Objective:
To evaluate the feasibility and strategy of the lesser omentum approach for laparoscopic pancreatic enucleation.
Methods:
Between June 2011 and October 2013, 6 laparoscopic pancreatic enucleations were performed by lesser omentum approach.The average age was 42 years, including 1 male and 5 female.The preoperation diagnosis of 6 cases were pancreatic islet cell tumors determined by abdominal CT/MRI, ultrasound and digital subtraction angiography.The tumors of 3 cases located in pancreatic neck, 2 tumors located in neck and body of pancreas, and 1 tumor located in pancreatic body.Their biggest tumor diameter were 0.8-2.5 cm.
Results:
Among the 6 cases, all laparoscopic pancreatic enucleations were successfully performed.None of the patients were converted to open operation.Eestimated blood loss was (26.7±18.6)ml, operating time was (82.5±19.4)minutes, and postoperative length of stay was (5.17±1.17)days.Additionally, postoperative complication included grade A pancreatic fistula in 1 case.After 36-64 months followed-up, there was no tumor recurrence and clinical symptom disappeared.
Conclusion
For the islet cell tumors located in pancreatic neck and body, the lesser omentumapproach may contribute to good surgical view and operative space, which can make pancreatectomy safer and easier for clinical application.

Objective To analyze the clinical characteristics,imaging manifestations and prognoses of anti-GABAB receptor antibodies encephalitis.Methods The clinical manifestations,laboratory findings and radiological data of 13 patients with anti-GABAB receptor encephalitis,admitted to our hospital from September 2015 to March 2017,were retrospectively analyzed.Modified Rankin scale (mRs) was performed to evaluate the prognoses (good prognosis:mRs scores < 2;poor prognosis mRs scores≥3).Results These 13 patients had an average age of 58 years (ranged 49-76 years) with a male to female ratio of 12:1.The major clinical features,including epileptic seizure,were found in 12 patients,psychiatric symptoms in 11 patients,cognitive disorder in 7 patients,and disturbance of consciousness in 4 patients.Brain MR imaging showed abnormal signal in 5 patients:4 were located in the hippocampus and amygdaloid,and one in the pons and left temporal lobe.Five patients showed abnormalities in PET-CT,including 4 with temporal hypermetabolism and 1 with cortical hypometabolism.Chest CT showed lung occupying lesions in 4 patients,of which 2 patients were diagnosed as having small cell lung cancer (SCLC) by pathological examination.Ten patients received immunomodulatory therapy,and three were with supportive care.After the average of 8 months of follow-up,7 patients had good prognosis,5 patients had poor prognosis and one patient lost of follow up.Conclusions Anti-GABAB receptor encephalitis frequently occurs in elderly male subjects and the main characteristic includes prominent refractory epilepsy and shows neurological improvement on immunotherapy.It can accompany by SCLC and have a relatively poor prognosis.
