Abstract
BACKGROUND Malignant bowel obstruction (MBO) is a serious clinical entity that requires surgical intervention in almost 50% of cases. However, overall survival remains low even for operable cases. The aim of the present study was to investigate the correlation between patients' characteristics, perioperative details, histopathological results and postoperative outcomes of patients who were operated on due to MBO. METHODS A retrospective search of patients who were operated on due to MBO in a university and a rural hospital was conducted. Patients' characteristics, perioperative details, histopathological results and postoperative outcomes were reported. Univariable and multivariable analysis was performed. RESULTS Seventy patients were included with a mean age of 76.1 ± 10.6 years. The 30-day mortality rate was 18.6%, the Intensive Care Unit (ICU) admission rate was 17.1% and the mean length of stay (LOS) was 12.4 ± 5.7 days. Postoperative 30-day mortality was associated with increased age, known malignant recurrence, microscopically visible metastatic foci and defunctioning stoma creation. Colorectal malignancy type, sigmoid obstruction and primary anastomosis were correlated with decreased 30-day mortality. In addition, operation at the university hospital led to increased LOS, while stoma creation led to decreased LOS. Finally, ICU admission rates were increased for operations at university hospitals, at least one comorbidity, known malignant recurrence and longer preoperative waiting interval, whereas they were decreased for colorectal primary malignancy type. CONCLUSIONS Surgery due to MBO leads to increased morbidity and mortality. Therefore, prospective studies are needed to highlight inter-patient differences regarding the best individualized therapeutic strategy.

Abstract
PURPOSE The aim of this study was to compare baseline characteristics, 90-day mortality and overall survival (OS) between patients with obstructing and non-obstructing right-sided colon cancer at a national level. METHODS All patients who underwent resection for right-sided colon cancer between January 2015 and December 2016 were selected from the Netherlands Cancer Registry and stratified for obstruction. Primary outcome was 5-year OS after excluding 90-day mortality as assessed by the Kaplan-Meier and multivariable Cox regression analysis. RESULTS A total of 525 patients (7%) with obstructing and 6891 patients (93%) with non-obstructing right-sided colon cancer were included. Patients with right-sided obstructing colon cancer (OCC) were older and had more often transverse tumour location, and the pathological T and N stage was more advanced than in those without obstruction (p < 0.001). The 90-day mortality in patients with right-sided OCC was higher compared to that in patients with non-obstructing colon cancer: 10% versus 3%, respectively (p < 0.001). The 5-year OS of those surviving 90 days postoperatively was 42% in patients with OCC versus 73% in patients with non-obstructing colon cancer, respectively (p < 0.001). Worse 5-year OS was found in patients with right-sided OCC for all stages. Obstruction was an independent risk factor for decreased OS in right-sided colon cancer (HR 1.79, 95% CI 1.57-2.03). CONCLUSION In addition to increased risk of postoperative mortality, a stage-independent worse 5-year OS after excluding 90-day mortality was found in patients with right-sided OCC compared to patients without obstruction.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106906.

Abstract
BACKGROUND Right-sided obstructing colon cancer is most often treated with acute resection. Recent studies on right-sided obstructing colon cancer report higher mortality and morbidity rates than those in patients without obstruction. The aim of this study is to retrospectively analyse whether it is possible to optimise the health condition of patients with acute right-sided obstructing colon cancer, prior to surgery, and whether this improves postoperative outcomes. METHOD All consecutive patients with high suspicion of, or histologically proven, right-sided obstructing colon cancer, treated with curative intent between March 2013 and December 2019, were analysed retrospectively. Patients were divided into two groups: optimised group and non-optimised group. Pre-operative optimisation included additional nutrition, physiotherapy, and, if needed, bowel decompression. RESULTS In total, 54 patients were analysed in this study. Twenty-four patients received optimisation before elective surgery, and thirty patients received emergency surgery, without optimisation. Scheduled surgery was performed after a median of eight days (IQR 7-12). Postoperative complications were found in twelve (50%) patients in the optimised group, compared to twenty-three (77%) patients in the non-optimised group (p = 0.051). Major complications were diagnosed in three (13%) patients with optimisation, compared to ten (33%) patients without optimisation (p = 0.111). Postoperative in-hospital stay, 30-day mortality, as well as primary anastomosis were comparable in both groups. CONCLUSION This pilot study suggests that pre-operative optimisation of patients with obstructing right sided colonic cancer may be feasible and safe but is associated with longer in-patient stay.

Abstract
BACKGROUND Postoperative mortality and morbidity rates are high in patients with obstructing colon cancer (OCC). Different treatment options have been evaluated over the years, mainly for left sided OCC. Optimising the preoperative health condition in elective colorectal cancer (CRC) treatment shows promising results. The aim of this study is to determine whether preoptimisation is feasible in patients with OCC, with a special interest/focus on right-sided OCC, and if, ultimately, optimisation reduces mortality and morbidity (stoma rates, major and minor complications) rates in OCC. METHODS This is a prospective registration study including all patients presenting with OCC in our hospital. Patients with OCC, treated with curative intent, will be screened for eligibility to receive preoptimisation before surgery. The preoptimisation protocol includes; decompression of the small bowel with a NG-tube for right sided obstruction and SEMS or decompressing ileostomy or colostomy, proximal to the site of obstruction, for left sided colonic obstructions. For the additional work-up, additional nutrition by means of parenteral feeding (for patients who are dependent on a NG tube) or oral/enteral nutrition (in case the obstruction is relieved) is provided. Physiotherapy with attention to both cardio and muscle training prior surgical resection is provided. The primary endpoint is complication-free survival (CFS) at the 90 day period after hospitalisation. Secondary outcomes include pre- and postoperative complications, patient- and tumour characteristics, surgical procedures, total in hospital stay, creation of decompressing and/or permanent ileo- or colostomy and long-term (oncological) outcomes. DISCUSSION Preoptimisation is expected to improve the preoperative health condition of patients and thereby reduce postoperative complications. TRIAL REGISTRATION Trial Registry: NL8266 date of registration: 06-jan-2020. STUDY STATUS Open for inclusion.

Abstract
Objective A retrospective cohort study was carried out to research the effect of stent combined with laparoscopy combined with enhanced recovery after surgery (ERAS) in the operation of acute intestinal obstruction and to explore and analyze the prognostic factors. Methods During February 2019 to April 2021, sixty patients with acute intestinal obstruction cured in our hospital were enrolled. Randomly assigned control group patients (n = 50) were divided into the research group and control group patients. The control group accepted stent combined with laparoscopic therapeutic, and the research group accepted stent combined with laparoscopic therapeutic based on ERAS. The general data, operative index, Short Form 36 (SF-36) score, visual analogue scale (VAS) score, procalcitonin (PCT), CRP, prealbumin (PA) index, curative effect, and incidence of complications were investigated. Results No difference was found in age, gender, or type of disease among the general population (P > 0.05). A lower amount of blood was lost during the operation, less anal exhaustion was experienced by the research group, and a shorter hospital stay and lower hospitalization cost was experienced in the research group compared to the control group (P < 0.05). There exhibited no remarkable difference in SF-36 score and VAS score before operation, but after operation, the VAS score lessened, the SF-36 score augmented, while the VAS score was lower, and the SF-36 score in the research group was higher (P < 0.05). There exited no remarkable difference in the indexes of PCT, CRP, and PA before operation, but after operation, the levels of PCT and CRP lessened as well as the level of PA augmented, and the levels of PCT and CRP were lower, while the level of PA in the research group was higher. In terms of the clinical efficacy, the effective rate of the research group (98.00%) was higher compared to the control (86.00%) (P < 0.05). The main postoperative complications were pulmonary infection and incision infection. One case of incision infection occurred in the research group, and the probability of postoperative complications was 2.00%. In the control group, there were 3 cases of pulmonary infection, 0 cases of perforation, and 4 cases of incision infection, and the probability of postoperative complications was 14.00%. The prevalence in the research group was remarkably lower (P < 0.05). Conclusion Compared with the traditional concept of surgical therapeutic, it can more effectively reduce stress reaction, relieve postoperative pain, promote the recovery of postoperative gastrointestinal function as soon as possible, and reduce postoperative complications, which is worth to explore the application in the therapeutic of acute abdomen.

Abstract
Colorectal cancer remains a significant cause of morbidity and mortality, even despite curative treatment. A significant proportion of patients present emergently and have poorer outcomes compared to elective presentations, independent of TNM stage. In this systematic review and meta-analysis, differences between elective/emergency presentations of colorectal cancer were examined to determine which factors were associated with emergency presentation. A literature search was carried out from 1990 to 2018 comparing elective and emergency presentations of colon and/or rectal cancer. All reported clinicopathological variables were extracted from identified studies. Variables were analysed through either systematic review or, if appropriate, meta-analysis. This study identified multiple differences between elective and emergency presentations of colorectal cancer. On meta-analysis, emergency presentations were associated with more advanced tumour stage, both overall (OR 2.05) and T/N/M/ subclassification (OR 2.56/1.59/1.75), more: lymphovascular invasion (OR 1.76), vascular invasion (OR 1.92), perineural invasion (OR 1.89), and ASA (OR 1.83). Emergencies were more likely to be of ethnic minority (OR 1.58). There are multiple tumour/host factors that differ between elective and emergency presentations of colorectal cancer. Further work is required to determine which of these factors are independently associated with emergency presentation and subsequently which factors have the most significant effect on outcomes.

Abstract
AIM The aim was to assess long-term prognosis after emergency resection versus primary diverting stoma followed by elective tumour resection. METHOD A national-register-based cohort study with retrospective analysis of prospectively collected data was performed. All Swedish patients with non-metastatic obstructive locally advanced colon cancer treated with emergency resection or diverting stoma, followed by an elective resection, between 2007 and 2017 were included. The Kaplan-Meier method and Cox proportional hazards model were used to compare all-cause mortality between patients with emergency resection and elective right- and left-sided resection. The multivariable model was adjusted for year of diagnosis, age at diagnosis, sex, Charlson Comorbidity Index, American Society of Anesthesiologists class, tumour location and pN stage. RESULTS In all, 751 patients with a tumour in the right colon and 700 patients with a tumour in the left colon were included. Emergency resection was more common in patients with right-sided colon tumours (681/751) than in patients with left-sided colon tumours (483/700). The 5-year overall survival in patients with right-sided tumours was 25% after emergency resection and 46% after diverting stoma followed by elective resection (log-rank test P = 0.001). The corresponding numbers for patients with left-sided colon tumours were 40% and 64% (P < 0.001). Emergency resection was independently associated with increased all-cause mortality in patients with left-sided tumour (hazard ratio 1.63, 95% CI 1.21-2.19) but not in patients with right-sided tumour (hazard ratio 1.21, 95% CI 0.80-1.81). CONCLUSION Diverting stoma followed by elective resection is associated with improved survival compared with emergency resection in patients with left-sided colonic obstruction due to locally advanced tumours.

Abstract
Background The purpose of this study was to assess trends in incidence and presentation of colorectal cancer (CRC) over a period of 37 years in a stable population in Mid-Norway. Secondarily, we wanted to predict the future burden of CRC in the same catchment area. Methods All 2268 patients diagnosed with CRC at Levanger Hospital between 1980 and 2016 were included in this study. We used Poisson regression to calculate the incidence rate ratio (IRR) and analyse factors associated with incidence. Results The incidence of CRC increased from 43/100,000 person-years during 1980–1984 to 84/100,000 person-years during 2012–2016. Unadjusted IRR increased by 1.8% per year, corresponding to an overall increase in incidence of 94.5%. Changes in population (ageing and sex distribution) contributed to 28% of this increase, whereas 72% must be attributed to primary preventable factors associated with lifestyle. Compared with the last observational period, we predict a further 40% increase by 2030, and a 70% increase by 2040. Acute colorectal obstruction was associated with tumours in the left flexure and descending colon. Spontaneous colorectal perforation was associated with tumours in the descending colon, caecum, and sigmoid colon. The incidence of obstruction remained stable, while the incidence of perforation decreased throughout the observational period. The proportion of earlier stages at diagnosis increased significantly in recent decades. Conclusion CRC incidence increased substantially from 1980 to 2016, mainly due to primary preventable factors. The incidence will continue to increase during the next two decades, mainly due to further ageing of the population.

Abstract
BACKGROUND Treatment for obstructing colon cancer (OCC) is controversial because the outcome of acute resection is less favorable than for patients without obstruction. Few studies have investigated curable right-sided OCC, and patients with OCC usually undergo acute resection. This study aimed to better understand the outcome and best management of potentially curable right-sided OCC. METHODS A systematic review of studies was performed with a focus on differences in mortality and morbidity between emergency resection and staged treatment for patients with potentially curable right-sided OCC. In March 2019, the study searched Embase, Medline, Web of Science, Cochrane, and Google scholar databases according to PRISMA guidelines using search terms related to "colon tumour," "stenosis or obstruction and surgery," and "decompression or stents." All English-language studies reporting emergency or staged treatment for potentially curable right-sided OCC were included in the review. Emergency resection and staged resection were compared for mortality, morbidity, complications, and survival. RESULTS Nine studies were found to be eligible and comprised 600 patients treated with curative intent for their right-sided OCC by emergency resection or staged resection. The mean overall complication rate was 42% (range 19-54%) after emergency resection, and 30% (range 7-44%) after staged treatment. The average mortality rate was 7.2% (range 0-14.5%) after emergency resection and 1.2% (range 0-6.3%) after staged treatment. The 5-year disease-free and overall survival rates were comparable for the two treatments. CONCLUSIONS The patients who received staged treatment for right-sided OCC had lower mortality rates, fewer complications, and fewer anastomotic leaks and stoma creations than the patients who had emergency resection.

Abstract
BACKGROUND Little is known about metastatic patterns in patients with obstructing colorectal cancer (CRC). OBJECTIVE The aim of this study was to determine if metastatic patterns in patients with CRC differ between patients with or without obstruction. METHODS This single-center, observational, retrospective cohort study includes patients who underwent surgery for CRC between 2004 and 2015 in our hospital. Patients were divided into two groups-patients with or without obstructing CRC. All anatomic sites of distant metastases were reported. Differences in synchronous and metachronous metastases were compared between both groups. RESULTS A total of 2595 patients were included for analysis, of whom 315 (12%) presented with obstructing CRC. Synchronous metastases were diagnosed in 483 patients (19%). Patients with obstructing CRC and synchronous metastases, were diagnosed with peritoneal metastases more often than patients without obstruction (37% vs. 16%; p < 0.01). With regard to the location of the tumor, obstructing right-sided CRC patients were diagnosed with peritoneal metastases more often than patients without obstruction (52% vs. 21%; p < 0.01). Additionally, metachronous metastases were found significantly more often in patients with obstructing CRC (27%) compared with patients without obstruction (15%; p < 0.01). CONCLUSIONS Patients with obstructing CRC have more advanced tumor stage compared with patients without obstructing CRC. Synchronous peritoneal metastases are more often encountered in patients with obstructing CRC compared with patients without obstruction. This difference is due to the raised presence of synchronous peritoneal metastases in patients with obstructed right-sided colonic cancer. Furthermore, metachronous metastases are more often found in patients with obstructing CRC.
