Radical resection of periampullary tumors in the elderly: evaluation of long-term results.

Increasingly, patients of advanced age are coming for evaluation of periampullary tumors. Although several studies have demonstrated the safety of resecting periampullary tumors in older patients, few long-term survival data have been reported. Between 1983 and 1992 various periampullary masses were resected in 70 patients over age 65 (range 65-87 years). Total pancreatectomy was performed in 11 patients, and 59 patients underwent pancreaticoduodenectomy. The mean duration of hospitalization was 17 +/- 15 days. Major complications occurred in 27 patients (39%), and operative mortality rate was 8.5%. Overall median survival was 24 months; and 5-year survival was 25%. Perioperative outcome was compared in patients aged 65 to 74 years and in patients > or =75 years old. The older age group required longer periods in the surgical intensive care unit postoperatively, but the long-term survival was similar in the two age groups. Radical resection with the intent to cure periampullary tumors is safe in selected patients of advanced age, and long-term survival is in the range of expected survival for younger patients with the same tumors.

A subcutaneous or subfascial jejunostomy is beneficial in the surgical management of extrahepatic bile duct cancers.

BACKGROUND: Extrahepatic bile duct cancers are rare tumors with a dismal prognosis. Even after a resection, obstructive cholestasis and other biliary complications are the rule. To facilitate retrograde access to the biliary tree for treatment of such biliary complications, a modified Roux-en-Y hepaticojejunostomy is constructed such that the afferent limb is brought up as a subcutaneous or subfascial jejunostomy (SJ). The safety and utility of construction of an SJ was evaluated in patients with extrahepatic cholangiocarcinoma. METHODS: From 1985 to 1997, 24 patients with extrahepatic bile duct cancers received an SJ as part of their management. Demographic data, operative data, tumor characteristics, and postoperative courses were retrospectively reviewed. All but 3 patients were followed to the time of death. RESULTS: The average age of the patients was 62 +/- 9 years. The tumor was resected in 17 patients. Major complications occurred in 5 patients (21%). There was 1 operative death (4%). None of the complications could be attributed to construction of the SJ, although 1 patient had a soft tissue infection at the site of the percutaneous access of the SJ. Frequent dilatations of biliary strictures were required in 5 patients, and 1 patient eventually required insertion of an internal biliary stent. These procedures could all be accomplished through the SJ. CONCLUSIONS: The SJ is a technically simple and safe addition to the management of resectable and unresectable extrahepatic bile duct cancers, particularly proximal lesions. The procedure facilitates brachytherapy if indicated, and it allows convenient management of postoperative biliary complications, including recurrent strictures.

A phase I study of chemoembolization with cisplatin, thiotepa, and lipiodol for primary and metastatic liver cancer.

Thirty patients with primary hepatocellular carcinoma or liver metastases were entered into a program of chemoembolization with cisplatin, lipiodol, and escalating doses of thiotepa. Doses of cisplatin were 100/m2, and thiotepa doses ranged from 9 mg/m2 to 24 mg/m2. Two of three patients with ocular melanoma had partial responses in the liver metastases for 3+ and 16 months. In patients with either hepatocellular carcinoma (15 patients) or primary cholangiocarcinoma of the liver (three patients), there were two partial responses, for 22 and 33 months. Five patients had minor responses: four with a 40% reduction in tumor and one with a mixed response. There were four early deaths, which involved sepsis in two patients, respiratory failure in one, and acute myocardial infarction in one. Otherwise, toxicity was tolerable and reversible and included abdominal pain and transient elevation of serum creatinine, bilirubin, and transaminases. Less common toxicities included ototoxicity and peripheral neuropathy. Chemoembolization of the liver with cisplatin, thiotepa, and lipiodol can produce responses, but toxicity can be significant. The recommended starting phase II dose for future studies is thiotepa 24 mg/m2 and cisplatin 100 mg/m2.

Percutaneous dilatation of biliary strictures through the afferent limb of a modified Roux-en-Y choledochojejunostomy or hepaticojejunostomy.

BACKGROUND: This report is a 13-year prospective evaluation of percutaneous balloon dilatation of benign biliary strictures through the subcutaneous or subfascially positioned afferent limb of a choledocho or hepaticojejunostomy in 30 patients. DATA SOURCE: Twenty-seven strictures developed after a common duct injury sustained at the time of cholecystectomy, two after hepatectomy reconstruction for trauma and one following a gastrectomy. Twelve injuries (40%) were recognized at operation. Of the 18 patients where the injury was unrecognized at the time of operation, 8 had not been reoperated at the time of referral, 7 had late repairs by the referring physician, and 3 had late repairs at our institution. The follow-up is 1 to 13 years. RESULTS: There has been 1 late death and 6 patients are lost alive. The jejunal-limb was accessed 50 times with two minor and no major complications. There have been two parajejunal hernia repairs, but there have not been any reoperations for recurrent biliary strictures. CONCLUSIONS: Benign biliary strictures can be effectively managed by repeat balloon dilatations thru the afferent limb of a choledocho or hepaticojejunostomy, thus eliminating the need for repeat surgical interventions.

Laparoscopic cholecystectomy in cirrhotic patients.

BACKGROUND: Reported mortality for open cholecystectomy in patients with cirrhosis ranges from 10% to 80%. Laparoscopic cholecystectomy has gained acceptance in the general population and has become the procedure of choice for symptomatic cholelithiasis. We reviewed our experience with the use of laparoscopic cholecystectomy in this group. STUDY DESIGN: We did a retrospective review of the records of 25 consecutive laparoscopic choleoystectomy procedures performed on cirrhotic patients from May 1992 to July 1996. RESULTS: There were no mortalities in our group. All procedures were completed laparoscopically. Mean length of stay was 1.7 days (range, 1 to 8 days). Morbidity consisted of wound hematomas, pneumonia, and ascites for a rate of 32%. Only patients with Child's Class A and Class B cirrhosis were operated on. CONCLUSIONS: Laparoscopic cholecystectomy can be performed safely in cirrhotic patients with well compensated liver function.

Ciliated foregut cyst of the pancreas.

Cystic lesions of the pancreas are relatively uncommon. We describe the case of a young man with a complex cystic mass located within the head of the pancreas. The patient underwent exploration with resection of the mass. Pathology revealed a ciliated epithelial cyst, a rare cystic lesion of the pancreas.

Balloon dilatation through the subcutaneously placed afferent limb of a hepaticojejunostomy in patients with resected Klatskin tumors.

It is generally conceded that palliation for proximal bile duct tumors (Klatskin) is exceptional if obstruction and the resultant infections can be prevented. Our experience with balloon dilatations thru the subcutaneously placed afferent limb of a choledocho or hepatico jejunostomy in patients with benign strictures suggests that this approach will be effective in patients with malignancies and thus provide long-term control of the obstruction without the need for external tubes. This is a report on one patient who, following a resected Klatskin tumor with positive margins, was treated with transhepatic internal external stents and was converted to a subcutaneous limb following numerous bouts of cholangitis. A schedule for repeat dilatations thru the jejunal limb was established. The patient has remained afebrile with a normal bilirubin and a moderately elevated alkaline phosphatase. Recurrent tumors or postirradiation strictures in patients with resected Klatskin tumors can be effectively controlled by repeated balloon dilatation without the need for external stents.

A phase II trial of recombinant leukocyte interferon plus doxorubicin in patients with hepatocellular carcinoma.

A Phase II trial of combination therapy with recombinant leukocyte interferon (alpha IFN) and doxorubicin was performed in patients with unresectable hepatocellular carcinoma. alpha IFN was administered at a starting dose of 20 x 10(6) U/m2 intramuscularly or subcutaneously with doxorubicin 20 mg/m2 intravenously weekly x 3 weeks followed by a 2-week period rest. There were 22 patients entered into the study. Among the 21 patients, there were 2 partial responses (10%), one minor response, and one patient had stable disease. Toxicity was generally tolerable, with fever, fatigue, and myelosuppression being the most common side effects. This combination of weekly recombinant leukocytic interferon and doxorubicin has modest and limited activity in hepatocellular carcinoma.

A phase I study of chemoembolization with cisplatin and lipiodol for primary and metastatic liver cancer.

Twenty patients with either unresectable primary hepatocellular carcinoma or hepatic metastases were entered into a chemoembolization program with cisplatin and lipiodol; 19 patients were evaluable for response. Doses of cisplatin ranged from 40 to 100 mg/m2. Toxicity was tolerable and reversible and included abdominal pain, transient elevation in serum creatinine, serum bilirubin, and serum transaminases. Less common side effects include fever, ascites or pleural effusion, and hiccups. Two of four patients with ocular melanoma had partial responses. Duration of response was 10 and 11 months. Among 8 patients with unresectable hepatoma, 2 patients had partial response for 10+ and 13 months, 2 had minor response for 2 months and 4+ months, 1 patient had stable disease for 5+ months, and 3 patients failed to respond. Of the six colon cancer patients treated, one had a partial response in the liver, but developed progressive nodal disease, and another patient had a partial response for 3 months. Chemoembolization of the liver with cisplatin and lipiodol is feasible and doses of cisplatin at least 100 mg/m2 are tolerable. Antitumor activity in metastatic ocular melanoma is encouraging but requires further study.

Giant colonic diverticulum: an unusual manifestation of a common disease.

Giant colonic diverticula are an uncommon manifestation of colonic diverticular disease. This report documents another case of this rare entity. The clinical presentation is variable, but abdominal pain and the presence of an abdominal mass are common. Their etiology is uncertain, but they are thought to originate from pulsion diverticula. Abdominal plain films and barium enema are helpful in making the diagnosis. Computerized tomography is useful when the diagnosis is unclear. Surgical resection is recommended to alleviate symptoms and avoid complications.

Laparoscopic ligation of a leaking cystic duct.

Laparoscopic cholecystectomy (LC) has rapidly become an acceptable surgical technique. Indeed it may become the preferred method for cholecystectomy, with the open method reserved for complicated cases. Early series of LC have shown a mortality rate of 0-1%, comparing favorably to the open method. However, complications such as bile duct injury, cystic duct leaks, and biliary collections may be more frequent. We report the first case of cystic duct leakage after LC successfully managed by subsequent laparoscopic ligation.

Portal hypertension. A fifteen year perspective.

Two hundred six consecutive patients were followed from 5 to 15 years after a distal splenorenal shunt operation. Nonalcoholic patients demonstrated nearly twice the survival rate when compared with alcoholic patients. The mean duration of life for the surviving nonalcoholics was 10 years and for the alcoholics, 9 years. We predict that approximately a third of the nonalcoholics will enjoy long-term survival. The operative mortality rate was similar in both groups, being about 4 percent. The risk of liver cancer was highest in the male alcoholics, and long-term survival was greater for women in both the alcoholic and nonalcoholic groups.

The unusual presentation of "large" gallstones. The diagnostic role of endoscopy.

Large gallstones are usually seen in old people, but are distinctly uncommon. They may cause complicated gallbladder disease requiring extensive surgery. Unusual presentations of such stones include Mirizzi's syndrome, biliary fistulas, and gastric outlet obstruction (Bouveret's syndrome). Preoperative endoscopy can accurately define these complications to facilitate their surgical management.

Biliary excretion of aztreonam in patients with biliary tract disease.

The biliary excretion of aztreonam was studied in 10 post-cholecystectomy patients with T-tube biliary drainage (group A) and four other subjects with obstructive biliary tract disease who had recent placement of external biliary drainage (group B). Maximum biliary levels ranged from 9.7 to 88.2 micrograms/ml (mean, 42.9 +/- 7.9 micrograms/ml) and occurred 2.4 h after injection of a single 1-g dose intravenously. Peak biliary levels observed in group B patients were approximately one-third those in group A. Cumulative 12-h biliary excretion (group B) accounted for 0.18 +/- 0.06% of the total dose. In the same period, urinary excretion accounted for 65 to 72% of the total dose. The lower biliary levels of aztreonam observed in group B patients relative to those in group A suggest that in patients with total biliary tract obstruction the liver may not recover full secretory capacity, at least within 3 to 7 days after biliary decompression.

Ampicillin versus cefamandole in biliary tract surgery. A prospective, randomized clinical and bacteriological study.

A prospective, randomized study was conducted on 219 surgical patients with biliary tract disease. There were 100 patients undergoing elective biliary surgery, and 119 others with suspected biliary sepsis who were assigned to Prophylactic or Therapeutic clinical categories, then randomized into ampicillin or cefamandole treatment groups. Organisms resistant to the antibiotics given were found less often among patients in the cefamandole groups than among those in the ampicillin groups. No postoperative wound or intra-abdominal sepsis (IAS) occurred in the Prophylactic category. In the Therapeutic category there were two cases (3.2%) of wound and IAS in the ampicillin group and one case (1.8%) of wound infection in the cefamandole group. Overall, cefamandole showed superior coverage in vitro against the biliary flora, but both drugs were equally effective in maintaining a low incidence of postoperative sepsis as well as a minimal number of febrile or total hospital days. The authors suggest that the choice of antimicrobials may not be as critical as effective surgical management in the prevention of septic complications following biliary tract surgery.
