Laparoscopic cholecystectomy has emerged as the treatment of choice for uncomplicated cholelithiasis. Despite early concerns, many surgeons have applied this new technique to more complicated biliary tract disease states, including biliary
pancreatitis
. To evaluate the safety of laparoscopic cholecystectomy in this setting, we retrospectively reviewed 29 patients with clinical and laboratory evidence of biliary
pancreatitis
who underwent this procedure between March 1990 and December 1992. The severity of
pancreatitis
was determined by Ranson's criteria. Two patients had a Ranson's score of 6, one of 5, one of 4, five scored 3, nine scored 2, nine also scored 1, and two patients scored 0. The mean serum amylase level on admission was 1,610 (range 148 to 7680). All patients underwent laparoscopic cholecystectomy during the same hospital admission for biliary
pancreatitis
, with the mean time of operation being 5.5 days from admission. Operative time averaged 123 minutes (range 60-220 minutes). Intraoperative cholangiography was obtained in 76 per cent of patients. Three patients had choledocholithiasis on intraoperative cholangiography and were treated with choledochoscopy, laparoscopic common bile duct exploration, and saline
flushing
of the duct. The mean length of hospital stay was 11 days (range 5-32 days). There were seven postoperative complications requiring prolonged hospitalization with all but one treated non-operatively. One patient with a preoperative Ranson score of 6 developed necrotizing
pancreatitis
and subsequently required operative pancreatic debridement and drainage. There were no deaths in this series and no postoperative wound infections. The average recovery period for return to work was 2 weeks. These statistics compare favorably with literature reports for open cholecystectomy in biliary
pancreatitis

To study the efficacy of extracorporeal shock-wave lithotripsy (ESWL) of pancreatic duct stones, seventeen patients (mean age: 42 years) with recurrent attacks of abdominal pain as a result of chronic calcifying
pancreatitis
were treated with this method. In all cases, endoscopic removal of the stones proved impossible. When there was fragmentation, the remaining calculi and fragments either evacuated spontaneously, or attempts were made to extract them endoscopically, followed by
flushing
. In 13 patients (76%), fragmentation of stones was achieved, and 11 of these patients had dramatic pain relief directly after ESWL (65%). However, complete ductal clearance of stones was achieved in only seven patients (41%); at the last follow-up (12-59 months after ESWL, mean: 30 months), all seven were free of symptoms. Of the six patients with stone fragmentation without ductal clearance, three were operated on because of recurrent complaints. The only complication due to the procedure was an exacerbation of
pancreatitis
in one patient, which was treated conservatively. If pancreatic stones cannot be removed endoscopically, ESWL seems to be preferable to surgery, which may still be performed in case of failure. It seems important to achieve ductal clearance and not merely stone disintegration in order to obtain the desired long-term clinical effects.

In this study we present the technical details, adaptations and modifications of the original procedure of pancreaticoduodenal transplantation in rats described by Lee et al. in 1972. We also present the results and technical failures observed in a follow-up of 12 years. From March, 1982 to December, 1994, we performed in the Laboratory of Surgical Technique and Experimental Surgery of Faculty of Medicine, Botucatu-UNESP, Brazil, 665 duodenopancreatectomies in donor rats and 592 surgeries for revascularization of the pancreatic graft in recipient animals. The observed percentage of technical failures in donor rats was 11% due to bleeding and/or vascular complications, irregular
flushing
of the graft with saline and respiratory insufficiency. In recipients of grafts, we observed a percentage of technical failures of 22.5% due to porto-caval thrombosis, vascular bleeding,
pancreatitis
and graft ischemia. In both surgeries, the successful results are directly related to the technical performance of the surgeon and the cares in the postoperative period.

The procurement of a pancreatic graft must be as meticulous as possible and with minimum handling and blood loss so that the transplant procedure can be carried out with no complications. We describe the technique we are using in our institution which, contrary to others, requires that most of the dissection for donor pancreatectomy be done after crossclamping and intravascular
flushing
of the abdominal organs. We have performed 50 consecutive procurements of pancreatic grafts using this technique. All grafts were successfully transplanted with no evidence of post-transplant primary non-function or graft
pancreatitis
. We believe that this technique is faster and minimises handling of the pancreas and blood loss resulting in excellent post-transplant metabolic function of the pancreatic graft.

Our objective was to review our community hospital experience with laparoscopic management of choledocholithiasis from 1991 to 1997. We performed a retrospective review of all case records of patients with choledocholithiasis managed surgically at St. Francis Hospital during the study period. Data regarding the history, presentation, investigations, operative details, and follow-up were recorded. Procedures were performed by multiple attending surgeons supervising surgical residents. All common bile duct explorations (CBDEs) were performed by a transcystic approach and followed routine cholangiography. In most cases, cystic duct dilatation over a guide wire was followed by transcystic CBDE with choledochoscopy. Stone extraction was accomplished through a combination of
flushing
, basket manipulation, fragmentation, retrieval, or advancement of stones through the ampulla. Data were analyzed using SPSS computer software, and P < 0.05 was considered statistically significant. During the period of study there were 1053 laparoscopic cholecystectomies with and without cholangiography and 100 total CBDE performed. Of these, 54/100 had an attempt at laparoscopic CBDE. There were 39 females and 15 males, with a median age of 52 years (range 14-88). Presentation included acute cholecystitis or biliary colic (63%), gallstone
pancreatitis
(20%), and jaundice or cholangitis (17%). Successful laparoscopic stone removal was achieved in 36 of 54 (67%) cases. Eighteen of the remainder (33%) were converted to an open procedure. Size, number, position of stones, technical difficulties in accessing the common bile duct, and patient factors contributed to open conversion. The rate of successful laparoscopic CBDE improved for each individual surgeon from an average of 22 per cent in the first half of the study period (1991-1994) to 87 per cent in the second half (1995-1997). There was no operative mortality. Significant morbidity in the laparoscopic group included one retained stone and two cases of postoperative
pancreatitis
. There were three false negative preoperative endoscopic retrograde cholangiopancreatography examinations. Multivariate analysis showed that experience of the individual surgeon was the only significant factor predicting successful laparoscopic CBDE. Low initial success rate in the early phase of the study period improved dramatically to reach an overall success rate of 87 per cent in the second half. Laparoscopic management of common bile duct stones is possible in a community setting with a high success rate and minimal morbidity. It precludes excessive use of endoscopic retrograde cholangiopancreatography with its own set of complications but is associated with a significant learning curve. It is currently our preferred therapeutic approach for choledocholithiasis discovered pre- or intraoperatively.

Ischemia/reperfusion injury plays an important role in the development of graft
pancreatitis
and thrombosis after pancreas transplantation. Up to now there are few therapeutic options for this severe complication because very little is known about pancreatic ischemia/reperfusion injury. The same pathomechanisms may also be involved in the induction and determination of the course of acute pancreatitis. We observed the effect of 2 h of warm in situ ischemia on the postischemic tissue oxygenation, histological organ damage, and pancreatic enzymes. Experiments were performed in 21 male Wistar rats. In sham-operated animals without ischemia, the pancreas was not dissected. In the ischemia/reperfusion group a pancreatic tail-segment was carefully separated from the head, and ischemia was induced by clamping the splenic vessels for 2 h, after
flushing
the pancreatic tail-segment with heparinized saline. Animals treated similarly, but with opening of the clamps some seconds after induction of ischemia, served as controls. The animals were observed for 2 h after reperfusion. Tissue oxygenation was monitored by a PO2-sensitive probe (LICOX, GMS, Kiel, Germany) which was implanted into the pancreatic tissue. Blood samples were taken before, 5 min, 60 min, and 120 min after reperfusion. At the end of the experiment the pancreatic tail was excised for histological examination; biopsies froin the non-ischemic pancreatic head served as intraindividual control to exclude side effects on the nonischemic pancreatic head. In the ischemia/reperfusion group, PO2ti was significantly lower 1 h (18.0+/-1.7 mmHg) and 2 h (16.4+/-1.6 mmHg) after reperfusion compared with baseline conditions (32.8+/-5.2 mmHg) and the control group (1 h 30.6+/-1.9 mmHg, 2 h 32.4+/-2.4 mmHg). Histological injury score and plasma lipase activity were significantly higher in the ischemia/reperfusion group compared with the control group. Thus we describe a new experimental model of complete normothermic in situ ischemia of a pancreatic tail-segment with the possibility of
flushing
the pancreatic tail-segment and selective local application of drugs to the pancreas.

Catecholamine-secreting metastatic carcinoid should be considered in differential diagnosis of malignant pheochromocytoma. Paroxysmal functioning or hormonally silent gastroenteropancreatic neuroendocrine tumors (GEP NETs) require repeat biochemical measurements and sensitive anatomic and functional imaging studies overlapping those for malignant pheochromocytoma. This report presents clinical, laboratory, and radiologic findings in a patient presenting with heart rate variability; vasoactive headaches reactive to ethanol, tyramine and tryptophan; labile blood pressure; diaphoresis; diarrhea; abdominal pain; unexplained
pancreatitis
; joint pain; and paroxysmal
flushing
with pallor. GI studies (including endoscopic ultrasound) and multiple imaging modalities (including 2D CT, MRI with gadolinium, [18]FDG PET/CT, [123I]MIBG, and SRS [111In]Octreotide [OctreoScan]) were not diagnostic. 24-h BP, Holter and 30-day cardiac event monitors plus urinary biochemical studies consistently suggested catecholamine-synthesizing NET. NIH plasma metanephrines studies and [6]-[18F]Fluorodopamine PET ruled out malignant pheochromocytoma (pheo). Repeated studies showed persistently abnormal GEP NET biomarkers and urinary catecholamines. Capsule endoscopy revealed suspicious submucosal lesions throughout the small intestine. Dual-phase 64-slice multidetector computed tomography (MDCT) with 3D volumetric reconstruction of the abdomen and pelvis revealed multiple diffuse liver metastases and three extrahepatic lesions consistent with metastatic carcinoid. In combination, intensive biochemical testing repeated over time, dual-phase 64-slice MDCT with 3D image reconstruction and volume-rendering (VR) technique, and advanced radionuclide imaging are required to detect NETs' sporadic or paroxysmal functioning, rule out extra-adrenal pheochromocytoma, and localize and characterize metastatic carcinoid. If pheochromocytoma is ruled out, yet symptoms and biochemical markers for catecholamine excess are present, then carcinoid and other amine-precursor-uptake decarboxylation (APUD) tumors must remain in the differential diagnosis.

We reviewed pancreas transplantation outcomes after Histidine-Tryptophan-Ketoglutarate (HTK) and University of Wisconsin (UW) preservation solution use between 2001 and 2007 at two transplant centers. While equivalence has been claimed for kidney and liver transplant outcomes after the use of HTK or UW preservation solution, consensus has not been reached on equivalence when
flushing
pancreata. Others have reported comparable patient and graft survival rates, but found an association between the use of HTK and an increase in the incidence of acute rejection and
pancreatitis
. In reviewing our experiences, we found in pancreata flushed with HTK a higher incidence of postoperative complications including graft
pancreatitis
, use of octreotide and a decreased rate of insulin-independence at hospital discharge. These findings prompted us to critically review our centers' experience to determine if there is a basis for suspecting a causal relationship.

For good performance in clinical and forensic toxicology, it is important to be aware of the signs and symptoms related to xenobiotic exposure since they will assist clinicians to reach a useful and rapid diagnosis. This manuscript highlights and critically analyses clinical and forensic imaging related to ethanol abuse. Here, signs that may lead to suspected ethanol abuse, but that are not necessarily related to liver disease are thoroughly discussed regarding its underlying mechanisms. This includes
