OBJECTIVETo evaluate the effect and safety of enucleation of insulinoma under the Da Vinci robotic surgical system combination with intraoperative ultrasonography(IOUS) for the localization.

METHODSThe clinical materials of 50 insulinoma cases which underwent IOUS and assisted by the robotic surgical system from September 2012 to September 2014 in Peking Union Medical College Hospital were reviewed retrospectively. The patients were followed up by outpatient review and telephone until October 2014. The diagnostic accuracy rate, operation time, blood loss, complications and cure rate were analyzed by t-test.

RESULTSThe locations of tumors were 13 in the head, 21 in the body and 13 in the tail of pancreas, 2 were multiple insulinoma, 1 was ectopic to mesenterium.The average operation time was 142 minutes; the average blood loss was 165 ml.Three(6.0%) patients were transformed to open.One patient experienced postoperative bleeding about 300 ml on the 7(th) day after operation and no infection and perioperative death.Thirty-five cases were of class A and 14 of class B according to the clinical grading of postoperative pancreatic fistula.The blood glucose 60 minutes after tumor dissection was significantly elevated than that before operation ((6.2±1.8)mmol/L vs.(3.7±1.2)mmol/L)(t=-6.89, P<0.01). The cure rate was 100% as all the patients' symptoms were disappeared during follow-up time.

CONCLUSIONSCombination IOUS is a highly sensitive method for the localization of insulinoma, which is helpful in localizing tumors precisely in insulinoma cases assisted by robotic surgical system and shortening operation time.It is safe and effective for insulinoma enucleation.

OBJECTIVETo assess the effect of preoperative long course radiotherapy (RT) on anastomotic leakage (AL) after low anterior resection(LAR) for rectal cancer.

METHODSMedline, EMBASE, China National Knowledge Infrastructure,the Cochrane Library databases and other databases were searched for relevant studies. Correlation between preoperative long course RT and AL after LAR for rectal cancer was examined. Review Manager 5.2 software was used to pool raw data and test the heterogeneity of existing studies and to calculate the incorporated odds ratio (OR) and 95% confidence interval (95%CI). Finally, forest plots and funnel plots were created to allow for visual comparison of the results or the effect of publication bias.

RESULTSA total of 881 studies were identified and 10 studies (n=7829) were eligible for the meta-analysis, including 2581 cases of preoperative RT, and 5248 cases of surgery alone without RT. There was no significant difference in anastomotic leakage rate between the two groups (OR:1.17, 95%CI:0.98-1.39, P=0.09).

CONCLUSIONSPreoperative long course RT did not increase the risk of postoperative AL after LAR in patients with rectal cancer.

Liver is one of the organs with the highest injury rate, and in recent decades, the guidelines for the treatment of liver trauma have changed considerably. Now, there is a growing consensus that the most important step is diagnosis and depending upon the degree of severity, non-operative therapy is the main treatment method for hepatic trauma if conditions permit. For serious hepatic trauma patients such as those with hemodynamic instability, they should be operated upon as soon as possible. Regardless of the surgical options, doctors should control damage to patients and try to prevent complications. New therapies such as hepatic artery embolization and liver transplantation have been more and more used for the treatment of serious hepatic damage in clinics.

OBJECTIVETo investigate the significance of using high-frequency 2-dimonsional ultrasonography and color Doppler ultrasonography in the following-up of breast bulging operation.

METHODS7-11 MHz high-frequency 2-dimonsional ultrasonography and color Doppler ultrasonography were used on 18 patients, whose one or two breasts had abnormal symptom after breast bulging operation.

RESULTSImplants or blood swelling which took on a bag have no or low echo district, its margin is clear, regular and has a clear boundary line with the tissue around breast. The breaking and oozing, outing, moving, infection of implants, blood swelling, and sclerosis of wrapping membrane after breast bulging operation have special 2-dimonsional voice picture and the tissue around it has more or less color blood picture and Doppler frequency expression.

CONCLUSIONTechnique of shadow-picture Ultrasonography has great diagnose value and clinical significance in the detection of complications after breast bulging operation.

Diaphragm excursion,diaphragm thickness,and diaphragmatic thickening fraction are three indicators for evaluating the two hemidiaphragms by ultrasound.Diaphragm ultrasound has been widely applied in clinical practice including anesthesia management.It can help to diagnose postoperative residual curarisation and identify patients at a high risk of suffering from postoperative pulmonary complications.It can serve to recognize patients with diaphragm paralysis due to surgical or anesthetic factors as early as possible.Moreover,diaphragm ultrasound plays a role in preoperative pulmonary function assessment for special sufferers with chronic obstructive pulmonary disease,adolescent idiopathic scoliosis,or neuromuscular disease.Apart from these,diaphragm ultrasound can give anesthesiologists and colleagues in intensive care unit an important clue for extubation and weaning from mechanical ventilation of patients.

The anterior cruciate ligament (ACL) is an important stabiliser of the knee and is commonly torn in sports injuries. Common indications for imaging after ACL reconstruction include persistent symptoms, limitation of motion and re-injury. Important postoperative complications include graft failure, impingement, arthrofibrosis and graft degeneration. This article aimed to familiarise the radiologist with magnetic resonance (MR) imaging appearances of properly positioned intact ACL grafts and to provide a comprehensive review of MR imaging features of complications following ACL reconstruction.

The postoperative neurological complications is associated with intraoperative cerebral emboli, which results from extracorporeal circulation and operation. It can effectively reduce the incidence of neurological complications with ultrasonic radiation. In fluids, a particle will change it's motion trail when it is acted by the radiation force generated by the ultrasound. This article mainly discuss how to shielding emboli with ultrasound. The equipment can transmit phased ultrasonic signals, which is designed on a FPGA development board. The board can generate a square wave, which is converted into a sine wave through a power amplifier. In addition, the control software has been developed on Qt development environment. The result indicates it's feasible to shielding emboli with ultrasonic radiation force. This article builds a strong foundation for the future research.
