Groove pancreatitis (GP) is an underrecognised subtype of chronic pancreatitis, focally affecting the area between the duodenum and pancreatic head. It most commonly affects males between 40 and 50 years of age with a history of alcohol misuse. Patients most commonly complain of abdominal pain and vomiting. Due to its focal nature, it is a potentially surgically treatable form of chronic pancreatitis. We report results of patients surgically treated for groove pancreatitis followed by a literature review of patient outcomes post resection.A retrospective chart review of patients with histopathologically confirmed GP post-surgical resection at the Princess Alexandra Hospital and Greenslopes Private Hospital in Brisbane, Australia was conducted between 2013 and 2020. Diagnosis was confirmed histologically when Brunner gland hyperplasia and chronic inflammation/fibrosis were found within the pancreaticoduodenal interface. Preoperative and postoperative symptoms were analysed along with complications. Additionally, a systematic review on outcomes of patients undergoing pancreaticoduodenectomy (PD) for GP was performed from three databases.Eight patients underwent surgery for GP. Elimination of preoperative symptoms was achieved in five of the eight patients. Major complications included one take back to theatre for pancreatic leak. Our literature review found complete resolution of pain and vomiting in 80% of GP patients after PD.Optimal management of GP begins with early recognition. Symptoms from GP are likely to respond well to surgical intervention. We advocate for aggressive surgical resection in a patient with a high index of suspicion for GP.

The induced membrane technique is a simple, effective, and reproducible treatment method for segmental bone defects. It is a 2-stage approach that requires eventual autologous bone graft to manage the deficit. The first stage requires debridement of all nonviable tissue while preserving a healthy soft tissue envelope. A polymethylmethacrylate is implanted between the osseous segments to maintain length. The osseous defect can be stabilized internally or externally. During the second stage, a vascularized induced membrane is formed and produces multiple growth factors. The induced membrane technique is a valuable option for limb salvage in cases of segmental bone defects.

Acute pancreatitis (AP) is one of the most common general acute surgical presentations. Current recommendations are that idiopathic acute pancreatitis (IAP) should account for no more than 20% of AP cases. Some studies suggest gallbladder microlithiasis is the aetiology in up to 75% of IAP patients. Endoscopic ultrasound (EUS) has been reported to be effective in the detection of microlithiasis and choledocholithiasis as well as pancreatic parenchymal, ductal and ampullary disorders. The aims of this study were to evaluate the usefulness of EUS in establishing aetiology in IAP patients and to assess if there is a role for EUS in the selection criteria for laparoscopic cholecystectomy to treat a potential biliary cause in IAP patients. A systematic review following PRISMA guideline was performed to gather data on patients with IAP undergoing EUS for further investigation. Three databases (MEDLINE, PubMed, and EMBASE) were searched to 28 July 2018. Our systematic review included 28 studies, comprising 1850 patients with an initial diagnosis of IAP prior to having EUS. Diagnosis of a potential aetiology or associated pancreatic pathology was established in 1095 (62%, p

The sural flap procedure is a versatile technique that can be used to cover many types of defects about the lower extremity. The management of soft tissue defects of the lower extremity with underlying osteomyelitis is difficult. The goal for any of these patients is to create a biomechanically stable foot for weight-bearing purposes with no continued infection. Data were gathered using multiple databases from the years 2000 to 2016. Data were compiled looking at the number of subjects, age, comorbidities, number of complications, number of failures, and average flap size of complications/failures. A total of 110 patients were gathered using 5 separate articles. Twenty-two of the 110 patients had short-term complications. Flap failure was seen in 9/110 patients. A significant difference was noticed in flap size between flap failure and complication groups and nonfailure groups. The average flap size of patients who had some form of complication or failure was 51.87 cm2 in size. The average graft size for patients without complications during their recovery was 36.54 cm2. Within our study, the failure rate of 8.9% and complication rate of 13.7% are consistent with previous reports on sural perforator flaps. Last, with regard to the effect of flap size, there were significant differences between patients with a successful outcome and those who experienced complications or failures.

A 49-year-old man presented with a 2-week history of gradual onset progressively worsening left upper quadrant pain. Ten months prior, he had a laparoscopic roux-en-Y gastric bypass (LRYGBP) for severe gastro-oesophageal reflux disease and obesity. On examination, his abdomen was not distended and was soft to palpation. The haemoglobin, white cell count, liver function test, lipase and lactate were normal. An abdominal CT scan demonstrated swirl sign. Given the suspicion of internal herniation, laparoscopy was performed demonstrating only partial closure of the jejuno-jejunal mesodefect resulting in herniation of the small bowel alimentary limb. Internal herniation should be considered as a differential diagnosis in all patients with previous LRYGBP and unexplained abdominal pain, nausea or vomiting. If closure of a mesodefect is to be attempted, a running, braided, non-absorbable suture should be used as a purse-string to avoid small defects with subsequent weight and mesenteric fat loss following bariatric surgery.

A 35-year-old man presented to a regional hospital after being kicked by a horse in the right upper quadrant. He was transferred to our hepatobiliary unit with bile peritonitis 8 days post trauma. Laparoscopic cholecystectomy and intraoperative cholangiography were performed, demonstrating distal common bile duct (CBD) obstruction with contrast extravasation from the distal duct. The CBD was drained with a T-tube via laparotomy. On postoperative day 14, T-tube cholangiography demonstrated no extravasation of contrast from the distal CBD and minor stricturing with eventual duodenal drainage. The T-tube was clamped and 5 weeks later, the patient represented with peri-T-tube bile leakage and right upper quadrant pain. A T-tube cholangiogram confirmed a complex distal CBD stricture. Two attempts at ERCP with intent of stenting the stricture were unsuccessful. The patient underwent an end to side Roux-en-Y choledochojejunostomy and was discharged home 4 days postoperatively on simple analgesia.

Background Extrahepatic bile duct injuries (EHBDIs) are a rare consequence of blunt abdominal trauma. The purpose of this study was to establish mechanisms of injury, clinical indicators of EHBDI following blunt trauma (both with investigative modalities and intraoperatively), method and timing of injury detection, and definitive treatment options. Methods A systematic review was performed to gather data on patients with an EHBDI secondary to blunt trauma. Three databases (MEDLINE, PubMed, and EMBASE) were searched to July 19, 2018. Results Our systematic review included 51 studies, compromising a study population of 66 patients with EHBDIs sustained from blunt trauma. The three most common injuries included complete transection of the suprapancreatic common bile duct (29%, n = 19), complete transection of the intrapancreatic common bile duct (23%, n = 15) and partial laceration of the left hepatic duct (20%, n = 13). Of the hemodynamically stable group managed nonoperatively (n = 23), mean timing postinjury to diagnosis of EHBDI was 11 days. An EHBDI was recognized at initial laparotomy in 87% (n = 13) of hemodynamically stable patients. An EHBDI was recognized at initial laparotomy in 57% (n = 8) of hemodynamically unstable patients. Conclusion The EHBDIs are a rare yet serious consequence of blunt trauma. To establish a timely diagnosis and limit complications of missed injuries, a heightened awareness is required by the attending surgeon with particular attention to subtle yet important clinical indicators. These vary depending on the hemodynamic stability of the patient and decision to manage injuries conservatively or surgically on presentation. Level of evidence Systematic review, level III.

Background A left-sided gallbladder (LSGB) is a rare anatomical anomaly that is often not discovered until surgery. Two cases of LSGB managed with laparoscopic cholecystectomy (LC) stimulated this systematic review. The aims of this study were in LSGB to define the rate of pre-operative detection, variations in biliary anatomy, laparoscopic techniques employed and outcomes of surgery for symptomatic gallstones. Methods A systematic review was performed using Preferred Reporting Items for Systematic reviews and Meta-Analyses principles. Results Fifty-three studies with 112 patients of which 90 (80.4%) had symptomatic gallstones. Pre-operative imaging was performed in 108 patients (96.4%) with an LSGB reported on imaging in 32 (29.6%) patients. The remainder of LSGB were discovered at surgery. Ultrasound detected an LSGB in three (2.7%) patients. Five variants of cystic union with the common hepatic duct (CHD) were identified. The most common (67.8%) was union on the right side of the CHD after a hairpin bend anterior to the CHD. A cholecystectomy for gallstone disease was performed in 90 patients, 23.3% open and 76.7% LC. Common variations in LC technique were different port site placement and techniques related to the falciform ligament to improve exposure. Common bile duct injury occurred in four (4.4%) patients. Conclusion LSGB is a rare anatomical variation that in patients with symptomatic gallstones is usually discovered at surgery. Cholecystectomy is associated with a higher incidence of common bile duct injury.
