Public perception of common cancer misconceptions: A nationwide cross-sectional survey and analysis of over 3500 participants in Saudi Arabia.

Purpose/Background: Patients and healthcare providers use online health information and social media (SM) platforms to seek medical information. As the incidence of cancer rises, the popularity of SM platforms has yielded widespread dissemination of incorrect or misleading information about it. In this study, we aimed to assess public knowledge about incorrect cancer information and how they perceive such information in Saudi Arabia. Methods: A nationwide survey was distributed in Saudi Arabia. The survey included questions on demographics, SM platform usage, and common misleading and incorrect cancer information. Results: The sample (N = 3509, mean age 28.7 years) consisted of 70% females and 92.6% Saudi nationals. Most participants had no chronic illness. One-third were college graduates and less than one-quarter were unemployed. Conclusions: Differences in level of knowledge about cancer emerged in association with different demographic factors. Public trust in health information on SM also led to being misinformed about cancer, independent from educational level and other factors. Efforts should be made to rapidly correct this misinformation.

Histopathological Patterns and Outcomes of Triple-Positive Versus Triple-Negative Breast Cancer: A Retrospective Study at a Tertiary Cancer Center.

Background One of the leading causes of cancer-related deaths in females under 45 years old is breast cancer (BC). The definition of triple-negative breast cancer (TNBC) is the lack of expression of estrogen receptors (ERs) as well as progesterone receptors (PRs) and Erb-B2 receptor tyrosine kinase 2 (HER2) gene amplification. Triple-positive breast cancer (TPBC), on the other hand, is defined as tumors expressing a high level of ER, PR, and HER2 receptors. This study aims to assess the phenotypes of TNBC and TPBC by comparing their individual clinical behavior patterns and prognosis throughout the course of the disease in a tertiary cancer center in the Kingdom of Saudi Arabia (KSA). Methods Our study is a retrospective study using electronic medical records (EMRs) to identify all female patients diagnosed with BC using the International Classification of Diseases-10 (ICD-10) codes (between C50 and C50.9). About 1209 cases with primary BC female patients were recognized based on histopathology reports. Further subclassification into TPBC and TNBC was performed. Statistical analysis was performed using Rv3.6.2 (R Studio, version 3.5.2, Boston, MA, USA). The descriptive data were presented as means and standard deviations (SD). Survival curves were approximated using the Kaplan-Meier method. The comparison between survival curves between both groups was achieved using the log-rank test. The multivariate model was constructed based on the identified predictors using univariate analysis. Results Univariate analysis of overall survival (OS) showed that mortality was higher in TNBC compared to TPBC (HR = 2.82, P-value <0.05). However, in a multivariate analysis, molecular subtypes did not show a significant effect on OS with a P-value of 0.94. We found that age at diagnosis has been associated with a 4% increase in mortality risk with a yearly rise in age. Conclusion In this limited retrospective cohort study, we found that TNBC may not be associated with a higher risk of death than TPBC. However, other factors, including age at diagnosis, surgical intervention, and lymphovascular invasion (LVI), have been observed to increase the risk of mortality. On the other hand, patients with TNBC were found to have a worse prognosis in terms of local recurrence. This information cannot be generalized to all patients with BC given the limitations of this study. Further, larger cohorts are needed to explore biological and treatment-related outcomes in patients with TNBC and TPBC.

Surgical confidence when operating among residents in surgery - a cross-sectional study (SCAR study).

BACKGROUND: Self-confidence, is one of the critical variables influencing surgical resident's abilities, and lack of confidence maybe a reason for not entering medical practice immediately. Measuring the level of confidence of senior surgical residents (SSRs) is a crucial step in assessing preparedness to practice. In this study, we aim to measure their confidence level and the factors that might contribute to it. METHODS: Cross-sectional survey conducted at King Abdulaziz University Hospital on SSRs in Saudi Arabia (SA). We approached 142 SSRs, 127 responded. Statistical analysis was performed using RStudio v 3.6.2. Descriptive statistics were performed using counts and percentages for categorical variables and using mean ± standard deviation for continuous variables. Multivariate linear regression (t-statistics) was used to assess the factors associated with confidence in performing essential procedures, while the association between demographics and residency-related factor with the number of completed cases was tested using Chi-square. The level of significance was determined as 0.05. RESULTS: Response rate was 89.4%. Among surveyed residents, 66% had completed < 750 cases as a primary surgeon. More than 90% of SSRs were confident in performing appendectomy, open inguinal hernia repair, laparoscopic cholecystectomy, and trauma laparotomy, while 88% were confident in being on-call in level-I trauma center. No difference was noted in confidence level in relation to the number of performed cases. Residents from the Ministry of Health accounted for 56.3% of the study population and showed a higher confidence level compared to others. 94% of SSRs plan to pursue fellowship training program. CONCLUSION: The study showed that the confidence of SSRs in performing common general surgery procedures was as expected. However, it's important to recognize that confidence doesn't necessarily reflect competence. Considering the majority of SSRs planned to pursue fellowship training programs, it may be time to consider changing the structure of surgical training in SA to a modular format to allow earlier and more intensive exposure.

Phenotype and Genotype of Saudi Pediatric Patients With Neurofibromatosis Type 1: A Seven-Year Multicenter Experience From Saudi Arabia.

Background Neurofibromatosis type 1 (NF1) is a complex disorder. Genetics and environment might be attributed as the leading cause of NF1, which is characterized by multisystemic involvement. We aim to elaborate on Saudi children's NF1 phenotypes and genotypes. Methods This study was conducted in the Ministry of National Guard Health Affairs (MNGHA), Saudi Arabia including three tertiary hospitals, using a retrospective cohort method. Electronic charts were reviewed to extract the variables. All Saudi pediatric patients aged less than 18 with NF1 were included. Consecutive sampling was used due to the limited number of patients. Results The study included 160 patients (81 males) with an average age of 8.08 years. Also, 33 (20.6%) patients had cutaneous neurofibroma while 31 (19.4%) patients had plexiform neurofibromas. Iris lisch nodules were seen in 33.75%. Optic pathway glioma was seen in 29 (18%) cases while non-optic pathway glioma was seen in 27 (17%) cases. Skeletal abnormalities were seen in 27 (17%) of cases. A first-degree relative with NF1 was seen in 83 (52%) of cases. Epilepsy was the presenting feature of 27 (17%) cases. Cognitive impairment was found in 15 (9.4%) patients. Genetic mutation was seen in 82/100 cases, the rest were negative. The types of mutations were as follows: nonsense 30 (36.6%); missense 20 (24.4%); splicing site mutation 12 (14.6%); frameshift 10 (12.2%); microdeletion 7 (8.5%); and whole gene deletion 3 (3.75%) patients. No phenotype-genotype correlation was seen. Conclusion In this cohort of Saudi pediatric patients with NF1, optic pathway glioma and other brain tumors were prevalent. The most common mutation is the nonsense mutation.

Histopathological examination of cases with acute appendicitis, A retrospective study at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.

Introduction: Appendicitis is one of the most prevalent abdominal emergencies globally. Despite the fact that acute appendicitis is a clinical diagnosis, preoperative imaging investigations are often conducted. Other disorders that might mimic acute appendicitis can occur in the appendix. The aim of this paper is to describe the histopathological findings of all appendectomy specimens. Methods: A retrospective study of 940 cases of appendectomy that were performed between 2010 and 2017 at King Abdulaziz University Hospital, Jeddah, Saudi Arabia were reviewed. The main outcome measured in this study is to describe the histopathological findings of all appendectomy specimens. The secondary outcomes measured in this study were the disease incidence in relation to age, and gender. Moreover, the accuracy of imaging diagnostic tools were also evaluated. Results: This study included 940 participants who underwent an appendectomy procedure. The patients' mean age was 23.4 years (±12.2), with a 3:2 male to female proportion. The incidence in males and females were 59.4% and 40.6%, respectively. Being male (p < 0.001), undergoing preoperative ultrasound (p < 0.001), having elevated white blood cells count (p < 0.001) was significantly associated with accurate diagnosis of acute appendicitis confirmed by histopathology. In this study, the negative cases of appendectomy that account for 14.4% were reported primarily as normal appendix with no inflammatory changes (7.44%) followed by other unexpected findings in the appendectomy specimen (3.93%) that included faecolith, granulomas, mucocele, endometriosis, food/fecal impaction, and schistosomiasis. Our study showed CT sensitivity as a diagnostic tool of acute appendicitis is 90.2%, and its accuracy is 89.4%, while US sensitivity is 46% and its accuracy is 52.4%. Conclusion: Histopathological evaluation after common procedures, such as appendectomy, is essential to avoid missing other pathologies in the appendix. Surgeons should be aware of the uncommon histopathology findings as some disorders call for additional management beyond appendectomy. The clinical details, radiological investigations including CT scan and histopathological diagnoses are required for better management in cases of appendicular lesions.

Patient handoffs among general surgery residents in Saudi Arabia: a cross-sectional study.

BACKGROUND: Communication failure is a common cause of adverse events. An essential element of communication among health care providers is patient handoff. Patient handoff is defined as a practice whereby a health care provider transfers a patient's care information to another health care provider to ensure the patient's safety and continuity of care. To explore this practice, we assessed patient handoffs among general surgery residents in Saudi Arabia. METHODS: A cross-sectional survey was conducted with individuals in accredited general surgery residency programs in Saudi Arabia between 2020 and 2021. RESULTS: Participants comprised 118 general surgery residents: 66 (57.3%) were female; 67 (72.8%) did not receive any formal training on patient handoff; and 35 (38.8%) reported that they were sometimes interrupted during the patient handoff process. The most common reason for such interruptions was medical personnel paging. Furthermore, 60 (68.1%) general surgery residents stated that these interruptions led to a decreased quality of effective communication, 39 (44.3%) believed it led to decreased quality of patient care, 63 (71.5%) believed it led to the loss of some information related to patient handoff, and 16 (18.1%) believed it led to patient harm. Finally, 31 (34.4%) general surgery residents believed that the existing handoff system at their institutions neither adequately protected the patients' safety nor allowed for continuity of care, and 51 (68%) reported that their institution did not have a standardized protocol for the verbal patient handoff process. There was a higher proportion of patients with minor harm among residents who did not, rarely or sometimes received verbal or written hand off instructions compare to those who did so always or most of the time (67% vs. 49%, respectively). CONCLUSION: The patient handoff process among general surgery residents in Saudi Arabia is subjective and is not standardized, and if not addressed, may lead to patient harm. Standardizing this process is paramount to improve patient safety.

Body Microbiota and Its Relationship With Benign and Malignant Breast Tumors: A Systematic Review.

Breast cancer is the most frequent type of cancer as well as one of the main causes of cancer-related mortality in women. Human microbial dysbiosis, which has been related to a range of malignancies, is one of the variables that may impact the chance of developing breast disorders. In this review, we aimed to investigate the relationship between breast cancer and benign breast tumors with dysbiosis of the microbiome at different body sites. We performed a systematic review of MEDLINE, Scopus, Ovid, and Cochrane Library to identify original articles published until July 2020 that reported studies of breast disease and microbiota. Twenty-four original articles were included in the study, which looked at the features and changes in breast, gut, urine, lymph node, and sputum microbial diversity in patients with benign and malignant breast tumors. In breast cancer, the breast tissue microbiome demonstrated changes in terms of bacterial load and diversity; in benign breast tumors, the microbiome was more similar to a malignant tumor than to normal breast tissue. Triple-negative (TNBC) and triple-positive (TPBC) types of breast cancer have a distinct microbial pattern. Moreover, in breast cancer, gut microbiota displayed changes in the compositional abundance of some bacterial families and microbial metabolites synthesis. Our review concludes that breast carcinogenesis seems to be associated with microbial dysbiosis. This information can be further explored in larger-scale studies to guide new prophylactic, diagnostic, and therapeutic measures for breast cancer.

Venom of the desert black snake Walterinnesia aegyptia enhances anti-tumor immunity via its beneficial modulatory effects on pro- and anti-tumorigenic inflammatory mediators in cultured colon cancer cells.

The role of inflammation in colon cancer is understood as a well-accepted factor that has the tendency to release multiple pro- and anti-tumorigenic inflammatory mediators. Inflammation-induced increased expression of anti-tumorigenic inflammatory mediators and decreased expression of pro-tumorigenic inflammatory mediators encourage beneficial inflammatory effects in terms of powerful anti-tumor immunity. The present study aims to screen the beneficial inflammatory effects of Walterinnesia aegyptia venom via determining its modulatory tendency on the expression of 40 pro- and anti-tumorigenic inflammatory mediators (cytokines/growth factors/chemokines) in LoVo human colon cancer cell line. LoVo-cells were treated with varying doses of crude venom of W. aegyptia. Cell viability was checked utilizing flow cytometry, and IC50 of venom was determined. Venom-induced inflammatory effects were evaluated on the expression of 40 different inflammatory mediators (12 anti-tumorigenic cytokines, 11 pro-tumorigenic cytokines, 7 pro-tumorigenic growth factors, 9 pro-tumorigenic chemokines and 1 anti-tumorigenic chemokine) in treated LoVo-cells [utilizing enzyme-linked immunosorbent assay (ELISA)] and compared with controls. Treatment of venom induced significant cytotoxic effects on inflamed LoVo-cells. IC50 treatment of venom caused significant modulations on the expression of 22 inflammatory mediators in treated LoVo-cells. The beneficial modulatory effects of venom were screened via its capability to significantly increase the expression of five powerful anti-tumorigenic mediators (IL-9, IL-12p40, IL-15, IL-1RA and Fractalkine) and decrease the expression of four major pro-tumorigenic mediators (IL-1ß, VEGF, MCP-1 and MCP-3). Walterinnesia aegyptia venom-induced beneficial modulations on the expression of nine crucial pro/anti-tumorigenic inflammatory mediators can be effectively used to enhance powerful anti-tumor immunity against colon cancer.

Outcomes of Non-metastatic Colon Cancer: A Single-Center Experience.

Background Colorectal cancer (CRC) is the most common gastrointestinal cancer. In the Saudi Cancer Registry, CRC ranked as the most common cancer in men and the third most common cancer in women. Data regarding the stage of CRC at presentation and patient demographics and outcomes in Saudi Arabia are lacking. This study aimed to investigate the prevalence, survival, and mortality rates of patients with non-metastatic CRC in a tertiary care hospital in Saudi Arabia.  Methods We conducted a retrospective chart review of patients diagnosed with adenocarcinoma of the colon or rectum at King Abdulaziz University Hospital between 2013 and 2017. Patients aged ≥18 years who presented with non-metastatic CRC and underwent curative resection were included. Patients with rectal cancer or metastatic colon cancer were excluded. Data on demographic characteristics, histopathological findings, tumor-node-metastasis stage, biomarkers, and surgical interventions were collected. Recurrence-free survival was defined as the time from surgery to the date of recurrence or death. All statistical analyses were performed using Stata/IC 15.1 (StataCorp, College Station, TX, USA). Results Among 260 patients diagnosed with CRC, 82 were included based on the inclusion/exclusion criteria. Among those patients, 65.9% were men and 47.5% were Saudi citizens. The mean age at the time of diagnosis was 60.8 years. Fifty-three patients (64.6%) had left-sided colon cancer. The mean tumor diameter was 52.6 mm. Most colon tumors were T3 lesions (71.3%), and 41% of patients did not have lymph node involvement (N0). Most patients (85.1%) underwent open surgery. In the multivariate analysis, only resection margin status and N stage (hazard ratio: 17.7 and 3.7, respectively) were identified as statistically significant factors affecting the recurrence-free survival. The one-, two-, and five-year recurrence-free rates were 80.5%, 66.5%, and 57.1%, respectively, and the one-, two-, and five-year and overall survival rates were 90.3%, 82.5%, and 82.5%, respectively. Conclusions We showed significant reductions in recurrence-free and overall survival within the first two years after surgical resection. Further prospective studies are needed to explore predictors.

Locally Advanced Breast Cancer: Treatment Patterns and Predictors of Survival in a Saudi Tertiary Center.

Background  Breast cancer (BC) is the most common cancer in the Kingdom of Saudi Arabia (KSA) and the second leading cause of cancer-related mortality. About 40% of BC in KSA is locally advanced BC (LABC), which has been associated with poorer survival compared with early diagnosed BC. Objective To review the presentation and outcomes of LABC, including the characteristics of the disease, different treatment modalities, overall survival (OS), disease-free survival (DFS), and local recurrence in relation to different radiotherapy (RT) techniques. Methods  We retrospectively reviewed the medical records of 153 female patients with pathologically proven LABC diagnosed at King Abdulaziz University Hospital, Jeddah, KSA, between 2009 and 2017. We obtained data on patient demographics, stage of cancer at diagnosis, tumor characteristics (subtype and receptor status), type of surgery, systemic treatments received (hormonal, targeted therapy, and chemotherapy), RT variables, and recurrence and death dates. Data were analyzed to assess OS and DFS by using Kaplan-Meier analyses and the log-rank test. Univariate and multivariate Cox proportional hazard regression analyses were used to explore and identify factors associated with survival. Results  The median survival time in the study population was 9.16 years. Older age (65+ years) was associated with worse OS and DFS than was younger age (<65 years) (hazard ratio (HR) 3.20, 95% CI 1.48-6.90, P = 0.003 and HR 2.21, 95% CI 1.12-4.36, P = 0.022, respectively). Regarding the type of surgery, having a mastectomy was associated with worse OS and DFS than was having a lumpectomy (HR 2.44, 95% CI 0.97-6.12, P = 0.05 and HR 2.41, 95% CI 1.13-5.14, P = 0.023, respectively). Positive estrogen and progesterone receptor status was associated with better OS and DFS than was a negative estrogen or progesterone receptor status (HR 0.13, 95% CI 0.05-0.30, P < 0.001 and HR 0.21, 95% CI 0.11-0.41, P < 0.001, respectively). Patients who received RT had a lower risk of recurrence than did those who did not receive RT (P = 0.011). Moreover, three-dimensional conformal RT was associated with lower local recurrence than intensity-modulated RT or volumetric-modulated arc therapy (P = 0.003). Conclusion  Multiple factors can affect the OS and DFS in LABC. Younger patients, having hormone-positive disease, and undergoing lumpectomy were associated with better outcomes. Adjuvant RT may improve local control and the use of three-dimensional conformal RT was superior for local control. Prospective studies with larger sample sizes are needed to further highlight these findings and to assess the role of chemotherapy and targeted therapy in patients with LABC.

Short-term outcomes of stents in obstructive rectal cancer: A systematic review and meta-analysis.

BACKGROUND: With acute obstruction due to rectal or recto-sigmoid cancer, the safety and success of deploying self-expandable metal stents has been controversial. The aim of this systematic review was to synthesize the existing evidence on the outcomes and complication rates of stent placement in these patients. METHODS: We performed a literature search of PubMed by using appropriate keywords, and manual reference screening of included articles was done. The article screening, data extraction, and quality assessment was done by four independent reviewers. A meta analyses was performed for the main outcome measures: technical and clinical success and complication rates. RESULTS: We identified 962 articles in the search. After applying inclusion and exclusion criteria, we included 32 articles in the meta-analysis. The pooled technical success rate across 26 studies that reported it was 97% [95% confidence interval (CI): 95%-99%] without evidence of significant heterogeneity (I2 = 0.0%, P = 0.84), and the clinical success rate across 26 studies that reported it was 69% (95% CI: 58%-79%) with evidence of significant heterogeneity (I2 = 81.7%, P < 0.001). The pooled overall complication rate across the 32 studies was 28% (95% CI: 20%-37%) with evidence of significant heterogeneity (I2 = 79.3%, P < 0.001). CONCLUSION: The use of rectal stents in obstructing rectal or recto-sigmoid tumors seems to be technically feasible. A high rate of technical success, however, does not always translate into clinical success. A considerable complication rate is associated with this approach. Randomized controlled trials are needed to compare the outcomes of rectal stent placement with those of surgery.

Impact of optional multidisciplinary tumor board meeting on the mortality of patients with gastrointestinal cancer: A retrospective observational study.

BACKGROUND: Multidisciplinary tumor board meetings (MDTs) have shown a positive effect on patient care and play a role in the planning of care. However, there is limited evidence of the association between MDTs and patient mortality and in-hospital morbidity for mixed cases of gastrointestinal (GI) cancer. AIM: To evaluate the influence of optional MDTs on care of patients with cancer to determine potential associations between MDTs and patient mortality and morbidity. METHODS AND RESULTS: This was a retrospective observational study at the referral center of King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia. Among all adult patients diagnosed with GI cancer from January 2017 to June 2019, 130 patients were included. We categorized patients into two groups: 66 in the control group (non-MDT) and 64 in the MDT group. The main outcome measure was overall mortality, measured by survival analysis. The follow-up was 100% complete. Four patients in the MDT group and 13 in the non-MDT group died (P = .04). The median follow-up duration was 294 days (interquartile range [IQR], 140-434) in the non-MDT group compared with 176 days (IQR, 103-466) in the MDT group (P = .20). There were no differences in intensive care unit or hospital length-of-stay or admission rates. The overall mortality at 2 years was 13% (95% confidence interval [CI], 0.06-0.66) in the MDT group and 38% (95% CI, 0.10-0.39) in the non-MDT group (P = .08). The MDT group showed a 72% (adjusted hazard ratio [HR], 0.28; 95% CI, 0.08-0.90; P = .03) decrease in mortality over time compared with the non-MDT group. CONCLUSIONS: MDTs were associated with decreased mortality over time. Thus, MDTs have a positive influence on patient care by improving survival and should be incorporated into care.

Unusual techniques in the management of enteroatmospheric fistula. Report of a case.

INTRODUCTION: Enteroatmospheric fistula (EAF) is one of the most challenging postoperative complications following gastrointestinal surgery. Different techniques have been reported for managing the open abdomen and controlling the effluent released from an EAF. PRESENTATION OF A CASE: We herein report the case of a patient who underwent bowel resection, complicated by the failure of the staple line, in the setting of an open abdomen. A male external catheter was anastomosed to the EAF opening to control the effluent and divert it away from the wound. In addition, Teflon pledgets were used to successfully patch a second, small EAF opening. DISCUSSION: An essential element in managing EAFs is wound care and controlling the effluent from the EAF to protect the wound. Different innovative techniques have been described to manage an EAF in the setting of an open abdomen. Anastomosing the male external catheter to the EAF opening is a simple and quick technique to control the EAF effluent. Other techniques can be applied at the same time to manage the wound. CONCLUSION: EAF is a very challenging complication. We presented a simple and effective technique to control the EAF effluent. Multidisciplinary teams are required to manage these patients successfully.

Laparoscopic colorectal cancer resections in the obese: a systematic review.

BACKGROUND: Laparoscopic colorectal cancer operations in obese patients pose technical challenges that may negatively impact oncologic adequacy. A meta-analysis was performed to assess the oncologic outcomes of laparoscopic colorectal cancer resections in obese compared to non-obese patients. Short- and long-term outcomes were assessed secondarily. METHODS: A systematic literature search was conducted from inception until October 01, 2014. Studies that compared outcomes of laparoscopic colorectal malignant neoplasms in obese and non-obese patients were selected for meta-analysis. Studies that defined obesity as body mass index (BMI) ≥ 30 kg/m2 were included. Oncologic, operative, and postoperative outcomes were evaluated. Pooled odds ratios (OR) and weighted mean differences (WMD) with 95 % confidence intervals (CI) were calculated using fixed-effects models. For oncologic and survival outcomes, a subgroup analysis was conducted for rectal cancer and a secondary analysis was conducted for Asian studies that used a BMI cutoff of 25 kg/m2. RESULTS: Thirteen observational studies with a total of 4550 patients were included in the meta-analysis. Lymph node retrieval, distal, and circumferential margins, and 5-year disease-free and overall survival were similar in the obese and non-obese groups. Conversion rate (OR 2.11, 95 % CI 1.58-2.81), postoperative morbidity (OR 1.54, 95 % CI 1.21-1.97), wound infection (OR 2.43, 95 % CI 1.46-4.03), and anastomotic leak (OR 1.65, 95 % CI 1.01-2.71) were all significantly increased in the obese group. CONCLUSIONS: Laparoscopic colorectal cancer operations in obese patients pose an increased technical challenge as demonstrated by higher conversion rates and higher risk of postoperative complications compared to non-obese patients. Despite these challenges, oncologic adequacy of laparoscopic colorectal cancer resections is comparable in both groups.

Initial assessment of patient handoff in accredited general surgery residency programs in the United States and Canada: a cross-sectional survey.

BACKGROUND: Communication errors are considered one of the major causes of sentinel events. Our aim was to assess the process of patient handoff among junior surgical residents and to determine ways in which to improve the handoff process. METHODS: We conducted nationwide surveys that included all accredited general surgery residency programs in the United States and Canada. RESULTS: Of the 244 American and 17 Canadian accredited surgical residency programs contacted, 65 (27%) and 12 (71%), respectively, participated in the survey. Of the American and Canadian respondents, 66% and 69%, respectively, were from postgraduate year (PGY) 1, and 32% and 29%, respectively, were from PGY 2; 85 (77%) and 50 (96%), respectively, had not received any training about patient handoff before their surgical residency, and 27% and 64%, respectively, reported that the existing handoff system at their institutions did not adequately protect patient safety. Moreover, 29% of American respondents and 37% of Canadian respondents thought that the existing handoffs did not support continuity of patient care. Of the American residents, 67% and 6% reported receiving an incomplete handoff that resulted in minor and major patient harm, respectively. These results mirrored those from Canadian residents (63% minor and 7% major harm). The most frequent factor reported to improve the patient handoff process was standardization of the verbal handoff. CONCLUSION: Our survey results indicate that the current patient handoff system contributes to patient harm. More efforts are needed to establish standardized forms of verbal and written handoff to ensure patient safety and continuity of care.

CONTEXTE: Les erreurs de communication sont considérées comme l'une des causes majeures des événements sentinelles. Notre but était d'évaluer le processus de transfert des patients chez les résidents junior en chirurgie et de trouver des façons de l'améliorer. MÉTHODES: Nous avons procédé à des sondages nationaux qui ont inclus tous les programmes agréés de résidence en chirurgie générale aux États Unis et au Canada. RÉSULTATS: Sur les 244 programmes agréés de résidence en chirurgie américains et les 17 canadiens, 65 (27 %) et 12 (71 %), respectivement, ont participé au sondage. Parmi les participants américains et canadiens, 66 % et 69 %, respectivement, étaient en première année de résidence (PGY 1) et 32 % et 29 %, respectivement, étaient en deuxième année de résidence (PGY 2); 85 (77 %) et 50 (96 %), respectivement, n'avaient reçu aucune formation sur le transfert des patients avant leur résidence en chirurgie et 27 % et 64 %, respectivement, ont déclaré que le système actuel de transfert de leur établissement n'assurait pas adéquatement la sécurité des patients. De plus, 29 % des participants américains et 37 % des participants canadiens ont dit estimer que le mode actuel de transfert ne favorisait pas la continuité des soins. Chez les résidents américains, 67 % et 6 % ont déclaré recevoir un rapport de transfert incomplet susceptible d'entraîner un préjudice mineur et majeur, respectivement, pour le patient. Ces réponses correspondaient à celles des résidents canadiens (63 % et 7 %, respectivement, en ce qui concerne les préjudices mineurs et majeurs). Le facteur mentionné comme le plus propice à une amélioration du processus de transfert des patients était la standardisation du rapport verbal. CONCLUSION: Les résultats de nos sondages indiquent que le système actuel de transfert des patients serait préjudiciable à ces derniers. Il faudra travailler à standardiser les processus de transfert et de rapports verbaux et écrits pour assurer la sécurité des patients et la continuité des soins.

Atrial fibrillation as an unexpected complication after peroral endoscopic myotomy (POEM): a case report.

Peroral endoscopic myotomy (POEM) is an entirely endoscopic approach for the treatment of achalasia. This new procedure has been shown to be safe, effective, and associated with only minor complications in the postoperative period. This case report describes the development of atrial fibrillation after POEM secondary to direct compression from a hematoma in the submucosal tunnel. To our knowledge, this is the first report of a delayed hematoma after POEM. This procedure is still novel, and it is important to continue to share information about potential complications and long-term results. This report also includes several interesting radiographic images to illustrate what occurred. Finally, we provide a brief review of the literature on complications that have been described after POEM.

Advances in the diagnosis and management of inflammatory bowel disease: challenges and uncertainties.

Over the past two decades, several advances have been made in the management of patients with inflammatory bowel disease (IBD) from both evaluative and therapeutic perspectives. This review discusses the medical advancements that have recently been made as the standard of care for managing patients with ulcerative colitis (UC) and Crohn's Disease (CD) and to identify the challenges associated with implementing their use in clinical practice. A comprehensive literature search of the major databases (PubMed and Embase) was conducted for all recent scientific papers (1990-2013) giving the recent updates on the management of IBD and the data were extracted. The reported advancements in managing IBD range from diagnostic and evaluative tools, such as genetic tests, biochemical surrogate markers of activity, endoscopic techniques, and radiological modalities, to therapeutic advances, which encompass medical, endoscopic, and surgical interventions. There are limited studies addressing the cost-effectiveness and the impact that these advances have had on medical practice. The majority of the advances developed for managing IBD, while considered instrumental by some IBD experts in improving patient care, have questionable applications due to constraints of cost, lack of availability, and most importantly, insufficient evidence that supports their role in improving important long-term health-related outcomes.

Cost effectiveness of mesh prophylaxis to prevent parastomal hernia in patients undergoing permanent colostomy for rectal cancer.

BACKGROUND: Parastomal hernia (PSH) is common after stoma formation. Studies have reported that mesh prophylaxis reduces PSH, but there are no cost-effectiveness data. Our objective was to determine the cost effectiveness of mesh prophylaxis vs no prophylaxis to prevent PSH in patients undergoing abdominoperineal resection with permanent colostomy for rectal cancer. STUDY DESIGN: Using a cohort Markov model, we modeled the costs and effectiveness of mesh prophylaxis vs no prophylaxis at the index operation in a cohort of 60-year-old patients undergoing abdominoperineal resection for rectal cancer during a time horizon of 5 years. Costs were expressed in 2012 Canadian dollars (CAD$) and effectiveness in quality-adjusted life years. Deterministic and probabilistic sensitivity analyses were performed. RESULTS: In patients with stage I to III rectal cancer, prophylactic mesh was dominant (less costly and more effective) compared with no mesh. In patients with stage IV disease, mesh prophylaxis was associated with higher cost (CAD$495 more) and minimally increased effectiveness (0.05 additional quality-adjusted life years), resulting in an incremental cost-effectiveness ratio of CAD$10,818 per quality-adjusted life year. On sensitivity analyses, the decision was sensitive to the probability of mesh infection and the cost of the mesh, and method of diagnosing PSH. CONCLUSIONS: In patients undergoing abdominoperineal resection with permanent colostomy for rectal cancer, mesh prophylaxis might be the less costly and more effective strategy compared with no mesh to prevent PSH in patients with stage I to III disease, and might be cost effective in patients with stage IV disease.

Endometriosis of the appendix: Report of three cases.

Endometriosis of the appendix is an entity of extragonadal endometriosis. It commonly affects women in the childbearing age with a wide spectrum of clinical manifestations. Women can present with symptoms mimicking acute appendicitis or chronic pelvic pain. The surgical management varies from simple appendectomy to right hemicolectomy depending on the clinical findings. We report 3 cases of endometriosis of the appendix presenting with appendiceal intussusception. The surgical literature is reviewed and current surgical management is discussed.
