Abstract PDF

Few radiation-induced bowel perforations have been reported to date. Furthermore, perforation after ileal restoration in asymptomatic patients is rare. We report the case of a 61-year-old man who was administered preoperative chemoradiotherapy for advanced rectal cancer. The patient underwent ultra-low anterior resection with ileal diversion, followed by ileal restoration. Perforation was detected 9 days after restoration, and he underwent a right hemicolectomy. The histologic evaluation indicated ileal perforation caused by acute radiation enteritis.

Purpose
We investigated the sensitivity of various evaluating modalities in predicting a pathologic complete response (pCR) after preoperative chemoradiation therapy (PCRT) for locally advanced rectal cancer (LARC).
Methods
From a population of 2,247 LARC patients who underwent PCRT followed by surgery at Asan Medical Center, Seoul, Korea from January 2007 to June 2016, we retrospectively analyzed 313 patients (14.1%) who showed a pCR after surgery. Transrectal ultrasound (TRUS), high-resolution magnetic resonance imaging (MRI), abdominopelvic computed tomography (AP-CT), and endoscopy were performed within 2 weeks prior to surgery.
Results
Of the 313 patients analyzed, 256 (81.8%) had a pCR after radical surgery and 57 (18.2%) showed total regression after local excision. Preoperative TRUS, MRI, and AP-CT were performed in 283, 305, and 139 patients, respectively. Among these 3 groups, a prediction of a pCR of the primary tumor was made in 41 (14.5%), 51 (16.7%), and 27 patients (19.4%), respectively, before surgery. A prediction of a clinical N0 stage was made in 204 patients (88.3%) using TRUS, 130 (52.2%) using MRI, and 78 (65.5%) using AP-CT. Of the 211 patients who underwent endoscopy, 87 (41.2%) had a mention of clinical CR in their records. A prediction of a pathologic CR was made for 124 patients (39.6%) through at least one diagnostic modality.
Conclusion
The various evaluation methods for predicting a pCR after PCRT show a predictive sensitivity of 0.15–0.41 for primary tumors and 0.52–0.88 for lymph nodes. Endoscopy is a relatively superior modality for predicting the pCR of the primary tumor of LARC patients.

Purpose

This study evaluated the efficacy of a water-soluble contrast enema (WCE) in predicting anastomotic healing after a low anterior resection (LAR).

Methods

Between January 2000 and March 2012, 682 consecutive patients underwent a LAR or an ultra-low anterior resection (uLAR) and were followed up for leakage. Clinical leakage was established by using physical and laboratory findings. Radiologic leakage was identified by using retrograde WCE imaging. Abnormal radiologic features on WCE were categorized into four types based on morphology: namely, dendritic, horny, saccular, and serpentine.

Results

Of the 126 patients who received a concurrent diverting stoma, only two (1.6%) suffered clinical leakage due to pelvic abscess. However, 37 patients (6.7%) in the other group suffered clinical leakage following fecal diversion (P = 0.027). Among the 163 patients who received a fecal diversion, 20 showed radiologic leakage on the first WCE (eight with and 12 without a concurrent diversion); 16 had abnormal features continuously until the final WCE while four patients healed spontaneously. Eleven of the 16 patients (69%), by their surgeon's decision, underwent a stoma restoration based on clinical findings (2/3 dendritic, 3/4 horny, 5/7 saccular, 1/2 serpentine). After stoma reversal, only 2 of the 11 (19%) complained of complications related to the rectal anastomosis.

Conclusion

WCE is helpful for detecting radiologic leakage before stoma restoration, especially in patients suffering clinical leakage after an uLAR. However, surgeons appear to opt for stoma restoration despite the persistent existence of radiologic leakage in cases with particular features on the WCE.

Abstract: Purpose
The decision for treatment after neoadjuvant chemoradiotherapy (nCRT) in rectal cancer is intricately linked to tumor response and clinical parameters. This study was designed to elucidate determinants influencing treatment decisions for good responders to nCRT, while concurrently evaluating the ramifications of modifications in magnetic resonance imaging (MRI) tumor response evaluation protocols.
Methods
A survey was constructed with 5 cases of good responder after nCRT based on the magnetic resonance–based tumor regression grade (mrTRG) criteria. A total of 35 colorectal surgeons in Korea participated in the survey via email, and they were introduced to 2 discrete MRI-based tumor response evaluation methodologies: the conventional mrTRG and an emergent complete response (CR)/non-CR classification system. Surgeons were directed to select between total mesorectal excision, local excision, or a watch and wait strategy.
Results
Treatment decisions varied significantly (P<0.01), as gradually more clinical information was provided with mrTRG. The paradigm shift from mrTRG to CR/non-CR evaluation criterion instigated the highest alteration in decision (P<0.01). Even comparing with other sets of information, decision change with different tumor response assessment (i.e., mrTRG vs. CR/non-CR) was statistically significant (P<0.01). Three particular cases consistently displayed a declining predilection for total mesorectal excision, favoring a more pronounced inclination towards watch and wait strategy or local excision. Nonetheless, the magnitude of these decisional shifts oscillated depending on the specific endoscopic imagery present.
Conclusion
Our current findings underscore the significant role of tumor response assessment methods in shaping treatment decisions for rectal cancer patients who respond well to nCRT. This highlights the need for clear and accurate tools to interpret MRI results.
