Impact of Prehabilitation on Postoperative Mortality and the Need for Non-Home Discharge in High-Risk Surgical Patients.

Background: The preoperative period is an important target for interventions (eg Surgical Prehabilitation and Readiness [SPAR]) that can improve postoperative outcomes for older patients with comorbidities.

Study Design: To determine whether a preoperative multidisciplinary prehabilitation program (SPAR) reduces postoperative 30-day mortality and the need for non-home discharge in high-risk surgical patients, surgical patients enrolled in a prehabilitation program targeting physical activity, pulmonary function, nutrition, and mindfulness were compared with historical control patients from 1 institution's American College of Surgeons (ACS) NSQIP database. SPAR patients were propensity score-matched 1:3 to pre-SPAR NSQIP patients, and their outcomes were compared.

Sequential histologic evolution of gallbladder inflammation in acute cholecystitis over the first 10 days after onset of symptoms.

Background: The timing of cholecystectomy during acute cholecystitis (AC) is controversial, especially whether it is advisable to perform in patients with duration of symptoms between 3 and 10 days. The purpose of this study is to define clearly the sequential evolution of histological changes following symptoms onset to guide recommendations regarding timing of cholecystectomy.

Methods: We identified patients with AC (2005-2018) who had cholecystectomy within 10 days of symptom onset of a first attack of AC.

Increased Morbidity and Mortality After Hepatectomy for Colorectal Liver Metastases in Frail Patients is Largely Driven by Worse Outcomes After Minor Hepatectomy: It's Not "Just a Wedge".

Background: Frailty is associated with postoperative mortality, but its significance after hepatectomy for colorectal liver metastases (CRLM) is poorly defined. This study evaluated the impact of frailty after hepatectomy for CRLM.

Methods: The study identified 8477 patients in National Surgical Quality Improvement Program databases from 2014 to 2019 and stratified them by frailty score using the risk analysis index as very frail (>90th percentile), frail (75th-90th percentile), or non-frail (< 75th percentile).

Clinical classification of symptomatic heterotopic pancreas of the stomach and duodenum: A case series and systematic literature review.

Background: Heterotopic pancreas (HP) is an aberrant anatomic malformation that occurs most commonly in the upper gastrointestinal tract. While the majority of heterotopic pancreatic lesions are asymptomatic, many manifest severe clinical symptoms which require surgical or endoscopic intervention. Understanding of the clinical manifestations and symptoms of HP is limited due to the lack of large volume studies in the literature.

Cause and outcome of aborting a difficult laparoscopic cholecystectomy due to severe inflammation: a study of operative notes.

Background: Upon encountering a difficult cholecystectomy in which, after a reasonable trial of dissection, anatomical identification has not been attained due to severe inflammation, and the risk of additional dissection is deemed to be hazardous, "bail-out" strategies are encouraged safety valves. One strategy is to abort the cholecystectomy and refer the patient to a HPB center for further management.

Methods: A retrospective review was conducted of cholecystectomies performed by HPB surgeons at our center between 2005 and 2019.

Improved outcomes with minimally invasive pancreaticoduodenectomy in patients with dilated pancreatic ducts: a prospective study.

Background: Little is known about what factors predict better outcomes for patients who undergo minimally invasive pancreaticoduodenectomy (MIPD) versus open pancreaticoduodenectomy (OPD). We hypothesized that patients with dilated pancreatic ducts have improved postoperative outcomes with MIPD compared to OPD.

Methods: All patients undergoing pancreaticoduodenectomy were prospectively followed over a time period of 47 months, and perioperative and pathologic covariates and outcomes were compared.

Enhanced recovery pathway after open pancreaticoduodenectomy reduces postoperative length of hospital stay without reducing composite length of stay.

Background/purpose: There is no data regarding the impact of enhanced recovery pathways (ERP) on composite length of stay (CLOS) after procedures with increased risk of morbidity and mortality, such as pancreaticoduodenectomy.

Methods: Patients undergoing open pancreaticoduodenectomy before and after implementation of ERP were prospectively followed for 90 days after surgery and complications were severity graded using the Modified Accordion Grading System. A retrospective analysis of patient outcomes were compared before and after instituting ERP.

Inability to manage non-severe complications on an outpatient basis increases non-white patient readmission rates after pancreaticoduodenectomy: A large metropolitan tertiary care center experience.

Background: Pancreaticoduodenectomy (PD) has a high rate of readmission, and racial disparities in care could be an important contributor.

Methods: Patients undergoing PD were prospectively followed, and their complications graded using the Modified Accordion Grading System (MAGS). Patient factors and perioperative outcomes for patients with and without postoperative readmission were compared in univariate and multivariate analysis by severity.

Thunderbeat™ Integrated Bipolar and Ultrasonic Forceps in the Whipple Procedure: A Prospective Randomized Trial.

Thunderbeat™ is a device that uses both ultrasonic and advanced bipolar energies to achieve hemostasis. It has been evaluated in a variety of clinical contexts, but no literature exists regarding its application to pancreatic surgery. Using a prospective, randomized controlled trial, we evaluated its safety and efficacy in the Whipple procedure.

Clinical practice guidelines for the management of liver metastases from extrahepatic primary cancers 2021.

Background: Hepatectomy is standard treatment for colorectal liver metastases; however, it is unclear whether liver metastases from other primary cancers should be resected or not. The Japanese Society of Hepato-Biliary-Pancreatic Surgery therefore created clinical practice guidelines for the management of metastatic liver tumors.

Methods: Eight primary diseases were selected based on the number of hepatectomies performed for each malignancy per year.

Less is more in the difficult gallbladder: recent evolution of subtotal cholecystectomy in a single HPB unit.

Introduction: Subtotal cholecystectomy (SC) is a technique to manage the difficult gallbladder and avoid hazardous dissection and biliary injury. Until recently it was used infrequently. However, because of reduced exposure to open total cholecystectomy in resident training, we recently adopted subtotal cholecystectomy as the bail-out procedure of choice for resident teaching.

The clonal evolution of metastatic colorectal cancer.

Tumor heterogeneity and evolution drive treatment resistance in metastatic colorectal cancer (mCRC). Patient-derived xenografts (PDXs) can model mCRC biology; however, their ability to accurately mimic human tumor heterogeneity is unclear. Current genomic studies in mCRC have limited scope and lack matched PDXs.

Feasibility and safety of non-operative management of portal vein aneurysms: a thirty-five year experience.

Background: Portal vein aneurysms (PVAs) are rare, though clinically challenging with post-operative mortality approaching 20% and no evidence-based treatment guidelines. We aim to describe our experience with PVAs and recommend optimum management strategies.

Methods: Demographics and clinical details of patients with PVAs admitted to our institution from 1984 to 2019 were reviewed.

Safe Cholecystectomy Multi-society Practice Guideline and State of the Art Consensus Conference on Prevention of Bile Duct Injury During Cholecystectomy.

Background: BDI is the most common serious complication of laparoscopic cholecystectomy. To address this problem, a multi-society consensus conference was held to develop evidenced-based recommendations for safe cholecystectomy and prevention of BDI.

Methods: Literature reviews were conducted for 18 key questions across 6 broad topics around cholecystectomy directed by a steering group and subject experts from 5 surgical societies (Society of Gastrointestinal and Endoscopic Surgeons, Americas Hepato-Pancreato-Biliary Association, International Hepato-Pancreato-Biliary Association, Society for Surgery of the Alimentary Tract, and European Association for Endoscopic Surgery).
