A hematoma is a collection of blood in an extravascular space and is named according to its location. Rectus sheath hematoma (RSH) was first described by Hippocrates and Galen about 25 centuries ago due to abdominal trauma, which is a rare cause of acute abdomen. It is uncommon, which may lead to delayed diagnosis in patients with acute abdomen. This condition arises due to trauma or hypertension in patients with bleeding disorders, using anticoagulants, doing heavy physical exercise, pregnant women, connective tissue diseases, and hematological diseases. The diagnosis can be made by detailed anamnesis, physical examination, ultrasonography, and contrast-enhanced abdominal tomography. For a accurate diagnosis, first of all, the medical history of these patients should be carefully questioned. CT and ultrasonography (USG) are used in the diagnosis of this condition. In many patients, conservative treatment by eliminating the predisposing factor is sufficient. In conclusion, with the increase in use of anticoagulation, the incidence of RSH is expected to increase. Every physician in the surgical field should keep rectus sheath hematoma at the top of the differential diagnosis list in patients presenting with acute abdominal pain and palpable abdominal mass.

Obesity is one of the most important health problems in developed and developing countries. Morbid obesity is defined as having a body mass index (BMI) of more than 40 kg/m2. Obesity does not only predispose to gastroesophageal reflux, but is also an important independent risk factor for the development of hiatal hernia (HH). There are articles advocating about half of obese patients have a hiatal hernia. Hiatal hernia not only exacerbates reflux symptoms, but may also lead to incomplete removal of the gastric fundus during laparoscopic sleeve gastrectomy (LSG). When hiatal hernias are seen preoperatively or intraoperatively for bariatric surgery, surgical correction should ideally be made with mesh reinforcement to prevent further clinical progression.
