Robotic, transanal, and laparoscopic total mesorectal excision for locally advanced mid/low rectal cancer: European multicentre, propensity score-matched study.

BACKGROUND: Total mesorectal excision (TME) is the standard surgery for low/mid locally advanced rectal cancer. The aim of this study was to compare three minimally invasive surgical approaches for TME with primary anastomosis (laparoscopic TME, robotic TME, and transanal TME). METHODS: Records of patients undergoing laparoscopic TME, robotic TME, or transanal TME between 2013 and 2022 according to standardized techniques in expert centres contributing to the European MRI and Rectal Cancer Surgery III (EuMaRCS-III) database were analysed. Propensity score matching was applied to compare the three groups with respect to the complication rate (primary outcome), conversion rate, postoperative recovery, and survival. RESULTS: A total of 468 patients (mean(s.d.) age of 64.1(11) years) were included; 190 (40.6%) patients underwent laparoscopic TME, 141 (30.1%) patients underwent robotic TME, and 137 (29.3%) patients underwent transanal TME. Comparative analyses after propensity score matching demonstrated a higher rate of postoperative complications for laparoscopic TME compared with both robotic TME (OR 1.80, 95% c.i. 1.11-2.91) and transanal TME (OR 2.87, 95% c.i. 1.72-4.80). Robotic TME was associated with a lower rate of grade A anastomotic leakage (2%) compared with both laparoscopic TME (8.8%) and transanal TME (8.1%) (P = 0.031). Robotic TME (1.4%) and transanal TME (0.7%) were both associated with a lower conversion rate to open surgery compared with laparoscopic TME (8.8%) (P < 0.001). Time to flatus and duration of hospital stay were shorter for patients treated with transanal TME (P = 0.003 and 0.001 respectively). There were no differences in operating time, intraoperative complications, blood loss, mortality, readmission, R0 resection, or survival. CONCLUSION: In this multicentre, retrospective, propensity score-matched, cohort study of patients with locally advanced rectal cancer, newer minimally invasive approaches (robotic TME and transanal TME) demonstrated improved outcomes compared with laparoscopic TME.

Laparoscopic management of gastric perforation secondary to mesenteroaxial volvulus in a patient with laparoscopic adjustable gastric banding.

A 54-year-old woman was admitted to the emergency department with a 2-week history of alimentary vomiting. She had undergone laparoscopic adjustable gastric banding 6 years earlier. CT revealed a mesenteroaxial gastric volvulus and ischemia on the gastric wall. Emergent diagnostic laparoscopy was performed, and severe peritonitis and gastric necrosis caused by volvulation was found. After band removal, a fundal perforation was noted, but a viable lesser curvature enabled laparoscopic sleeve gastrectomy to be performed. The postoperative course was uneventful. Laparoscopic adjustable gastric banding is considered a safe and effective method for the surgical treatment of obesity, but it is associated with a number of complications, such as pouch dilatation and band slippage. Although infrequent, ischemic complications are life-threatening conditions that require urgent surgery. This is the first report of this unusual complication managed laparoscopically.

Short- and Long-Term Effects of Weight Loss on the Complement Component C3 After Laparoscopic Gastric Bypass in Obese Patients.

BACKGROUND: The C3 complement component (C3c) is increasingly recognized as a cardiometabolic risk factor, but how it is affected after weight loss through gastric bypass is a question yet to be answered. METHODS: A total of 66 obese patients underwent laparoscopic gastric bypass. Anthropometric parameters, total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc), glucose, insulin, HOMA-IR, liver enzymes, high-sensitivity C-reactive protein (hsCRP), and C3c levels were evaluated at baseline and at 1 and 5 years post-surgery. RESULTS: All anthropometric and biochemical parameters improved significantly after surgery, although a deterioration was detected with respect to the percentage of excess of weight loss, insulin, TC, LDLc, and lactate dehydrogenase 5 years post-surgery. Despite this, a remission rate of 84 % was observed in the presence of metabolic syndrome after 5 years follow-up. hsCRP and C3c were reduced significantly after surgery and maintained throughout the experimental period. In addition, C3c was correlated with BMI and insulin at all time points. The multivariate regression model, in which C3c was a dependent variable, revealed that aspartate aminotransferase and BMI were independent variables at baseline, alkaline phosphatase and insulin were independent at 1 year post-surgery, and insulin, BMI, and TC were independent at 5 years post-surgery. CONCLUSIONS: C3c may be a marker of the chronic inflammatory process underlying insulin resistance. Its association with BMI and liver enzymes supports a major role in metabolic activity, although future research is needed to clarify the nature of the molecular mechanisms involved and the physiological significance of these findings.

Assisted laparoscopic transhiatal esophagectomy for the treatment of esophageal cancer.

BACKGROUND: Esophageal resection for the treatment of esophageal cancer is usually associated with high morbido-mortality risks, that can be reduced using laparoscopy. Laparoscopic transhiatal esophagectomy (LTE) has the potential to improve these results but, to-date, only a few limited series of cases have been reported. This report summarizes our experience in 24 cases. OBJECTIVE: To assess the outcomes following LTE. METHODS AND MATERIALS: Between 1998 and 2005, LTE was performed in 24 patients; 18 men and 6 women with an overall mean age of 63 years (range: 36-85). Indication for surgery was lower third esophageal cancer; 11 squamous cell carcinoma and 13 adenocarcinoma. Neoadjuvant chemotherapy and radiotherapy were used in 18 patients (75%). A laparoscopic transhiatal approach was used to perform an esophagectomy with curative intent. A cervical esophagogastric anastomosis was created. RESULTS: No reversion to conventional open surgery was required. Mean anesthesia time was 293.8 min (range: 255-360). Major complications occurred in 7 patients (29.2%). Two patients (8.3%) had leakage from the cervical anastomosis. Surgical mortality was 8.3%. The median stay in Intensive Care Unit was 5 days (range: 1-29). Median hospital stay was 11.5 days (range: 7-54). At a mean follow-up of 24.9 months, 8 patients (36.4%) had disease recurrence (36.4%), global survival rate was 62.5%, and diseasefree survival rate was 50%. CONCLUSIONS: Assisted laparoscopic transhiatal esophagectomy for lower third esophageal cancer is a potentially safe and effective method when performed by surgeons with expertise in the field. Benefits from this approach need to be confirmed by further randomized studies.

The role of ultrasound in the diagnosis, management and evolutive prognosis of acute left-sided colonic diverticulitis: a review of 208 patients.

The aim of this study was to evaluate the role of ultrasound in the diagnosis and management of acute diverticulitis and its capacity to predict posterior complications in patients undergoing medical treatment. A review was made of the histories of 208 hospitalized patients (262 admissions) initially diagnosed with acute diverticulitis over a 5-year period. Ultrasound was performed in all patients upon first admission. Diverticulitis was retrospectively classified as either simple or complicated, the latter being defined by the presence of extraluminal air and/or abscesses. Diverticulitis was finally diagnosed in 203 patients. Ultrasound exhibited a sensitivity of 86% in 77 cases subjected to surgery, and of 94% in the global 203 patients (192 true-positive and 11 false-negative findings). Of 34 patients with diverticulitis and emergency surgery, 10 had false-negative US exams. Twenty of the 73 cases (27%) with signs of complicated diverticulitis in the initial ultrasound study required emergency surgery, compared with only 4 of the 119 patients (3%) with US evidence of simple diverticulitis (p<0.001). Of the 169 patients with diverticulitis undergoing conservative management, 54 (32%) developed complications during follow-up. The patients under age 50 years with signs of complicated diverticulitis suffered more complications (65%) than the rest of groups (p<0.001). In subjects with recurrences (26%), these were either similar to or less than the first episode in 84% of the cases. The present study shows that ultrasound constitutes a feasible technique for diagnosing acute diverticulitis. The severity of diverticulitis according to US is statistically predictive of surgical risk during the acute phase. Severity is also related to the appearance of posterior complications in patients undergoing conservative management, although only in younger patients (<50 years).
