Describes an unusual complication of the use of laparoscopic trocars under computed tomographic guidance for percutaneous extraction of a foreign body from an infected liver cyst. Retention of the tip of the drain in the cyst after removal; Probability of the recurrence of the cyst; Extraction of the foreign body from the liver cyst under local anesthesia.

Presents a letter to the editor about serum gastrin levels in gallstone patients before and after cholecystectomy.

Objective: This article analyzes radiopaque properties of meshes currently used in hernia surgery. A search was conducted using PubMed and a combination of the terms "hernia repair," "mesh," "laparoscopy," "CT," "MRI," "radiopaque," and "high-resolution techniques.", Conclusion: The visibility of meshes varies from not visible at all (e.g., Ultrapro), to hardly discernible (Prolene), to readily seen (Composix), and finally to the always visible (Dualmesh). Radiopaque properties of meshes have been insufficiently recognized by both the manufacturers and clinicians.

Aim: To give an overview of all negative outcomes of laparoscopic ventral hernia repair., Design: Retrospective cohort study, Methods: Data from all consecutive patients who underwent laparoscopic ventral or incisional hernia repair from January 2000 - May 2010 were summarized in a database. All operative and postoperative complications requiring invasive surgical or radiological intervention were analysed., Results: A total of 803 patients underwent laparoscopy for hernia repair. Conversion to an open operation (n=24; 3%) was needed in 15 cases due to severe adhesions and in 9 due to enterotomy. Laparoscopic repair was completed in 779 patients (97%). Mean follow-up was 35.6 months (SD: 20.3). There were 17 recurrences (2.2%). Other adverse events were: enterotomies (n = 14; 1.8%: 9 recognized intraoperatively and 5 presented postoperatively); postoperative death due to myocardial infarction (n = 1); death due to mesenteric ischemia (n = 1); intra-abdominal bleeding (n = 3); postoperative ileus (n = 2); ileus long after laparoscopy (n = 2); chronic pain (n = 12; 1.6%); trocar-site hernia (n = 7); late mesh infection (n = 5); symptomatic mesh bulging (n = 4); chronic seroma (n = 1)., Conclusion: Laparoscopic correction is an effective method of treating hernias of the abdominal wall and recurrence is low. A total of 8.9% of patients had complications requiring re-intervention. Of these only a quarter were recurrences. On its own, the percentage of recurrences is therefore an inadequate indicator of the outcomes of this operation.
