摘要： Single incision laparoscopic surgery (SILS) is a novel minimally invasive surgical technique that is gaining popularity around the world. One of the most commonly performed procedures is single incision laparoscopic cholecystectomy (SILC). Most reported techniques utilize special purpose-made access port and articulating instruments, rendering the procedure costly and difficult to learn. This article provides a stepwise description of SILC technique using all straight instruments without the need for a special port. It aims to shorten the learning curve for surgeons wishing to adopt a safe and cost-effective SILC technique to their practice.

摘要：

Bile duct injury is a common complication of cholecystectomy. The timing of bile duct injury repair remains controversial. A recent review conducted in France reported 39% complications and 64% failure after immediate repair in 194 patients compared with 14% complications and 8% failure after late repair in 133 patients. A national review of 139 consecutive early repairs conducted at five hepatopancreaticobiliary centers in Denmark reported 4% mortality, 36% morbidity, and 42 restrictures (30%) at a median follow-up of 102 months, and only 64 patients (46%) demonstrated uneventful short-term and long-term outcomes. Most patients with bile duct injury present with bile leak and sepsis; thus, early repair is not recommended. Percutaneous drainage of bile and endoscopic stenting are the mainstays of treatment of bile leak because they convert acute bile duct injury into a controlled external biliary fistula. The ensuing benign biliary stricture should be repaired by a biliary surgeon after a delay of 4–6 weeks once the external biliary fistula has closed.

Beneficial effects of preventive cholecystectomy in patients with hepatic cancer

LIU Anzhong, LI Jun, HUA Huwei

《医学前沿（英文）》 2008年 第2卷 第2期   页码 139-142 doi: 10.1007/s11684-008-0026-x

摘要： There is no conclusive answer to the question whether excising gall bladder is helpful to the patient with hepatic cancer. The survival rate of patients with hepatic cancer for more than two years has been increased, and the incidence of complications of cholecystitis and gall stone are relatively higher among these patients, which may seriously complicate treatment of advanced hepatic cancer and decrease quality of life. The researchers conducted a prospective clinical investigation from 2002 to 2006 to assess the clinical significance of preventive cholecystectomy in patients with hepatic cancer. One hundred and eighteen cases of postoperative patients with hepatic cancer, who survived for more than two years, were followed up. Based on whether cholecystectomy was performed, the patients were divided into two groups including 48 cases with cholecystectomy and 70 cases with cholecyst reserved. The two-year morbidity of gall stone and morbidity of pain in the right upper abdomen of cholecyst reservation group were 54.29% and 68.57%, respectively, obviously higher than 0.00% and 20.83% of cholecystectomy group. Mainly for those treated with transcatheter arterial chemo-embolization, the morbidity of gall stone was 86.67% ( < 0.01). Therefore, preventive cholecystectomy is strongly recommended during hepatectomy to decrease the incidence of chronic cholecystitis and gall stone, especially for those whose chemotherapy and embolization will be carried out through hepatic artery and portal vein.

《医学前沿（英文）》 2017年 第11卷 第1期   页码 68-73 doi: 10.1007/s11684-016-0490-7

摘要：

This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery. Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5±1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61±0.77 pre-procedure to 1.27±0.88 post-procedure (P?<?0.001). The blood pressure of 48 of the 56 cases (86%) with preoperative intermittent high blood pressure returned to normal post procedure. A total of 50 patients (71%) recorded improvements on the hypertension control scale, with the overall mean score decreasing from 3.1±1.0 pre-procedure to 1.4±1.0 post-procedure (P?<?0.001). Therefore, successful laparoscopic fundoplication may result in better blood pressure control in some hypertensive GERD patients. This result suggests a possible connection between gastroesophageal reflux and hypertension.

Design and calibration of a new high-definition three-dimensional laparoscopic system

Jia TANG,Li-qiang WANG,Bo YUAN,Hong JIANG,Qi-ming ZHU

《信息与电子工程前沿（英文）》 2015年 第16卷 第1期   页码 79-84 doi: 10.1631/FITEE.1400149

摘要： We present a high-definition (HD) 3D laparoscopic system including a dual channel optical system, two cameras, a camera control unit (CCU), and an HD 3D monitor. This laparoscopic system is capable of outputting dual high-definition videos and providing vivid 3D images. A modified pinhole camera model is used for camera calibration and a new method of depth measurement to improve precision. The average error of depth measurement measured by experiment (about 1.13 mm) was small in proportion to the large range in distance of the system (10-150 mm). The new method is applicable to any calibrated binocular vision system.

摘要： Laparoscopic liver surgery has been increasingly used for the treatment of pediatric liver diseases over the past decade due to the development of special laparoscopic instruments and improvements in the technique. A number of factors are considered when electing to undergo the surgical process, including age, type of liver disease, and so on. Especially in children with liver masses, the number of trocars used and the position of their placement must be carefully designed to achieve successful outcomes. In the current review, the application of various laparoscopic instruments and the methods used for the laparoscopic treatment of liver diseases in children over the past decade are summarized.

Chun Tang, Baolin Wang, Bing Xie, Hongming Liu, Ping Chen

《医学前沿（英文）》 2011年 第5卷 第3期   页码 302-305 doi: 10.1007/s11684-011-0145-7

摘要： A treatment method based on drainage via retroperitoneal laparoscopy was adopted for 15 severe acute pancreatitis (SAP) patients to investigate the feasibility of the method. Ten patients received only drainage via retroperitoneal laparoscopy, four patients received drainage via both retroperitoneal and preperitoneal laparoscopy, and one patient received drainage via conversion to laparotomy. Thirteen patients exhibited a good drainage effect and were successfully cured without any other surgical treatment. Two patients had encapsulated effusions or pancreatic pseudocysts after surgery, but were successfully cured after lavage and B ultrasound-guided percutaneous catheter drainage. SAP treatment via retroperitoneal laparoscopic drainage is an effective surgical method, resulting in minor injury.

《医学前沿（英文）》 2012年 第6卷 第3期   页码 311-316 doi: 10.1007/s11684-012-0205-7

摘要：

In the current study, we assessed and evaluated the costs and benefits of three popular methods of general anesthesia practiced in our department for gynecological laparoscopic surgery in recent years. Sixty adult female patients who underwent elective gynecological laparoscopic surgery under general anesthesia were randomly divided into three groups: group V, group I and group C. In group V, anesthesia was induced intravenously with midazolam, remifentanil, propofol and vecuronium, and maintained with continuous infusion of propofol and remifentanil. In group I, anesthesia was intravenously induced with midazolam, fentanyl, propofol and vecuronium, and maintained with inhaled isoflurane and intravenous bonus of fentanyl. In group C, anesthesia was induced as in group I, but maintained with isoflurane inhalation combined with propofol-remifentanil infusion. All patients received vecuronium for muscle relaxation. Perioperative incidences of complications and total anesthesia costs for patients in all groups were recorded. In addition, postoperative satisfaction of the patients was also noted, and similar outcomes of the satisfaction were reported in all 60 patients. Although there was no statistical significance among groups, the incidence of postoperative nausea and vomiting were higher in group C, and the rates of shivering and the needs for analgesics were higher in group V. Anesthesia costs in group I were the lowest. Therefore, it is concluded that the costs of anesthesia induced with midazolam, fentanyl, propofol, vecuronium, and maintained with isoflurane, fentanyl and vecuronium are cheapest, and there is no significant difference in patients’ satisfaction and safety among the three above-mentioned methods of anesthesia in our department.

《医学前沿（英文）》 2011年 第5卷 第3期   页码 310-314 doi: 10.1007/s11684-011-0152-8

摘要：

Modified laparoscopic microsurgical tubal anastomosis is an alternative for microsurgical anastomosis via laparotomy to reverse sterilization in women with renewed child wish. The current study aims to evaluate the fertility outcome after modified laparoscopic microsurgical tubal anastomosis. A retrospective study was performed. Fifty-eight women who underwent modified laparoscopic microsurgical tubal anastomosis were monitored to investigate the fertility outcome and characteristics of this new technology. Of the 58 patients, the cumulative pregnancy rate (PR) in the 42 patients with follow-up data was 23.8% (10/42), 57.1% (24/42), 66.7% (28/42), and 73.8% (31/42) within 6, 12, 24, and 36 months after surgery, respectively. The intrauterine PR was 69.0% (29/42). Two patients (4.8%) had ectopic pregnancies that occurred within 24 months of surgery; three cases ended in spontaneous abortion. The delivery rate was 83.9% (26/31). The length of operating time was 1.2±0.3 h, with a range of 1.0–2.5 h (60–145 min), and the mean time was approximately 75 min. The blood loss was relatively small, between 10 and 50 ml with an average amount of 22 ml. Thus, the modified laparoscopic tubal anastomosis is a highly successful procedure and a viable alternative to open abdominal microsurgical approaches. Compared with the traditional laparoscopic tubal sterilization reversal, this modified approach has three advantages: (1) less invasive approach via a trocar reduction; (2) remodeling of tube is better performing tied together after 3–4 sutures; and (3) faster operating time.

摘要： Laparoscopic pancreaticoduodenectomy (LPD) is a challenging operation to general surgeon. Up to date, only about 135 cases have been reported, 16 cases in China, 119 cases outside China. The reconstruction of alimentary system is a key procedure to ensure success of the whole surgery. It is worth investigating the methods of reconstruction in LPD. A retrospective study is made to investigate the methods of reconstruction in LPD. We analyze 13 cases of LPD performed in our center. Child s or modified Child s method was used to make the reconstruction in our practice. We tried three methods to make the anastomosis of pancreaticojejunostomy, including end-to-end dunking binding pancreaticojejunostomy in two cases, end-to-end dunking pancreaticojejunostomy using interrupted suture in two cases, and duct-to-jejunal end-to-side embedding pancreaticojejunostomy in nine cases. The clinical data was collected and analyzed. Three of four patients, who underwent end-to-end pancreaticojejunostomy, had a little pancreatic leakage, especially in the first case. None of other nine patients, who underwent duct-to-jejunal end-to-side embedding pancreaticojejunostomy, was detected to have pancreatic leakage, and the operating time of these nine cases was less than other four cases. Duct-to-jejunal end-to-side embedding pancreaticojejunostomy is a safe and efficient method of reconstruction in LPD.

摘要：

Robotic system has been increasingly used in pancreatectomy. However, the effectiveness of this method remains uncertain. This study compared the surgical outcomes between robot-assisted laparoscopic distal pancreatectomy and conventional laparoscopic distal pancreatectomy. During a 15-year period, 35 patients underwent minimally invasive approach of distal pancreatectomy in our center. Seventeen of these patients had robot-assisted laparoscopic approach, and the remaining 18 had conventional laparoscopic approach. Their operative parameters and perioperative outcomes were analyzed retrospectively in a prospective database. The mean operating time in the robotic group (221.4 min) was significantly longer than that in the laparoscopic group (173.6 min) (P = 0.026). Both robotic and conventional laparoscopic groups presented no significant difference in spleen-preservation rate (52.9% vs. 38.9%) (P = 0.505), operative blood loss (100.3 ml vs. 268.3 ml) (P = 0.29), overall morbidity rate (47.1% vs. 38.9%) (P = 0.73), and post-operative hospital stay (11.4 days vs. 14.2 days) (P = 0.46). Both groups also showed no perioperative mortality. Similar outcomes were observed in robotic distal pancreatectomy and conventional laparoscopic approach. However, robotic approach tended to have the advantages of less blood loss and shorter hospital stay. Further studies are necessary to determine the clinical position of robotic distal pancreatectomy.

摘要： Gastroesophageal reflux disease (GERD) was diagnosed and fundoplication was performed, which relieved the symptoms. This paper explores the effect of fundoplication on GERD-related respiratory symptoms. From January 2007 to October 2008, 64 patients with respiratory symptoms related to GERD were consecutively enrolled for laparoscopic fundoplication. Of these, 60 patients had respiratory symptoms mainly combined with gastroesophageal reflux, while four had respiratory symptoms only. All patients had GERD confirmed, and medical treatment provided before surgery resulted in an insufficiently favorable effect or even producing further complications. All the patients were requested to fill a questionnaire form regarding the severity of symptoms and their medication so as to make an evaluation score for the follow-up. The outcome of respiratory symptoms after surgery was as follows: excellent in 23 cases (35.9%); good in 28 (43.8%); fair in 5 (7.8%); poor in 8 (12.5%). The mean respiratory symptom score decreased from 6.3±2.65 to 2.33±2.37. Laparoscopic fundoplication can be an effective treatment for the majority of patients with GERD-related respiratory symptoms.

摘要： Laparoscopic pancreatic surgery has been gaining increasing recognition in recent years, and its practice has increased despite its highly complex procedure and longer learning curve compared with surgeries for other abdominal organs. Laparoscopic distal pancreatectomy and tumor enucleation are two of the fastest-growing techniques and are currently in wide use because of their comparable technical simplicity. Literature review showed that laparoscopic distal pancreatectomy and enucleation are safe and efficient approaches for benign and low-degree malignant tumors; however, the indication for malignant tumors remains controversial. Laparoscopic pancreaticoduodenectomy is practiced in a limited number of surgical centers and presented as case reports or in small series. Although its feasibility was demonstrated by many surgeons, whether the laparoscopic procedure can achieve benefits comparable to or even more prominent than those of an open procedure has not been clinically proven. Prospective, randomized, controlled trials of laparoscopic operation versus open pancreatic surgery are necessary to justify the wide application and routine practice of the laparoscopic procedure for pancreatic lesions.
