Delta-shaped anastomosis vs circular stapler anastomosis after laparoscopic distal gastrectomy with Billroth I reconstruction: A randomized controlled trial. Asian J Endosc Surg 2020; 13:301-310. [PMID: 31814306 DOI: 10.1111/ases.12770] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 09/30/2019] [Accepted: 10/23/2019] [Indexed: 12/26/2022]
Abstract
INTRODUCTION The aim of this study is to evaluate the efficacy of delta-shaped anastomosis compared to circular stapler anastomosis in laparoscopic distal gastrectomy with Billroth I reconstruction. METHODS This is a single-center randomized controlled study. Eligibility criteria included histologically proven gastric adenocarcinoma in the lower third of the stomach, clinical stage I tumor. Patients were preoperatively randomized to circular stapler anastomosis or delta-shaped anastomosis. The primary endpoint is the number of analgesics used during three days after surgery. We compared the surgical outcomes of the two groups. Postoperative quality of life was evaluated using the Postgastrectomy Syndrome Assessment Scale-45. This trial was registered at the UMIN Clinical Trials Registry as UMIN000025160. RESULTS Between December 2016 and September 2018, 39 patients (delta-shaped anastomosis 18, circular stapler anastomosis 21) were enrolled. There was no difference in the number of analgesics used during three days after surgery (median nine: delta-shaped anastomosis vs nine: circular stapler anastomosis, P = .91). There was no difference in the overall proportion with in-hospital grade II-IIIB surgical complications (11%: delta-shaped anastomosis, 14%: circular stapler anastomosis). There was no operation-related death in either arm. Regarding postoperative quality of life evaluated one month after surgery, diarrhea subscale was significantly worse in delta-shaped anastomosis than in circular stapler anastomosis. CONCLUSION We did not demonstrate the advantage of delta-shaped anastomosis in terms of postoperative pain. Since delta-shaped anastomosis tended to cause postoperative abdominal symptoms related to diarrhea, we should carefully apply the delta-shaped anastomosis to laparoscopic distal gastrectomy with Billroth I reconstruction.

Abstract
Purpose : Postoperative pancreatic fistula (POPF) is a serious complication after gastrectomy for gastric cancer. The purpose of this study is to identify the risk factor of POPF and evaluate C-reactive protein on postoperative day 1 (POD1) as the predictor for POPF after laparoscopic gastrectomy (LG). Methods : Between May 2013 and September 2016, 226 patients who underwent LG for gastric cancer were investigated. Patients were divided into 2 groups; POPF group (n = 17) and control group (n = 209). Clinicopathological factors were compared between 2 groups. Results : In POPF group, there are more male patients (p = 0.003) compared with control group. Preoperative factors, such as age, BMI, and prevalence of previous operation and comorbidity showed no significant difference between 2 groups. Regarding tumor factors and perioperative data such as blood loss and operative time, there were also no significant difference between 2 groups. POPF group showed longer postoperative hospital stay, and higher serum CRP level on POD1 (p < 0.0001). Multivariate analysis revealed that high CRP level on POD1 ( ≥ 3mg/dl) was independent risk factor of POPF. Conclusions : High serum CRP level on POD1 can predict the occurrence of POPF. J. Med. Invest. 66 : 285-288, August, 2019.

Abstract
Purpose The perigastric vagus nerve may play an important role in preserving function after gastrectomy, and intraoperative neurophysiologic tests might represent a feasible method of evaluating the vagus nerve. The purpose of this study is to assess the feasibility of neurophysiologic evaluations of the function and viability of perigastric vagus nerve branches during gastrectomy. Materials and Methods Thirteen patients (1 open total gastrectomy, 1 laparoscopic total gastrectomy, and 11 laparoscopic distal gastrectomy) were prospectively enrolled. The hepatic and celiac branches of the vagus nerve were exposed, and grabbing type stimulation electrodes were applied as follows: 10–30 mA intensity, 4 trains, 1,000 µs/train, and 5× frequency. Visible myocontractile movement and electrical signals were monitored via needle probes before and after gastrectomy. Gastrointestinal symptoms were evaluated preoperatively and postoperatively at 3 weeks and 3 months, respectively. Results Responses were observed after stimulating the celiac branch in 10, 9, 10, and 6 patients in the antrum, pylorus, duodenum, and proximal jejunum, respectively. Ten patients responded to hepatic branch stimulation at the duodenum. After vagus-preserving distal gastrectomy, 2 patients lost responses to the celiac branch at the duodenum and jejunum (1 each), and 1 patient lost response to the hepatic branch at the duodenum. Significant procedure-related complications and meaningful postoperative diarrhea were not observed. Conclusions Intraoperative neurophysiologic testing seems to be a feasible methodology for monitoring the perigastric vagus nerves. Innervation of the duodenum via the celiac branch and postoperative preservation of the function of the vagus nerves were confirmed in most patients.

Abstract
OBJECTIVES After gastrectomy with extended lymph node (LN) dissection, the damage of celiac plexus seems to cause of disorder of eating habits. To clarify the indication of gastrectomy with limited LN dissection for elderly patients, the pathological characteristics of advanced gastric cancer in elderly patients were examined in this study. METHODS Forty-seven patients aged ≥80 years with advanced gastric cancer (deeper than pT2) who underwent curative gastrectomy from 1998 to 2015 were enrolled. Patients were classified into two groups by extent of LN metastasis: Group A, with N0 or only perigastric LN metastasis (n = 33); Group B, LN metastasis beyond the perigastric area (n = 14). Pathological factors were then evaluated. RESULTS No significant differences were observed in age, sex, body mass index, American Society of Anesthesiologists physical status classification, serum level of carcinoembryonic antigen, surgical procedure, extent of LN dissection, and number of dissected LNs. Pathological findings showed no significant differences in tumor location, macroscopic type, histologic type, and lymphovascular invasion. However, significant differences were observed in tumor maximum diameter at the cut-off level of 40 mm (Group A: ≤40 mm, n = 10 and >40 mm, n = 23; Group B: ≤40 mm, n = 0 and >40 mm, n = 14; P = 0.02). CONCLUSION In the elderly patients, LN metastasis in advanced gastric cancer of ≤40 mm in diameter was limited to be within the perigastric area. Gastrectomy with only perigastric LN dissection may be adopted in these patients.

Abstract
INTRODUCTION Postoperative pancreatic fistula (POPF) is a serious complication after gastrectomy for gastric cancer. It is vitally important to detect signs of POPF in the early postoperative period and perform adequate management to avoid patient death. The aim of this study was to investigate the predictive indicators of POPF after laparoscopic gastrectomy for gastric cancer. METHODS The current study included 197 patients who were pathologically diagnosed with adenocarcinoma and underwent laparoscopic gastrectomy between January 2010 and December 2014 in our hospital. RESULT Nine patients (5.6%) developed POPF of grade III or higher according to the Clavien-Dindo classification. There was no statistical difference between POPF and various clinicopathological indicators, including age, gender, BMI, extent of lymph node dissection, and operative procedure. With respect to postoperative laboratory data, however, the serum level of C-reactive protein on postoperative day 3 was significantly related to the development of POPF. Receiver-operating characteristic analysis indicated that optimal cut-off value of the serum level of C-reactive protein on postoperative day 3 was 17.0 mg/dL, with a sensitivity of 74.0, specificity of 88.0, positive predictive value of 0.14, and negative predictive value of 0.99. CONCLUSION An elevated C-reactive protein level on postoperative day 3 can help physicians predict the likelihood of POPF and facilitate decision making regarding prompt clinical evaluation and therapeutic approaches for POPF.

Abstract
BACKGROUND Recently, enhanced recovery after surgery (ERAS) was widely used in the perioperative management of gastric cancer. The study aimed to evaluate the safety and effectiveness of ERAS in single-incision laparoscopic distal gastrectomy (SIDG). MATERIALS AND METHODS A total of 90 patients who received laparoscopic gastric cancer resection were divided into 3 groups: group A (n=30), underwent traditional multiport laparoscopic distal gastrectomy with conventional perioperative management; group B (n=30) underwent traditional multiport laparoscopic distal gastrectomy with ERAS concept; and group C (n=30), underwent SIDG with ERAS concept. Clinical data and gut function were assessed in 3 groups. RESULTS There were no significant differences in terms of postoperative complication, number of resected lymph nodes and blood loss among 3 groups. However, operation time was longer (P=0.003) and treatment cost was higher (P<0.001) in group C than that in group A and B. Group C had faster recovery of bowel function (P<0.001), shorter postoperative hospital stay (P=0.002), and less postoperative complication (P=0.044) than those in group A. There were no significant differences in terms of recovery of bowel function and postoperative hospital stay between group C and B (all P>0.05). The white blood cell counts were lower than group A and B (all P<0.05) and C-reactive protein in group C were lower than group A (P<0.05) and B (P>0.05). CONCLUSIONS The findings suggest that SIDG with ERAS may be a feasible and safe procedure for early gastric cancer because it provides a favorable cosmetic result while not compromising postoperative complications, number of resected lymph nodes, and blood loss.

Abstract
BACKGROUND The aim of this study was to compare surgical outcomes of patients with gastric cancer undergoing reduced port totally laparoscopic-assisted total gastrectomy (duet TLTG) with those of patients undergoing conventional laparoscopic-assisted total gastrectomy (LATG). MATERIALS AND METHODS Between January 2013 and 2015, 54 patients with gastric cancer underwent LATG at the Samsung Medical Center. Duet TLTG using 3 ports was performed in 30 patients, and conventional LATG using 5 ports was performed in 24 patients. Either extracorporeal or intracorporeal anastomosis was used for esophagojejunostomy. Surgical outcomes were compared between the operation methods. RESULTS The operating time was similar for duet TLTG and conventional LATG [222 min (range, 163 to 287 min) vs. 233 min (range, 170 to 310 min), respectively; P=0.807]. Blood loss during surgery was also similar between duet TLTG and conventional LATG groups [100 mL (range, 50 to 400 mL) vs. 175 mL (range, 50 to 400 mL), respectively; P=0.249]. The median number of nodes dissected [duet TLTG vs. conventional LATG, 47 (20 to 67) vs. 41 (22 to 70), P=0.338] was not different between groups. Pain scores were 3.9, 3.3, and 2.9, and 3.9, 3.4, and 2.8, at postoperative days 1, 3, and 5, respectively, in the duet TLTG and the conventional LATG groups (P=0.857, 0.659, and 0.427, respectively). Overall complication rates in the duet TLTG and conventional LATG groups were not significantly different (36.7% vs. 16.7%, P=0.103). CONCLUSIONS Duet TLTG is an acceptable procedure with quality of lymph node dissection, including the number of dissected lymph nodes and morbidity.

Abstract
The aim of this meta-analysis was to determine the feasibility of laparoscopic gastrectomy (LG) for elderly gastric cancer patients by comparing laparoscopic and conventional open gastrectomies (OG). Comprehensive search of the PubMed, EMBASE, and Cochrane Library databases revealed nine non-randomized controlled studies that compared LG and OG in elderly gastric cancer patients We then analyzed dichotomous or continuous parameters using odds ratios (ORs) or weighted mean differences (WMDs). Overall survival was estimated using hazard ratios (HRs) with a fixed effects or random effects model. We observed that the age distribution was similar between the LG and OG patient groups (WMD -0.22 95% CI, -1.26-0.82). LG patients experienced less blood loss (WMD -119.14 95% CI, -204.17--34.11) and had shorter hospital stays (WMD -3.48 95% CI, -5.41--1.56), but endured longer operation times (WMD 10.87 95% CI, 2.50-19.24). Postoperatively, LG patients exhibited lower incidences of postoperative morbidities (OR 0.59 95% CI, 0.43-0.79), surgery related morbidities (OR 0.58 95% CI, 0.41-0.81) and systemic morbidities (OR 0.56 95% CI, 0.38-0.82). We observed no differences between the LG and OG patient groups regarding anastomotic leakage (OR 0.69 95% CI, 0.34-1.41), mental disease (OR 0.72 95% CI, 0.37-1.41) and long term effects (HR 0.98 95% CI, 0.74-1.32). We therefore conclude that laparoscopic gastrectomy might be technically feasible for elderly gastric cancer patients.

Abstract
OBJECTIVE This study aims to answer the superiority of comparing laparoscopy-assisted distal gastrectomy (LADG) with open distal gastrectomy (ODG) in the treatment early gastric cancer (EGC). MATERIAL AND METHODS A comprehensive search up to May 31, 2014 was conducted on PubMed, Web of science, and the Cochrane Library. All eligible studies comparing LADG versus ODG were included. Data synthesis and statistical analysis were performed using RevMan 5.2 software. RESULTS Seven randomized controlled trials (RCTs) totaling 390 patients (195 LADG and 195 ODG) were analyzed. Compared to ODG, LADG showed longer operative time (WMD = 79.60; 95%CI = 59.86 to 99.35; P < 0.00001), but was associated with less blood loss (WMD = -108.11; 95%CI = -145.97 to -70.26; P < 0.00001), fewer administered analgesics (WMD = -1.70; 95%CI = -2.19 to -1.22; P < 0.00001), fewer number of harvested lymph node (WMD = -2.77; 95%CI = -4.38 to -1.16; P = 0.0007), lower incidence of postoperative complications (OR = 0.26; 95%CI = 0.13 to 0.54; P = 0.0003), shorter postoperative hospital stay (WMD = -1.0; 95% CI = -1.83 to -0.16; P = 0.02) and earlier passage of flatus (WMD = -0.62; 95% CI = -0.96 to -0.27; P = 0.0005). CONCLUSION This meta-analysis demonstrated that LADG significantly reduced blood loss, decreased the frequency of analgesic administration, faster recovery, a shorter hospital stay and fewer postoperative complications compared with ODG, though at the price of longer operative times and the number of harvested lymph nodes lesser as compared to ODG.

[PMID: 25617970 DOI: 10.1016/j.jss.2014.12.044] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2014] [Revised: 12/11/2014] [Accepted: 12/23/2014] [Indexed: 01/01/2023]
Abstract
BACKGROUND Obesity is known to be a preoperative risk factor for gastric cancer surgery. This study aimed to investigate the influence of obesity on the surgical outcomes of laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer. METHODS The clinical data of 131 patients with gastric cancer from January 2010-December 2013 were analyzed retrospectively. Perioperative outcomes were compared between 43 patients with a body mass index (BMI) ≥30 kg/m(2) (obese group) and 88 patients with a BMI <30 kg/m(2) (nonobese group) who underwent LADG. RESULTS Operation times were significantly longer for the obese group than for the nonobese group (234.1 ± 57.2 min versus 212.2 ± 43.5 min, P = 0.026). There were no statistically significant differences between two groups in terms of intraoperative blood loss, the number of retrieved lymph nodes, postoperative recovery, and postoperative complications (P > 0.05). During the follow-up period of 5 mo-49 mo (average, 36 mo), the overall survival rates were not significantly different between the two groups (80.0% [32/40] versus 81.9% [68/83], P > 0.05). The differences in recurrence and metastasis between the two groups were not statistically significant. CONCLUSIONS Our analysis revealed that LADG can be safely performed in patients with BMI ≥30. The procedure was considered to be difficult but sufficiently feasible.

Abstract
AIM: To test a new safe and simple technique for circular-stapled esophagojejunostomy in laparoscopic total gastrectomy (LATG).
METHODS: We selected 26 patients with gastric cancer who underwent LATG and Roux-en-Y gastrointestinal reconstruction with semi-end-to-end esophagojejunal anastomosis.
RESULTS: LATG with semi-end-to-end esophagojejunal anastomosis was successfully performed in all 26 patients. The average operation time was 257 ± 36 min, with an average anastomosis time of 51 ± 17 min and an average intraoperative blood loss of 88 ± 46 mL. The average postoperative hospital stay was 8 ± 3 d. There were no complications and no mortality in this series.
CONCLUSION: The application of semi-end-to-end esophagojejunal anastomosis after LATG is a safe and feasible procedure, which can be easily performed and has a short operation time in terms of anastomosis.

Abstract
PURPOSES In the current study, we evaluated the efficacy of dual-phase three-dimensional (3D) CT angiography (CTA) in the assessment of the vascular anatomy, especially the right hepatic artery (RHA), before gastrectomy. METHODS The study initially included 714 consecutive patients being treated for gastric cancer. A dual-phase contrast-enhanced CT scan using 32-multi detector-row CT was performed for all patients. RESULTS Among the 714 patients, 3D CTA clearly identified anomalies with the RHA arising from the superior mesenteric artery (SMA) in 49 cases (6.9 %). In Michels' classification type IX, the common hepatic artery (CHA) originates only from the SMA. Such cases exhibit defective anatomy for the CHA in conjunction with the celiac-splenic artery system, resulting in direct exposure of the portal vein beneath the #8a lymph node station, which was retrospectively confirmed by video in laparoscopic gastrectomy cases. Fused images of both 3D angiography and venography were obtained, and could have predicted the risk preoperatively, and the surgical finding confirmed its usefulness. CONCLUSION Preoperative evaluations using 3D CTA can provide more accurate information about the vessel anatomy. The fused images from 3D CTA have the potential to reduce the intraoperative risks for injuries to critical vessel, such as the portal vein, during gastrectomy.

Abstract
To evaluate the feasibility and safety of hand-assisted laparoscopic surgery for gastric cancer in obese patients, we compare the operative outcomes in obese patients who underwent hand-assisted laparoscopic distal gastrectomy (HALDG) and open distal gastrectomy (ODG). One hundred sixty-two obese patients with gastric cancer operated on in our department from January 2009 to December 2011 were divided into two groups: the open distal gastrectomy group (the ODG group) and the hand-assisted laparoscopic distal gastrectomy group (the HALDG group). Operative time, estimated blood loss, number of lymph node retrieval, wound length, times of analgesic injection, time to the first flatus, and postoperative hospital stay were compared between the two groups. Estimated blood loss, wound length, times of analgesic injection, time to the first flatus, and postoperative hospital stay were significantly less or shorter in the HALDG group than in the ODG group. There were no significant differences in tumor size, retrieved lymph nodes, American Joint Cancer Committee /Union Internationale Contre le Cancer staging, and resection margins between the two groups. Obesity should not be seen as a contraindication for HALDG. HALDG for obese patients is a safe, feasible, and oncologically sound procedure and has advantages over ODG.

Surg Endosc 2013; 28:866-74. [PMID: 24149848 DOI: 10.1007/s00464-013-3236-5] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2013] [Accepted: 09/21/2013] [Indexed: 02/06/2023]
Abstract
BACKGROUND Although surgeons normally use minimally invasive surgery (MIS) for patients with early gastric cancer, in Korea and Japan the procedure is also indicated for serosa-negative tumors. Serosal invasion is regarded to be a potential risk factor for peritoneal dissemination as a result of the effect of pneumoperitoneum and tumor manipulation during the operation. We compared operative outcomes between MIS and conventional open surgery for serosa-involved advanced gastric cancer patients who had a preoperative diagnosis of cancer without serosal invasion. METHODS A total of 61 patients (39 patients treated by MIS and 22 by open surgery) treated between 2003 and 2009 who were first diagnosed preoperatively as serosa negative on the basis of computed tomography, endoscopy, and endoscopic ultrasound but then diagnosed as serosa positive upon final pathology were studied. We retrospectively compared recurrence and survival between the two treatment groups. RESULTS Clinicopathologic characteristics, clinical stage, extent of surgery, and short-term operative outcome did not differ between the groups. 5-year overall survival (73.5 vs. 67.5 %, p = 0.518, respectively) and disease-free survival (67.8 vs. 54.2 %, p = 0.296, respectively) were comparable between the MIS and open surgery groups. There were recurrences in 12 patients in the MIS group and 11 patients in the open surgery group, with a median follow-up period of 64 months. Recurrence patterns did not differ between the groups; moreover, MIS did not increase peritoneal recurrences compared to open surgery (42.0 vs. 54.5 %, p = 0.537, respectively). In multivariate analyses, the type of surgery was not an independent prognostic factor. CONCLUSIONS Similar survival and recurrence patterns were observed in advanced gastric cancer patients preoperatively diagnosed as serosa negative who were treated either by MIS or open surgery. MIS may be safely applied in patients with serosa-positive tumors.

Abstract
BACKGROUND Despite the popularity of laparoscopic-assisted distal gastrectomy (LADG), studies have reported a high incidence of postoperative complications in patients who have had LADG. The present study explores the preoperative risk factors for complications from LADG. PATIENTS AND METHODS This study involves 1257 patients who underwent standardized LADG in a single institution between January 2006 and June 2011. The risk factors for postoperative complications of LADG were evaluated by univariate and multivariate analyses. RESULTS In univariate analysis of overall postoperative complications, there were significant effects of age (above 65 years), obesity (a body mass index above 25 kg/m(2)), comorbidity, cerebrovascular disease, heart disease, hypertension, diabetes mellitus, and combined comorbidities (three or more). Multivariate analysis of these risk factors showed that old age (P=.006), obesity (P<.001), and heart disease (P=.014) were independent risk factors for postoperative complications. Univariate analysis showed that obesity also had a significant effect on severe postoperative complications. CONCLUSIONS Older age, obesity, and heart disease are risk factors for postoperative complications after LADG. Greater caution or more limited surgery is required to reduce the high rate of complications in patients with these risk factors.

A prospective feasibility and safety study of laparoscopy-assisted distal gastrectomy for clinical stage I gastric cancer initiated by surgeons with much experience of open gastrectomy and laparoscopic surgery. Gastric Cancer 2013; 16:126-32. [PMID: 22527185 DOI: 10.1007/s10120-012-0157-2] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2011] [Accepted: 04/01/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND The aim of this prospective study was to evaluate the feasibility and safety of laparoscopy-assisted distal gastrectomy (LADG) initiated by surgeons with much experience of open gastrectomy and laparoscopic surgery. METHODS Three surgeons who each had experience with more than 300 cases of open gastrectomy, more than 100 cases of laparoscopic cholecystectomy, more than 5 cases of laparoscopic colectomy, and more than 5 cases of laparoscopic partial gastrectomy were nominated as LADG operators. All three operators received training for LADG with study materials including videotapes, a box simulator, and an animal laboratory, with lectures and assistance from LADG instructors who each had experience of more than 50 LADG operations. Then the nominated LADG operators performed LADG with the instructors, in which their skills were evaluated and certified. Thereafter, they performed LADG without assistance from the instructors. The target of this study was clinical stage I gastric cancer that was resectable by distal gastrectomy. D1 + alpha, D1 + beta, or D2 dissection was performed laparoscopically. Basically reconstruction was done extracorporeally with a Billroth-I gastroduodenostomy. An extramural review board checked the surgical quality of the operations performed by the three surgeons. The primary endpoint was morbidity and mortality. RESULTS A total of 193 patients were enrolled in this study between August 2004 and July 2009. The median blood loss was 35 ml and the median operation time was 250 min. Conversion to open surgery was seen in 6 patients; 4 due to bleeding and 2 due to advanced disease. Overall morbidity was 1.6 %, including grade 2 anastomotic leakage in 0.5 % and grade 2 pancreatic fistula in 0.5 %. No mortality was observed. The number of cases required until the LADG operators acted as LADG surgeons without an instructor was 3 for each of the three surgeons. When comparing the data between that in the training period (n = 9) and the operators' data (n = 174), the median operation time was significantly longer in the training period (355 min) than in the latter period (247.5 min) (p = 0.015). Median blood loss was also greater in the training period (150 ml) than the latter period (32.5 ml), but the difference did not reach statistical significance (p = 0.084). During the training period, no patient developed any complications of ≥ grade 2. CONCLUSION These results suggested that LADG could be initiated and performed feasibly and safely if surgeons with much experience of open gastrectomy and laparoscopic surgery received adequate training for LADG.

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 The use of laparoscopy-assisted distal gastrectomy (LADG) in advanced gastric cancer (AGC) remains a controversial topic, mainly because of doubts about its oncologic validity. To date, literature on the prognosis for AGC after LADG is scarce. This study evaluated the procedure's long-term benefits compared with those of the conventional, open distal gastrectomy (ODG). METHODS This study involved 201 patients, 66 of whom underwent LADG, with a mean follow-up period of 49.2 months, from January 1999 to March 2010. A clear set of criteria was used to select patients (including no evidence of lymph node metastasis) and surgeons (subject to their experience). Survival outcomes were assessed by Kaplan-Meier analysis and log-rank testing. The postoperative recovery and complications of the patients also were monitored. RESULTS No significant difference was observed between LADG and ODG in terms of overall survival or disease-specific survival. The corresponding 5-year survival rates for individual tumor node metastasis stages also were comparable in each group. The number of lymph nodes harvested was similar in the two groups, although the operation time was significantly shorter for ODG. The postoperative hospital stay was shorter for LADG patients (average stay of 8.4 vs. 18.1 days in the ODG group; p < 0.001), and the postoperative complication rate was almost half that for ODG (13.6 vs. 25.0 %; p = 0.048). CONCLUSION The combination of the long- and short-term data indicates that LADG should be considered as a feasible alternative to ODG for the treatment of AGC. Its widespread integration requires the accumulation of similar results across multiple centers worldwide.

Abstract
BACKGROUND Obesity is known to be a preoperative risk factor for gastric cancer surgery. However, the influence of obesity on laparoscopy-assisted distal gastrectomy (LADG) remains controversial. In the present study, we evaluated several obesity parameters and investigated the influence of obesity on the surgical outcomes of LADG for gastric cancer. MATERIALS AND METHODS Between January 2010 and July 2011, 84 patients who underwent LADG for gastric cancer were enrolled. Visceral fat area (VFA) and subcutaneous fat area (SFA) were measured in cross-sectional CT scan using SlimVision(®) software. Patients were classified into two groups by the degree of BMI or VFA. Surgery time and blood loss were compared between each two groups. Predictive factors for perioperative complications were assessed by univariate and multivariate analyses. RESULTS There were no significant differences in surgery time or blood loss between patients with high and low BMIs. In contrast, high VFA patients had significantly longer surgery times (p=0.0047) and higher estimated blood loss (p=0.0034) than low VFA patients. By univariate and multivariate analyses, only a high VFA significantly predicted perioperative complications (p=0.0162, p=0.0288). CONCLUSIONS We suggest that VFA is more accurate than BMI in predicting surgery time, blood loss, and perioperative complications associated with LADG for gastric cancer. The visceral fat area could be efficiently assessed before laparoscopic surgery for gastric cancer in obese patients.

Abstract
PURPOSE We aimed at investigating the efficacy of multidetector computed tomography (MDCT) angiogram reconstructed using the maximum intensity projection (MIP) technique for the assessment of perigastric vascular anatomy before laparoscopy-assisted gastrectomy (LAG) for gastric cancer. METHODS Seventy-one patients who underwent LAG were enrolled in the study. Contrast-enhanced scans of the portal venous phase were performed by a MDCT scanner. The CT images were reconstructed using thin-slab MIP. The anatomic variations in the inflow and the location of the left gastric vein (LGV) were detected. The patterns of perigastric arterial origins were divided according to Michels' classification. The intraoperative blood loss on LAG was compared before and after MDCT angiography was introduced in the study. RESULTS The LGV flowed into the portal vein in 31 patients; the splenic vein, 25 patients; and the junction of these two veins, 15 patients. The LGV passed to the dorsal and ventral sides of the common hepatic artery in 30 and 13 patients and to the dorsal and ventral sides of the splenic artery in 8 and 20 patients, respectively. Michels' type II was found in one patient; type V, in three patients; and type VI, in two patients. The LGV location detected by MDCT was confirmed during surgery in all cases. Intraoperative blood loss after introduction of the MDCT angiography was significantly less than that before its introduction (p = 0.0032). CONCLUSIONS An MDCT angiogram reconstructed using the MIP technique is effective for assessing the perigastric vascular anatomy before LAG for gastric cancer.

Abstract
The laparoscopic surgery in gastric cancer is applied with increasing frequency nowadays; noticeable reports come mainly from Korea and Japan with satisfactory results. This review presents briefly the issue by evaluating its role. A PubMed search of relevant articles published up to 2010 was performed to identify current information. Most data come from Far East, where gastric cancer occurs more often, and the proportion of early gastric cancer is high. Laparoscopic approach includes both the diagnostic laparoscopy and laparoscopic resection. Laparoscopic gastrectomy has currently limited application for gastric cancer in the West; it is not widely accepted and raises important considerations necessitating the planning of multicentre randomised control trials based mainly on the long-term results.

Abstract
BACKGROUND Whether laparoscopy with CO(2) pneumoperitoneum affects the peritoneal metastasis of gastric cancer is a pressing question. In light of the important impact change in peritoneal macrophage function has on the peritoneal metastasis of gastric cancer, this study investigated the change in peritoneal macrophage function in gastric cancer in the CO(2) pneumoperitoneum environment, as well as its effect on the peritoneal metastasis of gastric cancer. METHODS An orthotopic transplantation model of murine forestomach carcinoma was established using the 615 mouse line. The mice bearing tumors were randomly divided into four groups (30 mice each group): anesthesia alone, laparotomy, mini-laparotomy, and CO(2) insufflation. After the operation, peritoneal macrophages were collected from 6 mice in each group and cultured. The phagocytosis of neutral red by macrophages and the levels of NO, TNF-α, IL-10, and VEGF produced by macrophages were measured after 12, 24, 48, and 72 h of culture. The remaining mice were observed after 2 weeks for the rate of peritoneal metastasis of forestomach carcinoma cells and the total weight of implanted nodules. RESULTS In the laparotomy group, 4 mice died intraoperatively and 2 died in the CO(2) insufflation group. The uptake of neutral red by peritoneal macrophages and the levels of NO, TNF-α, IL-10, and VEGF secreted by peritoneal macrophages in the laparotomy group and mini-laparotomy group after 12 h of culture were all significantly higher than those in the anesthesia-alone group (p < 0.05). The corresponding levels in the CO(2) insufflation group after 12 h were all significantly lower than those in the anesthesia-alone group (p < 0.05). There were no significant differences among the four groups at 24, 48, and 72 h after culture. Comparing with those in the laparotomy group, the uptake of neutral red by peritoneal macrophages and the levels of NO, TNF-α, IL-10, and VEGF secreted by peritoneal macrophages in the CO(2) insufflation group were all significantly lower after 12 h of culture (p < 0.05), but did not differ significantly at 24, 48, and 72 h of culture (p > 0.05), and did not differ significantly in the mini-laparotomy group at all the time (p > 0.05). The rate of peritoneal metastasis of mouse forestomach carcinoma was 50% in the laparotomy group, 45.83% in the mini-laparotomy group, and 45.45% in the CO(2) insufflation group; this difference was not statistically significant (p > 0.05). The total weight of implanted nodules of mouse forestomach carcinoma was 1.02 ± 0.38 g in the laparotomy group, 0.97 ± 0.41 g in the mini-laparotomy group, and 0.93 ± 0.45 g in the CO(2) insufflation group, which was not a statistically significant difference (p > 0.05). CONCLUSION CO(2) pneumoperitoneum neither significantly changes the phagocytosis and cytokine secretion functions of peritoneal macrophages in gastric cancer-bearing mice nor significantly promotes peritoneal metastasis of gastric cancer.

Abstract
To evaluate the usefulness of laparoscopic assistance for curative distal gastrectomy by minilaparotomy, 19 patients (body mass index < or = 25.0 kg/m2) with T1NO-1 gastric cancer who underwent distal gastrectomy with a minilaparotomy (skin incision < or = 7 cm) with laparoscopic assistance (LA (+) group) were compared with 19 historic controls who underwent equivalent surgery by minilaparotomy without laparoscopic assistance (LA (--) group). The percentage of patients with blood loss more than 300 mL tended to be lower in the LA (+) group (5.3% versus 31.6%, P = 0.09). The first flatus passage was earlier (P = 0.04), serum C-reactive protein levels on postoperative day 1 were lower (P = 0.04), and white blood cell counts on postoperative day 1 tended to be lower (P = 0.07) in the LA (+) group. Minilaparotomy with laparoscopic assistance seems to be less invasive compared with pure minilaparotomy. This procedure is considered to be a simple alternative to standard laparoscopic-assisted distal gastrectomy in selected patients with T1NO-1 gastric cancer.

Abstract
Gastric cancer is most common cancer in Korea. Surgery is still the main axis of treatment. Due to early detection of gastric cancer, the innovation of surgical instruments and technological advances, gastric cancer treatment is now shifting to a new era. One of the most astonishing changes is that minimally invasive surgery (MIS) is becoming more dominant treatment for early gastric cancer. These MIS are represented by endoscopic resection, laparoscopic surgery, robotic surgery, single-port surgery and natural orifice transluminal endoscopic surgery. Among them, laparoscopic gastrectomy is most actively performed in the field of surgery. Laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer (EGC) has already gained popularity in terms of the short-term outcomes including patient's quality of life. We only have to wait for the long-term oncologic results of Korean Laparoscopic Gastrointestinal Surgery Study Group. Upcoming top issues following oncologic safety of LADG are function-preserving surgery for EGC, application of laparoscopy to advanced gastric cancer and sentinel lymph node navigation surgery. In the aspect of technique, laparoscopic surgery at present could reproduce almost the whole open procedures. However, the other fields mentioned above need more evidences and experiences. All these new ideas and attempts provide technical advances, which will minimize surgical insults and maximize the surgical outcomes and the quality of life of patients.

Abstract
OBJECTIVE To evaluate the effectiveness of totally laparoscopic distal gastrectomy with gastroduodenostomy (TLDG), we compared its early surgical outcomes with those of laparoscopy-assisted distal gastrectomy with gastroduodenostomy (LADG). METHODS We retrospectively analyzed early surgical outcomes in 567 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2009 and March 2010. The patients were divided into those with underwent TLDG and those with underwent LADG. Their surgical outcomes were analyzed according to the WHO Asia-Pacific Obesity classification. RESULTS In overall patients, TLDG showed the significant results of early surgical outcomes. But more importantly, in the analysis of early surgical outcomes for obese patients, we found that TLDG could improve overall complication rate (p = 0.031), time to first flatus (p = 0.009), time to commencement of soft diet (p < 0.001), administration of analgesics (p = 0.019), pain score (Numeric Rating Scale, NRS), and hospital discharge (p = 0.003). CONCLUSIONS We suggested that TLDG contributes to the improvement of early surgical outcomes. We further suggest that TLDG in obese patients could be the best way to improve early surgical outcomes, including the bowel movement, pain score, overall complication rate, and hospital discharge.

Distal gastrectomy via minilaparotomy for non-overweight patients with T1N0-1 gastric cancer: initial experience of 30 cases. Int J Surg 2010; 8:643-7. [PMID: 20713190 DOI: 10.1016/j.ijsu.2010.07.302] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2010] [Revised: 07/13/2010] [Accepted: 07/25/2010] [Indexed: 11/21/2022]
Abstract
Minilaparotomy is considered to be a useful treatment alternative to laparoscopic-assisted surgery from the viewpoint of minimal invasiveness, although it has several limitations for the resection of malignant tumors. We evaluated the usefulness of distal gastrectomy via minilaparotomy for non-overweight patients with clinically diagnosed T1N0-1 gastric cancer. Clinicopathological and surgical data on 30 patients attempted to undergo distal gastrectomy via minilaparotomy (skin incision, ≤7cm) without laparoscopic assistance were analyzed. Inclusion criteria were clinically (preoperatively) diagnosed T1N0-1 gastric cancer that was not suitable for endoscopic mucosal resection located in the middle- or lower-third of the stomach and the patient body mass index ≤ 25.0 kg/m(2). The minilaparotomy approach was successful in 27 patients (90%), while laparoscopic assistance was required to accomplish the procedures in three patients (10%). The type of lymph node dissection was D1 + α in 23 patients and D1 + β in 7 patients. The duration of surgery was 105-170 min (median, 143.5 min) and blood loss was 25-520 mL (median, 152.5 mL). Pathological stage was stage IA in 26 patients, IB in two patients, and stage II in two patients. Postoperative complications were wound infection in one patient, bleeding in one patient, and anastomotic ulcer in one patient. The length of postoperative stay was 7-41 (median, 11) days. With a median follow-up of 31 months, there was no recurrence. Distal gastrectomy via minilaparotomy seems feasible and safe in the majority of non-overweight patients with clinically diagnosed T1N0 gastric cancer.

Laparoscopy-assisted pancreas- and spleen-preserving total gastrectomy for gastric cancer as compared with open total gastrectomy. Surg Endosc 2009; 23:2416-23.

Abstract
BACKGROUND Laparoscopy-assisted total gastrectomy (LATG) is not widely used for the treatment of gastric cancer located in the upper or middle third of the stomach. To assess the safety and usefulness of LATG, we compared the outcomes of LATG with those of open total gastrectomy (OTG). METHODS From July 2004 to July 2007, we performed pancreas- and spleen-preserving total gastrectomy with D1 + beta or D2 lymph-node dissection and Roux-en-Y reconstruction in 74 patients with cancer located in the upper or middle third of the stomach. Of these patients, 30 underwent LATG (LATG group) and 44 underwent OTG (OTG group). Short-term outcomes were compared between the groups. RESULTS Operation time was significantly longer in the LATG group than in the OTG group (313 min vs. 218 min, p < 0.001). Blood loss (134 g vs. 407 g, p < 0.001) and the rate of the use of analgesics (6.8 times vs. 11.8 times, p < 0.05) were significantly lower, and postoperative hospital stay was significantly shorter in the LATG group than in the OTG group (13.5 days vs. 18.2 days, p < 0.05). The LATG group had better hematologic and serum chemical profiles, including white-cell counts, C-reactive protein levels, total protein levels, and albumin levels, as well as lower rate of postoperative body-weight loss. The number of dissected lymph nodes (43.2 vs. 51.2, p = 0.098) and the rate of postoperative complications (20.0% vs. 27.3%, p = 0.287) were similar in the groups. However, major complications such as anastomotic leakage, abdominal abscess, and pancreatic leakage occurred in six patients (13.6%) in the OTG group, but in none of the patients in the LATG group. CONCLUSIONS LATG is associated with less severe complications and better postoperative quality of life than OTG. We believe that LATG is a safe, useful, and less invasive alternative for the treatment of gastric cancer located in the upper or middle third of the stomach.

Abstract
BACKGROUND Some studies have found high incidences of intraoperative and postoperative complications for patients with gastric cancer. To determine the predictive factors for the surgical complications of laparoscopic gastric surgery, surgical outcomes were evaluated. METHODS Between April 2002 and December 2007, 152 patients with preoperatively diagnosed early gastric cancer who underwent laparoscopy-assisted distal gastrectomy (LADG) were enrolled. Visceral (VFA) and subcutaneous fat areas (SFA) were assessed by Fat Scan software. The predictive factors for surgical complications of LADG were evaluated by univariate and logistic regression analyses. RESULTS Of 152 patients, conversion to open surgery due to uncontrollable bleeding was observed in nine male patients, and postoperative complications were detected in seven male and one female patient (four anastomotic leakage, two intraabdominal abscess, one pancreatic fistula, and one lymphorrhea). High body mass index (BMI) and high VFA independently predicted conversion to open surgery and postoperative complications. VFA was significantly higher, operation time was longer, blood loss was greater, and SFA was lower in male than in female patients, whereas no significant difference was observed in BMI between male and female patients. CONCLUSIONS High BMI and high VFA can predict technical difficulties during laparoscopic gastric surgery and postoperative complications. Particularly, LADG should be performed cautiously to prevent surgical complications for male patients with high VFA. Predictive impact of VFA should be further determined in a larger set of patients.

Abstract
An assessment of the learning curve of laparoscopy-assisted distal gastrectomy (LADG) might encourage its worldwide spread among inexperienced surgeons. One hundred sixty-seven patients with early gastric cancer were enrolled in this study: 67 underwent conventional open distal gastrectomy and 100 underwent LADG after classification into 5 groups of 20 according to the surgeon's level of experience. Patient characteristics and operative findings were compared between groups. Operation time was significantly longer, time to first flatus earlier, and blood loss reduced in the LADG groups compared with the open distal gastrectomy group. Surgeons with experience of 60 cases performed operations of similar times in both groups, and blood loss decreased with experience of 20 cases. There was no operative conversion, the frequency of nonsteroidal anti-inflammatory drugs administered were significantly less, and length of hospital stay were shorter by surgeons with experience of 60 cases. LADG is a technically feasible surgical procedure, depending on the surgeon's technical proficiency. Experience of at least 60 cases of LADG seems to result in satisfactory patient outcomes.

Abstract
BACKGROUND Laparoscopy-assisted gastrectomy (LAG) is being increasingly performed in Japan. However, the indication of LAG in elderly patients who usually have preoperative morbidities and reduced functional capacities still remains unclear. MATERIALS AND METHODS Two hundred eighty-nine patients who underwent LAG at the Cancer Institute Hospital were included in this study. Among them, 240 cases were younger than 75 years old (Y-LAG group), and 49 cases were 75 years old or older (E-LAG group). Early surgical outcomes between the two groups were compared to clarify the feasibility of performing LAG in elderly patients. RESULTS The E-LAG group had a higher incidence of preoperative morbidities; however, the frequency of intraoperative and postoperative complications in this group was not significantly different from the Y-LAG group (9% vs 11%). The operation time was significantly shorter, and the number of retrieved lymph nodes was significantly smaller in the E-LAG group compared to the Y-LAG group. However, other early surgical outcomes were not significantly different between two groups. CONCLUSIONS LAG proved to be a feasible and safe procedure in elderly patients provided that the patients were selected carefully.

Abstract
BACKGROUND AND AIM Laparoscopy-assisted distal gastrectomy (LADG) has not yet been widely adopted for the treatment of gastric cancers because of the perceived complexity of the procedure. In addition to the proficiency of the operator, other factors could potentially be optimized to improve postoperative outcomes. The aim of this study was to evaluate a standardized operative procedure for assistants performing LADG. MATERIALS AND METHODS Of 114 patients, 64 initially underwent conventional LADG (CLDG) and then 50 underwent standardized procedure (SLDG) in which the role of assistant in LADG was completely established. Parameters compared for the SLDG and CLDG groups were operation time, estimated blood loss, intra- or postoperative complications, preservation of the vagus nerve, and the number of pathologically examined lymph nodes. RESULTS The operation time for the SLDG procedure (mean +/- SE, 229 +/- 6 min) was shorter than for the CLDG procedure (261 +/- 8 min; P < 0.002), and the estimated blood loss for SLDG (57 +/- 7 ml) was less than for CLDG (108 +/- 17 ml, P < 0.004). The celiac branch of the vagus nerve was preserved in 73% of SLDG patients compared with 52% of CLDG patients (P < 0.03). More lymph nodes were pathologically examined in SLDG patients (38.3 +/- 1.5) than in CLDG patients (32.5 +/- 1.8, P = 0.02). CONCLUSIONS Standardization of the LADG procedure for assistants enabled a shorter operation time, reduced blood loss, a higher rate of vagus nerve preservation, and more accurate lymph node dissection.

Abstract
BACKGROUND Laparoscopy-assisted gastrectomy (LAG) is increasingly performed in Japan by a number of surgeons. As this is a relatively new technique, a training system is important, however there has been little discussion about an educational system for teaching trainees to perform LAG and the ideal training system has not yet been established. PATIENTS AND METHODS Two hundred and sixty-three patients who underwent LAG at the Cancer Institute Hospital were included in this study. In all cases there was standardization of LAG (the way in which the surgical field was formed by the assistant and the way the operator dissected the lymph nodes was determined and all cases were performed using the same laparoscopic procedures) and a step-by-step training system was completed. Specialists performed the surgery in 213 patients (S group) while the remaining 50 patients had their surgery performed by trainees (T group). Early surgical outcomes were compared between specialists and trainees to clarify whether the standardization and our educational system are useful in maintaining the quality of LAG. RESULTS T-group patients had significantly longer operation times than those of S-group (262.3 +/- 7.3 versus 233.3 +/- 3.7 min), however, the trainees reached the plateau of their learning curve earlier than previously reported. All other early surgical outcomes examined, including intraoperative blood loss (76.7 +/- 35.1 versus 64.9 +/- 7.7 ml), number of retrieved lymph nodes (33.4 +/- 1.4 versus 35.7 +/- 0.8), morbidity (8 versus 14%), and mortality (0% in both groups), were not significantly different between the two groups. CONCLUSION The surgical results of T-group were almost equal to those of S-group, showing that our educational system is effective and surgical quality is maintained. Standardized laparoscopic procedures and sufficient intensive experience in the short term are requisites for effectively learning how to perform LAG.

Abstract
BACKGROUND This article reviews the evidence on the safety and efficacy of minimally invasive surgery for gastric and oesophageal cancer. METHODS An electronic search of the literature between 1997 and 2007 was undertaken to identify primary studies and systematic reviews; studies were retrieved and analysed using predetermined criteria. Information on the safety and efficacy of minimally invasive surgery for gastric and oesophageal cancer was recorded and analysed. RESULTS From 188 abstracts reviewed, 46 eligible studies were identified, 23 on oesophagectomy and 23 on gastrectomy. There were 35 case series, eight case-matched studies and three randomized controlled trials. Compared with the contemporary results of open surgery, reports on minimally invasive surgery indicate potentially favourable outcomes in terms of operative blood loss, recovery of gastrointestinal function and hospital stay. However, the quality of the data was generally poor, with many potential sources of bias. CONCLUSION Minimally invasive surgery is feasible but evidence of benefit is currently weak.

Abstract
BACKGROUND The data are scarce on the outcome for elderly patients presenting with resectable gastric cancer in the West who have been treated with minimally invasive surgery. This report presents the authors' early experience with totally laparoscopic gastric resections for cancer in elderly patients. METHODS A total of 20 patients underwent laparoscopic gastrectomy procedures: 14 distal, 5 subtotal, and 1 total gastrectomy. The male-to-female ratio was 15 to 5. The ages ranged from 75 to 88 years (mean, 80 years). RESULTS All cases were managed laparoscopically with R0 resection. Four patients needed high-dependency unit care postoperatively. There were no perioperative deaths. The median time required for the procedure was 212 min, and time to diet was 4 days. The hospital stay was 8 days. Four patients experienced significant complications, with two patients requiring reoperation. The pathology was adenocarcinoma for 17 patients and high-grade dysplasia for 3 patients. CONCLUSION Among elderly patients for whom conventional gastric surgery carries a high morbidity and mortality risk, minimal access surgery may offer equivalent oncologic integrity but with superior safety and economy. The primary aim is to remove the tumor with at least a D1 lymphadenectomy.

Abstract
BACKGROUND The aim was to conduct a systematic review of the literature on the subject of laparoscopic gastrectomy (LG) and determine the relative merits of laparoscopic (LG) and open gastrectomy (OG) for gastric carcinoma. MATERIAL AND METHODS A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified individual retrospective and prospective series on LG (proximal, distal and total). Furthermore, all clinical trials that compared LG and OG published in the English language between January 1990 and the end of December 2006 were also identified. A large number of outcome variables were analysed for individual series and comparative trials between LG and OG and results discussed and tabulated. RESULTS The majority of the literature is published from Japan showing both oncological adequacy and safety of LG. The majority of early series and comparative studies have utilized laparoscopic resection for early and distal gastric cancer. However, with increasing advanced laparoscopic experience, advancement in digital technology and improvement in instrumentation, more advanced gastric cancers and more extensive procedures such as laparoscopic-assisted total gastrectomy and laparoscopy-assisted D2 dissection are becoming more common. To date lymph node harvesting, resection margins and complication rates seem to be equivalent to open procedures. Furthermore, the earlier fears of port-site metastases have not been borne out. CONCLUSIONS The available data suggests that LG seems to be associated with quicker return of gastrointestinal function, faster ambulation, earlier discharge from hospital, and comparable complications and recurrence rate to OG. However, the operating time for LG remains significantly longer compared to its open counterpart, although with experience it is achieving parity with OG. However, the majority of the comparative trials (if not all) probably do not have the power to detect differences in the outcome. As far as the RCT's (LG vs. OG) are concerned, the numbers of patients in such trials are small and the majority of patients were operated upon for early distal gastric cancer and, therefore, any meaningful conclusions regarding the advantages or disadvantages of LG for both the ECGs and extensive and advanced gastric tumours are difficult to justify.

Surg Endosc 2007; 21:1582-7. [PMID: 17479340 DOI: 10.1007/s00464-006-9133-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2006] [Revised: 08/19/2006] [Accepted: 10/09/2006] [Indexed: 12/18/2022]
Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) for gallbladder carcinoma still is controversial except for the early stages of gallbladder carcinoma (Tis). This study was designed to evaluate and revisit the role of LC in treating gallbladder carcinoma. METHODS Available medical records of patients with surgeries for gallbladder carcinoma were retrospectively investigated from August 1992 to February 2005. RESULTS Among 219 patients treated for gallbladder carcinoma, 57 (26%) underwent LC. A total of 16 patients (28.1%) underwent subsequent radical cholecystectomy (LC-RC), and 41 (71.9%) were only followed up without radical surgery (LC). Tis was found in 11 patients (19.3%), T1a in 3 patients (5.3%), T1b in 8 patients (14%), T2 in 19 patients (33.3%), and T3 in 16 patients (28.1%). The findings showed R0 in 14 cases of the radical cholecystectomy group, and clinical R0 was noted in 30 cases of the LC-only group. No survival differences were noted between LC and LC-RC (p = 0.2575), especially in the case of T2 lesions (p = 0.6274), nor between the R0 and clinical R0 (p = 0.5839). However, significant survival differences were noted between the R2 and R0 groups, and between R2 and clinical R0, respectively (p < 0.001). CONCLUSIONS The findings show that LC could be appropriate treatment for gallbladder carcinoma only in selected cases of clinical R0 lesions.

Abstract
AIM Recently, LADG has become a viable alternative for the treatment of patients with early gastric cancer. Surgeons who are seeking to undertake, or currently practicing LADG, are concerned about unpredictable intraoperative events that occur during LADG. The aims of this study were to investigate intraoperative and postoperative complications in laparoscopy-assisted distal gastrectomy (LADG) with more than D1+beta lymphadenectomy for gastric cancer. MATERIALS AND METHODS Of 219 patients who underwent laparoscopy-assisted gastrectomy for gastric cancer by a single surgeon between April 2003 and January 2006, 128 patients were enrolled in this study. The operative procedure was divided into five steps. Various intraoperative complications, such as bleeding and perigastric organ injuries, that occurred during different operative steps were investigated by reviewing videotapes. RESULTS A total of 839 events of bleeding were encountered during the procedure with a mean of 6.6 per patient. The mean number of bleeding during each step was significantly different and more bleedings occurred during steps II and IV (P<0.0001). Sixteen cases of complications other than bleeding occurred in 15 patients (11.7%), and they were all managed properly without conversion or reoperation. Postoperative morbidity and mortality rates were 15.6 and 0.7%, respectively. CONCLUSION LADG with more than D1+beta lymphadenectomy is a technically feasible and acceptable surgical modality for gastric cancer. Intraoperative bleeding was found to be the most common complication during LADG for gastric cancer, and more bleedings occurred during steps II and IV.
