A comparison between real-time intraoperative voice dictation and the operative report in laparoscopic cholecystectomy: a multicenter prospective observational study.

Purpose: The current operative report often inadequately reflects events occurring during laparoscopic cholecystectomy (LC). The addition of intraoperative video recording to the operative report has already proven to add important information. It was hypothesized that real-time intraoperative voice dictation (RIVD) can provide an equal or more complete overview of the operative procedure compared to the narrative operative report (NR) produced postoperatively.

The incidence of extraction site incisional hernia after minimally invasive colorectal surgery: a systematic review and meta-analysis.

Aim: Minimally invasive colorectal surgery reduces surgical trauma with better preservation of abdominal wall integrity, but the extraction site is still at risk of incisional hernia (IH). The aim of this study was to determine pooled incidence of IH for each type of extraction site and to compare rates of IH after midline, nonmidline and Pfannenstiel extraction.

Method: A systematic review and meta-analysis was conducted using the PRISMA guidelines.

Monocyte response after colorectal surgery: A prospective cohort study.

Background: Tumor resection is the common approach in patients with colorectal malignancy. Profound insight into inflammatory changes that accompany the normal post-operative stress response will establish reference parameters useful for identification of putative complications. Alterations in circulating monocytes might be indicative as these cells are considered to be the most responsive leukocytes to trauma.

Favorable Outcomes After Retro-Rectus (Rives-Stoppa) Mesh Repair as Treatment for Noncomplex Ventral Abdominal Wall Hernia, a Systematic Review and Meta-analysis.

Objective: To assess prevalence of hernia recurrence, surgical site infection (SSI), seroma, serious complications, and mortality after retro-rectus repair.

Summary Background Data: Ventral abdominal wall hernia is a common problem, tied to increasing frailty and obesity of patients undergoing surgery. For noncomplex ventral hernia, retro-rectus (Rives-Stoppa) repair is considered the gold standard treatment.

C-reactive protein (CRP) trajectory as a predictor of anastomotic leakage after rectal cancer resection: A multicentre cohort study.

Aim: This study aimed to identify whether CRP-trajectory measurement, including increase in CRP-level of 50 mg/l per day, is an accurate predictor of anastomotic leakage (AL) in patients undergoing resection for rectal cancer.

Methods: A prospective multicentre database was used. CRP was recorded on the first three postoperative days.

Objective: The purpose of this review is to evaluate the relevance of vascular calcification as a potential risk factor for anastomotic leakage in colorectal surgery.

Method: The Embase, Medline, PubMed, and Cochrane databases and Google Scholar were systematically searched. Studies that assessed calcification of the aorta-iliac trajectory in patients who underwent colorectal surgery were included.

Medialization after combined anterior and posterior component separation in giant incisional hernia surgery, an anatomical study.

Background: To obtain tension-free closure for giant incisional hernia repair, anterior or posterior component separation is often performed. In patients with an extreme diameter hernia, anterior component separation and posterior component separation may be combined. The aim of this study was to assess the additional medialization after simultaneous anterior component separation and posterior component separation.

Outcomes of Incisional Hernia Repair Surgery After Multiple Re-recurrences: A Propensity Score Matched Analysis.

Background: Patients with a re-recurrent hernia may account for up to 20% of all incisional hernia (IH) patients. IH repair in this population may be complex due to an altered anatomical and biological situation as a result of previous procedures and outcomes of IH repair in this population have not been thoroughly assessed. This study aims to assess outcomes of IH repair by dedicated hernia surgeons in patients who have already had two or more re-recurrences.

Arterial calcification is a risk factor for anastomotic leakage after esophagectomy: A systematic review and meta-analysis.

Background: Leakage of the esophago-gastrostomy after esophagectomy with gastric tube reconstruction is a serious complication. Anastomotic leakage occurs in up to 20% of patients and a compromised perfusion of the gastric tube is thought to play an important role. This meta-analysis aimed to investigate whether arterial calcification is a risk factor for anastomotic leakage in esophageal surgery.

Matrix metalloproteinase-9 in relation to patients with complications after colorectal surgery: a systematic review.

Purpose: Anastomotic leakage (AL) is the most severe complication following colorectal resection and is associated with increased mortality. The main group of enzymes responsible for collagen and protein degradation in the extracellular matrix is matrix metalloproteinases. The literature is conflicting regarding anastomotic leakage and the degradation of extracellular collagen by matrix metalloproteinase-9 (MMP-9).

Functional outcomes in symptomatic versus asymptomatic patients undergoing incisional hernia repair: Replacing one problem with another? A prospective cohort study in 1312 patients.

Background: Incisional hernias can be associated with pain or discomfort. Surgical repair especially mesh reinforcement, may likewise induce pain. The primary objective was to assess the incidence of pain after hernia repair in patients with and without pre-operative pain or discomfort.

Association of Video Completed by Audio in Laparoscopic Cholecystectomy With Improvements in Operative Reporting.

Importance: All events that transpire during laparoscopic cholecystectomy (LC) cannot be adequately reproduced in the operative note. Video recording is already known to add important information regarding this operation.

Objective: It is hypothesized that additional audio recordings can provide an even better procedural understanding by capturing the surgeons' considerations.

Comparison of different modalities for the diagnosis of parastomal hernia: a systematic review.

Purpose: Parastomal hernia (PSH) is a common complication following stoma formation. The incidence of PSH varies widely due to several factors including differences in diagnostic modality, observer, definition, and classification used for diagnosing PSH. The aim of this systematic review was to evaluate the diagnostic accuracy of the modalities used to identify PSH.

Zinc-Impregnated Mesh for Abdominal Wall Repair Reduces Infection in a Rat Model of Peritonitis.

Background: The objective of this study was to assess whether a zinc-impregnated polypropylene mesh (ZnMesh) has better antibacterial properties in a contaminated environment compared with a regular polypropylene mesh.

Materials And Methods: Thirty-eight Wistar Han rats underwent cecal ligation and puncture to induce peritonitis 24 h before implantation of an intraperitoneal ZnMesh or a regular polypropylene mesh. Primary outcome was the number of colony forming units (CFU) per sample (mesh and abdominal wall).

Outcomes After Elective Colorectal Surgery by 2 Surgeons Versus 1 Surgeon in a Low-Volume Hospital.

Improved patient outcomes after colorectal surgery in high-volume hospitals are leading to centralization of colorectal surgery. However, it is desirable to strive for optimal quality of colorectal surgery in low-volume hospitals. This study aimed to assess the effect of the number of surgeons involved in the surgical procedure on patient outcomes in a low-volume hospital.

Comparison of Systematic Video Documentation With Narrative Operative Report in Colorectal Cancer Surgery.

Importance: Despite ongoing advances in the field of colorectal surgery, the quality of surgical treatment is still variable. As an intrinsic part of surgical quality, the technical information regarding the surgical procedure is reflected only by the narrative operative report (NR), which has been found to be subjective and regularly omits important information.

Objective: To investigate systematic video recording (SVR) as a potential improvement in quality and safety with regard to important information in colorectal cancer surgery.

Different Risk Factors for Early and Late Colorectal Anastomotic Leakage in a Nationwide Audit.

Background: Anastomotic leakage remains a major complication after surgery for colorectal carcinoma, but its origin is still unknown. Our hypothesis was that early anastomotic leakage is mostly related to technical failure of the anastomosis, and that late anastomotic leakage is mostly related to healing deficiencies.

Objective: The aim of this study was to assess differences in risk factors for early and late anastomotic leakage.

Blockade of LAG3 enhances responses of tumor-infiltrating T cells in mismatch repair-proficient liver metastases of colorectal cancer.

: Liver metastasis develops in >50% of patients with colorectal cancer (CRC), and is a leading cause of CRC-related mortality. We aimed to identify which inhibitory immune checkpoint pathways can be targeted to enhance functionality of intra-tumoral T-cells in mismatch repair-proficient liver metastases of colorectal cancer (LM-CRC). : Intra-tumoral expression of multiple inhibitory molecules was compared among mismatch repair-proficient LM-CRC, peritoneal metastases of colorectal cancer (PM-CRC) and primary CRC.

The effect of age on anastomotic leakage in colorectal cancer surgery: A population-based study.

Background: The aim of this study was to investigate the effect of age on CAL and its associated mortality.

Methods: Data were derived from the Dutch ColoRectal Audit. All patients undergoing resection for colorectal cancer in the Netherlands between January 2011 and December 2016 were included.

Anastomotic Leakage and Interval between Preoperative Short-Course Radiotherapy and Operation for Rectal Cancer.

Background: Short-course preoperative radiotherapy is indicated in patients with resectable rectal cancer to control local recurrence. Although no clear evidence is available, short-course radiotherapy with operation within a week is common practice. The aim of this study was to investigate the impact of timing of operation for rectal cancer after short-course radiotherapy on anastomotic leakage.

Severity of Diverticulitis Does Not Influence Abdominal Complaints during Long-Term Follow-Up.

Background: Diverticulitis can lead to localized or generalized peritonitis and consequently induce abdominal adhesion formation. If adhesions would lead to abdominal complaints, it might be expected that these would be more prominent after operation for perforated diverticulitis with peritonitis than after elective sigmoid resection.

Aims: The primary outcome of the study was the incidence of abdominal complaints in the long-term after acute and elective surgery for diverticulitis.

Oxygen therapies and their effects on wound healing.

Oxygen is an important factor for wound healing. Although several different therapies investigated the use of oxygen to aid wound healing, the results of these studies are not unequivocal. This systematic review summarizes the clinical and experimental studies regarding different oxygen therapies for promoting wound healing, and evaluates the outcomes according the methodological details.

Nicotine chewing gum for the prevention of postoperative ileus after colorectal surgery: a multicenter, double-blind, randomised, controlled pilot study.

Purpose: When postoperative ileus is not resolved after 5 days or recurs after resolution, prolonged POI (PPOI) is diagnosed. PPOI increases discomfort, morbidity and hospitalisation length, and is mainly caused by an inflammatory response following intestinal manipulation. This response can be weakened by targeting the cholinergic anti-inflammatory pathway, with nicotine as essential regulator.

Reinforcement of the colon anastomosis with cyanoacrylate glue: a porcine model.

Background: Previous experimental studies on cyanoacrylate (CA) glue for the prevention of colorectal anastomotic leakage (AL) have shown promising results. The aim of this study was to investigate the effect of CA in prevention of leakage in a porcine model of ischemic colorectal AL.

Methods: Twenty-four animals were divided into four groups of six: (1)ischemic anastomosis with sufficient suture (ISCH), (2)ischemic anastomosis with sufficient suture and CA reinforcement (CA-ISCH), (3)ischemic anastomosis with insufficient suture (ISCH-AI), and (4)ischemic anastomosis with insufficient suture and CA reinforcement (CA-ISCH-AI).

Cytokines as Early Markers of Colorectal Anastomotic Leakage: A Systematic Review and Meta-Analysis.

Purpose. Colorectal anastomotic leakage (CAL) is one of the most severe complications after colorectal surgery. This meta-analysis evaluates whether systemic or peritoneal inflammatory cytokines may contribute to early detection of CAL.
