BACKGROUND Incisional hernia is a frequent complication of midline laparotomy and is associated with high morbidity, decreased quality of life, and high costs. We aimed to compare the large bites suture technique with the small bites technique for fascial closure of midline laparotomy incisions. METHODS We did this prospective, multicentre, double-blind,(More)
In models describing the excitation of muscle by the central nervous system, it is often assumed that excitation during a tetanic contraction can be obtained by the linear summation of responses to individual stimuli, from which the active state of the muscle is calculated. We investigate here the extent to which such a model describes the excitation of(More)
Burst abdomen is a postoperative complication associated with significant morbidity and mortality. The risk factors for burst abdomen are patient- and surgery-related. The management of this complication is a relatively unexplored area within the field of surgery. Relevant surgical outcomes include recurrence, mortality, and incisional hernia. A total(More)
Neck surgery is one of the newest fields of application of minimally invasive surgery. The technique of minimally invasive video-assisted thyroidectomy (MIVAT) developed by Miccoli [1] is the method that has so far become most widespread. Limiting factors of this method include the bothersome 20-mm cervical incision and consequently the specimen size to(More)
Over the past 10 years, several minimally invasive procedures for thyroid surgery have been developed. Because of extensive dissection in the thoracic and neck region, the name “minimal-invasive” is misleading. The aim of this study was to define a new trans-oral access to the cervical spaces especially to the thyroid on the basis of natural orifice(More)
BACKGROUND There is no conclusive evidence which size of suture stitches and suture distance should be used to prevent burst abdomen and incisional hernia. METHODS Thirty-eight porcine abdominal walls were removed immediately after death and divided into 2 groups: A and B (N = 19 each). Two suturing methods using double-loop polydioxanone were tested in(More)
In laparoscopic incisional hernia repair, direct contact between the prosthesis and the abdominal viscera is inevitable, which may lead to an inflammatory reaction resulting in abdominal adhesion formation. This study compared five different synthetic and biologic meshes in terms of adhesion formation, shrinkage, incorporation, and histologic(More)
OBJECTIVE Perioperative blood transfusions may adversely affect survival in patients with colorectal malignancy, although definite proof of a causal relationship has never been reported. BACKGROUND We report the long-term outcomes of a randomized controlled trial performed between 1986 and 1991 to compare the effects of allogeneic blood transfusions and(More)
Die technische Entwicklung der letzten zwei Jahrzehnte bezüglich videoassistierter Chirurgie eröffnete neue Möglichkeiten in der Schilddrüsenchirurgie. Hierbei besteht die Wahl zwischen minimal-invasiven Verfahren mit zervikal sichtbarer Narbe und extrazervikalen Verfahren ohne Narbe am Hals, die jedoch aufgrund der ausgedehnten Präparationsflächen(More)
The use of natural openings for abdominal surgery started at the beginning of the 21th century. A trans-Douglas endoscopic device has been designed to perform most of the intra-abdominal operations in women through the pouch of Douglas. The posterior vaginal vault is limited in size and could be damaged by an oversized instrument. This study investigates(More)
