Application of double circular suturing technique (DCST) in the repair of large abdominal wall defects after resection of abdominal wall tumor

BACKGROUND: The aim of this study was to investigate the clinical effects of repairing large defects using the double circular suturing technique (DCST) after resection of abdominal wall tumor. METHODS: The clinical data of 62 patients (25 men, 37 women; average age 41.7±22.4 years) who underwent DCST between October 2010 and November 2018 for the repair of large abdominal wall defects with anti-adhesion underlay mesh after resection of abdominal wall tumor were retrospectively analyzed. The maximum diameter of abdominal wall defect after resection of abdominal wall tumor was 10.4±5.6 cm. The course of disease was 1–341 months, and the average was 32.4 months. Operative time, postoperative hospitalization time, perioperative complications, tumor recurrence in situ, incidence of postoperative chronic pain, and hernia were recorded. RESULTS: All 62 operations were completed successfully. The operative time was 73.2±31.4 minutes, and the mean postoperative hospitalization time was 9.6 days (range, 2–20 days). In total, 54 patients were followed up postoperatively for a median 6.7 years (range, 0.9–9.0 years). Partial splitting of incisions occurred in 2 patients, fat liquefaction of incisions occurred in 3 patients, and chronic pain occurred in 4 patients. No tumor in situ recurrence, hernia, or other complications were found in any cases in the follow-up. Tumor metastasis occurred in 9 patients with 6 of these patients dying of tumour progression. CONCLUSIONS: With simple operations, short procedure time, few complications, low tumor recurrence rate, and low incidence of postoperative chronic pain, application of DCST in the repair of large abdominal wall defects is effective after resection of abdominal wall tumor.
