Surgical feed ligation performed in 22 year old female with scalp arteriovenous malformation

Scalp arteriovenous malformation (AVM) are rare conditions that usually need surgical treatment. Its management is difficult because of its high shunt flow, complex vascular anatomy, and possible cosmetic complication. The etiology of scalp AVM may be spontaneous or traumatic. This vascular lesion present as scalp lump or a mass, grotesque, pulsatile mass with a propensity to massive haemorrhage. Various treatment option that have been adopted to treat these lesions include surgical excision, ligation of feeding vessel, trans arterial and transvenous embolization, injection of sclerosant into the nidus and electro thrombosis. A 22-years-old-female referred to cardiothoracic division with a 10 years history of a large fronto-parietal pulsatile reddish soft mass, progressively increasing in size, measuring about 15x6x2 cm, ulcerated area; without any symptoms and history of trauma. Three-dimensional CT angiography demonstrated a mass that was completely within the scalp and prominent vascular that was completely within the scalp and was not associated with bone or periosteum. The feeding arteries were originated from angular artery, supratrochlear artery, left and right superficial temporal artery. Surgical excision and ligation of feeding vessel was performed without complication. With pre-operative appropriate surgical planning, scalp AVM can be excised safely without any major complication. Though some cases may be treated with percutaneous or endovascular embolization, surgery remains the treatment of choice. In the event of scalp ulceration and haemorrhage, total excision is the only option.

Initial experience of laparoscopic right hemicolectomy with complete mesocolic excision in Singapore: a case series

INTRODUCTION@#Laparoscopic colorectal surgery is increasingly performed worldwide due to its multiple advantages over traditional open surgery. In the surgical treatment of right-sided colonic tumours, the latest technique is laparoscopic right hemicolectomy with complete mesocolic excision (lapCME), which aims to lower the rate of local recurrence and maximise survival as compared to standard laparoscopic right hemicolectomy (lapS).@*METHODS@#We conducted a retrospective analysis of our initial experience with lapCME in Singapore General Hospital between 2012 and 2015. All procedures were performed by a single surgeon.@*RESULTS@#Nine patients underwent lapCME and 16 patients underwent lapS. Indication for lapCME was cancer in the right colon. None of the patients required conversion to open surgery, and all were discharged well. The number of lymph nodes resected in the lapCME group was significantly greater than in the lapS group (29 ± 15 vs. 19 ± 6; p = 0.02) during the study period, and the mean operation time was significantly longer for lapCME (237 ± 50 minutes vs. 156 ± 46 minutes; p = 0.0005). There were no statistically significant differences in terms of demographics, tumour stage, time taken for bowel to open postoperatively, time taken for patient to resume a solid diet postoperatively and length of hospital stay. Two patients who underwent lapS were re-admitted for intra-abdominal collections - one patient required radiology-guided drainage, while the other patient was managed conservatively.@*CONCLUSION@#Our initial experience with lapCME confirms the feasibility and safety of the procedure.
