Exploring the Belly of the Beast: A Systematic Review of Gastrointestinal Symptoms Following Mammoplasty Procedures.

BACKGROUND AND AIMS: Mammoplasty, a common cosmetic procedure involving breast augmentation and reduction surgeries, has gained global popularity. Recently, attention has shifted towards understanding the prevalence and significance of gastrointestinal (GI) symptoms following mammoplasty. This systematic review aims to consolidate existing literature to provide a comprehensive overview of the type and frequency of GI problems associated with various mammoplasty procedures. METHODS: A systematic search of PubMed and Scopus databases was conducted until January 22, 2024, identifying observational and interventional studies examining GI symptoms post-mammoplasty. Inclusion criteria covered human studies, while exclusion criteria ensured specificity. Two independent investigators performed screening, and data extraction included study characteristics, surgical procedures, anesthesia methods, and interventions. RESULTS: Nineteen studies, involving 2,487 subjects, were included in the review. Breast reconstruction emerged as the most studied procedure, followed by breast reduction, augmentation, mastectomy, and breast cancer surgery. Predominant GI symptoms included nausea and vomiting, with varying rates across mammoplasty types. Anesthesia modality influenced symptomatology, with general, local, and combined anesthesia associated with GI disturbances. Antiemetics, notably ondansetron and droperidol, showed variable efficacy. Non-pharmacological approaches, such as preoperative hypnosis, were explored for symptom management. CONCLUSIONS: Our systematic review reveals insights into GI symptoms post-mammoplasty, emphasizing the common occurrence of symptoms such as nausea and vomiting, alongside less frequent manifestations such as constipation, dry mouth, retching, abdominal pain, and tightness. Variations in symptom prevalence were noted across diverse mammoplasty surgeries, anesthesia methods, and the use of antiemetics, underscoring the complex nature of post-mammoplasty GI disturbances.

A randomized phase 2 study of the 5-HT4 receptor agonist felcisetrag for postoperative gastrointestinal dysfunction after bowel surgery.

BACKGROUND: Felcisetrag (5-hydroxytryptamine-4 receptor [5-HT4] agonist) is under investigation as prophylaxis or active treatment for accelerating resolution of gastrointestinal function post-surgery. METHODS: Phase 2, randomized, placebo-controlled, parallel five-arm, double-blind, multicenter study (NCT03827655) in 209 adults undergoing open or laparoscopic-assisted bowel surgery. Patients received intravenous placebo, felcisetrag 0.1 mg/100 â€‹mL or 0.5 mg/100 â€‹mL pre-surgery only, or pre-surgery and daily post-surgery until return of gastrointestinal function or for up to 10 days. PRIMARY ENDPOINT: time to recovery of gastrointestinal function. RESULTS: Median time to recovery of gastrointestinal function was 2.6 days for both felcisetrag 0.5 â€‹mg daily and 0.5 â€‹mg pre-surgery versus 1.9 days for placebo (p â€‹> â€‹0.05). There were no notable differences in adverse events between treatment arms. CONCLUSIONS: Felcisetrag was well tolerated with no new safety concerns. However, no clinically meaningful difference in time to recovery of gastrointestinal function versus placebo was observed. Further investigation of the utility of 5-HT4 agonists in complicated, open abdominal surgeries may be warranted.

The contribution of EUS to the management of endoscopic and surgical complications.

Endoscopic Ultrasound (EUS) stands as a remarkable innovation in the realm of gastroenterology and its allied disciplines. EUS has evolved to such an extent that it now assumes a pivotal role in both diagnosis and therapeutics. In addition, it has developed as a tool which is also capable of addressing complications arising from endoscopic and surgical procedures. This minimally invasive technique combines endoscopy with high-frequency ultrasound, facilitating, high-resolution images of the gastrointestinal tract and adjacent structures. Complications within the gastrointestinal tract, whether stemming from endoscopic or surgical procedures, frequently arise due to disruption in the integrity of the gastrointestinal tract wall. While these complications are usually promptly detected, there are instances where their onset is delayed. EUS plays a dual role in the management of these complications. Firstly, in its ability to assess and increasingly to definitively manage complications through drainage procedures. It is increasingly employed to manage post-surgical collections, abscesses biliary strictures and bleeding. Its high-resolution imaging capability allows precise real-time visualisation of these complications.

Endoscopic application of magnetic compression anastomosis: a review.

Magnetic compression anastomosis (MCA) is a new method that provides sutureless passage construction for tubular organs. Due to the high recurrence rate of conventional endoscopic treatment and the high morbidity and mortality of surgical procedures, the MCA technique shows promise. The aim of this review is to comprehensively examine the literature related to the use of MCA in different gastrointestinal diseases over the past few years, categorizing them according to the anastomotic site and describing in detail the various methods of magnet delivery and the clinical outcomes of MCA. MCA is an innovative technique, and its use represents an advancement in the field of minimally invasive interventions. Comparison studies have shown that the anastomosis formed by MCA is comparable to or better than surgical sutures in terms of general appearance and histology. Although most of the current research has involved animal studies or studies with small populations, the safety and feasibility of MCA have been preliminarily demonstrated. Large prospective studies involving populations are still needed to guarantee the security of MCA. For technologies that have been initially used in clinical settings, effective measures should also be implemented to identify, even prevent, complications. Furthermore, specific commercial magnets must be created and optimized in this emerging area.

Applicability of sodium butyrate preparations from a surgeon's and gastroenterologist's perspective.

In recent years, much has been written about the possibilities of using exogenous sodium butyrate in the prevention and treatment of gastrointestinal diseases, in prehabilitation, in peri- and postoperative treatment, as well as its local application. It became possible thanks to the development of a special formulation (microencapsulation technique) enabling the delivery of unstable butyrate compounds to the large intestine, where it is used primarily as a source of energy. It also plays a key role in maintaining body homeostasis by maintaining the integrity of the intestinal epithelium and stimulating the intestinal immune system. There is growing evidence of the effectiveness of sodium butyrate in various areas of health. The following article discusses the possibilities of using microencapsulated sodium butyrate in the prevention and treatment of gastrointestinal diseases from the perspective of a gastroenterologist and gastrointestinal surgeon.

Persistent and newly developed gastrointestinal symptoms after surgery for intestinal malrotation in children: Dysmotility or disorders of gut and brain interaction?

OBJECTIVES: Surgery for intestinal malrotation (IM) aims to correct the defect and improve symptoms; however, many have persistent gastrointestinal (GI) symptoms postoperatively. We evaluated the incidence, clinical presentation, and long-term outcomes of children with surgically repaired IM and its possible association with disorders of gut and brain interaction (DGBI). METHODS: Multicenter retrospective study was conducted in patients from 0 to 21 years old, who had surgery for IM from 2000 to 2021 across three pediatric tertiary care centers. Data analyzed included demographics, time to diagnosis, idiopathic diagnosis, incidental diagnosis, postoperative follow-up, surgical time, and the need for surgery including bowel detorsion. Outcome variables were the presence of postoperative GI symptoms and DGBIs, and overall resolution of symptoms. We also evaluated the potential association of demographics and other included variables with our outcome variables. RESULTS: Ninety-two patients with surgically corrected IM were included, 54% were male, and median age of diagnosis and surgical correction was 4.9 and 7.8 months, respectively. Median follow-up after surgery was 64 months. A total of 77% had postoperative GI symptoms, and notably, 78% of patients without symptoms before surgery (incidental diagnosis) developed GI symptoms postoperatively and 27% of patients met Rome IV criteria for a one or more DGBI. No factors were associated to the presence of postoperative symptoms or DGBIs in multivariate analysis. Female gender was the only factor associated with lack of resolution of symptoms at follow-up. CONCLUSION: Pediatric IM is commonly associated with postoperative GI symptoms and DGBI well beyond surgery. An increased awareness about the prevalence of DGBI in these patients may help reach a prompt and accurate diagnosis, and improve their quality of life.

Abdominal computed tomography and exploratory laparotomy have high agreement in dogs with surgical disease.

OBJECTIVE: To compare the results of abdominal CT with exploratory laparotomy in the dog. ANIMALS: 100 client-owned dogs from 1 academic institution. METHODS: Medical records were searched for dogs that had undergone a preoperative abdominal CT scan read by a board-certified veterinary radiologist followed by an exploratory laparotomy. CT and surgical reports were compared. RESULTS: The overall agreement between abdominal CT scan and exploratory laparotomy in all cases was 97%. Overall, there was no evidence that proportion agreement differed on the basis of body condition score, time interval between CT and surgery, or oncologic versus nononcologic disease. CLINICAL RELEVANCE: Abdominal CT scan read by a board-certified diplomate is a sensitive presurgical diagnostic tool for surgical abdominal disease in the dog. When performing a specific abdominal surgery, it is acceptable for the surgeon to fully explore the abdomen or forego it for a smaller approach to the organ of interest if an abdominal CT was performed prior.

Persistent urinary incontinence in female Golden Retrievers following laser ablation of intramural ectopic ureters may be associated with the presence of historical urinary tract infection.

OBJECTIVE: To identify predictive factors for postoperative continence in female Golden Retrievers following cystoscopic-guided laser ablation of intramural ectopic ureters (CLA-EU). ANIMALS: 41 client-owned female entire Golden Retrievers with uni- or bilateral intramural ectopic ureter(s) were retrospectively enrolled. METHODS: Patients were diagnosed with ectopic ureters with a combination of ultrasonography and cystoscopy. CLA-EU was performed for all dogs so that each ureteral opening was considered to be in an appropriate position by a single operator. All dogs had short-term follow-up 4 weeks and long-term follow up > 10 weeks after the procedure via telephone, which included urinary continence scoring. Clinical factors and ultrasonographic and cystoscopic findings from initial presentation were evaluated to identify predictive factors for postoperative continence. RESULTS: Short-term urinary continence was achieved in 46.3% of dogs with no additional medical therapies. Presence of historical urinary tract infections prior to CLA-EU (OR, 0.130; 95% CI, 0.020 to 0.621; P = .018) was negatively correlated and ureteral dilatation (OR, 34.260; 95% CI, 1.813 to 2,143; P = .043) was positively correlated with likelihood of urinary continence. Long-term urinary continence was achieved in 63.4% of dogs, and presence of historical urinary tract infections was negatively prognostic (OR, 0.173; 95% CI, 0.023 to 0.856; P = .048). CLINICAL RELEVANCE: Female Golden Retrievers undergoing CLA-EU have similar outcomes to those reported for other mixed-breed cohorts with > 30% of dogs failing to regain urinary continence. Historical urinary tract infections were significantly associated with both short- and long-term urinary continence in our population.

Feasibility of S-1 adjuvant chemotherapy after major hepatectomy for biliary tract cancers: An exploratory subset analysis of JCOG1202.

INTRODUCTION: Major hepatectomy (MH) may produce the impaired liver function and affect the feasibility of adjuvant chemotherapy in terms of early period after the surgery, but there have not been detailed investigations. JCOG1202 (UMIN000011688) is a randomized phase III trial demonstrating the superiority of adjuvant S-1 chemotherapy for biliary tract cancer (BTC). The aim of this study is to examine the influence of MH for BTC on adjuvant S-1. MATERIALS AND METHODS: Of the total 424 patients, 207 received S-1 (S-1 arm) while the remaining 217 were not. We compared MH with non-major hepatectomy (NMH) for BTC. RESULTS: In the S-1 arm, 42 had undergone MH, and 165 had undergone NMH. MH had similar pretreatment features to NMH, including the proportion of biliary reconstruction, to NMH, except for a lower platelet count (17.7 vs. 23.4 × 104/mm3, p < 0.0001) and lower serum albumin level (3.5 vs. 3.8 g/dL, p < 0.0001). The treatment completion proportion tended to be lower for MH than for NMH (59.5 % vs. 75.8 %; risk ratio, 0.786 [95 % confidence interval, 0.603-1.023], p = 0.0733), and the median dose intensity was lower as well (88.7 % vs. 99.6 %, p = 0.0358). The major reasons for discontinuation were biliary tract infections and gastrointestinal disorders after MH. The frequency of grade 3-4 biliary tract infection was 19.0 % in MH vs. 4.2 % in NMH. CONCLUSION: The treatment completion proportion and dose intensity were lower in MH than in NMH. Caution should be exercised against biliary tract infections and gastrointestinal disorders during adjuvant S-1 after MH for BTC.

Regular use of low-dose of opioids after gastrointestinal surgery may lead to postoperative gastrointestinal tract dysfunction in children: a Chinese national regional health center experience sharing.

BACKGROUND: The need for pain management is increasing in pediatrics, but the side effects of overuse or abuse of analgesics can be harmful to children's health and even life-threatening in severe cases. METHODS: Patients who underwent resection of Meckel's diverticulum at the Children's Hospital of Chongqing Medical University from July 1, 2019, to July 1, 2022, were included in this study. Opioids were administered through patient-controlled analgesia (PCA). Based on the preoperative choices made by the legal guardians, patients were stratified into two groups: PCA Group (PCAG) and Non-PCA Group (NPCAG). Data pertaining to the clinical characteristics and prognoses of these patients were subsequently collected and analyzed to assess the impact of opioid administration. RESULTS: In the study, a total of 126 patients were enrolled, with 72 allocated to the Patient-Controlled Analgesia Group (PCAG) and 54 to the Non-Patient-Controlled Analgesia Group (NPCAG). When compared to the NPCAG, the PCAG exhibited a longer duration of postoperative fasting (median 72 vs. 62 h, p = 0.044) and increased utilization of laxatives (12[16.7%] vs. 2[3.7%], p = 0.022). However, the PCAG also experienced higher incidences of intestinal stasis and abnormal intestinal dilation (13[18.1%] vs. 3[5.6%], p = 0.037). No statistically significant differences were observed in pain assessments at the conclusion of the surgical procedure (0 vs. 1[1.9%], p = 0.429) or within the first 24 h postoperatively (16[22.2%] vs. 18[33.3%], p = 0.164). Additionally, NPCAG patients did not necessitate increased administration of rescue analgesics (2[2.8%] vs. 4[7.4%], p = 0.432). CONCLUSIONS: The administration of opioids did not demonstrably ameliorate postoperative pain but was associated with a heightened incidence of postoperative gastrointestinal tract dysfunction. The retrospective nature of the current research should be considered and should be clarified further.

Incidence and risk factors for postoperative gastrointestinal dysfunction occurrence after gastrointestinal procedures in US patients.

BACKGROUND: Incidence of, and potential risk factors for, postoperative gastrointestinal dysfunction (POGD) after gastrointestinal procedures performed in US hospitals were examined. METHODS: This retrospective study used hospital discharge data of inpatients who underwent ≥1 gastrointestinal procedures from 1-Jan-2016 to 30-Apr-2019. POGD incidence was calculated based on all hospitalizations for MDC-06 procedures. Predictors of POGD were assessed using multivariable logistic regression. RESULTS: POGD incidence was 5.8% among 638 611 inpatient hospitalizations. Major bowel procedures, peritoneal adhesiolysis, and appendectomy were the most notable predictors of POGD among gastrointestinal procedures assessed (adjusted odds ratios [95% confidence intervals]: 2.71 [2.59-2.83], 2.48 [2.34-2.64], and 2.15 [2.03-2.27], respectively; all p < 0.05). Procedures performed by colorectal/gastroenterology specialists (0.86 [0.84-0.89]), and those performed percutaneously (0.55 [0.54-0.56]) were associated with significantly lower odds of POGD (both P < 0.05). CONCLUSIONS: Findings may help clinicians tailor management plans targeting patients at high-risk of POGD.

Lumen-apposing metal stents for the treatment of benign gastrointestinal tract strictures: a single-center experience and proposed treatment algorithm.

BACKGROUND: Lumen-apposing metal stents (LAMS) are an alternative therapeutic option for benign gastrointestinal (GI) tract strictures. Our study aimed to evaluate the safety and efficacy of LAMS for the management of benign GI strictures. METHODS: Consecutive patients who underwent a LAMS placement for benign luminal GI strictures at a tertiary care center between January 2014 and July 2021 were reviewed. Primary outcomes included technical success, early clinical success, and adverse events (AEs). Other outcomes included rates of stent migration and re-intervention after LAMS removal. RESULTS: One hundred and nine patients who underwent 128 LAMS placements (67.9% female, mean age of 54.3 ± 14.2 years) were included, and 70.6% of the patients had failed prior endoscopic treatments. The majority of strictures (83.5%) were anastomotic, and the most common stricture site was the gastrojejunal anastomosis (65.9%). Technical success was achieved in 100% of procedures, while early clinical success was achieved in 98.4%. The overall stent-related AE rate was 25%. The migration rate was 27.3% (35/128). Of these, five stents were successfully repositioned endoscopically. The median stent dwell time was 119 days [interquartile range (IQR) 68-189 days], and the median follow-up duration was 668.5 days [IQR: 285.5-1441.5 days]. The re-intervention rate after LAMS removal was 58.3%. CONCLUSIONS: LAMS is an effective therapeutic option for benign GI strictures, offering high technical and early clinical success. However, the re-intervention rate after LAMS removal was high. In select cases, using LAMS placement as destination therapy with close surveillance is a reasonable option.

Characterizing gastrointestinal dysfunction after pancreatic resection: a single-center retrospective study.

BACKGROUND: There are many well-described potential gastrointestinal (GI) side effects of pancreatic resection that can cause patients to suffer from chronic malabsorption, diarrhea, and persistent nausea. These GI symptoms can affect postoperative recovery, initiation of adjuvant therapy, and overall quality of life (QOL). The purpose of this study is to quantify the incidence of post-procedural complications and identify patients at higher risk for experiencing GI dysfunction after pancreatectomy. METHODS: A retrospective review of patients who underwent pancreatic resection at a single institution between January 2014 and December 2019 was performed. Demographics, operative factors, and postoperative gastrointestinal symptomatology and treatments were obtained by chart review. Significance tests were performed to compare GI dysfunction between patient subgroups. RESULTS: A total of 545 patients underwent pancreatic resection; within the cohort 451 patients (83%) underwent a pancreaticoduodenectomy (PD) and the most common indication was pancreatic adenocarcinoma. Two-thirds of patients (67%) reported gastrointestinal symptoms persisting beyond hospitalization. Only 105 patients (20%) were referred to gastroenterology for evaluation with 30 patients (5.5%) receiving a formal diagnosis. Patients who underwent PD were more likely to report GI symptoms and patients who identified as Caucasian were more likely to be referred to gastroenterology for evaluation. CONCLUSIONS: Gastrointestinal dysfunction after pancreatic resection occurs frequently yet only a small percentage of patients are referred for formal testing and diagnosis. There also appears to be a racial difference in referral patterns. Patients would benefit if earlier attention was dedicated to the diagnosis and corresponding treatment for postoperative digestive health disorders to optimize treatment planning and QOL.
