Small Bowel Obstruction (SBO) is a clinical condition characterized by the interruption of normal intestinal flow. The most common causes include intraperitoneal adhesions with approximately 60-70% of cases. Other causes include neoplasm, hernias, obstructive foreign bodies or gallstones, inflammatory disease or iatrogenic causes. Some symptoms are abdominal pain, distention, vomiting, constipation progressing to obstipation some signs of sepsis. Principal diagnostic tests include leukocytosis, elevated lactic acid, metabolic acidosis and some characterized findings in abdominal CT or x-ray. Internal abdominal hernias are secondary to the protrusion of an abdominal organ through a mesenteric or peritoneal defect, congenital or acquired. They occur with an incidence of less than 1%, but constitute 5.8% of all SBO and, due to their late diagnosis, they usually have a mortality rate exceeding 50%. The most common internal hernias are paraduodenal, which account for 50% to 55% of cases; other less common hernias include hernias through the foramen of Winslow (6% to 10%), transmesenteric (8% to 10%), pericecal (10% to 15%), intersigmoid (4% to 8%), paravesical, supravesical and pelvic (<4%). In paravesical hernias, the defect is located between the median and medial umbilical ligaments. There are four subtypes based on the course of the herniated organs: anterior, posterior, right, or left lateral. The most frequent clinical manifestation is bowel obstruction. The radiological findings of the internal paravesical hernias include a cluster of bowel loops and mesenteric fat adjacent to the bladder with proximal dilatation, deformity of the bladder walls adjacent to the hernia and congestive mesenteric vessels. According to our case, a “closed loop” adjacent to the bladder also could be found. The second case is about a transvaginal intestinal evisceration causing an incarceration of small bowel and intestinal obstruction. The dehiscence occurs in less than 1% of hysterectomies and of these 35-60% result in evisceration. SBO is a frequent surgical event but some etiologies are rare for that reason if the patient does not present typical signs or symptoms we have to think of the rare causes and some radiology studies such as abdominal CT are necessary.

Loss of domain (LOD) is a critical concept in hernia surgery, referring to the displacement of abdominal contents between a hernia sac and the remaining abdominopelvic cavity. Large ventral hernias, often resulting from factors like intra-abdominal sepsis and prior laparotomies, pose significant challenges due to their size and complexity. As the hernia enlarges over time, anatomical and physiological changes occur, including retraction and fibrosis of abdominal muscles, leading to decreased intra-abdominal pressure and respiratory dysfunction. The consequences of LOD extend beyond anatomical changes. Portal venous stasis can lead to bowel edema and ischemia, exacerbating complications such as diarrhea and abdominal pain. Malalignment of muscles and reduced intra-abdominal pressure can also result in chronic back pain. These effects were first elucidated by Rives in 1973, termed "eventration disease." Addressing large ventral hernias requires a multidisciplinary approach involving specialists such as pulmonologists, radiologists, nutritionists, anesthesiologists, and cardiologists, alongside surgeons. Preoperative preparation, including CT abdominopelvic studies and interventions like PPP and botox injections, can optimize outcomes and mitigate complications. Controlling abdominal pressure during preparation and surgery is crucial to prevent complications like abdominal compartment syndrome and respiratory distress. Collaborative planning over 3-4 weeks before surgery is essential to ensure comprehensive evaluation and preparation, minimizing risks during the procedure and enhancing postoperative recovery. By integrating various specialties and employing proactive measures, such as PPP and controlled abdominal pressure, the surgical team can optimize outcomes and minimize complications associated with large ventral hernia repair.

Non-alcoholic fatty liver disease or NAFLD talk about the presence of hepatic steatosis when no other causes like heavy alcohol consumption are present. Related to obesity or metabolic syndrome is the fatty infiltration of the liver. Usually, we talk of two principals forms Non-Alcoholic Fatty Liver Disease (NALFD) or Non-Alcoholic Steatohepatitis (NASH) is hepatic inflammation is associated with the hepatic steatosis. NASH has to be with hepatic inflammation a non-reversible stage. Incidence documented by US was 12%. Subjects free of NALFD followed by 4,5 years the reported incidence was 29.7-1.000. In England, was 29 – 100.000, Israel 28 per 1.000. A global metanalyses shown a prevalence around 25,24% in South America 30,45% or Middle East 31,79% contrary to Africa with 13,48%. Risk factor associated are central obesity, DM, dyslipidemia, metabolic syndrome, male sex, Hispanics, OSA, age over 40 and polycystic ovary syndrome. Usually diagnosed by ultrasound but we can also study with CT or MRI. Sometimes with increase liver enzymes but normal values do not exclude the presence of NALFD. The gold standard is liver biopsy and with this method we can differentiate the stage between NALFD or NASH.

The main cause of death in traumas is hypovolemic shock. Regardless computed tomography is the gold standard in hemodynamically unstable patients ultrasound can be a rapid, reproducible, portable, and noninvasive method such as ultrasound emerged, directed for detecting hemopericardium, hemoperitoneum, and hemopneumothorax, in a "point of care" modality, known as the focused assessment with sonography for trauma (FAST) protocol. Also, is performed in stable patients as a first option in trauma algorism. Is a simple approach performed in 2-3min evaluating four regions to be examined in the traditional FAST protocol: pericardium (to detect cardiac tamponade), right upper abdominal quadrant, left upper abdominal quadrant, and pelvis (to detect hemoperitoneum). The called extended FAST (e-FAST) protocol also searches the pleural spaces for hemothorax and pneumothorax. Also, in a specific exploration in stable patients, it can be useful to explore visceral damage in solid organs such as the liver, spleen or kidney. FAST/e-FAST protocol is designed to provide a simple "yes or no" answer regarding the presence of bleeding. We don´t use the FAST protocol to estimate the quantity of free liquid in the abdominal cavity but is used to determine the presence or not. CT should be considered for hemodynamically stable patients.
