Circular Stapler-Assisted Extraperitoneal Colostomy in Laparoscopic Abdominoperineal Resection: a Single Surgeon Experience

Extraperitoneal colostomy after laparoscopic abdominoperineal resection using a cannula for tunnel creation through a trocar port

BACKGROUND

Extraperitoneal colostomy (EPC) after laparoscopic abdominoperineal resection (APR) remains a challenge for surgeons. This study aims to summarize our laparoscopic EPC method and assess its effects versus a transperitoneal colostomy (TPC) for patients with rectal tumors.

METHODS

A total of 133 patients with rectal cancer treated with laparoscopic APR between May 2009 and May 2020 were retrospectively reviewed. The clinical data, including demographics, comorbidities, tumor stage, colostomy duration, and complications were compared between the EPC group and the TPC group.

RESULTS

The EPC group included 83 patients whose extraperitoneal tunnels were created using a cannula through a trocar port, and the TPC group included 50 patients whose stomata were formed traditionally. There were no differences in colostomy time [(23.1 ± 6) min vs. (21.4 ± 4) min, P = 0.078], number of parastomal dermatitis patients (5 vs. 2, P = 0.916), or number of stomal stenoses (1 vs. 1, P = 0.715) between the EPC and TPC groups. No cases of parastomal hernia developed in the EPC group, whereas 4 patients were diagnosed with a parastomal hernia; the difference between the two groups was statistically significant (P = 0.036).

CONCLUSIONS

Laparoscopic EPC have a lower incidence of parastomal hernia than TPC. It is easy and inexpensive to create an extraperitoneal tunnel using a cannula through a trocar port.

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.
