Indwelling double-pigtail plastic stents for treating disconnected pancreatic duct syndrome-associated peripancreatic fluid collections: long-term safety and efficacy.

BACKGROUND: Long-term transmural double-pigtail stent (DPS) placement is recommended for patients with disconnected pancreatic duct syndrome (DPDS) and peripancreatic fluid collections (peri-PFCs). The long-term safety and efficacy of indwelling DPSs were evaluated. METHODS: Medical files of patients treated with DPS for DPDS-associated peri-PFC and with a follow-up ≥ 48 months were reviewed. Early ( < 30 days) and late complications of DPS placement were evaluated and the primary endpoint, i. e., incidence of late complications per 100 patient-years of follow-up, was calculated. Short- and long-term success rates of endoscopic treatment and rate of peri-PFC recurrence were among secondary endpoints. RESULTS: From 2002 to 2014 we identified 116 patients, with mean (SD) follow-up of 80.6 (34.4) months. Among early complications (n = 20), 6 occurred peri-interventionally. Late complications (n = 17) were mainly pain due to DPS-induced ulcer or erosion (n = 10) and 14 of these were treated conservatively or by stent removal; 2 gastro-pancreatico-colo-cutaneous fistulas and 1 persisting bleed required surgical intervention. No DPS-related deaths were recorded. The incidence rate (95 %CI) of late complications was 2.18 (1.27-3.49) per 100 patient-years of follow-up. Short- and long-term success rates (with 95 %CI) of endoscopic treatment were 97.4 % (94.5 %-100 %) and 94 % (89.6 %-98.3 %), respectively. The peri-PFC recurrence rate was 28 % (20.1 %-35.9 %), and 92.3 % of these occurred within the first 2 years. Stent migration, chronic pancreatitis, and length of stent (> 6 cm) were independently associated with higher rates of peri-PFC recurrence. CONCLUSIONS: Long-term transmural drainage with DPS is a safe and effective treatment for DPDS-associated peri-PFCs. However, about one quarter of peri-PFCs will recur.

Endovascular Management of Extra-Peritoneal Hematoma Secondary to Bladder Catheterization.

Bladder rupture related to Foley catheter insertion is a rare condition mainly reported in patients with chronic bladder disease. In the present case, this rare condition was associated with massive hematoma due to active arterial bleeding, which was treated by embolization. We present the case of a 38-year-old woman admitted to the gastroenterology department with decompensated alcoholic liver cirrhosis, anemia, malnutrition, and diabetes. Six days after admission, she presented with hypotension and tachycardia associated with gross hematuria. An abdominal computed tomography scan revealed a Foley catheterization-related bladder perforation and a massive extra-peritoneal hematoma caused by active arterial bleeding from a distal branch of the right vesical artery. A successful embolization was performed with microparticles and coiled with complete hemorrhage control on post-procedure imaging. The bladder perforation was treated conservatively with a urinary drainage catheter, irrigation, and antibiotics. Despite these measures, the patient died 15 days later due to liver failure and sepsis. Our case highlights that commonly performed simple procedures can lead to severe complications, especially in frail patients.
