Artificial Intelligence and ChatGPT in Abdominopelvic Surgery: A Systematic Review of Applications and Impact.

BACKGROUND/AIM: The integration of AI and natural language processing technologies, such as ChatGPT, into surgical practice has shown promising potential in enhancing various aspects of abdominopelvic surgical procedures. This systematic review aims to comprehensively evaluate the current state of research on the applications and impact of artificial intelligence (AI) and ChatGPT in abdominopelvic surgery summarizing existing literature towards providing a comprehensive overview of the diverse applications, effectiveness, challenges, and future directions of these innovative technologies. MATERIALS AND METHODS: A systematic search of major electronic databases, including PubMed, Google Scholar, Cochrane Library, Web of Science, was conducted from October to November 2023, to identify relevant studies. Inclusion criteria encompassed studies that investigated the utilization of AI and ChatGPT in abdominopelvic surgical settings, including, but not limited to preoperative planning, intraoperative decision-making, postoperative care, and patient communication. RESULTS: Fourteen studies met the inclusion criteria and were included in this review. The majority of the studies were analysing ChatGPT's data output and decision making while two studies reported patient and general surgery resident perception of the tool applied to clinical practice. Most studies reported a high accuracy of ChatGPT in data output and decision-making process, however with an unforgettable number of errors. CONCLUSION: This systematic review contributes to the current understanding of the role of AI and ChatGPT in abdominopelvic surgery, providing insight into their applications and impact on clinical practice. The synthesis of available evidence will inform future research directions, clinical guidelines, and development of these technologies to optimize their potential benefits in enhancing surgical care within the abdominopelvic domain.

Complication of Gastric Cancer Surgery: A Single Centre Experience.

BACKGROUND/AIM: Gastric cancer surgery is still characterised by high morbidity and mortality. However, in 2018 an online platform, GASTRODATA has been proposed in Europe to standardize the recording of gastric surgery complications. The aim of the study was to present a single center experience regarding incidence and grading of acute postoperative complications in a population of patients treated surgically for gastric cancer on the basis of the gastrodata online platform. PATIENTS AND METHODS: The present study was a single center, observational, retrospective trial held in the General Surgery Unit of the Sant'Andrea Hospital of Rome. The study included 181 consecutive patients who underwent gastric surgical resection for cancer from May 2004 to December 2020 with curative R0 purpose. RESULTS: Thirty-three percent of patients reported at least one complication, while seventeen percent of the whole population reported a complication classified as at least grade 3 on the Clavien Dindo Classification. The most frequent complications were disorders of the respiratory system (13.3%), followed by bleeding (7.6%) and wound infections (6.2%). Deaths accounted for 3.7% of the population. CONCLUSION: A list of defined complications of gastrectomy, if systematically adopted in the Literature, could lead to a reduction in the wide variation of proposals for treatment and assessment. Objectively evaluating the impact of complications on outcomes can lead to quality improvement project proposals.

Overall Survival Following Anastomotic Leakage After Surgery for Carcinoma of the Esophagus and Gastroesophageal Junction: A Systematic Review.

The effect of anastomotic leakage, in patients who underwent surgery for carcinoma of the esophagus and gastroesophageal junction, on overall survival (OS) is a debated and controversial topic. The aim of this systematic review was to clarify the impact of anastomotic leakage on long-term survival of patients with esophageal cancer undergoing esophagectomy. A systematic literature review was carried out from 2000 to 2022. We chose articles reporting data from patients who underwent surgery for carcinoma of the esophagus and gastroesophageal junction. Data regarding 1-, 3- and 5-year OS were analyzed. Twenty studies met the inclusion criteria, yielding a total of 9,279 patients. Analyzing data from selected studies, anastomotic leakage was found to be associated with decreased OS in 5,456 cases while in the remaining 3,823 it had no impact on long term survival (p<0.05). However, this result did not emerge from the other studies considered in the systematic review. Anastomotic leakage is a severe postoperative complication, which seems to have an impact on overall survival. However, the topic remains debated and not supported by all case series included in this systematic review.

Postoperative Pancreatic Fistula: Is Minimally Invasive Surgery Better than Open? A Systematic Review and Meta-analysis.

BACKGROUND/AIM: Minimally invasive pancreaticoduodenectomy (PD) is gaining popularity. The aim of this study was to compare the incidence of postoperative pancreatic fistula (POPF) after minimally invasive versus open procedures. MATERIALS AND METHODS: Following the PRISMA statement, literature research was conducted focusing on papers comparing the incidence of POPF after open pancreaticoduodenectomy (OPD) versus minimally invasive pancreaticoduodenectomy (MIPD). RESULTS: Twenty-one papers were included in this meta-analysis, for a total of 4,448 patients. A total of 2,456 patients (55.2%) underwent OPD, while 1,992 (44.8%) underwent MIPD. Age, ASA score III patients, incidence of pancreatic ductal adenocarcinoma and duct diameter were significantly lower in the MIPD group. No statistically significant differences were found between the OPD and MIPD regarding the incidence of major complications (15.6% vs. 17.0%, respectively, p=0.55), mortality (3.7% vs. 2.4%, p=0.81), and POPF rate (14.3% vs. 12.9%, p=0.25). CONCLUSION: MIPD and OPD had comparable rates of postoperative complications, postoperative mortality, and POPF.

The Role of Surgery in the Treatment of Metachronous Liver Metastasis from Gastric Cancer: A Systematic Review.

BACKGROUND: Few data are available regarding metachronous liver metastases from gastric cancer. We aimed to identify data regarding the survival of these patients, considering the chosen treatment, with particular attention to the role of surgery. MATERIALS AND METHODS: A systematic review was carried out from 2000 to 2020. We chose articles reporting data from patients with metachronous liver metastases after curative gastrectomy. Data regarding 1-, 3- and 5-year overall survival were analyzed. RESULTS: Survival was improved in patients eligible for surgery (absence of extrahepatic non-curative factors and feasible complete macroscopic removal of liver deposits, i.e., H1 and H2 liver involvement, metastases less than 5 cm in size) when curative liver resection was performed, with a median overall survival of 24 months (vs. 3.13 in patients treated with chemotherapy). N Status, extent and maximum size of liver metastases, and hepatic surgical treatment were identified as independent prognostic factors. CONCLUSION: Selected patients with metachronous liver metastases from gastric cancer may benefit from multimodal 'aggressive' treatment. When hepatic involvement is limited (H1 and H2) and the size of metastases less than 5 cm, surgery was shown to increase survival.

Blunt Trauma Associated With Bilateral Diaphragmatic Rupture: A Case Report.

Background: A bilateral diaphragmatic rupture is a rare event that occurs in cases of blunt thoracic-abdominal trauma. Case Presentation: We report the case of a 56-year-old female patient with pelvic fracture and second-stage bilateral rupture of the diaphragm due to a car accident. After a chest and abdominal contrast-enhanced computed tomography (CT) scan, the patient underwent emergency suturing of the left hemidiaphragm. On postoperative day (POD) 4, a CT scan performed due to the sudden onset of dyspnea revealed rupture of the right hemidiaphragm, which was not detected on the preoperative CT scan. On POD 9, the right hemidiaphragm was repaired with mesh during a right thoracotomy. The patient recovered 14 days after surgery. However, the postoperative course was complicated by an asymptomatic COVID-19 infection that significantly delayed her discharge from the hospital. Conclusions: Difficulties in preoperative diagnosis and treatment, together with the lack of data in the literature, make this type of trauma a challenge for all acute care and general surgeons.
