A unique approach to quantifying the changing workload and case mix in laparoscopic colorectal surgery

Value of multi-disciplinary input into laparoscopic management of rectal cancer - An observational study

AIM

To assess the impact of multi-disciplinary teams (MDTs) management in optimising the outcome for rectal cancers.

METHODS

We undertook a retrospective review of a prospectively maintained database of patients with rectal cancers (defined as tumours ≤ 15 cm from anal verge) discussed at our MDT between Jan 2008 and Jan 2011. The data was validated against the national database to ensure completeness of dataset. The clinical course and follow-up data was validated using the institution’s electronic patient records. The data was analysed in terms of frequencies and percentages. Significance of any differences were analysed using χ² test. A Kaplan-Meier analysis was performed for overall survival and disease free survival.

RESULTS

Following appropriate staging, one hundred and thirty-three patients were suitable for potentially curative resections. Seventy two (54%) were upper rectal cancer (URC) - tumour was > 6 cm from the anal verge and 61 (46%) were lower rectal cancers (LRC) - lower extent of the tumour was palpable ≤ 6 cm. Circumferential resection margin (CRM) appeared threatened on pre-operative MRI in 19/61 (31%) patients with LRC requiring neo-adjuvant therapy (NAT). Of the 133 resections, 118 (89%) were attempted laparoscopically (5% conversion rate). CRM was positive in 9 (6.7%) patients; Median lymph node harvest was 12 (2-37). Major complications occurred in 8 (6%) patients. Median follow-up was 53 mo (0-82). The 90-d mortality was 2 (1.5%). Over the follow-up period, disease related mortality was 11 (8.2%) and overall mortality was 39 (29.3%). Four (3%) patients had local recurrence and 22 (16.5%) patients had distant metastases.

CONCLUSION

Management of rectal cancers can be optimized with multi-disciplinary input to attain acceptable long-term oncological outcomes even when incorporating a laparoscopic approach to rectal cancer resection.

A structured preceptorship programme for laparoscopic colorectal surgery in Wales: An early experience

INTRODUCTION

A single experienced laparoscopic colorectal surgeon introduced an outreach preceptorship programme (OPP) for laparoscopic colorectal surgery (LCS) in Wales with the aim of supporting consultants in the early stages of their learning curve, as well as to help avoid some of the problems faced by self-taught laparoscopic surgeons. The structured programme consisted of a minimum 1 day master class at the preceptor's operating theatre, followed by multiple outreach visits by the preceptor. The aim of this study was to evaluate the effectiveness and early experience of this programme.

MATERIALS AND METHODS

Clinical end-points (conversions, morbidity/mortality and length of hospital stay) were analysed from a prospectively maintained database. Evaluation of the programme was based on interviews with the preceptee surgeons performed by a neutral observer.

RESULTS

Between May 2008 and July 2010, 11 Consultants (six hospitals) were preceptored (two still in programme). 66 cases (20 in the master class, 46 as an outreach service) were performed as a part of this programme.

CLINICAL OUTCOME

Conversion rate and 30-day mortality was 1.5%. Morbidity was reported at 12% (8/66) and median length of stay was 6 days. Programme evaluation: All interviewed respondents found the master class and outreach service to be well-organised and would recommend it to their colleagues. The median number of outreach visits per hospital was 5. All the preceptees have performed independent cases since the programme.

CONCLUSION

This OPP delivers one-to-one coaching at the point of service delivery and has been shown to be effective in achieving safe transference of skills to those wishing to develop a service for LCS.

Does case selection and outcome following laparoscopic colorectal resection change after initial learning curve? Analysis of 235 consecutive elective laparoscopic colorectal resections

INTRODUCTION:

Laparoscopic colorectal surgery is being widely practiced with an excellent short-term and equal long-term results for colorectal diseases including cancer. However, it is widely believed that as the experience of the surgeon/unit improves the results get better. This study aims to assess the pattern of case selection and short-term results of laparoscopic colorectal surgery in a high volume centre in two different time frames.

MATERIALS AND METHODS:

This study was done from the prospective data of 265 elective laparoscopic colorectal resections performed in a single unit from December 2005 to April 2011. The group was subdivided into initial 132 patients (Group 1) from December 2005 to December 2008 and next 133 patients (Group 2) between December 2008 and April 2011 who underwent laparoscopic colorectal resections for cancer. The groups were compared for intraoperative and perioperative parameters, type of surgery, and the stage of the disease.

RESULTS:

The age of patients was similar in Groups 1 and 2 (57.7 and 56.9, respectively). Patients with co-morbid illness were significantly more in Group 2 than in Group 1 (63.2% vs. 32.5%, respectively, P≤0.001). There were significantly more cases of right colonic cancers in Group 1 than in Group 2 (21.9% vs. 11.3%, respectively, P<0.02) and less number of low rectal lesions (20.4% vs. 33.8%, respectively, P≤0.02). The conversion rates were 3.7% and 2.2% in Groups 1 and 2, respectively. The operating time and blood loss were significantly more in Group 1 than in Group 2. The ICU stay was significantly different in Groups 1 and 2 (31.2± 19.1 vs. 24.7± 18.7 h, P≤0.005). The time for removal of the nasogastric tube was significantly earlier (P=0.005) in Group 2 compared to Group 1 (1.37± 1.1 vs. 2.63±1.01 days). The time to pass first flatus, resumption of oral liquids, semisolid diet, and complications were similar in both groups. The hospital stay was more in Group 1 than in Group 2 ( P≤0.01). The numbers of lymph nodes retrieved was similar in both groups. The T stage of the disease in Groups 1 and 2 were similar, however, the number of T4 lesions was significantly more in Group 2 (8.3% vs. 18.7%, respectively, P<0.01).

CONCLUSION:

This study shows that with increasing experience, laparoscopic colorectal surgery can be practiced safely with minimal conversion rates and morbidity. As the units experience improves, there is a trend towards selecting advanced cases and performing complex laparoscopic colorectal procedures. With increasing experience, there is a trend towards better short-term outcome after laparoscopic colorectal surgeries.

A tool-kit for the quantitative assessment of proficiency in laparoscopic colorectal surgery

AIM

Laparoscopic colorectal surgery includes operative procedures of varying complexity, and traditional assessment tools may not be enough to assess competence. This study defines quantitative tools for assessing proficiency in laparoscopic colorectal surgery.

METHOD

A single surgeon's 11-year experience was subdivided into five phases with equal numbers of patients. A tool-kit, with specific tools defined as the complexity score, the conversion score, the technical score, the training score and the proficiency score, has been developed and used to evaluate each phase of the experience.

RESULTS

There were 400 patients, with 80 in each of the five phases. The complexity score increased from 23.75 to 63.75 over the five phases. Similar increases were also demonstrable in the conversion score (from 0.45 to 15.45), the technical score (from 30 to 96.5), the training score (from 5.8 to 34.8) and the overall proficiency score (from 15 to 52.63).

CONCLUSION

The results show that it is possible to quantify the workload in laparoscopic colorectal surgery and to assess increasing proficiency using a simple, reproducible and reliable tool-kit.
