Zoals te zien is in gerelateerde artikelen hebben melkzuurbacteriën - probiotica heel vaak een gunstige invloed in vele opzichten en bij verschillende aandoeningen, ook gerelateerd aan kanker. Zo ook zijn er al verschillende studies gepubliceerd die bewijzen dat als patiënten met darmkanker vooraf en na een operatie bepaalde samenstellingen van melkzuurbacteriën / probiotica krijgen deze patiënten veel minder ernstige infecties krijgen en vaal sneller hun darmfunctie weer hersteld. En zijn de dagen dat ze in het ziekenhuis moeten blijven meestal korter in vergelijking met patiënten die geen melkzuurbacteriën / probiotica hebben gekregen / genomen. Wat niet eenduidig is is welke samenstellingen van melkzuurbacteriën - probiotica het beste effect hebben. Er zijn wereldwijd een aantal bedrijven die melkzuurbacteriën kweken en produceren en leveren aan bedrijven die leveren aan artsen en burgers. Het is dus altijd aan te raden om een deskundig arts of voedingsdeskundige te raadplegen wanneer u melkzuurbacteriën / probiotica wilt gaan gebruiken om welke reden dan ook. 

probiotica algemeen

Terug naar darmkanker en probiotica / melkzuurbacteriën.

Recent zijn twee reviewstudies gepubliceerd waarin een overzicht wordt gegeven van de effecten van melkzuurbacteriën / probiotica bij darmkanker operaties.

In deze meta-analyse van 9 gerandomiseerde studies: Probiotics Reduce Postoperative Infections in Patients Undergoing Colorectal Surgery: A Systematic Review and Meta-Analysis wordt een sterk effect gezien op het voorkomen van ernstige infecties en herstel na een operatie:

En in deze studie: Gut microbiome, surgical complications and probiotics. zien de onderzoekers dat naast de positieve effecten bij een operatie ook het reinigen van de darmen en herstellen van de darmflora na bv antibiotica of morfine betere resultaten met melkzuurbacteriën / probiotica worden bereikt in het herstellen van de darmflora:

Effects of mechanical bowel cleansing on the intestinal microbiota

Uit dit laatste studierapport:

een recente meta-analyse toonde een vermindering van postoperatieve sepsis na algemene chirurgie, zowel bij pro- en synbiotisch behandelde patiënten in vergelijking met placebo (respectievelijk P = 0,003 en 0,002). Er is echter geen significant verschil gevonden in de incidentie van pneumonie, urineweginfecties of chirurgische plaatselijke infecties , terwijl in een recent gepubliceerde studie een significante daling van 38% bij de incidentie van postoperatieve sepsis bleek.

Een afzonderlijke analyse gerelateerd aan het type operatie toonde een statistisch significant verschil tussen de verschillende typen van chirurgie, met een 35% risico vermindering in darmkanker chirurgie, 73% bij leverkanker en alvleesklierkanker operaties en een 56% risico vermindering bij levertransplantaties; Deze bevindingen tonen aan dat patiënten met chirurgie van darmkanker de moeilijkste groep zijn voor de manipulatie van de darmmicrobiële balans. [zie onderaan referentie 80].

In deze studie: Probiotics and synbiotics for the prevention of postoperative infections following abdominal surgery: a systematic review and meta-analysis of randomized controlled trials.

bleek een infectie op de plaats van de operatie bij 6.8% voor te komen bij patiënten die wel extra melkzuurbacteriën hadden gekregen tegenover 11.1% in de controlegroep. Dit blijkt een risicovermindering te geven van 37 procent. Deze studie onderstreepte ook het potentiële voordeel in relatie tot  urineweginfecties en samengestelde infecties, evenals het niet voorkomen van ernstige bijwerkingen die verband houden met de gebruikte melkzuurbacteriën, aldus de onderzoekers.

In onze literatuurlijst specifiek bij darmkanker worden een aantal studies vermeld onder het kopje probiotica / synbiotica / melkzuurbacteriën. Als u klikt op de studieomschrijving komt u bij de studierapporten. Inclusief die ik hierboven al heb genoemd.

Perioperative supplementation with bifidobacteria improves postoperative nutritional recovery, inflammatory response, and fecal microbiota in patients undergoing colorectal surgery: a prospective, randomized clinical trial

Abstract

The use of probiotics has been widely documented to benefit human health, but their clinical value in surgical patients remains unclear. The present study investigated the effect of perioperative oral administration of probiotic bifidobacteria to patients undergoing colorectal surgery. Sixty patients undergoing colorectal resection were randomized to two groups prior to resection. One group (n=31) received a probiotic supplement, Bifidobacterium longum BB536, preoperatively for 7–14 days and postoperatively for 14 days, while the other group (n=29) received no intervention as a control. The occurrences of postoperative infectious complications were recorded. Blood and fecal samples were collected before and after surgery. No significant difference was found in the incidence of postoperative infectious complications and duration of hospital stay between the two groups. In comparison to the control group, the probiotic group tended to have higher postoperative levels of erythrocytes, hemoglobin, lymphocytes, total protein, and albumin and lower levels of high sensitive C-reactive proteins. Postoperatively, the proportions of fecal bacteria changed significantly; Actinobacteria increased in the probiotic group, Bacteroidetes and Proteobacteria increased in the control group, and Firmicutes decreased in both groups. Significant correlations were found between the proportions of fecal bacteria and blood parameters; Actinobacteria correlated negatively with blood inflammatory parameters, while Bacteroidetes and Proteobacteria correlated positively with blood inflammatory parameters. In the subgroup of patients who received preoperative chemoradiotherapy treatment, the duration of hospital stay was significantly shortened upon probiotic intervention. These results suggest that perioperative oral administration of bifidobacteria may contribute to a balanced intestinal microbiota and attenuated postoperative inflammatory responses, which may subsequently promote a healthy recovery after colorectal resection.
