Pulmonary hernias--defined as protrusions of the lung parenchyma and pleural membranes through a defect in the thoracic wall--are rare. They are usually congenital, spontaneous or traumatic iatrogenic lung herniations are extremely rare and secondary to thoracoscopic procedures or minimally invasive cardiothoracic surgery. There are very few reports of surgical repair of this iatrogenic condition and, to date, no reports of thoracoscopic repair of such defects of the thoracic wall have been reported. We present a case of a young patient with iatrogenic lung herniation in which a thoracoscopic approach was attempted and complete repair successfully accomplished.

In this article we examine our experience over the last 4 years, from 1998 to 2001, in the surgical treatment of colorectal disease using the laparoscopic approach. We treated 200 patients, 54 of whom presented benign disease and 146 malignancies. The operations were performed by a team of surgeons and nurses experienced in advanced laparoscopy. Over this period, the duration of the surgical intervention was gradually reduced by 17%. The conversion rate from laparoscopy to open procedures was also reduced (mean rate 11%). Canalization and the resumption of walking and nutrition were reasonably fast. Postoperative complications occurred in 22% of cases The number of fistulas and anastomotic dehiscences was high (10/200 = 5%), due both to evaluation errors and the choice of surgical material. At present, on applying the criteria of traditional open surgery, this figure is also coming down. Bleeding complications (12/200 = 6%) can also be ascribed to the learning curve (2 bleeds in the trocar site and 2 haematomas in the Pfannenstiel laparotomy site) and are therefore likely to be reduced. Bleeding during the surgical procedures, however, was very low, with a mean value of 69.6 ml. Laparoscopic surgery for colorectal disease is well standardized and we believe there should be no doubts as to its use in benign disease. Its use in oncological surgery, though theoretically correct, needs to be confirmed by the trials currently in progress. The results we have obtained in our experience, after completion of the learning curve, agree with the figures reported in the literature.
