- AIMS: To analyse time-trends in survival of patients with colon and rectal cancer in Sweden.PATIENTS AND METHODS: Data including all patients diagnosed with adenocarcinoma of the colon and rectum between 1960 and 1999, from the Swedish Cancer Registry, were analysed. The observed and relative survival rates were calculated according to the Hakulinen cohort method.RESULTS: Five-year relative survival rate for cancer of the colon improved significantly from 39.6% in 1960--1964 to 57.2% in 1995--1999 and for rectal cancer from 36.1 to 57.6%, respectively. Corresponding observed survival improved from 31.2 to 44.3% for colon cancer and from 28.4 to 45.4% for rectal cancer. The largest improvement of survival were seen during the later part of the period observed.CONCLUSION: The survival of patients with colon and rectal cancer in Sweden continues to improve, especially in rectal cancer, which now has a 5-year observed and relative survival rate comparable to that for colon cancer. The survival improvement in rectal cancer is probably a result of the implementation of total mesorectal excision and pre-operative radiotherapy.

- BACKGROUND: The aim of the study was to analyse late gastrointestinal disorders necessitating hospital admission following rectal cancer surgery and to determine their relationship to preoperative radiation therapy. METHODS: Curatively treated patients participating in the Swedish Rectal Cancer Trial during 1987-1990, randomized to preoperative irradiation (454 patients) or surgery alone (454), were matched against the Swedish Hospital Discharge Registry. Hospital records for patients admitted with gastrointestinal diagnoses were reviewed. RESULTS: Irradiated patients had an increased relative risk (RR) of late small bowel obstruction (RR 2.49 (95 per cent confidence interval (c.i.) 1.48 to 4.19)) and abdominal pain (RR 2.09 (95 per cent c.i. 1.03 to 4.24)) compared with patients treated by surgery alone. The risk of late small bowel obstruction requiring surgery was greatly increased (RR 7.42 (95 per cent c.i. 2.23 to 24.66)). Irradiated patients with postoperative anastomotic leakage were at increased risk for late small bowel obstruction (RR 2.99 (95 per cent c.i. 1.07 to 8.31)). The risk of small bowel obstruction was also related to the radiation technique and energy used. CONCLUSION: Small bowel obstruction is more common in patients with rectal cancer treated with preoperative radiation therapy.

- AIMS: The aim of this study was to describe variability in compliance to clinical guidelines in colorectal cancer surgery related to hospital structure.METHODS: All patients registered in the databases of the Regional Oncologic Centre, operated upon electively for colon cancer between the start of the register in 1997 until 2000 (n=1771) and for rectal cancer between the start of the register in 1995 until 2000 (n=1841) were selected for analysis.RESULTS: There was no difference in 5-year survival rate between colon and rectal cancer (mean follow-up 2.6 and 3.0 years, respectively; p=0.22). There was a significant difference in frequency of preoperative liver scan depending on hospital category with an increase in colon cancer from 39 to 46% (p=0.02) and in rectal cancer from 42 to 64% (p<0.001). For colon cancer there was no difference, according to hospital category, in quotient sigmoid and high anterior resection to left-sided resection. Furthermore, high anterior resection was more common at university and general district hospitals (8%) compared with district hospitals (4%) (p=0.01). Sphincter-saving surgery was more common at university hospitals and district general hospitals than at district hospitals (low anterior/abdomino-perineal resection quotients 2.3, 2.4 and 1.6, respectively; p<0.001).CONCLUSIONS: Population-based audit forms an appropriate and valuable basis for quality assurance projects. In addition to describing compliance to guidelines and pointing to process steps that can be improved, such investigations may also indicate changes due to scientific development. Linked to case-costing data, such results may form an important basis for decisions about modifications in health care.

- AIM: To investigate the relation between the type of circular stapler and anastomotic leak in rectal cancer surgery.BACKGROUND: During the past decades results from rectal cancer surgery have improved considerably regarding risk of local recurrence and survival. Two main paradigm changes are considered to be the cause for this: the introduction of total mesorectal excision (TME) and the increasing use of radiotherapy. However, rectal cancer surgery is associated with an unacceptably high frequency of complications of which anastomotic leak is one of the most severe ones. The hypothesis was raised that the choice of stapler influenced the leakage rates.METHODS: A questionnaire was sent to all departments of surgery (n = 66) performing rectal cancer surgery in Sweden to determine the choice of circular stapler when performing anterior resection for rectal cancer. These data were linked to the Swedish Rectal Cancer Registry for the period 1995-99.RESULTS: A total of 3316 patients had an anterior resection. The choice of circular stapling device was determined in 70% of the cases. When stapler A was used, the leakage rate was 11% whereas it was 7% when stapler B was used (P = 0.0039). In the cases where it was impossible to determine which stapler had been used the leakage rate was 8%.CONCLUSION: Quality control is an important part of medicine and the present study suggests that it also must include surgical instruments. A prospective randomised study is needed to confirm the results.

- OBJECTIVE: A diverting loop ileostomy was previously considered mandatory for minimizing the effects of septic complications in pelvic pouch surgery. During the past decade there has been a trend towards omission of the loop ileostomy without obvious signs of increased numbers of pouch complications or impaired long-term function. The aim of the present study was to evaluate the risk of complications associated with the construction and closure of the loop ileostomy itself.PATIENTS AND METHODS: Complications following diverting loop ileostomies in 143 patients subjected to restorative pelvic pouch surgery during the period 1983-97 were studied retrospectively by evaluation of case records.RESULTS: In the period between discharge after pelvic pouch surgery and closure of the loop ileostomy, 20 (14%) patients were hospitalized because of excessive stoma flow and 19 (13%) patients were treated for other surgical complications, of whom 10 (7%) required surgical intervention. In the early postoperative period (within 30 days) after closure of the loop ileostomy, 18 (13%) patients suffered complications necessitating surgery. Another 12 (8%) patients were hospitalized because of intestinal obstruction that could be treated conservatively.CONCLUSION: The proportion of complications associated with diverting loop ileostomies in pelvic pouch surgery was considerable. A randomised controlled multicentre study is ethically defensible and is recommended.

- BACKGROUND: The aim of this study was to elucidate the natural history of appendicitis.METHODS: Data was collected prospectively from consecutive patients admitted to hospital for acute abdominal pain. The degree of appendiceal inflammation in relation to preoperative duration of pain was analysed.RESULTS: The study comprised 253 patients operated on for acute appendicitis that could recall the onset of abdominal pain. There was a longer duration of pre-hospital pain in patients, irrespective of age, with perforated appendicitis compared to patients with phlegmonous or gangrenous appendicitis (p < 0.001). In the multivariate analysis, patient age and preoperative duration of pain were independent risk factors for perforation.CONCLUSION: Patient delay in presentation is the predominant factor determining the incidence of complicated appendicitis, and this delay is not influenced by age or gender.

- BACKGROUND: With introduction of the total mesorectal excision technique and preoperative radiotherapy in rectal cancer surgery, the local recurrence rate has decreased and the overall survival has improved. One drawback, however, is the high anastomotic leakage rate of approximately 10-18%. Male gender and low anastomoses are known risk factors for such leakage. The aim of this study was to identify potentially modifiable risk factors. METHOD: In a case-control study, data from the Swedish Rectal Cancer Registry (1995-2000) were analysed. Cases were all patients with anastomotic leakage after an anterior resection (n = 134). Two controls were randomly selected for each case. The medical records (n = 402) were checked against a study protocol. Due to incorrect recording two cases and 28 controls were excluded from further analyses. RESULTS: In the multivariate analysis significant risk factors were American Society of Anesthesiologists score > 2 [OR = 1.40 (95% CI 1.05-1.83)], preoperative radiotherapy [OR = 1.34 (95% CI 1.06-1.69)], intraoperative adverse events [OR = 1.85 (95% CI 1.32-2.58)], level of anastomosis
