Abstract Objective To explore the efficacy of esophagogastrostomy plus gastrojejunostomy reconstruction after proximal gastrectomy. Methods The clinical data of 75 cases of gastrectomy for proximal gastric neoplasm between January 2003 and January 2012 at the Affiliated Tumor Hospital of Guangzhou Medical University were analyzed retrospectively. There were 26 cases of proximal gastrectomy followed by esophagogastrostomy reconstruction (EG)??27 cases of total gastrectomy and Roux-en-Y reconstruction (RY) and 22 cases of proximal gastrectomy followed by esophagogastrostomy plus gastrojejunostomy reconstruction (EGJ) respectively. The clinicopathological features, operation time, intraoperative bleeding volume??postoperative complications and nutritional status were compared among three different reconstruction types. Results The operation time??intraoperative bleeding volume and nutritional status in postoperative 12 months were similar among the three groups (P??0.05). The incidence of reflux esophagitis in the EG group (57.7%) was higher than that in the RY (11.1%) and EGJ groups (9.0%) significantly (P??0.01). No case in EGJ group suffered from severe reflux esophagitis. Conclusion EGJ procedure can significantly relieve the syndrome of reflux esophagitis and may be a simple and effective reconstruction method after proximal gastrectomy.     

Comparison of Billroth I and Roux-en-Y Reconstruction after Distal Gastrectomy for Gastric Cancer: One-year Postoperative Effects Assessed by a Multi-institutional RCT

Purpose

This randomized, controlled trial evaluated the clinical efficacy of Billroth I (BI) and Roux-en-Y (RY) reconstruction at 1 year after distal gastrectomy for gastric cancer.

Methods

The primary end point was the amount of body weight lost at 1 postoperative year, and secondary end points included other items related to nutritional status such as serum albumin and lymphocyte count, as well as endoscopic examination findings of the remnant stomach and esophagus. Of the 332 patients enrolled, 163 were assigned to the BI group and 169 were randomized to the RY group.

Results

The loss in body weight 1 year after surgery did not differ significantly between the BI and RY groups (9.1 % and 9.7 %, respectively, p = 0.39). There were no significant differences in other aspects of nutritional status between the 2 groups. Endoscopic examination 1 year after gastrectomy showed reflux esophagitis in 26 patients (17 %) in the BI group versus 10 patients (6 %) in the RY group (p = 0.0037), while remnant gastritis was observed in 71 patients (46 %) in the BI group versus 44 patients (28 %) in the RY group (p = 0.0013); differences were significant for both conditions. Multivariable analysis showed that the only reconstruction was the independently associated factor with the incidence of reflux esophagitis.

Conclusions

RY reconstruction was not superior to BI in terms of body weight change or other aspects of nutritional status at 1 year after surgery, although RY more effectively prevented reflux esophagitis and remnant gastritis after distal gastrectomy.     

Evaluation of symptoms related to reflux esophagitis in patients with esophagogastrostomy after proximal gastrectomy

Purpose

We investigated postoperative symptoms related to reflux esophagitis in patients who underwent esophagogastrostomy reconstruction after proximal gastrectomy (PG) by conducting a questionnaire survey.

Method

Quality of life was assessed using two different questionnaires, the gastrointestinal symptom rating scale (GSRS) for postoperative abdominal symptoms and F-scale for reflux esophagitis. The survey was conducted among 39 patients who underwent esophagogastrostomy after proximal gastrectomy for gastric cancer in the upper third of the stomach, and findings were compared with those in patients who underwent total gastrectomy (TG).

Results

The questionnaire was returned by 32 of 39 patients (82%) in the PG group and 40 of 45 patients (89%) in the TG group. On GSRS, the score for indigestion syndrome tended to be higher in the TG group than in the PG group (p?<?0.10), and the score for constipation was significantly higher in the PG group than in the TG group (p?<?0.05). The score for reflux syndrome, however, was almost the same in both groups. Similarly, there was no significant difference in the frequency of GERD symptoms between the PG and TG groups on F-scale questionnaire (47% vs. 63%, p?=?0.18).

Conclusions

Esophagogastrostomy after PG in an end-to-side manner with creation of acute angle at the anastomosis is not associated with an increased risk of reflux esophagitis compared with TG.     

Esophagogastric tube reconstruction with stapled pseudo-fornix in laparoscopic proximal gastrectomy: a novel technique proposed for Siewert type II tumors

Purpose

The incidence of adenocarcinoma of the esophagogastric junction is increasing, but laparoscopic proximal gastrectomy is not widely accepted due to the absence of a standardized technique of reconstruction. This report describes a novel technique of esophagogastric tube reconstruction in laparoscopic proximal gastrectomy for Siewert type II tumors.

Methods

Laparoscopic proximal gastrectomy, sometimes with transhiatal distal esophagectomy, was performed. After a perigastric, suprapancreatic, and lower thoracic paraesophageal lymphadenectomy, a gastric tube of 35-mm width was prepared. An esophagogastric tube anastomosis with pseudo-fornix was made with a no-knife linear stapler to prevent postoperative reflux esophagitis.

Results

Fifteen patients with Siewert type II tumors underwent this operation. They included six patients with early-stage cancer, six at high risk for transhiatal total gastrectomy due to several comorbidities, and three who needed palliative tumor resection. The mean operation time was 315 min. One postoperative anastomotic leak was treated conservatively, and three anastomotic stenoses were resolved with endoscopic balloon dilatation. Postoperative 1-year follow-up endoscopy revealed four cases of reflux esophagitis that were well controlled by medication.

Conclusions

This new technique of reconstruction was feasible. With the advantage of a gastric tube, a tension-free anastomosis was possible even for bulky tumors that needed lower esophagectomy. Although long-term follow-up and a larger number of patients are required to evaluate long-term functional outcomes and oncological adequacy, our procedure has the potential of becoming a treatment of choice for early-stage Siewert type II tumors and/or for some selected high-risk patients who need tumor resection.     

Long-term Outcome after Proximal Gastrectomy with Jejunal Interposition for Gastric Cancer Compared with Total Gastrectomy

Background

Proximal gastrectomy (PG) has been widely accepted as treatment for early gastric cancer located in the upper third of the stomach. Reconstruction by jejunal interposition has been known to reduce reflux esophagitis for PG patients. The aim of this study was to compare the long-term outcomes of patients who underwent PG with jejunal interposition with those treated by total gastrectomy (TG).

Methods

Data on 102 cases of PG with jejunal interposition and 49 cases of TG with Roux-Y reconstruction for gastric cancer were analyzed retrospectively in terms of overall survival, weight maintenance, anemia and nutritional status, and endoscopic findings.

Results

Median follow-up time was 59 months in the both groups. There was no significant difference in the overall 5-year survival rate between the PG group (94 %) and the TG group (84 %). The PG group showed significantly better body weight maintenance at the first year. The laboratory blood tests showed that the PG group had a significantly better red blood cell count and hemoglobin and hematocrit levels at the second and third year. However, postoperative endoscopic surveillance detected reflux esophagitis (3 %), peptic ulcer (9 %), and metachronous gastric cancer (5 %) in the PG group.

Conclusions

Proximal gastrectomy maintains comparable oncological radicality to TG and is preferred over TG in terms of preventing postoperative anemia. However, periodic endoscopic follow-up is necessary to monitor the upper gastrointestinal tract.     

Evaluation of the delta-shaped anastomosis in laparoscopic distal gastrectomy: midterm results of a comparison with Roux-en-Y anastomosis

Background

Various methods of reconstruction after laparoscopic distal gastrectomy (LDG) have been developed and published, whereas only a limited number of reports are available on the utility of the delta-shaped anastomosis (Delta). This study compared Delta and Roux-en-Y anastomoses (RY), with the aim to clarify the utility of Delta.

Methods

Stage 1 gastric cancer patients who had undergone LDG with Delta (group D, n = 68) and those who had undergone LDG with RY (group RY, n = 60) were compared in terms of operative outcomes, postoperative clinical symptoms, gastrointestinal fiberscopic findings, and changes in body weight.

Results

Both the operative and anastomotic times were significantly shorter in group D (230 and 13 min, respectively) than in group RY (258 and 38 min, respectively) (p < 0.001). Among the complications observed at the anastomotic site, obstruction was seen in one group D patient and two group RY patients but was relieved with conservative management. Postoperative clinical symptoms were reported for 26.4 % of the group D patients but had decreased to 5.9 % 1 year later. Group RY yielded similar results. Upper gastrointestinal fiberscopy performed 1 year postoperatively showed no intergroup differences in the incidence of gastritis or residual retention and a significantly more frequent occurrence of bile reflux in group D. Postoperative weight changes did not differ between the two groups.

Conclusions

Delta reconstruction after LDG is a safe and effective procedure that is totally laparoscopic, less time consuming, and associated with a favorable postoperative course and a better quality of life.     

Outcome of overlap anastomosis using a linear stapler after laparoscopic total and proximal gastrectomy

Background

Recently, novel intracorporeal esophagojejunostomy using a linear stapler after laparoscopic total gastrectomy (LTG) was reported and termed as the overlap method. In this study, we evaluated the feasibility and safety of the overlap method for esophagojejunostomy or esophagogastrostomy after LTG or laparoscopic proximal gastrectomy (LPG), respectively.

Methods

Twenty-five patients underwent anastomosis using a linear stapler during esophagojejunostomy and esophagogastrostomy after LTG and LPG, respectively. Clinicopathological data and surgical outcomes were evaluated.

Results

The average surgical duration for LTG was 236.8?min compared with 224.1?min for LPG. Postoperative complications were observed in four patients (16.0%); these included a wound infection, an intestinal obstruction, an afferent loop syndrome, and a reflux symptom. The average postoperative hospital stay of the patients was 12.5?days. There was no case of conversion to open surgery, anastomotic leakage or stenosis, or mortality.

Conclusions

The overlap method for esophagojejunostomy or esophagogastrostomy after LTG or LPG is safe and feasible and does not require an additional minilaparotomy, which may result in less pain and favorable cosmetic outcomes.     

Surgical techniques to prevent reflux esophagitis in proximal gastrectomy reconstructed by esophagogastrostomy with preservation of the lower esophageal sphincter,pyloric and celiac branches of the vagal nerve,and reconstruction of the new His angle for early proximal gastric cancer

Purpose

This article describes the surgical techniques to prevent reflux esophagitis (RE) after proximal gastrectomy reconstructed by esophagogastrostomy (PGE) preservation of the lower esophageal sphincter (LES) and both pyloric and celiac branches of the vagal nerve (PCVN), and reconstruction of the new His angle (HA) for early proximal gastric cancer (PGC).

Methods

Twenty patients after PGE were divided into 2 groups (group A: 10 patients without preserved LES and PCVN for advanced PGC; group B: 10 patients with preserved LES and PCNV and the addition of a new HA for early PGC). A postoperative interview on gastroesophageal reflux disease (GERD) and satisfaction with this procedure and the collection of endoscopic findings for RE and stasis of the remnant stomach (SRS) were conducted 1 year after PGE in groups A and B.

Results

The rates of proton pump inhibitor administration and the symptoms of GERD, RE and SRS in group A were significantly higher than those in group B (p = 0.0433, p = 0.0190, p = 0.0253, p = 0.0190, respectively). Seven out of 10 patients in group A voiced dissatisfaction. Patients in group B were significantly more satisfied with this procedure than those in group A (p = 0.0010).

Conclusion

This method is useful for preventing postoperative GERD including RE in early PGC patients.

     

Comparison Between Billroth-II with Braun and Roux-en-Y Reconstruction After Laparoscopic Distal Gastrectomy

Purpose

This study aims to compare the effectiveness of Billroth-II with Braun and Roux-en-Y reconstruction after laparoscopic distal gastrectomy.

Methods

From April 2010 to August 2012, 66 patients underwent laparoscopic distal gastrectomy (Billroth-II with Braun reconstruction, 26; Roux-en-Y, 40). The patients’ data were collected prospectively and reviewed retrospectively.

Results

The mean operation and reconstruction times were statistically shorter for Billroth-II with Braun reconstruction than Roux-en-Y (198.1?±?33.0 vs. 242.3?±?58.1 min, p?=?0.001). One case of postoperative stricture was observed in each group. One case each of intra-abdominal abscess and delayed gastric emptying occurred in the Billroth-II with Braun group. At 1 year postoperatively, gastric residue and reflux esophagitis were not significantly different between the groups. Gastritis and bile reflux were more frequently observed in the Billroth-II with Braun group (p?=?0.004 and p?<?0.001, respectively). At 2 years postoperatively, gastric residue was not significantly different, but gastritis, bile reflux, and esophagitis were more frequent in the Billroth-II with Braun group (p?=?0.029, p?<?0.001, and p?=?0.036, respectively).

Conclusion

The postoperative effectiveness of Roux-en-Y reconstruction may be superior to Billroth-II with Braun reconstruction after laparoscopic distal gastrectomy.

     

HER2 Expression in Carcinomas of the True Cardia (Siewert Type II Esophagogastric Junction Carcinoma)

Objectives

To evaluate the HER2 status in patients with Siewert type II esophagogastric junction carcinoma.

Background

Trastuzumab is now approved for use in the treatment of human epidermal growth factor receptor 2 (HER2)-positive unresectable metastatic gastric or esophagogastric junction (EGJ) carcinoma. Several studies have evaluated HER2 status in EGJ carcinoma, but none has addressed the implication of HER2 positivity in patients with Siewert type II EGJ carcinoma.

Methods

We retrospectively evaluated the frequency of HER2 positivity in a large single-center cohort of 208 patients with Siewert type II tumors. The relations between HER2 expression and the outcomes and other clinicopathologic features were examined.

Results

Overall, 18.2 % (38/208) of patients in our cohort had HER2-positive tumors. HER2 positivity was associated only with differentiated carcinomas. The 5-year overall survival (OS) rate was 58.7 %. The 5-year OS rates in the patient groups with HER2-negative and HER2-positive tumors were 61.2 and 48.5 %, respectively. There was no significant difference between the groups. Recurrence in the liver was observed in 23.7 % patients of the HER2-positive group and 7.6 % patients of the HER2-negative group. Multivariate analysis to identify the risk factors for liver recurrence revealed only HER2 positivity (p = 0.0155) as an independent predictive factor.

Conclusions

HER2 positivity is a powerful predictor of liver recurrence in patients with Siewert type II EGJ carcinoma. Use of trastuzumab in combination with chemotherapy in an adjuvant setting can be a potentially useful therapeutic strategy to prevent hepatic recurrence in patients with resectable EGJ adenocarcinoma showing HER2 overexpression.     

A novel laparoscopic procedure for treating proximal early gastric cancer: laparoscopy-assisted pylorus-preserving nearly total gastrectomy

Purpose

Pylorus-preserving nearly total gastrectomy (PPNTG) is a function-preserving gastrectomy for treating proximal early gastric cancer that prevents rapid gastric emptying and reflux. In this report, we present a surgical technique for performing laparoscopy-assisted PPNTG (LAPPNTG).

Methods

The resection of the stomach was similar to that during conventional total gastrectomy, with the key difference being that the pyloric cuff was preserved to a length of 3–4 cm. Compared with standard total gastrectomy, the lymph node dissection along the right gastric vessels and the infrapyloric vessels were omitted. Reconstruction was performed with a jejunal interposition that was 30 cm in length, with preservation of the marginal vessels in a retrocolic fashion.

Results

Thirteen patients with cT1 cN0 proximal gastric cancer underwent LAPPNTG at our institution. The median length of the operation and estimated blood loss were 329 min and 138 ml, respectively. All resected specimens had tumor-free margins, and the median number of removed lymph nodes was 40. There were no serious postoperative complications and no patients underwent conversion to laparotomy.

Conclusions

Performing LAPPNTG with a jejunal interposition is feasible and might be an appropriate treatment for proximal early gastric cancer.     

What is the best reconstruction method after distal gastrectomy for gastric cancer?

Background

We performed this prospective randomized study to evaluate what is the best reconstruction method after distal gastrectomy for gastric cancer.

Methods

One hundred fifty-nine patients who underwent laparoscopy-assisted or open gastrectomy for gastric cancer were analyzed from March 2006 to August 2007. Billroth I (B-I) anastomosis, Billroth II (B-II) with Braun anastomosis, and Roux-en-Y (R-Y) anastomosis were applied randomly. Additionally, the patients were divided into two groups based on treatment type: laparoscopic and open operation. Endoscopy and hepatobiliary scans were performed to investigate gastric stasis and enterogastric reflux. The Gastrointestinal Quality of Life Index (GIQLI) was used to evaluate postoperative quality of life, and the hematologic test was used to assess nutritional aspect.

Results

Endoscopy revealed that reflux after the R-Y anastomosis procedure was significantly less frequent than after the other anastomosis types at 12?months. Comparison of the GIQLI and the nutritional parameters between the reconstruction types revealed that there were no differences, but a significantly higher GIQLI score was observed in the laparoscopic group immediately following the procedure (P?=?0.042).

Conclusions

R-Y anastomosis is superior to B-I and B-II with Braun anastomosis in terms of frequency of bile reflux, despite the fact that there is no difference in the postoperative quality-of-life index and nutritional status between reconstructive procedures. The laparoscopic approach is the better option than open surgery in terms of QOL in the immediate postoperative period.     

Postoperative long-term evaluation of interposition reconstruction compared with Roux-en-Y after total gastrectomy in gastric cancer: prospective randomized controlled trial

Background

The postoperative clinical superiority of the interposition of jejunum reconstruction (INT) to Roux-en-Y reconstruction (RY) after total gastrectomy has not been clarified. Postoperative quality of life (QOL) was evaluated between the 2 methods by a multi-institutional prospective randomized trial.

Methods

A total of 103 patients with gastric cancer were prospectively randomly divided into groups for RY (n = 51) or INT reconstruction (n = 52) after total gastrectomy. They were stratified by sex, age, institute, histology, and degree of lymph node dissection. Postoperatively, body mass index (BMI) and nutritional conditions were measured serially, and QOL and postoperative squalor scores were evaluated at 3, 12, and 60 months and compared between the 2 groups.

Results

After removing patients who did not complete the follow-up survey or censured cases, 24 patients in the RY group and 18 patients in the INT group were clinically available and their postoperative status was assessed. QOL scores were increased and complication scores were improved in the postoperative periods (P < .01). Postoperative BMI significantly deteriorated compared with preoperative BMI in each group. The postoperative QOL and complication scores at 60 months after surgery were significantly better than those at 3 months after surgery in each group (P < .01). However, there was no significant difference of QOL scores and postoperative complication scores between the 2 reconstruction groups. The nutritional condition in the INT group was nearly the same as that in the RY group.

Conclusions

Although our patient sample was small and patients who did not complete the follow-up survey were present, we could not identify any clinical difference between INT and RY after total gastrectomy 60 months after surgery. The safer and simpler RY method may be a more suitable reconstruction method than INT after total gastrectomy.

Prevalence of Barrett’s Esophagus in Bariatric Patients Undergoing Sleeve Gastrectomy

Background

The appearance and incidence of gastroesophageal reflux after sleeve gastrectomy is not yet resolved, and there is an important controversy in the literature. No publications regarding the appearance of Barrett’s esophagus after sleeve gastrectomy are present in the current literature.

Purpose

The purpose of this paper was to report the incidence of Barrett’s esophagus in patients submitted to sleeve.

Material and Methods

Two hundred thirty-one patients are included in this study who were submitted to sleeve gastrectomy for morbid obesity. None had Barrett’s esophagus. Postoperative upper endoscopy control was routinely performed 1 month after surgery and 1 year after the operation, all completed the follow-up in the first year, 188 in the second year, 123 in the third year, 108 in the fifth year, and 66 patients over 5 years after surgery.

Results

Among 231 patients operated on and followed clinically, reflux symptoms were detected in 57 (23.2 %). Erosive esophagitis was found in 38 patients (15.5 %), and histological examination confirmed Barrett’s esophagus in 3/231 cases (1.2 %) with presence of intestinal metaplasia.

Conclusion

Bariatric surgeons should be aware of the association of gastroesophageal reflux (GER) disease and obesity. Appropriate bariatric surgery should be indicated in order to prevent the occurrence of esophagitis and Barrett’s esophagus.

     

Laparoscopic Roux limb Placement over a Fistula Defect Without Mucosa-to-Mucosa Anastomosis: a Modified Technique for Surgical Management of Chronic Proximal Fistulas After Laparoscopic Sleeve Gastrectomy

Background

Laparoscopic sleeve gastrectomy (LSG) is an increasingly popular bariatric procedure. A chronic fistula at the esophago-gastric junction (EGJ) is a rare but life-threatening complication of this procedure whose causes are still unclear and management is still controversial.

Methods

A 41-year-old woman with a body mass index (BMI) of 38 developed an EGJ leak 6 days post-LSG. Despite initial control with conservative measures, the leak persisted and resulted in a left pleural abscess and a broncho-pleural fistula requiring thoracotomy with resection of the abscessed lung parenchyma. Endoscopic and drainage procedures failed to prevent subdiaphragmatic recurring collection due to the persistent fistula. Nineteen months after LSG, a Roux limb was placed on the EGJ and sutured side to side around the fistula defect, without mucosa-to-mucosa anastomosis.

Results

The postoperative course was uneventful and, 20 months later (39 months post-LSG), the patient is well with a BMI of 27.

Conclusions

Laparoscopic apposition of a Roux-en-Y limb without mucosa-to-mucosa anastomosis as an efferent path to drain the undebrided fistula defect can effectively treat chronic leaks at the EGJ after LSG.     

Ratio Between Proximal/Distal Gastroesophageal Reflux Does Not Discriminate Abnormal Proximal Reflux

Introduction

The threshold for pathologic proximal acid reflux is a controversial topic. Most values previously published are based on absolute numbers. We hypothesized that a relative value representing the quantitative relation between the amount of acid reflux that reaches proximal levels and the amount of distal reflux would be a more adequate parameter for defining pathologic proximal reflux.

Methods

We studied 20 healthy volunteers (median age 30 years, 70 % women) without gastroesophageal reflux disease (GERD); 50 patients (median age 51 years, 60 % women) with esophageal symptoms of GERD (heartburn, regurgitation); and 50 patients (median age 49 years, 60 % women) with extra-esophageal symptoms of GERD. All individuals underwent manometry and dual-probe pH monitoring. GERD was defined as a DeMeester score >14.7. The proximal/distal reflux ratio was calculated for all six parameters that constitute the DeMeester score.

Results

Absolute numbers for proximal reflux were not different for the three groups except for the number of episodes of reflux, which was higher for patients with GERD and esophageal symptoms than for patients with GERD and extra-esophageal symptoms (p = 0.007). The number of episodes of distal reflux reaching proximal levels was significantly higher in volunteers than in all patients with GERD and significantly higher in patients with GERD and esophageal symptoms than in those with extra-esophageal symptoms.

Conclusions

Our results suggest that the proximal/distal reflux ratio is not a good normative value for defining proximal reflux.     

Embedded Cervical Esophagogastrostomy: A Simple and Convenient Method Using a Circular Stapler After Esophagectomy for Esophageal Carcinomas

Background

Cervical esophagogastrostomy is currently the most common method for esophageal reconstruction after esophagectomy. The advantages and disadvantages of hand-sewn, linear-stapled, or circular-stapled anastomoses have been subject to debate in recent years. We explored a new method of end-to-side anastomosis using a circular stapler that embeds the anastomosis and the remaining esophageal tissue into the gastric cavity to reduce the occurrence of anastomotic leakage and to prevent gastroesophageal reflux.

Methods

In 127 patients with esophageal carcinomas, end-to-side anastomoses with esophageal embedding were performed by connecting the anvil and body of the circular stapler inside the stomach before firing and embedding the anastomosis and remaining esophagus into the stomach after esophagectomy. Retrospective investigations on postoperative complications such as leakage, stricture, and gastroesophageal reflux were conducted.

Results

A total of 123 patients (96.9 %) had successful surgery, and 4 patients (3.3 %) developed anastomotic leakage, with the total morbidity of 20 of 123 (16.3 %) and in-hospital mortality of 1 of 123 (0.8 %). The incidence of stricture (<1 cm) affected 14 of 123 patients (11.4 %). Eight patients underwent dilatation treatment as a result of severe dysphagia (6.5 %). Half of the patients [62 of 123 (50.4 %)] experienced postoperative heartburn, 11 of 123 patients (8.9 %) experienced acid regurgitation, and 16 of 123 patients (13.0 %) experienced nocturnal cough.

Conclusions

Embedded cervical esophagogastrostomy with circular stapler is a simple and convenient method, with low incidence of anastomotic leakage and a good antireflux effect.     

Laparoscopy-assisted Proximal Gastrectomy with Sentinel Node Mapping for Early Gastric Cancer

Background

Laparoscopy-assisted proximal gastrectomy (LAPG) remains a relatively uncommon procedure because of certain technical issues, such as curability, safety, and retention of postoperative patients?? quality of life. The aim of the present study was to evaluate the feasibility of a newly developed LAPG procedure for early-stage proximal gastric cancer.

Methods

We enrolled 37 consecutive patients who were preoperatively diagnosed with cT1N0M0 primary gastric cancer in the upper third of the stomach with the primary tumor diameter less than 4?cm. Laparoscopy-assisted proximal gastrectomy with sentinel node (SN) mapping and esophagogastric anastomosis with a circular stapler and transoral placement of the anvil was attempted.

Results

The LAPG procedure was completed in 36 patients. It was converted to laparoscopy-assisted total gastrectomy in one patient because one SN detected intraoperatively was positive for metastasis by intraoperative pathological diagnosis. There were no severe postoperative complications in any patient. Only one patient (3%) complained of mild reflux symptoms immediately after operation, which were graded endoscopically as B by the Los Angeles Classification of gastroesophageal reflux disease; however, the symptoms were controlled well by a proton-pump inhibitor. Sentinel nodes were detected successfully in 37 (100%) of our patients. The mean number of dissected lymph nodes and identified SNs per case was 29.7 and 5.8, respectively. The sensitivity of prediction of nodal metastasis (including isolated tumor cells) and diagnostic accuracy based on SN status were 100% (3/3) and 100% (37/37), respectively. All patients have been free from recurrence for a median follow-up period of 26?months.

Conclusions

This study reveals that our novel LAPG approach is curative and represents a feasible minimally invasive surgical procedure with minimal morbidity and postoperative reflux esophagitis in patients with upper-third early-stage gastric cancer.     

Laparoscopic antireflux surgery improves esophageal body motility in patients with severe reflux esophagitis

Purpose

This study was designed to clarify whether laparoscopic antireflux surgery (LARS) improves the esophageal body motility (EBM) in patients with reflux esophagitis.

Methods

Thirty-five patients with gastroesophageal reflux disease (GERD) scheduled to undergo LARS were divided into a mild esophagitis group (ME; n = 18, Grade O:A:B = 7:10:1) and a severe esophagitis group (SE; n = 17, Grade C:D = 13:4), according to the Los Angeles classification of reflux esophagitis. The types of fundoplication (Nissen/Toupet) were 6/12 in the ME group and 4/13 in the SE group. Esophageal pH monitoring and manometry were performed before and 1 year after surgery.

Results

The fraction time of a pH below 4 significantly decreased after surgery in both groups. The LES pressures did not change significantly after surgery in the ME group, but significantly increased in the SE group. The peristaltic amplitudes 18 and 13 cm above the LES did not change significantly after surgery in either group. The peristaltic amplitudes 8 and 3 cm above the LES did not change significantly after surgery in the ME group, but significantly increased after surgery in the SE group.

Conclusions

The preoperative EBM was not improved by LARS in patients with GERD and mild mucosal breaks in the esophagus, but the preoperative middle to distal EBM was improved by LARS in patients with GERD and severe mucosal breaks.
