ABSTRACT

OBJECTIVE: To examine the impact of The National Training Program for Lapco on the rate of laparoscopic surgery and clinical outcomes of cases performed by Lapco surgeons after completion of training. SUMMARY OF BACKGROUND DATA: Lapco provided competency-based supervised clinical training for specialist colorectal surgeons in England. METHODS: We compared the rate of laparoscopic surgery, mortality, and morbidity for colorectal cancer resections by Lapco delegates and non-Lapco surgeons in 3-year periods preceding and following Lapco using difference in differences analysis. The changes in the rate of post-Lapco laparoscopic surgery with the Lapco sign-off competency assessment and in-training global assessment scores were examined using risk-adjusted cumulative sum to determine their predictive clinical validity with predefined competent scores of 3 and 5 respectively. RESULTS: One hundred eight Lapco delegates performed 4586 elective colo-rectal resections pre-Lapco and 5115 post-Lapco while non-Lapco surgeons performed 72,930 matched cases. Lapco delegates had a 37.8% increase in laparoscopic surgery which was greater than non-Lapco surgeons by 20.9% [95% confidence interval (CI), 18.5-23.3, P < 0.001) with a relative decrease in 30-day mortality by -1.6% (95% CI, -3.4 to -0.2, P = 0.039) and 90-day mortality by -2.3% (95% CI, -4.3 to -0.4, P = 0.018). The change point of risk-adjusted cumulative sum was 3.12 for competency assessment tool and 4.74 for global assessment score whereas laparoscopic rate increased from 44% to 66% and 40% to 56%, respectively. CONCLUSIONS: Lapco increased the rate of laparoscopic colorectal cancer surgery and reduced mortality and morbidity in England. In-training competency assessment tools predicted clinical performance after training.

ABSTRACT

BACKGROUND: Individual trials comparing hand-sewn with stapled closure of loop ileostomy show different outcomes due to lack of statistical power. A systematic review, with a pooled analysis of results, might provide a more definitive answer. This review aimed to compare hand-sewn with stapled anastomotic technique for closure of a loop ileostomy and looked at the effect of bowel resection on the complication rates. METHODOLOGY: Relevant studies were identified from MEDLINE, EMBASE and the Cochrane database. All randomised clinical trials, prospective and retrospective studies comparing hand-sewn with stapled closure of loop ileostomy were included. RESULTS: Of the 4,917 patients in 15 identified studies, 3,406 had hand-sewn and 1,511 stapled anastomosis. There was no difference in the rate of anastomotic leak between the hand-sewn (2.93%, 55/1,877) and the stapled group (2.08%, 25/1,202) (OR 0.81, 95% CI 0.43-1.54, p = 0.52, I2 = 33%). The rate of small-bowel obstruction was higher in the hand-sewn group (7.03%, 231/3,284) compared to the stapled group (5.58%, 73/1,308; OR 0.69, 95% CI 0.51-0.92, p = 0.01, I2 = 0%). There was no difference in the incidence of anastomotic leak and small-bowel obstruction in the hand-sewn anastomosis between patients with or without bowel resection. CONCLUSIONS: There was no significant difference in the rate of anastomotic leakage between the hand-sewn and stapled techniques. The rate of small-bowel obstruction was higher in the hand-sewn group. Performance of bowel resection does not significantly increase the incidence of anastomotic leak or small-bowel obstruction.

ABSTRACT

OBJECTIVES: To develop, validate, and implement a competency assessment tool (CAT) for technical surgical performance in the context of a summative assessment process for the National Training Programme in Laparoscopic Colorectal Surgery (NTP). BACKGROUND: The NTP is an educational initiative by the National Cancer Action Team in England to safely increase the uptake of laparoscopic colorectal surgery. It is the first competency-based national educational initiative for specialist surgeons (consultants), and performance assessment is an integral part of the program. METHODS: Content validity was sought using expert opinion by semistructured interviews and the Delphi method. For validity and reliability studies, NTP apprentices and experts were asked to submit video-recorded cases. Construct validity was established between delegates who passed the assessment and those who failed. Concurrent validity was tested by comparing scores with error counts as identified by observational clinical human reliability analysis. A fully crossed design, using generalizability theory methods and D-studies, was used for reliability. FINDINGS: Interviews and the Delphi method revealed a list of characteristics for assessment. A hybrid structure combining task-specific and generic items was used to include important characteristics into the assessment format. Fifty-four cases were submitted. Overall reliability reached G(ACI) = 0.803 when using 2 cases and 2 assessors. Experts scored significantly better than apprentices (3.19 vs 2.60; P = 0.004), and apprentices who passed had better scores than those who failed (2.95 vs 2.28; P < 0.001). There was an inverse correlation between CAT scores and observational clinical human reliability analysis error counts (ρ = -0.520, P < 0.001). The combination of both methods reached overall sensitivity of 100%, specificity of 83.3%, a positive predictive value of 93.8%, and a negative predictive value of 100%. CONCLUSIONS: The CAT can reliably assess technical performance in laparoscopic colorectal surgery. The use of CATs to judge specialist technical performance before embarking on independent practice of new procedures is achievable on a national scale and can be adapted by other specialties.

ABSTRACT

BACKGROUND: Surgical trauma suppresses host immune function, potentially creating an environment vulnerable to tumor cell growth. This study compared immune function after laparoscopy, minilaparotomy, and conventional colorectal tumor resections. METHODS: Seventy-one patients underwent surgery (20 laparoscopy, 21 minilaparotomy, and 30 conventional). Blood samples were taken before surgery and at 3 hours, 24 hours, and 5 days after surgery. White blood cell constitution was determined using monoclonal antibodies. Levels of TH1 cytokines interferon-gamma, tumor necrosis factor-alpha, and interleukin (IL)-2 and TH2 cytokines IL-10, -4, and -6 were measured in plasma and from supernatants of activated peripheral blood mononuclear cells. RESULTS: At 5 days after surgery, lymphocyte counts remained low in the conventional and minilaparotomy groups (P = .001 and P = .008) but had resolved in laparoscopic patients. Three-hour postoperative serum IL-6 concentrations were lower in laparoscopic than in conventional patients (P = .028). Production of TH1 cytokines 3 hours after surgery were significantly increased in laparoscopic patients (interferon-gamma P = .018, tumor necrosis factor-alpha P = .011, and IL-2 P = .037). CONCLUSIONS: TH1 lymphocyte function is improved transiently and immune homeostasis restored earlier in patients undergoing laparoscopic colorectal cancer resection, which may influence disease recurrence.
