Acute appendicitis in complete situs inversus.
An acute appendicitis was diagnosed in a 29-year-old patient with situs in inversus totalis. Appendectomy was carried out. The incidence, etiology and the diagnosis of complete situs inversus as well as the diagnosis and pitfalls of acute appendicitis in this rare congenital abnormally are described.

Diverticulitis of the ascending colon.
On the basis of three case reports some aspects of diverticulitis of the caecum and ascending colon are discussed. The surgical treatment of congenital diverticula (mostly situated in the caecum) with inflammation should be as conservative as possible to minimize the risk of postoperative complications. Our two patients I and 2 with diverticulitis of the caecum were both treated by ileocaecal resection; possibly in case I diverticulectomy alone would have been sufficient. Patient 3 was treated by right hemicolectomy for a condition residual to (peri)diverticulitis of the ascending colon. In all three cases the postoperative course was uneventful.

Complications of hemiarthroplasty.
The objective of this study was to evaluate the complications of hemiarthroplasty for displaced intracapsular femoral neck fractures. The case histories of 543 consecutive patients with displaced intracapsular femoral neck fractures treated by hemiarthroplasty between 1979 and 1988 were studied. Early mortality was 7.0%. Peroperative complications were seen 23 times (4.2%). Wound complications were seen in 94 patients (17.3%). Ten patients (1.8%) developed a deep infection. Reoperations had to be performed in 19 patients (3.5%). Hemiarthroplasty is major surgery and should not be performed on patients with a limited life expectancy and poor mobility. The main goal of treatment for these patients is to provide the patient with an efficient form of analgesia which can be achieved by simpler techniques of stabilisation of the fracture.
