Modified laparoscopic combined with gastroscopic surgery for the gastric stromal tumors from the muscularis propria / 中华消化外科杂志

ABSTRACT

Objective To explore the clinical effects of laparoscopic combined with gastroscopic surgery for the gastric stromal tumors (GSTs) from the muscularis propria.Methods The clinical data of 25 patients with GSTs from the muscularis propria who were admitted to the Qianfoshan Hospital Affiliated to Shandong University between January 2011 and January 2014 were retrospectively analyzed.Patients received the general anaesthesia by endotracheal intubation.The pneumoperitoneum was done by an arc incision of 0.5 cm above margin of the umbilical cord and then laparoscopy was placed for exposing and gastroscopy was placed for confirming the location of the tumor.A laparoscope was placed in the cavity via the trocar at the navel,and the other two trocars penetrated both the abdominal and stomach walls.With gastroscopic monitoring,the operation was carried out in the gastric lumen using laparoscopic instruments and the tumor was resected.The tumor tissue was removed orally using a gastroscopic basket,and puncture holes and perforations were sutured using titanium clips.The proton pump inhibitor and antibiotics were used as the conventional therapy for 3 days,while adjuvant therapy with a usage of imatinib was applied to patients who were confirmed with the high-risk GSTs by pathological examination after tumors resection,and the other patients did not receive adjuvant therapy.Gastroscopic reexamination was done every 3 months within postoperative 1 year and then every 6 months after 1 year.Abdominal CT reexamination was done every 6 months within postoperative 1 year and then every 1 year after 1 year.The followup was done till December 2014.Results All the 25 patients received successfully modified laparoscopic combined with gastroscopic surgery without conversion to open surgery and postoperative complication.The operation time,volume of intraoperative blood loss,diameter of tumor,duration of postoperative abdominal pain and duration of hospital stay were (79 ± 4) minutes,(28 ± 3) mL,(2.6 ± 0.3) cm,(2.8 ± 0.3) days and (6.3 ± 0.3) days,respectively.GSTs were confirmed by postoperative pathological examination.The mitotic count was (3.3 ± 0.3) /50 HPF and reached R0 resection.Extremely low risk was detected in 3 patients,low risk in 19 patients,intermediate risk in 3 patients and no high risk was detected.Two of 3 patients with intermediate risk took the medicines following instructions without the adverse drug reaction,and 1 of 3 patients refused to take the medicines due to low income.All the patients were followed up for 12-36 months without the recurrence or metastasis of tumors.Conclusion Modified laparoscopic combined with gastroscopic surgery is feasible and effective for the treatment of gastric stromal tumors (GSTs) from the muscularis propria.
