major abdominal surgery

BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is traditionally a maximally invasive operation with a large abdominal incision and multi-visceral resections. However, to minimize abdominal wall morbidity and improve functional recovery, some centres have adopted a minimally invasive (MI) approach in select cases. The primary aim of this systematic review and meta-analysis was to assess the evidence for safety and patient selection for minimally invasive approaches to CRS and HIPEC with curative intent...

Congenital diaphragmatic hernia (CDH) is a major congenital anomaly, resulting from the herniation of abdominal contents into the thoracic cavity, thereby impeding the proper development of the lungs and pulmonary vasculature. CDH severity correlates with a spectrum of pulmonary hypoplasia, pulmonary hypertension (PHT), and cardiac dysfunction, constituting the pathophysiological triad of this complex condition. The accurate diagnosis and effective management of PHT and cardiac dysfunction is pivotal to optimizing patient outcomes...

Primary segmental omental torsion (PSOT) is a very rare cause of acute abdominal pain, and it may often imitate the clinical picture of acute appendicitis. In instances of acute abdominal pain without anorexia, nausea, and vomiting, omental torsion should be included in the differential diagnosis. Any misdiagnosis may lead to major complications such as intraabdominal abscesses and adhesions. A 63-year-old overweight man with a body mass index (BMI) of 41 Kg/m2 presented to the emergency department on a remote island with acute abdominal pain...

INTRODUCTION: Anastomotic leakage (AL) is defined as the failure of complete healing or disruption of the anastomosis subsequent to rectal cancer surgery, resulting in the extravasation of intestinal contents into the intra-abdominal or pelvic cavity. It is a serious complication of rectal cancer surgery, accounting for a considerable increase in morbidity and mortality. The use of fluorescence imaging technology in surgery allows surgeons to better evaluate blood perfusion. However, the conclusions of some existing studies are not consistent, so a consensus on whether the near-infrared indocyanine green (NIR-ICG) imaging system can reduce the incidence of AL is needed...

OBJECTIVE: To explore the safety and feasibility of the Da Vinci® Single-Port (SP) platform in Robotic-Assisted Radical Prostatectomy (SP-RARP), aiming to provide a viable option for patients with surgical and medical complexities that might otherwise limit their access to common minimally invasive technique. METHODS: Data from 60 medically and surgically highly complex patients undergoing SP-RARP between December 2018 and December 2023 were analyzed. Variables included patient characteristics, surgical history, intraoperative and postoperative outcomes...

INTRODUCTION: Continuous ambulatory peritoneal dialysis is an important modality of renal replacement therapy in children. Catheter dysfunction (commonly obstruction) is a major cause of morbidity and is a significant concern that hampers renal replacement therapy. As omentum is a significant cause of obstruction, some recommend routine omentectomy during insertion of the peritoneal dialysis catheter. Omentopexy rather than omentectomy has been described in adults to spare the omentum as it may be needed as a spare part in many conditions...

Abdominal wall endometrioma (AWE) results from endometrial-like tissue implants in the abdominal wall after uterine surgery. While the diagnosis can be challenging, an abdominal mass at the site of a previous incision accompanied by cyclical pain and enlargement correlating with menstruation is highly suspicious. Excision is indicated for symptomatic relief as well as the probability of malignant transformation. Because signs and symptoms are similar to other soft tissue lesions, general surgeons are sought out for excision and thus encounter the majority of AWE cases...

Meckel's diverticula are one of the most common gastrointestinal anomalies, yet mesodiverticular bands are rare. The treatment of these bands commonly requires surgery. A healthy patient in his 20s presented to the emergency department with a 1 day history of acute onset abdominal pain. Computed tomography imaging was consistent with volvulus of the large intestine. In the operating room, the patient was noted to have a band between the ileal mesentery and tip of a Meckel's diverticulum, consistent with a mesodivertiular band, through which cecum had volvulized...

BACKGROUND: Although laparoscopy has demonstrated growing applications for either primary colorectal resections or reoperations, no standardized criteria for implementing laparoscopy in revisional surgery have been reported. This study analyzes a single-center series of major complications after laparoscopic colorectal surgery, undergoing laparoscopic (LR), or open reoperations in compliance with a hemodynamics-based institutional management. METHODS: This study retrospectively analyzes a series of consecutive patients who primarily underwent either laparoscopic left colectomy or low anterior resection in a tertiary referral center between 2016 and 2021...

BACKGROUND: Dynamic fluctuations of arterial blood pressure known as blood pressure variability (BPV) may have short and long-term undesirable consequences. During surgical procedures blood pressure is usually measured in equal intervals allowing to assess its intraoperative variability, which significance for peri and post-operative period is still under debate. Lidocaine has positive cardiovascular effects, which may go beyond its antiarrhythmic activity. The aim of the study was to verify whether the use of intravenous lidocaine may affect intraoperative BPV in patients undergoing major vascular procedures...

Beckwith-Wiedemann syndrome (BWS) is a rare genomic imprinting disorder that affects multiple systems. Major features can manifest as large birth weight, anterior abdominal wall defects, macroglossia, hyperinsulinism, organomegaly hemihypertrophy, and renal abnormalities. Characteristic facies manifested as midface hypoplasia, infraorbital creases, facial nevus simplex, and anterior linear ear lobe creases/posterior helical ear pits, with a predisposition to tumor development. This case report describes a Saudi infant born at 38+5 weeks gestation via elective cesarean section to a 33-year-old G3P2+0 mother, with a family history of type 1 diabetes and Down syndrome...

Morgagni hernias may range from asymptomatic incidental findings to surgical emergencies. An abdominal approach is ideal in the majority of cases, although surgeons should understand alternatives for repair.

INTRODUCTION: Heterotopic ossification (HO) develops when bone formation appears in soft tissues, usually after an injury or major surgery. Timely and accurately diagnosing of this rare event is essential due to the possibility of misdiagnosis as a maintained foreign body, infection, incisional neoplastic recurrence, and metastatic or primary neoplasms. CASE PRESENTATION: In this study, we present a 57-year-old man who was operated for peritonitis due to perforated appendicitis, and an asymptomatic HO was accidentally found on an incisional line of previous open prostatectomy about 5 years earlier due to benign prostatic hyperplasia...

PURPOSE: Paraoesophageal hernias (PEH) are associated with a high complication rate and often occur in elderly and fragile patients. Surgical gastropexy without fundoplication is an accepted alternative procedure; however, outcomes and functional results are rarely described. Our study aims to evaluate short-term outcomes and the long-term quality of life after gastropexy as treatment for PEH. METHODS: Single center cohort analysis of all consecutive patients who underwent gastropexy for PEH without fundoplication...

OBJECTIVE: Vascular surgery registries report on procedures and outcomes to promote patient safety and drive quality improvement. International registries have significantly contributed to the VASCUNET collaborative abdominal aortic aneurysm (AAA) outcome projects. This scoping review aimed to outline the national registries in vascular surgery that currently participate in the VASCUNET collaborative AAA projects. METHODS: A scoping review of all published VASCUNET AAA studies and validation reports between 1997 and 2024 was undertaken...

OBJECTIVE: Fenestrated or branched endovascular repairs (f/bEVAR) are valuable treatments in patients with chronic post-dissection thoraco-abdominal aneurysms (PD-TAAA). This study aimed to analyse early and follow up outcomes of f/bEVAR. DESIGN: Thirty day and follow up outcomes of consecutive patients with PD-TAAA treated with f/bEVAR in a tertiary centre over 8 years were retrospectively analysed. METHODS: All patients presenting with PD-TAAA and managed with f/bEVAR, were eligible...

Extrahepatic biliary tract obstruction (EHBO) is uncommonly encountered in cats. Surgical treatment aims to decompress the biliary tract and insure bile duct patency. In veterinary medicine, cholecystotomy is not widely used in practice. The objective was to describe the use of cholecystotomy, retrograde hydropulsion of choleliths, and choledochal stenting to remove choleliths from the extrahepatic biliary tract back in the gallbladder. Three adult domestic shorthair cats were presented with anorexia, lethargy, and vomiting...

Focused perioperative nutrition strategies have proven benefits on the outcomes for patients undergoing major abdominal surgery. In this brief article, we will review these strategies and the evidence to support them with a focus on gastrointestinal anastomotic healing. We will elaborate the risks and benefits of enteral feeds, immune- and metabolic-modulating formulas, prebiotics and probiotics, and prehabilitation in preparation for surgery. Additionally, we will discuss the role of fish oils (eicosapentaenoic acid and docosahexaenoic acid) in the surgical patient and new data on specialized proresolving mediators in inflammation resolution...

PURPOSE: Resection of sacral neoplasms such as chordoma and chondrosarcoma with subsequent reconstruction of large soft tissue defects is a complex multidisciplinary process. Radiotherapy and prior abdominal surgery play a role in reconstructive planning; however, there is no consensus on how to maximize outcomes. In this study, we present our institution's experience with the reconstructive surgical management of this unique patient population. METHODS: We conducted a retrospective review of patients who underwent reconstruction after resection of primary or recurrent pelvic chordoma or chondrosarcoma between 2002 and 2019...
