Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for pseudomyxoma peritonei of appendicular and extra-appendicular origin.

BACKGROUND: The prognostic value of the primary neoplasm responsible for pseudomyxoma peritonei (PMP) remains poorly studied. The aim of this study was to determine the prognosis for patients with extra-appendicular PMP (EA-PMP) treated optimally with complete cytoreductive surgery (CCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: All patients treated for PMP with CCRS and HIPEC between 1994 and 2016 were selected retrospectively from a French multicentre database. Patients with EA-PMP had pathologically confirmed non-neoplastic appendices and were matched in a 1 : 4 ratio with patients treated for appendicular PMP (A-PMP), based on a propensity score. RESULTS: Some 726 patients were identified, of which 61 (EA-PMP group) were matched with 244 patients (A-PMP group). The origins of primary tumours in the EA-PMP group included the ovary (45 patients), colon (4), urachus (4), small bowel (1), pancreas (1) and unknown (6). The median peritoneal carcinomatosis index was comparable in EA-PMP and A-PMP groups (15·5 versus 18 respectively; P = 0·315). In-hospital mortality (3 versus 2·9 per cent; P = 1·000) and major morbidity 26 versus 25·0 per cent; P = 0·869) were also similar between the two groups. Median follow-up was 66·9 months. The 5-year overall survival rate was 87·8 (95 per cent c.i. 83·2 to 92·5) per cent in the A-PMP group and 87 (77 to 96) per cent in the EA-PMP group. The 5-year disease-free survival rate was 66·0 (58·7 to 73·4) per cent and 70 (53 to 83) per cent respectively. CONCLUSION: Overall and disease-free survival following treatment with CCRS and HIPEC is similar in patients with pseudomyxoma peritonei of appendicular or extra-appendicular origin.

Influence of preoperative life satisfaction on recovery and outcomes after colorectal cancer surgery - a prospective pilot study.

BACKGROUND: Colorectal surgery has an important impact on a patient's quality of life, and postoperative rehabilitation shows large variations. To enhance the understanding of recovery after colorectal cancer, health-related quality of life has become a standard outcome measurement for clinical care and research. Therefore, we aimed to correlate the influence of preoperative global life satisfaction on subjective feelings of well-being with clinical outcomes after colorectal surgery. METHODS: In this pilot study of consecutive colorectal surgery patients, various dimensions of feelings of preoperative life satisfaction were assessed using a self-rated scale, which was validated in French. Both objective (length of stay and complications) and subjective (pain, subjective well-being and quality of sleep) indicators of recovery were evaluated daily during each patient's hospital stay. RESULTS: A total of 112 patients were included. The results showed a negative relationship between life satisfaction and postoperative complications and a significant negative correlation with the length of stay. Moreover, a significant positive correlation between life satisfaction and the combined subjective indicators of recovery was observed. CONCLUSION: We have shown the importance of positive preoperative mental states and global life satisfaction as characteristics that are associated with an improved recovery after colorectal surgery. Therefore, patients with a good level of life satisfaction may be better able to face the consequences of colorectal surgery, which is a relevant parameter in supportive cancer care.

Comparative study between biologic porcine dermal meshes: risk factors of postoperative morbidity and recurrence.

OBJECTIVE: Different types of biologic mesh have been introduced as an alternative to synthetic mesh for use in repairing contaminated ventral hernias because of their biocompatible nature. The aim of this study was to compare the clinical outcomes of patients who underwent complex ventral hernia repairs with either non cross-linked or cross-linked porcine dermal meshes. METHOD: This was retrospective analysis from a prospectively maintained database from January 2010 to May 2013. Patients undergoing open incisional hernia repair with a biologic mesh in the presence of a clean-contaminated, contaminated or dirty wound were reviewed. RESULTS: There were 39 patients who underwent single-staged abdominal wall reconstruction for a contaminated ventral hernia with a biologic mesh. In 15 cases, non cross-linked mesh was used (Strattice, n=8; Protexa, n=1; XenMatrix, n=6); a cross-linked mesh was used in the remaining 24 cases (Permacol n=21; CollaMend n=3). The median follow-up was 11.9 ± 10.6 months. The overall morbidity was 71.8% (n=28), with 15.4% (n=6) for grade I, 23.1% (n=9) for grade II, 23.1% (n=9) for grade III (n=3 grade IIIA, n=6 grade IIIB), 7.7% (n=3) for grade IV and 2.6% (n=1) for grade V. In the cross-linked group, there were six complications directly linked to the biologic mesh, compared with three in the non-cross-linked group. Overall wound morbidity was 41.0% (n=16). There were 13 hernia recurrences (33.3%), and recurrence rate was not significantly different for both groups. CONCLUSION: Despite the high rate of wound morbidity associated with the single-staged reconstruction of contaminated fields, it can be safely performed with biologic mesh reinforcement. Recurrence rate was not significantly different between cross-linked and non cross-linked porcine meshes.

KRAS and BRAF mutations are prognostic biomarkers in patients undergoing lung metastasectomy of colorectal cancer.

BACKGROUND: We evaluated KRAS (mKRAS (mutant KRAS)) and BRAF (mBRAF (mutant BRAF)) mutations to determine their prognostic potential in assessing patients with colorectal cancer (CRC) for lung metastasectomy. METHODS: Data were reviewed from 180 patients with a diagnosis of CRC who underwent a lung metastasectomy between January 1998 and December 2011. RESULTS: Molecular analysis revealed mKRAS in 93 patients (51.7%), mBRAF in 19 patients (10.6%). In univariate analyses, overall survival (OS) was influenced by thoracic nodal status (median OS: 98 months for pN-, 27 months for pN+, P<0.0001), multiple thoracic metastases (75 months vs 101 months, P=0.008) or a history of liver metastases (94 months vs 101 months, P=0.04). mBRAF had a significantly worse OS than mKRAS and wild type (WT) (P<0.0001). The 5-year OS was 0% for mBRAF, 44% for mKRAS and 100% for WT, with corresponding median OS of 15, 55 and 98 months, respectively (P<0.0001). In multivariate analysis, WT BRAF (HR: 0.005 (95% CI: 0.001-0.02), P<0.0001) and WT KRAS (HR: 0.04 (95% CI: 0.02-0.1), P<0.0001) had a significant impact on OS. CONCLUSIONS: mKRAS and mBRAF seem to be prognostic factors in patients with CRC who undergo lung metastasectomy. Further studies are necessary.

Intermediate cervical plexus block for cervical esophagus diverticulectomy.

We report the case of a 97 year old woman suffering from a voluminous diverticle of the cervical esophagus with important comorbidities and a very poor quality of life. A diverticulectomy under general anesthesia implied a high level of risk. Regional anesthesia was chosen, i.e. an intermediate cervical plexus block, with mild sedation allowing to maintain contact with the patient. The procedure was carried out without complications and the patient's and surgical staff satisfaction were optimal.

Parastomal hernia repair according to Modified Stapled Mesh Stoma Reinforcement Technique (mSMART): which are the results ?

INTRODUCTION: Parastomal hernia repair is a real surgical challenge because of the high rate of recurrence. The Stapled Mesh Stoma Reinforcement Technique (SMART) is a keyhole-like technique in which the mesh is stapled to the fascia using a circular mechanical stapler. METHODS: A prospective study from January 2021 to February 2023 was conducted including all patients operated with the SMART technique. Primary endpoint was the recurrence rate during the follow-up. Secondary endpoints were reoperation, Surgical site Occurrence (SSO) and deep (mesh) surgical site infection (SSI) within 30 days postoperatively. RESULTS: Sixteen patients operated on SMART procedures were included. The mean follow-up was 11.3 ± 9.2 months. The SSO rate was 18.7% (n = 3). A seroma was drained radiologically (IIIa), one haematoma was evacuated surgically (IIIb) and one patient presented a postoperative lesion of a ureter after a parastomal Bricker's hernia repair. In addition, there was one death due to multiple organ failure (V). There was no SSI. The recurrence rate was 57.1% during the follow-up. CONCLUSION: This study shows disappointing results for this SMART technique, with a high recurrence rate.

How I do it: using a hammock mesh in the reconstruction of inguinal ligament during a wide en-bloc resection of a groin mesenchymal tumor.

PURPOSE: In case of soft tissue sarcomas (STS), an en-bloc resection with safe margins is recommended. To ensure safe removal without tumor rupture, STS of the groin area, retroperitoneal or pelvic mesenchymal tumors may require incision or resection of the inguinal ligament. Solid reconstruction is mandatory to prevent early and late postoperative femoral hernias. We present here a new technique of inguinal ligament reconstruction. METHODS: Between September 2020 and September 2022, patients undergoing incision and/or resection of inguinal ligaments during a wide en-bloc resection of STS of the groin area in the Department of General Surgery in Strasbourg were included. All patients had an inguinal ligament reconstruction with biosynthetic slowly resorbable mesh shaped as a hammock, pre- or intraperitoneally, associated or not with loco-regional pedicled muscular flaps. RESULTS: A total of 7 hammock mesh reconstructions were performed. One or several flaps were necessary in 57% of cases (4 patients): either for inguinal ligament reconstruction only (n = 1), for recovering of femoral vessels (n = 1), and for both ligament reconstruction and defect covering (n = 2). The major morbidity rate was 14.3% (n = 1), related to a thigh surgical site infection due to sartorius flap infarction. After a median follow-up of 17.8 months (range 7-31), there was neither early nor late occurrence of post-operative femoral hernia. CONCLUSIONS: This is a new surgical tool for inguinal ligament reconstruction with the implementation of a biosynthetic slowly resorbable mesh shaped as a hammock, which should be compared to other techniques.

Do surgical drains reduce surgical site occurrence and infection after incisional hernia repair with sublay mesh? A non-randomised pilot study.

INTRODUCTION: Surgical site occurrence (SSO) and surgical site infection (SSI) are common concerns with incisional hernia repair. Intraoperative drain placement is a common practice aiming to reduce SSO and SSI rates. However, literature on the matter is very poor. The aim of this study is to investigate the role of subcutaneous and periprosthetic drain placement on postoperative outcomes and SSO and SSI rates with incisional hernia repair. METHODS: A non-randomised pilot study was performed between January 2018 and December 2020 and included patients with elective midline or lateral incisional hernia repair with sublay mesh placement. Patients were prospectively included, followed for 1 month and divided into three groups: group 1 without drainage, group 2 with subcutaneous drainage, and group 3 with subcutaneous and periprosthetic drains. Drains were placed at surgeon's discretion. All patients were included in the enhanced recovery program. RESULTS: One hundred and four patients were included. Twenty-four patients (23.1%) did not have drains (group 1), 60 patients (57.7%) had a subcutaneous drain (group 2) and 20 patients (19.2%) had both a subcutaneous and a periprosthetic drains (group 3). SSO rates were significantly different between the 3 groups: 20.8% in group 1, 20.7% in group 2 and 50% in group 3 (p = 0.03). There was no significant difference in deep and superficial SSI rates between the 3 groups. Subgroup analysis revealed that adding a drain in direct contact with the mesh significantly increased SSO rate but did not influence SSI rate. Length of stay was also significantly increased by the presence of a drain, 3.1 ± 1.9 days for group 1; 5.9 ± 4.8 for group 2 and 5.9 ± 2.5 days for group 3 (p < 0.005). CONCLUSION: Drain placement in direct contact with the mesh might increase SSO rate. More studies are necessary to evaluate the actual benefits of drainage after incisional hernia repair.

Cost-effectiveness analysis of resorbable biosynthetic mesh in contaminated ventral hernia repair.

BACKGROUND: The aim of this study was to compare, in terms of cost and serious complications, the use of biosynthetic resorbable parietal mesh with biologic mesh in patients undergoing contaminated ventral hernia repair (modified Ventral Hernia Working Group grade 3). Poly-4-hydroxy-butyrate (P4HB) biosynthetic mesh has rarely been the subject of comparative studies in the context of contamination. Data are required to confirm the effects of a transition from biological mesh to biosynthetic resorbable mesh. PATIENTS AND METHODS: A cost-effectiveness analysis was conducted. It was based on a decision analysis model built with clinical and economic data issued from a before-after study that included 94 patients hospitalized for ventral hernia repair at the University Hospital of Strasbourg (France) from June 2011 to February 2018. The effectiveness endpoint was the number of patients presenting with a serious specific complication or a general complication at 6 months. Data for surgical hospitalization stays, home hospitalizations and ambulatory care costs were included. RESULTS: We found fewer serious complications with biosynthetic mesh: 21% versus 33% with biologic mesh. A cost savings of US $5146 was determined. Deterministic sensitivity analyses and a probabilistic analysis confirmed our findings and the robustness of the model. CONCLUSION: P4HB biosynthetic resorbable mesh appeared to be the most effective and the least costly option. Additional data will be needed to confirm the superiority of biosynthetic mesh in terms of the recurrence risk reduction over a longer period.

Why and how to implement an electronic resident's surgical logbook to improve operating-room training? First 5-year feedback from a French center.

INTRODUCTION: The evaluation of general surgery residents' operating room (OR)-training and technical skills progression may be difficult in the absence of a standardized evaluation tool. The aim of this study was to evaluate the impact of the implementation of an electronic "surgical logbook" for general surgery residents. METHODS: A prospective single center study was conducted between May 2015 and October 2020. An electronic logbook was filled by all residents immediately after each surgical procedure and data were prospectively collected and analyzed. RESULTS: Fifty-five students (34 men/21 women) reported their participation to 6917 surgical procedures, which corresponded to 55.5% of all procedures performed in our department. Residents performed the entire procedure as the operating surgeon in 28.5% of cases (n=1963), parts of the procedure as operating surgeon in 32.5% of cases (n=2230) and as operating-assistant in 38.5% (n=2672). Residents were more likely an operating surgeon for the entire procedure when they were assisted by a fellow or a practicing physician than an associate professor or a clinical professor (P<0.001). There was no significant difference in the major morbidity rate between different resident's contribution to the procedure (P=0.14). CONCLUSION: We present here a simple, useful and cost efficient tool which offers easy data collection and reporting that could help improve OR-training, OR-supervision and certification at a local or national level.

Slowly absorbable mesh in contaminated incisional hernia repair: results of a French multicenter study.

PURPOSE: To analyze the postoperative morbidity and 1-year recurrence rate of incisional hernia repair using a biosynthetic long-term absorbable mesh in patients at higher risk of surgical infection in a contaminated surgical field. METHODS: All patients undergoing incisional hernia repair in a contaminated surgical field with the use of a biosynthetic long-term absorbable mesh (Phasix®) between May 2016 and September 2018 at six participating university centers were included in this retrospective cohort and were followed-up until September 2019. Regarding the risk of surgical infection, patients were classified according to the modified Ventral Hernia Working Group classification. Preoperative, operative and postoperative data were collected. All patients' surgical site infections (SSIs) and occurrences (SSOs) and recurrence rates were the endpoints of the study. RESULTS: Two hundred and fifteen patients were included: 170 with mVHWG grade 3 (79%) and 45 with mVHWG grade 2 (21%). The SSI and SSO rates at 12 months were 22.3% and 39.5%, respectively. According to the Dindo-Clavien classification, 43 patients (20.0%) had at least one minor complication, and 57 patients (26.5%) had at least one major complication. Among the 121 patients (56.3%) having at least 1 year of follow-up, the clinical recurrence rate was 12.4%. Multivariate analysis showed that a concomitant gastrointestinal procedure was an independent risk factor for surgical infection (OR = 2.61), and an emergency setting was an independent risk factor for major complications (OR = 11.9). CONCLUSION: The use of a biosynthetic absorbable mesh (Phasix®) is safe in a contaminated surgical field, with satisfying immediate postoperative and 1-year results. TRIAL REGISTRATION: The study is registered on Clinical Trial ID: NCT04132986.

Dialkylcarbamoyl chloride-coated versus alginate dressings after pilonidal sinus excision: a randomized clinical trial (SORKYSA study).

BACKGROUND: Disease of the pilonidal sinus is a common condition that affects mainly young adults. Options for management include excision of the sinus tracts, leaving the wound open to heal by secondary intention. The aim of this study was to compare wound healing with dialkylcarbamoyl chloride (DACC)-coated dressings versus alginate dressings. METHODS: This multicentre trial randomized consecutive patients undergoing surgery for pilonidal disease to postoperative wound care with either DACC-coated or alginate dressings. The primary outcome was the proportion of wounds healed after 75 days. Secondary outcomes were the local status of wounds during the healing process, the quality assessment of the dressings by the patient, and the time needed to return to usual activities. RESULTS: A total of 246 patients were included: 120 in the DACC-coated group and 126 in the alginate group. In per-protocol analysis, there were significantly more patients with completely healed wounds after 75 days in the DACC group than in the alginate group: 78 of 103 (75·7 per cent) versus 58 of 97 (60 per cent) respectively (odds ratio 2·55, 95 per cent c.i. 1·12 to 5·92; P = 0·023). During follow-up, wounds with alginate dressings had more fibrin than those with DACC-coated dressings, but the difference was not significant (P = 0·079). There was no difference between the two arms in patients' assessment of the dressings. CONCLUSION: The number of wounds completely healed at 75 days was significantly higher for DACC-coated compared with alginate dressings. However, the preplanned, clinically significant improvement in healing of 20 per cent was not reached. Registration number: NCT02011802 ( https://clinicaltrials.gov/).

ANTECEDENTES: El sinus pilonidal es una afección común que afecta principalmente a adultos jóvenes. Las opciones de tratamiento incluyen la escisión de los trayectos del sinus, dejando la herida abierta para cicatrizar por segunda intención. El objetivo de este estudio fue comparar la cicatrización de heridas con apósitos recubiertos con cloruro de diaquilcarbamoilo (dialkylcarbamoyl chloride, DACC) en comparación con apósitos de alginato. MÉTODOS: En este ensayo multicéntrico se asignó al azar a pacientes consecutivos sometidos a cirugía por sinus pilonidal a uno de los dos brazos: cuidado postoperatorio de heridas con apósitos recubiertos con DACC o con alginato. El criterio de valoración principal fue la proporción de heridas curadas después de 75 días. Los criterios de valoración secundarios fueron el estado local de las heridas durante el proceso de curación, la evaluación de la calidad de los apósitos por parte del paciente y el tiempo necesario para volver a la actividad profesional. RESULTADOS: Se incluyeron un total de 246 pacientes: 120 en el grupo de apósitos recubiertos de DACC y 126 en el grupo de alginato. En el análisis por protocolo, hubo significativamente más pacientes con heridas completamente curadas después de 75 días en el grupo DACC que en el grupo de alginato: 78 de 103 (75,7%) y 58 de 97 (59,7%) respectivamente (razón de oportunidades, odds ratio, OR = 2,55; (1,12; 5,92); P = 0,02)). Durante el seguimiento, las heridas recubiertas con apósitos de alginato tenían más fibrina que las recubiertos con DACC, pero la diferencia no fue significativa (P = 0,08). No hubo diferencias entre los dos brazos en la evaluación realizada por los pacientes de los apósitos. CONCLUSIÓN: El número de heridas completamente curadas a los 75 días fue significativamente mayor con los apósitos recubiertos con DACC en comparación con los apósitos de alginato. Sin embargo, no se alcanzó la mejoría clínicamente significativa preestablecida de una curación del 20%.

Strategy for the practice of digestive and oncological surgery during the Covid-19 epidemic.

The Covid-19 pandemic is changing the organization of healthcare and has a direct impact on digestive surgery. Healthcare priorities and circuits are being modified. Emergency surgery is still a priority. Functional surgery is to be deferred. Laparoscopic surgery must follow strict rules so as not to expose healthcare professionals (HCPs) to added risk. The question looms large in cancer surgery-go ahead or defer? There is probably an added risk due to the pandemic that must be balanced against the risk incurred by deferring surgery. For each type of cancer-colon, pancreas, oesogastric, hepatocellular carcinoma-morbidity and mortality rates are stated and compared with the oncological risk incurred by deferring surgery and/or the tumour doubling time. Strategies can be proposed based on this comparison. For colonic cancers T1-2, N0, it is advisable to defer surgery. For advanced colonic lesions, it seems judicious to undertake neoadjuvant chemotherapy and then wait. For rectal cancers T3-4 and/or N+, chemoradiotherapy is indicated, short radiotherapy must be discussed (followed by a waiting period) to reduce time of exposure in the hospital and to prevent infections. Most complex surgery with high morbidity and mortality-oesogastric, hepatic or pancreatic-is most often best deferred.

[The usefulness of scores in the diagnosis of appendicitis]. / De l'intérêt des scores en matière de diagnostic d'appendicite.

The diagnosis of acute appendicitis relies largely on clinical experience; the performance of complementary tests is oftentimes unnecessary. We have created a score based on clinical and laboratory findings which can reliably categorize three zones of diagnostic probability : probable, doubtful, or improbable. Only the intermediate category requires complementary imaging. Alvarado first developed a scoring system based on operative findings and this has been modified and improved by others. In our experience, the scoring system of François has been most useful. This score is based on simple clinical data and findings such as age, sex, duration of symptoms, leucocytosis, palpable mass on rectal exam, and urinary symptoms. We have validated this score in a cohort of 202 patients presenting with right lower quadrant abdominal pain and found a sensitivity of 94.7% and a negative predictive value of 97.4% for patients falling into the probable and improbable categories. Management of patients with either very high or very low scores can proceed more expeditiously and with less expense. Diagnostic imaging can be reserved for those patients with intermediate scores where the diagnosis is in doubt. We have established a clinical pathway in our emergency department based on this scoring system.

Occupational safety of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in an operating room without laminar airflow.

AIM OF THE STUDY: The safety of pressurized intraperitoneal aerosol chemotherapy (PIPAC) is often questioned when newly implemented in an operating room (OR); as it may increase the risk of exposure to cytotoxics for healthcare workers. There are no data on the risk of healthcare exposure in OR without laminar airflow. We aimed to ensure the safety of PIPAC for surgeons and their co-workers for newly implemented procedures in an OR without laminar airflow. PATIENTS AND METHODS: Twenty-six samples with cellulosic wipes from surgeons and co-workers' environmental items and 5 specific polytetrafluoroethylene air-filtered collections were randomly performed for the first 2 cisplatin/doxorubicin-based PIPAC procedures in Strasbourg University Hospital. PIPAC was performed according to previously described safety protocol but without a laminar airflow and with an additional plastic cover and smoke evacuation device. Sampling and analyzes were performed by 2 accredited independent certified organizations. RESULTS: All air measurements were negative for cisplatin and doxorubicin. Only one wipe sample out of 26 was positive for cisplatin (4%) on the outer surgeon's pair of gloves but dosages on the surgeon's inner pair and hands were negative. CONCLUSION: When performed in approved security conditions, even without laminar airflow, PIPAC might seem harmless for surgeons and their co-workers with very limited risk of exposure to cytotoxics.

Recurrence of pseudomyxoma peritonei after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Background: Pseudomyxoma peritonei (PMP) is a rare clinical condition characterized by mucinous ascites, typically related to appendiceal or ovarian tumours. Current standard treatment involves cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), but recurrences occur in 20-30 per cent of patients. The aim of this study was to define the timing and patterns of recurrence to provide a basis for modifying follow-up of these patients. Methods: This observational study examined a prospectively developed multicentre national database (RENAPE working group) to identify patients with recurrence after optimal CRS and HIPEC for PMP. Postoperative complications, long-term outcomes and potential prognostic factors were evaluated. Results: Of 1411 patients with proven PMP, 948 were identified who had undergone curative CRS and HIPEC. Among these patients, 229 first recurrences (24·2 per cent) were identified: 196 (20·7 per cent) occurred within the first 5 years (early recurrence) and 30 (3·2 per cent) occurred between 5 and 10 years. Three patients developed a first recurrence more than 10 years after the original treatment. The mean(s.d.) time to first recurrence was 2·36(2·21) years. Preoperative chemotherapy and high-grade pathology were significant factors for early recurrence. Overall survival for the entire group was 77·9 and 63·1 per cent at 5 and 10 years respectively. The principal site of recurrence was the peritoneum. Conclusion: Recurrence of PMP was rare after 5 years and exceptional after 10 years.

[Suspension diverticulopexy for Zenker's diverticulum]. / Traitement du diverticule de Zenker par diverticulopexie.

INTRODUCTION: Zenker's diverticulum is an unusual condition. Its treatment requires surgery but there is no consensus regarding the various operative techniques. Through an open cervical approach, the diverticulum can be either resected or suspended with or without a concurrent myotomy of the cricopharyngeus muscle. An innovative option is endoscopic trans-oral stapled esophago-diverticulostomy. PATIENTS: and method: We retrospectively reviewed a consecutive series of 36 patients operated on between 1988 and 2006. Median age was 77.5 years and M/F sex ratio was 1.4. Through an open neck approach, diverticulectomy without cricopharyngeal myotomy was performed in 7 patients, diverticulectomy with myotomy in 11, and diverticulopexy with myotomy in 18. RESULTS: Morbidity rate was 13.8%. One fistula and one recurrence occurred in both diverticulectomy groups with and without myotomy. There was no morbidity after suspension diverticulopexy which also allowed earlier oral feeding (1 vs. 6 days) and shortened hospitalization (6 vs. 13.5 days). CONCLUSION: Diverticulopexy with cricopharyngeus myotomy is an effective, reliable, and reproducible technique for the correction of Zenker's diverticula smaller than 5 cm. Diverticulectomy should be reserved for larger diverticula. Technical improvements of transoral stapled diverticulostomy are still required before it can be promoted as an alternative therapy.

[Peritoneal mesothelioma: treatment with cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy]. / Mésothéliome péritonéal: traitement par l'association chirurgie de cytoréduction et chimiothérapie hyperthermique intrapéritonéale.

UNLABELLED: Diffuse malignant peritoneal mesothelioma is a rare and lethal disease. Locoregional treatments combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) seem to improve prognosis. METHODS: Cytoreductive surgery and HIPEC was performed in 22 patients at the Centre Hospitalier-Lyon Sud between 1989 and 2006. A retrospective analysis of survival was carried out to assess clinical and histological prognostic factors. RESULTS: Nineteen patients with diffuse malignant peritoneal mesothelioma were included (16 epithelial, 3 biphasic and 3 multicystic forms). Sixteen patients presented stage 3 or 4 peritoneal mesothelioma according to the Gilly classification. Optimal cytoreductive surgery was performed for 11 patients (complete macroscopic resection or residual tumor nodules less than 2.5mm). No post-operative deaths occurred but 9 patients (47%) presented grade III or IV post-operative complications. The overall median survival was 36.9 months; completeness of cytoreduction was the only significant prognostic factor. CONCLUSION: Cytoreductive surgery combined with HIPEC may improve the length of survival for patients with diffuse malignant peritoneal mesothelioma; such patients should be treated in specialized centers.

Outcomes of hypnosis combined with local anesthesia during inguinal repair: a pilot study.

PURPOSE: To evaluate the usefulness and outcomes of hypnosis associated with local anesthesia during inguinal hernia repair procedure, notably on post-operative pain. METHODS: A prospective study included patients operated on inguinal hernia repair according to Lichtenstein technique from January 2013 to September 2014. The cohort was divided into three groups (group 1: local anesthesia; group 2: hypnosis and local anesthesia; and group 3: general anesthesia). A questionnaire was filled by each participant before and after surgery. Pre-operative apprehension, pain at hospital discharge, surgeon comfort during procedure, immediate satisfaction after hospital discharge, and satisfaction at 1 month after surgery were evaluated. RESULTS: A total of 103 patients were included in this study (group 1: n = 55; group 2: n = 35; and group 3: n = 13). Pre-operative apprehension and pain at hospital discharge's scores were significantly higher in the group 3 than in the groups 1 and 2 (p < 0.001). Pain at hospital discharge was significantly lower in the group 2 than in the group 1 (p = 0.03). Pre-operative apprehension, surgeon comfort during procedure, immediate satisfaction after hospital discharge, and satisfaction at 1 month after surgery were similar between groups 1 and 2. CONCLUSION: Hypnosis combined with local anesthesia is a feasible technique which allows extending inguinal hernia repair to a large population. There is no complication associated with its use.
