Postoperative bowel dysfunction following restorative proctectomy, commonly referred to as Low Anterior Resection Syndrome (LARS), is a common long term sequela of rectal cancer treatment. While many of the established risk factors for LARS are non-modifiable, others may be well within the surgeon’s control. Several pre-, intra-, and postoperative decisions may have a significant impact on postoperative bowel function. Some of these factors include the extent of surgical resection, surgical approach, choice of anastomotic reconstruction, and use of fecal diversion. This review article summarizes the available evidence regarding how surgical decision-making can affect postoperative bowel function.
直肠癌保肛术后肠道功能障碍,通常称为低位前切除综合征(LARS),是直肠癌治疗后常见的长期后遗症。尽管LARS的许多已知风险因素不可改变,但其他因素可能完全在外科医生的控制范围内。多项术前、术中和术后决策可能对术后肠道功能产生显著影响。这些因素包括手术切除范围、手术入路、吻合重建方式的选择以及粪便转流术的应用。本文综述了关于外科决策如何影响术后肠道功能的现有证据。
