RESUMO
Preoperative transfusion (PT) reduces acute postoperative vaso-occlusive events (VOE) in sickle cell disease (SCD), but exposes patients to alloimmunization, encouraging a recent trend towards transfusion sparing. The aim of this study was to investigate the benefit-risk ratio of PT before cholecystectomy on the occurrence of postoperative VOE. Adult SCD patients who underwent cholecystectomy between 2008 and 2019 in our center were included. Patients' characteristics, collected retrospectively, were compared according to PT. A total of 79 patients were included, 66% of whom received PT. Gallbladder histopathology found chronic cholecystitis (97%) and gallstones (66%). Transfused patients underwent more urgent surgeries and had experienced more painful vaso-occlusive crises (VOC) in the month before surgery (p = 0.05). Four (8.5%) post-transfusion alloimmunizations occurred, and two of them caused a delayed hemolytic transfusion reaction (DHTR) (4.3%). The occurrence of postoperative VOE was similar between the groups (19.2% vs. 29.6%, p = 0.45). Though not statistically significant, a history of hospitalized VOC within 6 months prior to surgery seemed to be associated to postoperative VOE among non-transfused patients (75% vs. 31.6%, p = 0.10). PT before cholecystectomy exposes to risks of alloimmunization and DHTR that could be avoided in some patients. Recent VOCs appear to be associated with a higher risk of postoperative VOE and prompt the preemptive transfusion of these patients.
RESUMO
In the world, among all type of cancers, colorectal cancer (CRC) is the third most commonly diagnosed in males and the second in females. In most of cases, (RP1) patients' prognosis limitation with malignant tumors can be attributed to delayed diagnosis of the disease. Identification of patients with early-stage disease leads to more effective therapeutic interventions. Therefore, new screening methods and further innovative treatment approaches are mandatory as they may lead to an increase in progression-free and overall survival rates. For the last decade, the interest in extracellular vesicles (EVs) research has exponentially increased as EVs generation appears to be a universal feature of every cell that is strongly involved in many mechanisms of cell-cell communication either in physiological or pathological situations. EVs can cargo biomolecules, such as lipids, proteins, nucleic acids and generate transmission signal through the intercellular transfer of their content. By this mechanism, tumor cells can recruit and modify the adjacent and systemic microenvironment to support further invasion and dissemination. This review intends to cover the most recent literature on the role of EVs production in colorectal normal and cancer tissues. Specific attention is paid to the use of EVs for early CRC diagnosis, follow-up, and prognosis as EVs have come into the spotlight of research as a high potential source of 'liquid biopsies'. The use of EVs as new targets or nanovectors as drug delivery systems for CRC therapy is also summarized.
RESUMO
BACKGROUND: In colon cancer (CC), surgery remains the mainstay of treatment with curative intent. Despite several clinical trials comparing open and laparoscopic approaches, data on long-term outcomes for stage III CC are lacking. METHODS: This post-hoc analysis of the European PETACC8 randomized phase 3 trial included patients from 340 sites between December 2005 and November 2009, with long follow-up (median 7.56 years). Patients were randomly assigned to FOLFOX or FOLFOX+cetuximab after colonic resection. The surgical approach was left to the referring surgeon's discretion. RESULTS: Among 2555 patients included, 1796 (70.29%) were operated on by open surgery and 759 (29.71%) by laparoscopy. The 5-year OS rate was better after laparoscopic resection (85.4%, 95%CI 82.5-87.7) than after open surgery (80.2%, 95%CI 78.2-82.0; p = 0.002). The 5-year DFS rate was also better after laparoscopy (p = 0.016). However, in multivariate analysis using a propensity matching, the surgical approach was not found to be an independent prognostic factor for OS or DFS. OS (p = 0.0243) and DFS (p = 0.035) were increased after laparoscopic surgery in KRAS/BRAF WT sub-group CONCLUSION: We showed that laparoscopic resection has comparable long-term outcomes to open surgery in patients with stage III CC. For those with RAS and BRAF WT CC, laparoscopic colectomy may favorably impact survival.

People suffering from extreme obesity may be exposed to delayed diagnosis and treatment of cancer. A 37-year-old woman (weight = 245 kg, body mass index (BMI) = 79 kg/m2), presented a sepsis associated with nonspecific abdominal pain for 4 months. After several unsuccessful attempts due to her weight and a large waist circumference, abdominal CT scan was finally successfully performed and showed a large retroperitoneal mass. An ultrasound-guided core needle biopsy was performed and was in favor of a liposarcoma. Surgery was performed to remove the entire tumor of an estimated weight of 98 kg, a giant retroperitoneal dedifferentiated liposarcoma. This case highlights the difficulties to screen, diagnose, and manage cancers encountered in patients suffering from massive obesity.

BACKGROUND: The Bacillus Calmette-Guerin (BCG) is a life-attenuated form of Mycobacterium bovis widely used as immunotherapy for localized bladder cancer. Adverse reactions to intravesical BCG instillations are rare. CASE: We describe a 70-year-old man with a history of an aortobifemoral bypass graft, placement of a synthetic mesh for treatment of a ventral hernia and, most recently, superficial bladder cancer treated with BCG therapy. Ten months after his final intravesical BCG instillation, he complained of fever and asthenia. After 12 months of investigation, he was diagnosed with Mycobacterium bovis infection of his aortobifemoral bypass graft and abdominal mesh, with Streptococcus intermedius superinfection. The bypass graft was excised and replaced with an in situ arterial allograft, the abdominal mesh was removed, and treatment started with amoxicillin, isoniazid, rifampicin and ethambutol. Several additional vascular interventions were needed for allograft degradation, but 12 months after the final procedure, outcome was good. DISCUSSION AND CONCLUSIONS: Among 35 cases of mycotic aneurysm reported after BCG therapy in the last 10 years, only one involved a vascular prosthesis. Surgical repair of such aneurysms using prosthetic grafts is commonly performed, associated with anti-mycobacterial treatment. Prognosis is poor with mortality of 14% (4/35) and a 26% rate of aneurysm recurrence under treatment (9/35).

The most dreadful complication after sleeve gastrectomy (SG) is staple line leak. Its rate varies between 1 and 2%. With the development of interventional endoscopy, its treatment is currently fairly standardized and allows healing in the majority of cases without revisional surgery. However, if endoscopic treatment fails, surgical treatment becomes unavoidable. Fistulojejunostomy is a surgical option in the management of chronic fistula after SG. Laparoscopic fistulojejunostomy in a patient with chronic fistula after SG is difficult but feasible. This procedure allows complete healing and nutritional recovery in the case of failure of other endoscopic modalities.

BACKGROUND: One-anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) remains controversial because it may cause chronic biliary reflux (BR). The risk of developing esogastric cancer due to BR after OAGB/MGB is based on the results of experimental rat studies using esojejunostomy (EJ). The aim of this study was to analyze the potential long-term consequences of BR on the esogastric mucosae in OAGB/MGB-operated rats and to compare these results to those from the use of EJ. METHODS: Wistar rats received OAGB/MGB (n = 16), EJ (n = 16), and sham (n = 8) operations. Mortality and weight changes were evaluated throughout the experiment. BR was measured using magnetic resonance imaging (MRI). Rats received follow-ups for 30 weeks. A double-blinded histological analysis was performed in the esogastric segments. RESULTS: BR was diagnosed in OAGB/MGB and EJ rats using the MRI technique; no BR occurred in the sham group. After a 30-week follow-up, no incidences of dysplasia or cancer were observed in the three groups. Additionally, esophageal intestinal metaplasia and mucosal ulcerations were observed in 41.7% and 50% of EJ rats, respectively, and no incidences of these conditions were observed in OAGB/MGB and sham rats. The incidence of esophagitis was significantly higher and more severe in the EJ group compared to those in the OAGB/MGB and sham groups (EJ = 100%, OAGB/MGB = 16.7%, sham = 8.3%; p < 0.001). CONCLUSIONS: After a 30-week follow-up period, OAGB/MGB rats did not develop any precancerous or cancerous lesions when more than 40% of EJ rats had intestinal metaplasia.

In some cases, in addition to the usual difficulties that the bariatric surgeon may encounter during standard bariatric procedures, anatomical anomalies such as situs inversus can pose an additional technical challenge. A 58-year-old patient with total situs inversus underwent Roux-en-Y gastric bypass (RYGB) surgery in our department. The main difficulty was the realization of a mirrored RYGB. Laparoscopic RYGB in a patient with situs inversus totalis is feasible but requires significant concentration and three-dimensional coordination to perform the mirrored procedure.

PURPOSE: During right-sided colectomies, surgeons encounter major anatomical variations at the level of the right colon, leading to morbidity. Due to the confusion surrounding the colonic arterial vessels emerging from the superior mesenteric artery (SMA) to vascularize the right part of the colon, this review aimed to describe the arterial vessels found in the mesocolic structures of the ascending colon, the hepatic flexure and the right transverse colon. METHODS: A review of the literature was performed using the MEDLINE database. Only human studies were included. All dissection, angiographic, arterial cast and corrosion studies were analyzed. RESULTS: This review demonstrates that the right colon, the hepatic flexure and the right transverse colon are vascularized by three significant arteries emerging from the SMA and forming one peripheral paracolic arc: (1) the ileocolic artery (ICA), the most constant vessel (99.8%) with low variability; (2) the right colic artery (RCA), the most inconstant vessel (2/3 of cases) with high variability in its origin; and (3) the middle colic artery (MCA), a constant vessel (95%) with variation in its origin and its number. The marginal artery is almost constant (100%) and represents the only peripheral arterial arc at the level of the right side of the colon. CONCLUSIONS: Three arteries emerging from the superior mesenteric artery exist: the ICA, the RCA and the MCA. The ICA and the MCA are the most constant. Knowledge of this vascular anatomy is essential for performing right-sided colectomies.

PURPOSE: Gastric fistula is a severe complication following sleeve gastrectomy (SG). Chronic gastric fistula can progress to complex anatomical situations, such as esogastro-bronchial and/or esogastro-pleural (EGBP) fistulas. We decided to analyze the anatomical characteristics of these EGBP fistulas after SG. METHODS: Our work consisted of an analysis of the clinical, endoscopic, and radiological data of patients treated for EGBP fistulas after SG at the Georges Pompidou European Hospital from May 2009 to November 2017. RESULTS: A total of 11 patients were retrospectively included with available complete clinical, endoscopic, and radiological data. The origin of the fistula was mostly at the top of the staple line. The fistula's termination was pleural in 5 patients (45%) and bronchial in 6 (55%). In bronchial fistulas, 2 were proximal and 4 were distal, with the left pulmonary posterolateral segment (S10) being reached in each case. The trans-diaphragmatic passage was through the left cupola in 9 out of 11 patients (82%). In 2 patients, the passage was trans-hiatal (18%). Interestingly, the 2 eso-bronchial fistulas had a trans-hiatal passage with a termination in the proximal bronchus, while the 4 gastro-bronchial fistulas had a trans-diaphragmatic passage with a termination in the distal bronchus. All pleural fistulas were gastric with a trans-diaphragmatic passage. CONCLUSIONS: Esogastro-bronchial and gastro-pleural fistulas after SG originated mostly at the top of the staple line. Eso-bronchial fistulas had a trans-hiatal passage with a proximal bronchial termination, while gastro-bronchial fistulas had a trans-diaphragmatic passage with a distal bronchial termination.

INTRODUCTION: One anastomosis gastric bypass (OAGB) was suggested as an option in the management of weight loss failure after sleeve gastrectomy (SG). In parallel, the length of the biliopancreatic limb (BPL) is currently debated. OBJECTIVES: To evaluate morbidity and efficiency of the conversion of SG to OAGB using two lengths of BPL (150 cm versus 200 cm). METHODS: Retrospective analysis of a prospectively collected database on 72 patients operated on between 2007 and 2017: (200-cm BPL before 2014 versus 150-cm BPL since 2014). RESULTS: At revision, the mean body mass index (BMI) was 43.6 ± 7 kg/m2. Sixteen patients (20%) had type 2 diabetes (T2D) and 23 (29%) had obstructive sleep apnea (OSA). Early morbidity rate was 4.2% (n = 3). Mean BMI were 33.7 ± 6 and 34.8 ± 9 at 2 and 5 years, respectively. At 5 years, the rate of lost of follow-up was 34%. T2D and OSA improved in 80% (n = 12) and 70% (n = 16) of the patients, respectively. At revision, the mean BMI were 46 ± 8 kg/m2 and 41 ± 6 kg/m2 for patients with 200-cm BPL (n = 38) and 150-cm BPL (n = 34), respectively. Two years after conversion, the mean BMI were 34 ± 1 kg/m2 for 200-cm BPL and 32 ± 7 kg/m2 for 150-cm BPL. The rate of gastroesophageal reflux disease (GERD) and diarrhea was 13% and 5% in patients with 200-cm BPL versus 3% and 0% in patients with 150-cm BPL. CONCLUSION: This study shows that the conversion of SG to OAGB is feasible and safe allowing significant weight loss and improvement in comorbidities. Weight loss seems comparable between the 150-cm and 200-cm BPL.

BACKGROUND: Ampullary adenocarcinoma (AA) originates from either intestinal (INT) or pancreaticobiliary (PB) epithelium. Different prognostic factors of recurrence have been identified in previous studies. METHODS: In 91 AA patients of the AGEO retrospective multicentre cohort, we evaluated the centrally reviewed morphological classification, panel markers of Ang et al. including CK7, CK20, MUC1, MUC2 and CDX2, the 50-gene panel mutational analysis, and the clinicopathological AGEO prognostic score. RESULTS: Forty-three (47%) of the 91 tumours were Ang-INT, 29 (32%) were Ang-PB, 18 (20%) were ambiguous (Ang-AMB) and one could not be classified. Among these 90 tumours, 68.7% of INT tumours were Ang-INT and 78.2% of PB tumours were Ang-PB. MUC5AC expression was detected in 32.5% of the 86 evaluable cases. Among 71 tumours, KRAS, TP53, APC and PIK3CA were the most frequently mutated genes. The KRAS mutation was significantly more frequent in the PB subtype. In multivariate analysis, only AGEO prognostic score and tumour subtype were associated with relapse-free survival. Only AGEO prognostic score was associated with overall survival. CONCLUSIONS: Mutational analysis and MUC5AC expression provide no additional value in the prognostic evaluation of AA patients. Ang et al. classification and the AGEO prognostic score were confirmed as a strong prognosticator for disease recurrence.

BACKGROUND/AIMS: This study aims to describe the autonomic nervous network of the female pelvis with a 3D model and to provide a safe plane of dissection during radical hysterectomy for cervical cancer. METHODS: Pelvises of 3 human female fetuses were studied by using the computer-assisted anatomic dissection. RESULTS: The superior hypogastric plexus (SHP) was located at the level of the aortic bifurcation in front of the sacral promontory and divided inferiorly and laterally into 2 hypogastric nerves (HN). HN ran postero-medially to the ureter and in the lateral part of the uterosacral ligament until the superior angle of the inferior hypogastric plexus (IHP). IHP extended from the anterolateral face of the rectum, laterally to the cervix and attempted to the base of the bladder. Vesical efferences merged from the crossing point of the ureter and the uterine artery and ran through the posterior layer of the vesico-uterine ligament. CONCLUSIONS: The SHP could be injured during paraaortic lymphadenectomy. Following the ureter and resecting the medial fibrous part of the uterosacral ligament may spare the HN. No dissection should be performed under the crossing point of the ureter and the uterine artery.

BACKGROUND: Anastomotic leakage (AL) is a potential feared complication after colorectal resection, which is associated with an increased risk of postoperative mortality and frequently requires additional surgery. The aim of this study was to assess major independent risk factors for AL after elective colonic resection for cancer, including anastomotic location. METHODS: Among 1940 consecutive patients referred to our institution for colorectal adenocarcinoma, 1025 patients had elective colonic resection with intraperitoneal anastomosis without diverting stoma. Risk factors were assessed among preoperative, operative, and histological data. RESULTS: Clinical AL was observed in 36 patients (3.5%) with 24 patients requiring revisional surgery (67%). In multivariate analysis, endoscopic impassable tumor and colo-colic or ileo-colic anastomosis were independent risk factors for AL. The occurrence of AL was associated with poor overall (43.1 months vs. 146.4 months; p < 0.001) and disease-free survival (40.5 months vs. 137.3 months; p = 0.003). CONCLUSION: Anastomotic leakage occurs more frequently after colo-colic and ileo-colic anastomosis than after intraperitoneal colorectal anastomosis. The right colectomy appears to be at higher risk of AL, with a greater risk of surgical intervention than after an elective left colectomy. Ileo-colic anastomosis should be avoided in cases of suboptimal conditions.

Complicated Meckel's diverticulum represents a common etiology of acute abdomen in children. However, this condition is less frequent in adults. We reviewed the records of adult patients who underwent the surgical removal of complicated Meckel's diverticulum between 2001 and 2017 at 2 tertiary French medical centers. We then analyzed the clinical characteristics, mode of presentation, and management for all patients.The Meckel's diverticulum was resected in 37 patients (24 males and 13 females). The mean patient age was 46.1â±â21.4 years. The most common clinical presentations of complicated Meckel's diverticulum were diverticulitis (35.1%, nâ=â13), small-bowel obstruction (35.1%, nâ=â13), and gastrointestinal bleeding (29.8%, nâ=â11) (anemia, nâ=â1; hematochezia, nâ=â10). Age distribution was significantly different (Pâ=â.02) according to the 3 Meckel's diverticulum complications: patients with diverticulitis (Pâ=â.02) were statistically more frequently over 40 (Pâ=â.05), significantly older than patients with gastrointestinal bleeding who were more frequently <40 (Pâ=â.05). There was a preoperative diagnosis available for 15 of the 37 patients (40%). An exploratory laparoscopy was necessary to determine the cause of disease for the other 22 patients (60%). An intestinal resection was performed in 33 patients (89%) and diverticulectomy was performed in 4 patients (11%). There was heterotopic tissue found in only 6 patients (16%). Postoperative complications were as follows: 1 death by cardiac failure in a 92-year-old patient and 2 patients with postoperative wound infections. The follow-up time was 3 to 12 months.The correct diagnosis of complicated Meckel's diverticulum in adults is difficult due to the lack of specific clinical presentation. As a result, exploratory laparoscopy appears to play a central role in cases of acute abdomen with uncertain diagnosis.

BACKGROUND AND STUDY AIMS: Post-laparoscopic sleeve gastrectomy (LSG) fistula is a major complication, responsible for high morbidity. Endoscopic treatment represents an alternative to surgical management, with variable approaches and success rates. In this study, we aimed to evaluate the efficacy of endoscopic treatment in a tertiary care center. PATIENTS AND METHODS: Between March 2010 and March 2015, all patients referred to our center for endoscopic treatment of fistula related to laparoscopic sleeve gastrectomy were included. The primary endpoint was defined as a complete closure of the fistula without recurrence within the 2 months. RESULTS: A total of 26 patients were retrospectively included (73% female). The mean time between fistula diagnosis and first endoscopy was 27.4 days (± 22). Twenty-three (88.4%) patients had a complete fistula closure after endoscopic treatment. The healing delay was 76.4 days (± 42.8), and an average of 3.5 (± 1.4) endoscopic procedures were required. Clinical efficacy was 100% when the endoscopic treatment was performed within the first 3 weeks, or 70% afterwards (p = 0.046). The fistula closure rate was similar between patients with endoscopic drainage (with or without other endoscopic techniques) and patient with closing techniques alone (85.7% vs. 89.5%, respectively). CONCLUSION: Endoscopic treatment of fistula after LSG is efficient but requires early procedures within the first 3 weeks. Endoscopic strategies involving closing procedure or drainage procedure seem to be similar, but these data must be confirmed in large prospective clinical studies.

PURPOSE OF REVIEW: Morbid obesity and type-2 diabetes mellitus (T2DM) are both major public health problems. Bariatric surgery is a proven and effective treatment for these conditions; laparoscopic Roux-en-Y gastric bypass (RYGB) is currently the gold-standard treatment. One-anastomosis gastric bypass (OAGB) is described as a simpler, safer, and non-inferior alternative to RYGB to treat morbid obesity. Concerning T2DM, experts of the OAGB procedure report promising metabolic results with good long-term remission of T2DM; however, heterogeneity within the literature prompted us to analyze this issue. RECENT FINDINGS: OAGB has gained popularity given its safety and long-term efficacy. Concerning the effect of OAGB for the treatment of T2DM, most reports involve non-controlled single-arm studies with heterogeneous methodologies and a few randomized controlled trials. However, this available literature supports the efficacy of OAGB for remission of T2DM in obese and non-obese patients. Two years after OAGB, the T2DM remission and improvement rate increased from 67 to 100%. The results were improved and stable in the long term. The 5-year T2DM remission rate increased from 82 to 84.4%. OAGB is non-inferior compared with RYGB and even superior to other accepted bariatric procedures, such as sleeve gastrectomy and adjustable gastric banding. OAGB is an efficient, safe, simple, and reversible procedure to treat T2DM. The literature reveals interesting results for T2DM remission in non-obese patients. High-level comparative studies are required to support these data.

BACKGROUND: Leakage after one-anastomosis gastric bypass (OAGB) is fortunately rare (<1%), but it remains the most severe complication. Few published data exist on this specific issue. OBJECTIVES: To analyze the results from patients who presented with acute intra-abdominal sepsis (AIAS) caused by leakage after OAGB. SETTING: A university public hospital in France. METHODS: Between October 2006 and February 2016, 17 consecutive patients with a diagnosis of AIAS caused by leakage after OAGB were included. Preoperative characteristics, clinical symptoms, radiologic findings, management, morbidity, and mortality were assessed. RESULTS: All 17 patients were included in the study. There were 4 men (23.5%), the median age was 48 years, and median preoperative body mass index (BMI) was 51 kg/m2. The most frequent clinical sign was tachycardia (65%). An oral contrast computed tomography scan was performed in 15 patients (88%) and showed a diagnosis of AIAS in 93% of cases. The median time between OAGB and leak diagnosis was 4 days. A gastrojejunal anastomosis (GJA) leak was the most frequent origin (41%). Sixteen patients (94%) were managed surgically (laparotomy n = 11, laparoscopy n = 5) and one medically. There were no deaths. The overall morbidity rate was 47% (major = 41%). Six patients underwent an emergency conversion into Roux-en-Y gastric bypass (RYGB) (in cases of GJA, gastric-tube, and biliary-limb leakages) and were compared to 6 patients who did not undergo conversion but who could have benefited. We observed a tendency toward a reduced overall morbidity rate (16.7% versus 83.3%, P = .08) and shorter lengths of stay in the "conversion to RYGB" group. CONCLUSION: The management of AIAS caused by leakage after OAGB was safe, effective, and mostly surgical. Emergency conversion to RYGB in cases of GJA, gastric-tube, or biliary-limb perforation was feasible and safe.
