RESUMEN
DESCRIPTION: Belching, bloating, and abdominal distention are all highly prevalent gastrointestinal symptoms and account for some of the most common reasons for patient visits to outpatient gastroenterology practices. These symptoms are often debilitating, affecting patients' quality of life, and contributing to work absenteeism. Belching and bloating differ in their pathophysiology, diagnosis, and management, and there is limited evidence available for their various treatments. Therefore, the purpose of this American Gastroenterological Association (AGA) Clinical Practice Update is to provide best practice advice based on both controlled trials and observational data for clinicians covering clinical features, diagnostics, and management considerations that include dietary, gut-directed behavioral, and drug therapies. METHODS: This Expert Review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership, and underwent internal peer review by the Clinical Practice Updates Committee and external peer review through standard procedures of Gastroenterology. These best practice advice statements were drawn from a review of the published literature based on clinical trials, the more robust observational studies, and from expert opinion. Because systematic reviews were not performed, these best practice advice statements do not carry formal ratings regarding the quality of evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: Clinical history and physical examination findings and impedance pH monitoring can help to differentiate between gastric and supragastric belching. BEST PRACTICE ADVICE 2: Treatment options for supragastric belching may include brain-gut behavioral therapies, either separately or in combination, such as cognitive behavioral therapy, diaphragmatic breathing, speech therapy, and central neuromodulators. BEST PRACTICE ADVICE 3: Rome IV criteria should be used to diagnose primary abdominal bloating and distention. BEST PRACTICE ADVICE 4: Carbohydrate enzyme deficiencies may be ruled out with dietary restriction and/or breath testing. In a small subset of at-risk patients, small bowel aspiration and glucose- or lactulose-based hydrogen breath testing may be used to evaluate for small intestinal bacterial overgrowth. BEST PRACTICE ADVICE 5: Serologic testing may rule out celiac disease in patients with bloating and, if serologies are positive, a small bowel biopsy should be done to confirm the diagnosis. A gastroenterology dietitian should be part of the multidisciplinary approach to care for patients with celiac disease and nonceliac gluten sensitivity. BEST PRACTICE ADVICE 6: Abdominal imaging and upper endoscopy should be ordered in patients with alarm features, recent worsening symptoms, or an abnormal physical examination only. BEST PRACTICE ADVICE 7: Gastric emptying studies should not be ordered routinely for bloating and distention, but may be considered if nausea and vomiting are present. Whole gut motility and radiopaque transit studies should not be ordered unless other additional and treatment-refractory lower gastrointestinal symptoms exist to warrant testing for neuromyopathic disorders. BEST PRACTICE ADVICE 8: In patients with abdominal bloating and distention thought to be related to constipation or difficult evacuation, anorectal physiology testing is suggested to rule out a pelvic floor disorder. BEST PRACTICE ADVICE 9: When dietary modifications are needed (eg, low-fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet), a gastroenterology dietitian should preferably monitor treatment. BEST PRACTICE ADVICE 10: Probiotics should not be used to treat abdominal bloating and distention. BEST PRACTICE ADVICE 11: Biofeedback therapy may be effective for bloating and distention when a pelvic floor disorder is identified. BEST PRACTICE ADVICE 12: Central neuromodulators (eg, antidepressants) are used to treat bloating and abdominal distention by reducing visceral hypersensitivity, raising sensation threshold, and improving psychological comorbidities. BEST PRACTICE ADVICE 13: Medications used to treat constipation should be considered for treating bloating if constipation symptoms are present. BEST PRACTICE ADVICE 14: Psychological therapies, such as hypnotherapy, cognitive behavioral therapy, and other brain-gut behavior therapies may be used to treat patients with bloating and distention. BEST PRACTICE 15: Diaphragmatic breathing and central neuromodulators are used to treat abdominophrenic dyssynergia.

BACKGROUND & AIMS: Bloating is a common symptom in the general population and among disorders of gut-brain interaction, although its prevalence has not been well characterized. The aim of this study was to report the prevalence of bloating as a symptom in the worldwide population and to identify factors associated with this symptom in the general population. METHODS: Rome Foundation Global Epidemiology Study internet survey data were analyzed. After excluding respondents with potential organic causes of bowel symptoms, the current analysis included 51,425 individuals in 26 countries. Data included diet, medical history, quality of life, and Rome IV diagnostic questions. Presence of bloating was defined as experiencing bloating at least once per week for the last 3 months. Descriptive statistics estimated prevalence by country, region, and disorder of gut-brain interaction diagnosis. Logistic regression evaluated predictors of bloating. RESULTS: Nearly 18% of the global study population reported bloating (ranging from 11% in East Asia to 20% in Latin America). Prevalence decreased with age and women were approximately twice as likely as men to report bloating. More than one-half of respondents who reported weekly epigastric pain (71.39%), nausea (59.7%), or abdominal pain (61.69%) also reported bloating at least once per week. In logistic regression, the strongest associations were with abdominal pain (odds ratio, 2.90) and epigastric pain (odds ratio, 2.07). CONCLUSIONS: Bloating is common throughout the world. Nearly 18% of the general population experience bloating at least once per week. Reported bloating prevalence is lower in older age groups, most common in women, and strongly associated with abdominal pain.

Postbiotics, as emerging products, were added to infant formula, but their safety and efficacy are unclear. To clarify this issue, we wrote this meta-analysis. We searched PubMed, Embase, Web of Science and ProQuest from its establishment to February 2023. The review was registered on PROSPERO database (CRD42022352405). The effects of infant formula with and without postbiotics were compared, and the incidence of serious adverse events (SAEs), digestive symptoms, concentration of stool secretory immunoglobulin A (SIgA), and growth and development indexes were analyzed. Nine randomized controlled trials with 2065 participants were included. The addition of postbiotics to infant formula was found to increase the concentration of stool SIgA (P < 0.05) with very low certainty of evidence, without significantly impacting the incidence of SAEs, infantile colic, flatulence, diarrhea, vomiting, abdominal pain and gastrointestinal disorders, the daily weight gain, the total gain in body length and the daily head circumference gain (all P > 0.05). Adding postbiotics to the formula is safe for infants, which would not increase the incidence of SAEs, infantile colic, flatulence, diarrhea, vomiting, abdominal pain, and gastrointestinal disorders, and could increase the concentration of stool SIgA. IMPACT: Our study provides evidence that the addition of postbiotics to infant formula is safe but not effective. This is the first systematic review and meta-analysis of postbiotics. This study provides strong evidence for the safety of postbiotics and lays a foundation for related clinical trials.

INTRODUCTION: There is insufficient evidence regarding the optimal regimen for ascites replacement after living donor liver transplantation (LT) and its effectiveness. The aim of this study is to evaluate the impact of replacing postoperative ascites after LT with albumin on time to first flatus during recovery with early ambulation and incidence of acute kidney injury (AKI). METHODS: Adult patients who underwent elective living donor LT at Seoul National University Hospital from 2019 to 2021 were randomly assigned to either the albumin group or lactated Ringer's group, based on the ascites replacement regimen. Replacement of postoperative ascites was performed for all patients every 4 h after LT until the patient was transferred to the general ward. Seventy percent of ascites drained during the previous 4 h was replaced over the next 4 h with continuous infusion of fluids with a prescribed regimen according to the assigned group. In the albumin group, 30% of a total of 70% of drained ascites was replaced with 5% albumin solution, and remnant 40% was replaced with lactated Ringer's solution. In the lactated Ringer's group, 70% of drained ascites was replaced with only lactated Ringer's solution. The primary outcome was the time to first flatus from the end of the LT and the secondary outcome was the incidence of AKI for up to postoperative day 7. RESULTS: Among the 157 patients who were screened for eligibility, 72 patients were enrolled. The mean age was 63 ± 8.2 years, and 73.0 % (46/63) were male. Time to first flatus was similar between the two groups (66.7 ± 24.1 h vs. 68.5 ± 25.6 h, p = .778). The albumin group showed a higher glomerular filtration rate and lower incidence of AKI until postoperative day 7, compared to the lactated Ringer's group. CONCLUSIONS: Using lactated Ringer's solution alone for replacement of ascites after living donor LT did not reduce the time to first flatus and was associated with an increased risk of AKI. Further research on the optimal ascites replacement regimen and the target serum albumin level which should be corrected after LT is required.

BACKGROUND: Abdominal bloating is a common complaint in patients with functional and organic bowel disease. Rifaximin, a nonabsorbable antibiotic, has been tried for the treatment of this disease. We performed a systematic review and meta-analysis to study the efficacy of rifaximin in abdominal bloating and distension in patients with functional gastrointestinal disorders (FGID). METHODS: We accessed 4 databases (MEDLINE, Embase, SCOPUS, and Web of Science) to identify randomized placebo-controlled trials that utilized rifaximin in FGID. We excluded observational studies, those including patients with organic bowel disorders such as inflammatory bowel diseases, or those in which rifaximin was given for other indications, such as hepatic encephalopathy. RESULTS: A total of 1426 articles were available, of which 813 articles were screened after removing duplicates and 34 articles were selected for full-text review. Finally, 10 trials (3326 patients) were included. Rifaximin was administered in doses ranging from 400 to 1650 mg per day for 1 to 2 weeks. Rifaximin therapy led to a higher likelihood of improvement in symptoms of bloating (44.6% vs. 34.6%, RR 1.22, 95% CI 1.11, 1.35; n=2401 patients) without significant heterogeneity. However, daily doses less than 1200 mg/day were similar to placebo ( P =0.09). Bloating was quantified subjectively in 7 studies, and rifaximin led to a greater reduction in bloating scores compared with placebo (standardized mean difference -0.3, 95% CI -0.51, -0.1, P =0.04) but carried significant heterogeneity ( I2 =61.6%, P =0.01). CONCLUSIONS: Rifaximin therapy is associated with an increased likelihood of improvement in bloating and distension, as well as reduces the subjective severity of these symptoms in patients with FGID.

BACKGROUND: Disorders of gut-brain interaction (DGBI) cause a substantial health burden. Herein we studied the prevalence and characteristics of DGBI and symptoms of bloating/distension in El Paso, Texas on the US-Mexico border, providing a unique opportunity to study the effects of acculturation. METHODS: Subjects from community centers completed the Rome IV questionnaire for DGBI, short acculturation scale for Hispanics questionnaire, and bloating/distention Pictograms. Data were presented as prevalence (95% CI) and compared using χ 2 . RESULTS: Of 216 participants, 197 (127 Hispanics, 90 with English acculturation) were included and 177 completed the Pictograms. Fifty-one [25.9% (20 to 32.6)] subjects fulfilled the criteria for at least one DGBI. Globus and functional dyspepsia were the most common upper DGBI, each in [3.0% (1.1 to 6.5)]. Unspecified functional bowel disorders [8.6% (5.1 to 13.5)], followed by functional abdominal bloating/distention [8.1% (4.7 to 12.9], and irritable bowel syndrome [6.1% (3.2 to 10.4] were the most common functional bowel disorder. Ninety-one (51.4%) reported bloating and/or distension with Pictograms; more frequently in those with DGBI (80.9% vs 40.8%, P < 0.001). Bloating and/or distension were reported by Pictograms in 30% of those not reporting it in the Rome IV Questionnaire. There were no differences based on acculturation or in Hispanics versus non-Hispanics. CONCLUSIONS: On the US-Mexico border, we found a lower prevalence of DGBI than in the US or Mexico. Functional abdominal bloating/distention was more prevalent on the US-Mexico border than in either country. Bloating/distension was more commonly reported with Pictograms than with verbal descriptors. There were no differences between Hispanics and non-Hispanics, suggesting shared environmental/acquired including dietary factors as the underlying mechanisms.

BACKGROUND: Alterations in the intestinal microbiota may play a role in the pathogenesis of functional bowel disorders (FBDs). Probiotics are widely used to improve intestinal dysbacteriosis in FBDs. In the context of FBDs, washed microbiota transplantation (WMT) appear to be a promising therapeutic option. We aimed to compare probiotics with WMT by using a propensity-score matching analysis (PSMA). METHODS: We conducted a retrospective investigation of 103 patients with FBDs, including irritable bowel syndrome (IBS), functional constipation (FC), functional diarrhea (FDr), functional abdominal bloating (FAB). Patients were divided into the WMT group or probiotics group (taking probiotics capsules). Data on the following parameters were matched for PSMA: age; sex; disease course; body mass index; anxiety; insomnia; tobacco smoking; alcohol consumption; and levels of D-lactate, diamine oxidase, and lipopolysaccharide. Intestinal barrier function (IBF) and symptoms were evaluated both before and after treatment initiation. Prognostic factors were assessed by Cox proportional hazards regression analysis. RESULTS: PSMA identified in 34 matched pairs (11 IBS, 12 FC, 7 FDr, and 4 FAB in the probiotics group and 14 IBS, 13 FC, 5 FDr, and 2 FAB in the WMT group. Improvement of FBD symptoms was greater with WMT than probiotics (P = 0.002). The WMT group had significantly fewer patients with intestinal barrier damage than the probiotics group (38.2% vs. 67.6%, P = 0.041). This improvement of FBD with WMT was further reflected as a reduction in D-lactate levels (P = 0.031). Increased D-lactate levels which were identified as a prognostic factor for FBDs (HR = 0.248, 95%CI 0.093-0.666, P = 0.006) in multivariate Cox regression analysis. CONCLUSION: WMT could improve symptoms and IBF in patients with FBDs. Increased D-lactate levels in patients with FBDs may predict a favorable response to WMT treatment.

INTRODUCTION: Postoperative ileus (POI) is a significant complication following abdominal surgery, increasing morbidity and mortality. The cholinergic anti-inflammatory response is one of the major pathways involved in developing POI, but current recommendations to prevent POI do not target this. This review aims to summarise evidence for the use of acetylcholinesterase inhibitors, neostigmine and pyridostigmine, to reduce the time to return of gastrointestinal function (GI) following abdominal surgery. METHODS: A systematic search of various databases was performed from 1946 to May 2023. Randomised controlled trials (RCTs) on acetylcholinesterase inhibitors in intra-abdominal surgery were included. Data on time to flatus and/or stool and side effects were extracted. RESULTS: Among 776 screened manuscripts, 8 RCTs (703 patients) investigating acetylcholinesterase inhibitors in intra-abdominal surgery were analysed. Five studies showed a significant reduction in time to flatus and/or stool by 17-47.6 h. Methodological variations, differing procedure types, and potential bias were observed. Limited studies reported side effects or length of stay. CONCLUSION: Acetylcholinesterase inhibitors may reduce the time for GI to return. However, current evidence is limited and biased. Further studies incorporating acetylcholinesterase inhibitors in an enhanced recovery protocol are required to address this question, especially for patients undergoing colorectal surgery.

OBJECTIVE: Postoperative fasting following thoracoscopic surgery can cause intense thirst and oral discomfort. However, there is currently no research on ultraearly oral hydration (UEOH) in middle-aged or elderly patients after thoracoscopic surgery. The aim of this study was to investigate the effectiveness and safety of UEOH for improving oral discomfort after thoracoscopic surgery. METHODS: This single-center prospective double-blind randomized controlled trial was conducted from April 2022 to November 2023. A total of 64 middle-aged and elderly patients who underwent the first thoracoscopic surgery on the day were enrolled at our institution. Postoperatively, in the Postanesthesia Care Unit (PACU), patients were randomly assigned at a 1:1 ratio to either the UEOH group or the standard care (SC) group. The primary outcome was the patient's thirst score at 6 h after surgery. Secondary outcomes included the incidence of postoperative oral discomfort; pain scores; the occurrence of adverse reactions such as nausea, vomiting, regurgitation and aspiration; anxiety scores on the first postoperative day; the time to first flatus; and recovery satisfaction scores. RESULTS: The demographic and surgical characteristics were similar between the two groups. Patients in the UEOH group had lower thirst scores 6 h after surgery than did those in the SC group(16.1 ± 6.70 vs. 78.4 ± 8.42, P < 0.01). The incidence of postoperative oral discomfort (P < 0.01), anxiety scores on the first postoperative day (P<0.05), and time to first flatus (P<0.05) were better in the UEOH group. Additionally, the incidences of adverse reactions, such as postoperative nausea, vomiting, regurgitation and aspiration, were similar between the two groups (P>0.05). CONCLUSION: For middle-aged and elderly patients undergoing thoracoscopic surgery, the use of a modified UEOH protocol postoperatively can improve thirst and promote gastrointestinal recovery without increasing complications. TRIAL REGISTRATION: This single-center, prospective, RCT has completed the registration of the Chinese Clinical Trial Center at 07/12/2023 with the registration number ChiCTR2300078425.

BACKGROUND: With the increasing prevalence of colorectal cancer (CRC), optimizing perioperative management is of paramount importance. This study investigates the potential of stellate ganglion block (SGB), known for its stress response-mediating effects, in improving postoperative recovery. We postulate that preoperative SGB may enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery. METHODS: We conducted a randomized controlled trial of 57 patients undergoing laparoscopic colorectal cancer surgery at a single center. Patients, aged 18-70 years, were randomly assigned to receive either preoperative SGB or standard care. SGB group patients received 10 mL of 0.2% ropivacaine under ultrasound guidance prior to surgery. Primary outcome was time to flatus, with secondary outcomes encompassing time to defecation, lying in bed time, visual analog scale (VAS) pain score, hospital stays, patient costs, intraoperative and postoperative complications, and 3-year mortality. A per-protocol analysis was used. RESULTS: Twenty-nine patients in the SGB group and 28 patients in the control group were analyzed. The SGB group exhibited a significantly shorter time to flatus (mean [SD] hour, 20.52 [9.18] vs. 27.93 [11.69]; p = 0.012), accompanied by decreased plasma cortisol levels (mean [SD], postoperatively, 4.01 [3.42] vs 7.75 [3.13], p = 0.02). Notably, postoperative pain was effectively managed, evident by lower VAS scores at 6 h post-surgery in SGB-treated patients (mean [SD], 4.70 [0.91] vs 5.35 [1.32]; p = 0.040). Furthermore, patients in the SGB group experienced reduced hospital stay length (mean [SD], day, 6.61 [1.57] vs 8.72 [5.13], p = 0.042). CONCLUSIONS: Preoperative SGB emerges as a promising approach to enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery.

BACKGROUND: The role of food in managing bile acid diarrhoea (BAD) is poorly understood. The present study explored the prevalence of food intolerance amongst adults with BAD. METHODS: The study comprised a cross-sectional survey of adults with BAD determined by the 75 selenium homotaurocholic acid test (SeHCAT) living in the UK. Participants anonymously completed an online questionnaire on 39 food items. Frequency of food in general affecting BAD symptoms, as well as frequencies of diarrhoea, abdominal pain, bloating, flatulence and consequential food avoidance after food item ingestion, were assessed. Food group avoidance was also assessed. RESULTS: There were 434 participants who completed the questionnaire between April and May 2021 of whom 80% reported moderate to severe chronic diarrhoea. Food intolerances were reported by 88.0% (95% confidence interval [CI] = 84.6-90.9) of participants. Diarrhoea was reported most frequently after take-away food, fish and chips, creamy sauces, cream and large quantities of fruit (range 41.0%-33.6%). Lowest frequencies were for potato, avocado, mango, watermelon and pear (range 3.7%-7.4%) for the foods listed in the questionnaire. Similar trends were found for abdominal pain, bloating, flatulence and consequential food avoidance. Symptom-triggering within 30 min of ingestion was more prevalence than after 30 min for almost all foods. Food group avoidance was highest for fatty foods (81.2%; 95% CI = 77.8-85.3) followed by dairy (53.9%; 95% CI = 49.1-58.7). CONCLUSIONS: Perceived food intolerance amongst adults with BAD and persisting diarrhoeal symptoms is high. Important triggers were meals with a higher fat content and higher-fat dairy products. Diets amongst those with persisting diarrhoeal symptoms may be overly restrictive.

BACKGROUND: There is scarce literature on the effect of mechanical abdominal massage on the duration of ileus after colectomy, particularly in the era of enhanced recovery after surgery (ERAS). The aim of this study was to determine whether abdominal massage after colorectal surgery with anastomosis and no stoma helps toward a faster return of intestinal transit. METHODS: This study was a superiority trial and designed as a prospective open-label, single-center, randomized controlled clinical trial with two parallel groups. Patients scheduled to undergo intestinal resection and follow an ERAS protocol were randomly assigned to either the standard ERAS group or the ERAS plus massage group. The primary endpoint was the return of intestinal transit, defined as the first passage of flatus following the operation. Secondary endpoints included time of the first bowel motion, maximal pain, 30 day complications, complications due to massage, anxiety score given by the Hospital Anxiety and Depression (HAD) questionnaire, and quality of life assessed by the EQ-5D-3L questionnaire. RESULTS: Between July 2020 and June 2021, 36 patients were randomly assigned to the ERAS group or the ERAS plus massage group (n = 19). Patients characteristics were comparable. There was no significant difference in time to passage of the first flatus between the ERAS group and the ERAS plus abdominal massage group (1065 versus 1389 min, p = 0.274). No statistically significant intergroup difference was noted for the secondary endpoints. CONCLUSION: Our study, despite its limitations, failed to demonstrate any advantage of abdominal massage to prevent or even reduce symptoms of postoperative ileus after colorectal surgery. TRIAL REGISTRATION NUMBER: 38RC20.021.

Fructans are commonly used as dietary fibre supplements for their ability to promote the growth of beneficial gut microbes. However, fructan consumption has been associated with various dosage-dependent side effects. We characterised side effects in an exploratory analysis of a randomised trial in healthy adults (n = 40) who consumed 18 g/day inulin or placebo. We found that individuals weighing more or habitually consuming higher fibre exhibited the best tolerance. Furthermore, we identified associations between gut microbiome composition and host tolerance. Specifically, higher levels of Christensenellaceae R-7 group were associated with gastrointestinal discomfort, and a machine-learning-based approach successfully predicted high levels of flatulence, with [Ruminococcus] torques group and (Oscillospiraceae) UCG-002 sp. identified as key predictive taxa. These data reveal trends that can help guide personalised recommendations for initial inulin dosage. Our results support prior ecological findings indicating that fibre supplementation has the greatest impact on individuals whose baseline fibre intake is lowest.

PURPOSE: There were fewer data to guide the application of enhanced recovery after surgery (ERAS) theory into sacral tumour surgery. In the present study, we were aiming to describe a multidisciplinary program of ERAS and evaluate the availability in sacral tumour surgery. METHODS: This was a prospective study of patients with sacral tumour between March 2021 and September 2021 at a single centre. We proposed a multidisciplinary program of ERAS for pre-admission, preoperative, intraoperative, postoperative, and post-discharge clinical care which positively influenced outcomes of patients with sacral tumour. All patients were prospectively assigned into two groups, ERAS group in which patients received ERAS protocols (n = 63), No-ERAS group in which patients had conventional clinical pathways (n = 62). Patient data were collected which included demographics, preoperative preparation, detailed information of surgical procedure, 60-day reoperation rate, 60-day readmission, postoperative length of stay (PLOS), time to first ambulation and flatus after surgery, time to removal of last drainage tube, and visual analogue scale (VAS) score at first ambulation and discharge. Complications referred to ones that occurred within 60 days after surgery. The above parameters were compared between ERAS group and No-ERAS group. RESULTS: Time to first ambulation after surgery in ERAS group (mean 20.9 h) was significantly shorter than that in No-ERAS group (mean 104.3 ho). Meanwhile, time to first flatus after surgery in ERAS group (mean 26.7 h) was also significantly shorter than that in No-ERAS group (mean 37.3 h). Patients in ERAS group had statistically shorter PLOS (10.7 days) as compared to that in No-ERAS group (13.8 days). In ERAS group, 19 of 63 patients (30.2%) were discharged within seven days after surgery as compared to seven of 62 patients (11.3%) in No-ERAS group. VAS score at first ambulation in ERAS group was not obviously higher than that in No-ERAS group though the time of first ambulation in ERAS group was statistically earlier than one in No-ERAS group. Furthermore, VAS score at discharge in ERAS group was significantly lower than that in No-ERAS group. The rate of postoperative incision necrosis was 6.3% (4/63) in ERAS group and 8.1% (5/62) in No-ERAS group and all of these nine patients underwent reoperation before discharge. The difference was not statistically significant in the wound complication of incision necrosis and 60-day reoperation rate. Only one readmission occurred in No-ERAS group due to the surgical site infection and also there was no significant difference of 60-day readmission rate between these two groups. Furthermore, there was no statistical difference of complications of femoral artery thrombosis and rectal rupture between ERAS group and No-ERAS group. CONCLUSIONS: Our proposed ERAS pathway for sacral tumour surgery and early walking facilitate safe and prompt discharge. ERAS protocols of sacral tumour surgery could decrease PLOS without significantly increasing postoperative complications, 60-day readmission rate and 60-day reoperation rate. The application of ERAS pathway in the field of sacral tumour surgery should have personalized feature with regard to resection type.

BACKGROUND & AIMS: Although abdominal bloating is a common symptom, comparatively little is known about its prevalence in the community. This study aimed to examine the prevalence of bloating and assess related health care seeking using survey data from a nationally representative sample of nearly 89,000 Americans. METHODS: Participants completed the National Gastrointestinal (GI) Survey II to measure the presence and severity of GI symptoms including bloating. We assessed the prevalence of bloating in the past 7 days, as well as severity and health care seeking for bloating. Multivariable regression was performed to identify associations between the outcomes and covariates. RESULTS: Of 88,795 survey completers, 12,324 (13.9%) reported bloating in the past 7 days. Women and those with comorbidities (eg, irritable bowel syndrome, chronic constipation, ulcerative colitis) and concomitant GI symptoms (eg, abdominal pain, excess gas) had higher odds for bloating (all P < .001). These factors were also associated with more severe bloating (all P < .001). Among those who reported recent bloating, 58.5% never sought care for bloating-29% of whom were self-managing symptoms or were uncomfortable discussing symptoms with their providers. CONCLUSIONS: Bloating is common in the community because nearly 1 in 7 Americans have experienced this symptom in the past week. Women and those with certain comorbidities and concomitant GI symptoms are more likely to experience bloating and have more severe symptoms. Nearly one third of sufferers who have not sought care are managing symptoms on their own or are uncomfortable discussing it with their providers, emphasizing that efforts should be made to proactively inquire about bloating.

Chronic bloating and abdominal distension are common and highly bothersome gastrointestinal symptoms. Although the differential diagnoses for bloating and distension are broad, these symptoms are frequently associated with disorders of the gut-brain interaction. Functional abdominal bloating may be a result of visceral hypersensitivity, whereas abdominal distension seems to be a somatic behavioral response associated with abdominophrenic dyssynergia, featuring diaphragmatic contraction and abdominal wall relaxation. We review the available literature regarding abdominophrenic dyssynergia and comment on its epidemiology, diagnosis, treatment, and avenues to address in the near future.

BACKGROUND: This study aimed to systematically evaluate the effect of early oral feeding (EOF) versus late oral feeding (LOF) on postoperative complications and rehabilitation outcomes for patients with esophageal cancer. METHODS: This study searched relevant literature published up to March 2023 by computer retrieval of PubMed, Embase, The Cochrane Library, and Web of Science. A meta-analysis was performed using Review Manager 5.4 software to compare the effects of EOF and LOF on postoperative complications and recovery outcomes of patients with esophageal cancer. RESULTS: The study included 14 articles, including 9 retrospective studies, 4 randomized controlled trials (RCTs), and 1 prospective study. The 2555 patients included in the study comprised 1321 patients who received EOF and 1234 patients who received LOF. The results of the meta-analysis showed that compared with the LOF group, the EOF group has a shorter time to the first flatus postoperatively (mean difference [MD], - 1.12; 95% confidence interval [CI], (- 1.25 to - 1.00; P < 0.00001), a shorter time to the first defecation postoperatively (MD, - 1.31; 95% CI, - 1.67 to - 0.95;, P < 0.00001], and a shorter hospital stay postoperatively (MD, - 2.87; 95% CI, - 3.84 to - 1.90; P < 0.00001). The two groups did not differ significantly statistically in terms of postoperative anastomotic leakage rate (P = 0.10), postoperative chyle leakage rate (P = 0.10), or postoperative pneumonia rate (P = 0.15). CONCLUSION: Early oral feeding after esophageal cancer surgery can shorten the time to the first flatus and the first defecation postoperatively, shorten the hospital stay, and promote the recovery of patients. Moreover, it has no significant effect on the incidence of postoperative complications.

BACKGROUND: This study aimed to investigate the feasibility of early oral feeding (EOF) after neoadjuvant chemotherapy (nCT) combined with "non-tube no fasting"-enhanced recovery after minimally invasive esophagectomy (MIE). METHODS: This retrospective study investigated patients who underwent nCT combined with non-tube no fasting-enhanced recovery after MIE in the Department of Thoracic Surgery, Ward I, of the authors' hospital from January 2014 to August 2017. These patients were divided into an early oral feeding (EOF) group (n = 112) and a late oral feeding (LOF) group (n = 69). The postoperative complications were compared between the two groups. RESULTS: The study enrolled 181 patients (112 patients in the EOF group and 69 patients in the LOF group). No significant differences were found between the two groups in the incidence rates of complications such as anastomotic leakage (P = 0.961), pneumonia (P = 0.450), respiratory failure (P = 0.944), heart failure (P = 1.000), acute respiratory distress syndrome (ARDS) (P = 0.856), and unplanned reoperation (P = 0.440), whereas the time to the first postoperative flatus/bowel movement (P < 0.001) and the postoperative length of stay (P < 0.001) were significantly better in the EOF group than in the LOF group.. CONCLUSIONS: In this study, EOF after nCT combined with non-tube no fasting-enhanced recovery after MIE did not significantly increase complications, but significantly shortened the time to the first postoperative flatus/bowel movement and the postoperative length of stay.

BACKGROUND: Surgeon-administered transversus abdominis plane block is a contemporary approach to providing postoperative analgesia, and this approach is performed by transperitoneally administering local anesthetic in the plane between the internal oblique and transversus abdominis muscles to target the sensory nerves of the anterolateral abdominal wall. Although this technique is used in many centers, it has not been studied prospectively in patients undergoing a midline laparotomy. OBJECTIVE: This study aimed to evaluate whether surgeon-administered transversus abdominis plane block reduces postoperative opioid requirements and improves clinical outcomes. STUDY DESIGN: In this double-blind, randomized, placebo-controlled trial, patients with a suspected or proven gynecologic malignancy undergoing surgery through a midline laparotomy at 1 Canadian tertiary academic center were randomized to either the bupivacaine group (surgeon-administered transversus abdominis plane blocks with 40 mL of 0.25% bupivacaine) or the placebo group (surgeon-administered transversus abdominis plane blocks with 40 mL of normal saline solution) before fascial closure. The primary outcome was the total dose of opioids (in morphine milligram equivalents) received in the first 24 hours after surgery. The secondary outcomes included opioid doses between 24 and 48 hours, pain scores, postoperative nausea and vomiting, incidence of clinical ileus, time to flatus, and hospital length of stay. The exclusion criteria included contraindications to study medication, history of chronic opioid use, significant adhesions on the anterior abdominal wall preventing access to the injection site, concurrent nonabdominal surgical procedure, and the planned use of neuraxial anesthesia or analgesia. To detect a 20% decrease in opioid requirements with a 2-sided type 1 error of 5% and power of 80%, a sample size of 36 patients per group was calculated. RESULTS: From October 2020 to November 2021, 38 patients were randomized to the bupivacaine arm, and 41 patients were randomized to the placebo arm. The mean age was 60 years, and the mean body mass index was 29.3. A supraumbilical incision was used in 30 of 79 cases (38.0%), and bowel resection was performed in 10 of 79 cases (12.7%). Patient and surgical characteristics were evenly distributed. The patients in the bupivacaine group required 98.0±59.2 morphine milligram equivalents in the first 24 hours after surgery, whereas the patients in the placebo group required 100.8±44.0 morphine milligram equivalents (P=.85). The mean pain score at 4 hours after surgery was 3.1±2.4 (0-10 scale) in the intervention group vs 3.1±2.0 in the placebo group (P=.93). Clinically significant nausea or vomiting was reported in 1 of 38 patients (2.6%) in the intervention group vs 1 of 41 patients (2.4%) in the placebo group (P=.95). Time to first flatus, rates of clinical ileus, and length of stay were similar between groups. Subgroup analysis of patients with a body mass index of <25 and patients who received an infraumbilical incision showed similarly comparable outcomes. CONCLUSION: Surgeon-administered transversus abdominis plane block with bupivacaine was not found to be superior to the placebo intervention in reducing postoperative opioid requirements or improving other postoperative outcomes for patients undergoing a midline laparotomy. These results differed from previous reports evaluating the ultrasound-guided transversus abdominis plane block approach. Surgeon-administered transversus abdominis plane block should not be considered standard of care in postoperative multimodal analgesia.

BACKGROUND: The effect of anterograde lavage in patients with rectal cancer who underwent anterior resection and plan to receive stoma closure is unclear. OBJECTIVE: This study aimed to investigate the effect of anterograde lavage on postoperative bowel function recovery in patients who underwent temporary loop ileostomy and stoma closure. DESIGN: This was a hospital-based retrospective cohort study. SETTINGS: This study was conducted at a tertiary referral center. PATIENTS: All consecutive patients who underwent anterior resection for rectal cancer and were planning to receive stoma closure from March through December 2019 were included. INTERVENTIONS: The enrolled patients were divided into 2 groups according to whether they received anterograde lavage before stoma closure. MAIN OUTCOME MEASURES: Short-term functional outcomes, including time to first passing of flatus, first defecation time, and recovery time to first meal, were compared between the groups. Secondary outcomes included length of hospital stay, total cost of hospitalization, and postoperative complications. RESULTS: A total of 222 eligible participants were included in the analysis, including 114 in the lavage group and 108 in the nonlavage group. No statistically significant differences were found in age, sex ratio, or distance between the anastomotic line and dentate line. In the lavage group, patients' time to first passing of flatus (38 vs 42 h; p = 0.006), first defecation time (42 vs 48 h; p < 0.001), recovery time to first meal (48 vs 55.5 h; p < 0.001), and length of hospital stay (5 vs 7 d; p < 0.001) were significantly shorter than those in the nonlavage group, and the total cost of hospitalization was significantly lower than that of the nonlavage group (25,000 vs 28,000 RMB; p < 0.001). No significant difference was found in the incidence of postoperative complications between the 2 groups (p = 0.067). LIMITATIONS: This study is limited by its relatively small sample size and retrospective design with single-center participants. CONCLUSIONS: Anterograde lavage before stoma closure is safe and noninvasive. For patients receiving anterior resection and planning to have stoma closure, this procedure can potentially help recover bowel function more rapidly.

EFECTO DEL LAVADO ANTERGRADO MEDIANTE ILEOSTOMA TEMPORAL EN ASA SOBRE LA RECUPERACIN DE LA FUNCIN INTESTINAL EN PACIENTES QUE RECIBEN CIERRE DE ESTOMA UN ESTUDIO DE COHORTE RETROSPECTIVO: ANTECEDENTES:No está claro el efecto del lavado anterógrado en pacientes con cáncer de recto con resección anterior que planean recibir el cierre del estoma.OBJETIVO:Investigar el efecto del lavado anterógrado en la recuperación de la función intestinal posoperatoria en pacientes que se sometieron a ileostomía en asa temporal y cierre de estoma.DISEÑO:Estudio de cohorte retrospectivo basado en el hospital.AJUSTES:Centro de referencia terciario.PACIENTES:Todos los pacientes que se sometieron a una resección anterior por cáncer de recto y que planeaban recibir el cierre del estoma desde marzo hasta diciembre de 2019.INTERVENCIONES:Los pacientes inscritos se dividieron en dos grupos según si recibieron lavado anterógrado antes del cierre del estoma.PRINCIPALES MEDIDAS DE RESULTADO:Los resultados funcionales a corto plazo, incluido el tiempo de la primera evacuación de flatos, tiempo de la primera defecación y tiempo de recuperación hasta la primera comida, se compararon entre los grupos. Resultados secundarios incluyeron duración de la estancia hospitalaria, costo total de la hospitalización y complicaciones posoperatorias.RESULTADOS:Se incluyeron en el análisis un total de 222 participantes elegibles, incluidos 114 en el grupo de lavado y 108 en el grupo de no lavado. No hubo diferencias estadísticamente significativas en la edad, la proporción de sexos o la distancia entre la línea de anastomosis y la línea dentada. En el grupo de lavado, el tiempo de la primera evacuación de flatos de los pacientes (38 vs 42 h; p = 0,006), el tiempo de la primera defecación (42 vs 48 h; p < 0,001), el tiempo de recuperación hasta la primera comida (48 vs 55,5 h; p < 0,001) y la duración de la estancia hospitalaria (5 vs 7 días; p < 0,001) fueron significativamente más cortos que los del grupo de no lavado, y el costo total de la hospitalización fue significativamente menor que el del grupo de no lavado (25000 vs 28000 RMB; p < 0,001). No hubo diferencia significativa en la incidencia de complicaciones postoperatorias entre los dos grupos (p = 0,067).LIMITACIONES:Este estudio está limitado por su tamaño de muestra relativamente pequeño y su diseño retrospectivo con participantes de un solo centro.CONCLUSIONES:El lavado anterógrado antes del cierre del estoma es seguro y no invasivo. Para los pacientes que se someten a una resección anterior y planean cerrar el estoma, este procedimiento puede ayudar potencialmente a recuperar la función intestinal más rápidamente.
