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

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.

A comparative study of laparoscopic near-total and total gastrectomy for patient nutritional status and quality of life using a propensity score matching analysis

BACKGROUND

Previous studies of LNTG had small sample sizes and short follow-up periods and did not evaluate quality of life after LNTG. We aimed to compare surgical, oncological, nutritional outcomes, and quality of life of patients after laparoscopic near-total and total gastrectomy (LNTG and LTG, respectively).

METHODS

We retrospectively collected and analyzed data of 167 and 294 patients who underwent LNTG and LTG, respectively, for treatment of upper or middle third gastric cancer between January 2008 and December 2018. After propensity score matching, the surgical, oncological, and nutritional outcomes of 324 patients were analyzed. Moreover, we measured quality of life after surgery using a postgastrectomy syndrome scale.

RESULTS

The operation time and the length of hospital stay was significantly shorter in the LNTG group than in the LTG group. In addition, patients with anastomotic complications were fewer in the LNTG group. No significant difference was found in the 5-year overall survival rate between the two groups. However, patients in the LNTG group had a significantly smaller body weight loss after 3 months postoperatively. Furthermore, patients in the LNTG group had significantly healthier albumin and cholesterol than those in the LTG group. The mean scores on the postgastrectomy symptom scale at 3, 6, and 12 months postoperatively were higher in the LNTG group than in the LTG group.

CONCLUSION

LNTG is a surgically safe and oncologically favorable method compared with LTG. Furthermore, patients who underwent LNTG had improved nutritional status and quality of life than those who underwent LTG.

Early Surgical and Long-term Oncological Outcomes of Totally Laparoscopic Near-total Gastrectomy in >150 Cases

BACKGROUND

This study aimed to examine the early surgical outcomes and long-term oncological safety of totally laparoscopic near-total gastrectomy for the treatment of upper-third early gastric cancer.

MATERIALS AND METHODS

We retrospectively collected and analyzed the data of 167 consecutive patients who underwent totally laparoscopic near-total gastrectomy for upper-third early gastric cancer between January 2008 and May 2018. Data on clinical characteristics and surgical outcomes, including operation time, length of postoperative hospital stay, pathologic findings, and postoperative complications, were obtained. We also analyzed recurrence-free and overall survival rates to evaluate the oncological outcomes.

RESULTS

The mean operation time was 149.44±37.59 minutes; none of the patients required conversion to laparotomy during surgery. The average postoperative hospital stay was 7.57±5.69 days. On final pathologic analysis, the mean proximal resection margin was 1.97±1.68 cm. No patients had an involved proximal resection margin. Twenty-seven patients (16.17%) had postoperative complications; of them, 6 patients (3.59%) had Clavien-Dindo classification grade 3 or higher complications, all within 1 month. The median follow-up duration was 54.35 months. The 3- and 5-year recurrence-free survival rates were 98.3% and 97.1%, respectively. The overall survival rate was 97.1% at both 3 and 5 years.

CONCLUSIONS

Our study shows that totally laparoscopic near-total gastrectomy is a safe and feasible procedure for treating the upper-third early gastric cancer. Further, in the current study, the procedure demonstrated a favorable oncological outcome for a relatively long follow-up period and large sample size.

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.

Diaphragmatic Hernia After Totally Laparoscopic Total Gastrectomy for Gastric Cancer

This study aimed to investigate the occurrence of diaphragmatic hernia (DH) after totally laparoscopic total gastrectomy (TLTG) for gastric cancer. We reviewed retrospectively collected data from 490 consecutive patients who underwent TLTG (functional method, 365; overlap method, 125) for upper body gastric cancer, between January 2011 and May 2017, performed by a single surgeon. The median follow-up period was 40.6 months. Of 490 patients, 8 (1.63%) developed DH at a mean interval after TLTG of 7.3 (range, 3.4 to 12.8) months. All 8 patients were from the functional group, and presented with abdominal pain or vomiting. They were managed with emergency surgery (5 laparoscopic hernia reduction, 3 open hernia reduction). The grade of complication according to Clavien-Dindo classification (CDC) was CDC-III in 7 cases and CDC-IV in 1 case. There was no death associated with DH complications. None of the patients in the overlap group developed DH. The incidence of DH after TLTG is negligible in the overlap method. Therefore, the overlap method may be a safe reconstruction technique that can reduce the occurrence of DC after TLTG for gastric cancer.

Use of a clinical pathway in laparoscopic gastrectomy for gastric cancer

AIM: To evaluate the implementation of a clinical pathway and identify clinical factors affecting the clinical pathway for laparoscopic gastrectomy.

METHODS: A standardized clinical pathway for gastric cancer (GC) patients was developed in 2001 by the GC surgery team at the Asan Medical Center. We reviewed the collected data of 4800 consecutive patients treated using the clinical pathway following laparoscopic gastrectomy with lymph node dissection for GC involving intracorporeal and extracorporeal anastomosis. The patients were treated between August 2004 and October 2013 in a single institution. To evaluate the rate of completion and risk factors affecting dropout from the clinical pathway, we used a multivariate logistic regression analysis.

RESULTS: The overall completion rate of the clinical pathway for laparoscopic gastrectomy was 84.1% (n = 4038). In the comparison between groups of intracorporeal anastomosis and extracorporeal anastomosis patients, the completion rates were 83.88% (n = 1740) and 84.36% (n = 2071), respectively, showing no statistically significant difference. The main reasons for dropping out were postoperative complications (n = 463, 9.7%) and the need for patient observation (n = 299, 6.2%). Among the discharged patients treated using the clinical pathway, the number of patients who were readmitted within 30 d due to postoperative complications was 54 (1.1%). In a multivariate analysis, the intraoperative events (OR = 2.558) were the most predictable risk factors for dropping out of the clinical pathway. Additionally, being male (OR = 1.459), advanced age (OR = 1.727), total gastrectomy (OR = 2.444), combined operation (OR = 1.731), and ASA score (OR = 1.889) were significant risk factors affecting the dropout rate from the clinical pathway.

CONCLUSION: Laparoscopic gastrectomy appears to be a good indication for the application of a clinical pathway. For successful application, patients with risk factors should be managed carefully.

Intracorporeal esophagojejunostomy using the double stapling technique after laparoscopic total gastrectomy: A retrospective case-series study

AIM: To introduce a simple and safe anvil insertion technique to esophagus during laparoscopic total gastrectomy (LTG).

METHODS: Between July 2010 and December 2012, 58 consecutive patients with early gastric cancer underwent LTG were enrolled. We performed a simple and safe Roux-en-Y esophagojejunostomy using the double stapling technique to all patients. Then patients’ characteristics, perioperative outcome and histopathologic data were analyzed retrospectively.

RESULTS: The mean age and body mass index were 59.3 ± 9.7 years and 22.7 ± 2.6 kg/m². The mean operation, reconstruction and anvil insertion times (from gastric incision to linear stapling) were 251.8 ± 57.0, 43.1 ± 2.8 and 4.2 ± 1.9 min, respectively. Intraoperative blood loss was 204.6 ± 156.3 mL and there was no open conversion. The postoperative complications were in 8 cases (delayed gastric emptying in 4 cases, pulmonary complication in 2 cases, pancreatitis in 1 case, anastomotic stricture in 1 case). Anastomotic stricture occurred after discharge and was recovered by endoscopic intervention. The patients were discharged at a mean of 9.6 ± 2.0 d after surgery. Neither leakage nor bleeding from the esophagojejunostomy occurred postoperatively. The mean proximal margin of specimen was 2.7 ± 2.8 cm

CONCLUSION: Roux-en Y esophagojejunostomy using the double stapling technique is simple and rapid, and it may offer a solid, alternative reconstruction method for LTG or proximal gastrectomy.

Totally laparoscopic 95% gastrectomy for cancer: technical considerations

INTRODUCTION

Total gastrectomy is the standard treatment for tumours arising in the proximal stomach and for diffuse cancer according to the Lauren classification. Laparoscopic approach is progressively accepted and provides encouraging results. In order to reduce complications associated to the esophago-jejunal anastomosis, the concept of the 95 % open gastrectomy was developed in Japan, in the early 1980s. This procedure provides the spearing of a small remnant gastric stump of 2 cm and allows performing a gastro-jejunal anastomosis. Unlike the 7/8 gastrectomy, the 95 % gastrectomy allows the complete resection of the gastric fundus and an optimized pericardial lymph node dissection (group 1 and 2). We herein describe, step-by-step, our technique of full laparoscopic 95 % gastrectomy (G95 %), with D2 lymphadenectomy, including complete lymphadenectomy of the cardial nodes.

DISCUSSION

When it is possible to respect the oncologic criteria regarding proximal resection margin, 95 % gastrectomy would offer best short-term results, such as lower anastomotic leak rate and a better quality of life, limiting the effect of disruption of the eso-gastric junction.

CONCLUSION

In selected patients, laparoscopic G95 % is feasible and safe; it could be performed without any additional technical difficulties. Controlled clinical trials are necessary to confirm the encouraging results of the cases series, recently reported in literature.

Step-by-step esophagojejunal anastomosis after intra-corporeal total gastrectomy for laparoscopic gastric cancer treatment: technique of "reverse anvil"

Background

The laparoscopic gastrectomy is a relatively new procedure due mainly to the difficulties related to lymphadenectomy and reconstruction. Until the moment, technique or device to perform the esophagojejunal anastomosis by laparoscopy is still a challenge. So, a safe, cheap and quickly performing technique is desirable to be developed.

Aim

To present technique proposed by the authors with its technical details on reconstruction with "reverse anvil".

Method

After total gastrectomy completed intra-corporeally, the reconstruction starts with the preparation of the intra-abdominal esophagus cross-section next to the esophagogastric transition of 50%. A graduated device is prepared using Levine gastric tubes (nº. 14 and 10), 3 cm length, connected to the anvil of the circular stapler (nº. 25) with a wire thread (2-0 or 3-0) of 10 cm, which is connected to end of this device. The whole device is introduced in reverse esophagus. The esophagus is amputated and the wire is pulled after previous transfixation in the distal esophagus and the anvil positioned. The jejunal loop is sectioned 20-30 cm from duodenojejunal angle, and the anvil put in the jejunal loop and connect previously in the esophagus. Linear stapler (blue 60 mm) is used to close the opening of the jejunal loop.

Conclusion

The "reverse anvil" technique used by the authors facilitated the transit reestablishment after total gastrectomy, contributing to obviate reconstruction problems after total gastrectomy.
