[Pure laparoscopic DP-CAR procedure with portal vein resection]. / Polnost'yu laparoskopicheskaya dp-car s rezektsiei vorotnoi veny (klinicheskoe nablyudenie).

OBJECTIVE: To improve short- and long-term outcomes of locally advanced pancreatic body-tail cancer followed by major vessels invasion. MATERIAL AND METHODS: A case report of pure laparoscopic DP-CAR procedure with portal vein resection for locally advanced pancreatic body-tail cancer followed by severe abdominal pain in a 49-year-old patient is presented. RESULTS: Liver or stomach ischemia was not observed. Portal wall resection wasn't associated with any complication and resulted R0-resection. Postoperative period was complicated by Grade B pancreatic fistula. Preoperative abdominal pain completely disappeared after surgery. Surgery time was 330 min, intraoperative blood loss - 300 ml. The patient is currently undergoing FOLFIRINOX adjuvant chemotherapy. CT in 90 days after surgery confirmed no progression of disease or liver/stomach blood supply congestion. CONCLUSION: Modern technologies provide the opportunity to perform pure laparoscopic advanced surgical procedures with major vessels resection. Pure laparoscopic DP-CAR procedure with portal vein resection is effective and safe procedure that can be performed with all principles of open surgery and is associated with acceptable short- and long-term results.

Distal Pancreatectomy with Celiac Axis Resection (DP-CAR) for Pancreatic Cancer. How I do It.

Approximately 30% of all pancreatic cancer patients have locally advanced (AJCC stage 3) disease. A sub-group of these patients-where the cancer only involves the celiac axis-may benefit from distal pancreatectomy with celiac axis resection (DP-CAR). Previous studies have shown that DP-CAR offers a survival benefit to a selected group of patients with otherwise unresectable pancreatic cancer, when performed by experienced pancreatic cancer treatment teams at high-volume centers. This article proposes a standardized approach to DP-CAR, including routine neoadjuvant (FOLFIRINOX) chemotherapy. This approach to selecting patients and performing DP-CAR has the potential to improve short-term outcomes and overall survival in selected patients, but it should be reserved for high-volume centers.

[Topical pharmacologic approach with 5% lidocaine medicated plaster in the treatment of localized neuropathic pain]. / Approccio farmacologico topico con lidocaina cerotto 5% nel trattamento del dolore neuropatico localizzato.

The treatment of neuropathic pain is a medical challenge. The responsiveness to the different classes of drugs is often unsatisfactory and frequently associated to a wide range of side effects. International guidelines suggest for the "localized" neuropathic pain the topical treatment with 5% lidocaine medicated plaster, alone or associated to systemic drugs, as the first choice since its favorable efficacy and tolerability profile. Many clinical experiences support the rationale for using 5% lidocaine medicated plaster in different kinds of localized neuropathic pain, such as postherpetic and trigeminal neuralgia, compressive syndromes, painful diabetic polyneuropathy and pain secondary to trauma or surgical interventions. This paper reports a series of clinical cases whose heterogeneity suggests the wide burden of applicability of the topical 5% lidocaine, either alone and associated to systemic drugs. All the described conditions were characterized by a highly intense pain, not adequately controlled by actual medications, which improved after the use of topical lidocaine. The good response to lidocaine allowed the reduction, of even the withdrawal, of concurrent drugs and improved the patients' quality of life.

Mesenteric shunting decreases visceral ischemia during thoracoabdominal aneurysm repair.

PURPOSE: A technique to decrease visceral ischemic time during thoracoabdominal aneurysm (TAA) repair is reported. METHODS: A 10 mm Dacron side-arm graft is attached to the aortic prosthesis and positioned immediately distal to the planned proximal thoracic aortic anastomosis. On completion of the anastomosis, a 16 to 22 Fr perfusion catheter is attached to the side-arm graft and inserted into the orifice of the celiac axis or superior mesenteric artery. The cross-clamp is then placed on the aortic graft distal to the mesenteric side-arm graft. Pulsatile arterial perfusion is thus established to the visceral circulation while intercostal anastomoses or reconstruction of celiac, superior mesenteric, and right renal arteries is performed. Visceral ischemic time and the rise in end-tidal Pco2 after reconstruction of the visceral vessels in patients with mesenteric shunting was compared with a control group matched for aneurysm extent and treated immediately before use of the mesenteric shunt technique. RESULTS: Between July and Oct, 1996, the technique was applied in 15 patients undergoing type I, II, or III TAA repair with a clamp and sew technique. The mean decrease in systolic arterial pressure was 12.5 +/- 8.5 mm Hg, with a concomitant rise in end-tidal Pco2 (mean, 6.9 +/- 5.8 mm Hg), after perfusion was established through the mesenteric shunt. Mean time to establishment of visceral perfusion through the shunt was 25.5 +/- 4.4 minutes; the resultant decrement in visceral ischemic time averaged 31.3 minutes (i.e., until celiac, superior mesenteric, and right renal arteries were reconstructed). Compared with controls, patients with shunts had a significantly decreased (6.9 +/- 5.8 versus 21.6 +/- 8.4 mm Hg; p = 0.0003) rise in end-tidal CO2 on completion of visceral vessel reconstruction. CONCLUSIONS: In-line mesenteric shunting is a simple method to decrease visceral ischemia during TAA repair, and it is adaptable to clamp and sew or partial bypass and distal perfusion operative techniques.
