Two stage hepatectomy (TSH) versus ALPPS for initially unresectable colorectal liver metastases: A systematic review and meta-analysis.

Background: Although numerous comparisons between conventional Two Stage Hepatectomy (TSH) and Associating Liver Partition and Portal Vein Ligation for staged hepatectomy (ALPPS) have been reported, the heterogeneity of malignancies previously compared represents an important source of selection bias. This systematic review and meta-analysis aimed to compare perioperative and oncological outcomes between TSH and ALPPS to treat patients with initially unresectable colorectal liver metastases (CRLM).

Methods: Main electronic databases were searched using medical subject headings for CRLM surgically treated with TSH or ALPPS.

From conventional two-stage hepatectomy to ALPPS: Fifteen years of experience in a hepatobiliary surgery unit.

Background: Hepatectomy in patients with large tumor load may result in postoperative liver failure and associated complications due to excessive liver parenchyma removal. Conventional two-stage hepatectomy (TSH) and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique are possible solutions to this problem. Colorectal liver metastases (CRLM) is the most frequent indication, and there is a need to assess outcomes for both techniques to improve surgical and long-term oncological outcomes in these patients.

Evaluation of patient safety and satisfaction in a program of ambulatory laparoscopic cholecystectomy program with expanded criteria.

Introduction: The good results obtained with the implementation of ambulatory laparoscopic cholecystectomy programs have led to the expansion of the initial inclusion criteria. The main objective was to evaluate the results and the degree of satisfaction of the patients included in a program of laparoscopic cholecystectomy without admission, with expanded criteria.

Methods: Observational study of a cohort of 260 patients undergoing ambulatory laparoscopic cholecystectomy between April 2013 and March 2016 in a third level hospital.

Update on the management of non-obstetric acute abdomen in pregnant patients.

Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup.

Risk factors for anastomotic leak and postoperative morbidity and mortality after elective right colectomy for cancer: results from a prospective, multicentric study of 1102 patients.

Background: Studies focused on postoperative outcome after oncologic right colectomy are lacking. The main objective was to determine pre-/intraoperative risk factors for anastomotic leak after elective right colon resection for cancer. Secondary objectives were to determine risk factors for postoperative morbidity and mortality.

Twenty-five years of ambulatory laparoscopic cholecystectomy.

It is accepted by the surgical community that laparoscopic cholecystectomy (LC) is the technique of choice in the treatment of symptomatic cholelithiasis. However, more controversial is the standardization of system implementation in Ambulatory Surgery because of its different different connotations. This article aims to update the factors that influence the performance of LC in day surgery, analyzing the 25 years since its implementation, focusing on the quality and acceptance by the patient.

Risk Factors for Anastomotic Leak After Colon Resection for Cancer: Multivariate Analysis and Nomogram From a Multicentric, Prospective, National Study With 3193 Patients.

Objective: To determine pre-/intraoperative risk factors for anastomotic leak after colon resection for cancer and to create a practical instrument for predicting anastomotic leak risk.

Background: Anastomotic leak is still the most dreaded complication in colorectal surgery. Many risk factors have been identified to date, but multicentric prospective studies on anastomotic leak after colon resection are lacking.

Management of cryptoglandular supralevator abscesses in the magnetic resonance imaging era: a case series.

Aim: The aim of this study is to describe the diagnostic performance of magnetic resonance imaging in the management of supralevator abscess, regarding its origin, location, drainage route, subsequent treatment of the fistula, and long-term results.

Methods: A retrospective case series including thirteen consecutive patients with cryptoglandular supralevator abscess treated between 2001 and 2011 at a colorectal unit of a tertiary referral center. A magnetic resonance imaging was performed in all patients before surgical drainage, and its usefulness in assessing supralevator abscess origin was analyzed.

Evaluation of mesorectal fascia in mid and low anterior rectal cancer using endorectal ultrasound is feasible and reliable: a comparison with MRI findings.

Background: Accuracy of MRI in assessing mesorectal fascia and predicting circumferential resection margin decreases in low anterior rectal tumors.

Objective: The purpose of this work was to evaluate the accuracy of endorectal ultrasound in predicting the pathologic circumferential resection margin in low rectal anterior tumors and to compare it with MRI findings.

Design: This was a prospective series comparing the preoperative circumferential resection margin assessed by endorectal ultrasound and MRI with pathologic examination.

Modified Wong's classification improves the accuracy of rectal cancer staging by endorectal ultrasound and MRI.

Background: Douglas Wong proposed a new classification of tumor penetration in the rectal wall (T stage) in an attempt to incorporate the prognostic heterogeneity of T3 rectal cancers into the preoperative staging.

Objective: This study aimed to evaluate if the accuracy of endorectal ultrasound and MRI in predicting rectal cancer T staging improves when using a modified Wong's classification.

Design: This prospective series compares local standard TN staging and a modified Wong's classification.

Glucagonoma syndrome: a case report.

Introduction: Glucagonoma syndrome is a rare paraneoplastic phenomenon, with an estimated incidence of one in 20 million, characterized by necrolytic migratory erythema, hyperglucagonemia, diabetes mellitus, anemia, weight loss, glossitis, cheilitis, steatorrhea, diarrhea, venous thrombosis and neuropsychiatric disturbances in the setting of a glucagon-producing alpha-cell tumor of the pancreas. Necrolytic migratory erythema is the presenting manifestation in the majority of cases, so its early suspicion and correct diagnosis is a key factor in the management of the patient.

Case Presentation: We present the case of a 70-year-old Caucasian woman with glucagonoma syndrome due to an alpha-cell tumor located in the tail of the pancreas, successfully treated with surgical resection.

Emergency surgery in chronic intestinal pseudo-obstruction due to mitochondrial neurogastrointestinal encephalomyopathy: case reports.

Chronic intestinal pseudo-obstruction (CIPO) is a syndrome characterized by recurrent clinical episodes of intestinal obstruction in the absence of any mechanical cause occluding the gut. There are multiple causes related to this rare syndrome. Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is one of the causes related to primary CIPO.
