Turnbull-Cutait pull-through coloanal anastomosis versus standard coloanal anastomosis plus diverting ileostomy for low anterior resection: a meta-analysis and systematic review.

PURPOSE: Coloanal anastomosis with loop diverting ileostomy (CAA) is an option for low anterior resection of the rectum, and Turnbull-Cutait coloanal anastomosis (TCA) regained popularity in the effort to offer patients a reconstructive option. In this context, we aimed to compare both techniques. METHODS: PubMed, Cochrane, and Scopus were searched for studies published until January 2024. Odds ratios (RRs) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p-values inferior to 0.10 and I2 >25% considered significant. Statistical analysis was conducted in RStudio version 4.1.2 (R Foundation for Statistical Computing). Registered number CRD42024509963. RESULTS: One randomized controlled trial and nine observational studies were included, comprising 1,743 patients, of whom 899 (51.5%) were submitted to TCA and 844 (48.5%) to CAA. Most patients had rectal cancer (52.2%), followed by megacolon secondary to Chagas disease (32.5%). TCA was associated with increased colon ischemia (OR 3.54; 95% CI 1.13 to 11.14; p < 0.031; I2 = 0%). There were no differences in postoperative complications classified as Clavien-Dindo ≥ IIIb, anastomotic leak, pelvic abscess, intestinal obstruction, bleeding, permanent stoma, or anastomotic stricture. In subgroup analysis of patients with cancer, TCA was associated with a reduction in anastomotic leak (OR 0.55; 95% CI 0.31 to 0.97 p = 0.04; I2 = 34%). CONCLUSION: TCA was associated with a decrease in anastomotic leak rate in subgroups analysis of patients with cancer.

Hemorrhagic shock secondary to ruptured hypogastric artery pseudoaneurysm. A rare complication of colorectal anastomotic leakage.

Massive bleeding due to rupture of hypogastric artery pseudoaneurysm is an exceptional complication of colorectal anastomotic leakage. A 41-year-old woman with history of rectal cancer surgery, who debuted with massive rectorrhagia and hypovolemic shock due to rupture of a hypogastric artery pseudoaneurysm as a late complication of a colorectal anastomosis leak. The ruptured hypogastric artery pseudoaneurysm should be taken into account in the differential diagnosis of patients with massive rectorrhagia and history of colorectal anastomosis leak. Endovascular embolization is considered the first-line treatment.

La hemorragia masiva por rotura de un pseudoaneurisma de la arteria hipogástrica es una complicación muy rara de la fuga anastomótica colorrectal. Mujer de 41 años con antecedentes de cirugía por cáncer de recto, que debutó con un cuadro de rectorragias masivo y shock hipovolémico secundario a la rotura de un pseudoaneurisma de la arteria hipogástrica como complicación tardía de una fuga de la anastomosis colorrectal. La rotura de un pseudoaneurisma de la arteria hipogástrica se debe tener presente en el diagnostico diferencial de pacientes con rectorragia masiva y antecedentes de dehiscencia de anastomosis colorrectal. La embolización endovascular es actualmente el tratamiento de elección.

Controversies in IPAA for Ulcerative Colitis: A Systematic Review of Different Anastomotic Techniques.

BACKGROUND: Available techniques for IPAA in ulcerative colitis include handsewn, double-stapled, and single-stapled anastomoses. There are controversies, indications, and different outcomes regarding these techniques. OBJECTIVE: To describe technical details, indications, and outcomes of 3 specific types of anastomoses in restorative proctocolectomy. DATA SOURCE: Systematic literature review for articles in the PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. STUDY SELECTION: Studies describing outcomes of the 3 different types of anastomoses, during pouch surgery, in patients undergoing restorative proctocolectomy for ulcerative colitis. INTERVENTION: IPAA technique. MAIN OUTCOME MEASURES: Postoperative outcomes (anastomotic leaks, overall complication rates, and pouch function). RESULTS: Twenty-one studies were initially included: 6 studies exclusively on single-stapled IPAA, 2 exclusively on double-stapled IPAA, 6 studies comparing single-stapled to double-stapled techniques, 6 comparing double-stapled to handsewn IPAA, and 1 comprising single-stapled to handsewn IPAA. Thirty-seven studies were added according to authors' discretion as complementary evidence. Between 1990 and 2015, most studies were related to double-stapled IPAA, either only analyzing the results of this technique or comparing it with the handsewn technique. Studies published after 2015 were mostly related to transanal approaches to proctectomy for IPAA, in which a single-stapled anastomosis was introduced instead of the double-stapled anastomosis, with some studies comparing both techniques. LIMITATIONS: A low number of studies with handsewn IPAA technique and a large number of studies added at authors' discretion were the limitations of this strudy. CONCLUSIONS: Handsewn IPAA should be considered if a mucosectomy is performed for dysplasia or cancer in the low rectum or, possibly, for re-do surgery. Double-stapled IPAA has been more widely adopted for its simplicity and for the advantage of preserving the anal transition zone, having lower complications, and having adequate pouch function. The single-stapled IPAA offers a more natural design, is feasible, and is associated with reasonable outcomes compared to double-stapled anastomosis. See video from symposium.

Bowel preparation for elective colectomy in Crohn's disease: results from a global cohort study using the NSQIP database.

AIM: The role of bowel preparation before colectomy in Crohn's disease patients remains controversial. This retrospective analysis of a prospective cohort study aimed to investigate the clinical outcomes associated with mechanical and antibiotic colon preparation in patients diagnosed with Crohn's disease undergoing elective colectomy. METHOD: Data were collected from the American College of Surgeons National Surgical Quality Improvement Program participant user files from 2016 to 2021. A total of 6244 patients with Crohn's disease who underwent elective colectomy were included. The patients were categorized into two groups: those who received combined colon preparation (mechanical and antibiotic) and those who did not receive any form of bowel preparation. The primary outcomes assessed were the rate of anastomotic leak and the occurrence of deep organ infection. Secondary outcomes included all-cause short-term mortality, clinical-related morbidity, ostomy creation, unplanned reoperation, operative time, hospital length of stay and ileus. RESULTS: Combined colon preparation was associated with significantly reduced risks of anastomotic leak (relative risk 0.73, 95% CI 0.56-0.95, P = 0.021) and deep organ infection (relative risk 0.68, 95% CI 0.56-0.83, P < 0.001). Additionally, patients who underwent colon preparation had lower rates of ostomy creation, shorter hospital stays and a decreased incidence of ileus. However, there was no significant difference in all-cause short-term mortality or the need for unplanned reoperation between the two groups. CONCLUSION: This study shows that mechanical and antibiotic colon preparation may have clinical benefits for patients with Crohn's disease undergoing elective colectomy.

Application of the REAL-score prognostic index in decision making in rectal cancer surgery.

BACKGROUND: Colorectal anastomosis leak (AL) is the most feared complication of rectal cancer surgery (1-19%) as it increases morbidity and mortality and worsens oncological outcomes in terms of local recurrence and survival. The publication of the REAL-score index makes it possible to predict the risk of AL and compare the expected results with those obtained. METHOD: Observational, descriptive, longitudinal and retrospective study of patients operated on for rectal cancer at the Miguel Servet University Hospital, in Zaragoza, Spain, in 2019. Statistical analysis of morbidity and mortality outcome variables and the REAL-score index using ROC curves. RESULTS: Of 80 patients operated on for rectal cancer, colorectal anastomosis was performed in 52 and temporary ileostomy in 11 (21.2%). Morbidity was high (38.4%), but severe only in 7.7% (Clavien-Dindo IIIb), with no deaths. There were four dehiscences: one type B and three type C. A direct relationship between high risk of AL and the practice of temporary stoma is observed when the cut-off point of the REAL-score exceeds 14.74%. CONCLUSIONS: REAL-score can help in decision-making in rectal cancer surgery. Above a cut-off point, the risk of AL would imply a selective ileostomy.

ANTECEDENTES: La dehiscencia de la anastomosis colorrectal (DA) es la complicación más temida de la cirugía del cáncer de recto (1-19%), pues incrementa la morbimortalidad y empeora los resultados oncológicos en términos de recidiva local y supervivencia. La publicación del índice REAL-score permite predecir el riesgo de DA y comparar los resultados esperados con los obtenidos. MÉTODO: Estudio observacional, descriptivo, longitudinal y retrospectivo, de pacientes intervenidos de cáncer de recto en el Hospital Universitario Miguel Servet, en Zaragoza, España, en 2019. Análisis estadístico de variables resultado de morbimortalidad y del índice REAL-score mediante curvas ROC. RESULTADOS: De 80 pacientes intervenidos de cáncer de recto, se realizó anastomosis colorrectal en 52 e ileostomía temporal en 11 (21.2%). La morbilidad fue alta (38.4%), pero grave solo en el 7.7% (Clavien-Dindo IIIb), sin ningún fallecimiento. Hubo cuatro dehiscencias: una de tipo B y tres de tipo C. Se observa una relación directa entre alto riesgo de DA y la práctica de estoma temporal cuando el punto de corte del REAL-score supera el 14.74%. CONCLUSIONES: El REAL-score puede ayudar en la toma de decisiones en la cirugía del cáncer de recto. Por encima de un punto de corte, el riesgo de DA implicaría ileostomía selectiva.

Sigmoid resection and primary anastomosis for perforated diverticulitis with peritonitis: To divert or not to divert-A systematic review and meta-analysis.

BACKGROUND: The role of proximal diversion in patients undergoing sigmoid resection and primary anastomosis for diverticulitis with generalized peritonitis is unclear. The aim of this study was to compare the clinical outcomes of sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with a proximal diversion in perforated diverticulitis with diffuse peritonitis. METHOD: A systematic literature search on sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with proximal diversion for diverticulitis with diffuse peritonitis was conducted in the Medline and EMBASE databases. Randomized clinical trials and observational studies reporting the primary outcome of interest (30-day mortality) were included. Secondary outcomes were major morbidity, anastomotic leak, reoperation, stoma nonreversal rates, and length of hospital stay. A meta-analysis of proportions and linear regression models were used to assess the effect of each procedure on the different outcomes. RESULTS: A total of 17 studies involving 544 patients (sigmoid resection and primary anastomosis: 287 versus sigmoid resection and primary anastomosis with proximal diversion: 257) were included. Thirty-day mortality (odds ratio 1.12, 95% confidence interval 0.53-2.40, P = .76), major morbidity (odds ratio 1.40, 95% confidence interval 0.80-2.44, P = .24), anastomotic leak (odds ratio 0.34, 95% confidence interval 0.099-1.20, P = .10), reoperation (odds ratio 0.49, 95% confidence interval 0.17-1.46, P = .20), and length of stay (sigmoid resection and primary anastomosis: 12.1 vs resection and primary anastomosis with diverting ileostomy: 15 days, P = .44) were similar between groups. The risk of definitive stoma was significantly lower after sigmoid resection and primary anastomosis (odds ratio 0.05, 95% confidence interval 0.006-0.35, P = .003). CONCLUSION: Sigmoid resection and primary anastomosis with or without proximal diversion have similar postoperative outcomes in selected patients with diverticulitis and diffuse peritonitis. However, further randomized controlled trials are needed to confirm these results.

Tube-in-tube endoscopic vacuum therapy for treatment of colorectal anastomotic leaks: A low-cost, patient-friendly, feasible and efficient technical modification of sponge-based endoscopic vacuum therapy.

BACKGROUND AND AIMS: Colorectal endoscopic vacuum therapy (CR EVT) is usually performed using sponges passed through the anus. It may be associated with patient discomfort and displacement of the aspiration tube. METHODS: With the tube-in-tube endoscopic vacuum therapy modification (CR TT-EVT), it is possible to position the aspiration tube in the pelvic cavity through the abdominal wall. In addition, it allows frequent cleaning of the fistula, eliminates the need for programmed device changes, and enables a standardized approach to such a wide variety of fistulas, leaks, and perforations. RESULTS: Here is a technical note on how to perform CR TT-EVT, while we are at the early phase of our case series we have reached 100% of technical success.

Choosing the best endoscopic approach for post-bariatric surgical leaks and fistulas: Basic principles and recommendations.

Post-surgical leaks and fistulas are the most feared complication of bariatric surgery. They have become more common in clinical practice given the increasing number of these procedures and can be very difficult to treat. These two related conditions must be distinguished and characterized to guide the appropriate treatment. Leak is defined as a transmural defect with communication between the intra and extraluminal compartments, while fistula is defined as an abnormal communication between two epithelialized surfaces. Traditionally, surgical treatment was the preferred approach for leaks and fistulas and was associated with high morbidity with significant mortality rates. However, with the development of novel devices and techniques, endoscopic therapy plays an increasingly essential role in managing these conditions. Early diagnosis and endoscopic therapy initiation after clinical stabilization are crucial to success since clinical success rates are higher for acute leaks and fistulas when compared to late and chronic leaks and fistulas. Several endoscopic techniques are available with different mechanisms of action, including direct closure, covering/diverting or draining. The treatment should be individualized by considering the characteristics of both the patient and the defect. Although there is a lack of high-quality studies to provide standardized treatment algorithms, this narrative review aims to provide a summary of the current scientific evidence and, based on this data and our extensive experience, make recommendations to help choose the best endoscopic approach for the management of post-bariatric surgical leaks and fistulas.

Preoperative risk factors associated with anastomotic leakage after colectomy for colorectal cancer: a systematic review and meta-analysis.

INTRODUCTION: anastomotic leak (AL) after colectomy for colorectal cancer (CRC) is a life-threatening complication. This systematic review and meta-analysis aimed to evaluate the preoperative risk factors for AL in patients submitted to colectomy. METHODS: the bibliographic search covered 15 years and 9 months, from 1st January 2005 to 19th October 2020 and was performed using PubMed, Cochrane Library, Scopus, Biblioteca Virtual em Saúde, Europe PMC and Web of Science databases. The inclusion criteria were cross-sectional, cohort and case-control studies on preoperative risk factors for AL (outcome). The Newcastle-Ottawa scale was used for bias assessment within studies. Meta-analysis involved the calculation of treatment effects for each individual study including odds ratio (OR), relative risk (RR) and 95% confidence intervals (95% CI) with construction of a random-effects model to evaluate the impact of each variable on the outcome. Statistical significance was set at p<0.05. RESULTS: cross-sectional studies were represented by 39 articles, cohort studies by 21 articles and case-control by 4 articles. Meta-analysis identified 14 main risk factors for AL in CRC patients after colectomy, namely male sex (RR=1.56; 95% CI=1.40-1.75), smoking (RR=1.48; 95% CI=1.30-1.69), alcohol consumption (RR=1.35; 95% CI=1.21-1.52), diabetes mellitus (RR=1.97; 95% CI=1.44-2.70), lung diseases (RR=2.14; 95% CI=1.21-3.78), chronic obstructive pulmonary disease (RR=1.10; 95% IC=1.04-1.16), coronary artery disease (RR=1.61; 95% CI=1.07-2.41), chronic kidney disease (RR=1.34; 95% CI=1.22-1.47), high ASA grades (RR=1.70; 95% CI=1.37-2.09), previous abdominal surgery (RR=1.30; 95% CI=1.04-1.64), CRC-related emergency surgery (RR=1.61; 95% CI=1.26-2.07), neoadjuvant chemotherapy (RR=2.16; 95% CI=1.17-4.02), radiotherapy (RR=2.36; 95% CI=1.33-4.19) and chemoradiotherapy (RR=1.58; 95% CI=1.06-2.35). CONCLUSIONS: important preoperative risk factors for colorectal AL in CRC patients have been identified based on best evidence-based research, and such knowledge should influence decisions regarding treatment.

Endoscopic Vacuum Therapy (EVT) for the Treatment of Post-Bariatric Surgery Leaks and Fistulas: a Systematic Review and Meta-analysis.

Bariatric surgery remains the most effective treatment for morbid obesity and its comorbidities. However, post-surgical leaks and fistulas can occur in about 1-5% of patients, with challenging treatment approaches. Endoscopic vacuum therapy (EVT) has emerged as a promising tool due to its satisfactory results and accessibility. In this first systematic review and meta-analysis on the subject, EVT revealed rates of 87.2% clinical success, 6% moderate adverse events, and 12.5% system dislodgements, requiring 6.47 EVT system exchanges every 4.39 days, with a dwell time of 25.67 days and a total length of hospitalization of 44.43 days. Although our results show that EVT is a safe and effective therapy for post-surgical leaks and fistulas, they should be interpreted with caution due to the paucity of available data.

Transthoracic Esophagectomy: Hand-sewn Versus Side-to-side Linear-stapled Versus Circular-stapled Anastomosis: A Systematic Review and Meta-analysis.

BACKGROUND: Three anastomotic techniques are mostly used to create an esophagogastric anastomosis in a transthoracic esophagectomy: hand-sewn (HS), side-to-side linear-stapled (SSLS), and circular-stapled (CS). The aim of this study was to compare surgical outcomes after HS, SSLS, and CS intrathoracic esophagogastric anastomosis. MATERIALS AND METHODS: A systematic review using the MEDLINE database was performed to identify original articles analyzing outcomes after HS, SSLS, and CS esophagogastric anastomosis. The main outcome was an anastomotic leakage rate. Secondary outcomes included overall morbidity, major morbidity, and mortality. A meta-analysis of proportions and linear regression models were used to assess the effect of each anastomotic technique on the different outcomes. RESULTS: A total of 101 studies comprising 12,595 patients were included; 8835 (70.1%) with CS, 2532 (20.1%) with HS, and 1228 (9.8%) with SSLS anastomosis. Anastomotic leak occurred in 10% [95% confidence interval (CI), 6%-15%], 9% (95% CI, 6%-13%), and 6% (95% CI, 5%-7%) of patients after HS, SSLS, and CS anastomosis, respectively. Risk of anastomotic leakage was significantly higher with HS anastomosis (odds ratio=1.73, 95% CI: 1.47-2.03, P<0.0001) and SSLS (odds ratio=1.68, 95% CI: 1.36-2.08, P<0.0001), as compared with CS. Overall morbidity (HS: 52% vs. SLSS: 39% vs. CS: 35%) and major morbidity (HS: 33% vs. CS: 19%) rates were significantly lower with CS anastomosis. Mortality rate was 4% (95% CI, 3%-6%), 2% (95% CI, 2%-3%), and 3% (95% CI, 3%-4%) after HS, SSLS, and CS anastomosis, respectively. CONCLUSION: HS and SSLS intrathoracic esophagogastric anastomoses are associated with significantly higher rates of an anastomotic leak than CS anastomosis.

Predictors of anastomotic leak after total gastrectomy in patients with adenocarcinoma.

BACKGROUND: Esophagojejunal anastomotic leakage (EJAL) is among the most feared complications after gastric cancer surgery; they entail an uncertain prognosis and relate with increased morbidity and mortality. Factors associated with their development are not well determined, and their diagnosis and treatment vary between institutions. MATERIAL AND METHODS: Retrospective case-control study of patients operated of total gastrectomy with Roux-en-Y esophagojejunostomy from January 2002 to December 2018. We divided our sample into two groups based on the presence of EJAL, and compared demographic, clinical, and histologic variables. We performed a logistic regression model to search risk factors associated with EJAL and described the management offered in our center. RESULTS: We included 58 patients of which 8 (13.7%) presented clinically relevant EJAL. On the comparative analysis, albumin levels and diffuse histology presented a statistically significant difference between groups and presented association with EJAL in the logistic regression model. Regarding treatment of EJAL, ten patients (55.5%) required only conservative measures, whereas eight patients (44.4%) warranted an endoscopic or surgical intervention. CONCLUSION: Our retrospective analysis identified some factors that may be associated with the development of EJAL after gastric cancer surgery. High suspicion and prompt identification of this complication is essential to improve postoperative outcomes in this group.

INTRODUCCIÓN: Las fugas de la anastomosis esófago-yeyunal se encuentran entre las más temidas complicaciones de la cirugía para cáncer gástrico. Estas conllevan un mal pronóstico con una alta mortalidad y morbilidad. Los factores asociados a su desarrollo no están bien determinados y su diagnóstico, y tratamiento varían ampliamente entre instituciones. MATERIAL Y MÉTODOS: Estudio retrospectivo de casos y controles en pacientes operados de gastrectomía total con esófago-yeyuno anastomosis en Y de Roux en el periodo de enero 2002 a diciembre 2018. Nuestra muestra fue dividida en dos grupos con base al desarrollo de fuga de anastomosis en el postoperatorio. Se realizó un análisis comparativo de características demográficas, clínicas y histológicas. Se realizó además una regresión logística para identificar factores de riesgo asociados al desarrollo de fuga de anastomosis en nuestra serie. RESULTADOS: Incluimos a 58 pacientes de los cuales 8 (13.7%) presentaron fuga de anastomosis clínicamente relevante. En el estudio comparativo: Niveles disminuidos de albúmina e histología difusa fueron significativamente mayores en el grupo de fuga y se asociaron en el modelo de regresión logística. En cuanto al tratamiento, diez pacientes (55%) requirieron únicamente tratamiento conservador, mientras que ocho pacientes (44.4%) fueron sometidos a maniobras endoscópicas o quirúrgicas. CONCLUSIÓN: Nuestro análisis retrospectivo identifico factores asociados al desarrollo de fuga de anastomosis posterior a cirugía de cáncer gástrico. Una alta sospecha diagnóstica es esencial para mejorar el pronóstico de estos pacientes.

Open versus hybrid versus totally minimally invasive Ivor Lewis esophagectomy: Systematic review and meta-analysis.

BACKGROUND: Hybrid and minimally invasive approaches have emerged as less invasive alternatives to open Ivor Lewis esophagectomy. The aim of this study was to compare surgical outcomes between open (OE), hybrid (HE), and totally minimally invasive esophagectomy (TMIE). METHODS: A systematic literature search was performed to analyze outcomes after OE, HE, and TMIE with intrathoracic anastomosis. Main outcomes included anastomotic leak rate, overall morbidity, and 30-day mortality. A meta-analysis of proportions was used to assess the effect of each approach on different outcomes. RESULTS: A total of 130 studies comprising 16,053 patients were included for analysis; 8081 (50.3%) underwent OE, 1524 (9.5%) HE, and 6448 (40.2%) TMIE. The risk of anastomotic leak was lower after OE (odds ratio [OR], 0.71; 95% CI, 0.62-0.81; P < .0001). Overall morbidity rate was 45% (95% CI, 38%-52%) after OE, 40% (95% CI, 25%-59%) after HE, and 37% (95% CI, 32%-43%) after TMIE. Risk estimation showed higher odds of postoperative mortality after OE (OR, 2.22; 95% CI, 1.76-2.81; P < .0001) and HE (OR, 1.93; 95% CI, 1.32-2.81; P < .001), compared with TMIE. Median length of hospital stay (LOS) was 14.1 (range, 8-28), 12.5 (range, 8-18), and 11.9 (range, 7-30) days after OE, HE and TMIE, respectively (P = .003). CONCLUSIONS: HE and TMIE are associated with lower rates of overall morbidity, reduced postoperative mortality, and shorter LOS, compared with OE. TMIE is associated with lower mortality rates and shorter LOS than HE. Further efforts are needed to widely embrace TMIE in a safe manner.

Risk factors associated to intestinal anastomotic leakage in elective surgery.

BACKGROUND: The intestinal anastomotic leakage is the most feared surgical complication of a digestive surgery and is associated with a significant increase of morbidity, mortality and hospital stay. OBJECTIVE: Analyze the risk factors to the intestinal anastomotic leakage in elective surgery. METHOD: Observational and retrospective study in which we include patients with intestinal anastomosis, in elective surgery at the second level hospital from January 2007 to January 2017. RESULTS: 64 patients were included in the study, in which 7 presented anastomotic leakage. The statistically significant risk factors associated with anastomotic leakage were, cocaine use (p = 0.030), neoplasia as a primary pathology (p = 0.008), neoadjuvant treatment for neoplasia (p = 0.003), and end-to-end anastomosis (p = 0.037). Patients with a leakage had a longer hospital stay and a mortality of 14.3%. CONCLUSIONS: The risk factors associated with the presence of anastomotic leakage found in this study are consistent with the reported worldwide literature. However, in our results, it is worth highlighting the use of cocaine as a risk factor, with statistical significance.

ANTECEDENTES: La fuga de una anastomosis intestinal es la complicación quirúrgica más temida de la cirugía digestiva y se asocia con un aumento significativo de la morbimortalidad y de la estancia hospitalaria. OBJETIVO: Analizar los factores de riesgo asociados a la fuga de anastomosis intestinal en cirugía electiva. MÉTODO: Estudio observacional y retrospectivo en el que se recabaron los expedientes de los pacientes operados de anastomosis intestinal en forma electiva en un hospital de segundo nivel de enero de 2007 a enero de 2017. RESULTADOS: Se incluyeron 64 pacientes, de los cuales siete presentaron fuga de la anastomosis. Los factores de riesgo asociados a fuga anastomótica estadísticamente significativos fueron consumo de cocaína (p = 0.030), neoplasia como patología primaria (p = 0.008), tratamiento con neoadyuvantes para neoplasia (p = 0.003) y anastomosis término-terminal (p = 0.037). Los pacientes con fuga tuvieron una estancia intrahospitalaria más prolongada y una mortalidad del 14.3%. CONCLUSIONES: Los factores de riesgo asociados con la presencia de fuga anastomótica encontrados en este estudio son consistentes con los reportados en la literatura mundial. Sin embargo, en nuestros resultados cabe destacar el uso de cocaína como factor de riesgo, con significancia estadística.

"Relaparoscopy" to treat early complications following colorectal surgery.

BACKGROUND: Laparoscopic surgery has shown clear benefits that could also be useful in the emergency setting such as early reoperations after colorectal surgery. The aim of this study was to evaluate the safety and feasibility of laparoscopic reintervention ("relaparoscopy") (RL) to manage postoperative complications after laparoscopic colorectal surgery. METHODS: We performed a retrospective study based on a prospectively collected database from 2000 to 2019. Patients who required a reoperation after undergoing laparoscopic colorectal surgery were included. According to the approach used at the reoperation, the cohort was divided in laparoscopy (RL) and laparotomy (LPM). Demographics, hospital stay, morbidity, and mortality were analyzed. RESULTS: A total of 159 patients underwent a reoperation after a laparoscopic colorectal surgery: 124 (78%) had RL and 35 (22%) LPM. Demographics were similar in both groups. Patients who underwent left colectomy were more frequently reoperated by laparoscopy (RL: 42.7% vs. LPM: 22.8%, p: 0.03). The most common finding at the reoperation was anastomotic leakage, which was treated more often by RL (RL: 67.7% vs. LPM: 25.7%, p: 0.0001), and the most common strategy was drainage and loop ileostomy (RL: 65.8% vs. LPM: 17.6%, p: 0.00001). Conversion was necessary in 12 patients (9.6%). Overall morbidity rate was 52.2%. Patients in the RL group had less postoperative severe complications (RL: 12.1% vs. LPM: 22.8, p: 0.01). Mortality rate was similar in both groups. CONCLUSION: Relaparoscopy is feasible and safe for treating early postoperative complications, particularly anastomotic leakage after left colectomy.

Surgical outcomes after totally minimally invasive Ivor Lewis esophagectomy. A systematic review and meta-analysis.

BACKGROUND: A transthoracic esophagectomy is associated with high rates of morbidity. Minimally invasive esophagectomy has emerged to decrease such morbidity. The aim of this study was to accurately determine surgical outcomes after totally minimally invasive Ivor-Lewis Esophagectomy (TMIE). METHODS: A systematic literature search was performed to identify original articles analyzing patients who underwent TMIE. Main outcomes included overall morbidity, major morbidity, pneumonia, arrhythmia, anastomotic leak, chyle leak, and mortality. A meta-analysis was conducted to estimate the overall weighted proportion and its 95% confidence interval (CI) for each analyzed outcome. RESULTS: A total of 5619 patients were included for analysis; 4781 (85.1%) underwent a laparoscopic/thoracoscopic esophagectomy and 838 (14.9%) a robotic-assisted esophagectomy. Mean age of patients was 63.5 (55-67) years and 75.8% were male. Overall morbidity and major morbidity rates were 39% (95% CI, 33%-45%) and 20% (95% CI, 13%-28%), respectively. Postoperative pneumonia and arrhythmia rates were 10% (95% CI, 8%-13%) and 12% (95% CI, 8%-17%), respectively. Anastomotic leak rate across studies was 8% (95% CI, 6%-10%). Chyle leak rate was 3% (95% CI, 2%-5%). Mortality rate was 2% (95% CI, 2%-2%). Median ICU stay and length of hospital stay were 2 (1-4) and 11.2 (7-20) days, respectively. CONCLUSIONS: Totally minimally invasive Ivor-Lewis esophagectomy is a challenging procedure with high morbidity rates. Strategies to enhance postoperative outcomes after this operation are still needed.

Indocyanine green (ICG) fluorescence imaging for prevention of anastomotic leak in totally minimally invasive Ivor Lewis esophagectomy: a systematic review and meta-analysis.

BACKGROUND: Indocyanine green (ICG) fluorescence imaging is an emerging technology that might help decreasing anastomotic leakage (AL) rates. The aim of this study was to determine the usefulness of ICG fluorescence imaging for the prevention of AL after minimally invasive esophagectomy with intrathoracic anastomosis. METHODS: A systematic literature review of the MEDLINE and Cochrane databases was performed to identify all articles on totally minimally invasive Ivor Lewis esophagectomy. Studies were then divided into two groups based on the use or not of ICG for perfusion assessment. Primary outcome was anastomotic leak. Secondary outcomes included operative time, ICG-related adverse reactions, and mortality rate. A meta-analysis was conducted to estimate the overall weighted proportion and its 95% confidence interval (CI) for main outcomes. RESULTS: A total of 3,171 patients were included for analysis: 381 (12%) with intraoperative ICG fluorescence imaging and 2,790 (88%) without ICG. Mean patients' age and proportion of males were similar between groups. Mean operative time was also similar between both groups (ICG: 354.8 vs. No-ICG: 354.1 minutes, P = 0.52). Mean ICG dose was 12 mg (5-21 mg). No ICG-related adverse reactions were reported. AL rate was 9% (95% CI, 5-17%) and 9% (95% CI, 7-12%) in the ICG and No-ICG groups, respectively. The risk of AL was similar between groups (odds ratio 0.85, 95% CI 0.53-1.28, P = 0.45). Mortality was 3% (95% CI, 1-9%) in patients with ICG and 2% (95% CI, 2-3%) in those without ICG. Median length of hospital stay was also similar between groups (ICG: 13.6 vs. No-ICG: 11.2 days, P = 0.29). CONCLUSION: The use of ICG fluorescence imaging for perfusion assessment does not seem to reduce AL rates in patients undergoing minimally invasive esophagectomy with intrathoracic anastomosis.
