I Dear Editor i , We present the case of a 55-year-old woman with a rectal polyp in the site of a scar from polypectomy surgery performed 1 year previously. When performing TAMIS for anterior rectal lesions, the prone position facilitates easier closure of the defect, avoids bowel injury and maintains pneumorectum. The patient underwent transanal minimally invasive surgery (TAMIS) using the GelPOINT platform with AirSeal to maintain pneumorectum. [Extracted from the article]

Background: Ulcerative colitis (UC) is a chronic mucosal inflammatory bowel disease of the colon and rectum. After 10 years of having the disease, there is a significant risk of dysplasia or cancer in the affected colon and rectum, and because of the often aggressive biology of these tumors, frequent endoscopic surveillance is warranted. Over a third of patients with UC will ultimately require an operation, and although for specific cases alternative operations can be pursued, most patients prefer an ileal pouch-anal anastomosis (IPAA) with J-pouch construction. Case: A staged IPAA removes the affected colon and rectum treating UC and also restores intestinal continuity. However, the standard colectomy for UC includes low ligations of the main colonic vascular pedicle branches (ileocolic, right colic, middle colic and inferior mesenteric) that does not address a proper oncologic operation. A high ligation of the named vessels as well as a proper resection of the affected colon with its mesentery and lymph node package are needed to treat colon cancer. Analogous to a total mesorectal exicision for rectal cancer, a more radical procedure to remove the tumor and lymph node packet for colon cancer is described as a complete mesocolic exision (CME) in efforts to increase disease free survival. Discussion: We demonstrate a laparoscopic subtotal colectomy for UC, with an oncologic complete mesocolic excision for a left transverse colon carcinoma in the setting of chronic mucosal inflammation secondary to chronic UC as the first procedure in a 3-staged IPAA. In the video, it is also demonstrated how the lymph node dissection is extended towards the greater gastric curvature and comprising omentum and gastrocolic ligament. There were no postoperative complications in the 44-year old male patient. [ABSTRACT FROM AUTHOR]

- Abstract
Crohn’s disease is a chronic inflammatory ailment that can affect the colon andor small intestine. A genetic basis for disease distribution is being sought, although the available data are seminal. The STAT5gene is known to influence colonic permeability, mucosal regeneration, and interleukin 2 production, although its role in the distribution of Crohn’s disease is unclear.

- Abstract
Surgeons regularly educate patients on health promoting behaviours including diet, sleep and exercise. No study thus far has explored surgeons’ personal compliance with these health behaviours and their relationship with surgical performance. The primary outcomes of this study were self-reported health, health related behaviours, wellbeing, fatigue and surgical performance.

Minimum rest is mandated in high stake industries such as aviation. The current system of healthcare provision permits on-call surgeons to work in sleep deprived states when performing procedures. Fatigue has been demonstrated to negatively affect performance. This study aimed to explore measurements of sleep deprivation and their impact on simulated performance. This was a single site study conducted between September 2019 and February 2020. Surgical trainee and consultants were conveniently sampled from a single site. All testing was done between 7 AM and 9 AM. Participants completed electroencephalogram testing using a modified Multiple Sleep Latency Test testing for objective sleep measurement, the Pittsburgh Sleep Quality Index, Chalder Fatigue Scale and Epworth Sleepiness Scale for subjective sleep measurement. The Psychomotor Vigilance Task and the SIMENDO simulated tasks were used for standardized performance assessment. Surgeons entered sleep in 6 min, on average pre-call. This significantly decreased to an average of 164 s post-call (P = 0.016). Pittsburgh Sleep Quality Index scoring was 5, indicating poor baseline sleep quality. There was higher self-reported fatigue and sleepiness in post-call states. Performance decrements were noted in cognitive performance reaction time and aspects of technical instrument proficiency. Surgeons are objectively sleep deprived pre-call according to internationally recognized guidelines. This sleep deprivation increases significantly in post-call states. Tasks with higher cognitive demands showed greater levels of diminished performance compared to those with lower cognitive demands. Current models of provision of surgical on-call are not conducive to optimizing sleep in surgeons. Prioritization of workload in post-call states, focusing on preserving individuals cognitive resources and utilizing lower cognitively demanding aspects of work is likely to have positive impacts on performance outcomes.

COLON cancer , *LAPAROSCOPY , *LAPAROSCOPIC surgery , *LENGTH of stay in hospitals , *PROGRESSION-free survival - Abstract
Background: The laparoscopic approach for colon cancer has become widely accepted. However, its safety for T4 tumors, and particularly for T4b tumors when local invasion to adjacent structures occurs, remains controversial. This study aimed to compare short and long-term outcomes in patients undergoing laparoscopic vs. open resection for T4a and T4b colon cancers. Methods: A prospectively maintained, single-institution database was queried to identify patients with pathological stage T4a and T4b colon adenocarcinomas electively operated on between 2000 and 2012. Patients were divided into two groups based on the use of laparoscopy. Patient characteristics, perioperative, and oncologic outcomes were compared. Results: One hundred and nineteen patients [41 laparoscopic (L), 78 open surgeries (O)] met the inclusion criteria. No difference was observed in age, gender, BMI, ASA, and procedure between groups. Tumors treated by L were smaller than O (p = 0.003). No difference was observed in morbidity, mortality, reoperation, or readmission between the groups. Length of hospital stay was shorter in L than O (6 vs. 9 days, p = 0.005). Conversion to open was necessary in 22% of all T4 tumors laparoscopic cases. However, when tumors were subdivided by pT4 classification, conversion was necessary for 4 of 34 (12%) pT4a patients vs. 5 of 7 (71%) pT4b patients (p = 0.003). In the pT4b cohort (n = 37), more tumors were treated by the open approach (30 vs. 7). For pT4b tumors, the R0 resection rate was 94% (86% in L vs. 97% in O, p = 0.249). The use of laparoscopy did not impact overall survival, disease-free survival, cancer-specific survival, or tumor recurrence overall in all T4 or T4a and T4b tumors. Conclusions: Laparoscopic surgery can be safely performed in pT4 tumors with similar oncologic outcomes as compared to open surgery. However, for pT4b tumors, the conversion rate is very high. The open approach may be preferable. [ABSTRACT FROM AUTHOR]

The Arctic is warming at a rate nearly twice the global average, leading to thawing permafrost, increased coastal erosion, and enhanced delivery of riverine terrestrially-derived dissolved organic matter (tDOM) to coastal waters. This humic-rich tDOM has the ability to attenuate light required for photosynthesis and stimulate heterotrophic growth by supplying a source of labile organic carbon. Due to tDOM's high carbon to nitrogen (C : N) ratio, additional nitrogen is required for microorganisms to utilize this excess carbon for growth, thus exacerbating competition between autotrophs and heterotrophs for limiting nutrients and potentially reducing primary production. The effect of Arctic tDOM additions on nitrate uptake by two microplankton size fractions in the coastal Chukchi Sea was quantified using 15N tracer methods. To assess the biogeochemical vs. spectral impacts of tDOM, the uptake incubations were amended with either tDOM or light attenuating films that mimic light absorption by the tDOM. Nitrate uptake and primary production rates in the larger, predominantly phytoplankton, size fraction generally decreased with increasing tDOM additions. The change in light attenuation alone accounted for a ∼ 50% reduction in nitrate uptake. Responses in the smaller size fraction varied seasonally with tDOM additions stimulating uptake in spring and suppressing it in summer. The largest variation in summer nitrate uptake can be explained by the shared effect of biogeochemistry and light attenuation. Therefore, large increases in tDOM delivery currently occurring and predicted to increase in the coastal Arctic, could reduce primary production, broadly impact nitrogen and carbon cycling, and affect higher trophic levels.

RECTAL cancer , *COLON cancer , *COLON (Anatomy) , *COLORECTAL cancer , *QUALITY of life - Abstract
Purpose: Colorectal cancer patients are commonly considered a single entity in outcomes studies. This is particularly true for quality of life (QOL) studies. This study aims to compare oncologic and QOL outcomes between right colon, left colon, and rectal cancer in patients operated on in a single high-volume institution. Methods: A prospectively maintained database was queried to identify patients with pathological stages I–III colorectal adenocarcinoma electively operated on with curative intent between 2000 and 2010. Patient characteristics, perioperative and oncologic outcomes, and QOL were compared according to cancer location. Results: Two-thousand sixty-five (606 right colon cancer [RCC], 366 left colon cancer [LCC], and 1093 rectal cancer [RC]) patients met the inclusion criteria. LCC had better overall survival (OS) and disease-free survival (DFS) in the non-adjusted analysis (p < 0.001) and better OS in multivariate analysis adjusted by age, gender, ASA, chemotherapy, and pathological stage (p = 0.024). Although RCC had worse OS and DFS in non-adjusted survival analysis than LCC and RC, when adjusted for the factors above, RCC had better survival outcomes than RC, but not LCC. COX regression analysis showed age (p < 0.001), gender (p = 0.016), ASA (p < 0.001), pathological stage (p < 0.001), adjuvant chemotherapy (p = 0.043), and cancer location (p = 0.024) were independently associated with OS. Age (p < 0.001), gender (p = 0.030), ASA (p = 0.004), and pathological stage (p < 0.001) were independently associated with DFS. Patients with RC reported more sexual dysfunction and work restrictions than colon cancers (p = 0.015 and p < 0.001, respectively). Conclusion: In an adjusted multivariate analysis, colon cancers demonstrated better survival outcomes when compared to rectal cancers. [ABSTRACT FROM AUTHOR]

DIVERTICULITIS , *DIVERTICULOSIS , *FAMILY history (Medicine) , *IMMUNE response , *TRANSCRIPTOMES - Abstract
Background: The management of diverticulitis is compromised by difficulty in identifying patients who require surgery for recurrent or persistent disease. Here, we introduce the concept of multifocal diverticulitis (MFD), characterized by multiple episodes of diverticulitis occurring at different locations within the colon.Aims: To compare clinical characteristics, success of surgical management, and colonic transcriptomes of MFD patients to patients with conventional unifocal diverticulitis (UFD).Methods: This retrospective study included 404 patients with CT-confirmed diverticulitis episodes. Patients with diverticulitis seen in at least two different colonic locations were classified as the MFD group and compared to the UFD group based on number of episodes, sites of disease, family history, surgeries performed, and postoperative recurrence. RNA-seq was conducted on full-thickness colonic tissues of ten MFD and 11 UFD patients.Results: Twenty-eight patients (6.9%) with MFD were identified. MFD patients had more diverticulitis episodes and were more likely to have positive family history, have right-sided disease, require surgery, and have recurrence after surgery. All MFD patients treated with segmental resection had recurrence, while recurrence was less common in patients undergoing more extensive surgery (P < 0.001). Using RNA-seq, we identified 69 genes that were differentially expressed between MFD and UFD patients. Significantly down-regulated genes were associated with immune response pathways.Conclusions: MFD appears to be a more severe subset of diverticulitis with a possible genetic component. Transcriptomic data suggest that MFD may be associated with alteration of the immune response. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background and Objectives: This study compares surgical and oncological outcomes in patients with Crohn's disease (CD)-related colorectal cancer (CRC) to those with sporadic CRC., Methods: Patients treated between 1983 and 2013 were matched by stage, age, gender, American Society of Anesthesiologists (ASA), cancer site, and adjuvant chemotherapy., Results: For stages I and II, 107 patients were matched (58.9% male, mean age 59 years, 59.8% with ASA score 3). Tumor sites included the right (17.7%), transverse (4.7%), left colon (15.9%), and rectum (61.7%). CD patients exhibited longer operative times, higher pT stages, and 2.60 times the odds of postoperative complications (p = 0.03). Overall and disease-free survival were similar. For stage III, 54 patients were matched (57.4% male, mean age 54 years, 46.3% with ASA score 3). The cancer site distribution was right (29.7%), transverse (3.7%), left colon (18.5%), and rectum (48.1%). CD patients had longer operative times, increased blood loss, more involved lymph nodes, higher pT- and pN-stages. The rates of postoperative complications were not different (p = 0.19). CD-related CRC patients had similar overall (p = 0.06), and local recurrence-free survival (p = 0.07)., Conclusions: Despite facing worse perioperative and pathological characteristics, survival differences in stages I-III CD-related CRC compared with sporadic CRC patients were not significantly different., (© 2024 Wiley Periodicals LLC.)

- Abstract
Background: A prospective IDEAL stage 2a pilot study was carried out at a tertiary care center to evaluate the reliability of a homemade laparoscopic endotrainer, following the MISTEL and IDEAL framework guidelines., Methods: The validated modified (MISTELS) score was used to test the reliability of a low-cost laparoscopic trainer with commonly found components built by surgeons. Basic household materials including a cellular phone (camera source), wifi (linking source) and freely available webcam apps were used for construction. Five basic laparoscopic skills were performed by general surgery resident volunteers with minimal (1-6 months') laparoscopic surgery experience and tested and retested based on efficiency and precision. To determine interrater reliability, two trained observers scored all subjects. The Cronbach alpha test was used to test for internal consistency between tasks. The Interclass correlation coefficient is used for test and retest reliability., Results: 15 (80% male, mean age 28 ± 5 years) residents were included. The interrater and test-retest reliabilities for the total scores of the basic laparoscopic skills tests were 0.952 (95% CI, 0.895-0.981) and 0.64 (95% CI, 0.35-0.77), respectively. The Cronbach Alpha for the first assessment test and retest was 0.83. The MISTELS metrics had excellent reliability, exceeding the threshold level of 0.8., Conclusion: It is possible to assemble a low-cost, reliable trainer at home to enhance laparoscopic skills during residency., (© 2024 Royal Australasian College of Surgeons.)

- Abstract
Purpose: Endometriosis involving the colon and/or rectum (CRE) is operatively managed using various methods. We aimed to determine if a more limited excision is associated with 30-day complications, symptom improvement, and/or recurrence., Methods: This is a retrospective review of consecutive cases of patients who underwent surgical management of CRE between 2010 and 2018. Primary outcomes were the associations between risk factors and symptom improvement, 30-day complications, and time to recurrence. Multivariable logistic regression assessed the independent risk factors., Results: Of 2681 endometriosis cases, 142 [5.3% of total, mean age 35.4 (31.0; 39.0) years, 73.9% stage IV] underwent CRE excision (superficial partial = 66.9%, segmental = 27.5%, full thickness = 1.41%). Minor complications (14.8%) were associated with blood loss [150 (112; 288) vs. 100 (50.0; 200) mls, p = 0.046], Sigmoid involvement [45.5% vs. 12.2%, HR 5.89 (1.4; 22.5), p = 0.01], stoma formation [52.6% vs. 8.9%, HR 10.9 (3.65; 34.1), p < 0.001], and segmental resection [38.5% vs. 5.8%, HR 9.75 (3.54; 30.4), p < 0.001]. Superficial, partial-thickness resections were associated with decreased risk [(4.2% vs. 36.2%), HR 0.08 (0.02; 0.24), p < 0.001]. Factors associated with major complications (8.5%) were blood loss [250 (100; 400) vs. 100 (50.0; 200) mls, p = 0.03], open surgery [31.6% vs. 4.9%, HR 8.74 (2.36; 32.9), p = 0.001], stoma formation [42% vs. 3.3%, HR 20.3 (5.41; 90.0), p < 0.001], and segmental colectomy [28.2% vs. 0.9%, HR 34.6 (6.25; 876), p < 0.001]. Partial-thickness resection was associated with decreased risk ([.05% vs. 23.4%, HR 8.74 (2.36; 32.9), p < 0.001]. 19.1% experienced recurrence. Open surgery [5.2% vs. 21.3%, HR 0.14 (0.02; 1.05), p = 0.027] and superficial partial thickness excision [23.4% vs. 10.6%, HR 2.86 (1.08; 7.59), p = 0.027] were associated. Segmental resection was associated with decreased recurrence risk [7.6% vs. 23.5%, HR 0.27 (0.08; 0.91), p = 0.024]., Conclusion: Limiting resection to partial-thickness or full-thickness disc excision compared to bowel resection may improve complications but increase recurrence risk., (© 2023.

Investigations in a woman with prolonged symptoms of laxative-resistant constipation and recurrent rectal bleeding revealed a giant rectal vascular malformation. Colonoscopy and MRI were performed to rule out malignancy and determine differential diagnoses. Repeated tests were necessary due to inconclusive results. After a definite diagnosis, image-guided, transcutaneously administered sclerotherapy was used. The intervention and postoperative course were uneventful.

- Abstract
Background: Idiopathic myointimal hyperplasia of the mesenteric veins is an extremely rare non-thrombotic mesenteric veno-occlusive disease. The management of idiopathic myointimal hyperplasia of the mesenteric veins is not well-established, and although surgery is the mainstay of treatment, the optimal operation remains unclear. Therefore, we aimed to perform a systematic review to assess the various surgical procedures and associated outcomes for patients with idiopathic myointimal hyperplasia of the mesenteric veins., Methods: A systematic search for articles published from 1946 to April 2022 in MEDLINE, EMBASE, Cinahl, Scopus, Web of Science, and Cochrane Library databases is reported. In addition, we report 4 cases of idiopathic myointimal hyperplasia of the mesenteric veins managed at our institution until March 2023., Results: A total of 53 studies and 88 patients with idiopathic myointimal hyperplasia of the mesenteric veins were included. Most (82%) were male patients, with a mean age of 56.6 years old. The majority (99%) of patients required surgery. Most reports described the involvement of the rectum and sigmoid colon (81%). The most common surgical procedures were Hartmann's procedure (24%) and segmental colectomy (19%); completion proctectomy with ileal pouch-anal anastomosis was performed in 3 (3.4%) cases. In 6 (6.8%) cases, idiopathic myointimal hyperplasia of the mesenteric veins was suspected preoperatively and managed with elective surgery. Four (4.5%) complications were reported. Nearly all (99%) patients achieved remission with surgical intervention., Conclusion: Idiopathic myointimal hyperplasia of the mesenteric veins is a rare pathologic entity infrequently suspected preoperatively and typically diagnosed after surgical resection. Surgical resection with Hartmann's procedure or segmental colectomy was most commonly performed, with completion proctectomy and ileal pouch-anal anastomosis reserved for cases of extensive rectal involvement. Surgical resection was safe and effective, with a low risk of complications and recurrence. Surgical decision-making should be based on the extent of the disease at the time of presentation., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Background: The symptoms of stricturing diverticulitis can overlap with those of colorectal cancer. Additionally, the stricture itself may mask a "hidden" colorectal cancer. We aimed to describe the demographics, operative details and outcomes, including occult colorectal cancer, in a cohort of consecutive resections for presumed diverticular strictures., Methods: In this single-center, retrospective cohort study, all patients undergoing resection for a presumed diverticular stricture between January 2010 and December 2015 were included. Preoperative imaging and colonoscopies were individually reviewed. Only patients with radiographically, endoscopically and/or intraoperatively benign-appearing strictures were included., Results: One hundred fifty patients (72.7% female, mean age = 70.4 ± 11.8 years, 62.7% elective) were included. Only 34 (22.7%) had a complete preoperative colonoscopy. In 95 (63.6% of cohort) patients, the stricture was non-traversable colonoscopically. Overall, 47 (31.3%) patients did not have complete preoperative imaging or a colonoscopy. In total, 53.3% were open procedures and 62% had non-diverted primary anastomosis. Eleven (14.7%) underwent resection of adjacent organs (5 appendixes/5 right colons/7 fallopian tubes ± ovaries/3 small bowel resections/2 partial cystectomies/1 spleen). The median length of stay was 7 (5, 12.5) days. Only 2 cancers (1.3% of patients) involving the stricture (1 invasive moderately differentiated sigmoid adenocarcinoma/1 lymphoma) were found. Three additional cancers were found in organs involved in the inflammatory process (20% of concomitantly resected organs, 1 ovarian carcinoma/1 leukemia in a lymph node/1 appendiceal tumor)., Conclusion: Despite approximately one-third of the cohort not having undergone successful preoperative colonoscopy or imaging, the rate of neoplasia involving diverticular strictures was only 1.3%. A relatively high cancer rate was found in concomitantly resected organs involved in the stricturing process., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Background: Tissue harvesting at the time of surgery offers surgeons and scientists a unique opportunity to discover and better understand disease pathophysiology. Tissue biobanking presents challenges in patient consents, specimen collection, preparation, and storage, but the potential for scientific discovery justifies the effort. Although the number of tissue biobanks is increasing worldwide, information regarding necessary infrastructure, process flow, and management of expected obstacles is lacking., Objective: To provide a framework and motivation for clinician scientists intending to start an intestinal tissue biobank under their direction., Data Sources: The Carlino Family Inflammatory Bowel and Colorectal Diseases Biobank is housed at the Milton S. Hershey Medical Center., Study Selection: Review., Intervention: Implementation of a surgical tissue biobank at a large tertiary care institution., Main Outcome Measures: Assess critical challenges and obstacles over the years as well as keys to the success of the program., Results: Over 2 decades, the institutional biobank grew from an IBD biobank to one which now incorporates thousands of surgical specimens representing numerous colorectal diseases. This was done through a process of refinement focusing on patient recruitment and an efficient consenting and specimen management process. The biobank's success is further insured by institutional, external, and philanthropic support; scientific collaborations; and sharing of biological specimens with other groups of dedicated researchers., Limitations: This is a single-center experience in collecting surgically resected colorectal specimens., Conclusions: Surgical specimen biobanks are essential in studying disease cause using genomics, transcriptomics, and proteomic technologies. Therefore, surgeons, clinicians, and scientists should build biobanks at their institutions to promote further scientific discovery and improve specimen diversity., (Copyright © The ASCRS 2023.)

- Abstract
Purpose: Previously considered a disease of old age, diverticular disease is increasingly prevalent in younger populations. Guidelines on surgical resection have shifted from recommending resection for all young onset patients to an individualized approach. Therefore, we aim to determine demographics and outcomes including radiographic and surgical recurrence rates in patients < 40 years old undergoing resection for diverticular disease., Methods: A retrospective, single center study was performed. All patients ≤ 39 years undergoing operative intervention for left-sided diverticular disease between Jan 2010 and July 2017 were included. Recurrence was determined by individual review of imaging and operative reports., Results: Overall, 147 (n = 107/72.8% male, mean age = 34.93 ± 4.12 years) patients were included. The majority were ASA 1 or 2 (n = 41/27.9% and n = 82/55.8%). The most common surgical indication was uncomplicated diverticulitis (n = 77, 52.4%) followed by perforation (n = 26/17.7%). The majority (n = 108/73.5%) of cases were elective. Seventy-nine (57.3%) of all cases were performed laparoscopically. Primary anastomosis without diversion was the most common surgical outcome (n = 108/73.5%). Median length of stay was 5 (4, 7) days. There was no mortality. There were three (2.0%) intraoperative and 38 (25.9%) postoperative complications. The most common complication was anastomotic leak (n = 6/4.1%). The majority (n = 5) of leaks occurred after elective surgery. Two neoplastic lesions (1.3% of cohort) were found (1 adenoma with low-grade dysplasia/1 polyp cancer). Over a mean follow-up of 96 (74, 123) months, only 2 (1.3%) patients experienced a surgical or radiological recurrence., Conclusion: Both neoplasia and recurrence after resection for diverticular disease in young onset patients are rare. Leaks after primary anastomosis even in the elective setting warrant careful consideration of a defunctioning ileostomy., (© 2023.

- Abstract
Background: Patients commonly use the internet to obtain medical information. Patients in our outpatient setting frequently have incomplete or even incorrect information about hyperthermic intraperitoneal chemotherapy that they have found on the internet. We aimed to assess the quality and content of Web-based information on hyperthermic intraperitoneal chemotherapy using validated and novel scoring systems., Methods: The keywords "HIPEC" and "hyperthermic intraperitoneal chemotherapy" were entered into the most commonly used internet search engines (Google, Bing, and Yahoo). The first 10 websites from each search were analyzed. Website quality was assessed using the validated Journal of the American Medical Association benchmark criteria and DISCERN scoring systems. We created a novel hyperthermic intraperitoneal chemotherapy-specific score with surgeon experts in the field., Results: Eighteen unique websites were identified. The majority (78%) were from academic institutions. The mean total DISCERN score for all websites was 41.8 ± 8.4 (maximum possible points = 75). The mean Journal of the American Medical Association and hyperthermic intraperitoneal chemotherapy-specific scores were 1.72 ± 1.13 (maximum possible score = 4) and 11.5 ± 4.5 (maximum possible score = 31), respectively. The lowest Journal of the American Medical Association scores were in the category of authorship. In total, 78% of websites omitted author details; 83% and 78% included the temperature and duration of hyperthermic intraperitoneal chemotherapy, respectively. Only 39% of websites mentioned complications of hyperthermic intraperitoneal chemotherapy., Conclusion: Web-based information on hyperthermic intraperitoneal chemotherapy is of variable content and quality. None of the websites achieved maximum scores using any of the scoring tools. Less than half of the websites provided any information on possible complications of the procedure. These findings should be highlighted to patients using the internet to obtain information about hyperthermic intraperitoneal chemotherapy., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Background: Patients undergoing colorectal surgery for inflammatory bowel disease (IBD) are recognized to have an increased risk of venous thromboembolism (VTE). The aim of this study was to determine the perioperative risk factors for VTE and to create a predictive scoring system for VTE in the IBD cohort., Methods: The NSQIP-IBD Collaboration Registry from 2017 to 2020 was used to identify patients. Demographics, operative and outcomes data of IBD patients undergoing surgeries for IBD were analysed. A logistic multivariate regression model was performed using all significant variables to develop a predictive scoring system of VTE., Results: Five-thousand and three patients (51.9% male, mean age: 42.7, 42.7% ulcerative colitis) were included in the study. 125 (2.49%) developed VTE. On multivariate analysis ASA grade, ulcerative colitis, sepsis, serum sodium <139 mmol/L, an open abdomen and preoperative inter hospital transfer were associated with greater risk of VTE. Using these 6 significant factors, a risk model was constructed. The risk of VTE with one risk factor was 0.7% and 1.8% with two risk factors. The risk of VTE increased to 3.6% and 4.5% with three and four risk factors respectively. With five and six risk factors, the risk of VTE increased exponentially to 10.9% and 25% respectively., Conclusion: This study shows that there are cumulative risk factors which increase the risk of VTE after surgery for IBD. The risk increases exponentially with more than five risk factors, and extended chemoprophylaxis may not be enough in reducing this risk., (© 2023 The Authors.

- Abstract
Peristomal skin complications (PSCs) are relatively common in ostomy patients, particularly in those with ileostomies. Non-healing irritation presents a clinical challenge and leads to pain and impaired quality of life for patients., Methods: The cases of four ileostomy patients experiencing severe, challenging PSCs refractory to appliance changes, conventional dressings and barrier creams are discussed., Findings: The cases of one male and one female patient with an end ileostomy post-subtotal colectomy for ulcerative colitis, one female with a defunctioning ileostomy post-anterior resection for sigmoid carcinoma and one male with an end ileostomy with a complex Crohn's surgical history are described. Two puffs of a 250 mcg metered dose beclometasone inhaler were applied to the affected skin once or twice daily. Treatment ranged from 6 to 21 days. Complete resolution was seen in all cases., Conclusion: Topical use of a beclometasone inhaler was effective for severe peri-ileostomy PSC secondary to four different aetiologies. Further studies are warranted to determine the effectiveness of this treatment in a larger patient cohort.

- Abstract
Background: Inflammatory bowel disease (IBD) patients are at risk for Clostridioides difficile infection (CDI). The majority of published outcomes data feature medically treated patients. We aimed to analyze outcomes in a large cohort of surgical IBD patients diagnosed with CDI., Methods: All patients with IBD in the ACS NSQIP Colectomy and Proctectomy (2015-2019) modules were identified. The IBD-CDI and IBD cohorts were propensity score weighted on demographic and surgical factors and compared., Results: In the entire unmatched cohort (n = 12,782), 119/0.93% patients were diagnosed with CDI (74.2% Crohn's/25.7% UC/Indeterminate colitis) within 30-days of surgery. After propensity score weighting, IBD-CDI was associated with increased risk of readmission (OR 4.55 [3.09-6.71], p < 0.001), reoperation (3.17 [1.81-5.52], p < 0.001) and any complication (2.16 [1.47-3.17], p < 0.001). Any SSI (2.58 [1.67-3.98]), organ space SSI (2.49 [1.51-4.11], both p < 0.001), prolonged ventilation (4.03 [1.39-11.69],p = 0.01), acute renal failure (15.06 [4.26-53.26],p < 0.001), stroke (12.36 [1.26-121.06],p = 0.03), sepsis (2.4 [1.39-4.15],p = 0.002) and septic shock (3.29 [1.36-7.96],p = 0.008) were also higher in the IBD-CDI cohort. Mean length of stay was increased by 39% in CDI patients., Conclusion: Post colonic resection, IBD-CDI patients have worse outcomes than IBD patients without CDI. These patients represent a particularly vulnerable cohort who require close monitoring for the development of postoperative complications., Competing Interests: Declaration of competing interest Tara M.

- Abstract
Background: The aims of this study were to determine the impact of race and socioeconomics on survival in patients with stage IV colorectal cancer., Methods: A prospective database of stage IV colorectal cancer patients treated at a multi-hospital health system from 2015 to 2019 was retrospectively analyzed. Univariate and multivariate survival analysis using log-rank Mantel-Cox test and Cox proportional hazard model were performed to determine the impact of race, socioeconomic factors, presentation, and treatment on overall survival., Results: 4012 patients were diagnosed with colorectal cancer, of which 803 patients were stage IV. There were 677 (84.3%) White, and 108 (13.4%) Black patients. Black patients have worse 5-year overall survival than white patients (HR 1.43 (1.09-1.87)). Patients who received chemotherapy had significantly better survival than patients who did not receive chemotherapy (HR 0.58 (0.47-0.71)). Black patients have significantly lower rates of receiving chemotherapy as compared to white patients (61.1% vs 75.37%, p = 0.0018)., Conclusion: Patients with Stage IV colorectal cancer have worse survival if they are black, older age, and did not receive chemotherapy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Inc.

- Abstract
Introduction: Colonic self-expanding metal stents (SEMS) can be used to relieve malignant and benign large bowel obstruction (LBO) as a bridge to surgery (BTS) and for palliation. Guidelines suggest the use of fluoroscopic guidance for deployment. This may be difficult to obtain after hours and in certain centers. We aimed to determine the outcomes of stenting under endoscopic guidance alone., Methods: All patients who underwent SEMS insertion in our tertiary referral center between August 2010 and June 2021 were identified from a prospectively maintained database. Patient demographics (age/gender), disease characteristics (benign versus malignant/location/stage), stenting intent (BTS versus palliative), and outcomes (technical success/stoma/time from stenting to resection/death/study end) were analyzed., Results: Fifty-three (n = 39, 73.6% male) patients underwent SEMS insertion. Indications included colorectal carcinoma (n = 48, 90.6%), diverticular stricture (n = 3), and gynecological malignancy (n = 2). In five (9.4%) patients (four BTS and one palliative), SEMSs deployment was not completed because of the inability to pass the guidewire. All underwent emergency surgery. In the BTS cohort (n = 29, median 70.4 [range 40.3-91.8] years), 10 patients underwent neoadjuvant chemoradiotherapy. The permanent stoma rate was 20.7% (n = 6). There was no 30- or 90-d mortality. In the palliative cohort (n = 24, median age 77.1 [range 54.4-91.9]), 16 (66.7%) were deceased at the study end. The median time from stenting to death was 5.2 (2.3-7.9) months., Conclusions: SEMS placed under endoscopic visualization alone, palliatively and as a BTS, had acceptable stoma, morbidity, and mortality rates. These results show that SEMS insertion can be safely performed without fluoroscopy., (Copyright © 2022 Elsevier Inc. All rights reserved.)

182. Crohn's of the Pouch: Now What?
- Author

Connelly TM, Lincango E, and Holubar SD
- Abstract
Total proctocolectomy and ileal pouch anal anastomosis (IPAA) is the gold standard surgical treatment for the majority (∼90%) of ulcerative colitis (UC) patients. In cases of carefully selected Crohn's colitis patients without small bowel or perianal involvement an "intentional IPAA" may be a viable option for disease resection and restoration of intestinal continuity. More commonly, Crohn's is incidentally found either in the resection specimen or, more commonly, when inflammatory complications subsequently arise after pouch construction for UC or indeterminate colitis. These incidental Crohn's pouches may be diagnosed early or late period post-IPAA. Crohn's may manifest within the pouch, in the proximal small bowel, and/or distally in the rectal cuff or anus. Like intestinal Crohn's, Crohn's disease of the pouch may be of an inflammatory, fibrostenosing, or fistulizing phenotype. Treatment depends on the phenotype and includes medical treatment, most commonly in the form of tumor necrosis factor inhibitor medications; however, the newer small molecules offer a potential treatment for these patients. Surgery first entails treating the sequelae of Crohn's and is typically staged. In up to 60% of Crohn's pouches, particularly in fistulizing disease and/or recalcitrant perianal disease, the pouch fails and must be defunctioned or excised. In patients with Crohn's pouches in situ long term, outcomes including quality of life are comparable to patients who underwent IPAA for UC., Competing Interests: Conflict of Interest None declared., (Thieme.

- Abstract
Purpose: Laparoscopic surgery for complicated Crohn's (CD) is often technically challenging. Previous studies are limited by the comparison of heterogeneous cohorts of patients undergoing laparoscopic vs open surgery. We aimed to compare perioperative and long-term outcomes of matched patients undergoing laparoscopic and open colonic and ileocolonic resection. Primary outcomes were operative time, blood loss, and complications. Long-term outcomes were subsequent intraabdominal CD surgery, incisional hernia repair, and stoma reversal rates., Methods: Laparoscopic and open CD patients were 1:1 propensity score matched on age, body mass index, sex, indication, ASA grade, prior abdominal surgery, and postoperative Crohn's medication use based on the laparoscopic approach., Results: A total of 906 patients underwent surgery for complex CD. After propensity matching, 386 were analyzed (193 open/193 lap, 51.3% male, mean age 33.9 + / - 12.6). Mean follow-up was 9.8 (range 7.9-12.1) years. Length of stay [(LOS) 6 (4, 8) vs 8 (5, 11) days, p < 0.001] and operative time [154 (110, 216) vs 176 (126, 239) min, p = 0.03] were shorter in the laparoscopic group. There was no difference in other complications or mortality. After adjusting for postoperative medications, no association was found between operative approach and subsequent intra-abdominal operation or incisional hernia repair. Laparoscopic patients were less likely to have postoperative sepsis [OR 0.40 (0.18, 0.91), p = 0.03]., Conclusion: In the setting of complicated Crohn's, in matched cohorts, laparoscopic surgery is associated with reduced operative times and LOS. Mortality, reoperation, and symptomatic hernia rates were equivalent to open surgery. Patients undergoing laparoscopic surgery are less likely to experience postoperative sepsis., (© 2022.

- Abstract
Background: Right iliac fossa (RIF) pain is a common indication for laparoscopy to diagnose and treat appendicitis. When a macroscopically normal appendix is found, there is no standard consensus regarding excision. Some surgeons remove the appendix due to the risk of microscopic inflammation and to avoid a future, repeat laparoscopy for possible appendicitis. Alternatively, others leave the appendix in situ to avoid morbidity from a potentially unnecessary procedure. We aimed to evaluate the outcomes of patients with macroscopically normal appendices left in situ., Methods: All emergency laparoscopies without appendicectomy between January 1st 2010- December 31st 2020 were identified from theatre records. All operative notes were individually evaluated and comments on the macroscopic appearance of the appendix and any intra-operative pathology were recorded. Only patients undergoing laparoscopy for suspected appendicitis with macroscopically normal appendices were included., Results: A total of 120 patients [median age 21.68 (range 9-90.8) years] were included. The cohort was predominantly female (n=105, 87.5%). Forty-eight patients (40.0%) had a positive finding during index laparoscopy. During a median duration of 94.5 (range 8-131) months' follow-up, 16 patients (13.33%) underwent a repeat laparoscopy for recurrent RIF pain. Thirteen (10.8% of total cohort) subsequently underwent an appendicectomy. Histology confirmed acute appendicitis in six cases (4.17% of entire cohort). On subanalysis of smaller cohort, index laparoscopies with no positive findings (n=72), nine patients (12.5%) underwent appendicectomy with two (2.7%) appendices demonstrating appendicitis on histological examination., Conclusion: 87% of the total cohort with a normal appendix at laparoscopy for RIF pain did not undergo further laparoscopy. Less than 5% of the total cohort and 2.7% of subanalysis cohort had an appendicectomy for histologically-proven appendicitis within the follow-up period. From the evidence in this study, we conclude that leaving the appendix in situ unless macroscopically inflamed is a viable alternative to excision., (© 2022.

- Abstract
Purpose: The shift in the national focus and allocation of resources to the management of COVID19 has led to significant changes to surgical practice including the delay of elective surgery. The aim of this study was to explore the implications of such changes on surgeons., Method: Using a qualitative study design, semi-structured interviews were conducted with general surgery consultants and non-consultant hospital doctors from a major tertiary hospital in the Dublin region between March-May 2020. Data collection proceeded iteratively using a thematic analysis approach with quality controls such as memoing and collaborative analysis., Results: Fourteen surgeons (8 male, 6 female) were interviewed. The majority (n = 11, 78.6%) were NCHDs. Significant themes determined included 'impacts' on a variety of constructs such as performance, self-reported fatigue and wellbeing. Training themes elucidated included the effects of the cancellation of elective admissions on reduced operative exposure for trainees. Senior surgical staff were particularly focused on increased complexity in patient management. New policy requirements such as personal protective equipment use and novel rotas have had implications for aspects of work engagement. The pandemic and subsequent national restrictions imposed has afforded opportunities for improved well-being but also resulted in greater solitude in surgeons., Conclusions: Rhetoric surrounding fatigue management and virus control dominates the conversation on the relationship between COVID-19 and surgery. Tipping the balance back to parity of fatigue management with service delivery in surgery will be key for sustainability of the surgical workforce., (Copyright © 2020 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

- Abstract
Since the first robotic assisted surgery in 1985, the number of procedures performed annually has steadily increased. Bibliometric analysis highlights the key studies that have influenced current practice in a field of interest. We use bibliometric analysis to evaluate the 100 most cited manuscripts on robotic surgery and discuss their content and influence on the evolution of the platform. The terms 'robotic surgery,' 'robot assisted surgery' and 'robot-assisted surgery' were used to search Thomson Reuters Web of Science database for full length, English language manuscripts. The top 100 cited manuscripts were analyzed by manuscript type, surgical specialty, first and last author, institution, year and journal of publication. 14,980 manuscripts were returned. Within the top 100 cited manuscripts, the majority featured urological surgery (n = 28), followed by combined results from multiple surgical subspecialties (n = 15) and colorectal surgery (n = 13). The majority of manuscripts featured case series/reports (n = 42), followed by comparative studies (n = 24). The most cited paper authored by Nelson et al. (432 citations) reviewed technological advances in the field. The year and country with the greatest number of publications were 2009 (n = 15) and the USA (n = 68). The Johns Hopkins University published the most top 100 manuscripts (n = 18). The 100 most cited manuscripts reflect the progression of robotic surgery from a basic instrument-holding platform to today's articulated instruments with 3D technology. From feasibility studies to multicenter trials, this analysis demonstrates how robotic assisted surgery has gained acceptance in urological, colorectal, general, cardiothoracic, orthopedic, maxillofacial and neuro surgery.

- Abstract
Aim: Although commonly the first port of call for medical information, the internet provides unregulated information of variable quality. We aimed to evaluate commonly accessed web-based patient information on diverticulitis using validated and novel scoring systems., Methods: The top internet search engines (Google/Bing/Yahoo) were queried using the keyword 'diverticulitis.' The first 20 websites from each were graded using the DISCERN and Journal of the American Medical Association (JAMA) benchmark criteria. A novel diverticulitis-specific score was devised and applied., Results: Thirty-six unique websites were identified. The mean total DISCERN score for all websites was 39.92 ± 12.44 (range = 18-62). No website achieved the maximum DISCERN score of 75. The mean JAMA and diverticulitis scores were 2.5 ± 1.08 (maximum possible score = 4) and 11.08 ± 4.17 (19 points possible) respectively. Fourteen (35.9%) and 20 (51.2%) did not provide the date of last update and authorship respectively. Thirty-three (84.6%) mentioned surgery as a treatment option; however, the majority (69.7%) did not describe the surgery or the possibility of a stoma. All except two described disease symptoms. Only ten (25.64%) provided information on when to seek further medical advice or help., Conclusion: Web-based information on diverticulitis is of variable content and quality. The majority of top websites describe disease symptoms and aetiology; however, information to prompt seeking medical attention if required, descriptions of surgical procedures and the possibility of stoma creation are poorly described in the majority of websites. These findings should be highlighted to patients utilising the internet to obtain information on diverticulitis., (Copyright © 2018 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

- Abstract
Aim: The definitive diagnosis of acute appendicitis (AA) requires histopathological examination. Various clinical diagnostic scoring systems attempt to reduce negative appendectomy rates. The most commonly used in Western Europe and the USA is the Alvarado score. The Raja Isteri Pengiran Anak Saleha appendicitis (RIPASA) score achieves better sensitivity and specificity in Asian and Middle Eastern populations. We aimed to determine the diagnostic accuracy of the RIPASA score in Irish patients with AA., Methods: All patients who presented to our institution with right iliac fossa pain and clinically suspected AA between January 1 and December 31, 2015, were indentified from our hospital inpatient enquiry database and retrospectively studied. Operating theatre records and histology reports confirmed those who underwent a non-elective operative procedure and the presence or absence of AA. SPSS version 22 was used for statistical analysis. Standard deviation is provided where appropriate., Results: Two hundred eight patients were included in the study (106/51% male, mean age 22.7 ± 9.2 years). One hundred thirty-five (64.9%) had histologically confirmed AA (mean symptom duration = 36.19 ± 15.90 h). At a score ≥7.5, the previously determined score most likely associated with AA in Eastern populations, the RIPASA scoring system demonstrated a sensitivity of 85.39%, specificity of 69.86%, positive predictive value of 84.06%, negative predictive value of 72.86% and diagnostic accuracy of 80% in our cohort., Conclusion: The RIPASA score is a useful tool to aid in the diagnosis of acute appendicitis in the Irish population. A score of ≥7.5 provides sensitivity and specificity exceeding that previously documented for the Alvarado score in Western populations. WHAT DOES THIS PAPER ADD TO THE LITERATURE?: This is the first study evaluating the utility of the RIPASA score in predicting acute appendicitis in a Western population. At a value of 7.5, a cut-off score suggestive of appendicitis in the Eastern population, RIPASA demonstrated a high-sensitivity, specificity, positive predictive value and diagnostic accuracy in our cohort and was more accurate than the commonly used Alvarado score.

- Abstract
Purpose: Bibliometric analysis highlights the key topics and studies which have led to the current understanding and treatment of a disease of interest. In this original article we analyze the 100 most cited manuscripts in the field of colorectal cancer (CRC)., Materials and Methods: The Thomson Reuters Web of Science database with the search terms 'colorectal cancer,' 'colorectal cancer surgery,' 'colon cancer,' 'rectal cancer,' 'colorectal carcinoma,' 'colon carcinoma,' 'rectal carcinoma' and/or 'colonoscopy' was used to identify the manuscripts for the study. Only full length manuscripts were included. The 100 most cited papers were identified and further analyzed by topic, journal, author, year and institution. The journals' 5 year impact factor and Eigenfactor scores were recorded., Results: 146,833 eligible papers were returned. Within the top 100 cited manuscripts, the most studied topic was genetics in CRC (n = 41), followed by chemotherapy (n = 20) and surgical management (n = 7). The most cited paper authored by Fearon et al. (7850 citations) focused on genetic models of tumorgenesis. The NEJM published the highest number of papers (n = 23 with 42,576 citations). The country and year with the greatest number of publications were the USA (n = 62) and 2004 (n = 13) respectively., Conclusion: The most cited manuscripts highlighted in the current work describe the genetic, immunologic, basic science and surgical techniques that have resulted in the current understanding and treatment of CRC. The majority of these works were published in high impact journals and have been cited at least 900 times each reflecting their quality and influence. This work provides a reference of what could be considered as the most influential papers in CRC and serves as a reference for researchers and clinicians as to what makes a 'citable' paper., (Copyright © 2016 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.
