Emergency resection or diverting stoma followed by elective resection in patients with colonic obstruction due to locally advanced cancer: a national cohort study

From Diversion to Permanence: Trends in Ostomy Creation in Rectal Cancer Surgery

Rectal cancer surgery has undergone transformative advancements over the past few decades, evolving from radical, high-morbidity procedures to more refined techniques focused on both oncological outcomes and the preservation of anorectal function. This review provides a brief overview of the history of rectal cancer surgery, highlighting key innovations in imaging, neoadjuvant therapy, and minimally invasive techniques that have significantly reduced the need for permanent and temporary ostomies. Additionally, the current indications for both permanent and temporary ostomies are reviewed, including a discussion of associated complications, such as non-reversal, parastomal hernias, stomal prolapse, stenosis, and skin-related issues, along with strategies and techniques to mitigate these complications. This review underscores the importance of ongoing innovation and individualized surgical planning to enhance patient outcomes in rectal cancer care by understanding the historical context, contemporary practices, and associated challenges.

Long-term outcomes after postponing surgery to optimise patients with acute right-sided obstructing colon cancer

AIM

To retrospectively analyse the short- and long-term oncological, morbidity and mortality outcomes in patients diagnosed with acute right-sided obstructing colon cancer. Patients who underwent pre-optimisation prior to the oncological resection were compared to patients who did not undergo pre-optimisation.

METHODS

All consecutive patients with right-sided obstructing colon cancer, either with a high clinical suspicion or confirmed diagnosis by histological analysis, who underwent curative-intent treatment between March 2013 and December 2020 were included. Patients were divided into two groups: an optimised group and a non-optimised group. Preoperative optimisation included additional nutrition, physiotherapy, and, if needed, bowel decompression. Data about disease-free survival and mortality were collected up to three years after surgery.

RESULTS

Sixty-two patients were included. Thirty patients underwent the optimisation protocol before postponed surgery, and 32 patients received emergency surgery, without optimisation (surgery performed with a median of 9.6 days versus 22 h after admission). The postoperative complication rate was significantly lower in the optimisation group (50 % vs 78 %, p = 0.033). No significant differences were found in the 90-day mortality rate (7 % vs 13 %, p = 0.672) and three-year overall survival rate (43 % vs 56 %, p = 0.49). After three years, sixteen (53 %) patients in the optimised group and twenty (63 %) in the non-optimised were deceased (p = 0.672).

CONCLUSION

Postponing the surgery with preoperative optimisation in patients with obstructing right-sided colon cancer results in a significantly lower 90-day complication rate and suggests no negative effect on survival rates compared to an acute resection. Although, further research with a larger sample size is needed.

Short-term morbidity and mortality after right hemicolectomy: an update of national performance in the Netherlands

AIM

The purpose of this Dutch retrospective population-based study was to evaluate how short-term outcomes and inter-hospital variability after right hemicolectomy for colon cancer have evolved between 2012 and 2020.

METHOD

Patients who underwent right hemicolectomy for primary solitary colon cancer between 1 January 2012 and 31 December 2020 and were registered in the Dutch Colorectal Audit were included. Surgical characteristics and outcomes were assessed during three time periods (2012-2014, 2015-2017, 2018-2020). Complications and mortality were the primary outcomes, and reintervention, readmission and length of stay secondary outcomes.

RESULTS

In total, 29 274 patients were included. Significant increase in minimally invasive surgery (51.1% 2012-2014, 73.2% 2015-2017, 85.0% 2018-2020), increase in conversion (6.6%, 7.8%, 9.1%, P < 0.001) and decrease in acute/urgent resections (15.9%, 11.7%, 10.9%, P < 0.001) were found. The overall complication rate was slightly lower in the third period (30.9%, 30.6%, 28.8%, P = 0.004), primarily because of decreasing non-surgical complications (19.7%, 20.6%, 17.6%, P < 0.001), while surgical complications remained unchanged (17.5%, 18.3%, 18.2%, P = 0.277). Postoperative mortality was 3.4%, 2.3% and 3.5%, respectively. Reintervention rate slightly decreased (9.4%, 8.3%, 8.6%, P < 0.001). The proportion of patients admitted for more than 6 days decreased over time (54.3%, 42.4%, 34.3%, P < 0.001), with an increase in readmission rate (7.4%, 6.8%, 9.3%, P < 0.001). Inter-hospital variability decreased over time for complications, length of stay and conversion.

CONCLUSION

This study shows a national decreasing inter-hospital variability in clinical outcomes after right hemicolectomy and a decrease in postoperative complications. Despite increasing use of laparoscopy, surgical complications and mortality remained stable over time.

Exploring 6 years of colorectal cancer surgery in rural Italy: insights from 648 consecutive patients unveiling successes and challenges

The multidisciplinary management of patients suffering from colorectal cancer (CRC) has significantly increased survival over the decades and surgery remains the only potentially curative option for it. However, despite the implementation of minimally invasive surgery and ERAS pathway, the overall morbidity and mortality remain quite high, especially in rural populations because of urban - rural disparities. The aim of the study is to analyze the characteristics and the surgical outcomes of a series of unselected CRC patients residing in two similar rural areas in Italy. A total of 648 consecutive patients of a median age of 73 years (IQR 64-81) was enrolled between 2017 and 2022 in a prospective database. Emergency admission (EA) was recorded in 221 patients (34.1%), and emergency surgery (ES) was required in 11.4% of the patients. Tumor resection and laparoscopic resection rates were 95.0% and 63.2%, respectively. The median length of stay was 8 days. The overall morbidity and mortality rates were 23.5% and 3.2%, respectively. EA was associated with increased median age (77.5 vs. 71 ys, p < 0.001), increased mean ASA Score (2.84 vs. 2.59; p = 0.002) and increased IV stage disease rate (25.3% vs. 11.5%, p < 0.001). EA was also associated with lower tumor resection rate (87.3% vs. 99.1%, p < 0.001), restorative resection rate (71.5 vs. 89.7%, p < 0.001), and laparoscopic resection rate (36.2 vs. 72.6%, p < 0.001). Increased mortality rates were associated with EA (7.2% vs. 1.2%, p < 0.001), ES (11.1% vs. 2.0%, p < 0.001) and age more than 80 years (5.8% vs. 1.9%, p < 0.001). In rural areas, high quality oncologic care can be delivered in CRC patients. However, the surgical outcomes are adversely affected by a still too high proportion of emergency presentation of elderly and frail patients that need additional intensive care supports beyond the surgical skill and alternative strategies for earlier detection of the disease.

The ELECLA trial: A multicentre randomised control trial on outcomes of neoadjuvant treatment on locally advanced colon cancer

BACKGROUND

Colon cancer (CC) is a public health concern with increasing incidence in younger populations. Treatment for locally advanced CC (LACC) involves oncological surgery and adjuvant chemotherapy (AC) to reduce recurrence and improve overall survival (OS). Neoadjuvant chemotherapy (NAC) is a novel approach for the treatment of LACC, and research is underway to explore its potential benefit in terms of survival. This trial will assess the efficacy of NAC in LACC.

METHODS

This is a multicentre randomised, parallel-group, open label controlled clinical trial. Participants will be selected based on homogenous inclusion criteria and randomly assigned to two treatment groups: NAC, surgery, and AC or surgery followed by AC. The primary aim of this study is to evaluate the 2-year progression-free survival (PFS), with secondary outcomes including 5-year PFS, 2- and 5-year OS, toxicity, radiological and pathological response, morbidity, and mortality.

DISCUSSION

The results of this study will determine whether NAC induces a clinical and histological tumour response in patients with CCLA and if this treatment sequence improves survival without increasing morbidity and mortality.

Timing of restoration of bowel continuity after decompressing stoma, in left-sided obstructive colon cancer: a nationwide retrospective cohort

BACKGROUND

With the increasing use of decompressing stoma as a bridge to surgery for left-sided obstructive colon cancer (LSOCC), the timing of restoration of bowel continuity (ROBC) is a subject of debate. There is a lack of data on immediate ROBC during elective resection as an alternative for a 3-stage procedure. This study analysed if immediate ROBC during tumour resection is safe and of any benefit for patients who underwent decompressing stoma for LSOCC.

METHODS

In a Dutch nationwide collaborative research project, 3153 patients who underwent resection for LSOCC in 75 hospitals (2009-2016) were identified. Extensive data on disease and procedural characteristics, and outcomes was collected by local collaborators. For this analysis, 332 patients who underwent decompressing stoma followed by curative resection were selected. Immediate ROBC during tumour resection was compared to two no immediate ROBC groups, (1) tumour resection with primary anastomosis (PA) with leaving the decompressing stoma in situ, and (2) tumour resection without PA.

RESULTS

Immediate ROBC was performed in 113 patients (34.0%) and no immediate ROBC in 219 patients [168 with PA (50.6%) and 51 patients without PA (15.4%)]. No differences at baseline between the groups were found for age, ASA score, cT, and cM. Major surgical complications (8.8% immediate ROBC vs. 4.8% PA with decompressing stoma and 7.8% no PA; P =0.37) and mortality (2.7% vs. 2.4% and 0%, respectively; P =0.52) were similar. Immediate ROBC resulted in a shorter time with a stoma (mean 41 vs. 240 and 314 days, respectively; P <0.001), and fewer permanent stomas (7% vs. 21% and 80%, respectively; P <0.001) as compared to PA with a decompressing stoma or no PA.

CONCLUSION

After a decompressing stoma for LSOCC, immediate ROBC during elective resection appears safe, reduces the total time with a stoma and the risk of a permanent stoma.

Surgical treatment and overall survival in patients with right-sided obstructing colon cancer-a nationwide retrospective cohort study

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.

Impact of two waves of Sars-Cov2 outbreak on the number, clinical presentation, care trajectories and survival of patients newly referred for a colorectal cancer: A French multicentric cohort study from a large group of university hospitals

The SARS‐Cov2 may have impaired care trajectories, patient overall survival (OS), tumor stage at initial presentation for new colorectal cancer (CRC) cases. This study aimed at assessing those indicators before and after the beginning of the pandemic in France. In this retrospective cohort study, we collected prospectively the clinical data of the 11.4 million of patients referred to the Greater Paris University Hospitals (AP‐HP). We identified new CRC cases between 1 January 2018 and 31 December 2020, and compared indicators for 2018‐2019 to 2020. pTNM tumor stage was extracted from postoperative pathology reports for localized colon cancer, and metastatic status was extracted from CT‐scan baseline text reports. Between 2018 and 2020, 3602 and 1083 new colon and rectal cancers were referred to the AP‐HP, respectively. The 1‐year OS rates reached 94%, 93% and 76% for new CRC patients undergoing a resection of the primary tumor, in 2018‐2019, in 2020 without any Sars‐Cov2 infection and in 2020 with a Sars‐Cov2 infection, respectively (HR 3.78, 95% CI 2.1‐7.1). For patients undergoing other kind of anticancer treatment, the percentages are 64%, 66% and 27% (HR 2.1, 95% CI 1.4‐3.3). Tumor stage at initial presentation, emergency level of primary tumor resection, delays between the first multidisciplinary meeting and the first anticancer treatment did not differ over time. The SARS‐Cov2 pandemic has been associated with less newly diagnosed CRC patients and worse 1‐year OS rates attributable to the infection itself rather than to its impact on hospital care delivery or tumor stage at initial presentation.
