Surgical Laparoscopy, Endoscopy & Percutaneous Techniques

BACKGROUND: The objective of this study was to analyze device safety and clinical outcomes of inguinal hernia repair with the GORE SYNECOR Intraperitoneal Biomaterial device, a hybrid composite mesh. METHODS: This retrospective case review analyzed device/procedure endpoints beyond 1 year in patients treated for inguinal hernia repair with the device. Three objectives were evaluated: procedural endpoint-incidence through 30 days of surgical site infection, surgical site occurrence (SSO), ileus, readmission, reoperation, and death; device endpoint-serious device incidence of mesh erosion, infection, excision/removal, exposure, migration, shrinkage, device-related bowel obstruction and fistula, and hernia recurrence through 12 months; and patient-reported outcomes of the bulge, physical symptoms, and pain...

BACKGROUND: Our institution (UFHJ) meets the criteria of both a large, specialized medical center (LSCMC) and a safety-net hospital (AEH). Our aim is to compare pancreatectomy outcomes at UFHJ against other LSCMCs, AEHs, and against institutions that meet criteria for both LSCMC and AEH. In addition, we sought to evaluate differences between LSCMCs and AEHs. MATERIALS AND METHODS: Pancreatectomies for pancreatic cancer were queried from the Vizient Clinical Data Base (2018 to 2020)...

BACKGROUND: Gastrojejunal (GJ) anastomotic stenosis is a well-described complication after Roux-en-Y gastric bypass (RYGB); however, its impact on weight loss outcomes is not well elucidated. METHODS: We performed a retrospective cohort study of adult patients who underwent RYGB at our institution between 2008 and 2020. Propensity score matching was used to match 30 patients who developed GJ stenosis within the first 30 days post-RYGB with 120 control patients who did not develop this outcome...

INTRODUCTION: Anastomotic margin tissue perfusion is recognized as critical to successful colorectal anastomosis creation. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) is the most common modality used by surgeons as an adjunct to clinical assessment in confirming the adequacy of tissue perfusion. Tissue oxygenation as a surrogate for tissue perfusion has been described in a variety of surgical specialties but its use in colorectal surgery has been limited. Here, we report our experience using a handheld tissue-oxygen meter, IntraOx, for the evaluation of colorectal tissue bed oxygen saturation (StO2) and compared its utility with NIR-ICG in identifying the viability of colonic tissue before anastomosis in a range of colorectal procedures...

BACKGROUND: Cystic tumors in the presacral space represent a rare pathology. In case of symptoms, but particularly due to the danger of malignant degeneration, surgical removal is indicated. Due to the complex position in the pelvis with its proximity to important anatomic structures, the choice of the surgical approach is decisive. METHODS: To present an overview of the recent knowledge of presacral tumors, a PubMed-based literature review was performed. Subsequently, we present 5 cases where different surgical strategies were evaluated including a video of a laparoscopic removal...

BACKGROUND: Obesity is associated with an increased risk of ventral hernia development and recurrence rates after ventral hernia repair (VHR). The metabolic derangements caused by obesity can also lead to many postoperative complications. Therefore, it is a common practice to attempt weight loss before VHR. However, there is still no consensus on optimal preoperative management for obese patients with a ventral hernia. This study aims to perform a meta-analysis to evaluate the effect of preoperative weight optimization on VHR outcomes...

BACKGROUND: Gastroesophageal reflux disease (GERD) remains one of the most commonly encountered gastrointestinal disorders. Proton pump inhibitors still show an inadequate effect on about 10% to 40% of the patients. Laparoscopic antireflux surgery is the surgical alternative for managing GERD in patients who are not responding to proton pump inhibitors. AIM OF THE STUDY: This study objected at comparing laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication (LTF) concerning the short-term and long-term outcomes...

BACKGROUND: One-anastomosis gastric bypass (OAGB) has become an accepted metabolic/bariatric surgery procedure. This study aimed to describe our center's standardized OAGB operative technique and report early (≤30 d) safety outcomes in patients with severe obesity. METHODS: The medical records of patients who had undergone either primary (n=681, 88.0%) or revisional OAGB (n=93, 12.0%) were retrospectively evaluated. Patient demographics, operative time, length of hospital stay, readmissions, reoperations, and ≤30-day morbidity and mortality rates were analyzed...

BACKGROUND: Up to 70% of the cases of biliary strictures are cholangiocarcinoma. Cholangiocarcinoma has a late diagnosis and poor outcomes; therefore, effective biomarkers are needed for malignant lesions detection at earlier stages. AIM: The aim was to assess the diagnostic utility of bile pyruvate kinase M2 (PKM2) as a biomarker for the detection of malignant biliary strictures in patients with an indeterminate biliary stricture. MATERIALS AND METHODS: This is a prospective study to evaluate the diagnostic value of bile PKM2 for the diagnosis of malignant biliary strictures...

OBJECTIVES: Colonic angiodysplasia is a rare disease, it is nevertheless a common cause of lower gastrointestinal (GI) bleeding in older adults. The study summarized the colonoscopic and clinical features of colonic angiodysplasia to raise awareness among endoscopists regarding this disease. MATERIALS AND METHODS: We performed a retrospective study of enrolled patients diagnosed with colonic angiodysplasia between September 2013 and April 2022. Clinical and colonoscopic features of the patients with active bleeding were analyzed and compared with those of patients without bleeding...

BACKGROUND: Diastasis recti (DR) is defined as the separation of the rectus muscles as a result of the linea alba thinning and stretching. The purpose of this study was to evaluate the long-term outcomes of a new technique, robotic rectus abdominis medialization (rRAM), for DR repair with a concomitant ventral hernia. METHODS: Patients who underwent rRAM for repair of DR and a concomitant ventral hernia were identified between January 2015 and December 2020. The results are from a single surgeon at a single institution...

PURPOSE: The purpose of this study is to compare short-term and midterm outcomes between patients with acute pancreatitis (AP) treated with minimally invasive surgery (MIS) and patients treated with open necrosectomy (ON). MATERIALS AND METHODS: We compared data of all patients who had undergone MIS for AP with a similar group of patients with ON patients between January 2012 and June 2021 using a case-matched methodology based on AP severity and patient characteristics...

BACKGROUND: During the last year, there was a large COVID-19 vaccination campaign in Italy. Concurrently, metabolic bariatric surgery (MBS) restarted after a long period of discontinuity. No data are currently available on the best timing of COVID-19 vaccination for MBS candidates. The aim of this study was to report MBS outcomes in relation to the timing of COVID-19 vaccine administration. MATERIALS AND METHODS: A prospectively maintained database was utilized to locate patients undergoing MBS between January 1 and December 31, 2021...

BACKGROUND: Colorectal cancer primarily arises from colorectal polyps. Early screening and removal is beneficial, especially in asymptomatic populations. This research aimed to reveal the risk factors detected in medical check-ups for colorectal polyps in asymptomatic people. MATERIALS AND METHODS: Clinical data of 933 asymptomatic people who underwent colonoscopies from May 2014 to December 2021 was analyzed retrospectively. Data included sex, age, colonoscopy findings, polyp pathology, polyp number, and blood test results...

Valvuloplastic esophagogastrostomy by the double flap technique (VPEG-DFT) after proximal gastrectomy for early proximal gastric cancer or esophagogastric junctional cancer (EGJC) is a promising procedure to prevent reflux. However, the transhiatal procedure alone for alimentary reconstruction is sometimes too complex because of the short esophageal remnant. Therefore, additional transthoracic procedures are needed in some patients with EGJC. Although additional thoracoscopic surgery has been reported, no reports to date have described robotic transthoracic VPEG-DFT after excision of EGJC...

PURPOSE: Postoperative nausea and vomiting (PONV) is one of the most common adverse effects of anesthesia and surgery, resulting in patient discomfort and dissatisfaction. Latest research has demonstrated the efficacy of NK-1 receptor antagonists in PONV management and its use in chemotherapy nausea prophylaxis. The authors of this article would like to provide evidence to support the use fosaprepitant, as monotherapy, in postoperative care, replacing a polypharmacological standard of care regimen...

BACKGROUND: Ten to 15% of the common bile duct (CBD) stones require advanced endoscopic extraction techniques during endoscopic retrograde cholangiopancreatography. The study aimed to evaluate the efficacy and safety of fully covered self-expandable metal stents (FC-SEMS) for facilitating the extraction of difficult bile duct stones. METHODS: Patients who received FC-SEMS for the extraction of difficult CBD stones were retrospectively reviewed. Group 1 included patients with extrahepatic stones above a distal CBD stricture, Group 2 included patients with intrahepatic stones above a hilar stricture, and Group 3 included patients with complex stone(s) and no biliary stricture...

BACKGROUND: Our aim was to determine the efficacy and safety of intragastric balloon (IGB) application and the factors affecting its success by evaluating the results of patients who underwent IGB. MATERIALS AND METHODS: A total of 277 consecutive patients that underwent IGB between January 2019-September 2020 in our clinic were evaluated. Patients' demographic data, height and weight before the IGB procedure, weight at 6 and 12 months after the procedure, follow-up period, complication status, and whether they received dietician's assistance during the follow-up were recorded...

BACKGROUND: Thermal ablation is an accepted treatment modality for small and central liver tumors. In extensive colorectal liver metastatic disease (CRLM), hepatectomy can be combined with ablation, resulting in a parenchymal-sparing strategy. This may increase salvageability rates in case of recurrence. METHODS: All patients with advanced CRLM that underwent combined ablation and resection between April 2012 and April 2021, were retrospectively analyzed from a prospectively maintained database...

BACKGROUND: Laparoscopic distal pancreatectomy (L-DP) is the standard procedure for treating left-sided pancreatic tumors. Stapler closure of the pancreas is the preferred method for L-DP; however, postoperative pancreatic fistula (POPF) remains a challenging problem. The present study aimed to compare the surgical outcomes of staple closure using a reinforcing stapler (RS) and transection using an ultrasonic dissector followed by hand-sewn (HS) closure in a fish-mouth manner in pure L-DP and to determine independent perioperative risk factors for clinically relevant postoperative pancreatic fistula (CR-POPF)...
