RESUMO
BACKGROUND/AIM: The reported incidence of rectovaginal fistula is very low. Although some case reports have described surgical procedures, no systematic approach to the treatment of rectovaginal fistula according to diagnostic image and colonoscopy findings has been proposed. We present a comprehensive surgical strategy for rectovaginal fistula after colorectal anastomosis according to diagnostic image and colonoscopy findings. PATIENTS AND METHODS: This retrospective study included 11 patients who developed rectovaginal fistula after colorectal anastomosis. Rectovaginal fistula was classified into 4 types according to contrast enema images and colonoscopy findings, i.e., "Alone type", "Dead space type", "Anastomotic stricture type", and "Dead space and Anastomotic stricture type". The surgical strategies were "Diversion (Stoma)", "Percutaneous drainage", "Anastomotic stricture type", "Endoscopic balloon dilation", "Curettage of foreign bodies", "Simple full-thickness closure", "Split-thickness closure", "Pedicled flaps packing", and "Reanastomosis". The surgical strategy appropriate for each rectovaginal fistula type was investigated. RESULTS: Among "Alone type" cases, 5 (71.4%) healed with "only Diversion (Stoma)". "Alone type" cases (n=11) and all other cases (n=4) healed with "only Diversion (Stoma)" (n=5) or any other method (n=6) (p=0.022). CONCLUSION: For treatment of rectovaginal fistula after colorectal anastomosis, less invasive treatment approaches should be attempted first.

BACKGROUND: We clarified the effects of perioperative enteral supplementation with glutamine, fiber, and oligosaccharide (GFO) after an esophagectomy on preventing surgical stress. METHODS: Of 326 patients with esophageal cancer, 189 received GFO administration (GFO group) and 137 did not (control group). The propensity score matching method was used to identify 89 well-balanced pairs of patients to compare postoperative laboratory parameters and clinical and postoperative outcomes. RESULTS: The duration of the systemic inflammatory response syndrome (SIRS) was significantly shorter in the GFO group compared to the control group (p = 0.002). Moreover, the lymphocyte/neutrophil ratio (L/N ratio) had significantly recovered in the GFO group on postoperative day-3, and the CRP value was significantly lower in the GFO group than that in the control group on postoperative day-2. CONCLUSIONS: Perioperative use of enteral supplementation with glutamine, fiber, and oligosaccharide likely contributes to a reduction in early surgical stress after an esophagectomy. These beneficial effects can bring about early recovery from postoperative immunosuppressive conditions after radical esophagectomy.
