Placement of Nasogastric Tubes in Pancreaticoduodenectomy Patients: Switching from Immediate Intraoperative Removal to Avoiding Unnecessary Perioperative Use.

BACKGROUND: The placement of nasogastric tubes (NGTs) in abdominal surgery has been adopted for decades to attenuate ileus and prevent aspiration pneumonia. In the recent era, the guidelines recommend not using NGT routinely, and even in pancreaticoduodenectomy (PD), immediate removal of NGT in operating rooms (ORs) was suggested. However, the clinical outcome and safety of abandoning NGT during the pre-PD and intra-PD periods remain unknown. METHODS: We conducted a single-center retrospective review on adult PD patients aged between 20 and 75 years from 2013 to 2022. The study population was grouped into the NGT group (NGT was placed before PD and immediately removed in the ORs) and the non-NGT group (NGT was not placed preoperatively). Safety was evaluated by the number of adverse events. The primary aim of this study is to evaluate the need of NGT insertion in ORs among PD patients. RESULTS: The case numbers in the NGT and non-NGT groups were 391 and 578, respectively. No case in the non-NGT group needed the intraoperative insertion of NGT. The rate of pulmonary complications was 2.3% in the NGT group compared to 1.6% in the non-NGT group (P = 0.400). Furthermore, there were no significant differences in terms of rates of major complications (12.8% vs. 9.3%, P = 0.089) or mortality (1.0% vs. 1.0%, P =0.980) between the two groups. The rates of the postoperative insertion of NGT in the NGT and non-NGT groups were 2.6% and 2.8% (P = 0.840), respectively. CONCLUSION: For selected PD patients, the placement of NGT during pre-PD and intra-PD periods may be safely omitted. This primary study is considered the first foundation stone in the extension of the element of no NGT in PD.

Esophagectomy Enhanced Recovery After Surgery Initiative Results in Improved Outcomes.

BACKGROUND: Esophagectomy for esophageal cancer is a procedure with high morbidity and mortality. This study developed a Multidisciplinary Esophagectomy Enhanced Recovery Initiative (MERIT) pathway and analyzed implementation outcomes in a single institution. METHODS: The MERIT pathway was developed as a practice optimization and quality improvement initiative. Patients were studied from November 1, 2021 to June 20, 2022 and were compared with historical control subjects. The Wilcoxon rank sum test and the Fisher exact test were used for statistical analysis. RESULTS: The study compared 238 historical patients (January 17, 2017 to December 30, 2020) with 58 consecutive MERIT patients. There were no significant differences between patient characteristics in the 2 groups. In the MERIT group, 49 (85%) of the patients were male, and their mean age was 65 years (range, 59-71 years). Most cases were performed for esophageal cancer after neoadjuvant therapy. Length of stay improved by 27% from 11 to 8 days (P = .27). There was a 12% (P = .05) atrial arrhythmia rate reduction, as well as a 9% (P = .01) decrease in postoperative ileus. Overall complications were reduced from 54% to 35% (-19%; P = .01). CONCLUSIONS: This study successfully developed and implemented an enhanced recovery after surgery pathway for esophagectomy. In the first year, study investigators were able to reduce overall complications, specifically atrial arrhythmias, and postoperative ileus.

[Small intestinal mucormycosis associated with acute myeloid leukemia: a case report].

The patient was a man in his 70s. During the treatment for acute myeloid leukemia, abdominal pain and bloody stools appeared. A diagnosis of small intestinal ileus was made by computed tomography scan. Treatment with an ileus tube did not improve his condition, and enteroscopy revealed the presence of ileal ulcers. Based on histological examination, small intestinal mucormycosis was suspected, and thus, antifungal drugs were administered. However, the patient developed perforated peritonitis and underwent small intestine resection. He was finally diagnosed with small intestinal mucormycosis with the help of the resected specimen. The gastrointestinal form of mucormycosis rarely occurs, and small intestinal lesions are very rare. Enteroscopy was helpful in its diagnosis and treatment.

Recurrent Ileo-ileal Intussusception Caused by Inflammatory Fibroid Polyp: A Rare Case Report.

An inflammatory fibroid polyp is a rare benign lesion of the gastrointestinal tract, which can cause obstruction or intussusception when it reaches a large diameter. We present a case of a 46-year-old female admitted to our clinic with recurrent ileus attacks. We performed segmental resection of the small bowel due to a 3-cm pedunculated polypoid lesion located in the terminal ileum that caused ileo-ileal intussusception and whose pathology was reported as an inflammatory fibroid polyp. In adults presenting with ileus, the possibility of intussusception should be kept in mind.

FORECASTING THE DEVELOPMENT OF PURULENT-INFLAMMATORY POSTOPERATIVE COMPLICATIONS IN PATIENTS WITH OBSTRUCTIVE BOWEL OBSTRUCTION.

OBJECTIVE: The aim: The purpose of the study is to improve the results of treatment of patients with acute intestinal obstruction of tumor origin by developing individualized surgical tactics considering the level of cryoglobulins. PATIENTS AND METHODS: Materials and methods: 96 patients with ileus of tumor origin were studied. The mean age of patients was 54.7 ± 5.9 years. 30 patients were diagnosed with colorectal cancer, 35 patients - with sigmoid cancer, 13 patients - with cecum and ascending colon, 11 patients - with transverse colon cancer, and 7 patients with descending colon cancer. Isolation of cryoglobulins from blood serum was performed by the method of A. E. Kalovidoris with modifications. The content of Ig A, Ig M, Ig G, total Ig E in the serum was investigated using enzyme-linked immunosorbent assay systems "Granum-Ukraine", the content of allergen-specific Ig E was investigated using enzyme-linked immunosorbent assay systems produced by "Microgen". RESULTS: Results: As a result of treatment of 96 patients, it was found that the level of development of postoperative purulent complications was significantly influenced by the level of cryoglobulinemia and the volume of surgery (CMU, p <0.05). It was found that in patients with decompensated intestinal obstruction, the initial concentration of cryoglobulins was 16.4% higher than in the group with compensated intestinal obstruction (CMU, p <0,05). CONCLUSION: Conclusions: Determination of cryoglobulinemia on admission of patients with acute obstructive ileus of tumor origin is a simple and effective method for predicting the development of purulent-inflammatory complications in the postoperative period and can influence the choice of treatment tactics.

Allen-Masters syndrome as a cause of status ileus - case report.

INTRODUCTION: Internal hernias are rare and are encountered in a small percentage of cases. The hernia in the broad ligament of uterus (Allen-Masters syndrome) is a unique type of internal hernia which represents only approximately 4% of all internal hernias. CASE REPORT: We present the case of a 39-year-old woman admitted for clinical signs of mechanical bowel obstruction. CT examination revealed a dilated loop of small intestine in the left lower abdomen. The patient underwent laparoscopic surgery with the finding of an incarcerated small bowel loop in the ligamentum latum uteri. Small bowel deliberation and ligament defect suture were performed. CONCLUSION: A defect in the ligamentum latum uteri (Allen-Masters syndrome) is a rare diagnosis, usually discovered as an incidental finding in female patients with ileus. This syndrome may explain the vague problems of many patients whose symptoms include dyspareunia, dysmenorrhea, acute and chronic pelvic pain. Allen-Masters syndrome can be diagnosed and successfully managed by laparoscopic approach.

Inpatient administration of opioids and risk for post-operative ileus in older adults.

OBJECTIVE: Post-operative ileus (POI) is a common and potentially serious complication after surgery. We assessed the incidence and identified predictors of POI in older surgical patients. DESIGN: A retrospective observational study. SETTING: University of California-San Francisco electronic medical record data. PARTICIPANTS: Opioid-naïve, noncancer patients, aged 65 and older, who underwent elective surgery in the period 2017-2019. EXPOSURE: Administration of opioid analgesics per day of hospitalization in opioid naïve patients. MAIN OUTCOMES MEASURE: Incidence of POI and likelihood of developing POI. RESULTS: In the study period, 3 percent of opioid naïve patients developed POI. Patients with POI used on average 197.1 oral morphine equivalents (OMEs) per day of hospitalization compared to 82.5 OME in patients without POI (p = 0.013). Yet, there were not statistically significant differences in post-operative pain scores between patients with and without POI. General surgery (p = 0.0031), length of surgery (p = 0.0031), and hospital length of stay (p < 0.0001) were significant predictors of the risk for developing POI. Adjusted inpatient administration of more than 90 OME per day of hospitalization was associated with a four times greater risk for developing POI (p = 0.016). Developing POI was associated with 6.5 (95 percent confidence interval: 5.2-7.8) additional days of hospitalization among patients who developed POI compared to patients who did not develop POI (p < 0.0001). CONCLUSIONS: Adjusted inpatient administration of more than 90 OME significantly increased the risk for developing POI in opioid-naïve older patients. Developing POI after surgery significantly increased the hospital length of stay. Optimizing inpatient administration of opioids may prevent opioid use-related POI and longer hospitalizations.

Application Effect of Somatostatin Combined with Transnasal Ileus Catheterization in Patients with Acute Intestinal Obstruction and Advanced Gastric Cancer.

Objective: To explore the application of somatostatin combined with nasal plug catheterization in patients with advanced gastric cancer and acute intestinal obstruction. Methods. This study included 94 cases of patients with acute intestinal obstruction and advanced gastric cancer, and according to the length of hospital stay, the patients were randomly divided into two groups: the control group and the study group, with 47 cases in each group. Based on the observations made by the team in the control group given somatostatin combined treatment, we observed two groups of patients with gastrointestinal function, serum index, quality of life, therapeutic effect, and adverse reactions. Results. Abdominal distention, abdominal pain duration, and normal exhaust time were significantly shorter in the study group than in the control group. The study group was higher than the control group in terms of gastrointestinal decompression volume, drainage volume, and abdominal circumference reduction within 24 hours (P < 0.05). After treatment, the levels of CRP, IgA, LPS, and FABP were lower than before, and the levels of CRP, IgA, LPS, and FABP in the former group were much lower than those in the latter group (P < 0.05). Compared with before treatment, the former GIQLI scale score was significantly higher than the latter (P < 0.05). After treatment, the efficiency is much higher than the latter (P < 0.05). After treatment, the former significantly lowers the incidence of postoperative complications of the latter (P < 0.05). Conclusion. For patients with advanced gastric cancer and acute intestinal obstruction, it is safe and feasible to use somatostatin combined with transnasal intestinal obstruction catheterization to restore gastrointestinal function, improve inflammatory response, and promote the improvement of quality of life with high safety and feasibility.

Risk factors for postoperative ileus after robot-assisted radical cystectomy with intracorporeal urinary diversion.

OBJECTIVES: To evaluate the risk factors for postoperative ileus in patients who underwent robot-assisted radical cystectomy with intracorporeal urinary diversion. METHODS: We retrospectively analyzed 78 patients with bladder cancer who underwent robot-assisted radical cystectomy with intracorporeal urinary diversion at Fujita Health University between 2011 and 2021. Baseline characteristics and perioperative outcomes were compared between the cohorts with and without ileus. Logistic regression analysis was used to identify the risk factors for postoperative ileus. RESULTS: Out of the 78 patients included in this study, 20 (25.6%) developed postoperative ileus. The ileus cohort was associated with a significantly lower Geriatric-8 score (P = 0.003) and a higher rate of previous abdominal/pelvic surgery (P = 0.04) compared with those of the nonileus cohort. Significantly longer intestinal tract reconstruction time, hospital stay, time to mobilization, fluid intake, solid intake, flatus, and stool were observed in the ileus cohort. According to the results of the logistic regression analysis, the Geriatric-8 sum (P = 0.009), time to mobilization (P = 0.03), and time to fluid intake (P = 0.004) were independent predictors of postoperative ileus. In the model predicting postoperative ileus, the area under the receiver operating characteristic curve was 0.716, and the cutoff value of the Geriatric-8 sum was 13. CONCLUSIONS: Early mobilization and fluid intake and low Geriatric-8 scores were significant risk factors for postoperative ileus. Preoperative Geriatric-8 evaluation is a useful tool for predicting postoperative ileus. Comprehensive enhanced recovery after surgery, including key components, may help bowel recovery and prevent subsequent ileus.

Gallstone Ileus. What therapeutic options are there?

Gallstone ileus is a rare disorder in emergency surgical practice with diagnosis usually difficult and only achieved at surgery. The current approaches are: enterolithotomy, cholecystectomy and fistula repair (one-stage surgery), enterolithotomy with cholecystectomy performed later (two-stage surgery) and only enterolithotomy (most reported surgical procedure). METHODS: The clinical, operative and follow-up data on 14 consecutive patients treated in our clinic for gallstone ileus was retrospectively reviewed. RESULTS: Gallstone ileus was recorded in 0.06% of all operations for biliary lithiasis and 1% of all enteric occlusions. There were 11 women and one men, with a mean age of 77.3 (range 67-100) years. There was a mean delay of 3.16 days for onset of symptoms to admission. Urgent laparotomy confirmed gallstone obstruction and a cholecysto-duodenal fistula (13 cases) or cholecysto-colonic fistula (1 case). We performed one stage surgery in 4 cases, enterolithotomy alone in 8 cases (one case operated initially in another surgical service), Hartman procedure, cholecystectomy and fistula repair in one case and a spontaneous evacuation of the gallstone with cholecystectomy and fistula repair later in another case. We recorded 2 deaths in patients with multiple comorbidities in which only enterolithotomy was performed and with 1 and 2 reinterventions, respectively. Postoperative stay was 9.4 days for cases with simple enterolithotomy and 18.6 days for cases with radical treatment. We did not record any recurrence. CONCLUSIONS: Although rarely encountered in surgical practice, gallstones ileus should be noted in the differential diagnosis of intestinal obstruction in patients with a past history of biliary disease, occlusive syndrome, pneumobilia and possibly ectopic gallstone. The one-stage procedure should be the offered to stabilized patients, but in cases with associated comorbidities, only enterolithotomy represent a best option. KEY WORDS: Gallstone ileus, Cholecystoduodenal fistula, Intestinal Obstruction.

Gallstone ileus in a 100-year-old patient.

We present a case of a 100-year-old polymorbid patient with signs of bowel obstruction. After failure of conservative therapy computed tomography was performed, which revealed the course of the obstruction to be a gallstone in the terminal ileum. The gallstone was removed surgically without complications and the patient recovered well and had an uneventful postoperative course.

Sex Comparisons in Opioid Use and Pain After Colorectal Surgery Using Enhanced Recovery Protocols.

BACKGROUND: Differences in nociception and use of opioids between sexes are of particular interest, considering higher rates of persistent opioid use among women after surgery. Although enhanced recovery protocols (ERPs) have improved postoperative pain control in colorectal surgery, sex-based comparisons of inpatient opioid use after surgery in an ERP remain understudied. METHODS: This retrospective study analyzed data from adults after colorectal surgery using an ERP at a single hospital between 2015 and 2017. The main outcome was the rate of opioid consumption measured as oral morphine equivalents per inpatient day. Poisson regression determined association between sex and opioid consumption, accounting for early discharge, using inverse probability weighting and adjusting for covariates that retained significance on univariate analysis. Linear regression assessed the association between sex and pain scores on postoperative days 0-5 adjusting for covariates. RESULTS: Of 588 patients included, 43% were men and 57% were women. In the unadjusted model, malignancy, prehospital psychiatric medication and analgesic use, tobacco, ileostomy creation, operative time, and postoperative complications were associated with increased opioid consumption. In multivariate analyses, prehospital opioid and nonopioid analgesic use, operative time, anastomotic leak, and postoperative ileus remained significantly associated with increased inpatient opioid consumption. However, there was no significant association between sex and opioid use in crude or adjusted analysis (incidence rate ratio: 1.09; 95% confidence interval: 0.90, 1.32). Women reported higher average daily pain scores (coefficient: 0.29; 95% confidence interval: 0.04, 0.55) in adjusted analyses. CONCLUSIONS: Among patients undergoing colorectal surgery using an ERP, sex-based differences exist in pain scores but not early postoperative opioid consumption. Identification of intragroup differences in postoperative pain and opioid use among patients managed with an ERP serves as targets for customization and enhancement of current protocols. Furthermore, incongruence between reported pain and analgesic administration may have important implications for sex-related differences in persistent opioid use.

[Gallstone ileus as a cause of abdominal pain in the elderly patient]. / Íleo biliar como causa de dolor abdominal en el paciente anciano.

Gallstone ileus is a rare and potentially serious complication of cholelithiasis. It is defined as a mechanical intestinal obstruction secondary to the presence of a gallstone in the intestinal luz. The most frequent cause is impaction of the calculus in the ileum after passing through a bilioenteric fístula. It has a high morbidity and mortality rate, mainly due to the difficulty and delay in its diagnosis. A retrospective study is presented of 4 cases of gallstone ileus treated between 2013 and 2017 in the Hospital Nuestra Señora del Prado. An analysis was performed on the clinical characteristics, diagnostic tests, and surgical treatment.

Diagnostic conundrum: simultaneous gallstone ileus and a gas-filled inguinal hernia in a patient with lower abdominal pain.

Gallstone ileus and small bowel diverticulosis are uncommon pathologies. However, the simultaneous presentation of both in this patient provided a diagnostic puzzle for the surgical and radiological teams at our institution. The imaging also demonstrated several typical features for the pathologies in question. Ultimately the management of the patient was not compromised by the diagnostic dilemma, but the imaging findings represent a useful learning opportunity for all radiologists and general surgeons.

Rectus sheath haematoma causing ureteric obstruction.

Rectus sheath haematoma is an uncommon condition. However, its incidence is increasing, attributed to greater use of anticoagulant therapy. We present the case of an 83-year-old woman on therapeutic enoxaparin for a prior pulmonary embolus who underwent elective right hemicolectomy and developed a rectus sheath haematoma 13 days postoperatively. Her extensive haematoma compressed retroperitoneal structures including the right ureter. She was successfully managed conservatively.

Takotsubo cardiomyopathy in a patient with ileus: a case report.

BACKGROUND: Takotsubo cardiomyopathy (TCM) is a form of stress-induced cardiomyopathy featured by the dilatation of the apex of the left ventricle during systole. Whereas the pathogenesis of this disorder is not well understood, it usually occurs after an emotional or physical stress such as acute asthma, surgery, chemotherapy, and stroke. However, its occurrence in ileus patients is rarely reported. We hereby report probably the first case of TCM after ileus in the literature and discuss its implications. CASE PRESENTATION: An 85-year-old man was brought to the Emergency Department due to vomiting, abdominal pain, and no stool passages for 2 days. His abdomen was markedly distended, and ileus pattern was observed in the plain film of abdomen. Electrocardiogram showed right axis deviation, poor R-wave progression, and diffuse ST-segment elevation in the anterior leads, and cardiomegaly was observed by roentgenogram. A ventriculography showed an ejection fraction of 33% and confirmed the apical dilation consistent with TCM. He was treated with medication and discharged without remarkable adverse events. A follow-up transthoracic echocardiogram 4 months later showed normalization of his left ventricular systolic functions. CONCLUSION: The precise mechanisms of the development of TCM are still unknown, but it is widely believed that it is triggered by the catecholamine surge produced in response to stress. This case demonstrated that such a stress can be of various forms, including ileus and other conditions that may lead to severe abdominal pain, and highlight the importance of awareness in diagnosing this rare but potentially lethal condition.
