Abstract:
Objective:To primarily investigate the application value of glasses-free three-dimensional (3D) laparoscopy system in laparoscopic radical resection of gastrointestinal malignant tumors.Methods:The retrospective cohort study was conducted. The clinical data of 165 patients with gastrointestinal malignant tumors who were admitted to the Ruijin Hospital of Shanghai Jiaotong University School of Medicine between October 2018 and May 2019 were collected. There were 99 males and 66 females, aged from 28 to 86 years, with a median age of 63 years. There were 68 of 165 patients with gastric cancer and 97 with colorectal cancer. Sixteen patients with gastric cancer who underwent laparoscopic radical gastrectomy using the glasses-free 3D laparoscopy system were divided into glasses-free 3D gastric cancer group, and 52 patients with gastric cancer who underwent laparoscopic radical gastrectomy using the polarized glasses 3D laparoscopy system were divided into polarized glasses 3D gastric cancer group. Nineteen patients with colorectal cancer who underwent laparoscopic radical colectomy or proctectomy using the glasses-free 3D laparoscopy system were divided into glasses-free 3D colorectal cancer group, and 78 patients with colorectal cancer who underwent laparoscopic radical colectomy or proctectomy using the polarized glasses 3D laparoscopy system were divided into polarized glasses 3D colorectal cancer group. Observation indicators: (1) operative situations of patients with gastric cancer; (2) postoperative recovery of patients with gastric cancer; (3) postoperative pathological examination results of patients with gastric cancer; (4) operative situations of patients with colorectal cancer; (5) postoperative recovery of patients with colorectal cancer; (6) postoperative pathological examination results of patients with colorectal cancer; (7) follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect complications and survival of patients up to the postoperative 30th day. Measurement data with skewed distribution were represented as M ( P25, P75) or M (range), and comparison between groups was analyzed by the Mann-Whitney U test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results:(1) Operative situations of patients with gastric cancer: all the 68 gastric cancer patients received successfully laparoscopic radical gastrectomy, without intraoperative complication or conversion to laparotomy. Cases with distal gastrectomy or total gastrectomy(surgical methods) , operation time, volume of intraoperative blood loss were 11, 5, 195 minutes(169 minutes, 214 minutes), 20 mL (10 mL, 90 mL) in patients of the glasses-free 3D gastric cancer group, and 31, 21, 196 minutes(173 minutes, 222 minutes), 40 mL(20 mL, 100 mL) in patients of the polarized glasses 3D gastric cancer group, with no significant difference between the two groups ( χ2=0.432, Z=-0.362, -1.065, P>0.05). (2) Postoperative recovery of patients with gastric cancer: the time to first flatus, time to initial semi-fluid diet intake, duration of postoperative hospital stay were 2 days(2 days, 3 days), 6 days(5 days, 7 days), 10 days(9 days, 14 days) in patients of the glasses-free 3D gastric cancer group, and 2 days(2 days, 3 days), 6 days(5 days, 6 days), 11 days(9 days, 14 days) in patients of the polarized glasses 3D gastric cancer group, with no significant difference between the two groups ( Z=-0.163, -1.870, -0.570, P>0.05). The postoperative complication incidence of the glasses-free 3D gastric cancer group was 12.5%(2/16), including 1 case with duodenal stump fistula, 1 case with anastomotic bleeding. The postoperative complication incidence of the polarized glasses 3D gastric cancer group was 17.3%(9/52), including 2 cases with duodenal stump fistula, 2 cases with delayed gastric emptying, 1 case with pulmonary infection, 1 case with abdominal bleeding, 1 case with anastomotic leakage, 1 case with chylous fistula, 1 case with intestinal obstruction. All the patients with complications were cured after symptomatic supportive treatment. There was no significant difference in the complication incidence between the two groups ( χ2=0.209, P>0.05). (3) Postoperative pathological examination results of patients with gastric cancer: the tumor diameter, cases in stage T1, T2, T3, T4 (tumor T staging), cases with vascular invasion, cases with nerve invasion, cases with tumor nodule, cases in stage N0, N1, N2, N3 (tumor N staging), the number of positive lymph node, the number of lymph node dissected, cases with qualified lymph node dissected, cases in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ (TNM clinical staging) were 3.0 cm(2.0 cm, 5.0 cm), 5, 3, 1, 7, 8, 5, 2, 3, 2, 4, 7, 6(1, 15), 28(22, 43), 15, 4, 3, 9, 0 in patients of the glasses-free 3D gastric cancer group, and 3.5 cm(2.0 cm, 6.0 cm), 13, 10, 4, 25, 19, 23, 2, 26, 6, 7, 13, 1(0, 7), 29(21, 39), 43, 21, 10, 20, 1 in patients of the polarized glasses 3D gastric cancer group. There was no significant difference in the tumor diameter, tumor T staging, cases with vascular invasion, cases with nerve invasion, cases with tumor nodule, the number of lymph node dissected, cases with qualified lymph node dissected, TNM clinical staging between the two groups ( Z=-0.570, -0.434, χ2 =0.926, 0.851, 1.655, Z=-0.579, χ2=1.193, Z=-1.134, P>0.05). There were significant differences in the tumor N staging and the number of positive lymph node between the two groups ( Z=-2.167, -2.283, P<0.05). (4) Operative situations of patients with colorectal cancer: all the 97 colorectal cancer patients received successfully laparoscopic radical colectomy or proctectomy, without intraoperative complications or conversion to laparotomy. Cases with radical colectomy or proctectomy (surgical methods), operation time, volume of intraoperative blood loss were 7, 12, 132 minutes(97 minutes, 156 minutes), 20 mL(10 mL, 50 mL) in patients of the glasses-free 3D colorectal cancer group, and 40, 38, 124 minutes(110 minutes, 159 minutes), 25 mL(15 mL, 65 mL) in patients of the polarized glasses 3D colorectal cancer group, with no significant difference between the two groups ( χ2 =1.276, Z=-0.141, -0.863, P>0.05). (5) Postoperative recovery of patients with colorectal cancer: the time to first flatus, time to initial semi-fluid diet intake, duration of postoperative hospital stay were 2 days(1 days, 3 days), 5 days(5 days, 6 days), 8 days(7 days, 10 days) in patients of the glasses-free 3D colorectal cancer group, and 2 days(1 days, 3 days), 5 days(4 days, 6 days), 8 days(6 days, 10 days) in patients of the polarized glasses 3D colorectal cancer group, with no significant difference between the two groups ( Z=-0.678, -1.751, -1.674, P>0.05). The complication incidence of the glasses-free 3D colorectal cancer group was 15.8%(3/19), including 1 case with anastomotic leakage after low anterior proctectomy, 1 case with incision infection, 1 case with urinary tract infection. The complication incidence of the polarized glasses 3D colorectal cancer group was 14.1%(11/78), including 3 cases with anastomotic leakage after low anterior proctectomy, 2 cases with intestinal obstruction, 2 cases with urinary tract infection, 2 cases with incision infection, 1 case with anastomotic bleeding, 1 case with pulmonary infection. One of the 3 cases with anastomotic leakage after low anterior proctectomy in the polarized glasses 3D colorectal cancer group was cured after remedial terminal ileostomy. The other patients with complications were cured after symptomatic supportive treatment. There was no significant difference in the complication incidence between the two groups ( χ2=0.035, P>0.05). (6) Postoperative pathological examination results of patients with colorectal cancer: the tumor diameter, cases in stage T1, T2, T3, T4 (tumor T staging), cases with vascular invasion, cases with nerve invasion, cases with tumor nodule, cases in stage N0, N1-N2 (tumor N staging), the number of positive lymph node, the number of lymph node dissected, cases with qualified lymph node dissected, cases in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ (TNM clinical staging) were 5.0 cm(3.0 cm, 6.0 cm), 3, 2, 7, 7, 3, 2, 1, 8, 11, 0(0, 4), 17(14, 23), 18, 2, 3, 12, 2 in patients of the glasses-free 3D colorectal cancer group, and 4.0 cm(3.0 cm, 5.0 cm), 7, 16, 43, 12, 14, 12, 7, 46, 32, 0(0, 1), 16(13, 19), 74, 14, 17, 40, 7 in patients of the polarized glasses 3D colorectal cancer group, with no significant difference between the two groups ( Z=-0.768, -1.135, χ2 =0.049, 0.292, 0.278, 1.762, Z=-0.694, -1.349, χ2=0.001, Z=-1.011, P>0.05). (7) Follow-up: 165 patients received follow-up, with out short-term reoperation or postoperative death in the postoperative 30 days. Conclusion:There is no significant difference in the efficacy between glasses-free 3D laparoscopic surgery and polarized glasses 3D laparoscopic surgery for radical resection of gastrointestinal malignant tumors, of which the clinical value requires further study.
