Tailored Surgical Algorithm Improves Symptoms in Severe Refractory Intestinal Dysmotility

A single-center retrospective study evaluating a dynamic, tailored surgical algorithm for severe refractory intestinal dysmotility disorders demonstrated significant postoperative symptom improvements in pain, bloating, and bacterial overgrowth. Researchers evaluated outcomes across 55 patients treated between 2017 and 2024 at the Shiraz Transplant Center at Abu Ali Sina Hospital, addressing severe clinical presentations such as chronic intestinal pseudo-obstruction and colonic dyssynergia.

Surgical management for severe, refractory intestinal dysmotility disorders remains a complex clinical challenge. While intestinal transplantation serves as a high-risk last resort, less invasive interventions—specifically total colectomy and the Trifecta procedure, which combines subtotal colectomy, pyloroplasty, and ileostomy—offer potential palliative benefits. However, direct comparative evidence guiding the selection and staging of these interventions has historically remained limited.

To address this clinical challenge, the investigators implemented a dynamic surgical pathway tailored to specific underlying diagnoses and diagnostic certainty. Under this algorithm, patients with confirmed chronic intestinal pseudo-obstruction underwent the Trifecta procedure, whereas individuals diagnosed with colonic dyssynergia underwent total colectomy. For patients presenting with diagnostic uncertainty, the Trifecta procedure was employed initially, allowing clinicians to utilize postoperative ileostomy output as a guide for further reassessment, while refractory cases were evaluated for intestinal transplantation.

Across the total cohort of 55 patients evaluated in the study, distribution across surgical modalities reflected the tiered decision-making framework. A total of 12 patients, representing 21.8 percent of the cohort, received the Trifecta procedure, while 16 patients, or 29.1 percent, underwent total colectomy. The remaining 27 patients, accounting for 49.1 percent of the study population, underwent intestinal transplantation as refractory candidates within the pathway.

Postoperative clinical outcomes were evaluated by comparing pre- and postoperative symptom manifestations using the Exact McNemar test. The primary endpoint assessed postoperative symptom status, classified as symptom-free, symptom reduction, or mortality at the last recorded follow-up. The statistical analysis revealed significant improvements in abdominal pain, abdominal bloating, and bacterial overgrowth, with each measure achieving a significance level of p < 0.001. In contrast, defecation difficulties showed no statistically significant change following intervention, yielding an observed p-value of 0.262.

Overall mortality was documented in 12 of the 55 patients, establishing a total mortality rate of 21.8 percent across the entire cohort. Mortality varied substantially depending on the surgical procedure performed: 11 of the 27 intestinal transplant recipients (40.7 percent) died, and 1 of the 16 total colectomy patients (6.3 percent) died, whereas no deaths occurred among the 12 patients who underwent the Trifecta procedure. Exploratory analyses indicated that postoperative outcomes were significantly associated with preoperative body mass index (p = 0.042) and baseline clinical status (p < 0.001), indicating that higher body mass index and better baseline clinical conditions correlated with more favorable postoperative results.

The authors concluded that employing a tailored surgical algorithm, with the Trifecta procedure functioning concurrently as a palliative treatment and an intermediate diagnostic tool, suggested symptom relief in this patient series. Nevertheless, the study authors emphasized notable methodological limitations, including the retrospective extraction of symptom data from clinical records and the absence of standardized complication records, nutritional data, and validated patient-reported outcome measures or symptom scores. Consequently, the research team highlighted the necessity of prospective validation to substantiate these findings.
