Self-appraisal hierarchical task analysis of laparoscopic surgery performed by expert surgeons.

BACKGROUND: Evaluation of technical skill is notoriously difficult because of the subjectivity and time-consuming expert analysis. No ongoing evaluation scheme exists to assess the continuing competency of surgeons. This study examined whether surgeons' self-assessment accurately reflects their actual surgical technique. METHODS: Hierarchical task analysis (HTA) of laparoscopic cholecystectomy was constructed. Ten expert surgeons were asked to modify the HTA for their own technique. The HTAs of these surgeons then were compared with their actual operations, which had been recorded and assessed by two observers. RESULTS: A total of 40 operations were assessed. All the gallbladders subjected to surgery were classified as grades 1 to 3. The mean interrater reliability for the two observers had a k value of 0.84 (p < 0.05), and the mean intrarater reliability between surgeons and observers had a k value of 0.79 (p < 0.05). CONCLUSIONS: Surgeons' self-evaluation is accurate for technical skills aspects of their operations. This study demonstrates that self-appraisal using HTA is feasible, accurate, and practical. The authors aim to increase the numbers in their study and also to recruit residents.

The effect of a second-generation 3D endoscope on the laparoscopic precision of novices and experienced surgeons.

BACKGROUND: Endoscopic surgeons rely on visual feedback to control their movements but lack stereopsis, an important depth cue. Previous three-dimensional (3D) systems alternated images on a two-dimensional (2D) screen, which was uncomfortable for surgeons. A second-generation 3D system provides continuous stereoscopic images on a monitor suspended at arm's length. We studied its effect on the laparoscopic precision of novices and experienced surgeons. METHODS: Experienced laparoscopic surgeons (n = 12) and novices (n = 16) performed a total of 672 tasks in 2D, 3D, and under direct vision. Precision was assessed using the Imperial College Surgical Assessment Device (ICSAD), which generates objective scores of performance by analyzing the movements of surgical instruments. RESULTS: We found that 2D endoscopic vision impaired performance by 35-100% when compared with direct vision, whereas 3D reduced this endoscopic handicap by 41-53% in novices and experienced surgeons (p < 0.03). No side effects were reported with the new 3D system. Even in 2D, novices performed better with an image at arm's length (p < 0. 03). CONCLUSIONS: Second-generation 3D significantly improved the laparoscopic precision of novices and experienced surgeons, without the side effects reported from previous systems. This technology is expected to improve the ease and safety of laparoscopic surgery.

Closer to an ideal solution for inguinal hernia repair: comparison between general surgeons and hernia specialists.

BACKGROUND: It is accepted a priori that specialists of hernia surgery have better results than general surgeons who use the same or different techniques as part of their complete surgical repertoire. METHODS: Results of general surgeons trained in the technique of hernia repair using a bilayer connected mesh device (BCMD) was compared to results of specialists and other general surgeons who used other techniques. RESULTS: One report from hernia specialists and three additional reports from trained general surgeons showed similar results using a BCMD. These results were better than results of all other mesh repairs. DISCUSSION: This study shows the value of surgeon-training as well as the value in the design of a particular mesh device for hernia repair. The three components of this device offer three separate, yet connected, barriers to the formation of a recurrent hernia. CONCLUSION: General surgeons trained to use a bilayer mesh device repeatedly duplicated the results of specialists who used it.

Relationship between surgeon caseload and sphincter preservation in patients with rectal cancer.

PURPOSE: The aim of this study was to determine by means of a national database whether higher surgeon caseload correlates with greater utilization of sphincter-sparing procedures than of abdominoperineal resections in treatment of patients with rectal cancer. METHODS: Patients with a primary International Classification of Diseases-9 diagnosis code of rectal cancer who underwent a sphincter-sparing procedure or abdominoperineal resection were selected from the 1997 Nationwide Inpatient Sample, a database that represents 20 percent of all U.S. community hospital discharges. Multivariable logistic regression models were used on a 20 percent sample of this database to estimate the risk-adjusted relationship between surgeon caseload volume and the odds of receiving a sphincter-sparing procedure. All models were adjusted for age, gender, race, hospital region, and patient comorbidity. RESULTS: The study population (n = 477) was 70.4 percent white and 57.9 percent male with an average age of 67.6 years. The mean Deyo comorbidity score was 7.0. Patients treated by surgeons in the highest-volume category (> or =10 rectal cancer surgeries per year) compared with those treated by surgeons in the lowest-volume category (1-3 rectal cancer surgeries per year) were significantly more likely to undergo a sphincter-sparing procedure, after adjustment for other covariates (odds ratio = 5.05; 95 percent confidence interval, 2.5-10.22). CONCLUSION: This analysis suggests that rectal cancer patients treated by high-volume surgeons are five times more likely to undergo sphincter-sparing procedures than those treated by low-volume surgeon. This has significant implications for those seeking a sphincter-preserving option for the treatment of their rectal cancer.

The importance of colonoscopy in colorectal surgeons' practices: results of a survey.

PURPOSE: The role of colonoscopy in the prevention of colorectal cancer has been accepted, not only by the medical community but by the federal government as well. This study sought to document the current role of colonoscopy in the practices of colorectal surgeons. METHODS: A survey was mailed to members of The American Society of Colon and Rectal Surgeons detailing the scope of colonoscopy in their practices. RESULTS: Surveys were mailed to 1,800 members of The American Society of Colon and Rectal Surgeons; responses were received from 778 (43.2 percent). The mean age was 48 +/- 10 (range, 27-79) years; the mean number of years in practice was 14 +/- 10 (range, 0.2-48). The majority of respondents (91 percent) were male. Responses were received from 47 U.S. states and 30 foreign countries. Seventy-four respondents (9.5 percent) reported not performing colonoscopy; the most common reason cited was "referring physicians' preference" (45 percent). Seven-hundred four respondents (90.5 percent) reported performing colonoscopy as part of their clinical practice and reported an average of 41 +/- 41 colonoscopies in the last month (range, 0-635) and 457 +/- 486 in the last year (range, 2-7,000). Colonoscopy accounted for 23 +/- 16 percent of responding physicians' clinical time (range, 1-100 percent) and 27 +/- 19 percent of total charges (range, 0-100 percent). Nearly all respondents (97 percent) anticipated maintaining or increasing their volume of colonoscopy in the coming year. Eighty-four percent of respondents reported receiving some or all of their training in colonoscopy during a colon and rectal surgery fellowship. More than one-half of respondents (55 percent) believed that there should be more of an emphasis on colonoscopy on the American Board of Colon and Rectal Surgery board examination, and 81 percent believed that the annual meeting of The American Society of Colon and Rectal Surgeons should include lectures and/or courses covering colonoscopy. CONCLUSIONS: Colonoscopy plays a major role in the practices of colorectal surgeons across the world, accounting for approximately one-quarter of clinical time and total charges. Based on the expectation that this trend will continue, The American Society of Colon and Rectal Surgeons needs to aggressively support its members not only in the technical aspects of colonoscopy but also in the practice management issues.

Surgical outcome for resident and attending surgeons.

We asked whether surgical process and outcome differ for physicians in postgraduate training supervised by attending surgeons compared with attending surgeons alone. All appendectomies performed during a 2 year period in a 320 bed voluntary hospital where either the admitting diagnosis or the preoperative diagnosis suggested acute appendicitis were included in the study. Data were abstracted from medical records and pathology reports. One hundred fifty-four cases of primary appendectomy were reviewed. In 97 cases, 1 of 9 attending physicians was listed as chief surgeon; in 57 cases, 1 of 15 resident physicians was listed as chief surgeon. There were no significant differences between the two patient groups according to age and sex. There was no difference between attending resident physicians in accuracy of diagnosis. Despite a pathologically normal appendix, attending surgeons in six cases and residents in two cases listed a discharge diagnosis of appendicitis. The average length of stay was 8.8 days for attending surgeons' cases and 7.1 days for residents' cases (t = 1.09, p = 0.29). The postoperative complication rates were 24 percent for attendings' cases and 12 percent for residents' cases (chi-square = 2.31, p = 0.16). We conclude that there is no appreciable difference in either the process or the outcome of care for patients undergoing appendectomy whether the operation is performed by an attending physician or a resident physician supervised by an attending physician.

Volume requirements for cardiac surgery credentialing: a critical examination. The Ad Hoc Committee on Cardiac Surgery Credentialing of The Society of Thoracic Surgeons.

New volume requirements for coronary artery bypass grafting are being imposed on cardiac surgeons by hospitals, managed care groups, and others. The rationale for this is unclear. The available literature as well as additional sources relating volume and outcomes in cardiac surgery were extensively reviewed and reexamined. There are no data to conclusively indicate that outcomes of cardiac operations are related to a specific minimum number of cases performed annually by a cardiac surgeon. Each cardiothoracic surgeon should participate in a national database that permits comparison of his or her outcomes on a risk-adjusted basis with other surgeons. Until conclusive data become available that link volume to outcome, volume should not be used as a criterion for credentialing of cardiac surgeons by hospitals, managed care groups, or others. Instead, each surgeon should be evaluated on his or her individual results.

Management of pediatric blunt splenic injury: comparison of pediatric and adult trauma surgeons.

The majority of injured children requiring hospitalization in the United States are cared for by nonpediatric surgeons. To determine whether there are differences in the management strategies (frequency of operative intervention) of pediatric and nonpediatric surgeons caring for children with blunt splenic injury, the data for children with this injury from the entire state of Vermont and the National Pediatric Trauma Registry were compared. From January 1, 1985 through December 31, 1991, 817 children (aged < 19 years) were entered into the study. There was operative intervention for splenic injury in 21% of the children managed by pediatric surgeons and in 52% of those managed by "adult" trauma surgeons (P < .05). This significance was maintained when operative rates were analyzed with control for injury severity score and age. The overall splenectomy rate was higher among cases treated by nonpediatric surgeons (24% v 13%; P < .05). In addition, previously reported factors (transfusion requirements, length of stay, hospital costs) used by opponents to nonoperative management were studied to determine management influence. Both transfusion requirement and hospital cost were lower for patients managed nonoperatively (P < .05). Length of hospital stay did not differ between the groups. Acute mortality rates were similar. The management of children with splenic injury must take into consideration the long-term morbidity associated with splenectomy as well as the acute operative morbidity. Today, adult trauma surgeons appear to manage children with blunt splenic injury with practice standards more appropriate for adult patients. Outcome analysis must include methods of care and their long- and short-term consequences to be considered valid.

Effect of surgeon's diagnosis on surgical wound infection rates.

To determine the impact of a surgeon's diagnosis of surgical wound infections on infection rates, during a 6-month period we prospectively examined patients undergoing surgical wound surveillance for any of four services (orthopedic surgery, general surgery, neurosurgery, or cardiovascular surgery). Criteria were judged as standardized if the infection control practitioner observed pus, redness, or drainage associated with positive culture or if a diagnosis of deep-seated infection was made. Surgeon's diagnosis was judged as a nonstandardized criterion. Using the Centers for Disease Control's criteria, we identified 113 surgical wound infections in 3024 patients undergoing surgical procedures in the four services. Of these, 95 (84%) met objective criteria (pus observed in 53%; drainage, redness, and positive culture in 20%; and deep-seated infection in 11%). In 18 patients (16%), the nonstandardized criterion alone was used for diagnosis. There was wide variation in use of the nonstandardized criterion, ranging from 5% of orthopedic infections to 21% of cardiovascular surgery infections and 40% of neurosurgical infections. For individual surgeons with at least one wound infection, the range of surgeon's diagnosis was up to 67%. We conclude that a surgeon's diagnosis can have a major impact on surgical wound infection rates; this impact is not borne equally among surgical services or individual surgeons.

Maxillectomy--to reconstruct or obturate? Results of a UK survey of oral and maxillofacial surgeons.

Post-maxillectomy defects may be restored either by surgical reconstruction or by prostheses and there is continuing controversy about the most appropriate method of rehabilitation in any particular case. A questionnaire was designed to assess the current practices of oral and maxillofacial surgeons in the UK after resection of the maxilla for malignant disease. Maxillectomies were carried out by 83% of surgeons; most surgeons do 1-5 cases a year; 38% of surgeons do reconstruct surgically, but only in 10% of cases. Only 65% of surgeons have access to the services of a restorative dentist; this did influence 19% of surgeons' decision about whether to reconstruct surgically or restore by prosthetic means.

Surgeons', nurses' and bereaved families' attitudes toward dying in the burn centre.

Because death of a patient is one of the most emotionally disruptive events in the health professionals' life as well as the bereaved, it was hypothesized that surgeons' and nurses' attitudes in the burn centre would interfere with their emotional support of the bereaved family. Consequently, we performed a psychometric assessment of the surgeons', nurses' and bereaved families' attitudes about death and dying in the burn centre. A psychometric instrument was developed and validated that assessed 13 surgical directors' of burn centres, 13 burn nurses' and nine bereaved family members' attitudes on death and dying in the burn centre. In the case of the bereaved family member, this instrument was complemented by interviews to ensure that the respondents understood each question. All surgeons and nurses were experienced health professionals working for an average of 12 +/- 8 years and 3 +/- 1 years respectively. The majority of burn surgeons (six) and the burn nurses (seven) found it to be emotionally difficult to support emotionally the bereaved family after the death of the patient. Over half the burn surgeons (seven) and nurses (seven) felt that the process of dealing with the bereaved family was different from that experienced in other hospital settings. The surgeons attributed this difference to the long duration of the patients' illnesses, while the nurses felt that it was due to the traumatic and painful qualities of burn injury. These emotional difficulties experienced by the staff in dealing with the dying patients were associated with a relatively low frequency of contact with the bereaved families after the patients' death.(ABSTRACT TRUNCATED AT 250 WORDS)

Is fear of anaphylactic shock discouraging surgeons from more widely adopting percutaneous and laparoscopic techniques in the treatment of liver hydatid cyst?

BACKGROUND: Sources of reports about laparoscopic and percutaneous treatment of liver hydatid cysts are limited to just a few countries. To address the reason behind this, we carried out a survey of 30 surgeons in northern Jordan. METHODS: A questionnaire was distributed to collect data regarding the surgical technique preferred by each surgeon. Further information was collected from those not adopting minimal-access techniques to determine their reasons for not doing so. RESULTS: Only 3 surgeons (10%) considered laparoscopy as the first line of treatment. Of the 27 surgeons who did not consider percutaneous or laparoscopic treatment, fear of anaphylaxis and/or dissemination was the main reason given by 21 surgeons (78%) for not using minimal access techniques. CONCLUSIONS: The seemingly exaggerated traditional fear of anaphylaxis seems to discourage surgeons from more widely adopting minimal access techniques for the treatment of hydatid cyst.

Geographic variation in sentinel node adaptation by practicing surgeons in Oregon.

BACKGROUND: The sentinel node biopsy (SNB) technique is an important tool in the diagnosis and treatment of breast cancer and melanoma. However, surgeons in Oregon have not universally adopted its use. METHODS: Mailed questionnaire. RESULTS: The response rate was 32%. Seventy-four (76%) of the surgical respondents perform routine SNB; 49% completed courses, and 32% learned the technique in residency. Sixty-one (89%) performed axillary dissection with their initial cases. It took 21 of 40 (52%) surgeons greater than a year to accrue 20 cases. Of 23 surgeons (24%) not performing SNB, 89% believed it was an important skill to obtain, and 70% thought they would benefit from proctoring opportunities. Six (26%) did not have technological support at their hospital. Surgeons at hospitals with less than 50 beds (P = .001) and at rural hospitals (P = .003) were less likely to perform SNB. CONCLUSION: The majority of urban general surgeons in Oregon use SNB in their practice. However, the incorporation of SNB for surgeons practicing in smaller hospitals and rural settings is less frequent than in the urban environment. As SNB becomes the standard of care, we need to overcome these barriers so that patients can have access to this procedure in their own communities.

Patterns of participation and successful patient recruitment to American College of Surgeons Oncology Group Z0010, a phase II trial for patients with early-stage breast cancer.

BACKGROUND: Historically, fewer than 5% of cancer patients enroll in clinical trials and lack of physician participation is a contributing factor. In 1999, the American College of Surgeons Oncology Group (ACOSOG) conducted a multicenter breast cancer trial evaluating the prognostic value of sentinel lymph node (SLN) and bone marrow micrometastases. This report elucidates factors influencing patient accrual. METHODS: Demographics of investigators (N = 198) and their success in accruing patients (N = 5327) were reviewed. ACOSOG Breast Committee members (N = 1136) were surveyed to identify factors influencing participation. RESULTS: Surgeons from 126 institutions participated in Z0010 (academic [48%], teaching-affiliated [20%], and community [29%] practices), and 28% of surgeons accrued 75% of the subjects. Twenty-four percent of surgeons accrued 75% of minority patients. Female surgeons accrued 24% of patients and accounted for 30% of investigators. On survey, 16% of respondents reported no prior experience with clinical trials and a number of factors were identified that influenced participation. CONCLUSIONS: ACOSOG successfully accrued 5327 patients to a SLN trial with surgeon participation from all practice settings. However, significant barriers to participation remain.

Has the trauma surgeon become house staff for the surgical subspecialist?

BACKGROUND: The role of the trauma surgeon is perceived to be mostly supportive of other procedure-oriented specialties. We designed this study to characterize the surgical and nonsurgical responsibilities of the contemporary trauma surgeon. METHODS: Trauma patients admitted to an urban academic level I trauma center were studied using trauma registry data for 2004. RESULTS: The large majority of patients admitted to trauma service has mild single-system injuries to 1 or 2 anatomic regions. Most (57%) did not have injuries to the neck, chest, or abdomen. Head and extremity injuries were present in 45% and 46% of patients, respectively. Surgeries were performed by orthopedists in 28%, trauma surgeons in 11%, and neurosurgeons in 6% of patients. CONCLUSIONS: The contemporary trauma surgeon has little surgical opportunity and provides a disproportionate amount of nonsurgical care in support of consultant specialists. This is a major deterrent to general surgeon interest in trauma care and must be addressed as the acute-care surgeon evolves.

The reliability between surgeons comparing arthroscopic and video evaluation of patients with shoulder impingement syndrome.

PURPOSE: To assess interobserver reliability between 2 surgeons, for real-time diagnostic arthroscopy and the corresponding videotape of shoulder pathology in patients with a clinical symptom complex consistent with shoulder impingement syndrome. TYPE OF STUDY: Prospective cohort. METHODS: Fifty-three patients with shoulder impingement syndrome underwent arthroscopic surgery by 1 of 2 experienced orthopaedic shoulder surgeons. All operations were videotaped. The surgeon who did not perform the surgery reviewed the videotaped procedure. The findings in the shoulder were independently documented by each surgeon on standardized shoulder information sheets. The video-review surgeon was blinded to the results of the arthroscopy and all preoperative workup information. The percentage agreement, kappa statistics, and correlations were calculated to assess the inter-rater reliability. RESULTS: The percentage agreement ranged from 100% for tendon ruptures to 39% when identifying acromion type. Interobserver kappa statistics were significant for all relevant structures with the exception of acromion type and coracoacromial ligament. CONCLUSIONS: There was satisfactory reliability between video and real-time arthroscopy. However, better objective definitions of pathology and standardization of arthroscopic techniques would improve these results. Videotaping of arthroscopy can be considered a useful educational tool, a way to improve communication between surgeons, and possibly a medicolegal tool when defining pathology in the shoulder. LEVEL OF EVIDENCE: Level II.

Surgeons' attitudes about communicating with patients and their families.

CONTEXT: Surgeons face difficult communication challenges with patients and their families. There is a need for improved education in communication skills, especially in giving bad news. Understanding surgeons' attitudes is the first step in designing effective education programs. OBJECTIVE: To determine surgeons' self-assessment of competence, rating of importance, and perceived need for training in communication skills relevant to patient care. DESIGN: Anonymous self-report mail survey of demographic information and attitudes toward 12 patient care-related communication skills. SETTING: San Diego County, California, a geographically distinct area of close to 3 million inhabitants receiving health care from over 6000 physicians. PARTICIPANTS: A total of 351 (43.4%) respondents from the 833 surgical specialists in the San Diego County Medical Society list of member and nonmember physicians. MAIN OUTCOME MEASURES: Measurement of surgeons' attitudes toward self-perceived competence, importance, need for training in the communication skills, and the influence of age, duration of practice, and surgical-specialty on attitudes. RESULTS: Most respondents rated their competence high except in 3 skills relating to a patient's death. They found all skills important and indicated a need for training in them. Younger surgeons rated their competence and the importance significantly lower in the 3 skills relating to a patient's death (p < 0.05). Critical care surgical specialists rated their competence and the importance higher in skills relating to breaking bad news and a patient's death than did the non-critical care group (p < 0.05). Older surgeons and critical care specialists also indicated a higher level of support for training in these skills. CONCLUSION: These results suggest that surgical specialists rate themselves as competent in effective communication, believe in its importance, and agree with the need for training. An organized approach to training in interaction skills, especially in giving bad news, is warranted.

Surgeon volume and postoperative mortality after oesophagectomy for cancer.

AIM: Oesophagectomy remains the curative treatment of choice for patients with localised oesophageal or cardia cancer, but severe postoperative complications are common. Our aim was to assess the association between surgeon volume and postoperative mortality after oesophagectomy. METHODS: Prospective, population-based study of Swedish residents diagnosed with oesophageal or cardia cancer, treated with oesophagectomy during the period April 2001 through December 2005. Details concerning patients, tumours, and surgery were collected from the Swedish Oesophageal and Cardia Cancer register. All 607 patients registered during the study period were included in the study. Risk of mortality 30 and 90 days after oesophagectomy was assessed using multivariable logistic regression, expressed in odds ratios (OR) with 95% confidence intervals (CI), adjusted for relevant covariates. RESULTS: The 30-day mortality in low-, medium-, and high-volume surgeon groups were 7.1%, 2.1%, and 2.6%, respectively. The corresponding 90-day figures were 11.4%, 4.8%, and 8.9%. Adjusted ORs for 30- and 90-day mortality were decreased non-significantly by 58% and 14%, respectively, among patients in the high-volume group, compared to the low-volume group (OR 0.42, 95% CI 0.10-1.80; OR 0.86, 95% CI 0.31-2.38). The mortality rates differed considerably between individual high-volume surgeons, but without any trend of further decreased risk with increasing volume among these surgeons (p values for trend 0.84 and 0.80 for 30- and 90-day mortality, respectively). CONCLUSION: Patients with resectable oesophageal cancer should be advised to choose a high-volume surgeon, but they should also be aware that differences among individual surgeons might further affect survival.
