The risks and benefits of surgery for colorectal cancer in old patients have not been unequivocally defined. The present investigation was carried out in 309 hospitals as a prospective multicenter study. In the period between 1 January 2000 and 31 December 2001, a total of 19,080 patients were recruited for the study; 16,142 (84.6%) patients were younger than 80 years (<80) and 2932 (15.4%) were 80 years and older (> or =80). Significant differences between the age groups were observed for general postoperative complications (22.3% for <80 years; 33.9% for > or =80). Specific postoperative complications were identical in both groups. Overall, significantly elevated morbidity and mortality rates were found with increasing age (morbidity: 33.9% vs. 43.5%; mortality: 2.6% vs. 8.0%). The distribution of tumor stages revealed a significantly higher percentage of locally advanced tumors in the older age group (stage II: 28.0% vs. 34.4%). In contrast, no increase in metastasizing tumors was found in the older age group (stage IV: 17.4% vs. 14.1%). Logistic regression showed that, in concert with a number of other parameters, age is a significant influencing factor on postoperative morbidity and mortality. The increase in postoperative morbidity and mortality rates associated with aging is a result of the increase in general postoperative complications, in particular, pneumonia and cardiovascular complications. Age as such does not represent a contraindication for surgical treatment. The short-term outcome and quality of life are of overriding importance for the geriatric patient.
Acute appendicitis during pregnancy is a rare event, and large numbers of cases reported in the literature stem entirely from data stored in national registers. Between 1974 and 2000 relevant perioperative data on the treatment of appendicitis were collected consecutively and analyzed retrospectively. Surgical and obstetric data relating to the medical history, the clinical, intraoperative, and histologic findings, and the course of the pregnancy were recorded. Altogether, 9793 appendectomies were performed, 94 of which were in pregnant women (24.5% during the first trimester, 51% during the second trimester, and 24.5% during the third trimester). This represents 0.2% of the 46,960 deliveries during the period under observation. Fifty percent of the case histories during the second trimester were atypical. The overall perforation rate was 14.9%; it was 8.7%, 12.5%, and 26.1% during the three trimesters, respectively. Maternal mortality was 0%; the combined miscarriage/abortion rate was 8.5% (n = 8); and infant mortality was 3.2% (n = 3). The postoperative spontaneous abortion rate was 13.0% and the additional therapeutic/requested abortion rate 21.7% during the first trimester. In view of the elevated postoperative abortion rate and the facility of the clinical diagnosis during the first trimester, the indication for invasive diagnostic measures and surgery requires careful consideration. During the second and third trimesters the difficulty of establishing a clinical diagnosis makes it necessary to undertake exploratory surgery early.
Conflicting reports are found in the literature concerning whether to remove an incidentally discovered Meckel's diverticulum (MD). Between 1.1.1974 and 31.12.2000, at a single center, the perioperative data associated with appendectomy (AE) were recorded consecutively and analyzed retrospectively. All patients in whom an MD was discovered during an AE were included in the study. The clinical presentation, postoperative course, and follow-up in all MDs left in place were analyzed. During the course of 7927 AE, 233 MD (2.9%) were detected. Of these 80.7% (n = 188) were removed and 19.3% (n = 45) were left untouched. In 9% (n = 21) of all detected diverticula pathological changes were found. Ectopic tissue was seen in 12.2% (n = 23) of the MDs removed. The postoperative complication rates did not differ significantly between patients in whom the MD was removed (9.5%; n = 18) and those in whom it was not (17.7%; n = 8); in the latter group the appendicitis was of the more acute type (gangrenous or perforated) (24.4% vs. 4.3%). In 18 patients (40.0%) with non-removed MDs, a follow-up period of 14.1 5.8 years was achieved. Complications associated with a non-removed MD were not observed. If during the course of an AE a MD is detected, the present data, as well as those in the literature, suggest that an individualized approach should be taken. Meckel's diverticulum with obvious pathology should always be removed. In cases of gangrenous or perforated appendicitis, an incidentally discovered MD should be left in place, whereas in an only mildly inflamed appendix it should be removed.
