The possibility that the composition of amniotic fluid is significantly altered with fetal intestinal obstruction was examined in 15 normal, 15 sham operated and 15 ewes in which jejuno-ileal atresia was created by devascularizing a 15 cm intestinal segment in the fetus at 90--100 days gestation. Samples of amniotic fluid for osmolality, urea N, creatinine, electrolytes, amylase, lipase, bilirubin, and proteins were obtained at 100 days gestation and at C-section performed 5 days prior to the anticipated date of delivery. One sham operated and four operated fetuses aborted prior to term for an 83% overall fetal survival rate. All surviving operated animals had total intestinal obstruction with the classical appearance of jejuno-ileal atresia. The volume of amniotic fluid at term varied from gelatinous material to as much as 1.0 liter of clear yellow to dark orange fluid. Amniotic fluid composition in term animals was not significantly different from those at 100 days gestation when the creatinine was below 15 mg%. However, sodium and chloride were significantly elevated in all groups at term when the creatinine was above 15 mg%. The osmolality and urea N in the latter group was not significantly different from animals at 100 days gestation. The amylase, lipase, total proteins, albumin, total and direct, and bilirubin in control animals at term was not significantly different from sham operated and experimental subjects. This study suggests that routine amniocentesis in the "high risk" patient would not be diagnostic of fetal intestinal obstruction.

Macroamylasemia, characterized by hyperamylasemia and a normal urinary amylase, has no known specific clinical symptoms. The disparity in serum and urinary amylase levels is due to a macromolecular amylase complex too large for glomerular filtration. This syndrome is presented in a patient with cholecystitis and a partial small bowel obstruction accompanied by persistent pre- and postoperative hyperamylasemia with proven macroamylasemia. The renal amylase clearance to creatinine clearance (CAM/CCR) ratio confirms this hyperamylasemic entity.

We report a 3-year analysis (1986 to 1989) of the management of 63 home parenteral nutrition patients, 40 with short-bowel syndrome and 23 with chronic intestinal obstruction with or without intestinal resection. Intravenous fluid requirements varied from 0.9 to 6 L/day, and the content of glucose varied between 46 and 531 g/day, protein varied from .0 to 85 g/day, fat from .0 to 100 g/day, sodium from 37 to 695 mEq/day, potassium from 30 to 220 mEq/day, chloride from 60 to 760 mEq/day, and acetate from 0 to 200 mEq/day. Body weight was normalized and well maintained in the majority of patients, but using the strict definition of deficiency as the presence of one abnormal value during 3 years, more than half had abnormal plasma chloride, glucose, alkaline phosphatase, serum glutamic oxaloacetic transaminase, total protein, albumin, selenium, and iron concentrations, and more than a third had low calcium, magnesium, vitamin D, and vitamin C levels. Normochromic anemia was seen in 73% and high blood creatinine associated with low urine volumes in 42%. Most (78%) returned to relatively normal lifestyles, but employability was occasionally impaired by loss of third-party insurance coverage resulting from a therapy that may cost $100,000 per year. Overall mortality was low (5% per year), but 73% needed readmission to hospital, mainly for suspected catheter sepsis. The results indicate that home parenteral nutrition has allowed many patients to survive gut failure and return to work but problems with chronic fluid, electrolyte and micronutrient deficiencies, catheter sepsis, and insurance coverage often restrict optimal rehabilitation.

1. We found in a prospective study with routine laboratory tests: As a single test only amylase is of certain value, but there are 27% false positive results in peritonitis and intestinal obstruction. 2. Our standardized program can help to evaluate disturbed vital functions and so far improve pre- and postoperative treatment. 3. A high risk is given by simultanously alterated acid-base-balance, blood sugar and creatinine; but these findings are showing shock, not acute abdomen. 4. Laboratory procedures are of no help to the practitioner; they must not delay the early lifesaving operation.

Between April 1985 and April 1993, 100 consecutive men underwent lower urinary tract reconstruction after cystectomy. An ileal low pressure reservoir using the Goodwin cup-patch principle was combined with an afferent ileal tubular segment. The early complication rate was 11%, including 2 postoperative deaths due to septicemia. After a median followup of 27 months (range 3 to 96) 14 patients required surgery for late complications (intestinal obstruction, urethral stricture or tumor recurrence, hernia or ureteral stenosis). A total of 32 patients died of metastatic bladder cancer and 7 died of other causes. The functional capacity of the bladder substitute was increased to the desired 450 to 500 ml. after 3 to 12 months, which was paralleled by improving urinary continence. After 1 year 92% of the patients were continent by day and after 2 years 80% were continent at night. Upper tract surveillance with excretory urography, renal ultrasound and serum creatinine estimation has shown 4 left ureteral strictures but not significant upper tract deterioration or ureteral recurrence. Significant reflux was not observed during video urodynamics unless the reservoir was overfilled. During voiding, by outlet relaxation and straining if necessary, the intra-abdominal pressure increase with straining acted equally on the reservoir and ureters. Therefore, unlike voiding with a normal bladder, no isolated intravesical pressure increase occurred and, thus, there was no reflux from the reservoir. The combination of an ileal low pressure reservoir with an afferent isoperistaltic ileal segment and an open end-to-side ureteroileal anastomosis allows for radical cancer surgery with resection of the ureters where they cross the iliac vessels and minimizes the risk of ureteral stenosis. The unidirectional peristalsis of the ureters and the afferent tubular ileal segment seem to protect the upper urinary tract sufficiently. The surgical technique is straightforward and allows for later conversion to an ileal conduit if necessary. The functional results of the bladder substitute are comparable to other similar reservoir techniques, provided that the patients are carefully selected, well rehabilitated and meticulously followed.

Congenital duodenal webs are rare lesions, usually detected during early infancy because of signs of high intestinal obstruction. The occasional patient escapes both symptoms and detection until adolescence or adulthood. This report concerns two cases of congenital duodenal web at different ages and with different clinical manifestations. Case 1, a six-month-old male, was admitted because of abdominal distention and vomiting. Case 2, a 13-year-old boy, was referred here for further evaluation of recurring seizure attacks, elevated blood urea nitrogen and creatinine and hyponatremia. Duodenotomy and excision of the web performed for both patients. Complete amelioration of all symptoms was then observed at Outpatient Clinic follow-up for one year.

During the past 20 years, 31 ureterocutaneostomies (UC), 101 ileal conduits (IC) and 107 colonic conduits (CC) were performed. In the UC group, most of the patients were aged or had unresectable invasive pelvic malignancies. The operative mortality was 6.5% and acute pyelonephritis was noted frequently (48.3%). Stomal stenosis also developed significantly (63.5%). The operative mortalities in the IC group and CC group were 6.9% and 9.3%, respectively. Although the incidences of bowel obstruction, bowel fistula and renal calculi were higher in the IC group (18.8% vs 7.5% and 6.9% vs 0%, respectively). The serum creatinine level was lowest in the CC group (0.90 +/- 0.46 mg/dl) and highest in the UC group (1.36 +/- 0.75 mg/dl). Conduit ureteral reflux was frequent in the UC group (66.7%) but rare in the CC group (1.3%). We conclude that UC should be indicated in the selected patients with high risk, and IC and CC are indicated in patients who may have good prognosis but not indicated for continent reservoir or neobladder. We prefer CC in the younger group.

We report a 73-year-old Japanese woman with familial Parkinson's disease. The patient was well until her 67 years of the age, when she noted rest tremor in her right hand. Soon after her gait became short stepped. She visited our clinic on October 6, 1992 when she was 68 years old. She was alert and well oriented without dementia. She showed masked face, small voice, small stepped gait, retropulsion, resting tremor in her right hand, rigidity in the neck, and bradykinesia. She was treated with 400 mg/day of levodopa-carbidopa, which improved her symptoms, however, she developed wearing off phenomenon 3 years after the initiation of levodopa treatment. On August 26, 1998, she developed abdominal pain, diarrhea, and vomiting. She was admitted to another hospital, where abdominal plain x-ray revealed an evidence of intestinal obstruction (ileus). She was treated with nasogastric suction and intravenous fluid. Her condition did not improve and she was transferred to our hospital on August 29, 1998. Her family history revealed no consanguineous marriage. She had two elder brothers and three elder sisters. One of her brothers had been diagnosed as Parkinson's disease. Her husband also suffered from Parkinson's disease, however, her parents apparently did not have Parkinson's disease. On admission, she appeared to be drowsy. Her blood pressure was 102/70 mmHg, body temperature 36.2 degrees C. The lungs were clear and no cardiac murmur was present. Abdomen was flat and bowel sound was audible. No abnormal mass was palpable. Neurologic examination revealed mild consciousness disturbance, masked face, and small voice. No motor paralysis was noted. Muscle tone was hypotonic. No abnormal involuntary movement was noted. Abnormal laboratory findings on admission were as follows; WBC 11,300/microliter, amylase 1,373 IU/l, CK 446 IU/l, BUN 50 mg/dl, creatinine 1.17 mg/dl, CRP 22.7 mg/ dl, Na 134 mEq/l, K 3.1 mEq/l, and Cl 81 mEq/l. A chest x-ray film revealed pneumonic shadows in both lower lung fields. She was treated by nasointestinal suction, intravenous fluids, and chemotherapy for her infection. Her BP started to drop on September 2 and she developed cardiac arrest on the same day. She was discussed in a neurological CPC. The chief discussant arrived at the conclusion that the patient had a form of autosomal dominant familial Parkinson's disease. As parents did not have Parkinson's disease, some of the participants raised the possibility of autosomal recessive inheritance. But the age of onset was too late for autosomal recessive inheritance. Majority thought that the mode of inheritance was autosomal dominant with low penetrance. alpha-Synuclein mutation causes an autosomal dominant familial Parkinson's disease, but this type is very rare in non-Greek populations and the penetrance is high. Chromosome 2-linked autosomal dominant familial Parkinson's disease shows low penetrance. There are many other autosomal dominant forms of familial Parkinson's disease linked to yet unknown chromosome loci. Majority thought that this patient also had a form of Lewy-body positive autosomal dominant familial Parkinson's disease of unknown chromosome locus. Post mortem examination revealed ischemic intestinal lesion with strangulation. This was thought to be the cause of her death. In the central nervous system, the brain appeared to be normal by inspection. In the coronal sections, the substantia nigra and the locus coeruleus showed marked depigmentation. Histologic examination revealed marked neuronal loss and Lewy body formation in the remaining neurons. Pathologic examination was consistent with Parkinson's disease. Mutational analysis for the parkin gene was negative.

Volvulus of the small bowel is not so frequent as is volvulus of the colon. A delayed diagnosis and surgical treatment result in high rate bowel infarction which can lead to perforation and stercoral peritonitis. If perforation does not take place, the infarcted bowel has to be resected causing multiple complications and mortality. The small bowel volvulus is caused by mesenteric lipoma in about 5% of cases. We present a 77-year-old man operated on for intestinal obstruction. The patient was admitted in a serious condition with a five-day history of abdominal pain and vomiting. On admission he vomited a small bowel content (miserere), he was dehydrated and with high blood urea and creatinine values. Plain X-ray showed a number of air fluid levels in the small bowel. At operation a small bowel volvulus caused by mesenteric lipoma (18 x 11 x 10 cm in diameter) with bowel infarction but without free perforation and peritonitis, was found. The tumour was removed together with 10 cm of resected bowel with end-to-end anastomosis. The recovery was uneventful. The patient is still symptom free.

Newer, minimally invasive catheter-based endovascular technology utilizing stent grafts are currently being evaluated for abdominal aortic aneurysm (AAA) repair. A retrospective review of all (3 years) consecutive, non-ruptured elective AAA repairs was undertaken to document the results of AAA surgical repair in a modern cohort of patients to allow a contemporary comparison with the evolving endoluminal data. One hundred twenty-one AAAs were identified in a male veteran population. Mean age was 68.5 +/-7.7 years. Medical history review showed hypertension in 55%, heart disease in 73.5%, peripheral vascular disease in 21%, stroke and transient ischemic attacks in 22%, diabetes mellitus in 7%, renal insufficiency in 10%, and smoking history in 80%. The AAA size was documented with ultrasound (5.2 +/-1.3 cm, n=40) and computed tomography (5.6 +/-1.3 cm, n=100). Fifty-nine percent had angiography. Intraoperative end points included an operative time of 165 +/-6.3 minutes from incision to dressing placement. A Dacron tube graft was used in 78%, the remaining were Dacron bifurcated grafts. A suprarenal clamp was used in 8% for proximal aortic control with juxtarenal aneurysms. A pulmonary-artery catheter was placed in 69%. A transverse incision was used in 69% of patients and a midline incision was used in the rest. Estimated blood loss was 1505 +/-103 mL; cell saver blood returned 754 +/-53 mL; crystalloid/Hespan 4771 +/-176 mL; banked packed red blood cells 0.75 +/-0.11 U. Time to extubation was, in the operating room (78.5%), on the day of the operation (5.0%), postoperative day (POD) 1 (12.4%), POD2 (1.7%), POD3 (0.8%), and one case was performed with epidural anesthesia only. Postoperative end points included a 30-day mortality rate of 1.6% (two patients). Postoperative morbidity included wound dehiscence 0.8%; sepsis, urinary tract infection, wound infection, leg ischemia, ischemic colitis, and stroke each had an incidence of 1.6%; myocardial infarction, congestive heart failure, pneumonia, re-operation for suspected bleeding, and ileus or bowel obstruction occurred with an incidence of 3.3%. No significant increase in serum creatinine levels was noted. Time to enteral fluids/nutrition was 3.5 +/-0.08 days. Patients were out of bed to a chair or walking by 1.3 +/-0.06 days postoperatively. The length of stay in the intensive care unit (ICU) was 2.0 +/-0.12 days and postoperative hospital stay was 6.6 +/- 0.33 days. Transfusion requirement for the hospital stay was 1.6 +/-0.2 U per patient. This review highlights a cohort of male veteran patients with significant cardiac co-morbidity who have undergone repair with a conventional open technique and low mortality and morbidity rates. This group had rapid extubation, time to oral intake, and ambulation. In addition, ICU and hospital stays were relatively short.
