Clinical Trial Summary

This study aims to compare the postoperative outcomes of low rectal cancer patients who underwent surgery with Natural Orifice Specimen Extraction (NOSE) versus traditional Pfannenstiel extraction.

Description:

Natural Orifice Specimen Extraction (NOSE) in colorectal surgery allows the extraction of the surgical specimen through the anal orifice. Several studies demonstrated improved postoperative pain, bowel movements, patient-reported cosmetic satisfaction, and psychological wellbeing after NOSE compared with traditional Pfannenstiel extraction. However, most of these studies focused on colon surgery. The aim of this retrospective propensity score matched study is to investigate the postoperative outcomes of NOSE in low rectal cancer surgery, classified according to the English National Low Rectal Cancer Development Programme (LOREC).

Primary	Surgical Site Infections (SSI)	Rate difference of 30-day Surgical Site Infections (SSI)- defined according to the definition of the Center for Disease Control and Prevention (CDC) [Ref]- between the study cohorts.	30 days after surgery
Secondary	Opioid rescue	Difference in the proportion of patients requiring opioid rescue during the hospitalization	From the date of surgery to the date of discharge
Secondary	Postoperative pain	The median difference of 72-hour patient-reported pain- measured on the Visual Rating Scale (VRS)	72 hours after surgery
Secondary	Postoperative ileus	Rate difference of 30-day postoperative functional ileus (define as the absence of bowel function for at least three days)	30 days after surgery
Secondary	Incisional hernia	The rate difference of six-month incisional hernia	6 months after surgery
Secondary	Overall postoperative complications	The rate difference of overall 30-day postoperative complications, classified according to the Clavien-Dindo scale [ranging from 0 (no complications) to 5 (complications leading to death)]	30 days after surgery
