RESUMEN
BACKGROUND: Loop ileostomy closure is a common procedure in colorectal surgery. Often seen as a simple operation associated with a low complication rate, it still leads to lengthy hospitalizations. Reducing postoperative complications and ileus rates could lead to a shorter length of stay and even ambulatory surgery. OBJECTIVES: This study aimed to assess the safety and feasibility of ileostomy closure performed in a 23-hour hospitalization setting using a standardized enhanced recovery pathway. DESIGN: Randomized controlled trial. SETTINGS: Two high-volume colorectal surgery centers. PATIENTS: Healthy adults undergoing elective ileostomy closure from July 2019 to January 2022. INTERVENTION: All patients were enrolled in a standardized enhanced recovery pathway specific to ileostomy closure, including daily irrigation of efferent limb with a nutritional formula for 7 days before surgery. Patients were randomly allocated to either conventional hospitalization (n = 23) or a 23-hour stay (n = 24). MAIN OUTCOME MEASURES: Primary outcome was total length of stay and secondary outcomes were 30-day rates of readmission, postoperative ileus, surgical site infections, and postoperative morbidity and mortality. RESULTS: A total of 47 patients were ultimately randomly allocated. Patients in the 23-hour hospitalization arm had a shorter median length of stay (1 vs 2 days, p = 0.02) and similar rates of readmission (4% vs 13%, p = 0.35), postoperative ileus (none in both arms), surgical site infection (0% vs 4%, p = 0.49), postoperative morbidity (21% vs 22%, p = 1.00), and mortality (none in both arms). LIMITATIONS: Due to coronavirus disease 2019, access to surgical beds was greatly limited, leading to a shift toward ambulatory surgery for ileostomy closure. The study was terminated early, which affected its statistical power. CONCLUSION: Loop ileostomy closures as 23-hour stay procedures are feasible and safe. Ileus rate might be reduced by preoperative intestinal stimulation with nutritional formula through the stoma's efferent limb, although specific randomized controlled trials are needed to confirm this association.

CIERRE DE ILEOSTOMA EN ASA COMO PROCEDIMIENTO AMBULATORIO DE HORAS CON ESTMULO PREOPERATORIO ENTERAL EFERENTE ESTUDIO ALEATORIO CONTROLADO: ANTECEDENTES:El cierre de la ileostomía en asa es un procedimiento común en la cirugía colorrectal. A menudo vista como una operación simple asociada con bajas tasas de complicaciones, aún conduce a largas hospitalizaciones. La reducción de las complicaciones postoperatorias y las tasas de íleo podría conducir a una estadía hospitalaria más corta o incluso a una cirugía ambulatoria.OBJETIVOS:El presente estudio pretende evaluar la seguridad y la viabilidad del cierre de ileostomía realizadas en un entorno de hospitalización de 23 horas utilizando una vía de recuperación mejorada y estandarizada.DISEÑO:Estudio aleatorio controladoAJUSTES:Dos centros de cirugía colorrectal de gran volúmenPACIENTES:Adultos sanos sometidos a cierre electivo de ileostomía, desde Julio de 2019 hasta Enero de 2022.INTERVENCIÓN:Todos los pacientes fueron inscritos en una vía de recuperación mejorada y estandarizada específica para el cierre de la ileostomía, incluyendo la irrigación diaria de la extremidad eferente del intestino asociada a una fórmula nutricional durante 7 días previos a la cirugía. Los pacientes fueron asignados aleatoriamente en hospitalización convencional (n = 23) o a una estadía de 23 horas (n = 24).PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la duración total de la estadía hospitalaria y los resultados secundarios fueron las tasas de reingreso a los 30 días, el íleo postoperatorio, las infecciones de la herida quirúrgica, la morbilidad y mortalidad postoperatorias.RESULTADOS:Finalmente fueron randomizados un total de 47 pacientes. Aquellos que se encontraban en el grupo de hospitalización de 23 horas tuvieron una estadía media más corta (1 día versus 2 días, p = 0,02) y tasas similares de reingreso (4% vs 13%, p = 0,35), de íleo postoperatorio (ninguno en ambos brazos), de infección del sitio quirúrgico (0 vs 4%, p = 0,49), de morbilidad postoperatoria (21% vs 22%, p > 0,99) y de mortalidad (ninguna en ambos brazos).LIMITACIONES:Debido a la pandemia SARS CoV-2, el acceso a las camas quirúrgicas fue muy limitado, lo que llevó a un cambio hacia la cirugía ambulatoria para el cierre de ileostomías. El estudio finalizó anticipadamente, lo que afectó su poder estadístico.CONCLUSIÓN:Los cierres de ileostomía en asa como procedimientos de estadía de 23 horas son factibles y seguros. La tasa de íleo podría reducirse mediante la estimulación intestinal preoperatoria a través de la rama eferente del estoma asociada a fórmulas nutricionales, por lo que se necesitan estudios randomizados específicos para confirmar esta asociación.

AIM: The standard treatment for low rectal cancer is preoperative chemoradiotherapy followed by surgery with low anterior resection with diverting ileostomy or abdominoperineal resection, both of which have significant long-term effects on bowel and sexual function. Due to the high morbidity of surgery, there has been increasing interest in nonoperative management for low rectal cancer. The aim of this work is to conduct a pan-Canadian Phase II trial assessing the safety of nonoperative management for low rectal cancer. METHOD: Patients with Stage II or III low rectal cancer completing chemoradiotherapy according to standard of care at participating centres will be assessed for complete clinical response 8-14 weeks following completion of chemoradiotherapy. Subjects achieving a clinical complete response will undergo active surveillance including endoscopy, imaging and bloodwork at regular intervals for 24 months. The primary outcome will be the rate of local regrowth 2 years after chemoradiotherapy. Nonoperative management will be considered safe (i.e. as effective as surgery to achieve local control) if the rate of local regrowth is ≤30% and surgical salvage is possible for all local regrowths. Secondary outcomes will include disease-free and overall survival. CONCLUSION: The results will be highly clinically relevant, as it is expected that nonoperative management will be safe and lead to widespread adoption of nonoperative management in Canada. This change in practice has the potential to decrease the number of patients requiring surgery and the costs associated with surgery and long-term surgical morbidity.

BACKGROUND: We assessed feasibility and safety of laparoscopic sigmoidectomy for complicated fistulizing diverticular disease in a tertiary care colorectal center. METHODS: A single-center retrospective study of patients undergoing sigmoidectomy for fistulizing diverticular disease between 2011 and 2021 was realized. Primary outcomes were rates of conversion to open surgery and severe postoperative morbidity at 30 days. Secondary outcomes included rates of postoperative bladder leaks on cystogram. RESULTS: Among the 104 patients, 32.7% had previous laparotomy. Laparoscopy was the initial approach in 103 (99.0%), with 6 (5.8%) conversions to laparotomy. Clavien-Dindo grade ≥ III complication rate at 30 days was 10.6%, including two (1.9%) anastomotic leaks. The median postoperative length of stay was 4.0 days. Seven (6.7%) patients underwent reoperation, six (5.8%) were readmitted, and one (0.9%) died within 30 days. Twelve (11.5%) ileostomies were created initially, and two (1.9%) were created following anastomotic leaks. At last follow-up, 101 (97.1%) patients were stoma-free. Urgent surgeries had a higher rate of severe postoperative complications. Among colovesical fistula patients (n = 73), postoperative cystograms were performed in 56.2%, identifying two out of the three bladder leaks detected on closed suction drains. No differences in postoperative outcomes occurred between groups with and without postoperative cystograms, including Foley catheter removal within seven days (73.2% vs. 90.6%, p = 0.08). CONCLUSIONS: Laparoscopic surgery for complicated fistulizing diverticulitis showed low rates of severe complications, conversions to open surgery and permanent stomas in high-volume colorectal center.

PURPOSE: To assess the safety and efficacy of synchronous treatments for rectal (RC) and prostate (PC) cancers. METHODS: Single-center retrospective study (2007-2021) of patients treated with neoadjuvant radiotherapy (RT) and total mesorectal excision (TME) for RC with synchronous PC treatment. The endpoints were 30-day postoperative severe complications, R0 resection rates, 3-year disease-free survival (DFS) and 3-year overall survival (OS). RESULTS: Among the 16 patients, 15 (93.7%) received neoadjuvant pelvic RT (40-50.4 Gray) followed by either transperineal high dose rate prostate brachytherapy (62.5%), prostate external RT boost (25.0%), or androgen deprivation therapy (ADT) alone (6.3%). One (6.3%) patient received neoadjuvant rectal brachytherapy and ADT. Pelvic RT was combined with chemotherapy in 87.5% of cases. TME was performed in all patients with low anterior resection (87.5%) or abdominoperineal resection (12.5%), primarily using minimally invasive surgery (87.5%). The R0 resection rate was 93.8%. Six (37.5%) patients experienced 30-day Clavien-Dindo grade IIIb complications, including one (7.1%) anastomotic leak. After a median follow-up of 39.0 months, 63.6% of diverting ileostomies were reversed. Three-year DFS from RC was 71.4% (CI 40.2-88.3) and 3-year OS was 84.4% (CI 95% 50.4-95.9). No PC recurrence or death occurred. CONCLUSIONS: Synchronous management of RC and PC with pelvic RT followed by curative prostate RT doses and TME showed acceptable morbidity and oncologic results. Prostate brachytherapy, the most commonly used treatment modality, allowed avoidance of prostatectomy and additional external RT to the rectum. PC should not limit the curative intent of RC, as all recurrences were from rectal origin.

BACKGROUND: Early ileostomy closure (EIC), ≤ 2 weeks from creation, is a relatively new practice. Multiple studies have demonstrated that this approach is safe, feasible, and cost-effective. Despite the demonstrated benefits, this is neither routine practice, nor has it been studied, in North America. This study aimed to assess patient and surgeon perspectives about EIC. METHODS: A mixed-methods, cross-sectional study of patients and surgeons was performed. Rectal cancer survivors from a single institution who underwent restorative proctectomy with diverting loop ileostomy and subsequent closure within the last 5 years were contacted. North American surgeons with high rectal cancer volumes (> 20 cases/year) were included. Surveys (patients) and semi-structured interviews (surgeons) were conducted. Analysis employed descriptive statistics and thematic analysis, respectively. RESULTS: Forty-eight patients were surveyed (mean age 65.1 ± 11.8 years; 54.2% male). Stoma closure occurred after a median of 7.7 months (IQR 4.8-10.9) and 50.0% (24) found it "difficult" or "very difficult" to live with their stoma. Patients considered improvement in quality of life and quicker return to normal function the most important advantages of EIC, whereas the idea of two operations in two weeks being too taxing on the body was deemed the biggest disadvantage. Most patients (35, 72.9%) would have opted for EIC. Surgeon interviews (15) revealed 4 overarching themes: (1) there are many benefits to EIC; (2) specific patient characteristics would make EIC an appropriate option; (3) many barriers to implementing EIC exist; and (4) many logistical hurdles need to be addressed for successful implementation. Most surgeons (12, 80.0%) would "definitely want to participate" in a North American randomized-controlled trial (RCT) on EIC for rectal cancer patients. CONCLUSIONS: Implementing EIC poses many logistical challenges. Both patients and surgeons are interested in further exploring EIC and believe it warrants a North American RCT to motivate a change in practice.

BACKGROUND: Self-expanding metal stents as a bridge to surgery in acute malignant large-bowel obstruction has gained popularity. However, long-term oncologic outcomes have not been well established. OBJECTIVE: To investigate long-term oncologic outcomes of patients undergoing curative resection after the placement of a colonic stent compared with emergency surgery for acute malignant large-bowel obstruction. DESIGN: This is a retrospective study. SETTING: All patients presenting at 3 tertiary care centers between April 2002 and December 2012 with a diagnosis of complete malignant large-bowel obstruction were reviewed. Patients with disease distal to the hepatic flexure were selected for analysis. PATIENTS: One hundred twenty-two patients who underwent either emergency surgery or placement of a colonic stent with curative intent were included. INTERVENTIONS: Patients receiving emergency surgery within 24 hours of presenting with obstructive symptoms, including those with failed stents, were included in the emergency surgery group. All patients with clinically successful stent deployment before surgery were included in the stent group. MAIN OUTCOME MEASURES: Overall survival and disease-free survival were calculated using the Kaplan-Meier method. RESULTS: Sixty-four patients underwent emergency surgery, and 58 patients underwent placement of a self-expanding metal stent. Groups were similar in terms of sex, tumor stage and grade, and Charlson and Charlson-Age Comorbidity Index scores. Patients in the surgery group were older than patients in the stent group. There were no differences in the number of lymph nodes harvested, positive nodes, rates of vascular and perineural invasion, or utilization of chemotherapy. Thirty-day mortality after resection was similar between groups (7.41% vs 4.41%; p > 0.05). Patients who underwent colonic stenting as a bridge to surgery had similar 10-year overall survival (40.5% vs 32.7%; p = 0.13) and 10-year disease-free survival (40.2% vs 33.8%; p = 0.26) compared with those who underwent emergency surgery. Similar results were seen on intention-to-treat analysis. LIMITATIONS: This was a small retrospective study. CONCLUSIONS: Stent insertion followed by oncologic resection is associated with similar overall survival and disease-free survival compared with emergency resection. Stent insertion as a bridge to surgery should be considered in patients presenting with malignant colorectal obstruction.

ANTECEDENTES: Los stents metálicos autoexpandibles como puente a una cirugía en la obstrucción maligna aguda del colon han ganado popularidad. Sin embargo, no se han establecido bien los resultados oncológicos a largo plazo. OBJETIVO: Investigar los resultados oncológicos a largo plazo de los pacientes sometidos a resección curativa después de la colocación de un stent colónico en comparación con la cirugía de urgencia para la obstrucción maligna aguda del colon. DISEO: Estudio retrospectivo. MBITO: Entre abril de 2002 y diciembre de 2012, se revisaron todos los pacientes que acudieron a tres centros de tercer nivel con un diagnóstico de obstrucción maligna completa del colon. Se seleccionaron para el análisis los pacientes con enfermedad distal al ángulo hepático. PACIENTES: Se incluyeron 122 pacientes que fueron operados de urgencia o a una colocación de un stent colónico con intención curativa. PROCEDIMIENTOS: Los pacientes que se sometieron a cirugía de urgencia dentro de las 24 horas posteriores a la presentación de síntomas obstructivos; se incluyeron aquellos con stents fallidos en el grupo de cirugía de urgencia. Todos los pacientes con colocación clínicamente exitosa del stent antes de la cirugía se incluyeron en el grupo de stent. PRINCIPALES VARIABLES ANALIZADAS: La sobrevida global y la sobrevida libre de enfermedad se calcularon mediante el método de Kaplan-Meier. RESULTADOS: Sesenta y cuatro pacientes fueron llevados a cirugía urgente y en 58 pacientes se colocó de un stent metálico autoexpandible. Los grupos fueron similares en relación a sexo, estadio y grado del tumor, puntuación de comorbilidad de Charlson y Charlson-Age. Los pacientes del grupo de cirugía eran mayores que los del grupo de stents. No hubo diferencias en el número de ganglios linfáticos recolectados, ganglios positivos, tasas de invasión vascular y perineural o utilización de quimioterapia. La mortalidad a los 30 días después de la resección fue similar entre los grupos (7,41% frente a 4,41%; p> 0,05). Los pacientes que se sometieron a la colocación de un stent colónico como puente a la cirugía tuvieron una sobrevida general a diez años similar (40,5% vs 32,7%; p = 0,13) y una sobrevida libre de enfermedad a diez años (40,2% vs 33,8%, respectivamente; p = 0,26) en comparación a los operados de urgencia. Se observaron resultados similares en el análisis por intención de tratamiento. LIMITACIONES: Estudio retrospectivo reducido. CONCLUSIONES: La utilización de un stent y posteriormente la resección oncológica se asocia a una sobrevida general y una sobrevida libre de enfermedad similar en comparación con la resección de urgencia. La utilización de un stent como puente a la cirugía debe considerarse en pacientes que presentan obstrucción colorrectal maligna. Consulte Video Resumen en http://links.lww.com/DCR/B714.

BACKGROUND: End-stage renal disease (ESRD) and renal replacement therapy (RRT) are important risk factors for post-operative morbidity and mortality but remains poorly reported in colorectal surgery. This study aims to evaluate postoperative outcomes of ESRD patients under RRT undergoing colorectal resection. METHODS: All ESRD patients under RRT who underwent colorectal resection between 2006 and 2019 were retrospectively reviewed. Perioperative outcomes were analysed, such as risk factors of postoperative complications. RESULTS: Forty-two patients were analysed, including 27 emergency and 15 elective surgeries. The most frequent indication was acute colonic ischemia for emergency and malignancy for elective procedures. Laparoscopic approach was used in 12 patients (29%), without difference between elective and emergency groups. Postoperative severe complications rate (including deaths) was 50% (21/42), including 56% (15/27) and 40% (6/15) in emergency and elective groups, respectively (p = .334). Anastomotic leak was observed in 3 of the 23 patients (13%) undergoing digestive anastomosis, (1 in emergency and 2 in elective groups, p = .246). The postoperative mortality rate was 29%, not significantly different between groups. The median hospital stay was 14.5 days (8-42). At univariate analysis, history of cardiac event (p = .028) and open approach (p = .040) were associated with severe complications, and ASA score >3 (p = .043), history of cardiac event (p = .001) and diabetes (p = .030) associated with mortality. CONCLUSIONS: Colorectal surgery in ESRD patient exposes to high risk of morbidity and mortality, even in the elective setting, especially in patients with comorbidities like cardiac event and diabetes. Careful patient selection and closed management is required in such fragile patients.

AIM: It is well established that (i) magnetic resonance imaging, (ii) multidisciplinary cancer conference (MCCs), (iii) preoperative radiotherapy, (iv) total mesorectal excision surgery and (v) pathological assessment as described by Quirke are key processes necessary for high quality, rectal cancer care. The objective was to select a set of multidisciplinary quality indicators to measure the uptake of these clinical processes in clinical practice. METHOD: A multidisciplinary panel was convened and a modified two-phase Delphi method was used to select a set of quality indicators. Phase 1 included a literature review with written feedback from the panel. Phase 2 included an in-person workshop with anonymous voting. The selection criteria for the indicators were strength of evidence, ease of capture and usability. Indicators for which ≥90% of the panel members voted 'to keep' were selected as the final set of indicators. RESULTS: During phase 1, 68 potential indicators were generated from the literature and an additional four indicators were recommended by the panel. During phase 2, these 72 indicators were discussed; 48 indicators met the 90% inclusion threshold and included eight pathology, five radiology, 11 surgical, six radiation oncology and 18 MCC indicators. CONCLUSION: A modified Delphi method was used to select 48 multidisciplinary quality indicators to specifically measure the uptake of key processes necessary for high quality care of patients with rectal cancer. These quality indicators will be used in future work to identify and address gaps in care in the uptake of these clinical processes.

PURPOSE: Parastomal hernia (PSH) is a frequent complication of stoma creation during colorectal surgery. Radiological classification systems have been proposed for PSH but are primarily used for research. Our objective was to determine if PSH radiological classification at diagnosis could predict the need for surgical repair during follow-up. METHODS: In this retrospective cohort study, we reviewed 705 postoperative CT scans from 154 patients with permanent stoma creation from 2015 to 2018. Patients were included for analysis if a primary PSH was diagnosed on any exam. PSH were classified according to the European Hernia Society (EHS) and Moreno-Matias (MM) classification systems. RESULTS: The incidence of radiological PSH was 41% (63/154) after a median radiological follow-up of 19.2 months (interquartile range, 10.9-32.9). Surgical repair was required in 17 of 62 patients with a primary PSH. There was no significant correlation between PSH classification and surgical hernia repair for either the EHS (p = 0.56) or MM classification systems (p = 0.35) in a univariate analysis. However, in a multivariate analysis, the type of PSH according to the EHS classification was significantly correlated with PSH repair during follow-up (p = 0.02). Type III PSH were associated with a lower incidence of surgical hernia repair as compared with type I, with a hazard ratio (HR) of 0.01 (95% CI, <0.00-0.20). A similar correlation was not seen using the MM classification (p = 0.10). CONCLUSION: EHS classification of PSH was significant correlated with the need for surgical repair during short-term follow-up. Prospective studies are required to establish a potential role in patient care.

INTRODUCTION: Postoperative pain following colorectal surgery is associated with a significant use of opioids. Recently, regional anesthesia, such as the posterior quadratus lumborum block (QL2), has been proposed to improve pain relief and reduce opioid use. However, the benefit of the QL2 on postoperative pain control remains controversial. METHODS: We conducted a randomized controlled trial of patients undergoing colorectal surgery at the CHU de Québec-Université Laval. Patients were randomized to regional QL2 anesthesia with 150 mg of ropivacaine combined with standard analgesia or to QL2 with a sham intervention and standard analgesia. Our primary outcome was postoperative opioid administration at 24 h. Secondary outcomes included opioid administration in the post-anesthesia care unit (PACU), at 48 h and at hospital discharge, postoperative pain scores, delay in resumption of intestinal transit, nausea and vomiting, and hospital length of stay. RESULTS: A total of 62 patients were enrolled from November 2017 to February 2018. QL2 regional anesthesia compared with a sham intervention was not associated with a reduction in postoperative morphine dose equivalent (100.2 mg, 95% CI 68.9-131.5 versus 88.7 mg, 95% CI 59.3-118.0, p = 0.81, respectively). Compared to QL2 regional anesthesia, postoperative pain scores in the control group were lower although statistical significance was not consistent for all postoperative time points. Other secondary outcomes were comparable between both groups. CONCLUSION: We did not observe a reduction in postoperative opioid administration at 24 h with a posterior quadratus lumborum block regional anesthesia in patients undergoing elective colorectal surgery.

INTRODUCTION: Transanal total mesorectal excision (taTME) is a novel approach to surgery for rectal cancer. The technique has gained significant popularity in the surgical community due to the promising ability to overcome technical difficulties related to the access of the distal pelvis. Recently, Norwegian surgeons issued a local moratorium related to potential issues with the safety of the procedure. Early adopters of taTME in Canada have recognized the need to create guidelines for its adoption and supervision. The objective of the statement is to provide expert opinion based on the best available evidence and authors' experience. METHODS: The procedure has been performed in Canada since 2014 at different institutions. In 2016, the first Canadian taTME congress was held in the city of Toronto, organized by two of the authors. In early 2019, a multicentric collaborative was established [The Canadian taTME expert Collaboration] which aimed at ensuring safe performance and adoption of taTME in Canada. Recently surgeons from 8 major Canadian rectal cancer centers met in the city of Toronto on December 7 of 2019, to discuss and develop a position statement. There in person, meeting was followed by 4 rounds of Delphi methodology. RESULTS: The generated document focused on the need to ensure a unified approach among rectal cancer surgeons across the country considering its technical complexity and potential morbidity. The position statement addressed four domains: surgical setting, surgeons' requirements, patient selection, and quality assurance. CONCLUSIONS: Authors agree transanal total mesorectal excision is technically demanding and has a significant risk for morbidity. As of now, there is uncertainty for some of the outcomes. We consider it is possible to safely adopt this operation and obtain adequate results, however for this purpose it is necessary to meet specific requirements in different domains.

BACKGROUND: Liver resection being the only potentially curative treatment for patients with liver metastasis, it is critical to select the appropriate preoperative imaging modality. The aim of this study was to assess the impact of preoperative gadoxetic acid-enhanced MRI compared to a conventional extracellular gadolinium-enhanced MRI on the surgical management of colorectal and neuroendocrine liver metastasis. METHODS: We included 110 patients who underwent both a gadoxetic acid-enhanced MRI (hepatospecific contrast) and conventional extracellular gadolinium for the evaluation of colorectal or neuroendocrine liver metastases, from January 2012 to December 2015 at the CHU de Québec - Université Laval. When the number of lesions differed, a hepatobiliary surgeon evaluated if the gadoxetic acid-enhanced MRI modified the surgical management. RESULTS: Gadoxetic acid-enhanced MRI found new lesions in 25 patients (22.7%), excluded lesions in 18 patients (16.4%) and identified the same number in 67 patients (60.9%). The addition of the gadoxetic acid-enhanced MRI directly altered the surgical management in 19 patients overall (17.3% (95% CI [10.73-25.65])). CONCLUSION: Despite the additional cost associated with gadoxetic acid-enhanced MRI compared to conventional extracellular gadolinium-enhanced MRI, the use of this contrast agent has a significant impact on the surgical management of patients with liver metastases.

BACKGROUND: Congenital diaphragmatic hernia is an unusual condition in the adult population because it is mostly a neonatal diagnosis. This entity may be triggered by pregnancy and threaten the life of the mother and her fetus. CASE: This report presents the case of a maternal diaphragmatic hernia diagnosed at 35 weeks of pregnancy with epigastric pain, nausea, and vomiting. Patient developed respiratory distress, and a radiograph revealed left lung collapse. A chest tube was inserted for a presumed tension pneumothorax. The patient's condition deteriorated, and a diaphragmatic hernia containing the stomach, transverse colon, and small bowel was diagnosed. The patient underwent laparotomy with Caesarean section, hernia reduction, and diaphragmatic repair. CONCLUSION: A high degree of suspicion is required to avoid misdiagnosis and management delay. Surgical treatment must be individualized according to gestational age and clinical setting.

Background: Transanal endoscopic microsurgery has become the standard of treatment for rectal villous adenomas. However, the role of preoperative imaging for these lesions is not clear. The aim of this study was to compare the value of preoperative imaging and surgeon clinical staging in the preoperative evaluation of patients with rectal villous adenomas having transanal endoscopic microsurgery resection. Methods: We conducted a single-centre comparative retrospective cohort study of patients who underwent transanal endoscopic microsurgery surgery for rectal villous adenomas from 2011 to 2013. The intervention was preoperative imaging versus surgeon clinical staging. The primary outcome was the accuracy of clinical staging by preoperative imaging and surgeon clinical staging according to the histopathologic staging. Results: A total of 146 patients underwent transanal endoscopic microsurgery surgery for rectal villous adenomas. One hundred and twelve (76.7%) of those patients had no preoperative imaging while 34 patients (23.3%) had either endorectal ultrasound (22 patients) or magnetic resonance imaging (12 patients). Surgeon staging was accurate in 89.3% of cases whereas staging by endorectal ultrasound was accurate in 40.9% cases and magnetic resonance imaging was accurate in 0% of cases. In the imaging group, inaccurate staging would have led to unnecessary radical surgery in 44.0% of patients. Conclusion: This study was subject to selection bias because of its retrospective nature and the limited number of patients with imaging. Patients with rectal villous tumours without invasive carcinoma on biopsies and without malignant characteristics on appearance in the judgment of an experienced colorectal surgeon might not benefit from preoperative imaging before undergoing transanal endoscopic microsurgery procedures.
Contexte: La microchirurgie endoscopique transanale est devenue le traitement standard des adénomes villeux rectaux. La valeur de l'imagerie préopératoire pour le traitement de ces lésions n'est toutefois pas bien établie. Cette étude visait à comparer l'exactitude de la stadification par imagerie préopératoire et de la stadification clinique par le chirurgien dans le cadre de l'évaluation préopératoire des patients atteints d'adénomes villeux rectaux qui subissent une résection par microchirurgie endoscopique transanale. Méthodes: Nous avons mené une étude de cohorte rétrospective comparative monocentrique chez des patients ayant subi une microchirurgie endoscopique transanale pour un adénome villeux rectal entre 2011 et 2013. Les interventions comparées étaient la stadification par imagerie préopératoire et la stadification clinique par le chirurgien. L'issue principale était l'exactitude de la stadification clinique par imagerie préopératoire et de la stadification clinique par le chirurgien, confirmée par stadification histopathologique. Résultats: Au total, 146 patients ont subi une microchirurgie endoscopique transanale pour le traitement d'un adénome villeux rectal. De ces patients, 112 (76,7 %) n'avaient pas subi d'imagerie préopératoire et 34 (23,3 %) avaient subi une échographie endorectale (22 patients) ou une imagerie par résonance magnétique (12 patients). La stadification par le chirurgien était exacte dans 89,3 % des cas, contre 40,9 % des cas pour l'échographie endorectale et 0 % des cas pour l'imagerie par résonnance magnétique. Dans le groupe ayant subi une imagerie, l'inexactitude de la stadification aurait mené à une chirurgie radicale inutile pour 44,0 % des patients. Conclusion: Cette étude comportait un biais de sélection en raison de sa nature rétrospective et du nombre limité de patients ayant subi une imagerie. L'imagerie préopératoire avant une microchirurgie endoscopique transanale pourrait ne présenter aucun avantage pour les patients présentant des tumeurs villeuses rectales dans les cas où aucun carcinome invasif n'a été détecté par biopsie et où un chirurgien colorectal chevronné n'a détecté aucune caractéristique maligne.

OBJECTIVE: To evaluate family medicine residents' training in, knowledge about, and perceptions of digital rectal examination (DRE). DESIGN: Descriptive study, using an online survey that was available in French and English. SETTING: Quebec. PARTICIPANTS: A total of 217 residents enrolled in a family medicine program. MAIN OUTCOME MEASURES: Residents' demographic characteristics; the DRE teaching they received throughout their medical training; their reasons for omitting DRE; their recognition of DRE indications (strong vs weak) and application of DRE for 10 anorectal complaints; and their perceptions of the overall quality of the DRE training they received. RESULTS: Of the 879 residents contacted, 217 (25%) responded to the survey. Throughout their training, one-third of respondents did not receive any supervision for or feedback on DRE technique. Seventy-one percent of respondents expressed their inability to identify the nature of abnormal examination findings at least once during their training. The most frequently reported reasons to omit DRE were patient refusal, inadequate setting, and lack of time. CONCLUSION: Most of the residents in this study had omitted DRE at least once in their clinical work despite recognizing its importance. There was discordance between recognition of a complaint requiring DRE and execution of this technique in a clinical setting. Family medicine education programs and continuing medical education committees should consider including DRE training.

BACKGROUND: Transanal endoscopic microsurgery (TEM) for the excision of rectal tumor is mostly performed as an inpatient procedure. The aim of this study was to assess the feasibility and safety of TEM resection as an outpatient procedure in selected patients. POPULATION: All first 178 consecutive patients who underwent resection of a rectal tumor using TEM in our institution from April 2011 to September 2013 were included. METHOD: Standardized retrospective chart review was performed. Primary outcome was 30-day mortality and morbidity. Secondary outcomes included unplanned admission and readmission rates, operative and pathologic data. RESULTS: Of the 175 patients who underwent only TEM, 80% (140/175) were discharged the same day of surgery. There was no mortality. Morbidity rate was 31.4%. Ninety-one percent of 154 patients planned as outpatients were discharged the same day. The most common reason for unplanned admission was urinary retention (7/14; 50%). Twelve patients discharged the day of the procedure were readmitted at 30 days. Median operative time was 60 min (10-256 min). All lesions were removed with grossly negative margins with 15 positive microscopic margins on final pathology. A total of 124 adenomatous polyps and 37 malignant lesions were excised. Mean tumor diameter after fixation was 5.0 cm (range 0.5-11 cm). CONCLUSION: Transanal endoscopic microsurgery as an outpatient procedure is feasible and safe in selected patients. The main reason for unplanned admission was urinary retention in our series.

BACKGROUND: Self-expanding metal stents (SEMS) are increasingly used in the treatment of malignant large bowel obstruction in the setting of inoperable colorectal cancer. Perforation is a well-known complication associated with these devices. The addition of the vascular endothelial growth factor inhibitor bevacizumab is suspected to increase the rate, but the extent of the increase is not known. METHODS: We retrospectively reviewed the records of patients receiving SEMS in tertiary hospitals in Calgary, Alta., between October 2001 and January 2012. RESULTS: We reviewed the records of 87 patients with inoperable colorectal cancer who received SEMS during our study period. Nine perforations occurred in total: 4 of 30 (13%) patients who received no chemotherapy, 3 of 47 (6%) who received chemotherapy but no bevacizumab, and 2 of 10 (20%) who received chemotherapy and bevacizumab. These two patients received bevacizumab with FOLFIRI after SEMS placement, and they had peritoneal disease. CONCLUSION: Our case series and other studies suggest that bevacizumab may increase the risk of colonic perforation in the setting of SEMS. Caution should be used when combining these therapies.
CONTEXTE: Les endoprothèses métalliques auto-expansibles (EMAE) sont de plus en plus utilisées pour le traitement de l'obstruction colique d'origine maligne dans le contexte d'un cancer colorectal inopérable. La perforation est une complication bien connue de ces dispositifs et on soupçonne que l'ajout de l'inhibiteur du facteur de croissance de l'endothélium vasculaire bevacizumab en accroît le taux, mais l'ampleur de cette augmentation est inconnue. MÉTHODES: Nous avons passé en revue de manière rétrospective les dossiers de patients traités par EMAE dans des hôpitaux de soins tertiaires de Calgary, en Alberta, entre octobre 2001 et janvier 2012. RÉSULTANTS: Nous avons examiné les dossiers de 87 patients atteints d'un cancer colorectal inopérable ayant reçu une EMAE durant la période de notre étude. En tout, 9 perforations ont été enregistrées, soit chez 4 patients sur 30 (13 %) qui n'avaient pas reçu de chimiothérapie, chez 3 patients sur 47 (6 %) traités par chimiothérapie sans bevacizumab et chez 2 patients sur 10 (20 %) ayant reçu une chimiothérapie et du bevacizumab. Ces 2 patients avaient été traités par bevacizumab avec FOLFIRI après la pose de l'EMAE et présentaient une atteinte péritonéale. CONCLUSION: Selon notre série de cas et d'autres études, le bevacizumab pourrait accroître le risque de perforation du côlon dans le contexte de l'EMAE. La prudence s'impose lorsqu'on utilise ces traitements concomitamment.

BACKGROUND: Turnbull-Cutait abdominoperineal pull-through followed by delayed coloanal anastomosis (DCA) was first described in 1961. Studies have described its use for challenging colorectal conditions. We reviewed our experience with Turnbull-Cutait DCA as a salvage procedure for complex failure of colorectal anastomosis. METHODS: We performed a retrospective cohort study from October 2010 to September 2011, with analysis of postoperative morbidity and mortality. RESULTS: Seven DCAs were performed for anastomotic complications (3 chronic leaks, 2 rectovaginal fistulas, 1 colovesical fistula, 1 colonic ischemia) following surgery for rectal cancer. Six patients had a diverting ileostomy constructed as part of previous treatment for anastomotic complications before the salvage procedure. No anastomotic leaks were observed. All procedures but 1 were completed successfully. One patient who underwent DCA subsequently required an abdominoperineal resection and a permanent colostomy for postoperative extensive colonic ischemia. No 30-day mortality occurred. CONCLUSION: Salvage Turnbull-Cutait DCA appears to be a safe procedure and could be offered to patients with complex anastomotic complications. This procedure could be added to the surgeon's armamentarium as an alternative to the creation of a permanent stoma.
CONTEXTE: La résection colique abdominale avec extraction trans-anale et anastomose colo-anale différée (CAD) fut décrite initialement par Turnbull et Cutait en 1961. Cette intervention a récemment été rapportée pour le traitement des conditions colorectales complexes. Nous avons revu notre expérience avec la CAD comme chirurgie de sauvetage dans le traitement des complications complexes de l'anastomose colo-anale de première intention. MÉTHODES: Nous avons effectué une étude de cohorte rétrospective entre octobre 2010 et septembre 2011, en analysant la morbidité et la mortalité postopératoires. RÉSULTATS: Sept CAD ont été réalisées en raison de complications anastomotiques (3 fuites anastomotiques chroniques, 2 fistules rectovaginales, 1 fistule colovésicale, 1 ischémie colique) résultant du traitement chirurgical d'un cancer rectal. Six patients avaient subi une iléostomie de dérivation pour fuite anastomotique, dans la période précédant la CAD de sauvetage. À l'exception d'un patient, toutes les procédures se sont soldées en succès. Aucune fuite anastomotique n'a été observée après CAD. Un patient a dû subir une résection abdominopérinéale avec colostomie terminale permanente en raison d'ischémie colique aigue du colon distal après CAD. Aucun décès n'est survenu dans les 30 jours suivant la CAD. CONCLUSION: La CAD de sauvetage apparait comme une intervention sécuritaire qui représente une option thérapeutique valable pour les patients souffrant de complications complexes de fuites anastomotiques colorectales. Cette intervention pourrait s'ajouter à l'arsenal du chirurgien comme alternative à la création d'une stomie permanente.
