[Invagination in an adult as a rare cause of acute abdomen - 2 case reports]. / Invaginace u dospelého jako vzácná prícina náhlé príhody brisní - 2 kazuistiky.

The authors present two cases of intestinal invagination in adult patients. The first case is an 84-year-old polymorbid female patient indicated for acute surgical revision due to ileus with a finding of invagination in the sigmoid area, with no evidence of an organic cause. The second case, an 80-year-old polymorbid female patient, was indicated for acute surgical revision also due to ileus with a finding of invagination on the small intestine and with a proven neuroendocrine tumor. Unlike invagination in childhood where its cause is usually unknown[1,7], intestinal invagination is relatively rare in adults and it is mostly due to an organic cause, most frequently a benign tumor of the small intestine[2]. This study focuses on invagination as a rare cause of acute abdomen in adult patients.Key words: invagination - ileus - idiopathic.

[Abdominal actinomycosis - 3 case reports and literature overview]. / Brisní aktinomykóza - 3 kazuistiky a prehled literatury.

The authors present three cases of abdominal actinomycosis that were initially diagnosed as acute appendicitis, an abscess in the left groin and pelvic tumour, probably of gynaecological origin. Definitive diagnosis of abdominal actinomycosis was established as late as postoperatively. Abdominal actinomycosis is a chronic, infectious disease characterized most frequently by non-specific symptoms such as abdominal pain, fever, vomiting, bowel obstruction, weight loss, sometimes palpable resistance, and leukocytosis [1-9]. Diagnosis may be difficult and needs to be taken into account, especially in patients with risk factors.

[Laparoscopic appendectomy in pregnancy - a case report]. / Laparoskopická apendektomie u tehotných - kazuistika a prehled literatury.

The authors present a case of a 25- year- old pregnant patient diagnosed with acute appendicitis, indicated for laparoscopic appendectomy based on a consultation with gynecologists. No complications occurred during postoperative recovery and the patient was discharged on the fifth postoperative day, vital fetus with normal development. This case review points out a rarely discussed topic of laparoscopic appendectomy in pregnant women as a safe alternative to open surgery. Appendicitis is one of the most common indications for surgery during pregnancy. Appendicitis in pregnancy represents a challenge for a surgeon, both in terms of diagnosis as well as treatment and choice of surgical approach.
