A Tailored Approach for Recurrent Groin Hernias

PURPOSE: Recurrent groin hernias are a significant problem with high recurrence rates. There is a great deal of controversy regarding their management. This study examined the outcome of patients who had undergone a repair of recurrent groin hernias. METHODS: This study examined retrospectively the medical records of all patients who underwent repairs of recurrent groin hernias (a total 239 cases) between January 1998 and December 2006. The repair was tailored to the previous operation and the patients' medical condition. The types of previous operations, present operation, complications and re-recurrence rate were analyzed. RESULTS: Of the 2,542 groin hernias operated on, 239 cases (9.4%) were treated for recurrent groin hernias. The types of previous surgery were conventional open tissue repair in 199 cases (83.3%), Lichtenstein repair in 28 cases (11.7%), open mesh repair (PHS, Perfix plug) in 6 cases (2.5%) and laparoscopic repair in 6 cases (2.5%). The recurrent groin hernias were repaired using a laparoscopic method in 123 cases (51.4%), open mesh repair in 92 cases (38.4%), Lichtenstein repair in 18 cases (7.5%) and a conventional open tissue repair in 6 cases (2.5%). Postoperative complications occurred in 40 cases (16.7%), which included 10 seromas, 4 wound infections, 3 hematomas, 2 wound swellings, 8 scrotal swelling, 5 dysurias, 2 chronic neuralgias. There were 6 cases of re-recurrence in the 239 cases of recurrent groin hernias (2.5%). CONCLUSION: A tailored approach based on the previous repair and the medical condition of the patients with recurrent groin hernias is associated with a decrease in the incidence of major postoperative complications and a low recurrence rate (2.5%).

The Impact of Obesity on Operative Results and Postoperative Courses in Laparoscopic-assisted Distal Gastrectomy (LADG)

PURPOSE: Despite known advantages of laparoscopy-assisted distal gastrectomy (LADG) over open surgery, including less blood loss, less pain, faster recovery, and shorter hospital stays, many surgeons still hesitate to perform LADG in overweight patients due to concerns about increased perioperative morbidity. We investigated whether surgical outcomes in LADG differ in overweight patients and normal patients, as well as the influence of surgical experience. METHODS: Between April 2004 and December 2006, 331 consecutive patients underwent LADG for preoperatively diagnosed early gastric cancer. Using the definition of overweight by western criteria, patients were classified into a low (n = 187, BMI 25 kg/m(2)) group. We retrospectively analyzed surgical outcomes, including operation time, retrieved lymph nodes, hospital courses, and postoperative complications. RESULTS: The only differences in overweight and normal patients were longer operation time, incision length, and fewer retrieved lymph nodes. As our surgical team accumulated experience (after 250 cases in our study), there were no differences at all between the two groups. CONCLUSION: Technical difficulty in overweight patients could hamper some surgical outcomes but didn't worsen the post- operative courses or complications. Moreover, those difficulties can be overcome as the surgical team accumulates experience.

Comparison of Reconstruction Methods after Distal Gastrectomy for Gastric Carcinoma in Terms of the Long Term Physiologic Function and Nutritional Status; Billroth I Gastroduodenostomy versus Roux-en Y Gastrojejunostomy

PURPOSE: The only curative treatment for gastric carcinoma is surgery and it is still under debate which reconstruction method is better after performing gastrectomy for gastric carcinoma. The typical reconstruction methods after distal gastrectomy are Billroth I, Billroth II and Roux-en Y reconstruction. Yet it is difficult to compare these methods and not so much is known about which reconstruction is better in terms of the physiologic and nutritional function. With this background, we compared two reconstruction methods after distal gastrectomy (Billroth I versus Roux-en Y reconstruction) in terms of the long term physiologic function and nutritional status to create a reference for selecting reconstruction methods after distal gastrectomy. MATERIALS AND METHODS: Between 1999 and 2002, 663 patients who underwent distal gastrectomy for early gastric carcinoma filled out questionnaires every six months after operation, and these questionnaires evaluated the physiologic function. To evaluate their nutritional status, blood tests were performed every six months to check their albumin, protein and hemoglobin levels, and we checked the body weight every 6 months as well. RESULTS: The total score of the 15 questions on the questionnaire concerned with the physiologic function showed no difference between the two groups at every evaluation time, and both groups showed very low total scores, indicating tolerable physiologic function after operation. When comparing each question between two the groups, only symptoms of regurgitation and food passage showed a difference between the two groups, showing that the Roux-en Y group had better function in terms of these two symptoms. The Billroth I group showed a better nutrition status, indicating that the level of albumin, protein and hemoglobin were higher in the Billroth I group, with statistical significance. Body weight loss was severe in the Roux-en Y group. CONCLUSION: The physiologic function is slightly better in the Roux-en Y group in terms of some symptoms such as regurgitation and food passage. However, the nutritional status is better in the Billroth I group. In conclusion, because we cannot definitely ascertain which reconstruction is better when we consider both the physiologic and nutritional functions, it is reasonable that surgeon should choose reconstruction methods according to their experience and preference.

Comparative Analysis of Laparoscopy-assisted Gastrectomy versus Open Gastrectomy

PURPOSE: There has been increased the number of early gastric cancer and laparoscopy-assisted gastrectomy (LAG), due to early detection through mass screening program. We started the LAG in April 2004 and performed 119 cases of gastric cancer in 2005, so we report a surgical outcome compared with that of open gastrectomy (OG). MATERIALS AND METHODS: 119 patients underwent LAG in 2005, and for open group, 126 patiens of early gastric cancer were selected sequentially from January 2005 to March 2005. We compared clinicopathologic characteristics, postoperative courses and complications between two groups. RESULTS: There was no significant difference between age, a length of hospital stay, distal resection margin and a number of retrived lymph nodes. The operation time was longer in LAG group (239.2 vs 123.3 mins, P < 0.001) and a diet progression was faster in LAG group (first flatus: 3.05 vs 3.70 days, SOW: 2.86 vs 3.22 days, liquid diet: 3.87 vs 4.19 days ,soft diet: 4.84 vs 5.26 days, P < 0.001). But there was no difference statistically in postoperative discharge date (7.73 vs 8.25 days, P=0.229). The additional requirement of analgesic injection was less frequent in LAG group (2.97 vs 4.92 times, P < 0.001). The harvested lymph nodes were similar in both groups (23.9 vs 23.1, P=0.563). A complication rate was lower in LAG group (4.9% vs 9.5%), but there was no statistical significance (P=0.179). There was no mortality in both groups and no conversion to open gastrectomy in the LAG group. CONCLUSION: LAG can be performed safely and accepted in view of curative procedure in treatment of early gastric cancer. But we need the follow up of long-term period to evaluate the survival rate and recurrence, and a prospective randomized controlled study should be done to establish that LAG will be a standard operation for early gastric cancer.

Indication of Dissection of the 14v Lymph Node in Advanced Distal Gastric Cancer

PURPOSE: According to the 2nd English Edition of the Japanese Gastric Cancer Association (JGCA) in 1998, in case of distal gastric cancer, the 14v (superior mesenteric vein) lymph node (LN) is included in the N2 group. However, in Korea, a modified radical gastrectomy is performed, and a 14v LN dissection is not done as a routine procedure. Thus, we investigated the rate of metastatic 14v LNs, evaluated the necessity of dissection of the 14v LN, and searched for indications of 14v LN dissection. MATERIALS AND METHODS: From April 2004 to August 2005, we enrolled the patients who were diagnosed as having advanced gastric cancer in the distal third portion of the stomach. We performed a distal gastrectomy with D2 lymph node dissection as defined in the 2nd English edition of the JGCA classification. We calculated the positive rate of metastatic LNs of each station and analyzed the relationship between the positive rates of No.6 LNs and 14v LNs. We also compared the positive 14v LN group with the negative 14v LN group. RESULTS: The total number of patients was 50, the mean age was 56 (range 30~80) years, and sex ratio (Male/Female) was 1.63 : 1. In 47 (94%) cases, distal a gastrectomy with gastroduodenostomy was done, and in the remaining 3 (6%) cases, a distal gastrectomy with gastrojejunostomy was done. The most frequently metastatic LNs were nos. 3 and 6 (54%). The metastatic rate of the 14v LN was 10%, which was similar to that of LN no. 9. In the comparison of the 14v positive group with the 14v negative group, there were significant differences in the numbers of metastatic LNs (mean 25.4 vs 4.91, P<0.001) and the numbers of metastatic no. 6 LNs, (mean 6.8 vs 1.42, P<0.001), and if no. 6 LNs were metastatic, the possibility of metastasis to the 14v LN was 19.2%. In the 14v positive group, all cases were more than stage 3 by the UICC 6th edition. CONCLUSION: In cases of advanced cancer with metastasis to the no. 6 LN, there was a good chance of metastasis to the 14v LN. Thus, in the operative field, if the tumor is advanced to more than stage 3 by the UICC classification and the no. 6 LN is metastatic, a 14v LN dissection is necessary. However, the usefulness of a 14v LN dissection should be evaluated prospectively through an analysis of tumor recurrence and long-term survival.

Treatment Strategy of Gastric Cancer in Patients Older than 80 Years of Age

PURPOSE: The geriatric population will continue to increase in the coming decades, and the number of gastric cancer patients who are over 80 years of age is increasing. The aim of this study was to suggest optimal treatment in these patients on the basis of the cause of death. METHODS: Forty-four patients who underwent curative resection in the course of gastric cancer treatment and were over 80 years of age at Asan Medical Center between January 1990 and February 2002 were included in this study. The cause of death of those patients was retrospectively analyzed by checking medical record or calling to relatives. RESULTS: Average age of 41 patients was 81.41 years old and follow up duration was 49 months. Until February 2004, overall mortality was 23 patients (56%). The mortality from gastric cancer-related and from other disease was 12 patients (52%) & 11 patients (48%), respectively. The most common cause of death from other disease was senility. Median survival time of 11 patients from cancer none-related death was 57 months. Median survival time of 32 patients corresponding stage l & ll was 52.5 months. CONCLUSION: We, therefore, conclude that a standard gastrectomy is basically appropriate for patients older than 80 years of age, as long as they demonstrate a good risk.

Clinical Analysis of 61 Krukenberg Tumors

PURPOSE: A Krukenberg tumor is an ovarian tumor of a signet-ring cell type. This tumor arises more commonly in young women, and the prognosis is poor. The primary focus of this tumor is often found at gastrointestinal malignancy, especially gastric cancer. We tried to identify the clinical characteristics of this tumor, and in that regard, this report might be helpful. MATERIALS AND METHODS: We reviewed the 61 patients with Krukenberg tumors, who had been diagnosed at our hospital from 1994 to 2002, and retrospectively analyzed the clinical features. RESULTS: The age distribution ranged from 15 to 59 years, and the mean age was 41 years. The most common symptom was a lower abdominal mass (46%). Fourty-two cases (77%) showed bilateral ovarian involvement, and the size of this tumor was variable, but in 24 cases (44%) the size was 5~0 cm for the largest diameter. Among 54 cases, 40 cases had ascites, and the volume of ascites was variable. The median survival of the 61 patients was 10 months, and Krukenberg tumor developed 19.7 months after the primary operation. The median survival durations of recurrence patterns were 20 months for the Krukenberg tumor alone, and 7 months for the Krukenberg tumor with peritoneal seeding. CONCLUSION: In young women treated with a gastrectomy, especially one for an advanced tumor, closed observation with abdominal ultrasonography or computed tomography to detect a Krukenberg tumor is recommended. The patient with a Krukenberg tumor alone has a better prognosis than one with a Krukenberg tumor combined peritoneal seeding. We will have to consider more progressive treatment for the patient with a Krukenberg tumor alone.

Cause of Death after Kidney Transplantation / 대한이식학회지

PURPOSE: Over the several decades, there has been a considerable improvement in the survival of patients who undergo renal transplantation due to newer immunosuppressive agents and development of surgical technique and post-operative management. However, life expectancy beyond 10 years is still considerably less than that in the general population. We studied the causes of patient death after kidney transplantation to determine the major causes of death, to decrease the mortality rate of patient and to increase the graft survival rate. METHODS: From Jan. 1990 to Dec. 2002, 1353 renal transplantation were performed at Asan Medical Center. There had been 63 cases of patient death and we reviewed the causes of death, recipient-donor relationship, immunosuppressive agents, history of rejection and the time of death after transplantation in these patients, retrospectively. RESULTS: The major causes of patient death were infection (36.5%), cardiovascular disease (14.3%), malignancy (9.5%), hepatic failure (11.1%), miscellaneous (11.1%) and unknown (22.2%). Thirty-nine (61%) of total death occurred in the first year of transplantation and major cause in first year of transplants was infection (46.2%). Of 63 deaths, 35(55.6%) were with graft function and 49 (77.8%) had history of rejection. The patients with brain- death donor had a higher death rate than that of the patients with living donors (3.7% vs 7.8%, P=0.002). The patients who had history of rejection have higher death rate than the patient with no history of rejection (22.6% vs 1.3%, P<0.001). CONCLUSION: Active efforts for the prevention of rejection and infection in early phase of transplantation and close surveillance of malignancy and cardiovascular disease in long-term follow up will decrease the death of transplanted patients and increase the graft survival rate.
