The Longtan Modification: An Effective and Economical Surgical Innovation for Parastomal Hernia Post-Intraperitoneal Sigmoidostomy.

PURPOSE: This study was designed to introduce a new surgical innovation, referred to as the "Longtan modification," for cases with parastomal hernia (PSH) following intraperitoneal sigmoidostomy, and to assess the safety and feasibility of this procedure.

METHODS

Between January 2013 and June 2016, a total of 26 consecutive cases with PSH successfully underwent this procedure. The patient demographics, surgical outcomes, stoma-related complications, and the stoma function were collected and analyzed.

RESULTS

Mean diameter of the hernia ring was 7.6 cm, mean operation time was 94.2 minutes, and mean intraoperative blood loss was 18.0 mL. The mean period of postoperative hospitalization was 4.4 days while the mean hospitalization cost was only $3,750 USD. There were no severe complications such as postoperative hemorrhage, ischemic necrosis, peritoneal infection, or intestinal obstruction, although one case suffered from postoperative infection at the site of incision. None of the cases had a recurrence of PSH during the follow-up period. In addition, the stoma functioned efficiently and appropriately following the Longtan modification.

CONCLUSION

Overall, the Longtan modification appears to be an effective and economical surgical innovation for cases with PSH following intraperitoneal sigmoidostomy.
