RESUMO
PURPOSE: Thiopurines are important as maintenance therapy in Crohn's disease, but there have been concerns whether thiopurines increase the risk for anastomotic complications. The present study was performed to assess whether thiopurines alone, or together with other possible risk factors, are associated with postoperative intra-abdominal septic complications after abdominal surgery for Crohn's disease. METHODS: Prospectively registered data regarding perioperative factors were collected at a single tertiary referral center from 1989 to 2002. Data from 343 consecutive abdominal operations on patients with Crohn's disease were entered into a multivariate analysis to evaluate risk factors for intra-abdominal septic complications. All operations involved either anastomoses, strictureplasties, or both; no operations, however, involved proximal diversion. RESULTS: Intra-abdominal septic complications occurred in 26 of 343 operations (8%). Thiopurine therapy was associated with an increased risk of intra-abdominal septic complications (16% with therapy; 6% without therapy; P = 0.044). Together with established risk factors such as preoperative intra-abdominal sepsis (18% with sepsis; 6% without sepsis; P = 0.024) and colo-colonic anastomosis (16% with such anastomosis; 6% with other types of anastomosis; P = 0.031), thiopurine therapy was associated with intra-abdominal septic complications in 24% if any 2 or all 3 risk factors were present compared with 13% if any 1 factor was present, and only 4% in patients if none of these factors were present (P < 0.0001). CONCLUSIONS: Thiopurine therapy is associated with postoperative intra-abdominal septic complications. The risk for intra-abdominal septic complications was related to the number of identified risk factors. This increased risk should be taken into consideration when planning surgery for Crohn's disease.

This 2007 symposium of the Canadian Association of University Surgeons brought together surgeons from a number of jurisdictions to discuss the challenges and opportunities that reduced physician work hours will bring to the care of the surgical patient. Dr. Brian Taylor, president of the association, underscored the need to find a balance between the benefits of diminished workloads/work hours and the loss of continuity of care. He opined that Canada needs to learn from our European colleagues' experience. Dr. Per-Olof Nyström, professor of surgery, presented the modern Swedish model of surgical care, which had to be developed as a consequence of the European Union's legal restrictions on the amount of time an individual surgeon may work. Sweden employs a team-based shared-care model driven by the individual surgeon's expertise rather than the "village factory" model of the multiskilled, multitasking approach of surgical care more prevalent in Canada. Dr. Chris de Gara, secretary treasurer of the association, presented the evidence base for (and against) work-hour restrictions and how well-designed systems can ensure effective continuity of care. Dr. Stewart Hamilton illustrated how one such system for the delivery of the emergency general surgical services has evolved at the University of Alberta Hospital, which demonstrated its effectiveness in providing quality surgical continuity of care. Dr. Debrah Wirtzfeld underscored the importance of trainee lifestyle and how modern Web-based technologies can ensure reduced errors with the implementation of a "sign-out" system.

BACKGROUND: We aimed to improve the postoperative outcome of high-risk patients (American Society of Anesthesiologists class 3 and 4) recovering from colorectal cancer surgery by using recombinant human G-CSF (filgrastim) as perioperative prophylaxis. METHODS: In a double-blinded, placebo-controlled trial, 80 patients undergoing left-sided colorectal resection were randomized to filgrastim or placebo. Filgrastim (5 mug/kg) or placebo was administered in the afternoon on day -1, 0, and +1 relative to the operation. Primary endpoints were in a hierarchic order: quality of life (QoL) over time (determined at discharge, 2 and 6 months after operation with the European Organization for Research and Treatment of Cancer questionnaire) and the McPeek recovery score, which measures death and duration of stays in the intensive care unit and hospital. Predefined secondary endpoints were global QoL, subdomains of QoL, postoperative recovery, duration of stay, 6-month overall survival, complication rates, and cellular and immunologic parameters. RESULTS: There were no significant differences in both primary endpoints between the treatment groups. A significant improvement (P < .05) was obtained by filgrastim prophylaxis in the QoL subdomain family life /- social functioning,; thus, more patients recovered to their preoperative state (14 vs 4 with placebo) as determined by structured interviews. Duration of hospital stay (14 vs 12 days) and noninfectious complications were decreased from 8% to 3%. CONCLUSIONS: High-risk patients undergoing major operation for colorectal cancer profited from filgrastim prophylaxis with regard to duration of hospital stay, noninfectious complications, social QoL, and subjective recovery from operation. These endpoints, however, were secondary, and the primary endpoints (overall QoL and the McPeek index) did not show comparable benefits. A new confirmatory trial with the successful endpoints of this trial, as well as a cost analysis, will be needed to confirm the results before a general recommendation for the prophylactic use of G-CSF in high-risk cancer patients can be given.

No generally accepted measures exist to describe the quality of surgical care. Measures derived from surgical care processes are relatively easy to improve but are often too local to allow comparison with other surgical departments. The final outcome of an operation is often difficult to record objectively or can only be determined after observation. Improving items of the process is often insufficient to markedly improve outcome because process and outcome are logarithmically related. Therefore, a department's surgical balance sheet remains stable over several years. The introduction of new techniques or new concepts of treatment with sufficient potential for change can improve that balance sheet if effectively implemented. Quality of care implies a rating of the outcome relative to a standard or in comparison with the achievement of other surgical departments. It is argued that postoperative hospital stay is an objective, verifiable, and uniformly recorded outcome measure that reflects the combined achievement of the surgical, organisational, and social processes for each patient. Laparoscopic cholecystectomy, a new technique, tension-free inguinal hernia repair, and fast-track surgery, a new concept, all had the potential to shorten the hospital stay. The mode of change seems to be diminished surgical and anaesthetic trauma and therefore fewer complications. The ultimate quality achievement is to be able to operate without causing physiological derangement of the patient, which should eventually allow day-surgery for most elective procedures.

PURPOSE: This study was designed to demonstrate the usefulness of a method of regional anesthesia for circular stapler anopexy for prolapsing hemorrhoids. METHODS: Thirty-three patients consented to stapled anopexy under perianal local anesthesia. Eighteen patients with stapled anopexy under general anesthesia were controls. The perianal block was applied with 40 ml of ropivacaine, 4.75 mg/ml, injected immediately peripheral to the external sphincter. A submucosal block with 15 ml of ropivacaine, 2 mg/ml, was added after applying the pursestring suture. Postoperative pain was rated by the patient for 14 days by using a ten-point visual analogue scale. Patients also submitted a preoperative and postoperative (3-6 months) symptom questionnaire to rate anal symptoms. RESULTS: No operation was converted to general anesthesia. Operation time was similar in both groups. All patients in the local anesthesia group were pain free at discharge. The sums of pain scores during 14 days for daily average pain and peak pain were similar in both groups (average pain 23 (local anesthesia) vs. 35 (general anesthesia); peak pain 39 (local anesthesia) vs. 50 (general anesthesia); P>0.05). The preoperative symptom scores were 7.8 (local anesthesia) vs. 8.9 (general anesthesia) points, and the follow-up scores were 2.2 (local anesthesia) and 2.7 (general anesthesia), a significant improvement (P=0.001) in both groups but not different between groups. CONCLUSIONS: A perianal local block is easy to apply and has a high degree of acceptance among patients. The operation time, postoperative pain, and success rates of the operation equaled those of stapled anopexy performed under general anesthesia. The advantages are quicker turnover between cases and simpler management of pain-free postoperative patients in day surgery.

PURPOSE: The aim of this study was to compare surgical outcome, after low anterior resection for rectal cancer with colonic J-pouch, at two departments with a different policy regarding the use of a routine diverting stoma. METHODS: A total of 161 consecutive patients with invasive rectal carcinomas operated on between 1990 and 1997 with a total mesorectal excision and a colonic J-pouch were included in the study. Eighty patients were operated on in a surgical unit using routine defunctioning stomas (96 percent), whereas 81 were operated on in a department in which diversion was rarely used (5 percent). Recorded data with respect to surgical outcome were analyzed and compared. RESULTS: There was no difference between the two centers in postoperative mortality in connection with the primary resection and subsequent stoma reversal (3.7 vs. 3.8 percent). No significant difference could be found in the number of patients with pelvic sepsis (anastomotic leaks; 9 vs.12 percent). Surgical outcome in patients with pelvic sepsis was also similar. The frequency of reoperations associated with the anterior resection and subsequent stoma reversal was identical (14 percent). The total hospital stay (primary operation and stoma reversal) was significantly longer with than without a routine stoma (17 (range, 2-59) vs. 12 (range, 5-55) days, respectively; P < 0.001). CONCLUSION: This study suggests that the routine use of diversion does not protect the patient from anastomotic complications or pelvic sepsis and its use requires a second admission for closure.
