Prone Jack-Knife Transanal Minimally Invasive Surgery (tamis) is a feasible and safe approach for managing subepithelial rectal lesions, specifically anterior low rectal gastrointestinal stromal tumors (gist). This surgical technique, performed with the patient in the prone jack-knife position and using transanal access, provides excellent surgical…
A retrospective study investigated the impact of postoperative adjuvant chemotherapy (POAC) on outcomes in patients with colorectal cancer liver metastases (CRLM) undergoing simultaneous resection. After propensity score matching analysis, 478 patients were enrolled and assigned to POAC or non-POAC groups. The study found that POAC…
Researchers conducted a retrospective analysis of 238 women with defecatory disorders and found that age, vaginal delivery, and prior pelvic surgery were associated with increased grades of rectal intussusception. The study also revealed that obstructive defecation symptoms and dyssynergic defecation were common across the groups.…
In a large series of Crohn's disease patients, the Kono-S anastomosis demonstrated very low postoperative complication rates (1.5% anastomotic failure, 6.1% infection). Surgical recurrence occurred in 7.6% of cases, with perianal disease, urgent/emergent surgery, and postoperative steroid use associated with increased risk. The anastomosis showed…
A retrospective cohort study was conducted to assess the local recurrence and survival rates after transanal abdominal transanal radical proctosigmoidectomy for low rectal cancer treated with neoadjuvant chemoradiation therapy. The study included 255 patients and found that the procedure demonstrated excellent long-term locoregional control and…
Rectal cancer patients who underwent Hartmann's procedure were significantly older, had more comorbidities, and were more likely to have the procedure preoperatively due to comorbidities or oncological reasons. In 23% of cases, the decision to perform Hartmann's procedure was made intraoperatively, mainly due to anastomotic…
Patients' perspectives on colectomy for recurrent diverticulitis were explored through focus groups. A conceptual framework was developed to capture major themes identified in the qualitative data. The study found that the decision to pursue colectomy is highly preference sensitive, influenced by patients' beliefs about surgery,…
The field of coloproctology is witnessing a paradigm shift towards less invasive treatments due to remarkable advancements in medical care. This shift is particularly notable in gastroenterology, specifically in colorectal surgery. Both benign and malignant colorectal conditions are now being treated with more conservative and…
Researchers analyzed local recurrence and disease-free survival in patients treated with transanal total mesorectal excision (TaTME) for rectal cancer. The study included 279 patients treated at a high-volume tertiary center in Vancouver, Canada. The results showed that the local recurrence rate was 4.7%, and the…
A study investigated the utility of machine learning algorithms in predicting complications for patients undergoing colectomy for colonic neoplasia. The three machine learning models successfully identified patients who developed complications, with the neural network scoring highest in predicting anastomotic leak, prolonged length of stay, and…
