Equal short-term outcomes of intracorporeal mechanical gastrogastrostomy in laparoscopic pylorus-preserving gastrectomy for cT1N0 gastric cancer in the middle stomach compared with the extracorporeal hand-sewing method. Surg Endosc 2024; 38:3115-3125. [PMID: 38619559 DOI: 10.1007/s00464-024-10823-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 03/22/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND Intracorporeal mechanical gastrogastrostomy (IMG) techniques have recently been developed and their short-term safety was presented in their initial evaluation. However, whether they are comparable to extracorporeal hand-sewing gastrogastrostomy (EHG) remains unclear. The aim of the study is to establish the safety of IMG in totally laparoscopic pylorus-preserving gastrectomy (TLPPG) compared to EHG in laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG). METHODS We retrospectively analyzed the short-term outcomes of patients with middle-third early gastric cancer who underwent LAPPG or TLPPG between 2005 and 2022. The primary objective of this study was to evaluate the non-inferiority of IMG to EHG in terms of safety, with the primary endpoint being the risk difference in anastomosis-related complications (ARCs). The sample size required to achieve a statistical power of 80% for the non-inferiority test was 971 with a one-sided alpha level of 5% and non-inferiority of 5%. RESULTS The analysis included a total of 1,021 patients who underwent LAPPG or TLPPG during the study period. Among them, 488 patients underwent EHG, while 533 underwent IMG. The incidences of ARCs were 11.3% and 11.4% in EHG and IMG, respectively. The observed difference in incidence was 0.0017 (90% confidence interval - 0.0313 to 0.0345), which statistically demonstrated the non-inferiority of IMG to EHG in the incidence of ARCs. Among other complications, the incidence of wound infection in IMG was lower than that in EHG. CONCLUSION IMG is safe regarding ARCs compared with EHG. These results will encourage surgeons to introduce IMG for patients with early middle gastric cancer.

Abstract
BACKGROUND To investigate the short-term and long-term outcomes of preserving the celiac branch of the vagus nerve during laparoscopic distal gastrectomy. METHODS A total of 149 patients with prospective diagnosis of gastric cancer who underwent laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-II anastomosis and D2 lymph node dissection between 2017 and 2018 were retrospectively analyzed. The patients were divided into the preserved LADG group (P-LADG, n = 56) and the resected LADG group (R-LADG, n = 93) according to whether the vagus nerve celiac branch was preserved. We selected 56 patients (P-LADG, n = 56) with preservation of the celiac branch of the vagus nerve and 56 patients (R-LADG, n = 56) with removal of the celiac branch of the vagus nerve by propensity-matched score method. Postoperative nutritional status, weight change, short-term and long-term postoperative complications, and gallstone formation were evaluated in both groups at 5 years of postoperative follow-up. The status of residual gastritis and bile reflux was assessed endoscopically at 12 months postoperatively. RESULTS The incidence of diarrhea at 5 years postoperatively was lower in the P-LADG group than in the R-LADG group (p < 0.05). In the multivariate logistic analysis, the removal of vagus nerve celiac branch was an independent risk factor for the occurrence of postoperative diarrhea (odds ratio = 3.389, 95% confidential interval = 1.143-10.049, p = 0.028). In the multivariate logistic analysis, the removal of vagus nerve celiac branch was an independent risk factor for the occurrence of postoperative diarrhea (odds ratio = 4.371, 95% confidential interval = 1.418-13.479, p = 0.010). CONCLUSIONS Preservation of the celiac branch of the vagus nerve in LADG reduced the incidence of postoperative diarrhea postoperatively in gastric cancer. TRIAL REGISTRATION This study was registered with the Ethics Committee of the First Affiliated Hospital of Dalian Medical University in 2014 under the registration number: LCKY2014-04(X).

Abstract
Background Delayed gastric emptying (DGE) after distal gastrectomy impacts patients’ nutritional status and quality of life. The current treatments of DGE seem unsatisfactory or need invasive interventions. It is unknown whether transcutaneous electroacupuncture (TEA) is effective in treating DGE. Methods A total of 90 eligible participants who underwent distal gastrectomy will be randomly allocated to either the TEA group (n = 60) or the sham transcutaneous electroacupuncture (sham-TEA) group (n = 30). Each participant will receive TEA on the bilateral acupoints of Zusanli (ST36) and Neiguan (PC6) for 4 weeks. The primary outcomes will be the residual rates of radioactivity in the stomach by gastric scintigraphy and total response rates. The secondary outcomes will be endoscopic features, autonomic function, nutritional and psychological status, serum examination, and quality of life (QoL). The adverse events will also be reported. The patients will be followed up 1 year after the treatment. Discussion The findings of this randomized trial will provide high-quality evidence regarding the efficacy and safety of long-term TEA for treating DGE after distal gastrectomy.

Abstract
Simple Summary For patients with early gastric cancer (EGC), a good prognosis is achieved by conventional standard gastrectomy with radical lymphadenectomy. However, postgastrectomy syndrome is often inevitable and results in decreased quality of life (QOL). To improve patients’ QOL, proximal gastrectomy instead of total gastrectomy and pylorus-preserving gastrectomy instead of distal gastrectomy have been widely accepted as function-preserving gastrectomies. Recently, personalized, minimized gastrectomy with sentinel node navigation surgery has been developed and is expected to be an ideal treatment option for patients with EGC. Herein, we review the indications, surgical techniques, and postoperative outcomes of function-preserving gastrectomy. Abstract Recently, minimally invasive (endoscopic or laparoscopic) treatment for early gastric cancer (EGC) has been widely accepted. However, a standard gastrectomy with radical lymphadenectomy is generally performed in patients with EGC who have no indications for endoscopic resection, and postgastrectomy dysfunction is one of the problems of standard gastrectomy. Function-preserving gastrectomy, such as proximal gastrectomy and pylorus-preserving gastrectomy, can be considered when attempting to preserve the patient’s quality of life (QOL) postoperatively. In addition, sentinel node navigation surgery for EGC has been applied in clinical practice in several prospective studies on function-preserving personalized minimized gastrectomy. In the near future, the sentinel lymph node concept is expected to form the basis for establishing an ideal, personalized, minimally invasive function-preserving treatment for patients with EGC, which will improve their postoperative QOL without compromising their long-term survival. In this review article, we summarize the current status, surgical techniques, and postoperative outcomes of function-preserving gastrectomy for EGC.

Abstract
BACKGROUND AND AIM This study aimed to investigate the postoperative quality of life (QOL) between laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) and laparoscopy-assisted distal gastrectomy with Billroth I anastomosis (LADGBI) in patients with middle-third early gastric cancers (EGC). METHODS From January 2015 to August 2017, a total 91 patients with EGC underwent LAPPG or LADGBI procedure with complete QLQ-C30 and QLQ-STO22 in Ren Ji Hospital. Not only do surgical and oncological safety as well as clinicopathologic characteristics analyze, but also chronological changes of QOL and nutritional status were compared for the evaluation of functional advantages. RESULTS There was no significant difference in clinicopathologic characteristics and perioperative recovery between LAPPG and LADGBI. During postoperative 2-year follow up, LAPPG showed significant advantages over LADGBI in emotional functioning, insomnia, appetite loss, reflux, and taste problem and presented larger area in global and functional scales and less area in symptom scales, which means that LAPPG tended to present better improvement and less symptoms than LADGBI for QOL 2 years after surgery. Furthermore, LAPPG could bring about significant improvement in total protein and hemoglobin compared to LADGBI at postoperative 2 years. CONCLUSION LAPPG obtains QOL as well as total protein and hemoglobin superiority and could be recommended to patients with EGC whose tumor located in the middle third of the stomach.

Abstract
BACKGROUND Due to better functional outcomes, pylorus-preserving gastrectomy (PPG) has been widely applied for early gastric cancer (EGC) patients as an alternative to distal gastrectomy (DG). However, controversies still persist regarding the surgical efficacy and oncological safety of PPG. METHODS Original studies comparing PPG and DG for EGC were searched in PubMed, Embase, and the Cochrane Register of Controlled Trials up to December 2019. The weight mean difference, standardized mean difference, or odds risk was used to calculate the short-term and long-term outcomes between the two groups. RESULTS Twenty-one comparative studies comprising 4871 patients (1955 in the PPG group and 2916 in the DG group) were enrolled in this systematic review and meta-analysis. PPG showed longer hospital day, decreased harvested lymph nodes, and more delayed gastric emptying. However, PPG had the benefits of lower incidence of anastomosis leakage, early dumping syndrome, gastritis and bile reflux, and better recovery of total protein, albumin, hemoglobin, and weight. No difference was found in operative time, blood loss, and overall complications. Moreover, the long-term survival and recurrence rate were similar in two groups. CONCLUSION Owing to the non-inferiority of surgery and oncology outcomes and the superiority of function outcomes in PPG, we revealed that PPG can be clinically applicable instead of DG in EGC. However, more high-quality comparative studies and randomized clinical trials would be required for further confirmation.

Abstract
BACKGROUND Pylorus-preserving gastrectomy (PPG) is a function-preserving procedure for cT1N0 gastric cancer located in the middle-third of stomach, which is currently performed through a laparoscopic approach (LPPG). PPG is sometimes associated with a crucial problem during the early postoperative course, designated gastric stasis. However, information regarding gastric stasis remains to be fully elucidated. METHODS The study included 897 patients who underwent LPPG between 2005 and 2017. Early postoperative gastric stasis (E-stasis) was defined when the following conditions were fulfilled: upper abdominal distension, remnant stomach fullness on radiography image, and period of starvation exceeding 72 h within 1 month postoperatively. To evaluate long-term outcomes of E-stasis, late postoperative food residue (L-residue) was defined as grade 2 or higher food residue endoscopically according to the RGB (residue, gastritis, bile) classification at 1 year postoperatively. Risk factors and long-term outcomes of E-stasis were retrospectively analyzed. RESULTS E-stasis was the most common complication during the early postoperative course. E-stasis occurred in 68 (7.6%) patients. Multivariate analysis identified age (≥ 61 years), DM, and postoperative intraabdominal infection as risk factors. At 1 year postoperatively, relative body weight ratio and postoperative serum albumin in the patients who experienced E-stasis was significantly lower than those in the other patients (P = 0.042 and 0.011, respectively). Of the patients who suffered from E-stasis, 42.5% experienced L-residue. CONCLUSIONS E-stasis after LPPG occurs in 7.6% of patients. Age, DM, and intraabdominal infection are significantly related to E-stasis. E-stasis is associated with poorer nutritional and functional outcomes even at 1 year postoperatively.

Abstract
Recent improvements in diagnostic techniques and national screening programs have resulted in increasing number of patients diagnosed with early gastric cancer (EGC). The low incidence rate of lymph node metastasis and excellent survival rates after surgical treatment for EGC enabled the reduction in the extent of lymphadenectomy and the range of gastric resection for function-preserving gastrectomy. Thus, the quality of life (QOL) of patients with gastric cancer (GC) in the curative stage can be maintained. Moreover, these function-preserving procedures have been widely performed by less invasive procedures, such as laparoscopic and robotic approaches. Pylorus-preserving gastrectomy (PPG) and proximal gastrectomy (PG) represent the two main function-preserving surgical procedures for GC. PPG is an alternative to distal gastrectomy (DG) for cT1 N0 EGC located in the middle part of the stomach. Preservation of the pyloric function is expected to prevent post-gastrectomy syndromes such as dumping syndrome. PG is an alternative to total gastrectomy (TG) and can thus be performed for cT1 N0 EGC located in the upper part of the stomach. Preservation of the residual stomach is expected to work as a reservoir for ingested food. The optimal reconstruction method after PG among the three most commonly performed procedures (esophagogastrostomy, jejunal interposition, and double-tract reconstruction) remains controversial. In addition to these three reconstruction methods, the novel double-flap technique (DFT) of esophagogastrostomy has gained attention recently because of its potential usefulness to prevent postoperative esophageal reflux. In this review article, we summarize the current evidence of PPG and PG with esophagogastrostomy by the DFT, focusing on postoperative nutrition and QOL.

Efficacy of Celiac Branch Preservation in Billroth-Ⅰ Reconstruction After Laparoscopy-Assisted Distal Gastrectomy. J Surg Res 2019; 245:330-337. [PMID: 31425872 DOI: 10.1016/j.jss.2019.07.074] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Revised: 07/09/2019] [Accepted: 07/19/2019] [Indexed: 12/22/2022]
Abstract
BACKGROUND The goal of the present retrospective study was to elucidate the efficacy of conserving the celiac branch (CB), which can reduce the adverse reactions of Billroth-Ⅰ (B-Ⅰ) restoration after the laparoscopy-assisted distal gastrectomy (LADG). METHODS Two hundred thirty-three patients with gastric cancer underwent B-Ⅰ reconstruction after LADG with dissection 2 lymphadenectomy from July 2005 to July 2012 and were monitored for 5 y. The patients were separated into 2 groups: celiac branch preserved (P-CB) group (n = 98) and celiac branch resected (R-CB) group (n = 135). In addition to patient information, tumor features, and surgical details, short-term and long-term variables such as bowel condition, surgical complications, and endoscopy findings were evaluated. RESULTS In short-term efficacy, the time of first flatus and liquid ingestion were slightly shorter in the P-CB group than in the R-CB group (3.84 ± 0.74 versus 4.38 ± 0.71, P = 0.0001; 5.04 ± 1.07 versus 5.67 ± 1.10, P = 0.0001). For long-term efficacy, the incidences of chronic diarrhea, gastroparesis, residual food, bile reflux, and reflux esophagitis were less in the P-CB group compare with the R-CB group (6.1% versus 22.2%, P = 0.001; 5.1% versus 17.8%, P = 0.004; 4.1% versus 17.8%, P = 0.004; 8.2% versus 17.8%, P = 0.036; 8.2% versus 17.8%, P = 0.036). Other parameters such as postoperative ileus and gallstones had a better efficacy trend in the P-CB group but did not suggestively vary among the groups. CONCLUSIONS The CB has an imperative part in the gastrointestinal motility, and celiac preservation mainly exerts long-term efficacy in patients who underwent B-I surgery with LADG.

Abstract
The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures including endoscopy and screening systems. Therefore, function-preserving gastrectomy (FPG) for EGC with the expectation of better quality of life (QOL) after surgery may be increasingly utilized, due to its association with low rate of lymph node metastasis and excellent survival and the possibility of employing less invasive procedures such as laparoscopic gastrectomy in combination. Pylorus-preserving gastrectomy (PPG) with curative intent lymph node dissection is a representative FPG that has been used in EGC, and its superiorities, indications, limitations, and survival benefits have already been reported in several retrospective studies. Laparoscopic proximal gastrectomy (LAPG) has also been employed in EGC of the upper third of the stomach; however, LAPG was found to be associated with major issues in achieving a balance between swallowing and reflux prevention. In patients with EGC in the upper third of the stomach, laparoscopy-assisted subtotal gastrectomy with a preserved, albeit very small, stomach may provide a better QOL and fewer postoperative complications. FPG is recommended as a surgical treatment for EGC if the indication is accurately diagnosed and strictly confirmed; however, these techniques in laparoscopic surgery present technical difficulties to surgeons without a certain degree of skills. Although many retrospective studies revealed the functional benefits or oncological safety with FPG, further prospective studies using large case series are necessary to reveal the value of FPG compared with the conventional procedures.

Abstract
This study investigated the incidence of gastric cancer metastasis to the lymph nodes along the infrapyloric artery (IPA), namely no. 6i, by reviewing our medical records of 348 patients who underwent complete no. 6 dissection. Metastasis to these nodes was observed in 11 (3.2 %) patients. In these patients, one huge tumor was located in the middle third and ten including two early tumors were located in the lower third; the metastasis rate in early lower-third tumors was 2.1 % and reached 19.5 % in advanced tumors. In contrast, no early middle-third gastric cancers had no. 6i metastasis. The median diameter of 6i-positive tumors was 62 (range 18-115) mm, and the distance from the distal tumor border to the pyloric ring was no more than 44 mm. Lymphadenectomy along the IPA is important for treating gastric cancer invading the antrum, but may be dispensable when performing pylorus-preserving gastrectomy for early middle-third cancer.

Abstract
Purpose The aim of this study was to evaluate the quality of life and functional emptying of J-pouch versus Roux-en-Y reconstruction after total gastrectomy for malignancy. Methods This study was designed as a prospective, nonblinded, randomized, parallel clinical trial (Trial Number: MN Ostrava, 200604). With informed consent, patients undergoing gastrectomy for malignancy were randomized to J-pouch or Roux-en-Y reconstruction. The time taken for a test semisolid meal labeled with 99mTc-sulfur colloid to exit the reconstructed parts was measured by dynamic scintigraphy 1 year after resection. Quality of life was measured using the Eypasch questionnaire at the same time as functional emptying assessment. This trial was investigator-initiated. Results In all, 72 patients were included into the study. The time taken for the test meal to exit the postgastrectomy reconstruction was 16.5±10.0 minutes (mean ± standard deviation) in the Roux-en-Y group and 89.4±37.8 minutes in the “J-pouch” group; the difference was statistically significant (P<0.001). Emptying of the J-pouch appeared to be a linear decreasing function compared to the exponential pattern seen in the Roux-en-Y group. The quality of life measurement showed scores of 106±18.8 points (mean ± standard deviation) in the Roux-en-Y group compared to 122±22.5 points in the J-pouch group; the difference was statistically significant (P=0.0016). There were no important adverse events. Conclusion After total gastrectomy, a J-pouch reconstruction empties more slowly and is associated with higher quality of life compared to Roux-en-Y reconstruction. Whether these two observations have a direct causative link remains unanswered.

Preserving infrapyloric vein reduces postoperative gastric stasis after laparoscopic pylorus-preserving gastrectomy. Langenbecks Arch Surg 2016; 402:49-56. [PMID: 27815708 DOI: 10.1007/s00423-016-1529-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2016] [Accepted: 10/18/2016] [Indexed: 12/23/2022]
Abstract
PURPOSE Laparoscopic pylorus-preserving gastrectomy (LPPG) is performed to preserve function in treating early gastric cancer. However, gastric stasis is a potential complication of LPPG that could decrease postoperative quality of life, possibly due to gastric edema of the pyloric cuff caused by venous stasis. We introduced an infrapyloric vein (IPV)-preserving LPPG (iLPPG) procedure to prevent pyloric cuff edema and thus minimize the incidence of gastric stasis and investigated the early clinical outcomes of iLPPG. METHODS We reviewed 150 patients with gastric cancer who underwent LPPG between August 2011 and June 2013 at the Cancer Institute Hospital and analyzed postoperative complications, incidence of gastric stasis (requiring starvation longer than 72 h or an invasive treatment), and transient delayed gastric emptying (TDGE). RESULTS Of the 150 patients, 56 underwent iLPPG and 94 underwent conventional LPPG without preservation of the IPV (cLPPG). Morbidity rates were 5.4% in the iLPPG group and 23.4% in the cLPPG group (P = 0.003). The incidence of both gastric stasis and TDGE was significantly lower in the iLPPG group than in the cLPPG group (0 vs. 8.5%, P = 0.03 and 0 vs. 7.4%, P = 0.046, respectively). Median postoperative stay was significantly shorter in the iLPPG group compared to the cLPPG group (9 vs. 11 days, P < 0.001, respectively). CONCLUSIONS Preservation of the IPV might prevent the incidence of postoperative gastric stasis after LPPG, resulting in a shorter postoperative stay.

Abstract
Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.

Abstract
BACKGROUND The postoperative functional advantages of a proximal gastrectomy over a total gastrectomy remain debatable. The aim of this study was to evaluate the functional outcomes of a proximal gastrectomy with jejunal interposition (PG-JI), compared with those for a total gastrectomy with Roux-en-Y esophagojejunostomy (TG-RY), in patients with early gastric cancer. METHODS Between 2007 and 2012, 65 patients underwent PG-JI and 117 underwent TG-RY for cT1 gastric cancer. Various parameters, including body weight, serum hemoglobin level, and interview-based symptoms, were prospectively evaluated in these patients. In patients who underwent PG-JI, the postoperative endoscopic findings were also assessed. RESULTS All the surgeries were performed via a laparotomy alone. During a median postoperative follow-up of 42 months (range, 12-78 months), PG-JI offered significant reductions in body weight loss (12.5 ± 5.8 vs. 17.4 ± 6.4 %, P < 0.001), serum hemoglobin decline (7.0 ± 5.7 vs. 9.7 ± 5.4 %, P = 0.002), and dumping symptoms (11 % [7/65] vs. 30 % [35/117], P = 0.003), while being associated with similar incidences of anastomotic stricture (9 % [6/65] vs. 8 % [9/117], P = 0.781), small bowel obstruction (0 % [0/65] vs. 2 % [2/117], P = 0.538), stasis symptoms (51 % [33/65] vs. 44 % [51/117], P = 0.358), and reflux symptoms (34 % [22/65] vs. 23 % [27/117], P = 0.121), compared with TG-RY. Four cases of gastric remnant cancer and no cases of endoscopic reflux esophagitis were found after PG-JI. CONCLUSIONS PG-JI has clear functional advantages over TG-RY, although it requires active surveillance for remnant gastric cancer.

Abstract
Purpose We retrospectively investigated the feasibility and clinical efficacy of balloon dilatation and subsequent retrievable stent insertion, when necessitated, for pyloric spasms after pylorus-preserving gastrectomy (PPG). Materials and Methods Forty-five patients experiencing pyloric spasms after PPG underwent fluoroscopic balloon dilations to alleviate obstructive symptoms due to delayed gastric emptying. Patients showing poor response to balloon dilation underwent subsequent retrievable stent insertion. Safety of the procedures was analyzed, and subjective symptoms and objective signs of pyloric spasms were analyzed and compared before and after treatment. Results Thirty-three patients (73.3%, 33/45) showed good response to balloon dilatation requiring no further treatment (balloon group). Conversely, 12 patients (26.7%, 12/45) showed poor or no response after balloon dilation requiring subsequent stent insertion (stent group). Balloon dilations and/or stent insertions were safely performed in all patients except one patient who suffered a transmural tear after balloon dilatation. In both groups, mean subjective symptom score was significantly improved and mean pyloric canal-to-height of the adjacent vertebral body ratio was significantly increased after the procedures (P <.05). Conclusion Balloon dilation is a safe and effective treatment for patients with pyloric spasms after PPG. In patients refractory to balloon dilations, retrievable stent placement can be a safe alternative tool.

Abstract
Recent advances in diagnostic techniques have allowed the diagnosis of gastric cancer (GC) at an early stage. Due to the low incidence of lymph node metastasis and favorable prognosis in early GC, function-preserving surgery which improves postoperative quality of life may be possible. Pylorus-preserving gastrectomy (PPG) is one such function-preserving procedure, which is expected to offer advantages with regards to dumping syndrome, bile reflux gastritis, and the frequency of flatus, although PPG may induce delayed gastric emptying. Proximal gastrectomy (PG) is another function-preserving procedure, which is thought to be advantageous in terms of decreased duodenogastric reflux and good food reservoir function in the remnant stomach, although the incidence of heartburn or gastric fullness associated with this procedure is high. However, these disadvantages may be overcome by the reconstruction method used. The other important problem after PG is remnant GC, which was reported to occur in approximately 5% of patients. Therefore, the reconstruction technique used with PG should facilitate postoperative endoscopic examinations for early detection and treatment of remnant gastric carcinoma. Oncologic safety seems to be assured in both procedures, if the preoperative diagnosis is accurate. Patient selection should be carefully considered. Although many retrospective studies have demonstrated the utility of function-preserving surgery, no consensus on whether to adopt function-preserving surgery as the standard of care has been reached. Further prospective randomized controlled trials are necessary to evaluate survival and postoperative quality of life associated with function-preserving surgery.

Abstract
BACKGROUND The three-dimensional view and articulating devices in robot system might have a benefit performing the delicate procedure of pylorus-preserving gastrectomy. This study was conducted to evaluate the feasibility and safety of robot-assisted pylorus-preserving gastrectomy (RAPPG) and to compare the perioperative outcomes and oncologic safety between RAPPG and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) for middle-third early gastric cancer. METHODS Between June 2008 and December 2013, we retrospectively collected data of 68 patients with RAPPG and propensity score matched 68 patients with LAPPG for the treatment of early gastric cancer at Seoul National University Hospital. The covariates for propensity score matching were: age, sex, American Society of Anesthesiologists score, body mass index, and operators. Clinicopathologic characteristics and surgical outcomes were compared between the two groups. RESULTS All RAPPG cases were performed successfully without open or laparoscopic conversion. Patient demographics and perioperative outcomes did not differ between the two groups except in operation time (258.3 vs. 193.9 min; P < 0.001). There was no significant difference in complication rates between the two groups (19.1 vs. 22.1 %; P = 0.671). The mean number of examined lymph nodes (33.4 vs. 36.5; P = 0.153), and the mean number of lymph nodes at each station was not different between the two groups. CONCLUSIONS RAPPG can be a safe treatment option for middle-third early gastric cancer in terms of surgical complications and oncologic outcomes. However, RAPPG has no benefit over LAPPG in this study.

Abstract
BACKGROUND Pylorus-preserving gastrectomy (PPG) has been performed to reduce postprandial symptoms for some early gastric cancer (EGC) cases. The aim of this study was to evaluate the possible advantages after PPG for middle-third EGC in comparison with distal gastrectomy. MATERIALS AND METHODS We searched Medline, Embase, and Science Citation Index Expanded for relevant studies. Statistical analyses were conducted to calculate the summary weighted mean differences (WMDs) and odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs) using random-effects models. RESULTS We identified 15 nonrandomized controlled trials (16 studies) with 1774 patients, which consisted of 11 studies for conventional PPG (CPPG) versus conventional distal gastrectomy (CDG) and 5 studies for laparoscopy-assisted PPG (LAPPG) versus laparoscopy-assisted distal gastrectomy (LADG). Meta-analysis of CPPG versus CDG revealed that CPPG had the advantage of prevention of early dumping syndrome (OR=0.18; 95% CI 0.12, 0.27), gastritis (OR=0.19; 95% CI 0.07, 0.53), duodenal juice reflux (OR=0.20; 95% CI 0.06, 0.66), and regaining of weight (WMD=3.53; 95% CI 2.34, 4.72). However, the incidence of gastric stasis was higher in the CPPG group than in the CDG group (OR=1.70; 95% CI 1.13, 2.57). Meta-analysis of LAPPG versus LADG revealed that LAPPG shortened the operation time (WMD=-21.12; 95% CI -31.33, -10.90) and did not increase the occurrence of postoperative complication (OR=0.72; 95% CI 0.41, 1.27). CONCLUSIONS With the benefits of prevention of early dumping syndrome, duodenal juice reflux, gastritis, and regaining of weight, PPG can be an excellent option for middle-third EGC.

Abstract
Despite declining incidence, gastric cancer remains one of the most common cancers worldwide. Early detection in population-based screening programs has increased the number of cases of early gastric cancer, representing approximately 50% of newly detected gastric cancer cases in Asian countries. Endoscopic mucosal resection and endoscopic submucosal dissection have become the preferred therapeutic techniques in Japan and Korea for the treatment of early gastric cancer patients with a very low risk of lymph node metastasis. Laparoscopic and robotic resections for early gastric cancer, including function-preserving resections, have propagated through advances in technology and surgeon experience. The aim of this paper is to discuss the recent advances in minimally invasive approaches in the treatment of early gastric cancer.

Abstract
The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures. Applications of function-preserving gastric cancer surgery may therefore also be increasing because of its low incidence of lymph node metastasis, excellent survival rates, and the possibility of less-invasive procedures such as laparoscopic gastrectomy being used in combination. Pylorus-preserving gastrectomy (PPG) with radical lymph node dissection is one such function-preserving procedure that has been applied for EGC, with the indications, limitations, and survival benefits of PPG already reported in several retrospective studies. Laparoscopy-assisted proximal gastrectomy has also been applied for EGC of the upper third of the stomach, although this procedure can be associated with the 2 major problems of reflux esophagitis and carcinoma arising in the gastric stump. In the patient with EGC in the upper third of the stomach, laparoscopy-assisted subtotal gastrectomy with a preserved very small stomach may provide a better quality of life for the patients and fewer postoperative complications. Finally, the laparoscopy endoscopy cooperative surgery procedure combines endoscopic submucosal dissection with laparoscopic gastric wall resection, which prevents excessive resection and deformation of the stomach after surgery and was recently applied for EGC cases without possibility of lymph node metastasis. Function-preserving laparoscopic gastrectomy is recommended for the treatment of EGC if the indication followed by accurate diagnosis is strictly confirmed. Preservation of remnant stomach sometimes causes severe postoperative dysfunctions such as delayed gastric retention in PPG, esophageal reflux in PG, and gastric stump carcinoma in the remnant stomach. Moreover, these techniques present technical difficulties to the surgeon. Although many retrospective studies showed the functional benefit or oncological safety of function-preserving gastrectomy, further prospective studies using large case series are necessary.

Abstract
PURPOSE This study investigated the postoperative quality of life (QOL) after laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) in comparison to laparoscopy-assisted distal gastrectomy (LADG). METHODS Twenty-one patients with early-stage gastric cancer underwent minimally invasive LADG (n = 12) or LAPPG (n = 9). Demographic and cancer-related data were obtained retrospectively from medical records. QOL was assessed using a 13-item questionnaire and the Japanese edition of the Gastrointestinal Symptom Rating Scale, which were mailed to patients twice postoperatively. Body weight and hemoglobin levels were measured at the same time. RESULTS Early upper abdominal pain was rated as significantly worse with LAPPG than with LADG at the first checkup (1.4 vs. 1.0, P = 0.02) but not at the second checkup (1.3 vs. 1.0, P = 0.07). There was a trend toward less body weight loss in the LAPPG patients in comparison to the LADG patients. The serum hemoglobin levels of LAPPG patients at the second checkup showed significantly higher than LADG patients (13.3 vs. 11.6 g/dL, P < 0.05). CONCLUSIONS LAPPG and LADG produce similar QOL in patients. Trends toward less body weight loss and improved anemia in LAPPG patients may therefore become more pronounced in future studies that have adequate number of the patients and longer follow-up periods.

Abstract
INTRODUCTION Billroth I gastroduodenostomy using a circular stapler is the most preferred reconstruction method after laparoscopy-assisted distal gastrectomy (LADG). The optimal stapler size for this procedure has not yet been proposed. METHODS Sixty-five patients who underwent LADG and stapled anastomosis with a 25-mm stapler (25-mm group) and a 29-mm stapler (29-mm group) were enrolled in this study. Clinical data and gastroscopic findings at 6 and 12 months after surgery were retrospectively reviewed. RESULTS Postoperative complications and postprandial symptoms were similar in both groups. Gastroscopically, food materials remained more frequently in the remnant stomach in the 25-mm group than in the 29-mm group at 6 months after surgery (P=.041). Gastritis and bile reflux were observed more frequently in the 29-mm group than in the 25-mm group (P=.012 and P=.015, respectively). All these differences in the gastroscopic findings between the two groups decreased at 12 months after surgery except for reflux esophagitis, which was observed more frequently in the 29-mm group (P=.002). The length of the incision was smaller in the 25-mm group than in the 29-mm group (4.39 cm versus 4.95 cm, P=.009). CONCLUSION A small-diameter stapler is a risk factor for gastric stasis in the early postoperative period, whereas a large-diameter stapler is a risk factor for gastritis and bile reflux in the early postoperative period and for esophagitis in the late postoperative period. Thus, a small-diameter circular stapler has more advantages over a large-diameter circular stapler. It also enables a reliable anastomosis through a smaller incision and easy handling of the stapler during anastomosis.

Abstract
OBJECTIVE Laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) was introduced as a function-preserving and minimally invasive operation for early gastric cancer (EGC) in Japan. This study investigated the postoperative outcomes, complications, and associated risk factors of the procedure. METHODS From January 2005 to December 2009, 307 patients with EGC diagnosed before surgery underwent LAPPG. The postoperative outcomes and complications were assessed in this study. Postoperative complications were classified according to the Clavien-Dindo classification of surgical complications, and risk factors related to complications were analyzed. RESULTS The mean operation time for LAPPG was 229.4 ± 47.5 minutes and estimated blood loss was 49.1 ± 62.0 mL. The mean total number of dissected lymph nodes was 31.6 ± 10.4, with nodal involvement observed in 25 patients (8.5%). The preoperative diagnostic accuracy of EGC was 93.2%. Complications developed in 53 patients (17.3%), and major complications, classified as grades greater than Clavien-Dindo classification IIIa, were observed in 4 patients (1.3%). The most frequent complication was gastric stasis, occurring in 19 patients (6.2%). Body mass index (BMI) and surgical experience of LAPPG were identified as significant risk factors of postoperative complications. Body mass index was related to severity of the complications. The patients' serum total protein and albumin did not change significantly after surgery. CONCLUSIONS Laparoscopy-assisted pylorus-preserving gastrectomy is a safe operation with excellent postoperative outcomes in terms of minimized major complications based on the Clavien-Dindo classification in patients with EGC in the middle third of the stomach. To prevent postoperative complications, surgeons need to ensure an extra leaning period for LAPPG, and LAPPG should be performed cautiously in patients with high BMI.

Abstract
PURPOSE To investigate the phenomenon of remnant gastric motility and emptying after local resection. METHODS Fifteen dogs were divided into three groups: a control (CONT) group, a group that underwent local resection of the greater (GREAT) curvature, and a group that underwent resection of the lesser (LESS) curvature. We conducted a strain gauge force transducer study, a [(13)C]octanoic acid breath test ((13)C-OBT), and a mosapride citrate effect test. Based on these results, we worked out the receptive relaxation (RR), motility index (MI), and postprandial period (PP) in the postprandial state, and the frequency, duration, and MI of phase III in the fasted state. The half emptying time (T (1/2)) of (13)C-OBT was also calculated. The MI was compared according to the mosapride effect test results. RESULTS Postprandial RR, antro-pyloro-duodenal coordination, and fasting contractions were maintained in all three groups. Receptive relaxation was significantly shorter in the LESS group than in the other groups. Motility index was significantly lower in both treatment groups than in the CONT group. The PP was significantly longer in the GREAT group than in the other two groups. The (13)CO(2) excretion curves did not differ significantly among the groups. The duration of phase III was remarkably less in the treatment groups than in the CONT group, and MI was significantly lower in the LESS group than in the other groups in the fasted state. The MI increased remarkably after mosapride administration in the CONT group, showing no differences in other objective groups. CONCLUSION Gastric function was maintained after gastric local resection, although its motility decreased.

Abstract
BACKGROUND The aim of this study was to investigate early and late dumping syndromes in a large number of patients after gastrectomy for gastric cancer. STUDY DESIGN Responses to questions on a visual analogue scale survey completed by 1,153 gastrectomy patients were analyzed for associations between clinical factors and occurrence of dumping syndrome. Types of gastrectomy included distal gastrectomy with Billroth I or with Roux-Y reconstruction, pylorus preserving gastrectomy, proximal gastrectomy, and total gastrectomy. RESULTS Based on the visual analogue scale rating of symptomatic discomfort, patients were categorized into 1 of 2 groups: symptom-free or symptomatic. Incidences of early or late dumping syndrome in all patients were 67.6% and 38.4%, respectively. Patients in whom early dumping syndrome developed were significantly more likely to experience late dumping syndrome than those in whom it did not develop (p < 0.001). According to multivariate analyses, factors that decreased the risk for developing early dumping syndrome were reduced weight loss (p < 0.01), old age (p < 0.01), pylorus preserving gastrectomy (p < 0.01), distal gastrectomy with Roux-Y reconstruction (p < 0.01), and distal gastrectomy with Billroth I (p = 0.019). In addition, factors that decreased the risk of developing late dumping syndrome were reduced weight loss (p = 0.03), being male (p < 0.01), pylorus preserving gastrectomy (p < 0.01), and distal gastrectomy with Roux-Y reconstruction (p < 0.01). No other clinical factors (lymph node dissection, vagal nerve preservation, and postoperative period) showed a substantial association with the occurrence of dumping syndrome in multivariate analyses. CONCLUSIONS Substantially more patients suffered from early dumping syndrome than late dumping syndrome after gastrectomy. Two clinical factors, surgical procedures and amount of body weight loss, associated significantly with the occurrence of both early and late dumping syndrome.

Abstract
Segmental resection of the stomach was first described at the end of the 19th century by Mikulicz, who devised it to preserve the pylorus when performing gastric ulcer surgery. Although this technique was abandoned because of delayed gastric emptying, in 1967 Maki et al. developed a new improved concept of segmental gastrectomy: pylorus-preserving gastrectomy (PPG). The dramatic decrease in the occurrence of gastric ulcers limited the opportunity to perform these operations; however, PPG was then used for treating early gastric cancer, the incidence of which has increased remarkably over the last two decades. From the viewpoint of surgical oncology, a rationale to justify reducing the range of lymphadenectomy is required for preserving the curability. Therefore, we devised a new technique of transectional gastrectomy using sentinel node navigation for early gastric cancer located in the middle third of the stomach. The results of a questionnaire about postoperative symptoms and endoscopic assessment indicated the superiority of transectional gastrectomy over conventional distal gastrectomy. Future confirmation of the sentinel node concept through a multi-institutional validation study conducted by the Japanese Society of Sentinel Node Navigation Surgery would lead to widespread adoption of transectional gastrectomy.

Abstract
BACKGROUND The present study investigated the efficacy of preserving the celiac branch of the vagus nerve after laparoscopy-assisted distal gastrectomy (LADG) with Roux-en-Y (R-Y) reconstruction. METHODS Between January 2004 and September 2008, a total of 159 consecutive patients who underwent LADG for gastric carcinoma were classified into groups according to preservation of the celiac branch of the vagus nerve-preservation group (P-LADG; n = 70) and the resection group (R-LADG; n = 89). The parameters analyzed included patient and tumor characteristics, operative details, postoperative outcomes, and nutritional state. The endoscopic findings of the gastric remnant and lower esophagus were evaluated at 12 months postoperatively. RESULTS In regard to postoperative complications, no significant differences were found between groups. With R-LADG, 14 patients suffered from dumping syndrome (15.7%), compared with only 2 patients with P-LADG (2.9%; P = .007). The amount of meal consumption compared with the preoperative value and the rate of weight reduction at 12 months postoperatively did not differ significantly between groups. Endoscopic findings showed significantly more residue with P-LADG (34.3%) than with R-LADG (16.9%; P = .011). CONCLUSION The celiac branch is useful in regulating gastrointestinal motility by maintaining postoperative physiologic function. Celiac branch preservation seems to represent a feasible and beneficial method for LADG.

Abstract
BACKGROUND This study was intended to examine the safety of possibly incomplete dissection of lymph node stations (LNS) 5 and 6 in pylorus-preserving gastrectomy (PPG) for gastric cancer. MATERIALS AND METHODS We reviewed the medical information from 1802 gastric cancer patients who underwent curative gastrectomy and whose lymph nodes were topographically classified according to LNS between March 2003 and December 2008. We divided the patients who underwent subtotal gastrectomy into 2 groups according to the distance between the distal resection margin (DRM) and primary tumor: those with a distance of < 6 cm (the < 6 DRM group) and those with a distance of >or= 6 cm (the >or= 6 DRM group). We analyzed the lymph node metastasis rate to LNS 5 and 6 according to T stage and the location. The number of retrieved lymph nodes according to LNS was compared between subtotal gastrectomy (STG) and PPG. RESULTS The metastasis rate to LNS 5 was very rare in >or= 6 DRM group: T1a, 0% (0 of 105); T1b, 0.9% (1 of 113); and T2a, 0% (0 of 56), although the number of retrieved LNS 5 was significantly lower in PPG than in STG. The metastasis rate to LNS 6 in the >or= 6 DRM group was significantly lower than in the < 6 DRM group, but higher than that of LNS 5: T1a, 0% (0 of 107); T1b, 1.8% (2 of 114); and T2a, 3.6% (2 of 56). The number of retrieved LNS 6 was not significantly different between STG and PPG. CONCLUSIONS PPG seems to be safe for early gastric cancer located >or= 5 cm from the pylorus in terms of LNS 5 and 6.

Abstract
BACKGROUND To clarify the significance of preserving pyloric and hepatic branches of the vagal nerve (PHV) after pylorus preserving distal gastrectomy (PPG) for early gastric cancer, the author investigated the postgastrectomy syndrome and gastric emptying function at 5 years in PPG patients with or without preserving the PHV. METHODS A total of 18 subjects (mucosal cancers) who underwent PPG with D1 lymph node dissection and preserving the PHV; they comprised group A-12 men and 6 women aged 38-68 years (mean 58.9 years). They were interviewed to inquire about gastrointestinal symptom (appetite, weight loss, gastric fullness, reflux esophagitis, early dumping syndrome) and then were compared with 24 PPG patients (submucosal cancers) with D2 lymph node dissection without preserving the PHV (group B-16 men and 8 women aged 33 to 69 years, mean 60.1 years). Esophagogastric endoscopy, abdominal ultrasonography, and gastric emptying function tests (GET) were undertaken, the latter by both radioisotope (solid diet) and acetaminophen (liquid diet) methods. RESULTS There were no differences in the postoperative gastrointestinal symptoms, endoscopic reflux esophagitis, or endoscopic mucosal edema and redness (gastropathy) between groups A and B. However, more cholecystolithiasis (gallbladder stones) was found in group A than in group B, with the difference being significant (P < 0.0391). The GET for solid diet and liquid diet were the almost same among groups A and B. CONCLUSIONS There were no significant differences in the postoperative QOL and GET between PPG patients with preserving PHV and those without preserving PHV. Cholecystolithiasis was only found in patients without preserving PHV.

Abstract
BACKGROUND AND AIM The aim of the present study was to evaluate gastric motor function by magnetic resonance imaging (MRI) and investigate whether this examination is a useful tool for therapeutic efficacy or postoperative gastric motor function. METHODS Twenty-five healthy volunteers and 10 gastric cancer patients with pylorus-preserving gastrectomy (PPG) underwent cine-MRI. Gastric volume was determined by 3D-volumetry. Gastric motility was quantified by calculating the gastric motility index (GMI). RESULTS The image acquisition and analysis were successfully carried out for all subjects. In healthy volunteers, mean frequency, amplitude, velocity of gastric peristaltic waves and GMI 30 min after the intake of jelly were 3/min, 8.8 mm, 2.2 mm/s and 19.6 mm2/s, respectively. Mean amplitude (8.8 vs 10.4 mm, P = 0.027), velocity (2.2 vs 2.6 mm/s, P < 0.001) of peristaltic waves, and GMI (19.6 vs 26.7 mm2/s, P < 0.001) significantly increased at 30 min after giving mosapride citrate (MS). Mean gastric volume after MS administration was significantly decreased; 0 min (317.3 vs 272.9 mL, P = 0.021), 45 min (263.4 vs 206.4 mL, P = 0.004) and 60 min (228.7 vs 165 mL, P = 0.001). PPG patients with postprandial symptoms were observed having antiperistalsis-like contraction waves and reflux of gastric contents from the pyloric region into the upper part of the stomach. Mean gastric volume in PPG patients with postprandial symptoms at 30 min after intake of jelly tended to be greater than in those without such symptoms. CONCLUSIONS The present study demonstrates that cine-MRI is a sensitive and non-invasive imaging technique for simultaneously measuring gastric motility and emptying.

Abstract
BACKGROUND Pylorus-preserving gastrectomy (PPG) was originally a treatment option in gastric ulcer surgery and is now being performed as a limited surgery in some early gastric cancer cases. This study was designed to evaluate the postoperative functional characteristics of PPG versus conventional distal gastrectomy with Billroth I anastomosis (BI). METHODS Patients who underwent PPG (study group) between November 1999 and April 2003 were enrolled and BI patients (control group) were matched for number, gender, age, weight, height, stage, and follow-up period. We evaluated postprandial symptoms and nutritional status. Gastric emptying studies with a 99mTc gamma camera, follow-up endoscopies with random biopsies of remnant gastric mucosa to evaluate bile reflux gastritis, and ultrasonography to detect gallbladder stones were performed. Recurrence and survival also were investigated. RESULTS Twenty-two PPG patients (study group) and 17 BI patients (control group) were enrolled. Overall modified Visick scores of postprandial symptoms were lower in PPG patients than in BI patients (0.9 +/- 0.7 vs. 2.3 +/- 1.4; p = 0.018). Gastric emptying was delayed in PPG patients versus BI patients for solids (p < 0.05). Moderate gastritis, bile reflux, and gallbladder stone were observed only in BI patients. Remnant stomach pathologic findings corresponding to bile reflux gastritis in the two groups were similar, except for Helicobacter pylori colonization. No recurrence occurred in either group (mean follow-up period = 41 +/- 9.5 months). CONCLUSIONS PPG patients had fewer subjective postprandial symptoms than BI patients. The present study also suggests that PPG has advantages over BI in terms of the avoidance of bile reflux and gallbladder stones.

Abstract
Abstract
Background
Pylorus-preserving gastrectomy has been introduced as a function-preserving operation for early gastric cancer in Japan. The aim of this study was to investigate the safety and radicality of the procedure.
Methods
Between 1995 and 2004, 611 patients with apparent early gastric cancer in the middle third of the stomach had pylorus-preserving gastrectomy. The short-term surgical and long-term oncological outcomes of these operations were assessed.
Results
The accuracy of preoperative diagnosis of early gastric cancer was 94·3 per cent. Nodal involvement was seen in 62 patients (10·1 per cent). There were no postoperative deaths. Complications developed in 102 patients (16·7 per cent). Major complications, such as leakage and abscess, were observed in 19 (3·1 per cent). The most common complication was gastric stasis, occurring in 49 (8·0 per cent). The overall 5-year survival rate in patients with early gastric cancer was 96·3 per cent.
Conclusion
Pylorus-preserving gastrectomy is a safe operation with an excellent prognosis in patients with early gastric cancer. It is recommended as the standard procedure for early gastric cancer in the middle third of the stomach.

Abstract
BACKGROUND Pylorus-preserving gastrectomy (PPG) prevents postprandial symptoms; however, delayed gastric retention due to aberrant pylorus function can occur during the early postoperative period. This study aimed to establish a stasis-less PPG procedure with preservation of the vagal nerve and blood flow to the pyloric cuff, and to apply the technique for laparoscopy-assisted PPG. METHODS Ninety patients with T1 gastric cancer located in the middle third of the stomach were enrolled in this study for surgery from January 2003 to March 2006, undergoing either laparoscopy-assisted PPG (LAPPG; 39 patients) or conventional PPG (CPPG; 51 patients). Operative and early postoperative outcomes were compared between the two groups. RESULTS Relatively low rates of gastric stasis were observed in both the LAPPG (8%) and CPPG (6%) groups. Estimated blood loss in LAPPG (65.4 +/- 12.3 ml) patients was significantly lower than in the CPPG group (160.7 +/- 19.6 ml) (p < 0.001), and the total number of dissected lymph nodes was significantly greater in the LAPPG group (36.2 +/- 1.8) than in the CPPG group (29.0 +/- 1.3) (p = 0.001). CONCLUSIONS A PPG procedure with less postoperative stasis and adequate lymph node retrieval was established and applied successfully in laparoscopy-assisted surgery.

Symptom evaluation of long-term postoperative outcomes after pylorus-preserving gastrectomy for early gastric cancer. Gastric Cancer 2008; 10:167-72. [PMID: 17922094 DOI: 10.1007/s10120-007-0434-7] [Citation(s) in RCA: 95] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2007] [Accepted: 07/30/2007] [Indexed: 02/07/2023]
Abstract
BACKGROUND Since the early 1990s, pylorus-preserving gastrectomy (PPG) has been used in the treatment of patients with early gastric cancer in order to reduce postprandial symptoms. To date, there have been few reports of long-term symptom evaluation following this procedure. The aim of this study was to evaluate long-term postoperative outcomes after PPG. METHODS Three hundred and ninety-seven patients with early gastric cancer were enrolled in this study: 194 patients who underwent PPG and 203 who underwent distal gastrectomy with Billroth-I reconstruction (DGBI). We compared the symptoms for the two groups in a questionnaire on postoperative functional outcomes, endoscopy findings and the appearance of gallstones after surgery. RESULTS The incidence of symptoms suggesting early dumping syndrome was significantly lower in the PPG group compared with the DGBI group (P < 0.05). The incidences of disturbed bowel habit and frequent flatus were significantly lower in the PPG than in the DGBI group. The average relative body weight (actual BW/ BW immediately before the surgery) was significantly better in the PPG than in the DGBI group (P < 0.001). CONCLUSION The long-term results show that PPG has clear advantages over DGBI in terms of postoperative symptoms and functional outcomes. These results imply that PPG should be the recommended procedure for early gastric cancers located in the middle third of the stomach.

Billroth 1 versus Roux-en-Y reconstructions: a quality-of-life survey at 5 years. Int J Clin Oncol 2007; 12:433-9.

Abstract
BACKGROUND In the majority of gastric surgical units across Japan, Billroth 1 is the preferred method of anastomosis following subtotal distal gastrectomy for gastric cancer. However, across Europe and North America, reconstruction using a Roux-en-Y anastomosis is more common. There is a lack of comparative studies of the two methods focusing on long-term outcome. This study evaluated patient outcome, in terms of adverse gastrointestinal complaints and quality of life, at 5 years following surgery. METHODS A total of 652 patients had a subtotal distal gastrectomy for early gastric cancer between January 1993 and December 1999. We studied 229 patients with reconstruction by the Billroth 1 procedure and 214 patients with the Roux-en-Y procedure. All patients had an abdominal ultrasound and endoscopy as part of their follow-up. Quality of life was assessed by questionnaire. RESULTS We had an 87% response rate from the questionnaire assessment. The results demonstrated that patients were less likely to experience symptoms of either early or late dumping after Roux-en-Y anastomosis than after Billroth 1. In addition, there were significantly fewer patients with gastritis on endoscopy in the Roux-en-Y group. There was no significant difference in the average relative body weight between the groups. However, patients were more likely to develop gallstones after a Roux-en-Y than after a Billroth 1 reconstruction. CONCLUSION The results from this study show that, at 5 years, both symptomatically and functionally, Roux-en-Y reconstruction was superior to the Billroth I method after subtotal distal gastrectomy for gastric cancer. However, the overall outcome in both groups was good, with patient satisfaction scores of around 75% in each group.

Abstract
BACKGROUND This study evaluated the preserved function of the remnant stomach by gastric emptying scintigraphy in patients who underwent pylorus-preserving gastrectomy (PPG), and it investigated whether this examination method is a useful tool for evaluation. MATERIALS AND METHODS The residual stomach function was evaluated by gastric emptying scintigraphy in 45 patients with early gastric cancer who had undergone PPG. Function was classified as rapid, intermediate, and delayed emptying types according to gastric emptying curves. Then, the relationships were examined between the gastric emptying types and postprandial symptoms, food intake status, body weight changes, and endoscopic findings. RESULTS Seventy-three percent of the PPG patients were classified as belonging to the intermediate emptying type, and the remainder to the delayed emptying type. The frequencies of complaints such as epigastric fullness, nausea, and vomiting were high in the delayed emptying-type patients. The intermediate emptying-type patients consumed larger amounts of food and gained more weight than the delayed emptying-type patients. It was difficult to estimate gastric emptying function from endoscopic findings. CONCLUSIONS Gastric function was evaluated by gastric emptying scintigraphy in PPG patients. This method might be useful not only for evaluating the motor function of the remnant stomach, but also for predicting postoperative status.

Abstract
BACKGROUND We investigated the relationship between interdigestive migrating motor complex, phase III (IMMC-pIII) and postoperative quality of life (QOL) in pylorus-preserving gastrectomy (PPG) patients. MATERIALS AND METHODS A total of 40 patients (26 men and 14 women; average age 59.4 years) 5 to 7.5 years after PPG for early gastric cancer (Billroth I) (average 6 years and 3 months) were divided into two groups according to the occurrence of IMMC-pIII from the duodenum, and their postoperative quality of life (QOL) was compared. RESULTS As for appetite, "No change compared with before operation" was significantly more frequent in the IMMC-pIII positive group compared with the negative group (P=0.0002). Food consumption per meal compared with normal; "80% or more" was significantly more frequent in the IMMC-pIII positive group than the negative group (P=0.0002). Body weight loss during 5 years after surgery; "6 kg or more" was significantly more frequent in the IMMC-pIII negative group than the positive group (P=0.0002). Early dumping symptoms did not occur in any patients of either group. Reflux esophagitis and nausea; no patients in the IMMC-pIII positive group experienced these symptoms, which was significantly different from the negative group (P=0.0018). Abdominal pain occurred but was significantly less frequent in the IMMC-pIII positive group than in the negative group (P=0.0023). Epigastric fullness occurred but was less frequent in the IMMC-pIII positive group compared with the negative group (P<0.0001). Gastric stasis of the remnant stomach was significantly more frequent in the IMMC-pIII negative group than in the positive group (P<0.0001). Gholelithiasis was significantly more frequent in the IMMC-pIII negative group than in the positive group (P=0.0119). CONCLUSIONS These results showed more satisfactory QOL in the IMMC-PIII positive group than in the negative group.

Abstract
BACKGROUND Total and subtotal gastrectomies are methods of choice in surgical treatment of gastric cancer. These ablative operations eliminate the gastric reservoir and severely alter digestive physiology. METHODS We have created a unique method of reconstruction of "the jejunal pouch" following gastrectomy using the first loop of the jejunum together with the formation of antireflux anastomosis. RESULTS An analysis of the results of the application of a new way of reconstruction of the digestive path was carried out. Seventy-five patients with gastric cancer received the new type of reconstruction. Among them, there were 52 men and 23 women aged 36-72 years. In the new interposition method group, in the first year after the surgical operation, the patients returned to 89.8% of their original body weight and in the second year to 89.7%; and in the Roux-en-Y group the patients returned to 64.4% and 59.2% of their body weight respectively. Further body weight fluctuations in patients after the new operative technique were determined by diet and aging and were not connected with digestive disorders. In the group receiving the new operative technique, the dumping syndrome was recorded in 4 (5.3%) patients and in the Roux-en-Y operation this syndrome occurred in 22 (27.5%) patients more than 1 year following the operations. There were no cases of reflux disease in the group undergoing the new operative technique. The average evacuation time of the "jejunal pouch" was 84+/-9.8 min after the new operation and 57.5+/-10.1 minutes after the Roux-en-Y operation. CONCLUSIONS The comparative analysis of the results of the new operation (75 patients) with 80 patients (who were operated on using the traditional method) after the Roux-en-Y operation showed the significant advantages of the new method due to a diminished occurrence of troublesome gastrointestinal symptoms. We consider that the reconstruction of the gastrointestinal tract after total gastrectomy should give the maximal comfort for the rest of the patient's life.

Abstract
Previously proposed criteria of less invasive surgery for early gastric cancer (EGC) were based mainly on the pathological analyses of the resected specimens; however, preoperative and intraoperative information are also obviously essential for decision making on stage-dependent patient management. Furthermore, most indications and treatment options have not been systematically integrated or evaluated by treatment outcomes. We investigate in this report the rationality of less invasive surgery employed for EGC. Distribution analyses of positive nodes were investigated among 684 patients with primary solitary EGC (379 mucosal and 305 submucosal) who underwent curative resection between 1976 and 2000. Clinicopathological factors highlighted and analyzed included clinical (preoperative and intraoperative) and pathological (postoperative) cancer depth and nodal involvement, gross form, histological type, and maximum cancer diameter, as well as postoperative morbidity and mortality. The scope of lymphadenectomy can be reduced to a modified D1 for clinically mucosal, node-negative, nonpalpable gastric cancer, or for clinically submucosal, node-negative gastric cancer < or = 1.5 cm for intestinal type, or < or = 1.0 cm for diffuse type. Otherwise, a modified D2 lymphadenectomy is sufficient. Local resection can be recommended for clinically mucosal, node-negative gastric cancer without apparent ulceration < or = 4 cm if adjacent lymph nodes are proved cancer negative by a frozen section examination. If the gastric cancer has spread beyond the above criteria, a pylorus-preserving gastrectomy (PPG) can be recommended for tumors located in the middle or lower third of the stomach, provided the distal margin of the cancer is at least 4.5 cm from the pyloric ring. The PPG can be accompanied by a modified D1 or a modified D2 lymphadenectomy according to the respective dissection criteria. Results of these less invasive strategies showed reduced morbidity and mortality, as well as no recurrence or cancer-related deaths. These results suggest that each of our criteria for less invasive surgery for EGC is realistic, well stratified, and satisfactory.

Abstract
BACKGROUND AND AIMS Recent results from long-term follow-up of a large number of patients who have undergone gastric resection for early gastric cancer (EGC) have not yet been fully evaluated. PATIENTS AND METHODS A total of 848 patients who had undergone gastric resection for EGC (262 female, 586 male; mean age 58.0 years; range 20-86 years) were studied with respect to surgical technique, long-term survival and prognostic factors on the basis of current TNM classification. RESULTS Death related to recurrence occurred in only eight patients (0.9%). Hematogenous metastasis to the liver or bone represented the most common pattern of recurrence, developing in six of the eight recurrences (75%). The 5-year and 10-year cancer-related survival rates were 98.6% and 94.8%, respectively. The 5-year and 10-year overall survival rates were 95.2% and 85.0%, respectively. Lymph node metastasis represented an independent prognostic factor when analyzed on the basis of cancer-related survival. CONCLUSION The present findings indicate that long-term survival of patients who undergo gastric resection for EGC is extremely good and that lymph node metastasis represents an independent prognostic factor when analyzed according to cancer-related survival. Future developments for the treatment of EGC are expected to improve quality of life for patients after gastric resection.
