Grip strength predicts postoperative ileus among patients undergoing abdominal minimally invasive surgery: a prospective multicenter cohort study.

Postoperative ileus (POI) is a prevalent complication following abdominal surgery, leading to extended hospitalization and escalated medical expenses. Few studies have investigated the association between grip strength and POI after abdominal minimally invasive surgery (MIS). A prospective multicenter cohort study was conducted using data from a prospectively registered database of patients undergoing abdominal MIS from March to December 2022. Grip strength levels were categorized and analyzed for their association with POI using multiple regression analysis with demographic adjustments. A smooth curve was generated to visualize the linear relationship. Out of 501 eligible patients, 393 were analyzed, with 67 (17.05%) developing POI. Grip strength was significantly and independently associated with POI, with each 1kg and 8.57kg (SD) increase in grip strength resulting in ORs of 0.94 and 0.61, respectively. Grip strength categories specific to sex and age were significantly associated with POI incidence, with individuals in the high grip strength group having a lower risk. Subgroup analysis showed grip strength as a significant predictor of POI risk, especially for males and older individuals. Higher grip strength was associated with a significantly lower risk of POI in males (OR = 0.29, 95% CI 0.09-0.90, p = 0.031) and older adults over 60years old (OR = 0.31, 95% CI 0.10-0.98, p = 0.046). Grip strength can predict the occurrence of POI in patients undergoing abdominal MIS. This can help identify high-risk individuals and improve perioperative management for better outcomes.

Small bowel obstruction

Small bowel obstruction is a common and serious condition that nurses often encounter, making up 80% of bowel obstructions in the US. It frequently occurs in older adults and those who've had abdominal surgeries, with many cases requiring surgical intervention, especially for complete obstructions.

An unusual case of small-bowel obstruction: Broad ligament hernia.

Broad ligament hernias (BLHs) are rare internal hernias that can lead to serious complications if left untreated. In this case report, we present the case of a BLH in a female patient and discuss its clinical presentation, diagnosis and management. A 40-year-old woman presented with subacute intestinal obstruction symptoms, including the inability to pass flatus and faeces and recurrent bilious vomiting. A computed tomography (CT) scan confirmed small-bowel obstruction adjacent to the uterus within the left broad ligament. Diagnostic laparoscopy revealed a loop of obstructed small intestine within the broad ligament, which was released and found to be healthy. The defect between the broad and infundibulopelvic ligaments was closed with sutures. The patient had an uneventful recovery and was asymptomatic at a 6-month follow-up. BLHs can be congenital or acquired, with acquired defects often resulting from previous surgeries or pregnancy-related causes. The clinical presentation typically involves the symptoms of bowel obstruction, and a CT scan is the diagnostic modality of choice, showing characteristic findings such as closed-loop obstruction and bowel dilation. Laparoscopic management offers the advantages of faster recovery and less morbidity. Closure of the defect using nonabsorbable sutures is the standard surgical approach, although a wide opening of the defect has also been described. Recurrence is a possibility, particularly if absorbable sutures are used for closure. This case report highlights the importance of early diagnosis and intervention in BLHs to prevent the complications and emphasises the role of laparoscopy in their management.

Laparoscopic Management of Acute Small Bowel Obstruction: A Retrospective Study at a Tertiary Center in the United Kingdom.

Objectives To present a single-center experience of laparoscopic management of acute small bowel obstruction (ASBO) based on seven years of data and demonstrate its suitability for the United Kingdom (UK). Methods A retrospective review of case notes to evaluate postoperative outcomes was conducted. All emergency small bowel obstructions treated laparoscopically were included. The cases that were converted to a laparotomy were excluded. Demographics (age, sex), American Society of Anesthesiologists (ASA) grade, indication for surgery, duration of stay, complications, requirement of stoma, requirement of intensive treatment unit/high dependency unit (ITU/HDU), reoperation/readmissions, and 30-day mortality were noted. The results were tabulated and analyzed accordingly. Results There were 119 patients studied, with a median age of 66 (range: 17-97). The sex ratio was 62 females to 57 males. Primary etiologies of adhesion bands (49.5%, 59) and hernia (31.9%, 38) werethe most common. Minor and majorcomplications were 15 (12.6%) and 37 (31%),respectively. Three (2.5%) patients passed away within 30 days of surgery. The medianlength of stay (LOS) was eight days. ThemedianLOS subgroup analysis showed nine days for adhesiolysis and six days for hernias. Discussion This study shows that there is significant heterogeneity in outcomes regarding small bowel obstruction around the world. We have demonstrated similar to better results in our center relative to other prominent centers in the UK. This can be attributed to the patient cohort, presentation, and physiological status on admission, delay to surgery, and associated co-morbidities to name a few. Conclusion This study indicates that laparoscopic surgery is a safe approach to treating ASBO, provided adequate expertise and infrastructure are available.

Machine Learning Approaches for the Prediction of Postoperative Major Complications in Patients Undergoing Surgery for Bowel Obstruction.

Performing emergency surgery for bowel obstruction continues to place a significant strain on the healthcare system. Conventional assessment methods for outcomes in bowel obstruction cases often concentrate on isolated factors, and the evaluation of results for individuals with bowel obstruction remains poorly studied. This study aimed to examine the risk factors associated with major postoperative complications. We retrospectively analyzed 99 patients undergoing surgery from 2015 to 2022. We divided the patients into two groups: (1) benign-related obstruction (n = 68) and (2) cancer-related obstruction (n = 31). We used logistic regression, KNN, and XGBOOST. We calculated the receiver operating characteristic curve and accuracy of the model. Colon obstructions were more frequent in the cancer group (p = 0.005). Operative time, intestinal resection, and stoma were significantly more frequent in the cancer group. Major complications were at 41% for the cancer group vs. 20% in the benign group (p = 0.03). Uni- and multivariate analysis showed that the significant risk factors for major complications were cancer-related obstruction and CRP. The best model was KNN, with an accuracy of 0.82. Colonic obstruction is associated with tumor-related blockage. Malignant cancer and an increase in C-reactive protein (CRP) are significant risk factors for patients who have undergone emergency surgery due to major complications. KNN could improve the process of counseling and the perioperative management of patients with intestinal obstruction in emergency settings.

Association of intra-operative red blood cell transfusion on the systemic immune index and recovery in patients undergoing cesarean section: a large propensity score-matched study.

Post-partum hemorrhage (PPH) is a leading cause of maternal death worldwide. However, the effect of blood transfusion in patients undergoing cesarean section remains unclear. The analysis was based on the retrospective evaluation of the pre- and post-operative data for 1231 patients who underwent a cesarean section at our hospital between January 2016 and June 2020. Patients were classified into the blood transfusion group (BT) and the no blood transfusion group (NBT) based on their intra-operative blood transfusion status. After propensity score matching, 322 patients were included in both groups and between-group differences in length of hospital stay (LOS), perioperative systemic inflammation indicators, and post-operative complications were evaluated. The LOS was longer in the BT (median, 6.6days) than the NBT (median, 4.2days) group (P = 0.026). The post-operative complication rate was higher for the BT than NBT group, as follows: vomiting, 3.2% vs. 4.9%, P = 0.032; fever, 5.41% vs. 2.24%, P = 0.032; wound complications, 15.44% vs. 10.45%, P = 0.028; and intestinal obstructions, 5.88% vs. 2.75%, P = 0.034. Systemic inflammation indicators increased significantly, from the pre-operative baseline, for both groups at post-operative day (POD) 1 and POD3. On multivariate analysis, intra-operative blood transfusion was associated with a longer LOS (hazard ratio, 1.52; 95% confidence interval, 1.07-2.25). Intraoperative blood transfusion for cesarean section was associated with increased levels of systemic inflammation indicators, higher post-operative complication rates, and prolonged hospital stay.

Acute abdomen: an atypical presentation of acquired hemophilia

Acquired hemophilia is a rare but potentially life-threatening disorder characterized by the development of acquired hemophilia A, leading to bleeding complications. Spontaneous, mild-to-life-threatening bleeding in typically elderly individuals without a personal or family history of bleeding is the hallmark of acquired hemophilia A (AHA), a rare autoimmune bleeding illness caused by the formation of auto-antibodies against endogenous factor VIII (FVIII). This hallmark represents our present case, with no obvious history related to the bleeding issue. Prompt detection and treatment of bleeding are essential for the best outcomes. We present a case of a 66-year-old male who had acute-onset severe abdominal pain and with constipation for five days, associated with nausea and loss of appetite. On physical examination, the patient appeared pale, and abdominal examination revealed diffuse tenderness with guarding. Initial evaluation revealed tachycardia and hypotension. Initial abdomen X-rays revealed features suggestive of small bowel obstruction. The patient was stabilized with intravenous fluids, referred to a surgical team, and admitted to the acute bed in the general ward for further management.

Chilaiditi Syndrome: An Incidental Finding on a Chest Radiograph in a Long-Term Ventilated Patient

Background: Chilaiditi syndrome is a situation with a structural impingement of the colon on the liver, leading to an elevated hemidiaphragm in the X-ray along with a gas-like ap-pearance in the right hemithorax. It is generally a benign disease that is managed conservatively upon diagnosis. Rarely, it can be a cause of intestinal obstruction. Chilaiditi syndrome was origi-nally named after Demetrius Chilaiditi, the Greek radiologist who first described the case in 1910 while working in Vienna. Case Presentation: Here, we have described the case of a 76-year-old male who was admitted to our long-term care facility for chronic respiratory failure, and he was connected to mechanical ventilation via tracheostomy. He was having occasional bouts of constipation, and was on regular laxatives. In a CT chest film done because of very thick respiratory secretions and desaturation, an incidental finding of Chilaiditi syndrome was noted. : The patient has been managed conservatively with laxatives and per-need enemas. : Chilaiditi syndrome is a rare condition in which the colon interposes between the liver, right hemidiaphragm, and the abdominal wall, causing occasional clinical symptoms. Conversely, radiographic findings without clinical symptoms are known to exhibit the Chilaiditi sign. The disease's prevalence is estimated to be somewhere between 0.025 and 0.28%. Conclusion: Chilaiditi syndrome is a syndrome that refers to the interposition of the colon upon the hepatic flexure. It is a very rare but a serious cause of constipation, resulting in severe symptoms to the extent that they may warrant surgical intervention.

Complications of deep infiltrative endometriosis of gastrointestinal tract

Objective. To summarize the literature data on the main complications of deep infiltrative endometriosis, including ileocecal. Endometriosis is a complex disease that can begin to develop from birth. Despite all the already existing theories of the origin and development of this disease, further large-scale studies are required to investigate the etiology, pathogenesis, and phenotypes of this nosology and its relationship with pain and infertility. External genital endometriosis often affects various parts of the gastrointestinal tract. The rectosigmoid junction of the colon is most commonly affected (81.3%), followed by the appendix (6.4%), small intestine (4.7%), dome of the cecum (4.1%), and other parts of the gastrointestinal tract (1.7%). In recent years, interest in ileocecal endometriosis and its timely diagnosis and treatment has begun to grow among practicing specialists. Presently, deep infiltrative endometriosis is widely studied by obstetricians–gynecologists and by related specialists, such as general surgeons, coloproctologists, and gastroenterologists, in connection with extragenital lesions leading to severe complications. Cases of intestinal perforation caused by deep infiltrative endometriosis, bleeding, and small intestinal obstruction have been described.

Integrated enhanced recovery after surgery protocol in radical cystectomy for bladder tumour-A retroprospective study.

Enhanced recovery after surgery (ERAS) is a patient-centerd, evidence-based approach to improve postoperative outcomes. The protocol involves multidisciplinary collaboration and standardisation of perioperative interventions. ERAS has shown positive results in reducing hospitalisation and complications. The study conducted in the Department of Urology was a retro-prospective study. It included an ERAS cohort group of 47 patients, studied prospectively from May 2021 to May 2023. These patients were compared to a historical cohort of 47 consecutive patients who underwent radical cystectomy with traditional care before the ERAS pathway was implemented. The primary outcome was hospital length of stay (LOS). Secondary outcomes included perioperative management, time to recovery milestones and complications. Implementation of ERAS pathway for radical cystectomy was associated with reduced hospital LOS (mean LOS 16.19 ± 2.53 days vs. 10.26 ± 3.33 days 7 days; p< 0.0001), reduced time to key recovery milestones, including days to first flatus (3.17 vs. 2.68; p= 0.013) and days to first solid food (5.19 vs. 3.45 p value < 0.0001), first stool (5.53 vs. 4.23; p< 0.0001), reductions in some complications like postoperative ileus (p value = 0.021) and need for total parental nutrition (p value = 0.023). In conclusion, the implementation of the integrated approach facilitates a more efficient recovery process, potentially reducing healthcare costs and enhancing patient comfort.

Seprafilm® and adhesive small bowel obstruction in colorectal/abdominal surgery: an updated systematic review

BackgroundThe efficacy of Seprafilm® in preventing clinically significant adhesive small bowel obstruction (ASBO) is controversial and deserves further review. The aim of this review was to assess the utility of Seprafilm® in preventing clinically significant adhesive bowel obstruction after abdominal operations, with separate focus on colorectal resections. The secondary aim was to provide an updated literature review on the safety profile of this implant.MethodsAn up-to-date systematic review was performed on the available literature between 2000 and 2023 on PubMed, EMBASE, Medline, and Cochrane Library databases. The main outcome measures were rates of adhesive bowel obstruction, as well as rates of intervention. The secondary outcome was the clinical safety profile of Seprafilm® as described in current literature.ResultsA total of 17 observational studies were included, accounting for 62,886 patients. Use of Seprafilm® was associated with a significant reduction in adhesive bowel obstruction events (OR 0.449, 95% CI: 0.3271 to 0.6122, p < 0.001), with preserved efficacy seen in laparoscopic cases. This did not translate into a reduced rate of reintervention. Clinicians should also be aware of isolated reports of a paradoxical inflammatory reaction leading to fluid collections after Seprafilm® use, although they appear uncommon.ConclusionSeprafilm® can be considered in select patients although further study to determine which patients will benefit most is required.

6701 Bilateral Adrenal Hematomas As Initial Presenting Sign Of Lung Adenocarcinoma

Abstract Disclosure: S. Gumireddy: None. R. Panta: None. Y. Shaikh: None. Introduction: Lung cancer typically presents with dyspnea, chest pain, hemoptysis, weight loss, or recurrent pulmonary infections. This case illustrates primary lung adenocarcinoma presenting with abdominal pain and bilateral adrenal hematomas. Clinical Case: 51-year-old male presented to the emergency department with left sided abdominal pain persisting for one week. CT abdomen showed a left suprarenal mass measuring 4.5 x 5 x 4.3cm indicating an acute adrenal hematoma. An MRI showed a partially solid left adrenal lesion that had hemorrhaged and a 1.3cm hemorrhagic nodule in the right adrenal gland. The patient remained hemodynamically stable. Hormonal evaluation done while patient was in the hospital showed renin level 0.417ng/mL/hr, aldosterone level &amp;lt;1.0ng/dL, epinephrine level 312pg/mL, norepinephrine level 333pg/mL, cortisol 11.3, ACTH level 13, plasma metanephrine levels 93pg/mL, plasma normetanephrine levels 111.7pg/mL, DHEA-S 151mcg/dL, potassium 4.1mmol/L, raising concern for hypersecretion. Patient was discharged with plans for outpatient follow-up but was readmitted in two months due to worsening abdominal pain. Repeat imaging revealed an increase in size of adrenal lesions, measuring 3.3 x 3.6 cm within the right adrenal gland and a 6.7 x 6.3 cm heterogeneously enhancing lesion within the left adrenal gland concerning for metastatic disease to bilateral adrenals and to the ileum causing small bowel obstruction. Chest imaging showed a 2.2cm irregular right apical nodule. Subsequent hormonal evaluation showed normalization of plasma metanephrine levels at 15.8pg/mL, renin level 3.314ng/mL/hr, aldosterone level 4.3ng/dL, deoxycorticosterone level 4.8ng/dL, androstenedione level 40ng/dL, plasma normetanephrines 146.4pg/mL. The patient underwent left adrenal gland mass biopsy which showed metastatic poorly differentiated adenocarcinoma of pulmonary origin. Tumor cells were positive for keratin cocktail, TTF1 and synaptophysin supporting the morphologic interpretation. Patient is currently receiving treatment with carboplatin, pemetrexed, and pembrolizumab. Conclusion: Adrenal masses can be unilateral (85%) or bilateral (15%). While most unilateral adrenal masses are benign and nonfunctional, bilateral adrenal masses are likely to be metastatic disease, hemorrhage, infiltrative disease, congenital adrenal hyperplasia, macronodular Cushing’s syndrome, or bilateral cortical adenomas. Although uncommon, our case highlights the importance of considering metastatic disease to the adrenal glands as a potential initial manifestation of primary cancers. The most likely primary cancers to metastasize to the adrenal glands are breast, lung, colon, kidney, and esophagus. Presentation: 6/1/2024

Evaluation of the da Vinci single-port system in colorectal cancer surgery: a scoping review.

Minimally invasive surgery for the treatment of colon and rectal cancer has gained popularity due to its association with reduced postoperative pain, shorter hospital stays, and quicker recovery. The Da Vinci Single-Port (SP) System combines single-port laparoscopy with robotic assistance. This scoping review aims to evaluate the safety and short-term postoperative outcomes of utilizing the Da Vinci SP platform in colorectal cancer surgery. A scoping review was conducted adhering to the PRISMA-ScR guidelines. Data were collected from PubMed, Embase, and the Web of Science Library as of December 22, 2023. Studies were screened and selected based on predefined criteria, focusing on the application of the SP robotic system in colorectal procedures. Data extraction included demographics, surgical details, intraoperative and postoperative outcomes. A narrative summary of the results was provided due to the heterogeneity in study designs. From an initial 2312 articles, 22 studies were selected for analysis, encompassing 465 patients undergoing robotic SP colorectal surgeries. Of these, 384 (82.6%) had a cancer diagnosis. The median age was 65years, with approximately 60% being male. The median operative time was 225min, with docking times averaging 12-20min. Conversion to multi-port laparoscopy occurred in 4.2% of cases, with no conversions to open surgery. Mean intraoperative blood loss ranged from 50 to 150ml. The mean number of lymph nodes retrieved ranged from 15 to 28. A diverting ileostomy was constructed in 20.3% of patients. Median times to flatus and soft diet were 2.5 and 3days, respectively, with hospital stays ranging from 3 to 11days. Perioperative complications occurred in 15.1% of patients, including wound infections (5.1%), anastomotic leakage (3.7%), and postoperative ileus (2.8%). Negative margin status (R0 resection) was achieved in 95% of cases. The Da Vinci SP robotic platform demonstrates promising safety and effectiveness in colorectal cancer surgery. It achieves high rates of successful oncological resection, adequate lymph node retrieval, and minimal intraoperative blood loss. Postoperative outcomes indicate quicker recovery times and manageable complication rates. However, longer follow-up studies are necessary to fully assess recurrence rates and long-term survival benefits associated with this innovative surgical approach.

7783 Pheochromocytoma Unusually Presenting As Intestinal Pseudo-Obstruction: A Case Report

Abstract Disclosure: J.V. Chua: None. E.C. Cunanan: None. J.G. Sazon: None. J.L. Reyes: None. Introduction: Pheochromocytoma is a rare neuroendocrine tumor that arises from the adrenal medulla. It may present with a variety of symptoms that can resemble other diseases as a result of the effects of catecholamine overproduction on the different organ systems of the body, occasionally making diagnosis difficult and delaying appropriate treatment.Intestinal pseudo-obstruction is an unusual presentation of pheochromocytoma from the effects of excessive catecholamines on the gastrointestinal system, resulting in decreased peristalsis with constriction of the sphincter muscles, consequently prolonging intestinal transit time. Currently, there is no available data on its incidence or prevalence rate. Clinical Case: This is a case of a 50-year-old Filipino male initially presenting with abdominal pain and enlargement with inability to pass stool and flatus, not relieved by laxatives, enemas, and nasogastric and rectal tube decompression. Abdominal radiograph revealed segmental ileus versus partial large bowel obstruction, while abdominal CT scan showed fecal impaction and an incidental finding of an enhancing adrenal mass on the left adrenal gland. Colonoscopy findings were unremarkable. Laboratory workup demonstrated elevated 24-hour urine metanephrine levels with a value of 44.62 mg/24 hours (normal value: 0-1.0 mg/24 hours). The patient was initially managed conservatively, but no improvement in symptoms was noted. Pre-operative preparation was done with terazosin and intravenous saline infusion, and the patient then underwent left open adrenalectomy with bowel decompression, which provided resolution of symptoms and resumption of regular bowel movement post-operatively. The final result of the histopathologic examination confirmed the diagnosis of pheochromocytoma. Conclusion: Gastrointestinal symptoms such as ileus and pseudo-intestinal obstruction are uncommon presentations of pheochromocytoma. A high index of suspicion is necessary among patients presenting with these symptoms, and pheochromocytoma should be considered as part of the differential diagnosis. Presentation: 6/1/2024

Treatment Strategies for Sigmoid Volvulus : A case series of 15 patients

Sigmoid volvulus, a condition characterized by the twisting of the sigmoid colon, is a frequent cause of large bowel obstruction. This study aims to review and evaluate the treatment strategies applied to 15 patients diagnosed with sigmoid volvulus at our institution. The outcomes, complications, and long-term results were analyzed to identify the most effective management approaches. The treatment modalities ranged from conservative management to surgical interventions. Our findings indicate that a multidisciplinary approach, timely intervention, and appropriate patient selection are key determinants of successful outcomes.

Tubeless ureteroenteric anastomosis in robot-assisted radical cystectomy with intracorporeal urinary diversion does not increase the risk of anastomotic stenosis or postoperative complications.

The objective is to demonstrate that omitting ureteral stent placement in robotic intracorporeal urinary diversion does not lead to increased risk of perioperative complications, namely ureteral strictures or anastomotic leaks. We retrospectively reviewed the records of 68 consecutive patients who underwent robotic radical cystectomy with ileal conduit creation or orthotopic neobladder by a single surgeon between January 2020 and September 2023. Chronologically, the first cohort of patients had ureteral stents placed to bridge the ureteroenteric anastomosis, and in the second cohort, stenting was omitted. Cohort 1 consisted of 28 patients with surgeries performed between January 2020 and April 2021, while cohort 2 had 40 patients who underwent surgery from April 2021 to September 2023. The cohorts were well matched with regard to patient age, gender, ASA score and rate of neoadjuvant chemotherapy. The choice of urinary diversion was left to surgeon and patient preference, and there was no significant difference in the proportion of ileal conduits versus orthotopic neobladders within each cohort. Estimated blood loss, total operative time, inpatient length of stay and pathologic T and N staging did not statistically differ between the cohorts. Overall, there was no difference in the rates of postoperative ileus, ureteral stricture, anastomotic leak, infectious complications, and 30-day readmission rates between the groups. Tubeless ureteroenteric anastomosis in patients undergoing robotic radical cystectomy with intracorporeal diversion does not appear to increase the risk of anastomotic strictures or postoperative complications. Further prospective evaluation is warranted.
