Hydatid disease is one of the world's most important health problems. Although several conservative approaches have been used for the management of this condition, surgery remains the ideal choice in most of the cases. Videolaparoscopic approach can safely be applied for the management of liver hydatid cysts if several precautions are undertaken. In this study, we present two liver hydatid cyst cases successfully treated with partial cystectomy and omentoplasty using videolaparoscopic approach.

Meckel's diverticulum, which is a remnant of the omphalomesenteric or vitelline duct, is the most common congenital abnormality of the gastrointestinal system. Urachal abnormalities, resulting from anomalous urogenital development, are not observed frequently and case reports are mainly represented in literature. The presence of these two congenital anomalies together is a very rare pathology. Complications arising from a Meckel's diverticulum or urachal remnant may clinically mimic acute appendicitis and other surgical pathologies. We report on a patient who underwent surgery for acute appendicitis when it was discovered that the symptoms were produced by a perforated Meckel's diverticulitis. In the course of the surgery, a urachal remnant was found to coexist with the diverticulum.

Reconstruction of large skin defects of extremities necessitates wide and flat d o n o r sites. The abdominal region, being a potential d o n o r area, is not suitable due to its concave and relaxed structure. Aiming to create a concave and tense surface, pneumoperitoneu m was performed in two selected cases with extensive skin defects of the lower extremities due to burn trauma and successfully obtained split-thickness grafts from this region. A l t h o u g h further studies are needed to evaluate the safety and efficacy o f this technique, we think that p n e u m o p e r i t o n e u m greatly facilitates obtaining a sufficient a m o u n t o f high quality grafts, even with hand dermatomes.Key words: P n e u m o p e r i t o n e u m -Skin defects -Split skin grafts for pneumoperitoneum. Care was taken to separate the donor site from the umbilicus using steri-strips in order to prevent a possible contamination. Following skin preparation with povidone iodine, a Verres needle was introduced through a 1 cm intra-umbilical incision. The intraperitoneal location of the needle was verified by saline test (5 cc of normal saline was injected without resistance and aspiration was performed without any retrieving saline). The needle was then attached to a high volume CO2 insufflator (Storz, Germany) which was adjusted to obtain an intra-abdominal presReconstruction o f extensive skin defects presents difficulty due to the shortage o f the d o n o r site. Surgeons often face this problem in grafting large skin defects of the extremities where they usually have to use abdominal, thoracic, lumbar or scalp skin for reconstruction. It is not always possible to get a flat and tense surface to harvest a split thickness skin graft (SSG) from these regions due to their anatomic structure. Therefore, we applied p n e u m o p e r i t o n e u m to widen and flatten the abdominal surface to obtain a SSG for the reconstruction of wide skin defects o f the two patients' extremities. TechniqueTwo young patients, 32 and 37 years old, who did not have any medical illnesses or previous abdominal operations, were taken into this trial after their written informed consent. Under general anesthesia, the patients were placed in the Trendelenburg position Fig. 1. By performing pneumoperitoneum, subcostal and lumbar folds are flattened and become tense
