Hepatic alveolar echinococcosis (HAE) is a severe zoonotic disease caused by Echinococcus multilocularis, primarily affecting the liver. Due to its insidious nature, the patients are often diagnosed at advanced stage, posing significant treatment challenges. We comprehensively examines the progress in surgical techniques for HAE management, focusing on various strategies across different disease stages. For the patients with early-stage HAE, ablation therapy has emerged as an effective treatment option. In the moderate to advanced cases, numerous surgical techniques and innovative approaches have been introduced, including laparoscopic surgery and liver transplantation, with particular emphasis on ex vivo liver resection and autotransplantation. These advancements offer more effective treatment options for the patients with advanced HAE. However, significant challenges persist, notably the preservation of adequate liver function while achieving complete lesion removal. Future research should prioritize the exploration and optimization of existing surgical methods, especially for advanced HAE cases. This includes refining surgical techniques through precise preoperative evaluation and staging, as well as developing novel surgical approaches to enhance safety and efficacy. Furthermore, multicenter and long-term follow-up prospective studies are crucial for validating the effectiveness of new surgical techniques and strategies. Through these concerted efforts, it is anticipated that the survival rates and quality of life for HAE patients will significantly be improved, marking a new era in the management of this complex disease.
ObjectiveTo evaluate the influence of sidestream dark field (SDF) imaging technology in laparoscopic anterior resection (LAR) of rectal cancer on postoperative anastomotic leakage. MethodsAccording to the inclusion and exclusion criteria, the patients diagnosed with rectal cancer and underwent LAR of rectal cancer in the Sichuan Provincial People’s Hospital from October 2017 to October 2021 were retrospectively analyzed and then were divided into the study group and the control group according to whether SDF imaging technology was used during the operation. The intraoperative and postoperative data, especially the postoperative anastomotic leakage, were analyzed. ResultsA total of 90 patients were involved in this study, including 40 patients in the study group and 50 patients in the control group. There were no statistical differences in the baseline data such as gender, age, boby mass index and so on between the two groups (P>0.05). Except that the incidence of anastomotic leakage in the study group was lower than that in the control group (P<0.05), there were no statistical differences in other indexes during and after operation between the two groups (P>0.05). The operation plans were changed in 8 patients of the study group. Except for the total vessel density (P=0.962), the microvascular flow index, perfusion vessel proportion, and perfusion vessel density in the last measurement of these 8 patients were higher than those in the first measurement (P<0.05). ConclusionFrom preliminary results of this study, real-time evaluation of intestinal microcirculation by SDF imaging technology can help surgeons evaluate microcirculation perfusion at the intestinal anastomosis and provide an important reference for surgical decision-making.
Objective To compare efficacy of laparoscopic and open duodenal circular drainage operation for superior mesenteric artery compressing syndrome (SMACS). Methods From December 2012 to December 2015, the clinical data of 23 cases of laparoscopic duodenal circular drainage operation (laparoscope group) and 28 cases of open duodenal circular drainage operation (open group) were analyzed. The operation time, intraoperative bleeding, postoperative ambulation time, postoperative analgesics usage, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time and postoperative incidence of complications were compared. The patients were followed up to confirm the effect after the operation. Results There were no differences of the age, sex, and body weight index between the laparoscope group and the open group (P>0.05). The operation time had no significant difference between these two groups (P>0.05). Compared with the open group, the intraoperative bleeding was less (P<0.05), the postoperative ambulation time, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time were shorter (P<0.05), the rates of postoperative analgesics usage, incision infection, pulmonary infection, and intestinal obstruction were lower (P<0.05) in the laparoscope group. The rates of anastomotic leakage and anastomotic bleeding, and total postoperative complications rate had no significant differences between these two groups (P>0.05). All the patients were followed up for 8–36 months. The clinical symptoms disappeared and the body weight increased to normal level in the two groups. Conclusions Preliminary results of in this study show that laparoscopic duodenal circular drainage operation in treatment of SMACS has some advantages such as less trauma, faster recovery, fewer complications and shorter hospitalization time. Laparoscopy will be an ideal choice for treatment of SMACS.
ObjectiveTo explore the feasibility and application value of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients.MethodsThe clinical data of patients who underwent LPD from August 2016 to July 2019 were retrospectively analyzed. The patients were allocated into the elderly group (≥65 years old) and non-elderly group (<65 years old). The early surgical outcomes and postoperative complications of the two groups were compared.ResultsIn this study, 69 cases of LPD were collected, including 42 cases in the elderly group and 27 cases in the non-elderly group. Compared with the non-elderly group, the proportion of patients complicated comorbidities was higher (P<0.05), albumin level was lower (P<0.05), and American Society of Anesthesiologists classification was higher (P<0.05) in the elderly group. There were no significant differences in the intraoperative conditions, postoperative recovery, and postoperative complications between the two groups (P>0.05), and there were no significant differences in the pathological results of postoperative malignant tumor between the two groups (P>0.05).ConclusionsFor elderly patients with over 65 years old, LPD is a safe and feasible surgical procedure for clinical practice. Meanwhile, early surgical outcomes are satisfactory, postoperative complications are not increased, and tumor cure effect can be achieved.
ObjectiveTo investigate the clinical effect of “Double R” pancreatojejunostomy in laparoscopic pancreaticoduodenectomy (LPD).MethodsThe clinical data of 20 patients underwent “Double R” pancreaticojejunostomy in the LPD from November 2018 to December 2019 in this hospital were collected retrospectively. The duration of pancreaticojejunostomy, incidence of postoperative pancreatic fistula, incidence of other complications, mortality, length of stay, and other clinical outcomes were analyzed.ResultsThere were 5 males and 6 females. The age was (56±10) years old. The body mass index was (22.6±4.4) kg/m2. The LPDs were successfully performed in all 20 patients, no patient transferred to the laparotomy, and no patient died within 30 d. There were 6 patients with papillary adenocarcinoma of the duodenum, 5 patients with adenocarcinoma of the lower part of the common bile duct, 2 patients with adenocarcinoma of the pancreatic duct, 3 patients with serous cystadenoma of the pancreatic head, 2 patients with intraductal papillary myxoma of the main pancreatic duct of the pancreatic head, 1 patient with duodenal adenoma with high grade intraepithelial neoplasia, 1 patient with metastatic renal clear cell carcinoma of the pancreatic head, 5 patients with soft pancreas, 12 patients with medium texture, 3 patients with hard texture. The diameter of distal pancreatic duct was (2.1±1.7) mm. The operative time was (380±69) min, the duration of pancreaticojejunostomy was (29±15) min, the intraoperative blood loss was (180±150) mL, the postoperative time of anal exhaust (2.2±0.8) d, postoperative time of fluid intake (3.5±1.1) d, postoperative time of half fluid intake (5.5±0.7) d, postoperative time of hospitalization (14±10) d. There were 3 complications in 2 patients, one of which suffered the pulmonary infection, the other suffered the delayed gastric emptying and gastrointestinal anastomosis bleeding, no bile leakage and abdominal hemorrhage happened. There were 2 cases of pancreatic fistula after the operation, all of them were biochemical pancreatic fistula.Conclusions“Double R” pancreaticojejunostomy method has some advantages of convenient operation, short operation time, and low incidence of pancreatic fistula. However, due to the limited sample size, its safety and feasibility still need to be verified by larger samples and more institutions.
ObjectiveTo investigate the role of 3D visualization technology in the laparoscopic precise hepatectomy. MethodsTo retrieve the literatures about the application of 3D visualization technology in laparoscopic precise hepatectomy, and summarize and analyzed them. ResultsThe application of 3D visualization in laparoscopic precise hepatectomy could effectively reduce the operative time, blood loss, blood transfusion rate, and total complication rate. The application of 3D visualization in preoperative evaluation of the resection surface and residual liver volume had been relatively mature. Although many organizations try to use 3D visualization in laparoscopic hepatectomy, such as laser registration and real-time intraoperative navigation, it had not been widely used in clinic because of technical limitations. ConclusionsExisting research results show that, the application of 3D visualization technology in laparoscopic precise hepatectomy can improve the resectability of lesions, increase perioperative safety, but intraoperative navigation is still need to be further developed before it is expected to be widely used in clinical practice. Existing evidence of increased benefit from laparoscopic precise hepatectomy with 3D reconstruction remains limited, and more rigorous randomized controlled trials of large cases are needed to confirm this.
ObjectiveTo explore technical essentials and safety of laparoscopic cholecystectomy (LC) guided by gallbladder ampulla localization on an imaginary clock for cholecystitis.MethodsA retrospective study of 8 707 continuous patients with mild cholecystitis who underwent LC from July 1998 to February 2018 at a single institution was conducted. Among them, 3 168 patients were treated by the traditional LC from July 1998 to February 2007 (a traditional LC group), 5 539 patients were treated by the LC with the guidance of the gallbladder ampulla localization on an imaginary clock from March 2007 to February 2018 (a gallbladder ampulla localization group). The conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury, operative time, intraoperative blood loss, and postoperative hospital stays were compared between the traditional LC group and the gallbladder ampulla localization group.ResultsThere were no significant differences in the gender, age, course of disease, and type of cholecystitis between these two groups (P>0.050). The rates of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury and the operative time, intraoperative blood loss and postoperative hospital stays in the traditional LC group were 3.00% (95/3 168), 0.13% (4/3 168), 0.09% (3/3 168), 0.03% (1/3 168), (43.6±12.6) min, (18.7±3.3) mL, (3.6±2.7) d, respectively, which in the gallbladder ampulla localization group were 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), (32.2±10.5) min, (12.4±3.5) mL, (3.5±2.8) d, respectively. The differences of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding rates, and the operative time and intraoperative blood loss were statistically significant between these two groups (P<0.050). The differences of the bile leakage without bile duct injury rate and postoperative hospital stays were not statistically significant between the two groups (P>0.050).ConclusionThis study shows that gallbladder ampulla localization on an imaginary clock is useful for ductal identification so as to reduce bile duct injury and improve safety of LC in case of no conversion to open surgery.
Laparoscopic anatomical hepatectomy had developed considerably in recent years, but some complex sites of anatomical hepatectomy, such as anatomical resection of the right posterior lobe of the liver, still presented some technical difficulties. Combining the specific perspective of laparoscope and the particular anatomical structure of the right posterior lobe of the liver, we had proposed a strategy of anatomical right posterior lobe resection via cranial-dorsal approach. The right posterior lobe resection plane was defined by point (right hepatic vein root)—by line (ischemic line/right hepatic vein)—by plane (hepatic surface ischemic line and right hepatic vein composition) to achieve precise anatomical resection of the right posterior lobe of the liver, and could reduce intraoperative complications and comply with the principle of tumour-free. Thus, a strategy of anatomical right posterior lobe resection via cranial-dorsal approach might provide a feasible and effective option for right posterior lobectomy of the liver.
Objective To explore feasibility and efficacy of laparoscopic microsurgery by transanal glove port for excision of rectal tumor. Methods Seventeen patients with rectal tumor underwent laparoscopic microsurgery by transanal glove port for local excision of rectal tumor were chosen from March 2015 to March 2016. This device was constructed by using a incision protective sleeve and standard surgical glove. The laparoscopy was used as lighting equipment. The ultrasonic scalpel, operation forceps and lens were separately inserted into the fixed sheath card from the 3 finger gloves. Results The operations of 17 cases were completed successfully. The operative time was 35–90 min with an average 54 min. The closed glove access time was 11 to 26 min with an average 18 min. The diameter of tumor was 1.4–3.5 cm with an average 2.4 cm. The results of postoperative pathology included 8 cases of villos adenemas, 3 cases of high-grade intraepithelial neoplasia, 1 case of low-grade intraepithelial neoplasia, 3 cases of carcinoid , and 2 cases of adenocarcinoma. All resection margins were negative. No infection, intestinal fistula, bleeding, and other complications were found. The hospital stay was 4–9 d with an average of 5 d. No recurrence was found during a follow-up of 1–6 months. Conclusions The preliminary results of limited cases in this study show that laparoscopic microsurgery by transanal glove port for excision of rectal tumor is easy, safe, and effective. It also provides a new choice for individualized comprhensive treatment of rectal tumor.
Objective To explore safety and efficacy of total laparoscopic radical resection of hilar cholangiocarcinoma. Methods From April 2016 and January 2017, 6 patients with hilar cholangiocarcinoma underwent laparoscopic radical resection in the Affiliated Hospital of Xuzhou Medical University were collected. The intra- and post-operative situation and the postoperative complications were analyzed. Results The radical resections of hilar cholangiocarcinoma were completed laparoscopically in all the patients. There was no conversion to the laparotomy. The procedure was finished within a time of (231.3±94.5) min and with an intraoperative blood loss of (123.3±46.8) mL. The first postoperative exhausting time and the postoperative hospital stay was (2.7±0.3) d and (11.9±1.7) d, respectively. All the patients had the R0 resection and the numbers of dissected lymph nodes were 9.4±2.7. The postoperative complications occurred in 2 patients, they were all cured spontaneously in one week, and there was no perioperative death. None of patients had a local recurrence and metastasis during an average 8 months of following-up. Conclusions Preliminary results of limited cases in this study show that with suitable case and skillful laparoscopic technique, laparoscopic radical resection of hilar cholangiocarcinoma is feasible and safe. Further studies are still needed to confirm benefits of this approach.
