Sarcopenia As a Determinant Prognostic Factor After Surgery Among Patients with Colorectal Cancer.

INTRODUCTION: Surgery for colorectal cancer (CRC) is not risk-free; therefore, preoperative evaluation must be done to predict and prevent surgical complications. Sarcopenia, a loss of muscle mass and function, was shown to be associated with surgical complications. Our study evaluates the effects of sarcopenia on short-term patient outcomes after CRC resection. MATERIALS AND METHODS: Our retrospective study included patients with histologically proven CRC between 2018 and 2020 who underwent surgical resection. Skeletal muscle mass (cm2) was evaluated on a preoperative CT scan at the level of L3 vertebrae then standardized using stature (m2) to obtain the skeletal mass index (SMI) (cm2/m2). Patients received proper adjuvant care if needed and were followed up 90 days post surgery. Descriptive statistics were presented in percentage for categorical variables and in mean for continuous variables. Multivariate was made by linear regression. RESULTS: 113 patients were included, and 15% were sarcopenic. A statistically non-significant association was found between sarcopenia and severe complications (grade III-IV) (23.53% in sarcopenic vs. 9.38% non-sarcopenic, p=0.02, multivariate p=0.675). Sarcopenia was not associated with anastomotic leakage, infectious complications, or ileus or intra-abdominal bleeding (p>0.05). In literature, some studies showed an association between sarcopenia and postoperative complications while others showed no relationship between the two. Most studies used SMI. CONCLUSION: A non-statistically significant association was found between sarcopenia and postoperative complications in CRC patients. Sarcopenia does not predict postoperative severe complications, anastomotic leakage, infectious complications, or ileus or intra-abdominal bleeding. Emergent surgeries and age >60 years were associated with more postoperative complications.

Incidental diagnosis of silent extrahepatic portosystemic shunt.

Extrahepatic portosystemic shunts are a very rare disease. Early diagnosis and appropriate treatment are needed to prevent serious complications. In asymptomatic patients, conservative treatment is an option.

Deadly Aspiration Pneumonia Secondary to Superior Mesenteric Artery Syndrome.

Superior mesenteric artery syndrome (SMAS) is a rare and unusual disease, suspected clinically and confirmed radiologically. It represents a duodenal obstruction secondary to the impingement of the third portion of the duodenum between the abdominal aorta (AA) and the superior mesenteric artery (SMA) due to decreased intraabdominal fat. High morbidity and mortality rates are linked to missed or late diagnosis that can lead to complications, such as gastric perforation and gastric hemorrhage. We present the case of a 33-year-old man who was not previously known to have a SMAS, who presented to the emergency department with signs of septic shock, complaining of fever and respiratory symptoms for several days. Investigations showed aspiration pneumonia secondary to an upper gastrointestinal obstruction with signs of SMAS on a computed tomography (CT) scanner. Acute and rapid deterioration led to cardiac arrest and death. Through this article, we highlight the importance of early and correct diagnosis of SMAS which can sometimes be challenging, since no number is strictly diagnostic and radiological images must be interpreted in light of the clinical history and physical examination.

Acute Appendicitis Caused by Metastasis from Other Organs: A Systematic Review.

BACKGROUND: Acute appendicitis resulting from inflammation of the mucosa is the most common cause of emergency surgical causes. However, acute appendicitis caused by metastasis from other organs is very rare. Patients having this entity were only described in the literature as case reports. This study aims to analyze data from published articles about this condition. METHODS: We performed a systematic review using the PRISMA protocol. PubMed/MEDLINE, Embase and the Google Scholar Library were searched up to the end of December 2022. RESULTS: A total of 34 patients were included, of which 22 were male. The mean age was 58.94. Primary site of tumors were mainly lungs (32.35%), breast (20.59%), and stomach (17.65%). All patients underwent surgical treatment except one patient who was given medical treatment. In 10 patients (29.41%), acute appendicitis was the initial manifestation to diagnose the primary malignancy and in 21 patients (61.77%), there were other sites of secondary lesions. Post operative mortality was reported in 1 patient (2.93%). CONCLUSION: Acute appendicitis secondary to metastatic disease is uncommon but rarely will be the presenting sign of new cancer diagnosis. Most of the patients have other sites of secondary lesions. Surgical treatment is commonly performed to treat appendicitis.

Surgical management of gallstone ileus after one anastomosis gastric bypass: A case report.

BACKGROUND: Gallstone ileus following one anastomosis gastric bypass (OAGB) is an exceptionally rare complication. The presented case report aims to highlight the unique occurrence of this condition and its surgical management. Understanding the clinical presentation, diagnostic challenges and successful surgical intervention in such cases is crucial for healthcare professionals involved in bariatric surgery. CASE SUMMARY: We present a case report of gallstone ileus following OAGB and discuss its diagnosis and surgical management. A 66-year-old female with a history of OAGB presented to the emergency room with symptoms of small bowel obstruction. Computed tomography scan revealed a gallstone impacted in the distal ileum, causing obstruction. The patient underwent a laparoscopically assisted enterolithotomy, during which the gallstone was extracted and the enterotomy was closed. The patient had an uneventful recovery and was discharged on postoperative day four. CONCLUSION: Gallstone ileus should be considered as a possible complication after OAGB, and prompt surgical intervention is usually required for its management. This case report contributes to the limited existing literature, providing insights into the management of this uncommon complication.

Laparoscopic repair of acquired rectourethral fistula by vesical peritoneal flap.

INTRODUCTION: A rectourethral fistula (RUF) is an infrequent complication that can be iatrogenic in most cases. Multiple surgical interventions were described for RUF repair including transsphincteric, transanal, transperineal, and transabdominal approaches. To this day, there is no consensus on a standardized surgery of choice for acquired RUF. MATERIALS AND SURGICAL TECHNIQUE: Our patient was diagnosed with RUF 4 weeks after undergoing laparoscopic low anterior resection for midrectum adenocarcinoma, with failure of conservative treatment. A three-port transabdominal approach was used to dissect the rectoprostatic space and close the fistula orifice on the anterior rectal wall. With the technical impossibility to develop an omental flap, the peritoneum on the posterior vesical wall was carefully dissected to form a rectangular flap pedicled by its inferior aspect. The harvested peritoneal flap was then anchored between the prostate and the rectum. Follow-up imaging showed the absence of RUF, concurrently with total remission of RUF symptomatology. DISCUSSION: Management of acquired RUF can be challenging, especially after failure of conservative treatment. Laparoscopic repair of acquired RUF by vesical peritoneal flap is a valid option for a minimally invasive approach for the treatment of RUF.

Peri-appendicular Abscess in a Spigelian Hernia.

Background Spigelian hernias are a rare type of lateral ventral abdominal hernia and their content can include any of the intra-abdominal organs. Many cases have described the presence of a variety of abdominal organs in Spigelian hernias, but only few cases report the presence of an incarcerated appendicitis. Imaging is an important step in the diagnosis to avoid the lack of knowledge in such cases. Surgical treatment can be through open or laparoscopic approach, with or without using a mesh according to the size of the defect. Case Report We report a case of an 82-year-old patient who presented with an acute appendicitis with peri-appendicular abscess strangulated in a right Spigelian hernia. The patient was successfully treated by a laparoscopic appendectomy, a surgical drainage of the abscess, and direct muscle approximation without using of mesh due to inflammation. Conclusion Spigelian hernias with acute appendicitis in their content are a very rare condition. Clinical diagnosis is usually difficult and challenging and computed tomography scan is the imaging modality of choice. The treatment is surgical.
