Abdominal aortic aneurysm and retroperitoneal fibrosis. Ultrasonographic diagnosis and treatment.

Until changes of ureteric or vascular compromise are noted, retroperitoneal fibrosis usually goes unnoticed. When symptomatic retroperitoneal fibrosis has been associated with abdominal aortic aneurysm, ureteral involvement has uniformly been present. Three cases demonstrate a new ultrasonographic picture that can aid in early identification of retroperitoneal fibrosis before complications are manifest. In patients with abdominal aortic aneurysms, routine sonography may identify unsuspected retroperitoneal fibrosis, a factor that may be important in preoperative planning for safe surgical intervention.

Ureteral pathology associated with aortic surgery: a report of three unusual cases.

Intravenous pyelography is a necessary prerequisite to safe aortic surgery. Although urological complications of aortic pathology have been recognzized for 30 years, visualization of the urinary tract has not necessarily been routine practice in preoperative planning. With increasing frequency of aortic reconstruction, careful preoperative evaluation will continue to lower morbidity and mortality rates. Three unusual cases--one of perigraft ureteral fibrosis causing obstruction, one of ureteral obstruction due to retroperitoneal fibrosis, and one of ureterocutaneous fistula in a patient with an infected aortic prosthesis--are reviewed. These uncommon problems support the contention that information gained from routine excretory urograms will aid in careful preoperative assessment. Furthermore, the intravenous pyelogram will facilitate early recognition of postoperative urological complications.

Ablative surgery for necrotizing pancreatitis.

We have confirmed again that bile and trypsin injected in dogs under high pressure produce highly lethal necrotizing pancreatitis responsive to fluid resuscitation. Animals undergoing pancreatectomy show a reduction in serum amylase levels and hemoconcentration (reflected in hematocrit levels) after pancreatectomy, an effect that may be related to removal of the source of vasoactive substances liberated in pancreatitis. Qualitatively, survivors of pancreatectomy exhibit accelerated convalescence. Pancreatectomy, however, does not increase survival once the disease process is established and may be harmful. This experimental study does not support the clinical use of pancretectomy but rather emphasizes the utility of adequate fluid resuscitation in the treatment of severe pancreatitis.

Ergotism.

Severe extremity ischemia developed in four patients who had ingested methysergide maleate or ergot for the relief of headache. Symptoms involved the upper extremity in two patients and the lower extremity in two. Spontaneous reversal of the ischemic picture was obtained by simple discontinuation of ergot in most instances, although intra-arterial vasodilators were used in one case. Angliography disclosed arterial spasm and was a useful adjunct in confirming the cause of ischemia in each of the patients. It was especially useful when a history or ergot ingestion was not immediately available.

Risk of recurrence of colon polyps.

At Wood Veterans Administration Center, 268 patients who had a polypectomy have been followed up to 20 years with semiannual proctosigmoidoscopic and barium enema examinations. For the present review of benign polyp disease, patients having coexisting carcinoma, chronic inflammatory disease, and those lost to followup have been excluded; 154 patients followed for a mean of 7 years comprise the study group. Thirty per cent of patients developed recurrent polyps. The risk of recurrence during the first year was 16 times that expected in a population of similar age and sex, but thereafter diminished steadily. After 48 months risk of polyp recurrence was little higher than the incidence expected in a normal population. Neither patient age, presenting symptoms nor the site or size of the initial polyp(s) were of any prognostic value regarding recurrence. Patients presenting with a villous adenoma or with more than 3 polyps had a significantly increased risk of recurrence may persist indefinitely. The overall incidence of colonic carcinoma may have been increased, but the location of subsequent cancer was not related to the site of a previously excised polyp.
