Robotic surgery for inguinal and ventral hernia repair: a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis assessed the effectiveness of robotic surgery compared to laparoscopy or open surgery for inguinal (IHR) and ventral (VHR) hernia repair. METHODS: PubMed and EMBASE were searched up to July 2022. Meta-analyses were performed for postoperative complications, surgical site infections (SSI), seroma/hematoma, hernia recurrence, operating time (OT), intraoperative blood loss, intraoperative bowel injury, conversion to open surgery, length of stay (LOS), mortality, reoperation rate, readmission rate, use of opioids, time to return to work and time to return to normal activities. RESULTS: Overall, 64 studies were selected and 58 were used for pooled data analyses: 35 studies (227 242 patients) deal with IHR and 32 (158 384 patients) with VHR. Robotic IHR was associated with lower hernia recurrence (OR 0.54; 95%CI 0.29, 0.99; I2: 0%) compared to laparoscopic IHR, and lower use of opioids compared to open IHR (OR 0.46; 95%CI 0.25, 0.84; I2: 55.8%). Robotic VHR was associated with lower bowel injuries (OR 0.59; 95%CI 0.42, 0.85; I2: 0%) and less conversions to open surgery (OR 0.51; 95%CI 0.43, 0.60; I2: 0%) compared to laparoscopy. Compared to open surgery, robotic VHR was associated with lower postoperative complications (OR 0.61; 95%CI 0.39, 0.96; I2: 68%), less SSI (OR 0.47; 95%CI 0.31, 0.72; I2: 0%), less intraoperative blood loss (- 95 mL), shorter LOS (- 3.4 day), and less hospital readmissions (OR 0.66; 95%CI 0.44, 0.99; I2: 24.7%). However, both robotic IHR and VHR were associated with significantly longer OT compared to laparoscopy and open surgery. CONCLUSION: These results support robotic surgery as a safe, effective, and viable alternative for IHR and VHR as it can brings several intraoperative and postoperative advantages over laparoscopy and open surgery.

Surgical management of parastomal hernia following radical cystectomy and ileal conduit: A french multi-institutional experience.

BACKGROUND: Parastomal incisional hernia (PH) is a frequent complication following the creation of an ileal conduit (IC), and it can be a significant detriment to quality of life. The aim of this study was to evaluate outcomes of PH repair following IC for urinary diversion. METHOD: A multicenter retrospective study was conducted of 6 academic hospitals in France. The study's population included patients who underwent surgical treatment for parastomal hernia following IC creation from 2013 to 2021. RESULTS: Fifty-one patients were included in the study. Median follow up was 15.3 months. Eighteen patients presented with a recurrence (35%), with a median time to recurrence of 11.1 months. The vast majority of PH repair was performed through an open approach (88%). With regard to technique, Keyhole was the most reported technique (46%) followed by Sugarbaker (22%) and suture only (20%). The Keyhole technique was associated with a higher risk of recurrence compared to the Sugarbaker technique (52% vs 10%, p = 0.046). Overall, there was a 7.8% rate of major complications without a statistical difference between PH repair techniques for major complications. CONCLUSION: Surgical treatment of parastomal hernia following IC was associated with a high risk of recurrence. Novel surgical approaches to PH repair should be considered.

Endoscopic Follow-Up Between 3 and 7 Years After Sleeve Gastrectomy Reveals Antral Reactive Gastropathy but no Barrett's Esophagus.

BACKGROUND: The main concerns following sleeve gastrectomy (SG) include the risk of gastroesophageal reflux disease (GERD) and its complications, such as Barrett's esophagus (BE). However, there is conflicting data on esophageal conditions, and studies on alterations of gastric mucosa after SG are lacking, despite reported cases of gastric cancer. Our aim was to assess esophageal and gastric lesions after SG. METHODS: From November 2017, an upper gastrointestinal endoscopy (UGE) was proposed at least 3 years after SG to all patients operated on in our institution. Endoscopic results and gastric histological findings were analyzed. BE was defined as endoscopically suspected esophageal metaplasia with histological intestinal metaplasia. RESULTS: Between September 2008 and August 2018, 375 patients underwent SG at our institution, of which 162 (43%) underwent at least one UGE 3 years or more after SG (91% women, mean preoperative age: 43.3±10.3 years). Despite a significant increase in the prevalence of symptomatic GERD, hiatal hernia, and esophagitis after SG (p<0.001 vs. preoperatively), no cases of BE were detected. Gastric dysplasia was not found and the prevalence of gastric atrophy tended to decrease after SG. However, 27% of patients with gastric biopsies developed antral reactive gastropathy. CONCLUSIONS: At a mean follow-up of 54 months after SG, no BE or gastric dysplasia was identified. However, reactive gastric lesions appeared, and their long-term consequences need to be further clarified. Thus, the timing of endoscopic follow-up, starting as early as 3 years after SG should be reevaluated to improve patient adherence with long-term endoscopies.

Efficacy and safety of endoscopic pyloric balloon dilation in patients with refractory gastroparesis.

BACKGROUND AND AIMS: There has been interest in the use of pyloric therapies for the treatment of refractory gastroparesis. However, data on endoscopic pyloric dilation are scarce. We aimed to assess the efficacy and safety of this procedure in refractory gastroparesis. METHODS: We performed a retrospective analysis of 47 patients referred for refractory gastroparesis, confirmed by gastric emptying scintigraphy, and treated with endoscopic pyloric through-the-scope balloon dilation. The primary endpoint was the effectiveness of the procedure, evaluated with the Gastric Cardinal Symptom Index (GCSI) at 2 and 6 months. RESULTS: A clinical response, defined by a 1.0 point decrease in the GCSI score, was observed in 25 patients at 2 months (53%) and in 19 patients at 6 months (40%). The mean GCSI score decreased significantly at 2 and 6 months compared to the preoperative score (3.9 ± 0.87 vs 2.3 ± 1.37 and 3.9 ± 0.87 vs 2.9 ± 1.27, respectively; p < 0.0001). No complication was observed. Nine patients had a delayed relapse at 1 year. A second dilation was performed for eight patients and it was effective in five of them (63%). The mean follow-up time of the patients was 27.0 ± 10.4 months. At 2 years, 15 patients still experienced improvement following this treatment (32%). No predictive factor of clinical response was identified. CONCLUSION: The efficacy of pyloric dilation is 53% at 2 months, with sustained improvement in one third of patients at 2 years. This treatment should be considered as an alternative option to pyloromyotomy.

Roux-en-Y gastric bypass as a salvage solution for severe and refractory gastroparesis in malnourished patients.

BACKGROUND: Gastroparesis (GP) is a rare condition for which several symptomatic treatments are available, but they may fail, leading to a discussion of gastrectomy. Few studies have described gastric-preserving surgery, particularly in malnourished patients. OBJECTIVE: To describe the treatment of severe refractory GP with Roux-en-Y gastric bypass (RYGB). SETTING: A university center. METHODS: A retrospective review was conducted of adult patients who underwent laparoscopic RYGB. Severity and frequency of GP symptoms were compared before and 1 year after surgery using the Gastroparesis Cardinal Symptom Index (GCSI) score (0-5), the vomiting (VM) score (0-4), and the visual analog scale (VAS) for abdominal pain. RESULTS: Of the 9 patients with refractory GP, 7 were malnourished and 2 had obesity. There were no postoperative deaths. One patient was operated on for internal hernia without bowel necrosis. The mean GCSI score decreased significantly from 3.6 (range: 1-5) preoperatively to 2.1 (range: .3-4.4) postoperatively (P = .0019). The mean VM score improved significantly after surgery, from .22 (range: 0-1 units) preoperatively to 2.55 (range: 1-4) postoperatively (P = .007). The mean VAS score also decreased significantly from 7.0 (range: 5-9) preoperatively to 2.44 (range: 0-7) postoperatively (P = .0015). A nonsignificant weight and albumin change was observed at 1 year postoperatively, with a tendency for weight regain in malnourished patients. CONCLUSION: In malnourished patients with severe and refractory GP, this study suggests the feasibility, safety, and efficacy of RYGB for the treatment of vomiting and abdominal pain.

Seventy years of bariatric surgery: A systematic mapping review of randomized controlled trials.

While research publications on bariatric surgery (BS) have grown significantly over the past decade, there is no mapping of the existing body of evidence on this field of research. We performed a systematic review followed by a mapping of randomized controlled trials (RCTs) in BS for people with obesity. From January 2020 to December 2020, we performed a systematic review of RCTs evaluating BS, versus another surgical procedure, or versus a medical control group, through a search of Embase and PubMed. There was no restriction on outcomes for study selection. A total of 114 RCTs were included, most (73.7%) of which were based on a comparison with Roux-en-Y gastric bypass (RYGB) and conducted between 2010 and 2020. Only 15% of the trials were multicenter and few (3.5%) were international. The median number of patients enrolled was 61 (interquartile range [IQR]: 47.3-100). Follow-up time was 1 to 2 years in 36% and 22.8% of the trials, respectively. Weight loss was the most studied criterion (87% of RCTs), followed by obesity-related diseases, and medical and surgical complications (73%, 54%, and 47% of RCTs, respectively). Nutritional deficiency frequency, body composition, and mental health were little studied (20%, 18% and 5% of RCTs, respectively). Our literature review revealed that much research in BS is wasted because of replication of RCTs on subjects for which there is already body of evidence, with small populations and follow-up times mostly below 2 years. Yet several research questions remain unaddressed, and there are few long-term trials. Future studies should take into account the experience of the past 70 years of research in this field.

Ventral Hernia Repair and Obesity: Results from a Nationwide Register Study in France According to the Timeframes of Hernia Repair and Bariatric Surgery.

PURPOSE: Several strategies are suggested for ventral hernia repair (VHR) in bariatric candidates, in terms of timing and technique. The aim was to describe practices in VHR in bariatric patients on a nationwide scale in France. MATERIALS AND METHODS: We used the prospective national hospital discharge summaries database system to conduct a retrospective cohort study. We included patients operated once for sleeve or bypass, between 2007 and 2018, and who had VHR concomitant with bariatric surgery (BS) or within 2 years before or after. RESULTS: Among 11,680 eligible patients, 2039 underwent VHR in the 2 years before BS, 3388 had concomitant BS and VHR, and 6260 patients had VHR within 2 years after BS. Patients who underwent a concomitant surgery presented a higher suture repair rate (86.1% versus 37.1% and 44.0%, P < 0.001). Overall recurrence of VH at 10 years was 23.3% and was higher for patients who underwent VHR first (36.2%) than patients who underwent BS first (24.5%) and the concomitant group (18.6%), P < 0.001. Major complication rate was 11.1%, 7.8%, and 16.9% (P < 0.001) for VHR-first, concomitant, and BS-first groups, respectively. Mesh infection was found in 0.6% (13/2039) of patients in the VHR-first group, in 0.6% (20/3388) in the concomitant group, and in 1.1% (68/6260) in the BS-first group (P < 0.001). CONCLUSION: About one-quarter of bariatric patients undergoing VHR will be reoperated for an anterior hernia. VHR before BS entailed a higher risk of reoperation for recurrence and should be avoided. A concomitant repair entailed the lowest rate of recurrence.

Half of Postoperative Deaths After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Could be Preventable: A French Root Cause Analysis on 5562 Patients.

OBJECTIVE: To perform a retrospective root-cause analysis of postoperative death after CRS and HIPEC procedures. BACKGROUND: The combination of CRS and HIPEC is an effective therapeutic strategy to treat peritoneal surface malignancies, however it is associated with significant postoperative mortality. METHODS: All patients treated with a combination of CRS and HIPEC between January 2009 and December 2018 in 22 French centers and died in the hospital, were retrospectively analyzed. Perioperative data of the 101 patients were collected by a local senior surgeon with a sole junior surgeon. Three independent experts investigated the typical root cause of death and provided conclusions on whether postoperative death was preventable (PREV group) or not (NON-PREV group). A typical root cause of preventable postoperative death was classified on a cause-and-effect diagram. RESULTS: Of the 5562 CRS+HIPEC procedures performed, 101 in-hospital deaths (1.8%) were identified, of which a total of 18 patients of 70 years old and above and 20 patients with ASA score of 3. Etiology of peritoneal disease was mainly colorectal. A total of 54 patients (53%) were classified in the PREV group and 47 patients (47%) in the NON-PREV group. The results of the study show that in the PREV group, WHO performance status 1-2 was more frequent and the Median Peritoneal Cancer Index was higher compared with those of the NON-PREV group. The cause of death in the PREV group was classified as: (i) preoperatively for debatable indication (59%), (ii) intraoperatively (30%) and (iii) postoperatively in 17 patients (31%). A multifactorial cause of death was found in 11 patients (20%). CONCLUSION: More than half of the postoperative deaths after combined CRS and HIPEC may be preventable, mainly by following guidelines regarding preoperative selection of the patients and adequate intraoperative decisions.

Spin occurs in bariatric surgery randomized controlled trials with a statistically nonsignificant primary outcome: A systematic review.

OBJECTIVES: To systematically identify the strategy and frequency of spin in reports of bariatric surgery randomized controlled trials (RCTs) with statistically nonsignificant primary endpoint. STUDY DESIGN AND SETTING: The use of specific reporting strategies to highlight the beneficial effect of an experimental treatment can affect the reader interpretation of trial results, particularly when the primary endpoint is not statistically significant. A literature search was performed to identify RCTs publications assessing the impact of bariatric surgery on obesity-related comorbidities published over the past 10 years (from January 2020 till December 2020) in MEDLINE and EMBASE. RCTs publications with statistically non-significant primary outcomes were included. RESULTS: Of 46 576 reports screened for title and abstract inclusion, 29 RCT reports met the inclusion criteria for spin analysis. In total, 16 abstracts (55%) and 18 main texts (62%) were classified as having a spin. In abstract results and conclusion sections, the spin was identified in 69% of reports. In main text results, discussion, and conclusion sections, the spin was recognized in 37%, 72%, and 76% of reports respectively. The spin consisted mainly of focusing on within-group improvements and the interpretation of statistically nonsignificant results as showing treatment equivalence. CONCLUSION: Spin occurred in a high proportion of bariatric surgery RCTs with a statistically nonsignificant primary endpoint.

The male external urethral sphincter is autonomically innervated.

INTRODUCTION: The aim of the present study was to describe autonomic urethral sphincter (US) innervation using specific muscular and neuronal antibody markers and 3D reconstruction. MATERIAL AND METHODS: We performed en-bloc removal of the entire pelvis of three male human fetuses between 18 and 40 weeks. Serial whole mount sections (5 µm intervals) were stained and investigated. The sections were stained with Masson's trichrome and Eosin Hematoxylin, and immunostained with: anti-SMA antibody for smooth muscle; anti-S100 antibody for all nerves; and anti-PMP22 antibody, anti-TH antibody, anti-CGRP antibody, anti-NOS antibody for somatic, adrenergic, sensory and nitrergic nerve fibers, respectively. The slides were digitized for 3D reconstruction to improve topographical understanding. An animated reconstruction of the autonomic innervation of the US was generated. RESULTS: The external and internal US are innervated by autonomic nerves of the inferior hypogastric plexus (IHP). These nerves are sympathetic (positive anti-TH antibody), sensory (positive anti-CGRP antibody), and nitrergic (positive anti-NOS antibody). Some autonomic fibers run within the neurovascular bundles, posterolaterally. Others run from the IHP to the posteromedial aspect of the prostate apex, above an through the rectourethral muscle. The external US is also innervated by somatic nerves (positive anti-PMP22 antibody) arising from the pudendal nerve, joining the midline but remaining below the rectourethral. CONCLUSIONS: This study provides anatomical evidence of an autonomic component in the innervation of the external US that travels in the neurovascular bundle. During radical prostatectomy, the rectourethral muscle and the neurovascular bundles are to be preserved, particularly during apical dissection.

Malignancy in bariatric surgery patients: a French multisite cohort.

BACKGROUND: Bariatric surgery is associated with decreased cancer-related mortality. An indefinite proportion of patients that undergo bariatric surgery have a history of malignancy or will develop cancer. In these patients, weight loss and oncologic evolution needed to be assessed. The aim of this study was to report the results of patients diagnosed with malignancy before and after bariatric surgery in a French multisite cohort. METHODS: We conducted a retrospective cohort study of all patients who underwent bariatric surgery in six university centers. Patients were divided in two groups: patients with a preoperative history of malignancy and patients diagnosed with malignancy during the follow-up. Both groups were compared with control groups of patients that underwent surgery during the same period. RESULTS: From 2008 to 2018, 8927 patients underwent bariatric surgery. In patients with a history of malignancy (n = 90), breast and gynecologic cancers were predominant (37.8%). Median interval between malignancy and surgery was 60 (38-118) months. After a follow-up of 24 (4-52) months, 4 patients presented with cancer recurrence. Comparative analysis demonstrated equivalent weight loss one year after surgery. In patients with postoperative malignancy (n = 32), breast and gynecologic cancers were also predominant (40.6%). Median interval between surgery and malignancy was 22 (6-109) months. In the comparative analysis, weight loss was similar at 2 years. CONCLUSIONS: History of malignancy should not be considered as an absolute contraindication for bariatric surgery. Gynecological cancer screening should be reinforced before and after surgery. The development of malignancy postoperatively does not seem to affect mid-term bariatric outcomes.

What are the Specifics of Abdominal Wall Surgery in Cirrhotic Patients.

The risk of developing an abdominal wall hernia is high in the cirrhotic patient, due to the association of ascites, hypoalbuminemia and amyotrophy in connection with undernutrition frequently associated with cirrhosis. Thus, almost 20% of cirrhotic patients develop an umbilical hernia. Parietal surgery is more at risk in cirrhotic patients and its indications must be discussed on a case-by-case basis. The objective of this work was to review the entire literature on wall surgery in order to best define the surgical indications and the specifics of their management. The bibliographic research was done on Pubmed over the period from January 1995 to December 2019, using French and English as publication languages. The keywords retained were "hernia" [Mesh] and "liver cirrhosis" [Mesh]. In an elective situation, preoperative ascites control is recommended. A parietal prosthesis can be used, even in the case of uninfected ascites, preferably in the retromuscular position. Laparoscopy should be used with caution, due to the bleeding risk. No recommendation can be made on the use of prophylactic intra-abdominal drainage. The literature data do not allow the trans-jugular route portosystemic shunt recommendation, nor the use of a peritoneal-vesical pump to decrease the volume of ascites before parietal surgery in cirrhotic patients.

Recurrence after elective incisional hernia repair is more frequent than you think: An international prospective cohort from the French Society of Surgery.

BACKGROUND: The French Society of Surgery has endorsed a cohort aiming to prospectively assess the frequency of recurrence after incisional hernia repair and to identify the risk factors. METHODS: Consecutive patients undergoing incisional hernia repair in the participating centers were included in the prospective French Society of Surgery cohort over a 6-month period. Patients were followed up with a computed tomography scan at 1 y and a clinical assessment by the surgeon at 2 years. RESULTS: A total of 1,075 patients undergoing incisional hernia repair were included in 61 participating centers. The median follow-up was 24.0 months (interquartile range: 14.0-25.3). The follow-up rates were 83.0% and 68.5% at 1 and 2 years, respectively. The recurrence rates were 18.1% at 1 year and 27.7% at 2 years. Recurrence risk factors at 2 years were a history of hernia (odds ratio = 1.57, 95% confidence interval = 1.05-2.35, P = .028), a lateral hernia (odds ratio = 1.84, 95% confidence interval = 1.19-2.86, P = .007), a concomitant digestive operation (odds ratio = 1.97, 95% confidence interval = 1.20-3.22, P = .007), and the occurrence of early surgical site complications (odds ratio = 1,90, 95% confidence interval = 1.06-3.38, P = .030). The use of surgical mesh was strongly associated with a lower risk of recurrence at 2 years (P < .001). CONCLUSION: After incisional hernia repair, the 2-year recurrence rate is as high as 27.7%. History of hernia, lateral hernia, concomitant digestive operation, the onset of surgical site complications, and the absence of mesh are strong risk factors for recurrence.

Daily medical education for confined students during coronavirus disease 2019 pandemic: A simple videoconference solution.

The outbreak of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 infection has recently spread globally and is now a pandemic. As a result, university hospitals have had to take unprecedented measures of containment, including asking nonessential staff to stay at home. Medical students practicing in the surgical departments find themselves idle, as nonurgent surgical activity has been canceled, until further notice. Likewise, universities are closed and medical training for students is likely to suffer if teachers do not implement urgent measures to provide continuing education. Thus, we sought to set up a daily medical education procedure for surgical students confined to their homes. We report a simple and free teaching method intended to compensate for the disappearance of daily lessons performed in the surgery department using the Google Hangouts application. This video conference method can be applied to clinical as well as anatomy lessons.

Mesh Repair in Crohn's Disease: A Case-Matched Multicenter Study in 234 Patients.

BACKGROUND: There are no specific guidelines for ventral hernia management in Crohn's disease (CD) patients. We aimed to assess the risk of septic morbidity after mesh repair in CD. METHODS: This was a retrospective multicentre study comparing CD and non-CD patients undergoing mesh repair for ventral hernia (primary or incisional hernia). Controls were matched 1:1 for the presence of a stoma, history of surgical sepsis, hernia size and Ventral Hernia Working Group (VHWG) score. All demographic, pre-, intra- and postoperative data were retrieved, including long-term data. RESULTS: We included 234 patients, with 114 CD patients. Both groups had comparable VHWG scores (p = 0.12), hernia sizes (p = 0.11), ASA scores ≥ 3 (p = 0.70), body mass index values (p = 0.14), presence of stoma (CD 21.9% vs. controls 15%, p = 0.16), history of sepsis (14% vs. 6.7%, p = 0.23), rates of malnutrition (4.4% vs. 1.7%, p = 0.46), rates of incisional hernia (93% vs. 95%, p = 0.68) and concomitant procedures (18.4% vs. 11.7%, p = 0.12). CD patients carried a higher risk of postoperative septic morbidity (18.4% vs. 5%, p = 0.001), entero-prosthetic fistula (7% vs. 0, p < 0.01) and mesh withdrawals (5.3% vs. 0, p = 0.011). Ventral hernia recurrence rates were similar (14% vs. 8.3%, p = 0.15). In the univariate analysis, the risk factors for septic morbidity were CD (p = 0.001), malnutrition (p = 0.004), use of biological mesh (p < 0.0001) and concomitant procedure (p = 0.004). The mesh position, the means used for mesh fixation as well as the presence of a stoma were not identified as risk factors. CONCLUSIONS: CD seems to be a risk factor for septic morbidity after mesh repair.

Right Colectomy with Absorbable Mesh Repair as a Salvage Solution for the Management of Giant Incisional Hernia with Loss of Domain: Results of a Bicentric Study.

BACKGROUND: Incisional hernia (IH) may occur in 20% of patients after laparotomy. The hernia sac volume may be of significance, with reintegration of visceral contents potentially leading to repair failure or abdominal compartment syndrome. The present study aimed to evaluate a two-step surgical strategy comprising right colectomy for hernia reduction with synchronous absorbable mesh repair followed by definitive non-absorbable mesh repair in recurrence. METHODS: Patients operated between 2012 and 2017 at two university centers were retrospectively included. Volumetric evaluation of the IH was performed by CT imaging. RESULTS: Eleven patients were included. The mean BMI was 43 kg/m2 (23-52 kg/m2). Progressive preoperative pneumoperitoneum was performed in 82% of patients, with complications in 22%. The mean volumetric ratio of the volume of the hernia to the volume of the abdominal cavity was 70% (48-100%). The first parietal repair was performed using an synthetic absorbable mesh (36%), a biologic mesh (27%), or a slowly absorbable mesh (36%). No patients died as a result of the procedure. Seven (64%) patients developed grade III-IV complications, including one case of an anastomotic fistula. Recurrence occurred in eight (73%) patients after the first repair. Of these, four (50%) patients were reoperated using a non-absorbable mesh, leading to solid repair in 75% of cases. After 27 ± 18 months of follow-up, the residual IH rate was 46%. CONCLUSIONS: Right colectomy for volume reduction in IH with loss of domain potentially represents an appropriate salvage option, supporting bowel reintegration and temporary hernia repair with absorbable material.

Ventral hernia surgery in morbidly obese patients, immediate or after bariatric surgery preparation: Results of a case-matched study.

BACKGROUND: Obesity is a risk factor for the development of ventral hernia and increases the risk of recurrence and surgical site infection after hernia repair (HR). OBJECTIVES: We tested the hypothesis that bariatric surgery (BS) before HR would decrease these risks in patients with morbid obesity. SETTING: University hospital, France. METHODS: We retrospectively compared 2 groups of patients with morbid obesity in a case-matched study; 1 underwent immediate HR surgery (control), and the other initially underwent BS and then HR after weight loss (case). Patients were individually matched at a 2:1 ratio according to defect size (<7 or ≥7 cm), obesity grade (<40 or ≥40 kg/m²), American Society of Anesthesiologists score, sex, smoker status, and presence of chronic obstructive pulmonary disease. RESULTS: From 2000 to 2017, 41 patients underwent BS, in association with herniorrhaphy in 14 cases (34%). Initial body mass index was higher in the BS group (46.7 ± 6.4 versus 42.4 ± 7.2, P < .0001) but had decreased by the time of HR (34.1 ± 6.5 versus 42.3 ± 7.2, P < .0001). Prosthetic HR was performed after 21.5 months (range, 7-87); however, 7 patients did not receive HR at this time due to insufficient weight loss. Postoperative morbidity was similar in the 2 groups. Hospital stay was shorter in the BS group (6.2 ± 2.6 versus 10.7 ± 9.3 d, P = .002). After a median follow-up of 4.6 ± 4.1 years, the recurrence rate was lower in the BS group (2/30, 6.7%) than in the control group (12/50, 24%; P = .048). CONCLUSION: For morbidly obese patients with ventral hernia, BS before HR surgery can decrease recurrence without increasing morbidity.

[Colorectal cancer surgery in the elderly]. / Chirurgie du cancer colorectal chez la personne âgée.

Colorectal cancer risk factors increase with age, comorbidities, delayed diagnosis, obstruction, emergency and frailty. Surgery is the standard treatment as the survival rate for this pathology is the same as in young patients. It would appear that there is an excess morbidity and mortality of colorectal cancer surgery in the elderly. Early rehabilitation is to be favoured during the postoperative period.

Postoperative morbidity and mortality for malignant colon obstruction: the American College of Surgeon calculator reliability.

BACKGROUND: The American College of surgical risk calculator (SRC) score has never been validated specifically for surgery in emergency. The objective was to evaluate the reliability of this calculator in patients with malignant colon obstruction. MATERIALS AND METHODS: We retrospectively have analyzed the morbidity and mortality observed in operated patients. Risk factors for postoperative morbidity and mortality were analyzed by logistic regression model. We have compared the morbidity and mortality estimated by the SRC score with that observed using the Brier Score (BS). A BS of 0 indicated perfect prediction, whereas a BS of 1 indicated the poorest prediction. RESULTS: Sixty-nine patients aged 75 y (41-93) have been operated on emergency from November 2001 to August 2015. The tumor was localized in the sigmoid in 33 cases (48%), in the splenic flexure in nine cases (13%), and in the right colon in 17 cases (25%). The surgical procedures were as follows: right colectomy with anastomosis (29%), diverting proximal iliac colostomy (23%), and subtotal colectomy with anastomosis (19%). The SRC score indicated a good predictivity for mortality (9.8% predicted versus 8.7% observed, BS = 0.058), for morbidity (33.4% versus 40.6%, BS = 0.209), and for serious morbidity (25.5% versus 17.4%, BS = 0.131). In multivariate analysis, SRC was an independent risk factor for mortality (P = 0.030 odds ratio [OR] = 1.07 [1.01-1.15]) and morbidity (P = 0.001 OR = 1.16 [1.08-1.27]). CONCLUSIONS: SRC score is a reliable tool for assessing the morbidity and mortality of obstructive colon cancer and could help with adapting the surgical gesture to the risks predicted.
