Role of surgery in the treatment of severe acute necrotic pancreatitis

Between May 1975 and December 1991, a total of 208 patients were operated upon for severe acute necrotic pancreatitis. The decision whether to operate on patients with clinical and biologic aggravation despite particularly sustained intensive care was taken after evaluation of ultrasound and CT scan images. Combining pancreatic body resections and necrotic tissue excision with laparostomy and staged lavage drainage reduced global mortality rate from 49.2 to 16.4 p. cent. The criteria used for determining the indication for surgical intervention, and the technical and tactical operative procedures applied allowing this improvement, are described and discussed.     

Surgical treatment for severe acute pancreatitis: factors which affect the surgical results

Surgical treatment for severe acute pancreatitis has not yet yielded satisfactory results. Several factors which might affect the surgical results of severe acute pancreatitis were analyzed in this study. The presence or absence of infection was not important as a factor determining the surgical results. The severity scores and some biochemical parameters such as CRP, IL-6, PMN-E, HGF seemed to be closely related to surgical results. It was likely that a significant decrease in lymphocyte counts in the blood on admission was closely related to the prognosis of the surgical patients. Timing and procedures for surgery should be more seriously considered in the treatment for patients with such poor general conditions.     

Controlled clinical trial of pefloxacin versus imipenem in severe acute pancreatitis

BACKGROUND & AIMS: Antibiotic prophylaxis in severe pancreatitis has recently yielded promising clinical results, with imipenem significantly reducing the incidence of infected necrosis compared with an untreated control group. On the bases of pefloxacin's spectrum of action and pancreatic penetration, we investigated whether such drugs represent a valid alternative to imipenem. METHODS: In a multicenter study, 60 patients with severe acute pancreatitis with necrosis affecting at least 50% of the pancreas were randomly allocated to receive intravenous treatment for 2 weeks with pefloxacin, 400 mg twice daily (30 patients), or imipenem, 500 mg three times daily (30 patients), within 120 hours of onset of symptoms. Age, sex, body weight, Ranson and Apache II scores, C-reactive protein, etiology, and time from onset of symptoms to treatment were well matched in the two groups. RESULTS: The incidences of infected necrosis and extrapancreatic infections were 34% and 44%, respectively, in the pefloxacin group and 10% and 20% in the imipenem group. Imipenem proved significantly more effective in prevention of pancreatic infections (P 相似文献   

Chylous ascites associated with acute pancreatitis in a patient undergoing continuous ambulatory peritoneal dialysis

We report on a case of chylous ascites associated with acute pancreatitis secondary to gallbladder stone disease, in a patient undergoing continuous ambulatory peritoneal dialysis. The initial clinical presentation was one of bacterial peritonitis, with later appearance of chylous peritoneal drainage. Diagnosis was suggested by abdominal computed tomography and confirmed by surgical exploration. We discuss the main diagnostic keys of peritoneal dialysis-associated pancreatitis and the possible etiologic role of this entity in chylous ascites of these patients.     

Obesity: a risk factor for severe acute biliary and alcoholic pancreatitis

OBJECTIVE: In this study we evaluate the association between obesity and complication development in patients with a first-attack acute pancreatitis (AP), and investigate the influence of comorbid factors on this association. METHODS: Medical records of 150 patients with AP were reviewed. General data, AP etiology, admission AP prognostic criteria, and occurrence of complications were recorded. Patients were classified according to body mass index (BMI) as obese (BMI > 25 kg/m2) and nonobese (BMI < or = 25 kg/m2). RESULTS: Prevalence of obesity was 57%. Thirty-eight percent of the obese patients developed complications as compared with 21% of the nonobese (RR=1.74; 95% CI, 1-2.9). The risk for severe AP increased according to the degree of obesity. Pancreatic and peripancreatic necrosis was more common in obese patients (17.6% vs 6%), as was the incidence of infectious complications. The risk for severe AP was highest in obese patients with either alcoholic (RR=5.3; 95% CI, 1.2-23) or biliary etiology (RR=5.2, 95% CI, 1-26). CONCLUSION: Obesity may predispose to a complicated course of AP, especially if it is secondary to alcohol or gallstones. Further studies are needed to establish the precise prognostic value of obesity in AP, as well as the pathogenic mechanisms involved in the process.     

Chronic pancreatitis, acute pancreatitis

MRCP has been recognized as a safe and noninvasive diagnostic method. In the present study we evaluated the usefulness of MRCP in diagnosis of chronic and acute pancreatitis. Two-dimensional fast asymmetric spin-echo (FASE) MRCP was performed in 40 patients with chronic pancreatitis and 13 with acute pancreatitis. In 29 patients (72.5%) with chronic pancreatitis and 9 (66.7%) with acute pancreatitis, main pancreatic duct (MPD) was visualized entirely. MRCP could demonstrate the characteristic findings of chronic pancreatitis such as dilatation and irregularity of MPD in most cases. In acute pancreatitis, MRCP indicated that MPD was normal in diameter, but irregular in configuration compared with that of the control group. MRCP may facilitate the diagnosis of chronic and acute pancreatitis.     

Eosinophilic gastroenteritis presenting with acute pancreatitis

We present the findings on a 27-year-old male with eosinophilic gastro-enterocolitis accompanied with acute pancreatitis. Acute pancreatitis may be induced by pancreatic duct obstruction caused by marked swelling of the papillary region of the duodenum due to eosinophil infiltration. After prednisolone treatment, clinical manifestations rapidly improved; the serum amylase decreased and the peripheral eosinophilia was recovered. The serum interleukin-5 (IL-5) level was high at diagnosis and decreased by prednisolone therapy; however, IL-5 was detected by enzyme immunoassay even during clinical remission. These results indicate that eosinophilia is mediated by IL-5, and detectable levels of IL-5 indicate the possibility of relapse.     

Duodenal web presenting with acute pancreatitis

An 8-year-old boy presented with acute pancreatitis and was found to have a fenestrated duodenal web (windsock) and associated anomalies. After partial excision of the web and duodenoplasty, he has remained well with no further symptoms.     

The usefulness of the timeliness of endoscopic sphincterotomy in severe acute pancreatitis of biliary origin

There are evidence indicating that endoscopic retrograde cholangiopancreatography with sphincterotomy (ERCP+S) reduces the rate of complications in patients with severe acute biliary pancreatitis (ABP). The aim of this study was to analyze our experience in the treatment of severe ABP with ERCP+S and compare the evolution of the patients treated early (3 days or less following admission) with those treated late (after the 3rd day). A retrospective review of the clinical histories of the 16 patients with severe ABP treated with ERCP+S over the last two years is presented, analyzing their clinical features on admission and evolution. Biliary stones or biliary sludge was observed in 11 cases (69%). Nine patients had undergone early, and 7 late, ERCP+S. The patients of the latter group presented a greater number of complications during evolution than the former group (43% vs 0%; p = 0.025). The mortality of the patients of the late ERCP+S was also greater although without statistical significance (28.6% vs 0%; p = 0.15). No complication secondary to ERCP+S was detected. These findings confirm the fact that ERCP+S performed early in severe ABP significantly reduces the number of complications and is associated with a lower mortality.     

A rare case of severe acute pancreatitis complicated with pancreatic pseudocysts, obstructive jaundice and intraperitoneal hemorrhage

A 58-year-old man visited our hospital because of back pain. Blood examinations revealed the presence of acute inflammation and an increase of pancreatic enzymes. Abdominal computed tomography indicated pseudocysts in the pancreas. The patient was diagnosed as having acute pancreatitis with pseudocysts formation. During the course of the disease, a newly formed pseudocyst in the pancreatic head compressed the common bile duct, leading to the obstructive jaundice. In addition, the rupture of a pseudocyst in the pancreatic tail caused intraperitoneal hemorrhage. This is an interesting case of acute pancreatitis with pseudocysts in which two rare complications developed.     

Ethics and rehabilitation of the patient with severe burns

In the case we present, a physician's order for the treatment of a patient with severe burns unfolds into an ethical dilemma for an occupational therapist. Several conflicting thoughts-in terms of the appropriateness and plan for treatment, while trying to maintain the patient's best interest as the central focus-come to mind. We examine the therapist's ethical responsibilities in light of considerations of futility, nonmaleficence, financial costs, and team relations. Several options for responding to the case are suggested.     

Bleeding intrahepatic cyst in a patient with chronic pancreatitis

This case report describes a patient with bilateral nephrocutaneous fistulae and xanthogranulomatous pyelonephritis. Contralateral involvement of the psoas muscle is a rare occurrence and has not been previously documented.     

Acute renal failure in patients with acute pancreatitis

We describe five patients with acute pancreatitis in whom acute renal failure developed in the absence of hypotension. Pancreatitis was diagnosed clinically, with mean serum and urinary amylase levels of 766 +/- 197 (SE) and 2,378 +/- 572 units/100 ml, respectively. Acute renal failure developed within 24 hours after admission in all patients. It was manifested by oliguria, elevated levels of serum creatinine (mean, 6.9 +/- 1.1 mg/100 ml) and BUN (105 +/-28 mg/100 ml); a urinary sodium level of 72.0 +/- 6.6 mEq/liter; and isosmotic urine (355 +/- 31 mOsm/liter). The mean uric acid level was 18.6 +/- 1.6 mg/100 ml. Blood pressure was recorded frequently, and the lowest mean diastolic pressure was 96 +/- 6 mm Hg. The duration of the oliguric phase of acute renal failure was 8.2 +/- 1.7 days, and all patients recovered from both the acute pancreatitis and acute renal failure. In summary, acute pancreatitis, per se, can precipitate acute renal failure. It occurs early in the course of the pancreatitis, and extreme hyperuricemia is frequent finding that does not adversely affect the recovery of renal function.     

Therapy of acute pancreatitis

The mortality rate in acute pancreatitis (AP) is significantly lower in patients hospitalized directly at the intensive care unit than in patients admitted to hospital in 2 weeks after the assessment of diagnosis, prophylactic administration of low-molecular protease inhibitor reduces the occurrence of post ERCP pancreatitis a well a coincident complications. Despite rational considerations concerning the significance of pryphylactic administration of antibodies (ATB) in severe AP, there still not enough convincing data which could be recommended a standard therapy. One of the concepts of causal therapy of AP. Suggest that inhibition of exocrine pancreatic enzymatic secretion reduces autodigestion of the gland (setting the gland at rest). The reports on success of secretin-inhibiting substances a glucagon, calcitonin, atropine and somatostatin require confirmation in randomized or accurately defined comparable groups. The initial studies on the therapeutic significance of lexipanphate-antagonist of platelet activating factor (PAF) in acute pancreatitis is promising. A long-term lavage had reduced the mortality.     

Therapy of acute pancreatitis

Therapy in patients with acute pancreatitis (AP) is primarily conservative and follows the rules of generally accepted principles. A very important basis in the treatment of AP is the interdisciplinary approach to this disease which demands teamwork between clinicians, intensive care specialists and surgeons. Patients with a necrotising course should be hospitalised on the ICU and should receive maximum intensive care measures and antibiotics. Indications for surgical interventions in severe AP are infected pancreatic necrosis and non-response to intensive care therapy.     

Identifying the patient with sleep apnea: upper airway assessment and physical examination

Since the final common pathway for obstructive sleep apnea is obstruction of the upper airway during nocturnal respiration, examination and assessment of the anatomy of the upper airway plays a central role in patient evaluation. Since the upper airway begins at the nose and lips and ends at the larynx, a complete assessment of the upper airway evaluates this entire length of this anatomic region including the bony framework and soft tissue. Though office assessment of these structures does not necessarily mimic the appearance of behavior of these structures during physiologic sleep, the office examination can give important information as to the site of obstruction during sleep that can help direct therapy.
