ABSTRACT
Objective:To study the feasibility and safety of redo laparoscopic operations for choledochojejunostomy stenosis after minimally invasive pancreaticoduodenectomy.Methods:The clinical data of 7 patients with choledochojejunostomy stenosis which developed after minimally invasive pancreaticoduodenectomy who were treated with redo laparoscopic surgery from August 2019 to July 2021 at the Division of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People's Hospital were retrospectively studied. There were 3 males and 4 females, with the age of (41.7±4.3) (ranged 27 to 54) years. The timing of reoperation, intraoperative blood loss, and postoperative complications were analyzed. An anastomotic restenosis was looked for on followed-up by outpatient interviews or phone calls.Results:The time interval of between diagnosis of the first postoperative anastomotic stenosis and surgery was 3-20 months, with a median of 9 months. Of the 7 patients, 5 patients underwent laparoscopic biliary anastomotic resection and reconstruction, and the remaining 2 patients underwent laparoscopic exploration of the anastomosis, removal of intrahepatic bile duct stones, and re-anastomosis. The median operative time was 180 (150-350) minutes. The median postoperative hospital stay was 6 (ranged 5 to 21) days. The intraoperative blood loss was 50 (ranged 20 to 300) ml. There was no intraoperative blood transfusion. One patient developed grade B biliary leakage after the surgery, improved with puncture and drainage. The remaining patients had no serious complications. There was no mortality. The median follow-up was 8 (ranged 1 to 23) months, during which no recurrence of biliary anastomotic stenosis occurred in all these patients.Conclusion:For patients with biliary anastomotic stenosis after minimally invasive pancreaticoduodenectomy, redo laparoscopic operations offered an alternative treatment option with satisfactory outcomes.
ABSTRACT
This review focused on the progress in laparoscopic pancreaticoduodenectomy(LPD) in the past six years.With the appropriate approaches under laparoscopy, including the resection and reconstruction, LPD has been proved to be safe and feasible. In some centers, LPD has been routine with rapid growth of numbers, it not only benefit the patients with fast recovery, but also benefit the trainees with similar sights as the primary surgeon and good videos of the procedures. However, LPD is still controversial as the more complications in some centers and inconclusive oncologic outcomes. Thus, in the further, a long-time outcome monitoring of LPD is essential. A registry of a prospectively maintained database may be a need for LPD to evaluate its outcomes by multicenter randomized control trials, and real world research may be of value. Structured LPD training programs are valuable for the new surgeons.
ABSTRACT
Objective:To evaluate the effect of multidimensional model of laparoscopic suture training in spread of laparoscopic pancreatic surgery.Methods:The surgeons who took advanced training in Department of Gastroenterology and Pancreatic Surgery in Zhejiang Provincial People’s Hospital from September 2018 to March 2020 were enrolled. Theoretical presentation, simulation training and assessment, clinical practices were included in the multidimensional training model. The " mattress suture" module (2 mattress sutures) in the LAP Mentor laparoscopic advanced simulator was used as the initial assessment and post-training assessment. The average needle loading time, time to form a knot, total time, accuracy rate of precise needle passage through the entrance and exit dots, and total aggressive tissue handing provided in the LAP Mentor were analyzed pre- and post-training. The trained surgeons were followed up for their clinical work in own hospitals.Results:A total of 13 surgeons were trained, including 4 deputy chief physicians, 7 attending physicians over 3 years, and 2 attending physicians under 3 years. The trainees had only primary laparoscopic surgery experience and no laparoscopic pancreatic surgery experience. After training in the above scheme, the average needle loading time was shortened from (93.6±31.6) s to (45.7±13.6) s, and the time to form a knot was reduced from (138.9±46.2) s to (62.1±22.9) s, and total time to accomplish the suture shortened from (15.9±3.8) min to (6.7±3.5) min. The accuracy rate of precise needle passage through the entrance and exit dots increased from (63.7±10.3)% to (89.6±9.8)%. The total aggressive tissue handing decreased from (18.2±12.5) to (6.7±4.9). All those data showed statistical differences ( P<0.05). During follow-up, all traineescan operate the laparoscopic pancreatic surgery proficiently. One trainee completed his first laparoscopic pancreaticoduodenctomy as the primary surgeon, and one trainee complete the splenic vein branch suture to stop hemostasis during laparoscopic pancreatectomy with spleen-preserving spleen, and 3 trainees completed laparoscopic pancreaticoduodenctomy as the first assistant surgeons with good outcomes. Conclusion:Multidimensional model of laparoscopic suture training can improve the trainee's suture skill and help perform complex laparoscopic pancreatic surgery with self-confidence.
ABSTRACT
Laparoscopic pancreaticoduodenectomy (LPD) is technically safe and feasible with advantage of minimally invasive feature, and has become a routine procedure in some minimally invasive pancreatic centers. However, LPD is complicated to be operated and will take a long time to operate proficiently. How to successfully promote LPD application has become a key issue in the new era. This article focuses on the key issues in how to promote LPD application safely in primary hospitals, whether LPD can be used for malignant tumors, and how to cultivate new generation LPD experts.
ABSTRACT
Objective@#To evaluate the accuracy of endoscopic titanium clip localization combined with CT three-dimensional reconstruction for the control of incision margin in early gastric cancer under laparoscopy.@*Methods@#A prospective analysis was made for gastric cancer whose lesions were located in the middle of the stomach and T stage was 1 to 2 from October 2017 to January 2019 at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital. Totally 25 patients were eventually enrolled in the study. There were 17 males and 8 females aging of (63.6±7.2) years (range: 48 to 77 years). All cases were treated with titanium clip localization under endoscope combined with CT three-dimensional(3D) reconstruction to construct a virtual panorama of gastric cavity and lesions, and to design surgical margins. Laparoscopic surgical resection was performed according to the surgical margins designed before operation. The distance from the gastric angle to the origin of the minor curvature of the incisional margin, the distance from the gastric angle to the the center of lesion and the distance of the upper incision margin were measured under three-dimensional CT reconstruction and under actual specimen. Paired t test was used to compare the three distances measured by two methods.@*Results@#The measured distances from the gastric angle to the center of the lesion and the proximal incisional margin under 3D reconstruction CT were according to the measured values of actual specimens ((2.67±1.38) cm vs. (2.83±1.56) cm, t=1.51, P=0.14; (5.23±0.60) cm vs. 5 cm, t=1.93, P=0.07); the measured distances from the gastric angle to the origin of the minor curvature of the incisional margin under CT 3D reconstruction were different with the measured values of solid specimens ((5.94±0.94) cm vs. (6.37±0.90) cm, t=3.52, P=0.00).@*Conclusion@#The method of titanium clip localization combined with CT 3D reconstruction can provide a feasible laparoscopic localization method and incision edge solution for T1 to T2 gastric central cancer.
ABSTRACT
PURPOSE: Our aim was to detect the potential role of interleukin 11 (IL-11) in the development of chemo-resistance in gastric cancer and to reveal the mechanism involved in the process. MATERIALS AND METHODS: Here, we used flow cytometry to examine the percentage of cancer-associated-fibroblasts in tumor samples from chemo-resistant and -sensitive gastric cancer patients. Using MTT assay, we detected the cell viability under different conditions. Using quantitative real-time polymerase chain reaction and Western blotting, we determined the target expressions in mRNA and protein levels. We also performed immunohistochemistry and immunofluorescence to detect the target proteins under different conditions. Animal models were constructed to verify the potential role of IL-11 in chemo-resistant develop in vivo. RESULTS: Herein, we observed enriched cancer associated fibroblasts in drug resistant tumor tissues from gastric patients. Those fibroblasts facilitate the chemotherapeutic drugs resistance development through the secretion of IL-11, which activates the IL-11/IL-11R/gp130/JAK/STAT3 anti-apoptosis signaling pathway in gastric cancer cells. We found that the combination of chemotherapeutic drugs and JAK inhibitor overcomes the resistance and increases the survival of mice with gastric cancer xenografts. CONCLUSION: Ourresults demonstrated that IL-11 contributed to the obtain ofresistance to chemotherapy drugs through gp130/JAK/STAT3/Bcl2 pathway, and targeting the IL-11 signaling pathway induced by fibroblasts might be a promising strategy to overcome the multi-drugs resistant cancer in clinic.

The R0 rate was 100%.The medium follow-up was 10 months.One patient was diagnosed as liver metastasis after 8 months and accepted chemotherapy.One patient died after 14 months for tumor recurrence and metastasis.Others survived without tumor recurrence or metasitasis.@*Conclusion@#Lap-RAMPS is safe and feasible with accepted oncological outcomes for selected left side pancreatic adenocarcinoma under skilled hands.
ABSTRACT
Neuroendocrine tumor of the pancreas (pNET) is a rare group of neoplasms with widely heterogeneity. Complete surgical resection remains the only potentially curative treatment for pNET. Compared to open surgery, minimal invasive approach treating pNET could decrease bleeding and shorten postoperative hospital stay, while didn′t show difference in operation time, postoperative complication rate and overall mortality. Therapeutic strategy was formulated by synthesizing clinical symptoms, tumor size and tumor stage. Minimal invasive approach can achieve radical curve of oncology and provide refine manipulation condition to improve surgical safety and efficacy, meanwhile realize function preservation. Minimal invasive approach is a safe and efficient method in treating pNET, but further prospective, randomized control trials are required.
ABSTRACT
Objective@#To summarize the incidence and characteristics of postoperative complications after laparoscopic pancreaticoduodenectomy(LPD), and to share our experience on management of complications.@*Methods@#The clinical data of 320 LPD performed by a single team in Sir Run Run Shaw Hospital and Zhejiang Provincial People′s Hospital between September 2012 and September 2017 were retrospectively analyzed, among which there were 196 males and 124 females with age of (60.2±11.6) years old.There were 306 patients who underwent standard LPD, and 14 patients who underwent extended LPD. The patients were divided into 2 groups of former 160 LPD and later 160 LPD according to the time order. By analyzing the differences of clinical outcomes between the two groups, especially focusing on the incidence of postoperative complications.The experience on management of complications was concluded. The prior surgical history of latter group was significantly higher than the former group(30.0%(48/160)vs. 18.8%(30/160), χ2=5.49, P=0.019), and the rest of baseline characteristics remained the comparable (P>0.05). For resectable lesions, LPD was performed by "No back" approach, following the principle of "From distal to cephalad, from ventral to dorsal, and from left to right" . As for the borderline resectable patients, LPD was performed by "Easy first" strategy. Student t test, χ2 test or Fisher test was used to analyzed the data between the two groups respectively.@*Results@#Of 320 LPD patients, 306 cases underwent standard LPD, 14 cases underwent LPD with resection of other organs.There were 278 LPD cases who followed "No back" approach, and 42 cases who followed "Easy first" strategy because of difficulty in creating the retro-pancreatic tunnel. And the overall morbidity was 32.2%(103/320) with reoperation rate of 5.3%(17/320). The perioperative mortality was 0.6%(2/320). The operation time of latter group was ((346.6±48.8)minutes), which was shorter than that of former group((358.0±54.4)minutes)(t=1.97, P=0.048). The blood loss of former and latter group remained comparable((207.9±135.8)ml vs.(189.6±121.4)ml, P=0.205). However, in subgroup analysis, the patients with blood loss less <200 ml of latter group decreased significantly from 59.4%(95/160) to 47.5%(76/160)(χ2=4.53, P=0.033). The overall morbidity of latter group was 28.8%(46/160), indicated a decrease from 35.6%(57/160) of former group without significant difference(P=0.188). Moreover, Grade A/B/C pancreatic fistula rate, Grade A/C bile leakage rate, Grade B/C postoperative hemorrhage rate of the later group tended to decrease, although they also didn′t reach a significant difference. However, the abdominal infection rate decreased significantly(χ2=3.93, P=0.047). The length of hospital stay remained comparable(P=0.156).@*Conclusions@#The most common complications after LPD were postoperative hemorrhage and pancreatic fistula. With specialized team and accumulated experience, the morbidity can decrease progressively by analyzing the leading cause and improving the technical skills.

ABSTRACT
Objective To explore the clinical efficacies of open and laparoscopic surgery in the treatment of adult patients with congenital choledochal cyst.Methods The clinical data of 36 adult patients with congenital choledochal cysts who were admitted to the Sir Run Run Shaw Hospital from February 2008 to February 2015 were retrospectively analyzed.Twenty-four patients underwent common bile duct cyst resection + cholecystectomy +biliojejunal Roux-en-Y anastomosis (open surgery group),12 patients underwent laparoscopic common bile duct cyst resection + cholecystectomy + biliojejunal Roux-en-Y anastomosis (laparoscopy group).The intraoperative conditions,detection indexes and postoperative recovery indexes in the 2 groups were analyzed.The follow-up by regular outpatient examination and telephone interview were done up to March 2015.Non-normal distribution data were described as M(P25,P75).Comparison between groups was analyzed using the Mann-Whitney U test and Fisher exact probability.Measurement data with normal distribution were presented as (x) ± s and analyzed using t test.Count data were evaluated by the ratio and proportion.Results The operation time of the open surgery group and laparoscopy group were 238 minutes (191 minutes,283 minutes) and 270 minutes (225 minutes,326 minutes),with a significant difference between the 2 groups (Z =-1.360,P ＞ 0.05).The volume of intraoperative blood loss in the open surgery group and laparoscopy group were 200 mL (113 mL,363 mL) and 75 mL(50 mL,138 mL),with a significant difference between the 2 groups (Z =-3.377,P ＜0.05).The level of C-reactive protein in the open surgery group and laparoscopy group were 94 mg/L (81 mg/L,104 mg/L) and 29 mg/L (21 mg/L,61 mg/L),with a significant difference between the 2 groups (Z =-4.296,P ＜0.05).The pain scores at postoperative day 3,time to anal exsufflation,time for fluid diet intake and duration of hospital stay of the open surgery group and laparoscopy group were 2.5 ± 0.9,(3.7 ± 1.0) days,(5.0 ± 1.6) days,(10.0 ± 2.7) days and 1.9 ±0.3,(2.6 ± 1.0) days,(3.6 ± 1.6) days,(7.8 ± 2.2) days,respectively,showing significant differences between the 2 groups (t =3.146,3.286,2.450,2.523,P ＜ 0.05).Nine patients in the open surgery group and 3 patients in the laparoscopy group had the complications,with improvement of conditions after symptomatic treatment,showing no significant difference between the 2 groups (P ＞ 0.05).All the 36 patients were followed up for a median time of 36 months (range,1-72 months) with good recovery,without long-term postoperative complications and re-operation.Conclusion Laparoscopic surgery in the treatment of adult patients with congenital choledochal cyst is safe and feasible,with the advantages of less intraoperative bleeding,less surgical trauma,fast recovery compared with open surgery.
ABSTRACT
Objective To evaluate the short-and long-term outcomes of laparoscopy-assisted gastrectomy (LAG) for gastric cancer.Methods After studying the patients' demographic data,extent of gastrectomy and lymphadenectomy,as well as differentiation and tumor TNM stage,85 patients who underwent LAG were individually matched to 85 patients who underwent open surgery (OG) between October 2004 and March 2008.The operative time,intraoperative blood loss,postoperative recovery,complications,pathological findings,and follow-up data were compared between the two groups.Results The mean operative time was significantly longer in the LAG group than in the OG group (277 ± 62) min vs.(211 ±46) min,t =7.882,P ＜0.05,whereas intraoperative blood loss was significantly lower (161 ±90) ml vs.(267 ± 141) ml,t =-5.854,P ＜0.05.In addition,there was a significant reduction in the time to first flatus and postoperative hospital stay (3.7 ± 1.3) days vs.(4.2 ± 1.1) days and (10 ± 3) days vs.(12 ± 6) days,respectively t =-2.318,-2.325,P ＜ 0.05.There was no significant difference between the LAG group and OG group with regard to the number of harvested lymph nodes and overall postoperative complications.The 5-year disease-free survival rates and overall survival rates were 76％,78％,respectively,in LAG group and 75％,73％,respectively in OG group (all P ＞ 0.05).Conclusions LAG is suitable and minimally invasive for treating gastric cancer.Compared to OG,the LAG will not increase the risk of recurrence and mortality after surgery.

Objective To evaluate the safety and efficacy of laparoscopy-assisted total gastrectomy (LATG) for gastric cancer by systematic review and meta-analysis.Methods The literature database before February,2012 was extensively searched to retrieve the comparative studies of LATG and open total gastrectomy(OTG) with a relevance of study goal.The inclusion and exclusion criteria were formulated.Aftera quality evaluation,the data was extracted.The Cochrane collaboration RevMan 5.1 version software was used for meta-analysis.Results There are ten studies meeting the inclusion criteria for meta-analysis.The total sample size of these studies was 942 cases.Compared to OTG,LATG experienced longer operation time [weighted mean difference(WMD) =41.12 min,95％ confidence interval(CI):20.62-61.63,P ＜0.01)],less blood loss(WMD =-198.36 ml,95％ CI:-300.94--95.78,P ＜ 0.01),earlier time to flatus(WMD =-0.80 days,95％ CI:-1.17--0.42,P＜0.01),shorter hospital stay(WMD =-4.02days,95％ CI:-6.03--2.01,P ＜ 0.01) and decrease in overall complications [relative risk (RR) =0.55,95％ CI:0.40-0.76,P ＜ 0.01)].The number of dissected lymph nodes,proximal or distal resection margin and mortality were similar between the two groups.Conclusions Laparoscopy-assisted total gastrectomy is a safe and feasible procedure with less blood loss,less overall complications and quick recovery.
ABSTRACT
Objective To summarize our experience in the management of stones impacted at cystic duct during laparoscopic cholecystectomy(LC). Methods There were 58 patients with stones impacted at cystic duct during LC from July 1997 to June 2001.Cystic duct was incised to remove stones first,then intraoperative cholangiography was performed.If stones were found in common bile duct,they would be taken out by intraoperative endoscopic sphincterotomy or open operation. Results All the impacted stones in 58 patients were removed successfully.51 coses underwent LC.Intraoperative cholangiography showed there were common bile duct stones in 7 cases.For these 7 coses,5 cases were treated by LC combined with intraoperative endoscopic sphincterotomy and other 2 cases were converted into open operation.No Severe complication occurred. Conclusions Nearly all cases with stones impacted at cystic duct can receive LC by removing impacted stones through incising the cystic duct and intraoperative cholangiography.If there are any stones in common bile duct,they can be removed by endoscopic sphincterotomy.
