ABSTRACT
BACKGROUND: The aim of this study is to explore a new manoeuvre of vascular control technique in laparoscopic spleen-preserving distal pancreatectomy (LSPDP). MATERIALS AND METHODS: A total of 63 patients were diagnosed with pancreatic tumour in our hospital from January 2013 to December 2018. In these cases, Kimura technique was utilised in 33 patients and total blood flow blocked technique was used in 30 patients. The clinical data of these 63 patients of were retrospectively analysed. RESULTS: Four groups of patients were operated smoothly. In Kimura group, 33 patients were carried out using Kimura technique. Four patients' spleens were resected because the spleen artery was damaged. Three patients among them were converted to open surgery. In the other group, one patient was converted to open and resected the spleen. When comparing the Kimura group with the last series group, the mean surgical time decreased by 27 min, the estimated blood loss decreased by 108 ml, which had a significant statistical difference, whereas postoperative haemorrhage and postoperative pancreatic fistula had no statistical difference. CONCLUSION: After ten patient's practice, application of new manoeuvre of vascular control technique in LSPDP is feasible and safe, with advantages of less blood loss and shorter operation time.
ABSTRACT
Background: To explore the safety and feasibility of laparoscopic caudate lobe (CL) resection for the treatment of hepatolithiasis. Methods: A retrospective study of nine patients who received laparoscopic CL resection for treatment of hepatolithiasis in our hospital from January 2013 to April 2017. Of these cases, we studied the patients' demographic data, the operation time, blood loss, post-operative hospital stay, post-operative complications and prognosis. Results: All the nine cases are performed successfully; the post-operative recovery was symptom free except for one case of post-operative bile leakage. Among them, there were six cases of CL resection in combination with other lobe, three cases of separate CL resection, and three cases of whole CL resection. The average operative time was 310 min (Range: 180-450 min), the average intraoperative blood loss was 530 ml (Range: 100-1000 ml), average post-operative hospital stay was 9 days (Range: 6-13 days), average total hospital stay was 10 days (Range: 9-19 days). Intraoperative calculi exhaustion rate was 66.7% (6/9), which at the end of treatment was 88.9% (8/9). No cases had calculi recurrence. Conclusion: The application of laparoscopic CL resection is feasible and safe.
ABSTRACT
BACKGROUND: The aim of this study is to explore the application value of layered suture technique in two-port laparoscopic choledocholithotomy with primary suture. MATERIALS AND METHODS: A prospective study of 267 patients received laparoscopic common bile duct choledocholithotomy with primary suture in our hospital from January 2014 to July 2017. Of these cases, layered suture technique was utilised in 110 patients, and single-suture technique was used in 157 patients. The operation time, post-operative hospital stay and post-operative complications were compared between the two groups. RESULTS: Two groups of patients were operated smoothly, with no conversations to laparotomy. Post-operative recovery was symptom free. The operative time was not significantly different between the two groups of patients (t = -'0.587,P= 0.086). The post-operative hospital stay and incidence of post-operative bile leakage were significantly lower in layered suture group than those in single-layer suture group ([7.6 ± 1.8] days vs. [5.8 ± 1.7] days, t = 2.776,P= 0.000; 4.5% [5/110] vs. 20.4% [32/157], χ2 = 9.885,P= 0.002). In the single-layer suture group, the incidence of post-operative bile leakage was significantly higher in patients complicated with acute cholangitis (44.4% [12/27] vs. 15.4% [20/130], χ2 = 11.634,P= 0.001), whereas in the layered suture group, the incidence of post-operative bile leakage was insignificantly different among patients with and without acute cholangitis (11.8% [2/17] vs. 3.2% [3/93], χ2 = 0.848,P= 0.357). CONCLUSION: Application of layered suture technique in laparoscopic choledocholithotomy with primary suture is feasible and safe, with advantages of less bile leakage and shorter hospital stay.
ABSTRACT
Background: In pancreatic cancer surgery, tumor violation of blood vessels is often considered a contraindication to surgery, especially laparoscopic surgery. We have completed 17 cases of major venous repair or reconstruction during laparoscopic pancreatic surgery, and we believe that this surgical method may be safe and feasible based on the skilled laparoscopic techniques. Materials and Methods: Between January 2014 and March 2022, a prospective cohort of 17 patients underwent major venous repair or reconstruction in our department. Among them, 15 cases underwent laparoscopic pancreaticoduodenectomy, 1 case underwent laparoscopic distal pancreatectomy, and 1 case underwent laparoscopic central pancreatectomy. In all of these cases, the pancreatic tumor invaded either portal veins (PV) or superior mesenteric veins. Given these clinical situations, 13 cases accepted laparoscopic venous resection and reconstruction, and 4 cases underwent venous repair. Results: Ten of 17 patients (58.8%) were male. The mean age was 67.1 (range 57-81). All patients' operations were successfully completed without transit to open. The average blocking time of venous resection and reconstruction was 30.1 (range 15-41) minutes and the average time of venous wedge resection and stitching was 24.0 (range 18-30) minutes. After surgeries, there were no complications such as PV stenosis, bleeding, thrombosis, and liver failure. Thirteen patients died within 2 years because of the tumor recurrence, and 4 patients are currently followed by outpatient visits, with no obvious signs of tumor recurrence. Conclusion: Studies have shown that the reconstruction or repair of the major veins under laparoscopic surgery is safe and effective. We recommended that surgeons need to have the basics of open surgery in case laparoscopic surgery cannot be continued, and have proficient laparoscopic surgery techniques combined with extensive training to achieve a learning curve for vascular anastomosis.
