Nephrectomy for Pediatric Renal Tumors: A Modified Surgical Approach to Minimize Post-operative Intestinal Obstruction.

The authors present a modified surgical technique during tumor nephrectomy in children with a conservative approach towards small bowel manipulation and cutting of the peritoneal reflections. We aimed to evaluate this modified surgical approach regarding the incidence of post-operative small bowel obstruction (SBO), and its technical utility.

The study includes all children with unilateral renal tumors who underwent radical nephrectomy and lymph nodes sampling at our tertiary center from 2010 to 2022. The modified technique was performed via the usual transverse incision. We cut the peritoneal reflections short of the cecum or short of the sigmoid colon. The colon is reflected over SB packing it, proceeding to nephrectomy and lymph nodes sampling. Data included demographics, clinical characteristics, treatment strategy, operative details, post-operative SBO, and overall outcomes.

The study included 890 patients with a median age of 3.2 years. The median tumor largest diameter was 13 cm (range: 9-18 cm). The modified surgical technique was adopted in 287 patients (32.3 %). Forty-three patients (43/890, 4.8 %) had post-operative SBO. Out of them, only 4 cases were operated on using the modified surgical technique (p-value<0.001). There were no significant differences between both techniques regarding timing of surgery, tumor rupture, lymph nodes sampling, and tumor size (p-value = 0.775, 0.328, 0.216, and 0.563, respectively).

The modified surgical approach is significantly correlated with lower incidence of post-operative SBO with no increased risk of tumor rupture or incomplete lymph nodes sampling. The timing of surgery or tumor characteristics had no significant impact on the technical utility of the modified surgical approach.

Level IV.
