The risk for intraabdominal abscess (IAA) after laparoscopic appendectomy (LA) is still a matter of debate. The aim of the present study was to evaluate postoperative complications after open (OA) and laparoscopic appendectomy, in particular in perforated appendicitis (PA).In the period 1999-2002, 331 appendectomies were performed for histological proven appendicitis, 144 by the open and 187 by the laparoscopic technique. Parameters were conversion rate, perforation, wound infection, and IAA.Conversion to OA was done in 20 cases (10.7%). Perforated appendicitis led more frequently to conversion than simple appendicitis (23.5 vs 7.8%; p = 0.007). Perforated appendicitis was equally seen in the open and laparoscopic technique (15 vs 18%). Wound infections after OA, converted and LA for acute appendicitis were 3 of 144 (2.1%), 1 of 20 (5.0%) and 1 of 167 (0.6%), respectively (NS). IAA formation did not differ among the three procedures (3.5 vs 0 vs 3.6%). In PA the rate of IAA formation was increased. However, the risk was not influenced by the technique: Two patients after the OA, none after a converted procedure, and two patients after LA formed an abscess (9.5 vs 0 vs 7.7% [NS]).LA does not lead to more intraabdominal abscesses than the open technique; even for perforated appendicitis the laparoscopic technique can be used safely.

Case report about a minimally invasive technique for removal of a femoral antegrade nail (FAN). Femoral nails are introduced by minimally invasive techniques, but are often removed with more invasive surgery. Four cases of young patients are described in whom the femoral nail was removed after consolidation by a minimally invasive extraction technique at the trochanteric site. By using a threaded wire for locating the proximal entrance of the femoral nail followed by reaming over the wire, the entrance of the nail in the trochanteric region is freed. Then the extraction bolt can be placed over the wire and the nail can be extracted through the same incision as it was inserted in, without enlarging the incision. This case report discusses a technique for minimally invasive femoral nail extraction, not the necessity of removing nails. Leaving out the endcap at the initial operation is the only preoperative condition, since the endcap blocks the entrance of the nail. This operation is done with fluoroscopic guidance. The difficult part is the reaming. The reamer must not be damaged when approaching the nail entrance. This minimally invasive femoral nail extraction technique is applicable for various types of femoral nails. Minimally invasive extraction of femoral nails is possible and needs more attention. The level of evidence is a level IV case series.

BACKGROUND: A retrospective study was done to determine whether laparoscopic adhesiolysis benefits patients with chronic abdominal pain. Factors that influence complications and feasibility of laparoscopic adhesiolysis were evaluated. METHODS: 174 consecutive operations in 157 patients were retrospectively analyzed for factors which might influence the complication rate and the feasibility of laparoscopic adhesiolysis. RESULTS: In 128 out of 174 procedures a complete adhesiolysis was performed. We had to accept an incomplete adhesiolysis in 39 other patients and in 7 patients a primary conversion was needed. We noticed 16 major complications. Two patients died. Relief of pain was recorded in 80% of patients after short follow-up. The number of previous abdominal operations and patient age significantly affected the outcome of surgery. CONCLUSION: Laparoscopic adhesiolysis in patients with chronic abdominal pain seems to be a feasible and effective operation with considerable risk.
