Recently, we introduced a method of suspender pancreaticojejunostomy(PJ) to the PD. In this study, we retrospectively analyzed various risk factors for complications after PD. We also introduced and assessed the suspender PJ to demonstrate its advantages.Methods: Data from 335 patients with various periampullary lesions, who underwent the Whipple procedure(classic Whipple procedure or pylorus-preserving) PD by either traditional end-to-side invagination PJ or suspender PJ, were analyzed. The correlation between either perioperative or postoperative complications and corresponding PD approaches was evaluated by univariate analysis.Results: A total of 147 patients received the traditional end-to-side invagination PJ, and 188 patients were given the suspender PJ. Overall, 51.9% patients had various complications after PD. The mortality rate was 2.4%. The POPF incidence in patients who received the suspender PJ was 5.3%, which was significantly lower than those who received the traditional end-to-side invagination PJ(18.4%)(P < 0.001).Univariate analysis showed that PJ approach and the pancreas texture were significantly associated with the POPF incidence rate(P < 0.01). POPF was a risk factor for both postoperative abdominal cavity infection(OR = 8.34, 95% CI: 3.99–17.42, P < 0.001) and abdominal cavity hemorrhage(OR = 4.86, 95% CI:1.92–12.33, P = 0.001).Conclusions: Our study showed that the impact of the pancreas texture was a major risk factor for pancreatic leakage after a PD. The suspender PJ can be easily accomplished and widely applied and can effectively decrease the impact of the pancreas texture on pancreatic fistula after a PD and leads to a lower POPF incidence rate.展开更多

Theirage ranged from 41 to 79 years with a mean of 59.6 years, Thirty-four patients suffered from gallstones.Abdominal pain (83.9%) and jaundice (41.1%) were the main symptoms. Thirty patients (Nevin stageⅡ in 5 patients, Ⅲ in 3, Ⅳ in 4, and Ⅴ in 18) received radical or extended radical resection; non-radicalresection was performed in 11 patients of Nevin stage Ⅴ; and 15 patients of Nevin stage Ⅴ were subjectedto biopsy with or without palliative bypass procedure. Statistical analysis showed that operative procedure,staging of Nevin, and gallstone affected significantly postoperative survival, but age, sex, preoperativeserum bilirubin level, numbers of tumor location, histopathological type and grade were not significantprognostic factors. After radical resection was classified with Nevin staging, we found that all the patientsof stage Ⅱ were alive. Meanwhile the postoperative survival periods of radical resection groups of stage Ⅲto Ⅴ, palliative resection group, and biopsy with/without palliative drainage group were statisticallydifferent.CONCLUSIONS: From Nevin stage Ⅱ to Ⅴ, the survival period of respective stage group, which treatedwith curative operation, became shorter gradually. In those patients of stage Ⅴ, the survival period ofcurative operation group was longer than that of palliative resection group, and that of the latter was betterthan that of biopsy with/without palliative drainage group. So radical resection was still the unique way tobetter prognosis.展开更多
