RESUMEN
Objective To investigate the safety and short-term efficacy of π-shaped anastomosis and circular anastomosis(reverse puncture device)in reconstruction of esophagojejunostomy after laparoscopic total gastrectomy.Methods A retrospective study was used to collect the clinical and pathological data of 75 cases of gastric cancer from January 2019 to March 2021.According to the different reconstruction methods of esophagojejunal anastomosis,the patients were divided into a linear cutting obturator group(π-shaped anastomosis group,n = 27)and a circular anastomat anastomosis group(reverse puncture device group,n = 48).The general information of the two groups,operation time,esophagojejunostomy time,intraoperative bleeding volume,number of intraoperative lymph node dissection,intraoperative complications,and postoperative complications were compared and analyzed.Results The operation time and esophagojejunostomy time in the π-shaped anastomosis group were(221.5±8.8)and(34.7±3.7)min,and the reverse puncture device group were and(246.9±5.6)and(47.2±4.6)min,respectively,the differences were statistically significant(t = 15.19,t = 11.81,P＜0.05).There were no statistical significance in the comparison of intraoperative bleeding volume and number of intraoperative lymph node dissection between the two groups(P＞0.05).In the reverse puncture device group,there were two intraoperative complications,including one case of esophageal jejunal anastomosis atresia and one case of anastomosis tear,postoperative complications occurred in 3 cases,postoperative anastomotic stenosis occurred in 2 case,and anastomotic bleeding occurred in 1 case.Conclusion Laparoscopic total esophagojejunostomy with π-shaped anastomosis and reverse puncture device are safe and feasible.In terms of esophagojejunostomy time,π-shaped anastomosis reconstruction time is shorter.When the small intestine diameter is relatively small and it is difficult to extend into the 25 mm stapler,the advantage of π-shaped anastomosis is more obvious.When the tumor is Siewert type Ⅰ and type Ⅱ adenocarcinoma of gastroesophageal junction,which infiltrates into above the dentate line,reverse puncture device method is recommended for reconstruction.
RESUMEN
Objective:To investigate the clinical value of esophageal-jejunal OrVil TM anas-tomosis and Overlap anastomosis in laparoscopic radical total gastrectomy of adenocarcinoma of esophagogastric junction (AEG). Methods:The retrospective cohort study was conducted. The clinicopathological data of 112 patients with AEG who were admitted to the First Hospital of Jilin University from July 2017 to August 2022 were collected. There were 87 males and 25 females, aged (64±8)years. All 112 patients underwent laparoscopic total gastrectomy and D 2 lymphadenectomy, in which 61 cases with esophageal-jejunal OrVil TM anastomosis were divided into the OrVil TM group, 51 cases with esophageal-jejunal Overlap anastomosis were divided into the Overlap group. Observa-tion indicators: (1) surgical situations; (2) postoperative complications; (3) influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. Results:(1) Surgical situations. The esophageal invasion length and tumor diameter was 1.0(0.7,2.0)cm and (6.3±2.7)cm in patients of the OrVil TM group, versus 0.2(0.1,0.5)cm and (4.7±2.2)cm, respectively, in patients of the Overlap group, showing significant differences in the above indicators between the two groups ( Z=?6.14, t=3.26, P<0.05). (2) Postoperative complications. Cases with complications ≥Ⅲa grade of Clavien-Dindo classification, cases with respiratory system complications, cases with hydrothorax were 13, 17, 13 in the OrVil TM group, versus 4, 5, 4 in the Overlap group, showing significant differences in the above indicators between the two groups ( χ2=3.91, 5.74, 3.91, P<0.05). Cases underwent readmission within postoperative 30 days were 3 and 1 in the OrVil TM group and the Overlap group, respectively, and all patients recovered after symptomatic treatment. There were 2 cases died after operation in the OrVil TM group and none of patients died after operation in the Overlap group. (3) Influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Results of multivariate analysis showed that esophageal invasion length was an independent factor influencing for patients undergoing esophageal-jejunal OrVil TM anastomosis ( odds ratio=8.25, 95% confidence interval as 3.41?19.96, P<0.05). Conclusions:Compared with esophageal-jejunal Overlap anastomosis, choosing the esophageal-jejunal Orvil TM anastomosis during laparoscopic radical total gastrectomy can take benefit to the proximal margin of patients with AEG. However, the ratios of complications ≥ Ⅲa grade of Clavien-Dindo classification, respiratory system complications and hydrothorax associated to OrVil TM anastomosis are relatively increased. Esophageal invasion length is an independent influencing factor for patients undergoing esophageal-jejunal OrVil TM anastomosis.
RESUMEN
Objective:To investigate the short-term efficacy of laparoscopic total gastrec-tomy with hand-sewn esophagojejunostomy versus Roux-en-Y anastomosis.Methods:The propen-sity score matching and retrospective cohort study was conducted. The clinicopathological data of 159 patients who underwent laparoscopic total gastrectomy in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from October 2014 to July 2021 were collected. There were 107 males and 52 females, aged 63(range, 28?79)years. Of 159 patients, 71 cases undergoing totally laparoscopic total gastrectomy with hand-sewn esophagojejunostomy were allocated into totally laparoscopic group and 88 cases undergoing laparoscopic-assisted total gastrectomy with Roux-en-Y anastomosis were allocated into laparoscopic-assisted group, respectively. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and postoperative conditions; (3) perioperative complications. Propensity score matching was done by the 1:1 nearest neighbor matching method. Measurement data with normal distribution were expressed as Mean± SD, and t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M(range), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher's exact probability method. The rank sum test was used for comparison of ordinal data. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of 159 patients, 112 cases were successfully matched, including 56 cases in the totally laparoscopic group and 56 cases in the laparoscopic-assisted group. Before propensity score matching, age, cases with tumor located in cardia or gastric body in the totally laparoscopic group were 61(range, 30?76)years, 26, 45, respectively. The above indicators in the laparoscopic-assisted group were 65(range, 28?79)years, 50, 38, respectively. There were significant differences in the above indicators between the two groups ( Z=?2.89, χ2=6.43, P<0.05). After propensity score matching, the males and females, age, body mass index, cases of American Society of Anesthesiologists classification Ⅰ, Ⅱ, Ⅲ and Ⅳ, tumor diameter, cases with tumor located in cardia or gastric body, cases in TNM stage Ⅰ, Ⅱ and Ⅲ of patients in the totally laparoscopic group were 40, 16, (62±9)years, (22.7±2.8)kg/m 2, 22, 26, 7, 1, 3.5(range, 0.6?17.0)cm, 24, 32, 22, 9, 25. The above indicators of patients in the laparoscopic-assisted group were 38, 18, (62±10)years, (22.7±3.2)kg/m 2, 19, 32, 5, 0, 4.0(range, 0.6?15.0)cm, 23, 33, 21, 7, 28, respectively. There was no significant difference in the above indicators between the two groups ( χ2=0.17, t=?0.09, ?0.04, Z=?0.12, ?0.82, χ2=0.04, Z=?0.42, P>0.05). The elimination of age and tumor location confounding bias ensured comparability between the two groups. (2) Intraoperative and postoperative conditions: after propensity score matching, the total operation time, time of esophagojejunostomy, postopera-tive 24-hour pain numerical score and time to first out-off bed activities were (310±49)minutes, (37±10)minutes, 2.3±0.8 and (2.4±0.7)days for patients in the totally laparoscopic group, versus (344±77)minutes, (44±12)minutes, 3.1±1.2 and (2.9±1.0)days in the laparoscopic-assisted group, showing significant differences between the two groups ( t=?2.85, ?3.05, ?4.20, ?3.10, P<0.05). (3) Perioperative complications: after propensity score matching, 6 cases of the patients in the totally laparoscopic group had Clavien-Dindo grade 2 or higher complications, including 2 cases of anas-tomotic leak, 1 case of anastomotic stenosis, 1 case of pleural effusion, 1 case of abdominal infection and 1 case of intestinal obstruction. The incidence of Clavien-Dindo grade 2 or higher complications was 10.7%(6/56). In the laparoscopic-assisted group, 5 patients had Clavien-Dindo grade 2 or higher complications, including 2 cases of anastomotic leak, 1 case of abdominal infection, 1 case of intestinal obstruction and 1 case of cholangitis. The incidence of Clavien-Dindo grade 2 or higher complications was 8.9%(5/56). There was no significant difference in the incidence of Clavien-Dindo grade 2 or higher complications between the two groups ( χ2=0.10, P>0.05). Patients with anas-tomotic leak were improved after puncture and drainage, secondary surgery and conservative treat-ment, and other complications were improved after symptomatic treatment. Conclusions:Com-pared with Roux-en-Y anastomosis in laparoscopic total gastrectomy, the time of hand-sewn esophagojejunostomy and esophago-jejunal anastomosis are shorter, patients have less postopera-tive pain and faster postoperative recovery. Both methods have good peri-operative safety.
RESUMEN
PURPOSE: The overlap method is one of the most popular procedures for construction of an esophagojejunostomy and its common entry is usually closed with sutures. This study aimed to report long-term complications and surgical outcomes of the overlap method with stapled closure (OMSC), to compare them with those of laparoscopy-assisted total gastrectomy (LATG), and to analyze a learning curve.METHODS: Between January 2015 and August 2017, 100 consecutive patients underwent laparoscopic total gastrectomy with OMSC for gastric cancer and the patients' medical records were reviewed. Their clinicopathologic characteristics, surgical outcomes, and long-term complications were investigated and compared with those of the LATG group. A learning curve of OMSC was analyzed using the Exponentially Weighted Moving Average chart.RESULTS: The overall duration of surgery was shorter in the LATG group; however, there was no difference in patients with early gastric cancer. Hospital admission was shorter and the pain scale was lower in the OMSC group. There was no difference in the number of harvested lymph nodes, date of flatus, or incidence of postoperative morbidity. Both groups showed no duodenal stump leakage, anastomosis-related complications, recurrence, or mortality during the follow-up period. Petersen hernia was a notable long-term event following OMSC compared with LATG. At least 27 cases of surgery were required to reach a plateau in terms of surgery duration for OMSC.CONCLUSION: OMSC is a safe option for the treatment of gastric cancer and has favorable long-term results and surgical outcomes. Closure of mesenteric defects and Petersen space should be considered.

OBJECTIVE: To identify the risk factors of esophagojejunal anastomotic leakage and its intervention measures of gastric cancer patients after laparoscopic total gastrectomy. METHODS: The clinical and follow-up data of 440 gastric cancer patients who underwent laparoscopic total gastrectomy with negative margins at the Department of General Surgery, Nanfang Hospital of Southern Medical University from April 2006 to December 2016 were analyzed retrospectively. Risk factors of esophagojejunal anastomotic leakage and intervention measures of patients were analyzed respectively. RESULTS: Esophagojejunal anastomotic leakage occurred in 12 of 440 patients(2.7%). The leakage was diagnosed at a median of 4(range,1 to 8) days after surgery. Univariate analysis showed that gender, age, neoadjuvant chemotherapy, anastomosis method, combined organ resection, invasion of the esophagus were risk factors affecting esophagojejunal anastomotic leakage after laparoscopic total gastrectomy, with statistically significant differences(P<0.05). Multivariate analysis showed that age, neoadjuvant chemotherapy, anastomosis method, combined organ resection,invasion of the esophagus were independent risk factors affecting esophagojejunal anastomotic leakage after laparoscopic total gastrectomy, with statistically significant differences(P<0.05). CONCLUSION: For the elderly patients, who are older than 65 years old, received neoadjuvant chemotherapy, had tumor invasion of the esophagus, undergone total laparoscopic anastomosis, combined organ resection, when they are treating with laparoscopic total gastrectomy, esophagojejunal anastomosis should be careful about. Esophagojejunal anastomotic leakage can be treated effectively with self-expanding metalstents, but the risk of migration still exists.
RESUMEN
PURPOSE: To present the feasibility and safety of Roux-en-Y esophagojejunostomy using hemi-double-stapling technique after laparoscopic total gastrectomy. METHODS: We reviewed the outcomes from 58 consecutive patients with gastric cancer who underwent laparoscopic total gastrectomy. The clinicopathological characteristics including postoperative complications were examined. RESULTS: The mean age and body mass index were 57.3 ± 9.7 years and 23.7 ± 2.6 kg/m², respectively. The mean overall total operation was 199.8 ± 57.0 minutes. Intraoperative blood loss was 81.6 ± 56.3 mL and there was no open conversion. The patients' hospital stay was a mean 9.6 ± 2 days. The mean proximal margin of the specimens was 2.7 ± 1.8 cm. There were 3 cases (5.1%) of anastomosis leakage, but all were controlled successfully by endoscopic stent. CONCLUSION: The circular HDST technique is simple and reliable without any significant demerits with respect to safety concerns or difficulty of operation.

Laparoscopic gastrectomy has become widely used as a minimally invasive technique for the treatment of gastric cancer. When it was first introduced, most surgeons preferred a laparoscopic-assisted approach with a minilaparotomy rather than a totally laparoscopic procedure because of the technical challenges of achieving an intracorporeal anastomosis. Recently, with improved skills and instruments, several surgeons have reported the safety and feasibility of a totally laparoscopic gastrectomy with intracorporeal anastomosis. This review describes the recent technical advances in intracorporeal anastomoses using circular and linear staplers that allow for totally laparoscopic distal, total, and proximal gastrectomies. Data that demonstrate advantages in early surgical outcomes of a total laparoscopic method compared to laparoscopic-assisted operations are also discussed.

PURPOSE: Because no effective methods for performance of anastomosis have been established, use of laparoscopic total gastrectomy (LTG) has not been widely accepted. We aimed to establish the feasibility of using a newly developed purse-string suture instrument ("Lap-Jack"), which can be used in performance of intracorporeal anastomosis. METHODS: From April, 2010 to February, 2011, 50 patients with upper gastric cancer underwent LTG with intracorporeal Roux-en-Y esophagojejunostomy using the Lap-Jack. Retrospective data for gender, age at the time of surgery, past medical history, operative time, estimated blood loss, TNM staging, and postoperative complications were reviewed. RESULTS: Among the 50 patients, 33 were male and 17 were female. Median age was 59.9 years. The average operative time was 217.4+/-41.7 minutes. Based on the AJCC 7th edition of Gastric Cancer Staging, 19 patients were stage IA, three patients were IB, 12 patients were II, one patient was IIIA, three patients were IIIB, eight patients were IIIC, and two patients were IV. The overall morbidity rate was 18.0% without any mortality. Complications included wound problems (2.0%, n=1), pleural effusion (2.0%, n=1), urinary retention (4.0%, n=2), efferent loop obstruction due to adhesion (4.0%, n=2), postoperative ileus (2.0%, n=1), postoperative bleeding (2.0%, n=1), and intra-abdominal abscess (2.0%, n=1). No leakage or stenosis of esophagojejunostomy was reported. CONCLUSION: The Lap-Jack is feasible and suitable for use in performance of esophagojejunostomy during LTG.

PURPOSE: We wanted to evaluate the technical feasibility and safety of totally laparoscopic total gastrectomy (TLTG) for treating early gastric cancer. MATERIALS AND METHODS: The medical records of 11 consecutive patients who underwent TLTG after being diagnosed with early gastric cancer at Incheon St. Mary's Hospital, The Catholic University of Korea from February 2005 to September 2009 were retrospectively reviewed and their clinicopathologic characteristics and the surgical results were investigated. RESULTS: The mean operation time was 385.6+/-94.1 minutes, the mean time for creating an intracorporeal anastomosis was 97.5+/-60.0 minutes and the mean number of the harvested lymph nodes was 46.6+/-15.4. The mean number of days after operation until starting a liquid diet was the 6.15+/-7.6th postoperative day and the mean hospital stay after surgery was 14.2+/-11.9 days. There was no case of open conversion, but there were 2 cases of intraoperative complication and 3 cases of postoperative complication. There was one case of postoperative mortality. The patient suffered from thrombocytopenia of an unknown cause, which was refractory to platelet transfusion, on 4th postoperative day and the patient died of intraabdominal bleeding on the 6th postoperative day. CONCLUSION: TLTG was a technically feasible and relatively safe procedure. However, a long time for creating the intracoproeal anastomosis and a long operation time are still problems to be solved.
