The deep inferior epigastric lymphatic cable flap connected to gastroepiploic lymph node flap for treatment of refractory chylous ascites: Report of two cases.

Chylous ascites is the leakage of lipid-rich lymph into the peritoneal cavity usually due to disruption of lymphatics or increased peritoneal lymphatic pressure. Various surgical options have been proposed to treat chylous ascites but most have shown suboptimal outcomes. The gastroepiploic vascularized lymph node (GE-VLN) flap has been described previously for the treatment of lymphedema. In chylous ascites, this flap could provide an alternate drainage pathway for the intraperitoneal chylous fluid. The purpose of this report is to present another option for the microsurgical treatment of refractory chylous ascites. Herein, we report two patients with refractory chylous ascites secondary to cancer who have undergone deep inferior epigastric-based lymphatic "cable" flap (DIE-LCF) connected to a pedicle GE-VLN flap. Patients were followed-up for a minimum of 2 years. Within the first 3 months following surgery, the patient's nutritional parameters improved along with drastic reduction of ascites. At 2 years follow-up postoperative abdominal circumference decreased significantly. None required further peritoneal paracentesis and all patients were free of chylous ascites symptoms. In conclusion, the DIE-LCF connected to a pedicle GE-VLN flap could be a feasible option for the microsurgical treatment of refractory chylous ascites.

Medial sural artery as a salvage recipient vessel for complex post traumatic microvascular lower limb reconstruction.

BACKGROUND: Complex lower extremity trauma still poses a formidable challenge for micro vascular reconstruction. The extensive surrounding zone of trauma can make it difficult to find a suitable recipient pedicle for anastomosis. A need was felt for exploration of newer recipient vessels in lower extremity which could be harnessed for reliable and tension free micro anastomosis. The purpose of the present report is to highlight the possibility of using medial sural artery for safe micro vascular anastomosis in selected scenarios like vessel depleted extremity. METHODS: Between 2008 and 2013, we used the medial sural vessels for micro anastomosis in 10 cases of lower extremity trauma. All the cases had severe soft tissue trauma with or without a bony defect. A computed tomography angiogram (CTA) of the involved extremity revealed either severe perivascular scarring around the standard recipient vessels or patency of just a single vessel. However, in all cases a patent medial sural pedicle was identified on CTA. Interposition vein grafts (IVGs) were used in most cases to ensure a tension free anastomosis. RESULTS: In all cases, unscarred medial sural vessels were identified with average dissected length and diameter being 6.2 cm (range 4 to 7.5 cm) and 2 mm (range 1.5 to 2.5 mm) respectively. Vein graft [average length 5.6 cm (range 4 to 15 cm)] was interposed in seven cases, while in remaining three, long saphenous vein was used for vein anastomosis. All the flaps survived after the surgery. There was one re-exploration for evacuation of peri-anastomotic hematoma with no adverse effect on flap survival. The mean follow up period was 27.6 months. In the four cases with bone reconstruction, bony union was seen between 5 and 8 months. They were able to walk without aids and resume work after 10-14 months, following a structured rehabilitation program. The patients with soft tissue reconstruction (6 cases) could carry out aid free locomotion and resume their routine after 4-6 weeks. There were no long term complications in any of the flap. CONCLUSIONS: Medial sural artery may prove to be a reliable recipient pedicle for use in complex lower extremity trauma cases and could possibly provide a safer alternative in cases with severe perivascular scarring or in a "single vessel" extremity.

Vascularized appendicular lymph node transfer for treatment of extremity lymphedema: A case report.

Vascularized lymph node transfer has demonstrated promising results for the treatment of extremity lymphedema. In an attempt to find the ideal donor site, several vascularized lymph nodes have been described. Each has a common goal of decreasing morbidity and avoiding iatrogenic lymphedema while obtaining good clinical results. Herein, we present the preliminary clinical outcomes of an intra-abdominal lymph node flap option based on the appendicular artery and vein used for the treatment of extremity lymphedema. A 62 year-old woman with moderate lower extremity lymphedema, on chronic antibiotics because of recurrent infections and unsatisfactory outcomes after conservative treatment underwent a vascularized appendicular lymph node (VALN) transfer. At a follow-up of 6 months, the reduction rate of the limb circumference was 17.4%, 15.1%, 12.0% and 9% above the knee, below the knee, above the ankle and foot respectively. In addition, no further episodes of infection or other complications were reported after VALN transfer. Postoperative lymphoscintigraphy demonstrated that the VALN flap was able to improve the lymphatic drainage of the affected limb. According to our findings, the use of VALN transfer minimizes donor-site morbidity, avoids iatrogenic lymphedema and may provide a strong clearance of infection because of the strong immunologic properties of the appendiceal lymphatic tissue in selected patients. Despite these promising results, further research with larger number of patients and longer follow- up is needed.

The radial forearm free flap as a "vascular bridge" for secondary microsurgical head and neck reconstruction in a vessel-depleted neck.

BACKGROUND: In a vessel-depleted neck, distant recipient sites may be the only option for secondary free flap reconstruction. While interposition vein grafts and arteriovenous loops can bridge the gap between the recipient and donor pedicle, they are not without risks. In these scenarios, we examinate the reliablity of a radial forearm free flap (RFFF) as an alternative vascular conduit. PATIENTS AND METHODS: A retrospective review of cases between March 2005 and May 2016 was performed. Demographic data, prior surgical history, intraoperative details and outcomes were recorded. A total of ten patients, eight male and two female, with a mean age of 54.2 years (range, 39-74) were identified. The RFFF was initially anastomosed to either the thoracoacromial (n = 6) or internal mammary vessels (n = 4) and subsequently served as the recipient pedicle for the second "main" flap, an anterolateral thigh (n = 4), jejunum (n = 3) or fibula flap (n = 3). RESULTS: The average RFFF dimensions were 13.8 cm by 5.8 cm. All twenty flaps, ten RFFF and ten "main' flaps survived completely with only one case of minimal epidermal loss. One patient with esophageal reconstruction with jejunum developed a fistula that required closure with a local falp. At a mean follow-up of 18.4 months (range 8-29), the reconstructive goals had been achieved in all cases. CONCLUSIONS: The RFFF serves as a reliable "vascular bridge" that extends the reach of distant recipient sites to free flaps in secondary head and neck reconstruction.

The retrograde transverse cervical artery as a recipient vessel for free tissue transfer in complex head and neck reconstruction with a vessel-depleted neck.

BACKGROUND: Reconstruction in a vessel-depleted neck is challenging. The success rates can be markedly decreased because of unavailability of suitable recipient vessels. In order to obtain a reliable flow, recipient vessels away from the zone of fibrosis, radiation, or infection need to be explored. The aim of this report is to present our experience and clinical outcomes using the retrograde flow coming from the distal transverse cervical artery (TCA) as a source for arterial inflow for complex head and neck reconstruction in patients with a vessel-depleted neck. METHODS: Between July 2010 and June 2016, nine patients with a vessel-depleted neck underwent secondary head and neck reconstruction using the retrograde TCA as recipient vessel for microanastomosis. The mean age was 49.6 years (range, 36 to 68 years). All patients had previous bilateral neck dissections and all, except one, had also received radiotherapy. Indications included neck contracture release (n = 3), oral (n = 1), mandibular (n = 3) and pharyngoesophageal (n = 2) reconstruction necessitating free anterolateral thigh (n = 3) and medial sural artery (n = 1) perforator flaps, fibula (n = 3) and ileocolon (n = 2) flaps respectively. RESULTS: There was 100% flap survival rate with no re-exploration or any partial flap loss. One case of intra-operative arterial vasospasm at the anastomotic suture line was managed intra-operatively with vein graft interposition. There were no other complications or donor site morbidity during the follow-up period. CONCLUSIONS: In a vessel-depleted neck, the reverse flow of the TCA may be a reliable option for complex secondary head and neck reconstruction in selected patients.

Double gastroepiploic vascularized lymph node tranfers to middle and distal limb for the treatment of lymphedema.

BACKGROUND: Vascularized lymph node (VLN) transfer for lymphedema treatment has shown promising results. Optimal donor and recipient sites remain a matter of debate. We describe the technique and outcomes of a laparoscopically harvested extended gastroepiploic VLN flap with two levels of inset. PATIENTS AND METHODS: Between 2014 and 2015, four-patients with upper limb breast cancer-related lymphedema and three-patients with lower limb pelvic cancer-related lymphedema who underwent VLN transfers were included. After harvest, the gastroepiploic VLN flap was divided into two halves that were separately inset at the level of elbow and wrist (upper limb) or knee and ankle (lower limb). The mean patient age was 53.1 years (range, 42-65 years). RESULTS: The average flap size after division was 6.3 cm in length (range, 5-7 cm) and 3.4 cm in width (range, 3-4 cm). The mean pedicle length was 3.2 cm (range, 2.5-4 cm). All flaps survived completely. No donor or recepient site complication was noted. At a mean follow-up of 9.7 months (range, 8-11 months), the mean circumference reduction rate was 43.7 ± 2.5% along the entire limb (P < 0.05). No episode of infection was noted postoperatively. CONCLUSIONS: Double gastroepiploic VLN transfers to middle and distal limb are a safe approach with very promising results. This technique may be used to improve clinical outcomes by enhancing the lymphatic drainage of the entire affected limb in a uniform fashion. In addition, the laparoscopic harvest can provide decreased donor site morbidity with a faster recovery.

A head-to-head comparison among donor site morbidity after vascularized lymph node transfer: Pearls and pitfalls of a 6-year single center experience.

Between 2010 and 2016, 110 patients with extremity lymphedema underwent vascularized lymph node (VLN) transfer: groin (G-VLN = 20), supraclavicular (SC-VLN = 54), and right gastroepiploic (RGE-VLN = 36) open and laparoscopic approach. Herein, we discuss the pearls and pitfalls for VLN harvest and compare donor site morbidity and complications. Lymphatic leakage: G-VLN (n = 1) and SC-VLN (n = 1) and one hematoma: SC-VLN were found. Laparoscopic harvest of the RGE-VLN reduces donor site morbidity. However, surgeons experience is imperative to minimize donor site morbidity and complications. J. Surg.

Successful microsurgical replantation of an amputated penis.

Penile amputation is an uncommon injury for which immediate surgical replantation is warranted. Microsurgical replantation is the "standard" method for penile replantation. Early replantation yields a high success and low complication rate. We report a case of a 34-year-old male who presented with amputation at the proximal penile shaft which was successfully replanted using microsurgical techniques. Minor skin necrosis was noted post-operatively which was debrided and covered with skin graft. Follow-up at 6 months showed satisfactory cosmetic appearance, normal voiding, return of sensations and erectile function. The level of evidence was V.

Gall bladder Adenocarcinoma in a Young Girl.

A 16-year-old girl presented with abdominal discomfort, weakness, and jaundice. General examination revealed deep icterus with hard lymph nodes in left supraclavicular region. On gastrointestinal examination, we appreciated a hard intra-abdominal lump in the right hypochondrium. Biochemical evaluation showed features of obstructive jaundice. Imaging confirmed the presence of gall bladder lump with multiple intra-abdominal lymph nodes. Fine needle aspiration cytology of neck nodes demonstrated metastatic adenocarcinoma. Fine needle aspiration cytology of the gall bladder lump (done under sonographic guidance) confirmed poorly differentiated adenocarcinoma. To the best of our knowledge, malignancy of the gall bladder has not been reported in individuals less than 18 years in India, and only three cases have been reported worldwide in English literature.
