Abstract
Background: Self-expandable metallic stent (SEMS) was introduced for the treatment of obstructive colorectal cancer (CRC) a few decades ago. However, its long-term outcomes remain controversial, especially for stage IV CRC. The aim of this study was to clarify the outcomes of SEMS as a "bridge to surgery" (BTS) for obstructive and symptomatic primary tumors in stage IV CRC by one-to-one propensity-score matching. Materials and Methods: This retrospective cohort study was conducted at a single center from January 2007 to December 2017. Patients with obstructive and symptomatic primary tumors of stage IV CRC underwent primary resection (PR) or placement of a SEMS as a BTS. They were divided into SEMS and PR groups, and their short- and long-term outcomes were compared. Results: In total, 52 patients were reviewed (SEMS group, 21; PR group, 31). Sixteen patients in both groups were matched using propensity scores. Patients in the SEMS group more frequently underwent laparoscopic surgery than those in the PR group (75% versus 19%, P = .004). The two groups showed no significant differences in perioperative and pathological outcomes. The 5-year overall survival was not significantly different between groups (29% versus 20%, P = .53). Conclusions: As a BTS, the use of SEMS for obstructive and symptomatic primary tumors in CRC stage IV can be a comparable option to PR in terms of short- and long-term outcomes, and would be less invasive with respect to surgical procedures.

Abstract
BACKGROUND The role of laparoscopy for emergency resection of left-sided obstructive colon cancer remains unclear, especially regarding impact on survival. OBJECTIVE This study aimed to determine short- and long-term outcomes after laparoscopic versus open emergency resection of left-sided obstructive colon cancer. DESIGN This observational cohort study compared patients who underwent laparoscopic emergency resection to those who underwent open emergency resection between 2009 and 2016 by using 1:3 propensity-score matching. Matching variables included sex, age, BMI, ASA score, previous abdominal surgery, tumor location, cT4, cM1, multivisceral resection, small-bowel distention on CT, and subtotal colectomy. SETTING This was a nationwide, population-based study. PATIENTS Of 2002 eligible patients with left-sided obstructive colon cancer, 158 patients who underwent laparoscopic emergency resection were matched with 474 patients who underwent open emergency resection. INTERVENTIONS The intervention was laparoscopic versus open emergency resection. MAIN OUTCOME MEASURES The main outcome measures were 90-day mortality, 90-day complications, permanent stoma, disease recurrence, overall survival, and disease-free survival. RESULTS Intentional laparoscopy resulted in significantly fewer 90-day complications (26.6% vs 38.4%; conditional OR, 0.59; 95% CI, 0.39-0.87) and similar 90-day mortality. Laparoscopy resulted in better 3-year overall survival (81.0% vs 69.4%; HR, 0.54; 95% CI, 0.37-0.79) and disease-free survival (68.3% vs 52.3%; HR, 0.64; 95% CI, 0.47-0.87). Multivariable regression analyses of the unmatched 2002 patients confirmed an independent association of laparoscopy with fewer 90-day complications and better 3-year survival. LIMITATIONS Selection bias was the limitation that cannot be completely ruled out because of the retrospective nature of this study. CONCLUSIONS This population-based study with propensity score-matched analysis suggests that intentional laparoscopic emergency resection might improve outcomes in patients with left-sided obstructive colon cancer compared to open emergency resection. Management of those patients in the emergency setting requires proper selection for intentional laparoscopic resection if relevant expertise is available, thereby considering other alternatives to avoid open emergency resection (ie, decompressing stoma).

RESULTADOS A CORTO Y LARGO PLAZO DESPUS DE LA RESECCIN LAPAROSCPICA DE EMERGENCIA EN CNCER DE COLON IZQUIERDO OBSTRUCTIVO UN ANLISIS EMPAREJADO POR PUNTAJE DE PROPENSIN A NIVEL NACIONAL ANTECEDENTES:El papel de la laparoscopia en la resección de emergencia en cáncer de colon izquierdo obstructivo sigue sin estar claro, especialmente con respecto al impacto en la supervivencia.OBJETIVO:El objetivo de este estudio fue determinar los resultados a corto y largo plazo después de la resección de emergencia laparoscópica versus abierta en cáncer de colon izquierdo obstructivo.DISEÑO:Estudio observacional de cohortes comparó pacientes que se sometieron a resección de laparoscópica de emergencia versus resección abierta de emergencia entre 2009 y 2016, mediante el uso de emparejamineto por puntaje de propensión 1: 3. Las variables emparejadas incluyeron sexo, edad, IMC, puntaje ASA, cirugía abdominal previa, ubicación del tumor, cT4, cM1, resección multivisceral, distensión del intestino delgado en la TAC y colectomía subtotal.ENTORNO CLINICO:A nivel nacional, basado en la población.PACIENTES:De 2002 pacientes elegibles con cáncer de colon izquierdo obstructivo, 158 pacientes con resección laparoscópica s de emergencia e emparejaron con 474 pacientes con resección abierta de emergencia.INTERVENCIONES:Resección laparoscópica de emergencia versus abierta.PRINCIPALES MEDIDAS DE RESULTADO:Las medidas primarias fueron la mortalidad a 90 días, complicaciones a 90 días, estoma permanente, recurrencia de la enfermedad, supervivencia general y supervivencia libre de enfermedad.RESULTADOS:La laparoscopia intencional dió como resultado significativamente menos complicaciones a los 90 días (26,6 % vs 38,4 %, cOR 0,59, IC del 95 %: 0,39-0,87) y una mortalidad similar a los 90 días. La laparoscopia resultó en una mejor supervivencia general a los 3 años (81,0 % vs 69,4 %, HR 0,54, IC del 95 % 0,37-0,79) y supervivencia libre de enfermedad (68,3 % vs 52,3 %, HR 0,64, IC del 95 % 0,47-0,87). Los análisis de regresión multivariable de los 2002 pacientes no emparejados confirmaron una asociación independiente de la laparoscopia con menos complicaciones a los 90 días y una mejor supervivencia a los 3 años.LIMITACIONES:El sesgo de selección no se puede descartar por completo debido a la naturaleza retrospectiva de este estudio.CONCLUSIONES:Estudio poblacional con análisis emparejado por puntaje de propensión sugiere que la resección laparoscópica de emergencia intencional podría mejorar los resultados a corto y largo plazo en pacientes con cáncer de colon izquierdo obstructivo en comparación con resección abierta de emergencia, lo que justifica la confirmación en estudios futuros. El manejo de esos pacientes en el entorno de emergencia requiere una selección adecuada para la resección laparoscópica intencional si se dispone de experiencia relevante, considerando así otras alternativas para evitar la resección abierta de emergencia (es decir, ostomia descompresiva).

Abstract
The laparoscopic approaches using the triangular anastomosis technique for sigmoid colon cancer (SCC) are rare. This CONSORT study explored the short-term effects of laparoscopic radical resection of SCC with modified triangular anastomosis technique and laparoscopic-assisted small incision colon cancer reconstruction surgery. From April 2019 to January 2021, a total of 86 patients with SCC who were admitted to Luopu County People's Hospital were selected and received radical resection. Patients were divided into 2 groups using a random number table method: in the control group, patients underwent laparoscopic-assisted small-incision reconstruction surgery, and patients in the observation group underwent complete laparoscopic surgery with modified triangular anastomosis technique. The 2 groups were compared in perioperative related indicators and postoperative complications. After 3 months follow-up, local tumor recurrence and metastasis, abdominal wall puncture and implantation, and death were observed. Compared to the control group, shorter operation time, gastrointestinal reconstruction time, postoperative exhaust time, hospitalization time, and less intraoperative blood loss, and lower probability of complications were observed in the observation group (P < .05). However, there was no significant difference in the number of lymph node dissections between the 2 groups (P > .05). After 3 months of follow-up, no local tumor recurrence, distant tumor metastasis, abdominal wall puncture implantation, and death were found in the 2 groups of patients. It is indicated that the improved triangular anastomosis technique for complete laparoscopic radical resection of SCC is effective in treatment for SCC.

Abstract
BACKGROUND Risk stratification has become a key part of the care processes for patients having emergency bowel surgery. This study aimed to determine if operative approach influences risk-model performance, and risk-adjusted mortality rates in the United Kingdom. METHODS A prospectively planned analysis was conducted using National Emergency Laparotomy Audit (NELA) data from December 2013 to November 2018. The risk-models investigated were P-POSSUM and the NELA Score, with model performance assessed in terms of discrimination and calibration. Risk-adjusted mortality was assessed using Standardised Mortality Ratios (SMR). Analysis was performed for the total cohort, and cases performed open, laparoscopically and converted to open. Sub-analysis was performed for cases with ≤ 20% predicted mortality. RESULTS Data were available for 116 396 patients with P-POSSUM predicted mortality, and 46 935 patients with the NELA score. Both models displayed excellent discrimination with little variation between operative approaches (c-statistic: P-POSSUM 0.801-0.836; NELA Score 0.811-0.862). The NELA score was well calibrated across all deciles of risk, but P-POSSUM over-predicted risk beyond 20% mortality. Calibration plots for operative approach demonstrated that both models increasingly over-predicted mortality for laparoscopy, relative to open and converted to open surgery. SMRs calculated using both models consistently demonstrated that risk-adjusted mortality with laparoscopy was a third lower than open surgery. CONCLUSION Risk-adjusted mortality for emergency bowel surgery is lower for laparoscopy than open surgery, with P-POSSUM and NELA score both over-predicting mortality for laparoscopy. Operative approach should be considered in the development of future risk-models that rely on operative data.

Abstract
BACKGROUND Curative surgery for ulcerative colitis can be subdivided into restorative (with pouch and anastomosis) and non-restorative operations. Restorative surgery in older adults is controversial, due to concerns about surgical risk and long-term functional outcome. The goal of this study is to compare 30-day outcomes for restorative and non-restorative surgery in older adults with ulcerative colitis. METHODS Data were obtained from the American College of Surgeons National Surgical Quality Initiative Program from 2012-2018. Patients were included if they were >65 years old and had ulcerative colitis. Restorative and non-restorative surgeries were defined with procedure codes. Patient characteristics and adverse surgical outcomes were compared between restorative and non-restorative surgeries utilizing chi-square tests and Fisher's exact tests. Multivariate logistic regression models were constructed to evaluate the association of restorative versus non-restorative surgery with adverse surgical outcomes while adjusting for potential confounders. RESULTS Of 392 total patients, 95 had restorative and 297 had non-restorative surgery. Patients undergoing restorative surgery, compared to non-restorative surgery, were significantly younger (P<0.01), had lower incidences of steroid usage (P<0.001) and higher rates of readmission (P = 0.02). There were no differences in post-operative complications between the groups in both unadjusted analyses and covariate-adjusted regression analysis (P > 0.05). CONCLUSION In carefully selected older patients with ulcerative colitis, restorative surgery is associated with increased readmission, but otherwise similar rates of morbidity or mortality compared to non-restorative surgery. Data regarding postoperative functional outcome and quality of life are also needed to help select the most appropriate curative option for older adults.

Abstract
Objective This systematic review and meta-analysis aimed to compare published outcomes of patients undergoing laparoscopic versus open emergency colorectal surgery, with mortality as primary outcome. Background In contrast to the elective setting, the value of laparoscopic emergency colorectal surgery remains unclear. Methods PubMed, Embase, the Cochrane Library, and CINAHL were searched until January 6, 2021. Only comparative studies were included. Meta-analyses were performed using a random-effect model. The Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale were used for quality assessment. Results Overall, 28 observational studies and 1 randomized controlled trial were included, comprising 7865 laparoscopy patients and 55,862 open surgery patients. Quality assessment revealed 'good quality' in 16 of 28 observational studies, and low to intermediate risk of bias for the randomized trial. Laparoscopy was associated with significantly lower postoperative mortality compared to open surgery (odds ratio [OR] 0.44; 95% confidence interval [CI], 0.35-0.54). Laparoscopy resulted in significantly less postoperative overall morbidity (OR, 0.53; 95% CI, 0.43-0.65), wound infection (OR, 0.63; 95% CI, 0.45-0.88), wound dehiscence (OR, 0.37; 95% CI, 0.18-0.77), ileus (OR, 0.68; 95% CI 0.51-0.91), pulmonary (OR, 0.43; 95% CI, 0.24-0.78) and cardiac complications (OR, 0.56; 95% CI, 0.35-0.90), and shorter length of stay. No meta-analyses were performed for long-term outcomes due to scarcity of data. Conclusions The systematic review and meta-analysis suggest a benefit of laparoscopy for emergency colorectal surgery, with a lower risk of postoperative mortality and morbidity. However, the almost exclusive use of retrospective observational study designs with inherent biases should be taken into account.
