Penectomía parcial y reconstrucción peneana. Manejo quirúrgico inicial del cáncer de pene localizado

IntroductionSurgical management for penile carcinoma is mutilating and affects significantly quality of life. Hereby we present our experience on penile reconstruction (PR) immediately after oncologic resection.Materials and methodsWe included all patients from January 2007 until April 2012 who underwent PR after partial penectomy (PP). Patients included in the study were seen at four different hospitals. All procedures were done by the same surgeon. Information included were: oncological status at the moment of surgery, surgical technique used for reconstruction. Each case was also registered photographically. On follow-up visits data about outcome and patient's satisfaction were registered.ResultsDuring the study period 15 patients underwent PR. Average age at the moment of surgery was 49 years. Average follow-up was 15 months. In 12 patients PR was made at the same time as PP. Of those, four cases underwent glans resurfacing, 2 glandectomy, 6 partial penectomy, and the remaining 3 have had PP in a different time in the past. Every case underwent a split thickness graft procedure. Only 2 patients had postoperative complications. One of them presented urethral stricture and the other graft ischemia. Three patients had positive nodes at the moment of PP and two during the follow-up. None of the cases have presented local recurrence and only one died. On follow-up the remaining patients refer a good quality of life and felt happy with aesthetic results.ConclusionsGiven the results presented hereby we propose that PR must be part of the same procedure as the PP.     

Laparoscopy-assisted total gastrectomy with trans-orally inserted anvil(OrVilTM):A single institution experience

AIM:To investigate the feasibility of laparoscopyassisted total gastrectomy(LATG)using trans-orally inserted anvil(OrVilTM)in terms of operative characteristics and short term outcomes. RESULTS:Characteristics of 27 patients with gastric cancer who underwent LATG from October 2009 to October 2012 in the Foshan Affiliated Hospital of South Medical University were retrospectively reviewed. Among these patients,six were reconstructed by minilaparotomy and 21 by OrVilTM.The clinicopathological characteristics,total operation time,total blood loss, abdominal incision and complications of anastomosis including stenosis and leakage,were compared between the groups undergoing LATG with OrVilTM and the group undergoing minilaparotomy. RESULTS:The operations were successfully performed on all the patients without intraoperative complications or conversion to open surgery.Two(10%)patients received palliative procedure under laparoscope who were prepared for LATG preoperatively.One case had hepatic metastatic carcinoma and 1 case had tumor recurrence near the anastomosis 8 mo after surgery.The mean follow-up duration was 10 mo(range,2-24 mo). Operation time was significantly reduced by the use of OrVilTM(198.42±30.28 min vs 240.83±8.23 min). The postoperative course with regard to occurrence of stenosis and leakage was not different between the two groups.There were no significant differences in estimated blood loss.The upper abdominal incision was smaller in OrVilTM group than in minilaparotomy group (4.31±0.45 cm vs 6.43±0.38 cm). CONCLUSION:LATG using OrVil TM is a technically feasible surgical procedure with sufficient lymph node dissection,less operation time and acceptable morbidity.     

RECONSTRUCTION OF A NATURAL-LOOKING UMBILICUS

Based on the assumption that the umbilicus is a wound that has healed by second intention, we describe a method of reconstruction. The procedure consists of complete resection of the umbilical scar and its reconstruction by a linear incision at the site of the new umbilicus and inversion of the skin hedges, which are sutured to the linea alba leaving a 1 cm space between the skin borders to cause secondary wound healing. This procedure provides a natural-looking umbilicus. It is easy and quick to do, and can be used for reconstruction after abdominoplasty, excision of a naevus, or when the umbilicus has been removed during a previous xiphopubic incision.

目的 评估CT血管成像三维重建在布加综合征中的应用价值。方法 选取2011年2月至2013年12月就诊的布加综合征患者93例为研究对象,采用CT血管成像技术评估其门静脉、下腔静脉及肝静脉病变情况。结果 所有患者中,病变累及下腔静脉者(Ⅰ型和Ⅲ型)69例(74.19%),下腔静脉隔膜形成者34例(49.28%);肝静脉受损者(Ⅱ型和Ⅲ型)59例(63.44%),肝静脉隔膜形成者15例(25.42%);另有2例患者下腔静脉和肝静脉均有隔膜形成。56例(60.22%)患者存在侧支循环,食管胃底静脉曲张阳性39例(41.94%),脾脏肿大73例(78.49%),腹水36例(38.71%),肝脏尾状叶增大8例(8.6%),肾静脉血栓形成6例(6.45%)(双侧受累2例,单侧受累4例),原发性肝细胞癌5例(男性4例,女性1例)。结论 CT血管成像三维重建技术能够较好地反映布加综合征影像学特征,对布加综合征的临床诊疗具有较好的指导意义。     

Free Bipedicled Radial Forearm and Posterior Interosseous Artery Perforator Flap Phalloplasty

IntroductionThe free radial forearm (FRFA) flap is universally still considered as the gold standard technique in penile reconstruction. Typically, a considerably large flap is required, often involving almost the entire circumference of the forearm. Partial necrosis may occur at the distal-most (dorsoradial) part of the flap as a result of insufficient perfusion.AimTo describe a new technique using the posterior interosseous artery (PIOA) to supercharge FRFA phalloplasty.MethodsIn a 12-month period, all patients having FRFA flap phalloplasty were enrolled. Perioperative, after complete flap dissection, an indocyanine green perfusion scan was performed. In case of insufficient perfusion at the distalmost part of the flap, a supramicrosurgical anastomosis was performed between the FRFA pedicle and the PIOA (artery only).Main Outcome MeasuresStudied outcomes included the rate of marginal necrosis, surgical time, postoperative posterior interosseous nerve damage and urethral complications (fistula, stenosis or necrosis).ResultsA total of 27 FRFA flap phalloplasties was performed. Anastomosis of the PIOA was needed in 15 cases. No marginal necrosis was observed in these cases. There were no cases of postoperative posterior interosseous nerve damage. There were no significant differences in urethral complications (fistula, stenosis or necrosis) between the 2 groups.Clinical ImplicationsIn selected cases where insufficient perfusion of the dorsoradial part of the flap is present, patients may benefit from arterial supercharging to prevent postoperative marginal necrosis.Strength & LimitationsStrengths include a single surgeon, thus lending continuity of skill and technique, a consecutive series, and 100% short-term follow-up. Limitations include single institution series and a limited number of patients.ConclusionArterial supercharging is effective in improving perfusion of large FRFA flaps used in phalloplasty when dorsoradial hypoperfusion is detected on an indocyanine green perfusion scan. It is a technically challenging addition to the standard technique because of the small size of the vessels, the close relationship between the PIOA and the posterior interosseous nerve, and the vulnerability of the newly constructed intra-flap anastomosis.De Wolf E, Claes K, Sommeling CE, et al.
