Analysis of influencing factors on surgical outcome and exploration of technical principles during pancreaticojejunostomy / 中华外科杂志

Pancreaticojejunostomy is the most common anastomosis following pancreaticoduodenectomy and middle pancreatectomy. The detailed surgical technics of pancreaticojejunostomy vary dramatically, but none of them can achieve zero fistula rate. In recent years,with the development of new surgical concept,application of new surgical technology, high-tech materials and instruments,the incidence of pancreatic fistula has decreased. At the same time,researches on investigating the risk factors of pancreaticojejunostomy are gradually deepening. Based on years of surgical experience on pancreaticojejunostomy and current literatures, this paper analyzes the factors affecting the effect of pancreaticojejunostomy, such as the patient's basic physical state,pancreatic texture and diameter of the pancreatic duct,pathology and course of the disease,surgical technology and perioperative management,and summarizes six technical principles for pancreaticojejunostomy to be shared with surgical comrades:appropriate tension,protection of blood supply,hermetic closure of pancreatic section,accurate connection of pancreatic duct and intestinal mucosa,individualization,learning and accumulation of experience.

Syndrome of uremic encephalopathy and bilateral basal ganglia lesions in non-diabetic hemodialysis patient: a case report.

BACKGROUND: Uremic encephalopathy (UE), a toxic metabolic encephalopathy, is an uncommon complication resulting from endogenous uremic toxins in patients with severe renal failure. UE syndrome can range from mild inattention to coma. The imaging findings of UE include cortical or subcortical involvement, basal ganglia involvement and white matter involvement. The basal ganglia type is uncommon, although previous cases have reported that Asian patients with diabetes mellitus (DM) are usually affected. CASE PRESENTATION: A 32 year-old woman with a history of non-diabetic hemodialysis for 3 years suffered from severe involuntary movement, and brain magnetic resonance imaging showed symmetrical T2-weighted imaging (T2WI) and T2/fluid-attenuated inversion recovery (T2FLAIR) hyperintense nonhemorrhagic lesions in the bilateral basal ganglia. She was diagnosed with UE as syndrome of bilateral basal ganglia lesions, due to a combined effect of uremic toxins and hyperthyroidism. After treatment with high frequency and high flux dialysis, hyperbaric oxygen therapy and declining parathyroid hormone, the patient achieved complete remission with normal body movement and was discharged. CONCLUSION: UE with basal ganglia involvement is uncommon, although generally seen in Asian patients with DM. Our case reported a hemodialysis patient that had non-diabetic UE with typical bilateral basal ganglia lesions, presenting with involuntary movement.
