Thoracoscopic segmentectomy: one vessel may hide a second one.

We report the case of an asymptomatic neonate prenatally diagnosed with a left basal pulmonary sequestration. The preoperative chest computed tomography with contrast showed 2 aberrant arteries arising from the distal thoracic aorta and supplying the intralobar left inferior lung malformation. Strategy and treatment by thoracoscopic segmentectomy are presented.

Segmentectomia Pulmonar Anatómica por Videotoracoscopia: Experiência Inicial de um Centro

The use of minimally invasive surgery for the treatment of lung cancer has been growing worldwide. Between May 2008 and November 2012, we performed 24 videothoracoscopic anatomical lung resections in our department. This includes 22 lobectomies and 2 anatomic segmentectomies, which is known to be a more complex surgery, since it demands a finer dissection of sub-lobar structures. We report the clinical cases of two patients who underwent anatomic segmentectomies. The first one was a 63 year old woman, smoker and with a history of breast cancer 20 years earlier. An incidental 9 mm node was found in the lingula. The patient underwent an anatomic lingulectomy and the frozen section was suggestive of a primary lung cancer. Therefore, we proceeded to a full lymphadenectomy. The final pathology evaluation showed a typical carcinoid tumour (pT1aN0). The second patient was a 50 year old woman, a smoker and with a heavy family history of lung cancer. In a screening CT scan a 8 mm ground glass opacity was identified in the left lower lobe (segment VI). After a VATS wedge resection of the node the frozen section evaluation was compatible with adenocarcinoma. We then proceeded to an anatomic segmentectomy with lymphadenectomy. The definitive pathology evaluation confirmed that it was a pT1a N0 bronchioloalveolar adenocarcinoma. The patients now have 5 and 2 months of follow up respectivelly and neither of them has signs of recurrence and the surgical incision showed a good aesthetic result. Anatomic segmentectomy is the indicated surgery especially in patients with low grade tumours, in early stage lung cancers or in patients without pulmonary function for a lobar resection, and it can be done safely using VATS.

Hepatectomia regrada por videolaparoscopia

With the improvement of laparoscopic techniques, endoscopic liver surgery has become feasible. While laparoscopic wedge liver resection are performed more frequently, laparoscopic (anatomical or nonanatomical) liver resection are still at an early stage of development and are somewhat controversial. We reporte laparoscopic hepatic resection without use of sophisticated laparoscopic instruments. A 47-year-old woman underwent radical mastectomy for adenocarcinoma in 1995. 1n the postoperative follow-up presented, a lesion in the left hepatic lobe and, after laparoscopic approach, left lateral segmentectomy was performed. The hepatic resection elapsed without complications. The surgical time was 4 hours and the blood loss was minimal, without transfusion being necessary.The abdominal drain was removed in 24 hours and the patient was discharged in the second postoperative day. Compared to the classic approach by laparotomy, this method was less traumatic, required a shorter hospital stay, and followed by faster recovery.

Trauma abdominal penetrante consecutivo à corrente elétrica industrial

The authors present a case report of a victim of high power electric shock. The main electric lesion was a penetrating abdominal wound with loss of substance of the abdominal wall and an electric lesion of the hepatic segment and of the gallbladder. The surgical treatment included hepatic segmentectomy, cholecystectomy, repair of the abdominal wall with Marlex prosthesis and skin graft, besides the debridment of the lesions of extremities. The postoperative evolution was satisfactory and the follow-up for 6 months didn't show any sequelae.

Ressecção isolada do segmento I sob exclusão vascular hepática total

An isolated hepatic caudate lobectomy was performed in a fifty-seven-year-old white woman presenting a colo-rectal metastasis to hepatic segment I. The resection was performed under total liver vascular exclusion due to the proximity to hepatic veins. The patient presented an uneventful hospitalization being discharged on day seven.

Hiperplasia nodular focal múltipla do fígado: subtipo misto hiperplásico/adenomatoso

Focal Nodular Hyperplasia is a benign lesion of the liver, which usually presents with one or two localizations. We report the uncommon case of a 51-year-old female who presents with right upper quadrant pain that worsened in the previous month, without association with feeding. Four hepatic lesions were evidenced at Computerized tomography, the largest being of 8 cm in diameter, of atypical behavior. She was submitted to hepatic segmentectomy of the segment III. The pathologic diagnosis returned focal nodular hyperplasia mixed hyperplastic and adenomatous sub-type. The patient had a good postoperative evolution and is in ambulatory follow-up.

Video assisted resections. Increasing access to minimally invasive liver surgery?

Objective: To evaluate perioperative outcomes, safety and feasibility of video-assisted resection for primary and secondary liver lesions. Methods : From a prospective database, we analyzed the perioperative results (up to 90 days) of 25 consecutive patients undergoing video-assisted resections in the period between June 2007 and June 2013. Results : The mean age was 53.4 years (23-73) and 16 (64%) patients were female. Of the total, 84% were suffering from malignant diseases. We performed 33 resections (1 to 4 nodules per patient). The procedures performed were non-anatomical resections (n = 26), segmentectomy (n = 1), 2/3 bisegmentectomy (n = 1), 6/7 bisegmentectomy (n = 1), left hepatectomy (n = 2) and right hepatectomy (n = 2). The procedures contemplated postero-superior segments in 66.7%, requiring multiple or larger resections. The average operating time was 226 minutes (80-420), and anesthesia time, 360 minutes (200-630). The average size of resected nodes was 3.2 cm (0.8 to 10) and the surgical margins were free in all the analyzed specimens. Eight percent of patients needed blood transfusion and no case was converted to open surgery. The length of stay was 6.5 days (3-16). Postoperative complications occurred in 20% of patients, with no perioperative mortality. Conclusion : The video-assisted liver resection is feasible and safe and should be part of the liver surgeon armamentarium for resection of primary and secondary liver lesions.

Congenital cystic adenomatoid malformation of the lung: indications and timing of surgery

We review a single surgeon and surgical centre's experience with congenital cystic adenomatoid malformation of the lung (CCAML) in relation to clinical spectrum, operative experience, and postoperative course. A retrospective hospital record review was done on surgically treated cases of CCAML over a 10-year period, focusing on number with antenatal diagnosis, spectrum of postnatal presentation, type of surgery performed, and outcome. Forty-seven patients from birth to 14 years of age underwent surgery for CCAML. Antenatal diagnosis (ante) was made in 30 cases. Of these, 10 became symptomatic before surgery. Six of the 17 postnatally-diagnosed (pnd) cases were an asymptomatic incidental finding. Overall, 16 were symptomatic in the 1st year of life, and five were symptomatic beyond 1 year of age. Symptoms varied from respiratory distress (seven ante, six pnd) to chronic cough (three, and recurrent chest infection (three ante, two pnd). All preoperative diagnoses were confirmed with chest CT. Most patients (25) were operated on before 3 months of age. Eleven were operated on in the first 2 weeks of life as emergency surgery for respiratory distress. The most common lobe involved was the right upper lobe (16), and lobectomy was performed in 42 cases, segmentectomy in four, and pneumonectomy in one. Seventeen cases were extubated immediately postoperatively; 29 required postoperative ventilation overnight, and nine needed more prolonged ventilation. Early postoperative complications included pneumothorax (two), pleural effusion (one), and chylous effusion (one). Late complications included recurrence in three cases (all segmentectomy), who then subsequently underwent lobectomy. There was one death from respiratory failure. Because there is an increasing trend in the detection of asymptomatic antenatally-diagnosed CCAML, consideration of early surgical excision to prevent complications is suggested by our series. CT scanning is mandatory for postnatal evaluation because chest x-ray could be normal. Safe elective excision after 3 months is supported by our low morbidity and less need for postoperative ventilation. Lobectomy is the procedure of choice to prevent recurrence.
