Postoperative electrolyte and mineral balance was studied in nine patients with ulcerative colitis who underwent restorative proctocolectomy with ileoanal reservoir (J-pouch). The study was carried out during the first seven days of bowel function after construction of the reservoir and temporary ileostomy, and again after the ileostomy was closed and bowel continuity re-established. Stool volume and intestinal sodium excretion were reduced by respectively 40 and 45% after ileostomy was closed (p < 0.05), but potassium excretion was unchanged. The concentration of sodium was higher in ileostomy effluents, whereas the concentration of potassium was higher in stools after the ileostomy was closed (p < 0.05). Significant changes in blood and urinary electrolytes or minerals were not recorded. It is concluded that a major reduction in stool volume and intestinal excretion of sodium is already present in the early postoperative period after bowel continuity has been re-established.
对9例行回肠肛管储袋肛管吻合术（J型储袋）的溃疡性结肠炎患者术后的电解质和矿物质平衡进行了研究。该研究在储袋构建和临时回肠造口术后肠道功能的前7天进行，在回肠造口关闭且肠道连续性恢复后再次进行。回肠造口关闭后，粪便量和肠道钠排泄量分别减少了40%和45%（p<0.05），但钾排泄量未改变。回肠造口流出物中的钠浓度较高，而回肠造口关闭后粪便中的钾浓度较高（p<0.05）。血液和尿液中的电解质或矿物质未记录到显著变化。结论是，在肠道连续性恢复后的术后早期，粪便量和肠道钠排泄量已大幅减少。
