β-Shaped intracorporeal Roux-en-Y reconstruction after totally laparoscopic distal gastrectomy

Short- and long-term outcomes of Roux-en-Y and Billroth II with Braun reconstruction in total laparoscopic distal gastrectomy: a retrospective analysis

BACKGROUND

The controversy surrounding Roux-en-Y (R-Y) and Billroth II with Braun (BII + B) reconstruction as an anti-bile reflux procedure after distal gastrectomy has persisted. Recent studies have demonstrated their efficacy, but the long-term outcomes and postoperative quality of life (QoL) among patients have yet to be evaluated. Therefore, we compared the short-term and long-term outcomes of the two procedures as well as QoL.

METHODS

The clinical data of 151 patients who underwent total laparoscopic distal gastrectomy (TLDG) at the Gastrointestinal Surgery Department of the Second Hospital of Fujian Medical University from January 2016 to December 2019 were retrospectively analyzed. Of these, 57 cases with Roux-en-Y procedure (R-Y group) and 94 cases with Billroth II with Braun procedure were included (BII + B group). Operative and postoperative conditions, early and late complications, endoscopic outcomes at year 1 and year 3 after surgery, nutritional indicators, and quality of life scores at year 3 postoperatively were compared between the two groups.

RESULTS

The R-Y group recorded a significantly longer operative time (194.65 ± 21.52 vs. 183.88 ± 18.02 min) and anastomotic time (36.96 ± 2.43 vs. 27.97 ± 3.74 min) compared to the BII + B group (p < 0.05). However, no other significant differences were observed in terms of perioperative variables, including blood loss (p > 0.05). Both groups showed comparable rates of early and late complications. Endoscopic findings indicated similar food residuals at years 1 and 3 post-surgery for both groups. The R-Y group had a lower occurrence of residual gastritis and bile reflux at year 1 and year 3 after surgery, with a statistically significant difference (p < 0.001). Reflux esophagitis was not significantly different between the R-Y and BII + B groups in year 1 after surgery (p = 0.820), but the R-Y group had a lower incidence than the BII + B group in year 3 after surgery (p = 0.023). Nutritional outcomes at 3 years after surgery did not differ significantly between the two groups (p > 0.05). Quality of life scores measured by the QLQ-C30 scale were not significantly different between the two groups. However, on the QLQ-STO22 scale, the reflux score was significantly lower in the R-Y group than in the BII + B group (0 [0, 0] vs. 5.56 [0, 11.11]) (p = 0.003). The rest of the scores were not significantly different (p > 0.05).

CONCLUSION

Both R-Y and B II + B reconstructions are equally safe and efficient for TLDG. Nevertheless, the R-Y reconstruction reduces the incidence of residual gastritis, bile reflux, and reflux esophagitis, as well as postoperative reflux symptoms, and provides a better quality of life for patients. R-Y reconstruction is superior to BII + B reconstruction for TLDG.

Simplified Roux-en-Y reconstruction after laparoscopic radical distal gastrectomy for gastric cancer

Background

Although there were a variety of strategies for the alimentary tract reconstruction of patients with gastric cancer who underwent laparoscopic radical distal gastrectomy, it remains controversial regarding which procedure is optimal. We developed a simple technique for Roux-en-Y reconstruction during laparoscopic surgery and evaluated its technical feasibility and safety.

Methods

Seventy-one cases of modified Roux-en-Y reconstructions after laparoscopic radical distal gastrectomy were consecutively performed in our hospital, from November 2020 to March 2022. A retrospective review of medical data was conducted. Intraoperative and postoperative outcomes, including operation time and incidence of postoperative complications, were collected and analyzed.

Results

All procedures of laparoscopic distal gastrectomy with D2 lymph node dissection were successfully completed without any intraoperative complication. The mean number of retrieved lymph node was 38.8 ± 10.6. Mean operative time was 223.5 ± 42.4 min, whereas intraoperative blood loss was 102.2 ± 96.3 ml. No postoperative mortality was recorded. Six patients (8.5%) experienced postoperative complications and were managed conservatively. In addition, only two patients (2.8%) required rehospitalization during a median short-term follow-up period of 6 months.

Conclusions

The modified method is a simple and safe approach for laparoscopic radical distal gastrectomy.

Intracorporeal gastrojejunostomy in Roux-en-Y reconstruction with its efferent loop located on the patient's left side following totally laparoscopic distal gastrectomy: A case report

The drawback of intracorporeal gastrojejunostomy using only endoscopic linear staplers in antecolic Roux-en-Y (R-Y) reconstruction with its efferent loop located on the patient's left side following totally laparoscopic distal gastrectomy (TLDG) is the occurrence of anastomotic failure, even though this reconstruction system is assumed to prevent intraoperative and postoperative twisting of the gastrojejunostomy and lifted jejunum. This case report presents two patients with gastric cancer who underwent intracorporeal gastrojejunostomy consisting of linear stapling and hand suturing in antecolic R-Y reconstruction with its efferent loop located on the patient's left side following TLDG to prevent anastomotic failure of the gastrojejunostomy. After the sacrificed jejunum was created, linear stapling of the greater curvature of the remnant stomach and the lifted jejunum without dividing the jejunum was performed. After removing the sacrificed jejunum and creating a good view of the posterior side of the stapler entry hole, the stapler entry hole was closed from the posterior side to the anterior side, using a single-layer full-thickness and serosubmucosal hand suturing technique with knotted sutures and a knotless barbed suture. No anastomotic failure of the gastrojejunostomy occurred in either patient. Intracorporeal gastrojejunostomy consisting of linear stapling and hand suturing could be an option for gastrojejunostomy in antecolic R-Y reconstruction with its efferent loop located on the patient's left side following TLDG because it can aid in the prevention of anastomotic failure.

Easy fixation effects the prevention of Peterson’s hernia and Roux stasis syndrome

BACKGROUND

Laparoscopic distal gastrectomy (LDG) for gastric cancer has been progressed and popular in Japan, since it was first described in 1994. Several reconstruction methods can be adopted according to remnant stomach size, and balance of pros and cons. Roux-en-Y (R-Y) reconstruction is a one of standard options after LDG. Its complications include Petersen’s hernia and Roux stasis syndrome. Here we report our ingenious attempt, fixation of Roux limb and duodenal stump, for decreasing the development of Petersen’s hernia and Roux stasis syndrome.

AIM

To develop a method to decrease the development of Petersen’s hernia and Roux stasis syndrome.

METHODS

We performed ante-colic R-Y reconstruction after LDG. After R-Y reconstruction, we fixed Roux limb onto the duodenal stump in a smooth radian. Via this small improvement in Roux limb, Roux limb was placed to the right of the ligament of Treitz. This not only changed the anatomy of the Petersen’s defect, but it also kept a fluent direction of gastrointestinal anastomosis and avoided a cross-angle after jejunojejunostomy. 31 patients with gastric cancer was performed this technique after R-Y reconstruction. Clinical parameters including clinicopathologic characteristics, perioperative outcomes, postoperative complication and follow-up data were evaluated.

RESULTS

The operative time was (308.0 ± 84.6 min). This improvement method took about 10 min. Two (6.5%) patients experienced pneumonia and pancreatitis, respectively. No patient required reoperation or readmission. All patients were followed up for at least 3 year, and none of the patients developed postoperative complications related to internal hernia or Roux stasis syndrome.

CONCLUSION

This 10 min technique is a very effective method to decrease the development of Petersen’s hernia and Roux stasis syndrome in patients who undergo LDG.

Surgical Outcomes and Follow-Up Results of 100 Cases of Laparoscopic Total Gastrectomy Using the Overlap Method with Stapled Closure

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.

Intracorporeal classic circular-stapled gastrojejunostomy and jejunojejunostomy during laparoscopic distal gastrectomy: A simple, safe "intraluminal poke technique" for anvil placement

BACKGROUND

Totally laparoscopic distal gastrectomy is being increasingly performed. However, an optimal procedure to achieve intracorporeal gastrojejunostomy and jejunojejunostomy for Roux-en-Y reconstruction after laparoscopic distal gastrectomy remains to be established. Compared with the simple and preferable circular-stapled Roux-en-Y reconstruction in open gastrectomy, application of intracorporeal circular-stapled gastrojejunostomy and jejunojejunostomy of Roux-en-Y reconstruction during laparoscopic distal gastrectomy have been limited (no report of intracorporeal circular-stapled jejunojejunostomy) because of the difficulties of intracorporeal purse-string suture and anvil placement. To address these problems, a simple and safe intraluminal poke technique of universal surgical concept and procedure was introduced and evaluated.

METHODS

Between March 2018 and August 2018, 24 consecutive patients with gastric cancer underwent totally laparoscopic distal gastrectomy in our hospital. Roux-en-Y reconstruction of intracorporeal circular-stapled gastrojejunostomy and jejunojejunostomy with the intraluminal poke technique was performed in all patients. Demographic and clinicopathologic characteristics, perioperative details and postoperative outcomes were analyzed.

RESULTS

The mean operative time was 203.6±26.2min, both proximal and distal tumor-free margins were achieved in all patients. The time for anvil placement at stomach and intestine was 5.9±1.3min and 3.9±0.7min, respectively. Intracorporeal gastrojejunostomy and jejunojejunostomy were successively completed following anvil placement with no any anastomosis-related sutures. There were 5 postoperative complications. Morbidities included pancreas fistula (n=1), stasis (n=2), atelectasis (n=1), pneumonia (n=1). These all patients recovered after conservative treatment. No postoperative anastomosis-related complications, such as anastomotic bleeding and leakage, or stenosis occurred during the median follow-up of 6.5 months.

CONCLUSION

The initial results suggest that the technique allowing easy and common anvil placement at stomach and intestine may be a simple, safe, preferable and time-saving procedure to accomplish intracorporeal circular-stapled gastrojejunostomy and jejunojejunostomy of Roux-en-Y reconstruction in totally laparoscopic distal gastrectomy as open surgery.

Long-term functional outcomes of Roux-en-Y versus Billroth I reconstructions after laparoscopic distal gastrectomy for gastric cancer: a propensity-score matching analysis

BACKGROUND

Only a few reports discuss long-term functional outcomes and changes observed in patients over several years following a distal gastrectomy. We investigated long-term functional outcomes and changes after laparoscopic distal gastrectomy based on the analysis of postoperative conditions and endoscopic findings observed in patients.

METHODS

The study group comprised 159 patients who underwent Roux-en-Y reconstruction following laparoscopic distal gastrectomy (R-Y group) between December 2008 and November 2012 and 78 patients who underwent Billroth I reconstruction (B-I group) between January 2002 and November 2012. To minimize bias between the two groups, propensity scores were calculated using a logistic regression model. The groups were compared with respect to postoperative conditions and endoscopic findings at 1, 3, and 5 years postoperatively.

RESULTS

The B-I group demonstrated more frequent heartburn than the R-Y group at 3 and 5 years postoperatively. No significant differences were found in terms of loss of body weight and food intake. Endoscopic findings showed significantly lesser residual food and remnant gastritis in the R-Y group at each annual postoperative follow-up. The incidence of bile reflux and reflux esophagitis in the B-I group gradually increased over the years and showed a significant difference at the culmination of the 5-year postoperative follow-up, compared to the R-Y group.

CONCLUSIONS

Roux-en-Y reconstruction was superior to Billroth I reconstruction in terms of frequency of occurrence of residual food, bile reflux, remnant gastritis, and reflux esophagitis in the long term. Differences between the two methods became more evident as the follow-up period lengthened.

Feasibility of a Clinical Pathway With Early Oral Intake and Discharge for Laparoscopic Gastrectomy

BACKGROUND AND AIMS

Although some studies have reported the safety of early oral intake after gastrectomy, it still remains controversial. This study focused on the feasibility of a clinical pathway with early oral intake and discharge setting for exclusively laparoscopic distal gastrectomy.

MATERIALS AND METHODS

A clinical pathway was applied to 403 patients until December 2014. In the protocol, patients are allowed to take a sip of water and a soft diet on the first and second days after the operation, respectively, and the discharge day is set as the fifth to seventh day after the operation. Clinicopathological variables were prospectively collected, and risk factors for discharge variances were analyzed.

RESULTS

The completion rate of the clinical pathway was 76.9%. There were five re-admissions (1.2%). The overall morbidity rate was 18% ( n = 72), and major complications (Clavien-Dindo IIIa or greater) occurred in 13 patients (3%). Complications were the causes for discharge variances in 68 cases (73%), while the attending surgeons' judgment was the cause in 25 cases (27%). On multivariate analysis, age (odds ratio = 2.23, 95% confidence interval = 1.38-3.60, p = 0.001) and operative time (odds ratio = 2.38, 95% confidence interval = 1.45-3.98, p = 0.001) were independent risk factors for discharge variances.

CONCLUSION

A high completion rate of a clinical pathway with early oral intake and discharge setting for laparoscopic distal gastrectomy was achievable with an acceptably low re-admission rate. Laparoscopic distal gastrectomy is recommended as a first step for a clinical pathway with an early oral intake and discharge protocol.

The Advances of Laparoscopic Gastrectomy for Gastric Cancer

Laparoscopic gastrectomy is evolving. With the increasing expertise and experience of oncologic surgeons in the minimally invasive surgery for gastric cancer, the indication for laparoscopic gastrectomy is expanding to advanced cases. Many studies have demonstrated the benefits of minimally invasive surgery, including reduced risk of surgery-related injury, reduced blood loss, less pain, and earlier recovery. In order to establish concrete evidence for the suitability of minimal invasive surgery for gastric cancer, many multicenter RCTs, comparing the short- and long-term outcomes of laparoscopic versus open surgery, are in progress. Advances in laparoscopic gastrectomy are moving toward increasingly minimally invasive approaches that enable the improvement of the quality of life of patients, without compromising on oncologic safety.

Stapling an extracorporeal Billroth-I anastomosis by the complete double stapling technique after laparoscopy-assisted distal gastrectomy

INTRODUCTION

Laparoscopy-assisted distal gastrectomy is one of the major treatments for early stage gastric cancer, particularly in the East Asia. In this method, extracorporeal anastomosis is performed via a small laparotomy wound, but excessive tissue traction may be encountered during the anastomotic procedure. Therefore, we developed an original procedure for extracorporeal Billroth-I reconstruction: end-to-end stapling gastroduodenostomy with complete double stapling technique. This procedure aims to reduce the problems related to maneuvers through a small laparotomy.

METHODS

An end-to-end anastomosis is constructed on the transection line using a circular stapler inserted from the distal end of the greater curvature of the remnant stomach. Short-term outcomes were reviewed in 218 consecutive patients who underwent complete double stapling technique reconstruction after laparoscopy-assisted distal gastrectomy between 2002 and 2012. Findings from GI endoscopy were reviewed in 110 patients.

RESULTS

The mean operative time was 216 min, and mean blood loss was 163 mL. There was no conversion to the open surgery and no operative death. Eight patients (3.6%) had anastomosis-related postoperative complications. In follow-up endoscopic examinations 1 year after surgery, grade 3 or higher residual food was seen in 17.2% of patients. Gastritis extending to the entire remnant stomach was observed in 8.2% of patients, and grade 3 gastritis was seen in 2.7%. Los Angeles classification grade A or higher reflux esophagitis was found in 10.9%.

CONCLUSIONS

Billroth-I reconstruction by the complete double stapling technique is a safe and feasible procedure. This method provides satisfactory short-term outcomes, including the incidence of reflex remnant gastritis and esophagitis.

Spleen preservation versus splenectomy in laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer: A comparison of short-term outcomes

INTRODUCTION

Splenic hilar lymph node dissection via a splenectomy for advanced proximal gastric cancer remains controversial. Recently, a laparoscopic spleen-preserving hilar lymph node dissection procedure was described in several publications. To assess the feasibility and safety of spleen-preserving laparoscopic total gastrectomy with D2 lymphadenectomy (LTG-D2), the present retrospective study compared the short-term surgical outcomes between spleen preservation and splenectomy during laparoscopic D2 total gastrectomy (LTG-D2S).

METHOD

This study included 59 patients who underwent LTG-D2 and 19 patients who underwent LTG-D2S.

RESULTS

The mean operation time did not significantly differ between the LTG-D2 and LTG-D2S groups (339.4 ± 56.8 vs 356.8 ± 46.0 min). The mean blood loss tended to be smaller in the LTG-D2 group than in the LTG-D2S group (105.9 ± 89.7 vs 210.0 ± 149.5 mL). The mean number of retrieved lymph nodes did not significantly differ between the LTG-D2 and LTG-D2S groups (39.9 ± 17.0 vs 40.6 ± 14.9), and the mean number of retrieved lymph nodes at the splenic hilum also did not significantly differ between the LTG-D2 and LTG-D2S groups (1.3 ± 1.7 vs 2.4 ± 2.6). Mild pancreatic fistula occurred in three cases (5%) in the LTG-D2 group and in three cases (15.8%) in the LTG-D2S group.

CONCLUSION

A LTG-D2 is feasible in terms of the short-term outcomes. However, the indications for this complicated procedure should be considered carefully.

Development of a non-blurring, dual-imaging tissue marker for gastrointestinal tumor localization

BACKGROUND

Knowing the exact location of gastrointestinal tumors both preoperatively and intraoperatively is essential for planning and performing laparoscopic surgery. Different techniques have been introduced to ascertain tumor locations during surgery, but none of these are fully satisfactory at establishing the minimum margins for organ resection while retaining curability. A new, non-blurring tissue marker, detectable by both X-ray computed tomography (CT) and near-infrared (NIR) fluorescence laparoscopy, has been developed, and we here examine its utility using an animal model.

METHODS

Liposomes, comprised phospholipids and an NIR fluorescent dye (an indocyanine green derivative), and emulsions, consisting of phospholipids and oily radiographic contrast medium, were combined with polyglycerol-polyricinoleate to form giant cluster-like vesicles. This vesicular dispersion (300 μl) was administered into the porcine gastric submucosa using a gastroendoscope, and the detectability of the marker was examined using X-ray CT and NIR fluorescence laparoscopy.

RESULTS

One hour after the administration of the vesicular dispersion, X-ray CT identified four individual injection sites, each at a 1-cm radius of a metal hemostasis clip. NIR fluorescence laparoscopy detected individual fluorescent spots 18 hours after the administration of the vesicular dispersion.

CONCLUSION

We anticipate that this newly developed tissue marker will contribute to the preoperative simulation of laparoscopic gastrointestinal cancer surgery and its intraoperative navigation.
