Disconnected Pancreatic Duct Syndrome: Endoscopic Stent or Surgeon's Knife?

Disconnected pancreatic duct syndrome is a sequela of necrotizing pancreatitis or pancreatic trauma in which necrosis of a segment of the pancreas leads to lack of continuity between viable secreting pancreatic tissue (eg, body or tail) and the gastrointestinal tract. The endoscopic retrograde cholangiopancreatography showing total cutoff of the pancreatic duct along with an enhancing distal pancreas on contrast-enhanced computed tomography remains the criterion standard for diagnosis. Recently, the evolving literature supports a role for magnetic resonance cholangiopancreaticography, especially with secretin stimulation. A multidisciplinary approach is extremely important in the management of this condition. Conservative measures are usually not helpful, and interventional radiology, endoscopic, or surgical intervention is almost always needed for management of these patients. Recently, endoscopic ultrasonography-guided drainage procedures in conjunction with endoscopic retrograde cholangiopancreatography-assisted pancreatic duct stenting have emerged as a novel technique to manage this condition. The aim of this review was to give a detailed overview about the diagnosis and management of disconnected pancreatic duct syndrome with emphasis on the changing paradigm in endoscopic and surgical management.

Splanchnic vein thrombosis in acute pancreatitis: a single-center experience.

OBJECTIVES: This study aimed to estimate outcomes of splanchnic vein thrombosis (SVT) in hospitalized patients with acute pancreatitis (AP). METHODS: This was a retrospective study (January 1996 to December 2006) via chart review. RESULTS: Over 10 years, 1.8% (45/2454) of patients with AP with a mean (SD) age of 58 (15) years were diagnosed with SVT. Splenic vein thrombosis was the most common form of SVT (30/45 patients, 67%). Seventeen patients were anticoagulated with heparin, when the SVT was diagnosed in the acute stage followed by oral anticoagulation (AC). The thrombosis that was most commonly anticoagulated was portal vein thrombosis in 11 (65%) of 17 patients. Of 17 patients in the AC group, 2 (12%) showed recanalization as compared with 3 (11%) of 28 patients in the non-AC group (P > 0.05). The mortality was 3 (7%) of 45 (2 from the AC group versus 1 in the non-AC group, P > 0.05). Two of these died of multiorgan failure, and the other, from septic shock. None of the deaths were due to bleeding complications. CONCLUSIONS: Splanchnic vein thrombosis occurred in 1.8% patients of AP. The use of AC was reasonably safe with no fatal bleeding complications. However, there was no significant difference in the recanalization rates in those with and without AC.

Successful outcome with conservative management of emphysematous pancreatitis.

OBJECTIVES: Surgery is the mainstay treatment of emphysematous pancreatitis (EP). The aim of the present study was to assess the outcomes of patients with EP managed nonsurgically. METHODS: The patients with EP without organ dysfunction were managed nonsurgically with antibiotic therapy, nutritional support, and if required radiological drainage. The main outcome measure was survival. RESULTS: Nine patients were diagnosed with EP. They had computed tomographic severity index of 10, APACHE score of 11 (±3.4), and Ranson's score of 4.2 (±1.2) in the first 24-48 h. All had monomicrobial infection of the pancreatic necrosis (Escherichia coli in 4/9, Pseudomonas aeruginosa in 3/9, and Klebsiella pneumoniae in 2/9 patients). All these patients were managed with antibiotics as per sensitivity reports (piperacillin-tazobactum in 5/9, imipenem in 3/9, and ciprofloxacin-metronidazole in 1/9 patients) and nutritional support. Seven of nine patients improved within 1 week of starting antibiotics. Two patients required percutaneous catheter drainage in addition. One of the patients had progressive organ dysfunction and was subjected for surgery. All 8/9 patients who were managed conservatively survived (89 % survival). The only patient who underwent surgery expired (11 % mortality). CONCLUSION: In EP without organ dysfunction, a trial of conservative management may be successful.

Splanchnic venous thrombosis and pancreatitis.

Pancreatitis is an inflammatory process with local and systemic manifestations. One such local manifestation is thrombosis in splanchnic venous circulation, predominantly of the splenic vein. The literature on this important complication is very sparse. This review offers an overview of mechanism of thrombosis, its pathophysiology, diagnosis, and management in the setting of acute as well as chronic pancreatitis.

Diastolic dysfunction, prolonged QTc interval and pericardial effusion as predictors of mortality in acute pancreatitis.

BACKGROUND AND AIM: The cardiac changes in acute pancreatitis have been earlier studied but the data on their prognostic significance is limited. This study was done to determine electrocardiographic (ECG) and echocardiographic changes in acute pancreatitis and determine their prognostic significance. METHODS: Fifty-two consecutive patients (mean age 36.5 ± 11 years (44 males)) with acute pancreatitis and without prior cardiovascular comorbidites were prospectively enrolled and subjected to clinical, laboratory and radiological investigation. ECG and echocardiography was done at admission and during follow up. RESULTS: Seventeen patients (32.7%) had mild pancreatitis and 35 (67.3%) patients had severe pancreatitis. Sinus tachycardia was the most common ECG abnormality. QTc prolongation was seen in 30/52 (57.7%) patients. On echocardiography, no patient had systolic dysfunction but 31/52 (59.6%) patients had diastolic dysfunction. All 22 patients with QTc interval < 440 ms survived compared with 8/30 patients with QTc interval ≥ 440 ms who died (P = 0.01). All eight patients who died had evidence of diastolic dysfunction (100%). None of the patients without diastolic dysfunction succumbed to illness (P = 0.02). Pericardial effusion was present in 6/52 (11.5%) patients. Of the eight patients who died, pericardial effusion was present in three (37.5%) patients and this frequency was significantly higher than that in patients who recovered (3/44 [6.8%]; P = 0.04). CONCLUSION: Electrocardiographic and echocardiographic changes are seen in more than 50% of patients with acute pancreatitis. Prolonged QTc interval, pericardial effusion and diastolic dysfunction are associated with higher mortality.

Neuroendocrine tumors of the ampulla of vater: presentation, pathology and prognosis.

CONTEXT: Neuroendocrine tumors of the pancreatic ampulla are uncommon. The final diagnosis is based on histology, and at times, it may be difficult to diagnose them pre-operatively since they present with a similar clinical picture to adenocarcinomas of this region. OBJECTIVE: To identify neuroendocrine tumors of the ampulla, as well as their presentation and management. DESIGN: A retrospective review of patients treated at a tertiary care institute was performed over a six-year period from 2005 to 2010. PATIENTS: Cases with periampullary cancers were investigated. MAIN OUTCOME MEASURES: The case records were scrutinised for the clinical presentation, management and outcomes. RESULTS: A total of 4 cases (7.7%) of neuroendocrine tumors of the ampulla were identified from 52 patients with periampullary lesions, at a mean age of presentation of 49 years. The common mode of presentation was progressive jaundice (3 of 4 patients); pancreaticoduodenectomy was performed in 3 patients. One patient underwent palliative endoscopic stenting for metastatic disease. On histopathology, 2 of the patients had poorly differentiated (neuro)endocrine carcinoma (high grade), and 2 had well differentiated (neuro)endocrine carcinoma (1 low grade and 1 intermediate). All the tumors stained positively with chromogranin A. The patients who underwent pancreaticoduodenectomy are on regular follow-up and remain free of disease. CONCLUSIONS: Neuroendocrine tumors of the ampulla are distinct entities presenting clinically with jaundice. They stain positive with chromogranin A on histopathology. Pancreaticoduodenectomy should be performed as it is associated with good outcome.

Salvage Surgery in Endoscopic Era.

Common bile duct stones are usually managed by Gastroenterologists using Endoscopic Retrograde Cholangiopancreaticography (ERCP) and services of Surgeons are required if the stone is large or impacted. But at times, emergency bile duct explorations become mandatory in some unusual complications of ERCP. We describe one such situation of impacted dormia basket during ERCP which required rescue surgery.

Endoscopic examination of the upper esophagus by withdrawal of endoscope over guide wire.

Upper gastrointestinal (UGI) endoscopy is an important diagnostic modality in evaluation of patients with upper gastrointestinal (GI) disorders. However, lesions located in the cricopharyngeal area and upper esophagus can be missed, as this area may not be well visualized during endoscopy. This study was conducted to study the utility of a new technique of endoscopic examination of the upper esophagus by withdrawal of endoscope over guide wire in diagnosing esophageal disorders. Patients with suspected upper esophageal disorders on history and radiological investigations were assessed using guide wire assisted endoscopic examination during withdrawal of the endoscope. In this technique, endoscope is inserted into the esophagus under vision and thereafter the whole of esophagus, stomach and proximal duodenum is examined. The endoscope is then withdrawn into the mid-esophagus, a guide wire is fed into the biopsy channel, and thereafter inserted into the esophagus. Once guide wire has been advanced into the esophagus, the endoscope is withdrawn gently over the guide wire into esophagus carefully examining for lesions in upper esophagus and cricopharyngeal area. Twenty cases of various abnormalities localized to the upper esophagus were studied. The final diagnosis in these patients was cervical esophageal web (10), post transhiatal esophagectomy leak (4), heterotopic gastric mucosa (3), posttraumatic esophageal perforation (2), and Zenker's diverticulum (1). Intact web was detected in 2 patients and in 8 patients fractured web was seen. Guide wire assisted examination of upper esophagus improved the ability to visualize and characterize these lesions and no complications were encountered as a result of this procedure. Endoscopic examination of the upper esophagus by withdrawal of endoscope over guide wire is safe and effective in diagnosing anatomical abnormalities of the upper esophagus that may be missed or poorly characterized during standard endoscopy.

An intra-hepatic pancreatic pseudocyst successfully treated endoscopic transpapillary drainage alone.

CONTEXT: An intra-hepatic pseudocyst is a very rare complication of acute and chronic pancreatitis with less than thirty cases described in the literature. Successful resolution of intra-hepatic pseudocysts with endoscopic transpapillary nasopancreatic drain placement has not previously been described. CASE REPORT: We report the case of a 34-year-old male with chronic idiopathic non-calcific pancreatitis, anomalous pancreatobiliary junction and a large intra-hepatic pancreatic pseudocyst along with a large abdominal pseudocyst who was successfully treated by endoscopic transpapillary nasopancreatic drainage alone. CONCLUSION: Pancreatic pseudocysts can present as intra-hepatic cystic lesions and communicating intra-hepatic pseudocysts can be successfully treated by endoscopic transpapillary nasopancreatic drainage alone.
