The management of hemodynamically stable patients with anterior abdominal stab wounds (AASW) is debated. Mini-invasive techniques using laparoscopy and non-operative management (NOM) have reduced the rate of nontherapeutic laparotomies after AASW leading to unnecessary morbidity. The aim of this study was to determine with a systematic diagnostic laparoscopy of peritoneal penetration (PP), patients who do not require abdominal exploration in the management of stable patient with an AASW.

All patients with AASW were retrospectively recorded from 2006 to 2018. Criteria of inclusion were AASW patients who underwent a systematic diagnostic laparoscopy. Criteria of exclusion were patients with an evisceration, impaling, clinical peritonitis, and hemodynamic instability. If no PP was detected, laparoscopy was terminated. If defects of peritoneum were found, a laparotomy was performed looking for diagnosis and treatment of intra-abdominal injuries.

On 131 AASW patients, 35 underwent immediate emergency laparot, with a low duration of hospitalization, a possible ambulatory care and had an excellent ability to screen the patients who did not need a abdominal exploration. This management can avoid many unnecessary laparotomies with an acceptable rate of negative laparotomy, without any delayed diagnosis of intra-abdominal injuries and with a low morbidity rate.
The use of biologic mesh in paraesophageal hernia repair (PEHR) has been associated with decreased short-term recurrence but no statistically significant difference in long-term recurrence. Because of this, we transitioned from routine to selective use of mesh for PEHR. The aim of this study was to examine our indications for selective mesh use and to evaluate patient outcomes in this population.

We queried a prospectively maintained database for patients who underwent laparoscopic PEHR with biologic mesh from October 2015 to October 2018, then performed a retrospective chart review. The decision to use mesh was made intraoperatively by the surgeon. Dasatinib inhibitor Recurrence was defined as the presence of > 2cm intrathoracic stomach on postoperative upper gastrointestinal (UGI) series.

Mesh was used in 61/169 (36%) of first-time PEHRs, and in 47/82 (57%) of redo PEHRs. Among first-time PEHRs, the indications for mesh included hiatal tension (85%), poor crural tissue quality (11%), or both (5%). Radiographic recurreoor tissue quality, or prior recurrence. Despite the high risk for radiologic recurrence, there was only 1 reoperation for recurrence in the entire cohort.
Complications following laparoscopic cholecystectomy (LC) and common bile duct exploration (CBDE) for the management of gallstones or choledocholithiasis impact negatively on patients' quality of life and may lead to reinterventions. This study aims to evaluate the causes and types of reintervention following index admission LC with or without CBDE.

A prospectively maintained database of LC and CBDE performed by a single surgeon was analysed. Preoperative factors, difficulty grading and perioperative complications requiring reintervention and readmissions were examined.

Reinterventions were required in 112 of 5740 patients (2.0%), 89 (1.6%) being subsequent to complications. The reintervention cohort had a median age of 64years, were more likely to be females (p < 0.0023) and to be emergency admissions (67.9%, p < 0.00001) with obstructive jaundice (35.7%, p < 0.00001). 46.4% of the reintervention cohort had a LC operative difficulty grade IV or V and 65.2% underwent a CBDE. Open conversion wasmergencies and bile duct stones. Surgical or endoscopic reinterventions following LC alone occurred in only 0.8%. The most common form of reintervention was ERCP for retained CBD stones. This important outcome parameter of laparoscopic biliary surgery can be optimised through early diagnosis and timely reintervention for complications.
Per-oral cholangioscopy (POC) has evolved over the past decade from fiberoptic to digital and video imaging systems. Nowadays, only direct per-oral cholangioscopy (DPOC) and digital single-operator cholangioscopy (DS) are performed in daily practice. With better image resolution, POC is increasingly used as diagnostic tools in patients with suspected malignant biliary stricture (MBS). We aimed to evaluate the diagnostic yield of digital/video cholangioscopes for the diagnosis of MBS.

A systematic search was performed in MEDLINE, Embase, and ISI Web of Knowledge databases until April 2020, to identify randomized controlled trials and prospective studies using digital or video POC. The meta-analysis of diagnostic accuracy study was performed to calculate summary estimates of the primary outcomes, including pooled sensitivity, and specificity of POC to diagnose MBS using bivariate random-effects models. Tissue histopathology was used as the reference standard for MBS diagnosis. For benign stricture, negativeps as a trade-off.
Digital/video POC has very high diagnostic performance to diagnose MBS. While image diagnosis provides higher sensitivity than biopsy, its specificity drops as a trade-off.
While minimally invasive liver surgery has been increasingly adopted at least for minor resections, experience with robotic liver surgery is still limited to a few highly specialized centers. Due to the fear of abdominal adhesions, a history of prior surgeries is still used as an argument for open approaches.

Clinical data of all consecutive robotic resections at our center, using the da Vinci Xi surgical system, between April, 2018 and December, 2020, were collected and analyzed as part of a prospective, post-marketing observational study (DRKS00017229). Prior abdominal surgeries were specified according to the surgical approach and localization. Baseline and perioperative outcome criteria were compared between patients with prior surgeries (PS) and patients with no prior surgeries (NPS) in univariate and multivariate analyses.

Out of the 126 patients undergoing robotic liver resections, 59% had a history of abdominal surgeries, which were most often colorectal resections (28%) followed by liver resections (20%).
