Purpose: To evaluate the added value of the diffusion tensor imaging (DTI) parameters to abbreviated breast MRI protocol in differentiating recurrent breast cancer from post-operative changes in cases of breast conservative surgery (BCS).

Methods: This prospective study was approved by our institutional review board. Written informed consent was obtained in all patients.

Article Synopsis
  • Diabetic mastopathy is a rare benign breast condition characterized by fibrous lumps, typically seen in patients with type 1 or 2 diabetes, and is often linked to hyperglycemia.
  • The diagnosis can be confusing due to similar clinical and radiographic features, making pathological confirmation crucial to rule out cancer.
  • In a reported case, diabetic fibrous mastopathy was diagnosed despite no prior history of diabetes, highlighting the need to consider this condition in the differential diagnosis of breast lumps, even in patients without known diabetes.

Article Synopsis
  • The study evaluates the outcomes of sphincter-sparing techniques combined with total mesorectal excision (TME) for treating anorectal adenocarcinoma, involving 93 patients over five years.
  • The methods included various surgical approaches such as intersphincteric resection and assessed anal function one year post-surgery using the Per Anal Examination Scoring System (PASS).
  • Results showed that while about 10.6% of patients experienced fecal incontinence, most retained normal anal tone, indicating that sphincter preservation is effective in avoiding permanent stomas and maintaining reasonable function.

Video endoscopic inguinal lymphadenectomy (VEIL) is a minimally invasive technique that gives superior surgical outcomes than open inguinal lymphadenectomy (IL) for treating lymph node metastasis in penile, vulvar, and skin cancers. This study compared surgical outcomes obtained with two different approaches of VEIL, standard VEIL and lateral VEIL (L-VEIL), in cancer patients. Sixty-two patients who underwent standard VEIL ( = 15) or L-VEIL ( = 47) for treatment of lymph node metastasis were evaluated retrospectively from three centers in Brazil, Egypt, and India.

Performing pedicled TRAM in obese women carries risk of flap loss or native breast envelop necrosis. Our technique depends on performing total flap delay at the same setting with mastectomy with flap suture in situ to be followed 1 week later by flap transfer. This study included 24 operable women who were candidates for skin sparing or modified radical mastectomy.

Background: Rectal cancer is now an increasing problem in both developed and developing countries. In the last 7 years, minimally invasive surgery for this disease has entered a new era of transanal resection with/without laparoscopic assistance.

Materials And Methods: We present here a prospective study done in Egypt (probably the earliest experience) and Spain on the feasibility of hybrid NOTES in rectal cancer.

Background: Mucinous adenocarcinoma (MA) is a unique subtype of colorectal carcinoma. Although some investigators considered MA a predictor for poor prognosis, predictors for poor clinical outcome of MA were not elucidated. The present study aimed to investigate the predictors for local recurrence and distant metastasis of MA.

The surgical management of stump carcinoma includes the gold standard pelvic exenteration and more conservative approaches. This study aimed to investigate the outcome among a cohort of vaginal and cervical stump carcinomas that were treated with an intent of organ preservation. This is a prospective study of 60 patients with a biopsy confirmed stump carcinomas at a tertiary care oncology center in Egypt.

Purpose Of The Study: The study compares prospectively the hospital stay and postoperative complications of anterior (ALS) versus lateral (LLS) approach for laparoscopic splenectomy.

Materials And Methods: Between September 2011 and April 2015, 94 patients with splenomegaly were referred to the surgical unit in the Oncology Center of Mansoura University, Egypt. Only 80 patients with splenomegaly <30 cm underwent an open-label randomized allocation into 2 equal parallel groups.

Background: This study was designed to investigate the impact of liver cirrhosis due to chronic hepatitis C virus (HCV) infection on the disease-free and overall survival of ovarian cancer patients undergoing a standard primary operation followed by standard chemotherapy. Attainment of the operative goals, intra- and postoperative events, possible complications under chemotherapy necessitating the termination of treatment, and the impact of ovarian cancer treatment on liver function were assessed.

Methods: This was a prospective observational study that included only patients with primary epithelial ovarian cancer.

Introduction: Thyroid cancer is the most common endocrine malignancy; the most common type of thyroid cancer is papillary thyroid cancer which accounts for approximately 90% of all thyroid cancers. Previously defined prognostic factors of papillary thyroid cancer include age, gender, tumor size, extrathyroidal extension, and distant metastasis. Cervical lymph node metastases are very common in patients with papillary thyroid cancer.

Background: The aim of this study is to define an algorithm for the choice of reconstructive method for defects after laryngo-pharyngo-esophagectomy for hypopharyngeal carcinoma.

Methods: One hundred and forty two cases of hypopharyngeal carcinoma were included and operated on by either partial pharyngectomy, total pharyngectomy or esophagectomy. The reconstructive method was tailored according to the resected segment.

Background: Surgical management of breast cancer in large-breasted women presents a real challenge. This study aims to evaluate the outcome of therapeutic reduction mammoplasty in large-breasted women with breast cancer using superior and superomedial pedicles, situated at any breast quadrant except for the central and upper medial quadrants.

Methods: Fifty women with breast cancer and large breasts underwent simultaneous bilateral reduction mammoplasty.

Introduction: Psychiatric morbidities, especially cases of anxiety and depression, are prevalent among breast cancer patients and their partners.

Patients And Methods: Fifty-four early diagnosed breast cancer patients and their partners were compared with 50 healthy couples to assess psychiatric morbidity and the impact of various factors upon patients' surgical choice.

Results: It was found that 18.

Background: Cosmesis, better function, and stomal stricture avoidance are important issues in constructing continent urinary abdominal stomas for bladder cancer patients when orthotopic urinary diversion is not feasible. This study aims to evaluate the outcome of continent catheterizable umbilical low-pressure intestinal pouch incorporating a new split ileal end anti-reflux technique.

Methods: Twenty-three patients underwent a continent umbilical low-pressure intestinal pouch incorporating a new seromuscular antireflux technique (split ileal end) after radical cystectomy when orthotopic reconstruction was not feasible.
