Transanal minimally invasive surgery for benign and malignant rectal lesions: midterm outcomes from a tertiary center.

Background: Although transanal minimally invasive surgery (TAMIS) for rectal neoplasia has gained wide acceptance, the mid-term and long-term outcomes are not widely reported in the literature.

Objective: Describe the mid-term outcomes of patients who underwent TAMIS for benign and malignant rectal lesions in a single center.

Design: Retrospective cohort study.

Colonic medullary carcinoma: an exceedingly rare type of colorectal malignancy: a case report and review of the literature.

Background: Medullary carcinoma of the colon is a rare subtype of colorectal cancer that has a unique, and sometimes varied, clinical and histologic profile. It usually presents in adult patients older than 50 years. Here, we report a unique case of young male patient who initially presented with abdominal pain followed by a large bowel obstruction.

Spontaneously Ruptured Idiopathic Mesenteric Hematoma: A Case Report With Review of Literature.

Ruptured mesenteric hematoma is a rare entity that is not frequently reported in the literature. Spontaneous rupture of mesenteric hematoma has been vaguely described in a handful of cases. The majority of cases (unlike ours) had a reported etiology, like trauma, postoperative complications, connective tissue disease, and coagulopathy.

A Rare Case of COVID-19 Infection Leading to Colonic Stricture: Case Report and Review of Literature.

Coronavirus disease 2019 (COVID-19) predominantly targets the respiratory tract; despite gastrointestinal (GI) symptoms that may present in many patients, colonic strictures in coronavirus disease (COVID-19) patients are extremely rare and, to our knowledge, have never been reported. We, herein, present a case of a 59-year-old lady who developed intestinal obstruction due to colonic strictures shortly after recovering from complicated COVID-19 pneumonia. Ultimately, she underwent laparoscopic subtotal colectomy with ileorectal anastomosis.

Bilateral Primary Adrenal B-Cell Lymphoma Diagnosed by Workup for Primary Adrenal Deficiency.

Primary adrenal lymphoma (PAL) often occurs bilaterally and is a rare malignancy of old age. Workup for primary adrenal insufficiency often unmasks this underlying grave pathology. In this article, we present a case of a 73-yearold patient who presented with features of primary adrenal insufficiency and renal colic.

Meckel's Diverticulum Enterolith: A Rare Cause of Perforation and Small Bowel Obstruction Presenting as Acute Abdomen.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. MD enteroliths are an uncommon entity that could rarely present with complications. We, herein, present a case of a 56-year-old man who presented with severe abdominal pain.

Acute Appendicitis Presenting As Epigastric Pain Due to Incomplete Intestinal Malrotation.

Acute appendicitis is one of the most frequent causes of acute abdominal pain. Clinical signs, blood tests, and imaging are important to confirm the diagnosis. The classic presentation consists of periumbilical abdominal pain that migrates to the right lower quadrant, guarding, tenderness, and rebound tenderness in the region.

Platelet to Lymphocyte Ratio Associated with Prolonged Hospital Length of Stay Postpeptic Ulcer Perforation Repair: An Observational Descriptive Analysis.

Background: The predictive role of platelet to lymphocyte ratio (P/LR) in patients with perforated peptic ulcer (PPU) is not well-studied. We aimed to investigate the association between the P/LR ratio and the hospital length of stay (HLOS) for surgically treated PPU.

Method: This is a retrospective observational study for surgically treated adult cases of PPU at Hamad Medical Corporation during the period from January 2012 to August 2017.

Appendicitis Secondary to Trauma following a Camel Kick: Case Report and Review of Literature.

Introduction: Independently, trauma and appendicitis are two of the most common conditions in surgical practice. Rarely, both conditions may coexist, which raises the controversy whether it is merely a coincidence or trauma may lead to acute appendicitis. .

What you see might not be what you get: Discrepancies between intraoperative findings and preoperative diagnosis of ovarian tumors. Appendicular mucocele presenting as an adnexal mass - Case report and review of literature.

Introduction: Adnexal masses include those affecting the ovary or fallopian tubes. We report a unique case with discrepancy between the pre-operative diagnosis (adnexal mass) and the post-operative definitive findings (appendicular tumor invading ovary). We also employ a literature review to provide four scenarios of uncertainty that are encountered between appendiceal and adnexal masses.

Rare presentation of primary varicella zoster as fatal fulminant hepatitis in adult on low-dose,short-term steroid: Case report.

Background: Varicella zoster virus presents clinically as primary (chickenpox) or secondary (herpes zoster) infection. Cutaneous and extracutaneous dissemination may occur, usually in immunocompromised patients. VZV hepatitis that progresses to fulminant hepatic failure is very rare and fatal.

Assessment of PULP score in predicting 30-day perforated duodenal ulcer morbidity, and comparison of its performance with Boey and ASA, a retrospective study.

Background: : Scores commonly employed to risk stratify perforated peptic ulcer patients include ASA (American Society of Anesthesiologists), Boey and peptic ulcer perforation score (PULP). However, few studies assessed and compared the accuracy indices of these three scores in predicting post PPU repair 30-day morbidity. We assessed accuracy indices of PULP, and compared them to Boey and ASA in predicting post perforated duodenal (PDU) ulcer repair 30-day morbidity.
