Summary Background 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov , NCT03471494 . Findings Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Patient: Female, 71-year-old Final Diagnosis: Hepatic epithelioid angiomyolipoma Symptoms: Abdominal pain Medication:— Clinical Procedure: — Specialty: Pathology • Surgery Objective: Rare disease Background: The World Health Organization classification of premalignant gallbladder lesions includes adenomas, intraductal papillary neoplasms, biliary intraepithelial neoplasia, and intracystic papillary neoplasms. Noninvasive neo-plastic lesions >1 cm that originate from the pancreatobiliary system are defined as intraductal papillary neoplasia when they occur in the biliary ducts. The clinical and pathological features of preinvasive lesions arising in the gallbladder are not yet well defined. However, the most widely accepted classification is that of intracholecystic papillary neoplasm (ICPN). Case Report: We present the case of a 71-year-old woman referred to a General Surgery outpatient clinic for suspicious findings on imaging of the gallbladder, namely irregular infundibular parietal thickening. The patient underwent a laparoscopic cholecystectomy and histological examination revealed a thickened gallbladder with mucosa partially surrounded by ICPN with an intestinal pattern and some foci of low-grade dysplasia but no foci of high-grade dysplasia or invasive neoplasia. At follow-up at 30 months, the patient remains clinically well, with no changes visible on computed tomography scan. Conclusions: ICPN of the gallbladder appears to be part of a spectrum of alterations encompassing bile duct or pancreatic lesions. Although it is uncommon, more than half of the lesions are known to have foci of invasive neoplasia at the time of diagnosis. Despite that, the prognosis for these neoplasms is more favorable than for gallbladder neoplasia that originates from another type of lesion. Pathological study of ICPN is essential to define the main characteristics that impact prognosis and survival in these patients.

HighlightsAcute appendicitis is the main indication for surgery during pregnancy.Although pregnancy is not a risk factor for acute appendicitis, appendix rupture is higher amongst pregnant women.During pregnancy, delayed diagnosis is the main factor for poor prognosis as it allows for disease progression.Laparostomy constitutes a damage control gesture,preventing abdominal compartment syndrome and allowing subsequent surgical revision.Principles of the abdominal sepsis and damage control approach are reproducible in the pregnant woman.

Cholecystoenteric fistulas occur as a result of a chronic inflammatory insult involving the gallbladder and the erosion of both its wall and a bowel segment. When the fistula develops, it creates a pathway for gallstones to migrate and cause an intestinal obstruction, known as gallstone ileus. When it obstructs the gastric outlet, a proximal variant of gallstone ileus occurs, known as Bouveret's syndrome.A 65-year-old man presented to the emergency department with a three-day history of epigastric and right upper quadrant pain and persistent vomiting, preceded by unintentional weight loss of 15 kg over three months. Endoscopic and complementary imaging studies identified a concurrent gastric outlet obstruction caused by a lodged gallstone in the duodenal bulb and gallstone ileus.The patient underwent an urgent exploratory laparotomy and was submitted to an enterolithotomy and gastrolithotomy. Due to a sudden deterioration on the fourth postoperative day, he underwent an emergent re-laparotomy that found fecal peritonitis and complete dehiscence of both closures. The patient was then managed with damage control surgery. An atypical gastric resection and enterectomy of the distal ileum were performed and the patient was admitted to the intensive care unit in temporary abdominal closure (laparostomy). The patient failed to improve and died on the same day. Ultimately, the patient's multiple comorbidities, including morbid obesity, malnutrition, and diabetes, contributed to poor tissue healing and the fatal outcome.Gallstone ileus and Bouveret's syndrome are two rare complications of cholecystoduodenal fistulas that have not yet been reported to occur simultaneously. Both intestinal and gastric obstruction makes the surgical approach the first-line treatment.
