RESUMO
This review aims to evaluate the surgical outcomes of hand-sewn esophageal anastomosis compared to mechanical anastomosis to reconstruct total gastrectomy. A systematic review and meta-analysis of comparative studies evaluating hand-sewn and stapled anastomosis were performed. A total of 12 studies were selected, comprising 1761 individuals. The results indicate that the hand-sewn and stapled esophageal anastomosis have similar surgical outcomes. Stapled anastomosis has a shorter operation time.

This review evaluated the risks and survival benefits of pancreatoduodenectomy associated with venous resection compared with palliative surgery. A systematic review with meta-analysis was performed. Higher overall survival was observed in the pancreatic resection group (HR = 4.000; 95% CI 2.800 to 5.200). However, the palliative group had fewer complications (RD = -0.170; 95% CI -0.260 to -0.070). There was no significant difference in the mortality rates (RD = 0.000; 95% CI -0.030 to 0.030). In centres with experience in pancreatic surgery, resection may be considered for locally advanced cancer and major venous invasion. Pancreaticoduodenectomy with vascular resection may improve survival for periampullary tumours compared with palliation therapy. However, pancreaticoduodenectomy with major venous resection has potentially higher morbidity than palliation therapy. Key Words: Pancreatoduodenectomy, Pancreatic neoplasms, Vascular surgical procedures.

BACKGROUND: Neuroendocrine neoplasms are extremely rare and account for 0.4% to 2% of all malignant esophageal neoplasms. The burden of the neuroendocrine histological type on the patients' prognosis and survival is poorly debated. This study aimed to compare the survival rates of primary neuroendocrine neoplasms compared with adenocarcinoma and squamous cell carcinoma of the esophagus. METHODS: This is a retrospective cohort from the Surveillance, Epidemiology, and End Results Program database. Overall survival and cancer-specific survival were evaluated with Kaplan-Meier curves and logrank tests. Proportional Cox regression models were used to evaluate variables related to overall survival. RESULTS: After eligibility criteria, 66,528 patients were selected. The mean follow-up was 22.6 months (SD 35.6). Adenocarcinoma was predominant (62%), followed by squamous cell carcinoma (36%). Large cell carcinoma, small cell carcinoma, and mixed adenoneuroendocrine carcinoma each account for less than 1% each. On the long-term overall survival analysis, esophageal adenocarcinoma showed a better prognosis than all the other histologic types (P-value for logrank test <0.001). With adenocarcinoma as a reference, HR was 1.32 for large cell carcinoma (95%CI 1.2 to 1.45) and 1.37 for small cell carcinoma (95%CI 1.23 to 1.53). The HR was 1.22 for squamous cell carcinoma (95%CI: 1.2 to 1.24); and 1.3 for adenoneuroendocrine carcinoma (95%CI 1.01 to 1.66). For multivariate Cox regression analysis, besides age and stage, the neuroendocrine subtypes large cell carcinoma and small cell carcinoma were considered independent prognostic variables. CONCLUSION: In the esophagus, large cell carcinoma and small cell carcinoma show poorer long-term survival rates than squamous cell carcinoma and adenocarcinoma.

BACKGROUND: Leiomyosarcoma is a rare malignant tumor of smooth muscle origin and represents 10-20% of all soft tissue sarcomas. Primary colon and rectal sarcomas constitute < 0.1% of all large bowel malignancies. In Li-Fraumeni syndrome, sarcomas are the second most frequent cancer (25%). Li-Fraumeni syndrome is a genetic disease with a familial predisposition to multiple malignant neoplasms. This syndrome has an autosomal dominant pattern of inheritance and high penetrance characterized by germline TP53 mutations. Patients with a history of cancer who do not meet all the "classic" criteria for Li-Fraumeni syndrome are considered to have Li-Fraumeni-like syndrome. To the best of our knowledge, this article is the first report of a patient with rectal leiomyosarcoma as the initial phenotypic manifestation of Li-Fraumeni-like syndrome. The authors also present a literature review. CASE PRESENTATION: A 67-year-old Brazilian woman underwent anterior rectosigmoidectomy and panhysterectomy secondary to rectal leiomyosarcoma. She subsequently developed carcinomatosis and died 2 years after the operation. Her family medical history consisted of a daughter who died at 32 years of age from breast cancer, a granddaughter diagnosed with adrenocortical carcinoma at 6 years of age and two siblings who died from prostate cancer. A genetic study was carried out to identify a pathogenic variant of Li-Fraumeni syndrome. In the DNA extracted from the peripheral blood leukocyte, restriction fragment length polymorphism was analyzed to search for mutations in the TP53 gene. The DNA sequencing identified the germline pathogenic variant p. R337H heterozygous in exon 10 of TP53. The patient was classified as having Li-Fraumeni-like syndrome. CONCLUSION: In patients with rectal leiomyosarcoma, it is advisable to investigate the family history of cancer and perform genetic studies to screen for Li-Fraumeni syndrome.

BACKGROUND: Vein resection pancreatoduodenectomy (VRPD) may be performed in selected pancreatic cancer patients. However, the main risks and benefits related to VRPD remain controversial. OBJECTIVE: This review aimed to evaluate the risks and survival benefits that the VRPD may add when compared with standard pancreatoduodenectomy (PD). METHODS: A systematic review and meta-analysis of studies comparing VRPD and PD were performed. RESULTS: VRPD was associated with a higher risk for postoperative mortality (risk difference: -0.01; 95% confidence interval [CI] -0.02 to -0.00) and complications (risk difference: -0.05; 95% CI -0.09 to -0.01) than PD. The length of hospital stay was not different between the groups (mean difference [MD]: -0.65; 95% CI -2.11 to 0.81). In the VRPD, the operating time was 69 minutes higher on average (MD: -69.09; 95% CI -88.4 to -49.78), with a higher blood loss rate (MD: -314.04; 95% CI -423.86 to -195.22). In the overall survival evaluation, the hazard ratio for mortality during follow-up on the group of VRPD was higher compared to the PD group (hazard ratio: 1.13; 95% CI 1.03-1.23). CONCLUSION: VRPD is associated with a higher risk of short-term complications and mortality and a lower probability of survival than PD. Knowing the risks and potential benefits of surgery can help clinicians to properly manage pancreatic cancer patients with venous invasion. The decision for surgery with major venous resection should be shared with the patients after they are informed of the risks and prognosis.

BACKGROUND: The main complication of transhiatal subtotal esophagectomy with esophagogastric reconstruction is anastomotic leak, which is responsible for a large number of postoperative deaths. It is believed that this complication is due to gastric fundus ischemia caused by the sectioning of the short gastric, left gastric, and left gastro-omental arteries. The literature, however, presents controversies. An experimental study was performed with the aim of evaluating the vascularization of the gastric fundus following sectioning of these arteries. MATERIALS AND METHODS: Forty mongrel dogs were distributed into 2 groups: a control group consisting of 15 dogs subjected to surgical simulation and an experimental group consisting of 25 dogs that underwent sectioning of these arteries. Fluorescein testing, gastric mummification, and morphometric image analysis were performed on both groups. RESULTS: In comparison with the control group, fluorescein testing on the experimental group demonstrated time-delayed fluorescence in the gastric fundus and partial coloring, (P < 0.001). Image analysis on the mummified gastric samples demonstrated significant reduction in blood vessels in the gastric fundus of the experimental group (P < 0.001). CONCLUSIONS: We conclude that sectioning of the short gastric, left gastric, and left gastro-omental arteries causes reduction in blood circulation and in the quantity of blood vessels on the anterior side of the gastric fundus of dogs.

BACKGROUND: Despite its rarity, gallbladder cancer is an aggressive type of neoplasia with a very poor prognosis. The best resection for oncological purposes continues to be right hepatectomy extended to segment IV. However, bisegmentectomy IV-V is becoming an interesting alternative because of greater preservation of the parenchyma. AIM: To report the early and late results from bisegmentectomy IV-V in cases of carcinoma of the gallbladder. METHODS: A series of seven cases of invasive carcinoma is presented (six women and one man). These patients underwent bisegmentectomy IV-V at the General Surgery Service of the Teaching Hospital of the ABC Medical School, Santo André, SP, Brazil. The study was conducted between 2002 and 2006. The patients ages ranged from 52 to 72 years. The diagnosis was preoperative (radiological) in five cases, which were all confirmed by intraoperative frozen-tissue examination, while in two cases the diagnosis was postoperative, following open cholecystectomy. RESULTS: The duration of the operation ranged from 180 to 340 minutes. The quantity of intraoperative bleeding ranged from 200 to 1500 mL. There were two major complications but no mortality. Six patients did not present any recurrence over the course of 3 to 30 months of follow-up. CONCLUSION: Bisegmentectomy IV-V may constitute a curative surgical alternative for treating gallbladder cancer. This procedure presents acceptable morbidity and mortality.

RESUMO Contexto As neoplasias neuroendócrinas são extremamente raras e representam 0,4% a 2% de todas as neoplasias malignas do esôfago. A determinação prognóstica e avaliação de sobrevida para o tipo histológico neuroendócrino é pouco debatida. Este estudo teve como objetivo comparar as taxas de sobrevida de neoplasias neuroendócrinas primárias comparadas com adenocarcinoma e carcinoma espinocelular de esôfago. Métodos Este é um estudo coorte retrospectivo do banco de dados do Surveillance, Epidemiology, and End Results Program. A sobrevida global e a sobrevida específica do câncer foram avaliadas com curvas de Kaplan-Meier e testes de logrank. Modelos de regressão de Cox proporcional foram utilizados para avaliar as variáveis relacionadas à sobrevida global. Resultados Após critérios de elegibilidade, foram selecionados 66,528 pacientes. O seguimento médio foi de 22,6 meses (DP 35,6). O adenocarcinoma foi predominante (62%), seguido pelo carcinoma espinocelular (36%). Carcinoma de grandes células, carcinoma de pequenas células e carcinoma adenoneuroendócrino misto representam menos de 1% cada. Na análise de sobrevida global, o adenocarcinoma de esôfago apresentou um prognóstico melhor do que todos os outros tipos histológicos (P valor para teste de logrank < 0,001). Com adenocarcinoma como referência, HR foi de 1,32 para carcinoma de grandes células (IC95% 1,2 a 1,45) e 1,37 para carcinoma de pequenas células (IC95% 1,23 a 1,53). O HR foi de 1,22 para carcinoma espinocelular (IC95%: 1,2 a 1,24); e 1,3 para carcinoma adenoneuroendócrino (IC95% 1,01 a 1,66). Para a análise multivariada da regressão de Cox, além da idade e do estadiamento, os subtipos neuroendócrinos carcinoma de grandes células e carcinoma de pequenas células foram considerados variáveis prognósticas independentes. Conclusão No esôfago, o carcinoma de grandes células e o carcinoma de pequenas células apresentam menores taxas de sobrevida a longo prazo do que o carcinoma espinocelular e o adenocarcinoma.
RESUMO
PURPOSE: To evaluate the incidence of fistula and stenosis of the cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach after subtotal esophagectomy. METHODS: We studied 54 patients who underwent subtotal esophagectomy, 45 (83.3%) patients with carcinoma and nine (16.6%) with advanced megaesophagus. In all cases the cervical esophagogastric anastomosis was performed with the invagination of the proximal esophageal stump inside the stomach. RESULTS: Three (5.5%) patients had a fistula at the esophagogastric anastomosis, two of whom with minimal leakage of air or saliva and with mild clinical repercussion; the third had a low output fistula that drained into the pleural space, and this patient developed empyema that showed good progress with drainage. Fibrotic stenosis of anastomosis occurred in thirteen (24%) subjects and was treated successfully with endoscopic dilatation. CONCLUSION: Cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube presented a low rate of esophagogastric fistula and stenosis, thus becoming an attractive option for the reconstruction of alimentary transit after subtotal esophagectomy.

Transhiatal Esophagectomy offers the advantage of not requiring thoracotomy or thoracoscopy. Nevertheless, it has the disadvantage of having to be performed, at least in part, with blind, blunt dissection, with high frequency of pleural lesions, increased bleeding, among other complications. The association of median diaphragm transection with partial sternotomy allows the isolation of the esophagus completely under direct vision. The authors present the technique of transhiatal esophagectomy with partial sternotomy.

INTRODUCTION: Several generic low-molecular-weight heparins (LMWHs) have recently become available worldwide, including the United States. Companies have filed for regulatory approval of generic versions in many countries, based only on compound biochemical characteristics or its immunogenicity. METHODS: Prospective study to evaluate the comparative effect of 2 enoxaparins (Sanofi-Aventis branded enoxaparin [SAe] vs eurofarma-enoxaparin [Ee], a generic version) as prophylaxis for venous thromboembolism (VTE) following major abdominal surgery. A total of 200 patients were randomized in a 1:1 ratio either to receive 40 mg of SAe or Ee subcutaneously (sc) once daily (od) postoperatively for 7 to 10 days. Compressive ultrasound was performed on day 10 + 4. RESULTS: No statistically significant differences between the 2 groups were detected. In all, 2 SAe patients presented deep vein thrombosis ([DVT] 2.1%), none of the Ee group. No major bleeding events occurred. CONCLUSIONS: This exploratory trial suggests that the generic LMWH is probably as safe and as effective as the branded enoxaparin (Lovenox, Brazil) in the prophylaxis of VTE in this population.

Although colorectal tumors are fairly common surgical conditions, 5 to 12% of these tumors are locally advanced (T4 tumors) upon diagnosis. In this particular situation, the efficacy of en bloc multivisceral resection has been proven. When right-colon cancer invades the proximal duodenum or even the pancreatic head, a challenging dilemma arises due to complexity of the curative surgical procedure. Therefore, en bloc pancreaticoduodenectomy with right hemicolectomy should be performed to obtain free margins. The present study reports three cases of locally advanced right-colon cancer invading the proximal duodenum. All of these cases underwent successful en bloc pancreaticoduodenectomy plus right hemicolectomy, with no death occurrence. Long-term survival was observed in two cases (30 and 50 months). In the third case, the patient did not present any recurrence twelve months after surgical treatment. Multivisceral resection with en bloc pancreaticoduodenectomy should be considered for patients who present acceptable risk for major surgery and no distant dissemination. This approach seems justified since the length of postoperative survival is longer in radically ressected groups (R0) than in palliativelly resected groups (R1-2).
RESUMO
AIM: To present a new technique of cervical esophagogastric anastomosis to reduce the frequency of fistula formation. METHODS: A group of 31 patients with thoracic and abdominal esophageal cancer underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube. In the region elected for anastomosis, a transverse myotomy of the esophagus was carried out around the entire circumference of the esophagus. Afterwards, a 4-cm long segment of esophagus was invaginated into the stomach and anastomosed to the anterior and the posterior walls. RESULTS: Postoperative minor complications occurred in 22 (70.9%) patients. Four (12.9%) patients had serious complications that led to death. The discharge of saliva was at a lower region, while attempting to leave the anastomosis site out of the alimentary transit. Three (9.7%) patients had fistula at the esophagogastric anastomosis, with minimal leakage of air or saliva and with mild clinical repercussions. No patients had esophagogastric fistula with intense saliva leakage from either the cervical incision or the thoracic drain. Fibrotic stenosis of anastomoses occurred in seven (22.6%) patients. All these patients obtained relief from their dysphagia with endoscopic dilatation of the anastomosis. CONCLUSION: Cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube presented a low rate of esophagogastric fistula with mild clinical repercussions.

This article reports the case of a patient with a diagnosis of diarrhea and weight loss. Subsidiary exams showed ulcerovegetant lesion in the second duodenal portion and duodenocolic fistula. An exploratory laparotomy was performed and a neoplastic lesion in the hepatic angle of the colon was observed invading the second duodenal portion. The patient then underwent a cephalic gastroduodenopancreatectomy associated with en bloc right hemicolectomy and improved well in the postoperative period. Currently, 48 months after the surgery, he does not present any signs of the disease dissemination or recurrence. The consulted literature recommends that multivisceral resection must be considered if the patient is clinically able to undergo major surgery and does not present any signs of neoplastic dissemination, since the postoperative survival time is considerably longer in the resected group and some of these patients even achieve cure.

One case of transdiafragmatic intercostal hernia after intense coughing fit followed by rib fractures in patient with history of pneumonia is presented. He had a severe coughing fit, developed a right toracoabdominal hematoma and then a tumor that was gradually enlarging. Image exams confirmed the diagnosis. Treatment consisted of surgical repair with the use of a polypropylene prosthetic mesh. It is a rare type of hernia. Only four cases were found in literature. The sooner the disease is diagnosed and treated the better the prognoses will be since it will prevent hernia from strangulation and incarceration.

A series of five cases of right-colon adenocarcinoma that invaded the proximal duodenum is presented. All patients underwent successful en-bloc pancreatoduodenectomy plus right hemicolectomy by General Surgery Service of the Teaching Hospital of the ABC Medical School, Santo André, SP, Brazil. The study was conducted between 2000 and 2007. There were two major complications but no mortality. Three patients did not present any recurrence over the course of 15 to 54 months of follow-up. Multivisceral resection with en-bloc pancreatoduodenectomy should be considered for patients who are fit for major surgery but do not present distant dissemination. Long-term survival may be attained.

OBJECTIVE: To assess the incidence of fistula and stenosis of cervical esophagogastric anastomosis with invagination of the esophageal stump into the gastric tube in esophagectomy for esophagus cancer. METHODS: Two groups of patients with thoracic and abdominal esophagus cancer undergoing esophagectomy and esophagogastroplasty were studied. Group I comprised 29 patients who underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump segment within the stomach, in the period of 1998 to 2007 while Group II was composed of 36 patients submitted to end-to-end cervical esophago-gastric anastomosis without invagination during the period of 1989 to 1997. RESULTS: In Group I, esophagogastric anastomosis by invagination presented fistula with mild clinical implications in 3 (10.3%) patients, whereas in Group II, fistulas with heavy saliva leaks were observed in 11 (30.5%) patients. The frequency of fistulas was significantly lower in Group I patients (p=0.04) than in Group II. In Group I, fibrotic stenosis of anastomoses occurred in 7 (24.1%) subjects, and 10 patients (27.7%) in Group II evolved with stenosis, while no significant difference (p=0.72) was found between the two groups. CONCLUSION: In esophagectomy for esophagus cancer, cervical esophagogastric anastomosis with invagination presented a lower rate of esophagogastric fistula versus anastomosis without invagination. Stenosis rates in esophagogastric anastomosis proved similar in both approach with or without invagination.

CONTEXT: Regional lymph node involvement in patients with malignant melanomas has been associated with poor prognosis. In-transit metastases also lead to poor long-term survival. Whereas for nodal disease only regional lymphadenectomy offers adequate locoregional control, for in-transit metastasis both local excision and isolated limb perfusion with chemotherapy plus tumor necrosis factor-alpha can be used for disease control. In cases of tumors located in the distal region of the legs, the lymphatic dissemination most commonly observed is to the inguinal chain. Consequently, therapeutic inguinal lymphadenectomy or even selective lymphadenectomy (sentinel lymph node biopsy) have been recommended. On the other hand, involvement of the popliteal chain is very rare. When this occurs, popliteal lymphadenectomy should be indicated. Local excision may be the logical approach for a few small in-transit metastases because of the low morbidity in this procedure, when compared with isolated limb perfusion. CASE REPORT: A case of melanoma of the heel with popliteal chain involvement and in-transit metastases is presented. This was treated by means of regional lymphadenectomy plus in-transit metastases excision, with a good postoperative course.

OBJETIVO: Avaliar a incidência de fístula e estenose da anastomose esofagogástrica cervical com invaginação do coto esofágico proximal no interior do estômago após esofagectomia subtotal. MÉTODOS: Foram estudados 54 pacientes submetidos à esofagectomia subtotal, 45 (83,3%) com carcinoma e nove (16,6%) com megaesôfago chagásico avançado. Em todos os casos, a anastomose esofagogástrica cervical foi realizada com invaginação do coto esofágico proximal no interior do estômago. RESULTADOS: Três (5,5%) pacientes apresentaram fístula, dois deles com saída mínima de ar e saliva pela incisão cervical que evoluíram com rápida cicatrização; o terceiro apresentou fístula de pequeno débito que drenou para o espaço pleural causando empiema que teve boa evolução após drenagem. Treze (24%) doentes apresentaram estenose fibrótica e foram tratados com sucesso com dilatação endoscópica. CONCLUSÃO: A anastomose esofagogástrica cervical com invaginação do coto esofágico proximal no interior do estômago apresentou baixa incidência de fístula e estenose tornando-se opção atraente para a reconstrução do trânsito alimentar após esofagectomia subtotal.
