Oncological resection and perioperative outcomes of robotic, laparoscopic and open pancreatoduodenectomy for ampullary adenocarcinoma: a propensity score matched international multicenter cohort study.

Background: Ampullary adenocarcinoma (AAC) typically presents at an early stage due to biliary obstruction and therefore might be specifically suitable for minimally invasive pancreatoduodenectomy (MIPD). However, studies assessing MIPD specifically for AAC, including the robotic and laparoscopic approach, are limited. The aim of this study is to compare short- and long-term oncological resection and perioperative outcomes of robotic (RPD), laparoscopic (LPD) and open pancreatoduodenectomy (OPD) performed specifically for AAC.

The Five Periampullary Cancers, not Just Different Siblings but Different Families: An International Multicenter Cohort Study.

Background: Cancer arising in the periampullary region can be anatomically classified in pancreatic ductal adenocarcinoma (PDAC), distal cholangiocarcinoma (dCCA), duodenal adenocarcinoma (DAC), and ampullary carcinoma. Based on histopathology, ampullary carcinoma is currently subdivided in intestinal (AmpIT), pancreatobiliary (AmpPB), and mixed subtypes. Despite close anatomical resemblance, it is unclear how ampullary subtypes relate to the remaining periampullary cancers in tumor characteristics and behavior.

The road to tailored adjuvant chemotherapy for all four non-pancreatic periampullary cancers: An international multimethod cohort study.

Background: Despite differences in tumour behaviour and characteristics between duodenal adenocarcinoma (DAC), the intestinal (AmpIT) and pancreatobiliary (AmpPB) subtype of ampullary adenocarcinoma and distal cholangiocarcinoma (dCCA), the effect of adjuvant chemotherapy (ACT) on these cancers, as well as the optimal ACT regimen, has not been comprehensively assessed. This study aims to assess the influence of tailored ACT on DAC, dCCA, AmpIT, and AmpPB.

Patients And Methods: Patients after pancreatoduodenectomy for non-pancreatic periampullary adenocarcinoma were identified and collected from 36 tertiary centres between 2010 - 2021.

Different Periampullary Types and Subtypes Leading to Different Perioperative Outcomes of Pancreatoduodenectomy: Reality and Not a Myth; An International Multicenter Cohort Study.

This international multicenter cohort study included 30 centers. Patients with duodenal adenocarcinoma (DAC), intestinal-type (AmpIT) and pancreatobiliary-type (AmpPB) ampullary adenocarcinoma, distal cholangiocarcinoma (dCCA), and pancreatic ductal adenocarcinoma (PDAC) were included. The primary outcome was 30-day or in-hospital mortality, and secondary outcomes were major morbidity (Clavien-Dindo 3b≥), clinically relevant post-operative pancreatic fistula (CR-POPF), and length of hospital stay (LOS).

Postoperative fluid therapy in enhanced recovery after surgery for pancreaticoduodenectomy.

Backgrounds/aims: Optimal intravenous fluid management during the perioperative period for patients undergoing pancreaticoduodenectomy (PD) within the framework of enhanced recovery after surgery (ERAS) is unclear. Studies have indicated that excessive total body salt and water can contribute to the development of oedema, leading to increased morbidity and extended hospital stays. This study aimed to assess the effects of an intravenous therapy regimen during postoperative day (POD) 0 to 2 in PD patients within ERAS.

Implementation of ERAS in pancreaticoduodenectomy in an Australian tertiary centre.

Background/objectives: Recent studies have demonstrated that enhanced recovery after surgery (ERAS) protocols in pancreaticoduodenectomy (PD) may decrease morbidity and length of stay. This study aimed to critically assess the implementation of ERAS in patients who have undergone a PD in a tertiary centre.

Methods: A retrospective cohort study of all patients who underwent a PD prior to ERAS, compared to following implementation were assessed.

Drain fluid amylase and lipase as a predictive factor of postoperative pancreatic fistula.

Background: Early detection of a postoperative pancreatic fistula (POPF) may improve outcomes after pancreaticoduodenectomy (PD). The aim was to assess the role of postoperative drain fluid amylase (DFA) and lipase (DFL) measurements as a predictive indicator in the development of POPF.

Methods: This retrospective cohort study included all PD procedures performed between 2009 and 2017 at Fremantle and Fiona Stanley Hospital in Western Australia.

The role of intraperitoneal ropivacaine in laparoscopic appendicectomy: a prospective, double-blinded randomized control Australian study.

Background: Currently, intraoperative use of local anaesthetic is not routinely given in all laparoscopic appendicectomies. Although its use has been widely studied in laparoscopic hernia repairs, gynaecological laparoscopy and laparoscopic cholecystectomies, there are no published trials of the use of intraperitoneal local anaesthetic during laparoscopic appendicectomy in the Australasian setting. The aim of this study was to determine whether the use of intraperitoneal ropivacaine during laparoscopic appendicectomy will reduce the amount of post-operative opiate analgesia used, abdominal pain, post-operative nausea or vomiting, shoulder tip pain and length of hospital stay.

Gastric outlet obstruction secondary to orbera intragastric balloon.

Intragastric balloons are used as a temporary restrictive method in obesity to induce weight loss. They are typically recommended when patients have mild obesity and have failed traditional first line treatments of diet, exercise and behaviour modification. We report a case of a 45-year-old female who presented with nausea, vomiting and abdominal pain two weeks following an uncomplicated insertion of an intragastric balloon.

Juvenile melanomas: Western Australian Melanoma Advisory Service experience.

Background/objectives: Juvenile melanoma (before 20 years of age) is a rare condition with poorly defined risk factors. We describe features of juvenile melanoma in Western Australia over the last two decades.

Method: A retrospective review of juvenile melanomas was conducted from prospectively maintained databases, reviewed for patients' characteristics, clinical information, histology, treatment, recurrence and survival data.

Cutaneous mucormycosis in an immunocompromised patient: a case report.

Mucormycosis is a rare and highly aggressive fungal infection, with a potential to reach its fulminant phase rapidly. We report a case of a 73-year-old immunocompromised vasculopath with cutaneous mucormycosis. The disease resulted in eventual death despite aggressive surgical debridement, revascularization of his limb and amphotericin-B.
