Laparoscopic cholecystectomy removes the gallbladder through three or four puncture wounds in the abdominal wall. The technique reduces the recuperative time to full activity, from as long as 4 wk to as little as 3 days, compared with conventional cholecystectomy. We herein present our initial experience with this procedure. In this series of 111 laparoscopic cholecystectomies, there were no mortalities and only one morbidity. Thirty-nine patients (35%) had a history of prior abdominal surgery. Fourteen underwent laparoscopic lysis of adhesions. Intraoperative cholangiograms were performed in 24 patients (21%), demonstrating choledocholithiasis in three. Two of the three patients underwent postoperative endoscopic retrograde cholangiopancreatography (ERCP); in the other, laparoscopic common bile duct exploration was performed. In each case, the common bile duct (CBD) was completely cleared of stones. Incidental laparoscopic appendectomy was also performed in three patients. The average time for completion of laparoscopic cholecystectomy in cases of chronic cholecystitis was 40 min. If the gallbladder was acutely inflamed, the procedure took a mean of 126 min. This series had a higher percentage of patients (19%) with acute cholecystitis then previously reported; therefore, the 2% conversion rate in this series emphasizes the broad applicability of the technique. The average length of stay in the hospital was 1.4 days, and patients returned to work in about 7 days.

Acute appendicitis is still a difficult diagnosis to make. Reports place the rate of incorrect diagnosis--the rate of negative laparotomy--at 15 to 42 per cent. This study is a prospective analysis of barium enema (BE) examinations performed upon 101 patients who presented with a history accompanied by signs and symptoms suggestive of, but not clearly diagnostic of, acute appendicitis. The over-all accuracy rate was 91.5 per cent. Sensitivity and specificity rates were 83 and 96 per cent, respectively. BE had a positive predictive value of 88 per cent and a negative predictive value of 95 per cent in this study. No complications resulted from the use of BE in this study, which included three instances of perforated appendicitis. We conclude that emergent BE is an inexpensive, safe and readily available adjunct to the diagnosis of acute appendicitis. Its use in the presence of a clear-cut presentation of acute appendicitis is not necessary. When clinical data were equivocal, BE reduced the rate of negative laparotomy to 7.2 per cent.

A unique case of exercise-induced spontaneous thrombosis of the spermatic vein that presented as an incarcerated left inguinal hernia is described. This entity may be clinically indistinguishable from many surgical conditions. Venography of the spermatic vein can be diagnostic but it should not delay surgical intervention.

A patient with a large tumor of the head and body of the pancreas had a Whipple procedure performed after the intraoperative diagnosis of "mesenchymal tumor" was made. The final histopathologic diagnosis was malignant fibrous histiocytoma arising in the pancreas. The patient died of postoperative complications, and no metastatic disease was found at autopsy. This is the first detailed description of a primary pancreatic malignant fibrous histiocytoma.
