Technical details for a robot-assisted hand-sewn esophago-gastric anastomosis during minimally invasive Ivor Lewis esophagectomy.

BACKGROUND: Minimally invasive Ivor Lewis esophagectomy (MIILE) provides better outcomes than open techniques, particularly in terms of post-operative recovery and pulmonary complications. However, in addition to requiring advanced technical skills, thoracoscopic access makes it hard to perform esophagogastric anastomosis safely, and the reported rates of anastomotic leak vary from 5 to 16%. Several minimally invasive esophago-gastric anastomotic techniques have been described, but to date strong evidence to support one technique over the others is still lacking. We herein report the technical details and preliminary results of a new robot-assisted hand-sewn esophago-gastric anastomosis technique. METHODS: From January 2018 to December 2020, 12 cases of laparoscopic/thoracoscopic Ivor Lewis esophagectomy with robot-assisted hand-sewn esophago-gastric anastomosis were performed. The gastric conduit was prepared and tailored taking care of vascularization with a complete resection of the gastric fundus. The anastomosis consisted of a robot-assisted, hand-sewn four layers of absorbable monofilament running barbed suture (V-lock). The posterior outer layer incorporated the gastric and esophageal staple lines. RESULTS: The post-operative course was uneventful in nine cases. Two patients developed chyloperitoneum, one patient a Sars-Cov-2 infection, and one patient a late anastomotic stricture. In all cases, there were no anastomotic leaks or delayed gastric conduit emptying. The median post-operative stay was 13 days (min 7, max 37 days); the longest in-hospital stay was recorded in patients who developed chyloperitoneum. CONCLUSION: Despite the small series, we believe that our technique looks to be promising, safe, and reproducible. Some key points may be useful to guarantee a low complications rate after MIILE, particularly regarding anastomotic leaks and delayed emptying: the resection of the gastric fundus, the use of robot assistance, the incorporation of the staple lines in the posterior aspect of the anastomosis, and the use of barbed suture. Further cases are needed to validate the preliminary, but very encouraging, results.

Case Report: Management of Malignancy-Exacerbated Pemphigus Vulgaris During COVID-19 Pandemic.

Pemphigus vulgaris is an intraepidermal autoimmune mucocutaneous blistering disease whose etiopathogenesis includes various trigger factors, i.e., drugs and malignancies. We present a case of malignancy-exacerbated pemphigus vulgaris which required a careful diagnostic process in order to rule out paraneoplastic pemphigus, along with the challenges posed by the need of treating both cutaneous and oncologic diseases. Possible post-operative complications post-poned the start of first-line immunosuppressive treatment of pemphigus. Moreover, the infective risks had to be minimized during the peak of the COVID-19 pandemic in Italy. Intravenous immunoglobulins were chosen as "bridge" therapy before the tumor surgical excision, followed by rituximab in post-operative phase.
