelines. We searched the Cochrane Central Registry of Controlled Trials, EMBASE, Web of Science, and PubMed (MEDLINE) for relevant articles on drain management in pancreatic surgery.

[Current status in the treatment of rectal cancer in the Czech Republic regarding the rate of complete pathological response after neoadjuvant therapy--PATOD C20 study 2011-2012].

Introduction: Deciding on the strategy in rectal cancer´s treatment requires a complex and multidisciplinary approach. The primary rectal resection is indicated in early stages, while locally advanced tumors should be pretreated by one of the modes of neoadjuvant (chemo) radiotherapy. The main goal of this study was to explore the therapeutic strategy in patients with rectal cancer in the Czech Republic.

Endovascular Management of Acute Embolic Occlusion of the Superior Mesenteric Artery: A 12-Year Single-Centre Experience.

Purpose: Retrospective evaluation of 12-year experience with endovascular management of acute mesenteric ischemia (AMI) due to embolic occlusion of the superior mesenteric artery (SMA).

Materials And Methods: From 2003 to 2014, we analysed the in-hospital mortality of 37 patients with acute mesenteric embolism who underwent primary endovascular therapy with subsequent on-demand laparotomy. Transcatheter embolus aspiration was used in all 37 patients (19 women, 18 men, median age 76 years) with embolic occlusion of the SMA.

CT/MRI pelvimetry as a useful tool when selecting patients with rectal cancer for transanal total mesorectal excision.

Background: The quality of a total mesorectal excision (TME) is one of the most important prognostic factors for local recurrence of rectal carcinoma. The aim of this study was to clarify the manner in which lesser pelvis dimensions affect the quality of TME via the transabdominal approach, while simultaneously defining the criteria for selecting patients most likely to have Grade 3 TME outcomes for a transanal approach using the TaTME technique.

Methods: An analysis from the registry was conducted using 93 of total 198 patients with rectal cancer of the mid- and lower third of the rectum who underwent: (1) a low anterior resection, (2) an ultra-low resection with coloanal anastomosis, or (3) an intersphincteric rectal resection, all with total mesorectal excision.

DRAPA trial--closed-suction drains versus closed gravity drains in pancreatic surgery: study protocol for a randomized controlled trial.

Background: The morbidity of pancreatic resection remains high, with pancreatic fistula being the most common cause. The important question is whether any postoperative treatment adjustment may prevent the development of clinically significant postoperative pancreatic fistulae. Recent studies have shown that intraabdominal drains and manipulation using them are of great importance.

Small carcinomas involving less than one-quarter of the rectal circumference: local excision is still associated with a high risk of nodal positivity.

Aim: A study was carried out to determine the relationship between mesorectal lymph nodal involvement and T stage in a group of patients with a rectal cancer involving less than one-quarter of the rectal circumference, such as might be selected for local excision.

Method: The data of patients having rectal resection between 2010 and 2014 were prospectively entered in a rectal carcinoma registry. A model for describing tumours involving less than one quadrant of the rectal circumference was created to facilitate the evaluation process.
