Are surgeons aware of the dangers of diathermy?

Surgical diathermy is an invaluable aid in modern surgery and most contemporary diathermy machines are considered safe. However, diathermy accidents still do occur and a diathermy unit can be potentially lethal if adequate care is not exercised in its use.     

Colorectal surgeons’ learning curve of transanal endoscopic microsurgery

Background

Transanal endoscopic microsurgery (TEM) is a technically demanding key technique in minimally invasive rectal surgery. We investigated the learning curve of colorectal surgeons commencing with TEM.

Methods

All TEM procedures of four colorectal surgeons were analyzed. Procedures were ranked chronologically per surgeon. Outcomes included conversion, postoperative complications, procedure time, and recurrence. Backward multivariable regression analysis identified learning curve effects and other predictors.

Results

Four surgeons resected 693 rectal lesions [69.9 % adenoma/25.5 % carcinoma; median size 20 cm²; interquartile range (IQR) 11–35; 7 ± 4 cm ab ano]. A total of 555 resections (80.1 %) were histopathologically radical (R0). Conversion (4.3 %) was influenced by a learning curve [odds ratio (OR) 0.991 per additional procedure; 95 % confidence interval (CI) 0.984–0.998] and by lesion size. Postoperative complications depended only on the individual surgeon and lesion size in benign lesions (10.4 % complications). A learning curve (OR 0.99; 95 % CI 0.988–0.998) and peritoneal entrance affected complications in malignant lesions (13.3 %). Procedure time [median 55 min (IQR 30–90)] was influenced by a learning curve [B ?0.11 (95 % CI ?0.14 to ?0.09)], individual surgeon, single-piece resection, peritoneal entrance, lesion size, and rectal quadrant. Recurrence of benign lesions (4.5 %) depended on lesion size, R0 resection, and prior resection attempts. Recurrence of malignant lesions (8.9 %) depended on 3D stereoscopic view, lesion size, full-thickness resection, and length of follow-up. Recurrence-free survival of patients operated during the 36th through 80th procedure per surgeon was significantly shorter than in patients operated during procedures 1–35 and 81 onwards.

Conclusions

A surgical learning curve affected conversion rate, procedure time, and complication rate. It did not influence recurrence rates, possibly due to evolving patient populations. This first insight into the learning curve of TEM stresses the importance of quality monitoring and centralisation of care.     

Does peer-reviewed publication change the habits of surgeons?

BACKGROUND: From April 1994 to December 1995 a prospective randomized trial was conducted at our institution comparing outcomes of laparoscopic and open appendectomy. It demonstrated no significant advantage to laparoscopic appendectomy. Our current study evaluates whether surgeon's habits at our hospital have been influenced by our previously published study. METHODS: Charts were reviewed for patients who underwent appendectomy from August 1998 to December 1998. In addition, a formal survey was conducted of all staff surgeons to ascertain their procedure of choice for appendicitis, and the reasons for their preference. RESULTS: Seventy-nine percent of the appendectomies were attempted laparoscopically. The median operative time was longer for laparoscopic appendectomy, and median hospital charges were higher. Survey results showed that most staff surgeons prefer laparoscopic appendectomy. CONCLUSION: Despite our own published paper supporting open appendectomy over laparoscopic appendectomy, laparoscopic appendectomy has become the standard of care at our institution for the treatment of appendicitis.     

A survey of surgeons’ perception and awareness of intraoperative time utilization

Background

Surgical teams’ awareness of the time needed to perform specific phases of a surgical procedure is likely to improve communication in the operating theatre and benefit patient safety. The aim of this study was to assess surgeons’ awareness of time utilization and the actual time needed to perform specific phases of an operation.

Methods

A survey was conducted to examine the method and design for a larger study. Interviews were conducted with 18 surgeons, and surgical time was measured during 21 colon cancer resections. Correlation analyses were performed to explore the factors that might affect operating time.

Results

The surgical phase with the greatest variation in time was dissection/resection (43–308 minutes). On a group level, no statistically significant differences were found between estimated and measured surgical procedural times for partial or full resections (160.4 versus 173.0 minutes, p?=?0.539). However, interindividual variation was substantial. There was a positive significant correlation between long duration of dissection/resection and longer time to close the abdomen (r?=?0.464, p?=?0.039), as well as between long duration of a hand-sewn anastomosis and time needed to close the abdomen (r?=?0.536, p?=?0.018).

Conclusions

It can be difficult for a single surgeon to estimate the time required for a partial or full surgical procedure. A larger study might provide additional time estimates and identify variables that affect surgical time. The data could be of interest in the planning and scheduling of surgical resources, thus improving theatre team communication and patient safety.

     

Do orthopaedic surgeons need a policy on the removal of metalwork? A descriptive national survey of practicing surgeons in the United Kingdom

INTRODUCTION: Routine metalwork removal, in asymptomatic patients, remains a controversial issue. Current literature emphasises the potential hazards of implant removal and the financial implications encountered from these procedures. However, there is little literature guidance and no published research on current practice. AIM: To estimate the current state of practice of orthopaedic surgeons in the United Kingdom regarding implant removal in asymptomatic patients. METHODS: An analysis, by two independent observers, was performed on the postal questionnaire replies of 36% (500 out of 1390), randomly selected UK orthopaedic consultants. RESULTS: Four hundred and seven (81%) replies were received. A total of 345 (69%) were found to be suitable for analysis. The most significant results of our study (I) 92% of orthopaedic surgeons stated that they do not routinely remove metalwork in asymptomatic skeletally mature patients; (II) 60% of trauma surgeons stated that they do routinely remove metalwork in patients aged 16 years and under; (III) 87% of the practicing surgeons indicated that they believe it is reasonable to leave metalwork in for 10 years or more; (IV) only 7% of practicing trauma surgeons who replied to this questionnaire have departmental or unit policy. CONCLUSION: Our results demonstrate that most practicing trauma surgeons do comply with the evidence presented in the little literature available. However, we do believe that a general policy for metalwork removal is essential. Such a policy should include guidelines specific to age groups and level of surgeon who should be performing the removal procedure. Such a document would require further validated studies but would eventually serve to steer surgeons in achieving best practice.     

What do master surgeons think of surgical competence and revalidation?

BACKGROUND: There has been on-going debate and public interest in surgical competence in recent years. METHODS: A Delphi reiterative opinion survey was conducted among master surgeons on selection of surgical trainees, methods of assessment of progress of surgical trainees, and revalidation of established consultant surgeons. RESULTS: Selection-the current methods of trainee selection were considered inadequate and in need of revision. The important attributes recognized by group are cognitive factors, innate dexterity, and personality. Important aspects of personality include decision-making ability, insight, team spirit, and emotional stability. Assessment during training-the majority view was that this should be based on clinical judgement/skills, operative skills, and cognitive ability. Assessment of technical ability should be based on standardized checklists. Research within training programs was encouraged but academic achievement does not reflect surgical competence. There was a majority verdict for an exit clinical examination. Revalidation-the group agreed on the need for competence checks during the professional career of surgeons. These should cover knowledge, clinical, operative, and humanistic skills; but expressed concern on the feasibility of a revalidation system that can reliably assess the range of skills needed for surgical competence. There was a majority vote against an internal appraisal system. External assessment by nationally appointed 'assessors' was considered preferable. CONCLUSIONS: Both selection and assessment of surgical trainees require changes and standardization. Although revalidation is necessary, concern was expressed on the reliability and validity of existing and proposed systems.     

How can we build mentorship in surgeons of the future?

Background: In the past, surgical training has been based on traditional apprenticeship model of mentoring. To cope with the rapidly changing environment of modern surgery, the mentoring process may require significant modernization. Methods: Literature for this review was identified by searching for the MeSH heading ‘mentors’ in Ovid MEDLINE, EMBASE, PsycINFO and Cochrane Library databases (1950 to September 2010). The literature was reviewed to specifically identify challenges of mentoring future surgeons and to delineate a framework to establish a mentor–mentee relationship by means of a formal mentoring scheme. Results: Multidimensional approaches, models and methods of delivering mentoring are essential to meet the challenges of modern surgery. We advocate a 10‐stage approach to implement a formal mentoring scheme at local, national and international levels. Conclusion: Formalizing the mentoring process, with local, national and international schemes, will initiate mentoring relationships and cultivate a mentoring culture. Ultimately, this will maintain and improve patient care.     

Factors influencing surgeons’ choice of method for hernia repair technique

Tension-free hernioplasty is performed using prosthetic material in one-half of hernia repair procedures in Poland but in 85% of those in the region of Pomerania. This questionnaire study of surgeons in Pomerania examined their sources of knowledge about and the factors influencing their choice of groin hernia surgery. The questionnaire was sent to surgeons from 19 hospitals and was answered by 109 (83% of hernia surgeons in the region). We analyzed their reported knowledge of particular operative techniques, factors important in selecting the technique (personal experience, trends in surgical center), and the available sources of information (e.g., medical literature, internet, information from teachers, sales representatives). All respondents reported being familiar with and able to perform tension-free techniques, but only 44% are influenced by their individual professional skills in selecting the technique. Another 44% base their decision on trends in their hospital, and only 22% consider the patients preferences. The most frequently quoted sources of scientific information are articles in the medical literature and conference reports (90%). Only 8% of the respondents are governed in their professional work by information from pharmaceutical company representatives. Most surgeons (70%) would prefer to make a decision about using a new surgical technique after practical training sessions or workshops led by experienced colleagues. In contrast to common opinion, the information from sales representatives are of only minor importance compared to that of evidence-based data and attendance at workshops and courses.     

Analysis of eye gaze: Do novice surgeons look at the same location as expert surgeons during a laparoscopic operation?

Introduction

Eye-gaze technology can be used to track the gaze of surgeons on the surgical monitor. We examine the gaze of surgeons performing a task in the operating room and later watching the operative video in a lab. We also examined gaze of video watching by surgical residents.

Methods

Data collection required two phases. Phase 1 involved recording the real-time eye gaze of expert surgeons while they were performing laparoscopic procedures in the operating room. The videos were used for phase 2. Phase 2 involved showing the recorded videos to the same expert surgeons, and while they were watching the videos (self-watching), their eye gaze was recorded. Junior residents (PGY 1-3) also were asked to watch the videos (other-watching) and their eye gaze was recorded. Dual eye-gaze similarity in self-watching was computed by the level of gaze overlay and compared with other-watching.

Results

Sixteen cases of laparoscopic cholecystectomy were recorded in the operating room. When experts watched the videos, there was a 55?% overlap of eye gaze; yet when novices watched, only a 43.8?% overlap (p?<?0.001) was shown.

Conclusions

These findings show that there is a significant difference in gaze patterns between novice and expert surgeons while watching surgical videos. Expert gaze recording from the operating room can be used to make teaching videos for gaze training to expedite learning curves of novice surgeons.     

Hip fracture surgery in Nova Scotia: a comparison of treatment provided by “generalist” general surgeons and orthopedic surgeons

Objective

To determine quality of hip fracture services provided by “generalist” general surgeons (generalists) in Nova Scotia.

Design

Chart review and postoperative, blinded, random-ordered radiologic analysis.

Setting

Three community hospitals and 1 tertiary care hospital in Nova Scotia.

Participants

Seven generalists who performed 120 hip fracture repairs and 7 orthopedic surgeons (specialists) who performed 135 hip fracture repairs.

Outcome measures

Patient demographics, preoperative, perioperative, postoperative and discharge information, technical quality of reduction as determined through postoperative radiologic assessment.

Results

There were no differences between patients treated by generalists and those treated by specialists with respect to age, sex, American Society of Anesthesiologists’ class, level of function and fracture type. Intraoperatively, the patient groups were similar with respect to type of anesthesia, use of antibiotics, number of transfusions and surgical complications. Significant differences were noted in length of operation (54.4 v. 41.1 minutes), use of C-arm imaging (6.7% v. 85.9%) and management of Garden classes 1 and 2 subcapital fractures. Postoperatively, the 2 groups had similar numbers of medical complications, wound complications, reoperations, readmissions and deaths, and a similar level of function on discharge. Significant differences included the number of intensive care unit admissions (5.8% v. 15.6%) and length of stay there (5.7 v. 2.8 days) and of postoperative stay (14.5 v. 10.7 days). The assessment of radiographs did not demonstrate any significant difference in the quality of reduction.

Conclusion

In Nova Scotia the outcomes of hip fracture surgery performed by generalists are comparable to those performed by specialists.     

Survey of hand surgeons’ and therapists’ perceptions of the benefit of common surgical procedures of the hand

Objective: The objectives of this survey were (1) to study if surgeons’ perceptions of the benefit of six surgical procedures differ if they consider themselves as patients instead of treating a patient, (2) to evaluate the role of five predetermined factors that may influence decision-making, and (3) to assess how uniformly hand surgeons and hand therapists perceive the benefits of the surgical treatments.

Methods: The members of the national societies for Hand Surgery and Hand Therapy were asked to participate in the survey. Six patient cases with hand complaint (carpal tunnel syndrome, flexor tendon injury, dorsal wrist ganglion, thumb amputation, boxer’s fracture, and mallet fracture) and a proposed operative procedure were presented, and the respondents rated the procedures in terms of the expected benefit. Half of the surgeons were advised to consider themselves as patients when filling out the survey.

Results: A survey was completed by 56 surgeons (61%) and 59 therapists (20%). Surgeons who considered themselves as patients had less confident perception on the benefit of carpal tunnel release compared with surgeons, who considered treating patients. Hand surgeons and hand therapists had similar perception of the benefits of surgery. The expected functional result was regarded as the most important factor in directing the decision about the treatment.

Conclusions: Surgeons tended to be more unanimous in their opinions in cases, where there is limited evidence on treatment effect. The agreement between surgeons and therapists implies that the clinical perspectives are similar, and probably reflect the reality well.     

Impact of AITS laparoscopic training center on surgeons’ preference for appendectomy

Background  

Acute appendicitis is the most common acute abdomen in general surgery. Show-Chwan Memorial Hospital began an AITS/IRCAD laparoscopic training program in late May 2008. In this retrospective analysis, we surveyed the impact of the AITS training program on surgeons’ preference for open appendectomy (OA) versus laparoscopic appendectomy (LA).
