[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. Nutrients 2022; 14:nu14204236. [PMID: 36296920 PMCID: PMC9607456 DOI: 10.3390/nu14204236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/27/2022] [Accepted: 10/08/2022] [Indexed: 11/24/2022] Open
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.

An advanced bipolar device helps reduce the rate of postoperative pancreatic fistula in laparoscopic gastrectomy for gastric cancer patients: a propensity score-matched analysis. Langenbecks Arch Surg 2022; 407:3479-3486. [PMID: 36181517 DOI: 10.1007/s00423-022-02692-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 09/15/2022] [Indexed: 10/07/2022]
Abstract
BACKGROUND Advanced bipolar devices (ABD; e.g., LigaSure™) have a lower blade temperature than ultrasonically activated devices (USAD; e.g., Harmonic® and Sonicision™) during activation, potentially enabling accurate lymph node dissection with less risk of postoperative pancreatic fistula (POPF) due to pancreatic thermal injury in laparoscopic gastrectomy. Therefore, we compared the efficacy and safety of ABD and USAD in laparoscopic gastrectomy for gastric cancer patients. METHODS A retrospective cohort study was conducted on patients who underwent laparoscopic distal gastrectomy (LDG) between August 2008 and September 2020. A total of 371 patients were enrolled, and short-term surgical outcomes, including the incidence of ISGPF grades B and C POPF, were compared between ABD and USAD. The risk factors for POPF in LDG were investigated by univariate and multivariate analyses. RESULTS A propensity score-matching algorithm was used to select 120 patients for each group. The POPF rate was significantly lower (0.8 vs. 9.2%, p < 0.001), the morbidity rate was lower (13.3 vs. 28.3%, p < 0.001), the length of postoperative hospitalization was shorter (14 vs. 19 days, p < 0.001), and the lymph node retrieval rate was higher (34 vs. 26, p < 0.001) with an ABD than with a USAD. There were no mortalities in either group. A multivariate analysis showed that a USAD was the only independent risk factor with a considerably high odds ratio for the occurrence of POPF (USAD/ABD, odds ratio 8.38, p = 0.0466). CONCLUSION An ABD may improve the safety of laparoscopic gastrectomy for gastric cancer patients.

Incidence and risk factors for postoperative pancreatic fistula in 2089 patients treated by radical gastrectomy: A prospective multicenter cohort study in China. Int J Surg 2022; 98:106219.

Abstract
OBJECTIVE To determine the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) following radical gastrectomy and to identify independent risk factors of CR-POPF. BACKGROUND CR-POPF and its sequelae are potential complications following radical gastrectomy. The reported incidence of CR-POPF was quite different across various regions, and no consensus was reached. METHODS Between December 2017 to November 2018, patients who underwent radical gastrectomy from 22 centers across 13 regions in China were prospectively recruited. The primary endpoint was the occurrence of CR-POPF, defined by the International Study Group of Pancreatic Fistula (ISGPF) in 2016. Clinically relevant change and short-term outcomes were recorded to diagnose and grade the POPF. Multivariate regression analyses were performed to identify independent risk factors of clinically relevant postoperative pancreatic fistula (CR-POPF). RESULTS A total of 2089 cases were analyzed. The incidence of biochemical leakage (BL) and CR-POPF were 19.6% and 1.1% respectively. All CR-POPF patients recovered well after appropriate treatment and no Grade C POPF were recorded. Logistic regression analysis showed pTNM III (OR, 2.940; 95% CI 1.180-7.325; P = 0.021) and LigaSure usage (OR, 6.618; 95% CI 1.847-23.707; P = 0.004) were independent risk factors of CR-POPF. LigaSure usage (OR, 4.817; 95% CI 1.184-19.598; P = 0.028), the drain amylase content (D-AMY) on postoperative day 3 (POD3) ≥5 times the upper limit of normal amylase (OR, 3.476; 95% CI 1.240-9.744; P = 0.018) and open surgery (OR, 2.463; 95% CI 1.003-6.050; P = 0.049) were independent predictors for identifying CR-POPF from BL. CONCLUSION In rich-experienced gastric cancer centers, there is high prevalence of BL secondary to radical gastrectomy without clinical impact. Fewer patients suffered Grade B POPF, and Grade C POPF was less common. The patients with pTNM III or LigaSure usage were prone to suffer CR-POPF. Surgery procedure, LigaSure usage combined with D-AMY measurement on POD3 are promising for early identification of CR-POPF.

Abstract
Purpose Incidence, risk factors, and clinical consequences of pancreatic fistula (POPF) after D1+/D2 radical gastrectomy have not been well investigated in Western patients, particularly those from Eastern Europe. Materials and Methods A total of 358 D1+/D2 radical gastrectomies were performed by surgeons with high caseloads in a single surgical center from 2002 to 2017. A retrospective analysis of data that were prospectively gathered in an electronic database was performed. POPF was defined and graded according to the International Study Group for Pancreatic Surgery (ISGPS) criteria. Uni- and multivariate analyses were performed to identify potential predictors of POPF. Additionally, the impact of POPF on early complications and long-term outcomes were investigated. Results POPF was observed in 20 patients (5.6%), according to the updated ISGPS grading system. Cardiovascular comorbidities emerged as the single independent predictor of POPF formation (risk ratio, 3.051; 95% confidence interval, 1.161–8.019; P=0.024). POPF occurrence was associated with statistically significant increased rates of postoperative hemorrhage requiring re-laparotomy (P=0.029), anastomotic leak (P=0.002), 90-day mortality (P=0.036), and prolonged hospital stay (P<0.001). The long-term survival of patients with gastric adenocarcinoma was not affected by POPF (P=0.661). Conclusions In this large series of Eastern European patients, the clinically relevant rate of POPF after D1+/D2 radical gastrectomy was low. The presence of co-existing cardiovascular disease favored the occurrence of POPF and was associated with an increased risk of postoperative bleeding, anastomotic leak, 90-day mortality, and prolonged hospital stay. POPF was not found to affect the long-term survival of patients with gastric adenocarcinoma.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is one of the most severe complications after cephalic pancreaticoduodenectomy, with mortality as high as 30%. Risk scores may help predict the risk of POPF. Multiple external validations substantially improve generalized clinical acceptability of a scoring system. AIM The aim of this study was to externally validate previously described fistula risk score in the prediction of clinically relevant POPF. METHODS All patients who underwent pancreaticoduodenectomy for any indication during a 5-year period were prospectively analyzed. A total of 132 patients were analyzed. RESULTS Of the 132 patients, 44 (33.3%) developed pancreatic fistula, including 12.9% biochemical leaks, 7.6% grade B fistula, and 12.9% grade C fistula. Cut-off point of 4.5 was determined to best separate patients who developed clinically relevant POPF with area under curve of 78% (p = .00003). Sensitivity and specificity for the prediction of clinically relevant POPF with the cut-off value of 4.5 was 70.4 and 74.3%, respectively. Positive predictive value with cut-off value 4.5 was 57.8%, and negative predictive value was 83.4%. CONCLUSION Fistula risk score identified low risk patients with false negative rate of 16.6%. Further external validation studies on large cohorts of patients and with wide case-mix may enable additional refinements of the score model.

Abstract
Postoperative pancreatic fistula is one of the most severe complications after gastric cancer surgery, and can cause critical patient conditions leading to surgery-related death. Fortunately, the incidence of postoperative pancreatic fistula after gastrectomy seems to be decreasing with changes in operative procedures. The rate was reported at about 30% after open gastrectomy with Appleby's method in 1997, but lately has improved below 1% for robotic gastrectomy in 2019. For the diagnosis of postoperative pancreatic fistula, drain amylase concentration has been demonstrated to be beneficial and some reports have proposed the optimal cut-off values of drain amylase to predict major postoperative pancreatic fistula. There have been many reports identifying risk factors for postoperative pancreatic fistula, including overweight patients, pancreatic anatomy, blunt trauma from compression of the pancreas, and thermal injuries caused by the continuous use of energy devices. And importantly, laparoscopic gastrectomy has been shown to be more often associated with postoperative pancreatic fistula than open gastrectomy in the prospective national clinical database in Japan. Hence, further sophistication of surgical techniques to reduce pancreas compression would have great promise in reducing postoperative pancreatic fistula after laparoscopic gastrectomy.

Abstract
Objective To analyse potential risk factors for postoperative pancreatic fistula (POPF). Methods A retrospective study on risk factors for POPF was conducted in patients undergoing laparoscopic pancreatoduodenectomy. Basic characteristics, and preoperative, intraoperative and postoperative patient data were collected and analysed. Results A total of 268 patients were enrolled in this study, including 54 patients with POPF following surgery (POPF incidence, 20.15%). Univariate analysis indicated that patient’s age, body mass index (BMI), preoperative bilirubin level, pancreas texture, and drainage fluid amylase level on day 1 following surgery were associated with POPF. Multiple logistic regression analysis indicated that preoperative bilirubin level ≥170 µmol/l, soft pancreas texture, BMI ≥25, and age ≥65 years were independent risk factors associated with POPF. Conclusions For patients with preoperative bilirubin level ≥170 µmol/l, soft pancreas texture, BMI ≥25 and age ≥65 years, clinically relevant measures should be taken as early as possible for the prophylaxis of POPF.

Abstract
BACKGROUND Suprapancreatic lymphadenectomy is the essence of D2 radical gastric cancer surgery. The present study aimed to describe clockwise modularized laparoscopic lymphadenectomy in the suprapancreatic area. METHODS The data from gastric cancer patients who underwent surgical treatment from September 2016 to December 2018 were collected. Patients were divided into clockwise modularized lymphadenectomy (CML) and traditional open gastrectomy (OG) groups according to the surgical treatment strategy. The propensity score matching method was utilized to balance the baseline characteristics between the two groups. RESULTS Finally, 551 gastric cancer patients were included in the present study. Following propensity score matching, 106 pairs of patients in the CML group and OG group were included in the final analysis. The CML group had more total examined lymph nodes (36, IQR 28-44.74 vs. 29, IQR 29-39.5, p = 0.002) and no. 9 station nodes (2, IQR 1-5 vs. 2, IQR 1-3, p = 0.007) than the OG group. There was less intraoperative blood loss (30, IQR 20-80 ml vs. 80, IQR 50-80 ml, p < 0.001) and a longer surgical duration (262.5 min, IQR 220-303.25 min vs. 232, IQR 220-255 min, p < 0.001) in the CML group than in the OG group. The incidence of postoperative complications (19.8% vs. 16.0%, p = 0.591) and postoperative hospital stay (8, IQR 7-9 days vs. 8, IQR 7-9 days, p = 0.452) were comparable between the CML and OG groups. CONCLUSION Laparoscopic lymphadenectomy for gastric cancer surgery is technically demanding. Clockwise modularized laparoscopic lymphadenectomy in the suprapancreatic area can attain similar effects as traditional open surgery and without an increase in postoperative adverse events.

Abstract
BACKGROUND There are numerous studies on postoperative pancreatic fistula (POPF) in pancreatic surgery but few studies on POPF in extrahepatic bile duct resection with or without hepatectomy for perihilar cholangiocarcinoma (PHCC). The aim of this study is to investigate the incidence of and risk factors for POPF in this challenging surgery. METHODS All consecutive patients who underwent surgical resection for presumed PHCC between January 2008 and December 2017 were retrospectively reviewed, with special attention paid to POPF. RESULTS Among 416 patients, 90 patients showed a drain amylase level of > 3 times the normal limit on day 3 or after. The severity of POPF was biochemical leakage in 46 patients and grade B in 44 patients. No patient had grade C POPF; thus, the incidence of clinically relevant POPF was 10.6% (44/416). The resection line of the common bile duct was closely associated with POPF; 23 (27.7%) of the 83 patients who underwent intrapancreatic resection of the common bile duct developed POPF. The occurrence of intra-abdominal abscess and liver failure was significantly higher in patients with POPF, but the 90-day mortality was similar. The multivariate analysis identified a body mass index of ≥ 22 and intrapancreatic bile duct resection as independent risk factors for POPF. CONCLUSIONS POPF occurs in approximately 10% of patients undergoing resection for PHCC. Careful postoperative management with attention to POPF is required, especially in patients who undergo intrapancreatic resection of the common bile duct and in those with a high body mass index.

Abstract
BACKGROUND Although many methods to prevent the development of postoperative pancreatic fistula (POPF) after gastrectomy have been reported, POPF can only be identified after it has occurred. Various therapeutic measures could be taken if signs of POPF could be detected intraoperatively. METHODS We conducted a prospective study in which we attempted to predict POPF by measuring the intraoperative amylase concentration in the peripancreatic body fluid. To collect the body fluid, three sponges were placed around the pancreas at lymph node station Nos. 6, 8, and 11 during lymphadenectomy. The amylase concentration was measured in the body fluid squeezed from the sponges. We investigated whether the intraoperative body fluid amylase concentration (IBAC) was associated with POPF formation. RESULTS In total, 109 patients were enrolled from February 2016 to March 2018, and we analyzed 81 eligible patients. Clavien-Dindo grade ≥ II POPF occurred in eight patients (9%). The IBAC was significantly higher in sponges No. 6 (P = 0.044) and No. 8 (P = 0.007). The incidence of POPF was predicted by using an IBAC cutoff value for No. 6 (1047 IU/L; sensitivity 87.5%; specificity 65.0%; positive likelihood ratio 2.5) and No. 8 (400 IU/L; sensitivity 87.5%; specificity 68.5%; positive likelihood value 2.8), respectively. The IBAC in sponge No. 11 tended to be higher (P = 0.054). CONCLUSIONS By measuring the IBAC, surgeons might predict POPF easily and noninvasively during surgery. This method is one of the most effective ways to predict POPF intraoperatively.

Abstract
Fatty pancreas is a newly proposed condition which is characterized by fat deposition and steatosis in the pancreas followed by outcome of pancreatic and metabolic complications. It has been found to be correlated with many metabolic disorders and a variety of diseases. Fatty pancreas has been associated with obesity, non-alcoholic fatty liver disease, metabolic syndrome, type 2 diabetes mellitus, acute and chronic pancreatitis, and even pancreatic carcinoma. Therefore, fatty pancreas might not only be an early marker of glucose or lipid metabolism disorders or metabolic syndrome, but also be a predictor of poor outcome of pancreatic related diseases. At present, imaging examination is the main diagnostic method. However, there is currently still a lack of a unified terminology, diagnostic criteria, treatment consensus, and guidelines due to very limited knowledge on this condition. Here we discuss the pathophysiology, pathogenesis, clinical implications, diagnosis, and treatment of fatty pancreas, with an aim to improve the early intervention, treatment, and prognosis prediction of fatty pancreas related metabolic disorders.

Abstract
In recent years, both the actual number of overweight/obese individuals and their proportion of the population have steadily been rising worldwide and obesity-related diseases have become major health concerns. In addition, as obesity is associated with an increased incidence of gastroenterological cancer, the number of obese patients has also been increasing in the field of gastroenterological surgery. While the influence of obesity on gastroenterological surgery has been widely studied, very few reports have focused on individual organs or surgical procedures, using a cross-sectional study design. In the present review, we aimed to summarize the impacts of obesity on surgeries for the esophagus, stomach, colorectum, liver and pancreas. In general, obesity prolongs operative time. As to short-term postoperative outcomes, obesity might be a risk for certain complications, depending on the procedure carried out. In contrast, it is possible that obesity doesn't adversely impact long-term surgical outcomes. The influences of obesity on surgery are made even more complex by various categories of operative outcomes, surgical procedures, and differences in obesity among races. Therefore, it is important to appropriately evaluate perioperative risk factors, including obesity.

Abstract
Abstract Surgical resection represents the mainstay treatment and only potentially curative option for gastric carcinoma, and is increasingly performed laparoscopically. Furthermore, other tumours and selected cases of non-malignant disorders of the stomach may require partial or total gastrectomy. Often performed in elderly patients, gastric resection remains a challenging procedure, with significant morbidity (14–43% complication rate) and non-negligible postoperative mortality (approximately 3%). This paper provides an overview of contemporary surgical techniques for non-bariatric gastric resection, reviews and illustrates the expected postoperative imaging appearances, common and unusual complications after partial and total gastrectomy. Albeit cumbersome or unfeasible in severely ill or uncooperative patients, contrast fluoroscopy remains useful to rapidly check for anastomotic patency and integrity. Currently, emphasis is placed on multidetector CT, which comprehensively visualizes the surgically altered anatomy and consistently detects complications such as anastomotic leaks and fistulas, duodenal stump leakage, afferent loop syndrome, haemorrhages, pancreatic fistulas and porto-mesenteric venous thrombosis. Our aim is to help radiologists become familiar with early postoperative imaging, in order to understand the surgically altered anatomy and to differentiate between expected imaging appearances and abnormal changes heralding iatrogenic complications, thus providing a consistent basis for correct choice between conservative, interventional or surgical treatment. Teaching points • Radical gastrectomy is associated with frequent postoperative morbidity and non-negligible mortality. • In cooperative patients fluoroscopy allows checking for anastomotic patency and leaks. • Multidetector CT with / without oral contrast comprehensively visualizes the operated abdomen. • Awareness of surgically altered anatomy and expected postoperative appearances is warranted. • Main complications include anastomotic and duodenal leaks, haemorrhages and pancreatic fistulas.
