Endoscopic ultrasound-guided drainage of abdominal fluid collections after pancreatic surgery: Efficacy and long-term follow-up.

BACKGROUND/PURPOSE: Endoscopic ultrasound-guided drainage (EUS-GD) of postoperative abdominal fluid collections (POFC) following pancreatic surgery is used as an alternative or complement to percutaneous drainage (PD) procedure. The present single-center retrospective study evaluates its efficacy and safety. METHOD: We included consecutive cases with POFC treated by EUS-GD between September 2009 and November 2014 in our department. Technical success, long-term clinical success, recurrence rate and need for surgery were analyzed. RESULTS: 24 procedures in 20 patients (95 % after pancreatic resection) were assessed. Indications for surgery included tumors/lesions located in the pancreas (15/20), chronic pancreatitis (3/20) and duodenal adenoma not completely resectable endoscopically (2/20). EUS-GD was performed within a median of 30 days (IQR: 8.25) for a median fluid collection size of 72.5 mm (IQR: 46.25), requiring a mean of 1.2 sessions with placement of a mean of 2.1 plastic stents (7 Fr/10 Fr) per patient for a mean of 89 days (IQR: 127). Microbiology of aspirated fluid revealed positive cultures in 13 patients, mostly polymicrobial, isolated positive for fungal and 3 multidrug-resistant gram negative (MRGN) in 4 cases. An additional transpapillary drainage was inserted in 1/20 patients. 4/20 patients received PD, mostly before EUS-GD. Technical and clinical success was achieved in 20/20 (100 %) and 18/20 (90 %) patients, respectively, while 2 patients required re-operation. During follow-up (median 630 days after stent removal, range: 45 - 2160), recurrence occurred in 1/18 (5.5 %) patient that was referred for surgery. No death or severe adverse events were noted. CONCLUSION: EUS-GD is an effective, minimally invasive and safe method for therapy of POFC after pancreatic surgery offering long-term remission in about 95 % of cases.

[Klatskin tumors: rational diagnostics and staging]. / Klatskin-Tumoren: rationale Diagnostik und Staging.

Klatskin tumors continue to be a challenge for diagnostic assessment and staging due to their longitudinal tumor growth along the perihilar bile ducts. Therefore the rate of non-resectable tumors remains relatively stable despite modern imaging and endoscopic techniques. This article reviews the current diagnostic methods for preoperative staging and the significance for predicting resectability.

Terlipressin in 30 patients with hepatorenal syndrome: results of a retrospective study.

Terlipressin is known to improve renal function in patients with liver cirrhosis and hepatorenal syndrome (HRS). This study investigated effects of duration and dose of terlipressin therapy and predictive factors for positive response to treatment. The clinical charts of 30 consecutive patients with HRS who received terlipressin and albumin based on a determined therapeutic scheme, were retrospectively studied. In 25 (66 %) of 38 treatment episodes complete response was achieved (Kaplan-Meier survival method). Predictive for positive response to treatment were duration of treatment and cumulative terlipressin dosis (p < 0.01, 95 % CI 0.31 - 0.59 and p < 0.01, 95 % CI 0.93 - 0.98, respectively) as well as a low level of serum creatinine and MELD score at inclusion (p = 0.01, 95 % CI 0.3 - 9.85 and p < 0.01, 95 % CI 0.87 - 0.98 respectively) and HRS type II (p = 0.04, 95 % CI 1.04 - 9.93). The median duration of therapy was 6 days +/- 4.9 (SD) vs. 8 days +/- 6.3 in the nonresponder group. The median dose of terlipressin in the responder group was 3.9 mg +/- 1.3 per day vs. 3.4 mg +/- 1.4 in the nonresponder group (p = n. s.). The probability that complete response was obtained at day 17 of treatment was 84 % (95 % CI 0.64 - 0.96), whereas at day 7 it was just 52 % (95 % CI 0.36 - 0.7). In conclusion, these data confirm that terlipressin plus albumin is effective in two-thirds of patients with HRS. Prolongation of treatment beyond 7 days up to 20 days is capable of increasing the response rates. Whether outcome can be predicted depending on parameters like type of HRS and base-level of serum creatinine needs to be confirmed in further studies, especially with regard on the previously revised criteria of HRS.
