Totally laparoscopic total gastrectomy and the challenge of esophagojejunostomy

Evaluating the Role of Robotic Surgery Gastric Cancer Treatment: A Comprehensive Review by the Robotic Global Surgical Society (TROGSS) and European Federation International Society for Digestive Surgery (EFISDS) Joint Working Group

INTRODUCTION

Robot-assisted minimally invasive gastrectomy (RAMIG) represents a significant advancement in the surgical management of gastric cancer, offering superior dexterity, enhanced visualization, and improved ergonomics compared to laparoscopic gastrectomy (LG). This review systematically evaluates the current evidence on perioperative outcomes, oncological efficacy, learning curves, and economic considerations, providing insights into RAMIG's potential role in modern gastric cancer surgery.

METHODS

A thorough analysis of retrospective, prospective, and meta-analytic studies was conducted to compare RAMIG with LG. Key outcomes, including operative time, intraoperative blood loss, lymph node retrieval, postoperative complications, learning curve duration, and cost-effectiveness, were assessed. Emphasis was placed on both short-term and long-term oncological outcomes to determine the clinical value of RAMIG.

RESULTS

Evidence indicates that RAMIG is associated with reduced intraoperative blood loss, lower morbidity rates, and a shorter learning curve, with proficiency achieved after 11-25 cases compared to 40-60 cases for LG. The robotic platform's articulated instruments and enhanced three-dimensional visualization enable more precise lymphadenectomy, particularly in complex anatomical regions. Despite these advantages, operative time remains longer, and costs remain higher due to system acquisition, maintenance, and consumable expenses. However, emerging data suggest a gradual narrowing of cost disparities. While short-term outcomes are favorable, further high-quality, multicenter studies are needed to validate long-term oncological efficacy and survival outcomes.

CONCLUSION

RAMIG offers significant technical and clinical advantages over conventional LG, particularly in terms of precision and learning efficiency. However, the long-term oncological benefits and economic feasibility require further validation. Future research should focus on cost optimization, advanced technological integration such as near-infrared fluorescence and artificial intelligence, and multicenter trials to solidify RAMIG's role as a standard approach for gastric cancer surgery.

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.

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 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.

Totally laparoscopic total gastrectomy using endoscopic linear stapler: early experiences at one institute

BACKGROUND

Totally laparoscopic total gastrectomy (TLTG) for gastric cancer is still uncommon because of the technical difficulty of performing the esophagojejunostomy laparoscopically. We have developed a secure technique for intracorporeal esophagojejunostomy and successfully performed the TLTG method using an endoscopic linear stapler. Our experiences with this method are reported here.

SUBJECTS AND METHODS

Between July 2009 and May 2010, 124 patients with gastric cancer underwent TLTG using endoscopic linear staplers in one institution. The clinicopathological data and surgical outcomes of the first 70 cases and the subsequent 54 cases were reviewed retrospectively and compared because technical improvements were instituted after the 70th case.

RESULTS

The two groups differed significantly in terms of mean operation time (189.0 versus 148.3 minutes, P<.001), overall postoperative complication rate (37.1% versus 13.0%, P=.003), severe postoperative complication rate (15.7% versus 3.7%, P=.030), and intraoperative event rate (12.9% versus 1.9%, P=.042).

CONCLUSIONS

The early period of performing TLTG using an endoscopic linear stapler was associated with a high morbidity rate. This improved significantly when key technical changes were introduced. However, surgeons who are inexperienced in laparoscopic gastrectomy should be careful when performing TLTG because it involves many complex processes. The account in this report of our experiences with TLTG may help surgeons to master this method faster and more safely.
