[Short-term tolerability of 2 types of termino-terminal jejuno-ileal bypass]

The short-term tolerability of two types of end-to-end jejuno-ileal bypasses with different distal ileal loop lengths was evaluated. A comparison was made for 20 days of the behaviour of the main parameters influenced by the malabsorption syndrome thus induced. It was found that the operation involving a greater loss of small intestine was burdened with a greater number of discharges per day, an increase in total water loss, and an elevatem operative risk. This was compensated by more rapid and more evident loss of weight. Evaluation of the real meaning of the inversion of the A:G ratio observed in the short term with this type of operation was postponed to allow a longer follow-up period to run.
