A comparison of the effects of anti-reflux procedures during esophagogastrostomy after proximal gastrectomy on the postoperative quality of life.

PURPOSE: To investigate the postoperative quality of life (QOL) in patients with proximal gastric cancer (PGC) or esophago-gastric junction cancer, a nationwide multi-institutional study (PGSAS NEXT trial) was conducted. METHODS: Patients who had undergone radical resection more than 6 months previously were enrolled from 70 Japanese institutions between July 2018 and June 2020. The Postgastrectomy Syndrome Assessment Scale (PGSAS)-45 questionnaire was distributed to eligible patients, and responses were collected by mail. The main outcome measures of the PGSAS-45 were then calculated and compared. RESULTS: Questionnaires were retrieved from 1950 participants, and data from 300 patients who had undergone a proximal gastrectomy (PG) with esophagogastrostomy for PGC were analyzed. The mean esophageal reflux subscale value was 1.9 among the 276 patients who underwent an anti-reflux procedure, which was significantly better than the mean value (2.6) for the 21 patients who did not undergo an anti-reflux procedure (p = 0.002). The esophageal reflux subscale values were also compared among 3 major anti-reflux procedures: the double-flap technique (N = 153), the pseudo-fornix and/or His angle formation (N = 67), and fundoplication (N = 44); no statistically significant differences were observed. CONCLUSION: An anti-reflux procedure during esophagogastrostomy after PG for PGC is necessary to improve postoperative esophageal reflux symptoms, regardless of the type of procedure. TRIAL REGISTRATION: The PGSAS NEXT study was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; registration number: 000032221).

Optimal Procedures for Double Tract Reconstruction After Proximal Gastrectomy Assessed by Postgastrectomy Syndrome Assessment Scale-45.

BACKGROUND: Although double tract reconstruction after proximal gastrectomy (PGDT) is commonly performed for proximal gastric or esophagogastric junction cancer, the impact of the procedure on postoperative quality of life (QOL) has not been clarified. We aimed to clarify the optimal PGDT procedure in terms of postoperative QOL. METHODS: Postoperative QOL was analyzed in 172 patients who underwent PGDT for proximal gastric cancer and were enrolled in the PGSAS-NEXT study, a multicenter cross-sectional study in Japan (UMIN000032221), in relation to the remnant stomach size, length of interposed jejunum between the esophagojejunostomy (E-J) and jejunogastrostomy (J-G), and size of the J-G. RESULTS: The remnant stomach size was approximately one-third in 13, half in 97, and two-thirds in 60 patients. Dissatisfaction scores for symptoms, diet, work, and daily life subscales were lower in patients with a larger stomach (p < 0.05). These patients also scored better in terms of weight loss (- 13.5%, - 14.0%, and - 11.2%, respectively) and amount of food ingested per meal (52%, 62%, and 66%). The length of the interposed jejunum was ≤ 10 cm in 62 and ≥ 11 cm in 97 patients. Weight loss (- 11.3% and - 13.8%) and dissatisfaction scores were better in the ≤ 10 cm group (p < 0.05). J-G size was ≤ 5 cm in 27 and ≥ 6 cm in 135 patients. The amount of food ingested (56%, 64%) and dissatisfaction scores were better in the > 6 cm group (p < 0.05). CONCLUSIONS: Larger remnant stomach, shorter length of interposed jejunum, and longer J-G might contribute to better postoperative QOL after PGDT.

Development and Validation of a Symptom-Focused Quality of Life Questionnaire (KOQUSS-40) for Gastric Cancer Patients after Gastrectomy.

PURPOSE: Patients who have undergone gastrectomy have unique symptoms that are not appropriately assessed using currently available tools. This study developed and validated a symptom-focused quality of life (QoL) questionnaire for patients who have received gastrectomy for gastric cancer. MATERIALS AND METHODS: Based on a literature review, patient interviews, and expert consultation by the KOrean QUality of life in Stomach cancer patients Study group (KOQUSS), the initial item pool was developed. Two large-scale developmental studies were then sequentially conducted for exploratory factor analyses for content validity and item reduction. The final item pool was validated in a separate cohort of patients and assessed for internal consistency, test-retest reliability, construct validity, and clinical validity. RESULTS: The initial questionnaire consisted of 46-items in 12 domains. Data from 465 patients at 11 institutions, followed by 499 patients at 13 institutions, were used to conduct item reduction and exploratory factor analyses. The final questionnaire (KOQUSS-40) comprised 40 items within 11 domains. Validation of KOQUSS-40 was conducted on 413 patients from 12 hospitals. KOQUSS-40 was found to have good model fit. The mean summary score of the KOQUSS-40 was correlated with the EORTC QLQ-C30 and STO22 (correlation coefficients, 0.821 and 0.778, respectively). The KOQUSS-40 score was also correlated with clinical factors, and had acceptable internal consistency (> 0.7). Test-retest reliability was greater than 0.8. CONCLUSION: The KOQUSS-40 can be used to assess QoL of gastric cancer patients after gastrectomy and allows for a robust comparison of surgical techniques in clinical trials.

Post-Gastrectomy Complications - An Overview.

Post-gastrectomy complications have been the associated sequelae after curative gastrectomy for long time. They include a conundrum of symptoms ranging from serious metabolic alterations to disorders attributed to mechanical and neural factors after reconstruction of the digestive continuity. Though, with the advancement in the surgical expertise and techniques and shift towards medical and endoscopic management for benign gastro-duodenal ulcer disease, there has been a decline in the incidence of these complications; they continue to raise "red flags" after major oncologic gastric resections. Identification of these symptoms and protocol based management of the same is of utmost importance in the surgical armamentarium of trainees and practicing physicians and surgeons.

Antireflux mucosectomy for managing reflux symptoms in an obese patient post laparoscopic sleeve gastrectomy.

Laparoscopic sleeve gastrectomy (LSG) is an effective treatment modality for obesity. Commonest delayed complication post LSG is gastroesophageal reflux disease (GER). The prevalence of GER among obese patients is higher than normal individuals. Such patients need long term Proton pump inhibitors (PPI) or antireflux procedures to manage reflux. Antireflux mucosectomy (ARMS) uses techniques of endoscopic mucosal resection to treat reflux for PPI refractory GER. However, it can be technically challenging to perform ARMS with a restricted stomach in patients who have undergone LSG. A 40-year-old female, hypertensive who had previously undergone LSG was treated for GER by a multidimensional approach with ARMS utilizing hypotensive anesthesia. The patient underwent the procedure successfully without any complication. She was discharged and at follow up visit, her reflux symptoms had improved and endoscopy was unremarkable. We describe this unusual case which was treated effectively with ARMS.

Impaired Gastrointestinal Function Affects Symptoms and Alimentary Status in Patients After Gastrectomy.

BACKGROUND: Postgastrectomy syndrome (PGS) remains a common complication after gastrectomy that affects patients' quality of life. Although impaired gastrointestinal (GI) function by gastrectomy procedures is thought to be the cause, the precise pathophysiology of PGS is yet to be clarified. AIM: The aim of this study was to investigate relationships between GI function and various symptoms or alimentary status in patients after gastrectomy. METHODS: Fifty-one patients who underwent total or distal gastrectomy at least 1 year previously were studied. All patients replied to a questionnaire that asked presence of symptoms (esophageal reflux, nausea, abdominal pain, early satiation, diarrhea, early dumping general, early dumping abdominal, and late dumping symptoms) and alimentary status (change in body weight, food intake per meal, frequency of meals per day). They also underwent assessment of GI function consisting of gastric emptying study by 13C-acetate breath test to examine reservoir capacity and gastric emptying, and water load drink test to evaluate tolerance to volume loading (TVL). The relationships between GI function and each symptom or alimentary status were examined. RESULTS: The patients with nausea and early dumping general symptoms had significantly smaller reservoir capacity*, the patients with diarrhea and early dumping general symptoms had significantly faster gastric emptying*, and the patients with early satiation and early dumping abdominal symptoms had significantly impaired TVL*. Significant correlations were identified between TVL and body weight changes* or food intake per meal* (* p < 0.05). CONCLUSION: Impaired postoperative GI function was closely related to symptoms or worse alimentary status.

Optimal Roux-en-Y reconstruction after distal gastrectomy for early gastric cancer as assessed using the newly developed PGSAS-45 scale.

PURPOSE: The optimal surgical procedure for distal gastrectomy with Roux-en-Y reconstruction (DGRY) remains to be determined. Recently, a self-report assessment instrument, the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45), was compiled to evaluate symptoms, the living status and the quality of life of patients who have undergone gastrectomy. We used this scale to evaluate procedures used for DGRY. METHODS: The subjects included 475 patients who underwent DGRY for stage IA/IB gastric cancer. We evaluated whether the size of the remnant stomach, length of the Roux limb, reconstruction route and anastomotic procedure affected the patients' symptoms, living status and quality of life assessed using the PGSAS-45. RESULTS: Patients with a residual stomach of more than half had significantly worse esophageal reflux scores than the patients with a smaller residual stomach (P = 0.0462); a residual stomach of one-third or one-fourth was favorable. A shorter length of the Roux limb was shown to be preferable to a longer Roux limb based on the results of the PGSAS-45. In addition, antecolic reconstruction and the anastomotic procedure using a linear stapler were found to be more favorable. CONCLUSIONS: The size of the remnant stomach and the length and route of the Roux limb significantly influence the patient-reported DGRY outcomes.

Evaluation of QOL after proximal gastrectomy using a newly developed assessment scale (PGSAS-45).

BACKGROUND: Proximal gastrectomy with esophagogastrostomy (PGEG) has been widely applied as a comparatively simple method. In this study, we used a questionnaire survey to evaluate the influence of various surgical factors on post-operative quality of life (QOL) after PGEG. METHODS: In this post-gastrectomy syndrome assessment study, we analyzed QOL in 2,368 cases. Among these, 193 had undergone proximal gastrectomy and 115 had undergone PGEG. The Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 is a questionnaire consisting of 45 items, including the SF-8, the Gastrointestinal Symptom Rating Scale (GSRS), and other symptom items seemed to be specific to post-gastrectomy. The 23 symptom items were composed of seven symptom subscales (SS), including esophageal reflux, abdominal pain, and meal-related distress. These seven SS, total symptom score, ingested amount of food per meal, necessity for additional meals, quality of ingestion SS, ability to work, dissatisfaction with symptoms, dissatisfaction with the meal, dissatisfaction with working, dissatisfaction with daily life SS and change in body weight were evaluated as main outcome measures. In PGEG cases, we evaluated the influence on QOL of various surgical factors, such as procedures to prevent gastroesophageal regurgitation and size of the remnant stomach. RESULTS: The scores for esophageal reflux and dissatisfaction with the meal were higher in patients who had not undergone an anti-reflux procedure. In most cases, the preserved remnant stomach was more than two-thirds the size of the pre-operative stomach. When comparing patients with a remnant stomach two-thirds the pre-operative size and those with more than three-quarters, the diarrhea SS and necessity for additional meals scores were lower in the group with more than three-quarters. The indigestion, constipation, and abdominal pain subscales, and the total symptom score, were higher in patients who had not undergone pyloric bougie than in those who had. CONCLUSION: These results indicated that QOL was better in patients with a large remnant stomach. Procedures to prevent gastroesophageal reflux, and the use of pyloric bougie as a complementary drainage procedure, were considered effective ways to reduce the deterioration of QOL.

[State of duodenal patency in patients with postgastrectomy syndromes].

It was analyzed the examination and treatment results of 100 patients who underwent resection of stomach by Billroth-I in case of peptic ulcer. Chronic disorders of duodenal patency were diagnosed in 86% of patients. The main role of chronic disorders of duodenal patency in postgastrectomy syndromes development was proved. There were a combination of reflux gastritis with dumping syndrome in 66.3% of patients, a combination of reflux gastritis with recurrent ulcer in 8.1% of patients. Correction of chronic disorders of duodenal patency is necessary stage in conservative and surgical treatment of postgastrectomy syndromes.

Roux-en-Y gastrojejunostomy after totally laparoscopic distal gastrectomy: comparison with Billorth II reconstruction.

PURPOSE: The purpose of this study was to compare Roux-en-Y (R-Y) reconstruction with Billroth-II (B-II) reconstruction after a totally laparoscopic distal gastrectomy (TLDG). METHODS: Eighty-one consecutive TLDG procedures were performed by a single surgeon and subsequently examined. Postoperative outcomes, clinicopathologic features, and postoperative endoscopic findings between the 2 groups were evaluated and compared. RESULTS: The mean operation time was not significantly higher in the R-Y than in the B-II group (P=0.396). Postoperative hospital stay was longer in the R-Y than in the B-II group (P=0.037). The severities of gastritis and bile reflux were reduced significantly in the R-Y group as compared with that in the B-II group (P<0.001). There was no significant difference in the amount of residual food between the 2 groups. CONCLUSIONS: R-Y reconstruction after TLDG appears to be a safe and feasible procedure, and is associated with a reduced severity of gastritis and bile reflux in the remnant stomach.

Postgastrectomy Syndrome Assessment Scale (PGSAS)-45 and changes in body weight are useful tools for evaluation of reconstruction methods following distal gastrectomy.

BACKGROUND: Billroth-I (BI) and Roux-en-Y (RY) are well-known reconstruction methods that are conducted following distal gastrectomy. However, the relative merits of these 2 methods are not well documented. The newly developed Postgastrectomy Syndrome Assessment Scale (PGSAS)-45 is an integrated questionnaire consisting of 45 items, including 8 items from the 8-Item Short-Form Health Survey (SF-8), 15 items from the Gastrointestinal Symptom Rating Scale, and 22 items selected by gastric surgeons. Postoperative QOL ratings were evaluated for each reconstruction method using PGSAS-45. METHODS: The PGSAS-45 questionnaire was distributed to 2,922 patients who underwent gastrectomies at 52 medical institutions. Among the questionnaires distributed, 2520 (86 %) were retrieved and 2368 (81 %) met eligibility requirements. Statistical analyses were conducted to compare 1,384 of the eligible questionnaires, including responses from patients who underwent BI (n = 909) and RY (n = 475) procedures. RESULTS: BI procedures were associated with significantly longer postoperative periods, a significantly greater size of gastric remnants, and a higher frequency of laparoscopic approaches and celiac branch preservation. Postoperative QOL analysis indicated that BI procedures resulted in significantly lower postoperative weight loss and significantly higher esophageal reflux symptoms than RY procedures. There was no significant difference between the two groups on other outcome measures. CONCLUSIONS: Although weight loss was significantly lower following BI procedures, esophageal reflux symptoms were significantly higher. Either BI or RY procedures may be recommended based on the individual patient's condition after distal gastrectomy. The newly developed QOL questionnaire, PGSAS-45 and changes in body weight proved useful for evaluation of QOL following gastrectomy.

[The substantiation of the method of gastrointestinal reconstruction after the gastric resection].

Functional results of 289 major gastric resections and gastrectomies were analyzed. New methods of the gastrointestinal reconstruction after these procedures. The comparative analysis of immediate and long-term results allowed to work out criteria of choice for the reconstructive procedure. Benefits of the suggested reconstructive techniques demonstrated with the use of modern diagnostic means.

[Acute pancreatitis and afferent loop syndrome. Case report]. / Pancreatitis aguda y síndrome de asa aferente. Reporte de caso.

BACKGROUND: The afferent syndrome loop is a mechanic obstruction of the afferent limb before a Billroth II or Roux-Y reconstruction, secondary in most of case to distal or subtotal gastrectomy. Clinical case: Male 76 years old, with antecedent of cholecystectomy, gastric adenocarcinoma six years ago, with subtotal gastrectomy and Roux-Y reconstruction. Beginning a several abdominal pain, nausea and vomiting, abdominal distension, without peritoneal irritation sings. Amylase 1246 U/L, lipase 3381 U/L. Computed Tomography with thickness wall and dilatation of afferent loop, pancreas with diffuse enlargement diagnostic of acute pancreatitis secondary an afferent loop syndrome. CONCLUSION: The afferent loop syndrome is presented in 0.3%-1% in all cases with Billroth II reconstruction, with a mortality of up to 57%, the obstruction lead accumulation of bile, pancreatic and intestinal secretions, increasing the pressure and resulting in afferent limb, bile conduct and Wirsung conduct dilatation, triggering an inflammatory response that culminates in pancreatic inflammation. The severity of the presentation is related to the degree and duration of the blockage.

Antecedentes: el síndrome de asa aferente se caracteriza por la obstrucción mecánica del asa aferente luego de la reconstrucción tipo Billroth II o en Y de Roux, en la mayoría de los casos secundaria a gastrectomía distal o subtotal. Caso clínico: paciente masculino de 76 años de edad, con antecedentes de: colecistectomía, adenocarcinoma gástrico seis años previos, gastrectomía subtotal y reconstrucción en Y de Roux. Inició con dolor abdominal, náusea y vómito; abdomen distendido, sin datos de irritación peritoneal. Amilasa 1246 U/L, lipasa 3381 U/L. La tomografía computada abdominal mostró dilatación y engrosamiento de la pared del asa aferente y el páncreas con incremento de tamaño. Se le diagnosticó pancreatitis aguda, originada por síndrome de asa aferente. Conclusiones: el síndrome de asa aferente aparece en 0.3 a 1% de los casos de pacientes con reconstrucción Billroth II, a consecuencia de la obstrucción mecánica del asa aferente, con mortalidad incluso de 57%. La obstrucción del intestino aferente por acumulación de secreción biliar, pancreática e intestinal incrementa la presión, que resulta en dilatación del asa aferente de la vía biliar y del conducto de Wirsung, lo que desencadena una respuesta inflamatoria que finaliza en un cuadro de pancreatitis. Su manifestación severa se relaciona con el grado y duración de la obstrucción.

[The role of chronically disordered duodenal patency in the development of post-gastroresection syndrome].

We assessed results of examination and treatment of 100 patients with ulcer disease who had undergone Bilroth-1 stomach resection. Chronic disorder of duodenal patency was revealed in 86% of the patients. This condition was shown to play the leading role in the development of post-gastric resection syndrome. Reflux-gastritis was associated with damping syndrome in 66.3% of the patients and with recurrent ulcer in 8.1%. It is concluded that conservative and surgical treatment of post-gastric resection syndrome should be aimed at correction of chronic disorders of duodenal patency.

Effects of emptying function of remaining stomach on QOL in postgastrectomy patients.

BACKGROUND: Attention has recently focused on decreased quality of life (QOL) that occurs in postgastrectomy patients. We verified how gastric emptying function affected QOL. METHODS: Subjects were 72 consecutive patients after gastrectomy for cancer, including 25 after distal gastrectomy (DG), 18 after proximal gastrectomy (PG), 16 after pylorus-preserving gastrectomy (PpG), and 13 after total gastrectomy (TG). Using the (13)C breath test method, (13)CO(2) levels in breath were measured over 2 h, and T (max) was determined. Questionnaires (Japanese versions of the Short-Form 36 [SF-36] and Gastrointestinal Symptom Rating Scale [GSRS]) were used to analyze QOL and correlations between questionnaire results and T (max). RESULTS: Mean T (max) (min) for each procedure was 15.4 for DG, 21.1 for PG, 41.3 for PpG, and 10.4 for TG. T (max) differed between procedures, but not between survey periods. SF-36 was not correlated with T (max), whereas GSRS showed a difference in diarrhea and total score between procedures, but not between survey periods. In addition, GSRS correlated with T (max) for abdominal pain, indigestion, and total score. The total scores showed a significant symptom aggregation in patients with T (max) less than 21 min. CONCLUSIONS: Gastrointestinal symptoms in postgastrectomy patients were associated with the function of the remaining stomach. The (13)C breath test is useful for objectively assessing such symptoms.

Postgastrectomy syndromes.

The first postgastrectomy syndrome was noted not long after the first gastrectomy was performed. The indications for gastric resection have changed dramatically over the past 4 decades, and the overall incidence of gastric resection has decreased. This article focuses on the small proportion of patients with severe, debilitating symptoms; these symptoms can challenge the acumen of the surgeon who is providing the patient's long-term follow-up and care. The article does not deal with the sequelae of bariatric surgery.

Analysis of esophageal reflux after proximal gastrectomy measured by wireless ambulatory 24-hr esophageal pH monitoring and TC-99m diisopropyliminodiacetic acid (DISIDA) scan.

BACKGROUND AND OBJECTIVES: Reflux is one of the most common sequela after proximal gastrectomy (PG). The aim of this study was to find a predicting factor related to the character of esophageal reflux after PG. METHODS: Wireless ambulatory 24-hr pH monitoring (for acid reflux, AR) and diisopropyliminodiacetic acid hepatobiliary scan (for bile reflux, BR) were performed on 24 patients who had reflux symptoms after PG with esophagogastrostomy from July 2008 to March 2009. Endoscopic examination was done and the length of remnant stomach (LoRS) was measure by postoperative UGI series. RESULTS: Eleven patients (45.8%) had only BR, 7 (29.2%) had AR only, Two patients (8.3%) had both acid and BR, and 3 (12.5%) had neither. The LoRS along greater curvature was significantly shorter in patients with only BR (16.11 +/- 2.87 cm) than in patients with only AR (23.69 +/- 6.15 cm, P = 0.003). Severity of symptoms or esophagitis was not significantly correlated with the content of acid or BR. CONCLUSION: Reflux symptom after PG is caused by either bile or acid rather than both. Character of reflux was related to the LoRS.

Results of completion gastrectomies in 44 patients with postsurgical gastric atony.

INTRODUCTION: Postsurgical gastric atony occurs infrequently after gastric surgery. However, the symptoms are disabling and refractory to medical management. The only effective treatment is completion gastrectomy. A few studies have examined in detail the long-term results of this radical procedure. METHODS: From 1988 through 2007, 44 patients (84% female, 16% male) underwent near-total or total completion gastrectomies for refractory postsurgical gastric atony. The average age was 52 (range 32-72). Gastric atony was documented using radionuclide solid food emptying studies. Charts were reviewed retrospectively to identify preoperative symptoms and long-term postoperative function, and the patients were contacted by phone to evaluate their current level of function. RESULTS: Of the original 44 patients, 66% (n = 29) were evaluated postoperatively at a mean of 5.6 + 4.5 years (range 0.5-15.0 years). Fourteen patients (32%) had died, and seven (16%) were lost to follow-up. Most common presenting symptoms were abdominal pain (98%), vomiting (98%), nausea (77%), diet limitation (75%), heartburn (64%), and weight loss (59%, average = 19% of BW). Postoperative complications occurred in 36% (n = 16), most commonly bowel obstruction (11%), anastomotic stricture (9%), and anastomotic leak (7%), and there was one perioperative death. At last follow-up, there were significant improvements in abdominal pain (97% to 59%, p < 0.001), vomiting (97% to 31%, p < 0.001), nausea (86% to 45%, p < 0.001), and diet limited to liquids or nothing at all (57% to 7%, p < 0.001). Some symptoms were more common postoperatively, including early satiety (24% to 89%, p < 0.001), and postprandial fullness (10% to 72%, p < 0.001). Average BMI at the time of surgery and at last follow-up were 23 and 21, respectively. Osteoporosis was diagnosed pre- and postoperatively in 17% and 67% of patients, respectively (p < 0.001). Seventy-eight percent of patients stated that they were in better health after surgery, while 17% were neutral, and 6% stated that they were worse off. Mean satisfaction with surgery was 4.7 (1-5 Likert scale). CONCLUSION: Completion gastrectomies in this patient population resulted in significant improvements in abdominal pain, vomiting, nausea, and severe diet limitations. Most patients, however, have significant ongoing gastrointestinal complaints, and the incidence of osteoporosis is high. Patient satisfaction is high; about 78% of patients believed their health status is improved. We believe these data support the selective use of completion gastrectomies in patients with severe postsurgical gastroparesis.
