Cholecystostomy for decompression and drainage of the biliary tree is indicated when the elderly, poor risk patient with destructive inflammatory process in the gallbladder is unable to tolerate a more extensive operation. Cholecystostomy is often criticized as an inferior operation, because it provides some palliation but leaves the patient with most problems unattended. To re-evaluate the role of cholecystostomy in the management of
acute disease
of the gallbladder, we reviewed our experience with it. During the years 1974 to 1987, 37 patients underwent a cholecystostomy. Patients ranged in age from 58 to 90 years, with an average age of 69 years. Twenty-eight patients had acute destructive cholecystitis, usually complicated by perforation, peritonitis or ascending cholangitis. Five had severe
pancreatitis
; three, cholelithiasis, and one patient, carcinoma of the bladder. Twenty-seven of the 37 patients had severe systemic disease and were critically ill. At the operation, calculi were extracted and the gallbladder and abscess were drained. Two patients died, yielding a mortality rate of 5.4 per cent. Tube cholangiography was done in 33 patients. Although residual stones were demonstrated in seven patients, the stones were removed electively at a later date under much more favorable conditions. None of the 35 survivors had symptoms of disease of the gallbladder during the follow-up period, which ranged from one to 12 years. Cholecystostomy is a curative operation indicated in critically ill and elderly patients for whom extensive operation is a prohibitive risk.

The correlation between clinical course, protease inhibitors, complement and kinin activation was studied in vivo in 27 attacks of acute pancreatitis and also in vitro. The value of peritoneal lavage was retrospectively analyzed in 73
pancreatitis
attacks. The effect of aprotinin was studied in vitro. Complement and kinin activation occurred in vitro when alpha-macroglobulin (alpha 2-M) concentration was below 35%, in spite of 90% free and reactive alpha 1-protease inhibitor. These low alpha 2-M levels were found in the general circulation in severe attacks. Functional alpha 2-M levels were lower than electroimmunoassay values during the
acute disease
. Complement and kinin activation was present both in blood and in peritoneal fluid. The extent of activation was closely correlated to the severity of the
pancreatitis
attack. Classical as well as alternative complement activation occurred. Kinin activation was caused by plasma kallikrein as well as by other kininogenases. Functional kallikrein inhibition was lower than electroimmunoassay values for the C1 inactivator. High levels of activated trypsin was found in complex with alpha 1-protease inhibitor in severe attacks. These findings together with the low functional alpha 2-M and a possible functional deficiency also of the C1 inactivator make trypsin-induced activation of the complement as well as the kinin system possible in acute pancreatitis. Changes in proteases and protease inhibitors were most pronounced in the peritoneal fluid, functional alpha 2-M and C1 inactivator being zero, indicating that the primary event occurs locally in and around the pancreas. Peritoneal lavage thus ought to be beneficial. The good results achieved with peritoneal lavage in the retrospective analysis of the 73 clinically severe attacks seem to verify this conclusion. The biochemical changes seen in vivo indicate alpha 2-M and C1 inactivator to be most important against proteolytic activation of the complement and kinin systems. Treatment with purified protease inhibitors might be beneficial. This also seems to be true of aprotinin, according to the in vitro results, provided very high doses are used. All antiprotease therapy seems to be most important intraperitoneally.

Laparoscopic cholecystectomy (LCCY) has become the treatment of choice for patients undergoing elective CCY. Inner-city hospitals treat a large number of patients with advanced or
acute disease
, and the ability to perform LCCY in this patient population is unclear. The records of the first 107 patients undergoing LCCY were reviewed. There were 96 women and 11 men with a mean age of 42 years (range 14-86 years). Twenty-seven (42%) of the patients were admitted through the emergency room and were operated upon urgently, whereas 35 (58%) underwent elective LCCY. More than two-thirds of the patients were either uninsured or covered by Medicaid. In the urgent group, 38% had gallstone
pancreatitis
, 41% had abnormal LFTs, and 26% had a WBC > 13,000. A total of 70% of these patients were discharged within 48 hours after LCCY. The conversion rate was 9% and was similar between urgent and elective LCCY. In summary, acute biliary tract pathology accounted for one-half of the patients undergoing LCCY in our hospital. In conclusion, LCCY can be performed in this group of patients with low morbidity, especially if the need for liberal conversion to open CCY is recognized.

Medical records and histologic sections of 40 cats with acute pancreatitis were reviewed. Two distinct groups of cats with
pancreatitis
were established by histologic analysis of tissue. Group 1 (32 cats) had acute pancreatic necrosis (APN). Group 2 (8 cats) had suppurative
pancreatitis
. Ages of affected cats ranged from 3 weeks to 16 years. The majority consisted of indoor cats of the Domestic Short-Haired breed but Siamese cats were over-represented relative to the general population (P < 0.05). Twenty-two percent of cats were obese and 57% were underweight. Thirty-eight percent of cats had
acute disease
. In the other cats, two stages in the progression of the disease were evident: (1) anorexia, weight loss, and lethargy, followed by (2) acute deterioration, development of shock, and a moribund state, despite fluid therapy. The most common clinical signs were severe lethargy (100%), reduced appetite (97%), dehydration (92%), and hypothermia (68%). The initial hemogram occasionally showed a neutrophilia (30%) and anemia (26%) but packed cell volume (PCV) decreased markedly to the extent that 55% of cats were anemic terminally. Serum biochemical abnormalities included increased activities of ALT (68%) and ALP (50%), and increased concentrations of bilirubin (64%) and cholesterol (64%). Cats with APN were hyperglycemic (64%), glycosuric (60%) and ketonuric (20%), whereas cats with suppurative
pancreatitis
tended to be hypoglycemic (75%). Renal failure and electrolyte abnormalities were mild or infrequent except for hypokalemia (56%). This study characterizes a severe necrotizing
pancreatitis
in the cat similar to that reported in other species, and a histologically distinct suppurative
pancreatitis
.

Ninety-nine patients with acute pancreatitis in whom body mass index (BMI = weight (kg)/height2 (m2)) was measured were studied prospectively to determine the importance of obesity as a prognostic factor in this disease. Of 19 obese patients (BMI > or = 30 kg/m2), 12 developed severe
pancreatitis
; seven had abscesses, of whom five died, and two further patients died. In 80 non-obese patients, the incidence of severe
pancreatitis
(n = 5), abscess formation (n = 4) and death (n = 4) was significantly less (P = 0.0007). The mean(s.d.) BMI of 17 patients with severe acute pancreatitis was significantly higher than that in 82 patients with mild
acute disease
(31.2(5.6) versus 23.3(5.6) kg/m2, P < 0.001). As a single prognostic factor, obesity had a sensitivity of 63 per cent and a specificity of 95 per cent for predicting disease severity. When five obese women with gallstone
pancreatitis
were excluded, the sensitivity of obesity increased to 86 per cent. Severe
pancreatitis
occurred in all eight obese patients with disease of an alcoholic aetiology. These data suggest that increased fat deposits in the peripancreatic and retroperitoneal spaces in obese patients may increase the risk of peripancreatic fat necrosis, abscess and death. Consideration should be given to including obesity as a prognostic factor in acute pancreatitis.

Laparoscopic cholecystectomy is a minimally invasive procedure in which the gallbladder is removed. Patients with symptomatic gallstones or biliary dyskinesis are eligible for this procedure. No specific contraindications exist except for poor surgical risk factors. The rate of conversion to an open technique is increased in patients with
acute disease
,
pancreatitis
, bleeding disorders, unusual anatomy, and prior upper abdominal surgery. Complications occur even with experienced laparoscopists, and the important technical aspects of surgery have been identified. The length of the hospital stay and postoperative recovery time is markedly shortened compared with that of standard cholecystectomy. This procedure offers sufficient advantages to patients that it has become the standard of practice in most cases.

Management of biliary disease in the octogenarian has evolved over the last decade. Laparoscopic cholecystectomy is now more commonly performed in this patient population. Octogenarians with biliary pathology frequently present with complications of
acute disease
such as biliary
pancreatitis
, choledocholithiasis, and acute cholecystitis. As a result, laparoscopic management in this patient population can frequently be more challenging than in younger patients. We retrospectively reviewed 70 patients who were 80 years of age and older who underwent cholecystectomy at our institution for biliary tract disease. Seventeen patients presented to the Day Surgery unit for elective management of chronic biliary disease. Sixteen (94%) of these patients were attempted laparoscopically and one (6%) underwent open cholecystectomy. Two patients attempted laparoscopically were converted to open surgery (conversion rate 12.5%). Average length of hospital stay was 3.7 days for those treated laparoscopically and 11 days for patients treated with open cholecystectomy. There were three complications (19%) in this group and no deaths. The remaining 53 patients presented via the emergency room with acute complications of cholelithiasis. Laparoscopic cholecystectomy was attempted in 28 (52%) and open cholecystectomy was performed in 25 (48%) patients. Ten (37%) of the patients attempted laparoscopically were converted to an open procedure. Average length of stay in this group was 11.7 days for those treated laparoscopically and 15.7 days for patients managed with open technique. There were ten (56%) complications in the laparoscopic group and five (14%) complications in the open group. There were four deaths (22%) among those treated laparoscopically and three deaths (8.6%) in the open cholecystectomy group. Comorbid conditions were common in the patients with acute biliary pathology and those presenting for elective cholecystectomy. Laparoscopic cholecystectomy is the procedure of choice in the elective management of biliary tract disease in the octogenarian. Laparoscopic cholecystectomy has no benefit with respect to morbidity and mortality over open cholecystectomy in the management of acute biliary tract disease in this elderly population. When possible, chronic cholecystitis in the elderly should be managed with elective laparoscopic cholecystectomy rather than waiting for complications to develop.

Whether acute recurrent
pancreatitis
is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent
pancreatitis
. There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent
pancreatitis
(ARP) seem a casual association. Cystic fibrosis transmembrane conductance regulator (CFTR) gene mutation, hereditary and obstructive
pancreatitis
seem an
acute disease
that progress to chronic pancreatitis, likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis. From the diagnostic point of view, in patients with acute recurrent
pancreatitis
Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

The role of obesity in relation to various disease processes is being increasingly studied, with reports over the last several years increasingly mentioning its association with worse outcomes in
acute disease
. Obesity has also gained recognition as a risk factor for severe acute pancreatitis (SAP).The mortality in SAP may be as high as 30% and is usually attributable to multi system organ failure (MSOF) earlier in the disease, and complications of necrotizing
pancreatitis
later [9-11]. To date there is no specific treatment for acute pancreatitis (AP) and the management is largely expectant and supportive. Obesity in general has also been associated with poor outcomes in sepsis and other pathological states including trauma and burns. With the role of unsaturated fatty acids (UFA) as propagators in SAP having recently come to light and with the recognition of acute lipotoxicity, there is now an opportunity to explore different strategies to reduce the mortality and morbidity in SAP and potentially other disease states associated with such a pathophysiology. In this review we will discuss the role of fat and implications of the consequent acute lipotoxicity on the outcomes of acute pancreatitis in lean and obese states and during acute on chronic pancreatitis.

Hepatic and pancreatic stellate cells may or may not be regarded as stem cells, but they are capable of remarkable transformations. There is less information about stellate cells in the pancreas than in the liver, where they were discovered much earlier and therefore have been studied longer and more intensively than in the pancreas. Most of the work on pancreatic stellate cells has been carried out in studies on cell cultures, but in this review we focus attention on Ca(2+) signalling in stellate cells in their real pancreatic environment. We review current knowledge on patho-physiologically relevant Ca(2+) signalling events and their underlying mechanisms. We focus on the effects of bradykinin in the initial stages of acute pancreatitis, an often fatal disease in which the pancreas digests itself and its surroundings. Ca(2+) signals, elicited in the stellate cells by the action of bradykinin, may have a negative effect on the outcome of the
acute disease
process and promote the development of chronic pancreatitis. The bradykinin-elicited Ca(2+) signals can be inhibited by blockade of type 2 receptors and also by blockade of Ca(2+)-release activated Ca(2+) channels. The potential benefits of such pharmacological inhibition for the treatment of
pancreatitis
are reviewed.
