lity association as well as how these may evolve in the future in a dynamic region such as South Asia will be an important area for future research. Studies on viable adaptation options to high temperatures for a region that is a hotspot for climate vulnerability, urbanisation and population growth are also needed.
The evidence base on temperature impacts on mortality in South Asia is limited due to the small number of studies, their skewed geographical distribution and methodological weaknesses. Understanding the main determinants of the temperature-mortality association as well as how these may evolve in the future in a dynamic region such as South Asia will be an important area for future research. Studies on viable adaptation options to high temperatures for a region that is a hotspot for climate vulnerability, urbanisation and population growth are also needed.
Acute pancreatitis (AP) is considered one of the most common gastrointestinal disorders; the annual worldwide incidence for AP is 4.9-73.4 cases / 100,000 people and the total mortality rate is 4-8%, increasing to 33% in patients with infected necrosis. This study aims to assess the outcome of providing standardized evidence-based care to patients with acute biliary pancreatitis.

Thirty patients diagnosed with acute biliary pancreatitis, were enrolled in this study and managed according to the Japanese guidelines, 2015 with a complementary scope on other recent guidelines.

Out of 30 patients in the study, 60% were females. Twenty-five cases were presented in the early phase of the disease while the rest presented in the late phase. Gallstones were the commonest cause (80%). The complications encountered were a systemic complication in one case, organ failure in three cases, and the local complications in the form of fluid collections in (43.3%) of cases.Out of 30 patients, 6 patients had an intervention. The main approach was minimally invasive techniques (4 cases), Open approach was performed in 2 cases. The total mortality rate was 10%. Most mild cases were discharged within one week from admission. Cases readmitted with recurrent attacks of acute pancreatitis were 3 cases, one male and 2 females.

By applying guidelines in the management of acute biliary pancreatitis, we can reduce disease-related morbidity and mortality. Besides, we can reduce the costs of medical services with the proper investment of healthcare resources.

Retained gallstones post-cholecystectomy act as a nidus for abscess formation. It is unusual for intraabdominal abscesses to remain asymptomatic due to its propensity to cause inflammation and irritation to the peritoneum.

A 73-year-old female presented with acute onset of right-sided abdominal pain and fever. Her past surgical history was significant for a cholecystectomy in 2010, hysterectomy, and partial nephrectomy. She was diagnosed with an intraabdominal abscess secondary to a retained gallstone post-cholecystectomy. She underwent laparoscopic surgery to drain and remove the abscess. The patient's abdominal pain improved, remains afebrile, and is passing stool regularly.

Gallbladder perforation is common and is dependent on the integrity of the gallbladder and surrounding structures. It is unusual for an intra-abdominal abscess to develop so late following gallstone spillage. This example brings to light the potential long-term sequelae of gallbladder perforation and future complications.

This case highlights the importance of irrigation of the peritoneal cavity and retrieval any spilled gallstones during surgery in the event of gallbladder perforation.

Sex cord tumors with annular tubules (SCTAT) are very rare neoplasms comprising less than 1% of sex cord ovarian tumors. They usually occur in women of reproductive age and tend to be associated with Peutz Jeghers Syndrome (PJS), be bilateral, multifocal, and small. When diagnosed in older patients they are often described as sporadic, unilateral, predominantly cystic and bigger.

A bilateral hysterosalpingo-oophorectomy was performed in a seventy-one year-old-woman with postmenopausal bleeding showing no features of PJS. A bilateral SCTAT was diagnosed, associated with a focus of Leydig cell hyperplasia, an endometrial polyp and endomethroid intraepithelial neoplasia.

SCTAT is a very rare histological variant in postmenopausal women. The case we present is special, different to what has been reported in the literature regarding these tumors.

It is important to be aware that SCTATs can also be present in older women, they can be bilateral despite not being related to PJS syndrome and must be considered as a differential diagnosis in ovarian tumors.

Intestinal malrotation is a rare etiology of chylous ascites in adolescents. Chylous ascites is caused by lymphatic system disarrangement, which can result in an anomalous build-up of a lymphatic fluid rich in lipid, namely chyle in the peritoneal cavity.

We present a case of a 16-year-old Saudi Arabian male who came to the emergency department with right upper quadrant pain associated with difficulty in passing stool for one day and a history of congenital diaphragmatic hernia (CDH) repair at the age of 4 months. Free fluid in the abdomen was noticed in the bedside ultrasound. Abdominopelvic computed tomography revealed dilated small bowel loops and a whirl sign of the mesentery, which indicated intestinal torsion. The patient was treated using Ladd's procedure, and a large volume of chylous fluid was removed from the abdomen. Postoperatively, the abdominal drain revealed no chyle, and the patient was followed-up as an outpatient at which point, he reported no abdominal pain.

Intestinal malrotation is more commonly reported in children and associated with congenital chylous ascites. Chylous ascites by itself is a rare occurrence, and very few cases attribute it to intestinal malrotation in adults. Surgical management with Ladd's procedure is a well-documented surgery in pediatric patients, and yet it was successfully performed in our adolescent patient.

Surgical management of chylous ascites secondary to intestinal malrotation in an adolescent, which is considered novel in this age group, including peritoneal lavage of chyle, resulted in favorable outcomes.

Aortoenteric fistula (AEF) is a rare condition and consists of an abnormal communication between the aorta and the gastrointestinal (GI) tract. The duodenum is the most common location. Fistulas involving the stomach are very uncommon and account for only 2% of the cases. Selleckchem Semagacestat AEF typically results in rapid and fatal exsanguination as diagnosis is frequently missed or made too late (Bixby et al., 2018; Kougias et al., 2003; Lookman, 1959; Genc et al., 2000; Ong et al., 2019; Li et al., 2020).

A 59 years old female with a history of Nissen fundoplication presented with lower gastrointestinal bleeding. Esophagogastroduodenoscopy (EGD) showed a large blood clot in the gastric fundus with no visible source of active bleeding. A mesenteric angiogram, performed for persistent gastro-intestinal bleeding and following two episodes of cardiac arrest, showed no evidence of active bleeding. The left gastric artery was prophylactically embolized. Persistent hemorrhage prompted an exploratory laparotomy followed by a left thoracotomy and confirmed the diagnosis of an aortogastric fistula (AGF). The patient expired intra-operatively.

AGF is a very rare but often fatal condition (Busuttil and Goldstone, 2001). Computerized tomography angiography (CTA) can be a key to the diagnosis (Raman et al., 2012). EGD and catheter angiography have low sensitivity (Kuhara et al., 2015; Manduch et al., 2008). Definitive diagnosis is usually made during surgical exploration or autopsy (Wasvary et al., 1997). While open surgical repair is considered the gold standard therapy, endovascular therapy is becoming the preferred initial treatment option (Bixby et al., 2018).

AGF should be considered in the differential diagnosis of GI bleeding, especially in patients with massive hemorrhage where EGD and mesenteric angiography are not diagnostic.

Metastatic melanoma in the popliteal fossa is extremely rare with less than 5% of metastatic deposits from melanomas in the leg and foot draining into the popliteal region, while the majority drain to the inguinal region. If popliteal spread is clinically overlooked, it may lead to recurrence. Together with the accompanying literature review, this case report emphasises the need for thorough clinical and radiological assessment in the management of malignant melanomas of the lower extremity.

A 66-year-old gentleman presented with metastatic melanoma to the right popliteal fossa three years after the diagnosis of a primary lesion in the right mid-calf with ipsilateral inguinal lymph node metastasis for which he underwent a right wide local excision and complete groin lymph node dissection.

Studies show that a lesion anywhere below the knee can metastasize to the popliteal fossa. The groin can be the primary or secondary lymphatic drainage site in conjunction with the popliteal fossa. Concurrent popliteal and inguinal drainage may either reflect two separate lymphatic channels with popliteal nodes being the primary drainage site, or a single channel which drains to the popliteal basin as an interval node. Hence, popliteal lymph nodes should be carefully assessed in distal lower extremity lesions including melanomas. Modalities to delineate lymphatic flow and identify micrometastatic deposits should be used and when metastatic popliteal disease is identified, radical popliteal dissection is advised.

Proper clinical assessment, good surgical technique, a high index of suspicion, and active surveillance are all essential to ensure early detection of metastasis to the popliteal region.

Upper gastrointestinal bleeding is one of the major manifestations of the stomach's gastrointestinal stromal tumors; when gastric GISTs bleed, they are associated with a poor prognosis and must be treated promptly to avoid dangerous complications. A worrisome side effect of the Covid-19 pandemic is the delay in surgical treatment for seriously ill patients, a rise in surgical complications due to delayed care, lack of access to the healthcare system, and patients' hesitancy to seek care due to fear of the virus. In Ecuador, where limitations were present even in the absence of a pandemic, we are yet to fully know the full extent of the damage this pandemic has caused to ourselves and our patients.

We present the case of a 51-year-old female; she presented with upper gastrointestinal bleeding, and a gastric GIST was diagnosed. Due to the size and the symptoms, surgery was planned. Nonetheless, as Ecuador was hit hard by the Covid-19 pandemic to cope with the respiratory patients, surgeries were delayed or canceled.
