Mucormycosis is an acutely malignant fungal disease causing local thrombosis and infarction. Gastrointestinal infection most commonly occurs in diabetics or in the immunologically compromised. This case demonstrates the radiological appearances of the gastrointestinal lesion and prolonged survival with amphotericin-B therapy.

In a 25 month study of massive upper-gastrointestinal hemorrhage, 64 patients were shown to have esophageal varices on emergency endoscopy. Twenty-four patients were actively bleeding from varices and were treated with a Sengstaken tube, and in 22 this was followed by emergency injection sclerotherapy using a rigid esophagoscope and general anesthesia. These 22 patients were followed prospectively and had 51 episodes of endoscopically proven active bleeding from esophageal varices which required Sengstaken tube control of hemorrhage during 36 separate admissions. This group included our total experience of injection sclerotherapy in acute variceal bleeding. The majority (14 of 22 patients) had alcoholic cirrhosis. Definitive control of variceal bleeding during the period of hospitalization was achieved in 33 hospital admissions (92%), usually with a single injection (27 hospital admissions: 75%). The results were satisfactory in 26 hospital admissions (72%). There were nine deaths (41% overall patient mortality rate), but no patient died primarily of variceal bleeding, and exsanguinating variceal bleeding was no longer a problem. The mortality rate per injection was 18%, and the mortality rate per hospital admission was 25%. Injection sclerotherapy is proposed as the emergency treatment of choice for patients with proven bleeding esophageal varices who do not stop bleeding on initial conservative treatment.
The preliminary results of the first 25 months of a prospective randomized controlled clinical trial, designed to compare repeated injection sclerotherapy with conservative medical management in the long term treatment of all patients shown to have previously bled from esophageal varices, are presented in detail. To date, 31 patients have been randomized, 15 in the chronic injection group and 16 in the control medical management group. In addition, five patients excluded for geographic reasons have been injected out of trial. Ethanolamine oleate has been injected into the varices, using a modified rigid esophagoscope under general anesthesia. The preliminary results have been encouraging. It has been possible to eradicate esophageal varices in the chronic injection group and, once the varices had been eradicated, no patient had recurrence of variceal bleeding. On the other hand, recurrent variceal bleeds have remained a continuing problem in a number of the patients in the control study. A longer follow-up period will be required to assess both the quantitative and the qualitative aspects of survival and to determine how long esophageal varices will remain eradicated as well as how frequently repeated injections will be required.
