Introduction Pancreatic cancer is a leading cause of death in North America and Western Europe with rising rates in the developing world. Endoscopic ultrasound (EUS) with FNA (fine needle aspiration) is a critical component in the evaluation and diagnosis of pancreatic lesions with a high sensitivity and specificity. In this paper, we report patients at our center who eventually developed pancreatic cancer despite an early negative EUS, and identifying factors that may result in a missed diagnosis.Methods The University of Louisville database was queried for patients who had a Whipple procedure for presumed benign disease and had a pre-operative EUS between 2008 and 2018. Patients who had pancreatic adenocarcinoma on final pathology were identified. Demographic, clinical, EUS, operative, and pathologic details were reviewed for each case in efforts to identify factors associated with failure to diagnose a pancreatic malignancy on EUS.Results Five patients who had pancreatic adenocarcinoma on final pathology were reviewed in detail and their cases are presented in the paper. Four of the patients had dilation of the common bile duct, three had chronic pancreatitis. Two of them had previous surgery on the pancreas or bile ducts.Conclusions All of the patients presented in the paper had variables that made their EUS evaluation challenging. A high index of suspicion must be maintained in patients that do not improve after appropriate treatment of their strictures or pancreatic lesions. In the future, new techniques, such as fine needle biopsy and biomarker assays, may improve diagnosis accuracy.

BACKGROUND: It is now possible to manage most extrahepatic bile duct strictures, benign or malignant, using endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic dilatation and stenting. METHODS: Over a 5-year period we treated 218 patients with strictures of extrahepatic bile ducts. Eighty-six patients had benign biliary stricture. Endoscopic treatment was performed in 67 (78%) of these patients. Open surgical biliary drainage was preferred in 12 patients (14%), and 7 patients (8%) were managed conservatively without stenting or surgery. One hundred and thirty-two patients had malignant biliary stricture. One hundred and one patients (77%) underwent endoscopic stent placement. Thirty-one patients (23%) underwent surgery for potential curative resection after diagnostic ERCP. The average life span in the malignant stricture group was 5 months (range 0.1 to 25 months) after the initial endoscopic procedure. RESULTS: Altogether 313 endoscopic procedures in 218 patients were performed for benign and malignant bile duct strictures. Complications included hemorrhage in 8 (3%), pancreatitis in 10 (3%), and suspected retroperitoneal perforation in 2 (0.6%). There were no ERCP related deaths; one patient died of uncontrolled bleeding from transhepatic stenting. In benign strictures, there has been no recurrence of strictures after the last stent removal with a mean followup of 21 months (range 0.1 to 31 months). All complications were successfully treated conservatively. CONCLUSIONS: Endoscopic management of benign and malignant biliary stricture is possible with minimal morbidity and mortality and should be considered an acceptable option to surgical management.

We analyzed the results of laparoscopic cholecystectomy in 1,983 patients from a variety of practice settings in order to evaluate a large, cross-sectional experience for this new procedure. Twenty general surgeons from 9 clinics in 4 states examined the records and outcome of their laparoscopic cholecystectomy patients through March 1991. In 88 patients (4.5%), the operation was converted to an open procedure, usually because of marked inflammation and unclear anatomy. A total of 644 cases were performed with laser dissection and 1,339 with cautery, and the results of these 2 methods were similar. There were 41 complications. Reoperation for repair was necessary in 18 patients, including 5 with common duct injuries, and, to date, the outcome has been good in each patient. Seventy-six patients (3.8%) have had recognized common duct stones; these were removed preoperatively by endoscopic sphincterotomy (ERS) in 20 patients, during cholecystectomy in 46 patients, and postoperatively by ERS in 4 patients. In six patients, common duct stones became apparent 1 to 4 months after cholecystectomy. We conclude that trained general surgeons can perform laparoscopic cholecystectomy safely with risks comparable to those for conventional open cholecystectomy.

For removal of the gallbladder, it is generally agreed that laparoscopic cholecystectomy (use of a scope inserted through a small incision in the abdomen) is less traumatic for the patient than the traditional open abdominal surgery. Laparoscopic cholecystectomy is a minimally invasive procedure which requires only four very small (1/2 inch or smaller) abdominal incisions. With this procedure, the patient is able to leave the hospital sooner than after open cholecystectomy and has a shorter recovery. But this expected shorter convalescence, as shown by an earlier return to work and normal activities, has not been fully documented. A study was undertaken to determine the recovery period for patients following laparoscopic cholecystectomy, with particular attention paid to time of return to work and preoperative physical activities. There were 104 French patients and 84 American patients studied. Within two weeks, the postoperative discomfort was gone for 73 percent of the French and 93 percent of the American patients, and normal home activities had been resumed by all but 11 French patients and five Americans. Of the 35 American and 40 French patients who worked outside the home, 63 percent of the Americans and 25 percent of the French returned to work within two weeks. Five Americans (14 percent) and 12 French (30 percent) did not return to work until four or more weeks after surgery. The level of physical work correlated with the time off from work; however, six patients (including construction workers) who did heavy labor returned to work within one week of surgery. Many of the French and some of the Americans were allowed six to eight weeks of paid sick leave. These findings show that early return to work is possible, but that cultural norms greatly influence a patient's beliefs about when he should return to work. All but one of the 136 patients said they would recommend this procedure to others facing cholecystectomy. (Consumer Summary produced by Reliance Medical Information, Inc.)
