Abstract
BACKGROUND Advances in medicine and changes in the medical environment can affect the diagnosis and treatment of diseases. The main purpose of the present study was to investigate whether the difference in accessibility to diagnosis and treatment facilities influenced the occurrence of appendectomy in Korea. METHODS We collected data on 183,531 appendectomy patients between 2003 and 2017 using the National Health Insurance Services claims. Retrospective analysis of relationship between the age-standardized rate (ASR) of appendectomy and clinical variables affecting medical accessibility was performed. Pearson's correlation analyses were used. RESULTS The incidence of appendectomy decreased from 30,164 cases in 2003 to 7,355 cases in 2017. The rate of computerized tomography (CT) scans for diagnosis of appendicitis increased from 4.73% in 2003 to 86.96% in 2017. The ASR of appendectomy in uncomplicated and complicated appendicitis decreased from 48.71 in 2005 to 13.40 in 2010 and 8.37 in 2005 to 2.96 in 2009, respectively. The ASR of appendectomy was higher in the high-income group. The proportion and ASR of appendectomy in older age group increased steadily with years. The total admission days continued to decrease from 6.02 days in 2003 to 4.96 days in 2017. CONCLUSION The incidence of appendectomy was seemingly associated with the rate of CT scan. In particular, the incidence of appendectomy in uncomplicated appendicitis was markedly reduced. Through enhanced accessibility to CT scans, accurate diagnosis and treatment of appendicitis can be facilitated.

Parkinsonism Relat Disord 2021; 83:15-21. [PMID: 33454604 DOI: 10.1016/j.parkreldis.2020.12.026] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 11/23/2020] [Accepted: 12/17/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Previous evidence has suggested roles for α-synuclein propagation and vitamin B12 (VitB12) deficiency in the pathogenesis of Parkinson's disease (PD). We investigated whether gastric cancer (GC) patients who underwent gastrectomy had a lower risk of PD and whether VitB12 supplementation modified the risk. METHODS GC patients aged ≥50 years who underwent curative gastrectomy between 2007 and 2012 (n = 72,216) and matched comparison groups (n = 211,389) were identified from the Korean National Health Insurance database. The risks of PD were analyzed by Cox regression. RESULTS Compared to their matched comparison groups, GC patients who underwent gastrectomy showed a decreased risk of PD (adjusted HR [aHR] 0.86; 95% confidence interval [CI] 0.75-0.98), but the significance disappeared after further adjustment with smoking and body mass index (BMI). To elaborate, subtotal gastrectomy (STG) was associated with decreased risk of PD (aHR 0.85; 95% CI 0.74-0.99) while total gastrectomy (TG) was not (aHR 0.89; 95% CI 0.66-1.19), although the risk reduction was not significant when further adjusted for smoking and BMI. Among the patients who underwent TG, their risk of PD was markedly lower when they had VitB12 supplementation after surgery (aHR 0.36; 95% CI 0.17-0.76), while the risk was higher when they did not have any (aHR 1.55; 95% CI 1.03-2.32). CONCLUSIONS GC patients who underwent gastrectomy and received uninterrupted VitB12 supplementation had a decreased incidence of PD. This study provides indirect epidemiological evidence for the potential roles of gastrectomy and VitB12 in the pathogenesis of PD.

Ann Surg Treat Res 2020; 100:18-24. [PMID: 33457393 PMCID: PMC7791190 DOI: 10.4174/astr.2021.100.1.18] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 10/19/2020] [Accepted: 10/19/2020] [Indexed: 12/15/2022] Open
Abstract
Purpose Many studies have demonstrated that single-incision or reduced-port laparoscopic distal gastrectomy is a feasible method compared to conventional laparoscopic distal gastrectomy. Using rigid-type laparoscope and right-side approach, we could perform dual-port laparoscopic distal gastrectomy (DPLDG) for gastric cancer. This study aimed to compare the surgical outcomes of DPLDG to those of 3-port laparoscopic distal gastrectomy (TPLDG). Methods From March 2017 to December 2019, this retrospective study included 218 patients with gastric cancer who underwent DPLDG (106 patients) or TPLDG (112 patients) at SMG-SNU Boramae Medical Center. Surgical outcomes were compared between 2 operation methods. Results Operation time was similar between DPLDG and TPLDG (158.9 ± 33.4 minutes vs. 154.0 ± 31.1 min, P = 0.787). The number of retrieved lymph nodes was similar between the 2 groups (35.3 ± 14.6 vs. 37.0 ± 13.5, P = 0.415). The complication rate in DPLDG and TPLDG groups was 10.4% and 8.9%, respectively (P = 0.894). The time to first flatus, time to first diet, and postoperative hospital stay were similar between the 2 groups. There were no reoperation or mortality cases. The cost of trocars was 359.9 US dollars (USD) in DPLDG and 291–391.4 USD in TPLDG. Conclusion The surgical outcomes of DPLDG and TPLDG did not differ. Regarding fewer incisions, DPLDG can be an alternative option for TPLDG.

Abstract
Purpose Accumulated evidence indicates laparoscopic surgery (LS) has the advantages of less wound pain, less blood loss, shorter hospitalization, and faster functional recovery than open surgery (OS). Previous studies have analyzed the advantages of LS based on hospital data. This study is the first to compare surgical outcomes and health economic data using nationwide administrative claims datasets for gastric cancer. Methods The claims datasets of the Health Insurance Review and Assessment Service for patients that underwent gastrectomy from May 2012 to April 2017 were analyzed. A total of 76,445 cases (LS, 42,395 and OS, 34,050) were included. Postoperative complications and medical costs were included in the analysis. Results We analyzed 76,445 cases of gastrectomy. Analysis showed LS was associated with fewer surgical wound infections (2,114 [6.21%] vs. 1,057 [2.49%], P < 0.001), minor abdominal infections and abscesses (826 [2.43%] vs. 390 [0.92%], P < 0.001), cases of surgery-related peritonitis (50 [0.15%] vs. 31 [0.07%], P = 0.0019), repair surgeries (28 [0.08%] vs. 3 [0.01%], P < 0.001), reoperations (504 [1.48%] vs. 343 [0.81%], P < 0.001), less antibiotic use (1,717 [5.04%] vs. 1,268 [2.99%], P < 0.001), and shorter hospital stays (13.61 days vs. 9.97 days, P < 0.001). However, average medical cost was 510,734 Korean Won (444 US dollar) higher for LS than OS. Conclusion The study confirms the clinical benefits of LS over OS for gastrectomy in terms of fewer postoperative complications and shorter hospital stays. However, the average medical cost of LS was higher than that of OS.

Abstract
Gastric cancer patients represent a rather divergent patient group and in certain carefully selected cases of early forms of gastric cancer the D2 gastrectomy could be considered a more radical procedure than the biological and oncological characteristics of the primary tumor on the gastric wall would require. As any unnecessary dissection increases morbidity without always respective survival benefits, an approach that could accurately predict and actually dictate the exact extent of lymph node dissection would be ideal. It is more than logical the assumption that the standard D2 lymphadenectomy could represent an overtreatment in distinct patients groups such as patients with early gastric cancer with favorable pathological characteristics and clinically negative nodes not suitable for endoscopic treatment because this early stage disease shows limited lymph node metastasis incidence and excellent overall survival. Considering that the D2 gastrectomy has a negative impact on the quality of life of gastric cancer patients due to the post-gastrectomy functional results, a concept of a more targeted lymph node dissection, when appropriate, is certainly appealing. It is yet to be proven whether sentinel lymph node navigation surgery can fulfill such expectations providing the appropriate balance between morbidity and oncological safety in selected gastric cancer patients.

Abstract
BACKGROUND Small studies suggest improvement of cardiovascular risk profiles and reduced cardiovascular mortality after gastrectomy for gastric cancer. In our study using national health insurance data, we investigated coronary heart disease (CHD) and ischemic stroke incidence among gastric cancer patients who received gastrectomy compared with general population controls. METHODS A total of 98,936 gastric cancer patients were included in the study and matched to non-cancer controls via 1:1 propensity score matching. Competing risk regression analysis was used to determine the relative risk of CHD and ischemic stroke, with cancer mortality as the competing risk. Changes in cardiovascular risk profile before and after gastrectomy were tested, and factors associated with CHD or ischemic stroke incidence among gastric cancer patients were analyzed. RESULTS Compared with the matched controls, gastric cancer patients who received gastrectomy were shown to have a decreased risk for both CHD (subdistribution hazard ratio [SHR] 0.60, 95% confidence interval [CI] 0.57-0.63) and ischemic stroke (SHR 0.72, 95% CI 0.69-0.75). Decreases in body mass index (BMI), blood pressure, blood sugar, and lipid and hemoglobin levels were marked after gastrectomy. Among gastric cancer patients, those who lost > 5% of their body weight were at lower risk of developing CHD (SHR 0.82, 95% CI 0.71-0.96) and ischemic stroke (SHR 0.85, 95% CI 0.75-0.98). CONCLUSIONS CHD and ischemic stroke risk decreased after gastrectomy. The amount of weight loss and accompanying metabolic changes seemed to mediate the reduction of such risk. Reassessment of cardiovascular risk factors after gastrectomy and consideration of cardiovascular risk in the selection of treatment modality are suggested.

Abstract
OBJECTIVE The purpose of this study was to explore and understand how surgeons distribute tasks during a laparoscopic gastrectomy for gastric cancer in an academic teaching environment. DESIGN An anonymous, cross-sectional, census survey was used to poll trainees' and staff members' opinions pertaining to laparoscopic gastrectomy. SETTING Academic and community tertiary teaching hospitals, affiliated with the University of Toronto. PARTICIPANTS All surgeons, within the Department of General Surgery at the University of Toronto, who practice laparoscopic gastrectomy for gastric cancer, were invited to participate. All general surgery residents, postgraduate year 1-5, minimally invasive surgery and surgical oncology fellows at the University of Toronto were invited to participate. Overall response rate was 74.35% (n = 87/117). RESULTS The results suggested that trainees do not routinely perform the major operative steps. Trainees agreed with faculty in this regard; however, there was a statistically significant difference in opinions, related to the degree of the perceived active operating of the trainees. There was also a difference in opinion, between trainees and faculty, regarding the common reasons for takeover. CONCLUSIONS The present survey highlights that current level of active exposure of surgical trainees to laparoscopic gastric surgery might be insufficient. A lack of role clarity may further hinder an optimal educational experience during these cases. Adopting a stepwise approach, with task deconstruction, could optimize training. Additional training modalities may be required to ensure technical proficiency is acquired before independent practice.

Abstract
The use of reduced port laparoscopic surgery (RPS) has become increasingly popular. The concept of RPS includes all procedures derived from various efforts minimizing the invasiveness of surgery, with single-incision laparoscopic surgery (SILS) being the ultimate reduced port technique. Reduced-port laparoscopic gastrectomy (RPLG) for gastric cancer has not yet been fully established and still has issues such as feasibility, oncological validity, training, and education. The short-term results of reported studies are acceptable. However, long-term results that verify positive results or radical cure even in cases of cancer have not yet been published. Patients for whom RPLG is indicated should be selected carefully. Prospective multicenter studies should be conducted to establish RPS as a truly evidence-based practice that addresses not only cosmesis but also the appropriate balance between minimal invasiveness and radical cure.

Abstract
Single-incision laparoscopic total gastrectomy for gastric cancer has recently been reported by Seoul National University Bundang Hospital. However, this is not a popular procedure primarily because of the technical difficulties involved in achieving consistent intracorporeal esophagojejunostomy. At Seoul National University Bundang Hospital, we recently introduced a simple, easy-to-use, low-profile laparoscopic manual scope holder that enables the maintenance of a stable field of view, the most demanding condition in single-port gastrectomy. In this technical report, we describe in detail the world's first solo single-incision laparoscopic total gastrectomy with D1+ lymph node dissection and intracorporeal esophagojejunostomy for proximal early gastric cancer.

Abstract
BACKGROUND Robot-assisted gastrectomy has been reported as a safe alternative to the conventional laparoscopy or open approach for treating early gastric carcinoma. To date, however, there are a limited number of published reports available in the literature. METHODS We assess the current status of robotic surgery in the treatment of gastric cancer, focusing on the technical details and oncological considerations. RESULTS In gastric surgery, the biggest advantage of robotic surgery is the ease and reproducibility of D2-lymphadenectomy. Reports show that even the intracorporeal digestive restoration is facilitated by use of the robotic approach, particularly following total gastrectomy. Additionally, the accuracy of robotic dissection is confirmed by decreased blood loss, as reported in series comparing robot-assisted with laparoscopic gastrectomy. The learning curve and technical reproducibility also appear to be shorter with robotic surgery and, consequently, robotics can help to standardize and diffuse minimally invasive surgery in the treatment of gastric cancer, even in the later stages. This is important because the application of minimally invasive surgery is limited by the complexity of performing a D2-lymphadenectomy. The potential to reproduce D2-lymphadenectomy, enlarged resections, and complex reconstructions provides robotic surgery with an important role in the therapeutic strategy of advanced gastric cancer. CONCLUSIONS While published reports have shown no significant differences in surgical morbidity, mortality, or oncological adequacy between robot-assisted and conventional laparoscopic gastrectomy, more studies are needed to assess the indications and oncological effectiveness of robotic use in the treatment of gastric carcinoma. Herein, the authors assess the current status of robotic surgery in the treatment of gastric cancer, focusing on the technical details and oncological considerations.

Abstract
Reduced port laparoscopic surgery has been used increasingly. It is a concept that has grown out of the various efforts aimed at minimally invasive surgery, with SILS being the ultimate reduced port technique. Reduced port laparoscopic surgery has been used to perform sleeve gastrectomy in bariatric surgery and excision of benign gastric submucosal tumor, applications that generally do not require lymph node dissection or complicated reconstruction. It can be done safely, result in a permanent cure, and offer good cosmetic outcomes. Reduced port laparoscopic surgery for gastric cancer has a short history, and its usefulness has not yet been fully established. This review describes the present situation and challenges faced as well as standardized procedures and the future prospects of reduced port laparoscopic gastrectomy for gastric cancer, which my team performs almost daily. These aspects of reduced port laparoscopic surgery are presented in light of the literature.

Surg Endosc 2014; 29:1522-9. [PMID: 25294524 DOI: 10.1007/s00464-014-3836-8] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2014] [Accepted: 08/21/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND Intracorporeal Billroth I (ICBI) (delta-shaped) anastomosis is being increasingly used for laparoscopic distal gastrectomy. However, few studies have focused on the safety and feasibility of adopting this new technique. The present study aimed to review the surgical outcomes after the initial experience of performing ICBI anastomosis and to evaluate whether this technique can be safely adopted without increasing operative risk during the early learning process. METHODS Forty-two consecutive patients who underwent ICBI anastomosis with laparoscopic distal gastrectomy by a single surgeon were enrolled, and their operative outcomes and hospital course were compared with those of 179 patients who underwent conventional extracorporeal Billroth I (ECBI) anastomosis by the same operator. The learning curve was assessed by evaluating the moving average of anastomosis time. RESULTS The operating time in the ICBI group was significantly longer than that in the ECBI group (142 vs. 116 min, p < 0.001). However, there were no significant differences in the postoperative hospital course such as gas passage, diet initiation, postoperative fever, and hospital stay between the two groups. Postoperative morbidity did not significantly differ between the ICBI and ECBI groups (7.1 vs. 12.3 %, p = 0.428). No anastomosis-related complications occurred in the ICBI group. The mean anastomosis time for ICBI anastomosis was 24 ± 5 min, and the anastomosis average time curve showed that it reached a plateau approximately after the 14th case. CONCLUSIONS ICBI anastomosis has a steep learning curve without increasing operative risk in the early learning process, when performed by experienced laparoscopic surgeons. The technical feasibility and clinical advantages of intracorporeal anastomosis need to be proven in future clinical trials.

Abstract
Background Although recent trends in laparoscopic procedures have been toward minimizing the number of incisions, four or five ports are normally required to complete laparoscopic gastrectomy because of the complexity of this procedure. Multi-channel ports, such as the SILS port (Covidien, JAPAN), are now available and are crucial for performing single-incision laparoscopic surgery (SILS) or reduced port surgery (RPS). We carried out reduced port distal gastrectomy (RPDG) using a dual-port method with a SILS port. Methods Ten patients who were diagnosed as early stage gastric cancer were offered the RPDG. Mean age and body mass index (BMI) were 68.1 and 21.4, respectively. No distant metastasis or regional lymph node swelling was seen in any case. A 5-mm flexible scope (Olympus, JAPAN) and SILS port were used and a nylon ligature with a straight needle, instead of a surgical instrument, was available to raise the gastric wall. Results The average operative time was 266.9 ± 38.3 min and blood loss was 37.8 ± 56.8 ml. Patients recovered well and experienced no complications after surgery. All patients could tolerate soft meals on the first day after surgery and the average hospital stay was 8.1 days. Past conventional LAG cases were evaluated to compare the short-term outcome and no difference was seen in the mean operative time or operative blood loss. The length of hospital stay after surgery was shorter for the RPDG group than the conventional operation group (p < 0.0001). Interestingly, the trend of serum CRP elevation after surgery was lower in the RPDG group than the conventional LAG group (p = 0.053). Conclusions
Although the benefits of RPS have not been established, this type of surgery may be expected to have some advantages. Cosmetic benefits and shorter hospital stays are clear advantages. Less invasiveness can be expected according to the trend of serum CRP elevation after RPDG.

Abstract
BACKGROUND The purpose of this study was to show the feasibility and safety of pure single-port laparoscopic distal gastrectomy (SDG) by comparing its short-term outcomes with those of conventional multiport totally laparoscopic distal gastrectomy (TLDG). STUDY DESIGN Prospectively collected data of 50 gastric cancer patients who underwent pure SDG from November 2011 through October 2013 were compared with the matched data of 50 TLDG patients. RESULTS Mean operation time (144.5 vs 140.3 minutes; p = 0.561) and number of harvested lymph nodes (51.7 ± 16.3 vs 52.4 ± 17.9; p = 0.836) were comparable. Estimated blood loss was lower in the SDG patients (50.5 ± 31.5 mL vs 87.5 ± 79.6 mL; p = 0.007). Postoperative recovery was faster in the SDG patients in terms of lower maximum pain score on the operative day (6.1 ± 1.4 vs 6.9 ± 1.5; p = 0.015) and postoperative day 1 (4.6 ± 1.0 vs 5.5 ± 1.4; p < 0.001), less use of parenteral analgesics (0.8 ± 1.0 vs 1.4 ± 1.0; p = 0.020), and less increase in C-reactive protein level on postoperative day 5 (4.57 ± 6.26 mg/L vs 8.51 ± 5.25 mg/L; p = 0.008). Postoperative morbidity occurred in 6 (12%) and 5 (10%) patients in the SDG and TLDG group, respectively. CONCLUSIONS This study showed that pure SDG is both safe and feasible for early gastric cancer, with similar operation time and better short-term outcomes than TLDG in terms of postoperative pain, estimated blood loss, inflammatory reaction, and cosmetic result.

Abstract
The theory behind using sentinel node mapping and biopsy in gastric cancer surgery, the so-called sentinel node navigation surgery, is to limit the extent of surgical tissue dissection around the affected organ and subsequently the accompanied morbidity. However, obstacles on the clinical correspondence of sentinel node navigation surgery in everyday practice have occasionally alleviated researchers’ interest on the topic. Only recently with the widespread use of minimally invasive surgical techniques, i.e., laparoscopic gastric cancer resections, surgical community’s interest on the topic have been unavoidably reflated. Double tracer methods appear superior compared to single tracer techniques. Ongoing research is now focused on the invention of new lymph node detection methods utilizing sophisticated technology such as infrared ray endoscopy, florescence imaging and near-infrared technology. Despite its notable limitations, hematoxylin/eosin is still the mainstay staining for assessing the metastatic status of an identified lymph node. An intra-operatively verified metastatic sentinel lymph node will dictate the need for further conventional lymph node dissection. Thus, laparoscopic resection of the gastric primary tumor combined with the appropriate lymph node dissection as determined by the process of sentinel lymph node status characterization represents an option for early gastric cancer. Patients with T3 or more advanced disease should still be managed conventionally with resection plus standard lymph node dissection.

Abstract
BACKGROUND Metastatic cancers of the paratesticular tissue are very rare; however, the most frequent primary site of spermatic cord metastasis is the gastrointestinal tract. CASE PRESENTATION We recently observed two cases of late-onset metastatic adenocarcinoma of the spermatic cord. Both patients complained of groin discomfort with a palpable mass in the scrotum and inguinal area. Radical orchiectomy and adjuvant chemotherapy were performed in both patients. Although the prognosis of patients with metastatic adenocarcinoma of the spermatic cord is typically poor, the prognosis of our patients was favorable after follow-up for 14 to 18 months. CONCLUSIONS In patients with groin discomfort or swelling and a history of gastric cancer, metastatic adenocarcinoma should be included in the differential diagnosis for early detection of tumors.

Abstract
PURPOSE In the literature, the manifestations of gastric cancer have been described based on all patients. In recent times, interest has focused on the subgroup of young patients. In the following analysis, the subgroup of young patients (< 50y) is compared with an older reference group (≥ 50y). MATERIAL AND METHODS Between 01.01.1995 and 31.12.2005, 482 patients with a previously untreated gastric cancer underwent surgery. Fifty-six patients in this group were under 50 years of age, and the remaining 367 patients constituted the reference group. All data were recorded prospectively and analyzed retrospectively from the clinical cancer registry of the University of Erlangen. RESULTS The analysis showed that the young patients had a similar tumor stage distribution. Diffuse tumor stages in the Laurén classification occurred significantly more often. The postoperative complication rate was similar, but the hospital mortality rate was significantly lower. The young patients had an obvious, but not significant, 5-year survival advantage in all tumor stages. CONCLUSIONS Younger patients can be operated on with greater confidence as they have a significantly lower hospital mortality rate. They exhibit markedly better 5-year survival at all tumor stages. According to our data, there is nothing to support the general belief that young patients have a poorer disease course. Further clinical and experimental studies are necessary to investigate this group more precisely.

Abstract
Hepatobiliary surgery is a challenging surgical subspecialty that requires highly specialized training and an adequate level of experience in order to be performed safely. As a result, minimally invasive hepatobiliary surgery has been met with slower acceptance as compared to other subspecialties, with many surgeons in the field still reluctant about the approach. On the other hand, gastric surgery is a very popular field of surgery with an extensive amount of literature especially regarding open and laparoscopic surgery but not much about the robotic approach especially for oncological disease. Recent development of the robotic platform has provided a tool able to overcome many of the limitations of conventional laparoscopic hepatobiliary surgery. Augmented dexterity enabled by the endowristed movements, software filtration of the surgeon's movements, and high-definition three-dimensional vision provided by the stereoscopic camera, allow for steady and careful dissection of the liver hilum structures, as well as prompt and precise endosuturing in cases of intraoperative bleeding. These advantages have fostered many centers to widen the indications for minimally invasive hepatobiliary and gastric surgery, with encouraging initial results. As one of the surgical groups that has performed the largest number of robot-assisted procedures worldwide, we provide a review of the state of the art in minimally invasive robot-assisted hepatobiliary and gastric surgery.The English full-text version of this article is available at SpringerLink (under supplemental).

Abstract
BACKGROUND The role of laparoscopic surgery for the treatment of gastric cancer is still controversial, particularly in terms of oncologic efficacy. The aim of this study was to compare short-term outcomes of laparoscopic and open resection for gastric cancer at a single Western institution. SUBJECTS AND METHODS This study was designed as a matched cohort study from a prospective gastric cancer database. Forty-one patients undergoing laparoscopic gastrectomy for gastric cancer between June 2008 and January 2012 were matched with 41 patients undergoing open gastrectomy in the same time period. Patient pairing was done according to age, gender, type of gastrectomy (subtotal or total), and tumor stage via a randomized statistical method. The short-term outcomes and oncologic adequacy of the laparoscopic and open procedures were compared. A D2 lymph node dissection was performed in the majority of patients in both groups. RESULTS The two study groups were similar with respect to patient and tumor characteristics. Laparoscopic procedures were associated with a decreased blood loss (118.7 versus 312.4 mL, P<.005), incidence of surgery-unrelated complications (3 versus 9 patients, P<.05), and duration of hospital stay (8.1 versus 11.5 days, P<.05) but increased operative time for both subtotal (223.5 versus 158.2 minutes, P<.001) and total (298.1 versus 185.5 minutes, P<.001) gastrectomies. The mean number of retrieved lymph nodes after D2 dissection was similar: 30.0 for laparoscopic and 29.7 for open patients. CONCLUSIONS Within the limitations of a nonrandomized analysis, this study shows that the laparoscopic approach is a safe and oncologically adequate option for the treatment of gastric cancer, which compares favorably with open gastrectomy in short-term outcomes.

Abstract
Purpose The intraumbilical incision is being used more frequently, with increasing cases of single incision laparoscopic surgery. Since the umbilicus is deeper than the surrounding wall, it has abundant bacteria. No study has compared the adverse outcomes of periumbilical and intraumbilical incisions. We analyzed the wound complication rates of perforated appendicitis patients according to the types of umbilical incision. Methods A retrospective review was done of 280 patients with perforated appendicitis. One hundred fifty nine patients were treated with the intraumbilical incision, and 121 patients were treated with the periumbilical incision. We compared the perioperative outcomes according to each laparoscopic incision. Results There was no difference in operation time, postoperative hospital stay and analgesic requirement between the two groups. One case in the intraumbilical group (0.6%) and three cases in the periumbilical group (2.5%) developed wound infections. The umbilical complication rate showed no difference. Conclusion The wound complication rate of intraumbilical and periumbilical incisions are not different. Although this retrospective study has inherent limitations, the intraumbilical incision seems to be a safe and feasible alternative for the periumbilical incision that can be easier to perform, with better cosmetic results.

Abstract
Gastric cancer is common worldwide. Tumor location and disease stage differ between Asian and Western countries. Western patients often have higher BMIs and comorbidities that may make laparoscopic resections challenging. Multiple trials from Asian countries demonstrate the benefits of laparoscopic gastrectomy for early gastric cancer while maintaining equivalent short-term and long-term oncologic outcomes compared with open surgery. The outcomes of laparoscopy seem to offer equivalent results to open surgery. In the United States, laparoscopic gastrectomy remains in its infancy and is somewhat controversial. This article summarizes the literature on the epidemiology, operative considerations and approaches, and outcomes for laparoscopic gastrectomy.

Abstract
BACKGROUND Bariatric surgery effectively induces weight loss and resolves cardiovascular comorbidities in obese patients. We investigated cardiovascular and all-cause mortality in patients who underwent gastrectomies for early gastric cancer (EGC) and analyzed the changes in metabolic parameters after surgery. METHODS A total of 2,477 patients who underwent gastrectomies for EGC between 1995 and 2004 were enrolled in the study and followed for mortality through 2007. Standardized mortality ratios (SMRs) were calculated using sex- and age-matched mortality in the general Korean population in 2005. Effects of gastrectomy on changes in body weight and metabolic parameters were investigated in 51 of the patients before and after surgery. RESULTS During the 15,096.4 person-years of follow-up, 244 deaths were recorded. The all-cause mortality was not significantly different from that of the general population (SMR [95 % confidence interval (CI)] = 1.01 [0.89 - 1.14]); however, cardiovascular mortality was significantly lower (SMR = 0.35 [0.22 - 0.53]). In the 51 patients included in the second part of the study, significant reductions in body weight and visceral fat areas occurred after surgery, regardless of whether the patients were previously obese. Triglycerides, LDL-cholesterol, and plasminogen activator inhibitor-1 levels were significantly decreased, whereas HDL-cholesterol and adiponectin levels were increased. Carotid intima-media thickness also was significantly decreased in previously obese and nonobese patients. CONCLUSIONS Patients with EGC who undergo gastrectomy have a lower cardiovascular mortality but similar all-cause mortality as that of the general population. In these patients, a significant reduction in body weight and visceral fat after surgery may improve impaired lipid metabolism and prevent atherosclerotic changes.
