Background/Aim: In the variety of congenital abdominal cystic lesions (CACL) of different origin, ovarian cyst is the most common intra-abdominal pathology in female neonates. The prognosis and timing of treatment varies depending on the nature of CACL. This study aimed to assess the results of diagnostics and treatment of CACL. Patients and Methods: A retrospective analysis was performed of 39 cases of CACL, with the spectrum including ovarian, enteric, mesenteric and pancreatic origin. Outcome of minimally invasive surgery, open surgery or conservative approach was analyzed. Results: Twenty-eight neonates underwent surgery, while 11 were treated conservatively. Twenty patients were treated with a laparoscopic technique and eight with laparotomy combined with laparoscopy. Final diagnosis included: Fifteen cases of ovarian pathology (ovarian torsion in 11 cases), 12 treated laparoscopically and three with laparotomy, six enteric duplications (four laparoscopic and two laparotomic), three mesenteric cysts (one laparoscopic and two laparotomic), two pancreatic cysts (both laparoscopic only), two duodenal stenoses, including duodenal septum (both laparotomies with Heineke-Mikulicz plasty). No blood transfusion apart from two cases requiring re-laparotomy and no early complications were observed in any case; no death occurred. Conclusion: With the strategy of management based on ultrasound and laboratory data, a laparoscopically assisted minimal access approach resulted in minimal risk of complications and complete recovery in all patients, leading to exclusion of oncological risk.

Osteochondroma is the most common benign bone tumour in children and usually occurs in the metaphyseal region of the long bones, being responsible for over 40% of all bone tumours and tumour-like lesions. The objective of this paper is the presentation of a series of cases of children with osteochondroma with different localisation and clinical presentation. Variability of localisation resulted in differential approach and prevention of permanent complications. Total surgical en bloc excision of the adjacent osteochondroma is considered as the treatment of choice. Symptoms related to an osteochondroma are usually relieved by the surgery. Major complications and local recurrence are rare. The general surgical indications for benign bone growths are cosmetic defect, exostosis in a location at risk to repetitive trauma, increased risk of the exostoses to fracture, neurological involvement, impairment of the articular range of motion, and suspicion of malignancy.
