Efficacy of innovative polyglycolic acid sheet device delivery station system: a randomized prospective study.

ABSTRACT:

Background

Although there have been several reports of treating large post-endoscopic submucosal dissection (ESD) ulcers by covering them with a polyglycolic acid sheet (PGAs), this approach presents problems regarding PGAs delivery. This study assessed the usefulness of a device delivery station system (DDSS) to evaluate the appropriate and rapid PGAs coating method with DDSS.

Methods

Thirty-nine of 41 patients who were diagnosed with early gastric cancer over 20 mm in diameter and pathologically diagnosed with well-differentiated adenocarcinoma were randomly allocated to the following two groups according to delivery method: the conventional PGAs delivery group (C group) (n = 19) and the new DDSS group (DDSS group) (n = 20). The primary outcome was the coating area per minute in the C group and DDSS group (cm²/min).

Results

There were significant differences in the coating time (min), with values of 34.1 (15.0-60.7) vs. 16.85 (11.5-27.2) min for the C group and DDSS group, respectively (p = 0.001). There was also a significant difference in coating area per minute, with values of 0.261 (0.02-1.00) and 0.96 (0.173-2.06) cm²/min for the C group and DDSS group, respectively (p = 0.001). There were four cases of post-ESD bleeding (1-7 days after ESD) in the C group compared with 0 in the DDSS group, which represented a significant difference (p = 0.030).

Conclusions

The DDSS was very useful for rapidly delivering and tightly attaching a PGAs to control post-ESD bleeding.

Project description:Papillary thyroid cancer (PTC) is the most common type of thyroid cancer. Surgery for PTC involves resection of the thyroid gland and central lymph node dissection. Central lymph node dissection is associated with an increased amount of fluid from the dissection area and chyle leakage due to thoracic duct injury. There are few studies that deal with reducing fluid drainage and preventing chyle leakage after thyroid surgery with central lymph node dissection. A polyglycolic acid mesh sheet (Neoveil™) has been demonstrated to prevent postoperative fluid leakage in other surgeries. This study aims to evaluate whether a polyglycolic acid mesh sheet can reduce postoperative drainage and chyle leakage in papillary thyroid cancer surgery, and this study was designed as a prospective, open-label, randomized controlled trial in a single university hospital. The patients were randomly assigned to having only fibrin glue used in the central node dissection area (control group) or to having a polyglycolic acid mesh sheet applied after fibrin glue (treatment group). A total of 330 patients were enrolled, of which 5 patients were excluded. A total of 161 patients were included in the treatment group, and 164 patients were included in the control group. The primary outcome was the drainage amount from the Jackson-Pratt drain, and the secondary outcome was the triglyceride level in the drained fluid on the 1st and 2nd postoperative days. The drainage amount was significantly lower in the treatment group on the 2nd postoperative day (60.9 ± 34.9 mL vs. 72.3 ± 38.0 mL, p = 0.005). The sum of drainage amount during the whole postoperative days (1st and 2nd days) was also significantly lower in the treatment group (142.7 ± 71.0 mL vs. 162.5 ± 71.5 mL, p = 0.013). The postoperative triglyceride levels were lower in the treatment group but were not statistically significant (92.1 ± 60.1 mg/dL vs. 81.3 ± 58.7 mg/dL on postoperative day 1, p = 0.104 and 67.6 ± 99.2 mg/dL vs. 53.6 ± 80.4 mg/dL on postoperative day 2, p = 0.162). No adverse effects were observed in the treatment groups during the postoperative 9-month follow-up. Our study suggests that polyglycolic acid mesh sheets can be safely applied to reduce postoperative drainage amount in thyroidectomy patients who need lymph node dissection.

Project description:Background:Uniportal video-assisted thoracoscopic surgery (VATS) for primary spontaneous pneumothorax (PSP) has demonstrated acceptable surgical outcomes while being less invasive than other surgical techniques. Fibrin glue-covered absorbable mesh has been applied to reinforce resected regions to prevent recurrence. We aimed to evaluate the outcomes of this technique without pleural abrasion in uniportal VATS for PSP. Methods:Between July 2012 and May 2017, 54 consecutive patients with PSP underwent uniportal VATS by a combination technique using a polyglycolic acid (PGA) sheet and fibrin glue without mechanical pleural abrasion. A bilateral approach was performed in five additional patients; thus, postoperative surgical outcomes of a total of 59 cases were analyzed. For subgroup analysis, we first divided the patients into a group of PGA sheet coverage, followed by additional fibrin glue application (n=36, Group A) and a group of fibrin glue injection prior to PGA sheet coverage (n=23, Group B). We reviewed the data and compared surgical outcomes to evaluate the efficacy of the application techniques. Results:There was a total 59 cases (43 males) with a median age of 18.0 years (range, 12-50 years). Demographic data revealed no differences between the two groups. There was no significant difference in operation time (41.8±10.1 vs. 41.3±8.8 minutes, P=0.821), length of hospital stay (4.1±1.3 vs. 3.8±1.1 days, P=0.411), or chest tube in-dwelling time (2.6±0.9 vs. 2.2±0.7 days, P=0.078) in the additional glue application and glue injection groups. Recurrence rates revealed no significant difference [2/36 (5.5%) vs. 1/23 (4.3%), P=0.837] between the two groups. There were neither conversions to multi-port VATS nor perioperative complications during a median follow-up period of 21.5 months. Conclusions:The combination method of the absorbable PGA sheet with fibrin glue established satisfactory outcomes without increasing morbidities, regardless of application technique. This simple technique is an effective procedure that does not require mechanical pleural abrasion or pleurodesis to prevent postoperative recurrences when conducting uniportal VATS for PSP.
