Sarcopenia influences the kinetic growth rate after ALPPS
Associating liver partition and portal vein ligation for staged hepatectomy induces rapid and effective hypertrophy of the future liver remnant to prevent postoperative liver failure. The aim of this study was to determine cofactors, including sarcopenia, influencing the kinetic growth rate, and subsequently future liver remnant, in terms of safety, complications, and posthepatectomy liver failure.

Who ’s to blame for the inadequate lymph node yield?
I learned early in my surgical training that pelvic surgery is an unforgiving sport. My attending surgeon at the time, Dr Michael Porter, aptly described a proctectomy as “operating in a glass jar on something that’s the same size as the jar.” That was almost 20 years ago, and surgery for rectal cancer has certainly improved in the interim, but there is still significant variability in surgical quality and patient outcomes. One well-known and longstanding marke r of surgical quality is lymph node yield (LNY), which has conventionally been tied to the extent of surgical resection and height of vessel ligation.

Intraoperative adverse events grading tools and their role in honest and accurate reporting of surgical outcomes
Employing a standardized intraoperative adverse event (iAE) classification grading system,1 Gawaria et  al reported that iAEs occurred during 34% of visceral surgeries and 28% of nonvisceral surgeries. The authors also found that an increasing iAE grade was associated with an increased incidence of postoperative complications and prolonged length of stay.2 We commend the authors for their thoughtful approach to understanding the interplay of iAEs, their timing, and severity.

Perioperative outcomes of pheochromocytoma/paraganglioma surgery preceded by Takotsubo-like cardiomyopathy
Pheochromocytomas and paragangliomas can induce severe cardiovascular manifestations such as Takotsubo-like cardiomyopathy. What the perioperative outcomes are of patients presenting with pheochromocytomas/paragangliomas preceded by Takotsubo-like cardiomyopathy remains an unresolved question. (Source: Surgery)

Variability in pediatric appendectomy: The association between disposable supply cost and procedure duration
Pediatric appendicitis accounts for a notable proportion of health care use and cost in the United States. To identify opportunities for cost savings during pediatric laparoscopic appendectomy, this study assessed whether surgeons' use of costlier disposable supplies correlated with procedure duration and patient outcomes.

Invited Commentary on “Fragmentation of Practice: The Adverse Effect of Surgeons Moving Around”
Innumerable factors contribute to postoperative outcome. Various patient, physician, health system, and infrastructure-level variables have been shown to influence these outcomes and impact health care cost and delivery.1 However, the level to which surgeon-driven factors, such as procedure-specific case volume across different hospitals, and familiarity with a specific operating room team/hospital system affect outcomes is relatively unknown. While it has been previously shown that outcomes improve with increased case volumes, the potential patient, surgeon, and system-level impact of surgeons operating at multiple hospit...

Twenty-two –year evolution of a Medical Breast Service: Filling the important gaps between breast surgery and medical oncology
Historically, surgeons have provided subspecialty breast care. The development of a robust medical breast program in a large academic center staffed by trained primary care providers initially showed a shift in care of benign breast disease away from surgeons. In this review, we aim to revisit the practice after 20 years. Medical patients are defined as patients with symptomatic issues (eg, pain or lump), those at increased risk (due to family history, genetic mutations, or benign atypical lesions), or survivors in need of long-term care.

Influence of intraoperative fluid replacement on ampicillin serum levels and surgical site infections
Surgical site infections (SSI) occur despite antimicrobial prophylaxis and increase postoperative morbidity and mortality. This could be caused by an intraoperative decrease in antibiotic serum concentrations such as ampicillin after major abdominal surgery due to blood loss and fluid therapy, which possibly promotes SSI. This hypothesis was tested in the present study. (Source: Surgery)
