Spiral saphenous vein graft for major pelvic vessel reconstruction during exenteration surgery.

This article describes a great saphenous vein spiral graft technique for reconstruction of iliac vessels after en bloc resection during pelvic exenteration. Use of different size syringes as a scaffold allows the surgeon to construct autologous vascular interposition conduits of variable diameter to match the luminal size of the vessel requiring reconstruction. Autologous vascular grafts are preferred in exenteration surgery in which the operative field is commonly contaminated by concomitant bowel resection, which carries an increased risk of graft infection.

Barriers to the uptake of laparoscopic surgery in a lower-middle-income country.

BACKGROUND: Despite the significant improvements in surgical care in developed countries, the adoption of laparoscopy in lower-middle-income countries (LMICs) has been sporadic and minimal. Although the most quoted explanation for this has been an apparent lack of resources and training, recent studies have demonstrated that these constraints may not be the only significant barrier. The overall aim of this study was to analyze barriers to the adoption of laparoscopic surgery at a hospital in an LMIC. METHODS: Using an exploratory case study design, this investigation identified barriers to the adoption of laparoscopic surgery in an LMIC. More than 600 hours of participant observation as well as 13 in-depth interviews and document analyses were collected over a 12-week period. RESULTS: Three overarching barriers emerged from the data: (1) the organizational structure for funding laparoscopic procedures, (2) the hierarchical nature of the local surgical culture, and (3) the expertise and skills associated with a change in practice. The description of the first barrier shows how the ongoing funding structure, rather than upfront costs, of the laparoscopic program limited the number of laparoscopic cases. The description of the second barrier highlights the importance of understanding the local surgical culture in attempts to adopt new technology. The description of the third barrier emphasizes the fact that due to the generalist nature of surgical practice, surgeons were less willing to practice more technically complicated and time-consuming procedures. CONCLUSION: This exploratory case study examining the barriers hindering the adoption of laparoscopy in an LMIC represents a novel approach to addressing issues that have plagued surgeons across LMICs for many years. These findings not only further understanding of how to improve the adoption of laparoscopy in LMICs but also challenge the economic-centric notions of the problems that affect the transfer of innovation across social, economic, and geographic boundaries.

Remote evaluation of laparoscopic performance using the global operative assessment of laparoscopic skills.

BACKGROUND: Although numerous assessment tools currently exist to evaluate laparoscopic surgical skills, no studies have demonstrated the reliability of such tools when used with telementoring technology. This study aimed to determine the reliability of the Global Operative Assessment of Laparoscopic Skills (GOALS) rating scale for assessing laparoscopic skills remotely and to identify how factors unique to remote assessment such as bandwidth and image quality influence its reliability. METHODS: Four trained observers evaluated 19 participants for their technical performance during a laparoscopic cholecystectomy using the GOALS assessment tool. One observer assessed the study participants directly in the operating room, whereas the three remaining observers were randomly assigned and blinded to a high- (1.5 Mbps), medium- (256 kbps), or low- (64.4 kbps) bandwidth restriction and observed remotely via Skype. The Maryland Visual Comfort Scale was used to evaluate the video quality of the respective connections. RESULTS: The intraclass correlation coefficient (ICC) calculated for the total GOALS score demonstrated a statistically significant correlation of high, medium, and low bandwidths respectively with ICC 0.693 (95 % confidence interval [CI], 0.226-0.883), 0.518 (95 % CI 0.089-0.783), and 0.499 (95 % CI 0.025-0.781). There was a statistically significant difference in the overall perceived visual quality between the high/low (Z = -3.222; P = 0.001) and the medium/low (Z = -3.567; P < 0.001) bandwidth comparison but no difference between the high/medium bandwidths (Z = -0.610; P = 0.542). CONCLUSION: The data suggest that the GOALS assessment tool retains its reliability for intraoperative assessment of laparoscopic skills when used remotely. This is a key requirement in telesimulation programs allowing for structured feedback between the mentor and the mentee. This study quantifies the effect that bandwidth has on the reliability of remote assessment, demonstrating that higher bandwidths improve the utility of these tools.

Evaluation of surgical performance during laparoscopic incisional hernia repair: a multicenter study.

BACKGROUND: Laparoscopic incisional hernia repair (LIHR) is a common procedure requiring advanced laparoscopic skills. This study aimed to develop a procedure-specific tool to assess the performance of LIHR and to evaluate its reliability and validity. METHODS: The Global Operative Assessment of Laparoscopic Skills-Incisional Hernia (GOALS-IH) is a 7-item global rating scale developed by experts to evaluate the steps of LIHR (placement of trocars, adhesiolysis, estimation of mesh size and shape, mesh orientation and positioning, mesh fixation, knowledge and autonomy in use of instruments, overall competence), each rated on a 5-point Likert scale. During LIHR, 13 attending surgeons and fellows experienced in minimally invasive surgery (MIS) and 19 novice surgeons (postgraduate years [PGYs], 3-5) were evaluated at four teaching hospitals by the attending surgeon, a trained observer, and self-assessment using GOALS-IH, and by a previously validated 5-item general laparoscopic rating scale (GOALS). Interrater reliability was assessed by intraclass correlation (ICC), and internal consistency of rating items was assessed by Cronbach's alpha. Known-groups construct validity was assessed by using the t-test and by correlating of the number of self-reported LIHR cases with the total score. Concurrent validity was assessed by correlating the GOALS-IH score with the GOALS general rating scale. Data are presented as mean and 95% confidence interval (CI). RESULTS: Interrater reliability for the total GOALS-IH score was 0.79 (95% CI, 0.60-0.89) between observers and attending surgeons, 0.81 (95% CI, 0.58-0.92) between participants and attending surgeons, and 0.89 (95% CI, 0.76-0.96) between participants and observers. Internal consistency was high (Cronbach's alpha, 0.93). Experienced surgeons performed significantly better than novices as assessed by GOALS-IH (31; 95% CI, 29-33 vs. 21; 95% CI, 19-24; p < 0.01). Very good correlation was found between GOALS-IH and previous LIHR experience (r = 0.82; p < 0.01) and strong correlation between GOALS-IH and generic GOALS total scores (r = 0.90; p < 0.01). CONCLUSION: Surgical performance during clinical LIHR can be assessed reliably using GOALS-IH. Results can be used to provide formative feedback to the surgeon and to identify steps of the operation that would benefit from specific educational interventions.

Incidental detection of colorectal lesions by FDG PET/CT scans in melanoma patients.

BACKGROUND: Increased use of PET/CT scans in oncology patients has raised detection of Colorectal incidentalomas (CIs). The frequency and diagnostic outcomes of identifying these lesions in melanoma patients have not previously been studied. This studies primary objective was to determine the prevalence of CIs found on PET/CT scans in melanoma patients. The secondary objectives were to correlate the PET/CT findings with the pathology found at colonoscopy, and identify which patients were referred for colonoscopy. METHODS: A retrospective analysis of patients identified from the prospectively collected research database of Melanoma Institute Australia. 2509 patients with melanoma underwent PET/CT scans between 2001 and 2013. The prevalence of CIs, the correlation of lesions, and the survival of patients who underwent colonoscopy versus patients who did not were analyzed. RESULTS: The prevalence of CIs in melanoma patients who had PET/CT scans was 3.2%. Forty-five of the 81 (56%) patients with CIs underwent colonoscopy. Of these, premalignant or malignant disease was found in 58%. Patients with previous metastatic melanoma were significantly less likely to be referred for colonoscopy. Patients undergoing colonoscopy had significantly better survival, as did those without previous distant metastases before the CIs were found, and those without any metastases at the time the CIs were found. These factors were not significant on multivariate analysis. CONCLUSION: The prevalence of incidental colorectal lesions identified on PET/CT scans in melanoma patients was found to be equivalent to that in the general cancer population. Patients undergoing colonoscopy had better survival than those who did not.

Baseline quality of life predicts pelvic exenteration outcome.

BACKGROUND: Recurrent rectal cancer affects a significant group of patients with no current consensus on management. This study investigated patients' quality of life (QoL) in the 12 months after pelvic exenteration. METHOD: Prospective cohort study with clinical and QoL data collected at baseline and 1, 3, 6, 9 and 12 months. QoL trajectories were modelled over 12 months from date of discharge using linear mixed models. RESULTS: Of 117 patients, 93 underwent pelvic exenteration surgery, 24 did not. Thirty-day mortality was nil for both groups. For patients who had surgery, 15 (16%) died within 12 months of surgery compared with nine (38%) of the non-surgery group. Baseline QoL scores were highly variable. The non-exenteration patients' QoL gradually declined over 12 months while exenteration patients declined then recovered. Patients with high baseline QoL scores remained high, and those with low baseline QoL remained low. Baseline QoL score, gender and bony resection were significant predictors of QoL score at 12 months. CONCLUSION: Baseline QoL is a significant, independent predictor of patients' QoL after pelvic exenteration for recurrent rectal cancer.

Simulation in surgery: perfecting the practice.

The apprenticeship model that surgical training has traditionally relied on has proven to be an expensive, time-consuming, and inconsistent model for producing skilled surgeons. Combined with increased public scrutiny on patient safety, financial concerns, restricted work hours, and expanding skill requirements, it has become clear that a new pedagogic paradigm is required. This article reviews the evidence supporting the need and justification of simulation in surgical education and explores the existing and potential roles of simulation in the training and evaluation of future surgeons.

Gastrectomy and esophagogastrectomy for proximal and distal gastric lesions: a comparison of open and laparoscopic procedures.

Laparoscopic gastrectomy is safe for benign lesions; however, such surgery for cancer remains controversial. The aim of this study is to compare outcomes in open versus laparoscopic gastrectomy. Data on patients undergoing open (n = 15) or laparoscopic (n = 52) gastrectomy revealed a mean age of 61.7 and 70.5 years, respectively (P = .06). Mean operative time was 32.3 minutes longer in the laparoscopic group (P = .24). The difference in median length of hospital stay was 3 days (open 12 days, laparoscopic 9 days). Postoperative morbidity (< 30 days) was not different; however, there were more early respiratory complications in the open group (P = .009). There were 4/6 (66.7%) open and 2/29 (6.9%) cancer recurrences. Laparoscopic approach for treatment of gastric lesions is safe and does not have a deleterious effect on cancer-related outcome.
