Long-Term Outcomes of Open Versus Laparoscopic Distal Gastrectomy for T4a Gastric Cancer: A Propensity Score-Matched Cohort Study. Ann Surg Oncol 2023; 30:2278-2289. [PMID: 36469222 DOI: 10.1245/s10434-022-12897-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Accepted: 11/14/2022] [Indexed: 12/07/2022]
Abstract
BACKGROUND Laparoscopic gastrectomy for advanced gastric cancer (GC) has been applied more frequently worldwide but is still controversial for patients with serosal invasion (T4a). This study compared short- and long-term outcomes of laparoscopic distal radical gastrectomy (LDG) with open distal gastrectomy (ODG) for T4a GC. PATIENTS AND METHODS We retrospectively studied 472 patients with T4a gastric adenocarcinoma in the lower or middle third of the stomach: 231 underwent LDG and 241 underwent ODG between 2013 and 2020. Short-term outcomes included operative characteristics and complications. Long-term outcomes included overall survival (OS) and disease-free survival (DFS). Propensity score-matched (PSM) analysis was used to adjust for imbalances in baseline characteristics between groups. RESULTS The PSM strategy resulted in 294 patients (147 in each group). The LDG group had a significantly longer operating time (mean: 200 vs 190 min, p = 0.001) but reduced blood loss (mean: 50 vs 100 ml, p = 0.001). The LDG group had a higher rate of any postoperative complication (23.1% vs 12.2%, p = 0.021) but most were classified as grades I-II according to Clavien-Dindo classification. Grade III-V complications were similar between groups. Five-year OS was 69% versus 60% (p = 0.109) and 5-year DFS was 58% vs 53% (p = 0.3) in LDG and ODG groups, respectively. For tumor size < 5 cm, LDG was better in reduction of blood loss, postoperative hospital length of stay, and OS. CONCLUSIONS LDG is feasible and safe for patients with T4a GC and is comparable to ODG regarding short- and long-term outcomes. Furthermore, LDG can be a favorable option for T4a GC smaller than 5 cm.

Cancer Manag Res 2022; 14:2055-2064. [PMID: 35761822 PMCID: PMC9233543 DOI: 10.2147/cmar.s352334] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 06/13/2022] [Indexed: 12/23/2022] Open
Abstract
Background The correlation between the preoperative lymph node count (LNC) on multidetector computed tomography (MDCT) and the prognosis of gastric carcinoma (GC) remains to be defined. This research aims to evaluate the prognostic value of LNC on MDCT in GC patients based on tumor-node-metastasis (TNM) staging, using different size criteria for counting. Methods The clinical data of 126 patients with gastric adenocarcinoma undergoing gastrectomy were retrospectively analyzed. Lymph nodes greater than 8mm and 5mm on MDCT were counted and recorded. The prognostic implications of LNC on MDCT for patient survival were analyzed according to different size criteria for counting and tumor TNM staging. Results When 8mm was used as the counting criterion, LNC on MDCT had no significant effect on the overall survival (OS) of the entire cohort. In addition, the OS of T1–T2 GC patients with LNC on MDCT ≥1 was significantly worse than that of patients with LNC on MDCT <1. When 5mm was used as the counting criterion, LNC on MDCT was found to be significantly associated with the OS of the entire cohort. In the subgroup analysis, patients with relatively advanced (T3-T4, N+ and III) GC with LNC on MDCT >7 showed a significantly worse OS than those with LNC on MDCT ≤7. LNC on MDCT >7 with 5mm as the counting criterion and Stage III were independent risk factors for adverse prognosis. Conclusion The prognostic value of LNC on MDCT based on different size criteria varies in patients with different stages of GC. LNC of a smaller size (5mm) on MDCT may be a prognostic factor for patients with relatively advanced GC.

Abstract
Background: To investigate the application value of 4K high definition (HD) in laparoscopic gastrectomy by comparing the short-term outcomes and subjective perception with three-dimensional (3D) and HD vision systems. Materials and Methods: A retrospective study was conducted between September 2018 and February 2019; a total of 87 patients who underwent laparoscopic gastrectomy were enrolled and divided into three groups in terms of different type of vision system used for surgery: 4K, 3D, and HD. Demographic and clinicopathological data as well as short-term outcomes were collected and analyzed. A questionnaire survey was completed by the team of surgeons to evaluate the subjective perception of different vision systems. Results: There was no significant difference in gender, body mass index, age, American Society of Anesthesiologists (ASA) score and history of abdominal surgery, tumor location as well as type of operation, and anastomosis between the 4K, 3D, and HD groups. All patients underwent laparoscopic gastrectomy without conversion to laparotomy. There was no difference between the three groups regarding operation time (4K versus 3D versus two-dimensional (2D), 183.60 ± 52.5 versus 189.69 ± 69.87 versus 211.00 0 ± 49.33, P = .145) and estimated blood loss (4K versus 3D versus 2D, 123.60 ± 119.51 versus 150.62 ± 105.46 versus 129.00 ± 103.57, P = .602), no difference was found in time to first flatus and postoperative hospital stay between the three groups. No significant difference was found in postoperative complications between the three groups. As for pathological results, there was no difference in tumor size and tumor-node-metastasis (TNM) stage. In 4K group, the number of lymph node harvested was 32.60 ± 10.28, no difference was found compared with that of 3D (29.81 ± 8.94) and HD groups (27.69 ± 10.96). The score of group 3D was the lowest concerning asthenopia and motion sickness. On the contrary, 3D group achieved the highest score in topographical orientation and depth description. 4K group was graded the highest in terms of control co-ordination of visual angle, visual acuity, radiance, resolution ratio and frames, and refresh rate. HD group was graded significantly lower in sense of control compared with that of 4K and 3D group. No significant difference was found in color resolution and contrast. Conclusions: In conclusion, the short-term effect of 4K HD laparoscopic system is comparable with that of HD and 3D laparoscopy, whereas 4K could reduce adverse effect than traditional instrument and improve quality of surgery. The Clinical Trial Registration number is NCT01441336.

Surgery 2021; 169:1486-1492. [PMID: 33558067 DOI: 10.1016/j.surg.2020.11.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 10/31/2020] [Accepted: 11/19/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Whether laparoscopic gastrectomy is suitable for patients with serosa-invasive gastric cancer remains controversial. We performed this study to evaluate the short- and long-term outcomes after laparoscopic gastrectomy compared with after open gastrectomy. METHODS We retrospectively analyzed 906 consecutive patients with serosa-invasive gastric cancer from January 2004 to December 2014 in our center, who underwent laparoscopic gastrectomy or open gastrectomy with D2 lymphadenectomy. After propensity score matching, 334 patients were included in each group. Surgical conditions and short- and long-term results were compared. RESULTS Laparoscopic gastrectomy was associated with less estimated blood loss and longer operation time, while the number of harvested lymph nodes was not significantly different between laparoscopic gastrectomy and open gastrectomy. Patients who underwent laparoscopic gastrectomy had an earlier time to first flatus, first diet, and first ambulation and were discharged earlier. Overall and pulmonary postoperative complication rates were lower in the laparoscopic gastrectomy group. With a minimum follow-up of 60 months, the 5-year overall survival was 39.3% in the laparoscopic gastrectomy group and 34.3% in the open gastrectomy group, and the 5-year disease-free survival was 36.4% in the laparoscopic gastrectomy group and 32.7% in the open gastrectomy group. Laparoscopic gastrectomy was associated with better 5-year overall survival in patients aged ≥60 years. The overall recurrence rates and patterns were not significantly different between the 2 groups. CONCLUSION Laparoscopic gastrectomy is an alternative surgical approach for patients with serosa-invasive gastric cancer in terms of short-term outcomes and long-term survival, and it might be more advantageous for certain populations.
