Laparoscopic Welti's Maneuver: A Single-Center Experience.

Left hemicolectomy is the standard surgical operation for a variety of colonic diseases, both benign and malignant. When colonic resection is extended, relocation of the small bowel loops can be difficult. Several techniques have been described to reposition the small intestine. Welti's technique consists in the passage of the entire small bowel to the left side of the abdomen, below the descending colon that is positioned on the right side. We retrospectively evaluated 23 patients who underwent extended left hemicolectomy and reconstruction according to the Welti's technique at our hospital. We assessed the recovery of intestinal function and the length of hospital stay; in the mid-term follow-up we searched for episodes of acute or chronic intestinal obstruction. Median operative time was 215 minutes; median resumption of gas and stool emission were, respectively, 3 days (interquartile range [IQR]: 2-6) and 4 days (IQR: 2-9) after surgery. Median hospital stay was 8 (IQR: 5-37) day. After a median follow-up of 15 months (IQR: 3-132) we did not observe any episode of acute or chronic bowel obstruction. Welti's technique is safe and does not cause a delay in resumption of bowel functions or a delayed hospital discharge; it is a useful technique that the colorectal surgeon can use when needed.
