Understanding Clinical Issues in Postoperative Nutrition After Pancreaticoduodenectomy

Pneumatosis in Post-Whipple Patients

Pneumatosis intestinalis (PI) is the finding of air in the wall of the intestine. Clinical significance ranges from an incidental radiologic finding to an indicator of life-threatening disease requiring surgical intervention. We report the incidence and consequence of PI in a 7-year, single-surgeon, retrospective review. Data from demographics, imaging, and outcomes were analyzed. Two-tailed Fisher's exact test was performed to analyze the difference between groups. A total of 214 patients underwent a Whipple procedure with a routinely placed feeding tube during this period. Most had a gastrojejunal feeding tube, 80.4 per cent. Thirteen patients developed PI. Overall reoperation rate was nine of 201 versus four of 13 in the PI group ( P < 0.02). Three patients taken back to the operating room with peritonitis and PI had a necrotic bowel. A fourth patient was taken to surgery for unrelenting upper gastrointestinal bleeding. The remaining nine were managed nonoperatively with resolution of PI. The 90-day death rate in those without PI was 2.9 per cent versus 23.3 per cent with PI ( P < 0.02). Isolated PI can be managed nonoperatively; however, in the presence of peritonitis, it is a strong predictor of lethal complications.

Impact of fast-track concept elements in the classical pancreatic head resection (Kausch-Whipple procedure)

The aim of the study was to determine statistically significant factors with an impact on the early postoperative surgical outcome.

MATERIAL AND METHODS

The influence of applied fast-track components on surgical results and early postoperative outcome in 143 consecutive Kausch-Whipple procedure patients was evaluated in a single-center retrospective analysis of a prospective collection of patient-associated pre-, peri- and postoperative data from 1997-2006.

RESULTS

The in-hospital mortality rate was 2.8% (n=4). Fast-track measures were shown to have no effect on the morbidity rate in the multi-variate analysis. Over the study period, a decrease of intraoperative infusion volume from 14.2 mL/kg body weight/h in the first year to 10.7 mL/kg body weight/h in the last year was accompanied by an increase in patients requiring intraoperative catecholamines, up from 17% to 95%. The administration of ropivacain/sufentanil via thoracic peri-dural catheter injection initiated in 2000 and now considered the leading analgesic method, was used in 95% of the cases in 2006. Early extubation rate rose from 16.6% to 57.9%.

CONCLUSIONS

Fast-track aspects in the perioperative management have become more important in several surgical procedure even in those with a greater invasiveness such as Kausch-Whipple. However, such techniques used in peri-operative management of Kausch-Whipple pancreatic-head resections had no impact on the morbidity rate. In addition, the low in-hospital mortality rate was particularly attributed to surgical competence.

Hospital Volume and Inpatient Mortality After Cancer-Related Gastrointestinal Resections: The Experience of an Asian Country

BACKGROUND

Using 4-year nationwide population-based data for Taiwan, this study compared in-hospital surgical mortality rates with hospital volume for five cancer-related gastrointestinal resections.

METHODS

The study sample was drawn from the Taiwan National Health Insurance Research Database. A total of 34,715 patients, each of whom had undergone a cancer-related colectomy, gastrectomy, esophagectomy, pancreatic resection, or liver lobectomy between 2000 and 2003, were selected as the study sample. The outcome measure was in-hospital mortality. The study sample was categorized into five patient groups for each procedure, and logistic regression analyses were performed for each procedure after adjustment for hospital and patient characteristics to assess the independent association between hospital volume and in-hospital mortality.

RESULTS

The adjusted odds ratios showed a steady decline in mortality rates for colectomy, gastrectomy, esophagectomy, and liver lobectomy with increasing hospital volume. The adjusted mortality odds for these four procedures in very-high-volume hospitals, relative to very-low-volume hospitals, ranged from .65 to .05. As regards pancreatic resection, after adjustment for patient, clinical, and hospital factors, no statistically significant association was discernible between hospital volume and the likelihood of mortality.

CONCLUSIONS

After adjustment for hospital and physician characteristics, in four of the five procedures, patients treated at higher-volume hospitals had lower in-hospital mortality rates than those treated at lower-volume hospitals. Our findings confirm, for the most part, the hypothesis that better outcomes are associated with higher-volume hospitals.
