Effects of an artificial pancreas on postoperative inflammation in patients with esophageal cancer.

ABSTRACT:

Purposes

Subtotal esophagectomy for esophageal cancer (EC) is associated with high morbidity rates. Tight glycemic control using an artificial pancreas (AP) is one of the promising strategies to reduce postoperative inflammation and morbidities. However, the effects of tight glycemic control using AP in patients with EC are yet to be fully elucidated.

Method

This study reviewed 96 patients with EC who underwent subtotal esophagectomy. The postoperative inflammation parameters and morbidity rates were compared between patients who used the AP (n = 27) or not (control group, n = 69). AP is a closed-loop system that comprises a continuous glucose monitor and an insulin pump.

Results

The numbers of white blood cells (WBC) and Neutrophils (Neut) were noted to be lower in the AP group than in the control group, but with no significant difference. The ratio in which the number of WBC, Neut, and CRP on each postoperative day (POD) was divided by those tested preoperatively was used to standardize the results. The ratio of WBC and Neut on 1POD was significantly lower in the AP group than in the control group. The rate of surgical site infection was lower in the AP group than in the control group.

Conclusion

AP significantly decreased WBC and Neut on 1POD; this suggests the beneficial effects of AP in alleviating postoperative inflammation.

Project description:BackgroundGraft thrombosis is the main cause of early graft loss following pancreas transplantation, and is more frequent in pancreas transplant alone (PTA) compared with simultaneous pancreas-kidney (SPK) recipients. Ischemia-reperfusion injury during transplantation triggers a local thromboinflammatory response. We aimed to evaluate local graft inflammation and its potential association with early graft thrombosis.MethodsIn this observational study, we monitored 67 pancreas-transplanted patients using microdialysis catheters placed on the pancreatic surface during the first postoperative week. We analyzed 6 cytokines, interleukin-1 receptor antagonist (IL-1ra), IL-6, IL-8, interferon gamma-induced protein 10 (IP-10), macrophage inflammatory protein 1β (MIP-1β), IL-10, and the complement activation product complement activation product 5a (C5a) in microdialysis fluid. We compared the dynamic courses between patients with pancreas graft thrombosis and patients without early complications (event-free) and between PTA and SPK recipients. Levels of the local inflammatory markers, and plasma markers C-reactive protein, pancreas amylase, and lipase were evaluated on the day of thrombosis diagnosis compared with the first week in event-free patients.ResultsIL-10 and C5a were not detectable. Patients with no early complications (n = 34) demonstrated high IL-1ra, IL-6, IL-8, IP-10, and MIP-1β concentrations immediately after surgery, which decreased to steady low levels during the first 2 postoperative days (PODs). Patients with early graft thrombosis (n = 17) demonstrated elevated IL-6 (P = 0.003) concentrations from POD 1 and elevated IL-8 (P = 0.027) concentrations from POD 2 and throughout the first postoperative week compared with patients without complications. IL-6 (P < 0.001) and IL-8 (P = 0.003) were higher on the day of thrombosis diagnosis compared with patients without early complications. No differences between PTA (n = 35) and SPK (n = 32) recipients were detected.ConclusionsLocal pancreas graft inflammation was increased in patients experiencing graft thrombosis, with elevated postoperative IL-6 and IL-8 concentrations, but did not differ between PTA and SPK recipients. Investigating the relationship between the local cytokine response and the formation of graft thrombosis warrants further research.

Project description:Cancer is responsible for approximately 13% of all causes of death worldwide, and 20% of cancer patients die because of malnutrition and its complications. Malnutrition is common in cancer of stomach and esophagus. Although it is widely accepted that malnutrition adversely affects the postoperative outcome of patients, there is little evidence that perioperative nutrition support can reduce surgical risk in malnourished cancer patients. This prospective study was carried out from December 2016 to July 2017 at the Kidwai Memorial Institute of Oncology, Bengaluru. After stratified for age, sex, and tumor localization, patients were selected non-randomly and assigned to study (n = 30, 14 women, 16 men) and control group (n = 30, 14 women, 16 men) as alternate patients. Within 48 h of admission, patients underwent nutritional assessment by the subjective global assessment. Perioperative nutrition was administered in the study group by enteral route only. Patients had a functioning gastrointestinal tract, and they received enteral nutrition (EN). Target intake of non-protein (25 kcal/kg per day) and protein (0.25 g nitrogen/kg per day) was provided using available enteral formulas. This was supplementary to standard hospital diet. Nutritional re-assessment after 15 days of intervention showed significant change in nutritional status, which was measured as gain in weight for each patient. There were significant differences in the mortality and complications between the two groups. The total length of hospitalization and postoperative stay of the control patients were significantly longer than those of the study patients. In conclusion, perioperative nutrition support can decrease the incidence of postoperative complications in moderately and severely malnourished gastric and esophageal cancer patients. In addition, it is effective in reducing mortality. Enteral nutrition support alone can be used in the management of malnourished patients undergoing gastric and esophageal surgery.
