RESUMO
BACKGROUND: The SARS-CoV2 virus has been identified in abdominal cavity of the COVID-19 patients. Therefore, the potential viral transmission from any surgical created smoke in these patients is of concern especially in laparoscopic surgery. This study aimed to compare the amount of surgical smoke and surgical field contamination between laparoscopic and open surgery in fresh cadavers. METHODS: Cholecystectomy in 12 cadavers was performed and they were divided into 4 groups: laparoscopic approach with or without smoke evacuator, and open approach with or without smoke evacuator. The increased particle counts in surgical smoke of each group were analyzed. In the model of appendectomy, surgical field contamination under ultraviolet light and visual contamination scale between laparoscopic and open approach were compared. RESULTS: Open cholecystectomy significantly produced a greater amount of overall particle sizes, particle sizes < 5 µm and particle sizes ≥ 5 µm than laparoscopic cholecystectomy (10,307 × 103 vs 3738 × 103, 10,226 × 103 vs 3685 × 103 and 81 × 103 vs 53 × 103 count/m3, respectively at p < 0.05). The use of smoke evacuator led to decrease in the amount of overall particle sizes of 58% and 32.4% in the open and laparoscopic chelecystectomy respectively. Median (interquatile range) visual contamination scale of surgical field in open appendectomy [3.50 (2.33, 4.67)] was significantly greater than laparoscopic appendectomy [1.50 (0.67, 2.33)] at p < 0.001. CONCLUSIONS: Laparoscopic cholecystectomy yielded less smoke-related particles than open cholecystectomy. The use of smoke evacuator, abeit non-significantly, reduced the particles in both open and laparoscopic cholecystectomy. Laparoscopic appendectomy had a lower degree of surgical field contamination than the open approach.

BACKGROUND: Situs inversus is a rare and silent autosomal recessive disorder occurring in 1:5,000 to 1:20,000 individuals. Laparoscopic cholecystectomy, a standard treatment for gallbladder disease in the general population, is very challenging in patients with situs inversus, especially for right-handed surgeons. We herein report a case involving our modified laparoscopic cholecystectomy technique for right-handed surgeons in a Thai patient with situs inversus who developed a symptomatic gallstone. We also include a short review of the literature. CASE PRESENTATION: A 39-year-old female patient with dextrocardia presented with a 5-month history of episodic biliary colic. Abdominal ultrasonography revealed a left-sided gallbladder with gallstones. We performed laparoscopic cholecystectomy with our modified technique including port relocation. The operation went well, and our patient recovered satisfactorily. CONCLUSION: Laparoscopic cholecystectomy in patients with a left-sided gallbladder is not often confidently performed by right-handed surgeons. However, some modifications of "mirror image" ports focused on the more ergonomic port position are the keys to successful completion of this operation. The patient will thus still obtain benefits from this standard minimally invasive technique.

OBJECTIVE: To demonstrate potential benefits of three-port hand-assisted laparoscopic sigmoidectomy (HALS) compared with open sigmoidectomy (OS) in terms of short-term outcomes and cost-benefit. MATERIAL AND METHOD: A retrospective review of a database of cases that matched 100 sigmoid cancer patients treated with sigmoidectomy at the Department of Surgery, Siriraj Hospital was performed. Short-term outcomes and costs of treatment were collected and analyzed. RESULTS: There were no differences in age, gender body mass index, American Society of Anesthesiologists' score, Charlson comorbidity index score, and previous surgery between OS and HALS groups. The three-port HALS group had significantly less blood loss (50 (5-400) mL vs. 120 (10-1,000) mL, p<0.001), faster time to regular diet (64.6±20.7 hours vs. 97.6±52.5 hours, p<0.001), and lower pain score (4.3±1.7 vs. 5.3±1.6, p = 0.008). The hospital-stay related cost was sign icantly lower in HALS group ($114 ($47-$789) vs. $190 ($57-$1,462), pAssuntos

RESUMO
OBJECTIVE: Endoscopic sphincteroplasty (ESPT) using a large CRETM Wireguided balloon dilatation is an alternative technique in removing a difficult common bile duct (CBD) stone. However the outcome and complications of endoscopic difficult CBD stone removal using ESPT have not been well demonstrated. The present study revealed the outcome of the technique which done by a single endoscopist. MATERIAL AND METHOD: Between January 2003 and December 2009, the retrospective study of ninety-three patients with CBD stones that underwent endoscopic retrograde cholangiopancreaticography (ERCP) for stone removal and had difficulty were enrolled. ESPT using a large CRE Wireguided balloon dilatation was performed in 62 patients. The success rate of complete stone clearance and post ERCP complications were analyzed RESULTS: In the aspect of complete stone removal, the success rate was 88.7%. Seven patients (11.3%) required adjunctive mechanical lithotripsy (ML) for complete stone clearance. This technique was associated with low complication rate (3.2%). Post ERCP bleeding was found in one patient (1.6%) with ESPT using a large CRE balloon dilatation. Mild post-ERCP pancreatitis occurred in only one patient. CONCLUSION: ESPT using large diameter CRE Wireguided balloon dilatation after biliary sphinctertomy is an effective technique for a difficult CBD stone removal associated with a lower rate of complications. This procedure can avoid unnecessary surgical CBD exploration for stone removal.

While endoscopic retrograde cholangiopancreatography (ERCP) remains the primary treatment modality for common bile duct stones (CBDS) or choledocholithiasis due to advancements in instruments, surgical intervention, known as common bile duct exploration (CBDE), is still necessary in cases of difficult CBDS, failed endoscopic treatment, or altered anatomy. Recent evidence also supports CBDE in patients requesting single-step cholecystectomy and bile duct stone removal with comparable outcomes. This review elucidates relevant clinical anatomy, selection indications, and outcomes to enhance surgical understanding. The selection between trans-cystic (TC) vs trans-choledochal (TD) approaches is described, along with stone removal techniques and ductal closure. Detailed surgical techniques and strategies for both the TC and TD approaches, including instrument selection, is also provided. Additionally, this review comprehensively addresses operation-specific complications such as bile leakage, stricture, and entrapment, and focuses on preventive measures and treatment strategies. This review aims to optimize the management of CBDS through laparoscopic CBDE, with the goal of improving patient outcomes and minimizing risks.
RESUMO
Background/Aims: Achalasia is a rare esophageal motility disease, for which peroral endoscopic myotomy (POEM) has emerged as a promising treatment option; however, recurrence remains a challenge. Timed barium esophagography (TBE) is a useful diagnostic tool and potential outcome predictor of achalasia. This study aimed to determine predictive tools for recurrence after POEM. Methods: This retrospective study enrolled achalasia patients who underwent POEM between January 2015 and December 2021. Patients were categorized into two groups using the 1-month post-POEM Eckardt scores and TBE: the discordant group (Eckardt score improved >50%, TBE decreased <50%) and the concordant group (both Eckardt score and TBE improved >50%). Recurrence was defined as a reincrease in the Eckardt score to more than three during follow-up. Results: Complete medical records were available in 30 patients who underwent POEM. Seventeen patients (56.7%) were classified into the discordant group, while 13 patients (43.3%) were in the concordant group. The overall recurrence rate was 11.9% at 1-year, increasing to 23.8% during the extended follow-up. The discordant group had a 6.87 fold higher recurrence rate than the concordant group (52.9% vs. 7.7%, p=0.017). Conclusions: These results strongly suggest that combining the Eckardt score with TBE can effectively predict recurrent achalasia after POEM. Patients in the discordant group had an elevated risk.
RESUMO
Hilar cholangiocarcinoma (HCCA) is one of the most common types of hepatobiliary cancers reported in the world including Asia-Pacific region. Early HCCA may be completely asymptomatic. When significant hilar obstruction develops, the patient presents with jaundice, pale stools, dark urine, pruritus, abdominal pain, and sometimes fever. Because no single test can establish the definite diagnosis then, a combination of many investigations such as tumor markers, tissue acquisition, computed tomography scan, magnetic resonance imaging/magnetic resonance cholangiopancreatography, endoscopic ultrasonography/intraductal ultrasonography, and advanced cholangioscopy is required. Surgery is the only curative treatment. Unfortunately, the majority of HCCA has a poor prognosis due to their advanced stage on presentation. Although there is no survival advantage, inoperable HCCA managed by palliative drainage may benefit from symptomatic improvement. Currently, there are three techniques of biliary drainage which include endoscopic, percutaneous, and surgical approaches. For nonsurgical approaches, stent is the most preferred device and there are two types of stents i.e. plastic and metal. Type of stent and number of stent for HCCA biliary drainage are subjected to debate because the decision is made under many grounds i.e. volume of liver drainage, life expectancy, expertise of the facility, etc. Recently, radio-frequency ablation and photodynamic therapy are promising techniques that may extend drainage patency. Through a review in the literature and regional data, the Asia-Pacific Working Group for hepatobiliary cancers has developed statements to assist clinicians in diagnosing and managing of HCCA. After voting anonymously using modified Delphi method, all final statements were determined for the level of evidence quality and strength of recommendation.

BACKGROUND: Despite the infrequency of trocar site hernias (TSHs), fascial closure continues to be recommended for their prevention when using a ≥ 10-mm trocar. AIM: To identify the necessity of fascial closure for a 12-mm nonbladed trocar incision in minimally invasive colorectal surgeries. METHODS: Between July 2010 and December 2018, all patients who underwent minimally invasive colorectal surgery at the Minimally Invasive Surgery Unit of Siriraj Hospital were retrospectively reviewed. All patients underwent cross-sectional imaging for TSH assessment. Clinicopathological characteristics were recorded. Incidence rates of TSH and postoperative results were analyzed. RESULTS: Of the 254 patients included, 70 (111 ports) were in the fascial closure (closed) group and 184 (279 ports) were in the nonfascial closure (open) group. The median follow up duration was 43 mo. During follow up, three patients in the open group developed TSHs, whereas none in the closed group developed the condition (1.1% vs 0%, P = 0.561). All TSHs occurred in the right lower abdomen. Patients whose drains were placed through the same incision had higher rates of TSHs compared with those without the drain. The open group had a significantly shorter operative time and lower blood loss than the closed group. CONCLUSION: Routine performance of fascial closure when using a 12-mm nonbladed trocar may not be needed. However, further prospective studies with cross-sectional imaging follow-up and larger sample size are needed to confirm this finding.
RESUMO
Background/Aims: The coronavirus disease 2019 pandemic has affected the worldwide practice of upper gastrointestinal endoscopy. Here we designed a modified N95 respirator with a channel for endoscope insertion and evaluated its efficacy in upper gastrointestinal endoscopy. Methods: Thirty patients scheduled for upper gastrointestinal endoscopy were randomized into the modified N95 (n=15) or control (n=15) group. The mask was placed on the patient after anesthesia administration and particles were counted every minute before (baseline) and during the procedure by a TSI AeroTrak particle counter (9306-04; TSI Inc.) and categorized by size (0.3, 0.5, 1, 3, 5, and 10 µm). Differences in particle counts between time points were recorded. Results: During the procedure, the modified N95 group displayed significantly smaller overall particle sizes than the control group (median [interquartile range], 231 [54-385] vs. 579 [213-1,379]×103/m3; p=0.056). However, the intervention group had a significant decrease in 0.3-µm particles (68 [-25-185] vs. 242 [72-588]×103/m3; p=0.045). No adverse events occurred in either group. The device did not cause any inconvenience to the endoscopists or patients. Conclusions: This modified N95 respirator reduced the number of particles, especially 0.3-µm particles, generated during upper gastrointestinal endoscopy.
RESUMO
OBJECTIVE: The present study was undertaken to evaluate the demographic data, endoscopic ultrasonography (EUS) characteristics of the sub-epithelial lesions, pathology results, complications and long-term follow-up of the patients whom referred for EUS evaluation at Siriraj Hospital. MATERIAL AND METHOD: From January 2008-June 2011, a total of 61 cases was referred for EUS evaluation due to subepithelial lesions. The endoscopic reports, pathology results and the patients' medical records were reviewed. The present study was approved by Siriraj Institutional Review Board. RESULTS: A total of 61 patients were referred for evaluation of subepithelial lesions, 6 of them were excluded. Thus, 55 cases were analyzed. The mean age was 57.7 +/- 13.8 years (27-87 years). Sixty seven percent were female. Only one-third of the patients had symptoms. The provisional diagnosis of the sub-epithelial lesions, regarding only clinical and endosonographic characteristics were GIST neuroendocrine tumor (NET), pancreatic rest, lipoma, granular cell tumor and others (70.9%, 9.1%, 9.1%, 3.6%, 3.6% and 3.6% respectively). All the lesions were diagnosed as GIST originating from either the forth layer (97.4%) or the second layer (2.6%) of gastric or duodenal wall. Fine needle aspiration (FNA) was performed in 13 patients (23.6%). The positive predictive value, negative predictive value and accuracy of diagnosis of GIST made by endosonographers based on only endosonographic characteristics were 85, 100 and 86% (95% CI: 62.4%-94.4%) respectively. CONCLUSION: Most of the subepithelial lesions which were referred for EUS evaluation at Siriraj Hospital were GISTs. The diagnosis of GISTcan be accurately made by using the EUS based on only endosonographic characteristics. FNA should be done for the large sized GIST. For small sized GIST (< 3 cm), FNA might not be beneficial but a 1year interval follow-up with EUS is recommended.

In the highly contagious coronavirus disease 2019 pandemic, aerosol-generating procedures (AGPs) are associated with high-risk of transmission. Upper gastrointestinal endoscopy is a procedure with the potential to cause dissemination of bodily fluids. At present, there is no consensus that endoscopy is defined as an AGP. This review discusses the current evidence on this topic with additional management. Prevailing publications on coronavirus related to upper gastrointestinal endoscopy and aerosolization from the PubMed and Scopus databases were searched and reviewed. Comparative quantitative analyses showed a significant elevation of particle numbers, implying that aerosols were generated by upper gastrointestinal endoscopy. The associated source events have also been reported. To reduce the dispersion, certain protective measures have been developed. Endoscopic unit protocols are recommended for the concerned personnel. Therefore, upper gastrointestinal endoscopy should be classified as an AGP. Proper practices should be adopted by healthcare workers and patients.
RESUMO
Endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) play increasingly prominent roles in the diagnosis and management of pancreatic cysts. The Asian Consortium of Endoscopic Ultrasound was recently formed to conduct collaborative research in this area. This is a review of literature on true pancreatic cysts. Due to the lack of systematic studies, there are no robust data on the true incidence of pancreatic cystic lesions in Asia and any change in over the recent decades. Certain EUS morphological features have been used to predict particular types of pancreatic cysts. Pancreatic cyst fluid viscosity, cytology, pancreatic enzymes, and tumor markers, in particular carcinoembryonic antigen, can aid in the diagnosis of pancreatic cysts. Hemorrhage and infection are the most common complications of EUS-FNA of pancreatic cysts. Pancreatic cysts can either be observed or resected depending on the benign or malignant nature, or malignant potential of the lesions. Guidelines from an international consensus did not require positive cytological findings to be present in their recommendation for resection, which included all mucinous cystic neoplasms, all main-duct intraductal papillary mucinous neoplasms (IPMN), all mixed IPMN, symptomatic side-branch IPMN, and side-branch IPMN larger than 3 cm. In patients with poor surgical risks, EUS-guided cyst ablation of mucinous pancreatic cysts is an alternative. As long-term prospective data on pancreatic cysts are still not available in Asia, management strategies are largely based on risk stratification by surgical risk and malignant potential. Gene expression profiling of pancreatic cyst fluid and confocal laser endomicroscopic examination of pancreatic cysts are novel techniques currently being studied.

Traditionally, there are several approaches to manage left-sided colonic carcinoma obstruction, such as tumor resection with primary anastomosis, tumor resection with end-colostomy and loop-colostomy. Recently, colonic stent insertion was introduced as a bridge prior to definite surgery. We demonstrated a hybrid approach for obstructed sigmoid carcinoma using colonic stent, followed by single incision laparoscopic colectomy (SILC). A 58 year-old man presented with complete left-sided colonic obstruction. He underwent emergency colonoscopy with metallic stent placement. One week later, he was performed SILC. He recovered well after the operation without any postoperative complications. The pathological result showed adequacy of oncologic resection. This hybrid approach of colonic stent insertion and SILC can be safely performed.

BACKGROUND: Single-incision laparoscopic colectomy (SILC) was introduced as a novel minimally invasive technique. The benefits of this technique include reducing number of the incision and cosmetic improvement. Unlike the conventional laparoscopic colectomy, majority of previously reported SILC need to be performed using special curved or articulated instruments. The purpose of this study is to demonstrate our initial experience of SILC, which could be performed using the standard laparoscopic instruments. MATERIAL AND METHODS: Retrospective review of 14 patients who underwent SILC at Siriraj Hospital from May to December 2010, patient's demographic data, perioperative outcomes, early postoperative complications and pathological data were collected and analyzed. RESULTS: The mean age of all patients was 60 years. The most common operation with SILC was sigmoidectomy (n = 9), followed by right hemicolectomy (n = 2), left hemicolectomy (n = 1), anterior resection (n = 1), and total colectomy (n = 1). The trocar insertion techniques were multi-fascial incision using regular port (n = 11) and GelPOINT(®) (n = 3). The mean operative time was 155 minutes (range 90-280) and the mean estimate blood loss was 32.1 mL (range 10-100). All patients were successfully operated without conversion. The mean length of hospital stay was 9 days (range 5-20). There was no mortality. The pathological results revealed colorectal cancer (n = 12), neoplastic polyp (n = 1) and Familial adenomatous polyposis (FAP) (n = 1). The mean number of lymph nodes retrieval was 16.6 (range 3-34). CONCLUSION: SILC can successfully and safely be performed with standard laparoscopic instruments. This technique might be an alternative procedure to conventional laparoscopic colectomy with better cosmetic result.

Unlike endoscopic retrograde cholangiopancreatography (ERCP) service, endoscopic ultrasonography (EUS) service in Thailand is at its elementary state. Currently, there are only 11 hospitals in Thailand carrying out EUS whereas there are more than 50 hospitals carrying out ERCP. This is a multicenter questionnaire survey that obtained information on EUS practice for pancreatic cysts. Of those 11 hospitals, only three hospitals provided enough number of patients with pancreatic cysts undergoing EUS. There were many differences in endosonographers opinions regarding specific information in the pancreatic cyst. In addition, the threshold to carry out and not to carry out fine needle aspiration are varies.

BACKGROUND: Early gastric cancer (EGC) defined as gastric cancer involving up to submucosal layer, regardless of lymph node metastasis, is increasingly found at Siriraj Hospital. Understanding the characteristic of EGC and result of surgical management for EGC can help to choose the optimal treatment. In the present study, the authors reported the first case series in Thailand. MATERIAL AND METHOD: The authors analyzed 21 consecutive EGC patients treated with gastrectomy with lymph node dissection between September 2001 and December 2009 at Minimally Invasive Surgery Center, Division of General Surgery, Department of Surgery, Siriraj Hospital, Mahidol University, Thailand. RESULTS: Ratio of EGC to total cases of gastric cancer was increasing yearly, from 1.8% in 2006 to 8.1% in 2009 at Siriraj Hospital. The most common type of EGC was type IIc (66.7%) while type III was found in 19%, and type I in 14.3%. The tumor invaded mucosal layer in 42.9% and submucosal layer in 57.1% of the patients. For N staging, 76.2% of the patients were N0 while N1 was 19% and N2 was 4.8%. Overall, lymph node metastasis was found in 23.8%. For mucosal cancer (m), no lymph node metastasis was seen while for submucosal cancer (sm) five cases (41.7%) had lymph node metastasis, especially in one patient that the metastasis was in N2 group. Lymphatic invasion was seen in 14.3% of cases. All cases with lymphatic invasion were all submucosal cancer. Overall staging was stage 1a in 76.2%, stage 1b in 19%, and stage 2 in 4.8%. Morbidity was seen in 14.3% of the cases. No mortality was seen. The survival was excellent with no recurrence found during the follow-up period of the present study (mean 30.53 months). CONCLUSION: Surgery for EGC has good results with minimal complications and excellent 5-year survival. Less invasive treatment has become the option for EGC. Understanding the characteristic of EGC and careful selection to assign appropriate treatment is important to improve the result in the treatment of EGC.

BACKGROUND AND OBJECTIVES: Laparoscopic cholecystectomy with common bile duct exploration (LC with LCBDE) remains the preferred technique for difficult common bile duct stone (CBDS) removal. The chopstick method uses commonly available instruments and may be cost-saving compared to other techniques. We studied the outcome of LCBDE using the chopstick technique to determine if it could be considered a first-choice method. METHODS: Data from all patients that underwent LCBDE from January 1, 2012 to April 30, 2019 were retrospectively analyzed. A standard 4-port incision and CBDS permitted extraction with two laparoscopic instruments by chopstick technique via vertical choledochotomy. Demographic data, stone clearance rate, surgical outcomes, complications, and other associated factors were evaluated. RESULTS: Thirty-two patients underwent LCBDE. The mean number of preoperative endoscopic retrograde cholangiopancreatography (ERCP) sessions was 2.4. In 65.5% of cases, the CBDS was completely removed by the chopstick technique, while 96.9% of stones were removed after using additional tools. The need for additional instruments was associated with increased age, increased numbers of stones, longer period from the latest ERCP session, and previous upper abdominal surgery. The conversion rate to open surgery was 28.1% and was significantly associated with a history of upper abdominal surgery. CONCLUSION: The chopstick technique is a good alternative and could be considered as a first-line technique in LCBDE to remove the CBDS in cases with 1 to 2 large suprapancreatic CBDS due to instrument availability, cost-effectiveness, and comparable surgical outcomes.

For Choledochal cyst type I, complete excision of cyst with Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of robot-assisted total excision of a choledochal cyst type I and biliary reconstruction in a 14-year-old girl. No intraoperative complications or technical problems were encountered. An intraabdominal collection occurred and was successfully treated with continuous percutaneous drainage. At one-year follow-up, she is doing well without evidence of recurrent cholangitis.

BACKGROUND: Radical esophagectomy was reported to have prolonged survival in patients with esophageal cancer However, it is associated with high morbidity and mortality. Controversy still exists regarding value of radical esophagectomy MATERIAL AND METHOD: The authors analyzed the results, including complications and survival in 68 consecutive patients with esophageal cancer who were treated with transthoracic radical esophagectomy at the Department of Surgery, Siriraj hospital, Mahidol University between June 2002 and June 2008. RESULTS: There were 57 males and eight females with a mean age of 59.28 +/- 11.25 years. Regarding T staging, 81.5% of the patients were in T3 stage while 1.5% of the patients had Ti stage, 15.4% had T2 stage, and 1.5% had T4 stage. Lymph node metastasis (NI) was found in 63.1% of the patients and NO was in 36.9%. Most of the patients were in advanced stages with 53.8% in stage III, 44.6% in stage II, and 1.5% in stage I. The 5-year survival rate of the patients with node positive was significantly lower than the patients with node negative (p = 0.018). The survival was significantly better in stage Ilcompared to stage III (p = 0.012). Overall 5-year survival rate was 28. 5%. Most common complications were from pulmonary causes (22.1%), anastomotic leakage (8.8%), and wound infection (8.8%). Mortality rate was 4.41%. CONCLUSION: Radical esophagectomy was associated with relatively low mortality and acceptable survival. It should be considered in surgical treatment of patients with esophageal cancer

BACKGROUND: Extent of lymph node dissection still remains one of the most controversial issues regarding radical gastrectomy. Knowledge of the pattern and incidence of lymph node metastasis may help to define the optimal extent of lymph node dissection. MATERIAL AND METHOD: The authors analyzed lymph node metastasis and survival rate in 130 consecutive gastric cancer patients who underwent radical gastrectomy with D2 dissection between June 2001 and October 2008 at the Department of Surgery, Faculty of Medicine, Siriraj Hospital, Mahidol University, Thailand. RESULTS: For N staging, 28.5% of the patients were N0 while N1 was 40% and N2 was 31.5%. 44% of the patients with lymph node positive had metastasis up to group 2 lymph nodes. The patients with node positive had 5 year survival of 39% while the patients with node negative had survival of 73% (p = 0.003). Tumor at the middle part of the stomach had the most widespread lymph node metastasis compared to other regions. Lymph node group 7, 8 and 9 had a high incidence of lymph node metastasis especially for distal cancer while lymph node group 10, 11, 12 had lower incidence of metastasis. No mortality was seen in the present study. CONCLUSION: N staging, number of metastatic node > 5 and angiolymphatic invasion were the lymph node related factors contributing to survival. For radical gastrectomy, D2 dissection is required for adequate clearance of metastatic lymph nodes, which can be done without mortality.
