ABSTRACT To compare the efficacy of endoscopic retrograde cholangiopancreatography +/- endoscopic sphincterotomy (ERCP +/- ES) versus traditional conservative management in early gallstone pancreatitis with persistent ampullary obstruction (GSP + AO).
The effectiveness of early ERCP +/- ES in this setting is controversial.
Sixty-one consecutive patients with GSP + AO within 48 hours from the onset of symptoms were randomized to receive either conservative treatment and selective ERCP +/- ES after 48 hours (control group, 31 patients) or initial conservative treatment and systematic ERCP +/- ES within 48 hours if obstruction persisted 24 hours or longer (study group, 30 patients). Patient outcome was compared in relation to treatment groups and to duration of obstruction.
In the control group, 22 patients disobstructed spontaneously within 48 hours; 3 of the remaining 9 patients underwent ERCP +/- ES and none had impacted stones. In the study group, 16 patients disobstructed spontaneously and 14 underwent ERCP within 48 hours from the onset of symptoms; impacted stones were found and extracted by ES in 79% (11 of 14) of these.
There were no deaths in either group. Patients in the study group showed a shorter period of obstruction (P = 0.016) and a lower rate of immediate complications (P = 0.026) than controls. Patients with obstruction lasting < or =48 hours regardless of the treatment group had fewer immediate complications than those whose obstruction persisted longer (P < 0.001).
This study shows that in patients with GSP + AO limiting the duration of obstruction to not longer than 48 hours by ERCP + ES decreased morbidity.

    ABSTRACT: Hepatopancreatobiliary (HPB) emergencies include an ample range of conditions with overlapping clinical presentations and diverse therapeutic options. The most common etiologies are related to cholelithiasis (acute cholecystitis, pancreatitis, and cholangitis) and non-traumatic injuries (common bile duct or duodenal). Although the true incidence of HPB emergencies is difficult to determine due to selection and reporting biases, a population-based report showed a decline in the global incidence of all severe complications of cholelithiasis, primarily based on a reduction in acute cholecystitis. Even though patients may present with overlapping symptoms, treatment options can be varied. The treatment of these conditions continues to evolve and patients may require endoscopic, surgical, and/or percutaneous techniques. Thus, it is essential that a multidisciplinary team of HPB surgeons, interventional gastroenterologists and radiologists are available on an as needed basis to the Acute Care Surgeon. This focused manuscript is a contemporary review of the literature surrounding HPB emergencies in the context of the acute care surgeon. The main aim of this review is to offer an update of the diagnosis and management of HPB issues in the acute care setting to improve the care of patients with potential HPB emergencies.

    ABSTRACT: Gallstone disease is the most common cause of acute pancreatitis in the Western world. In most cases, gallstone pancreatitis is a mild and self-limiting disease, and patients may proceed without complications to cholecystectomy to prevent future recurrence. Severe disease occurs in about 20% of cases and is associated with significant mortality; meticulous management is critical. A thorough understanding of the disease process, diagnosis, severity stratification, and principles of management is essential to the appropriate care of patients presenting with this disease. This article reviews these topics with a focus on surgical management, including appropriate timing and choice of interventions.

    ABSTRACT: To define a therapeutic program for mild-moderate acute pancreatitis (AP), often recurrent, which at the end of the diagnostic process remains of undefined etiology. In the period 2011-2012, we observed 64 cases of AP: 52 mild-moderate, 12 severe; biliary 39, biliary in alcoholic chronic pancreatitis 5, unexplained recurrent 20. The clinical and instrumental evaluation of the 20 cases of unexplained AP showed 6 patients with biliary sludge, 4 microlithiasis, 4 sphincter of Oddi dysfunction, and 6 cases that remained undefined. Among 20 patients with recurrent, unexplained AP at initial etiological assessment, we performed 10 video laparo cholecystectomies (VLCs), 2 open cholecystectomies and 4 endoscopic retrograde cholangiopancreatography/endoscopic sphincterotomies (ERCP/ES) in patients who had undergone previous cholecystectomy; 4 patients refused surgery. Among these 20 patients, 6 had AP that remained unexplained after second-level imaging investigations. For these patients, 4 VLCs and 2 ERCP/ES were performed. Follow-up after six months was negative for further recurrence. The recurrence of unexplained acute pancreatitis could be treated with empirical cholecystectomy and/or ERCP/ES in cases of previous cholecystectomy.
