Purpose: The purpose of this study was to evaluate the concordance between patient-reported performance status (prPS) and surgeon-reported performance status (srPS), and to assess the correlation between srPS and prPS and postoperative complications following elective colorectal cancer surgery. Not all patients are deemed suitable for undergoing a surgical procedure. We aimed to assess whether prPS can aid the surgeons' decision-making prior to surgery.

Methods: In this retrospective study, 524 patients undergoing colorectal cancer surgery were included. prPS were collected via questionnaires, while 30-day postoperative complications were obtained from the Danish Colorectal Cancer Group (DCCG) database. To evaluate the agreement between prPS and srPS, linearly weighted kappa statistics were applied. Rank-biserial correlation analysis was used to calculate the correlation between prPS and srPS with postoperative complications.

Results: In total, there was an approximate 71% concordance between the assessments. Around 17% of the patients rated themselves with a higher PS status than the surgeons, while 13% of the patients rated themselves with a lower PS. Overall postoperative complications, minor surgical complications, and medical complications were all significantly correlated to both srPS and prPS, while only srPS was correlated with major surgical complications. Neither srPS nor prPS were correlated with overall surgical complications (major and minor collapsed).

Conclusion: The agreement between prPS and srPS is poor and in nearly one-third of the cases, disagreement occurs. Overall, both prPS and srPS were correlated to postoperative complications, with srPS demonstrated a slightly higher correlation.

Purpose: To determine the clinical outcomes of endoscopic submucosal dissection (ESD) for colorectal tumors in older patients and predictors of mortality.

Methods: We retrospectively evaluated 207 lesions in 195 consecutive older patients aged ≥ 75 years who underwent ESD for colorectal tumors between January 2007 and December 2018. Outcomes of ESD were evaluated, and the prognosis was assessed in terms of both curability and the patient's baseline physical condition as determined by several indices. Cox regression analyses were performed to identify factors associated with reduced overall survival (OS).

Results: Treatment outcomes included a median procedure time of 55 min, en bloc resection rate of 97%, histological en bloc resection rate of 92%, postoperative bleeding rate of 2.4%, and intraoperative perforation rate of 3.4%. Postoperative bleeding and intraoperative perforation could be treated conservatively. Delayed perforation occurred in one patient and required emergency surgery. Three-year OS was 99.4% and 5-year OS was 95.8%. Overall, three patients experienced recurrence (one local, two distant metastasis), and one patient died of primary cancer. Multivariate analysis identified the Charlson Comorbidity Index (CCI) score ≥ 3 as the only independent predictor of reduced OS (hazard ratio 4.26; 95% confidence interval 1.60-11.38; P = 0.004).

Conclusion: Our results suggest that colorectal ESD is safe and effective in older patients aged ≥ 75 years. There was a significant independent association of reduced OS with high CCI score, but not with curability by ESD. The CCI score should be considered when determining the indications for ESD in older patients.

Background: The Skeletal Muscle Index (SMI) serves as an objective metric for assessing nutritional status in patients with malignant tumors. Research has found baseline nutritional status can influence both the efficacy and prognosis of targeted anti-tumor therapies, with growth factor tyrosine kinase inhibitors frequently inducing drug-related sarcopenia. Fruquintinib has received approval for the treatment of metastatic colorectal cancer. This study examines the prognostic significance of baseline SMI in patients with metastatic colorectal cancer undergoing treatment with fruquintinib. Additionally, the study investigates the incidence of SMI reduction following fruquintinib therapy to assess its impact on patient prognosis.

Methods: A retrospective multicenter study was conducted to analyze patients with metastatic colorectal cancer who received fruquintinib treatment across eight medical centers in Eastern China. The muscle area at the third lumbar vertebra was assessed, and both baseline and post-treatment SMI values were calculated independently. The relationship between SMI and patient survival was subsequently examined.

Results: The median progression-free survival (PFS) for the cohort of 105 patients was 4.2 months (95% CI, 3.7 to 4.9 months), while the median overall survival (OS) was 10.2 months (95% CI, 9.0 to 12.7 months). Notably, the baseline SMI prior to the initiation of fruquintinib therapy exhibited a significant correlation with OS (P = 0.0077). Multivariate analysis indicated that baseline SMI serves as an independent prognostic factor for OS (P = 0.005). Furthermore, after Propensity Score Matching (PSM) analysis, there was still a significant correlation between baseline SMI and OS. Among the patients, 28.87% developed sarcopenia following oral administration of fruquintinib. However, no statistically significant difference in OS was observed between the group with reduced SMI and the group without SMI reduction after treatment with fruquintinib.

Conclusion: The baseline SMI was identified as an independent prognostic factor for OS and may influence the survival outcomes of patients with metastatic colorectal cancer undergoing treatment with fruquintinib. Despite the potential of fruquintinib to induce sarcopenia, no significant correlation was observed between changes in SMI following treatment and patient survival.

Purpose: Colorectal cancer cells containing mobile lipids are said to be an early indicator of chemotherapy effects. The objective of the study was to examine the frequency and clinical relevance of intratumoral fat deposition in colorectal liver metastases (CRLM) post-chemotherapy using dual-echo chemical shift gradient-echo magnetic resonance imaging (MRI).

Methods: A retrospective analysis of 98 patients with CRLM diagnosed between 2017 and 2022 (69 M, mean age 62.87 ± 10.73 years old) who had an MRI after chemotherapy was performed. On dual-echo chemical shift gradient-echo MRI, intratumoral fat deposition of CRLM was evaluated. A signal intensity drop of ≥ 12% in opposed-phase images vs. in-phase images indicated intratumoral fat. After chemotherapy, the presence of fat deposition was correlated with patients' overall survival.

Results: Before and after chemotherapy, 0 (0%) and 29 (29.59%) patients exhibited intratumoral fat. The number of CRLM ranged from 1 to 25 with a median of 3 and a mean size of 32.58 ± 22.95 mm. The groups had statistically different survival times. Overall survival was shorter for patients with intratumoral fat deposition in CRLM (32 months (24-60, 95% CI)) than for patients without fat deposition in CRLM (48 months (36-NA, 95% CI)).

Conclusion: In our group, nearly 30% of CRLM patients exhibited intratumoral fat after chemotherapy. Patients with intratumoral fat deposition in CRLM have a shorter overall survival time. The presence of fat in CRLM correlates with a poor long-term prognosis.

Introduction: Recent studies have suggested that ambulatory management is feasible for acute uncomplicated diverticulitis (AUD); however, there is still no consensus regarding the most appropriate management settings. This study presents a multi-centre experience of managing patients presenting with AUD, specifically focusing on clinical outcomes and comparing ambulatory treatment with in-patient management.

Methods: A retrospective multi-centre study was conducted across four hospitals in the UK and included all adult patients with computed tomography (CT) confirmed (Hinchey grade 1a) acute diverticulitis over a 12-month period (January - December 2022). Patient medical records were followed up for 1-year post-index episode, and outcomes were compared between those treated through the ambulatory pathway versus inpatient treatment using 1:1 propensity score matching (PSM). All statistical analysis was performed using the R Foundation for Statistical Computing, version 4.4.

Results: A total of 348 patients with Hinchey 1a acute diverticulitis were included (260 in-patients; 88 ambulatory pathway), of which nearly a third (31.3%) had a recurrent disease. Inpatient management was dominant (74.7%), with a median of 3 days of hospital stay. PSM resulted in 172 patients equally divided between the two care settings. Ambulatory management was associated with a lower readmission rate (P = 0.02 before PSM, P = 0.08 after PSM), comparable surgical (P = 0.57 before PSM, 0% in both groups after PSM) and radiological interventions (P = 0.99 before and after PSM) within one year. In both matched and non-matched groups, a strong association between readmissions and inpatient management was noted in univariate analysis (P = 0.03 before PSM, P = 0.04 after PSM) and multivariate analysis (P = 0.02 before PSM, P = 0.03 after PSM).

Conclusion: Our study supports the safety and efficacy of managing patients with AUD through a well-designed ambulatory care pathway. In particular, hospital re-admission rates are lower and other outcomes are non-inferior to in-patient treatment. This has implications for substantial cost-savings and better utilisation of limited healthcare resources.

Background: The ileal pouch-anal anastomosis (IPAA) is a restorative procedure performed after proctocolectomy to improve quality of life in patients with colorectal conditions like ulcerative colitis, familial adenomatous polyposis, and selected cases of Crohn's disease and Lynch syndrome. However, severe pouch dysfunction can occur, often necessitating further surgical intervention.

Objective: This technical note aims to describe the operative approach and perioperative management for diverting ileostomy as a treatment for dysfunctional ileoanal pouches.

Methods: Indications for the procedure include complications such as pelvic sepsis, pouchitis, fistulas, and Crohn's disease of the pouch. Preoperative planning involves a multidisciplinary team, stoma site marking, and imaging to assess bowel integrity. The surgical technique utilizes laparoscopic access with careful adhesiolysis to minimize bowel injury, with intraoperative pouchoscopy to identify anatomical landmarks. An ileostomy is created by selecting a tension-free small bowel segment and approximating it to a pre-marked stoma site. Attention is given to preserving bowel length to allow for potential future restorative procedures. Postoperative care focuses on stoma management and addressing ongoing pouch dysfunction symptoms.

Conclusions: Diverting ileostomy offers symptom relief for patients with pouch dysfunction while avoiding more complex procedures like pouch excision. It is a valuable option in managing pouch failure.

Purpose: Endometriosis has a strong impact on women's quality of life (QoL). Pain is the main symptom of the disease, but bowel dysfunctions such as fecal incontinence, constipation and voiding difficulties are also reported. Patients could suffer from a Low Anterior Resection Syndrome (LARS)-like syndrome. Transanal irrigation (TAI), known to alleviate LARS-related symptoms, has been suggested to aid bowel dysfunction in endometriosis patients, potentially facilitating pelvic floor rehabilitation.

Methods: We retrospectively collected data from 60 patients with endometriosis and bowel dysfunction who had been prescribed with the Peristeen^® Plus TAI system. Patient satisfaction, pain, QoL and LARS score were evaluated before (baseline) and after TAI treatment (follow-up of approximately 12 months).

Results: Of the 60 patients meeting the inclusion criteria, 12 patients did not complete the questionnaires at follow-up and 16 patients discontinued treatment. Data analysis performed on 32 patients showed a mean increase of 3.6 points in patient satisfaction after TAI treatment and a mean pain reduction of 1.8 points (both, p-value < 0.001). LARS score decreased from a mean of 21.9 at baseline to a mean of 12.7 (p-value < 0.001). Accordingly, there was a notable improvement in patients' QoL.

Conclusion: TAI is a useful treatment for bowel dysfunctions in patients with endometriosis. When offered to these patients, TAI seems to represent a valuable strategy to reduce pelvic floor stress. This study confirms that TAI was associated to a significantly higher patients' satisfaction, as well as to a reduction of pain and LARS-like symptoms.

Background: To study the effect of laparoscopic ileopexy in patients with afferent-loop syndrome (ALS) after restorative proctocolectomy (RP).

Method: Ileopexy has been the treatment of choice in patients with ALS for the last 5 years at our department. All patients who had undergone ileopexy for ALS between January 2019 and August 2023 were identified. Data were extracted from the medical records. All patients were contacted and asked standardized questions regarding symptoms of ALS. A symptom score was calculated and compared before surgery and at the last follow-up.

Results: Ten patients, who had undergone ileopexy for ALS, were identified. Eight of these (80%) had been admitted with small bowel obstruction due to ALS. The remaining 2 patients had other symptoms indicative of ALS. In all patients, ileopexy was immediately effective in reducing symptoms. Symptoms recurred after 16.5 weeks (2-80) in 8 patients. Repeat laparoscopy showed that the ileopexy had slipped in 6 of these. Six had a new ileopexy with mesh. Later, one of these developed recurrent symptoms and had a new mesh ileopexy performed. No mesh complications were seen. Symptom score was reduced from 6.5 (1-9) to 2 (0-7) (p = 0.02) at the last follow-up.

Conclusions: In this study, ileopexy is effective in reducing symptoms of ALS after RP. In a high proportion of patients, it is necessary to use mesh to ensure long-term fixation of the ileum.

Purpose: The purpose of this study was to investigate the effects of postoperative complications on long-term survival after laparoscopic surgery for resectable colorectal cancer.

Methods: We retrospectively included 204 patients who underwent laparoscopic surgery for colorectal cancer from January 2016 to June 2020.

Results: Overall, 68 (33.3%) patients had postoperative complications, twelve (17.6%) of which were classified as Clavien-Dindo class 3a or higher. The 5-year overall survival rate of the non-complication and complication groups were 93.0% and 81.7%, respectively (p = 0.048; Kaplan-Meier analysis and log-rank test), and those among patients with stage III disease were 87.0% and 61.3%, respectively (p = 0.045). The 5-year disease-free survival rates were 85.6% and 77.4%, respectively (p = 0.042). Multivariable Cox proportional-hazards analysis revealed that nodal stage (hazard ratio, 8.392; 95% confidence interval, 1.892-37.175; p = 0.005) was an independent prognostic factor for overall survival, and postoperative complications (hazard ratio, 2.996; 95% confidence interval, 1.076-8.340; p = 0.036) were independent prognostic factors for disease-free survival.

Conclusion: Postoperative complications were associated with poor oncological outcomes, especially among patients with stage III colorectal cancer, and independent prognostic factors for disease-free survival.
