Abstract Objective To study the feasibility and short-term efficacy of laparoscopic radical gastrectomy for obese patients with gastric cancer. Methods From May 2007 to June 2010, 166 obese patients with gastric cancer were performed radical resection in the Department of Gastric Surgery of Fujian Medical University Union Hospital. The differences of intraoperative and postoperative situation, postoperative complications, number of resected lymph nodes and short-term survival rates between laparoscopy and open gastrectomy group were analyzed. Results Among patients, 81 patients received laparoscopy-assisted gastrectomy (LAG group) and 85 patients underwent open gastrectomy (OG group). There was no significant difference in the operation time between the two groups (P>0.05). In the aspects of intraoperative blood loss, rate of blood transfusion, increased number of leukocyte on the first postoperative day, time of temperature recovery, first flatus and postoperative hospital stays, the LAG group showed distinctive advantage than the OG group with the significant difference statistically (P<0.05). The rate of postoperative complications in LAG group and OG group were 17.2% and 20.0% and the difference was not significant (P>0.05). The difference of the mean number of retrieved lymph nodes between two groups was not significant (P>0.05). One hundred and fifty-seven patients (94.5%) were followed up for 2 to 39 months. The median time was 19 months. As for the survival curves, the survey showed there was no significant difference between two groups (P>0.05). Conclusion Laparoscopy-assisted radical gastrectomy is safe and feasible for obesity patients, which presents the superior character of minimal invasion and can achieve oncologic radical effect.     

腹腔镜与开腹手术治疗老年胃癌患者疗效的Meta分析

目的:対比分析腹腔镜与幵腹手术治疗老年胃癌患者的临床疗效。方法:检索2016年10月前发表于PubMed、Embase,MEDLINE,Cochrane Library、万方数据库、中国期刊全文数据库(CNKI)、中国生物医学期刊文献数据库(CMCC)及维普数据库中対比腹腔镜与开腹手术治疗老年胃癌患者临床疗效的文献。按预设标准进行筛选并进行质量评价,提取数据后用RevMan 5.2软件对两组患者手术指标、术后恢复情况及术后并发症进行Meta分析。结果:有19项对照研究共计2 951例患者纳入分析,其中腹腔镜组1387例,开腹组1 564例。Meta分析结果显示,与幵腹组相比,腹腔镜组术中出血量少(MD=415.85,95%CI:-414.66~-87.04,P=0.00),淋巴结清扫数量多(MD=0.62,95%CI:0.06~1.19,P=0.03)。腹腔镜组术后首次下床活动时间、术后首次肛门排气时间、术后首次经ロ进食时间及术后住院时间均短于开腹组(P0.05)。两组手术时间差异无统计学意义(MD=6.44,95%CI:-5.83~18.72,P=0.30)。腹腔镜组术后总体并发症、手术相关并发症、呼吸系统并发症及切口并发症发生率均低于开腹组(P0.05)。结论:与开腹老年胃癌根治术相比腹腔镜老年胃癌根治术同样安全、可行且具有手术创伤小、术后康复快、并发症发生率低的优势。

Total versus subtotal gastrectomy: surgical morbidity and mortality rates in a multicenter Italian randomized trial. The Italian Gastrointestinal Tumor Study Group.

OBJECTIVE: The purpose of this study was to analyze postoperative morbidity and mortality of patients included in a randomized trial comparing total versus subtotal gastrectomy for gastric cancer. SUMMARY BACKGROUND DATA: There is controversy as to whether the optimal surgery for gastric cancer in the distal half of the stomach is subtotal or total gastrectomy. Although only a randomized trial can resolve this oncologic dilemma, the first step is to demonstrate whether the two procedures are penalized by different postoperative morbidity and mortality rates. METHODS: A total of 624 patients with cancer in the distal half of the stomach were randomized to subtotal gastrectomy (320) or total gastrectomy (304), both associated with a second-level lymphadenectomy, in a multicenter trial aimed at assessing the oncologic outcome after the two procedures. The end points considered were the occurrence of a postoperative event, complication, or death and length of postoperative stay. RESULTS: Nonfatal complications and death occurred in 9% and 1% of subtotal gastrectomy patients and in 13% and 2% of total gastrectomy patients, respectively. Multivariate analysis of postoperative events showed that splenectomy or resection of adjacent organs was associated with a twofold risk of postoperative complications. Random surgery and extension of surgery influenced the length of stay. The mean length of stay, adjusted for extension of surgery, was 13.8 days for subtotal gastrectomy and 15.4 days for total gastrectomy. CONCLUSIONS: Our data show that subtotal and total gastrectomies, with second-level lymphadenectomy, performed as an elective procedure have a similar postoperative complication rate and surgical outcome. A conclusive long-term evaluation of the two operations and an accurate estimate of the oncologic impact of surgery on long-term survival, not penalized by excess surgical risk of one of the two operations, are consequently feasible.     

腹腔镜胃癌根治术对伴发慢性阻塞性肺病患者的影响

目的探讨腹腔镜胃癌根治术治疗伴发慢性阻塞性肺病（COPD）胃癌患者的可行性。方法回顾性分析第三军医大学西南医院2010年1月至2013年10月实施胃癌根治术的340例伴发COPD胃癌患者的临床资料,其中78例行开腹手术（开腹组）,262例行腹腔镜手术（腹腔镜组．腹内压维持在8～10mmHg）,比较两组术后肺部并发症的发生情况以及与术后肺部并发症发生的相关因素。结果腹腔镜组的手术时间[（220．4±19．1）rain]明显长于开腹组[（194．2±31．5）min,P=0．000],而术中失血量[（131．2±14．7）m1]明显小于开腹组[（246．7±49．0）ml,P=0．000]。腹腔镜组和开腹组患者术后肺部并发症发生率分别为5,3％（14／262）和15．4％（12／78）,差异有统计学意义（P=0．003）。多因素分析结果显示,COPD严重程度是术后出现肺部并发症的独立影响因素（P=0．031,HR=2．456,95％CI：1．306～1．789）,而采用腹腔镜手术还是开腹手术不是其独立影响因素（P=0．126）。结论应用较低腹内压的腹腔镜胃癌根治术治疗伴发轻、中度COPD的胃癌患者是安全可行的。

National outcomes and uptake of laparoscopic gastrectomy for cancer in England

Background

Gastrectomy remains the mainstay of curative treatment for gastric cancer, yet it is associated with significant postoperative mortality. The laparoscopic approach has been introduced in an attempt to improve surgical outcomes. This study examines the uptake of laparoscopic gastrectomy in England and quantifies postoperative mortality and morbidity following gastrectomy for cancer.

Methods

A population-based study of a national administrative database was undertaken. Patients undergoing gastrectomy for cancer in any National Health Services hospital in England between April 2000 and March 2010 were included. The main outcome measures were mortality, morbidity and length of stay.

Results

A total of 10,713 patients underwent gastrectomy, of which 10,233 (95.5 %) underwent open gastrectomy (OG), and 480 (4.5 %) underwent laparoscopic gastrectomy (LG). There was no significant difference in 30-day in-hospital mortality between OG and LG (5.6 % vs. 4.8 %; p = 0.461). Medical complications occurred in 2,311 (22.6 %) and 120 (25 %) patients from OG and LG groups respectively (p = 0.217). Patients in the LG groups had a shorter hospital stay than OG with median (interquartile range) of 11 (8–17) versus 14 (11–19) days respectively (p < 0.001). Readmission and reoperation rates were 10.2 versus 12.1 % (p = 0.175) and 4 versus 4.6 % (p = 0.523) for OG and LG respectively.

Conclusions

LG is increasingly being performed in England. Postoperative morbidity and mortality of LG is similar to that of OG, but it is associated with a shorter hospital stay. Data from randomised controlled trials evaluating long term survival and patients’ reported outcomes are essential before the final judgement on the value of LG in the management of gastric cancer.     

Totally laparoscopic total and subtotal gastrectomy with extended lymph node dissection for early and advanced gastric cancer: early and long-term results of a 100-patient series

BACKGROUND: Controversies exist about feasibility and oncologic effectiveness of laparoscopic gastrectomies with extended lymphadenectomy for advanced gastric cancer. The aim of our study was to determine if long-term results of these laparoscopic procedures may justify their use as an alternative to open surgery also in advanced gastric cancer. METHODS: We performed a retrospective review of 100 patients after laparoscopic surgery for gastric cancer. RESULTS: Tumor stage (S) was SIA in 21 patients, SIB in 20, SII in 17, SIIIA in 17, SIIIB in 5, and SIV in 20. Eleven total and 89 subtotal R0 gastrectomies were performed. The mean number of dissected lymph nodes was 35 +/- 18. The conversion rate was 3%. Surgical mortality and major morbidity were 6% and 13%, respectively. Overall and disease-free 5-year survival rates were 59% and 57%, respectively. CONCLUSIONS: Laparoscopic gastrectomy with extended lymphadenectomy for early and advanced gastric cancer is feasible, safe, and oncologically effective. Long-term survival rates are similar to those observed after open surgery.

Long-term oncologic outcomes of a randomized controlled trial comparing laparoscopic versus open gastrectomy with D2 lymph node dissection for advanced gastric cancer

BackgroundLaparoscopy-assisted gastrectomy is a feasible and safe procedure for treating advanced gastric cancer in terms of short-term outcomes. However, concern about long-term oncologic outcomes has limited the adoption of laparoscopy-assisted gastrectomy for advanced gastric cancer.MethodsWe launched a prospective randomized controlled trial comparing laparoscopic and open gastrectomy with D2 lymph node dissection for locally advanced gastric cancer to evaluate long-term oncologic feasibility. The 5-year overall survival, disease-free survival, and tumor recurrences have been determined on an intention-to-treat basis.ResultsBetween January 2010 and June 2012, a total of 328 patients with preoperative clinical stage T_2-4aN_0-3M₀ gastric cancer were enrolled in the trial. We excluded 6 patients with unresected tumor, and the remaining 322 patients were randomized to the laparoscopic group (162 patients) or the open group (160 patients) for radical surgery. One patient in laparoscopy-assisted gastrectomy and 4 patients in open gastrectomy were lost to follow-up immediately after discharge, leaving 317 patients (161 in laparoscopy-assisted gastrectomy and 156 in open gastrectomy) eligible for long-term analysis. The 5-year overall survival rate was 49.0% in the laparoscopic group and 50.7% in the open group, and the 5-year disease-free survival rate was 47.2% and 49.6% in the 2 groups, respectively. Kaplan–Meier curves for overall survival and disease-free survival showed no differences between the 2 groups. There was no difference in the 5-year tumor recurrence rate between the 2 procedures.ConclusionLaparoscopy-assisted gastrectomy can provide comparable long-term survival without an increase in recurrence and metastasis in treating advanced gastric cancer.

Abstract Objective To compare the surgical complication incidence between laparoscopy-assisted gastrectomy (LAG) and open gastrectomy (OG) for advanced gastric cancer (AGC) and the related risk factors of postoperative complications after radical gastrectomy. Methods A retrospective case-control study was performed comparing LAG and OG for AGC.A total of 148 patients with AGC underwent LAG between January 2010 and December 2011 in Affiliated Union Hospital of Fujian Medical University were enrolled and were compared with 148 AGC patients underwent OG during the same period. The perioperative complication morbidity and mortality were compared between the two groups. The risk factors determined postoperative complications were investigated by univariate and multivariate analysis. Results The intraoperative complication incidence was 4.1% in LAG group and 4.7% in OG group??P??0.05??.The postoperative complication incidence was 10.8% in LAG group and 20.9% in OG group??P??0.05??, among which the complication incidence of postoperative intestinal obstruction was 1.4% and 6.1% in LAG group and in OG group??P??0.05??,and the complication incidence of postoperative pulmonary infection was 3.4% and 9.5% in LAG group and in OG group??P??0.05??.There was no significant difference between the two groups in other postoperative complication incidence??P??0.05??. According to univariate analysis, depth of invasion, lymph node metastasis, operation time and laparoscopic surgery were related to postoperative complications??P??0.05??. Multivariate logistic regression analysis showed that whether laparoscopic surgery and operation time were independent risk factors for postoperative complications??P??0.05??. Conclusion There is no difference in intraoperative complication incidence between LAG and OG groups. But the postoperative complication incidence is significantly lower in LAG group than that in OG group. Whether laparoscopic surgery is an independent risk factor for postoperative complications in advanced gastric cancer.     

Laparoscopic liver resection for subcapsular hepatocellular carcinoma complicating chronic liver disease

HYPOTHESIS: Laparoscopic liver resection for subcapsular hepatocellular carcinoma in patients with chronic liver disease is associated with lower morbidity than open resections. DESIGN: A case-comparison study. SETTING: A tertiary referral center. PATIENTS AND INTERVENTION: From December 1, 1998, to November 30, 2000, 13 patients with chronic liver disease who underwent laparoscopic resection of hepatocellular carcinoma formed the laparoscopic group (LG). Tumors were 5 cm or smaller, subcapsular, and located in anterolateral segments (segments II-VI). A control group was created by matching each laparoscopic case with patients identical for liver disease, tumor size, and location and type of hepatectomy who underwent open liver resection. Fourteen patients fulfilled the criteria and formed the open group (OG). MAIN OUTCOME MEASURES: Postoperative mortality and morbidity. RESULTS: One segment or less was resected in 21 patients and 2 in 6 patients. Operative duration and cumulative portal triad clamping times were longer in the LG (267 +/- 79 minutes vs 182 +/- 57 minutes, P =.006; 68 +/- 24 minutes vs 25 +/- 19 minutes, P =.006, respectively). Mortality rates were 0% in the LG and 14% (2/14) in the OG (P =.2). Postoperative liver failure and ascites occurred in 8% (1/13) in the LG and 36% (5/14) in the OG (P =.15). Surgical margin was not different in the 2 groups. Three-year survival was significantly higher in the LG (89% vs 55%; P =.04), but 3-year recurrence rates were similar (46% vs 44%). CONCLUSION: Our study suggests that, despite longer operative and clamping times without clinical consequences, the rate of decompensation of liver disease could be lower after laparoscopy.     

Minimally Invasive Surgery for Gastric Cancer: The Future Standard of Care

Laparoscopy-assisted distal gastrectomy for gastric cancer was first reported by Kitano et al. in 1991. Laparoscopic wedge resection (LWR) and intragastric mucosal resection (IGMR) were quickly adapted for gastric cancer limited to the mucosal layer and having no risk of lymph node metastasis. Following improvements in endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), the use of LWR and IGMR for these indications decreased, and patients with gastric cancer, including those with a risk of lymph node metastases, were more likely to be managed with laparoscopic gastrectomy (LG) with lymph node dissection. Many retrospective comparative trials and randomized-controlled trials (RCT) have confirmed that LG is safe and feasible, and that short-term outcomes are better than those of open gastrectomy (OG) in patients with early gastric cancer (EGC). However, these trials did not include a satisfactory number of patients to establish clinical evidence. Thus, additional multicenter randomized-controlled trials are needed to delineate significantly quantifiable differences between LG and OG. As laparoscopic experience has accumulated, the indications for LG have been broadened to include older and overweight patients and those with advanced gastric cancer. Moreover, advanced techniques, such as laparoscopy-assisted total gastrectomy, laparoscopy-assisted proximal gastrectomy, laparoscopy-assisted pylorus-preserving gastrectomy (PPG), and extended lymph node dissection (D2) have been widely performed.

Abstract Objective To assess the safety and short-term value of laparoscopic radical gastrectomy in the elderly with gastric cancer. Methods From January 2010 to June 2012, elderly (Age≥60 years)with gastric cancer were performed radical operations in the Department of Gastrointestinal and Nutritional Surgery of Shengjing Hospital Affiliated to China Medical University. The differences of intraoperative and postoperative situation, postoperative complications, and short-term survival rates between laparoscopy and open radical gastrectomy group were analyzed. The risk factors that determined postoperative complications were investigated by univariate and multivariate analysis. Results Among patients, 102 patients received laparoscopy-assisted gastrectomy (LAG group) and 242 patients underwent open gastrectomy (OG group). There was no significant difference in the operative time and the mean number of retrieved lymph nodes between two groups (P>0.05). In the aspects of intraoperative blood loss, frequency of active anodyne using, length of incision, first flatus and postoperative hospital stays, the LAG group showed distinctive advantage than the OG group with the significant difference statistically (χ2=4.106??P=0.043). The rate of postoperative complications in LAG group and OG group were16.7% and 26.9% and the difference was significant (P<0.05). By logistic regression analysis, it showed that there were three significant factors for postoperative complications including laparoscopy-assisted gastrectomy or not, operative time and co-morbidity. Three hundred and thirteen patients (91.0%) were followed up for 6 to 36 months. The median time was 19 months. As for the survival curves, the survey showed there was no significant difference between two groups (P>0.05). Conclusion Laparoscopy-assisted radical gastrectomy is safe and feasible in elderly, which presents the superior character of minimal invasion and profit decreasing postoperative complications.     

Safety of laparoscopic radical gastrectomy in gastric cancer patients with liver cirrhosis

Background

Laparoscopic gastrectomy (LG) in gastric cancer patients with liver cirrhosis (LC) has rarely been reported. In this study, we aimed to elucidate the feasibility of LG compared with that of open gastrectomy (OG) for LC patients.

Methods

Of the 75 LC patients who underwent radical gastrectomy for gastric cancer between April 2005 and March 2014, 36 patients who underwent LG were compared with 39 patients who underwent OG. Comparisons were based on clinicopathologic characteristics, surgical outcomes, and long-term survival rates.

Results

Comparison of LG and OG revealed no significant differences in the clinicopathologic characteristics. Five patients in the LG group and eight in the OG group showed a Child–Turcotte–Pugh score (CTPs) over A. In surgical outcomes, we observed shorter operation times (191.4?±?63.9 vs. 225.9?±?77.1 min, p?=?0.039), reduced estimated blood loss (175.5?±?214.1 vs. 396.9?±?514.8 ml, p?=?0.021), and shorter hospital stays (10.4?±?4.6 vs. 13.7?±?5.8 days, p?=?0.008) in LG than OG. Regarding postoperative morbidity, 7 (19.4%) and 10 (25.6%) complications were observed in the LG and OG groups, respectively. There was no difference in complications between the two groups regardless of the CTPs. One patient with a CTPs of C succumbed to hepatic failure following LG. Long-term survival and overall and recurrence-free survival rates did not differ between the two groups.

Conclusions

Even in cases with CTPs B, LG with lymph node dissection for gastric cancer patient was safer and acceptable than OG was. Therefore, LG can be considered an alternative surgical approach in gastric cancer with LC.

Laparoscopic total gastrectomy in gastric cancer*

BACKGROUND: The aim of this retrospective study was to investigate the feasibility and safety of laparoscopic total gastrectomy in gastric cancer. METHODS: From 01/2008 to 09/2011 laparoscopic total gastrectomy was performed in 11 patients with gastric carcinoma. RESULTS: All patients had histopathologically diagnosed gastric cancer according to UICC-TNM classification: pT1 (n = 2), pT2 (n = 3), pT3 (n = 3), pT4 (n = 2), one case without histopathological malignancy in the postoperative specimen. Mean age was 69 years, mean BMI 25 and the average tumour size was 4.6 (1–10) cm. In every case R0-resection could be obtained, the amount of resected lymph nodes (25 mean) was oncologically reasonable. Conversion to open surgery was performed in two patients. Operation time was long compared to experiences in open surgery, 374 (290–465) min. There was no mortality and complication rate was acceptable. Postoperative stay was 18 days mean. CONCLUSIONS: Based on our experience laparoscopic total gastrectomy is a feasible option for treating gastric carcinomas. R0-resection in all cases and the amount of resected lymph nodes demonstrate adherence to oncologic principles.     

Laparoscopic gastrectomy for patients with a history of upper abdominal surgery: results of a matched-pair analysis

Purpose

The safety and feasibility of laparoscopic gastrectomy (LG) for patients who have undergone previous upper abdominal surgery (PUAS) remain unclear. A matched-pair analysis was conducted to compare the short-term outcomes of LG between patients with gastric cancer who had undergone PUAS and those who had not.

Methods

A matched-pair analysis was performed to compare the short-term outcomes of LG between 22 patients who had undergone PUAS and 66 who had not (control group). To compare the outcome to that of open gastrectomy (OG) following PUAS, a total of 143 consecutive OG patients treated during the same study period were also reviewed.

Results

Cholecystectomy was the most common type of PUAS, followed by gastrectomy. There were no significant differences between the groups in terms of the length of the operation, blood loss, and the number of retrieved lymph nodes or the rate of conversion to open surgery. The postoperative morbidity in the PUAS group (3/22, 13.6 %) was comparable to that of the control group (7/66, 10.6 %, P = 0.6981). There was no mortality within 30 days in either group. When compared to OG following PUAS (n = 23), LG was performed with significantly less blood loss with an equivalent postoperative outcome.

Conclusions

目的 探讨腹腔镜辅助胃癌根治术在老年胃癌患者中应用的可行性及临床疗效.方法 2007年1月至2009年12月期间,福建医科大学附属协和医院胃外科对255例年龄在65岁以上的老年胃癌患者施行D2根治术,其中行腹腔镜辅助胃癌根治术患者（腹腔镜组）116例,行常规开腹手术患者（开腹组）139例.比较两组患者术中、术后恢复、并发症发生及术后生存情况,并对术后并发症的危险因素进行分析.结果 腹腔镜组术中出血量和术中输血例数均少于开腹组,术后排气时间、进食流质时间和住院时间均短于开腹组,差异均有统计学意义（P＜0.01）;而两组患者手术时间和淋巴结清扫数目的差异无统计学意义（均P＞0.05）.腹腔镜组术后并发症发生率为15.5％（18/116）,明显低于开腹组的28.1％（39/139）（P＜0.05）.是否行腹腔镜手术（P＜0.05）、手术时间（P＜0.01）和术前合并症（P＜0.01）是老年人胃癌术后并发症的独立危险因素;手术时间（P＜0.05）和术前合并症（P＜0.01）是老年人腹腔镜辅助胃癌根治术后并发症的独立危险因素.腹腔镜组和开腹组患者术后平均生存时间分别为23.0和22.5个月,差异无统计学意义（P＞0.05）.结论 老年人腹腔镜辅助胃癌根治术能够达到与开腹手术相同的根治效果,且具有明显的微创优势.手术时间和术前合并症是老年人腹腔镜胃癌根治术后并发症的独立危险因素.
