Introduction: Diffuse peritonitis is a serious disease. It is often addressed within urgent management of an unstable patient in shock. The therapy consists of treatment of the source of peritonitis, decontamination of the abdominal cavity, stabilization of the patient and comprehensive resuscitation care in an intensive care unit. A number of scoring systems to determine patient prognosis are available, but most of them require complex input data, making their practical application a substantial problem. Objective: Our aim was to assess simple scoring systems within a cohort, evaluate the level of mortality, morbidity, and duration of hospital stay, followed by a comparison of the acquired data with the literature and determination of an easily implementable scoring system for use in clinical practice. Material and Methods: We evaluated a group of patients with diffuse peritonitis who underwent surgery in the 2015–2019 period. Medical history, surgical findings, and paraclinical examinations were used as the input for four scoring systems commonly used in practice—MPI, qSOFA, ECOG, and ASA. We compared the results between the systems and with the literature. Results: Our cohort included 274 patients diagnosed with diffuse peritonitis. Mortality was 22.6%, morbidity 73.4%, with a 25.2 day average duration of hospital stay. Mortality and morbidity increased with rising MPI and qSOFA, well-established scoring systems, but also with rising ASA and ECOG, similarly to MPI and qSOFA. Conclusions: The utilized scoring systems correlated well with the severity of the condition and with predicted mortality and morbidity as reported in the literature. Simple scoring systems primarily used in other indications (i.e., ASA and ECOG) have a similar predictive value in our cohort as commonly used systems (MPI, qSOFA). We recommend them in routine clinical practice due to their simplicity.

The frequent occurrence of E. coli positive for cyclomodulins such as colibactin (CLB), the cytotoxic necrotizing factor (CNF), and the cytolethal distending factor (CDT) in colorectal cancer (CRC) patients published so far provides the opportunity to use them as CRC screening markers. We examined the practicability and performance of a low-cost detection approach that relied on culture followed by simplified DNA extraction and PCR in E. coli isolates recovered from 130 CRC patients and 111 controls. Our results showed a statistically significant association between CRC and the presence of colibactin genes clbB and clbN, the cnf gene, and newly, the hemolytic phenotype of E. coli isolates. We also observed a significant increase in the mean number of morphologically distinct E. coli isolates per patient in the CRC cohort compared to controls, indicating that the cyclomodulin-producing E. coli strains may represent potentially preventable harmful newcomers in CRC patients. A colibactin gene assay showed the highest detection rate (45.4%), and males would benefit from the screening more than females. However, because of the high number of false positives, practical use of this marker must be explored. In our opinion, it may serve as an auxiliary marker to increase the specificity and/or sensitivity of the well-established fecal immunochemical test (FIT) in CRC screening.

Acute appendicitis is one of the most common surgical diagnoses in clinical practice. In case of uncomplicated course, diagnosis and treatment do not cause significant difficulties. On the other hand, unrecognized or complicated appendicitis can rarely bring unusual complications that threaten the patient with delayed treatment rather than the course itself. Portal vein thrombosis, also known as pylephlebitis, with an incidence of 1/1000 acute admissions, certainly meets this statement. In this study, we present a successful treatment of advanced acute appendicitis complicating treatment of biliary obstruction. Due to the advanced inflammation with forced intestinal resection in the extent of right-sided hemicolectomy. And then successful conservative treatment of portal vein thrombosis in the surgical facility lasting a total of 6 weeks when the patient was discharged to home care without sequelae. The epidemiology, presentation, diagnosis and strategy of treatments as well as their outcomes were discussed. Portal vein thrombosis after acute appendicitis is rare. In case of unfavorable postoperative course with high inflammatory markers, temperatures, discomfort and abdominal pain, a CT scan is in order, which can easily establish the diagnosis and subsequently target the treatment in the right direction. Treatment of pylephlebitis is conservative and long term. It consists in the application of low molecular weight heparin and targeted antibiotic treatment. The mortality rate is 32%.

Postoperative complications of rectal resections classified as grade III or higher according to Clavien-Dindo system, which also include anastomotic leaks, are usually life-threatening conditions. Delayed diagnosis may account for almost 18% of deaths. Due to nonspecific clinical signs in the early postoperative period, diagnosing these complications may truly be a challenge for clinicians. Nowadays, with the implementation of the ERAS protocol (enhanced recovery after surgery) and efforts concentrated on quickly delivered treatment to patients suffering from the above-mentioned complications, an appropriate marker with high specificity is required. Postoperative levels of C-reactive protein in blood serum seem promising in this aspect. The presented study aimed to determine the cut-off level of serum C-reactive protein as a possible predictive factor for early diagnosis of serious postoperative complications associated with rectal resections. This could also lead clinicians to the diagnosis of anastomotic leak after other possible options are ruled out. This study is a retrospective observational analysis of patients who underwent open resection of rectal cancer during a one-year period. Collected data included risk factors (age, gender, BMI, bowel preparation), record of complications and C Reactive Protein (CRP) serum levels. The study included 162 patients. Uncomplicated postoperative course was observed in 58 patients (35.8%). Complications were present in 104 cases (64.2%), including surgical site infections (16.7%) and anastomotic leak (9.9%). The mortality rate was 2.5%. Serum CRP threshold predicting relevant complications reached a sensitivity of 83.3% and specificity of 82.7% on POD 4, with a 175.4 mg/L cut-off value, burdened with a 95.7% negative predictive value. Postoperative serum C-reactive protein may be used as a good predictor of infectious complications, including anastomotic leaks. Measuring CRP levels in the early postoperative period may facilitate identification oflow-risk patients ensure early and safe discharges from hospital after rectal resections.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is one of the most efficient bariatric interventions in morbidly obese patients. The most severe risk of this procedure seems to be the staple line leak, and the management of this complication can be very arduous. Aim : To share our...

Purpose: Healing of colorectal anastomosis is burdened with a number of risk factors and the development of leak carries with it higher morbidity and mortality associated not only with worse quality of life but also worse oncological outcomes. The purpose of the study was an evaluation of the effect of reinforcement suture in the healing of stapler rectal anastomosis and risk factors for anastomotic leakage in mid, upper rectal and sigmoid tumors.Methods: A total of 357 patients who underwent curative resection for rectal or sigmoid tumor over 5 years were analyzed. Risk factors, baseline demographic and clinical data, and presence of leak were recorded. All statistical analyses were carried out at a significance level of P<0.05.Results: One hundred fifty-one patients met the inclusion criteria for the study. The overall incidence of leak was 2.8% in the group with reinforcement suture and 6.3% in the group without reinforcement suture. Because of the low incidence of leak the results were not statistically significant. Further results also show that none of the monitored parameters (age, weight, body mass index, tumor distance, preoperative radiotherapy, tumor stage, type of surgery) were significant predictors of anastomotic leakage.Conclusion: Although the reinforcement suture is a safe and simple option for anastomosis protection after rectal or sigmoid resections, its statistical significance was not demonstrated in our study.
