Abstract Background During peroral endoscopic myotomy (POEM), use of traditional instruments leads to an increase in overall time of procedure due to constant exchange of instruments. Speedboat-RS2 (Creo-Medical, UK) is a novel device which has shown promising results for endoscopic submucosal dissection of gastrointestinal lesions, but its feasibility, and safety for POEM is unexplored. Methods Data from patients who had undergone POEM for achalasia cardia utilizing Speedboat-RS2 was reviewed. Results Two patients with mean age of 46 years and mean symptom duration of 3 years were included. Both patients had type II achalasia diagnosed on esophageal manometry. One patient underwent anterior myotomy and the other posterior approach. Submucosal tunneling (~15 cm) was achieved in a mean of 20 minutes, myotomy (~ 9 cm) in 8 minutes and the entire procedure was completed in a mean of 30 minutes with 100 % technical success. Both patients were discharged the day after the procedure without any immediate adverse events. At 6 weeks, endoscopy was uneventful and the patients were asymptomatic. Conclusions Early experience shows that Speedboat-RS2 is feasible for performing POEM with good safety profile. Submucosal tunneling was relatively quick and coagulation was effective. Long term studies with a larger patient cohort are warranted.

Energy based devices have been developed for the purposes of tissue contraction and skin tightening. Its application in the face and neck have been explored using lasers, temperature controlled monopolar and bipolar radiofrequency, and ultrasound. The purpose of this chapter is to explore the various applications for the face and neck using Renuvion™, a unique energy driven device based on plasma generated from the combination of helium gas and radiofrequency energy. The advantage of this technology is its ability to offer precise delivery of heat to tissue with minimal thermal spread, in part due to the rapid cooling aided by the helium gas. We will explore the options in which this technology can be incorporated to rejuvenate the face and neck, the patient selection considerations in choosing method of approach, surgical technique, anticipated outcomes, potential concerns and or complications associated with this and expected perioperative care. Applications in the face and neck include: (1) Subdermally in the neck as a stand alone procedure with or without liposuction. (2) Subdermally in a limited incision, non-excisional technique with a concomitant platysmaplasty either with an open approach or percutaneous use of suture suspension for the platysmal muscle. (3) Subdermally in conjunction with an open traditional rhytidectomy involving skin excision. (4) Ablative resurfacing—fractional or pulsed and full continuous modalities (non-FDA cleared at the time of this writing). It is the authors’ experience that with appropriate patient selection this can be a powerful tool that can deliver skin tightening and rhytid reduction not seen by other technologies available.

Objective The Cox-Maze procedure (CMP) for the surgical treatment of atrial fibrillation (AF) traditionally has required a median sternotomy and cardiopulmonary bypass. This study describes a method using ablation technologies to create the full Cox-Maze lesion set through a 5- to 6-cm right minithoracotomy. Methods Twenty-two consecutive patients underwent a CMP through a right mini-thoracotomy and cardiopulmonary bypass. All patients were followed prospectively with electrocardiogram and 24-hour Holter monitoring at 3, 6, and 12 months. The CMP lesion set was created using bipolar radiofrequency energy and cryotherapy. Results There was no operative mortality or major complications. Two patients required a permanent pacemaker. Five patients (23%) had early atrial tachyarrhythmias. At last follow-up (mean, 18 ± 12 months), all the patients (n = 22) were free from atrial dysrhythmias. At 3 months (n = 19), 84% of patients were off antiarrhythmic drugs. At 6 months (n = 18), 94% of patients were free from AF and off antiarrhythmic medications. At 12 months (n = 16), 81% of patients were free from AF and off antiarrhythmic drugs and three patients remained on warfarin for a mechanical mitral valve. Conclusions A full CMP can be performed through a right mini-thoracotomy with outstanding short-term results. This less invasive procedure can be offered to patients without compromising efficacy.
