Association of Habitual Preoperative Dietary Fiber Intake With Complications After Colorectal Cancer Surgery.

IMPORTANCE: Postoperative complications are associated with increased morbidity and mortality among patients with colorectal cancer. As a modifiable factor associated with gut health, dietary fiber intake is of interest with regard to the risk of complications after surgery for colorectal cancer. OBJECTIVE: To examine the association between preoperative dietary fiber intake and risk of complications after surgery for colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used data from the Colorectal Longitudinal, Observational Study on Nutritional and Lifestyle Factors (COLON) study, which recruited adult patients with colorectal cancer at any stage at diagnosis from 11 hospitals in the Netherlands between August 2010 and December 2017. The present study included patients with stage I to IV colorectal cancer who underwent elective abdominal surgery. Data were analyzed between December 2019 and September 2020. EXPOSURES: Habitual dietary fiber intake was assessed at diagnosis using a 204-item food frequency questionnaire. MAIN OUTCOMES AND MEASURES: Any complications, surgical complications, and anastomotic leakage occurring during the 30 days after surgery for colorectal cancer. The association between fiber intake and risk of postoperative complications was assessed using logistic regression analyses. Additional analyses stratified by sex, tumor location, and fiber source were performed. RESULTS: Among the 1399 patients included in the analysis, the median age at inclusion was 66 years (interquartile range, 61-72 years) and 896 (64%) were men. Any complications occurred in 397 patients (28%), and surgical complications occurred in 235 patients (17%). Of 1237 patients with an anastomosis, 67 (5%) experienced anastomotic leakage. Higher dietary fiber intake (per 10 g per day) was associated with a lower risk of any complications (odds ratio [OR], 0.75; 95% CI, 0.62-0.92) and surgical complications (OR, 0.76; 95% CI, 0.60-0.97), whereas no association with anastomotic leakage was found (OR, 0.97; 95% CI, 0.66-1.43). Among women, higher dietary intake was associated with any complications (OR, 0.64; 95% CI, 0.44-0.94), whereas there was no association among men (OR, 0.79; 95% CI, 0.63-1.01). Fiber intake from vegetables (per 1 g per day) was inversely associated with any (OR, 0.90; 95% CI, 0.83-0.99) and surgical (OR, 0.87; 95% CI, 0.78-0.97) complications. CONCLUSIONS AND RELEVANCE: In this cohort study, higher habitual dietary fiber intake before surgery was associated with a lower risk of postoperative complications among patients with colorectal cancer. The findings suggest that improving preoperative dietary fiber intake may be considered in future prehabilitation programs for patients undergoing surgery for colorectal cancer.

Variation in palliative care of esophageal cancer in clinical practice: factors associated with treatment decisions.

Various treatments are available for the palliation of esophageal cancer, but the optimal therapeutic approach is unclear. This study aimed to assess the palliative treatment modalities used in patients with inoperable esophageal cancer and to identify factors associated with treatment decisions. A population-based, retrospective cohort study was conducted using data from the nationwide Netherlands Cancer Registry and medical records of seven participating hospitals. Patients diagnosed with stage III-IV inoperable esophageal or gastric cardia cancer in the central part of the Netherlands between 2001 and 2010 were included. Logistic regression analyses were performed to identify determinants of treatment choices. In total, 736 patients were initially treated with best supportive care (21%), stent placement (19%), chemotherapy (18%), external beam radiotherapy (EBRT) (16%), brachytherapy (6%), a combination of EBRT and brachytherapy (6%), a combination of chemotherapy and EBRT (5%) or another treatment (9%). The palliative approach varied for disease stage (P < 0.01) and hospital of diagnosis (P < 0.01). Independent factors affecting treatment decisions were age, degree of dysphagia, tumor histology, tumor localization, disease stage, and hospital of diagnosis. For example, patients diagnosed in one hospital were less likely to be treated with EBRT than with stent placement compared to patients in another hospital (odds ratio 0.20, 95% confidence interval 0.07-0.59). In conclusion, the initial palliative approach of patients with inoperable esophageal cancer varies widely and is not only associated with patient- and disease-related factors, but also with hospital of diagnosis. These findings suggest a lack of therapeutic guidance and highlight the need for more evidence on palliative care strategies for esophageal cancer.

The Development of a Liver Abscess after Screening Colonoscopy: A Calculated Risk?

We present the case of a patient who developed a liver abscess following screening colonoscopy. A colorectal screening program was introduced in the Netherlands in 2014 in order to reduce mortality from colorectal cancer. The patient in this report, a 63-year-old man with no significant medical history, underwent polypectomy of two polyps. Four days afterwards he presented to our emergency department with fever, nausea and vomiting. He was diagnosed with a Klebsiella pneumoniae liver abscess and was successfully treated with antibiotics for 6 weeks. This case highlights one of the risks of screening colonoscopy. Given the high number of colonoscopies due to the colorectal screening programs, we should be aware of complications in this mostly asymptomatic group of patients. LEARNING POINTS: Screening colonoscopy is a potential risk factor for Klebsiella pneumoniae liver abscess.It is thought that microperforations during colonoscopy could lead to bacterial invasion causing a pyogenic liver abscess.We expect the numbers of complications, including pyogenic liver abscess, to grow due to the increase in population-based screening programs for colorectal carcinoma.

Electromagnetic-Guided Bedside Placement of Nasoenteral Feeding Tubes by Nurses Is Non-Inferior to Endoscopic Placement by Gastroenterologists: A Multicenter Randomized Controlled Trial.

OBJECTIVES: Electromagnetic (EM)-guided bedside placement of nasoenteral feeding tubes by nurses may improve efficiency and reduce patient discomfort and costs compared with endoscopic placement by gastroenterologists. However, evidence supporting this task shift from gastroenterologists to nurses is limited. We aimed to compare the effectiveness of EM-guided and endoscopic nasoenteral feeding tube placement. METHODS: We performed a multicenter randomized controlled non-inferiority trial in 154 adult patients who required nasoenteral feeding and were admitted to gastrointestinal surgical wards in five Dutch hospitals. Patients were randomly assigned (1:1) to undergo EM-guided or endoscopic nasoenteral feeding tube placement. The primary end point was the need for reinsertion of the feeding tube (e.g., after failed initial placement or owing to tube-related complications) with a prespecified non-inferiority margin of 10%. RESULTS: Reinsertion was required in 29 (36%) of the 80 patients in the EM-guided group and 31 (42%) of the 74 patients in the endoscopy group (absolute risk difference -6%, upper limit of one-sided 95% confidence interval 7%; P for non-inferiority=0.022). No differences were noted in success and complication rates. In the EM-guided group, there was a reduced time to start of feeding (424 vs. 535 min, P=0.001). Although the level of discomfort was higher in the EM-guided group (Visual Analog Scale (VAS) 3.9 vs. 2.0, P=0.009), EM-guided placement received higher recommendation scores (VAS 8.2 vs. 5.5, P=0.008). CONCLUSIONS: EM-guided bedside placement of nasoenteral feeding tubes by nurses was non-inferior to endoscopic placement by gastroenterologists in surgical patients and may be considered the preferred technique for nasoenteral feeding tube placement.

Electromagnetic guided bedside or endoscopic placement of nasoenteral feeding tubes in surgical patients (CORE trial): study protocol for a randomized controlled trial.

BACKGROUND: Gastroparesis is common in surgical patients and frequently leads to the need for enteral tube feeding. Nasoenteral feeding tubes are usually placed endoscopically by gastroenterologists, but this procedure is relatively cumbersome for patients and labor-intensive for hospital staff. Electromagnetic (EM) guided bedside placement of nasoenteral feeding tubes by nurses may reduce patient discomfort, workload and costs, but randomized studies are lacking, especially in surgical patients. We hypothesize that EM guided bedside placement of nasoenteral feeding tubes is at least as effective as endoscopic placement in surgical patients, at lower costs. METHODS/DESIGN: The CORE trial is an investigator-initiated, parallel-group, pragmatic, multicenter randomized controlled non-inferiority trial. A total of 154 patients admitted to gastrointestinal surgical wards in five hospitals, requiring nasoenteral feeding, will be randomly allocated to undergo EM guided or endoscopic nasoenteral feeding tube placement. Primary outcome is reinsertion of the feeding tube, defined as the insertion of an endoscope or tube in the nose/mouth and esophagus for (re)placement of the feeding tube (e.g. after failed initial placement or dislodgement or blockage of the tube). Secondary outcomes include patient-reported outcomes, costs and tube (placement) related complications. DISCUSSION: The CORE trial is designed to generate evidence on the effectiveness of EM guided placement of nasoenteral feeding tubes in surgical patients and the impact on costs as compared to endoscopic placement. The trial potentially offers a strong argument for wider implementation of this technique as method of choice for placement of nasoenteral feeding tubes.

[Liver cirrhosis due to hepatitis E in a kidney transplant patient]. / Levercirrose door hepatitis E bij een niertransplantatiepatiënte.

Until recently, hepatitis E was considered to be an infectious disease that resolved without any long-term complications. We describe a 47-year-old woman who presented with a decompensated liver cirrhosis with ascites and peripheral oedema, 14 years after successful kidney transplantation. A previous extensive analysis of persistent liver enzyme disorders had not yielded a diagnosis, whereas now laboratory tests showed slightly abnormal liver results. The CT scan revealed ascites with signs of a decompensated liver cirrhosis. A liver biopsy revealed an active micronodular cirrhosis. Serological tests into the usual infectious causes of hepatitis provided no conclusive evidence but PCR on hepatitis E virus RNA and ELISA on virus-specific IgM and IgG were both positive on 2 occasions, suggestive for an active hepatitis E infection, the probable cause of the cirrhosis. The patient died several weeks later as a consequence of hepatic and renal failure. Hepatitis E was previously regarded as a travel-related disease from endemic areas. However, it is increasingly being observed in Western countries as well, where infection can take place due to intensive contact with animals and the consumption of infected meat.

Anal sphincter damage after vaginal delivery: relationship of anal endosonography and manometry to anorectal complaints.

PURPOSE: This study was designed to assess the relationship of anal endosonography and manometry to anorectal complaints in the evaluation of females a long time after vaginal delivery complicated by anal sphincter damage. METHODS: Thirty-four patients with anal sphincter damage after delivery, 22 with and 12 without anorectal complaints, and 12 controls without anorectal complaints underwent anal endosonography, manometry, and rectal sensitivity testing. Complaints were assessed by questionnaire, with a median follow-up of 19 years. RESULTS: Median maximum anal resting pressures were significantly lower in patients with anal sphincter damage with complaints (31 mmHg) than in controls (52 mmHg; P < 0.001). Median maximum anal squeeze pressures were significantly lower in patients with (55 mmHg) and without (69 mmHg) complaints than in controls (112 mmHg; P < 0.001 for both). Maximum anal resting pressures were significantly lower in patients with anorectal complaints after anal sphincter damage than in patients without complaints (P = 0.02). Results of anal manometry showed a large overlap between all groups. Rectal sensitivity showed no significant differences between the three groups. Persisting sphincter defects, shown by anal endosonography, were significantly more present in patients with anal sphincter damage after delivery with (86 percent) and without (67 percent) complaints than in controls (8 percent; P < 0.001 and P < 0.01, respectively). No differences in the number of echocardiographically proven sphincter defects were found between patients with or without anorectal complaints after anal sphincter damage CONCLUSIONS: Echographically proven sphincter defects are strongly associated with a history of anal sphincter damage during delivery. Sphincter defects are present in the majority of patients with anorectal complaints. Anal manometry provides little additional therapeutic information when performed after anal endosonography in patients with anorectal complaints after anal sphincter damage during delivery.

Recurrent bacterial cholangitis due to a juxtapapillary diverticulum.

We present a patient with recurrent bacterial cholangitis. Endoscopic retrograde cholangiopancreatography did not show evidence for choledocholithiasis or obstructing abnormalities of the common bile duct. However, a juxtapapillary diverticulum was situated at the edge of the papilla of Vater. We postulate that a juxtapapillary diverticulum can obstruct biliary flow due to its anatomical relation with the papilla, which may predispose to bacterial cholangitis. This might be prevented by sphincterotomy of the papilla.
