ABSTRACT
Objective:To evaluate the excitation and identification of parathyroid autofluorescence in thyroid surgery by a fluorescence laparoscopic system.Methods:The clinical data of 6 patients with papillary thyroid carcinoma who underwent Laparoscopic thyroid surgery at the Second Affiliated Hospital of Guangxi Medical University from Mar. 2022 to Apr. 2022 were collected. The autofluorescence of the parathyroid glands was detected and identified by the OptoMedic fluorescence laparoscopic system during the operation. A rapid frozen sections pathological examination of possible parathyroid tissue with autofluorescence was performed to determine whether it was parathyroid tissue.Results:Parathyroid autofluorescence with different intensities was visualized intraoperatively in all 6 patients, and it was confirmed as parathyroid tissue by rapid frozen pathological section.Conclusions:The parathyroid gland has a unique autofluorescence feature. Using this feature to identify, locate and protect the parathyroid gland during surgery can help reduce the complications of parathyroid injury.
ABSTRACT
With the advancement and development of life science and technology,many problems in liver surgery have been solved,and the surgical procedures of liver surgery have been continuously developed and the indications for surgery have been continuously expanded.Benign and malignant lesions and even donor liver can be performed under laparoscopy.The indications for laparoscopic liver resection are expanding,from superficial liver resection to a wider range of anatomical resection.At the same time of technological advancement,along with the development of the humanistic spirit,liver resection is not only the removal of lesions,but the pursuit of rehabilitation,which is "the best rehabilitation with minimal trauma".Laparoscopic liver resection has been greatly developed due to the spread of the concept of "precise medicine".
ABSTRACT

ABSTRACT
Objective To compare the feasibility and safety of laparoscopic versus open hepatectomy.Methods The data of 165 patients who underwent laparoscopic hepatectomy were compared with 170 patients who underwent open hepatectomy in our hospital from November 2002 to December 2010.Results Laparoscopic hepatectomy was successfully carried out in 159 patients and 6 patients were converted to open operation because of intra-operative hemorrhage.The 170 patients in the open operative group had open hepatectomy successfully carried out.The hospital stay and cost in the laparoscopic group(7.6±1.3 d,31767.4±220.1(￥))were less than the open operation group(14.6±3.3 d,35127.3±392.2(￥))(t=-12.657,P＜0.001; t=-78.859,P＜0.001).There was no significant difference in Pringle's manoeuvre time,blood loss and postoperative complications(20.6 ±8.5vs.18.6±6.5 min,t=2.108,P=0.068),(420.8±76.5 vs.395.9±96.1 ml,t=2.157,P=0.063),(0 vs.4 cases,t=2.011,P=0.156))between the 2 groups.The operative time in the laparoscopic group was significantly longer than the open group(59.6 ± 12.2 vs.42.7 ± 22.6 min)(t=6.941,P＜0.001).Conclusions Laparoscopic hepatectomy is feasible and safe.It has the advantages of having less trauma and quicker recovery for tumors which were located superficially in the left liver and in the inferior part of the right liver.The operative time was longer than open hepatectomy,but there was no significant difference between the 2 groups in Pringle's manoeuvre time,blood loss and postoperative complications.The hospital stay and total hospital cost in the open operation group were higher than the laparoscopic hepatectomy group.
ABSTRACT
Objective To evaluate the feasibility and efficacy of laparoscopic treatment of hepatic hemangioma. Methods The clinical data of 27 patients who received laparoscopic treatment of hepatic hemangioma from November 2003 to October 2009 were retrospectively analyzed. The hepatic inflow to the liver or to a hemiliver was temporarily blocked using a Pringle manoeuvre with a self-invented laparoscopic blocker at the porta hepatis or at the pedicle to the relevant hemiliver. The Electriccautery and ultracision were used for liver transaction. Results Laparoscopic treatment of hepatic hemangioma was successfully performed in 25 patients. Conversion to laparotomy was required in two (8%) patients for uncontrollable bleeding. There were no major postoperative complications and no mortality. The mean tumor diameter was (6.34±2. 17) cm. The operating time was ( 105.21 ±72.76)min. The time of hepatic inflow block was (10. 17±12. 21)min. The blood loss was (115. 5±212.14)ml. The volume of blood transfusion was (0. 87 ± 1.45)U. The volume of postoperative drainage was (112.60±201.03)ml. The time taken to return to normal activity was (2. 0±0. 8) days.The length of postoperative hospital stay was (5.5±2.4) days. The length of total hospital stay was (12. 5 ±5.3) days. The total cost was RMB10041.6±8678. 7. Conclusion In selected patients, laparoscopic treatment of hepatic hemangioma was safe and feasible.

ABSTRACT
Objective To assess the safety and effectiveness of laparoscopically total extraperitoneal (TEP) repair using two mesh cross and overlap without stapler technique and to discuss the cause of main complications. Methods In this study 243 cases of inguinal hernia were randomly divided into two groups. One group underwent two meshes cross and overlap no fixation TEP, the other underwent a single mesh stapling fixation TEP. The average postoperative follow-up was ( 28 ± 6 ) months. For comparing the effect of the two approaches, statistical analysis including the χ2 test and Student's t test was carried out where appropriate. A p value of less than 0. 05 was considered statistically significant. Results The recurrence rate for the mesh no fixation group ( 1.9% ) did not increase when compared to mesh fixation group( 2. 9% ) ( P ＞ 0. 05 ). The overall postoperative complication rate or individual complication rate was not significantly different between the two groups. Conclusions Laparoscopically total extraperitonealrepair(TEP) using two mesh cross and overlap no fixation technique is safe and reliable.

ABSTRACT
Objective To evaluate the feasibility of laparoscopic left lateral hepatic lobectomy(Ⅱand Ⅲ segments)for the treatment of primary hepatic carcinoma(PHC).Methods From January 2002 to June 2007,23 patients with PHC were treated by laparoscopic left lateral hepatic lobectomy.During the operation,after the portal blood stream was blocked by portal clamps,left lateral lobectomy was performed by using electric or ultrasonic scalpel.Then,laparoscopic hepatic suture was carried out,and fibrin sealant was used to cover the surgical surface.Results Laparoscopic left lateral hepatic lobectomy was completed in all the 23 cases with a mean operation time of(131.7?33.9)min and mean blood loss of(297.9?124.0)ml.All the patients recovered well without postoperative complications and were discharged(5.5?1.3)days after the operation.Among the cases,20(20/23,87%)were followed up for 2-24 months(2-12 months for 9 cases,and 13-24 months for 11 cases),during which no patients died,3 patients had recurrent hepatic carcinoma.Conclusions Laparoscopic left lateral hepatic lobectomy is feasible for PHC.The method should be the first choice for left lateral PHC because it is safe and minimally invasive.
ABSTRACT
Objective To investigate the laparoscopic anatomy of the spleen vessels and its clinical application. Methods The data of 47 cases of total laparoscopic splenectomy (TLS) were analyzed. Among the patients, 21 had cirrhotic portal hypertension, 19 had thalassemia, 2 idiopathic thrombocytopenic purpura, 2 hereditary spherocytosis, 1 angioma of the spleen, 1 splenic cyst, and 1 primary hypersplenism. The color of the spleen was observed after the splenic artery near the pancreatic tail was ligated. And then the splenic artery was categorized according to the color. Results Among the 47 cases, 34 (72.3%) were categorized as typeⅠ, 9 were type Ⅱ (19.1%), and 2 were type Ⅲ (4.3%). The arterial anatomy was unclear under a laparoscope in 2 cases (4.3%). The TLS was completed in 46 cases with a success rate of 97.9% (46/47). Among the cases, 14 received extensive esophagogastric devascularization simultaneously,and 3 patients who had thalassemia underwent cholecystecotomy after the TLS because of gallbladder stones. One case was converted to an open surgery because of extensive bleeding owning to coagulation disorder. The spleen artery was ligated in 43 cases, and the hilar vessels were resected by dissecting and ligating in 45 cases. The Operation time averaged at (110?35) min (range 50-240 min), and the mean intraoperative blood loss was (160?87) ml (range, 20-1500 ml). Conclusions In spite of the prominent type Ⅱ of the spleen vessels, the spleen artery can be dissected and ligated at the level of the superior edge of the pancreatic tail to stop the blood supply to the spleen. The hilar vessels can be resected by dissecting and ligating. The spleen artery ligation and hilar vessels resection by dissecting and ligating are effective in controlling intraoperative bleeding and avoiding pancreas injury.
