Design: Randomised, three-arm, blinded superiority trial, single centre
Population: 320 adults having minimally invasive colorectal cancer resection
Primary outcome: QoR-15 score at 24 hours
Effect: TAP block +10.44 points (95% CI 3.06 to 17.83) vs analgesia alone

A single-centre, three-arm trial at a Japanese cancer centre randomised 320 adults having minimally invasive colorectal resection to IV patient-controlled analgesia alone, or with a surgeon-performed rectus sheath block, or with a laparoscopic bilateral dual TAP block. Patients and assessors were blinded.

Compared with analgesia alone, the TAP block raised the 24-hour Quality of Recovery-15 score by 10.4 points (95% CI 3.1 to 17.8). The rectus sheath block did not reach significance (5.5 points, −1.9 to 12.9). Both blocks delayed the first rescue analgesic from 3.3 hours to about a day. Total 48-hour fentanyl use and length of stay did not differ. No block-related complications occurred.

This is a cheap, fast addition that improved how patients felt the day after surgery. It did not shorten stay, so the gain is in comfort and recovery quality rather than throughput.

Add a laparoscopic bilateral dual TAP block to minimally invasive colorectal resections.
Agree the local anaesthetic plan with the anaesthetist so doses are not duplicated.
Do not expect shorter length of stay; the gain is recovery quality.
Audit QoR-15 or a similar score locally if introducing it.

Why it matters

It gives surgeons a block they can place themselves that measurably improves the first postoperative day.

The statistics, in plain English

A 10-point QoR-15 gain exceeds the roughly 6 to 8 points usually considered the minimal important difference, so it is clinically as well as statistically meaningful. The rectus sheath interval crossed zero, so its benefit is uncertain rather than disproven.
