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.

The Role of Obesity in the Poor Prognosis of COVID-19 Infection: A Review of 192 Patients.

Methods: We performed a retrospective study on all patients having COVID-19 infection and admitted to our institution between March 2020 and June 2021. Inclusion criteria included any patient over the age of 18 admitted to our institution's COVID-19 unit, or intensive care unit, with a positive COVID-19 PCR or positive COVID-19 serology (IgM). Results: 192 patients met the inclusion criteria, with an average age of 62.68 years and a slight male predominance (64.58%). 76.04% of hospitalized patients and 80% of those admitted to the ICU were either overweight or obese. No statistically significant difference was found regarding the risk of in-hospital mortality and invasive ventilation. The same applies to the length of stay, admission to intensive care, O2 needs, and for the various complications (all p values were >0.05). Patients with obesity type II and III have an increased risk of cardiac arrests and need for intubation and mechanical ventilation. Conclusion: Obesity tends to be a major risk factor for a pejorative evolution in the COVID-19 infection.

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.

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.

Laparoscopic and robotic multivisceral resection in colorectal cancer: A case series and systematic review.

PURPOSE: Multivisceral resection (MVR) with open approach is the standard surgical treatment for locally advanced colorectal cancer. However, the medical literature concerning the practice of minimally invasive MVR in order to reduce postoperative complications and hospital stay has been growing exponentially over the last years. The present study aimed to examine our experience and to provide a systematic review about the results and complications of minimally invasive MVR. METHODS: Data of patients that underwent minimally invasive MVR for locally advanced colorectal cancer from 2015 to 2021 were retrospectively reviewed. The literature was searched for studies concerning minimally invasive MVR for colorectal cancer. RESULTS: A total of 39 laparoscopic MVR were performed in our department. Complications occurred in 14 patients (35.9%) with major complications in five patients (18.82%) according to Clavien-Dindo classification. Conversion was required in one case (2.56%) with subsequent mortality (2.56%). Pathologic adjacent organs or structures invasion was observed in 30 patients (76.9%) and positive resection margin occurred in two cases (5.2%). Twenty-two studies including 1055 patients were identified after literature search. In these studies, laparoscopic surgery and robotic surgery were performed in 90.15% and 9.85% of the patients, respectively. R0 resection was established in 95% of cases, conversion rate varied between 0% and 41.7%, and postoperative mortality ranged between 0% and 7.7% in the included articles. CONCLUSION: Minimally invasive approach may be a safe option for patients requiring MVR for locally advanced colorectal cancer, with equivalent oncological results and could result in better early postoperative outcomes to open approach. However, further studies on this topic are needed to confirm the results of the current study.

Quality of life after laparoscopic sleeve gastrectomy: Pre-operative, 1-year and 5-year results.

Introduction: The negative impact of obesity on the quality of life (QoL) and its association with multiple comorbidities is unquestionable. The primary objective of this study was to compare the QoL of patients before, 1 year and 5 years after laparoscopic sleeve gastrectomy (LSG). Secondary objectives were to evaluate the resolution of obesity-related comorbidities and weight loss success. Materials and Methods: We included patients who underwent LSG for body mass index (BMI) ≥30 kg/m2 between August 2016 and April 2017 and completed the Moorehead-Ardelt QoL Questionnaire II (MA II). Statistical analysis was conducted using SPSS IBM Statistics for Windows version 21. Results: In total, 64 patients participated with a female majority (73.44%) and a mean age of 36.09 with an average BMI at 40.47. Percentage of excess BMI loss and excess weight loss (% EWL) at one and 5 years after surgery went from 90.18% to 85.05% and 72.17% to 67.09%, respectively. The total MA II score before LSG was - 0.39 ± 0.94. Postoperatively, it increased to 1.73 ± 0.60 at 1 year and 1.95 ± 0.67 at 5 years. The positive impact of LSG on QoL was more significant in patients presenting ≥30% of weight loss and in females. At 5 years, a significant improvement in many comorbidities was noted except for arterial hypertension, coxalgia, gastro-oesophageal reflux disease and lower extremities' varices. Conclusion: LSG maintains a long-term QoL improvement, a significant EWL and a resolution of the most common obesity-associated comorbidities such as diabetes, dyslipidaemia and symptoms related to sleep apnoea.

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.

Obesity: A risk factor for postoperative complications in laparoscopic surgery for colorectal cancer.

Background: The prevalence of obesity in the Eastern Mediterranean is increasing significantly up to 20.8% in 2016. Therefore, a higher percentage of colorectal cancer (CRC) patients are expected to be obese. Laparoscopic colorectal cancer surgery (LCRCS) is regarded as a safe and feasible procedure as laparoscopic approach is becoming the gold standard in CRC surgery, especially in the early stages of disease. However, LCRCS is correlated with a higher risk of short-term post-operative complications in obese patients (body mass index [BMI] ≥30 Kg/m2) than in patients with BMI <30 Kg/m2. This study aims to evaluate the impact of obesity on short-term post-operative complications in patients undergoing LCRCS. Materials and Methods: A retrospective study was conducted. Clinical data of case and control patients were extracted from medical records. These patients underwent LCRCS between January 2018 and June 2021 at Hôtel-Dieu de France Hospital, Beirut-Lebanon. Patients were divided into two groups: obese and non-obese. BMI ≥30 Kg/m2 was used to define obese patients. Post-operative complications in the 30 days following surgery were the primary outcome. The severity of post-operative complications was evaluated using the Clavien-Dindo score. Chi-square test was used to evaluate the statistical correlation between collected variables. Results: We identified 107 patients who underwent LCRCS during this study period at our institution. Among the patients, 23 were obese (21.49%). At 30 days post-operative, 26 patients were reported to having at least one complication. Non-significant differences were found between the two groups regarding the early post-operative complications rate (obese 26.1% and non-obese 23.8% with P = 0.821). Obesity was not demonstrated as a stratification risk by severity of the early post-operative complications (P = 0.92). Conclusion: Obesity, which was defined as BMI ≥30 Kg/m2, was not a risk factor for early post-operative complications as well as a stratification risk by severity of post-operative complications in LCRCS.

The concept of oligometastatic disease in gastric cancer: reality or fiction?

Positive results in the RENAISSANCE Trial will establish oligometastatic gastric cancer as a real independent entity where total surgical treatment will become the standard of care.

Splenic Abscess after Sleeve Gastrectomy.

Splenic abscess is a very rare complication of laparoscopic sleeve gastrectomy (LSG). Clinical presentation includes fever, leucocystosis, and abdominal pain. CT SCAN is a must for diagnosis. The preferred treatment is either conservative, with intravenous antibiotics and percutaneous drainage, or splenectomy. We report the thirteen case of a splenic abscess after LSG. In our patient, the abscess occurred three weeks after LSG in a 21-year-old man, and it was successfully treated conservatively.
