Reoperation as a quality indicator in colorectal surgery: a population-based analysis.

OBJECTIVE: To describe unplanned procedures following colorectal cancer surgery that might be used as intermediate outcome measures, and to determine their association with mortality and length of stay. SUMMARY BACKGROUND: Variation in the quality of surgical care, especially for common illnesses like colorectal cancer, has received increasing attention. Nonfatal complications resulting in procedural interventions are likely to play a role in poor outcomes but have not been well explored. METHODS: Cohort analysis of 26,638 stage I to III colorectal cancer patients in the 1992 to 1996 SEER-Medicare database. INDEPENDENT VARIABLES: sociodemographics, tumor characteristics, comorbidity, and acuity. PRIMARY OUTCOME: postoperative procedural intervention. ANALYSIS: Logistic regression identified patient characteristics predicting postoperative procedures and the adjusted risk of 30-day mortality and prolonged hospitalization among patients with postoperative procedures. RESULTS: A total of 5.8% of patients required postoperative intervention. Patient characteristics had little impact on the frequency of postoperative procedures, except for acute medical conditions, including bowel perforation (relative risk [RR] = 3.0, 95% confidence interval [CI] = 2.5-3.6), obstruction (RR = 1.6; 95% CI = 1.4-1.8), and emergent admission (RR = 1.3; 95% CI = 1.1-1.4). After a postoperative procedure, patients were more likely to experience early mortality (RR = 2.4; 95% CI = 2.1-2.9) and prolonged hospitalization (RR = 2.2; 95% CI = 2.1-2.4). The most common interventions were performed for abdominal infection (31.7%; RR mortality = 2.9; 95% CI = 2.3-3.7), wound complications (21.1%; RR mortality = 0.7; 95% CI = 0.4-1.3), and organ injury (18.7%; RR mortality = 1.6; 95% CI = 1.1-2.3). CONCLUSIONS: Postoperative complications requiring additional procedures among colorectal cancer patients correlate with established measures of surgical quality. Prospective tracking of postoperative procedures as complication markers may facilitate outcome studies and quality improvement programs.

Changes in hemoglobin and hematocrit levels following orthognathic surgery of the mandible.

Red blood cell mass has been shown to recover rapidly with great decreases, as occurs in orthognathic surgery. However, blood loss during bilateral sagittal split osteotomy is considered minimal. The purpose of this study was to verify changes in hemoglobin (Hb) and hematocrit (Ht) levels following orthognathic surgery of the mandible. Data from 12 patients with a mean age of 27.5 years, from both genders, that were submitted to bilateral sagittal split osteotomy in the prognathism reduction were evaluated. No patient received blood transfusion during the procedure nor postoperatively. Procedures were performed by the same surgeon, with the use of reciprocating and sagittal saws. Levels of Hb and Ht were obtained in preoperative, one day postsurgery, and one, three and six weeks postoperatively. Statistical analyses were used to verify the difference in each group, and between periods. Patients lost a mean decrease in Hb of 2.0 g/dl, and in Ht of 5.2%. There was significant difference as to the levels of Hb (p=0.002) and Ht (p=0.010). These levels presented significant changes from immediate postoperative to six weeks for Hb, and to three weeks for Ht. It was concluded that a slow recovery of hemoglobin and hematocrit levels occurred following orthognathic surgery of the mandible.

[IKOP-Infection control in the operating theatreConsensus on the theme "Barrier measures during operations and invasive procedures"].

Postoperative surgical site infections remain frequent despite intensive control programs. With rising numbers of operations and invasive procedures in the outpatient setting and in immunocompromised patients, the prevention of wound infections presents a rapidly growing challenge to the medical community. Barrier measures including drapes and surgical gowns to prevent wound contamination, have clearly reduced the rate of wound infections. The optimal material characteristics for operating gowns and drapes are well defined, but there is still a long running controversy on the use of single-use versus reusable materials. We review the efficacy and ecological impacts of these different approaches. Currently no superiority of any of these approaches with regard to either efficacy or ecological impact can be found. The European Union has recently published a series of mandatory standards to specify material characteristics of barrier materials used in operating theatres (EN 13795). Their scope include production standards of these materials as well as specific processes in auditing their characteristics. The implementation of these norms will clearly present a challenge to European hospitals but will lead to better material characteristics in the end.

[Bladder drainage in patients undergoing the Pereyra surgical procedure].

Postoperative acute urinary retention was evaluated in the patients who underwent Pereyra procedure. Comparison of suprapubic and urethral catheterization. Between January 1994 and July 1995, fifty two patients with urinary stress incontinence underwent Pereyra procedure, 31 female patient with suprapubic drainage (cistofix Ch 15) and 17 urethral catherization with a latex foley catheter. Sponatneous micturition and urinary retention was evaluated until the catheter was removed. Mean age was 43.8 years (32 a 66), the duration of suprapubic vesical drainage with suprapubic catheter were 3 days in 58.6% of the patients, and more than 3 days in 41.29%. Recatheterizacion in the patients with urethral drainage was more frequent. Urinary retention after 7 days was present in 23.99% with suprapubic vesical drainage and 28.5% with urethral catheter. Recatheterization is more frequent in patients with urethral catheter.

Incidence of wound infection for common general surgical procedures.

Postoperative wound infection remains a ubiquitous problem with serious consequences, especially with regard to prolonged convalescence and in a source of physical and financial burden to the patient. Wound infection occurred in 13 of 1,346 of the patients during a single recent 12 month period with commonly performed surgical procedures at a large midwestern hospital. The bacteriologic findings of these infections was diverse.

Surgeon and hospital characteristics as predictors of major adverse outcomes following colon cancer surgery: understanding the volume-outcome relationship.

HYPOTHESIS: Although numerous studies have demonstrated an association between surgical volume and improved outcome in cancer surgery, the specific structures and mechanisms of care that are associated with volume and lead to improved outcomes remain poorly defined. We hypothesize that there are modifiable surgeon and hospital characteristics that explain observed volume-outcome relationships. DESIGN: Retrospective cohort study. SETTING: Surveillance, Epidemiology, and End Results cancer registry areas. PATIENTS: Patients aged 66 years and older, diagnosed and surgically treated for stage I, II, or III colon cancer between 1992 and 1996 (n = 22 672). MAIN OUTCOME MEASURES: Thirty-day postoperative mortality and 30-day postoperative procedural interventions, including reoperation and image-guided percutaneous procedures. RESULTS: Surgeon volume, but not hospital volume, is a significant predictor of postoperative procedural intervention (adjusted odds ratio for very high-volume surgeons vs low-volume surgeons, 0.79; 95% confidence interval, 0.64-0.98). In the unadjusted analyses, high hospital volume (odds ratio, 0.67; 95% confidence interval, 0.56-0.81) and very high hospital volume (odds ratio, 0.65; 95% confidence interval, 0.54-0.79) is associated with lower postoperative mortality. Postoperative procedural intervention is not a significant mediator of the relationship between hospital volume and mortality. A single variable-the presence of sophisticated clinical services-was the most important explanatory variable underlying the relationship between hospital volume and mortality. CONCLUSIONS: Very high surgeon volume is associated with a reduction in surgical complications. However, the association between increasing hospital volume and postoperative mortality appears to derive mainly from a full spectrum of clinical services that may facilitate the prompt recognition and treatment of complications.

Preoperative skin testing of materials used in surgical procedures.

Postoperative skin complications increase health care costs and cause patient suffering. In the OR, patients are exposed to materials with adhesive substances that have the potential to cause allergic or toxic effects on the skin. Intraoperatively and postoperatively, these reactions can result in skin complications. The objective of this study was to investigate the incidence of skin reactions in connection with the application of different materials. Skin reactions after preoperative skin testing occurred in 3% to 50% of patients with atopic or contact eczema, allergy, or asthma in their medical history.

A comparison of two skin preps used in cardiac surgical procedures.

Postoperative surgical site infections contribute significantly to increased patient morbidity and mortality rates and unnecessary hospital costs. Effective and efficient preoperative patient skin preparation is an important perioperative nursing intervention that decreases the number of wound contaminants and reduces the risks for postoperative surgical site infections. This study examined the effectiveness and time and material costs of two preoperative patient skin prep methods (ie, isopropyl alcohol prep/iodophor-impregnated adhesive drape method, iodophor scrub and paint prep/plain adhesive drape method). The isopropyl alcohol prep/iodophor-impregnated adhesive drape method clinically was as effective as the iodophor scrub and paint prep/plain adhesive drape method, more cost-effective when time and materials were compared, and less cost-effective when materials alone were compared. To make appropriate decisions about the use of preoperative patient skin prep methods, perioperative nurse managers and staff members need to examine and determine whether costs in time or materials have the greater impact on their surgical settings.

[Post-aggression metabolism and peridural anesthesia: modification of catabolism by anesthesia procedures?].

Postoperative catabolic state of metabolism represents a danger for patients in regard to protein degradation. As postoperative nutrition seems already quite optimal, we examined if anaesthesia, predominantly peridural anaesthesia, would be able to reduce postaggressive metabolism. 20 patients with gastrectomy or subtotal gastric resection were randomized either for a combined anaesthesia with PDA and intubation or for balanced fentanyl analgesia. In both groups the typical characteristics of postaggressive metabolism could be demonstrated without any difference.

[Recording of the surgical procedures and postoperative complications in general surgery].

With selected examples from general surgery, a better statistical elaboration of patient's data by means of operation and complication classification is demonstrated. The use of an operation and a complication key is presented. The advantage of such a classification key in documentation is the possibility of maintaining an accurate yearly review of all therapeutical methods in surgery.

[Diagnostic procedure in postoperative complications].

17% of postoperative ICU patients develop postoperative complications. In 84% of cases, complications are related to surgery, in 16% they are not. The main postoperative surgical complications are abdominal sepsis (65%), postoperative bleeding (25%), and bowel obstruction (7%). Therefore, the primary objective of postoperative investigations must be to check the sites of operation. Bedside procedures are examination of drainage fluid, sonography, endoscopy, and X-ray (gastrografin swallow). The diagnostic value of these procedures is 80%. Other diagnostic procedures include CT, angiography, and diagnostic laparatomy.

Fenestration improves clinical outcome of the fontan procedure: a prospective, randomized study.

BACKGROUND: The Fontan procedure is the definitive operation for palliation of complex congenital heart disease with single-ventricle physiology. Fenestration of the Fontan circuit allows for shunting of deoxygenated blood to the systemic circulation. This procedure improved the clinical outcomes of patients who are at high risk for poor Fontan results. However, it is controversial whether fenestration is beneficial for standard-risk patients. METHODS AND RESULTS: This prospective, randomized trial evaluated the clinical utility of fenestration in patients with standard preoperative risk profiles for Fontan surgery. Forty-nine consecutive patients were assigned to undergo either a fenestrated (25 patients) or nonfenestrated (24 patients) Fontan procedure. The fenestrated and nonfenestrated groups were comparable with respect to age (P=0.944), body surface area (P=0.250), number of preoperative risk factors for poor outcome (P=0.681), cardiopulmonary bypass time (P=0.302), number of patients who required aortic cross-clamping (P=0.240), preoperative oxygen saturation (P=0.101), and number of patients with dominant left ventricular morphology (P=0.534). Patients in the fenestrated group had 55% less total chest tube drainage (P=0.036), 41% shorter total hospitalization (P=0.018), and 67% fewer additional procedures in the postoperative period (P=0.006) than those in the nonfenestrated group. CONCLUSIONS: Baffle fenestration performed at the time of Fontan surgery improves short-term outcome in standard-risk patients by decreasing pleural drainage, hospital length of stay, and need for additional postoperative procedures.

Classification of bone healing after intertrochanteric osteotomies. Consequences for the surgical procedure and postoperative rehabilitation.

Intertrochanteric osteotomies produce a rate of 1 to 7% delayed union and pseudarthrosis, mainly as a result of the quality of the surgical procedure employed. In this retrospective and prospective study we have divided the models of bone healing after intertrochanteric osteotomy into 4 groups based on the postoperative x rays, and have taken into account only the factors of sclerosis, radiolucency and fragment contact in the osteotomy plane. This grouping enables us to evaluate the quality of the surgical procedure and to predict the postoperative course at an early stage, thus facilitating timely modification of the postoperative rehabilitation.

Results after surgery in undifferentiated large cell carcinoma of the lung: the role of neuroendocrine expression.

OBJECTIVE: The objective of this study was to define the incidence of light microscopically undifferentiated large cell carcinomas, to analyze tumor stages, types of resections necessary and postsurgical survival. Additionally we tried to evaluate whether or not neuroendocrine expression influences the biological behavior of these tumors. METHODS: Light microscopic specimens of 105 patients having undergone surgery for undifferentiated large cell carcinoma were reviewed following the 1981 WHO criteria. Fifty eight cases were excluded because elements of adeno- or squamous cell carcinoma, neuroendocrine or combined patterns of histological differentiation were observed. The remaining 47 cases of pure undifferentiated large cell carcinoma were evaluated immunohistochemically for neuroendocrine differentiation using a combination of the markers neuron specific enolase, synaptophysin and chromogranin A. The hospital charts of the patients were analyzed retrospectively recording tumor stage, operative procedure, postoperative complications, postoperative adjuvant treatment procedures, actual tumor state and survival time. RESULTS: Thirteen patients (27.7%) had postsurgical tumor stage I, 5 (10.6%) stage II, 15 (31.9%) stage IIIA, 9 (19.1%) stage IIIB, and 5 (10.6%) stage IV. In 46 of 47 patients resections of lung parenchyma were performed (wedge resection n = 5, segmental resection n = 1, lobectomy n = 27, bilobectomy n = 3, pneumonectomy n = 10), in 6 patients combined with broncho- and/or angioplastic procedures. At the time of chart review 20 (42.5%) patients were still alive. The cause of death in the remaining patients was recurrent lung cancer in the majority of cases (24 or 92.30%). The overall mean survival of the 46 patients undergoing parenchymal resections was 19 months, the 3-year survival rate 31.7%. The immunohistochemical examination demonstrated expression of neuron specific enolase in 15 cases. Synaptophysin and chromogranin A were not detected in any case. For these 15 patients the mean survival was 25.6 months (+/- 4.3) and the 1-year survival rate 67% (confidence interval 43-91%) compared to 13.8 (+/- 2.1) months and 33.5% (confidence interval 15.3-51.7%) in the remainder. The difference was not significant (P = 0.06). CONCLUSIONS: The light microscopic diagnosis of undifferentiated large cell carcinoma revealed to be subject to considerable interobserver variability. Undifferentiated large cell carcinoma takes a more unfavorable clinical course than other non-small cell carcinomas. Despite lack of statistical significance, expression of neuron specific enolase appeared to be associated with less aggressive biological behavior of the respective neoplasms. Immunohistochemical evaluation of undifferentiated large cell carcinomas using a combination of neuron specific enolase, chromogranin A, and synaptophysin did not provide more therapeutically relevant information than that obtained by light microscopic assessment.

[Primary renal plasmacytoma. A case report].

We describe a patient with a primary renal plasmacytoma. In the literature available, only six clinical cases have been reported. A 64-year-old patient is presented who had the clinical signs of a renal cell carcinoma. Histological examination after nephrectomy, however, revealed a plasmacytoma. Based on this case, we discuss how one should proceed in this disease. Primary renal plasmacytoma can be tentatively diagnosed preoperatively only in the presence of paraproteinemia or Bence-Jones proteinuria, as it cannot be distinguished from other renal tumors by imaging procedures. Postoperatively, further staging procedures must rule out bone involvement (solitary myeloma or multiple myeloma). Nephrectomy is required in patients with plasmacytoma only if renal complications occur.

Recombinant factor VIIa for patients with inhibitors to factor VIII or IX or factor VII deficiency.

Inhibitors to factor VIII (FVIII) or IX (FIX) in patients with haemophilia A or B create a challenging problem for the treatment of these patients. Recombinant FVIIa (rFVIIa; NovoSeven, Novo Nordisk A/S, Bagsvaerd, Denmark) is a realistic treatment option, owing to its specific mode of action and lack of immunogenicity. This was a multicentre, open-label, compassionate-use trial in patients with severe haemophilia A (FVIII:C < 1%) or B (FIX:C < 1%) with inhibitors, acquired antibodies to FVIII or FIX, or FVII deficiency (FVII:C < 5%), for whom alternative therapies had failed or were contraindicated. Patients received rFVIIa treatment for life- or limb-threatening bleeding episodes or for coverage during essential surgery. The mean rFVIIa dose was approximately 90 microg kg-1 for haemophilia A/B and acquired inhibitor patients, and 25 microg kg-1 for FVII-deficient patients. Efficacy data for 67 treatment episodes (45 bleeding episodes, 22 surgical procedures) are presented; seven patients were treated for a concurrent serious bleeding episode and surgical procedure. At the end of treatment, rFVIIa was effective or partially effective in 85% of serious bleeding episodes. During surgery, bleeding was assessed as none or less than or equivalent to normal in 91% of surgical procedures; postoperatively, 91% of procedures were associated with no or minimal oozing. During 60 separate treatment episodes, 26 adverse events (22 nonserious, four serious) were reported in 15 patients, during 17 bleeding episodes or surgical procedures. Only 10 were considered as having a possible, probable, or unknown relationship with rFVIIa; of these, fever (n=2) and thrombophlebitis (n=3) were the most common. There was no evidence of disseminated intravascular coagulation. In conclusion, rFVIIa is an effective, well-tolerated treatment for serious bleeding episodes and bleeding associated with surgical procedures in patients with severe haemophilia A/B with inhibitors, acquired inhibitors, or FVII deficiency.

Sterilization and its consequences.

UNLABELLED: The purpose of this review is to analyze critically the two techniques of sterilization (bilateral tubal ligation [BTL] and vasectomy) so that a physician may provide informed consent about methods of sterilization. A MEDLINE search and extensive review of published literature dating back to 1966 was undertaken to compare preoperative counseling, operative procedures, postoperative complications, procedure-related costs, psychosocial consequences, and feasibility of reversal between BTL and a vasectomy. Compared with a vasectomy, BTL is 20 times more likely to have major complications, 10 to 37 times more likely to fail, and cost three times as much. Moreover, the procedure-related mortality, although rare, is 12 times higher with sterilization of the woman than of the man. Despite these advantages, 300,000 more BTLs were done in 1987 than vasectomies. In 1987, there were 976,000 sterilizations (65 percent BTLs and 35 percent vasectomies) with an overall cost of $1.8 billion. Over $260 million could have been saved if equal numbers of vasectomies and BTLs had been performed, or more than $800 million if 80 percent had been vasectomies, as was the case in 1971. The safest, most efficacious, and least expensive method of sterilization is vasectomy. For these reasons, physicians should recommend vasectomy when providing counseling on sterilization, despite the popularity of BTL. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians LEARNING OBJECTIVES: After completion of this article, the reader will be able to predict the failure rates and likelihood of successful reversal of tubal ligation and vasectomy; to recall the difference in cost between the two sterilization procedures, and to describe the short-term and long-term complications associated with each of the two methods of sterilization.
