Objective: The aim of this study was to describe the clinical and pathological characteristics and surgical outcomes of a series of patients with STS. Material and methods: The clinical records of 2403 undergoing surgery between October 2014 and April 2018 were retrospectively reviewed. Twenty-two patients (0.91%) presented STS. Results: Mean age was 52 years (range: 19-92) and 13 (59%) were women. The tumors were located in the lower extremities in 12 cases, head and neck in five, trunk in three and upper extremities in two. Fourteen cases (63.6%) were high-grade tumors. Pleomorphic sarcoma was the most common histologic type (32%) followed by synovial sarcoma (18%), liposarcoma (14%), and other types (36%). All the tumors were completely resected and five patients (35.7%) required amputation, four in the lower extremity and on in the upper extremity. Different reconstructive procedures were performed accor- ding to tumor size and location, including three free flaps. Those patients with high-grade sarcomas or with positive margins received postoperative radiotherapy. After a mean follow-up of 16 months, six patients presented local recurrences and four patients had synchronous metastatic disease in the lungs; all these patients had high-grade tumors. Overall survival was 86.4%. Conclusion: STS are rare and invasive neoplasms, widely distributed, requiring aggressive and occa- sionally complex surgical procedures. It is necessary to consider adjuvant treatments in selected cases and to maintain regular follow-up due to the high rate of recurrences and distant metastases.","PeriodicalId":78597,"journal":{"name":"Revista argentina de cirugia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45955617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results: The procedure was successful in all the patients and mean operative time was 210 minutes (IQR: 170-240). There were no complications and were discharged on postoperative day 4 (IQR: 3-5). All the surgical specimens had negative margins and lymph node count was > 12 lymph nodes. All the patients are alive and free from disease at 7, 5, 4 and 2 months of follow-up.

Objective: The aim of our study is to describe the epidemiological variables of gallbladder cancer at our centre and to compare them with data from the worldwide literature. Material and methods: Patients undergoing cholecystectomy between January 1, 2006, and December 31, 2015. The following variables were analyzed: sex, age, male to female ratio, reason for cholecystectomy, urgent or scheduled. In case of gallbladder cancer, sex, age, histopathology, cell differentiation, gallbladder layer invasion, lymphovascular, cystic lymph node, adjacent tissues and liver invasion; and cancer staging according to Nevin staging system and the Union for International Cancer Control (UICC). Results: Ninety-two gallbladder neoplasms were found, representing 1.26% of all cholecystectomies. Mean age of patients with gallbladder cancer was 57.9 years (range, 22-88 years) of whom 69.5% (n=64) were women, with the same female to men ratio of 2:1 described for cholecystectomy. The histopathology of the 92 gallbladder cancers corresponded to adenocarcinoma, 93.4% (n= 86); squamous cell carcinoma, 4.4% (n= 4); and undifferentiated malignancy with elements of epithelial and mesenchymal origin, 2.2% (n= 2). There were two cases of adenocarcinoma with squamous metaplasia, two mucinous carcinomas, one papillary adenocarcinoma and one case of antral-type and intestinal metaplasia. Sixty tumors (65.4%) were moderately differentiated; 12 (13%) well differentiated; 11 (11.9%) poorly differentiated; and 4 (4.3%) were undifferentiated. In 5 cases (5.4%) the type of differentiation was not described. Conclusion: In gallbladder cancer diagnosed after a cholecystectomy, it is more frequent in the female sex, with adenocarcinoma being the most common histological type. Interestingly, the number of young patients with gallbladder cancer is noteworthy.","PeriodicalId":78597,"journal":{"name":"Revista argentina de cirugia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44564377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The aim of our study is to analyze the adverse events of minimally invasive esophagectomy in prone position during the learning curve. Material and methods: Between November 2011 and June 2017, 36 patients underwent minimally invasive esophagectomy in prone position in the Hospital Interzonal General de Agudos (HIGA) San Martín and the Instituto de Diagnóstico de La Plata. Results: During the abdominal stage one patient presented coronary vessel injury. The complications occurring in the thoracic stage included lung injury (n =2), azygos arch injury (n = 1), thoracic duct dissection (n = 1), laryngeal recurrent nerve lesion (n = 1) and main stem bronchus injury (n = 1) during lymph node resection. Most of these complications occurred in the first 20 patients, while in the remaining 16 cases only lung injury occurred (p = 0.10) Conclusion: Minimally invasive esophagectomy in prone position is a feasible and safe procedure that can cause serious intraoperative complications due to its complexity. Although the results of our series did not show statistically significant differences, the number of adverse events during surgeries performed by the same team showed an important reduction associated with better training.","PeriodicalId":78597,"journal":{"name":"Revista argentina de cirugia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41561478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The anatomical proximity of the midface to the orbit, base of the skull and maxillary sinuses is a challenge for the surgeon who must perform a curative resection. Objective: The aim of this presentation is to report the survival rate and disease-free interval in T4a and T4b neoplasms of the palate and paranasal sinuses consecutively resected over a 30-year period. Material and methods: Surgery was extended to the orbit in 85.2%, the skull in 8.3%, the neck in 18.7% and the parotid gland in 7.3%. Soft tissue reconstruction was performed using free flaps in 32.5%, muscle flaps in 21.6%, local flaps in 20.2%, musculocutaneous flaps in 14.7% and skin flaps in 11.3%. Results: Local and general complications were reported, and 4/203 patients (2%) died. At 5 years, overall survival was 62.5% and disease-free survival was 53%. Univariate analysis revealed that lack of previous treatment was significantly associated with recurrence and squamous cell carcinoma was a predictor of survival. Conclusions: The indication of exenteration is mandatory in the presence of ophthalmoplegia or involvement of the orbital content. Survival at 5 years is acceptable, considering the advanced stages of the disease.
