BACKGROUND As one of the major abdominal operations, pancreaticoduodenectomy (PD) involves many organs. The operation is complex, and the scope of the operation is large, which can cause significant trauma in patients. The operation has a high rate of complications. Pancreatic leakage is the main complication after PD. When pancreatic leakage occurs after PD, it can often lead to abdominal bleeding and infection, threatening the lives of patients. One study found that pancreatic leakage was affected by many factors including the choice of pancreaticojejunostomy method which can be well controlled. AIM To investigate the choice of operative methods for pancreaticojejunostomy and to conduct a multivariate study of pancreatic leakage in PD. METHODS A total of 420 patients undergoing PD in our hospital from January 2014 to March 2019 were enrolled and divided into group A ( n = 198) and group B ( n = 222) according to the pancreatointestinal anastomosis method adopted during the operation. Duct-to-mucosa pancreatojejunostomy was performed in group A and bundled pancreaticojejunostomy was performed in group B. The operation time, intraoperative blood loss, and pancreatic leakage of the two groups were assessed. The occurrence of pancreatic leakage after the operation in different patients was analyzed. RESULTS The differences in operative time and intraoperative bleeding between groups A and B were not significant ( P > 0.05). In group A, the time of pancreatojejunostomy was 26.03 ± 4.40 min and pancreatic duct diameter was 3.90 ± 1.10 mm. These measurements were significantly higher than those in group B ( P < 0.05). The differences in the occurrence of pancreatic leakage, abdominal infection, abdominal hemorrhage and gastric retention between group A and group B were not significant ( P > 0.05). The rates of pancreatic leakage in patients with preoperative albumin < 30 g/L, preoperative jaundice time ≥ 8 wk, and pancreatic duct diameter < 3 mm, were 23.33%, 33.96%, and 19.01%, respectively. These were significantly higher than those in patients with preoperative albumin ≥ 30 g/L, preoperative jaundice time < 8 wk, and pancreatic duct diameter ≥ 3 cm ( P < 0.05). Logistic regression analysis showed that preoperative albumin < 30 g/L, preoperative jaundice time ≥ 8 wk, and pancreatic duct diameter < 3 mm were risk factors for pancreatic leakage after PD (odds ratio = 2.038, 2.416 and 2.670, P < 0.05). CONCLUSION The pancreatointestinal anastomosis method during PD has no significant effect on the occurrence of pancreatic leakage. The main risk factors for pancreatic leakage include preoperative albumin, preoperative jaundice time, and pancreatic duct diameter.
BackgroundThe incidence and mortality of pancreatic adenosquamous carcinoma (PASC) have received little attention. The goal of our study was to explore the overall epidemiological trend of PASC at the population level. MethodsThe Surveillance, Epidemiology, and End Results database was used to collect the incidence, incidencebased (IB) mortality, and patient details for PASC from 2000 to 2017. The Joinpoint regression tool was used to examine the trends in incidence and IB mortality. The Kaplan-Meier approach was used for survival analysis. Univariate and multivariate Cox regression analyses were used to determine the independent prognostic factors. ResultsWe included 815 patients with PASC in the study. The incidence of PASC continuously increased from 2000 to 2017, with an annual percentage change (APC) of 3.9% (95% CI: 2.2-5.7%, P < 0.05). IB mortality also increased continuously, with an APC of 5.0% (95% CI: 2.5-7.6%, P < 0.05). Multivariate Cox regression analysis revealed that age, treatment, regional lymph node involvement, and tumor size were independent prognostic factors. Nomograms were created for PASC to predict 1-and 2-year survival probabilities, respectively. ConclusionsThe incidence and IB mortality of PASC had a sustained and rapid increase, indicating that the preventive and treatment measures for PASC were not ideal. We must identify the signi cance of this condition as soon as possible, and commit greater attention and resources to PASC research.
Background: This study aimed to determine the role of surgical treatment in patients with stage II intrahepatic cholangiocarcinoma (iCCA). Methods: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We divided stage II iCCAs into solitary tumors with vascular invasion (T2sN0M0) and multiple tumors with/without vascular invasion (T2mN0M0) according to the criteria of AJCC v.8. The Kaplan–Meier method and log-rank test were used to evaluate differences in overall survival (OS). We performed two propensity score-matching analyses with (PSM2) or without (PSM1) surgical treatment. Results: 667 and 778 iCCA patients with stage II and IIIB were recruited. After PSM2, there was no survival difference in stage II iCCA patients in hypothetical conditions with similar surgical proportions (p = 0.079). However, OS was significantly worse in patients with T2mN0M0 than T2sN0M0 when the actual surgical proportion existed after PSM1 (p < 0.001). OS was similar between T2mN0M0 and IIIB regardless of whether PSM1 (p = 0.907) or PSM2 (p = 0.699) was performed. The surgical treatment was verified to associate with prognosis. Conclusions: The survival benefit by surgical treatment was existed in Stage II but not in Stage IIIB iCCA patients. The OS for T2mN0M0 will approach that of T2sN0M0 if the surgical proportion is gradually increased.
BackgroundThe feasibility and safety of robotic extended cholecystectomy (REC) are still uncertain. This study was performed to compare the short- and long-term outcomes of REC with those of open extended cholecystectomy (OEC) for T1a–T3 gallbladder cancer.MethodsFrom January 2015 to April 2022, 28 patients underwent REC in our center. To minimize any confounding factors, a 1:2 propensity score-matching analysis was conducted based on the patients’ demographics, liver function indicators, T stage, and symptoms. The data regarding demographics, perioperative outcomes, and long-term oncologic outcomes were reviewed.ResultsThe visual analogue scale score was significantly lower in the REC than OEC group immediately postoperatively (3.68 ± 2.09 vs. 4.73 ± 1.85, P = 0.008), on postoperative day 1 (2.96 ± 1.75 vs. 3.69 ± 1.41, P = 0.023), and on postoperative day 2 (2.36 ± 1.55 vs. 2.92 ± 1.21, P = 0.031). In addition, the REC group exhibited a shorter time to first ambulation (P = 0.043), a shorter time to drainage tube removal (P = 0.038), and a shorter postoperative stay (P = 0.037), but hospital costs were significantly higher in the REC group (P < 0.001). However, no statistically significant difference was found in the operation time (P = 0.134), intraoperative blood loss (P = 0.467), or incidence of postoperative morbidity (P = 0.227) or mortality (P = 0.289) between the REC and OEC groups. In regard to long-term outcomes, the 3-year disease-free survival rate was comparable between the OEC and REC groups (43.1% vs. 57.2%, P = 0.684), as was the 3-year overall survival rate (62.8% vs. 75.0%, P = 0.619).ConclusionREC can be an effective and safe alternative to OEC for selected patients with T1a–T3 gallbladder cancer with respect to short- and long-term outcomes.
