A prospective, randomized clinical trial of preoperative bowel preparation for elective colorectal surgery--comparison among oral, systemic, and intraoperative luminal antibacterial preparations.

During a one year and six month period, 137 patients undergoing elective colorectal surgery for carcinoma were randomly allocated to three groups. Patients in group A received oral tobramycin and metronidazole for three days prior to surgery. Patients in groups B and C received systemic antibiotic, a second generation cephem cefmetazole, every 3 hours during surgery. Patients in group C also received a luminal preparation of tobramycin during surgery. All patients received mechanical bowel preparation in the same manner. The incidence of postoperative wound sepsis was 10.9% in group A, 9.8% in group B, and 10.0% in group C. There were no significant differences in postoperative wound sepsis among the three groups. The oral antibiotic regimen induced a greater change in intestinal flora and was associated with more frequent postoperative diarrhea. Although the preoperative bowel preparation taken for patients in group A could not sufficiently reduce the intestinal bacterial count, systemic antibiotic prophylaxis was simple and cost-effective. There was no additional advantage in combining the systemic and luminal antibiotic preparations. Therefore, for elective colorectal surgery, we recommend intravenous infusion of second generation cephem cephmetazole with mechanical bowel preparation.

Sequential compression devices as prophylaxis for venous thromboembolism in high-risk colorectal surgery patients: reconsidering American Society of Colorectal Surgeons parameters.

The American Society of Colorectal Surgeons (ASCRS) recently endorsed low-molecular-weight heparin and low-dose heparin as primary prophylaxis for venous thromboembolism (VTE) in highest-risk patients. Our study evaluates the feasibility of sequential compression device (SCD) use for VTE prophylaxis in these patients. Computerized databases of discharge diagnoses from three hospitals were reviewed. All patients with colorectal cancer or inflammatory bowel disease during a 7-year period were identified. Those who underwent major abdominal surgery and received VTE prophylaxis exclusively with SCDs were selected for the study. Patients diagnosed with postoperative VTE were identified through review of the three databases and of patient records for 90 days after surgery. One thousand two hundred eighty-one patients classified as highest-risk under the published ASCRS parameters underwent major abdominal surgery and received SCDs perioperatively. The incidence of clinically detectable postoperative VTE was 0.78 per cent. There were trends toward lower incidence among patients with malignancy (0.53%) compared with inflammatory bowel disease (1.48%, P = 0.09), and those with abdominal compared to pelvic procedures (0.62% vs. 1.04%, P = 0.41). Prophylaxis for perioperative VTE solely with SCD is a viable option for patients classified as highest-risk under ASCRS parameters.

Single or multiple doses of metronidazole and ampicillin in elective colorectal surgery. A randomized trial.

A randomized trial including 294 patients was performed to evaluate the prophylactic effect of single vs. multiple doses of antibiotics in elective colorectal surgery. All patients received 1.5 g metronidazole and 3.0 g ampicillin peroperatively and were randomized to: no further prophylactic antibiotic treatment, or ampicillin 1 g X 3 and metronidazole 0.5 g X 3 given intravenously during the second and third postoperative days. Deep wound infection was seen in 9/149 (6 percent) receiving a single dose and in 8/145 (6 percent) receiving multiple doses. No differences were found in the two groups between frequencies of anastomotic dehiscences, intra-abdominal abscesses, sepsis, and pulmonary infections. The two groups were similar according to distribution of sex, age, diagnosis, and type of surgery. A single peroperative dose of metronidazole and ampicillin is a simple and satisfactory antibiotic prophylaxis in elective colorectal surgery.

Topical ampicillin in addition to a systemic antibiotic prophylaxis in elective colorectal surgery. A prospective randomized study.

Prophylactic use of topical ampicillin in addition to intravenous ampicillin and metronidazole was studied in a randomized trial including 203 consecutive patients undergoing elective colorectal surgery. All received ampicillin, 1 g X 3, and metronidazole, 0.5 g X 3, intravenously for at least three days from induction of anesthesia, and 105 also received topical ampicillin, 1 g, in each of the surgical wounds. Deep wound infection or dehiscence was seen in 12 of 105 having both administrations of antibiotics, and in nine of 98 having only intravenous antibiotics. The two groups were similar according to distribution of sex, age, type of surgery, and efficiency of bowel preparation. Topical ampicillin should be omitted in elective colorectal surgery when systemic prophylaxis with ampicillin and metronidazole is used.

Maximal local and minimal systemic cytokine response to colorectal surgery: the influence of perioperative filgrastim.

Thirty consecutive patients scheduled for elective colorectal surgery were prospectively randomized to receive either filgrastim [the recombinant human form of granulocyte colony-stimulating factor (r-metHu-G-CSF)] or placebo blindly. The levels of interleukin (IL-)1beta, tumour necrosis factor-alpha (TNF-alpha), IL-6, IL-8, transforming growth factor-beta (TGF-beta), and IL-10 were determined 5 and 24 h postoperatively from peripheral blood, peritoneal fluid, and wound fluid. The concentrations of all the measured cytokines were enormously higher locally at the operative site than in the systemic circulation. The only difference between the two medication groups was the lower concentration of IL-8 in peripheral blood in the filgrastim-treated patients. The present study shows abundant release of pro- and anti-inflammatory cytokines into the wound and the peritoneal cavity after abdominal surgery. The systemic response to surgery seems to be a secondary and minor reflection of local events. Filgrastim did not have any effect on the studied local cytokine levels at the operative site.

Taurolidine peritoneal lavage as prophylaxis against infection after elective colorectal surgery.

A total of 300 patients undergoing elective colorectal surgery over a 3-year period were randomly assigned to receive intraoperative peritoneal lavage with either taurolidine or saline. Culture swabs were taken from the region of surgery before and after lavage and the development of postoperative infection monitored. Of the positive culture swabs before lavage, a significantly higher proportion were negative after lavage with taurolidine than after that with saline. However, there was no difference in the incidence of postoperative infection between groups, suggesting that taurolidine intraoperative peritoneal lavage confers no clinical benefit over that with saline.

Ceftriaxone single dose versus ceftazidime multiple doses in the prophylaxis of infection in colorectal surgery.

Sixty patients admitted to the hospital for colorectal surgery were randomly assigned to prophylaxis either with a single dose of ceftriaxone (Rocephin) i.v. plus metronidazole given 30 min prior to induction of anesthesia or with multiple doses of ceftazidime plus metronidazole given repeatedly every 8 h up to 24 h after surgery. The overall number of infections observed with the long-acting cephalosporin ceftriaxone was 4 (2 local and 2 remote), with the short-acting ceftazidime the number was 9 (5 local and 4 remote). Neither regimen was associated with adverse reactions.

[Preventive antibiotics in elective colorectal surgery].

At least every third patient undergoing elective colorectal surgery without antibiotic cover will develop one or more postoperative infectious complications. Using appropriate antimicrobial prophylaxis with agents effective against both aerobe and anaerobe microorganisms less than 4 per cent of the patients will have such problems. Systemic (i.v.) prophylaxis started immediately before or at induction of anaesthesia is the preferred method, giving maximal tissue concentrations of the agents during the contamination process. Short term prophylaxis, at least as effective as 5 days prophylaxis, will reduce toxicity, cost and resistance problems. Using agents with long half-lives (for instance doxycycline and tinidazole) single-dose prophylaxis is sufficient. Clinical resistance problems or reduced efficacy could not be demonstrated even after 10 years routine use of these agents in prophylaxis. Antibiotics necessary for treatment of serious infections should not be used in routine prophylaxis. Nitroimidazoles (metronidazole, tinidazole) represent an exception since development of resistance to these agents is extremely rare.

Single versus multiple dose doxycycline prophylaxis in elective colorectal surgery.

One hundred and two patients undergoing elective colorectal surgery were randomized in a prospective but "non-blind" way into two groups. The first group received 0.4 g of doxycycline preoperatively and the second group 0.2 g of doxycycline preoperatively and 0.1 g of doxycycline on the first, second and third postoperative day. All doxycycline was administered by intravenous infusion. The infection rate was 10% in the "one-dose" treatment group and 10% in the "four-dose" treatment group. It is thus concluded that 0.4 g of doxycycline preoperatively results in an acceptable rate of postoperative infections, which may be explained by the satisfactory concentration of doxycycline up till three days after administration. The advantage of "one-dose" treatment compared to "four-dose" treatment from practical and economical standpoints are obvious.

Tinidazole and doxycycline compared to doxycycline alone as prophylactic antimicrobial agents in elective colorectal surgery.

Forty-two patients admitted for elective colorectal surgery were given tinidazole and doxycycline or doxycycline alone as prophylactic antimicrobials in a double-blind study. There was altogether one abdominal wound infection (2.4%), and one patient developed a perineal fistula three months after the operation. No significant difference in postoperative infections between the two groups could be demonstrated. It is concluded that doxycycline seems effective in reducing wound sepsis after operations on the large intestine and that additional administration of tinidazole will yield little in prophylaxis.

Ticarcillin/clavulanic acid (Timentin) compared to metronidazole/netilmicin in preventing postoperative infection after elective colorectal surgery.

A randomized controlled trial was performed to compare the effectiveness of ticarcillin/clavulanic acid to metronidazole/netilmicin in preventing postoperative infections after elective colorectal surgery. Ninety-two patients were randomly allocated to receive three doses of ticarcillin, 3 g, with clavulanic acid, 100 mg every 8 hours, or three doses of metronidazole, 500 mg, and netilmicin, 80 mg intravenously every 8 hours. All patients received a mechanical bowel preparation with 3 L of Go-lytely solution. There were no operative deaths. Eight patients had wound infections--three in the ticarcillin/clavulanic acid group and five in the metronidazole/netilmicin group. One patient in the ticarcillin/clavulanic acid group had an intra-abdominal abscess. There were two anastomotic leaks, one in each group. Ticarcillin/clavulanic acid and metronidazole/netilmicin appear to be equally effective in preventing postoperative infections after elective colorectal surgery.

Ertapenem versus cefotetan prophylaxis in elective colorectal surgery.

BACKGROUND: Ertapenem, a long-acting carbapenem, may be an alternative to the recommended prophylactic antibiotic cefotetan. METHODS: In this randomized, double-blind trial, we assessed the efficacy and safety of antibiotic prophylaxis with ertapenem, as compared with cefotetan, in patients undergoing elective colorectal surgery. A successful outcome was defined as the absence of surgical-site infection, anastomotic leakage, or antibiotic use 4 weeks postoperatively. All adverse events were collected until 14 days after the administration of antibiotic prophylaxis. RESULTS: Of the 1002 patients randomly assigned to study groups, 901 (451 in the ertapenem group and 450 in the cefotetan group) qualified for the modified intention-to-treat analysis, and 672 (338 in the ertapenem group and 334 in the cefotetan group) were included in the per-protocol analysis. After adjustment for strata, in the modified intention-to-treat analysis, the rate of overall prophylactic failure was 40.2% in the ertapenem group and 50.9% in the cefotetan group (absolute difference, -10.7%; 95% confidence interval [CI], -17.1 to -4.2); in the per-protocol analysis, the failure rate was 28.0% in the ertapenem group and 42.8% in the cefotetan group (absolute difference, -14.8%; 95% CI, -21.9 to -7.5). Both analyses fulfilled statistical criteria for the superiority of ertapenem. In the modified intention-to-treat analysis, the most common reason for failure of prophylaxis in both groups was surgical-site infection: 17.1% in the ertapenem group and 26.2% in the cefotetan group (absolute difference, -9.1; 95% CI, -14.4 to -3.7). In the treated population, the overall incidence of Clostridium difficile infection was 1.7% in the ertapenem group and 0.6% in the cefotetan group (P=0.22). CONCLUSIONS: Ertapenem is more effective than cefotetan in the prevention of surgical-site infection in patients undergoing elective colorectal surgery but may be associated with an increase in C. difficile infection.

Quality control of colorectal surgery with an extensive complication registration system.

BACKGROUND/AIMS: Since 1996, a standard registration is used to obtain a clear understanding of the complications that occur after colorectal surgery. In our registration system the cause of a complication and the detrimental effect to the patient's health are coded. METHODS: The treatment of colorectal diseases was evaluated to analyze the quality of medical care. RESULTS: From 1996 to 2000, a total of 169 complications were documented in 108 of the 353 patients operated on. Leakage of the anastomosis occurred in 22 cases (6%) and wound infection occurred in 11 cases (3%). Most of the complications required no or little medical attention (n = 101, 59%). 51% of the complications could be attributed to the physical condition of the patient. Surgical complications were the cause in 31% of the cases and management problems in 16% of the cases. CONCLUSION: A registration system provides good insight into the frequency and severity of the complications after colorectal surgery. Extensive registration is mandatory to provide reliable information, comparing the results year by year. This provides the basis for continuous improvement of medical protocols on the surgical ward.

Internet use by colorectal surgery patients: a surgeon's tool for education and marketing.

The goal of this study is to understand the role of the Internet in the education and recruitment of patients within colorectal surgery practices. Surveys of Internet use were completed by 298 patients visiting five outpatient colorectal surgery clinics affiliated with the University of Southern California. Data collected included the patient's age, gender, level of education, zip code at home, type of clinic visited, and information on the respondent's Internet use. Overall, 20 per cent of the respondent patients visiting our clinics had used the Internet to research the medical condition that prompted their visit. Highest grade level completed (P < 0.001), age (P < 0.01), type of clinic (P < 0.001), and household income (P < 0.001) were all found to be associated with any prior use of the Internet whereas gender was not (P = 0.58). Among Internet users, only household income and frequent use of the Internet were associated with searching the Internet for medical information (P < 0.001). Ultimately, all of the Internet-using patients surveyed felt the medical information they found was "some what" or "very helpful." Understanding which patients "go online" to search for medical information is essential for surgeons who wish to use the Internet for marketing their practices and educating their patients.

Gasless laparoscopy-assisted colorectal surgery.

BACKGROUND: Laparoscopy has gained wide acceptance as a treatment modality in a variety of colonic and rectal disorders. Currently, most laparoscopic procedures are performed using a carbon dioxide (CO2) pneumoperitoneum, which can lead to cardiopulmonary loading and subsequent complications. The object of this study was to assess the feasibility of gasless laparoscopy-assisted colorectal surgery (GLACS) as an alternative method. METHODS: Patients with benign colonic lesions were enrolled in the study. The operative field was exposed with a subcutaneous wire lifting system. A small incision, ~5 cm in length, was made early in the operation. The surgeon operated through the trocar ports and this incision using both laparoscopic and conventional instruments. The cardiopulmonary responses of the patients were monitored continuously during the operation. RESULTS: Fifteen consecutive patients underwent GLACS. In two patients (13.3%), conversion to open surgery was necessary. The exposure and ease of the procedure were acceptable. However, when the patients were stratified into hemicolectomy and sigmoidectomy groups, GLACS scored more favorably in the sigmoidectomy group. There were no operative deaths. One minor complication developed postoperatively. All of the patients recovered uneventfully, with return of bowel function in 2.8 +/- 0.1 days. The mean postoperative hospital stay was 6.4 +/- 0.4 days. The cardiac and pulmonary status of the patients remained stable during the operation. CONCLUSION: Gasless laparoscopy-assisted colorectal surgery is technically feasible; thus, it provides an alternative means for the performance of minimal-access surgery.

A survey of antimicrobial prophylaxis in elective colorectal surgery in New Zealand.

In 1988 a survey of New Zealand general surgeons was conducted, by post, on the subject of routine antimicrobial prophylaxis for elective colorectal surgery. Surgeons who gave routine prophylaxis were asked for details of their regimens; those who did not were asked for their reasons. One hundred and seventy-five questionnaires were distributed and 167 were returned. Of these, 124 came from surgeons with a colorectal practice, and 118 of the 124 surgeons satisfactorily completed the questionnaire. Routine antimicrobial prophylaxis was given by 96.6% (114 of 118). Of the 114 surgeons prescribing prophylaxis, one antimicrobial agent was used by 36.8%, two were employed by 53.5% and three or five were used by the remainder. The most commonly used (74.6%) antimicrobial agents were cephalosporins which were prescribed, alone or in combination with a nitroimidazole. The most frequent duration (46.4%) of antimicrobial administration was a combination of both the peri- and postoperative periods. When antimicrobial spectrum, route and duration of administration were all taken into account, 49.1% (56 of 114) were considered to give satisfactory regimens. Excessively protracted administration was the most frequent reason for unsatisfactory classification. The results of this survey demonstrate serious deficiencies in the practice of antimicrobial prophylaxis in elective colorectal surgery. These should be addressed through a programme of continuing education.

Prospective comparative study of cefotetan with piperacillin for prophylaxis against infection in elective colorectal surgery.

This study compared one dose of cefotetan with three doses of piperacillin as prophylaxis against wound infection in 153 patients undergoing elective colorectal surgery. The patients were randomized into two groups: the first received 2 g cefotetan intravenously with induction of anaesthesia (n = 75), and the second received three doses of 2 g piperacillin (n = 78). Wound infection was defined as the presence of an abscess or discharging pus from the wound. In the cefotetan group there were 14 (19%) wound infections and 13 (17%) in the piperacillin group. There were three septic deaths, one in the cefotetan group and two in the piperacillin group. Both groups were comparable with regard to age, sex, nature of pathology and pre- and perioperative risk factors. No significant haematological or biochemical abnormalities were detected. The only adverse reaction was one patient who had an allergic reaction (rash) to piperacillin. These data suggest that single-dose cefotetan is as effective as triple-dose piperacillin in prophylaxis against infection in elective colorectal surgery.

Comparison of prophylactic ampicillin/sulbactam with gentamicin and metronidazole in elective colorectal surgery: a randomized clinical study.

A randomized control clinical study was conducted to compare the effectiveness of prophylactic ampicillin/sulbactam in preventing wound infection after elective colorectal surgery with a combination of gentamicin and metronidazole. Over a 2-year period, 143 patients were recruited, but 15 patients were subsequently excluded due to the use of additional antibiotics for the treatment of pulmonary or urinary infection or early postoperative death without wound infection. Of the 128 evaluable patients, six of the 63 patients (9.5%) in the ampicillin/sulbactam group and seven of the 65 patients (10.7%) in the gentamicin and metronidazole group developed wound infection. We conclude that prophylactic ampicillin/sulbactam is effective in reducing the risk of wound infection following colorectal surgery.
