Serosal and muscular layers incision and use of submucosal layers exfoliation technique in laparoscopic surgery for gastric gastrointestinal stromal tumors / 中华普通外科杂志

ABSTRACT

Objective To explore the feasibility and clinical efficacy of serosal muscular layers incision and submucosal layers exfoliation technique in laparoscopic surgery for gastric gastrointestinal stromal tumors(GIST).Methods 28 patients with gastric GIST underwent serosal muscular layers incision and submucosal layers exfoliation technique under laparoscopic surgery.Patients' clinicopathologic characteristics,operative outcomes,postoperative complications,and follow up results were analyzed retrospectively.Results Surgery was successfully completed in all patients,and no one was converted to open surgery.The average operation time was (66 ± 15) min,and the intra operative blood loss was (16 ± 10) ml,the time of passage of gas by anus after operation was (20 ± 10)h,the time starting liquid diet was (2.5 ± 1.6) d,and the length of postoperative hospital stay was (7 ± 3) d.One patient had delayed gastric emptying,one had incisional infection.All the specimen had complete pseudocapsule and negative margin.pathology was all gastric GIST.After a median 22 months followed up,no recurrence or metastasis were found.Conclusion Serosal muscular layers incision and submucosal layers exfoliation under laparoscopic surgery is a safe and feasible procedure for treating gastric GIST.
