"Big Incision, Big Surgeon !!" At the beginning of surgery, excellence was associated with big incisions and rapidity of the operation because of the anesthesia. But, nowadays there has been a big change after the development of laparoscopic surgery. It is not a discipline unto itself, but more a philosophy of surgery, a way of thinking. " Small Incision, Best Surgeon!!" So-called Minimally invasive surgery (MIS) is a means of performing major operations through small incisions, often using miniaturized, high-tech imaging systems, to minimize the trauma of surgical exposure. Laparoscopic cholecystectomy became the stepping stone of the present status of MIS and is opening the dawn of the least invasive and eventually to non-invasive surgery, for exemple, Natural Orifice Transluminal Endoscopic Surgery (NOTES). I review the history of laparoscopic cholecystectomy cholecystectomy and introduce what procedures the surgeons are performing in the field of hepatopancreato biliary diseases.

Kimura's disease is a rare benign disease characterized by subcutaneous or dermal tumors occurring predominantly on the head and the neck. It usually occurs in young adults without constitutional symptoms, except for peripheral blood eosinophilia. The histopathologic features of the tumor are characterized by dense lymphoid aggregates containing a prominent germinal center and by the proliferation of endothelial cells associated with varying degrees of lymphocytic, histiocytic, and eosinophilic infiltration. We report a case of Kimura's disease without peripheral blood eosinophilia in a 24-year-old male who had had a painless and slowly growing tumor-like swelling on his right groin for one year. The mass was excised, and the specimen was confirmed as Kimura's disease. After surgical excision, the lesion recurred, so 30 mg of oral prednisone was given daily for one month and then decreased gradually for another one month. Now, the lesion is completely healed.

Pancreatic heterotopia and adenomyoma are variants of the same process. Pancreatic heterotopia is characterized by the presence of pancreatic acinar, islet, and/or ductular elements, usually associated with smooth muscle proliferation, outside the topographic boundaries of the pancreas. Adenomyoma differs from pancreatic heterotopia in that acinar and islet-like tissue are not present. The common sites are stomach, duodenum, and jejunum, but ectopic pancreatic tissue may also be encountered in Meckel's diverticulum, the ampulla of Vater, gallbladder, umbilicus, fallopian tube, and mediastinum. Most examples are encountered incidentally during surgery, and on rare occasions, epigastric pain, weight loss, hemorrhage, gastric outlet obstruction, and intussusception have been attributable directly to the presence of the heterotopic pancreas. But intestinal obstruction of small bowel by pancreatic adenomyoma has not been reported as of yet. The authors have experienced one case of intestinal obstruction by pancreatic adenomyoma requiring operation in a 28-year-old female. We found the 3-fold distened proximal jejunal loop, about 1 meter length, and abrupted narrowed point, and a normal sized distal loop. We treated this case by performing longitudinal incision and transverse suture of the narrowed point, so that the diameter of narrowed point was enlarged. At that time we found the 0.7Cm sized intraluminal mass at the narrowed point. We concluded that intestinal obstruction in this case was made by contraction of circular muscle due to pancreatic adenomyoma, not by a mass effect.

PURPOSE: The laparoscopic adrenalectomy (LA) has become the preferred procedure for adrenal tumors since it has many advantages; a more rapid and comfortable recovery, shorted hospitalization, and fewer complications. The purpose of this study was to report the initial 4 years experiences of LA and describe the unusual findings encountered during the operations. METHODS: From February 1997 to November 2000, a total of 20 LA were performed. Several techniques of LA have been described already. We prefer the transabdominal approach in the lateral decubitus position using 3 or 4 trocars. RESULTS: 20 patients had all unilateral tumor. The pathological findings were 11 aldosteronomas, 6 Cushing adenomas, 2 pheochromocytomas and 1 cortical carcinoma. 18 cases of 20 patients were successfully operated by laparoscopic procedure and 2 cases were converted to open adrenalectomy. The reasons of conversion were sudden cardiac arrest due to unknown origin and intraoperative bleeding due to periadrenal massive fat. During the laparoscopic operation, 2 patients showed abnormal EKG findings. The pathologies of those patients were non-catecholamine-secreting cortical adenomas. After operation, they have been completely normal in EKG. The average operating time for the complete laparoscopic adrenalectomies was 186 minutes in the first 9 cases and 132 minutes in the next 9 cases. The first oral intake was started within 24 hours in all cases. There was no postoperative complication and no operative morbidity or mortality. The average hospital stay was 6.2 days in the first 9 cases and 4.2 days in the next 9 cases. CONCLUSION: The LA is relatively fast and safe method and is accepted as the preferred procedure for the adrenal tumors but it should be well prepared perioperatively. Surgeons and anesthesiologists should be aware of those possible cardiovascular complications and of the problems inherent in the manipulation of the adrenal gland during LA.

BACKGROUND: Pancreaticoduodenectomy is well established in the armamentarium of the surgeon treating periampullary carcinoma and benign lesion. With refinement of operative technique and more enlighting management during the postoperative period, the morbidity and mortality of this procedure have reduced significantly. Leakage of the pancreaticojejunal anastomosis has been a major complication after this procedure, frequently reported in an incidence of 5 percent to 15 percent. Therefore, authors retrospectivly reviewed about clinical experience of duct-to-mucosa anastomosis and PTBD in pancreaticoduodenectomy. OBJECTS & METHODS: The authors retrospectively reviewed the medical records of 93 patients who had undergone a pancreaticoduodenectomy with the duct-to-mucosa method between 1994 and 2000 by one surgeon. RESULTS: The male-to female ratio was 2.1:1(63:30) and mean age was 57 years old(range from 26 to 77). Thirty patients(32.6%) of 93 patients were distal common bile duct cancer, 22 patients(24%) were pancreatic head cancer, 21 patients(23%) were Ampulla of Vater cancer, 5 patients(5.4%) were chronic pancreatitis, 3 patient(3.3%) were duodenal cancer. The operative morbidity was 35.8%, and there was three perioperative mortality(3.2%). The mean operative time was 8.8 hours. A pancreatic fistula was diagnosed in 6 of the 93 patients(6.5%) and surgical intervention was done in 1 of the 6 patients. A PTBD for preoperatively biliary drainage was done 64 cases and complication related PTBD was 3 cases(4.7%, hemobilia). CONCLUSIONS: Even if this anastomotic technique requires a little more time and attention by the surgeon, we experienced that the low incidence of pancreatico-jejunal anastomosis related complication represents a validation of the method, and a motivation to adapt this anastomotic technique. But, this method is not absolute because surgeon's preference is most important factor in operation.

Acinar cell carcinoma (ACC) of the pancreas is a rare malignancy making up approximately 1% of pancreatic non-endocrine malignant tumors. The common finding on computed tomography is a solitary, well-defined, heterogenous hypodense mass with enhancing capsule. ACC is a highly cellular tumor with minimal stroma and a lack of stromal desmoplasia. The accurate diagnosis of ACC cannot typically be done by histology alone but rather requires immunohistochemical staining or electron microscopy for the identification of pancreatic enzymes and zymogen granules. ACC has been considered a cancer with a poor prognosis due to frequent metastasis, a high recurrence rate, and low respectability. Surgical resection is the treatment of choice that can lead to long-term survival. ACC has a better prognosis than ductal carcinoma of the pancreas, but a worse prognosis compared to islet cell carcinoma. We report two cases of ACC with 5-year survival after surgical resection.

BACKGROUND/AIMS: The diagnosis and treatment of benign hepatic lesions remain controversal. The widespread availability of ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI), and their frequent application in evaluating abdominal pain, has resulted in more frequent discovery of incidental benign hepatic lesions. To address these points, the clinical data of patients with benign hepatic lesions treated with surgical resections at our hospital were reviewed retrospectively. METHODS: We reviewed the clinical records of thirty nine patients with benign hepatic lesions who had undergone hepatic resection from January, 1985 to August, 2002 at Hanyang University Hospital. RESULTS: There were 39 patients, whose mean age was 47.0 years. The ages ranged from 24~74 years. There were 14 male patients and 25 female patients. The ratio of male and female was 1:1.8. Major symptoms were right upper quadrant pain, mass, epigastric pain, and non-specific GI symptoms. 22 cases of anatomical resections (10 right lobectomy, 5 left lobectomy, 7 left lateral segmentectomy) and 17 non anatomical resections were done. There were no postoperative deaths in this series. Fourteen patients (35.9%) developed operative complications. All of them were minor complications. During the mean follow up time, symptomatic relief was achieved in patients out of patients who we could contact with opd follow up or telephone interview. Three patients died of massive pleural effusion 4 years after operation, myocardial infarction 14 months after operation, alcoholic liver cirrhosis and diabetes mellitus 33 months after operation. CONCLUSION: Hepatic resection in patients who had benign hepatic lesions in the liver was safe and effective treatment modality if patients were selected with suitable indications.

BACKGROUND/AIMS: Acinar cell carcinoma (ACC) of the pancreas is a rare malignancy. ACC has been considered a cancer with poor prognosis due to frequent metastasis, a high recurrence rate, and low resectability. The aim of this study was to examine the clinical, radiologic and pathologic features of ACC in Korean patients, and surgical outcome was also investigated. METHODS: We reviewed the clinical records of two patients with ACC who had undergone operation in January 1996 and December 2005 at Hanyang University Medical Center. Through searching of medical journal from 1983 to 2009, 27 patients reported on literatures as Korean ACC patients were reviewed together. The clinical, pathohistologic, and radiologic features, treatment, and prognosis were investigated for all 29 patients. RESULTS: ACC was more common in male, and age at diagnosis ranged from 25 to 68 years (median 54). Symptoms were, mostly abdominal pain and mass. Liver was most common organ of metastasis at diagnosis and recurrence after operation. The mean tumor size was 7.0 cm, and most common location was tail. Of the 29 patients, 22 underwent surgical resection. Excluding 7 cases of not-reported survival, the median survival with operation was 22.4 months compared to 1.5 months with non-operation. CONCLUSIONS: In Korea, the clinical features of ACC include young age, large size, tail location, and nonspecific tumor markers. Surgery should be actively performed in the treatment of ACC regardless of size.

PURPOSE: Multiple primary cancers are not a rare disease. The clinicopathologic characteristics of a hepatocellular carcinoma with extrahepatic malignancies, have not been identified. To address these points, the clinical data of patients with a hepatocellular carcinoma, with extrahepatic malignancies, treated with surgical resections at our hospital, were retrospectively reviewed. METHODS: We reviewed the clinical records of ten hepatocellular carcinoma patients, with extrahepatic malignancies, who had undergone an operation between January, 1986 and December, 2002 at the Hanyang University Hospital. RESULTS: 10 patients were comprised of 9 males and 1 female, with a mean age of 58.6 years, ranging from 34 to 75. There were 9 stomach cancers and 1 rectal cancer extrahepatic malignancies associated with the hepatocellular carcinomas. Four of these were synchronous type and six were metachronous type. The treatments used for the HCCs were: 1 extended right lobectomy, 6 right lobectomies, 1 each of a TAE with RFTA, a segmentectomy with RFTA, and a segmentectomy. The operations for the extrahepatic malignancies included 1 low anterior resection, for the rectal cancer and 9 subtotal gastrectomies, for the stomach cancers. During the mean follow up time of 66.1 months, five patients survived and five died. CONCLUSION: Patients who have a hepatocellular carcinoma, associated with extrahepatic malignancies, have been treated with aggressive operations and combination therapies. Stomach cancer is the most common extrahepatic malignancy associated with a hepatocellular carcinoma.
