RESUMO
Objective:To compare the short-term efficacy of Billroth Ⅱ+Braun anasto-mosis versus Roux-en-Y anastomosis in totally three-dimensional (3D) laparoscopic distal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 140 patients with gastric cancer who were admitted to the First Medical Center of Chinese PLA General Hospital from January 2016 to January 2020 were collected. There were 105 males and 35 females, aged from 23 to 84 years, with a median age of 55 years. Of the 140 patients, 54 patients undergoing totally 3D laparoscopic distal gastrectomy with Billroth Ⅱ+Braun anastomosis were allocated into Billroth Ⅱ+Braun group, and 86 patients undergoing totally 3D laparoscopic distal gastrectomy with Roux-en-Y anastomosis were allocated into Roux-en-Y group, respectively. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect remnant gastritis and its severity, bile reflux, reflux esophagitis in the postoperative 3 months up to April 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the Mann-Whitney U test. Results:(1) Surgical situations: 140 patients underwent totally 3D laparoscopic distal gastrectomy. The operation time, cases with volume of intraoperative blood loss <50 mL, 50 to 200 mL or >200 mL, the number of lymph node dissected were (233±39)minutes,15, 35, 4, 30±13 for the Billroth Ⅱ +Braun group , respectively, versus (240±52)minutes,25, 51, 10, 27±10 for the Roux-en-Y group, showing no significant difference between the two groups ( t=0.856， χ2=0.774， t=1.518， P>0.05). (2) Postoperative situations: cases with drainage tube, time to postoperative first flatus, cases with postoperative grade Ⅱ, Ⅲ, Ⅳ, Ⅴ complications, cases with postoperative complications, cases with postoperative severe complications, duration of postoperative hospital stay, surgery cost and total hospitalization cost of the Billroth Ⅱ+Braun group were 38, (3.5±0.8)days,4, 1, 0, 0, 5, 1, (9.0±5.0)days, (3.8±1.2)×10 4 yuan and (9.7±2.1)×10 4 yuan, respectively. The above indicators of the Roux-en-Y group were 59, (3.7±1.0)days, 9, 1, 0, 1, 11, 2, (9.0±4.0)days, (4.3±1.0)×10 4 yuan and (9.2±2.1)×10 4 yuan, respectively. There was a significant difference in the surgery cost between the two groups ( t=2.453, P<0.05), while there was no significant difference in cases with drainage tube, time to postoperative first flatus, cases with postoperative grade Ⅱ, Ⅲ, Ⅳ, Ⅴ complications, cases with postoperative complications, duration of postoperative hospital stay or total hospitalization cost between the two groups ( χ2=0.049, t=?1.339, Z=0.000, χ2=0.409, t=0.197, 1.383, P>0.05). There was also no significant difference in cases with postoperative severe complications between the two groups ( P>0.05).(3) Follow-up: 134 of 140 patients received the follow-up, including 52 cases in the Billroth Ⅱ+Braun group and 82 cases in the Roux-en-Y group. Results of follow-up within postoperative 3 months showed that the incidence rates of remnant gastritis, bile reflux, reflux esophagitis were 61.5%(32/52), 38.5%(20/52), 26.9%(14/52) for the Billroth Ⅱ+Braun group, respectively, versus 41.5%(34/82), 22.0%(18/82), 12.2%(10/82) for the Roux-en-Y group, showing significant differences between the two groups ( χ2=5.131, 4.270, 4.695, P<0.05). Cases with grade 0,Ⅰ,Ⅱ, Ⅲ, Ⅳ residual food were 42, 3, 5, 2,0 for the Billroth Ⅱ+Braun group, versus 67, 9, 1, 5,0 for the Roux-en-Y group, showing no significant difference between the two groups ( Z=?0.156, P>0.05). Cases with minimal lesion, grade A, grade B gastritis (severity of gastritis) were 6, 5, 3 for the Billroth Ⅱ+Braun group, versus 8, 2, 0 for the Roux-en-Y group, showing no significant difference between the two groups ( Z=?1.468, P>0.05). Conclusions:It is safe and feasible to operate Billroth Ⅱ+Braun or Roux-en-Y anastomosis in totally 3D laparoscopic distal gastrectomy. Billroth Ⅱ+Braun anastomosis can reduce the surgical cost. Roux-en-Y anastomosis has advantages in reducing the incidence of reflux esophagitis, bile reflux and reflux gastritis.
RESUMO
<p><b>OBJECTIVE</b>To explore the clinical application of laparoscopy in gastrointestinal abdominal emergency operation for patients over 65 years old.</p><p><b>METHODS</b>Clinical data of 138 cases (age>65 years) with acute abdomen undergoing laparoscopic surgery from January 2006 to June 2014 were analyzed retrospectively. Data of 170 cases treated by laparotomy during the same period were enrolled as controls.</p><p><b>RESULTS</b>The laparoscopy group and the laparotomy group showed statistically significant differences in blood loss [(107.1±47.7) ml vs. (163.6±106.5) ml, P=0.000], postoperative complications rate [2.9%(4/138) vs. 12.9%(22/170), P=0.022], hospital stay [(10.5±7.5) d vs. (16.5±9.9) d, P=0.044], postoperative ambulation time [(25.6±7.7) h vs. (33.2±5.6) h, P=0.020], and recovery time of postoperative gastrointestinal function [(36.9±9.1) h vs. (49.3±10.6) h, P=0.031]. Patients with acute appendicitis, upper digestive tract perforation and bowel obstruction in the laparoscopy group were superior to those in the laparotomy group in hospital stay, postoperative ambulation time, recovery time of postoperative gastrointestinal function and intraoperative blood loss(all P<0.01), while no significant differences in colon perforation and mesentery diseases were found in hospital stay, intraoperative blood loss and recovery time of postoperative gastrointestinal function between the two groups (all P>0.05).</p><p><b>CONCLUSIONS</b>Compared with laparotomy, the laparoscopy offers the advantages of less trauma, faster recovery, shorter hospital stay, and lower postoperative complications rate for patients over 65 years with acute abdomen.</p>
