Table 2.
Comparison of phases in laparoscopic sleeve gastrectomy and the laparoscopic part of IL-Esophagectomy
| Esophagectomy phases | Sleeve gastrectomy phases | Similarities | Differences | Challenges |
|---|---|---|---|---|
| Port placement | Port placement | Visually indifferent, an occurrence at the beginning of the video | Position of optical port/instrument manufacturer | |
| Liver retraction | Liver retraction | Visually indifferent, an occurrence at the beginning of the video | Instrument manufacturer | |
| N/A | Liver Biopsy | N/A | N/A | |
| Dissection of gastrohepatic Ligament | N/A | N/A | N/A | Few visual similarities between gastrohepatic and gastrocolic ligament |
| Clipping + division of left gastric artery | N/A | N/A | N/A | Mostly no alternative Clipping actions in Sleeve Gastrectomy |
| Hiatal dissection | N/A | N/A | N/A | A very short segment of dissection of the left Crus within phase “Gastrocolic Ligament Dissection” in Sleeve Gastrectomy |
| Dissection of gastrocolic ligaMent | Dissection gastrocolic ligament | Same anatomic location and visual surroundings, similar durations | Dissection closer to the gastric conduit in Esophagectomy / different instruments: Harmonic vs | |
| Stapling | Stapling stomach | Same anatomic location and visual surroundings, similar durations, number of stapling rows | Stapling side of the stomach, stapling angle, | Different stapling side of the stomach and stapling angle |
| N/A | Bagging specimen | N/A | N/A | No bagging in esophagectomy, hence no results shown |
| Mediastinal dissection | N/A | N/A | N/A | Not existent in Sleeve gastrectomy |
| ICG check | N/A | N/A | N/A | No fluorescent inspection in Sleeve gastrectomy by visually very distinct phase |
| Final inspection | Final inspection | No active instruments/same anatomic operative field | A different angle of inspection due to different port position | Occurs at the end of Sleeve gastrectomy vs. very intermittent during esophagectomy |
