Anastomotic leakage is a potentially severe complication occurring after colorectal surgery and can lead to increased morbidity and mortality, permanent stoma formation, and cancer recurrence. Multiple risk factors for anastomotic leak have been identified, and these can allow for better prevention and an earlier diagnosis of this significant complication. There are nonmodifiable factors such as male gender, comorbidities and distance of tumor from anal verge, and modifiable risk factors, including smoking and alcohol consumption, obesity, preoperative radiotherapy and preoperative use of steroids or non-steroidal anti-inflammatory drugs. Perioperative blood transfusion was shown to be an important risk factor for anastomotic failure. Recent studies on the laparoscopic approach in colorectal surgery found no statistical difference in anastomotic leakage rate compared with open surgery. A diverting stoma at the time of primary surgery does not appear to reduce the leak rate but may reduce its clinical consequences and the need for additional surgery if anastomotic leakage does occur. It is still debatable if preoperative bowel preparation should be used, especially for left colon and rectal resections, but studies have shown similar incidence of postoperative leak rate.

Abdominal compartment syndrome (ACS) represents a severe complication of acute pancreatitis (AP), resulting from an acute and sustained increase in abdominal pressure >20 mmHg, in association with new organ dysfunction. The harmful effect of high intra-abdominal pressure on regional and global perfusion results in significant multiple organ failure and is associated with increased morbidity and mortality. There are several deleterious consequences of elevated intra-abdominal pressure on end-organ function, including respiratory, cardiovascular, gastrointestinal, neurologic, and renal effects. It is estimated that about 15% of patients with severe AP develop intra-abdominal hypertension or ACS, with a mortality rate around 50%. The treatment of abdominal compartment syndrome in acute pancreatitis begins with medical intervention and percutaneous drainage, where possible. Abdominal compartment syndrome unresponsive to conservatory treatment requires immediate surgical decompression, along with vacuum-assisted closure therapy techniques, followed by early abdominal fascia closure.

Acute necrotizing pancreatitis (ANP), characterized by necrosis of pancreatic and/or peripancreatic tissues, is a potentially severe and life-threatening complication of acute pancreatitis, exhibiting a considerable mortality rate, particularly in the presence of infection, with rates ascending to 20–30%. Contrast-enhanced computed tomography is the definitive diagnostic standard, although treatment is determined by illness severity and the presence of secondary infection. The management of this condition has undergone considerable evolution, transitioning from initial surgical intervention to a more progressive, minimally invasive strategy. Initial management emphasizes aggressive fluid resuscitation, nutritional support, and monitoring of organ dysfunction. Infected necrosis is a critical factor influencing prognosis and requires intervention, typically starting with percutaneous drainage or endoscopic necrosectomy prior to evaluating surgical debridement. Recent advancements, such as the implementation of endoscopic and minimally invasive techniques, have enhanced outcomes by decreasing morbidity and mortality linked to open surgery. Despite these advancements, optimal treatment strategies are patient-specific and necessitate a multidisciplinary approach. Additional research is necessary to enhance guidelines and optimize patient outcomes.

Background: The optimal management of patients with acute pancreatitis is directly related to the early detection of the mild, moderate, or severe forms of the disease, which remains a continuous challenge despite the availability of various severity scores. The aim of this study was to identify prognostic factors with the highest predictive value specific to the local patients and elaborate the score to identify the severe cases. Materials and Methods: A retrospective observational cohort study included 172 patients diagnosed with acute pancreatitis. Personal, clinical, laboratory, and imaging factors and their influence on the severity of acute pancreatitis were evaluated. Results: Etiology nonA-nonB (any etiology except unique alcoholic or biliary etiology), presence of diabetes mellitus, the pain Visual Analogue Scale (VAS), White Blood Cells (WBCs), and CRP (C-reactive protein) levels were found to be directly associated with the severity of acute pancreatitis (AP). Prediction scores were calculated to estimate disease severity using the following regression equations: Prediction Acute Pancreatitis Severity (PAPS) score I = 1.237 + 0.144 × nonA-nonB (0 = no, 1 = yes) + 0.001 × WBC1 + 0.027 × VAS0 and PAPS score II = 1.189 + 0.001 × CRP (mg/L) + 0.135 × nonA-nonB etiology (0 = no, 1 = yes) + 0.025 × VAS0 − 0.047 × CA1. The PAPS Score II demonstrated the best performance. At a cut-off value of 1.248, the score had 80% sensitivity, 80.9% specificity, a positive predictive value (PPV) of 28.6%, a negative predictive value (NPV) of 97.7%, and an accuracy of 80.8%. For a cut-off value of 221.5 mg/L, the accuracy of CRP was 81.4% for predicting severe AP. Conclusions: The PAPS score II is an easy-to-use, fast, and affordable score for determining cases of severe disease for patients diagnosed with AP.

Background and Objectives: This study aimed to investigate the potential risk factors for severe postoperative complications after oncologic right colectomy. Materials and Methods: All consecutive patients with right colon cancer who underwent right colectomy in our department between 2016 and 2021 were retrospectively included in this study. The Clavien–Dindo grading system was used to evaluate postoperative complications. Univariate and multivariate logistic regression analyses were used to investigate risk factors for postoperative severe complications. Results: Of the 144 patients, there were 69 males and 75 females, with a median age of 69 (IQR 60–78). Postoperative morbidity and mortality rates were 41.7% (60 patients) and 11.1% (16 patients), respectively. The anastomotic leak rate was 5.3% (7 patients). Severe postoperative complications (Clavien–Dindo grades III–V) were present in 20 patients (13.9%). Univariate analysis showed the following as risk factors for postoperative severe complications: Charlson score, lack of mechanical bowel preparation, level of preoperative proteins, blood transfusions, and degree of urgency (elective/emergency right colectomy). In the logistic binary regression, the Charlson score (OR = 1.931, 95% CI = 1.077–3.463, p = 0.025) and preoperative protein level (OR = 0.049, 95% CI = 0.006–0.433, p = 0.007) were found to be independent risk factors for postoperative severe complications. Conclusions: Severe complications after oncologic right colectomy are associated with a low preoperative protein level and a higher Charlson comorbidity index.

Background: The aim of this study was to investigate the impact of postoperative complications on the long-term outcomes of patients who had undergone simultaneous resection (SR) of colorectal cancer and synchronous liver metastases (SCLMs). Methods: We conducted a single-institution survival cohort study in patients with SR, collecting clinical, pathological, and postoperative complication data. The impact of these variables on overall survival (OS) and disease-free survival (DFS) was compared by log rank test. Multivariate Cox regression analysis identified independent prognostic factors. Results: Out of 243 patients, 122 (50.2%) developed postoperative complications: 54 (22.2%) major complications (Clavien–Dindo grade III–V), 86 (35.3%) septic complications, 59 (24.2%) hepatic complications. Median comprehensive complication index (CCI) was 8.70. Twelve (4.9%) patients died postoperatively. The 3- and 5-year OS and DFS rates were 60.7%, 39.5% and 28%, 21.5%, respectively. Neither overall postoperative complications nor major and septic complications or CCI had a significant impact on OS or DFS. Multivariate analysis identified the N2 stage as an independent prognostic of poor OS, while N2 stage and four or more SCLMs were independent predictors for poor DFS. Conclusion: N2 stage and four or more SCLMs impacted OS and/or DFS, while CCI, presence, type, or grade of postoperative complications had no significant impact on long-term outcomes.
