ADVERSE EVENTS AFTER PROSTATECTOMY IN VICTORIAN PUBLIC HOSPITALS

Background : A retrospective analysis of data from the Victorian Inpatient Minimum Database (VIMD) was conducted to analyse trends in prostatectomy rates in Victorian public acute-care hospitals from 1989/90 to 1994/95. The study also sought to identify predictors of adverse events (AE) after prostatectomy, and to compare in-hospital complications between open prostatectomy and transurethral resection of prostate (TURP). Methods : All patients who had undergone any prostatectomy were identified according to the relevant ICD-9-CM procedure codes (60.2–60.4) documented in the VIMD. The main outcome measures, AE, were identified using the ICD-9-CM supplementary classification of external cause of injury (E850–858, E870–876, E878–879, E930–949). The variables used as predictors were year of prostatectomy, type of admission (planned, emergency), location of the hospital (rural, metropolitan), type of procedure (TURP, open), and teaching status of the hospital. Crude and adjusted odds ratios (OR) were based on univariate and multivariate logistic regression. Results : The rates of prostatectomies have significantly increased over the 6-year study period (P for trend < 0.0001). The percentage of AE after prostatectomy increased simultaneously from 6.1 to 12.9% (P < 0.0001). During the same period, the in-hospital mortality rate after prostatectomy decreased from 1.2 to 0.5%, and length of stay decreased from 10.3 to 6.1 days (Kruskal–Wallis P < 0.0001). The significant predictors of outcome were year of prostatectomy (P for trend < 0.0001), emergency admissions (OR = 1.57; P < 0.0001), metropolitan hospitals (OR = 0.81; P= 0.0003), non-teaching hospitals (OR = 0.78; P < 0.0001), and open prostatectomy (OR = 1.52; P= 0.04). More in-hospital complications were associated with open prostatectomy than with TURP. Conclusions : The rise in AE rate after prostatectomy is unlikely to reflect poor quality of care, because in the same period there was a significant decrease in in-hospital mortality after prostatectomy. A more likely explanation is heightened awareness of AE with a lower threshold for reporting such events. Important factors other than variations in quality of care can result in an increase in AE. Hence the reported increase should be interpreted with caution before attempting to conclude that changes in clinical practice could have a direct impact on these rates.     

Treatment strategies for hepatic metastasis from colorectal cancer

Hepatic micrometastases of the parenchyma adjacent to a macroscopic lesion were detected in 17 of 31 resected liver metastases. Fifty-nine micrometastatic lesions were detected in total; 26 lesions were situated in the portal vein (PV), 22 in the central vein (CV), 5 in the bile duct (BD), and 6 in the sinusoid (SS). A histological study confirmed the direct invasion of the macrometastatic cancer cells into the adjacent PV, CV, BD, and SS. According to the tumor doubling time, the mean diameter of the macrometastases in 19 remnant livers was calculated to have been 0.57±0.87 cm at the time of the primary resection. The calculated diameter of 3 of these 19 macrometastases was found to be less than 0.01 cm, the minimum implantable size, indicating that the cancer recurrence in these specimens may have developed from macroscopic metastatic lesions as a satellite, and not from the primary tumor. In 13 patients who received doses of 5250 mg or more of 5 fluorouracil (FU) via the hepatic artery, the cumulative disease-free rate 2 years postoperatively was 100%; this value was 47.6% in 11 patients who received less than 5250 mg of 5 FU via the hepatic artery, and 0% in 39 patients who received no chemotherapy (P<0.005). These results suggest that anatomical hepatic resection for satellite lesions, combined with prophylactic hepatic arterial chemotherapy for micrometastases, decreases the recurrence rate of hepatic metastases in the remnant liver.

Plädoyer für die primäre Resektion mit primärer Anastomose bei der komplizierten Sigmadiverticulitis

Zusammenfassung Von 1973 bis 1986 wurden 107 Patienten mit einer komplizierten Sigmadiverticulitis operiert. Es handelte sich um 47 Frauen und 60 Männer bei einem Durchschnittsalter von 62 Jahren. Von 107 Patienten wiesen 14 eine perforierte Diverticulitis mit diffuser eitriger/kotiger Peritonitis auf, 68 Patienten eine perforierte Diverticulitis mit lokalisierter eitriger Peritonitis/paracolischem Absceß und 25 Patienten eine akute phlegmonöse Diverticulitis ohne Perforation. Zusätzliche pathologische Befunde waren: innere Fisteln (13 Patienten), nekrotisierende Fasciitis (3 Patienten), Stenose mit Ileus (3 Patienten) und synchrone Carcinome (7 Patienten). Die Gesamtletalität der 107 Patienten betrug 9,3% (=10 Patienten), die Morbidität der 97 überlebenden Patienten 34,0% (= 33 Patienten). Die Letalität bei 14 Patienten mit perforierter Diverticulitis und diffuser eitriger/kotiger Peritonitis lag bei 50%, die der 68 Patienten mit perforierter Diverticulitis und lokaler eitriger Peritonitis/ paracolischem Absceß bei 4,4%, die der 25 Patienten mit akuter phlegmonöser Diverticulitis ohne Perforation bei 0%. Von den 10 Patienten verstarben 7 bei Operation ihrer perforierten Diverticulitis mit diffuser eitriger Peritonitis, 1 (5) nach primärer Resektion mit primärer Anastomose, 3 (5) nach Operation nach Hartmann, 3 (4) nach alleiniger Anlage einer Colostomie. Bei Operation der perforierten Diverticulitis mit lokaler Peritonitis verstarben 3 Patienten, 2 (6) nach Operation nach Hartman und 1 (5) nach alleiniger Anlage einer Colostomie. Trotz einer hohen Zunahme der Zahl primärer Resektionen mit primärer Anasto mose im Zeitraum 1980–1986 ergab sich im Vergleich zum 7-Jahresabschnitt 1973–1979 ein Rückgang der Letalität von 35,7% auf 0% bei dieser Operation. Ihre Anwendung ist auch gerechtfertigt bei der perforierten Diverticulitis mit lokaler wie diffus eitriger oder kotiger Peritonitis.

Primary resection with primary anastomosis in complicated diverticulitis of the sigma

Summary Of the 107 patients with complicated diverticulitis operated from 1973–1986 47 were females and 60 males. In 14 of the 107 patients a perforated diverticulitis with diffuse purulent/faecal peritonitis was found, a perforated diverticulitis with localized purulent peritonitis/paracolic abscess in 68 patients and an acute phlegmonous diverticulitis without perforation in 25 patients. Additional pathologic findings were internal fistulae (13 patients), necrotizing fasciitis (3 patients), obstruction (3 patients) and synchronous carcinoma (7 patients). The overall mortality of the 107 patients was 9.3 % (=10 patients) and the morbidity of the 97 survivors 34% (=33 patients). The mortality of the 1.4 patients with perforated diverticulitis and diffuse purulent peritonitis was 50%, of the 68 patients with perforated diverticulitis and localized purulent peritonitis 4.4% and of the 25 patients with acute phlegmonous diverticulitis 0%. Seven of the 10 patients died after operation of the perforated diverticulitis with diffuse purulent peritonitis — 1 (5) after primary resection with primary anastomosis, 3 (5) after Hartmann procedure, 3 (4) after loop colostomy alone. Three patients died after operation of the perforated diverticulitis with localized purulent peritonitis — 2 (6) after Hartmann procedure, 1 (5) after loop colostomy alone. In spite of forcing the primary resection with primary anastomosis in the years from 1980–1986 the mortality decreased for these operations from 35.7% in 1973–1979 to 0% in 1980–1986. The indication of primary resection with primary anas tomosis is justified also for perforated diverticulitis with localized and diffuse peritonitis.

Cyclooxygenase-2 expression in colorectal cancer liver metastases

Cyclooxygenase-2 (COX-2) is up-regulated in 85-90% of primary human colorectal cancers and is a putative target for the chemopreventative activity of non-steroidal anti-inflammatory drugs. However, COX-2 expression by human colorectal cancer liver metastases has been poorly characterized. We studied a consecutive series of 38 patients who underwent liver resection for metastatic disease, for whom long-term (up to 57 months), prospective follow-up data were available. Semi-quantitative immunohistochemistry for COX-2 was performed on 54 metastases from 35 patients, for whom adequate histological material was available. Diffuse cytoplasmic staining for COX-2 protein was detected in cancer cells in 100% of metastases (COX-2 score 1, n=25; score 2, n=29). There was no relationship between metastasis size or differentiation grade and the level of COX-2 protein expression. There was no difference in colorectal cancer-free or overall survival between patients with high (score 2) and low (score 1) COX-2 scores (Kaplan–Meier survival analysis and log rank test, both P=0.97). Multivariate Cox regression analysis identified age, incomplete resection and presence of extra-hepatic disease as independent predictors of disease-free and overall survival following surgery. COX-2 protein was also localized to a subset of stromal fibroblasts and mononuclear cells within metastases as well as hepatocytes from resection specimens. COX-2 protein was expressed by cancer cells in all human colorectal cancer liver metastases which were studied. Investigation of the effect of selective COX-2 inhibition on metastasis growth and metastasis cancer cell proliferation/apoptosis in vivo are warranted.
