Urethral Injury in Rectal Cancer Surgery: A Comprehensive Study Using Cadaveric Dissection, Imaging Analyses, and Clinical Series.

Male urethral injury during rectal cancer surgery is rare but significant. Scant information is available about the distances between the rectourethral space and neighboring structures. The aim of this study is to describe the anatomical relations of the male urethra.

Impact on defecatory, urinary and sexual function after high-tie sigmoidectomy: a post-hoc analysis of a multicenter randomized controlled trial comparing extended versus standard complete mesocolon excision.

Objective: To assess the effect of high inferior mesenteric artery tie on defecatory, urinary, and sexual function after surgery for sigmoid colon cancer. Performing a sigmoidectomy poses a notable risk of causing injury to the preaortic sympathetic nerves during the high ligation of the inferior mesenteric artery, as well as to the superior hypogastric plexus during dissection at the level of the sacral promontory. Postoperative defecatory and genitourinary dysfunction after sigmoid colon resection are often underestimated and underreported.

Is Metformin Associated With Improved Response to Neoadjuvant Chemoradiotherapy in Locally Advanced Rectal Cancer?

Background: Efforts to determine whether metformin can increase the effectiveness of neoadjuvant chemoradiotherapy in rectal cancer have increased in recent years. However, retrospective studies have yielded inconclusive results.

Objectives: The aim of this study was to compare oncological outcomes and survival after neoadjuvant chemoradiotherapy in patients with rectal cancer taking metformin versus in those not taking metformin.

Extended Versus Standard Complete Mesocolon Excision in Sigmoid Colon Cancer: A Multicenter Randomized Controlled Trial.

Objective: The aim of this study was to evaluate whether extended complete mesocolic excision (e-CME) for sigmoid colon cancer improves oncological outcomes without compromising morbidity or functional results.

Background: In surgery for cancer of the sigmoid colon and upper rectum, s-CME removes the lymphofatty tissue surrounding the inferior mesenteric artery (IMA), but not the lymphofatty tissue surrounding the portion of the inferior mesenteric vein that does not run parallel to the IMA. Evidence about the safety and efficacy of extending CME to include this tissue is lacking.

[Impact of SARS-COV-2 pandemic on elective and emergency surgery in a university hospital].

Introduction: SARS-CoV-2 pandemic has caused an important impact in our country and elective surgery has been postponed in most cases. There's not known information about the decreasing and impact on surgery. Mortality of surgical patients with SARS-CoV-2 infection is estimated to be around 20%.

Comparison of Outcomes between Obese and Nonobese Patients in Laparoscopic Adrenalectomy: A Cohort Study.

Introduction: Obesity is usually considered a risk factor for surgical complications. Laparoscopic adrenalectomy has replaced open adrenalectomy as the standard operation for adrenal tumors.

Objective: To compare the safety of laparoscopic adrenalectomy to treat adrenal tumors in obese versus nonobese patients.

Pure Laparoscopic Anatomic Resection of the Segment 8 Dorsal Area Using the Dorsal Approach of the Right Hepatic Vein.

Background: Anatomical resection of segment 8 (s8) is a challenging procedure. S8 can be subdivided into two areas: ventral (s8v) and dorsal (s8d). In the last years, different approaches for performing laparoscopic resection of s8 or any of its subsegments have been described, i.

Risk factors for suboptimal laparoscopic surgery in rectal cancer patients.

Purpose: Laparoscopic surgery for rectal cancer is technically complex. This study aimed to identify risk factors for suboptimal laparoscopic surgery (involved margins, incomplete mesorectal excision, and/or conversion to open surgery) in patients with rectal cancer.

Methods: We included patients undergoing laparoscopic anterior resection for rectal cancer between June 2009 and June 2018.

Randomized clinical trial comparing side to end vs end to end techniques for colorectal anastomosis.

Background: Low anterior resection syndrome affects 60%-90% of patients with anastomoses after colorectal resection. Consensus regarding the best anastomosis is lacking.

Objective: To compare outcomes after end-to-end versus side-to-end anastomoses.

Factors associated with prolonged hospital stay after laparoscopic adrenalectomy.

Laparoscopy is the standard technique for resecting adrenal tumors, but short-term outcomes such as length of stay (LOS) vary widely between centers. We aimed to identify factors associated with LOS after lateral transperitoneal laparoscopic adrenalectomy (LTLA). We analyzed consecutive patients undergoing unilateral LTLA between April 2003 and April 2020.

Three-dimensional (3D) system versus two-dimensional (2D) system for laparoscopic resection of adrenal tumors: a case-control study.

Purpose: Laparoscopy is the standard technique for resecting adrenal tumors worldwide. The main drawbacks of conventional 2D laparoscopy are limited depth perception and tactile feedback. Currently available high-quality 3D laparoscopy systems might improve surgical outcomes for adrenalectomy.

Impact of SARS-COV-2 pandemic on elective and emergency surgery in a university hospital.

Introduction: SARS-CoV-2 pandemic has caused an important impact in our country and elective surgery has been postponed in most cases. There's not known information about the decreasing and impact on surgery. Mortality of surgical patients with SARS-CoV-2 infection is estimated to be around 20%.

Delaying surgery by more than 10 weeks after long-course neoadjuvant radiotherapy in locally advanced rectal cancer patients improves pathologic complete response.

We currently do not know the optimal time interval between the end of chemoradiotherapy and surgery. Longer intervals have been associated with a higher pathological response rate, worse pathological outcomes and more morbidity. The aim of this study was to evaluate the effect and safety of the current trend of increasing time interval between the end of chemoradiotherapy and surgery (< 10 weeks vs.

Transanal surgery: A tool in the colorectal anastomotic leakage.

The treatment of anastomotic leakage after oncological surgery for rectal cancer is a surgical challenge. The goal of this study is to show how transanal surgery combined with the abdominal approach is a very useful tool to decide on individualized treatment depending on the degree of dehiscence and to assist us in its local management. We present three cases of patients with colorectal anastomotic dehiscence.

[Is body mass index a prognostic factor of survival in colonic cancer? A multivariate analysis].

Introduction: The long-term survival of patients operated on for colonic cancer depends on many factors. Obesity decreases the life expectancy of the general population who suffer from it, but it is not clear whether obesity, measured by the Body Mass Index (BMI), is a prognostic factor of survival for patients operated on for colonic cancer.

Material And Methods: The patients included in this study had TNM stage I, II y III, and were subjected to elective surgery for cancer of the colon in the Girona University Hospital between 1990 and 2001.

[The impact of obesity on the histopathological characteristics of colorectal tumours. An observational study].

Background: To asses the influence of body mass index on the tumour characteristics of patients subjected to colorectal cancer surgery.

Materials And Methods: Retrospective observational study. Patients subjected to curative elective colorectal cancer surgery at Hospital Josep Trueta de Girona (Spain), from 1990 to 2001.

Gastric necrosis: a possible complication of the use of the intragastric balloon in a patient previously submitted to nissen fundoplication.

The temporary use of the bioenterics intragastric balloon in morbid obesity is increasing worldwide. Generally, this is an effective procedure that helps bring about satisfactory weight loss and improvement in comorbidities after 6 months. However, in some cases, it causes complications such as acute abdomen due to gastric perforation and even death.
