Computed Tomography Findings Predicting the Need for Surgery in Cases of Small Bowel Obstruction: Emphasis on Duodenal Distension.

OBJECTIVE: The aim of the study is to retrospectively evaluate the utility of computed tomography (CT) findings, especially newly defined duodenal distension, for predicting the need to operate on small bowel obstruction (SBO) cases. METHODS: During a 51-month period, 228 patients (100 women and 128 men; mean age, 55 years) were included in this study, among 438 patients who were hospitalized with a prediagnosis of SBO. The final study population was then divided into 2 groups: a surgery group (n = 76) and a conservative group (n = 152). The CT findings of the SBO patients whose treatment decisions and outcomes were unknown were examined by 2 gastrointestinal radiologists with consensus. Statistical analyses were conducted using univariate and binary logistic regression analyses. RESULTS: According to the univariate analysis, the degree of obstruction (P = 0.001), small bowel diameter (P = 0.014), and presence of mesenteric fluid (P < 0.001), intraperitoneal free fluid (P = 0.04), intra-abdominal free gas (P < 0.001), and duodenal distension (P < 0.001) showed statistically significant differences between the surgery and conservative groups. However, there were no statistically significant group differences regarding the presence of a transition point, small bowel feces or mesenteric congestion. According to the binary logistic regression analysis, the degree of obstruction (P = 0.012), presence of mesenteric fluid (P = 0.008), intra-abdominal free gas (P = 0.019), and duodenal distension (P < 0.001) were significant predictors of the need for surgery in SBO cases. CONCLUSIONS: Duodenal distension as a CT finding predicted the need for surgery in SBO cases.

The Potential Prognostic Significance of the Laboratory Risk Indicator for the Necrotizing Fasciitis (LRINEC) Score in Necrotizing Fasciitis.

Background: We discuss the role of Laboratory Risk Indicator for the Necrotizing Fasciitis (LRINEC) on the prognosis of this disease. Necrotizing Fasciitis (NF) is characterised by rapid spreading of infection and necrosis of the soft tissues and fascia. Methods: Thirty patients (17 male, 13 female, mean age 57.5 years) were treated between 2011- 2016 (in our center); they were analysed retrospectively regarding age, sex, isolated microbiological agents, modalities of treatment and mortality rate. Results: The majority of the infections were detected in the perineum (14 patients). Other sites of infection were: the presacral region (3 patients), as well as abdominal region after elective (10 patients) and emergency surgery (2 patients), respectively. 53.3% of patients had at least one predisposing comorbid factor such as diabetes mellitus, hypertension, cardiomyopathy and congestive heart failure. The tissue cultures were positive in 12 patients. Mean LRINEC score on admission was 8.5 +-2.85. There was a strong correlation between LRINEC score and patient age (p=0.018, R=0.43). LRINEC score was affected by neither gender nor the presence of any comorbidities. The patients were classified according to Wang and Wong staging system, as follows: one patient in stage 1, 15 patients in stage 2 and 14 patients in stage 3. Patients with higher Wang and Wong stages had significantly higher LRINEC scores. The mortality rate was 16.7%. The mean LRINEC score of deceased patients compared to patients who were successfully treated was 9.2Â+-2.2 and 8.36Â+-2.9. Conclusion: Even though LRINEC score and Wang and Wong stage were significatly related with ICU stay, their direct effect on mortality wasn't significant in our study.
