Twenty-nine patients, divided into three groups: 1) chronic obstructive pulmonary disease; 2) acute or chronic pulmonary disease with left heart failure; 3) respiratory insufficiency after peritonitis, pancreatitis, and/or sepsis, were studied during respirator treatment with regard to gas exchange, breathing mechanics and central circulation. The dead space ventilation was somewhat greater in group 1 than in the other groups. The alveolar-arterial oxygen tension difference was least in group 1, greater in group 2 and extremely high in group 3. Neither dynamic compliance of the thorax nor inspiratory resistance showed any significant differences between the groups. The cardiac output had the highest values in group 3. The venous admixture was generally small in group 1 and extremely large in group 3. The pulmonary artery pressures were highest in group 2. Three variables proved to be valuable when assessing the prognosis of a patient: a large venous admixture; a large alveolar-arterial oxygen tension difference, and a high pulmonary artery pressure indicated a less favourable prognosis.

Of 92 patients with moderately severe acute pancreatitis initially studied within three weeks of onset by ultrasonic tomography, 52 developed an acute fluid collection in the lesser sac. Documentation of the ultrasound prediction of pseudocyst was achieved by surgery or autopsy in 26 cases. Spontaneous resolution of the acute pseudocyst was demonstrated by serial ultrasonography and radiogrphy in another 10 patients. Exploration exposed 3 false positive predictions of pseudocyst. Eleven other patients with a cystic configuration either refused surgery or were lost to followup. Acute pseudocyst formation is a relatively common phenomenon in the early phases of moderately severe pancreatitis. While spontaneous resolution of acute pseudocysts is frequent, in approximately 50% of cases acute pseudocysts progress to chronic pseudocysts. A distinction between acute and chronic pseudocyst is necessary since specific surgical management depends upon the phase of pseudocyst development. Unless regional sepsis supervens, acute pseudocyts of less than three weeks' duration may be followed by serial ultrasonography in the hope of spontaneous resolution. When a pseudocyst has achieved chronic status, spontaneous resolution is rare. Persistent conservative management under these conditions invites the excessive mortality and morbidity of spontaneous rupture.

In a group of 260 non-selected cases of acute or subacute pancreatitis, severe complications occurred in 60 (23.1%). Long lasting shock and/or massive internal bleeding (5.4%), severe renal problems (anuria, tubular necrosis, nephrosis) (5.4%) and frank hepatic failure due to extensive liver necrosis or other severe destruction (5.0%), invariably lead to death. The clinical group of findings pointing to a fatal course usually manifested themselves during the first three days. Severe renal and hepatic lesions were in many cases secondary to shock in fulminant rapidly deteriorating cases. Preventing and efficient management of shock are thus essential prerequisites for saving the patient. Other important complications included severe intra-abdominal suppuration and abscesses, peritonitis and sepsis (3.9%), pseudocysts of the pancreas (5.4%) and biliary statis (18.4%). Severe obstruction to bile flow with associated jaundice occurred in only 4.6% of cases; unselected operative biliary decompression does not therefore appear indicated. If an early laparotomy is performed, efficient debridement and drainage are of utmost importance. Fatal panreatitis was associated with extensive necrosis of the pancreas in about 80% of cases; possibly subtotal pancreatic resection at an early laparotomy would have given better results in these most severe cases, as recently reported in the literature.

Intestinal fistulization following acute pancreatitis is a complication of abscess formation and may occur after initial surgical drainage. It should be suspected in anyone with protracted pancreatitis in whom an abdominal mass suddenly disappears or in whom gastrointestinal bleeding develops. Although transient improvement may occur, decompression will often be incomplete and will usually be followed by recurrent sepsis or severe life threatening hemorrhage. For this reason, spontaneous fistulization into the intestine does not eliminate the need for adequate surgical drainage. With fistulas into the colon, drainage should be combined with proximal diverting colostomy. Some duodenal fistulas may respond to abscess drainage and intravenously administered hyperalimentation, while others may require drainage plus conversion from a side to an end fistula.

Pancreatic abscess is probably the most serious complication of acute pancreatitis. During the ten-year period from 1966 to 1975, twenty-eight patients with pancreatic abscess following acute pancreatitis were treated by surgical drainage. A review of these cases revealed that there was a lull in the clinical course of the antecedent pancreatitis prior to the time of surgical drainage in 70% of the cases. Despite an aggressive surgical approach, there were major postoperative problems in 26 patients. Sepsis persisted in 14 patients. Major gastrointestinal hemorrhage occurred in seven, intra-abdominal bleeding in nine, and fistulization in 13. Fourteen patients died (a mortality of 50%). The operative treatment of pancreatic abscess must be aggressive and persistent. In addition to extensive drainage with soft sump drains, vigilance must be exercised to avoid pressure against bowel or major vessels. Reoperation should be considered if postoperative improvement is not sustained.

A retrospective analysis of complications arising from 300 consecutive attempts at endoscopic retrograde cholangiopancreatography (ERCP) in 278 patients was undetaken to determine the rate and severity of complications. An over-all complication rate of 5% (15 cases) was documented. Complications were categorized in terms of those arising from endoscopy itself or from the administration of pharmacological agents (7 cases), and those observed after the injection of radioopaque contrast into the biliary tree or pancreas (8 cases). Complications which might be considered coincidental to a patient's underlying illness were not excluded. Complications were significantly more frequent after injection of diseased duct systems. Brief, self-limited pancreatitis after retrograde pancreatography occurred in 5 of 90 patients with pancreatic disease. No cases of pancreatitis were observed after retrograde pancreatography in 102 patients without pancreatic disease X2 = 5.82, P less than 0.025). Sepsis occurred after retrograde cholangiography in 3 of 56 patients with extrahepatic biliary obstruction. In the absence of extrahepatic obstruction, cholangiography was performed without complication in 85 cases (X2 = 3.62, P less than 0.1), although 25 of these had intense cholestasis due to hepatic parenchymal disease. This analysis provides the basis for modifications of ERCP technique and management that may reduce the future incidence of complications. This study suggests that the incidence and severity of complications that arise from ERCP compare favorably with procedures of equivalent diagnostic yield.

During the period of 1962 to 1972, 71 patients underwent surgical treatment of pancreatic pseudocysts. Internal drainage was performed in 73% of these patients in comparison to only 20% in a series during the previous decade. From an analysis of results, it would appear that the treatment of choice is internal drainage via either cystogastrostomy or cystojejunostomy. Postoperative bleeding and sepsis were of negligible consequence. An unexpected finding was that the long-term results of these patients seemed to be better than those of patients with pancreatitis in whom pseudocysts did not develop.

Of 402 United States owners of side-viewing duodenoscopes surveyed, 222 (55%) responded, reporting 10,435 endoscopic retrograde cholangiopancreatograms. Procedure failed occurred in 30%, complications in 3%, and death in 0.2%. Complications included pancreatitis, cholangitis, pancreatic sepsis, instrumental injury to the gastrointestinal tract, and drug reactions. Pancreatitis was associated with injection into the pancreatic duct, sepsis with injection into an obstructed duct or pseudocyst, and injury with abnormal gastroduodenal anatomy. Experienced workers had a 15% incidence of complications, whereas inexperience gave 4 times the failures (62%) and twice the complications (7%). The causes of complications and their prevention are discussed.

Fourty-nine patients (21 female, 28 male) with ulcerative colitis underwent formation of an J-ileal pouch and construction of a direct stapled pouch-anal anastomosis (IPAA) without rectal cuff. 16 patients had previously undergone surgical interventions. Overall after IPAA 7 patients (14%) experienced 11 major complications. Gastrointestinal complications included hemorrhage in 1 patient, pelvic sepsis and ileus in 3 patients, respectively. Pancreatitis and urinary infection occurred in 2 patients, sexual dysfunction in 3 patients. After closure of the ileostomy 3 patients developed late pouch-vaginal or pouch-vesical fistulas, leading to excision of the pouch. During the long-term follow-up small bowel obstruction developed in 3 patients, pouchitis in another 6 patients. After 3 months 84% of our patients were continent during daytime, 67% during nighttime. 24 months postoperatively these data concerning continence increased to 92% and 83%, respectively. We conclude that direct IPAA is a reliable procedure achieving its purpose in 96%.
