Cholangiocarcinoma accounts for about 1% of all malignant tumors. They are difficult to diagnose because of their small size and their location. Although surgical resection is the best therapeutic approach, most patients undergo unnecessary exploratory laparotomy due to incorrect preoperative diagnosis.

We present our experience with laparoscopic ultrasound (LU) in the evaluation of cholangiocarcinoma and determination of tumor spread and vascular involvement. Of 25 patients referred for surgery, 6 were excluded following LU and were referred instead for palliative treatment. Diagnosis of the tumor was successful in 92%, and vascular involvement was diagnosed in 46%. LU should be an integral diagnostic test in the evaluation of choriocarcinoma.

We evaluated the significance of first visits to our pulmonary clinic with regard to diagnosis and treatment by reviewing records of 287 new referrals by medical care providers (Sept. 1998 - Feb. 1999). At the first visit the diagnosis was changed in 30%, and treatment in 40%. These are minimal figures because evaluation had not been completed nor the diagnosis determined in all cases, while further investigation and follow-up continued.

In light of these findings, we believe that recent pressure on primary care physicians to avoid referrals to specialty clinics would result in short-term savings, but in the long term, would increase expenses and diminish quality of care. It is important to consider ways to maximize the interaction between the primary care physician and the specialist to maintain quality of care and decreases costs.

There are 2 stages of alopecia, anagen and telogen effluvium, both of which may be associated with medication- related alopecia. We describe massive hair loss in a 51-year-old woman during treatment with Seroxat (paroxetine), which remitted after it was discontinued. Pathological mechanisms of drug-associated alopecia are complex and have yet to be fully elucidated.

Recurrent Anaphylactic Reactions During Hospitalization – an Unusual Etiology

The prevalence of hypersensitivity and untoward reactions to natural rubber latex (NRL) products is increasing, particularly among specific risk groups. A young man aged 23 years who experienced several episodes of allergic reactions, 2 of which included anaphylactic shock during hospital admission, is presented. These episodes were initially attributed to intravenous medication, but were most probably caused by inadvertent exposure to latex.

Medical facilities may contain large amounts of latex, and therefore present a hazardous environment for sensitive people. Increasing awareness of latex sensitivity among patients-at-risk and medical personnel, and implementing simple prophylactic measures, may reduce morbidity and mortality. We propose simple and practical guidelines for diagnosis and treatment.

Psychogenic Polydipsia Leading to Water Intoxication

Psychogenic polydipsia and its frequent complication, water intoxication, are well-known to psychologists. There are biochemical and psychiatric theories of psychogenic polydipsia which often correlate with each other.

A 48-year-old man with chronic paranoid schizophrenia developed symptoms of psychogenic polydipsia. This provoked disturbances in electrolyte balance, resulting in a rapid decrease in serum sodium concentration and eventual death. There is a paucity of information and little awareness of this problem in the professional literature.

Pancreatic lesions present a diagnostic challenge. Even modern imaging techniques are not sensitive enough in determining resectability of pancreatic tumors. A substantial proportion of patients therefore undergo unnecessary surgical exploration. We determined the impact of laparoscopy and laparoscopic ultrasound (LAPUS) examinations on surgical decision-making in 60 patients with pancreatic lesions.

Of 48 with solid pancreatic lesions, 22 were defined by LAPUS as having nonresectable tumors, while conventional imaging studies defined only 9 of them as such. 3 of these 9 underwent successful resections of the pancreatic mass. Surgical intervention was ruled out by LAPUS in 16 patients (33.3%) but 26 had resectable lesions of whom 25 underwent surgery. 3 of this group were found to have nonresectable tumors at surgery, a false-positive rate of 6.2%. Overall sensitivity of LAPUS in our series was 88%.

In 12 patients with cystic pancreatic lesions LAPUS contributed significantly to the preoperative decision due to clear imaging of the cystic lesion. Additional information was obtained from ultrasound guided-biopsy of the cyst wall, as well as determination of tumor-marker levels in the cystic fluid aspirate. LAPUS contributed significantly to operative management in 58%.

Laparoscopy for Common Bile Duct Stones

We performed 75 laparoscopic cholecystectomies during July and September 1996. In 3 men and 4 women, aged 32-87 years, there was obstructive jaundice caused by choledocholithiasis. During laparoscopy in the jaundiced patients, calculi were identified by cholangioscopy and intra-operative cholangiography. They were washed into the duodenum (confirmed cholangiographically) after intravenous glucagon injections and dilation of the papilla of Vater.

Serum bilirubin and liver enzyme levels returned to normal within a few days. There was no operative or postoperative morbidity, nor any biliary-related systemic complications. Average postoperative hospitalization was 3 days.

Bouveret's syndrome involves gastric outlet obstruction caused by a gallstone in the duodenum. This type of gallstone ileus can be diagnosed and treated endoscopically. Endoscopic stone removal is especially indicated in poor risk patients. A dislodged impacted stone can migrate distally and cause small bowel mechanical obstruction. We report a 51-year-old woman who underwent endoscopic duodenal stone manipulation which resulted in small bowel obstruction.

The Fate of Gallstones "Dropped" during Laparoscopy

Laparoscopic cholecystectomy is considered the procedure of choice for removing symptomatic, stone-containing gallbladders. It is estimated that in 30-40% of these operations stone(s) spill into the peritoneal cavity. It was assumed that these "dropped stones" are harmless and are dissolved and absorbed spontaneously. We present a 70-year-old woman in whom such a stone, dropped during laparoscopy, led to formation of an intraperitoneal abscess.

Laparoscopic cholecystectomy is the "gold standard" in treating cholelithiasis. Stones are frequently lost in the peritoneal cavity during the procedure, but "missing stones" have been regarded as insignificant. However, there is accumulating evidence that untreated "lost" stones may cause complications even years after operation.

We present a 65-year-old woman who presented with vague complaints, anemia and an elevated ESR. CT scan showed an infiltrating process in extra-abdominal muscles compatible with sarcoma. At operation, 2.5 years after previous laparoscopic cholecystectomy, an abscess was found which contained biliary stones. Because of their small size they were not visible on CT scan. We discuss the possible ways of handling "falling stones."

Spontaneous internal jugular thrombosis is a rare vascular disorder. It usually occurs as a result of external pressure due to a tumor, infection or as a result of damage to the vessel wall after trauma or central venous catheterization. We report a 35-year-old woman who suffered from severe pulmonary hypertension due to chronic cystic lung disease. She was admitted due to sudden, severe, right-sided neck pain. Internal jugular occlusion by a thrombus was demonstrated by ultrasound and CT-scans but no apparent cause was found. We postulated that the important factors in the development of her thrombosis were stasis due to pulmonary hypertension and high blood viscosity.

In a study examining the relationship between patient participation in clinical decision making and levels of anxiety, patients were offered a choice of treatment for ureteral calculus. 42 received information about 2 treatment options, ultrasound fragmentation of the stone through a ureteroscope and extracorporeal shock wave lithotripsy (ESWL), and were asked to choose the method that they preferred. 54 received treatment decided on by the physician without their participation in the decision making process. Anxiety was measured before meeting with the physician, immediately after the meeting and on hospitalization for treatment. The contribution of the patient's perception of participation in the decision- making process and level of education was also examined. There was a decrease in level of anxiety after meeting with the physician only among those who did not actually participate in the decision-making process (p<0.05). There was no change in the level of anxiety among those offered choice of treatment. However, a decrease in anxiety was evident among patients who perceived that they had received information about their illness and its treatment (p<0.01). This was not the case for patients who perceived themselves as participants in decision making unless they had a relatively high-level of education (p=0.05).
