In colorectal surgery, anastomotic leakage is a serious complication, leading to higher postoperative morbidity and mortality. The aim of this study was to evaluate the accuracy of serum and ...intraperitoneal C-reactive protein (CRP) in early diagnostics of anastomotic leakage on the first four postoperative days after colorectal surgery. From January to October 2019, fifty-nine patients with colorectal carcinoma were operated on, with formation of primary anastomosis. Anastomotic leakage was diagnosed in eight patients. Comparing the levels of serum and intraperitoneal CRP, our study showed that serum CRP was a better predictor of anastomotic leakage. Serum CRP levels lower than 121 mg/L on postoperative day 4 were predictive of good healing of anastomosis.
(1) Background: Chronic spontaneous urticaria (CSU) has been linked to the dysbiosis of the gut microbiota. Furthermore, various studies have highlighted the anti-inflammatory properties of ...short-chain fatty acids (SCFAs), whose production is primarily regulated by the gut microbiota. However, only a few studies have investigated the role of major SCFA producers, such as
, in skin inflammatory diseases. (2) Goal: This study aimed to compare the abundance of
between CSU patients and healthy controls (HCs). (3) Material and methods: In this case-control study, 16S rRNA sequencing was performed to compare the composition of the gut microbiome between 22 CSU patients and 23 HCs. (4) Results: Beta-diversity revealed significant clustering (
< 0.05) between the CSU patients and HCs. Alpha diversity in the CSU group was significantly decreased according to the Evenness index (
< 0.05). The linear discriminant analysis effect size (LEfSe) identified the significant depletion of the
family in CSU patients. (5) Conclusion: Our study revealed the dysbiosis of the gut microbiota in CSU patients, including decreased levels of
members, responsible for SCFA production, suggesting that SCFAs may contribute to immune dysfunction in the pathogenesis of CSU. We speculate that the modulation of SCFAs could serve as a prospective additional option in CSU treatment.
Recently, some new morphological features of colorectal cancer have been discovered as important prognostic factors; in this paper, we study the relationship between tumor budding (TB) and tumor ...deposits (TDs).
The retrospective cohort study included 90 patients with pathohistologically confirmed stage III CRC who were treated with radical surgical resection. All hematoxylin and eosin (H and E)-stained slides from each patient were reviewed, and histological parameters were recorded. The samples were divided into two groups with similar sizes: a group without TDs (N = 51) and a control group with TDs (N = 39). The presence and TB grade were further analyzed in these groups and compared with other clinical and histological features.
The prevalence of TB in the investigated cohort was unexpectedly high (94.4%). Overall, there were 23 (25.6%) Bd1, 20 (22.2%) Bd2, and 47 (52.2%) Bd3 cases. The presence of TDs was significantly associated with a higher number of TB (
< 0.001, OR 16.3) and, consequently, with a higher TB grade (
= 0.004, OR 11.04). A higher TB grade (
= 0.001, HR 2.28; 95% CI 1.93-4.76) and a growing number of TDs (
= 0.014, HR 1.52; 95% CI 1.09-2.1) were statistically significantly associated with shorter survival.
TDs appear more often in patients with higher TB grades in stage III CRC. A higher TB grade and a growing number of TDs were statistically significantly associated with shorter overall survival. These results could give additional emphasis to the importance of TB as an adverse prognostic factor since a strong relationship with TDs has been demonstrated.
Hypofractionated post-prostatectomy radiotherapy is emerging practice, however with no randomized evidence so far to support it's use. Additionally, patients with persistent PSA after prostatectomy ...may have aggressive disease and respond less well on standard salvage treatment. Herein we report outcomes for conventionally fractionated (CFR) and hypofractionated radiotherapy (HFR) in patients with persistent postprostatectomy PSA who received salvage radiotherapy to prostate bed.
Single institution retrospective chart review was performed after Institutional Review Board approval. Between May 2012 and December 2016, 147 patients received salvage postprostatectomy radiotherapy. PSA failure-free and metastasis-free survival were calculated using Kaplan-Meier method. Cox regression analysis was performed to test association of fractionation regimen and other clinical factors with treatment outcomes. Early and late toxicity was assessed using Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.
Sixty-nine patients who had persistent PSA (≥ 0.1 ng/mL) after prostatectomy were identified. Median follow-up was 67 months (95% CI 58-106 months, range, 8-106 months). Thirty-six patients (52.2%) received CFR, 66 Gy in 33 fractions, 2 Gy per fraction, and 33 patients (47.8%) received HFR, 52.5 Gy in 20 fractions, 2.63 Gy per fraction. Forty-seven (68%) patients received androgen deprivation therapy (ADT). 5-year PSA failure- and metastasis-free survival rate was 56.9% and 76.9%, respectively. Thirty patients (43%) experienced biochemical failure after salvage radiotherapy and 16 patients (23%) experienced metastatic relapse. Nine patients (13%) developed metastatic castration-resistant disease and died of advanced prostate cancer. Median PSA failure-free survival was 72 months (95% CI; 41-72 months), while median metastasis-free survival was not reached. Patients in HFR group were more likely to experience shorter PSA failure-free survival when compared to CFR group (HR 2.2; 95% CI 1.0-4.6, p = 0.04). On univariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (CFR vs HFR, HR 2.2, 95% CI 1.0-4.6, p = 0.04), first postoperative PSA (HR 1.02, 95% CI 1.0-1.04, p = 0.03), and concomitant ADT (HR 3.3, 95% CI 1.2-8.6, p = 0.02). On multivariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (HR 3.04, 95% CI 1.37-6.74, p = 0.006) and concomitant ADT (HR 4.41, 95% CI 1.6-12.12, p = 0.004). On univariate analysis, factors significantly associated with metastasis-free survival were the first postoperative PSA (HR 1.07, 95% CI 1.03-1.12, p = 0.002), seminal vesicle involvement (HR 3.48, 95% CI 1.26-9.6,p = 0.02), extracapsular extension (HR 7.02, 95% CI 1.96-25.07, p = 0.003), and surgical margin status (HR 2.86, 95% CI 1.03-7.97, p = 0.04). The first postoperative PSA (HR 1.04, 95% CI 1.00-1.08, p = 0.02) and extracapsular extension (HR 4.24, 95% CI 1.08-16.55, p = 0.04) remained significantly associated with metastasis-free survival on multivariate analysis. Three patients in CFR arm (8%) experienced late genitourinary grade 3 toxicity.
In our experience, commonly used hypofractionated radiotherapy regimen was associated with lower biochemical control compared to standard fractionation in patients with persistent PSA receiving salvage radiotherapy. Reason for this might be lower biological dose in HFR compared to CFR group. However, this observation is limited due to baseline imbalances in ADT use, ADT duration and Grade Group distribution between two radiotherapy cohorts. In patients with persistent PSA post-prostatectomy, the first postoperative PSA is an independent risk factor for treatment failure. Additional studies are needed to corroborate our observations.
Introduction. Gastrointestinal angiosarcomas are rare and represent less than 1% of all gastrointestinal tract malignancies, with most occurring in the stomach and small intestine. Occurrence in the ...colorectal segments is considered extremely rare. Case Report. We describe the case of a 61-year-old male with multiple primary angiosarcomas of the colon who presented with fever and abdominal pain. The patient was initially hospitalized and treated as having an infectious disease. A multislice computed tomography (MSCT) scan revealed multiple soft tissue tumors in the region of the left iliopsoas and gluteus medius muscles. After developing hematochezia, a colonoscopy was performed which found an ulcerated tumor in the sigmoid colon. The small tissue biopsy taken during the procedure presented diagnostic difficulties and was given a preliminary diagnosis of gastrointestinal stromal tumor (GIST). Examination of the resected colon segment and surrounding fat tissue revealed four separate tumors. Microscopically, the tumors were composed of solid sheets of spindle and epithelioid neoplastic cells with prominent nucleoli and numerous mitotic figures and immunohistochemically positive for ERG, CD31, CD34, vimentin, and CD117, while negative for CK7, CK20, CD20, CD3, CD45, TTF-1, PAN-CK, ALK, Mpox, S-100, and DOG1, leading to the final diagnosis of multiple colonic angiosarcomas. The patient’s condition declined rapidly and he passed away from multiple organ failures 60 days after initial hospitalization. Conclusion. Both clinical and pathological diagnoses of colorectal angiosarcoma are challenging. Patients are present with nonspecific symptoms leading to mismanagement and late diagnosis. A definitive pathological diagnosis relies on immunohistochemical staining for endothelial markers. Misdiagnosis as poorly differentiated adenocarcinoma or GIST is possible in limited tissue biopsies.
This research looks at the connection between psychological stress and the prevalence of hand eczema (HE) among physicians and dentists (surgeons, non-surgeons).
This cross-sectional field study ...involved 185 participants: physicians (surgeons, non-surgeons), dentists (surgeons, non-surgeons) and controls. Hand lesions were examined using the Osnabrueck Hand Eczema Severity Index (OHSI), and participants answered the Nordic Occupational Skin Questionnaire (NOSQ) and Perceived Stress Scale (PSS). Patch tests were performed using commercial contact allergens.
The estimated prevalence of HE (self-reported) was 43.9% (physicians 44.6%; dentists 43.2%). HE was significantly more reported by surgeons than controls (
< 0.004; V = 0.288). Degrees of perceived stress (PSS) did not differ significantly between the groups, though physicians non-surgeons most exhibited high stress (50%), and physicians surgeons most exhibited low stress (22.5%). High stress was associated with 2.5 higher odds for self-reported HE (
= 0.008). Low stress was greater among physicians/dentists who did not report eczema (41.0% vs. 24.6%); moderate stress was more common among those who reported eczema (72.3% vs. 51.8%;
= 0.038; V = 0.210).
Since high stress levels may negatively influence physicians'/dentists' work and quality of life, measures to decrease stress could be introduced into the treatment of healthcare workers who are prone to it.
- The aim of the study was to reevaluate the safety and feasibility of discharge 24 h after elective uncomplicated laparoscopic cholecystectomy. Since the introduction of laparoscopic cholecystectomy ...in our hospital, the minimum postoperative stay was considered to be two days based on surgeons' experience. The study included 337 operations performed by 21 surgeons during 2016 in the Sestre milosrdnice University Hospital Centre. Conversion to open technique and cases of acute cholecystitis were excluded, while 15 patients had insufficient postoperative data. The mean length of stay was 2.38 (range 1 to 6) postoperative days, median two postoperative days. Serious complications involving suspected drain bile leakage and postoperative hemorrhage occurred in two (0.59%) patients, both in the first 24 h following surgery. One patient required emergency laparotomy on the first postoperative day. Readmission rate was 1.2%. The postoperative minor complication rate was 42 of 337 (12.46%); these included wound infections, urinary tract infections, symptoms included in postcholecystectomy syndrome, etc. The onset of these complications was mostly after postoperative day 3. The data obtained suggest that discharge on the first postoperative day after elective uncomplicated laparoscopic cholecystectomy should be considered safe and can be practiced in our hospital.
Gallstone ileus is an uncommon cause of small bowel obstruction, accounting for only 1% to 4% of all intestinal obstructions. In the group of patients over 65 years of age, gallstones cause about 25% ...of all non‐strangulated obstructions of the small bowel. Gallstone ileus is burdened with high mortality rate, ranging from 12% to 18%, and most patients are of advanced age, with many other concomitant diseases that may increase the operative risk. The purpose of this study was to compare the two investigated surgical procedures: treatment of intestinal obstruction alone or combined with urgent cholecystectomy and fistula repair. Analysis of 30 patients undergoing operation for gallstone ileus at the Clinical Hospital “Sestre milosrdnice” between 1985 and 2001 is presented. Patients were treated either for ileus alone (group 1, 11 patients) or as one‐stage procedure with urgent fistula closure (group 2, 19 patients). Operating time was significantly longer for the one‐stage procedure. Complications occurred in 3 of 11 patients (27.3%) from group 1 and in 11 of 18 patients (61.1%) from group 2 (one tailed, p = 0.043). One patient in group 1 died and two patients in group 2 died. Urgent fistula repair was significantly associated with the occurrence of complications (odds ratio OR 12.1, 95% confidence internal 95% CI 1.2–121.5). Simple enterotomy should be the procedure of choice for patients with gallstone ileus. The one‐stage procedure including urgent fistula repair should be reserved only for highly selected patients with absolute indications.
The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding ...(PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality.
The aim of the study was to assess diagnostic accuracy (sensitivity and specificity)
of Fenyö-Lindberg and Teicher scores for distinguishing patients that need immediate surgical treatment
from the ...others, in a female population from an urban setting. The study prospectively included
130 female patients admitted to the emergency department with abdominal pain indicating acute
appendicitis. The scores and parameters of validity were calculated and compared to definitive diagnosis.
For Fenyö-Lindberg score of -17 or less, 84.5% sensitivity, 55.6% specificity, 87.9% positive predictive
value (PPV) and 48.4% negative predictive value (NPV) were recorded. For cut-off value greater
or equal to -2, there was 59.2% sensitivity, 77.8% specificity, 91% PPV and 33.3% NPV. The Receiver
Operating Characteristic (ROC) curve analysis of Fenyö-Lindberg score showed that the best single
cut-off value for discriminating acute appendicitis in the study population was -15. For Teicher score,
values greater than -3 yielded 89.3% sensitivity and 22.2% specificity, 81.4% PPV and 35.3% NPV. In
conclusion, Fenyö-Lindberg score could be used as an additional tool to exclude appendicitis and
avoid unnecessary appendectomies. Teicher score may help in recognizing patients with appendicitis.
None of the two scores can indicate or decline appendectomy in all cases. Scoring systems may be
useful for pointing to important clinical signs and symptoms in specific subpopulations.
