Blood salvage and autotransfusion during orthotopic liver transplantation for hepatocellular carcinoma: A systematic review and meta-analysis.

Background: Hepatocellular carcinoma (HCC) is a significant cause of oncologic mortality worldwide. Liver transplantation represents a curative option for patients with significant liver dysfunction and absence of metastases. However, this therapeutic option is associated with significant blood loss and frequently requires various transfusions and intraoperative blood salvage for autotransfusion (IBS-AT) with or without a leukocyte reduction filter.

Analysis of deferral times in patients diagnosed with acute appendicitis.

Introduction: There are still controversies regarding the time of surgical management for acute appendicitis (AA). The main objective of this study was to recognize the surgical deferral time in patients with acute appendicitis and its relationship with the severity of presentation.

Materials And Methods: We performed a retrospective review of prospectively collected data of all patients with acute appendicitis undergoing appendectomy from August 2018 to August 2020 in an academic, public hospital.

Esophageal Duplication Cysts in 97 Adult Patients: A Systematic Review.

Background: Esophageal duplication cysts are a rare congenital cystic malformation from faulty intrauterine recanalization of the esophagus during the 4-8 weeks of development. They account for 20% of all gastrointestinal duplication cysts and commonly involve the distal esophagus. Presenting symptoms may be related to size and location.

A fecalith mimicking a bladder calculus secondary to an appendicovesical fistula: a case report.

An appendicovesical fistula is defined as an abnormal communication between the appendix and the urinary bladder, with only a few cases reported in the literature. It is very challenging to make an early diagnosis, due to the inability of conventional imaging modalities to detect this unique pathology. The symptoms are often mild, and there are not any specific signs or symptoms that might suggest this type of anomalous communication.

Use of the self-reported critical view of safety in laparoscopic cholecystectomy during residency.

Background: Even though the goal of safely performing cholecystectomy is already a priority in general surgical training programs, we aimed to study how many residents and attendings reached the critical view of safety (CVS) in laparoscopic cholecystectomy.

Materials And Methods: Retrospective review of prospectively collected data of all patients with biliary surgical conditions, which underwent laparoscopic cholecystectomy and their corresponding postoperative notes with self-reported CVS from May 2019 to May 2020 in an academic hospital. Comparisons of operative variables between postgraduate year and attendings were made.

Giant intramuscular thigh lipoma: A case report and review of literature.

Introduction: Lipomas are the most common soft tissue tumor. Giant lipomas are defined by measuring at least 10 cm in diameter in one dimension or by a minimum of 1000 g. They often are asymptomatic; however, they can cause compression syndromes due to nerve damage and difficulties in walking.

Pregnant patients with internal hernia after gastric bypass: a single-center experience.

Background: Bariatric surgery has been a popular way for many women to reach a healthy body mass index, and as a consequence, a decreased body mass, which causes a greater chance of fertility, with improved pregnancy and better maternal outcomes.

Objective: Describe a single-center experience of pregnancies complicated by internal hernias after gastric bypass.

Setting: Academic Medical Center.

Mirizzi syndrome from type I to Vb: a single center experience.

Objectives: The present study describes a cohort of patients diagnosed with Mirizzi syndrome from type I to Vb, over a period of four years. It aimed to identify diagnostic and management pitfalls of Mirizzi syndrome, as well as their concomitant cholecystobiliary or cholecystoenteric fistulas.

Material And Methods: We retrospectively reviewed all electronic medical records of patients who underwent surgery for Mirizzi syndrome at a single institution.

Transferring face-to-face sessions to virtual sessions in surgical education: a survey-based assessment of a single academic general surgery program.

Background: The purpose of this survey-based study was to evaluate the implementation of virtual learning in a single academic general surgery program, compared with the well-established face-to-face academic curriculum used before.

Methods: From April 2020 to the present, virtual sessions were created via Zoom Videos Communications, Inc. (San Jose, CA, USA).

Single-operator cholangioscopy and electrohydraulic lithotripsy for the treatment of Mirizzi syndrome.

Introduction: Mirizzi syndrome is an infrequent complication of long-standing cholelithiasis. Extrinsic compression of the common hepatic duct is usually caused by an impacted stone in Hartmann's pouch or cystic duct resulting in the development of cholecystobiliary fistula. This syndrome is classified based on the presence and severity of cholecystobiliary fistula.

Bowel obstruction as a serious complication of patients with femoral hernia.

Purpose: The implications of bowel obstruction occurring secondary to femoral hernia have not been discussed in the literature recently. Thus, we report our experience of treating patients with femoral hernias complicated by bowel obstruction versus patients with femoral hernias not complicated by bowel obstruction.

Methods: The subjects of this retrospective study were patients admitted to our hospital for the treatment of femoral hernias between 2016 and 2019.

Splenic Primary Solid Tumors : Does a Preoperative Histopathology Diagnosis Really Matter?

Background: The present study aims to present a case series of patients who underwent splenectomy for splenic primary solid tumors without preoperative histopathologic diagnosis.

Methods: From 2013 to 2019, 12 patients underwent splenectomy for solid primary splenic tumors at 3 different academic medical centers. All electronic medical records were retrospectively reviewed.

Ileal bezoar causing bowel obstruction mimicking an internal hernia in a patient with Roux-en-Y gastric bypass.

We presented a case of a 64-year-old female patient with a history of gastric bypass that presented with bowel obstruction due to a bezoar. She arrived at the emergency department, referring to severe abdominal pain, nausea, and vomiting. Abdominal X-ray reported gastric distention and hydro-air levels.

Acute Colonic Volvulus in a Mexican Population: A Case Series.

Purpose: Colonic volvulus constitutes a significant cause of large bowel obstruction in adults. Most studies of colonic volvulus come from high endemic zones and are limited by the small number of patients. In our region, there is a shortage of studies concerning this disorder, and treatment of colonic volvulus remains controversial.

Cholecystoenteric fistula with and without gallstone ileus: A case series.

Background: A cholecystoenteric fistula (CEF) is an uncommon complication of gallstone disease. The aim of this study was to present our experience of a series of patients with CEF, presenting with or without gallstone ileus, along with their surgical outcomes.

Methods: From 2015 to 2018, 3245 consecutive patients underwent cholecystectomy for gallbladder disease at our institution, of which 15 were diagnosed with a CEF.

Persistence of a vitelline artery on a Meckel's diverticulum as a cause of bowel infarction.

Meckel's diverticulum is a congenital anomaly, resulting from incomplete obliteration of the most proximal portion of the omphalomesenteric duct. It generally remains silent, but life-threatening complications may arise in 4-6% of the patients. We present a case of a 16-year-old male, who arrived at the emergency room with crampy abdominal pain, nausea, and vomiting, suggestive of acute appendicitis.

Laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography for choledocholithiasis after Roux-en-Y gastric bypass: A case report.

Background: Exclusion of the stomach after Roux-en-Y gastric bypass (RYGB) makes access to the biliary tree very challenging for the surgeon or the endoscopist. Different techniques have been described to overcome this downside, including laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography (ERCP), which is an outstanding method to access the remnant stomach in order to reach the duodenal papilla. The use of this technique is associated with a high success rate.

A giant splenic hamartoma associated with hematologic disorders: A case report.

Introduction: Splenic hamartoma is a primary benign tumor of the spleen, with approximately 150 cases documented in the literature to date, with only a few cases associated with symptoms and hematologic disorders.

Presentation Of Case: A 49-year-old female with no past medical history, presented to the emergency department complaining of a three-month history of intermittent abdominal pain and 12 kg of weight loss. Physical examination revealed abdominal distension and a big palpable and painless mass on the left side of her abdomen measuring 14 cm.
