[Laparoscopic gastric banding using a modified gastric band with loops and a microport system. A report on 25 cases].

INTRODUCTION: The laparoscopic application of an adjustable silicone gastric band is an established procedure in the surgical treatment of pathologic adiposity. PATIENTS AND METHODS: Twenty-five patients with morbid obesity underwent the laparoscopic application of a gastric band between November 1998 and June 2000. A modified band (GastroBelt II) was used. RESULTS: Early and late complications were rare in comparison with previous procedures. Complications, which often require surgical intervention, such as slipping of the stomach (8-12%) or pouch dilatation (2-4%), were not observed. The total morbidity rate and mortality rate were both 0%. CONCLUSION: Critical selection of the patients before the operation and appropriate compliance produced an average loss of weight of 7% of the overweight at 6 weeks, 20% at 3 months and 28% at 6 months after the operation. Preconditions for this operation are a coordinated operation team and a clearly defined standardized postoperative care concept.

[Laparoscopic fascia closure with the Carter-Thomason instruments].

An operative technique is described for fasciorrhaphy of large laparoscopic incisions, umbilical hernias or small abdominal wall hernias with laparoscopic monitoring within the scope of minimal invasive surgery. Over a period of 8 months the Carter-Thomason technique was used in 105 operative laparoscopies for occlusion of large laparoscopic incisions and in 6 pre-existing umbilical hernias. In the postoperative period no hernias occurred and no complications were observed.

[Laparoscopic suture and knot techniques].

Laparoscopic suture and knot techniques are not yet considered standard laparoscopic procedures. In conventional surgery, it would be unthinkable that a procedure would be attempted without a good working knowledge of suture and knot techniques. In laparoscopic operations, limited mobility, the lever arm through the instruments and especially the conversion of 2D vision to 3D actions and the lack of a direct tactile sense all have limiting effect. The needle holders available leave room for improvement. The initially protracted operating times become shorter with training and a period of adjustment.

[Technique in laparoscopic cholecystectomy. Experiences and results in 200 interventions].

This study provides the data and experience of 200 laparoscopic cholecystectomies. The stenosis of the bile duct caused by a ligature in one patient and aberration of the bile duct in two patients led to remarkable intraoperative complications. The average operation time as well as postoperative recovery periods emphasize the importance of laparoscopic cholecystectomy as a relevant alternative to the traditional approach.

[Laparoscopic placement of T-drainage in choledocholithiasis].

This case report illustrates the feasibility of bile duct revision and T-tube insertion by laparoscopic approach. The procedure largely employs the traditional action. Laparoscopy demands more skill, particularly regarding the suture of the common bile duct, but does not interfere its realisation.
