Three-trocar laparoscopic right ileocolectomy for advanced small bowel neuroendocrine tumor
Background: Minimally invasive surgery (MIS) was shown to offer advantages in general and oncologic surgery (1). Over the last decade, reduced port laparoscopy (RPL) has been introduced to reduce the risks related to ports and abdominal wall trauma, with enhanced cosmetic outcomes (2). In this video, the authors report the case of a 59-year-old man with a small bowel neuroendocrine tumor, and who underwent a three-trocar right ileocolectomy.
Video: Preoperative work-up, including endoscopic ultrasound, octreoscan, PET-scan, and FDG PET-CT, showed a 15mm small bowel tumor with mesenteric and transverse mesocolic extension, until the muscularis propria of the third portion of the duodenum. The biopsy revealed a low-grade well-differentiated neuroendocrine tumor. The procedure was performed using three abdominal trocars: a 12mm one in the umbilicus, a 5mm one in the right flank, and a 5mm port in the left flank (Figure 1). Abdominal cavity exploration demonstrated the presence of a tumor located in the mesentery of the last small bowel loop, with consequent bowel retraction, dislocation of the caecum and appendix, located under the right lobe of the liver, and tumoral extension into the proximal transverse mesocolon. After mobilization of the right colon from laterally to medially, the second and third duodenal segments were exposed, showing tumor extension towards the anterior duodenal wall of these segments. After encircling the anterior aspect of the duodenal wall with a piece of cotton tape (Figure 2), an endoscopic linear stapler was inserted through the umbilical trocar under the visual guidance of a 5mm scope in the left flank (Figure 3a), and it was fired (Figure 3b). The specimen was removed through a suprapubic access. Perioperative frozen section biopsy showed a free duodenal margin, and the procedure was subsequently completed with an ileocolic anastomosis, performed in a side-to-side handsewn intracorporeal fashion. At the end, the mesocolic defect was closed.

Results: Operative time was 4 hours. No added trocars were necessary. The postoperative course was uneventful and the patient was discharged on postoperative day 4. Pathological findings showed a grade I well-differentiated small bowel neuroendocrine tumor, with lymphovascular emboli and perinervous infiltration (1/20 metastatic nodes, free margins, stage: pT3N1 (8 UICC edition). A follow-up under somatostatin therapy was put forward.

Conclusions: RPL is a feasible option when performing advanced oncological surgery. Patients benefit from all MIS advantages, including reduced trocar complications and enhanced cosmetic outcomes.

Endoscopic ultrasound-guided choledochoduodenostomy with a lumen-apposing metal stent
This video demonstrates a case of EUS-guided choledochoduodenostomy, emblematic of the latest cutting-edge technology.
A 86-year-old woman with recent abdominal pain and jaundice underwent a CT-scan, which showed an enlarged tumor of the second portion of the duodenum with biliary tree dilatation. Gastroscopy with biopsy confirmed the diagnosis of duodenal adenocarcinoma of the 2nd duodenum.
First, endoscopic retrograde cholangiopancreatography (ERCP) failed to achieve biliary drainage because of an inability to cannulate the papilla due to tumor infiltration. EUS-guided hepatogastrostomy (EUS-HGS) was not attempted because the left intra-hepatic bile ducts were minimally dilated (3mm). However, the common bile duct (CBD) was largely dilated (20 mm). A Hot AXIOS™ Stent and Electrocautery Enhanced Delivery System (stent of 8 by 6mm) was advanced through the bulb. Pure cut electrocautery current was then applied, allowing the device to reach the CBD. Next, the distal flange was opened and retracted towards the EUS transducer, and once a biliary and bulbar tissue apposition had been noted, the proximal flange was released. Good drainage of purulent bile was observed and no complications occurred during the procedure and one month afterwards.

Transanal minimally invasive full-thickness middle rectum polyp resection with the patient in a prone position
Background: Nowadays, rectal preservation has gained popularity when it comes to the management of degenerated rectal polyps or early rectal cancer (1, 2). Tis/T1 rectal lesions can be safely treated without chemoradiation (3). Treatment via transanal minimally invasive surgery (TAMIS) offers more advantages than endoscopic submucosal dissection (ESD) (4). The authors report the case of a 60-year-old woman who underwent a TAMIS procedure for a large polyp located anteriorly in the middle rectum, which was 7cm away from the pectineal line and staged as uTisN0M0 preoperatively.
Video: The patient was placed in a prone position with a split-leg kneeling position. A reusable transanal D-Port (Karl Storz Endoskope, Tuttlingen, Germany) was introduced into the anus together with DAPRI monocurved instruments (Figure 1). The polyp was put in evidence (Figure 2) and resection margins were defined circumferentially using the monocurved coagulating hook. A full-thickness resection was performed with a complete removal of the rectal serosa and exposure of the peritoneal cavity, due to the anatomical polyp positioning (Figure 3). The rectal opening was subsequently closed using two converging full-thickness running sutures using 3/0 V-loc™ sutures (Figure 4a). The two sutures were started laterally and joined together medially (Figure 4b).
Results: Total operative time was 60 minutes whereas suturing time was 35 minutes. There was no perioperative bleeding. The postoperative course was uneventful, and the patient was discharged after 2 days. The pathological report showed a tubular adenoma with high-grade dysplasia and clear margins.
Conclusions: In the presence of degenerated rectal polyps, full-thickness TAMIS is oncologically safe and feasible. The final rectal flap can be safely closed by means of laparoscopic endoluminal sutures.
