Course of Acute Pancreatitis Patients with Renal Failure According to Balthazar Classification

Background and Aim

There are criteria that include many organ systems to predict the prognosis in acute pancreatitis (AP) patients. In this study, we aimed to show how the course of the disease changes according to the Balthazar classification in AP patients presenting with renal failure.

Methods and Materials

Our study included 352 patients who were admitted to the Emergency Service of our hospital and were diagnosed and hospitalized with AP. According to the Balthazar score, patients with scores of 0-2, 4-6, and 8-10 were evaluated as mild, moderate, and severe AP, respectively. Demographic data (age, gender) of all patients were documented. The etiology of AP was determined in all patients. Biliary, drug/toxic, alcohol, infections, hyperlipidemia, post-endoscopic retrograde cholangiopancreatography (ERCP), genetics, hypercalcemia, structural anomalies, and malignancy were evaluated as the etiology. Those without any underlying pathology were evaluated as idiopathic AP. The patients were divided into two groups as those with and without renal insufficiency. All patients underwent helical computed tomography (section 64, Aquilion; Toshiba Medical Systems, Tokyo) within the first 12 hours and between days 3 and 7. Pancreas, peripancreatic and extrapancreatic findings, and complications were examined. "The Statistical Package for the Social Sciences 19.0 (SPSS Armonk, NY: IBM Corp.)" was used for all analyses. Kolmogorov-Smirnov test and histograms were used to determine whether there was a normal distribution. The non-parametric data of the groups were compared using the Mann-Whitney U test and the parametric data using the ındependent t test. Chi-square test was used to test categorical data. Cases with P < 0.05 were considered statistically significant.

Results

: While 22 (6.2%) patients had renal insufficiency, 332 (95.8%) patients did not have renal insufficiency. In the evaluation made in terms of AP severity; according to Balthazar classification at admission, there was no difference in mild and moderate pancreatitis for kidney insufficiency in both groups, but it was significantly higher in the group with severe pancreatitis [2 (9.1%) versus 1 (0.3%), P < 0.001]. In the evaluation made after 72 hours; renal failure was significantly lower in the group with mild pancreatitis [11 (50.0%) versus 245 (73.8%), P: 0.016] and severe renal failure was significantly higher in severe pancreatitis [7 (31.8%) versus 13 (%) 3.9), P < 0.001].

Conclusions

Early intensive care unit admission and close follow-up and early treatment in AP patients change the course of the disease. In our study, we showed that serum creatinine level is an important parameter in the course of AP and has a predictive value for the course of the disease.

Metallic stent in the endoscopic treatment of pancreatic fluid collections

BACKGROUND AND AIMS

The endoscopic treatment of pancreatic fluid collections (PFCs) has become the preferred first-line approach. Fully covered self-expandable metal stents (FCSEMS) were considered as an alternative to multiple double pigtail stents. The aim of this study was to evaluate the results of the endosonography guided drainage (EUS-GD) of PFCs with FCEMS.

MATERIALS AND METHODS

A total of 33 consecutive patients were included. Cystogastrostomy and cystoduodenostomy were created with a linear echoendoscope under endosonographic and fluoroscopic control. Procedures were performed in a standard way of, puncture with a 19 gauge needle, bougie dilation and insertion of FCSEMS.

RESULTS

A total of 33 patients (mean age 52 years, 21 men, range: 18-77 years), were included. PFCs were 22 non-infected symptomatic pseudocyst and 11 walled-off necrosis or abscess. EUS-GD was successful in 30 (90.9%) patients. Stent insertion failed in one patient. Two patients needed surgery. Complications were observed in 8 (25%) patients (stent dislocation in 3, perforation in 2, bleeding in 2 and pneumoperitoneum in 1 patient). Procedure related mortality was not seen. The mean cyst size was 11.3 cm (5-22). FCSEMS were successful in the treatment of pseudocysts (after 1 month mean cyst size is 6.2 cm, range: 0-15 cm, with 54.8% decrement rate). During a mean follow-up of 15 months complete resolution was 66.6% (20 patients) and recurrence due to stent malfunction was 10%. All these cases were submitted to a new session of endoscopic drainage.

CONCLUSIONS

EUS-GD, FCSEMS insertion provides an effective, minimally invasive, and safe approach in the management of PFCs.
