Characteristics of Interval Colorectal Cancer: A Canadian Retrospective Population-Level Analysis from Newfoundland and Labrador.

Interval colorectal cancers (I-CRCs) arise during the interval time period between scheduled colonoscopies. Predicting which patients are at risk of I-CRCs remains an elusive undertaking, but evidence would suggest that most I-CRCs arise from lesions missed on index endoscopy. The procedural factors that lead to missed lesions are numerous and lack consensus in the literature. In Canada, the province of Newfoundland and Labrador has the highest incidence of CRCs. In this study our aim was to examine I-CRCs (3-60 months after last colonoscopy) in NL through a population-level analysis covering 67% of the province from 2001-2018. We estimated the I-CRC rate to be up to 9.3%. Median age of I-CRC diagnosis was 67.1 years with an interval time of 2.9 years. About 57% of these tumors occurred proximal to the splenic flexure, with 53% presenting as local disease. No temporal differences were observed in interval time or tumor distribution. On univariate and multivariable logistical regression, risk of right-sided I-CRC did not correlate to the index colonoscopy indication, bowel preparation quality, size of largest polyp removed, colonoscopy completion rate, or stage at presentation. Improvements in synoptic reporting utilization and national registries are needed to identity risk factors and reduce I-CRC frequency.

Research and surgical residency: moving beyond one-and-done projects and motivating for scholarly excellence.

Among surgical residents, research is often perceived as a check-mark exercise. Focus then turns to studying for exams and honing skills for independent practice. While some residents are passionate about research and enroll in other formalized training, pragmatists argue that not every surgeon should engage in research at this level. However, no resident should view research as a one-and-done activity. Rather, research should be viewed as an exercise to improve practice, share gaps in knowledge, collaborate, and empower others to formally study and implement change. The skills acquired during research experiences, at minimum, have value in improving the trainee's literature literacy, which in turn serves as a foundational element of continuing medical education. A culture supportive of scientific discovery, facilitated by both faculty and peer-to-peer mentorship, will result in better collaborative efforts and lead to improved knowledge generation and resident research satisfaction.

Advanced laparoscopic training and outcomes in laparoscopic cholecystectomy.

BACKGROUND: Advanced laparoscopic training is becoming a valuable asset for surgeons as more procedures are carried out in a minimally invasive fashion. The purpose of our study was to determine whether laparoscopic fellowship training affects outcomes in patients undergoing laparoscopic cholecystectomy for acute cholecystitis. METHODS: We obtained data from a retrospective review of 110 patients with acute cholecystitis who underwent laparoscopic cholecystectomy on an urgent basis from March 2002 to June 2005. We compared the outcomes of 31 patients whose surgeries were performed by a surgeon with advanced laparoscopic training with those of 79 patients whose surgeries were performed by surgeons without such training. RESULTS: The 2 groups were similar in terms of demographics and time to surgery. Outcome measures included conversion rates, postoperative length of stay (LOS) and complications. There was a significant difference in conversion rates (3.2 % v. 16.5 %, p = 0.050) and postoperative LOS (1.77 v. 2.82 d, p < 0.006) between the 2 groups, but there was no difference in the rate of postoperative complications. There was no significant difference in conversion rates among the surgeons without advanced training (p = 0.64). CONCLUSION: Based on our results, laparoscopic cholecystectomy in acute cholecystitis is associated with improved outcomes when performed by a surgeon with fellowship training in laparoscopic surgery.

Use of human patient simulation and the situation awareness global assessment technique in practical trauma skills assessment.

BACKGROUND: Situation awareness (SA) is defined as the perception of elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future. This construct is vital to decision making in intense, dynamic environments. It has been used in aviation as it relates to pilot performance, but has not been applied to medical education. The most widely used objective tool for measuring trainee SA is the Situation Awareness Global Assessment Technique (SAGAT). The purpose of this study was to design and validate SAGAT for assessment of practical trauma skills, and to compare SAGAT results to traditional checklist style scoring. METHODS: Using the Human Patient Simulator, we designed SAGAT for practical trauma skills assessment based on Advanced Trauma Life Support objectives. Sixteen subjects (four staff surgeons, four senior residents, four junior residents, and four medical students) participated in three scenarios each. They were assessed using SAGAT and traditional checklist assessment. A questionnaire was used to assess possible confounding factors in attaining SA and overall trainee satisfaction. RESULTS: SAGAT was found to show significant difference (analysis of variance; p < 0.001) in scores based on level of training lending statistical support to construct validity. SAGAT was likewise found to display reliability (Cronbach's alpha 0.767), and significant scoring correlation with traditional checklist performance measures (Pearson's coefficient 0.806). The questionnaire revealed no confounding factors and universal satisfaction with the human patient simulator and SAGAT. CONCLUSIONS: SAGAT is a valid, reliable assessment tool for trauma trainees in the dynamic clinical environment created by human patient simulation. Information provided by SAGAT could provide specific feedback, direct individualized teaching, and support curriculum change. Introduction of SAGAT could improve the current assessment model for practical trauma education.

Minimally invasive surgical practice: a survey of general surgeons in Ontario.

INTRODUCTION: With the rapidly evolving techniques for minimally invasive surgery (MIS), general surgeons are challenged to incorporate advanced procedures into their practices. We therefore carried out a study to assess the state of MIS practice in Ontario. METHODS: A questionnaire was mailed to 390 general surgeons in Ontario. It addressed the surgeon's practice demographics, performance of both basic and advanced MIS procedures, the factors influencing this practice and the means of obtaining MIS training. RESULTS: Of the 390 general surgeons surveyed, 309 (79%) responded. Thirty-six of these were retired and were excluded from the analysis, leaving 273 available for study. The average age in the study group was 49.7 years; 247 (90%) were men. Of 272 who responded to the question, 116 (43%) had subspecialty training. The average surgeon's operating room (OR) time was 1.5 d/wk and the average waiting time for elective procedures was 4 weeks. We found that 257 (94%) respondents performed basic laparoscopic procedures, and 164 (60%) performed appendectomy; 135 (49%) performed at least 1 advanced laparoscopic procedure in their practice, although only 30 (22%) of these performed inguinal hernia repair. Using a Likert scale, we found that the most important factors influencing the incorporation of advanced laparoscopic procedures into surgical practice were a lack of OR time (median 4), lack of OR financial resources (median 4) and lack of training opportunities (median 4). Of surgeons responding to questions, 161 (64%) of 251 felt that the present medical environment did not allow them to meet standard-of-care requirements; they felt that it was the responsibility of academic surgical departments (214 [80%] of 268), the Canadian Association of General Surgeons (177 [68%] of 262) and the Ontario Association of General Surgeons (141 [53%] of 264) to provide continuing medical education courses for MIS training. CONCLUSION: The ability of practising general surgeons to incorporate advanced MIS procedures into their surgical practice remains a complex issue.

Minimally invasive adrenalectomy for pheochromocytoma during pregnancy.

Pheochromocytoma during pregnancy is a very rare condition; fewer than 200 cases have been reported in the literature. We present the case of a 24-year-old pregnant woman found to have a pheochromocytoma during investigation of abdominal pain. This is the second reported case of laparoscopic adrenalectomy for pheochromocytoma detected during pregnancy. After appropriate radiologic investigation and medical management, a laparoscopic left adrenalectomy was performed at the beginning of the second trimester. There were no complications, and she was delivered of a healthy baby at term. We review the management of pheochromocytoma in pregnant patients and discuss the role of laparoscopy.
