Journal Review in Emergency General Surgery: STOP-IT - What a Decade of Data Has Taught Us
Behind The Knife: The Surgery PodcastShow Notes
It’s postoperative day four after surgery for a perforated colon. The source appears controlled, but the patient is still intubated, the white count is eighteen, and nobody feels comfortable stopping piperacillin–tazobactam. Is four days really enough? Does the ICU buy another four—or is it time to ask what we’re missing? Join Drs. Rushabh Dev, Skye Shultz, Kelly Ray, Desra Fletcher, and Brycen Ratcliffe from the Emergency General Surgery team in Tiger Country at Mizzou as they revisit STOP-IT and examine what more than a decade of evidence has added to the management of complicated intra-abdominal infection. In this EGS Journal Review, the team appraises the landmark trial, explores its subgroup analyses and limitations, and puts contemporary SIS, IDSA, AAST, and Surviving Sepsis guidance into context. The discussion moves from source control and antibiotic duration to resistant organisms, cultures, de-escalation, ICU dosing, and the role of procalcitonin. For most complicated intra-abdominal infections, approximately four days after adequate source control remains the default. Persistent illness should prompt a search for failed source control, ineffective therapy, or another diagnosis before simply extending the stop date.

Learning Objectives By the end of this episode, listeners should be able to: · Describe the design, principal results, strengths, and limitations of STOP-IT, including why adequate source control is essential to applying its findings. · Apply short-course therapy after adequate operative or percutaneous source control and explain why sepsis alone, obesity, or diabetes does not automatically require a longer course. · Distinguish the four-day default from the weaker SIS recommendation supporting up to eight days in selected critically ill patients after adequate source control. · Recognize persistent or worsening illness that warrants reassessment of source control, drain function, microbiology, drug exposure, or alternative diagnoses. · Differentiate the treatment scope of SIS guidance from the diagnostic and microbiology focus of IDSA 2024, the AAST surgical ICU consensus, and broader sepsis and antimicrobial-resistance guidance. · Select and de-escalate antimicrobials using infection setting, resistance risk, cultures, local susceptibility data, and patient-specific dosing considerations. · Explain the limited adjunctive role of procalcitonin in antibiotic discontinuation when duration remains uncertain, including the implications of ADAPT-Sepsis.

In this episode of the Behind the Knife Global Surgery Series, we explore what it actually takes to build a meaningful career in global surgery. Global surgery is not a single specialty or job title—it is a broad field that intersects with clinical care, education, research, policy, advocacy, implementation science, and health-system strengthening. So how do trainees and early-career surgeons find their place in it?
Open the capsule, quit the cigarettes, and know when to cut: the essentials of managing marginal ulcers after bypass. Marginal ulcers are among the most common complications after Roux-en-Y gastric bypass, with a pooled prevalence around 4.6%, and they span everything from mild postprandial pain to perforation with peritonitis. In this episode, our expert panel works through three clinical scenarios (an uncomplicated early ulcer, a refractory ulcer with recurrent stricture, and a perforated ulcer with peritonitis) to build a practical framework for prevention, workup, medical therapy, and surgical escalation.

It’s 2 a.m. and a patient with a GSW to the thigh is rolling into the trauma bay. He’s hypotensive, tachycardic, and has a tourniquet in place. Do you get a CTA or go straight to the OR? What do you do with the tourniquet? Join us as we work through this and two other cases of extremity vascular trauma and break down the literature to answer these questions and discuss how we should approach these challenging injuries.
