OBJECTIVE:: To evaluate the technical feasibility, effectiveness, and safety of robot-assisted gastrectomy (RAG) with lymphadenectomy, using the da Vinci system through analyses of our initial series of 100 consecutive patients. SUMMARY BACKGROUND DATA:: The application of robotic surgery was proven to be one of the best cutting-edge technologies for successful minimally invasive surgery by providing solutions to the many drawbacks of laparoscopic surgery, yet few reports have studied robotic surgery in gastric cancer. METHODS:: A review of a prospectively designed database at our institute from July 2005 to October 2007 revealed a series of 100 consecutive RAG patients with a preoperative diagnosis of early gastric cancer. Clinicopathologic characteristics and surgical outcomes were analyzed. RESULTS:: All operations were performed successfully without open or laparoscopic conversion. There were 33 total gastrectomies and 67 subtotal gastrectomies with D1+&bgr; or extended lymphadenectomy (D2). The mean total operation time and console time were 231 and 150 minutes, respectively. There were 13 postoperative morbidities and 1 postoperative mortality. The first flatus was noted on postoperative day 2.9, soft diet was started on postoperative day 4.2, and the mean postoperative hospital stay was 7.8 days. Although all patients were diagnosed as early gastric cancer preoperatively, the final pathology report revealed that 19 patients exhibited a depth deeper than T2. The mean number of retrieved lymph nodes was 36.7 (range, 11–83). None of the specimens showed microscopic tumor involvement in the resection line. CONCLUSIONS:: This study demonstrated that RAG with lymphadenectomy can be applied safely and effectively for patients with gastric cancer.

<P>The treatment of choice for remnant gastric cancer is resection by open conventional method, but due to adhesion and deformed anatomic structure, reoperation is one of the most complicated surgeries. We therefore introduce 2 cases of laparoscopy-assisted completion total gastrectomy. One was 67 yrs old male who had radical subtotal gastrectomy with gastrojejunostomy due to stomach cancer 30 years ago. Gastric polyp was found in routine EGD. Biopsy results showed focal adenocarcinoma and laparoscopy-assisted total gastrectomy with Roux-en-Y esophagojejunostomy was decided and performed. The other case was 65 yrs old male who went through radical subtotal gastrectomy with gastroduodenostomy 8 years ago due to stomach cancer. Recur was diagnosed by routine EGD, and laparoscopic assisted total gastrectomy with Roux-en-Y esophagojejunostomy was done. As can be seen in this study, laparoscopy-assisted gastrectomy could be safely applied in remnant gastric cancer.</P>
Case Reports : Trochanteric Stress Fracture in a Female Window Cleaner
( Bong Jin Lee ),( Jyewon Song ) 대한고관절학회 2016 Hip and Pelvis Vol.28 No.1
Stress fractures may occur at various sites in the femur including the head, neck, shaft, supracondylar and condylar regions. To the best of our knowledge, stress fracture occurring in the trochanteric region has not been previously reported. We report here a case of trochanteric stress fracture in a 53-year-old female window cleaner treated with hip nailing without adverse consequences. Careful consideration of this entity is needed when evaluating patients who have repetitive jumping up and down.

<P>BACKGROUND/AIMS: The prognosis of hepatic metastasis from gastric carcinoma is dismal. A few patients are candidates for hepatic resection. The present study analyzed the oncologic outcomes of hepatic resection performed in metachronous hepatic metastasis from gastric cancer. METHODOLOGY: Between January 1986 and November 2007, 14 patients underwent hepatectomy for metachronous hepatic metastasis secondary to gastric adenocarcinoma. Clinicopathological data were reviewed retrospectively. RESULTS: The median interval between gastrectomy and hepatectomy was 12.9 months. The numbers of hepatic lesions were single in 9 patients, more than two in 5 patients. The overall survival rates following hepatectomy were 67.0% at 1 year, 38.3% at 3 year. The disease progression occurred in 10 patients in the remaining liver. CONCLUSION: Surgical resection could be a treatment option for the hepatic metastasis from gastric cancer. The comparison of efficacy between surgical resection and the other treatment modalities will be required.</P>

<P>Abstract</P><P>Background and Aim: </P><P>The prevalence of being overweight has risen remarkably in Korea. This study sought to clarify the relationship between being overweight and surgical outcomes in gastric cancer patients.</P><P>Methods: </P><P>A total of 410 patients who underwent curative total gastrectomies with D2 dissection from January 2000 to December 2003 were retrospectively studied from a prospectively designed database. The patients were assigned to two groups based upon their body mass index (BMI): non-overweight, BMI < 25 kg/m<SUP>2</SUP>; overweight, BMI ≥ 25 kg/m<SUP>2</SUP>. Perioperative surgical outcomes, postoperative morbidity, mortality, recurrence, and prognosis were analyzed.</P><P>Results: </P><P>The overweight group had longer operation time and more postoperative complications than the non-overweight group. The two groups were similar in terms of transfusion volumes, postoperative bowel movement, time to initiation of a soft diet, and postoperative hospital stay. Patterns of recurrence and cumulative survival rates were similar for each group. Multivariate analysis showed that being overweight was not a risk factor for recurrence or poor prognosis.</P><P>Conclusion: </P><P>Although being overweight was associated with increased operation time and higher risk of complications in gastric cancer patients undergoing curative total gastrectomy, it had no effect on recurrence or long-term survival.</P>

<B>Background</B><P>The aim of this study was to investigate the effects of D2 lymphadenectomy with spleen preservation on surgical outcomes in locally advanced proximal gastric cancer.</P><B>Methods</B><P>Between January 2000 and December 2004, a total of 366 patients who underwent curative total gastrectomy were studied retrospectively from a prospectively designed database.</P><B>Results</B><P>The spleen-preservation group experienced shorter operation times, a lower incidence of perioperative transfusion, and shorter postoperative hospital stays. Perioperative transfusion and splenectomy were independent risk factors for morbidity. There was no significant difference between the two groups in recurrence or cumulative survival rate when adjusted according to cancer stage. Multivariate analysis showed that tumor size, serosal invasion, and nodal metastasis were independent prognostic factors, while splenectomy was not. The cumulative survival rate in pN0-status patients was significantly higher in the spleen-preservation group, while there was no significant difference in the survival of pN1- or pN2-status patients between the two groups.</P><B>Conclusions</B><P>Splenectomy for lymph node dissection in proximal gastric cancer patients obviously showed poor short-surgical outcomes, but it did not affect long-term outcomes in terms of recurrence and overall survival rate. Therefore, spleen-preserving lymphadenectomy is a feasible method for radical surgery in locally advanced proximal gastric cancer. J. Surg. Oncol. 2009;99:275–280. © 2009 Wiley-Liss, Inc.</P>
