Surgical procedures can be accomplished successfully in patients with uremia provided certain principles of perioperative management are observed. Preoperative dialysis minimizes the biochemical derangements and improves fluid balance, hypertension and hemostasis. Drug schedules are adjusted in consideration of abnormal metabolism in renal disease. Anesthetic management is modified in recognition of potentially adverse or altered activity of anesthetic agents and neuromuscular relaxants. The lightest plane of
anesthesia
consistent with expeditious operative technique is maintained, since adequate tissue oxygenation is dependent upon increased cardiac output in these invariably anemic patients. Intraoperative hyperventilation sustains the usual compensatory mechanism for uremic metabolic acidosis in the conscious patient, thereby averting increments in serum potassium levels associated with increasing acidosis. Postoperative morbidity may include shunt thrombosis, infection, impaired wound healing, bleeding, pericarditis, pleuritis and
pancreatitis
. Hypervolemia and hyperkalemia are best managed by early postoperative dialysis. A period of nutritional support using intravenous essential L-amino acids and hypertonic glucose appears promising, especially when gastrointestinal dysfunction exists.

In modern surgery, the pancrectomy is an operation indicated in a wide number of cases. Indications for such a procedure that were once limited to malignant lesions of the papilla of vater and the head of the pancreas now include chronic pancreatitis, some benign lesions of the duodenopancreatic area, and serious cases of acute necrotizing
pancreatitis
. Thanks to Modern surgical technique especially in
anesthesia
, reanimation, and postoperative care, the mortality rate in the partial pancrectomy is Recured to a rational number. Nonetheless, postoperative exiturs cannot be neglected. As a result it is necessary to consider strict indications for a pancrectomy. Only under such conditions can satisfactory therapeutic results be achieved.

Postoperative hyperamylasemia is found in 6 to 32% of patients undergoing abdominal and extraabdominal surgery. The minority of these patients exhibited the clinical signs of a postoperative
pancreatitis
. Isoamylase analysis revealed that the rise was in the pancreatic-type isoamylases or in the salivary-type isoamylases. We found an elevation of serum amylase following surgery of the parotid gland in 18 out of 20 patients, but the amylase levels were still below the normal upper limit. In 12 cases the increase of amylase activity was due to an increase of the salivary and pancreatic components of the serum amylase. 6 patients showed an increase of the pancreatic component only. The causes of the non-specific hyperamylasemia could lie in the operation itself, in the intubation and in pharmacons used during
anaesthesia
.

Diagnostic re-evaluation of measurement of electric skin resistance (ESR), skin temperature (ST) and deeper tenderness (DT) was performed in patients with abdominal pain due to
pancreatitis
, cholecystopathy and duodenal ulcer. These determinations were conducted when the pain was complained of and after the pain ceased by paravertebral
anesthesia
. ESR was decreased on the opposite tender points of the abdominal walls as compared with those values of the healthy abdominal walls. On the contrary, ESR was increased on the suffered body areas in patients with active myelitis. ESR was decreased on the abdominal walls where visceral pain was induced by inflation of a balloon attached to the apex of a Miller-Abbott double lumen tube. DT tended to show decrease, while ST a slight increase, when the pain was evoked. However, in these pain induced experiments, ST changes were not so remarkable as those of ESR. A viscero-cutaneous reflex machanism and the predominance of sympathetic nerve control might be possible causes to produce these changes. Several important factors influencing the determination of the ESR were also discussed.

Twenty-four dogs were divided into five groups. Under pentothal sodium
anesthesia
, those in the control group received no further manipulation; another group underwent laparotomy only; and dogs in the last three groups had induced
pancreatitis
, intestinal ischemia and duodenal perforation, respectively. An analysis was made of serum and peritoneal lavage fluid in the dog of each group at 30 minute intervals for four and one-half hours. Parameters which were significantly elevated in dogs with
pancreatitis
compared with other groups included fluid amylase, lactate dehydrogenase, proteolytic activity and intestinal alkaline phosphatase and serum amylase. We judge that these biochemical differences in the lavage fluid, when taken with the physical characteristics of the fluid and the clinical symptoms, can significantly aid the clinician in arriving at the diagnosis of acute pancreatitis.

Extracorporeal shock wave lithotripsy of gallstones is a safe and well-tolerated procedure. Patients are now treated without general
anesthesia
and, increasingly, on an outpatient basis. Skin petechiae and transient hematuria are the most common side effects. Episodes of biliary colic are common in the follow-up period, but more serious adverse side effects such as cholecystitis and
pancreatitis
are distinctly uncommon. It is estimated that only 15% to 20% of all patients with symptomatic cholelithiasis are suitable lithotripsy candidates. As our knowledge of the procedure grows, it seems clear that the best results are obtained in patients with solitary radiolucent stones less than or equal to 20 mm, with stone-free rates at 12 months above 80%, for this selected group of patients. Adjuvant oral bile-acid dissolution therapy should be used in conjunction with gallstone lithotripsy. Gallstone recurrence remains to be established by clinical studies. Therapy for gallstones in 1991 has to be reevaluated by an interdisciplinary approach, taking into account not only open cholecystectomy, but also other modalities such as medical dissolution, laparoscopic surgery, percutaneous cholecystolithotomy and extra-corporeal shock wave lithotripsy. The appeal of the laparoscopic approach will substantially reduce the pool of patients for lithotripsy. Nevertheless, lithotripsy will continue to be a viable treatment option for patients with a single radiolucent stone. It is an outpatient procedure and doesn't require any incision or general
anesthesia
.

Severe necrotizing
pancreatitis
is accompanied by release of hemorrhagic ascites fluid (HAF), which is thought to be related to the occurrence and frequency of cardiocirculatory and pulmonary failure as a consequence of acute pancreatitis. The purpose of this study was to evaluate the role of HAF due to these systemic complications. Experiments were performed in 25 pigs (mean b.wt. 22 +/- 1 kg) under general
anesthesia
and mechanical ventilation. The animals received 50 ml/kg b.wt. i.p. of either physiologic saline solution (control CO, n = 9) or hemorrhagic ascites fluid (HAF, n = 16). HAF was obtained from 16 pigs with
pancreatitis
induced by intraductal infusion of bile salt. Eight animals in the HAF group were pretreated with indomethacin (10 mg/kg i.v. INDO/HAF). All animals were followed up for 6 h. Mean arterial pressure, cardiac output, and stroke volume fell significantly in the HAF (-25%, -27%, -27%) and in the INDO/HAF groups (-24%, -20%, -17%) as compared with controls (-6%, -6%, -6%). Also, left ventricular end-diastolic pressure (LVEDP) decreased by 52% and 48% in both HAF recipient groups, whereas LVEDP was unchanged in the control group. Myocardial contractility (Vmax) remained unaltered in all experimental groups. No significant differences in gas exchange and lung dry/wet weight ratio were observed. Lipase and PGI2 of the unpretreated HAF group rised to 203% and 198% in arterial blood at 6 h compared with unaltered levels in the control group. No increase of prostanoid concentrations was detected in the indomethacin-pretreated group, whereas lipase increase by a comparable extent as in the HAF group. We conclude that the early consequences of HAF are mainly characterized by systemic hypotension due to hypovolemia.

Despite intense interest in laparoscopic cholecystectomy, biliary lithotripsy (BL), by avoiding the need for general
anesthesia
, could remain a useful alternative in approximately 10% of patients with symptomatic gallstones. The poor stone clearance rates reported by the Dornier National Biliary Lithotripsy Study has led to disenchantment with biliary lithotripsy. However, the results may reflect the relatively low kV (18.7 +/- 1.7) used. We have compared symptomatic gallbladder stone/cholecystolithiasis patients with one to five stones of aggregate diameter < 60 mm treated with one to three sessions on an MPLS 9000 (Dornier) lithotripter at moderate kV (22.7 +/- 1.7 kV; mean number of shocks 1473 +/- 356) with a similar group treated with high kV (26 kV, mean number of shocks 1357 +/- 507). Ultrasound stone diameter measurements were made pre- and post-BL; 12-wk results are reported. Treatment safety was assessed by recording adverse experiences and serum, urine, hematology, and chemistry. For patients with single stones, the high kV treatment took significantly (p < 0.05) less time (74 +/- 30 min) than moderate kV treatment (118 +/- 33 min). At 3 months, the moderate kV-treated single-stone group had a residual maximum fragment size of 3.2 +/- 3.3 mm versus 1.8 +/- 2.3 mm in the high kV-treated single-stone group. The 3-month stone-free rate for patients with single stones treated at high kV was 44% compared with 46% for the moderate kV-treated group (NS). At 1 wk, 11 patients had microscopic or macroscopic hematuria and six patients had mildly elevated liver function tests. At 6 wk, however, all urine and hematological measurements had returned to normal. Two patients suffered
pancreatitis
, one in each group. High kV BL appears to be safe and, for patients with single stones, gives better fragmentation and takes less time to administer than moderate kV. Whether a high kV treatment protocol can achieve improved long-term stone-free rates remains to be assessed.

Records of 940 patients with endoscopic sphincterotomy (ES) and 100 patients with choledochotomy for stone removal were compared. Those with ES were characterized by older mean age (65.9 vs. 60.6, p < 0.001), similar frequency of operative risks (36% vs. 45%), and a less complication rate (8.2% vs. 53%, p < 0.001) as compared with the surgery group. Complications of ES included cholangitis,
pancreatitis
, bleeding, and basket impaction. One patient each with cholangitis and
pancreatitis
died, thus a mortality rate of 0.2%. Complications of choledochotomy occurred in 53 patients with no death. Most of them were associated with
anesthesia
, laparotomy, wound and immobilization. The complications of ES should decrease due to recent development of lithotripsy instruments and endoscopic stenting to prevent cholangitis. Follow-up of 74 patients 15-21 years after surgical sphincterotomy revealed recurrent stones in 3.5%, which was lower than a recurrence rate of 10.3% in 290 patients 5-14 years after ES. However, that rate may be an underestimate, because the follow-up was obtained in only 79% of those with surgical sphincterotomy as compared with 99% of ES. Ninety percent of those with recurrence after ES underwent endoscopic treatments again, whereas 10% had surgery. Easy repetition at the time of recurrence is one of major advantages of the endoscopic treatment.

The safety and efficacy of piezoelectric extracorporeal shockwave lithotripsy in the treatment of symptomatic gallbladder stones were evaluated in 53 consecutively treated patients. All treatments were performed as outpatients without
anesthesia
; over 95 per cent of 109 treatments were performed without analgesia or sedation. Ursodeoxycholic acid was administered post-treatment. Seventy per cent of patients had multiple sessions. Cumulative stone-free rates of 38 per cent at 6 months, 65 per cent at 12 months, and 75 per cent at 15 months were achieved. There was no difference in eventual stone clearance between patients with single stones less than 20 mm diameter, single stones greater than or equal to 20 mm diameter, or multiple (two or three) stones, although patients with single smaller stones required significantly fewer total shocks to become stone-free (P = .02). Stone clearance correlated with estimated stone volume. Biliary pain occurred in 62 per cent of patients after treatment but ceased in stone-free patients. Biliary complications of
pancreatitis
(7.5%) and choledocholithiasis (3.8%) were successfully treated by endoscopic papillotomy. Nonbiliary complications were virtually nonexistent. Three patients (5.7%) had elective cholecystectomy. Results indicate that piezoelectric lithotripsy is a safe, minimally painful treatment that, in conjunction with oral bile acids, can produce stone-free rates of 75 to 100 per cent in selected patients.
