Background And Aim: Postoperative pancreatic fistula (POPF) remains a significant challenge following pancreatoduodenectomy (PD), contributing to morbidity and mortality. Various risk assessment models have been established to predict the likelihood of POPF. An updated alternate fistula risk score (ua-FRS) has been recently refined and validated within European cohorts.

Background: Clinically relevant-postoperative pancreatic fistula (CR-POPF) is one of the dreaded complications of pancreatoduodenectomy. Vascularity of the stump of the pancreas during pancreatico-enteric anastomosis is considered one of the major determinants of POPF. Indocyanine green (ICG) is one of the modality for vascular assessment; hence, we aimed to evaluate the role of ICG fluorescence imaging to assess the vascularity of the pancreatic stump during pancreatoduodenectomy.

Unlabelled: All coronaviruses (CoVs) encode for a conserved macrodomain (Mac1) located in non-structural protein 3. Mac1 is an ADP-ribosylhydrolase that binds and hydrolyzes mono-ADP-ribose from target proteins. Previous work has shown that Mac1 is important for virus replication and pathogenesis.

Article Synopsis
  • - Achalasia cardia is a rare disorder affecting the lower esophageal sphincter, making it challenging to diagnose due to varying symptoms.
  • - The case series details three patients: an 18-year-old male and two females (37 and 47 years old) who faced different diagnostic experiences, from a prolonged journey to a quick diagnosis using barium swallow.
  • - All patients were successfully treated with laparoscopic Heller's myotomy and anterior Dor's fundoplication, emphasizing the need for early recognition and effective surgical options.

Introduction The Nutritional Risk Screening 2002 (NRS 2002) is a reliable tool for assessing patients' nutritional status and for identifying those who may benefit from nutritional support before undergoing surgery. However, its application and correlation with post-operative outcomes for Nepalese patients undergoing gastrointestinal and hepatopancreatobiliary oncosurgeries remain unexplored. The objective of this study was to correlate the NRS 2002's nutritional risk with post-operative complications classified by the Clavien-Dindo Classification.

Introduction: The comprehensive complication index (CCI) has emerged as a new tool for reporting postoperative complications. The aim of this study is to evaluate and compare the efficacy of CCI and Clavien-Dindo Classification (CDC) in measuring postoperative outcomes in patients undergoing hepato-pancreato-biliary (HPB) surgery.

Materials And Methods: In this single-centered, prospective, comparative study conducted between January 2022 and March 2023, 1240 patients underwent HPB surgery, including laparoscopic cholecystectomies and complex HPB surgery.

The ongoing COVID-19 pandemic caused by SARS-CoV-2 is associated with acute respiratory distress syndrome (ARDS) and fatal pneumonia. Excessive inflammation caused by SARS-CoV-2 is the key driver of ARDS and lethal disease. Several FDA-approved drugs that suppress virus replication are in clinical use.

Introduction: Abdominal scars result from various open abdominal surgeries. Laparoscopic surgery in previous open abdominal surgery possesses various challenges to the surgeon like gaining access to the abdominal cavity, and difficulty in dissection due to dense adhesions from previous surgeries for various intraabdominal pathologies. This study aimed to find out the prevalence of previous abdominal scars among patients undergoing laparoscopic cholecystectomy in a tertiary care centre.

Several coronavirus (CoV) encoded proteins are being evaluated as targets for antiviral therapies for COVID-19. Included in these drug targets is the conserved macrodomain, or Mac1, an ADP-ribosylhydrolase and ADP-ribose binding protein encoded as a small domain at the N terminus of nonstructural protein 3. Utilizing point mutant recombinant viruses, Mac1 was shown to be critical for both murine hepatitis virus (MHV) and severe acute respiratory syndrome (SARS)-CoV virulence.

Unlabelled: Laparoscopic liver resection is taking stride in slowly replacing open surgeries for various hepatic pathologies in many developed countries. However, due to high cost and lack of expertise, there are only a handful of centres in the low-medium income countries who perform advanced laparoscopic liver resections regularly. In this study, a prospective analysis was carried out to assess and report the outcomes of laparoscopic anatomical segmentectomy (LAS) from a single centre in Nepal.

SARS-CoV-2-induced impaired antiviral and excessive inflammatory responses cause fatal pneumonia. However, the key pattern recognition receptors that elicit effective antiviral and lethal inflammatory responses are not well defined. CoVs possess single-stranded RNA (ssRNA) genome that is abundantly produced during infection and stimulates both antiviral interferon (IFN) and inflammatory cytokine/ chemokine responses.

Introduction: Blunt abdominal trauma bears significant morbidity and mortality worldwide and needs careful evaluation and management for a better outcome, where the resources are limited and the impact of the financial burden is very important. Previously, many cases used to be managed with operative procedures, and now the trend has been shifting to non-operative management. This study aimed to determine the prevalence of blunt abdominal trauma among patients admitted to the Department of Surgery of a tertiary care centre.

Introduction: Rheumatic heart disease (RHD), is a common cause of mitral stenosis (MS) in developing nations. As per current recommendation, Percutaneous Transvenous Mitral Commissurotomy (PTMC) is advised as a Class IA (I-Class Of Recommendation, COR; A-Level Of Evidence, LOE) indication in patients with symptomatic severe mitral stenosis. We aim to examine the clinical profile and in-hospital results of PTMC for mitral stenosis.

Effective broad-spectrum antivirals are critical to prevent and control emerging human coronavirus (hCoV) infections. Despite considerable progress made toward identifying and evaluating several synthetic broad-spectrum antivirals against hCoV infections, a narrow therapeutic window has limited their success. Enhancing the endogenous interferon (IFN) and IFN-stimulated gene (ISG) response is another antiviral strategy that has been known for decades.

A weakening or defect in posterolateral abdominal wall can lead to development of lumbar hernia. These defects are particularly common in Petit's inferior triangle or Grynfeltt-Lesshaft superior triangle. There are very few cases of primary lumbar hernias that have been described in literature till date.

Introduction: Pancreatoduodenectomy with vascular resection is performed in locally advanced periampullary malignancies. In our practice, early oral feeding is initiated in patients undergoing pancreatoduodenectomy. This study aims to find the prevalence of early oral feeding with vascular resection among patients undergoing pancreatoduodenectomy.

Uterocutaneous fistula is a rare complication that occurs after cesarean section and other pelvic operations. Here we report a case of a 27 years woman presented to our department with a mass and pus-like discharge coming from her previous Pfannenstiel incision for 1 month. The definitive treatment of such cases is hysterectomy but the case was managed by fistulectomy along with gonadotropin-releasing hormone agonist.

Introduction And Importance: Gallstone ileus is caused by an impaction of one or more gallstones within the gastrointestinal tract, leading to mechanical intestinal obstruction. It is a rare complication of cholelithiasis leading to the formation of a cholecystoenteric fistula and is associated with high mortality rates. We report a case of atypical subacute small bowel obstruction due to gallstone ileus.

Article Synopsis
  • Different transplant centers have varying practices for ligating natural portosystemic shunts during liver transplants to avoid complications like portal steal phenomenon, but clear guidelines are lacking.
  • A study involving 89 cirrhotic patients revealed no significant differences in early graft dysfunction or portal venous complications between those who underwent shunt ligation and those who didn't, despite more overall complications in the non-ligated group.
  • The findings suggest that shunt ligation might not be essential in living donor liver transplants if there is sufficient portal flow and good graft quality.
