1.Routine Intraoperative Forced-Air Warmer Usage in Prevention of Perioperative Hypothermia: To Use or Not to Use in Daycare Breast Lumpectomy?
Journal of Surgical Academia 2015;5(1):34-43
Intraoperative active warming in daycare surgery may be least popular compared to major elective surgeries due to
the lesser risk of perioperative hypothermia. This prospective, single blind, randomized, controlled trial in daycare
breast lumpectomy was done to evaluate the routine use of intraoperative forced-air warmer in the presence of other
warming modalities in prevention of perioperative hypothermia. Fifty patients were randomized into two groups;
Group 1 received forced-air warmer and Group 2 received a standard cotton thermal blanket. Both groups received
circulating-water mattress. Intraoperatively, all patients received pre-warmed intravenous fluid with an in-line
warmer. Ear and ambient temperature was recorded using infrared ear thermometer and digital thermo-hygrometer
respectively. Measurement was done before induction, every 15 minutes intraoperatively, upon arrival in recovery
room and 30 mins later, postoperatively. All patients were normothermic prior to induction of anaesthesia. During
the initial half an hour post-induction, both groups mean core temperature decreased at approximately 0.5˚C. Both
showed no statistical difference in mean core temperature (0.04 ˚C) within the initial half an hour. The next half an
hour, both groups had approximately 0.2˚C decrement but this time, Group 2 had a slightly higher mean core
temperature than Group 1 which maintained until the end of surgery. Overall, within the initial one hour postinduction
of GA, there was a drop of 0.7˚C and 0.6°C in Group 1 and Group 2 respectively, however the difference
in final mean core temperature between the two groups was 0.05°C and it was not statistically significant (p value <
0.05). None of the patients experienced intraoperative hypothermia (< 36˚C) and all remained in the normothermic
range with no shivering or sense of feeling cold, postoperatively. The results of the present study found no
significant difference in the changes of final core temperature with or without the usage of intraoperative forced-air
warmer in the presence of other warming measures in daycare breast lumpectomy.

PURPOSE: Pleomorphic adenoma is the most common benign neoplasm in parotid gland. Superficial parotidectomy was usually used to remove the pleomorphic adenoma. But, this method has to remove tumor with normal parotid tissue. Authors did lumpectomy to remove pleomorphic adenoma in parotid gland, because pleomorphic adenoma is wrapped in a capsule as it grows. The purpose of this study is to evaluate the efficacy of lumpectomy as a treatment of pleomorphic adenoma in parotid gland. METHODS: From 2002 to 2008, 8 patients underwent the lumpectomy of the pleomorphic adenoma in parotid gland. Occurrence of the complications and recurrance were evaluated. RESULTS: Patients were followed-up for a mean 45 months. There were no recurrance or no complication after lumpectomy. CONCLUSION: Authors suggest that the lumpectomy lead to decrese complications, recurrane and can be used as a procedure for the resection of pleomorphic adenoma in parotid gland.

PURPOSE: The residual microscopic carcinoma after breast conserving surgery is the most important risk factor of local recurrence. As local recurrences usually develop around resected margins, it is ge nerally accepted that every effort should be made to achieve negative margins intraoperatively, and the presence of microscopically positive margins requires reexcision. Interestingly, sizable percentage of reexcisions results in a specimen free of residual tumor, and may not contribute to disease control, but do add morbidity, cost, and possibly compromise cosmetic result. The goal of our study was to identify which clinico-pathologic factors were associated with positive resection margin, and to identify the variables associated with no residual carcinoma on reexcision or total mastectomy specimens. METHODS: From Sepember 1994 to July 1999, 322 breast conserving surgery were performed on breast cancer patients at the Department of General Surgery, Samsung Medical Center. Among them, 13 patients had positive surgical margins and were treated with reexcision (reexcising the previous lumpectomy cavity with a margin of 1-2 cm of normal tissue) or total mastectomy. RESULTS: The factors associated with positive resection margins were large tumor size, the presence of extensive intraductal component (EIC), and suspicious mammographic microcalcifications without mass density. Six (46.3%) of these reoperation cases for positive margins were negative for residual tumor. The factors correlating with no residual carcinoma on reexcision or mastectomy specimens were small histologic primary tumor size and only one positive resection margin rather than 2 or more positive margins. CONCLUSION: The patients with above-mentioned factors associated with positive resection margins should be treated with more wide local excision or total mastectomy to avoid a second surgical procedure. If the patients with only one positive margin and small tumor size refuse second operation, they could be treated with irradiation only sparing an additional surgical procedure.

PURPOSE: Rotter's nodes are removed in the course of a radical mastectomy, however they are not routinely removed in a modified radical mastectomy and breast conserving surgery, although they can be. Having been relatively ignored, the prognostic value and correlation of Rotter's nodes with axillary nodal status have rarely been reported or systematically studied. The aims of the present study were to assess the frequency and pattern of Rotter's node metastasis in breast cancer patients, and to compare the incidence of axillary lymph node metastasis and Rotter's node. We also investigated the rate of skip metastasis. METHODS: In order to investigate the predictability of axillary node positivity, we compared the status of axillary lymph nodes and the pathological prognostic markers. In 580 consecutive mastectomies performed for breast carcinomas between 1987 and 1999, axillary and Rotter's nodes were routinely dissected and separately sampled during mastectomy. RESULTS: The mean number of axillary lymph nodes and Rotter's nodes were 19.5 and 0.9. Axillary lymph nodes metastases were found in 47.2% of all patients. The frequency of axillary lymph node metastasis and the involvement of a higher level of axillary lymph node were significantly increased with increasing tumor size. However, metastasis at Rotter's nodes did not follow this pattern. Rotter's nodes were anatomically present in 39.8% of patients and an average of 2.3 lymph nodes was found in the interpectoral region. Rotter's metastases were found in 5% of all patients, and 10.6% of those with axillary lymph node metastases. The number of Rotter's nodes metastases was higher as the metastases were found at a higher level (p<0.05). CONCLUSION: The presence of axillary metastases was related to histologic grade, nuclear grade and lymphovascular invasion, but was not related to the mitotic index or perineural invasion. It is apparent that the potential risks from Rotter's and skip metastases were not great in all patients, although the routine excision of Rotter's nodes should be applied to patients with more locally advanced disease (T2-3, N1-N2).

PURPOSE: Surgical axillary dissection to determine the status of nodes remains as a part of the standard operation in the management of breast cancer. Rotter's nodes are removed in the course of a radical mastectomy but they are not routinely removed in a modified radical mastectomy and breast conserving surgery, although they can be. Having been relatively ignored, the prognostic value and correlation of Rotter's nodes with axillary nodal status have been rarely reported or systematically studied. The aim of the present study was to access the frequency and pattern of Rotter's node metastasis in breast cancer patients, and compare the incidence of axillary lymph node metastasis and Rotter's node. We also investigated the rate of skip metastasis. MATERIALS AND METHODS: To investigate the predicting axillary node positivity, we compared the status of axillary lymph node and pathological prognostic markers. In 580 consecutive mastectomy performed for breast carcinomas between 1987 to 1999, axillary and Rotter's node were routinely dissected and separately sampled during mastectomy . RESULTS: The mean number of axillary lymph node and Rotter's nodes were 19.5 and 0.9. Axillary lymph nodes metastases were found in 47.2% of all patients. Frequency of axillary lymph node metastasis and involvement of higher level of axillary lymph node were significantly increased by increasing tumor size.

Rotter's metastases were found in 5% of all patients, and 10.6% of those with axillary lymph nodes metastases. Number of Rotter's nodes metastases were higher as the metastases were found to higher level(P<0.05). CONCLUSION: The presence of axillary metastases were related to histologic grade, nuclear grade and lymphovascular invasion, but not related to mitotic index and perineural invasion. In summary, number of axillary lymph node and metastatic rate of axillary lymph nodes were similar to western reports. It is apparent that potential risk from Rotter's and skip metastases were not great in all patients, but routine excision of Rotter's nodes should be applied to patients with more locally advanced disease.

PURPOSE: The purpose of the study is to determine the mammographic and ultrasonographic features of the breasts with partial mastectomy and irradiation. MATERIALS AND METHODS: The authors reviewed the serial studies of 23 patients who had partial mastectomy and irradiation. Mammogram and ultrasonogram were perfomed every 6 months after surgery in all patients. Sixteen of 23 patients took mammogram and ultrasonogram 1 month after surgery additionally. We evaluated skin thickening, edema, new calclfication, and postoperative scar. RESULTS: Skin thickening was observed in all patients at initial study after surgery and were most pronounced 6 months after surgery. In the most of patients, increased breast density suggesting edema was seen at the initial study after surgery. Skin thickening and edema were most pronounced 6 months who had retumed to normal state 18 months after surgery in 3 of 5 patients who had serial studies until 18 months after surgery. Scars were noted in 20 of 23 patients and 9 of 20 patients had scars 6 months after surgery. The postoperative changes including skin thickening, edema, and scar were most pronounced at 6 months after surgery and had retumed to normal at 18 months after surgery. CONCLUSION: We conclude that postoperative imaging should be obtained 6 months after surgery, followed by every 6 month intervals, which can be effective in differentiating postoperative scar from recurrent carcinoma and can avoid invasive studies.

Laparoscopic liver resection has been widely accepted nowadays for selective cases of liver diseases. Laparoscopic left lateral sectionectomy and minor LLR are considered standard practice worldwide and cautious introduction of major laparoscopic liver resections like hemihepatectomies, central sectionectomy etc.. in institutions having experienced liver surgeons. Because of increasing young liver donor, laparoscopic donor hepatectomy is becoming popular, which gives better cosmetic outcomes. Many clinical trials compared laparoscopic liver resection safety, long term outcomes with open procedures. More recently, advances in laparoscopic instruments and techniques encouraged Korean surgeons to choose a laparoscopic procedure as one of the treatment options for benign or malignant diseases of liver.

Simple liver cysts are common and benign lesions, and most of them are detected by ultrasonography (US) or computed tomography (CT) during a medical checkup. Because simple liver cysts are generally asymptomatic, they do not require treatment, although hemorrhage, infection or rupture may occur in rare cases and these cases must receive proper treatment. The diagnosis of simple liver cysts is usually easy because of their typical morphological findings on US or CT. However, when a liver cyst contains hemorrhage or it is inflamed on imaging studies, it is sometimes difficult to differentiate simple hepatic cysts from such conditions as cystadenoma and cystadenocarcinoma. In this report, we describe a case of simple liver cyst that was complicated by intracystic hemorrhage, and this malady was initially diagnosed as biliary cystadenocarcinoma. We successfully treated this lesion by left lateral segmentectomy.
