BACKGROUND: China is one of the countries with the highest burdens of stomach cancer. The objective of this study was to analyze long-term trends in the incidence and mortality of stomach cancer in Chinese mainland from 1990 to 2019 and to make projections until 2030. METHODS: Data on stomach cancer were extracted from the Global Burden of Diseases Study 2019. Population data were extracted from the Global Burden of Diseases Study 2019 and World Population Prospects 2019. An age-period-cohort framework and decomposition analysis were used in this study. RESULTS: The net drift for the incidence of stomach cancer was 0.2% (95% confidence interval [CI]: 0, 0.4%) per year for men and -1.8% (95% CI: -2.0%, -1.6%) for women. The net drift for mortality was -1.6% (95% CI: -1.8%, -1.3%) per year for men and -3.3% (95% CI: -3.5%, -3.1%) for women. In the last 10-15 years, the risk of stomach cancer occurrence and death has continued to decline for both sexes. Regarding birth cohorts, although the risk of stomach cancer death decreased in general among women and men born after 1920, the risk of occurrence increased in recent birth cohorts (men born after 1970 and women born after 1985). It is expected that the age-standardized incidence will increase among men and decrease among women, and age-standardized mortality will decrease for both sexes. The largest contributor to the projected increase in incident cases and deaths is population aging, and elderly individuals are projected to have an increased proportion of occurrence and death. CONCLUSIONS In the past three decades, the incidence of stomach cancer among men has increased in Chinese mainland, and this trend is projected to continue. Aging will be the main contributor to future increased stomach cancer occurrence and deaths. To reduce the health impact of stomach cancer, more efforts are needed.

Objective:To evaluate the short-term and long-term efficacy of Heidelberg triangle dissection in surgical treatment for pancreatic head cancer.Methods:The clinicopathological data of 97 patients with pancreatic head cancer who underwent pancreaticoduodenectomy at Cangzhou Central Hospital from Jan 2017 to Jan 2020 were retrospectively analyzed. After propensity score matching, 33 patients were included into the Heidelberg group and 36 patients in the control group.Results:There were no significant difference between Heidelberg group and control group in preoperative general conditions and postoperative major complications, while there were more cases with safe surgical margin > 1 mm (81.8% vs. 58.3%, P=0.034) and a significantly higher total number of lymph node dissection (11.24±2.35 vs. 9.50±2.76, P=0.006). In the survival analysis, the cumulative recurrence rate at 12 months (0.182±0.067 vs. 0.444±0.083, P=0.023) and 18 months (0.424±0.086 vs. 0.667±0.079, P=0.024) were better off in the Heidelberg group, and the local recurrence rate in the Heidelberg group was significantly lower than that in the control group (15.3 % vs. 36.1 %, P=0.037). However, there was no statistical difference in the overall survival time between the two groups. Conclusion:Dissection of Heidelberg triangle in radical resection of pancreatic head cancer reduces tumor local recurrence ,while fails to provide survival benefit.

BACKGROUND: Tracheal, bronchus, and lung cancer (TBL) is a major cause of mortality and top contributor to productivity loss in large emerging economies such as the BRICS (Brazil, Russia, India, China, and South Africa). We examined the time trends of TBL mortality across the BRICS to better understand the disease burden in these countries and inform public health and healthcare resource allocation. METHODS: TBL mortality-related data between 1990 and 2019 were obtained from the Global Burden of Disease Study 2019 and analyzed using age-period-cohort models. Net drift (local drift) was used to describe the expected age-adjusted TBL mortality rate over time overall (each age group); the longitudinal age curve was used to reflect the age effect; the period rate ratios (RRs) were used to reflect the period effect; and the cohort RR was used to reflect the cohort effect. RESULTS: In 2019, there were 958.3 thousand TBL deaths across the BRICS, representing 46.9% of the global TBL deaths. From 1990 to 2019, the age-standardized mortality rate (ASMR) of TBL decreased in Russia, Brazil, and South Africa while increased in China and India, with the largest reduction reported in Russia (-29.6%) and the largest increase in China (+22.4%). India showed an overall increase (+15.7%) in TBL mortality but the mortality risk decreased among individuals born after 1990 (men) and 1995 (women). Although South Africa and Brazil experienced an overall decline in TBL mortality, their recent birth cohorts, such as Brazilian individuals born after 1985 (men) and 1980 (women), and South African men born after 1995, had an increasing TBL mortality risk. China has experienced an overall increase in TBL mortality, with the mortality risk rising among individuals born after 1995 for both men and women. Russia, which had the highest TBL mortality among the BRICS countries in 1990, has demonstrated significant improvement over the past three decades. CONCLUSIONS Over the past 30 years, the BRICS accounted for an increasing proportion of global TBL mortality. TBL mortality increased in older women in all the BRICS countries except Russia. Among the recent birth cohort, the risk of TBL mortality increased in Brazil, China, and South Africa. More effective efforts are needed in the BRICS to reduce the burden of TBL and help achieve the United Nation's Sustainable Development Goals.

Objective:To analyze the common complications of laparoscopic duodenum- preserving pancreatic head resection(LDPPHR).Methods:The clinical data of 32 patients undergoing LDPPHR from Jun 2018 to Jun 2021 in Cangzhou Central Hospital were analyzed retrospectively.Results:LDPPHR was successfully performed in all 32 patients without conversion to open surgery. The incidence of postoperative complications was 21.9% (7/32), 3 cases suffering from sever complications (1 case of long-term postoperative pancreatic fistula, 1 case of obstructive jaundice caused by duodenal papilla stenosis, 1 case of postoperative abdominal bleeding) were cured by laparotomy; 4 cases of minor complications were simple pancreatic fistula, which were cured by prolonging dranage.Conclusions:LDPPHR is technically feasible for isolated noncancerous lesions within pancreatic head and uncinate process,the complications were manageable.Its suggested benefits remain to be established by long term follow-up.

Objective:To investigate the characteristics and risk factors of local recurrence in resected pancreatic cancer.Methods:The clinicopathological data of 190 patients in whom recurrent sites can be identified after radical resection of pancreatic cancer from Sep 2013 to Aug 2020 at the Cangzhou Central Hospital were retrospectively analyzed. The survival time and clinicopathological characteristics of local recurrence were compared with those of other recurrence types. Cox risk regression model was used to analyze the risk factors of local recurrence.Results:The recurrence sites were local (49 cases, 25.8%), liver (53 cases, 27.9%), lung (35 cases, 18.4%), peritoneal (25 cases, 13.2%) and multiple sites (28 cases, 14.7%). Patients mRFS and mOS were 17.8 months and 30.9 months respectively. The clinicopathological features of patients with local recurrence were compared with those of other recurrence types [tumor diameter ( P=0.023), preoperative CA199 level ( P=0.021), peripancreatic nerve plexus invasion ( P=0.031), lymphovascular invasion ( P=0.004), surgical margin state ( P<0.001) and postoperative adjuvant chemotherapy ( P=0.038)]. Tumor diameter ( P=0.018), peripancreatic nerve plexus invasion ( P=0.002) and postoperative adjuvant chemotherapy ( P=0.004) were independent factors for local recurrence in resected pancreatic cancer, and only peripancreatic nerve plexus invasion was not associated with other recurrence types. Conclusions:Local recurrence in resected pancreatic cancer has important impact on the prognosis of patients. Peripancreatic nerve plexus invasion is an independent factor affecting local recurrence.

Objective:To investigate the short-term outcome of Heidelberg triangle dissection in laparoscopic pancreaticoduodenectomy (LPD) for pancreatic cancer.Methods:The clinical data of 84 patients with pancreatic head cancer who underwent LPD from July 2015 to September 2020 in the Department of Hepatobiliary and Pancreatic Surgery of the Cangzhou Central Hospital were retrospectively analyzed. According to the scope of surgical dissection, the patients were divided into the control group ( n=45) and the Heidelberg group ( n=39). In the control group, routine lymph node dissection was performed, and in the Heidelberg group, all blood vessels, lymphatic tissue and nerve tissue in the Heidelberg triangle area were dissected on the basis of routine lymph node dissection. Operation-related indicators (operation duration, intraoperative blood loss, cases of patients with intraoperative blood transfusion, fasting time and hospitalization duration after operation), postoperative complications (pancreatic fistula, biliary fistula, lymphatic fistula, bleeding and delayed gastric emptying) and postoperative pathological parameters (surgical margin, degree of differentiation, tumor size, cases of nerve invasion, number of dissected lymph nodes, lymph node metastasis and TNM stage) were compared between the two groups. Results:Compared with the control group, the operation time of the Heidelberg group was longer [ (334.85±24.95)min vs (305.09±24.54)min], theincidence of lymphatic fistula was higher (15.4% vs 2.2%), the rate of >1 mm at surgical margin was higher (76.9% vs 53.3%), and the total number of lymph nodes dissection was more [ (11.31±2.46) vs (9.49±2.28)]. All the differences between the two groups were statistically significant ( P<0.05). However, there were no significant differences on the intraoperative blood loss, cases of patients with intraoperative blood transfusion, postoperative hospital stay and fasting time, incidence of pancreatic fistula and biliary fistula, bleeding, delayed gastric emptying, degree of differentiation, tumor size, cases of nerve invasion, lymph node metastasis and TNM stage between the two groups. Conclusions:LPD combined with Heidelberg triangle dissection for pancreatic cancer was feasible and safe, which can increase the R 0 resection rate, remove more lymph nodes, reduce the local recurrence of pancreatic cancer and improve the prognosis of patients.

Objective To explore the safety and feasibility of laparoscopic radical resection of Bismuth-type Ⅲb hilar cholangiocarcinoma.Methods The clinical data of 109 patients with Bismuth-type Ⅲ b hilar cholangiocarcinoma in the Department of General Surgery of Cangzhou Central Hospital from Jan 2015 to Feb 2018 were retrospectively analyzed.Among those 17 patients undergoing total laparoscopic surgery were compared with 17 open cases.Results There were significant differences between the laparoscopic group and the control group in operation time [(420.8 ± 136.5) min vs (292.3 ± 65.6) min],total length of incision [(8.2 ± 4.7) cm vs (20.4 ± 5.8) cm],incidence of postoperative complications [29.4％ (5/17) vs 52.9％ (9/17)],postoperative feeding time,postoperative ICU stay and postoperative hospital stay (P ＜ 0.05).There were no significant difference in the amount of bleeding[(325.2 ± 98.7)ml vs(367.4 ±72.9)ml],pathological results,number of lymph node dissection,R0 resection rate and tumor recurrence rate (P ＞ 0.05).Conclusion Total laparoscopic radical resection of Bismuth-type Ⅲ b hilar cholangiocarcinoma is safe,feasible,and has the advantages of minimal invasion and rapid recovery.

Objective to investigate the feasibility of laparoscopic radical resection for hilar cholangiocarcinoma.Methods From June 2016 to June 2018,30 patients with hilar cholangiocarcinoma (HCC) underwent total laparoscopic radical resection.Results Surgery was successfully performed in all cases without conversion,15 cases underwent hilar bile duct resection,and hilar lymph node dissection,14 cases underwent left hemi-hepatectomy and caudate lobectomy,and 1 case underwent extrahepatic bile duct resection.The operation time was 258-336 min,(286.8 ± 18) min,intraoperative bleeding was 60-210 ml (139.7 ±38.0) ml.Postoperative bile fistula occurred in 5 cases,healed conservatively after 5 days,stress ulcer in 1 case,and intestinal anastomotic bleeding in 1 case,were all cured by themselves.Postoperative hospitalization was 7-12 days (mean 8.9 d).After 6-12 months follow-up,3 cases died of recurrent and metastatic cancer after 6 months of operation,27 cases were alive.Conclusion Total laparoscopic radical resection of hilar cholangiocarcinoma is safe and feasible.

Objective: To investigate the effect of end-to-side pancreaticojejunostomy with pocket-insertion on the incidence of pancreatic fistula after pancreaticoduodenectomy. Methods: The clinical data of 581 patients undergoing pancreaticoduodenectomy from Dec. 2012 to Sep. 2018 in Cangzhou Central Hospital were retrospectively analyzed, including 327 cases of open pancreaticoduodenectomy (OPD) , 175 cases of laparoscopic assisted pancreaticoduodenectomy (LAPD) , and 79 cases of total laparoscopic pancreaticoduodenectomy. End-to-side pancreaticojejunostomy with pocket-insertion was used in all cases. The incidence of pancreatic fistula after operation was analyzed. Results: The overall incidence of grade B or C pancreatic fistula was 3.10% (18/581) after end-to-side pancreaticojejunostomy with purse-pocket insertion. The incidence of grade B or C pancreatic fistula in OPD group was 2.75% (9/327) . The incidence of grade B or C pancreatic fistula in LAPD group was 2.29% (4/175) . The incidence of grade B or C pancreatic fistula in TLPD group was 6.33% (5/79) . The three groups were divided into two subgroups according to the pancreatic texture. There was significant difference in pancreatic duct diameter between subgroups (P<0.05) , but there was no significant difference in the time of pancreaticojejunostomy and the incidence of pancreatic fistula after operation (P>0.05) . Conclusion End-to-side pancreaticojejunostomy with pocket insertion has the advantages of simple operation, strong adaptability, safety and high efficiency, and can control the incidence of pancreatic fistula after pancreaticoduodenectomy at an ideal level.
