ObjectiveThis review aimed to summarize the current epidemiological status and risk factors of pancreatic cancer at home and abroad.MethodThe literatures on epidemiology and risk factors of pancreatic cancer in recent years were collected and summarized.ResultsCurrently the overall incidence of pancreatic cancer was lower in all malignant tumors, but the mortality rate was the opposite. Incidence varies from region to region, the incidence rate in economically developed areas was higher than that of underdeveloped areas. Although the disease had made some progress in the fields of surgery, chemotherapy, an so on, the long-term survival of patients with pancreatic cancer was still not ideal. The onset of pancreatic cancer was associated with smoking, alcohol, obesity, dietary imbalance, age, gender, blood type, ethnicity, family history and genetic history, chronic pancreatitis, infection, and intestinal flora imbalance.ConclusionsPancreatic cancer is a high malignancy with a poor prognosis. It is influenced by a variety of risk factors. Therefore, it is especially necessary to pay attention to the primary prevention of pancreatic cancer and screen high-risk individuals regularly, to diagnose pancreatic cancer at an early stage.
Radical surgical resection is still the only potentially curative treatment for pancreatic cancer. With the update of minimally invasive concepts, the laparoscopic and robotic platform has been introduced to pancreatic surgery practice. The recent studies have demonstrated that minimally invasive procedure achieved similar or improved perioperative outcomes compared to the standard open approach. Neo-adjuvant chemotherapy is increasingly being applied in pancreatic surgery, making surgical resection more challenging. Numbers of patients undergoing minimally invasive resection following neo-adjuvant chemotherapy remain low. The author consulted the latest literatures at home and abroad and described the current situation of minimally invasive treatment of pancreatic cancer after neo-adjuvant chemotherapy.
ObjectiveTo investigate the occurrence and treatment of postoperative complications after laparoscopic laparoscopic pylorus-preserving pancreaticoduodenectomy (LPPPD) or pancreaticoduodenectomy (LPD). MethodThe clinical data of 130 patients undergoing LPD from October 2010 to December 2015 in West China Hospital of Sichuan University were analyzed retrospectively. ResultsOf 130 patients, postoperative complications occurred in 55 cases, including 24 cases of pancreatic fistula, 14 cases of gastric emptying disorder, 3 cases of anastomotic bleeding, 6 cases of peritoneal infection, 1 case of bile leakage, 1 case of venous thrombosis, 1 case of chylous leakage, 5 cases of peritoneal effusion, without the occurrence of stress ulcer and incision complications. There were significant difference in the incidence of pancreatic fistula (P=0.025), gastric emptying disorder (P=0.034), anastomotic bleeding (P=0.020), and peritoneal infection (P=0.016) among prophase group, metaphase group, and the later stage group. ConclusionsThe most common complication after LPD is pancreatic fistula. With the improvement of surgical techniques and procedures, incidences of some postoperative complications decreases gradually.
Objective To explore the feasibility and safety of Frey operation under laparoscopy in the treatment of chronic pancreatitis. Methods The clinical data of chronic pancreatitis patients who underwent laparoscopic Frey procedure in Division of Pancreatic Surgery, Department of General Surgery, West China Hospital, Sichuan University from 2021-2023 were retrospectively analyzed. Results Eleven patients with chronic pancreatitis complicated with pancreatic duct stones were included in the study, 7 of whom had a history of diabetes and (or ) impaired glucose tolerance, suggesting that pancreatic endocrine function was impaired. The median diameter of the main pancreatic duct measured by imaging method was 8 mm (4–20mm). The median operative time was 188 min (120–368 minutes), and the total intraoperative bleeding volume was 50 mL (20–100 mL). Postoperative pancreatic fistula did not occur, one case of postoperative abdominal fluid accumulation and hypoproteinemia improved after symptomatic supportive treatment such as anti infection, acid and enzyme inhibition, and nutritional rehydration. Postoperative bleeding occurred in 3 cases, including 1 case of intestinal anastomotic bleeding, which was sutured again under emergency laparoscopic intestinal anastomosis to stop bleeding. The other two cases improved after conservative management such as blood transfusion, plasma, vitamin K, acid inhibition, enzyme inhibition and hemostatic drugs. The median postoperative hospitalization time was 7 days (4–18 days), and no patient mortality happened within 90 days after surgery. Conclusion Laparoscopic Frey operation is feasible and a relatively safe and effective method for the treatment of chronic pancreatitis.
Objective To formulate an evidence-based treatment plan for a patient with suspected pyogenic liver abscess. Methods Based on the clinical questions raised by a patient with suspected pyogenic liver abscess, we searched The Cochrane Library (Issue 4, 2007), MEDLINE (1996 to January 2008), ACP Journal Club (1991 to January 2008), and Chinese Journal Full-text Database (1994 to January 2008) for systematic reviews, randomized controlled trials (RCTs) and case-control studies. The quality of the included studies was assessed. Results We did not find any systematic reviews or large-scale RCTs involving a comparison between laparoscopic drainage and surgical drainage in the treatment of pyogenic liver abscess. Four clinical retrospective studies closely related to our questions were found and assessed. These studies concluded that laparoscopic drainage for liver abscesses was a safe alternative for patients requiring surgical drainage. Based on the current evidence, as well as our clinical expertise and the patient’s values, laparoscopic drainage was not used for this patient and surgical drainage was applied. The patient was recovered and discharged. Conclusion Current evidence showed that laparoscopic drainage might be effective and safe for liver abscesses but high-quality large-scale randomized controlled trials are still required.
ObjectiveTo evaluate the feasibility and safety of laparoscopic radical antegrade modular pancreatosplenectomy through the ligament of Treitz approach for pancreatic body and tail cancer. MethodsOn 13th November 2017, we selected a patient with a suspicious malignant tumor in the body of pancreas but no evidence of metastasis or local invasion of the retroperitoneum for laparoscopic antegrade modular pancreatosplenectomy through the ligament of Treitz approach. The time of operation, the estimated blood loss, and post-operative complications were observed. ResultsThe procedure was completed successfully in 255 min, and the estimated blood loss was 200 mL, there was no need of transfusion and no significant post-operational complications had been observed. No tumor recurrence or distal metastasis was found after a 12 month’s follow-up. ConclusionLaparoscopic radical antegrade modular pancreatosplenectomy through the ligament of Treitz approach is a feasible and safe procedure for pancreatic body and tail malignant tumor in strictly selected patients.
Objective To analyse the correlation between cervical sagittal parameters of cervical spondylotic myelopathy in different sagittal curvature so as to find out representative cervical sagittal alignment parameters by measuring on MRI. Methods A retrospective analysis was made on the clinical data of 88 patients with cervical spondylotic myelopathy between July 2015 and January 2016. The C2-C7 Cobb angle, T1 slope (T1S), and C2-C7 sagittal vertical axis (C2-C7 SVA) were measured on T2-weight MRI. According to C2-C7 Cobb angle, the patients were divided into lordosis group (≥10° Cobb angle, 48 cases) and straightened group (0-10° Cobb angle, 40 cases). Intraclass correlation coefficient (ICC) was used for the reliability of measured data, Pearson correlation analysis for correlation between cervical sagittal parameters. Results ICC was 0.858-0.946, indicating good consistency of measurement parameters. The C2-C7 Cobb angle, T1S, and C2-C7 SVA were (5.6±2.4)°, (22.2±6.7)°, and (10.2±5.4) mm in straightened group, and were (20.1±8.2)°, (23.4±8.9)°, and (8.2±4.6) mm in lordosis group respectively. There was no correlation between the 3 parameters in straighten group (r=0.100,P=0.510 for T1S and C2-C7 Cobb angle;r=–0.100,P=0.500 for T1S and C2-C7 SVA;r=0.080,P=0.610 for C2-C7 Cobb angle and C2-C7 SVA). There was positive correlation between T1S and C2-C7 Cobb angle (r=0.540,P=0.000), negative correlation between T1S and C2-C7 SVA (r=–0.450,P=0.001), and no correlation between C2-C7 Cobb angle and C2-C7 SVA (r=–0.003,P=0.980). Conclusion For cervical spondylotic myelopathy in patients with cervical lordosis, only T1S measurement on MRI can be used as the main parameter to judge the sagittal curvature, but in patients with straightened cervical Cobb angle, measurements of T1S, C2-C7 Cobb angle, and C2-C7 SVA should be taken for the comprehensive evaluation of cervical sagittal curvature.
