Purpose: We retrospectively examined the short‐term outcomes of robot‐assisted minimally invasive esophagectomy compared to open esophagectomy and thoracoscopic esophagectomy.
Patients and Methods: Between November 2018 and August 2021, we analyzed 120 patients who underwent subtotal esophagectomy for esophageal cancer. We divided patients into three groups consisting of a thoracotomy group (29 patients), a thoracoscopic group （48 patients）, and a robot‐assisted group (43 patients). The groups were compared for short‐term outcomes.
Results: Regarding postoperative respiratory complications, atelectasis was significantly lower in the robot‐assisted group than in the thoracotomy and thoracoscopic groups (p＝0.041). Pleural effusion was significantly lower in the robot‐assisted group than in the thoracoscopic group (p＝0.028); however, the incidence of pneumonia was not significantly different among the three groups. Recurrent laryngeal nerve paralysis was lower in the thoracoscopic group and the robot‐assisted group than in the thoracotomy group for patients with Clavien‐Dindo classification (CD) ≥ 1. No case of recurrent laryngeal nerve paralysis with CD ≥ 2 was observed in the robot‐assisted group, which was significantly less than that in the thoracotomy group (p＝0.004).
Conclusion: Robot‐assisted minimally invasive esophagectomy may reduce recurrent laryngeal nerve palsy and respiratory complications. Further case accumulation is needed.

Isolated hypoganglionosis (IH) is a disease with a poor prognosis whose main condition is functional intestinal obstruction in the widespread intestinal tract from birth. Clinical practice guidelines suggest upper jejunostomy as a gastrointestinal decompression treatment. Consensus is being reached on the treatment method；however, there are no specific proposals and due to their rarity, initial treatments often vary depending on the institution and the case. In this study, we performed upper jejunal stoma, tube jejunostomy, and lower intestinal stoma construction in the initial surgical treatment and nutrition therapy from the neonatal period for IH five cases, and established enteral nutrition and appropriate nutrition. By controlling enteral inflammation by decompression, we were able to shift to home medical care around a year of age without developing severe complications, such as enterocolitis, in four out of five cases. It was suggested that in the initial treatment of IH, it may be useful to create an appropriate decompression route and enteral feeding route even if there are multiple ostomies.
