Second reoperative antireflux procedure for valve slippage
Redo surgery is technically more demanding than primary fundoplication. In addition, anatomical defects that caused failure may increase technical difficulties. A recent review found that the average success rate after laparoscopic redo operations ranged from 65 to 100 per cent (van Beek D, Auyang E, Soper N. A comprehensive review of laparoscopic redo fundoplication. Surgical Endoscopy: Springer New York; 2010. p 1-7). However, our recent study showed that the failure rate after re-operation is increasing with time, and highlighted the need for accurate preoperative and intraoperative assessment of the causes of failure (Dallemagne B, Arenas Sanchez M, Francart D, Perretta S, Weerts J, Markiewicz S, et al. Long-term results after laparoscopic reoperation for failed antireflux procedures. Br J Surg 2011;98:1581-7). This video shows a third antireflux procedure in a patient presenting with slippage of the fundoplication.

Primary hyperparathyroidism cure using 3D CT-scan reconstruction
Parathyroid surgery has largely benefited from advances in preoperative imaging modalities allowing to determine potential adenomas. Conventionally, ultrasonography and scintigraphy with 99mTc-sestamibi (MIBI) provide sufficient information to guide the surgical procedure. Specific software has been developed at the IRCAD to allow for the 3D reconstruction of the entire cervical structures. The handling of such reconstruction helps to perform a precise preoperative assessment. Arterial reconstruction allows to predict the existence of an arteria lusoria and of a non-recurrent recurrent nerve. In this case, the position of a potential adenoma in relation to the inferior thyroid artery allows to anticipate that it is not an adenoma but a thyroid nodule. A second potential target is visualized inferiorly. These two potential locations will be explored during the video-assisted surgical intervention.

Single stage laparoscopic management of common bile duct stones with acute cholecystitis
Ten to 18% of patients undergoing cholecystectomy for gallstones have common bile duct (CBD) stones. Treatment options for these stones include pre- or post-operative endoscopic retrograde cholangiopancreatography (ERCP), open surgery, or laparoscopic surgery.
The first option depends mainly on the availability of an experienced endocopist who could successfully clear stones in most patients. However no stones are found in 20% to 60% of cases. In such patients, rare and unpredictably severe ERCP morbidity can occur.
Thanks to progress in laparosocopic techniques, associated with technological developments, the single stage laparoscopic management of CBD and gallbladder stones has become one of the main options for the treatement of choledocholithiasis associated with cholelithiasis.
After the analysis of local conditions and the interpretation of intraoperative cholangiography images it is fundamental to decide which type of access to use to get to the main biliary tract, either transcystic access or directly through choledochotomy.

Management of transpyloric invagination of a gastrointestinal stromal tumor (GIST)
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. GISTs are most commonly found in the stomach (40-70%), but can occur in all other parts of the GI tract, with 20 to 40% of GISTs arising in the small intestine and 5 to 15% from the colon and rectum.
They typically grow endophytically, parallel to the bowel lumen, commonly with overlying mucosal necrosis and ulceration. They also vary in size, from a few millimeters to 40cm in diameter. Many GISTs are well defined by a thin pseudo-capsule.
Over 95% of patients present with a solitary primary tumor, and in 10 to 40% of these cases, the tumor directly invades neighboring organs. Gastric GISTs are usually presented with GI bleeding and abdominal pain. However, most patients are symptom-free and the lesions are discovered incidentally during an upper endoscopy performed for other reasons (chronic abdominal pain and intermittent gastric obstruction in this patient).
Surgery remains the mainstay of curative treatment.
Surgical resection of localized gastric GISTs is the preferred treatment modality, as resection of the tumor renders the only chance for cure at this time. Historically, a 1 to 2cm margin was thought to be necessary for an adequate resection. However, more recently, DeMatteo et al. demonstrated that tumor size and not negative microscopic surgical margins determine survival.
It is therefore accepted that the surgical goal should be a complete resection with gross negative margins only.
Given this, wedge resection has been advocated by many investigators for the majority of gastric GISTs.

Loop-and-let-go technique for symptomatic descending colonic lipoma
Large symptomatic colonic lipomas require treatment, but resection of lipomas by means of endoscopic cautery snare carries some risk of colonic perforation. The loop-and-let-go technique described here is technically simple; anyone who is well acquainted with the snare cautery technique can do it. It looks safer than the conventionally employed snare cautery technique, as no current is used with the loop-and-let-go technique. It causes selective occlusive ischemia of mucosa and submucosa without causing any transmural damage. The total duration needed for the lipoma to slough off depends on the quality of endoloop occlusion and the type of lipoma (narrow-based vs wide-based).

Laparoscopic management of gangrenous perforated cholecystitis
Laparoscopic cholecystectomy is the gold standard for symptomatic cholecystolithiasis. Technical maturation and advances in instrumentation have enabled the application of this procedure for acute cholecystitis.
This video demonstrates the surgical approach to performing a laparoscopic cholecystectomy in an older male patient with acute cholecystitis and who has had a previous laparotomy for vascular surgery. The surgeon uses a French approach standing between the patient's legs while he optical trocar is placed supraumbilically, 3cm to the right of the midline in order to avoid the adhesions caused by the previous surgery.
An ischemic gallbladder with necrotic area and infundibular perforation was found.
