Relationship between laparoscopic total gastrectomy-associated postoperative complications and gastric cancer prognosis. Updates Surg 2023; 75:149-158. [PMID: 36369627 DOI: 10.1007/s13304-022-01402-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 10/04/2022] [Indexed: 11/13/2022]
Abstract
This study aimed to investigate the incidence and prognosis of postoperative complications after laparoscopic total gastrectomy (LTG) for gastric cancer (GC). We retrospectively enrolled 411 patients who underwent curative LTG for GC at seven institutions between January 2004 and December 2018. The patients were divided into two groups, complication group (CG) and non-complication group (non-CG), depending on the presence of serious postoperative complications (Clavien-Dindo grade III [≥ CD IIIa] or higher complications). Short-term outcomes and prognoses were compared between two groups. Serious postoperative complications occurred in 65 (15.8%) patients. No significant difference was observed between the two groups in the median operative time, intraoperative blood loss, number of lymph nodes harvested, or pathological stage; however, the 5-year overall survival (OS; CG 66.4% vs. non-CG 76.8%; p = 0.001), disease-specific survival (DSS; CG 70.1% vs. non-CG 76.2%; p = 0.011), and disease-free survival (CG 70.9% vs. non-CG 80.9%; p = 0.001) were significantly different. The Cox multivariate analysis identified the serious postoperative complications as independent risk factors for 5-year OS (HR 2.143, 95% CI 1.165-3.944, p = 0.014) and DSS (HR 2.467, 95% CI 1.223-4.975, p = 0.011). A significant difference was detected in the median days until postoperative recurrence (CG 223 days vs. non-CG 469 days; p = 0.017) between the two groups. Serious postoperative complications after LTG negatively affected the GC prognosis. Efforts to decrease incidences of serious complications should be made that may help in better prognosis in patients with GC after LTG.

Surg Endosc 2020; 34:5428-5438. [PMID: 31993813 DOI: 10.1007/s00464-019-07338-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Accepted: 12/24/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND The aim of this study was to evaluate the short-term outcomes and prognosis of laparoscopy-assisted total gastrectomy (LTG) in elderly patients with gastric cancer. METHODS The clinical data of 275 patients aged over 65 years undergoing open total gastrectomy (OTG, n = 184) or laparoscopy-assisted total gastrectomy (LTG, n = 91) were reviewed from January 2015 to August 2017 at the First Affiliated Hospital of the University of Science and Technology of China. Short-term outcomes were compared between the two groups, and risk factors for postoperative complications were explored. In addition, the 2-year overall survival (OS) and disease-free survival (DFS) were investigated for both groups. RESULTS Except for the ASA score (P = 0.01), there was no significant difference regarding patient baselines between the two groups. Patients in the LTG group had a longer operative time (P < 0.001), less intraoperative blood loss (P = 0.004), a shorter time of resumption to a semi-liquid diet (P < 0.001) and a shorter postoperative hospital stay (P = 0.001). The incidence of pulmonary complications was significantly lower in the LTG group than in the OTG group (4.4% vs. 13%, P = 0.026). The number of lymph nodes harvested in the LTG group was higher than that in the OTG group (20.7 ± 7.4 vs. 17.5 ± 6.9, P = 0.001), and the proportion of patients with TNM stage III gastric cancer was higher in the LTG group than in the OTG group (P = 0.035). There was no significant difference in the 2-year OS rate or 2-year DFS rate between the two groups (P = 0.057 and P = 0.344). Sex, age, preoperative comorbidity, intraoperative blood loss, and TNM stage were identified as independent prognostic factors for postoperative survival. CONCLUSION Comparing with OTG, LTG is feasible and contributes to less surgical trauma and a faster recovery after total gastrectomy. In addition, LTG contributes to a lower risk of postoperative pulmonary complications. Regarding oncological results, LTG is more effective for lymph node dissection and has a comparable long-term prognosis as OTG.

Ann Gastroenterol Surg 2019; 3:231-238. [PMID: 31131351 PMCID: PMC6524106 DOI: 10.1002/ags3.12232] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 12/18/2018] [Accepted: 12/20/2018] [Indexed: 12/11/2022] Open
Abstract
Since the late 1990s, perioperative care through the enhanced recovery after surgery (ERAS, European Society for Clinical Nutrition and Metabolism [ESPEN]) program has spread. ERAS protocols aim to reduce surgical complications, improving postoperative outcomes and thereby saving resources by addressing various clinical elements through a multidisciplinary approach or based on evidence. In the field of gastric cancer, the philosophy of ERAS has gradually become accepted and, in 2014, consensus guidelines for enhanced recovery after gastrectomy were published. These guidelines consist of "procedure-specific" guidelines and "general (not procedure-specific) enhanced recovery items." In this review, we focused on the procedure-specific guidelines and tried to update the contents of every element of the procedure-specific guidelines. The procedure-specific guidelines consist of the following eight elements: "Preoperative nutrition," "Preoperative oral pharmaconutrition," "Access (of gastrectomy)," "Wound catheters and transversus abdominis plane block," "Nasogastric/Nasojejunal decompression," "Perianastomotic drains," "Early postoperative diet and artificial nutrition," and "Audit." On reviewing papers supporting these elements, it was reconfirmed that the recommendations of the guidelines are pertinent and valid. Four meta-analyses concerning the evaluation of ERAS protocols for gastric cancer were included in this review. Every study showed that the ERAS protocol reduced the cost and duration of hospital stay without increasing surgical complication rates, suggesting that ERAS is effective for gastric cancer surgery. However, it cannot be said that ERAS has achieved full penetration in Japan because most evidence is established in Western countries. Future studies must focus on developing a new ERAS protocols appropriate to Japanese conditions of gastric cancer.

Abstract
OBJECTIVES The safety and surgical oncology of laparoscopy-assisted total gastrectomy (LATG) remain inconclusive and challenging. This study aimed to compare the short-term and long-term outcomes between LATG and open total gastrectomy (OTG) procedures. RESULTS In the all-included analyses, there were 69 patients in the LATG group and 268 in the OTG group. LATG was as safe as OTG without increasing postoperative morbidity and mortality. Stage imbalance might introduce differences in the numbers of harvested lymph nodes in LATG (34.4 ± 12.0) and OTG (40.9 ± 16.9), whereas 95.7% of patients underwent D2/D2+ dissection during the LATG procedure. After a median 31 months of follow-up, the overall survival outcomes were comparable between the LATG and OTG procedures (HR = 1.16, 95% CI 0.68-1.97). Sensitivity analysis found comparable node retrieval and stage-specific or treatment-specific overall survival. MATERIALS AND METHODS A retrospective case-control study was conducted among gastric cancer patients who underwent either LATG or OTG with curative intention between June 2006 and December 2015. Data retrieval was based on the Surgical Gastric Cancer Patient Registry in the West China Hospital. The primary outcome was overall survival. The secondary outcomes were postoperative complication incidence and severity, operation duration, blood loss, number of harvested lymph nodes, and postoperative hospital stay. Matched pairwise case-control comparisons were performed as a sensitivity analysis. CONCLUSIONS LATG by experienced surgeons possibly has comparable short-term surgical outcomes and long-term survival outcomes compared with OTG for gastric cancer patients. However, high-quality RCTs are necessary before confirmative judgment and recommendation as an optional treatment in general practice.

Postoperative Complications of Laparoscopic Total Gastrectomy versus Open Total Gastrectomy for Gastric Cancer in a Meta-Analysis of High-Quality Case-Controlled Studies. Gastroenterol Res Pract 2016; 2016:2617903. [PMID: 28042292 PMCID: PMC5155090 DOI: 10.1155/2016/2617903] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Accepted: 11/03/2016] [Indexed: 12/17/2022] Open
Abstract
Background. Some meta-analyses of case-controlled studies (CCSs) have shown that laparoscopic or laparoscopy-assisted total gastrectomy (LTG) had some short-term advantages over open total gastrectomy (OTG). However, postoperative complications differed somewhat among the meta-analyses, and some CCSs included in the meta-analyses had mismatched factors between LTG and OTG. Methods. CCSs comparing postoperative complications between LTG and OTG were identified in PubMed and Embase. Studies matched for patients' status, tumor stage, and the extents of lymph-node dissection were included. Outcomes of interest, such as anastomotic, other intra-abdominal, wound, and pulmonary complications, were evaluated in a meta-analysis performed using Review Manager version 5.3 software. Result. This meta-analysis included a total of 2,560 patients (LTG, 1,073 patients; OTG, 1,487 patients) from 15 CCSs. Wound complications were significantly less frequent in LTG than in OTG (n = 2,430; odds ratio [OR] 0.30, 95% confidence interval [CI] 0.29-0.85, P = 0.01, I2 = 0%, and OR 0.46, 95% CI 0.17-0.52, P < 0.0001, I2 = 0%). However, the incidence of anastomotic complications was slightly but not significantly higher in LTG than in OTG (n = 2,560; OR 1.44, 95% CI 0.96-2.16, P = 0.08, I2 = 0%). Conclusion. LTG was associated with a lower incidence of wound-related postoperative complications than was OTG in this meta-analysis of CCSs; however, some concern remains about anastomotic problems associated with LTG.

World J Gastroenterol 2016; 22:5694-5717.

Abstract
Radical gastrectomy with an adequate lymphadenectomy is the main procedure which makes it possible to cure patients with resectable gastric cancer (GC). A number of randomized controlled trials and meta-analysis provide phase III evidence that laparoscopic gastrectomy is technically safe and that it yields better short-term outcomes than conventional open gastrectomy for early-stage GC. While laparoscopic gastrectomy has become standard therapy for early-stage GC, especially in Asian countries such as Japan and South Korea, the use of minimally invasive techniques is still controversial for the treatment of more advanced tumours, principally due to existing concerns about its oncological adequacy and capacity to carry out an adequately extended lymphadenectomy. Some intrinsic drawbacks of the conventional laparoscopic technique have prevented the worldwide spread of laparoscopic gastrectomy for cancer and, despite technological advances in recent year, it remains a technically challenging procedure. The introduction of robotic surgery over the last ten years has implied a notable mutation of certain minimally invasive procedures, making it possible to overcome some limitations of the traditional laparoscopic technique. Robot-assisted gastric resection with D2 lymph node dissection has been shown to be safe and feasible in prospective and retrospective studies. However, to date there are no high quality comparative studies investigating the advantages of a robotic approach to GC over traditional laparoscopic and open gastrectomy. On the basis of the literature review here presented, robot-assisted surgery seems to fulfill oncologic criteria for D2 dissection and has a comparable oncologic outcome to traditional laparoscopic and open procedure. Robot-assisted gastrectomy was associated with the trend toward a shorter hospital stay with a comparable morbidity of conventional laparoscopic and open gastrectomy, but randomized clinical trials and longer follow-ups are needed to evaluate the possible influence of robot gastrectomy on GC patient survival.

Abstract
BACKGROUND The aim of this study was to compare the results of laparoscopy-assisted total gastrectomy with those of open total gastrectomy for early gastric cancer. METHODS Patients with gastric cancer who underwent total gastrectomy with curative intent in three Korean tertiary hospitals between January 2003 and December 2010 were included in this multicentre, retrospective, propensity score-matched cohort study. Cox proportional hazards regression models were used to evaluate the association between operation method and survival. RESULTS A total of 753 patients with early gastric cancer were included in the study. There were no significant differences in the matched cohort for overall survival (hazard ratio (HR) for laparoscopy-assisted versus open total gastrectomy 0.96, 95 per cent c.i. 0.57 to 1.65) or recurrence-free survival (HR 2.20, 0.51 to 9.52). The patterns of recurrence were no different between the two groups. The severity of complications, according to the Clavien-Dindo classification, was similar in both groups. The most common complications were anastomosis-related in the laparoscopy-assisted group (8.0 per cent versus 4.2 per cent in the open group; P = 0.015) and wound-related in the open group (1.6 versus 5.6 per cent respectively; P = 0.003). Postoperative death was more common in the laparoscopy-assisted group (1.6 versus 0.2 per cent; P = 0.045). CONCLUSION Laparoscopy-assisted total gastrectomy for early gastric cancer is feasible in terms of long-term results, including survival and recurrence. However, a higher postoperative mortality rate and an increased risk of anastomotic leakage after laparoscopic-assisted total gastrectomy are of concern.

Abstract
AIM: To investigate the anastomotic complications of esophagojejunostomy (EJS) after laparoscopic total gastrectomy (LTG), we reviewed retrospective studies.
METHODS: A literature search was conducted in PubMed for studies published from January 1, 1994 through January 31, 2015. The search terms included “laparoscopic,”“total gastrectomy,” and “gastric cancer.” First, we selected 16 non-randomized controlled trials (RCTs) comparing LTG with open total gastrectomy (OTG) and conducted an updated meta-analysis of anastomotic complications after total gastrectomy. The Newcastle-Ottawa scoring system (NOS) was used to assess the quality of the non-RCTs included in this study. Next, we reviewed anastomotic complications in 46 case studies of LTG to compare the various procedures for EJS.
RESULTS: The overall incidence of anastomotic leakage associated with EJS was 3.0% (30 of 984 patients) among LTG procedures and 2.1% (31 of 1500 patients) among OTG procedures in the 16 non-RCTs. The incidence of anastomotic leakage did not differ significantly between LTG and OTG (odds OR = 1.42, 95%CI: 0.86-2.33, P = 0.17, I2 = 0%). Anastomotic stenosis related to EJS was reported in 72 (2.9%) of 2484 patients, and the incidence was 3.2% among LTG procedures and 2.7% among OTG procedures. The incidence of anastomotic stenosis related to EJS was slightly, but not significantly, higher in LTG than in OTG (OR = 1.55, 95%CI: 0.94-2.54, P = 0.08, I2 = 0%). The various procedures for LTG were classified into six categories in the review of case studies of LTG. The incidence of EJS leakage was similar (1.1% to 3.2%), although the incidence of EJS stenosis was relatively high when the OrVilTM device was used (8.8%) compared with other procedures (1.0% to 3.6%).
CONCLUSION: The incidence of anastomotic complications associated with EJS was not different between LTG and OTG. Anastomotic stenosis was relatively common when the OrVilTM device was used.

Abstract
BACKGROUND To compare the effects of laparoscopic-assisted gastrectomy (LAG) and open gastrectomy (OG) on serum interleukin-6 (IL-6) levels in gastric cancer (GC) patients from Asia. METHODS The following scientific literature databases were searched for relevant clinical studies: PubMed, EBSCO, Ovid, Wiley, Web of Science, Cochrane library, EMBASE, WANFANG and VIP databases. The studies retrieved from database searches were screened based on stringent inclusion and exclusion criteria to select high quality cohort studies for the present meta-analysis. The data extracted from final selected studies were analyzed using STATA 12.0 software. RESULTS A total of 54 studies were initially retrieved from database searches, and 11 clinical cohort studies were eventually enrolled in this meta-analysis. The 11 selected studies contained a combined total of 767 GC patients (427 patients in LAG group and 340 patients in OG group). Meta-analysis results demonstrated that postoperative serum IL-6 levels in GC patients in LAG group was significantly lower than the OG group (SMD = -2.16, 95% CI = -3.19 ~ -1.14, P < 0.001). The difference in serum IL-6 levels between the preoperative and postoperative GC patients was significantly lower in the LAG group compared to the difference found in the OG group (SMD = -3.44, 95% CI = -4.87 ~ -2.01, P < 0.001). Subgroup analysis based on country showed that, in both Chinese and Japanese GC patients, the postoperative increase in serum IL-6 levels in LAG group were significantly lower than the increase observed in the OG group (all P < 0.05). In Korean GC patients, the postoperative increase in serum IL-6 levels was not significantly different between the LAG group and OG group (all P > 0.05). CONCLUSION Our results provide strong evidence that LAG is associated with significantly lower serum IL-6 levels, compared to OG. Thus, LAG carries markedly lower risk of adverse inflammatory reactions in GC patients among Asian population.

[PMID: 25666184 DOI: 10.1007/s10120-015-0474-3] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2014] [Accepted: 01/25/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) has been performed since 1999. Although surgical outcomes have been reported from Japan, Korea, China, and many Western countries, the effectiveness of this technique has not been conclusively established. This study therefore aimed to review the literature systematically. METHODS Our search of the research literature identified 150 studies, which were mostly retrospective and from single institutions. RESULTS There has recently been a remarkable increase in the number of studies from Korea, and the number of patients included in studies has increased since 2009. In most studies, the surgical procedures were longer, blood loss was reduced, and the number of retrieved lymph nodes was the same in the LTG group as in the open total gastrectomy group. The incidence of postoperative complications and that of inflammation during postoperative recovery were the same in these two groups. CONCLUSIONS During LTG, the method used for esophagojejunostomy is important for surgical reliability and to reduce postoperative complications. There has been rapid development of new techniques from the level of esophagojejunostomy through a small skin incision to the high level of intracorporeal esophagojejunostomy using various techniques. A nationwide prospective phase II study is urgently needed to establish the value of LTG.

[PMID: 25270612 DOI: 10.1007/s00464-014-3825-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2014] [Accepted: 08/12/2014] [Indexed: 12/25/2022]
Abstract
BACKGROUND We introduced a new, safe and simple intracorporeal Billroth II (B-II) gastrojejunostomy technique using laparoscopic linear staplers with totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. We further compared the short-term operative outcomes between intracorporeal B-II gastrojejunostomy with TLDG and extracorporeal B-II gastrojejunostomy with laparoscopy-assisted distal gastrectomy (LADG). METHODS From January 01, 2012 to January 31, 2013, a total of 36 patients with gastric cancer underwent TLDG and LADG. Overall, 11 patients underwent intracorporeal B-II gastrojejunostomy with TLDG, and 25 patients underwent a mini-laparotomy incision for extracorporeal B-II anastomosis with LADG. Perioperative parameters, including patient and tumor characteristics, short-term postoperative outcomes, and anastomosis-related complications, were analyzed to compare the two operations. RESULTS The time to first flatus, the time on a liquid diet, and the mean postoperative length of hospital stay were significantly different between the groups (P < 0.05). In the TLDG group, the postoperative time to first flatus and the mean postoperative length of hospital stay were significantly shorter than in the LADG group (2.6 ± 0.20 vs. 3.8 ± 0.1 days; 10 ± 1.84 vs. 12.7 ± 3.35 days). However, the operation-related costs were significantly greater for totally laparoscopic distal gastrectomy (P < 0.001). The mean number of staples used in TLDG was six compared with four in LADG. CONCLUSION Our new intracorporeal B-II anastomosis method using laparoscopic linear staplers with TLDG was safe, feasible, and minimally invasive compared with extracorporeal B-II gastrojejunostomy with LADG. At the same time, one of its characteristics of our technique is to avoid stricturing of the efferent loop or afferent loop of the jejunum when the entry hole is closed with a stapler.
