Robot-assisted left adrenalectomy for Conn's adenoma
As laparoscopy is the standard approach to perform an adrenalectomy, robotic assistance is considered as an effective tool to perform this resection. Surgical steps follow those established for laparoscopy (i.e., mobilization of the spleen and of the pancreas in a patient placed in a lateral position, identification of the renal vein, control and division of the adrenal vein, successive freeing of the medial, external, inferior, and finally posterior aspects of the gland. The sealing devices such as ultrasonic dissectors are well adapted to perform this resection, and to safely control adrenal arteries. Robotic assistance takes full benefit from the degrees of freedom of the tips of the instruments and allows for an easy adrenal gland mobilization and removal.

Challenges in GERD: Collis fundoplication in a patient with a BMI of 41
Obesity has long been considered a predisposing factor for gastroesophageal reflux. It is also thought to predispose patients to a poorer clinical outcome following antireflux surgery and some authors recommend gastric bypass in obese patient with symptomatic GERD. However, some studies reported that preoperative BMI does not influence the clinical outcome following laparoscopic antireflux surgery and concluded that obesity is not a contraindication for laparoscopic fundoplication (1, 2).
In this video, we present a Collis-Toupet gastroplasty in a woman with a BMI of 41.

Laparoscopic rectovaginal resection for endometriosis: transvaginal specimen extraction and anastomosis
The authors demonstrate a rectovaginal resection technique for invasive endometriosis. The original nature of this approach hinges on the mesorectum dissection technique in contact with the rectal wall in order to preserve rectal vascularization and innervation. Additionally, rectal exteriorization through the vagina to prepare for the colorectal anastomosis using a mechanical circular stapling without any abdominal incision is truly original as it contributes to limiting parietal trauma and improving cosmesis. The film truly focuses on the digestive approach just after anterior pelvic dissection has been completed by the team of gynecologic surgeons.

Laparoscopic gastric pull-up in long-gap esophageal atresia
This is the case of a 2-year-old male preschooler, diagnosed with type III esophageal atresia. During the neonatal period, the patient had a right thoracotomy. Ligation of a tracheo-esophageal fistula and an esophago-esophagostomy were carried out, but failed because there was a long gap atresia. The measured gap of four vertebrae confirmed the diagnosis of long gap esophageal atresia; upon its evaluation by a multidisciplinary team, a laparoscopic gastric pull-up was carried out using 4 trocars: one 12mm, two 5mm and one 3mm trocar. The 6-hour duration of surgery was due to a firm adhesion of the esophagus to the posterior mediastinum. The patient had a favorable outcome without major complications. He remained in PICU for 72 hours and was extubated 48 hours after surgery. This is the sixth case of this particular pediatric surgeon and although our follow-up is still underway, we believe that laparoscopic pediatric surgeons with a certain degree of experience would be able to reproduce this technique, which is an excellent therapeutic option for the management of long gap esophageal atresia with good postoperative results.

Middle lobectomy for a typical carcinoid tumor using 4 robotic arms
We present the case of a 78-year-old woman with a typical carcinoid tumor of the middle lobe of the lung. Bronchoscopy was carried out. A tumor lying in the deep segment of the middle lobe bronchus was identified by biopsy as a typical carcinoid tumor. We decided to perform middle lobectomy using a four-arm robotic assistance as it allows for a minimally invasive surgery.

The patient is intubated with a double lumen tracheal tube. The patient is placed in a left-sided decubitus with the right arm hanging. Anesthesiologists and mechanical ventilation need to be placed on the patient’s right side. This will provide sufficient room to approach the robot on the left side with a 30-degree angulation to the patient’s head.

The robotic procedure was uneventful and was fully carried out. Chest tube drainage was removed on postoperative day 2 and the patient was discharged on postoperative day 7.

Technique for endoscopic resection of obstructive endobronchial malignancy
Invasion of the tracheo-bronchial tree by a malignant pulmonary lesion is the most frequent cause of bronchial obstruction in the adult. Malignant obstruction of major airways may require endoscopic resection for rapid palliation of dyspnea and obstructive pneumonitis.
Patients should be evaluated with flexible bronchoscopy and computed tomography of the chest to assess the anatomy of the obstruction and demonstrate patent airway distally. This criterion is critical for optimal selection.
Resection is carried out in the operating room under general anesthesia. It is important to emphasize that close collaboration between the surgical and anesthesia teams is essential at all times, as they are sharing responsibility for the airway. We use rigid bronchoscopy for piecemeal extraction of the lesion. Since moderate bleeding may be encountered, the clinician should be familiar with hemostatic manoeuvres including dabbing raw bronchial surfaces using the rigid bronchoscope, the use of epinephrine soaked pledgets, and irrigation using epinephrine solution. Hemostasis may also be accomplished using energy sources delivered through a flexible bronchoscope, including electrocautery, argon beam, and Nd:YAG laser. All energy sources should be used with caution within the airway to minimize the risk of complications.
Depending on the individual patient, endobronchial resection may be combined with airway stenting and/or postoperative chemoradiotherapy. In carefully selected patients, this will result in adequate palliation of symptoms.
Acknowledgment: we would like to thank Nathalie Leroux RN and Suzanne Desbiens RN for their continued support.

Transumbilical single incision laparoscopic left ovariectomy
Background: Transumbilical single incision laparoscopy has been reported to be a feasible and safe procedure to treat gynecologic diseases. This video presents a left ovariectomy performed in a patient with a symptomatic giant ovarian cyst.

Clinical case: A 56-year-old female with a body mass index of 20.5 kg/m2, was consulted for abdominal pain localized in the left iliac fossa. Preoperative work-up showed a left ovarian cyst of 12cm in diameter. The cyst appeared to be round, with smooth walls, homogenic liquid, and without intracystic proliferations. The procedure was performed using an 11mm reusable port for a 10mm, 30-degree standard length scope, and curved reusable instruments according to Dapri (Karl Storz Endoskope). The specimen was extracted through the umbilicus in a custom-made plastic bag.

Results: No conversion to open surgery nor additional ports were necessary. The laparoscopy lasted 37 minutes and the final umbilical incision length was 15mm. Pathological data revealed a serous cystadenoma. The patient was discharged on postoperative day 1. At 7-month follow-up, no late complications were found and the patient was asymptomatic.

Conclusions: Transumbilical single incision laparoscopy is beneficial for gynecologic diseases and this technique allow for a final scar of minimal size. The cost of the procedure is similar to that of multi-port laparoscopy.
