Watch and Wait for rectal cancer in inflammatory bowel disease

Colorectal cancer is currently the third most frequently diagnosed type of cancer and the second cause of cancer death in the western world. Inflammatory bowel disease patients are 2-6 times more likely to develop CRC than the general population. Patients with CRC arising through Inflammatory Bowel Disease have an indication for surgery. However, in patients without Inflammatory Bowel Disease, the use of organ (rectum) preservation strategies after neoadjuvant treatment is on the rise, which means that patients are able to keep the organ without the need for complete excision, either by treatment with radiotherapy and chemotherapy, or in combination with endoscopic or surgical techniques that allow local excision without the need for resection of the entire organ. The patient management approach known as the Watch and Wait programme was first introduced in 2004 by a team from São Paulo, Brazil. This approach suggested that patients who had an excellent or complete clinical response after neoadjuvant treatment could defer surgery and instead undergo Watch and Wait. This organ preservation technique became popular because it allowed patients to avoid the complications associated with major surgery while achieving similar oncological outcomes to those who underwent both neoadjuvant therapy and radical surgery. Following completion of neoadjuvant treatment, a decision to defer surgery is made based on whether a clinical Complete Response can be achieved, which means there is no evidence of tumour in clinical and radiological examination. The International Watch and Wait Database has published long-term oncological outcomes for patients treated with this strategy, and more patients are showing interest in this treatment option. However, it is important to note that up to 1/3 of patients selected for Watch and Wait may eventually require surgery for local regrowth (also known as 'deferred definitive surgery') at any time during follow-up after an initial 'apparent' clinical Complete Response. Compliance with a strict surveillance protocol ensures early detection of regrowth, which is usually amenable to R0 surgery and provides excellent long-term local disease control. Nonetheless, it is crucial to assess the perioperative consequences of having surgery for regrowth later and whether there are any negative effects from deferring surgery. Currently, the Watch and Wait strategy is recommended in the NCCN guidelines for clinical complete responders and only in specialised multidisciplinary centres.There is no case in the literature that portrays the use of the Watch and Wait programme for patients with inflammatory bowel disease and rectal cancer.The authors intend to present a case that demonstrates the difficulties in the assessment of patients with inflammatory bowel disease, the risks of using radiotherapy in this patients and the challenges of surveillance for patients with colorectal cancer and inflammatory bowel disease.

Laparoscopic colorectal surgery and discharge within 24 h-who is at risk for readmission?

AIM

The aim was to describe risk factors for hospital readmission in patients undergoing laparoscopic colorectal procedures and being discharged in ≤24 h.

METHOD

All consecutive patients undergoing minimally invasive colorectal surgery between 2010 and 2019 from a single institution were retrospectively reviewed. All patients were included in an enhanced recovery programme. Patients who met criteria for hospital discharge were compared according to the need for readmission in a 45-day follow-up.

RESULTS

In all, 664 patients underwent minimally invasive colorectal surgery during the study period and 237 (35.7%) were discharged in ≤24 h. Readmission was required in 16 (6.8%) patients discharged in ≤24 h and no postoperative mortality was observed in this group. Patients discharged in ≤24 h were more likely to have benign disease (P < 0.001), fewer associated procedures (P < 0.025) and intracorporeal anastomoses (P < 0.001). The type of surgical procedure (abdominoperineal resection), low rectal tumour, malignant disease, older age and longer operating time were associated with readmission. Age (OR 1.06; P = 0.037), malignant disease (OR 4.39; P = 0.05) and operating time (OR 1.03; P < 0.001) were identified as independent predictive factors for readmission amongst patients being discharged in ≤24 h.

CONCLUSION

Highly selected patients undergoing minimally invasive procedures in colorectal surgery may be safely discharged within 24 h following the procedure. High-risk features for readmission include older age, malignant disease and longer operating time.
