The laparoscopic approach is the gold standard for acute appendicitis. There are several surgical devices to achieve hemostatic control of the appendicular artery (monopolar electrocautery, endoclip, endostapler, ultrasonic scalpel, and LigaSure™ vessel-sealing device), which vary widely according to the surgeon’s preference and availability in the institution. All devices are effective and safe, but monopolar electrocautery systems are the most cost-effective ones.
A 24-year-old woman was admitted to our emergency department with a 24-hour evolution of right iliac fossa pain. No other symptoms were noted. An abdominal ultrasound was suggestive of an acute appendicitis.
This full length surgical movie shows the feasibility and safety of monopolar electrocautery for meso-appendiceal dissection. The intra-abdominal procedure was achieved in 5 minutes 30 seconds.
No complications were observed and the patient was discharged home on the next postoperative day.

Laparoscopic right hemihepatectomy with augmented reality

We report the case of a 42-year-old woman who underwent a laparoscopic right hemihepatectomy for a hepatic metastasis. The intervention is begun with the exploration of the entire peritoneal cavity and an intraoperative ultrasound exam of the liver. The lesion is identified by means of augmented reality. Dissection of the different vascular structures is then performed at the level of the hepatic pedicle. A clamping test of the right branches is achieved. The right branch of the hepatic artery and the right portal vein are clamped, hence creating the demarcation area, which is identified by means of the coagulating hook. Declamping of portal and arterial structures coursing towards the right liver is achieved. The right branch of the portal vein is divided between two clips. The right branch of the hepatic vein is also divided between two clips. After mobilization of the right liver, the hepatotomy is begun. The first superficial centimeters are divided using an ultrasonic dissector (Ultracision®). Dissection is then carried on by means of a Cusa® Dissectron® Ultrasonic Surgical Aspirator. The largest structures are subsequently dissected intraparenchymally, and then clipped and divided. Hemostasis is completed using a radiofrequency instrument. The right biliary tract is dissected intraparenchymally, clipped and divided. The right hepatic vein is divided by means of a stapler. The specimen is placed in a bag, which is extracted by means of a small Pfannenstiel incision. Hemostasis is controlled as the pneumoperitoneum is reduced. A blade is positioned in the hepatectomy area.

Laparoscopic resection of an epiphrenic diverticulum

This video shows a laparoscopic resection of a large epiphrenic diverticulum and an esophageal myotomy with partial posterior fundoplication. Abdominal obesity as well as an accessory left hepatic artery originating from the left gastric artery make dissection of the right para-esophageal area difficult. An anterior phrenotomy as well as the posterior retro-esophageal dissection towards the aorta make dissection of the diverticulum possible. The upper limit of the diverticulum is strongly attached to the esophagus and the pleura, and its dissection is difficult. After complete dissection of the diverticulum and with the guidance of an intraoperative endoscopy, resection is performed. As it is believed that an underlying motility disorder is present, a distal esophageal myotomy and partial fundoplication is added. The postoperative course was uneventful and the patient has no remaining symptoms.

Robot-assisted thoracic resection of an extended esophageal leiomyoma

Objective:
Leiomyomas represent approximately 70% of all benign esophageal tumors. In most cases, patients are asymptomatic, but others can present chest pain, dysphagia or weight loss. Even if malignization is rare, surgery is indicated. Laparoscopy is the most common approach because of the frequency of leiomyoma localization on the lower esophagus. However, thoracoscopy is also commonly performed with some difficulties in case of large tumors.
Our objective is to demonstrate the robotic approach and the bipolar Maryland forceps used for such a specific lesion.

Case presentation:
We present the case of a 58-year-old woman with no particular co-morbidity. On CT-scan, she was incidentally diagnosed with a leiomyoma for Guillain-Barre syndrome. A homogeneous 7cm tumor was found on the left side of the middle esophagus with a horseshoe-shaped aspect typical of leiomyoma. Check-up was completed by MRI and endoscopic ultrasonography, which tended to confirm the diagnosis.
In this video, the robot-assisted thoracic enucleation of the tumor performed by a left approach shows the quality of esophageal exposure and tumor dissection by means of a bipolar Maryland forceps. Blood loss was less than 30mL, and the postoperative period was uneventful. Histological analysis confirmed the diagnosis of leiomyoma.

Conclusion:
Robot-assisted resection of benign esophageal tumors is a safe procedure, especially for intrathoracic tumors. This technique provides a better view and easier dissection. The use of a bipolar Maryland forceps allows for a safer procedure. Day care surgery could then be expected for smaller lesions.

Laparoscopic ventral mesh rectopexy in a male patient

Introduction
Ventral rectopexy, with or without mesh, has a lower recurrence rate than a perineal approach for rectal prolapse treatment. One of the techniques which are gaining a wider acceptance is the laparoscopic ventral mesh rectopexy, also called D'Hoore rectopexy. The unique feature of this technique is that it avoids any posterolateral dissection of the rectum. Clinical outcomes demonstrate that this technique present good results in terms of recurrence, a low rate of constipation induced by the procedure, as well a low risk of sexual dysfunction.

Clinical case
A 43-year-old man was admitted to our hospital with a one-year evolution of rectal prolapse with complaints of sporadic rectal bleeding and soiling. He reports daily bowel movements with a necessity of manual prolapse reduction. His past medical history includes follicular lymphoma. He has no history of previous surgeries.
After preoperative investigation with colonoscopy, a barium enema and anorectal function tests, a laparoscopic D’Hoore rectopexy was proposed to the patient.
In this video, we present the critical steps of the procedure with special attention to the preservation of the hypogastric nerves.
The postoperative outcome was uneventful. In the follow-up period, the patient reports a significant improvement of symptoms, without rectal prolapse at defecation, no constipation, and no change in sexual function.

Manual colorectal anastomosis during suprapubic single incision laparoscopic left hemicolectomy

Background: Single incision laparoscopic left hemicolectomy is a feasible procedure. A suprapubic access allows to offer satisfactory cosmetic results in case of an extended scar due to a large tumor. An intracorporeal circular mechanical anastomosis is the most common type. A manual anastomosis is feasible and allows to control lumen opening, potential bleeding, and overall to overcome the difficulty of transanal stapler insertion in case of high rectal transection.
Video: This video shows two different types of manual colorectal anastomosis, through a right suprapubic access.
1) Double-layer end-to-end
2) Monolayer end-to-end
Results: After an appropriate learning curve, time to perform the manual anastomosis is 40 minutes.
Conclusions: Different colorectal anastomoses can be performed and the surgeon has to choose the appropriate one, case by case.

Pure NOTES total transanal caudal-to-cranial low rectal resection

A 37-year-old female patient underwent a pure NOTES transanal rectal resection without transabdominal laparoscopic assistance for a rectal lesion located 5cm away from the anal verge (cT2N0M0 adenocarcinoma). All oncologic principles were fulﬁlled.
A GelPOINT Path Transanal® access platform was used. The procedure was achieved with no-flexible cameras and straight laparoscopic instruments. An Ultracision® device was used for dissection. A circular stapler with a long anvil was selected because it helped to achieve the anastomosis.
No complications were observed and the patient was discharged home on the third postoperative day.
