This is a rare case of infantile intestinal obstruction managed during COVID-19 pandemic. Acute intestinal obstruction due to a congenital anomalous band is rare in infants and children, and if not treated promptly, can lead to morbidity and mortality. Various reasons, such as congenital, acquired, and extrinsic or intrinsic pathologies in children and adults, may be the cause for acute intestinal obstruction. Congenital anomalous bands account for 3% of the intestinal obstructions in infants and children. These bands may cause ischemia and gangrene of the bowel without timely intervention.","PeriodicalId":90396,"journal":{"name":"World journal of colorectal surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139365385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Real-time artificial intelligence-assisted colonoscopy and the effect of endoscopist experience on polyp detection rates at a tertiary referral center","authors":"I. Seow-En, S. Khor, Yun Zhao, Yvonne Ng, Emile Wei Tan","doi":"10.4103/wjcs.wjcs_27_23","DOIUrl":"https://doi.org/10.4103/wjcs.wjcs_27_23","url":null,"abstract":"Background: In recent years, new technology has emerged with the potential to considerably influence the future landscape of gastrointestinal endoscopy. One example of this is real-time artificial intelligence-assisted colonoscopy (AIC). Reported improvements in polyp detection rate (PDR) and adenoma detection rate (ADR) over standard colonoscopy (SC) have led to its rapid adoption in several tertiary endoscopy centers worldwide. However, many clinicians have mixed attitudes concerning the use of AIC. Similar to other skill-based procedures, the quality of endoscopy is directly proportional to the technical expertise and proficiency of the endoscopist. Objective: To evaluate the use of real-time AIC versus SC at a tertiary, high-volume referral center. Design: Retrospective cohort study. Settings: Single tertiary referral center. Patient and Methods: Data was retrospectively analyzed from patients who underwent elective colonoscopy at Singapore General Hospital from August 1, 2022 to October 31, 2022. Main Outcome Measures: The primary study outcome was PDR and ADR. Subgroup analysis assessed the differences in polyp detection according to the experience level of the endoscopist. Sample Size: Eight hundred and fifty-nine patients. Results: Over the 3-month study period, 859 patients underwent complete colonoscopies performed by nine accredited endoscopists; 430 patients underwent SC and 429 underwent AIC. Both groups were statistically similar in age, gender, and indication for colonoscopy. The median ADR was 34.2% (range, 24.6%–57.3%) for the entire cohort. Overall detection rates were higher for AIC than SC for diminutive polyps (≤5 mm) (45.7% vs 38.6%, P = 0.045), sessile polyps (48.5% vs 37.4%, P = 0.009), and polyps with adenomatous (42.4% vs. 36.3%, P = 0.043) or serrated histology (1.2% vs. 0%, P = 0.025). Using SC, PDR among junior versus senior endoscopists was comparable at 47.9% vs 45.6% (P = 0.672) and ADR at 36.1% vs 36.8% (P = 0.912). With real-time AI enhancement, PDR and ADR for junior endoscopists considerably increased over their senior counterparts, with PDR at 69.5% vs 44.9% (P = 0.0001) and ADR at 50.0% vs 37.7% (P = 0.016). Among senior endoscopists, AIC did not result in any statistical improvement of PDR (P = 0.999) and ADR (P = 0.854) compared to SC. Conclusions: AIC significantly increases PDR and ADR compared to SC, particularly for detecting diminutive and sessile polyps. This benefit was only observed among less experienced endoscopists. Limitations: This study is limited by its retrospective nature, short study duration, and availability of the AI system, leading to practical constraints. Conflict of Interest: The authors have no conflict of interest to declare.","PeriodicalId":90396,"journal":{"name":"World journal of colorectal surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139365080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seow-En","doi":"10.4103/wjcs.wjcs_29_23","DOIUrl":"https://doi.org/10.4103/wjcs.wjcs_29_23","url":null,"abstract":"Background: Despite the improvements in the incidence rate and mortality of colorectal cancer in Singapore, most cases are still diagnosed at later stages. This suggests limitations in the uptake of cancer screening, relating to suboptimal population awareness, unfamiliarity with tests, or cost concerns. Objective: We report our experience with a charity colonoscopy event to assist patients with endoscopy costs, raise public awareness of endoscopic cancer screening, and demonstrate the safety of colonoscopy. Design and Settings: The Singapore General Hospital (SGH) Preventing Rectal and Colon Cancer through Endoscopy (SPRUCE) fund was established in 2019. A charity endoscopic event was held to kickstart the official launch of the fund with corporate, individual, and industry support. Patients and Methods: The recruitment criteria were first-visit patients who required colonoscopic evaluation following specialist evaluation and those in possession of a Community Health Assist Scheme card, for which only Singapore citizens whose annual household per capita income was less than Singapore dollar (SGD) 24,000 (USD 17,500) were eligible. This enabled meaningful selection of patients who would most benefit from financial assistance. Main Outcome Measures: To determine the feasibility of a charity colonoscopy event while raising colorectal cancer public awareness. Sample Size: Forty-eight patients underwent colonoscopies by accredited endoscopists for the SPRUCE endoscopy event. Results: Of the 48 participants, 19 (39.5%) were men and 29 (60.4%) were women, with a median age of 64 years. Seven patients (14.6%) had a normal colonoscopy, while 42 (85.4%) had at least one abnormality documented. Forty-one benign polyps were detected and removed in 22 patients (45.8%), with an overall adenoma detection rate of 85.4%. One patient (2.1%) was diagnosed with colon cancer. No complications resulted from the procedures performed during the charity event. Conclusion: A charity colonoscopy event conducted in the form of a health fair for needy patients is feasible and may help raise colorectal cancer awareness. This framework may serve as a useful basis for similar future events held in Singapore or elsewhere. Limitations: Lack of longitudinal assessment of colorectal cancer awareness among the public, following the charity colonoscopy event.

Although the number of stoma patients is increasing, the relationship between peristomal disorders and QOL is not widely understood. Objectives: The aim of this study was to elucidate the relationship between the QOL status of stoma patients and the condition of the peristomal skin through structural equation modeling (SEM), which could help provide a comprehensive overview of the factors affecting the health of such patients. Design: Observational study of prospectively collected data. Setting: This study was conducted in the colorectal unit of two educational hospitals in Sapporo, Japan. Patients and Methods: Outpatient patients with a stoma were recruited between July 11, 2019 and November 30, 2019. The relationship among the clinical variables were identified using SEM analysis. Sample Size: Sixty-seven consecutive stoma patients. Main Outcome Measures: The Ostomy Skin Tool [used to assess the discoloration, erosion, and tissue overgrowth (DET) score], Stoma-QOL, Hospital Anxiety and Depression Scale (HADS), and the EQ-5D-5L questionnaire were employed. Results: The observation period in the low DET score group was longer than that in the high DET score group. An SEM-derived path diagram, which exhibited high goodness-of-fit indices, revealed the relationships among the clinical factors. Patient satisfaction was positively associated with the Stoma-QOL score and negatively associated with the HADS-anxiety score but not the HADS-depression score. Conclusions: Peristomal skin disorders did not affect QOL or mental health status. The QOL scores of the patients with mild peristomal skin disorders markedly varied. Anxiety, but not depression, reduced the satisfaction of stoma patients and was alleviated over time.

Oncological surgical resection is the most effective method to achieve a successful outcome, but the prognosis of recurrence is poor. Objectives: The objective of our study was to provide an insight into our management of patients who have experienced recurrences by first assessing the 5-year survival rate of patients who underwent curative surgery for right-sided colon cancer and then reporting on the rate and management of recurrences. Study Design: We conducted a retrospective study using a prospective database of patients with recurrent colon cancer following an initial curative right-sided resection. Setting: In the study, patients diagnosed and treated at King's College Hospital for colorectal cancer between 2011 and 2015 were included. Patients and Methods: The study included patients with right-sided colonic adenocarcinoma (including the cecum, ascending colon, hepatic flexure, and proximal two-thirds of the transverse colon) who had undergone curative surgical resection and had completed follow-up. Main Outcome Measures: Our main outcome measures were survival after curative resection of right-sided colon cancers, recurrence, and survival after recurrence. Sample Size: Our study included 195 patients. Results: In this study, 195 patients with stages I–III right-sided colonic tumors were treated with primary curative surgical resection (R0), of which 173 (86.7%) were treated electively and 22 (11.3%) were treated as an emergency. A total of 104 men (53.3%) and 91 women (46.7%) participated in our study, and the mean age at diagnosis was 69.2 (12.8) years. After a 5-year follow-up period, 145 patients (74.4%) successfully completed the follow-up with no loss of patients. We noted that 88.7% of the patients had no recurrence, but 22 (11.3%) of 195 patients experienced recurrences and 28 (14.4%) died. Following further analysis of the patients with recurrences, we found that 13 (6.6%) had distant metastases, seven (3.5%) had local recurrences, and two (1.2%) had multiple recurrences. The mean time to recurrence was 15.1 (10.8) months. Recurrence was associated with a mean survival rate of 39.64 (19.2) months compared to 53.9 ± 15.1 for patients without recurrence (Log Rank P = 0.000). Among patients with recurrences, the 5-year survival rate was 31.8%; however, it was 80.9% (Log Rank P = 0.000) for those without recurrences. Patients with recurrent cancer who received curative treatment had a 5-year survival rate of 40.0% compared to 14.3% for those who received palliative treatments (Log Rank P = 0.068). Conclusion: In our study, right-sided colorectal cancer after oncological surgical resection was associated with a recurrence rate of 11.3%. The survival rate was inversely proportional to the stage of the disease at the time of diagnosis. Detection of recurrence and surgical intervention in a timely manner are associated with improved survival rates.

Antibiotic therapy in patients with acute uncomplicated diverticulitis (AUD) has been questioned. Currently, there is limited data on the quality of life (QoL) of patients after AUD. Objectives: The aim of this study was to investigate the long-term QoL in patients with AUD and to assess if antibiotic therapy or recurrent disease impacts the QoL of patients. Design: Cross-sectional questionnaire study. Setting: Two teaching hospitals in Southern Sweden. Patient and Methods: The records of patients who were treated for AUD from 2015 to 2017 were extracted, and their medical charts were used to gather data. Three questionnaires (EuroQol-5 Dimension-5L, the Gastrointestinal Quality of Life Index, and the short health scale) were sent 3–5 years after hospitalization (year 2020) to evaluate the QoL of the patients. Main Outcome Measure: Long-term QoL measured by the aforementioned questionnaires. Sample Size: The original cohort was reduced to 509 due to death, duplications, and sigmoid colectomy. The final patient cohort consisted of 273 patients after exclusion of non-responders or patients who declined participation. Results: In the EuroQol-5 Dimension scale, 147 (55%) patients reported problems in one or more QoL dimension but only 4% experienced severe problems. The Gastrointestinal Quality of Life Index median score was 105.0 (90.0–113.8), while the median short health scale score was 4.0 (0.9–12.5). Among the patients, 76% were treated with antibiotics, but no differences were observed between the antibiotics and no antibiotics groups in any QoL score. Recurrent disease was associated with lower QoL scores. Conclusion: This study showed that 161 (59%) of the patients with AUD experienced QoL problems, with recurrent disease being a risk factor. Antibiotic therapy did not affect the long-term QoL of the patients. Larger prospective studies are needed to confirm these results, and future efforts should be made to prevent the recurrence of AUD. Limitations: Limited sample size, non-randomized study.
