SUCCESSFUL TREATMENT OF SEVERE PURULENT PERITONITIS WITH INTRAABDOMINAL HYPERTENSION COMPLICATIONS (CLINICAL CASE)

The widely used traditional method of surgical treatment of patients with widespread purulent peritonitis failed to establish itself as universal and has a large number of disadvantages, which prompts the use of new methods of managing patients in the postoperative period in surgical practice. The case described in the work illustrates the possibilities of a successful integrated approach in the treatment of diffuse purulent peritonitis against the background of Abdominal Compartment Syndrome, which includes the «Open abdomen» and «VAC-therapy» techniques, the use of which leads to a persistent decrease in both IАP and relief of the phenomena of purulent inflammation in the abdominal cavity. Conclusions. The use of VAC-therapy in combination with the «Open abdomen» technique leads to a persistent decrease in both ICP and relief of the phenomena of purulent inflammation in the abdominal cavity.

Accessory liver lobe torsion presenting after blunt abdominal trauma

Torsion of an Accessory Liver Lobe (ALL) is a rare cause of acute abdominal pain. The presence of ALL is associated with congenital abdominal wall abnormalities, such as omphalocele or umbilical hernia, and occurs secondary to abnormal liver morphogenesis and intraabdominal hypertension causing liver hypertrophy. Torsion may be triggered by blunt abdominal trauma. We report the case of a 29-year-old male who developed torsion of an ALL arising from hepatic segment 3 after falling. The patient required urgent operative intervention for the treatment of this torsion. This presentation and disease manifestation has been very rarely reported in the literature.

MAIN PRINCIPLES OF ETIOPATHOGENETIC TREATMENT OF NEWBORNS WITH GASTROSCHISIS

Introduction. The paper focuses on the challenging issue of treatment of newborns with gastroschisis (GS) and a high level of intraabdominal hypertension in case of severe viscero-abdominal disproportion. The aim of the paper is to present the current state of the problem at the regional level based on our own clinical experience in observation and treatment of newborns with GS. Material and methods. The study is based on the analysis of examination and treatment of 29 newbornswith GS. The distribution of boys and girls was nearly the same: 16 (55.17%) boys and 13 (44.83%) girls. The number of premature babies was 23 (79.31%). The complex of diagnostic procedures included clinical laboratory examination, radiologic investigation (using contrast agents when required), ultrasound investigation and Doppler sonography, intraabdominal pressure measurement, histologic study of surgical specimens.Results. Prenatal information on the congenital anterior abdominal wall defect was obtained with the help of prenatal ultrasound. In most cases, fetal GS is diagnosed before 20 weeks of pregnancy. Prenatal ultrasound was performed in 13 (44.83%) pregnant women out of the researched group. Two false test results were obtained.Radiologic investigation of a child with GS is necessary to detect intestinal obstruction, necrosis or bowel perforation. Among patients under our study, two cases of ileal atresia were registered. The analysis of intraabdominal pressure indices in patients with GS showed a high level of intraabdominal hypertension in approximately 70% of cases. It proves that patients with GS have a high level of surgical and anesthetic risk. The main therapy measures include the following steps: appropriate preoperative preparation, anesthetic management, and the choice of appropriate perioperative techniques taking into account the level of intraabdominal hypertension and viscero-abdominal disproportion.Depending on the child's condition, type of GS and level of intraabdominal hypertension, there were twosurgical options:1. Primary radical surgery.2. Staged surgical treatment.Analyzing the results of the study, it may be noted that 8 newborns in total died after the surgery, which is 27.59%(it used to be 56-60% till 2005). The main causes of death were respiratory failure, neonatal sepsis and unfavorable premorbid conditions (very low gestational age, severe comorbidity, multiple congenital malformations).Conclusions. 1. Successful treatment of newborns with GS depends on the early diagnosis of the pathology, which must be prenatal, and elimination of contradictions in treatment tactics. 2. Before suturing the abdominal wall defect in newborns with GS, it is necessary to measure intraabdominal pressure, since intraabdominal hypertension leads to a significant deterioration in the mechanical properties of the lungs, hemodynamic abnormalities,oliguria, intestinal ischemia, decrease in organ perfusion, which must be taken into account when carrying out preoperative preparation and aesthetic management. 3. The level of intraabdominal hypertension in patients with GS,which is high in 68.96% of cases, must be an indication for choosing the method of surgical correction of the defect i.e.the refusal of radical plasty of the abdominal wall and the resort to staged intervention or other surgical techniquesthat involve an increase in the abdominal cavity volume. 4. The reduction in mortality in newborns with GS to 27.59%is possible due to the introduction of etiopathogenetic approaches to early diagnosis, preoperative management, anesthetic management and surgical correction of this pathology into the practice of neonatal surgery.

Computed Tomography Findings in Intraabdominal Hypertension in Patients with Acute Pancreatitis

Purpose Intraabdominal hypertension (IAH) in acute pancreatitis (AP) may reduce tissue perfusion and impair organ function and has been shown to portend poor prognosis. We investigated the computed tomography (CT) findings in patients with AP with IAH. Methods This retrospective study comprised of consecutive patients with AP from June 2016 to June 2018 in whom intraabdominal pressure (IAP) was measured. The patients who underwent a contrast-enhanced CT within 7 days of IAP measurement were included. Using a cutoff of 12 mm Hg for IAP, the patients were divided into IAH and non-IAH groups. Measures of severity and clinical outcome were evaluated. CT parameters were compared between the groups. Results The IAH group comprised of 41 patients, while there were 20 patients in the non-IAH group. The IAH group was characterized by severe disease, increased incidence of organ failure, increased requirement for drainage and surgery, prolonged hospital and intensive care unit stay. The mortality was not significantly different between the two groups. On univariate analysis, the CT features that were found to be significantly different between the two groups were the presence of collection (p = 0.036), the maximum dimension of collection (p = 0.004), volume of collection (p = 0.019), biliary dilatation (p = 0.011), and the presence of moderate-to-severe pleural effusion (p = 0.009). On multivariate analysis, all these parameters except biliary dilatation were found to be statistically significant. Conclusion CT findings in patients with AP may suggest IAH. This can be used as an additional marker for severity of AP.

An Ingestible Electronics for Continuous and Real-Time Intraabdominal Pressure Monitoring

Abdominal compartment syndrome can be treated through decompressive surgery if intraabdominal hypertension (IAH) can be detected in time. Treatment delays due to manual, conventional intravesical pressure (IVP) monitoring using a Foley catheter have been reported. In this work, we present an innovative gastrointestinal intraluminal pressure (GIP) measurement-based method to monitor and improve pressure-guided relief of intraabdominal pressure (IAP). A novel algorithm for detecting IAH in the gastrointestinal tract of a live porcine model is reported. A wireless pressure-sensing capsule (10 × 13 mm) was developed for absolute measurement. The IAP was estimated during artificial pneumoperitoneum. The pressure waveform-based measurements indicated that the wireless pressure sensor could be used to predict IAP. To enhance GIP monitoring for predicting IAH, the proposed continuous ingestible wireless electronics-based pressure waveform measurement device can be used as a complement to existing modalities. The use of the proposed pressure measurement and communication technology can help provide valuable data for digital health platforms.

INTRAABDOMINAL HYPERTENSION SYNDROME: CURRENT STATE OF THE PROBLEM

Syndrome of intra-abdominal hypertension (SIAH) is a dangerous complication that can occur in patients with a surgical profile after surgery in the abdominal cavity. Only in the past 25 years has the SIAH been recognized. According to W. Ertel et al., In one third of patients with peritonitis, pancreatic necrosis, injuries of the abdominal cavity and after extensive surgery, there is an increase in intra-abdominal pressure (IAP), while SIAH develops in 5.5% of such patients. Mortality in SIAH is 42–68%. The reason for the development of so many deaths is the presence of diagnostic, preventive and therapeutic measures, as well as differences in the interpretation of terms. Today, much attention is paid to the study of SIAH, official attempts are being made to standardize and define terms and recommended methods of treatment, but this problem needs further study. The review presents data on the current state of the problem, current trends in the diagnosis, prevention and treatment of patients with IAP and SIAH, their use in practical research.
