[PMID: 37046761 PMCID: PMC10093354 DOI: 10.3390/cancers15072100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 03/25/2023] [Accepted: 03/30/2023] [Indexed: 04/03/2023] Open
Abstract
We investigated the impact of the difference in fat distribution between men and women on long-term prognosis after gastrectomy in patients with advanced gastric cancer. Patients with advanced gastric cancer deeper than p-T2 who underwent gastrectomy between April 2008 and June 2018 were included. Visceral fat mass index (VFI) and subcutaneous fat mass index (SFI) were calculated by dividing the cross-sectional area at the umbilical level by the height squared. The medians of VFI and SFI by sex were defined as cut-off values, below which values were defined as low VFI and low SFI. Of the 485 patients, 323 (66.6%) were men and 162 (33.4%) were women. Men with a low VFI had a significantly worse overall survival (OS) (p = 0.004) and women with a low SFI had a significantly worse OS (p = 0.007). Patients with a low VFI and low SFI had the worst prognosis. Multivariate analysis showed that a low VFI was an independent poor prognostic factor in men, while a low SFI was an independent poor prognostic factor in women. In conclusion, a low visceral fat mass in men and a low subcutaneous fat mass in women were independent poor prognostic factors after radical gastrectomy for advanced gastric cancer.

Abstract
BACKGROUND There is no consensus on the relation between visceral fat mass and long-term postoperative prognosis in patients with upper gastrointestinal (GI) cancer. OBJECTIVES The purpose of this study was to investigate the association of preoperative visceral fat mass with postoperative complications and overall survival (OS) in patients with upper GI cancer. METHODS We searched MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE (Dialog), the WHO International Clinical Trials Platform Search Portal, and ClinicalTrials.gov and identified observational studies published from inception through 20 July 2022. We conducted a systematic review and random-effects meta-analysis of studies including patients who were surgically treated for upper GI cancer and whose visceral fat mass was assessed on the basis of body composition. We independently assessed the risk of bias and quality of evidence using the Quality In Prognosis Studies and the Grading of Recommendations, Assessment, Development, and Evaluation approach, respectively. The primary outcome was OS. HRs and 95% CIs for OS were pooled. RESULTS Ninety-one studies (n = 20,583) were included. All studies used computed tomography (CT) to assess the body composition of patients. Twenty-four studies reported the relation between high visceral fat and postoperative outcomes, and their results were synthesized. Compared with low visceral adipose tissue, high visceral adipose tissue assessed by CT may improve OS (HR: 0.69; 95% CI: 0.55, 0.87; I2 = 65%; n = 3407). The risk of bias for OS in each study was moderate or high. The certainty of evidence for OS was very low because of inconsistency in the forest plot, the moderate or high risk of bias, and publication bias. CONCLUSIONS High visceral fat may be associated with improved OS after radical resection in patients with upper GI cancer. Further studies are needed to confirm these findings and mitigate the risk.

Preoperative High Visceral Fat Increases Severe Complications but Improves Long-Term Prognosis after Gastrectomy for Patients with Advanced Gastric Cancer: A Propensity Score Matching Analysis.

Abstract
This study investigated the paradox of high visceral fat mass increasing severe complications but improving long-term prognosis after radical gastrectomy for gastric cancer. This was a retrospective cohort study of consecutive patients with primary stage I–III gastric cancer who underwent gastrectomy between April 2008 and June 2018. The visceral adipose tissue index (VAI) was calculated by dividing the visceral fat mass preoperatively measured on computed tomography by the square of the height. Patients with VAIs below the median cut-off value were classified as low-VAI, while those above it were classified as high-VAI. We compared the postoperative complication rate and overall survival (OS) in the low- and high-VAI groups after adjusting patient characteristics using propensity score matching (PSM). There were 155 patients in both groups after PSM. After matching, there was no significant difference in factors other than BMI and VAI that were not adjusted. The high-VAI group had more severe postoperative complications (p = 0.018), but the OS was significantly better in the high-VAI group (hazard ratio 0.611, 95%CI 0.403–0.928, p = 0.021). Preoperative high visceral fat mass not only increased severe complications, but also improved OS after gastrectomy in patients with advanced gastric cancer.

Abstract
BACKGROUND The study aimed to evaluate the impact of sarcopenia on short- and long-term outcomes for laparoscopic colorectal cancer surgery. METHODS Study participants were 209 patients who underwent laparoscopic surgery for any stage of colorectal cancer between 2016 and 2017. Skeletal muscle indices were calculated with preoperative computed tomography. Patients were divided into sarcopenic and non-sarcopenic groups based on index cut-off values and variables were compared. RESULTS The prevalence of sarcopenia was 41.1%. Sarcopenic patients experienced shorter operative times and a lower incidence of surgical site infections; however, the incidence of severe postoperative complications and readmission were increased for this group. Although the 3-year disease-free survival rate was not statistically different between groups, sarcopenic patients had a significantly worse 3-year overall survival rate compared with than the non-sarcopenic group. CONCLUSION Sarcopenia has both favorable and unfavorable effects on patients who underwent laparoscopic colorectal cancer surgery.

Abstract
BACKGROUND The number of overweight gastric cancer patients who are undergoing laparoscopic gastrectomy (LG) has increased in Japan. However, the relationship between obesity and surgical outcomes of LG remains unclear. Therefore, this study aimed to evaluate the effect of visceral fat area (VFA) on surgical outcomes of LG for gastric cancer compared to the body mass index (BMI). METHODS This study was a retrospective, cohort study that included 587 patients who underwent LG in our institution between January 2015 and December 2019. The patients were divided into two groups according to VFA (< 100 cm2 and ≥ 100 cm2) and BMI (< 25 kg/m2 and ≥ 25 kg/m2) values, respectively. Surgical outcomes and postoperative complications were compared between the low and high groups for each VFA and BMI value. Propensity score matching was used to minimize potential selection bias. RESULTS After propensity score matching, 144 pairs of patients in the VFA group and 82 pairs of patients in the BMI group were extracted. Operative time (p = 0.003), intraoperative blood loss (p = 0.0006), and CRP levels on postoperative day 1 (p = 0.002) and on postoperative day 3 (p = 0.004) were significantly higher in the high-VFA group than in the low-VFA group. However, these surgical outcomes were not significantly different between the high-BMI and low-BMI groups. There was no strong correlation between VFA and BMI (R2 = 0.64). There were no significant differences in postoperative complications between the high and low groups for both VFA and BMI values. On multivariate analysis, high VFA was an independent predictor of operative time, but it was not significantly associated with the incidence of postoperative complications. CONCLUSION VFA is a better indicator of longer operative time than BMI. However, increased VFA did not affect postoperative complications.

Abstract
The impact of body mass index (BMI) on surgical outcomes has previously been studied in relation to several oncological procedures. Regarding gastric cancer surgery, published results have been contradicting in terms of degree of technical difficulty, risk of postoperative complications and survival. In an attempt to clarify these issues, we performed a meta-analysis to evaluate the impact of obesity (defined as BMI ≥ 30 kg/m2) on outcomes after gastrectomy for gastric cancer. The meta-analysis was performed according to the PRISMA guidelines. Eligible studies were identified through search of PubMed, EMBASE, Web of Science and Cochrane Library databases. Quality assessment was performed using the Newcastle-Ottawa scale. The meta-analysis was conducted using random-effects modeling. A total of 11 studies with 13 538 patients were eligible for analysis. Obesity was associated with a significantly longer operation time (WMD = 19.38 min, 95% CI 12.72-26.04; p < 0.001), increased risk of overall complications (RR = 1.23, 95% CI 1.06-1.42; p = 0.005) and pulmonary complications (RR = 3.81, 95% CI 2.24-6.46; p < 0.001). These findings remained irrespective type of surgery (laparoscopic vs. open) and type of gastrectomy. No differences were found regarding blood loss, number of resected lymph nodes, anastomotic leakage, hospital stay, 30-day mortality and 5-year overall survival. The conclusion of the current meta-analysis is that high BMI in gastric cancer patients is associated with longer operative time and more frequent overall postoperative complications. However, it has no negative impact on survival, indicating that gastrectomy is a safe procedure for this group of patients.

Abstract
Background Obesity can affect postoperative outcomes of gastrectomy. Visceral fat area is superior to body mass index in predicting postoperative complications. However, visceral fat area measurement is time-consuming and is not optimum for clinical use. Meanwhile, trunk fat volume (TFV) can be easily measured via bioelectrical impedance analysis. Hence, the current study aimed to determine the ability of TFV to predict the occurrence of complications after gastrectomy. Methods We retrospectively reviewed patients who underwent curative gastrectomy for gastric cancer between November 2016 and November 2019. The trunk fat volume-to-the ideal amount (%TFV) ratio was obtained using InBody 770 before surgery. The patients were classified into the obese and nonobese groups according to %TFV (TFV-H group, ≥ 150%; TFV-L group, < 150%) and body mass index (BMI-H group, ≥ 25 kg/m2; BMI-L group, < 25 kg/m2). We compared the short-term postoperative outcomes (e.g., operative time, blood loss volume, number of resected lymph nodes, and duration of hospital stay) between the obese and nonobese patients. Risk factors for complications were assessed using logistic regression analysis. Results In total, 232 patients were included in this study. The TFV-H and BMI-H groups had a significantly longer operative time than the TFV-L (p = 0.022) and BMI-L groups (p = 0.006). Moreover, the TFV-H group had a significantly higher complication rate (p = 0.004) and a lower number of resected lymph nodes (p < 0.001) than the TFV-L group. In the univariate analysis, %TFV ≥ 150, total or proximal gastrectomy, and open gastrectomy were found to be potentially associated with higher complication rates (p < 0.1 for all). Moreover, the multivariate analysis revealed that %TFV ≥ 150 (OR: 2.73; 95% CI: 1.37–5.46; p = 0.005) and total or proximal gastrectomy (OR: 3.57; 95% CI: 1.79–7.12; p < 0.001) were independently correlated with postoperative morbidity. Conclusions %TFV independently affected postoperative complications. Hence, it may be a useful parameter for the evaluation of obesity and a predictor of complications after gastrectomy.

Abstract
BACKGROUND Robotic surgery has been widely adopted for complex procedures to overcome technical limitations of open or laparoscopic methods. However, evidence of any subsequent benefit is lacking. This study was undertaken to compare open, laparoscopic, and robotic gastrectomy in technically demanding procedure-D2 dissection in obese patients with gastric cancer. METHODS Data collected between 2010 and 2018 on D2 gastrectomy in obese patients with gastric cancer were used to conduct retrospective analysis, comparing short- and long-term outcomes of open, laparoscopic, and robotic techniques. RESULTS In a total of 185 patients, there were 69 open, 62 laparoscopic, and 54 robotic gastrectomy procedures. Median ages for respective surgical groups were 66 (interquartile range [IQR]: 61-64 years), 63 (IQR: 59-63), and 59 years (IQR: 56-60 years) (p = 0.009). Early-stage gastric cancer ranked proportionately higher in the laparoscopic group (p = 0.005), but operative times were similar among groups. Estimated blood loss (p < 0.001) and drainage volumes (p = 0.001) were higher in the open group, relative to others. Although a robotic approach performed best in overall compliance and in mean number of retrieved lymph node, observed rates of early or late complications did not differ by technique. The open group experienced significantly poorer overall (p = 0.039) and relapse-free (p < 0.001) survival compared with the laparoscopic or robotic group. Robotic surgery emerged from multivariable Cox regression as a protective factor for relapse-free survival (HR = 0.314, 95% CI 0.116-0.851). CONCLUSIONS In obese patients with gastric cancer, robotic gastrectomy with D2 lymphadenectomy proved comparable to open or laparoscopic technique short-term, yielding better long-term outcomes.

[PMID: 30937713 DOI: 10.1007/s11605-019-04199-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2018] [Accepted: 03/05/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND Our study investigated the effect of lymph node (LN) noncompliance on the long-term prognosis of patients after laparoscopic total gastrectomy (LTG) and explored the risk factors of LN noncompliance. METHODS The clinicopathological data of gastric cancer (GC) patients who underwent LTG with D2 lymphadenectomy from June 2007 to December 2013 were prospectively collected and retrospectively analyzed. The effects of LN noncompliance on the long-term prognosis of patients with GC after LTG were explored. RESULTS The overall LN noncompliance rate was 51.9%. The survival rate of patients after LTG with LN compliance was significantly superior to that of patients with LN noncompliance (p = 0.013). The stratified analysis of TNM stage indicated that there was no difference between the OS of stage I patients with LN compliance and those with LN noncompliance; OS of stage II/III patients with LN compliance was significantly better than that of those with LN noncompliance. Cox regression analyses showed that LN noncompliance was an independent risk factor for OS. Logistic regression analysis showed that high BMI (≥ 25 kg/m2) was an independent risk factor for preoperative prediction of LN noncompliance in cStage II/III patients. Patients with a high BMI were more likely to have LN noncompliance during surgery, especially during the dissections of #6, #8a, and #12a LN stations. CONCLUSIONS LN noncompliance was an independent risk factor for poor prognosis in patients with advanced gastric cancer (AGC) after LTG. Patients with high BMI were more likely to have LN noncompliance, especially during the dissections of #6, #8a, and #12a LN stations. LN tracing was recommended for these patients to reduce the rate of LN noncompliance.

Laparoscopic total gastrectomy for upper-middle advanced gastric cancer: analysis based on lymph node noncompliance. Gastric Cancer 2020; 23:184-194.

Abstract
BACKGROUND Increasing number of clinical studies have shown that laparoscopic distal gastrectomy (LDG) with D2 lymph node (LN) dissection is an effective method for the treatment of advanced gastric cancer (AGC). However, reports on the technical feasibility and oncology efficacy of laparoscopic total gastrectomy (LTG) in the treatment of AGC are rare. METHODS A retrospective analysis of the clinicopathologic data of 1313 patients with clinical stage of cT2-4aN0-3M0 undergoing laparoscopic radical gastrectomy with D2 LN dissection from June 2007 to December 2013 was performed. Noncompliance was defined as patients with more than one LN station absence as described in the protocol for D2 lymphadenectomy in the Japanese Gastric Cancer Association (JGCA). According to the literature, it was subdivided into LN compliance group (all LN stations were detected), minor LN noncompliance group (1-2 LN stations were not detected), major LN noncompliance group (more than 2 LN stations were not detected). Based on the LN noncompliance, the surgical indications of LTG were analyzed with LDG as control. RESULTS Among the 1313 patients, 197 (39.20%) patients and 321(39.71%) patients in the LDG group and the LTG group had minor LN noncompliance, 59(11.70%) patients and 163(20.10%) patients had major LN noncompliance. The difference in the extent of LN noncompliance between the two groups was statistically significant (p < 0.001). COX proportional hazards regression analysis elucidated that the LN noncompliance was an independent prognostic factor for overall survival (OS). BMI ≥ 25 kg/m2 and the history of previous abdominal surgery (PAS) were independent risk factors for major LN noncompliance in LTG group (p < 0.05), with which patients were defined as a LN noncompliance high-risk group. With the exception of LN noncompliance high-risk group, the difference in the extent of LN noncompliance between LTG group and LDG group was still statistically significant (p = 0.008). Tumor diameter > 60 mm is a preoperative risk factor for station #5 LN noncompliance, and no preoperative risk factors for station #6 LN noncompliance were found, with which patients were defined as LN noncompliance middle-risk group. CONCLUSION LN noncompliance is an independent prognostic factor for poor prognosis in patients after LTG. Based on this finding, patients with BMI ≥ 25 kg/m2, history of PAS and tumor diameter > 60 mm in the advanced stage of upper-middle gastric cancer represent high/middle-risk groups with LN noncompliance in LTG surgery, which should be carefully selected.

Abstract
Abdominal visceral fat is a well-recognized a risk for colorectal cancer (CRC). In contrast to the risk for CRC, the impact of adiposity in disease staging and patient survival is less well-established. Our aim was to critically review the literature on the influence of adiposity assessed by different methods routinely used in clinical settings, on CRC staging and prognosis. In the 32 studies reviewed, overweight was initially identified as a survival advantage, an evidence that was later challenged by studies suggesting that body adiposity is likely to have a deleterious effect in CRC outcomes, particularly in males. Hence, whether obesity has a negative impact in CRC staging or prognosis remains controversial. In sum, addressing the impact of body fat in CRC biological behavior is still an unmet need. Understanding how adiposity influences CRC staging and prognosis could allow further patient risk stratification for devising targeted interventions and improve clinical outcomes.

Asian J Surg 2019; 43:69-77. [PMID: 31036475 DOI: 10.1016/j.asjsur.2019.03.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 03/19/2019] [Accepted: 03/28/2019] [Indexed: 02/06/2023] Open
Abstract
The aim of this study was to evaluate the impact of high body mass index (BMI) on surgical outcome of laparoscopic gastrectomy for gastric cancer (GC). Systematic literature search was performed using PubMed and Embase databases. The relevant data were extracted, and surgical outcomes and postoperative complications were compared between BMI≥25 kg/m2 and BMI<25 kg/m2 group using a fixed effect model or random effect model. 16 studies, with a total of 9572 GC patients, were included in this meta-analysis. The results indicated that operation time was significantly longer (WMD:16.22, 95% CI: 14.10-18.34, P < 0.001; I2 = 0%) and the number of lymph nodes retrieved was significantly fewer (WMD:-2.11, 95%CI: -3.14, -1.07, P < 0.001; I2 = 64.0%) in high BMI patients than in other patients. In addition, the amount of intraoperative blood loss was significantly larger in high BMI patients (WMD: 23.43, 95%CI: 20.05-26.81, P < 0.001; I2 = 40.3%). Compared with non-high BMI patients, overweight and obese patients had a higher risk of postoperative complications (RR:1.26, 95%CI: 1.11-1.43, P < 0.001; I2 = 39.1%), especially for wound infection (RR:1.62, 95%CI: 1.15-2.29, P < 0.01; I2 = 18.8%) and postoperative ileus (RR:1.80, 95% CI: 1.05-3.09, P < 0.05; I2 = 0%). However, there was no significant difference between two patient groups for postoperative recovery, major surgery-related complications (eg: anastomotic leakage, pancreatic fistula and intra-abdominal bleeding) and postoperative mortality. Despite increased technical challenge and risk of postoperative complications, the majority of these complications may be minor and cured. Laparoscopic gastrectomy for GC was a feasible and safe procedure even for high BMI patients.

Abstract
ObjectivesTo determine if linear measurements of adiposity from pre-operative imaging can improve anticipation of surgical difficulty among endometrial cancer patients.MethodsEighty patients with newly diagnosed endometrial cancer were enrolled. Routine pre-operative imaging (MRI or CT) was performed. Radiologic linear measurements of the following were obtained: anterior-to-posterior skin distance; anterior skin to anterior edge of L5 distance (total anterior); anterior peritoneum to anterior edge of L5 distance (visceral obesity); and posterior edge of L5 to posterior skin distance (total posterior). Surgeons completed questionnaires quantifying preoperative anticipated operative difficulty and postoperative reported operative difficulty. The primary objective was to assess for a correlation between linear measurements of visceral fat and reported operative difficulty.ResultsSeventy-nine patients had questionnaires completed, preoperative imaging obtained, and surgery performed. Univariate analysis showed all four linear measurements, body mass index, weight, and anticipated operative difficulty were associated with increased reported operative difficulty (P< 0.05). Multivariate analysis demonstrated that body mass index and linear measurements visceral obesity and total posterior were independently associated with increased reported operative difficulty (P< 0.05). Compared with body mass index, the visceral obesity measurement was more sensitive and specific for predicting increased reported operative difficulty (visceral obesity; sensitivity 54%, specificity 91 %; body mass index; sensitivity 38%, specificity 89%). A difficulty risk model combining body mass index, visceral obesity, and total posterior demonstrated better predictive performance than any individual preoperative variable.ConclusionsSimple linear measurements of visceral fat obtained from preoperative imaging are more predictive than body mass index alone in anticipating surgeon-reported operative difficulty. These easily obtained measurements may assist in preoperative decision making in this challenging patient population.

Abstract
INTRODUCTION There has recently been increased interest in the assessment of body composition in patients with gastric cancer for the purpose of prognostication. This systematic review and meta-analysis aim to evaluate the current literature on body composition assessment in patients with gastric cancer and its impact on peri-operative outcomes. METHODS A systematic literature search was conducted for studies reporting assessment of body composition in patients with gastric cancers. Meta-analysis of postoperative outcomes (overall and major complications, anastomotic leaks, pulmonary complications) and survival was performed using random effects models. RESULTS Thirty-nine studies reported the assessment of body composition in 8402 patients. Methods used to assess body composition in patients with gastric cancers were computerized tomography (n = 26), bioelectrical impedance analysis (n = 9), and dual-energy-X-ray-absorptiometry (n = 3). Only 21 studies reported the impact of pre-operative sarcopenia on post-operative outcomes. Sarcopenic patients have significantly higher rates of postoperative major complications (n = 12, OR 1.67, CI95% 1.14-2.46, p = 0.009), and pulmonary (n = 8, OR 4.01, CI95% 2.23-7.21, p < 0.001) complications after gastrectomy. Meta-analysis of nine studies reporting overall survival after gastrectomy identified significantly worse survival in patients with pre-operative sarcopenia (HR 2.12, CI95% 1.89-2.38, p < 0.001). CONCLUSIONS Assessment of body composition has the potential to become a clinically useful tool that could support decision-making in patients with gastric cancer. However, variation in methods of assessing and reporting body composition in this patient group limits assessment of current post-operative outcomes.

Impact of intra-peritoneal fat distribution on intra-operative bleeding volume with D2 lymphadenectomy in Chinese patients with gastric cancer. Asian J Surg 2018; 42:768-774. [PMID: 30573172 DOI: 10.1016/j.asjsur.2018.11.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2018] [Revised: 11/20/2018] [Accepted: 11/27/2018] [Indexed: 01/15/2023] Open
Abstract
OBJECTIVE To explore the quantitative measurements and evaluation of intra-peritoneal fat distribution by MDCT and its significance in predicting intra-operative bleeding volume during D2 lymphadenectomy in gastric cancer (GC) patients. METHODS From June 2016 to September 2017, GC patients scheduled for open gastrectomy with D2 lymph-node dissection were enrolled. According to the BMI, the subjects were then classified as normal BMI(BMI<25 kg/m2); overweight (BMI = 25-30 kg/m2) and obese (BMI≥30 kg/m2). According to the intraoperative blood loss (IBL), the patients were further separated into high IBL (IBL; ≥ 300 ml) or low IBL (<300 ml). Clinicopathological parameters between the groups were statistically compared and univariate and multivariate analysis were used to identify predictive factors such as intra-peritoneal fat areas (IFA) and intra-peritoneal fat areas ratio (IFAR) for high IBL. RESULTS A total of 226 patients were included in the study where 53 patients underwent distal while 173 underwent total gastrectomy. According to the BMI classification, there were 25 normal BMI, 108 overweight and 25 obese subjects. According to the IBL, there were 98 high IBL and 128 low IBL subjects. IFA and IFAR were significantly greater in the high IBL group than in the low IBL group. There was no significant difference in any other clinicopathological factors between the high IBL group and the low IBL group. Multivariate analysis revealed that high IFA and IFAR independently predicted high IBL. CONCLUSION The use of MDCT to evaluate the precise distribution of abdominal fat during preoperative examination can prompt surgeons to develop techniques to decrease intraoperative bleeding in obese patients. Nevertheless, it is yet necessary to be surgically more meticulous when dealing with patients with high IFA or high IFA/IFAR in order to improve the outcome of D2 gastrectomy.

Abstract
PURPOSE Many studies have demonstrated the advantage of maintaining intraoperative deep neuromuscular block (NMB) with sugammadex. This trial is designed to evaluate the impact of muscle relaxation during laparoscopic subtotal gastrectomy on the oncological benefits, particularly in obese patients with gastric cancer. MATERIALS AND METHODS This is a double-blind, randomized controlled multicenter prospective trial. Patients with clinical stage I-II gastric cancer with a body mass index of 25 and over, who undergo laparoscopic subtotal gastrectomy will be eligible for trial inclusion. The patients will be randomized into a deep NMB group or a moderate NMB group with a 1:1 ratio. A total of 196 patients (98 per group) are required. The primary endpoint is the number of harvested lymph nodes, which is a critical index of the quality of surgery in gastric cancer treatment. The secondary endpoints are surgeon's surgical condition score, patient's sedation score, and surgical outcomes including peak inspiratory pressure, operation time, postoperative pain, and morbidity. DISCUSSION This is the first study that compares deep NMB with moderate NMB during laparoscopic gastrectomy in obese patients with gastric cancer. We hope to show the oncologic benefits of deep NMB compared with moderate NMB during subtotal gastrectomy. TRIAL REGISTRATION NUMBER ClinicalTrials.gov (NCT03196791), date of registration: October 10, 2017.

Prediction of the Risk of Laparoscopy-Assisted Gastrectomy by Comparing Visceral Fat Area and Body Mass Index. Gastroenterol Res Pract 2018; 2018:1359626. [PMID: 30302088 PMCID: PMC6158961 DOI: 10.1155/2018/1359626] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2017] [Revised: 06/09/2018] [Accepted: 08/01/2018] [Indexed: 12/19/2022] Open
Abstract
Propose The purpose of this study was to compare the accuracy of visceral fat area (VFA) and body mass index (BMI) in predicting the risk of laparoscopic-assisted gastrectomy. Methods Clinicopathological and imaging data of 133 patients who underwent laparoscopy-assisted gastrectomy were recorded, including 17 cases of conversion to open surgery. The remaining 116 patients were retrospectively analyzed after we excluded 17 patients who had been transferred to laparotomy. The patients were divided into two groups according to BMI (≤25 kg/m2: BMI-L group; >25 kg/m2: BMI-H group) and VFA (≤100 cm2: VFA-L group; >100 cm2: VFA-H group). Clinical outcomes were compared between the BMI and VFA subgroups. Results There were no differences in intraoperative blood loss and the number of harvested lymph nodes between low and high patients defined by BMI and VFA (p > 0.050). However, in the comparison of patients who underwent laparoscopic resection only, it was found that the operation time and intraoperative blood loss of the VFA-H group were more than those of the VFA-L group (p < 0.050). Compared to the VFA-L group, the VFA-H group had later first exhaust time (p = 0.018), more complications (p < 0.001), and longer hospital stays (p = 0.049). However, no similar conclusion was obtained in the BMI group (p > 0.050). Conclusion This study demonstrates that VFA better evaluates the difficulty of laparoscopy-assisted gastrectomy and the risk of postoperative complications than BMI.

Body Mass Index and Clinical Outcomes from Endoscopic Submucosal Dissection of Gastric Neoplasia. Dig Dis Sci 2017; 62:1657-1665.

Abstract
BACKGROUND AND AIM Association between obesity and endoscopic resection outcomes has not been investigated. We sought to determine the clinical impact of obesity in patients who underwent endoscopic submucosal dissection (ESD) for gastric neoplasia. METHODS A total of 1571 consecutive patients with gastric neoplasia who underwent ESD between December 2010 and March 2016 were enrolled in this study. We retrospectively analyzed 1181 cases that were divided into three groups based upon body mass index (BMI, kg/m2) according to the criteria for Asia-Pacific populations: normal (<23, n = 411), overweight (≥23 and <25, n = 312), and obese (≥25, n = 458). Demographics, endoscopic findings, pathologic results, and clinical outcomes were analyzed. RESULTS No significant differences were observed between the three BMI groups in the following measures: the en-bloc resection rate, the complete resection rate, lymphovascular involvement or submucosal invasion of tumor cells, and adverse events. However, when comparing the obese and overweight groups with the normal group, mean procedure time was longer (P = 0.001) and the percentage of cases requiring more than 30 min, which was the overall mean procedure time, was greater (60.7, 53.2, and 50.1%, respectively; P = 0.006). The significantly associated factors with procedure durations longer than 30 min were obesity, longitudinal and circumferential location, large resection size (≥4 cm), cancer pathology, and submucosal layer invasion. In multivariate analyses, obesity was an independent predictor of long procedure time for gastric ESD. CONCLUSION Being obese or overweight did not directly affect clinical outcomes in gastric ESD. However, obesity was significantly associated with long procedure time. Our results suggest that gastric ESD can be performed safely and effectively in obese patients.

Influence of Visceral Fat on Early Postoperative Outcomes After Distal and Total Gastrectomy for Gastric Cancer. Int Surg 2017.

Abstract
We studied the influence of visceral fat area (VFA) on early postoperative outcomes separately after distal and total gastrectomy. The influence of obesity on outcomes might differ between distal and total gastrectomy, but few studies have directly compared the effects of VFA on early postoperative results between these 2 procedures. We reviewed clinical records of 124 patients with gastric cancer undergoing curative distal or total gastrectomy. Patients were classified into 2 groups: low (<100 cm2) or high (≥100 cm2) VFA. Patient characteristics and early postoperative outcomes were compared between 2 groups separately in distal or total gastrectomy. There were 77 and 47 patients who underwent distal and total gastrectomy, respectively. After distal gastrectomy, operation time (268 ± 44 versus 239 ± 39 minutes, P < 0.05) as well as blood loss (351 ± 231 versus 239 ± 147 mL, P < 0.05) was increased in the high VFA group (N = 32) compared to the low VFA group (N = 45), but morbidity rates did not differ between the 2 groups (50% versus 36%). After total gastrectomy; operation time (285 ± 42 versus 260 ± 53 minutes, P < 0.05); blood loss (427 ± 326 versus 280 ± 179 mL, P < 0.05); rate of morbidity (56% versus 24%, P < 0.05); and intra-abdominal infection (17% versus 0%, P < 0.05) were increased in the high VFA group (N = 18) compared to the low VFA group (N = 29). These results suggest that postoperative morbidity increases after total gastrectomy but not after distal gastrectomy in patients with excessive visceral fat.

Abstract
BACKGROUND To investigate the impact of biological gender on operative parameters, especially operative time, in laparoscopic partial nephrectomy (LPN) for T1 renal tumor. METHODS One hundred and eleven (28 female and 83 male) patients and 64 (20 female and 44 male) patients with renal tumors suspected to be RCC cT1aN0M0 who underwent retroperitoneal and transperitoneal LPN, respectively, were analyzed. The influence of sex on operative factors including retroperitoneal fat tissue thickness, determined on CT, was analyzed. The correlation between operative time and gender was evaluated by unpaired t-test and linear logistic regression model. RESULTS In both retroperitoneal and transperitoneal LPN, the retroperitoneal fat tissue thickness was greater in men than in women. In retroperitoneal LPN, the operative time was significantly longer in men than in women. In contrast, in transperitoneal LPN, no gender difference was observed in regard to the operative time. In retroperitoneal LPN, linear logistic regression assessment showed that gender, retroperitoneal fat tissue thickness, and tumor size were significantly associated with operative time. Coefficient of determination of the prediction model was 0.317. CONCLUSIONS The operative time of retroperitoneal LPN is significantly correlated with gender, maximum tumor diameter, and retroperitoneal fat tissue thickness. We have developed a prediction model for the operative time of retroperitoneal LPN based on preoperative parameters. Interestingly, in transperitoneal LPN, a gender difference in operative time was not apparent, and also predicting operative time might be difficult.

Abstract
BACKGROUND Preoperative chemoradiation has become a routine modality in the treatment of rectal carcinoma that may impair a patients general condition. In these patients, it is important to identify factors that influence postoperative recovery. Visceral obesity(VO) as a metabolic risk factor was studied in rectal cancer patients receiving preoperative chemoradiation. AIM The impact of VO on post-operative outcome in rectal carcinoma surgery after preoperative chemoradiation was studied. In addition, the effect of chemoradiation on body composition was studied. METHOD The visceral fat area(VFA), total fat area(TFA) and skeletal muscle area(SMA) were measured on cross-sectional CT-slides in 74 patients who underwent rectal cancer surgery after chemoradiation. CT-scans taken before and after chemoradiation were analysed. Associations between VFA, per- and postoperative complications were studied. A VFA of 100 cm(2) and 130 cm(2) was used to differentiate between non-VO and VO. RESULTS Using a VO cut-off point of a VFA of 100 cm(2), the VO patients had more per-operative blood loss(471 mL vs 271 mL p = 0.020), a higher complication rate(10% vs 49% p = 0.001), more ileus(2% vs 28% p = 0.027) and a longer length of stay(9.7days vs 13days p = 0.027). When a VFA of 130 cm(2) was used, VO patients showed more complications(17% vs 55%, p = 0.001) and ileus(10% vs 32% p = 0.017). During chemoradiation the SMA increased(Mean difference: 2.2 cm(2) p = 0.024), while the VFA showed no change. CONCLUSION It appears that VO is associated with co-morbidity and poor outcome in rectal cancer patients. Using different cutoff values for VO different associations with outcome were found. SMA increased during chemoradiation, a phenomenon that remains to be explained.

Robot-assisted gastrectomy for early gastric cancer: is it beneficial in viscerally obese patients compared to laparoscopic gastrectomy? World J Surg 2016; 39:1789-97.

Abstract
BACKGROUND The adoption of robotic systems for gastric cancer surgery has been proven feasible and safe; however, a benefit over the laparoscopic approach has not yet been well-documented. We aimed to investigate the surgical outcomes of robotic versus laparoscopic gastrectomy for gastric cancer, according to the extent of surgery and patients' obesity status. METHODS Between January 2009 and July 2011, 770 patients were enrolled in this retrospective analysis. All had stage IA/IB gastric cancer preoperatively and underwent either laparoscopic (n = 622) or robotic (n = 148) gastrectomy. Patients were classified into obese and non-obese groups on the basis of visceral fat area (VFA). The extent of surgery was defined by whether patients underwent distal or total gastrectomy. RESULTS The surgical outcomes following distal gastrectomy were similar between the robotic and laparoscopic groups regardless of the obesity status. After total gastrectomy, the number of total and N2-area lymph nodes were significantly higher in the robotic group than in the laparoscopic group in non-obese patients with VFA < 100 cm(2) (total, 38.8 vs. 46.5; p = 0.018; N2 area, 9.0 vs. 12.4; p = 0.041), but no significant differences were observed in obese population. Robotic group developed less severe complications after total gastrectomy compared to laparoscopic group in non-obese patients (p = 0.036). CONCLUSION Robotic assistance did not improve surgical outcomes over the laparoscopic approach in obese patients undergoing distal gastrectomy. However, non-obese patients with low VFA may benefit from robotic assistance during total gastrectomy in terms of radical D2 lymphadenectomy with fewer serious complications.

Abstract
AIM: To evaluate the implementation of a clinical pathway and identify clinical factors affecting the clinical pathway for laparoscopic gastrectomy.
METHODS: A standardized clinical pathway for gastric cancer (GC) patients was developed in 2001 by the GC surgery team at the Asan Medical Center. We reviewed the collected data of 4800 consecutive patients treated using the clinical pathway following laparoscopic gastrectomy with lymph node dissection for GC involving intracorporeal and extracorporeal anastomosis. The patients were treated between August 2004 and October 2013 in a single institution. To evaluate the rate of completion and risk factors affecting dropout from the clinical pathway, we used a multivariate logistic regression analysis.
RESULTS: The overall completion rate of the clinical pathway for laparoscopic gastrectomy was 84.1% (n = 4038). In the comparison between groups of intracorporeal anastomosis and extracorporeal anastomosis patients, the completion rates were 83.88% (n = 1740) and 84.36% (n = 2071), respectively, showing no statistically significant difference. The main reasons for dropping out were postoperative complications (n = 463, 9.7%) and the need for patient observation (n = 299, 6.2%). Among the discharged patients treated using the clinical pathway, the number of patients who were readmitted within 30 d due to postoperative complications was 54 (1.1%). In a multivariate analysis, the intraoperative events (OR = 2.558) were the most predictable risk factors for dropping out of the clinical pathway. Additionally, being male (OR = 1.459), advanced age (OR = 1.727), total gastrectomy (OR = 2.444), combined operation (OR = 1.731), and ASA score (OR = 1.889) were significant risk factors affecting the dropout rate from the clinical pathway.
CONCLUSION: Laparoscopic gastrectomy appears to be a good indication for the application of a clinical pathway. For successful application, patients with risk factors should be managed carefully.

Abstract
PURPOSE Obesity is associated with morbidity following gastric cancer surgery, but whether obesity influences morbidity after laparoscopic gastrectomy (LG) remains controversial. The present study evaluated whether body mass index (BMI) and visceral fat area (VFA) predict postoperative complications. MATERIALS AND METHODS A total of 217 consecutive patients who had undergone LG for gastric cancer between May 2003 and December 2005 were included in the present study. We divided the patients into two groups ('before learning curve' and 'after learning curve') based on the learning curve effect of the surgeon. Each of these groups was sub-classified according to BMI (<25 kg/m(2) and ≥25 kg/m(2)) and VFA (<100 cm(2) and ≥100 cm(2)). Surgical outcomes, including operative time, quantity of blood loss, and postoperative complications, were compared between BMI and VFA subgroups. RESULTS The mean operative time, length of hospital stay, and complication rate were significantly higher in the before learning curve group than in the after learning curve group. In the subgroup analysis, complication rate and length of hospital stay did not differ according to BMI or VFA; however, for the before learning curve group, mean operative time and blood loss were significantly higher in the high VFA subgroup than in the low VFA subgroup (P=0.047 and P=0.028, respectively). CONCLUSIONS VFA may be a better predictive marker than BMI for selecting candidates for LG, which may help to get a better surgical outcome for inexperienced surgeons.

Abstract
BACKGROUND Visceral obesity may affect outcome after colorectal surgery. The visceral fat area as determined by CT scanning is considered the standard in the detection of visceral obesity. METHOD A systematic review was performed of trials investigating the effect of visceral obesity on outcomes of patients with colorectal cancer with no radiotherapy or chemotherapy and measured by CT scanning. The main endpoints were primary hospital stay, morbidity, operative time and blood loss. Quality assessment and data extraction were performed independently by two observers. RESULTS Seven studies were eligible for analysis, including 1230 patients. Primary hospital stay (weighted mean difference 1.16 days, 95% CI 0.0.05 to 2.28 days, p = 0.04), morbidity rates (RR 0.15, 95% CI 0.10 to 0.21, p < 0.00001) and operative time (weighted mean difference 20.47 min, 95% CI 12.76 to 28.17 min, p < 0.00001) were significantly higher for visceral obese patients. No difference was found in blood loss. CONCLUSION Visceral obesity leads to a longer hospital stay, higher morbidity and longer operative time after elective colon surgery. These findings show that the preoperative CT scan for detecting disseminated disease can be used to assess visceral obesity and helps in risk profiling patients undergoing elective colon surgery.

Abstract
PURPOSE The aim of this study was to investigate the impact of the visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery on operative outcomes such as number of retrieved lymph nodes (LNs) and operative time. METHODS We retrospectively reviewed the medical records and the CT scans of 597 patients with gastric cancer who underwent laparoscopy assisted distal gastrectomy (LADG) with partial omentectomy and LN dissection (>D1 plus beta). Patients were stratified by gender, VFA, and body mass index (BMI), and the clinicopathologic characteristics and operative outcomes were evaluated. Multiple linear regression analysis was used to assess the effects of VFA and BMI on the number of retrieved LNs and operative time in male and female patients. RESULTS The mean number of retrieved LNs was significantly decreased for both male and female patients with high VFA. The operative time was significantly longer for both male and female patients with high VFA. The number of retrieved LNs had a statistically significant negative correlation with VFA in both men and women, but not with BMI. The operative time had a statistically significant positive correlation with VFA in men, whereas the operative time had a statistically significant positive correlation with BMI in women. CONCLUSION The preoperative VFA of male patients with gastric cancer who undergo LADG may affect the number of retrieved LNs and operative time. VFA was more useful than BMI for predicting outcomes of LADG.

J Cancer 2015; 6:120-7. [PMID: 25561976 PMCID: PMC4280394 DOI: 10.7150/jca.10639] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2014] [Accepted: 11/15/2014] [Indexed: 12/22/2022] Open
Abstract
Three-step hand-assisted laparoscopic D2 radical gastrectomy (HALG) is a modified surgical procedure that has achieved satisfactory results for obese patients in our surgical center. To fully elucidate the advantages of this procedure, in this study, comprehensive and in-depth comparative analyses were performed to assess clinical data from obese gastric cancer patients who underwent HALG, laparoscopic-assisted D2 radical gastrectomy (LAG), and open D2 radical gastrectomy (OG) in our surgical center during a specific time period. For the 3 groups, incision length was 1.25 cm longer for the HALG group than for the LAG group but was significantly shorter for the HALG group than for the OG group (P =0.00). The rate of conversion to laparotomy , the pneumoperitoneum time and the number of recovered lymph nodes were significantly better for the HALG group than for the LAG group (P <0.05). The pain score at day 2 after surgery, intestinal function recovery time, and duration of postoperative hospital stay were not significantly different for the HALG and LAG groups ( P >0.05) but were significantly better for the HALG group than for the OG group (P <0.05). There were significantly fewer postoperative complications for the HALG group than for the LAG and OG groups (P =0.049). According to the results, the “three-step HALG method” incorporates both the thoroughness of the radical OG approach and the minimal invasiveness of the LAG approach for obese patients. Thus, the HALG approach is a relatively safe and extremely feasible surgical procedure for the treatment of these patients.

Laparoscopic gastrectomy versus open gastrectomy for gastric cancer in patients with body mass index of 30 kg/m2 or more. Surg Endosc 2014; 29:2126-32. [PMID: 25480601 DOI: 10.1007/s00464-014-3953-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2014] [Accepted: 10/25/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND High body mass index (BMI) and high visceral fat area (VFA) are known to be a preoperative risk factor for laparoscopic gastrectomy (LG) for gastric cancer. However, the impact of obesity on LG still remains controversial. In the present study, we compared the operative outcomes of LG with those of OG in patients with BMI of 30 kg/m(2) or more. METHODS Seventy-seven patients who underwent distal or total gastrectomy for gastric cancer were enrolled. The patients were divided into two groups by approach method; an OG group (n = 19) and a LG group (n = 62). Aquarius iNtuition(®) program was used to measure VFA. The operation time, estimated blood loss, complication rate, the number of retrieved lymph nodes, and patient survival were compared between two groups. RESULTS The mean BMI and VFA were 31.6 kg/m(2) and 195.3 cm(2). The complication rate was 42.1 % in OG group and 14.5 % in LG group, respectively (P = 0.010). LG group showed less estimated blood loss (P = 0.030) and fast recovery of bowel movement (P < 0.001). However, there were no significant differences in operation time, the number of retrieved lymph nodes, and the length of hospital stay between two groups. In subgroup analysis, there was significant correlation between estimated blood loss and VFA (R (2) = 0.113, P = 0.014), but there was no correlation between operation time and VFA (R(2) = 0.002, P = 0.734). In stage I, the 5-year survival was not different between two groups (P = 0.220). CONCLUSION LG showed better operative outcomes compared with OG, in terms of less estimated blood loss, fast recovery of bowel movement, and low complication rate, in patients with BMI of ≥ 30 kg/m(2) or more.

Abstract
BACKGROUND AND PURPOSE Obese patients undergoing surgical procedures are at increased risk for perioperative morbidity. The purpose of this study is to determine whether there is an association with body mass index (BMI), clinicopathologic features, and perioperative outcomes and complications in patients undergoing robot-assisted laparoscopic partial nephrectomy (RPN). PATIENTS AND METHODS Medical records of 283 patients who underwent RPN between 2007 and 2012 were reviewed from an Institutional Review Board approved database. We analyzed the association of perioperative outcomes and complications of the surgery with BMI and clinicopathologic features using analysis of variance, Kruskal-Wallis test, t test and chi-square-test. Eventually, independent factors associated with perioperative outcomes and complications were studied using univariate and multivariate regression analysis. RESULTS Perioperative outcomes including estimated blood loss (EBL), length of hospital stay (LOS) and operative time (OT) were significantly associated with BMI (P=0.002, P=0.009 and P=0.002, respectively). Warm ischemia time (WIT), perioperative complications, and change in glomerular filtration rate (GFR) before and after surgery were not associated with BMI (P=0.459, P=0.86 and P=0.773). In multivariate analysis, BMI, tumor size≥4 cm, and collecting system invasion were independently associated with EBL and OT. Increased LOS was independently associated with BMI and tumor size ≥4 cm. CONCLUSIONS Increasing BMI was not associated with a significant increase in perioperative complications, WIT, or change in GFR in patients undergoing RPN at a high-volume tertiary medical center. Collecting system invasion or tumor size ≥4 cm and BMI were independently associated with higher EBL, LOS, and OT, however.
