Existing inconsistencies in the practice of bowel technique prompted a study to validate this operating room procedure. Minimal reference to intra-operative bowel technique was found in the literature. Needle drivers and tissue forceps utilized to anastomose large bowel were cultured, and the results were analysed. Needle drivers and tissue forceps used to anastomose small bowel were also cultured and used as a control group. Only elective bowel surgery cases were included in the study. The study demonstrated that there was consistent contamination to those instruments used for bowel anastomosis, with significantly greater contamination for large bowel resections. These results indicate that isolating those instruments and equipment which come into direct contact with the bowel lumen is a perioperative practice which will reduce the surgical patient's risk of postoperative wound infection.
目前肠道手术操作中存在的不一致性促使开展一项研究以验证这种手术室操作程序。文献中对术中肠道手术操作的提及极少。对用于大肠吻合的持针器和组织镊进行了培养，并对结果进行了分析。用于小肠吻合的持针器和组织镊也进行了培养并作为对照组。该研究仅纳入择期肠道手术病例。研究表明，用于肠道吻合的器械存在持续污染，大肠切除术的污染明显更严重。这些结果表明，隔离那些直接接触肠腔的器械和设备是一种围手术期操作，这将降低手术患者术后伤口感染的风险。
