Ultrasound-guided stellate ganglion block benefits the postoperative recovery of patients undergoing laparoscopic colorectal surgery: a single-center, double-blinded, randomized controlled clinical trial.

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.

Abdominal massage to prevent ileus after colorectal surgery. A single-center, prospective, randomized clinical trial: the MATRAC Trial.

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.

A randomized controlled study to assess the effect of mosapride citrate on intestinal recovery following gastrectomy.

The enhanced recovery after surgery (ERAS) protocol, including prokinetic medications, is commonly used to prevent postoperative ileus. Prospective studies evaluating the effectiveness of mosapride citrate, a prokinetic 5-hydroxytryptamine 4 receptor agonist, in patients undergoing gastrectomy within the ERAS framework are lacking. This double-blind randomized trial included patients who were scheduled for laparoscopic or robotic gastrectomy for gastric cancer. Participants were randomly assigned to either a control (placebo) or experimental (mosapride citrate) group, with drugs administered on postoperative days 1-5. Bowel motility was evaluated based on bowel transit time measured using radiopaque markers, first-flatus time, and amount of food intake. No significant differences were observed in baseline characteristics between the two groups. On postoperative day 3, no significant difference was observed in the number of radiopaque markers visible in the colon between the groups. All factors associated with bowel recovery, including the time of first flatus, length of hospital stay, amount of food intake, and severity of abdominal discomfort, were similar between the two groups. Mosapride citrate does not benefit the recovery of intestinal motility after minimally invasive gastrectomy in patients with gastric cancer. Therefore, routine postoperative use of mosapride citrate is not recommended in such patients.

The efficacy and safety of modified ultraearly oral hydration for alleviating thirst in patients after thoracoscopic surgery: a prospective randomized controlled trial.

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.

[Preliminary study on implementation of modified tubular gastric side-overlap anastomosis in laparoscopic proximal gastrectomy].

Objective: To investigate the feasibility and safety of implementing modified tubular gastric side-overlap anastomosis in laparoscopic proximal gastrectomy. Methods: In this retrospective, descriptive case series, we analyzed clinical data of seven patients who had undergone laparoscopic proximal gastrectomy and gastrointestinal reconstruction with modified tubular gastric side-overlap anastomosis from October 2022 to March 2023 in the Second Affiliated Hospital of Fujian Medical University. The study patients comprised five men and two women aged 57-72 years and of body mass index 18.5-25.7 kg/m2. All seven patients had preoperative gastroscopic and pathological evidence of esophagogastric junction cancer and all were found by preoperative enhanced computed tomography and/or endoscopic ultrasonography to have stage CT1-2N0M0 tumors. The main steps in the reconstruction of a modified tubular gastric side-overlap anastomosis are as follows: (1) mobilizing the lower esophagus and opening the left pleura to expand the space; (2) severing the esophagus with a linear cutter stapler; (3) creating a 3-cm-wide tubular stomach along the greater curvature; (4) creating a 5-cm guide line on the lesser curvature of the anterior wall of the tubular stomach and a small opening below the guide line; (5) rotating the esophageal stump 90° counterclockwise and making a small opening on the right posterior wall of the esophageal stump, along with using a 45-mm linear cutter stapler for esophagogastric side-to-side anastomosis under the guidance of the gastric tube and guide line ; (6) closing the common opening using barbed sutures; (7) embedding the cut edge of the esophageal stump such as to closely oppose it to the esophagus; (8) using barbed sutures to continuously suture the lower esophagus bilaterally to the anterior wall of the tubular stomach; and (9) closing the opened esophageal hiatus and pleura. The main outcome measures were intraoperative (operation time, digestive tract reconstruction time, closing the common opening time, intraoperative blood loss, and number of dissected lymph nodes), postoperative (time to passage of flatus , time to liquid diet, time to ambulation, length of postoperative hospital stay, and postoperative complications), pathological (maximum diameter of the tumor and pathological stage) and findings on follow-up. Results: Laparoscopic proximal gastrectomy with reconstruction of a modified tubular gastric side-overlap anastomosis was successfully completed in all seven patients; no conversion to laparotomy was required and there were no postoperative complications. The operation time, digestive tract reconstruction time, and closing of common opening time were 187-229, 61-79, and 7-9 minutes, respectively. Intraoperative blood loss was 15-23 ml and the number of dissected lymph nodes was 14-46 per case. Time to passage of flatus, time to liquid diet, time to ambulation, and postoperative hospital stay were 1-2, 2-3, 3-4, and 6-7 days, respectively. Postoperative pathological examination showed that the maximum tumor diameters were 1.6-3.3 cm in four patients with stage IA disease and three patients with stage IB. The seven patients were followed up for 6-11 months, during which none required routine use of proton pump inhibitors or gastric mucosal protective agents and there were no deaths or tumor recurrence/metastasis. No patients had anemia or hypoproteinemia 3 and 6 months after surgery. Six months after surgery, NRS2002 and GERDQ scores were 1-2 and 2-3, respectively. Gastroscopy showed narrow anastomoses in 6 patients with Los Angeles grade A and one patient with grade B disease. No evidence of significant bile reflux was found and no anastomotic stenosis or reflux was detected on upper gastrointestinal angiography. Conclusion: It is safe and feasible to implement modified tubular gastric side-overlap anastomosis for digestive tract reconstruction in laparoscopic proximal gastrectomy.

Washed microbiota transplantation improves symptoms and intestinal barrier function in patients with functional bowel disorders: a propensity-score matching analysis.

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.

Ashtangayoga for irritable bowel syndrome in a primary care setting: A feasibility study.

BACKGROUND: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by diarrhea or constipation and other symptoms such as pain, bloating, and flatulence. The disease often has a negative effect on quality of life and is also associated with symptoms of anxiety and depression. Pharmacological treatments are not always effective, and complementary and alternative treatments are common. METHODS: We conducted a study on a group intervention based on the Ashtanga school of yoga. Fourteen participants (three men, 11 women; average age 51.4, SD = 16) were recruited from primary care, and 10 completed treatment. At pre-measurement, 4 participants had severe, 9 moderate, and 1 mild IBS, according to the IBS-SSS scale. KEY RESULTS: The intervention was regarded as credible (CEQ M = 39.2 SD = 8.8), and no serious adverse events were reported. The intervention showed significant effects on all measurements at post, as follows: IBS-SSS PRE (M = 272.0 SD = 75.5); IBS-SSS POST (M = 177.0 SD = 103.5); GSRS-IBS PRE (M = 48.4 SD = 15.9); GSRS-IBS POST (M = 37.4 SD = 12.4); VSI PRE (M = 38.8 SD = 10.0) VSI POST (M = 25.9 SD = 10.1); PHQ12 PRE (M = 10.0 SD = 4.3); PHQ12 POST (M = 6.9 SD = 4.3); HADS anxiety PRE (M = 8.9 SD = 5.0) HADS anxiety POST (M = 5.7 SD = 3.3) HADS depression PRE (M = 5.6 SD = 3.2) HADS depression POST (M = 3.8 SD = 2.9) IBS-QOL PRE (M = 64.5 SD = 12.5) IBS-QOL POST (M = 72.3 SD = 10.0). The effects were maintained at follow-up, except for general anxiety and depression. Preliminary effects at 3-month follow-up were in the moderate to large range for main outcomes. CONCLUSION & INFERENCES: A 10-week group Ashtanga intervention was a feasible intervention for participants with IBS. Preliminary effects were promising and should be explored further in a randomized trial.

Comparison of postoperative ascites replacement strategies on time to first flatus after living donor liver transplantation: Albumin vs. lactated Ringer's solution.

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.

Timing of High-Dose-Rate Brachytherapy With External Beam Radiation Therapy in Patients With Intermediate- and High-Risk Localized Prostate Cancer and Its Effects on Toxicity and Quality of Life: A Randomized Controlled Trial (THEPCA).

PURPOSE: High-dose-rate brachytherapy (HDR-BT) and external beam radiation therapy (EBRT) are effective treatments for prostate cancer but cause genitourinary (GU) and gastrointestinal (GI) toxicities. There is no consensus on the timing of HDR-BT in relation to EBRT and the effect of sequencing on patients. The primary objective was to assess differences, if any, in the incidence of grade (G) 3 or higher GU toxicities from treatment. We also aimed to explore the incidence of G1 to G4 GI toxicities, quality of life (QOL), and patient satisfaction. Suppression of prostate-specific antigen (PSA) and signals for survival differences were also analyzed. METHODS AND MATERIALS: This was a single-center randomized trial in patients with intermediate- and high-risk localized prostate cancer who received HDR-BT before (Arm A) or after (Arm B) EBRT. Toxicities were graded using Common Terminology Criteria for Adverse Events (CTCAE). The International Prostate Symptom Score (IPSS) was used to assess lower urinary tract symptoms. The International Index of Erectile Function scale (IIEF) and Functional Assessment of Cancer Therapy-Prostate (FACT-P) were used to assess erectile dysfunction and QOL at 0, 3, 9, and 12 months. RESULTS: Fifty patients were recruited to each arm, with 48 and 46 patients completing treatment and follow-up in each arm, 81.5% of whom had high-risk disease. There were no G3 or G4 GU or GI toxicities. G1 urinary frequency was the most common adverse event experienced in both arms, peaking in incidence 3 months after treatment commenced (45.7% and 42.2% in Arm A and B, respectively). Up to 11% of patients reported G1 urinary frequency at 12 months. Other G1 GU toxicities experienced by >10% of patients were urinary tract obstruction, tract pain, and urgency. These symptoms also peaked in incidence at 3 months. G2 GU toxicities were uncommon and experienced in a maximum of 2 patients within each arm at any time point. Over 30% of patients had G1 flatulence at baseline, and this remained the most frequently occurring G1 GI toxicity throughout the study, peaking at 12 months (21.4% and 25.6% in Arm A and B, respectively). Other GI toxicities experienced by more than 10% of patients were GI pain, proctitis, and rectal mucositis, most of which demonstrated a peak incidence at 3 or 9 months. G2 GI toxicities were uncommon except for G2 flatulence. No significant difference was found in CTCAE, IPSS, IIEF, FACT-P, and QOL scores between the arms. Median prostate-specific antigen (PSA) follow-up was 5 years. Seven patients had treatment failure in each arm. Disease Free Survival (DFS) was 93.3% and 90.7% at 5 years in Arm A and B, respectively, with median failure time of 60 and 48 months in Arm A and B, respectively. There were no statistically significant differences between arms. CONCLUSIONS: The sequencing of HDR-BT and EBRT did not affect the incidence of G3 or G4 toxicities, and no significant differences were seen in other patient-reported outcomes. Treatment was well tolerated with maintained QOL scores. Treatment failure was low in both arms in a high-risk cohort; however, a larger study with longer follow-up is underway to establish whether the difference in median time to failure between the 2 arms is a signal of superiority.

Evaluating body mass index's impact on Da Vinci Robotic rectal cancer surgery, a retrospective study.

Robotic surgery addresses laparoscopic shortcomings and yields comparable results for low and high body mass index (BMI) patients. However, the impact of BMI on postoperative complications in robotic colorectal surgery remains debated. This study assessed the implications of BMI on short outcomes and postoperative complications, highlighting its unique role in the outcomes. Retrospective analysis of 119 patients who underwent robotic-assisted surgery for rectal cancer (January 2022 to March 2023). Patients grouped by BMI: normal weight (BMI < 23.9 kg/m2), overweight (BMI ≥ 23.9 kg/m2 and BMI < 27.9 kg/m2), and obese (BMI ≥ 27.9 kg/m2). Investigated BMI's impact on surgical outcomes and postoperative complications. Statistically significant differences (P < 0.05) in Clavien-Dindo, ASA scores. The obese group had a longer time to flatus (P = 0.002) and a higher re-operation rate than other groups (P = 0.01). The overweight group had a higher anastomotic fistula rate than the obese group. Overall complications showed no significant differences among BMI cohorts (P = 0.0295). There were no significant differences in TNM stages and comorbidities. BMI had no significant impact on overall postoperative complications in robotic surgery for rectal cancer. However, higher BMI correlated with a longer time to flatus and increased re-operation rate.

Efficacy of electroacupuncture in improving postoperative ileus in patients receiving colorectal surgery: a systematic review and meta-analysis.

BACKGROUND: This meta-analysis aimed to evaluate the efficacy and safety of electroacupuncture (EA) in improving postoperative ileus after colorectal surgery. METHODS: Electronic databases (e.g. Medline) were screened to identify randomized controlled trials that focused on the association between EA and postoperative ileus. Time to first flatus served as the primary outcome, while the secondary outcomes included time required for the recovery of other gastrointestinal functions (e.g. bowel sound recovery), time to tolerability of liquid/solid food, postoperative pain scores, risk of overall complications, and hospital length of stay. RESULTS: Our meta-analysis focusing on 16 studies with a total of 1562 patients demonstrated positive associations of EA with shorter times to the first flatus [mean difference (MD): -10.1 h, P <0.00001, n =1562], first defecation (MD: -11.77 h, P <0.00001, n =1231), bowel sound recovery (MD: -10.76 h, P <0.00001, n =670), tolerability of liquid (MD: -16.44 h, P =0.0002, n =243), and solid food (MD: -17.21 h, P =0.005, n =582) than those who received standard care. The use of EA was also correlated with a lower risk of overall complications (risk ratio:0.71, P =0.04, n =1011), shorter hospital length of stay (MD: -1.22 days, P =0.0001, n =988), and a lower pain score on postoperative days two (standardized MD: -0.87, P =0.009, n =665) and three (standardized MD: -0.45, P <0.00001, n =795), without a difference in time to first ambulation. CONCLUSION: Our findings showed an association between EA and enhanced gastrointestinal functional recovery and reduced pain severity following colorectal surgery, highlighting the potential benefits of incorporating EA into perioperative care to enhance recovery outcomes in this setting.

The Prevalence of Small Intestinal Bacterial Overgrowth After Roux-en-Y Gastric Bypass (RYGB): a Systematic Review and Meta-analysis.

We reviewed the literature on the prevalence of small intestinal bacterial overgrowth (SIBO) after Roux-en-Y gastric bypass (RYGB). Eight studies examining 893 patients were included. The mean age of the patients was 48.11 ± 4.89 years. The mean BMI before surgery and at the time of SIBO diagnosis was 44.57 ± 2.89 kg/m2 and 31.53 ± 2.29 kg/m2, respectively. Moreover, the results showed a 29% and 53% prevalence of SIBO at < 3-year and > 3-year follow-up after RYGB, respectively. Symptoms included abdominal pain, diarrhea, bloating, nausea, vomiting, constipation, soft stool, frequent defecation, flatulence, rumpling, dumping syndrome, and irritable bowel syndrome. SIBO is prevalent after RYGB; digestive symptoms should prompt the consideration of SIBO as a potential etiology. Antibiotic therapy has proven to be therapeutic.

Strategies to reduce ileus after colorectal surgery: A qualitative umbrella review of the collective evidence.

BACKGROUND: Various strategies were proposed to reduce postoperative ileus after colorectal surgery. This umbrella review aimed to provide a comprehensive overview of current evidence on measures to reduce the incidence and severity of postoperative ileus after colorectal surgery. METHODS: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic search was conducted in PubMed and Scopus to identify systematic reviews that assessed the efficacy of interventions used to prevent postoperative ileus after colorectal surgery. Data on study characteristics, interventions, and outcomes were summarized in a narrative manner. RESULTS: A total of 26 systematic reviews incorporating various strategies like early oral feeding, gum chewing, coffee consumption, medications, and acupuncture were included. Early oral feeding reduced postoperative ileus and accelerated bowel function return. The most assessed intervention was chewing gum, which was associated with a median reduction of postoperative ileus by 45% (range, 11%-59%) and shortening of the time to first flatus and time to defecation by a median of 11.9 and 17.7 hours, respectively. Coffee intake showed inconsistent results, with a median shortening of time to flatus and time to defecation by 1.32 and 14.45 hours, respectively. CONCLUSION: Early oral feeding, chewing gum, and alvimopan were the most commonly assessed and effective strategies for reducing postoperative ileus after colorectal surgery. Medications used to reduce postoperative ileus included alvimopan, intravenous lidocaine, dexamethasone, probiotics, and oral antibiotics. Intravenous dexamethasone and lidocaine and oral probiotics helped hasten bowel function return. Acupuncture positively impacted the recovery of bowel function.

Enhanced recovery after surgery (ERAS) in sacral tumour surgery and comprehensive description of a multidisciplinary program: a prospective study in a specialized hospital in China.

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.

Does Chewing Gum Lead to Earlier Postoperative Gastrointestinal Recovery in Children? A Systematic Review and Meta-analysis.

INTRODUCTION: Postoperative ileus is a common occurrence among children undergoing major operations, including gastrointestinal and spinal surgeries. Preliminary evidence in adults suggests that chewing gum plays a role in accelerating the return of postoperative gastrointestinal function. However, evidence is scarce in the paediatric population. The aim of this study was to investigate whether chewing gum has benefits for children. METHODS: We searched PubMed, Medline, Embase, and Cochrane Trials databases for randomised controlled trials that compare gum chewing with standard care after elective surgery in children from 1st Jan 2005 to 31st July 2021. We assessed the identified trials for quality and performed a systematic review and meta-analysis in accordance with PRISMA and registered in PROSPERO (CRD42022358801). The main outcome measures examined were time to flatus and stool postoperatively, time to tolerate oral intake, and length of hospital stay, which were analysed using fixed effects models. We also examined clinical complication rates and postoperative pain control. RESULTS: We included six eligible trials, with a total of 357 enrolled patients. The intervention was well tolerated without complications. There was no significant difference in time to flatus (-2.86 h; 95 % CI: -6.2 to 0.47 h, p = 0.09), time to stool (-6.39 h; 95 % CI: -13.9 to 1.2 h, p = 0.1), time to tolerate oral intake (-0.03 days; 95 % CI: -0.15 to 0.1 days, p = 0.68), and length of hospital stay (0.08 days; 95 % CI: -0.07 to 0.22 days, p = 0.29). Postoperative pain control (opioid consumption, pain score, nausea score) was similar in both groups (p > 0.05). CONCLUSION: Current evidence demonstrates that gum chewing is not associated with earlier postoperative gastrointestinal recovery in children. Future adequately powered and well-designed trials are necessary to evaluate any clinical benefit of chewing gum for children and whether it could result differences in healthcare satisfaction.

Safety and effectiveness of totally laparoscopic total gastrectomy vs laparoscopic-assisted total gastrectomy: a meta-analysis.

BACKGROUND: For gastric cancer with total gastrectomy, the usual laparoscopic surgical approaches are totally laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG). Due to its difficult anastomotic technique, the adoption of TLTG is limited. Therefore, surgeons prefer using LATG, which also led to TLTG being somewhat overlooked, so there is no clear conclusion today as to which surgical procedure is more favorable to the patient's recovery. This article aimed to compare the safety and short-term outcomes of the two surgical approaches. MATERIALS AND METHODS: Studies comparing TLTG and LATG, published up to December 2022, were searched in PubMed, Web of Science, and Embase databases. The study outcomes, including operative time, blood loss, anastomosis time, number of retrieved lymph nodes, proximal and distal resection margins, time to first fluid and soft diet, hospitalization duration, time to first flatus, and postsurgical and anastomotic complications, were compared between these two different surgical procedures. Statistics were analyzed with RevMan 5.4 and Stata 13.1. RESULTS: Fifteen publications were included in this study. The total sample included 3023 cases. The meta-analysis revealed no significant difference in overall postoperative complications between the two surgical approaches ( P >0.05). Compared with LATG, TLTG led to reduced intraoperative blood loss ( P <0.0001), an increased number of lymphatic node dissections ( P <0.0001), and decreased hospitalization duration ( P =0.002). However, operative time, anastomosis time, pulmonary infection, resection margins, time to first fluid and soft diet, time to first flatus and anastomosis-related complications were no significant difference between TLTG and LATG groups ( P >0.05). CONCLUSION: TLTG did not lead to an increase in overall postoperative complications, which is a reliable surgical approach for treatment of gastric cancer. Moreover, it may reduce harm to patients and enable them to obtain better surgical outcomes.

Transversus abdominis plane block improves postoperative recovery following cesarean delivery under general anesthesia: A propensity score matched retrospective cohort study.

OBJECTIVE: To evaluate the effects of transversus abdominis plane (TAP) block on postoperative recovery 24 h after cesarean delivery under general anesthesia. METHODS: A propensity-score-matched, retrospective cohort study was used. A total of 173 pregnancies resulting in elective cesarean delivery under general anesthesia between March 2021 and March 2022 were analyzed retrospectively. Patients receiving TAP block were compared with those receiving only intravenous analgesia. The Quality of Recovery 15 (QoR-15) score, assessed 24 h postoperatively using a 15-item questionnaire, was the primary outcome. Secondary outcomes included time to first ambulation, time to first flatus postoperatively, ability to tolerate ambulation, visual analog scale (VAS) score, hospitalization cost, and postoperative nausea and/or vomiting. RESULTS: The total QoR-15 score 24 h postoperatively in the TAP group was significantly higher than in the Control group (P < 0.001). Patients in the TAP group had higher Bruggemann comfort scale scores (P < 0.001), could better tolerate early postoperative ambulation (P < 0.001), and had shorter time to first ambulation (P < 0.001) and flatus (P < 0.001). Correlation analysis demonstrated an inverse relationship between the cumulative VAS pain scores, time to first postoperative ambulation, time to first flatus, and total QoR-15 score 24 h postoperatively. CONCLUSIONS: Following cesarean delivery under general anesthesia, TAP block combined with intravenous analgesia can improve postoperative recovery and shorten the time to postoperative ambulation and recovery of intestinal function.

Food intolerance related to gastrointestinal symptoms amongst adults living with bile acid diarrhoea: A cross-sectional study.

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.

Safety and efficacy of adding postbiotics in infant formula: a systematic review and meta-analysis.

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.

Effect of abdominal hot pack application on gastrointestinal motility recovery after comprehensive gynecologic staging surgery.

OBJECTIVE: To evaluate whether abdominal hot water pack application improves gastrointestinal motility following gynecological oncology surgery. METHODS: The study was registered at ClinicalTrials.gov (NCT04833699). (https://clinicaltrials.gov/ct2/show/NCT04833699?cond=NCT04833699&draw=2&rank=1). In this randomized controlled trial, participants were randomly assigned (1:1) to the hot water pack group (standardized enhanced recovery protocols plus rubber water bag with a fluffy cover filled with boiled tap water [80°C] and placed on the abdomen at 3, 6, 9, and 12 h postoperatively for 30 min each time) or the control group (standardized enhanced recovery protocols). A subumbilical or supraumbilical vertical midline incision was made to perform staging surgery procedures, including hysterectomy, salpingo-oophorectomy with retroperitoneal lymphadenectomy. The primary outcome was the time to first passage of flatus from the end of the staging procedure. RESULTS: In total, 121 women were randomized to the control (n = 62) or hot water pack (n = 59) group. The use of an abdominal hot water pack significantly reduced the mean time to passing first flatus (25.2 ± 3.6 vs. 30.6 ± 3.9 h; hazard ratio [HR] = 4.4; 95% confidence interval [CI]: 2.8-7.1; P < 0.0001), mean time to first bowel movements (28.4 ± 4.0 vs. 34.4 ± 4.5 h; HR = 4.9; 95% CI: 3.0-7.9; P < 0.0001), mean time to first defecation (33.4 ± 4.9 vs. 41.0 ± 7.6 h; HR = 4.3; 95% CI: 2.1-6.8; P < 0.0001), and mean time to tolerating solid diet (2.1 ± 0.6 vs. 2.8 ± 1.0 days; HR = 4.4; 95% CI: 2.2-8.7; P < 0.0001) compared to the control group. The postoperative ileus incidence was significantly lower in the hot water pack group (3.4%) than the control group (16.1%) (P = 0.01). CONCLUSION: Abdominal hot water pack application improved gastrointestinal function recovery in women following surgical staging procedures for gynecological malignancy.
