Are reactive C protein and procalcitonin useful for early diagnosis of postoperative intraabdominal infection after pancreaticoduodenectomy for pancreatic cancer?

Objective

To evaluate the relationship between C reactive protein and procalcitonin levels and the appearance of post-operative intraabdominal infection, in patients with pancreaticoduodenectomy due to pancreatic cancer.

Method

A prospective observational study, including 35 patients, was made. Procalcitonin and C reactive protein were measured before surgery, as well as 24, 48 and 72 h after the surgical procedure. Patients were divided in two groups, with and without intraabdominal infection.

Results

Six patients (17.1%) presented post-operative intraabdominal infection. Both, procalcitonin and C reactive protein, increased in all patients after surgery, but there were no significant differences between the two groups. However, the ratio between the C reactive protein concentrations on post-operative day 3 and the concentrations on post-operative day 1 was significantly increased in the group of patients with intraabdominal infection. The predictive positive value and the predictive negative value for this ratio were 60% and 95%, respectively, for a cut-off point of 2.3.

Conclusions

The ratio between C reactive protein value on post-operative day 3 and the value on post-operative day 1 is a good predictor of post-operative intraabdominal infection after pancreaticoduodenectomy.

Esophagogastric pathology in morbid obese patient: Preoperative diagnosis, influence in the selection of surgical technique

INTRODUCTION

Given the difficulty in accessing to the excluded stomach after gastric bypass and the increase in gastroesophageal reflux after sleeve gastrectomy, it is justified to perform a preoperative fibrogastroscopy.The influence of the fibrogastroscopy (FGS) findings in the therapeutic approach is analyzed.

PATIENTS AND METHODS

A retrospective study of preoperative FGS findings is performed, from 04/06 to 12/12. The influence of the FGS results on the surgical technique selection, in the endoscopic or medical treatment and its relation to gastric fistula is analyzed by means of multivariate regression (confounding factors: Age, body mass index, arterial hypertension, diabetes mellitus, antiplatelet therapy, surgical technique (bariatric surgery, sleeve gastrectomy).

RESULTS

Three hundred thirty one patients are included: 32.6% biopsy of gastric lesion; 27% gastritis; 18.1% hiatal hernia; 3% metaplasia; 0.6% Barrett esophagus; 2.1% esophagitis; 0.3% dysplasia; 0.3 Schatzky´s ring; 1.5% incompetent cardia; 2.4% duodenitis; 0.3% gastric erosions; 0.6% gastric xanthoma; 1.8%, gastric polyp; 1.6% duodenal ulcer; 0.6% papulo-erosive gastritis; 0.6% esophageal papilloma; 0.3% submucosal tumor. Helicobacter pylori+ 30.2% (triple therapy eradication in all patients). The FGS findings led to a variation in the surgical technique or to the completion of endoscopic treatment in 22.2% of cases.The gastric lesions did not influence the development of gastric fistula. Independent prognostic factors of fistula: Sleeve gastrectomy (7.9% vs. 2.7%; p = 0.02; OR: 1.38 IC95: 1.01-1.87) and the body mass index > 50 kg/m2) (6.7% vs. 2.2%; p = 0.04; OR: 3.7 IC95: 1.12-12.4).

CONCLUSIONS

The diagnosis of gastroesophageal disease through preoperative FGS motivated variations in the therapeutic approach in 52% of patients, so we consider essential to include the preoperative FGS in bariatric surgery.
