Topical hemostasis in laparoscopic surgery.

A major goal during any surgical intervention is minimization of blood loss, which reduces the need for blood transfusion. In open surgery, the possibility for the surgeon to use the hands directly in contact with the bleeding tissues for hemostasis, makes mechanical methods, such as compression, ligatures or sutures, important to achieve proper hemostasis. In laparoscopic surgery, where the intervention is performed by means of small incisions through which the surgeon's hand cannot directly achieve the tissues, the problem of hemostasis is critical and needs more attention. Either in open or in laparoscopic surgery, significant bleeding during surgery is controlled through vessel ligation, suturing, and electrocautery. Topical hemostatic agents are useful adjuncts to surgical hemostasis for controlling non-specific bleeding. The introduction of different devices and topical agents has made possible to perform more complex interventions also in laparoscopy. The Authors discuss about the type, the field of application, the side effects of the hemostatic devices and of the topical hemostatic agents.

Surgical reconstructive procedures for treatment of ischial, sacral and trochanteric pressure ulcers.

BACKGROUND: Pressure ulcers are frequent complications for long term hospitalized bed-ridden patients which are not able to move or move very little. In fact, the lesion forms in a skin and muscle region which undergoes a constant pressure between an underlying bone protrusion and a support structure such as a bed or a wheelchair. Initially only the outer layers are involved but in time, the ulcer can spread to the deeper structures and reach the bone. PATIENTS AND METHODS: In our work we described the anatomical areas that are most often subject to developing a pressure ulcer and we considered the surgical treatment and reconstructive procedures which are applied using a logical and rigorous sequence. RESULTS: We considered 4 clinical cases (2 ischiatic sores, 1 sacral sore and 1 gluteal-trochanteric sore) which demonstrate the surgical treatment and the reconstructive procedures. CONCLUSIONS: It is crucial to cover the defects with a thick flap to give more support and protection to the areas which undergo pressure and to lower the incidence of recurrences.

Subcutaneous cervical emphysema and pneumomediastinum due to a diastatic rupture of the cecum.

Pneumomediastinum usually occurs after esophageal or chest trauma. Subcutaneous cervical emphysema as a presentation of non-traumatic colonic perforation following colorectal cancer or diverticulitis, is very rare. We report a case of a patient with rectal cancer who developed a diastatic cecum retroperitoneal perforation with a secondary pneumomediastinum and cervical emphysema. The patient was in treatment with a neoadjuvant chemo-radiotherapy for a low rectal cancer. Treatment consisted in an emergency right hemi-colectomy with ileostomy and performance of distal colonic fistula. The Authors discuss the occurrence of pneumomediastinum and cervical emphysema complicating rectal cancer, pointing out ethiopathogenesis, clinical presentation, diagnosis and treatment. The importance of performing a diverting colostomy when neoadjuvant chemotherapy is scheduled in patients with stenotic rectal cancer, although not clinically occluded.

Laparoscopic treatment of mucinous adenocarcinoma of jejunum associated with celiac disease. Case report.

Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

Revascularisation through the obturator foramen of lower limbs with a compromised ipsilateral groin due to infection.

INTRODUCTION: Infra-inguinal vascular reconstruction with active groin infection is a concerning issue. Using resistant grafts to infection is the most adopted approach. However, in absence of these materials in acute situations, the trans-obturator approach allows for limb revascularisation avoiding the infected site. We evaluated the effectiveness of this approach in patients who needed lower limb revascularisation with an ipsilateral groin infection. MATERIALS AND METHODS: A retrospective study was conducted over a four-year period. RESULTS: Over this period, 13 patients underwent trans-obturator reconstructions (13 external iliac-popliteal above-knee and one aortobipopliteal above-knee bypass). Seven patients had been previously revascularised and were admitted for graft infection (six infra-inguinal bypasses, one axillo-bifemoral bypass). Four presented with acute limb ischaemia, three with groin haematoma and one with a groin abscess. The remaining cases consisted of drug-addicted patients with injury of femoral vessels due to self-injection of drugs. The patients underwent reconstructions with autologous grafts which complicated early with groin haematoma. After transobturator revascularisation, the groin underwent debridement with applying vacuum-assisted wound closure device. CONCLUSION: The transobturator approach could be considered as a chance for lower limb revascularisation in case of ipsilateral groin infection. Moreover, avoiding the infected site allowed us to focus separately and safely on the treatment of the inguinal wound.
