Introduction Hepatic, pancreatic, and complex biliary (HPB) surgery can be associated with major morbidity and significant mortality. For the past 5 years, the American College of Surgeons–National Surgical Quality Improvement Program (ACS–NSQIP) has gathered robust data on patients undergoing HPB surgery. We sought to use the ACS–NSQIP data to determine which preoperative variables were predictive of adverse outcomes in patients undergoing HPB surgery. Methods Data collected from ACS–NSQIP on patients undergoing hepatic, pancreatic, or complex biliary surgery between 2005 and 2009 were analyzed ( n  = 13,558). Diagnoses and surgical procedures were categorized into 10 and eight groups, respectively. Seventeen preoperative clinical variables were assessed for prediction of 30-day postoperative morbidity and mortality. Multivariate logistic regression was utilized to develop a risk model. Results Of the 13,558 patients who underwent an HPB procedure, 7,321 (54%) had pancreatic, 4,881 (36%) hepatic, and 1,356 (10%) biliary surgery. Overall, 70.3% of patients had a cancer diagnosis. Post-operative complications occurred in 3,850 patients for an overall morbidity of 28.4%. Serious complications occurred in 2,522 (18.6%) patients; 366 patients died for an overall peri-operative mortality of 2.7%. Peri-operative outcome was associated with diagnosis and type of procedure. Hepatic trisectionectomy (5.8%) and total pancreatectomy (5.4%) had the highest 30-day mortality. Of the preoperative variables examined, age >74, dyspnea with moderate exertion, steroid use, prior cardiac procedure, ascites, and pre-operative sepsis were associated with morbidity and mortality (all P  < 0.05). Conclusions While overall morbidity and mortality for HPB surgery are low, peri-operative outcomes are heterogeneous and depend on diagnosis, procedure type, and key clinical factors. By combining these factors, an ACS–NSQIP “HPB Risk Calculator” may be developed in the future to help better risk-stratify patients being considered for complex HPB surgery.

Crohn's disease (CD) management targets mucosal healing on ileocolonoscopy as a treatment goal. We hypothesized that radiologic response is also associated with better long-term outcomes. Small bowel CD patients between 1 January 2002 and 31 October 2014 were identified. All patients had pre-therapy computed tomography enterography (CTE)/magnetic resonance enterography (MRE) with follow-up CTE or MRE after 6 months, or 2 CTE/MREs≥6 months apart while on maintenance therapy. Radiologists characterized inflammation in up to five small bowel lesions per patient. At second CTE/MRE, complete responders had all improved lesions, non-responders had worsening or new lesions, and partial responders had other scenarios. CD-related outcomes of corticosteroid usage, hospitalization, and surgery were assessed using Kaplan-Meier survival analysis and multivariable Cox models. CD patients (n=150), with a median disease duration of 9 years, had 223 inflamed small bowel segments (76 with strictures and 62 with penetrating, non-perianal disease), 49% having ileal distribution. Fifty-five patients (37%) were complete radiologic responders, 39 partial (26%), and 56 non-responders (37%). In multivariable Cox models, complete and partial response decreased risk for steroid usage by over 50% (hazard ratio (HR)s: 0.37 (95% confidence interval (CI), 0.21-0.64); 0.45 (95% CI, 0.26-0.79)), and complete response decreased the risk of subsequent hospitalizations and surgery by over two-thirds (HRs: HR, 0.28 (95% CI, 0.15-0.50); HR, 0.34 (95% CI, 0.18-0.63)). Radiological response to medical therapy is associated with significant reductions in long-term risk of hospitalization, surgery, or corticosteroid usage among small bowel CD patients. These findings suggest the significance of radiological response as a treatment target.

Background Endoscopic management of leaks/fistulas after laparoscopic sleeve gastrectomy (LSG) is gaining popularity in the bariatric surgery. Objectives This study aimed to review the efficacy and safety of over-the-scope-clip (OTSC) system in endoscopic closure of post-LSG leak/fistula. Methods PubMed/Medline and major journals of the field were systematically reviewed for studies on endoscopic closure of post-LSG leaks/fistula by means of the OTSC system. Results A total of ten eligible studies including 195 patients with post-LSG leaks/fistula were identified. The time between LSG and leak/fistula ranged from 1 day to 803 days. Most of the leaks/fistula were located at the proximal staple line, and they sized from 3 to 20 mm. Time between leak diagnosis and OTSC clipping ranged from 0 to 271 days. Thirty-three out of 53 patients (63.5%) required one clip for closure of the lesion. Regarding the OTSC-related complications, a leak occurred in five patients (9.3%) and OTSC migration, stenosis, and tear each in one patient (1.8%). Of the 73 patients with post-LSG leak treated with OTSC, 63 patients had an overall successful closure (86.3%). Conclusion OTSC system is a promising endoscopic approach for management of post-LSG leaks in appropriately selected patients. Unfortunately, most studies are series with a small sample size, short-term follow-up, and mixed data of concomitant procedures with OTSC. Further studies should distinguish the net efficacy of the OTSC system from other concomitant procedures in treatment of post-LSG leak.

BACKGROUND:Increasing surgical access to previously underserved populations in the United States may require a major expansion of the use of operating rooms on weekends to take advantage of unused capacity. Although the so-called weekend effect for surgery has been described in other countries, it is unknown whether US patients undergoing moderate-to-high risk surgery on weekends are more likely to experience worse outcomes than patients undergoing surgery on weekdays. OBJECTIVE:The aim of this study was to determine whether patients undergoing surgery on weekends are more likely to die or experience a major complication compared with patients undergoing surgery on a weekday. RESEARCH DESIGN:Using all-payer data, we conducted a retrospective cohort study of 305,853 patients undergoing isolated coronary artery bypass graft surgery, colorectal surgery, open repair of abdominal aortic aneurysm, endovascular repair of abdominal aortic aneurysm, and lower extremity revascularization. We compared in-hospital mortality and major complications for weekday versus weekend surgery using multivariable logistic regression analysis. RESULTS:After controlling for patient risk and surgery type, weekend elective surgery [adjusted odds ratio (AOR)=3.18; 95% confidence interval (CI), 2.26–4.49; P<0.001] and weekend urgent surgery (AOR=2.11; 95% CI, 1.68–2.66; P<0.001) were associated with a higher risk of death compared with weekday surgery. Weekend elective (AOR=1.58; 95% CI, 1.29–1.93; P<0.001) and weekend urgent surgery (AOR=1.61; 95% CI, 1.42–1.82; P<0.001) were also associated with a higher risk of major complications compared with weekday surgery. CONCLUSIONS:Patients undergoing nonemergent major cardiac and noncardiac surgery on the weekends have a clinically significantly increased risk of death and major complications compared with patients undergoing surgery on weekdays. These findings should prompt decision makers to seek to better understand factors, such physician and nurse staffing, which may contribute to the weekend effect.

Elderly onset (EO) inflammatory bowel disease (IBD) may become a more common entity as a result of population aging and the rising IBD incidence. Its management is challenging, because of multimorbidity, polypharmacy, and frailty. Insight into the long-term outcome is essential for optimal patient counseling and treatment. We studied the incidence and disease outcome of elderly-onset IBD in direct comparison to adult-onset (AO) IBD.MethodsAll 2823 cases with IBD from the Dutch population-based IBD South Limburg cohort, diagnosed between 1991 and 2011, were included. Long-term outcome (hospitalization, surgery, and disease phenotype) was compared between AO (<60 years at diagnosis) and EO (≥60 years at diagnosis) disease, for Crohn's disease (CD) and ulcerative colitis (UC) separately.ResultsIn total, 1162 patients with CD (136 EO/1026 AO) and 1661 patients with UC (373 EO/1288 AO) were included. The EO IBD incidence increased from 11.71 per 100,000 persons in 1991 to 23.66 per 100,000 persons in 2010, P < 0.01. Immunomodulators were less often used in EO CD (61.8% versus 77.1%, P = 0.03) and EO UC (22.8% versus 35.4%, P < 0.01), even as biologicals (25.1% versus 55.1%, P = 0.03 and 7.8% versus 18.0%, P < 0.01, respectively). No differences were observed in surgery risk (CD: hazard ratio [HR] 1.19; 95% confidence interval [CI], 0.85–1.67 and UC: HR, 0.88; 95% CI, 0.53–1.46), or in CD phenotype progression (HR, 0.81; 95% CI, 0.52–1.25), but more patients with EO UC required hospitalization (HR, 1.29; 95% CI, 1.01–1.63).ConclusionsEO IBD is rising, warranting physicians' alertness for IBD in elderly patients. The long-term outcome was not different from AO disease, despite a less frequent use of immunomodulators and biologicals.

The uptake of upper gastrointestinal (GI) robotic surgery in the United Kingdom (UK), and Europe more widely, is expanding rapidly. This study aims to present a current snapshot of the practice and opinions of the upper GI community with reference to robotic surgery, with an emphasis on tertiary cancer (oesophagogastric) resection centres. An electronic survey was circulated to the UK upper GI surgical community via national mailing lists, social media and at an open-invitation conference on robotic upper GI surgery in January 2023. The survey included questions on surgeons' current practice or planned adoption (if any) of robotics at individual and unit level, and their opinions on robotic upper GI surgery in general. Priority ranking and Likert-scale response options were used. In total, 81 respondents from 43 hospitals were included. Thirty-four resectional centres responded, including 30 of 31 (97%) recognised upper GI cancer centres in England. Respondents reported performing robotic surgery in 21 of 34 (61.8%) resectional centres, with a median of 65 procedures per centre performed at the time of the survey (range 0-500, interquartile range 93.75). Every centre without a robotic programme expressed a desire or had active plans to implement one. Respondents ranked surgeon ergonomics as the most important reason for pursuing robotics, followed by improvements in patient outcomes and oncological efficacy. Robotic upper GI practice is nascent but rapidly growing in the UK with plans for uptake in almost all tertiary centres. There is growing opinion that this is likely to become the predominant surgical approach in future with benefits to both patients and surgeons. This snapshot offers a point of reference to all stakeholders in upper GI surgery.

The era of biologics is associated with declining rates of surgery for Crohn's disease (CD), but the impact on surgery for stricturing CD is unknown. Our study aimed to assess nationwide trends in bowel resection surgery for obstruction in CD since the introduction of infliximab for CD in 1998. Using the Nationwide Inpatient Sample, we performed a nationwide analysis, identifying patients hospitalized for CD who underwent bowel resection for an indication of obstruction between 1998 and 2020 (era of biologics). Longitudinal trends in all CD-related resections and resection for obstruction were evaluated. Multivariable logistic regression identified patient and hospital characteristics associated with bowel resection surgery for obstruction. Hospitalizations for all CD-related resections decreased from 12.0% of all hospitalizations in 1998 to 6.9% in 2020, while hospitalizations for CD-related resection for obstructive indication increased from 1.3% to 2.0%. The proportion of resections for obstructive indication amongst all CD-related bowel resections increased from 10.8% in 1998 to 29.1% in 2020. In the multivariable models stratified by elective admission, the increasing year was associated with risk of resection for obstructive indication regardless of urgency (nonelective model: odds ratio, 1.01; 95% CI, 1.00-1.02; elective model: odds ratio, 1.06; 95% CI, 1.04-1.08). In the era of biologics, our findings demonstrate a decreasing annual rate of CD-related bowel resections but an increase in resection for obstructive indication. Our findings highlight the effect of medical therapy on surgical rates overall but suggest limited impact of current medical therapy on need of resection for stricturing disease.

Intestinal-cutaneous fistulas (ICFs) constitute a major surgical challenge. Definitive surgical treatment of ICFs continues to be associated with significant morbidity. The purpose of this study was to utilize a nationwide database to define the morbidity associated with current treatment strategies in the surgical management of ICFs. The 2006–2017 American College of Surgeon National Surgical Quality Improvement datasets (ACS-NSQIP) were used to assess 30-day morbidity and mortality after surgical repair of ICFs. Outcomes for emergent repair were compared to elective repair of ICFs. Overall, 4197 patients undergoing ICF-repair were identified. Mean age was 55.9 (SD 15.3). Patients were generally comorbid (62.9% were in ASA class III). The observed in-hospital mortality was 2.3%. However, the observed morbidity rate was 47.3%. Of the observed morbidity, 35.6% was due to post-operative infectious complications (superficial surgical site infections (SSI), deep SSI, organ/space SSI, wound disruption, pneumonia, urinary tract infection (UTI) sepsis or septic shock). The most common infectious complication was sepsis (13.1%). 30-day readmission rate was 15.3% and the 30-day reoperation rate was 11.0%. Emergent repair was associated with a sevenfold increase in mortality (11.9% vs 1.8%, P < 0.001) The management of patients with ICFs is complex and is associated with significant morbidity. Half of patients undergoing surgical management of ICFs developed in-hospital complications. •Surgical repair of intestinal-cutaneous fistulas is associated with significant morbidity.•Nearly half of the study cohort had a post-operative complication.•Thirty-day re-operative rates were 11.0% and thirty-day readmission rates were 15.3%.•Emergent repair of an intestinal-cutaneous fistula is associated with a sevenfold increase in mortality.

ObjectivesIn the United States, trends in the initial treatment approach for ovarian cancer reflect a shift in paradigm toward the increased use of neoadjuvant chemotherapy and interval cytoreductive surgery. The aim of this study was to evaluate the trends in surgical cytoreductive procedures in ovarian cancer patients who underwent either primary or interval cytoreductive surgery.MethodsThis retrospective, population-based study examined patients with stage III/IV ovarian cancer diagnosed between January 2000 and December 2013 identified using SEER-Medicare. Small or large bowel resection, ostomy creation, and upper abdominal procedures were identified using relevant billing codes and compared over time. A 1:1 primary and interval cytoreductive propensity matched cohort was created using demographic and clinical variables. 30-day complications and the use of acute care services were compared.ResultsA total of 5417 women were identified. 34% underwent bowel resections, 16% ostomy creation, and 8% upper abdominal procedures. There was an increase in bowel resections and upper abdominal procedures from 2000 to 2013 in patients who underwent primary cytoreductive surgery. Compared with patients who received primary cytoreduction, patients who underwent interval cytoreductive surgery were less likely to undergo bowel resection (OR=0.50; 95% CI [0.41, 0.61]) or ostomy creation (OR=0.48; 95% CI [0.42, 0.56]). Upper abdominal procedures did not differ between groups. For patients who underwent primary cytoreductive surgery, these procedures were associated with intensive care unit stay (4.6% vs <2%, P<0.01). In both primary and interval cytoreductive surgery patients, the receipt of bowel and upper abdominal procedures was associated with multiple 30-day postoperative complications and higher rates of readmission and emergency room visits.ConclusionsThe performance of upper abdominal procedures in ovarian cancer patients increased from 2000 to 2013. Interval cytoreductive surgery was associated with decreased likelihood of bowel surgery. In matched primary and interval cytoreductive surgery cohorts, the receipt of these procedures were associated with the increased likelihood of postoperative complications and use of acute care services.

ObjectiveThe objective was to describe outcomes and investigate factors affecting prognosis at 1 year post intervention for infants with surgical necrotising enterocolitis (NEC).DesignUsing the British Association of Paediatric Surgeons Congenital Anomalies Surveillance System, we conducted a prospective, multicentre cohort study of every infant reported to require surgical intervention for NEC in the UK and Ireland between 1 March 2013 and 28 February 2014. Association of independent variables with 1-year mortality was investigated using multivariable logistic regression analysis.SettingAll 28 paediatric surgical centres in the UK and Ireland.PatientsInfants were eligible for inclusion if they were diagnosed with NEC and deemed to require surgical intervention, regardless of whether that intervention was delivered.OutcomesPrimary outcome was mortality within 1 year of the decision to intervene surgically.Results236 infants were included in the study. 208 (88%) infants had 1-year follow-up. 59 of the 203 infants with known survival status (29%, 95% CI 23% to 36%) died within 1 year of the decision to intervene surgically. Following adjustment, key factors associated with reduced 1-year mortality included older gestational age at birth (adjusted OR (aOR) 0.87, 95% CI 0.78 to 0.96). Being small for gestational age (SGA) (aOR 3.6, 95% CI 1.4 to 9.5) and requiring parenteral nutrition at 28 days post-decision to intervene surgically (aOR 3.5, 95% CI 1.1 to 11.03) were associated with increased 1-year mortality.ConclusionsParents of infants undergoing surgery for NEC should be counselled that there is approximately a 1:3 risk of death in the first post-operative year but that the risk is lower for infants who are of greater gestational age at birth, who are not SGA and who do not require parenteral nutrition at 28 days post-intervention.
