Outcomes and quality of life after partial pancreatectomy for noninsulinoma pancreatogenous hypoglycemia from diffuse islet cell disease.

Background: Noninsulinoma pancreatogenous hypoglycemia (NIPH) is a rare cause of hypoglycemia, especially affecting postbariatric surgery patients, related to excessive insulin secretion. Partial pancreatectomy controls hypoglycemia in the early postoperative period; however, multiple patients have experienced symptomatic relapse. The study goal was to assess frequency and severity of recurrent symptoms in operated patients.

Biopsy of pheochromocytomas and paragangliomas: potential for disaster.

Background: Pheochromocytomas and paragangliomas are highly vascular neuroendocrine neoplasms that often secrete catecholamines. Percutaneous biopsy has been associated with life-threatening hemorrhage, hypertensive crisis, capsular disruption with tumor implantation, and death. We sought to determine the outcomes of biopsy in 20 consecutive patients.

Negligible effect of selective preoperative biliary drainage on perioperative resuscitation, morbidity, and mortality in patients undergoing pancreaticoduodenectomy.

Objective: To examine the effect of selective preoperative biliary drainage (BD) on perioperative resuscitation, morbidity, and mortality in patients undergoing pancreaticoduodenectomy. Biliary drainage prior to pancreaticoduodenectomy remains controversial. Proponents argue that it facilitates referral to high-volume tertiary centers, while detractors maintain that it increases surgical morbidity and mortality.

Benefit of postoperative adjuvant therapy for pancreatic cancer: A population-based analysis.

Background: Despite the recent completion of several trials of adjuvant therapy after resection for pancreatic adenocarcinoma, the absolute impact on survival and the identification of appropriate patients for treatment has remained controversial. In the current study, the authors sought to identify the impact of adjuvant therapy and factors associated with any improvement in survival after resection of pancreatic cancer.

Methods: Through the California Cancer Registry, all California residents diagnosed with pancreatic cancer between 1994 and 2002 were identified.

A prospective, blinded trial of touch prep analysis versus frozen section for intraoperative evaluation of sentinel lymph nodes in breast cancer.

Background: Sentinel lymph node biopsy (SLNB) has largely replaced axillary dissection (ALND) for axillary staging in early breast cancer. However, intense pathologic evaluation is not routinely available intraoperatively; therefore, patients with SLN metastasis may require a second surgery for completion ALND. We hypothesized that a single-section approach (by either frozen section [FS] or touch preparation analysis [TPA]) could be accurate for intraoperative SLN evaluation.

Diffusion of surgical techniques in early stage breast cancer: variables related to adoption and implementation of sentinel lymph node biopsy.

Background: Understanding how physicians acquire and adopt new technologies for cancer diagnosis and treatment is poorly understood, yet is critical to the dissemination of evidence-based practices. Sentinel lymph node biopsy (SLNB) has recently become a standard technique for axillary staging in early breast cancer and is an ideal platform for studying medical technology diffusion. We sought to describe the timing of SLNB adoption and patterns of surgeon interactions with the following educational sources: local university training program, surgical literature, national meetings/courses, national specialty centers, and other local surgeons.

Upstaging and improved survival of early breast cancer patients after implementation of sentinel node biopsy for axillary staging.

Background: Sentinel lymph node biopsy (SLNB) has become a standard for axillary staging for early breast cancer patients. Prior studies suggest that SLNB may be more sensitive for the identification of lymph node disease than axillary lymph node dissection (ALND). We hypothesized that SLNB use increases the incidence of node-positivity in early breast cancer patients compared to ALND.
