There has not been much studies conducted to address this issue however most of the recommendations are made in view of preventing any complications following procedures. Stiegmann and Goff 4 were the first to employ EVL to treat esophageal varices. They did not mention any specific restriction of feeding on patients receiving band ligation however they did mentioned that following the band ligation of varices, the ligated varices and tissues may evoke transient dysphagia to solid food.5 A study conducted by Gin Ho Lo et al 6 demonstrated that early feeding with a liquid diet in conscious patients after successful endoscopic therapy of varices can shorten the hospital stay. The two groups which were created in this study were the early-feeding group and the delayed-feeding group. Patients in the early-feeding group were asked to fast for only 4 hours following endoscopic treatment. Subsequently, a liquid diet (fruit juice, soybean juice, milk, rice in liquid form) was instituted for 3 days. Additionally, \<500 cc intravenous fluid with proper electrolyte supplement per day was administered. Thereafter, a soft diet was provided for 3 days, after which a regular diet was resumed since the seventh day after endoscopic treatment. Patients in the delayed-feeding group were asked to absolutely fast for 48 hours after endoscopic treatment, and 1500 cc/day intravenous fluids (normal saline or glucose water) with proper electrolytes were administered for 2 days. After 2 days of fasting, a liquid diet was given for 1 day, and subsequently, a soft diet was given for 3 days, and then a regular diet was instituted on the seventh day after endoscopic treatment. If rebleeding occurred within 7 days of endoscopic therapy, patients in both groups were again asked to fast for 48 hours, and then put on a liquid diet for 1 day followed by a soft diet for 4 days.

Treatment failure was defined as failure to control acute bleeding episodes or very early rebleeding or death within 5 days. Failure to control acute variceal bleeding was defined as the occurrence of any of the following events within 48 hours of enrollment, based on the modified criteria of the Baveno III consensus:7 (1) fresh hematemesis after enrollment; (2) sudden onset of reduction in blood pressure of _20 mmHg and/or an increase in pulse rate of 20 beats/minute with 2 g drop in hemoglobin; (3) transfusion of four units of blood required to increase the hematocrit to above 27% or hemoglobin to above 9 g/dL; and (4) death. Very early rebleeding was defined as when the criteria for failure to control acute variceal bleeding occurred between 48 hours and 120 hours after enrollment in patients achieving control of acute bleeding. Control of acute bleeding (initial hemostasis) was defined as when the criteria for failure did not occur within 48 hours of enrollment. A 5-day hemostasis was defined as when the criteria for failure to control acute variceal bleeding and very early rebleeding did not occur within 5 days of enrollment. A nasogastric tube was not routinely inserted after initial endoscopy.

The rebleeding rates associated with EVL varied greatly between studies, and rates ranging from 2% to 54% have been recorded.8,9 Aside from other reasons, this discrepancy is very likely to be related to the variation in timing of refeeding after EVL. However, this factor was rarely mentioned in the methodology of these studies A review article by Xavier He´buterne 10 concluded that In patients hospitalized for acute upper gastrointestinal bleeding due to an ulcer with high risk of rebleeding (Forrest I-IIb) or with variceal bleeding it is recommended to wait at least 48 h after endoscopic therapy before initiating oral or enteral feeding. In case of ulcer with low risk of rebleeding (Forrest IIc and III) or in patients with gastritis, Mallory-Weiss, oesophagitis, or angiodysplasia, there is no need to delay refeeding, and they can be fed as soon as tolerated. Understanding the cause of the diagnosis is always necessary to adapt nutrition in patients with upper gastrointestinal bleeding.
