Thoracoscopic and laparoscopic radical esophagectomy with lateral-prone position

Minimally Invasive Esophagectomy in Semi-Prone Position (Pawar Technique): Technical Aspects and Outcome in 224 Patients

Background and Objectives  There are two patient positions described for minimally invasive esophagectomy (MIE) for esophageal cancer, viz., left lateral and prone positions. To retain the benefits and overcome the disadvantages of these positions, a semi-prone position was developed by us. Our objective was to analyze the feasibility of performing MIE in this position.

Materials and Methods  A retrospective review of patients who underwent MIE at our center from January 2007 to December 2017 was done. A semi-prone position is a left lateral position with an anterior inclination of 45 degrees. Intraoperative parameters including conversion rate, immediate postoperative outcomes, and long-term oncological outcomes were analyzed.

Statistical Analysis  Statistical Package for the Social Sciences version 19 (IBM SPSS, IBM Corp., Armonk, New York, United States) was utilized for analysis. Survival analysis was done using Kaplan-Meier graph. Quantitative data were described as mean or median with standard deviation, and qualitative data were described as frequency distribution tables.

Results  Consecutive 224 patients with good performance status were included. After excluding those who required conversion (14 [6.6%]), 210 patients were further analyzed. Median age was 60 years (range: 27–80 years). Neoadjuvant treatment recipients were 160 (76%) patients. Most common presentation was squamous cell carcinoma (146 [70%]) of lower third esophagus (140 [67%]) of stage III (126 [60%]). Median blood loss for thoracoscopic dissection and for total operation was 101.5 mL (range: 30–180 mL) and 286 mL (range: 93–480 mL), respectively. Median operative time for thoracoscopic dissection alone was 67 minutes (range: 34–98 minutes) and for entire procedure was 215 minutes (range: 162–268 minutes). There was no intraoperative mortality. Median 16 lymph nodes were dissected (range: 5–32). Postoperative complication rate and mortality was 50% and 3.3%, respectively. Disease-free interval was 18 months (range: 3–108 months) and overall survival was 22 months (range: 6–108 months).

Conclusion  MIE with mediastinal lymphadenectomy in a semi-prone position is feasible, convenient, oncologically safe, which can combine the benefits of the two conventional approaches. Further prospective and comparative studies are required to support our findings.

Total minimally invasive McKeown esophagectomy in an esophageal cancer patient with situs inversus totalis: A case report

Situs inversus totalis (SIT) is an extremely rare anomaly characterized by a left‐to‐right reversal of all the thoracic and abdominal organs. Only 11 cases of esophageal cancer with SIT have been reported worldwide, most of which underwent hybrid minimally invasive esophagectomy (MIE) but not total MIE. Here, we report a case of esophageal cancer with SIT successfully treated by total MIE, with a right lateral‐prone position adopted during the thoracic procedure. The relevant literature is also discussed and reviewed.

Ergonomic thoracic port design for video-assisted thoracoscopic minimally invasive esophagectomy and lymphadenectomy: a preliminary pilot study

Background

Video-assisted minimally invasive esophagectomy (MIE) has been widely applied in clinical practice. However, the optimal port design for thoracoscopic esophagectomy and lymphadenectomy has not been well established. Here we introduced our novel ergonomic thoracic port design as well as our novel procedures of lymphadenectomy via tissue interactive retraction and compared its effects with that of conventional port design in this pilot study.

Methods

Patients undergoing McKeown MIE from January 2018 to December 2018 in one surgical team were randomly assigned into the ergonomic port design group and conventional port design group. Data of baseline characteristics, perioperative outcomes, and ergonomic assessment were collected and compared between the two groups.

Results

A total of 70 patients undergoing curative McKeown MIE were randomly assigned and there were 35 patients in each group. The baseline characteristics between the two groups were comparable and well-matched. Moreover, there was no significant difference of number of total dissected lymph nodes, positive lymph nodes and total dissected mediastinal lymph nodes between the two groups. As for perioperative outcomes, there was also no significant difference of in-operating time and blood loss in the thoracic part between the two groups. However, there were significantly less times of forced pause of the surgeon by fatigue during thoracic part in the ergonomic group compared to conventional group (mean time: 1.1 vs. 7.4, respectively; P<0.001) and the symptom score referable to the musculoskeletal system by the surgeon was significantly lower in the ergonomic group than in the conventional group (2.3 vs. 7.6; P<0.001). Postoperatively, there was no significant difference of hospital stay duration and rate of complication and 30-day mortality between the two groups.

Conclusions

Our novel thoracoscopic port design and procedures of lymphadenectomy was proved to be feasible and ergonomic, which could be easily mastered by most of the thoracic surgeons.
