Adolescent girl with a huge pelvic collection
A 14-year-old previously healthy girl was admitted to our Pediatric Surgical Department for a 10-day history of fever (>38.5 °C) associated with abdominal pain, vomiting, and diarrhea. A blood test showed a neutrophilic leukocytosis with elevated levels of C-reactive protein (white blood cells 25,000 mm3, neutrophils 80%, C-reactive protein 206 mg/L). Physical examination revealed a soft, nondistended abdomen with locali zed lower quadrants tenderness. An abdominal ultrasonography (US) documented a cavity distended by superfluid material and diffuse adipose-tissue hyperplasia. (Source: Surgery)

Necrotic abdominal wall: What is the cause?
A healthy 28-year-old man presented to our tertiary care emergency department with a several-month history of worsening epigastric abdominal pain and the recent development of an abdominal wall abscess. The patient had undergone a laparoscopic anterior resection for failed medical management of diverticulitis 1 year prior. On initial assessment, this abdominal wall abscess was far removed from all previous laparoscopic port site scars. A bedside incision and drainage was performed, and the patient was discharged home with oral antibiotics. (Source: Surgery)

Challenges in recovery of elective surgery systems
Surgery is being neglected in pandemic recovery plans. The overlapping worldwide problems that already existed, including timely access to surgeons, affordability, and bed pressures, were suddenly magnified by the COVID-19 pandemic. These problems are further exacerbated in the Global South, where limited access and affordability of safe surgery had already been identified as major problems by the Lancet Commission on Global Surgery in 2015. A new global lens needs to be focused on solutions to provide stable surgical systems in all countries over the next decade, considering existing problems, the risks of new COVID-19 va...

Laparoscopic versus open liver resection for intrahepatic cholangiocarcinoma: Report of an international multicenter cohort study with propensity score matching
Intrahepatic cholangiocarcinoma is a rare disease with a poor prognosis. In patients where surgical resection is possible, outcome is influenced by perioperative morbidity and lymph node status. Laparoscopic liver resection is associated with improved clinical and oncological outcomes in primary and metastatic liver cancer compared with open liver resection, but evidence on intrahepatic cholangiocarcinoma is still insufficient.The primary aim of this study was to compare overall survival for a large series of patients treated for intrahepatic cholangiocarcinoma by open or laparoscopic approach.

However, although the collagen score of the proximal doughnut showed no difference between the patients with AL and non-AL in the study, I think it is more useful to prevent AL. (Source: Surgery)

Falling Through the Cracks - Evaluating the Role of non-Acute ‘Surgical Liaison’ Personnel during COVID-19 – A Narrative Review.

An abundance of literature has established emergency general surgery (EGS) as a defined subset of acute surgical diseases that are associated with disproportionate mortality, morbidity, and cost compared with similar elective surgical conditions.1 Yet despite wide recognition of the substantial public health burden of EGS, systems of care to support and guide the care of EGS patients remain underdeveloped compared with other time-sensitive conditions such as trauma or emergency cardiac illness. The impact of this uncoordinated and often fragmented system is felt most acutely by patients requiring interhospital transfer to ...
