סרקואידוזיס היא מחלה גרגירומתית (Granulomatotic) רב-מערכתית המערבת בעיקר את הריאות ואת המערכת הלימפטית. מעורבות דרכי העיכול והלבלב בסרקואידוזיס היא נדירה, והופעת גוש בלבלב כביטוי ראשוני למעורבות המחלה בדרכי-העיכול תוארה לעיתים נדירות בלבד.

ביטוי ראשוני בלבלב מחשיד לממאירות אז לדלקת, מקשה בקביעת האבחנה של סרקואידוזיס ולרוב מסתיים בניתוח.

במאמר הנוכחי מדווח על פרשת חולה עם מעורבות של הלבלב, דרכי המרה והבלוטות בפדר (Mesenterium) שהצריך ניתוח על שם Wipple, ובביופסיות שהותקנו מאיברים אלה הודגמו גרגירומות (Granulomas) ללא נמק גבינתי וללא עדות לממאירות.

לנוכח הקושי באיבחון סרקואיד של דרכי העיכול והלבלב, מובאת במאמר זה גם סקירה של הספרות הרפואית בנושא האיבחון והטיפול בהסתמנות זו של המחלה.

קיימות מספר תופעות נירולוגיות שדווח עליהן בהקשר למחלת הכרסת (celiac disease) הן במבוגרים והן בילדים. בעבר נקשרו תופעות אלה לחסרים תזונתיים, ומאחר שהן מאובחנות גם בחולים שאינם לוקים בחסרים תזונתיים, הועלה חשד למנגנון חיסוני או רעלני (toxic). המטרה במאמר סקירה זה היא להביא את הנתונים הידועים בספרות על ההסתמנות העצבית של מחלת הכרסת בכלל ועל הידוע לגבי ילדים בפרט.

הקאה דמית או שיחרה (melena) כעדות לדמם ממערכת העיכול העליונה, אינה איוע נדיר. מדובר בתסמין הראשון המופיע בעשרה עד עשרים אחוזים מהחולים עם התכייבות בקיבה או בתריסריון. למרות זאת, אין הסכמה ברורה (consensus) לגבי שלבי האיבחון והטיפול. עד לאחרונה התבסס הטיפול על ייצוב המודינמי של החולה ועל מתן חוסמים לקולטני היסטאמין מסוג H2. הטיפול התרופתי ניתן לתוך הווריד כל עוד החולה מחובר לצנתר, ובהמשך הוא מוחלף לטיפול בחוסמי תעלות פרוטון בדרך פומית. הפעולה האיבחונית והטיפולית העיקרית המבוצעת בחולים אלה היא אנדוסקופיה.

רקע: שאתות במשתית (stromal tumors) של דרכי-העיכול הן ממאירויות לא שכיחות. קיימים בספרות הרפואית חילוקי-דעות בנוגע לגורמי-הסיכון ולדרכי הטיפול בלוקים במחלה זו.

מטרה: עבודה רטרוספקטיבית לקביעת תוצאות הטיפול, שיעור הישרדות וגורמי-סיכון קליניים ופתולוגיים בחולים עם שאתות במשתית בקיבה, בתריסריון, במעי הצם (jejunum), במעי הכרוך (ileum) ובחלחולת. תשעה חולים עברו ניתוח כריתה רחבה של השאת ובחולה אחד הכריתה לא היתה שלמה. גילם הממוצע של החולים היה 63 שנים – 7 גברים ו-3 נשים. גודל השאת הראשונית היה 4.5-17 ס"מ (ממוצע 10 ס"מ). מובאים גם נתונים פתולוגיים אחרים.

תוצאות: ממוצע ההישרדות של החולים היה 43 חודשים: 4 חולים שרדו 87 חודשים בממוצע ללא הישנות המחלה; חולה אחד שרד עם גרורות בכבד שהתהוו 10 חודשים לאחר הניתוח; וארבעה חולים נפטרו מהישנות המחלה, עם ממוצע הישרדות של 13 חודשים.

מסקנות: בדומה למדווח בספרות, הגורמים הפרוגנוסטיים להישנות המחלה הם שאת ראשונית <8.5 ס"מ, בשלות נמוכה של תאי השאת ומספר חלוקות <5 בחמישים שדות-ראייה מיקרוסקופיים.

Non-steroidal anti-inflammatory drugs (NSAID) are potent analgesic agents. They are indicated for rheumatoid arthritis, osteoarthritis, severe acute and prolonged chronic pain. A wide range of analgesic agents are available. The objective of this study was to assess the patient's knowledge of his illness, his knowledge familiarity with NSAID medications and their side effects and thereupon, to evaluate the awareness, utilization, satisfaction and expectations associated with current available treatment.

During the year 2000, a randomized telephone screening questionnaire, was completed over a 2 month period for a sample group of the general Israeli population over 50 years of age.

Of the 3179 persons contacted, 2028 responded and 292 persons were treated with NSAIDs and further investigated. Fifty percent suffered from chronic musculoskeletal pain, 22% had osteoarthritis, 10% had rheumatoid arthritis, and 18% had undefined chronic pain. The average age of the respondent was 65 years old. The average duration of treatment was 11 years. The most common drugs used by the 292 respondents that were taking NSAIDs were diclofenac (Voltaren) - 51% and naproxen (Naxyn) - 21%. Only 4% were treated with COX-2 specific inhibitors. Twenty percent of the respondents utilized more than one NSAID simultaneously. Forty seven percent of the patients had peptic ulcer disease but only 39% of them were simultaneously treated with an NSAID and a gastroprotective agent. Sixty eight percent of patients expected amelioration of symptoms while taking NSAIDs. Seventy seven percent of respondents were dissatisfied with treatment. The patients expressed that they did not have a reliable easily accessible source of information on their disorder or on available treatment options.

Many respondents were not aware of their medical diagnosis. In general, patients were not aware of all the available NSAIDs or the side effects of gastrointestinal complications. Enhancement of information available to the patient is warranted to improve the provision of efficient therapy, reduce side effects and increase patient satisfaction from therapy.

Gastrointestinal bleeding of obscure origin consists of recurrent bouts of acute or chronic bleeding for which no definite source is discovered in routine endoscopic and barium contrast studies of the upper and lower gastrointestinal tracts. Usually its cause is angiodysplasia of the intestine, but many cases are due to tumors, mostly of the small bowel, which may be malignant.

In patients under the age of 50, the proportion with malignancy is relatively high (up to 14%) as compared to older patients. We describe a 45-year-old woman who suffered from gastrointestinal bleeding for 3 years. The cause of bleeding was not found despite extensive work-up.

In her last admission for acute gastrointestinal hemorrhage she was given a total of 30 units of blood. A tumor of the small intestine found by angiography was excised and found to be a stromal tumor of uncertain malignant potential. 1 year after operation she is asymptomatic without bleeding and her hemoglobin is stable without treatment.

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%.

Intractable pain is the most distressing symptom in nonresectable pancreatic carcinoma and in chronic pancreatitis. Recently, thoracoscopic splanchnicectomy has been advocated as a minimally invasive method of pain control in these patients. Between May 1995 and April 1998, 24 patients with nonresectable pancreatic cancer and 4 with chronic pancreatitis, underwent 43 thoracoscopic splanchnicectomies. All suffered from intractable pain, were opiate-dependent and unable to perform normal daily activities. Unilateral left splanchnicectomy was done in 13 and bilateral in 15.

All procedures were completed thoracoscopically. Operative time ranged from 25 to 60 min and mean hospital stay was 3 days. Median pain intensity was reduced by 50% in 24 and no further narcotics or analgesics were required. We found thoracoscopic splanchnicectomy a safe and effective procedure for intractable pancreatic pain.

Surgery is the mainstay in the treatment of esophageal carcinoma and is effective for palliation of dysphagia. Patients unfit for surgery are difficult therapeutic problems. We evaluated photodynamic therapy for palliation of dysphagia in this condition.

Patients were given 5-aminolevulinic acid, 60 mg/kg, orally and 24 hour later gastroscopy was performed during which red light illumination (100 j/cmŽ2 for 600 seconds) was administered. This was repeated 48 hours later. The degree of dysphagia was recorded before and 14 days after treatment.

8 patients with an advanced non-resectable tumor, or who were unfit for surgery, were thus treated. 4 had squamous cell carcinoma of the mid-esophagus and 4 had adenocarcinoma of the lower esophagus. There was mild, self- limited photosensitivity in all. Liver and renal function tests and blood count were not affected by the treatment. Dysphagia was improved in all except 1 patient. A patient with early stage disease continued to eat a normal diet.

We believe that photodynamic therapy with systemic aminolevulinic acid as a photosensitizer and a non-laser light source is feasible and safe in advanced esophageal cancer. It is an effective modality for relief of dysphagia in that condition.

Prevalence of hepatitis G virus (HGV) infection in the general western population ranges from 0.2-1.5%. In high-risk groups, such as patients with chronic liver disease, hematologic disorders and drug addicts, prevalence is as high as 10%-15%. Dialysis patients have increased rates of HGV infection (6%-50%).

We evaluated prevalence of HGV infection among dialysis patients, and the association between HGV infection and hepatitis C virus (HCV) infection. Serum samples were screened for HGV infection by RT-PCR. Screening for HCV infection was performed by an EIA test and confirmed by RIBA and RT-PCR for HCV. Sera were also tested for HBV markers.

The study group included all 78 hemodialysis patients and 7 of the 12 peritoneal dialysis patients in our unit during September to November 1997. 4 (5.2%) were HGV-positive but none were peritoneal dialysis patients. 1 of the 12 HCV-positives was also infected with HGV. HGV infection was not associated with duration of dialysis, number of blood transfusions or levels of transaminases.

Prevalence of HGV infection among our hemodialysis patients was low (5.2%), but higher than reported for the general population. Prevalence of HGV/HCV infection in hemodialysis patients was low and unrelated to duration of dialysis, number of blood transfusions and levels of transaminases.

Resistance to antibiotics is considered the main reason for failure to eradicate Helicobacter pylori (HP). Resistance rates are different in developed and developing countries and are not known for Israel. We studied HP resistance rates in 40 patients who underwent esophagoduodenoscopy for various indications and were found to have gastric HP colonies.

Sensitivity was determined by E-test, using clarythromycin, amoxycillin, clindamycin, erythromycin and metronidazole. The resistance rate for metronidazole was up to 67% but that for clindamycin was only 10%. HP was very sensitive to both macrolide antibiotics, erythromycin and clarythromycin.

Traditionally Hirschsprung's disease has been treated by 2-or 3-stage procedures. During the past 6 years a 1-stage Duhamel procedure without stoma has become our treatment of choice for Hirschsprung's disease in neonates and young infants. Over a 6-year period, 15 infants and children with colonic Hirschsprung's disease were treated with the 1-stage Duhamel retro-rectal pull-through procedure without a stoma, with the Lester-Martin modification. All patients had the usual short segment aganglionosis, but 1 had a long segment which included the splenic flexure.

Early complications included wound infection in 1 and minor rectal bleeding in 3. Late complications included constipation in 1 and enterocolitis in 4. Long-term functional results were very good in all those operated except for 1 with rectal achalasia.

We conclude that Hirschsprung's disease can be successfully treated with a 1-stage pull-through operation, the child usually benefitting from the shorter hospital stay and the avoidance of a colostomy.

The National Institutes of Health (NIH) held a consensus conference which recommended 5-FU and levamisole as adjuvant chemotherapy for colon cancer MAC (Modified Astler Coller) stage C.

From 1991-1994, 37 such patients diagnosed here were treated with 5-FU (intravenous dose of 450/mg/m²/d for 5 days and from day 29, once a week for 48 weeks) and oral levamisole (50 mg 3 times/d. for 3 days, every 2 weeks for a year), as suggested by NIH guidelines.

16 patients were males and 21 were females, mean age was 62 years and median 64. Cancer locations were: right colon (in 16, 43%), left colon (19, 51%), multiple colon primaries (2, 1%). 25 (68%) had 1-3 positive lymph nodes and 12 (32%) had 4 or more positive lymph nodes.

Only 20 (54%) finished treatment as prescribed. In the others, 1 or both drugs caused side-effects for which the drugs had to be stopped. 6 patients relapsed while on treatment.

The most common side-effects were diarrhea, stomatitis and bone marrow suppression. 3 were hospitalized due to neutropenic fever. 5-year actuarial survival of all patients was 61%; 5-year relapse-free survival was 61%; 5-year relapse-free survival of right versus left colon was 41% and 82%, respectively (p<0.01). There was no significant difference in 5-year survival of those with 1-3 positive lymph nodes as compared to those with 4 or more (62% and 56%, respectively). 5-year survival in those who finished or did not finish treatment (excluding those who stopped treatment because of progressive disease) was 83% and 70%, respectively (NS).

The 5-year survival of our series was similar to that of patients treated similarly elsewhere. The 5-FU and levamisole treatment was not tolerated well by our study population. It has recently been replaced in our service by a 5-FU and leucovorin regimen given for 6 months.

Superficial Skin Necrosis in Short Bowel Syndrome

Arie Eisenman, Rafael Enat

Dept. of Medicine B, Rambam Medical Center and Rappaport Faculty of Medicine, The Technion, Haifa

Short bowel syndrome causes a complex of symptoms due to compromise of small intestinal nutrient absorption. A 60-year-old woman underwent major resection of the small intestine due to a road accident 3 years ago. The sole manifestation of short-bowel-syndrome was superficial skin necrosis due to vitamin K deficiency. She was asymptomatic for a long time, until treatment with antibiotics further intensified initially subclinical malabsorption.

It is not clear why there had been no other symptoms and why the main impact was on the fibrinolytic system rather than the coagulation system, as is usually the case. It is recommended that patients after major resection of the small intestine be closely monitored for coagulation function if an oral antibiotic is prescribed.

Conservative Approach in Abdominal Trauma in Childhood

To determine the results of the conservative approach in the treatment of pediatric abdominal trauma, we retrospectively analyzed data from the files of 95 cases of abdominal trauma in children during a 5-year period.

51 patients (54%) had isolated abdominal injury, while 44 (46%) had multiple trauma. The most common causes of injury were road accidents and falls from heights (74%). CT scans were performed in 61 (64%) with positive results in 90%. Ultrasonography was done in 22 (23%) and was positive in 55%.

The spleen was the most vulnerable intra-abdominal organ (33 patients, 35%), as well as the organ most severely damaged. Other injured organs were: liver (30 cases), kidney (16), stomach (2), large blood vessels (2), and pancreas, duodenum and diaphragm (1 case each).

83 patients (87%) were treated conservatively, while 11 were operated on for penetrating abdominal trauma (3 cases), hemodynamic instability (3), positive DPL (3), and Scale 4 splenic injury and free intra-abdominal air on CT scan (1 case each). Early and late complications were mild.

It is concluded that CT is an efficient and reliable imaging method for diagnosis and staging of severity of injury in blunt abdominal trauma. Nonoperative management of solid organ injuries under careful observation in a pediatric trauma center is safe and appropriate. Most Scale 4 splenic injuries can be treated successfully without surgical intervention. Using this conservative approach there were no late complications.
