Preoperative nutrition therapy in people undergoing gastrointestinal surgery.

BACKGROUND: Poor preoperative nutritional status has been consistently linked to an increase in postoperative complications and worse surgical outcomes. We updated a review first published in 2012. OBJECTIVES: To assess the effects of preoperative nutritional therapy compared to usual care in people undergoing gastrointestinal surgery. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, three other databases and two trial registries on 28 March 2023. We searched reference lists of included studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of people undergoing gastrointestinal surgery and receiving preoperative nutritional therapy, including parenteral nutrition, enteral nutrition or oral nutrition supplements, compared to usual care. We only included nutritional therapy that contained macronutrients (protein, carbohydrate and fat) and micronutrients, and excluded studies that evaluated single nutrients. We included studies regardless of the nutritional status of participants, that is, well-nourished participants, participants at risk of malnutrition, or mixed populations. We excluded studies in people undergoing pancreatic and liver surgery. Our primary outcomes were non-infectious complications, infectious complications and length of hospital stay. Our secondary outcomes were nutritional aspects, quality of life, change in macronutrient intake, biochemical parameters, 30-day perioperative mortality and adverse effects. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodology. We assessed risk of bias using the RoB 1 tool and applied the GRADE criteria to assess the certainty of evidence. MAIN RESULTS: We included 16 RCTs reporting 19 comparisons (2164 participants). Seven studies were new for this update. Participants' ages ranged from 21 to 79 years, and 62% were men. Three RCTs used parenteral nutrition, two used enteral nutrition, eight used immune-enhancing nutrition and six used standard oral nutrition supplements. All studies included mixed groups of well-nourished and malnourished participants; they used different methods to identify malnutrition and reported this in different ways. Not all the included studies were conducted within an Enhanced Recovery After Surgery (ERAS) programme, which is now current clinical practice in most hospitals undertaking GI surgery. We were concerned about risk of bias in all the studies and 14 studies were at high risk of bias due to lack of blinding. We are uncertain if parenteral nutrition has any effect on the number of participants who had a non-infectious complication (risk ratio (RR) 0.61, 95% confidence interval (CI) 0.36 to 1.02; 3 RCTs, 260 participants; very low-certainty evidence); infectious complication (RR 0.98, 95% CI 0.53 to 1.80; 3 RCTs, 260 participants; very low-certainty evidence) or length of hospital stay (mean difference (MD) 5.49 days, 95% CI 0.02 to 10.96; 2 RCTs, 135 participants; very low-certainty evidence). None of the enteral nutrition studies reported non-infectious complications as an outcome. The evidence is very uncertain about the effect of enteral nutrition on the number of participants with infectious complications after surgery (RR 0.90, 95% CI 0.59 to 1.38; 2 RCTs, 126 participants; very low-certainty evidence) or length of hospital stay (MD 5.10 days, 95% CI -1.03 to 11.23; 2 RCTs, 126 participants; very low-certainty evidence). Immune-enhancing nutrition compared to controls may result in little to no effect on the number of participants experiencing a non-infectious complication (RR 0.79, 95% CI 0.62 to 1.00; 8 RCTs, 1020 participants; low-certainty evidence), infectious complications (RR 0.74, 95% CI 0.53 to 1.04; 7 RCTs, 925 participants; low-certainty evidence) or length of hospital stay (MD -1.22 days, 95% CI -2.80 to 0.35; 6 RCTs, 688 participants; low-certainty evidence). Standard oral nutrition supplements may result in little to no effect on number of participants with a non-infectious complication (RR 0.90, 95% CI 0.67 to 1.20; 5 RCTs, 473 participants; low-certainty evidence) or the length of hospital stay (MD -0.65 days, 95% CI -2.33 to 1.03; 3 RCTs, 299 participants; low-certainty evidence). The evidence is very uncertain about the effect of oral nutrition supplements on the number of participants with an infectious complication (RR 0.88, 95% CI 0.60 to 1.27; 5 RCTs, 473 participants; very low-certainty evidence). Sensitivity analysis based on malnourished and weight-losing participants found oral nutrition supplements may result in a slight reduction in infections (RR 0.58, 95% CI 0.40 to 0.85; 2 RCTs, 184 participants). Studies reported some secondary outcomes, but not consistently. Complications associated with central venous catheters occurred in RCTs involving parenteral nutrition. Adverse events in the enteral nutrition, immune-enhancing nutrition and standard oral nutrition supplements RCTs included nausea, vomiting, diarrhoea and abdominal pain. AUTHORS' CONCLUSIONS: We were unable to determine if parenteral nutrition, enteral nutrition, immune-enhancing nutrition or standard oral nutrition supplements have any effect on the clinical outcomes due to very low-certainty evidence. There is some evidence that standard oral nutrition supplements may have no effect on complications. Sensitivity analysis showed standard oral nutrition supplements probably reduced infections in weight-losing or malnourished participants. Further high-quality multicentre research considering the ERAS programme is required and further research in low- and middle-income countries is needed.

Prevention of Postoperative Malnutrition with Oral Nutritional Supplements in Patients Undergoing Gastrointestinal Surgery.

Oral nutritional supplements (ONSs) offer support for the nutritional needs of surgical patients. However, their efficacy is contingent upon the nutrient composition, absorption efficiency, and postingestion tolerance. Our study included a cohort of 84 patients who underwent elective open surgery involving at least one intestine anastomosis. To mitigate the risk of malnutrition, 2 groups of 28 patients each received either a high-protein low-osmotic ONS (Group I) or a high-calorie high-osmotic ONS (Group II). A standard diet was used in the control group (Group III). The metabolic effects were evaluated by measuring body weight and relative change in body weight (Δkg) from 24 h (-1 day) presurgery to 28 days postprocedure. Subjective tolerance following ONS consumption on the second postoperative day was also assessed. Our findings showed that, across all groups, the average body weight decreased during the initial 2 weeks postsurgery, subsequently stabilizing or returning to baseline levels by the third and fourth week of observation. Patients receiving ONS demonstrated greater weight gain between days 14 and 28, with Group I exhibiting the highest rate of gain. Low-osmotic ONS displayed superior tolerance and elicited fewer patient complaints postconsumption. Postoperative hospitalization duration did not differ significantly among the nutritional strategies. In conclusion, early administration of ONS supplies essential nutrients and facilitates refeeding, thereby reducing the risk of malnutrition. Low-osmotic preparations are better tolerated and contribute more effectively to the restoration of preoperative body weight, despite their lower caloric content.

Probiotics for the postoperative management of term neonates after gastrointestinal surgery.

BACKGROUND: The intestinal microflora has an essential role in providing a barrier against colonisation of pathogens, facilitating important metabolic functions, stimulating the development of the immune system, and maintaining intestinal motility. Probiotics are live microorganisms that can be administered to supplement the gut flora. Neonates who have undergone gastrointestinal surgery are particularly susceptible to infectious complications in the postoperative period. This may be partly due to a disruption of the integrity of the gut and its intestinal microflora. There may be a role for probiotics in reducing the incidence of sepsis and improving intestinal motility, thus reducing morbidity and mortality and improving enteral feeding in neonates in the postoperative period. OBJECTIVES: To evaluate the efficacy and safety of administering probiotics after gastrointestinal surgery for the postoperative management of neonates born from 35 weeks of gestation. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and trial registries in August 2023. We checked reference lists of included studies and relevant systematic reviews for additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that investigated the postoperative administration of oral probiotics versus placebo or no treatment in neonates born from 35 weeks of gestation who had one or more gastrointestinal surgical procedures. We applied no restrictions regarding the type or dosage of probiotics or the duration of treatment. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods, and we used GRADE to assess the certainty of evidence. MAIN RESULTS: We identified one RCT that recruited 61 neonates with a gestational age of 35 weeks or more. All infants were admitted to a neonatal intensive care unit and had surgery for gastrointestinal pathologies. There may be little or no difference in proven sepsis (positive bacterial culture, local or systemic) between infants who receive probiotics compared with those who receive placebo (odds ratio (OR) 0.64, 95% confidence interval (CI) 0.16 to 2.55; 61 infants; low-certainty evidence). Probiotics compared to placebo may have little or no effect on time to full enteral feeds (mean difference (MD) 0.63 days, 95% CI -4.02 to 5.28; 61 infants; low-certainty evidence). There were no reported deaths prior to discharge from hospital in either study arm. Two weeks after supplementation, the infants who received probiotics had a substantially higher relative abundance of non-pathogenic intestinal microflora (Bifidobacteriaceae) than those who received placebo (MD 38.22, 95% CI 28.40 to 48.04; 39 infants; low-certainty evidence). AUTHORS' CONCLUSIONS: This review provides low-certainty evidence from one small RCT that probiotics compared to placebo have little or no effect on the risk of proven sepsis (positive bacterial culture, local or systemic) or time to full-enteral feeds in neonates who have undergone gastrointestinal surgery. Probiotics may substantially increase the abundance of beneficial bacterial in the intestine of these neonates, but the clinical implications of this finding are unknown. There is a need for adequately powered RCTs to assess the role of probiotics in this population. We identified two ongoing studies. As neither reported the gestational age of prospective study participants, we are unsure if they will be eligible for inclusion in this review.

[Transanal Tumor Resection: Indication, Surgical Technique and Management of Complications]. / Transanale Tumorresektion: Indikation, Operationstechniken und Komplikationsmanagement.

Transanal resection procedures are special operations for the minimally invasive treatment of rectal tumours. Apart from benign tumours, this procedure is suitable for the excision of low-risk T1 rectal carcinomas, if these can be completely removed (R0 resection). With stringent patient selection, very good oncological results are achieved. Various international trials are currently evaluating whether local resection procedures are oncologically sufficient if there is a complete or near complete response after neoadjuvant radio-/chemotherapy. Numerous studies have shown that the functional results and the postoperative quality of life after local resection are excellent, especially considering the well-known functional deficits of alternative operations, such as low anterior or abdominoperineal resection.Severe complications are very rare. Most complications, such as urinary retention or subfebrile temperatures, are minor in nature. Suture line dehiscences are usually clinically unremarkable. Major complications comprise significant haemorrhage and the opening of the peritoneal cavity. The latter must be recognized intraoperatively and can usually be managed by primary suture. Infection, abscess formation, rectovaginal fistula, injury of the prostate or even urethra are extremely rare complications.

The effect of post-discharge oral nutritional supplements on outcomes after gastrointestinal surgery: A systematic review and meta-analysis.

BACKGROUND: Malnutrition is a risk-factor for adverse postoperative outcomes. This systematic review and meta-analysis evaluated the impact of post-discharge oral nutritional supplements (ONS) on outcomes in patients undergoing gastrointestinal surgery. METHODS: The Medline and Embase databases were searched for randomised clinical trials in patients undergoing gastrointestinal surgery who had received ONS for at least two weeks after discharge from hospital. The primary endpoint was weight change. Secondary endpoints included quality of life, total lymphocyte count, total serum protein and serum albumin. Analysis was performed using RevMan5.4 software. RESULTS: Fourteen studies with 2480 participants (1249 ONS/1231 controls) were included. Pooling of results revealed that a reduction in postoperative weight loss in patients taking ONS, when compared with control: overall weighted mean difference (WMD) -1.69 kg, 95% CI -2.98 to -0.41, P = 0.01. Serum albumin concentration was increased in the ONS group: WMD = 1.06 g/L, 95% CI 0.04 to 2.07, P = 0.04. Haemoglobin was also increased: WMD = 2.91 g/L, 95% CI 0.58 to 5.25, P = 0.01. Total serum protein, total lymphocyte count, total cholesterol and quality of life did not differ between the groups. Patient compliance was relatively poor across the studies and there was variability in the composition of ONS, volume consumed and surgical procedures performed. CONCLUSIONS: There was a reduction in postoperative weight loss and an improvement in some biochemical parameters in patients receiving ONS after gastrointestinal surgery. Future RCTs with more consistent methodologies are needed to investigate the efficacy of ONS after discharge from hospital following gastrointestinal surgery.

Efficacy and safety of salvianolate and enoxaparin in the prevention of perioperative deep venous thrombosis in gastrointestinal surgery.

OBJECTIVE: In this study, the efficacy and safety of salvianolate were compared with enoxaparin in the prevention of perioperative deep vein thrombosis in gastrointestinal surgery. METHODS: From October 2017 to September 2019, 563 patients who underwent gastrointestinal surgery were collected. Based on the inclusion and exclusion criteria, 119 patients were divided into two groups: enoxaparin group (n = 65) and salvianolate group (n = 54). Comparisons were made regarding the outcomes: prothrombin time (PT), prothrombin activity (PTA), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (FIB), thrombin time (TT), D-dimer level (D-D), platelet count (PLT), hematokrit (HCT), and incidence of deep vein thrombosis (DVT). RESULTS: The main outcomes showed no significance between enoxaparin group and salvianolate group (p > .05). The incidence of DVT in salvianolate group was 1.85%, significantly lower than that in enoxaparin group (12.3%) (p < .05). No serious adverse reactions occurred in the two groups during treatment. CONCLUSION: Compared with enoxaparin, salvianolate has an advantage in the prevention of perioperative thrombosis in gastrointestinal surgery with a lower incidence of DVT.

The impact of preoperative oral nutrition supplementation on outcomes in patients undergoing gastrointestinal surgery for cancer in low- and middle-income countries: a systematic review and meta-analysis.

Malnutrition is an independent predictor for postoperative complications in low- and middle-income countries (LMICs). We systematically reviewed evidence on the impact of preoperative oral nutrition supplementation (ONS) on patients undergoing gastrointestinal cancer surgery in LMICs. We searched EMBASE, Cochrane Library, Web of Science, Scopus, WHO Global Index Medicus, SciELO, Latin American and Caribbean Health Sciences Literature (LILACS) databases from inception to March 21, 2022 for randomised controlled trials evaluating preoperative ONS in gastrointestinal cancer within LMICs. We evaluated the impact of ONS on all postoperative outcomes using random-effects meta-analysis. Seven studies reported on 891 patients (446 ONS group, 445 control group) undergoing surgery for gastrointestinal cancer. Preoperative ONS reduced all cause postoperative surgical complications (risk ratio (RR) 0.53, 95% CI 0.46-0.60, P < 0.001, I2 = 0%, n = 891), infection (0.52, 0.40-0.67, P = 0.008, I2 = 0%, n = 570) and all-cause mortality (0.35, 0.26-0.47, P = 0.014, I2 = 0%, n = 588). Despite heterogeneous populations and baseline rates, absolute risk ratio (ARR) was reduced for all cause (pooled effect -0.14, -0.22 to -0.06, P = 0.006; number needed to treat (NNT) 7) and infectious complications (-0.13, -0.22 to -0.06, P < 0.001; NNT 8). Preoperative nutrition in patients undergoing gastrointestinal cancer surgery in LMICs demonstrated consistently strong and robust treatment effects across measured outcomes. However additional higher quality research, with particular focus within African populations, are urgently required.

Effectiveness and safety of acupuncture for postoperative ileus following gastrointestinal surgery: A systematic review and meta-analysis.

BACKGROUND: Postoperative ileus (POI) is an important complication of gastrointestinal (GI) surgery. Acupuncture has been increasingly used in treating POI. This study aimed to assess the effectiveness and safety of acupuncture for POI following GI surgery. METHODS: Seven databases (PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Wan fang Data, VIP Database for Chinese Technical Periodicals, and Chinese Biomedical Literature Database) and related resources were searched from inception to May 30, 2021. Randomized controlled trials (RCTs) reporting the acupuncture for POI in GI were included. The quality of RCTs was assessed by the Cochrane Collaboration Risk of Bias tool, and the certainty of the evidence was evaluated by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. A meta-analysis was performed by using RevMan 5.4 software. RESULTS: Eighteen RCTs involving 1413 participants were included. The meta-analysis showed that acupuncture could reduce the time to first flatus (TFF) (standardized mean difference [SMD] = -1.14, 95% confidence interval [CI]: -1.54 to -0.73, P < 0.00001), time to first defecation (TFD) (SMD = -1.31, 95% CI: -1.88 to -0.74, P < 0.00001), time to bowel sounds recovery (TBSR) (SMD = -1.57, 95% CI: -2.14 to -1.01, P < 0.00001), and length of hospital stay (LOS) (mean difference [MD] = -1.68, 95% CI: -2.55 to -0.80, P = 0.0002) compared with usual care. A subgroup analysis found that acupuncture at distal acupoints once daily after surgery had superior effects on reducing TFF and TFD. A sensitivity analysis supported the validity of the finding. Acupuncture also manifested an effect of reducing TFF, TFD and TBSR compared with sham acupuncture but the result was not stable. Relatively few trials have reported whether adverse events have occurred. CONCLUSIONS: Acupuncture showed a certain effect in reducing POI following GI surgery with very low-to-moderate quality of evidence. The overall safety of acupuncture should be further validated. More high-quality, large-scale, and multicenter original trials are needed in the future.

Effect of modifying high-risk factors and prehabilitation on the outcomes of colorectal cancer surgery: controlled before and after study.

BACKGROUND: Low functional capacity, malnutrition, and anaemia are associated with an increased risk of complications after surgery. These high-risk indicators can be improved through preoperative interventions. The aim of the study was to examine the effect of screening for modifiable high-risk factors combined with targeted interventions on postoperative complications in patients undergoing colorectal cancer surgery. METHODS: A controlled before-and-after study was conducted including patients with colorectal cancer undergoing elective curative surgery between August 2015 and October 2018, in two institutions (intervention and control hospital). The intervention consisted of a screening for anaemia, low functional capacity, and nutritional status and their implementation (iron supplementation, prehabilitation, nutritional supplements, and consultation with a dietician), for a minimum of 4 weeks before surgery. The primary outcome was a composite measure consisting of unplanned admission to the intensive care unit, complications with Clavien-Dindo score of 3a or above, length of hospital stay less than 10 days, readmission, or death within 30 days during the postoperative course. RESULTS: A total of 1591 patients were included for analysis with 839 at the intervention hospital and 752 at the control hospital. In a difference-in-difference analysis, adjusted for age, sex, smoking, stage of disease, ASA score, surgical approach, and surgical procedure, the intervention was associated with a 10.9 per cent (95 per cent c.i. 2.1 to 19.7 per cent) absolute risk reduction of a complicated postoperative course, primarily due to a reduction in severe complications. CONCLUSION: The combined intervention of screening and prehabilitation was associated with a decreased risk of a complicated course, primarily in a reduction of severe complications.

Autologous gastrointestinal reconstruction surgery for short bowel syndrome: the cornerstone for intestinal rehabilitation.

PURPOSE OF REVIEW: Intestinal failure (IF) evolved from being the last recognized organ failure, to become one of the most progressive fields in terms of therapeutic alternatives and results. Short bowel syndrome (SBS) is the main cause of IF in adults and children. The use of surgery allowed patients with unfavorable anatomy type and length to be wean off parenteral nutrition. We aim to evaluate its current impact on intestinal rehabilitation. RECENT FINDINGS: Autologous gastro-intestinal reconstructive surgery (AGIRS), including bowel lengthening contributes by converting patient's anatomy to a more favorable one, improving quality of life, and modifying the natural history of the disease, allowing to recover intestinal autonomy in approximately 70% of the adults and 50% of the children's with SBS-IF. The current use of postsurgical medical rehabilitation strategies including the use of enterohormones complement the path to sufficiency, increasing the chances of success in both age group of patients. SUMMARY: The development of AGIRS has changed the outcome of SBS-IF patients, becoming the main surgical procedure prescribed in multidisciplinary units, allowing to enhance the number of patients achieving intestinal autonomy throughout rehabilitation, leaving transplantation as the last surgical alternative.

Effect of Postoperative Coffee Consumption on Postoperative Ileus after Abdominal Surgery: An Updated Systematic Review and Meta-Analysis.

BACKGROUND: Previous systematic reviews have not clarified the effect of postoperative coffee consumption on the incidence of postoperative ileus (POI) and the length of hospital stay (LOS). We aimed to assess its effect on these postoperative outcomes. METHODS: Studies evaluating postoperative coffee consumption were searched using electronic databases until September 2021 to perform random-effect meta-analysis. The quality of evidence was assessed using the Cochrane risk-of-bias tool. Caffeinated and decaffeinated coffee were also compared. RESULTS: Thirteen trials (1246 patients) and nine ongoing trials were included. Of the 13 trials, 6 were on colorectal surgery, 5 on caesarean section, and 2 on gynecological surgery. Coffee reduced the time to first defecation (mean difference (MD) -10.1 min; 95% confidence interval (CI) = -14.5 to -5.6), POI (risk ratio 0.42; 95% CI = 0.26 to 0.69); and LOS (MD -1.5; 95% CI = -2.7 to -0.3). This trend was similar in colorectal and gynecological surgeries. Coffee had no adverse effects. There was no difference in POI or LOS between caffeinated and decaffeinated coffee (p > 0.05). The certainty of evidence was low to moderate. CONCLUSION: This review showed that postoperative coffee consumption, regardless of caffeine content, likely reduces POI and LOS after colorectal and gynecological surgery.

Massive cerebral air embolism following percutaneous transhepatic biliary drainage: A case report.

RATIONALE: Cerebral air embolism from portal venous gas rarely occurs due to invasive procedures (e.g., endoscopic procedures, liver biopsy, or percutaneous transhepatic biliary drainage) that disrupt the gastrointestinal or hepatobiliary structures. Here, we report a rare case of fatal cerebral air embolism following a series of percutaneous transhepatic biliary drainage tube insertions. PATIENT CONCERNS: A 50-year-old woman with a history of cholecystectomy, liver wedge resection, and hepaticojejunostomy for gallbladder cancer presented with altered mental status 1 week after percutaneous transhepatic biliary drainage tube placement. DIAGNOSES: Extensive cerebral air embolism and acute cerebral infarction. INTERVENTIONS: Brain computed tomography and magnetic resonance imaging, hyperbaric oxygen therapy, medical therapy. OUTCOMES: Despite the use of hyperbaric oxygen therapy and medical treatment including vasopressors, the patient eventually died due to massive systemic air embolism. LESSONS: To date, there have been no reports of cerebral air embolism due to percutaneous transhepatic biliary drainage with pronounced radiologic images. We reviewed previously reported fatal cases associated with endoscopic hepatobiliary procedures and assessed the possible mechanisms and potential causes of air embolism.

Clinical Impact of Perioperative Oral Nutritional Treatment for Body Composition Changes in Gastrointestinal Cancer Treatment.

The standard treatment for gastrointestinal cancer is surgical resection and perioperative adjuvant treatment. Multidisciplinary treatment for gastrointestinal cancer leads to body composition changes. Body composition changes, such as skeletal muscle loss and body weight loss, during multidisciplinary treatment result in poor physical activity, severe toxicity of chemotherapy and/or radiation therapy, and poor oncological outcomes. Therefore, the hypothesis is that minimization of body composition changes during multidisciplinary treatment in gastrointestinal cancer patients, the continuation of postoperative adjuvant treatment in these patients might improve, thereby improving the oncological outcomes. Given this hypothesis, recent studies have focused on introducing perioperative oral nutritional treatment for gastrointestinal cancer patients. Thus far, oral nutritional treatment has proven promising and showed some clinical benefits for gastrointestinal cancer patients during the perioperative period. However, whether or not oral nutritional treatment has clinical benefits on the long-term oncological outcomes in gastrointestinal cancer remains unclear. To optimize oral nutritional treatment for gastrointestinal cancer patients, it is necessary to clarify the benefits of oral nutritional treatment on the long-term oncological outcomes in gastric cancer patients and establish the optimal approach to oral nutritional treatment.

Sacral neuromodulation for the prevention of a permanent stoma in patients with severe defecation disorder following intersphincteric resection.

PURPOSE: Severe defecation disorder occurs frequently in coloanal anastomosis for low rectal cancer, and may affect quality of life. Sacral neuromodulation (SNM) has been reported to be successful after rectal resection, but there are no results for patients treated with intersphincteric resection (ISR). METHODS: A retrospective single-center study of SNM was performed for patient with defecation disorder following ISR. Pre- and post-treatment bowel frequencies, fecal incontinence episodes, and Wexner, LARS and FIQL scores were assessed to evaluate the efficacy. A good response was defined as ≥ 50% reduction of bowel frequency per day or fecal incontinence episodes per week. RESULTS: 10 patients (7 males, mean age 67.5 years) underwent SNM. All patients had severe fecal incontinence with a median Wexner score of 15 (13-20) and a median LARS score of 41 (36-41). The Wexner score improved after SNM, but not significantly (p = 0.06). LARS and FIQL scores significantly improved after SNM (p = 0.02, p = 0.01). At the end of follow-up, the good response rate was 40%. Three cases without a good response required creation of a permanent stoma. CONCLUSION: Seven out of 10 patients did not require a permanent colostomy after SNM. SNM should be considered before performing a permanent colostomy.

Constipation after surgery for anorectal malformations: Unrecognised problem until it is a problem.

BACKGROUND: Constipation is a common problem after surgery for anorectal malformations (ARMs), especially in patients having preserved rectosigmoid after pull-down surgery. Here, we present our experience with patients having constipation after surgery for ARMs and briefly discuss its management. MATERIALS AND METHODS: We retrospectively reviewed electronic operative and follow-up data from January 2015 to December 2019 of all patients having constipation after surgery for ARMs. RESULTS: A total of 77 patients were included in the study. The median age was 60 months, and thirty patients were male. Primary diagnoses were rectourethral fistula (26; 33.77%), vestibular fistula (25; 32.47%), perineal fistula/ectopic anus (18; 23.38%), rectovaginal fistula (4; 5.19%) and imperforate anus without fistula (4; 5.19%). Anal stenosis was found in 20 (25.97%) patients, posterior ledge with an adequate anal opening in 5 (6.49%), displaced anus in 4 (5.19%) but no obvious problem found in 48 (62.34%) patients. Non-operative management was successful in 75.44% (43 out of 57) of patients. Surgery was performed in 32 out of 77 patients (41.56%) with no mortality. Forty-three (72.88%) patients are continent, stayed clean, but 16 (27.19%) patients still need some sort of laxative/bowel wash/enema intermittently (Grade I/II constipation). Incidence of constipation was higher in patients operated through anterior sagittal route (27.58%) than posterior sagittal route (23.94%), but it was not statistically significant (P = 0.479). Follow-up ranged from 3 months to 5 years. CONCLUSION: Constipation is a common problem after ARMs surgery, especially in patients having preserved rectosigmoid after pull-down surgery. It is advisable to create relatively larger neoanus after pull through with early practice of neoanus dilatation, especially in redo cases. Repeated counselling, laxatives and dietary manipulations should begin at the first sign of constipation.

Combined use of advanced practice providers and care pathways reduces the duration of stay after surgery for gastrointestinal malignancies.

BACKGROUND: The gastrointestinal surgical oncology service at our comprehensive cancer center sought to improve the quality of postsurgical inpatient care while increasing discharge efficiency. METHODS: A stakeholder team established standard postsurgical care pathways and dedicated inpatient advanced practice provider positions. We compared postsurgical length of stay before (July 2017 to April 2018) and after (May 2018 to April 2019) the interventions using Wilcoxon rank-sum tests. We benchmarked length of stay to National Surgical Quality Improvement Project and Centers for Medicare and Medicaid Services geometric mean length of stay. We also compared readmission rates and surgeon-specific Hospital Consumer Assessment of Health Care Provider and Systems and Press-Ganey scores. RESULTS: There were 462 cases before and 563 after the interventions. Postintervention, median length of stay decreased from 6.50 to 6.00 days (P = .017). There was a ≥1-day reduction for 10 of 14 case types with significant length of stay decreases for robotic esophagectomy (P = .001), liver resection (P = .023), and cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (P = .030). More case types met or exceeded Centers for Medicare and Medicaid Services and National Surgical Quality Improvement Project benchmarks after the interventions. Readmission rates were stable (preintervention 9.3%, postintervention 10.3%, P = .585). Press-Ganey and HCAHPS measures were stable or improved in all evaluated domains. CONCLUSION: Incorporating advanced practice providers and care pathways into gastrointestinal surgical oncology inpatient care was associated with reduced length of stay without declination in readmission rates or patient experience measures.

Effect of long-lasting nutritional prehabilitation on postoperative outcome in elective surgery for IBD.

BACKGROUND & AIMS: Preoperative patient care optimisation appears to be crucial for obtaining good surgical outcomes. Enhanced Recovery After Surgery (ERAS) underlines the necessity to recognize and treat malnutrition perioperatively and to prehabilitate with interventions that can modulate the lean body mass before and after surgery. This procedure has been extensively reported in colorectal cancer patients but in Inflammatory Bowel Disease (IBD) it has not yet been clearly evaluated. The aim of this study was to implement the perioperative nutritional items in surgical Crohn's disease (CD) and ulcerative colitis (UC) patients electively operated in an ERAS setting, thus to clarify the impact of a long-lasting prehabilitation program in IBD. METHODS: Consecutive adult patients (age ≥18) were included as soon as scheduled for elective surgery for CD or UC. The nutritional intervention included personalized dietary counseling and oral nutritional supplements when necessary. Data prospectively recorded in each phase were: FFM, FM, FFMI and phase angle detected with BIVA, weight, BMI, unintended weight loss, DASI, energy and nutritional intake, gastrointestinal symptoms and bowel functions. Nutritional risk was detected according to the NRS 2002 screening tool. The impact of early oral nutrition on postoperative recovery was analysed. RESULTS: A total of 61 IBD patients (45 CD and 16 UC) were included. Muscle wasting was present at baseline assessment in 28% of cases, significantly associated with the presence of ileostomy (p < 0.011) and of a previous IBD surgery (p < 0.011). During the preoperative phase, there was a significant improvement in weight, BMI, FFM (CD p = 0.035; UC p = 0.017), FFMI (CD ns; UC p = 0.011) and phase angle (CD p = 0.014; UC p = 0.027). During the intra-hospital phase, weight and FFM decreased due to the catabolic effect of surgery, but in the whole perioperative period, both CD and UC patients did not change significantly in terms of body composition. Patients with earlier resumption of oral feeding had a significantly shorter hospital stay and a faster recovery of bowel function with no significant relationship with early postoperative complications. CONCLUSIONS: Nutritional prehabilitation positively modulated the body composition of IBD patients scheduled for elective surgery and therefore could represent a beneficial strategy to attenuate the impact of the surgical stress response on lean tissue in an ERAS setting. This effect is even more evident in high nutritional risk patients. Early postoperative oral feeding seems feasible and well tolerated in IBD.

Effect of Guided Imagery Along With Breathing Relaxation on Sleep Quality of the Elderly Patients Under Abdominal Surgery: A Randomized Clinical Trial.

Elderly patients undergoing surgery often suffer from sleep disorder. Holistic therapies might help them sleep better. The aim of this research was to determine the effect of guided imagery along with breathing relaxation on sleep quality in elderly patients undergoing abdominal surgery. A double-blind randomized clinical trial was conducted on 90 elderly patients undergoing abdominal surgery in 2 educational hospitals in 2018, Mashhad, Iran. The elderly patients with different abdominal surgical procedures were distributed to the wardrooms and then the rooms were randomly assigned into 2 groups. In the intervention group, the patients learned breathing relaxation the day before surgery and then an audiotape was provided to perform the guided imagery from the day before surgery for 5 days (twice) along with breathing relaxation. St Mary's Hospital Sleep Inventory was completed the night before, 48 hours and 96 hours after the surgery. Data analysis was done using SPSS 21 through analytical tests. Results of the test indicated that the score of sleep quality was significantly higher in the intervention group the night before surgery (P = .001). The total scores of sleep quality in the intervention group 48 and 96 hours after the surgery were significantly higher (P < .001). Based on results of generalized estimating equation model, the score of sleep quality for patients was 8.76 units higher in the intervention group than in the control group by controlling for the effects of time. Guided imagery along with breathing relaxation improved the sleep quality of the elderly patients undergoing abdominal surgery.Trial registration: IRCT20180731040652N1.

Surgical Interventions for Functional Constipation: An Update.

Chronic idiopathic constipation, also known as functional constipation, is defined as difficult and infrequent defecation without an identifiable organic cause. Medical management with laxatives is effective for the majority of constipated children. However there is a subset of patients who may need evaluation by a surgeon. As constipation progresses, it can lead to fecal retention and rectal and sigmoid distension, which impairs normal colorectal motility. Surgical interventions are influenced by the results of: a rectal biopsy, transit studies, the presence of megacolon/megarectum on contrast enema, the degree of soiling/incontinence, anorectal manometry findings, and colonic motility evaluation. In this review, we describe the different surgical options available (intestinal diversion, antegrade enemas, sacral nerve stimulation, colonic resections, and Botulinum toxin injection) and provide guidance on how to choose the best procedure for a given patient.

Pathophysiology, prevention, and treatment of beriberi after gastric surgery.

Beriberi is a nutritional complication of gastric surgery, caused by deficiency of vitamin B1, or thiamine. Thiamine deficiency leads to impaired glucose metabolism, decreased delivery of oxygen by red blood cells, cardiac dysfunction, failure of neurotransmission, and neuronal death. This review describes the history and pathophysiology of beriberi as well as the relationship between beriberi and nutritional deficiencies after gastric surgery. A literature review of the history and pathophysiology of beriberi and the risk factors for thiamine deficiency, particularly after gastric resection or bariatric surgery, was performed. Recommendations for nutritional follow-up post gastric surgery are based on current national guidelines. Patients may have subclinical thiamine deficiency after upper gastrointestinal surgery, and thus beriberi may be precipitated by acute illness such as sepsis or poor dietary intake. This may occur very soon or many years after gastrectomy or bariatric surgery, even in apparently well-nourished patients. Prompt recognition and administration of supplemental thiamine can decrease morbidity and mortality in patients with beriberi. Dietary education post surgery and long-term follow-up to determine nutritional status, including vitamin and mineral assessment, is recommended for patients who undergo gastric surgery.
