Objectives:To explore the Clavien-Dindo (CD) classfication of short-term (within 30 days postoperative) complications of distal major gastrectomy (DG) and the associated risk factors affecting this classification.Methods:A retrospective analysis was conducted on the clinical data of 230 patients with gastric cancer who underwent DG completed by the same operator at Beijing Friendship Hospital, Capital Medical University from January 2016 to December 2021. There were 159 males (69.1%) and 71 females (30.9%), aged from 31 to 80 years, with an average age of (61.69±10.91) years, all patients average body mass index was (23.59±3.46) kg/m 2. Chi-square test or Fisher exact probability method was used to compare the count data between groups, and rank sum test was used to compare the rank data between groups. Multiple factors were analyzed by stepwise Logistic regression. Results:In this study, a total of 30 cases (13.0%) experienced CD grade Ⅱ or higher postoperative complications. Among them, 20 cases (66.7%) were grade Ⅱ, 8 cases (26.7%) were grade Ⅲ, and 2 cases (6.6%) were grade Ⅳ, Among the 30 patients with complications, there were 2 cases of simple anastomotic leakage, 2 cases of anastomotic bleeding, 3 cases of duodenal stump leakage, 2 cases of intra-abdominal infection, 6 cases of intestinal obstruction, 5 cases of pulmonary infection, 2 cases of incision infection, 2 cases of delayed gastric emptying, 3 cases of pulmonary infection combined with atelectasis, 2 cases of anastomotic leakage combined with intra-abdominal infection, and 1 case of pulmonary infection and intra-abdominal infection combined with intestinal obstruction. Pulmonary infection, intestinal obstruction, and anastomotic leakage were the main postoperative complications of DG. The surgical approach was an independent risk factor for postoperative complications ( P<0.05), and there was no statistically significant difference in the grade of postoperative complications of patients with different surgical methods( P>0.05). Conclusions:Pulmonary infection, intestinal obstruction, abdominal infection, and anastomotic leakage are the main postoperative complications of DG. The independent risk factor for complications is the surgical approach, but the surgical approach does not affect the CD grading of complications.

Objective:To investigate the short-term efficacy of left-sided three-port total laparoscopic distal gastrectomy (TPTLDG).Methods:The prospective randomized controlled study was conducted. The 68 patients undergoing laparoscopic distal gastrectomy in the First Affiliated Hospital of Air Force Medical University from March 2022 to March 2023 were collected. All patients were randomly assigned to the TPTLDG group with a double number, and to the five-port laparoscopic distal gastrectomy (FPLDG) group with a single number, respectively. Observation indicators: (1) grouping situations of the enrolled patients; (2) comparison of perioperative condition; (3) comparison of complications during postoperative 30 days; (4) comparison of pathological examination. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or continuous correction chi-square test. Comparison of ordinal data was analyzed using the non‐parameter rank sum test. Results:(1) Grouping situations of the enrolled patients. A total of 59 patients of gastric cancer were selected for eligibility. There were 40 males and 19 females, aged 59.00(52.00, 67.00)years.

Objective:To investigate the application value of manual anastomosis of gastro-duodenum in totally laparoscopic distal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 55 patients with gastric cancer who underwent totally laparoscopic distal gastrectomy combined with gastrointestinal anastomosis in the Tianjin Medical University Cancer Institute & Hospital from January 2020 to October 2022 were collected. There were 34 males and 21 females, aged 61(range, 29?75)years. Of 55 patients, 25 patients undergoing manual anastomosis of gastroduodenum were divided into the manual anastomosis group, 30 patients undergoing modified Delta anastomosis of gastroduodenum were divided into the modified Delta anastomosis group. Observation indicators: (1) surgical situations; (2) postoperative complications. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using chi-square test or Fisher exact probility. Results:(1) Surgical situations. All 55 patients underwent surgery successfully, without conversion to laparotomy. The distance from the superior margin of tumor to the upper margin, anastomosis time, number of bookings used were (48±4)mm, (22.6±2.3)minutes, 3.2±0.5 in the manual anastomosis group, versus (41±4)mm, (14.0±1.4)minutes, 5.2±0.4 in the modified Delta anastomosis group, showing significant differences in the above indicators between the two groups ( t=5.04, 16.38, ?17.13, P<0.05). The location of tumor (antrum, gastric angle) was 18, 7 in the manual anastomosis group, versus 29, 1 in the modified Delta anastomosis group, showing a significant difference between the two groups ( P<0.05). (2) Postoperative complications. There was no patient undergoing anastomotic fistula in both of manual anastomosis group and modified Delta anastomosis group, and there was 1 patient undergoing anastomotic stenosis in the modified Delta anastomosis group. Conclusion:Compared with modi-fied Delta anastomosis of gastroduodenum,totally laparoscopic distal gastrectomy with manual anas-tomosis of gastroduodenum can remove more gastric tissue, and decrease the number of bookings used.

There were 442 males and 210 females, aged (57±12)years. All patients underwent laparoscopic D 2 radical distal gastrectomy. Observation indicators: (1) surgical situations; (2) postoperative pathological examination; (3) postoperative recovery and complications; (4) follow-up; (5) prognostic factors analysis. Follow-up was conducted by outpatient examination and telephone interview to detect the tumor recurrence and metastasis, postoperative survival of patients up to March 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers or percen-tages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was analyzed using the rank sum test. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-Rank test was used for survival analysis. Univariate and multivariate analyses were analyzed using the COX hazard regression model. Results:(1) Surgical situations: among 652 patients, 617 cases underwent D 2 lymph node dissection and 35 cases underwent D 2+ lymph node dissection. There were 348 cases with Billroth Ⅱ anastomosis, 218 cases with Billroth Ⅰ anastomosis, 25 cases with Roux-en-Y anastomosis and 61 cases with other digestive tract reconstruction methods. Twelve patients had combined visceral resection. There were 569 patients with intraoperative blood transfusion and 83 cases without blood transfusion. The operation time of 652 patients was 187(155,240)minutes and volume of intraoperative blood loss was 100(50,150)mL. (2) Postoperative pathological examina-tion: the maximum diameter of tumor was (4.5±2.0)cm of 652 patients. The number of lymph node dissected of 652 patients was 26(19,35), in which the number of lymph node dissected was >15 of 570 cases and ≤15 of 82 cases. The number of metastatic lymph node was 4(1,9). The proximal tumor margin was (4.8±1.6)cm and the distal tumor margin was (4.5±1.5)cm. Among 652 patients, 255 cases were classified as Borrmann type Ⅰ-Ⅱ, 334 cases were classified as Borrmann type Ⅲ-Ⅳ, and 63 cases had missing Borrmann classification data. The degree of tumor differentiation was high or medium in 171 cases, low or undifferentiated in 430 cases, and the tumor differentiation data was missing in 51 cases. There were 123, 253 and 276 cases in pathological stage T2, T3 and T4a, respectively. There were 116, 131, 214 and 191 cases in pathological stage N0, N1, N2 and N3, respectively. There were 260 and 392 cases in pathological TNM stage Ⅱ and Ⅲ, respectively. (3) Postoperative recovery and complications: the time to postoperative first out-of-bed activities, time to postoperative first flatus, time to the initial liquid food intake, duration of postoperative hospital stay of 652 patients were 3(2,4)days, 4(3,5)days, 5(4,6)days, 10(9,13)days, respectively. Among 652 patients, 69 cases had postoperative complications. Clavien-Dindo grade Ⅰ-Ⅱ, grade Ⅲa, grade Ⅲb, and grade Ⅳa complications occurred in 60, 3, 5 and 1 cases, respectively (some patients could have multiple complications). The duodenal stump leakage was the most common surgical complication, with the incidence of 3.07%(20/652). Respiratory complication was the most common systemic complication, with the incidence of 2.91%(19/652). All the 69 patients were recovered and discharged successfully after treatment. (4) Follow-up: 652 patients were followed up for 110-193 months, with a median follow-up time of 124 months. There were 298 cases with postoperative recurrence and metastasis. Of the 255 patients with the time to postoperative recurrence and metastasis ≤5 years, there were 21 cases with distant metastasis, 69 cases with peritoneal metastasis, 37 cases with local recurrence, 52 cases with multiple recurrence and metastasis, 76 cases with recurrence and metastasis at other locations. The above indicators were 5, 9, 10, 4, 15 of the 43 patients with the time to postoperative recurrence and metastasis >5 years. There was no significant difference in the type of recurrence and metastasis between them ( χ2=5.52, P>0.05). Cases in pathological TNM stage Ⅱ and Ⅲ were 62 and 193 of the patients with the time to postoperative recurrence and metastasis ≤5 years, versus 23 and 20 of the patients with the time to postoperative recurrence and metastasis >5 years, showing a significant difference in pathological TNM staging between them ( χ2=15.36, P<0.05). Cases in pathological stage T2, T3, T4a were 42, 95, 118 of the patients with the time to postoperative recurrence and metastasis ≤5 years, versus 9, 21, 13 of the patients with the time to postoperative recurrence and metastasis >5 years, showing no significant difference in pathological T staging between them ( Z=-1.80, P>0.05). Further analysis showed no significant difference in cases in pathological stage T2 or T3 ( χ2=0.52, 2.08, P>0.05) but a significant difference in cases in pathological stage T4a between them ( χ2=3.84, P<0.05). Cases in pathological stage N0, N1, N2, N3 were 19, 44, 85, 107 of the patients with the time to postoperative recurrence and metastasis ≤5 years, versus 12, 5, 18, 8 of the patients with the time to postoperative recurrence and metastasis >5 years, showing a significant difference in pathological N staging between them ( Z=-3.34, P<0.05). Further analysis showed significant differences in cases in pathological stage N0 and N3 ( χ2=16.52, 8.47, P<0.05) but no significant difference in cases in pathological stage N1 or N2 ( χ2=0.85, 1.18, P>0.05). The median overall survival time was 81 months after surgery and 10-year overall survival rate was 46.1% of 652 patients. The 10-year overall survival rates of patients in TNM stage Ⅱ and Ⅲ were 59.6% and 37.5%, respectively, showing a significant difference between them ( χ2=35.29, P<0.05). In further analysis, the 10-year overall survival rates of patients in pathological TNM stage ⅡA, ⅡB, ⅢA, ⅢB and ⅢC were 65.6%, 55.8%, 46.9%, 37.1% and 24.0%, respectively, showing a significant difference between them ( χ2=55.06, P<0.05). The 10-year overall survival rates of patients in patholo-gical stage T2, T3 and T4a were 55.2%, 46.5% and 41.5%, respectively, showing a significant difference between them ( χ2=8.39, P<0.05). The 10-year overall survival rates of patients in patholo-gical stage N0, N1, N2 and N3 were 63.7%, 56.2%, 48.5% and 26.4%, respectively, showing a signifi-cant difference between them ( χ2=54.89, P<0.05). (5) Prognostic factors analysis: results of univariate analysis showed that age, maximum diameter of tumor, degree of tumor differentiation as low or undifferentiated, pathological TNM staging, pathological T staging, pathological stage N2 or N3, post-operative chemotherapy were related factors for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparoscopic D 2 radical distal gastrectomy ( hazard ratio=1.45, 1.64, 1.37, 2.05, 1.30, 1.68, 3.08, 0.56, 95% confidence interval as 1.15-1.84, 1.32-2.03, 1.05-1.77, 1.62-2.59, 1.05-1.61, 1.17-2.42, 2.15-4.41, 0.44-0.70, P<0.05). Results of multivariate analysis showed that maximum diameter of tumor >4 cm, low-differentiated or undifferentiated tumor, pathological TNM stage Ⅲ were independent risk factors for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparoscopic D 2 radical distal gastrectomy ( hazard ratio=1.48,1.44, 1.81, 95% confidence interval as 1.19-1.84, 1.11-1.88, 1.42-2.30, P<0.05) and postoperative chemotherapy was a independent protective factor for the 10-year overall survi-val rate of locally advanced gastric cancer patients undergoing laparoscopic D 2 radical distal gastrec-tomy ( hazard ratio=0.57, 95% confidence interval as 045-0.73, P<0.05). Conclusions:Laparoscopic assisted D 2 radical distal gastrectomy for locally advanced gastric cancer has satisfactory 10-year oncologic outcomes. A high proportion of patients in pathological TNM stage Ⅲ, pathological stage T4a, pathological stage N3 have the time to postoperative recurrence and metastasis ≤5 years, whereas a high proportion of patients in pathological TNM stage Ⅱ or pathological stage N0 have the time to postoperative recurrence and metastasis >5 years. Maximum diameter of tumor >4 cm, low-differentiated or undifferentiated tumor, pathological TNM stage Ⅲ are independent risk factors for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparos-copic D 2 radical distal gastrectomy. Postoperative chemotherapy is a independent protective factor for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparos-copic D 2 radical distal gastrectomy.

Objective: To compare the clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer patients. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) 18 to 75 years old; (2) gastric cancer proved by preoperative gastroscopy, CT and pathological results and tumor was suitable for D2 radical distal gastrectomy; (3) postoperative pathological diagnosis stage was T1-4aN0-3M0 (according to the AJCC-7th TNM tumor stage), and the margin was negative; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, and American Association of Anesthesiologists (ASA) grade 1 to 3; (5) no mental illness; (6) able to answer questionnaires independently; (7) patients agreed to undergo laparoscopic distal gastrectomy and signed an informed consent. Exclusion criteria: (1) patients with severe chronic diseases and American Association of Anesthesiologists (ASA) grade >3; (2) patients with other malignant tumors; (3) patients suffered from serious mental diseases; (4) patients received neoadjuvant chemotherapy or immunotherapy. According to the above criteria, clinical data of 200 patients who underwent laparoscopic distal gastrectomy at the Department of General Surgery of the First Affiliated Hospital of Army Medical University from January 2016 to December 2019 were collected. Of the 200 patients, 108 underwent uncut Roux-en-Y anastomosis and 92 underwent Billroth II with Braun anastomosis. The general data, intraoperative and postoperative conditions, complications, and endoscopic evaluation 1 year after the surgery were compared. Besides, the quality of life of two groups was also compared using the Chinese version of the European Organization For Research and Treatment of Cancer (EORTC) quality of life questionnaire-Core 30 (QLQ-C30) and quality of life questionnaire-stomach 22 (QLQ-STO22). Results: There were no significant differences in baseline data between the two groups (all P>0.05). All the 200 patients successfully underwent laparoscopic distal gastrectomy without intraoperative complications, conversion to open surgery or perioperative death. There were no significant differences between two groups in operative time, intraoperative blood loss, postoperative complications, time to flatus, time to removal of gastric tube, time to liquid diet, time to removal of drainage tube or length of postoperative hospital stay (all P>0.05). Endoscopic evaluation was conducted 1 year after surgery. Compared to Billroth II with Braun group, the uncut Roux-en-Y group had a significantly lower incidences of gastric stasis [19.8% (17/86) vs. 37.0% (27/73), χ(2)=11.199, P=0.024], gastritis [11.6% (10/86) vs. 34.2% (25/73), χ(2)=20.892, P<0.001] and bile reflux [1.2% (1/86) vs. 28.8% (21/73), χ(2)=25.237, P<0.001], and the differences were statistically significant. The EORTC questionnaire was performed 1 year after surgery, there were no significant differences in the scores of QLQ-C30 scale between the two groups (all P>0.05), while the scores of QLQ-STO22 showed that, compared to the Billroth II with Braun group, the uncut Roux-en-Y group had a lower pain score (median: 8.3 vs. 16.7, Z=-2.342, P=0.019) and reflux score (median: 0 vs 5.6, Z=-2.284, P=0.022), and the differences were statistically significant (all P<0.05), indicating milder symptoms. Conclusion: The uncut Roux-en-Y anastomosis is safe and reliable in laparoscopic distal gastrectomy, which can reduce the incidences of gastric stasis, gastritis and bile reflux, and improve the quality of life of patients after surgery.

Objective: The pattern of digestive tract reconstruction in radical gastrectomy for gastric cancer is still inconclusive. This study aims to compare mid-term and long-term quality of life after radical gastrectomy for distal gastric cancer between Billroth-I (B-I) and Billroth-II (B-II) reconstruction. Methods: A retrospective cohort study was conducted.Clinicopathological and follow-up data of 859 gastric cancer patients were colected cellected from the surgical case registry database of Gastrointestinal Surgery Center of Sichuan University West China Hospital, who underwent radical distal gastric cancer resection between January 2016 and December 2020. Inclusion criteria: (1) gastric cancer confirmed by preoperative gastroscopy and biopsy; (2) elective radical distal major gastrectomy performed according to the Japanese Society for Gastric Cancer treatment guidelines for gastric cancer; (3) TNM staging referenced to the American Cancer Society 8th edition criteria and exclusion of patients with stage IV by postoperative pathology; (4) combined organ resection only involving the gallbladder or appendix; (5) gastrointestinal tract reconstruction modality of B-I or B-II; (6) complete clinicopathological data; (7) survivor during the last follow-up period from December 15, 2021 to January 15, 2022. Exclusion criteria: (1) poor compliance to follow-up; (2) incomplete information on questionnaire evaluation; (3) survivors with tumors; (4) concurrent malignancies in other systems; (5) concurrent psychiatric and neurological disorders that seriously affected the objectivity of the questionnaire or interfered with patient's cognition. Telephone follow-up was conducted by a single investigator from December 2021 to January 2022, and the standardized questionnaire EORTC QLQ-C30 scale (symptom domains, functional domains and general health status) and EORTC QLQ-STO22 scale (5 symptoms of dysphagia, pain, reflux, restricted eating, anxiety; 4 single items of dry mouth, taste, body image, hair loss) were applied to evaluate postoperative quality of life. In 859 patients, 271 were females and 588 were males; the median age was 57.0 (49.5, 66.0) years. The included cases were divided into the postoperative follow-up first year group (202 cases), the second year group (236 cases), the third year group (148 cases), the fourth year group (129 cases) and the fifth year group (144 cases) according to the number of years of postoperative follow-up. Each group was then divided into B-I reconstruction group and B-II reconstruction group according to procedure of digestive tract reconstruction. Except for T-stage in the fourth year group, and age, tumor T-stage and tumor TNM-stage in the fifth year group, whose differences were statistically significant between the B-I and B-II reconstruction groups (all P<0.05), the differences between the B-I and B-II reconstruction groups in terms of demographics, body mass index (BMI), tumor TNM-stage and tumor pathological grading in postoperative follow-up each year group were not statistically significant (all P>0.05), suggesting that the baseline information between B-I reconstruction group and the B-II reconstruction group in postoperative each year group was comparable. Evaluation indicators of quality of life (EORTC QLQ-C30 and EORTC QLQ-STO22 scales) and nutrition-related laboratory tests (serum hemoglobin, albumin, total protein, triglycerides) between the B-I reconstruction group and B-II reconstruction group in each year group were compared. Non-normally distributed continuous variables were presented as median (Q(1),Q(3)), and compared by using the Wilcoxon rank sum test (paired=False). The χ(2) test or Fisher's exact test was used for comparison of categorical variables between groups. Results: There were no statistically significant differences in all indexes EORTC QLQ-30 scale between the B-I reconstruction group and the B-II reconstruction group among all postoperative follow-up year groups (all P>0.05). The EORTC QLQ-STO22 scale showed that significant differences in pain and eating scores between the B-I reconstruction group and the B-II reconstruction group were found in the second year group, and significant differences in eating, body and hair loss scores between the B-I reconstruction group and the B-II reconstruction group were found in the third year group (all P<0.05), while no significant differences of other item scores between the B-I reconstruction group and the B-II reconstruction group were found in postoperative follow-up of all year groups (P>0.05). Triglyceride level was higher in the B-II reconstruction group than that in the B-I reconstruction group (W=2 060.5, P=0.038), and the proportion of patients with hyperlipidemia (triglycerides >1.85 mmol/L) was also higher in the B-II reconstruction group (19/168, 11.3%) than that in the B-I reconstruction group (0/34) (χ(2)=0.047, P=0.030) in the first year group with significant difference. Albumin level was lower in the B-II reconstruction group than that in the B-I reconstruction group (W=482.5, P=0.036), and the proportion of patients with hypoproteinemia (albumin <40 g/L) was also higher in the B-II reconstruction group (19/125, 15.2%) than that in the B-I reconstruction group (0/19) in the fifth year group, but the difference was not statistically significant (χ(2)=0.341, P=0.164). Other nutrition-related clinical laboratory tests were not statistically different between the B-I reconstruction and the B-II reconstruction in each year group (all P>0.05). Conclusions: The effects of both B-I and B-II reconstruction methods on postoperative mid-term and long-term quality of life are comparable. The choice of reconstruction method after radical resection of distal gastric cancer can be based on a combination of patients' condition, sugenos' eoperience and operational convenience.

Lipoma is a rare mesenchymal tumour of stomach (less than 1% of gastric tumours) to present as gastrointestinal bleed. We report a case of upper gastrointestinal bleed from a gastric lipoma in a 42 year male patient who underwent distal gastrectomy for resection of the large submucosal tumour situated in antropyloric region. Most common age of presentation of gastric lipoma is fifth or sixth decade of life and most of these are located in submucosal plane (90% cases) and in antropyloric region (75% cases). Gastric lipomas can be diagnosed by endoscopic means but most often with CT scan which shows characteristic fat attenuation. Small asymptomatic incidentally diagnosed can be safely observed while larger symptomatic tumours are treated by endoscopic or surgical resection which offers cure from this benign lesion.

Laparoscopic radical gastrectomy is currently recognized as the standard surgical procedure for radical gastric cancer. The dissection of the sixth group of lymph node, that is the inferior pylorus region lymph node, should be performed step-by-step according to standard procedures, and surgeon on left position of patient is more conducive to the lymph node dissection of this area. The 4K laparoscopic system can increase the resolution of the surgical field of view, which provide the surgeon with a clear surgical field of vision, thereby improving the accuracy of operation, achieving the best requirements of lymph node dissection and avoiding side injury and complica-tions. The authors investigate infrapyloric lymph node dissection with the surgeon on left position in 4K laparoscopic radical gastrectomy.

ABSTRACT Background: Re-fundoplication is the most often procedure performed after failed fundoplication, but re-failure is even higher. Aim: The objectives are: a) to discuss the results of fundoplication and re-fundoplication in these cases, and b) to analyze in which clinical situation there is a room for gastrectomy after failed fundoplication. Method: This experience includes 104 patients submitted to re-fundoplication after failure of the initial operation, 50 cases of long segment Barrett´s esophagus and 60 patients with morbid obesity, comparing the postoperative outcome in terms of clinical, endoscopic, manometric and 24h pH monitoring results. Results: In patients with failure after initial fundoplication, redo-fundoplication shows the worst clinical results (symptoms, endoscopic esophagitis, manometry and 24 h pH monitoring). In patients with long segment Barrett´s esophagus, better results were observed after fundoplication plus Roux-en-Y distal gastrectomy and in obese patients similar results regarding symptoms, endoscopic esophagitis and 24h pH monitoring were observed after both fundoplication plus distal gastrectomy or laparoscopic resectional gastric bypass, while regarding manometry, normal LES pressure was observed only after fundoplication plus distal gastrectomy. Conclusion: Distal gastrectomy is recommended for patients with failure after initial fundoplication, patients with long segment Barrett´s esophagus and obese patients with gastroesophageal reflux disease and Barrett´s esophagus. Despite its higher morbidity, this procedure represents an important addition to the surgical armamentarium.
RESUMO Racional: Re-fundoplicatura é o procedimento mais frequentemente realizado após falha na fundoplicatura, mas neste caso a falha é ainda maior. Objetivo: a) discutir os resultados da fundoplicatura e re-fundoplicatura nesses casos; e b) analisar em que situação clínica há espaço para gastrectomia após falha na fundoplicatura. Método: Esta experiência inclui 104 pacientes submetidos à re-fundoplicatura após falha da operação inicial, sendo 50 casos de esôfago de Barrett de segmento longo e 60 pacientes com obesidade mórbida, comparando-se o resultado pós-operatório em termos de pH clínico, endoscópico, manométrico de 24 h de monitoramento. Resultados: Em pacientes com falha após a fundoplicatura inicial, a re-fundoplicatura mostra os piores resultados clínicos (sintomas, esofagite endoscópica, manometria e pHmetria 24 h). Em pacientes com esôfago de Barrett de segmento longo, melhores resultados foram observados após fundoplicatura com gastrectomia distal em Y-de-Roux e em pacientes obesos resultados semelhantes em relação aos sintomas, esofagite endoscópica e monitoramento de pH 24 h foram observados após fundoplicatura com gastrectomia distal ou ressecção com bypass gástrico laparoscópico, enquanto que em relação à manometria, a pressão normal do EEI só foi observada após a fundoplicatura e gastrectomia distal. Conclusão: A gastrectomia distal é recomendada para pacientes com falha após a fundoplicatura inicial, pacientes com esôfago de Barrett de segmento longo e obesos com doença do refluxo gastroesofágico e esôfago de Barrett. Apesar de sua maior morbidade, esse procedimento representa um importante acréscimo ao arsenal cirúrgico.

BACKGROUND: Billroth I anastomosis is one of the most common reconstruction methods after distal gastrectomy for gastric cancer. Intracorporeal Billroth I (ICBI) anastomosis and extracorporeal Billroth I (ECBI) anastomosis are widely used in laparoscopic surgery. Here we compared ICBI and ECBI outcomes at a major gastric cancer center. METHODS: We retrospectively analyzed data from 2,284 gastric cancer patients who underwent laparoscopic distal gastrectomy between 2009 and 2017. We divided the subjects into ECBI (n=1,681) and ICBI (n=603) groups, compared the patients’ clinical characteristics and surgical and short-term outcomes, and performed risk factor analyses of postoperative complication development. RESULTS: The ICBI group experienced shorter operation times, less blood loss, and shorter hospital stays than the ECBI group. There were no clinically significant intergroup differences in diet initiation. Changes in white blood cell counts and C-reactive protein levels were similar between groups. Grade II–IV surgical complication rates were 2.7% and 4.0% in the ECBI and ICBI groups, respectively, with no significant intergroup differences. Male sex and a body mass index (BMI) ≥30 were independent risk factors for surgical complication development. In the ECBI group, patients with a BMI ≥30 experienced a significantly higher surgical complication rate than those with a lower BMI, while no such difference was observed in the ICBI group. CONCLUSION: The surgical safety of ICBI was similar to that of ECBI. Although the chosen anastomotic technique was not a risk factor for surgical complications, ECBI was more vulnerable to surgical complications than ICBI in patients with a high BMI (≥30).

Objective@#The aim of the current study is to compare the short-term clinical outcomes between Billroth-I reconstruction using an overlap method and delta-shaped anastomosis in totally laparoscopic distal gastrectomy (TLDG).@*Method@#A retrospective cohort study was performed. The following inclusion criteria were applied: (1) Preoperative gastroscopy and CT confirmed that the tumor is located in the antrum of the stomach, and the biopsy suggested adenocarcinoma; (2) Chest, abdomen and pelvis enhanced CT showed no evidence of distant metastasis; (3) Preoperative gastric reconstruction CT or endoscopic ultrasonography suggested that the clinical stage of the tumor is stage I-III. (4) During the operation, the tumor position was confirmed to be located in the antrum of the stomach by nanocarbon injection or gastroscope; (5) Complete laparoscopic radical gastrectomy for distal gastrectomy, and the gastrointestinal reconstruction was performed by delta-shaped anastomosis or overlap anastomosis. And the following exclusion criteria were applied: (1) History of gastric surgery; (2) Patients who cannot tolerate laparoscopic surgery because of comorbidities. Finally, data on 43 consecutive patients who underwent TLDG with Billroth-I reconstruction between January 2016 and November 2018 in Peking Union Medical College Hospital were retrospectively reviewed. Patients were divided into those who underwent Billroth-I reconstruction using an overlap method (n=20) or using delta-shaped anastomosis (n=23). The demographic and clinical characteristics and perioperative data of the two groups were analyzed. Measurement data that conformed to the normal distribution were expressed as the mean ± s, and differences between groups were compared using Student′s t-test; comparisons between the counting data groups were performed using the χ2 test or the continuously corrected χ2 test.@*Results@#The demographic and clinical characteristics were similar between the delta-shaped group and the overlap group (P>0.05). There was no significant difference between groups regarding operation time [(185.9±22.8) minutes vs. (184.0±25.8) minutes, t=0.260, P=0.796], blood loss [(50.9±36.0) ml vs. (47.0±30.8) ml, t=0.375, P=0.709], number of stapler reloads used for anastomosis (5.1±0.3 vs. 5.2±0.6, t=-0.465, P=0.651), time to flatus [(3.3±0.9) days vs. (3.6±0.9) days, t=-1.067, P=0.292) and postoperative hospitalization [(8.8±3.1) days vs. (10.4±3.8) days,t=-1.494, P=0.143]. As for the delta-shaped group and the overlap group, the anastomotic leakage rate was 4.3% (1/23) and 0 (χ2=0.000, P=1.000), respectively. The incidence of anastomotic bleeding was 4.3% (1/23) and 5.0% (1/20) (χ2=0.000, P=1.000), while the incidence of intra-abdominal hemorrhage was 4.3% (1/23) and 0 (χ2=0.000, P=1.000). The incidence of gastric emptying disorders was 4.3% (1/23) and 30.0% (6/20), respectively (χ2=3.454, P=0.063). All complications were cured after conservative treatment or symptomatic treatment.@*Conclusion@#The overlap method for Billroth-I reconstruction is safe and feasible.

Objective@#To assess the safety, feasibility and short-term outcome of totally laparoscopic distal gastrectomy(TLDG).@*Methods@#Seventy-five patients who underwent laparoscopic distal gastrectomy in Cancer Hospital of Chinese Academy of Medical Science between August 2015 and April 2018 were enrolled in this study. A total of 46 laparoscopy-assisted distal gastrectomy (LADG) cases and 29 TLDG cases were included. The Short-term outcomes and safeties of the two groups were compared.@*Results@#The operation time of TLDG group was significantly longer than that of LADG group (207±41 vs. 156±34 min, P<0.001), while the length of wound was shorter in the TLDG group (3.6±0.6 vs. 5.8±0.8 cm, P<0.001). The time to first flatus in TLDG group was (3.3±0.6) days, significantly shorter than (3.7±0.8) days in LADG group (P=0.034). There were no significant differences between the two groups in the estimated blood loss, intraoperative blood transfusion, extraction of gastric tube, drainage tube removal, interval of the first time to eat semi-liquid food, postoperative hospital stays, surgical complications, number of retrieved lymph nodes, proximal and distal resection margin lengths (all P>0.05). The white blood cell count at postoperative day 1 in the TLDG group was (10.96±1.96) ×109/L, significantly lower than (12.49±3.46)×109/L of the LADG group (P=0.017). While the CRP level at postoperative day 1 in the TLDG group were lower than that of LADG group, no statistical difference was observed (P=0.072).@*Conclusions@#Our study shows that TLDG is safe and feasible. TLDG has better cosmesis, less blood loss, and faster recovery compared to LADG.

Objective@#To investigate the application value of Overlap anastomosis in Billroth I digestive tract reconstruction after laparoscopic distal gastrectomy in gastric cancer.@*Methods@#Clinical data of 68 stage T1-2 gastric cancer patients undergoing laparoscopic distal gastrectomy for D2 radical gastrectomy from January 2015 to January 2016 at China Japan Union Hospital of Jilin University were retrospectively analyzed. Inclusion criteria: (1) no distant metastasis of gastric cancer confirmed by gastroscopy and pathology before surgery; (2) T1-2 tumor with diameter <3 cm; (3) the lesion locating in the antrum of the stomach with distance >1 cm from the pylorus, and no invasion into middle area; (4) R0 resection confirmed by postoperative pathology; (5) no history of abdominal surgery. Among 68 cases,23 cases were in Overlap anastomosis group and 45 cases in Billroth I anastomosis group. D2 lymph node dissection and distal gastrectomy were performed in both groups. In the Overlap anastomosis group, the duodenum and stomach were severed by a linear stapler under endoscopy, and the residual gastric curve anastomotic opening was selected. According to the tension between the duodenum and the remnant stomach, the anastomotic opening was selected at the upper edge of the remnant duodenum, and the anastomosis between the posterior wall of the remnant stomach and the upper wall of the duodenum was completed by placing the stapler under endoscopy. Then the common opening was closed and the remnant duodenum was resected. In the traditional Billroth I anastomosis group, pneumoperitoneum was discontinued after amputation of the duodenum under laparoscopy. The median incision of the upper abdomen was 9-12 cm. The distal stomach was pulled out to complete the excision of specimens, the extraction of specimens and Billroth I digestive tract reconstruction. The intraoperative and postoperative conditions of the two groups were compared with student t test (continuous variable) and chi-square test (categorica variable).@*Results@#Of the 68 patients,39 were males and 29 were females,with age of (65.5±10.2)(51 to 77)years. Differences in baseline data between Overlap group and Billroth I group were not statistically significant (all P>0.05). Laparoscopic surgery was successfully performed in both groups without conversion to open operation. As compared with the Billroth I group, the Overlap group had significantly shorter operation time [(149.8±10.1) minutes vs. (169.8±15.3) minutes, t=5.658,P=0.008], shorter anastomotic time of digestive tract reconstruction [(31.2±3.8) minutes vs. (36.3±3.3) minutes, t=3.389, P=0.003] and shorter abdominal incision length [(4.5±0.9) cm vs.(11.0±2.3) cm, t=13.244,P=0.004]. There were no significant differences between two groups in intraoperative blood loss [(92.9±22.4) ml vs. (87.0±7.3) ml,t=1.186,P=0.366], number of lymph node dissected (28.4±5.7 vs. 27.3±5.2, t=0.838, P=0.383), postoperative flatus time [(4.4±2.1) days vs.(4.2±1.8) days, t=0.391, P=0.563], morbidity of postoperative complication [4.3%(1/23) vs. 6.7%(3/45), χ2=0.148,P=0.701]. All the patients were followed up for 28±10 (10-46) months. There were no long-term complications, recurrence or death in two groups.@*Conclusion@#Overlap anastomosis in Billroth I digestive tract reconstruction after laparoscopic distal gastrectomy is safe and effective, and can reduce the anastomosis time.

PURPOSE: We aimed to evaluate the clinical outcomes and determine the degree of postoperative pain associated with the location of mini-laparotomy sites in gastric cancer patients who underwent laparoscopic-assisted distal gastrectomy (LADG) or totally laparoscopic distal gastrectomy (TLDG). METHODS: Between November 2011 and December 2016, 153 patients who underwent surgery for gastric cancer at Kyung Hee University Hospital at Gangdong were reviewed retrospectively. We divided the patients into LADG with epigastric incision, TLDG with umbilical incision (TLDG_U), and TLDG with Pfannenstiel incision (TLDG_P) groups according to the location of incision for anastomosis and specimen removal. There were 37 cases in the LADG group, 85 in the TLDG_U group, and 31 in the TLDG_P group. The clinical characteristics, numeric rating scale (NRS) scores, and postoperative analgesic usage for 7 days of the three groups were compared. RESULTS: There was no statistically significant difference in clinical characteristics including age, sex, body mass index (BMI), TNM staging, and complications among the three groups. There was no significant difference in the amount of total analgesics received; however, the TLDG_P group received more analgesics (5.26±5.053, p=0.412) during the first 7 postoperative days. The TLDG_P group showed higher NRS scores on postoperative days 0, 2, 3, 4, and 5 (p=0.04, 0.001, 0.003, 0.006, and 0.002 respectively). CONCLUSION: Laparoscopic distal gastrectomy can be performed through various incision sites for increasing the safety of mini-laparotomy. However, a Pfannenstiel incision was shown to be more painful than other incisions.
