Totally laparoscopic total gastrectomy using intracorporeally hand-sewn esophagojejunostomy

Application of hand-sewn esophagojejunostomy in laparoscopic total gastrectomy

OBJECTIVE

To investigate the clinical efficacy and prognostic implication of hand-sewn anastomosis in laparoscopic total gastrectomy (LTG).

METHODS

Retrospective analysis is adopted to the clinicopathologic data of 112 patients with gastric cancer (GC) who went through LTG in the Department of General Surgery, the Second Affiliated Hospital of Anhui Medical University between October 2020 and October 2022. Among them, 60 individuals receiving medical care were split into the hand-sewn anastomosis group (Group H, N = 60); while, 52 individuals were split into the circular stapler anastomosis group (Group C, N = 52) The clinical efficacy and prognostic conditions of hand-sewn anastomosis are compared with those of circular stapler anastomosis in the application of LTG.

RESULTS

The analysis results indicated that no notable difference was observed in intraoperative bleeding volume, time to first flatus (TFF), postoperative hospitalization duration and postoperative complications among the two groups (P > 0.05). Group H had shorter esophagojejunal anastomosis duration (20.0 min vs. 35.0 min) and surgery duration (252.6 ± 19.4 min vs. 265.9 ± 19.8 min), smaller incisions (5.0 cm vs. 10.5 cm), and lower hospitalization costs (58415.0 CNY vs. 63382.5 CNY) compared to Group C (P < 0.05).

CONCLUSION

The clinical efficacy and the postoperative complications of hand-sewn esophagojejunostomy are basically equivalent in comparison to the circular stapler anastomosis in the application of LTG. Its advantage lies in shorter esophagojejunal anastomosis duration, shorter surgery duration, smaller incisions, lower hospitalization costs and wider adaptability of the location of the tumor.

Comparison of short-term and long-term clinical effects of modified overlap anastomosis and conventional incision-assisted anastomosis in laparoscopic total gastrectomy

BACKGROUND

To compare short-term and long-term clinical effects of modified overlap anastomosis and conventional incision-assisted anastomosis for laparoscopic total gastrectomy.

METHODS

This retrospective cohort study included patients with gastric cancer admitted to the Second Affiliated Hospital of Fujian Medical University from January 2016 to March 2020. Quality of life, intraoperative and postoperative conditions were analyzed.

RESULTS

Compared with the conventional assisted group, the modified overlap group showed a shorter auxiliary incision, milder postoperative pain, shorter time to the first postoperative anal exhaust, shorter time to the first postoperative liquid food intake, and shorter postoperative stay. There were no differences between the two groups regarding operation time, esophagus-jejunum anastomosis time, intraoperative blood loss, number of lymph nodes dissected, and length of the upper incision margin. There were no differences between the two groups regarding postoperative early and late complications. There were no differences between the two groups regarding the QLQ-C30 scale three years after the operation. The scores of the QLQ-STO22 scale 3 years after the operation showed significantly lower scores for dysphagia and feeding limit in the modified overlap group than those in the conventional assisted anastomosis group. There was no recurrence in the modified overlap group but one patient in the conventional assisted group.

CONCLUSIONS

Patients undergoing totally laparoscopic total gastrectomy with modified overlap anastomosis have better minimal invasiveness and faster post-operative recovery than conventional incision-assisted anastomosis.

Hand-sewn esophagojejunostomy in transthoracic single-port assisted laparoscopic esophagogastrectomy for Siewert type II adenocarcinoma of the esophagogastric junction with esophageal invasion > 3 cm

BACKGROUND

An optimal method for digestive tract reconstruction (DTR) in laparoscopic radical resection of Siewert type II adenocarcinoma of esophagogastric junction (AEG) has not yet been standardized. The aim of this study was to evaluate the safety and feasibility of a hand-sewn esophagojejunostomy (EJ) technique during transthoracic single-port assisted laparoscopic esophagogastrectomy (TSLE) for Siewert type II AEG with esophageal invasion > 3 cm.

METHODS

The perioperative clinical data and short-term outcomes for patients who underwent TSLE using hand-sewn EJ for Siewert type II AEG with esophageal invasion > 3 cm between March 2019 and April 2022 have been retrospectively reviewed.

RESULTS

A total of 25 patients were eligible. All 25 patients were successfully operated. None was converted to open surgery or mortality. 84.00% of patients were male and 16.00% were female. The mean age, body mass index (BMI), and the American Society of Anesthesiologists (ASA) score were 67.88 ± 8.10 years, 21.30 ± 2.80 kg/m², and 2.08, respectively. The average incorporated operative and hand-sewn EJ procedural times were 274.92 ± 57.46 and 23.36 ± 3.00 min, respectively. The length of extracorporeal esophageal involvement and proximal margin was 3.31 ± 0.26 cm and 3.12 ± 0.12 cm, respectively. The average time for the first oral feeding and hospital stay were 6 (3-14) and 7 (3-18) days, respectively. Two patients (8.00%) developed postoperative grade IIIa complications according to the Clavien-Dindo classification, including 1 case of pleural effusion and 1 case of anastomotic leakage, both of whom were cured by puncture drainage.

CONCLUSION

Hand-sewn EJ in TSLE is safe and feasible for Siewert type II AEG. This method can ensure safe proximal margins and could be a good option with an advanced endoscopic suture technique for type II tumor with esophageal invasion > 3 cm.

Feasibility and Short-Term Outcomes of Three-Dimensional Hand-Sewn Esophago-Jejunal Anastomosis in Completely Laparoscopic Total Gastrectomy for Cancer

Laparoscopic total gastrectomy is on the rise. One of the most technically demanding steps of the approach is the construction of esophago-jejunal anastomosis. Several laparoscopic anastomotic techniques have been described, like linear stapler side-to-side or circular stapler end-to-side anastomosis; limited data exist regarding hand-sewn esophago-jejunal anastomosis. The study took place between January 2018 and June 2021. Patients enrolled in this study were adults with proximal gastric or esophago-gastric junction Siewert type III tumors that underwent 3D-assisted laparoscopic total gastrectomy. A hand-sewn esophago-jejunal anastomosis was performed in all cases laparoscopically. Forty consecutive cases were performed during the study period. Median anastomotic suturing time was 55 min, with intra-operative methylene blue leak test being negative in all cases. Median operating time was 240 min, and there were no conversions to open. The anastomotic leak rate and postoperative stricture rate were zero. The 30- and 90-day mortality rates were zero. Laparoscopic manual esophago-jejunal anastomosis utilizing a 3D platform in total gastrectomy for cancer can be performed with excellent outcomes regarding anastomotic leak and stricture rate. This anastomotic approach, although technically challenging, is safe and reproducible, with prominent results that can be disseminated in the surgical community.

Application value of hand-sewn anastomosis in totally laparoscopic total gastrectomy for gastric cancer

Background

Digestive tract reconstruction in totally laparoscopic total gastrectomy can be divided into two types: instrument anastomosis and hand-sewn anastomosis. This study explored the feasibility and safety of hand-sewn sutures in esophagojejunostomy of totally laparoscopic total gastrectomy, compared with instrument anastomosis using an overlap linear cutter.

Methods

This retrospective cohort study was conducted from January 2017 to January 2020 at one institution. The clinical data of 50 patients who underwent totally laparoscopic total gastrectomy, with an average follow-up time of 12 months, were collected. The clinicopathologic data, short-term survival prognosis, and results of patients in the hand-sewn anastomosis (n=20) and the overlap anastomosis (n=30) groups were analyzed.

Results

There were no significant differences between the groups in sex, age, body mass index, American Society of Anesthesiologists score, tumor location, preoperative complications, abdominal operation history, tumor size, pTNM stage, blood loss, first postoperative liquid diet, exhaust time, or postoperative length of hospital stay. The hand-sewn anastomosis group had a significantly prolonged operation time (204±26.72min versus 190±20.90min, p=0.04) and anastomosis time (58±22.0min versus 46±15.97min, p=0.029), and a decreased operation cost (CNY 77,100±1700 versus CNY 71,900±1300, p<0.0001). Postoperative complications (dynamic ileus, abdominal infection, and pancreatic leakage) occurred in three patients (15%) in the hand-sewn anastomosis group and in four patients (13.3%) in the overlap anastomosis group (anastomotic leakage, anastomotic bleeding, dynamic ileus, and duodenal stump leakage).

Conclusion

The hand-sewn anastomosis method of esophagojejunostomy under totally laparoscopic total gastrectomy is safe and feasible and is an important supplement to linear and circular stapler anastomosis. It may be more convenient regarding obesity, a relatively high position of the anastomosis, edema of the esophageal wall, and short jejunal mesentery.

Predominant classic circular-stapled double-tract reconstruction after totally laparoscopic proximal gastrectomy: safe, feasible, time-saving anastomoses by technical tie-up

BACKGROUND

The double-tract reconstruction (DTR) could be a preferable option in avoiding the postoperative esophageal reflux and anastomotic stenosis during totally laparoscopic proximal gastrectomy (TLPG). An optimal procedure to achieve the DTR in TLPG remains to be established.

METHODS

During March 2018 to April 2019, 15 consecutive patients with gastric cancer in the upper third of the stomach underwent intracorporeal DTR after TLPG at our hospital. The intracorporeal esophagojejunostomy (E-J), gastrojejunostomy (G-J) and jejunojejunostomy (J-J) were, respectively, performed using circular staplers by the Self-Pulling and Holding Purse-String Suture Technique, Intraluminal Poke Technique and U-shaped Parallel Purse-string Suture Technique (Technical Tie-Up). Demographic and clinicopathologic characteristics, perioperative details and postoperative outcomes were analyzed.

RESULTS

The mean operating time was 216.1 ± 18.2 min. Total time for three anastomoses was 49.8 ± 6.1 min, and the time for E-J, G-J, J-J was 22.4 ± 5.0 min, 13 (range 11-16) min, 14.2 ± 2.8 min, respectively. The median proximal and distal resection margins were 2.5 (range 2-4) cm and 6 (range 5-7) cm, respectively, which were all tumor-free in 15 patients. No major complications and mortality occurred. During the median follow-up period of 14 months (range 7 to 20.5 months), there were no postoperative anastomosis-related complications observed, such as anastomotic bleeding, leakage or stenosis. No patients complained the symptoms indicating esophageal reflux and remnant gastritis.

CONCLUSIONS

Predominant classic circular-stapled double-tract reconstruction is safe, feasible and time-saving in TLPG by the technical tie-up.

Esophageal Suspension Method for Hand-Sewn Esophagojejunostomy After Totally Laparoscopic Total Gastrectomy: A Simple, Safe, and Feasible Suturing Technique

Background: Totally laparoscopic total gastrectomy (TLTG) not only is difficult to operate but also has high technical requirements and a long learning curve. Therefore, it has not been widely carried out yet, and esophagojejunostomy is one of its difficulties. Relevant studies have shown that intracorporeal hand-sewn esophagojejunostomy is safe, feasible and low-cost, but it is complicated and time-consuming and requires a high-suture technique. This study introduces a simple, safe and feasible hand-sewn technique.

Methods: The clinical data of 32 patients with the esophageal suspension method for hand-sewn esophagojejunostomy (suspension group) after TLTG were collected from February 2018 to June 2019. During the same period, 32 patients with traditional hand-sewn esophagojejunostomy (traditional group) after TLTG were used as the control group.

Results: The operative time, anastomosis time, exhaust time and hospitalization time of the suspension group were shorter than those of the traditional group. The intraoperative blood loss in the suspension group was less than that in the traditional group. There were no postoperative complications associated with the suspension group.

Conclusion: For those who have some experience in laparoscopic suture technique, the esophageal suspension method for hand-sewn esophagojejunostomy after TLTG is a simple, safe, and feasible suture technique.

Laparoscopic gastrectomy using intracorporeally hand-sewn anastomosis of esophagojejunostomy, gastroduodenostomy, or gastrojejunostomy for gastric cancer

Laparoscopic gastrectomy (LG) using intracorporeal anastomosis has recently become more prevalent due to the advancements of laparoscopic surgical instruments. However, intracorporeally hand-sewn anastomosis (IHSA) is still uncommon because of technical difficulties. In this study, we evaluated various types of IHSA following LG with respect to the technical aspects and postoperative outcomes.Seventy-six patients who underwent LG using IHSA for treatment of gastric cancer between September 2014 and June 2018 were enrolled in this study. We described the details of IHSA in step-by-step manner, evaluated the clinicopathological data and surgical outcomes, and summarized the clinical experiences.Four types of IHSA have been described: one for total gastrectomy (Roux-en-Y) and 3 for distal gastrectomy (Roux-en-Y, Billroth I, and Billroth II). The mean operation time and anastomotic time was 288.7 minutes and 54.3 minutes, respectively. Postoperative complications were observed in 13 patients. All of the patients recovered well with conservative surgical management. There was no case of conversion to open surgery, anastomotic leakage, or mortality.LG using IHSA was safe and feasible and had several advantages compared to mechanical anastomosis. The technique lengthened operating time, but this could be mitigated by increased surgical training and experience.

Comparison of totally laparoscopic total gastrectomy and laparoscopic-assisted total gastrectomy: A systematic review and meta-analysis

BACKGROUND

Laparoscopic-assisted total gastrectomy (LATG) has been extensively employed for the removal of gastric tumors, although it has several limitations. Totally laparoscopic total gastrectomy (TLTG) is a new technique that has rapidly been gaining popularity, and may help overcome the limitations of LATG; however, its safety and therapeutic effect remain controversial. In the present study, we aimed to assess the safety and efficacy of TLTG, and compare the short-term outcomes of TLTG and LATG.

METHODS

We searched for studies comparing TLTG and LATG published up to April 2018 from databases such as PubMed and Embase. The study results, including time of surgery, blood loss, anastomosis time, retrieved lymphatic nodes, proximal and distal resection edges, incision length, time to first fluid and soft diet, hospitalization duration, time to first flatus, and postsurgical and anastomotic complications, were compared between the procedures.

RESULTS

A total of 10 studies were included. TLTG led to reduced intraoperative blood loss (P < 0.01), greater number of retrieved lymphatic nodes (P < 0.01), decreased hospitalization duration (P < 0.01), reduced incision length (P = 0.05), and shorter time to first fluid diet (P < 0.05), as compared to LATG. The surgery and anastomosis times, time to first soft diet, resection edge, time to first flatus, overall postsurgical complications, and anastomosis-related complications were similar between TLTG and LATG (P > 0.05).

CONCLUSIONS

TLTG is a safe procedure that yields better cosmesis lower invasiveness, and faster recovery as compared to LATG.

Intra-corporeal hand-sewn esophagojejunostomy is a safe and feasible procedure for totally laparoscopic total gastrectomy: short-term outcomes in 100 consecutive patients

BACKGROUND

An optimal method for intracorporeal esophagojejunostomy has not yet been standardized. This study sought to introduce intracorporeal hand-sewn end-to-side esophagojejunostomy after totally laparoscopic total gastrectomy.

METHODS

The author conducted a consecutive series of 100 intracorporeal hand-sewn esophagojejunostomies after totally laparoscopic total gastrectomy for upper third gastric cancer from September 2012 to December 2016.

RESULTS

All patients were successfully operated on without conversion to open- or laparoscope-assisted surgery. The mean reconstruction time was 45 min, and the time until first flatus was 4 days. The time to start a soft diet was 7 days. The length of postoperative hospital stay was 8 days. The overall postoperative morbidity was 8%, including one anastomotic leak, and the mortality was zero. The median follow-up duration was 13 months; no anastomotic strictures were encountered.

CONCLUSIONS

Intracorporeal hand-sewn end-to-side esophagojejunostomy after totally laparoscopic total gastrectomy is a safe and feasible procedure. This method can identify negative margins with intraoperative frozen sections before reconstruction and could be a good option for performing intracorporeal esophagojejunostomy with an advanced endoscopic suture technique.

Totally laparoscopic versus open total gastrectomy for gastric cancer: A case-matched study about short-term outcomes

Although surgical outcomes of totally laparoscopic total gastrectomy (TLTG) have been reported from several centers, the effectiveness of this technique has not been conclusively established. The aim of this study was to investigate the feasibility, safety, and efficacy of TLTG for gastric cancer.A prospectively collected and retrospectively analyzed data were used by comparing the short-term surgical outcomes of 124 patients who underwent TLTG with those of 124 patients who underwent open total gastrectomy (OTG) between March 2007 and March 2016.The 2 groups were well matched with respect to age, sex, body mass index, ASA score, and tumor stage. There was no significant difference with regard to the operation time but TLTG showed significantly less intraoperative blood loss (115.5 ± 70.2 vs 210.5 ± 146.7 mL, P < .01). Total numbers of retrieved lymph nodes were similar in the 2 groups. Postoperatively, no significant differences were found for morbidity or mortality. The time to first flatus, initiate oral intake, and postoperative hospital stay were significantly shorter in the TLTG group than in the OTG group (3.2 ± 1.0 vs 4.1 ± 1.2 days; 4.4 ± 1.2 vs 5.6 ± 2.0 days; and 8.9 ± 3.1 vs 11.3 ± 4.5 days, respectively; P < .01).TLTG for gastric cancer is technically safe, feasible, and minimally invasive compared with OTG. A prospective randomized trial is needed to establish the value of TLTG.

Reconstruction after LATG: technical tips and pitfalls

Since the launching of laparoscopic radical gastrectomy in 1990s, the technique of laparoscopy has become more mature, and it has gradually been applied from distal gastrectomy to total gastrectomy. Laparoscopic distal gastrectomy is an accepted option for gastric cancer surgery; however, laparoscopic total gastrectomy is not widely performed, because of the difficulty of reconstruction of the digestive tract. Efforts have been made to establish an intracorporeal anatomic technique for esophagojejunostomy. There have been several techniques for esophagojejunostomy reported using either circular or lineal staplers. This article is to introduce these techniques and try to analysis the technical tips and pitfalls of them.

Intracorporeal Circular Stapled Esophagojejunostomy Using Conventional Purse-String Suture Instrument After Laparoscopic Total Gastrectomy

BACKGROUND

An optimal alimentary tract reconstruction technique after laparoscopic total gastrectomy (LTG) remains controversial. The authors developed a new simple technique for intracorporeal esophagojejunal anastomosis that employs a conventional purse-string suture instrument (PSI) and circular stapler.

METHODS

From May 2014 to April 2016, 41 consecutive patients with gastric cancer underwent LTG in the author's institution. Intracorporeal esophagojejunal anastomosis using the following method was attempted for all patients. After total gastrectomy was completed laparoscopically, a small vertical incision (about 40 mm) was created at the left midclavicular line and retracted by a wound retractor. An anvil of a 25 mm circular stapler was introduced into the abdominal cavity. Then a previously prepared surgical glove, which was cut open at the thumb and the little finger through which the two hand shafts of the PSI were passed separately and sealed by ties, was attached to the wound retractor to maintain airtightness, and the PSI was introduced into the abdominal cavity. The following procedure was similar to conventional open surgery except that it was performed under laparoscopic vision.

RESULTS

Intracorporeal esophagojejunal anastomosis was performed successfully for all 41 patients. No case required extension of the initial incision for difficulties during anastomosis. The mean operation time was 245 minutes, and the mean time for the purse-string suture and anvil placement was 15 minutes. Tumor-free margins were achieved in all 41 patients. There were no anastomosis-related complications or other major surgical complications.

CONCLUSIONS

With the described method, intracorporeal esophagojejunal anastomosis can be performed easily and safely.

Technical Feasibility and Short-Term Outcome of Intracorporeal Hand-Sewn Esophagojejunostomy After Laparoscopic Total Gastrectomy: Our Experience

The purpose of this study was to demonstrate the safety and technical feasibility of intracorporeal hand-sewn esophagojejunostomy after laparoscopic total gastrectomy. Laparoscopic total gastrectomy (LTG) is a technically challenging procedure, especially for esophagojejunal anastomosis (EJA). Various techniques have been described to overcome these difficulties using staplers with variable results. We report successfully performed complete intracorporeal hand-sewn EJA after LTG. The perioperative clinical data and short-term outcomes for 30 patients who underwent LTG using hand-sewn EJA for gastric cancer between 2013 and 2015 have been retrospectively reviewed. The mean age was 49.9 years; 64 % of patients were male and 36 % were female. The mean body mass index (kg/m²) was 22.4, and the mean American Society of Anesthesiologists (ASA) score was 1.4. Eleven patients had co-morbidities, and six patients had previous abdominal operations. The mean operative time, time for EJA, and blood loss was 136.9 min, 13.25 min, and 166 ml, respectively. The conversion rate was nil. The mean time for the first oral feeding and mean hospital stay was 8.3 and 9.8 days respectively. The postoperative complications were found in 16 % of patients with one case of 30-day mortality because of lobar pneumonia. There were three cases of anastomotic stenosis; however, no leakage was identified both clinically and radiologically. Complete intracorporeal hand-sewn EJA is a safe and feasible technique in the hands of experienced surgeons that can be considered as an alternative cost-effective method when performing LTG.

Totally laparoscopic total gastrectomy for gastric cancer: literature review and comparison of the procedure of esophagojejunostomy

There has been a recent increase in the use of totally laparoscopic total gastrectomy (TLTG) for gastric cancer. However, there is no scientific evidence to determine which esophagojejunostomy (EJS) technique is the best. In addition, both short- and long-term oncological results of TLTG are inconsistent. We reviewed 25 articles about TLTG for gastric cancer in which at least 10 cases were included. We analyzed the short-term results, relationships between EJS techniques and complications, long-term oncological results, and comparative study results of TLTG. TLTG was performed in a total of 1170 patients. The mortality rate was 0.7%, and the short-term results were satisfactory. Regarding EJS techniques and complications, circular staplers (CSs) methods were significantly associated with leakage (4.7% vs. 1.1%, p < 0.001) and stenosis (8.3% vs. 1.8%, p < 0.001) of the EJS as compared with the linear stapler method. The long-term oncological prognosis was acceptable in patients with early gastric cancers and without metastases to lymph nodes. Although TLTG tended to increase surgical time compared with open total gastrectomy and laparoscopy-assisted total gastrectomy, it reduced intraoperative blood loss and was expected to shorten postoperative hospital stay. TLTG is found to be safer and more feasible than open total gastrectomy and laparoscopy-assisted total gastrectomy. At present, there is no evidence to encourage performing TLTG for patients with advanced gastric cancer from the viewpoint of long-term oncological prognosis. Although the current major EJS techniques are CS and linear stapler methods, in this review, CS methods are significantly associated with leakage and stenosis of the EJS.

Is laparoscopic total gastrectomy a safe operation? A review of various anastomotic techniques and their outcomes

Laparoscopic distal gastrectomy is an accepted option for gastric cancer surgery; however, laparoscopic total gastrectomy (LTG) is not widely performed. There is concern about the safety of the operation due to the difficulty of extracorporeal reconstruction through a mini-laparotomy. Efforts have been made to establish an intracorporeal anastomotic technique for esophagojejunostomy. This article reviews the current techniques available for laparoscopic esophagojejunostomy and their surgical outcomes. Several different techniques using either circular or linear staplers have been reported; however, the apparent superiority of any particular method has not been confirmed. The incidence of anastomosis-related complications varied among studies, but different techniques all successfully achieved excellent outcomes. The overall complication rate of LTG was similar to that of open total gastrectomy, suggesting that LTG is a safe and feasible option. However, the feasibility of LTG with D2 lymph node dissection for advanced upper gastric cancer needs to be confirmed in further studies, because most of the patients included in the LTG studies were diagnosed with early stages of disease.

Evaluation of the safety and efficacy of esophagojejunostomy after totally laparoscopic total gastrectomy using a trans-orally inserted anvil: a single-center comparative study

BACKGROUND

Although laparoscopic surgery is frequently performed for the treatment of gastric cancer, laparoscopic total gastrectomy is not widely performed because of its technical difficulty. Since December 2007 we have performed esophagojejunostomy after totally laparoscopic total gastrectomy (TLTG) in more than 110 cases in our institution by using a circular stapler with a trans-orally inserted anvil. We performed a single-center comparative study to evaluate the safety and efficacy of esophagojejunostomy using a trans-orally inserted anvil in patients who underwent TLTG for the treatment of gastric cancer.

METHODS

In the present study, we examined 329 patients with gastric cancer who underwent esophagojejunostomy using a circular stapler after total gastrectomy. Data on the clinicopathological features, operative time, amount of intraoperative blood loss, and incidence of anastomosis-related complications among the surgical groups were obtained by reviewing the medical records, which were then analyzed.

RESULTS

Approximately 67% of the patients were men, and the average patient age was 64.0 years (range 26-93 years). In addition, 166 (50.5%) and 163 (49.5%) patients underwent open and laparoscopic surgery, respectively. Leakage following esophagojejunostomy was noted in 7 (4.2%) of 166 patients who underwent total gastrectomy with open laparotomy, and 0 of 46 patients who underwent laparoscopic-assisted total gastrectomy (LATG). However, only 2 (1.7%) of 117 patients who underwent TLTG using a trans-orally inserted anvil exhibited leakage following esophagojejunostomy. Anastomotic stenosis of the esophagojejunostomy was observed in 5 (3.0%) of 166 patients who underwent total gastrectomy with open laparotomy, 2 (4.3%) of 46 patients who underwent LATG, and 2 (1.7%) of 117 patients who underwent TLTG using a trans-orally inserted anvil.

CONCLUSIONS

We believe that esophagojejunostomy using a trans-orally inserted anvil after TLTG for gastric cancer is a safe and useful surgical procedure.

Feasibility of laparoscopy-assisted total gastrectomy in patients with clinical stage I gastric cancer

BACKGROUND

Laparoscopy-assisted total gastrectomy (LATG) for gastric cancer is not yet widespread because of the technical difficulty of reconstruction. We have performed LATG on 100 patients with clinical stage I gastric cancer. This study investigated the short-term outcomes of LATG.

METHODS

Between September 2001 and September 2012, 100 patients with clinical stage I gastric cancer underwent LATG with D1 plus beta or D2 lymphadenectomy. Roux-en-Y esophagojejunostomy was performed intracorporeally using end-to-side anastomosis with a circular stapler (the purse-string suture method). The primary endpoint was the proportion of postoperative complications during hospitalization.

RESULTS

Mean operation time was 249 min; mean blood loss was 182 ml. There were no conversions to open surgery. According to the Clavien-Dindo classification, there were 8 grade II (8 %) and 10 grade IIIa/b (10 %) complications. There were no treatment-related deaths or grade IV complications. The most frequent complication was anastomotic or stump leakage (6 %), followed by pancreatic fistula (5 %). Reoperations were required in two patients with leakage.

CONCLUSIONS

The short-term outcomes of LATG in our study involving 100 patients were outlined. LATG for gastric cancer patients should be attempted preferably in a clinical trial setting by surgeons with sufficient experience in laparoscopic gastrectomy.

Safety of transorally-inserted anvil for esophagojejunostomy in laparoscopic total gastrectomy

BACKGROUND

To assess the safety of transorally-inserted anvil (TOA) for use during esophagojejunostomy (EJ) reconstruction during laparoscopic total gastrectomy (LTG).

METHODS

Between March 2009 and December 2011, 39 consecutive open total gastrectomies (OTGs) and 36 LTGs using TOA for gastric cancer were comparatively evaluated. We investigated postoperative complications, using the Clavien-Dindo classification. To evaluate the effect of a learning period in using TOA for LTG, we also investigated shifts in the patterns of complications and changes in total operation time over the course of the study.

RESULTS

The patient characteristics at baseline were not different between both groups, except for the extent of lymphadenectomy (P < 0.001) and depth of tumor invasion (P = 0.003). Multivariate analysis revealed that TOA usage elevated the occurrence of infectious complications significantly (OR = 3.32, P = 0.042), but was not associated with EJ-related complications. TOA usage did not need a learning period for the length of time required to complete the operation, or the likelihood of developing an EJ-related or infectious complication.

CONCLUSIONS

TOA use for EJ during LTG is relatively simple and easy enough not to require a learning period for surgeons. This procedure did not elevated the occurrence of EJ-related complications compared to circular stapling in open surgery, but it does require special prevention efforts to avoid infectious complications.

Single incision laparoscopic total gastrectomy and d2 lymph node dissection for gastric cancer using a four-access single port: the first experience

Single incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES) have been developed to reduce the invasiveness of laparoscopic surgery. SILS has been frequently applied in various clinical settings, such as cholecystectomy, colectomy, and sleeve gastrectomy. So far, there have been four reports on single incision laparoscopic distal gastrectomy and one report on single incision laparoscopic total gastrectomy with D1 lymph node dissection for gastric cancer. In this report, we present our single incision laparoscopic total gastrectomy with D2 lymph node dissection technique using a four-hole single port (OctoPort) in a patient with gastric cancer.

Stable purse-string suturing using an anterior esophagotomy for reconstruction with a circular stapler during laparoscopic total gastrectomy

INTRODUCTION

During a laparoscopic total gastrectomy, the combined process of purse-string suture placement and anvil insertion of a circular stapler is one of the most difficult steps in the reconstruction. We have developed a stable and reliable technique in which purse-string suture placement and anvil insertion using anterior esophagotomy precede complete transection of the esophagus.

METHODS

The procedure involves tying the distal esophagus, insufflating the esophagus via a nasogastric tube, anterior wall purse-string suture, anterior esophagotomy, posterior wall purse-string suture, anvil insertion, fastening purse-string suture, and transecting the esophagus. The technique has been employed in nine patients since April 2011.

RESULTS

Eight of the nine gastrectomies were for patients with stage IA early gastric cancer and one was for a patient with medically intractable bleeding from multiple polyps. Three were men and six were women. Average BMI was 25.2 ± 5.3 (range, 16.3-33.9). Mean operation time was 276.2 ± 56.3 min (range, 215.0-395.0 min) and the mean duration for anvil insertion was 29.8 ± 7.0 min (range, 23.0-46.0 min). There were no intraoperative or postoperative anastomosis-related complications or mortality.

CONCLUSION

Our method of anvil insertion of a circular stapler can be a good option for safe and reliable esophagojejunostomy during a laparoscopic total gastrectomy.

Intracorporeal laparoscopic Roux-en-Y gastrojejunostomy after 95% gastrectomy for early gastric cancer in the upper third of the stomach: a report on 21 cases

BACKGROUND

Many reconstructive procedures have been developed in an effort to resolve complications after total gastrectomy (TG). However, anatomical disruption of the esophagogastric junction, especially the low esophageal sphincter, still occurs so that postoperative complications continue to arise. In this study, we developed a procedure for intracorporeal laparoscopic Roux-en-Y gastrojejunostomy (RYGJ) after 95% (near-total) gastrectomy, to reduce postoperative complications in early gastric cancer (EGC) of the upper third of the stomach.

PATIENTS AND METHODS

Laparoscopic RYGJ after 95% gastrectomy was performed on 21 patients with EGC in the upper third of the stomach between May 2011 and April 2012 in Asan Medical Center, Seoul, Korea. The resection line of the stomach was marked using metallic preoperative endoscopic clips and intraoperative laparascopic vessel clips together with a portable abdominal radiograph. Approximately 95% of the stomach was transected using an endoscopic linear stapler, and an antecolic side-to-side gastrojejunal anastomosis was created between the posterior side of the gastric remnant and the antimesenteric side of the jejunal limb, also using an endoscopic linear stapler. The entry hole was first closed in approximate fashion with three sutures, and closure was completed with an endoscopic linear stapler.

RESULTS

Intracorporeal laparoscopic RYGJ after 95% gastrectomy was successfully performed in all patients. No patients required conversion to open surgery or other laparoscopic anastomosis techniques. No postoperative complications occurred. All patients had tumor-free resection margins, and there was no mortality.

CONCLUSIONS

Intracorporeal laparoscopic RYGJ after 95% gastrectomy can be performed easily and safely. We recommend this method over laparoscopic TG or open TG for treatment of EGC in the upper third of the stomach.

Intracorporeal anastomosis in laparoscopic gastric cancer surgery

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.

Long-term outcomes and feasibility with laparoscopy-assisted gastrectomy for gastric cancer

Purpose

Recently, laparoscopy-assisted gastrectomy (LAG) has been widely accepted modality for early gastric cancer in Korea. The indication of LAG may be extended in an experienced institution. In our institution, the first case of laparoscopy-assisted gastrectomy (LAG) for gastric cancer was performed in May 1998. We retrospectively reviewed the long-term oncologic outcomes over 12 years to clarify the feasibility of LAG for gastric cancer.

Materials and Methods

The authors retrospectively analyzed 753 patients who underwent LAG for gastric cancer, from May 1998 to August 2010. We reviewed clinicopathological features, postoperative outcomes, mortality and morbidity, recurrence, and survival of LAG for gastric cancer.

Results

During the time period, 3,039 operations for gastric cancer were performed. Among them, 753 cases were done by LAG (24.8%). There were 69 cases of total gastrectomy, 682 subtotal gastrectomies, and 2 proximal gastrectomies. According to TNM stage, 8 patients were in stage 0, 619 in stage I, 88 in stage II, and 38 in stage III. The operation-related complications occurred in 77 cases (10.2%). Median follow-up period was 56.2 months (range 0.7~165.6 months). Twenty-five patients (3.3%) developed recurrence, during the follow-up period. The overall 5-year and disease free survival rates were 97.1% and 96.3%, respectively.

Conclusions

The number of postoperative complications and survival rates of our series were comparable to the results from that of other reports. The authors consider LAG to be a feasible alternative for the treatment of early gastric cancer. However, rationale for laparoscopic surgery in advanced gastric cancer has yet to be determined.
