ABSTRACT
BACKGROUND: Intraoperative decision of the level of distal resection in rectal cancer is often imprecise, based exclusively on digital examination and pretherapeutic imaging. DESIGN: Prospective, single institution, nonrandomized trial ( ClinicalTrial.gov identification no. NCT01887509) to evaluate the contribution of probe-based confocal laser endomicroscopy (pCLE) to establish the optimal resection margin of rectal adenocarcinoma. The primary outcome was the concordance in the identification of lower tumor margins between pCLE and histopathology. For each patient, pCLE examination was performed on nonneoplastic and neoplastic aspects of the distal tumor margin, before and after neoadjuvant chemoradiation, or preceding surgery, if chemoradiation was not required. Biopsies were taken at the same locations. The intraclass correlation coefficient was determined. RESULTS: Twenty-one patients were enrolled. Thirteen patients completed the full study. Six patients completed imaging only before chemoradiation. Two patients retracted their consent after inclusion. A total of 134 videos and corresponding histopathology samplings were analyzed. The sensitivity and specificity of in vivo pCLE interpretation were 0.915 (95% confidence interval [CI] = 0.840-0.970) and 0.736 (95% CI = 0.657-0.821), respectively. The sensitivity and specificity of the blinded pCLE reinterpretation were 0.930 (95% CI = 0.858-0.980) and 0.688 (95% CI = 0.600-0.770), respectively. No deep layer tumor infiltration was encountered in the samplings with superficial healthy layers. The intraclass correlation coefficient for in vivo pCLE interpretation and blinded pCLE reinterpretation were 0.747 (95% CI = 0.257-0.993) and 0.766 (95% CI = 0.280-0.995), respectively. CONCLUSIONS: This supports the concordance between pCLE and histopathology in identifying the "tumor-free" limit of a rectal tumor preceding resection.

Short-course (less than 7 days) antibiotic treatments have been rarely assessed in the management of leptospirosis. We analyzed the charts of patients hospitalized with confirmed and probable leptospirosis in a teaching hospital between 1994 and 2012. Of 89 patients with confirmed or probable leptospirosis, 21 patients (11 confirmed, 10 probable - 14 uncomplicated and 7 severe forms) admitted between 2001 and 2012 received ceftriaxone (1-2 g daily) for less than 7 days. Apyrexia was obtained within 2 days of treatment in all patients and no relapse was observed. These data support the hypothesis that short-course treatments of 3-6 days with ceftriaxone (1-2 g per day) may be an option in the treatment of uncomplicated and severe forms of leptospirosis responding quickly to therapy. This hypothesis deserves being confirmed in further clinical studies.

OBJECTIVE: To verify the hypothesis that in most patients bowel segmental resection to treat endometriosis can be safely performed without creation of a stoma and to discuss the limitations of this statement. DESIGN: Retrospective study (Canadian Task Force classification III). SETTING: Tertiary referral center. PATIENTS: Forty-one women with sigmoid and rectal endometriotic lesions who underwent segmental resection. INTERVENTION: Segmental resection procedures performed between 2004 and 2011. Patient demographic, operative, and postoperative data were compared. MEASUREMENTS AND MAIN RESULTS: Sigmoid resection was performed in 6 patients (15%), and rectal anterior resection in 35 patients (high in 21 patients [51%], and low, i.e., <10 cm from the anal verge, in 14 [34%]). In 4 patients a temporary ileostomy was created. There was 1 anastomotic leak (2.4%), in a patient with an unprotected anastomosis, which was treated via laparoscopic surgery and creation of a temporary ileostomy. Other postoperative complications included hemoperitoneum, pelvic abscess, pelvic collection, and a ureteral vaginal fistula, in 1 patient each (all 2.4%). CONCLUSION: A protective stoma may be averted in low anastomosis if it is >5 cm from the anal verge and there are no adverse intraoperative events.

INTRODUCTION: Current recommendations urge us to operate quickly on femoral neck fractures to reduce the risk of comorbidity decompensation. In some cases, this leads us to operate when an underlying infection is present. In this study, we evaluated the infection rate of bipolar hemiarthroplasty after femoral neck fracture and attempted to relate it to preoperative C-reactive protein (CRP) levels. MATERIALS AND METHODS: The infection rate of bipolar hemiarthroplasty was evaluated in a dual-center, retrospective study of 260 patients over a 2-year period. During the first year, the preoperative CRP levels were not taken into account when scheduling the procedure. During the second year, if preoperative CRP levels were above 50 mg/L, the procedure was delayed to look for and treat any ongoing infections. RESULTS: The overall periprosthetic infection rate in this study was 4.85 % (range 4.8-4.9), with 33 % of patients passing within 1 year due to the infection. In the group where CRP was not taken into consideration, 59 of the 143 operated away patients (41 %) had their preoperative CRP levels measured. Twenty-nine of these patients had CRP > 50 mg/L when they were operated. Of the seven infections in the group, one patient had CRP > 50 mg/L, two had CRP < 50 mg/L, and four patients did not have preoperative CRP levels measured. In the group where CRP was taken into consideration, 104 of the 117 patients (89 %) had their preoperative CRP assessment. Thirty of these patients had CRP > 50 mg/L upon admission; their procedure was delayed to determine the etiology of this CRP elevation. No cause was found in 16 of these 30 patients, and they were operated despite having CRP > 50 mg/L. There were five infections in this group: four patients had CRP > 50 mg/L and were treated accordingly; one patient had preoperative CRP < 50 mg/L. In patients where the preoperative CRP levels were taken into account, the delay before surgery was twice as long as those where CRP levels were not considered. DISCUSSION: C-reactive protein (CRP) level alone is not a good preoperative predictive factor for periprosthetic joint infection, although 80 % of the patient with an infected bipolar hemiarthroplasty had CRP > 50 mg/L upon admission. The increased delay due to the CRP analysis is not without consequence for this cohort. Two previous studies have looked into the predictive ability of CRP levels, but these involved scheduled surgical procedures. CONCLUSION: This study could not validate the use of CRP levels, nor a 50 mg/L threshold, as predictive factors for a preexisting infection during bipolar hemiarthroplasty for femoral neck fracture. As a consequence, new infection screening tools must be developed and validated.

The objective of this retrospective study was to evaluate the feasibility of natural orifice specimen extraction (NOSE) techniques in 41 patients undergoing bowel resection for treatment of deep infiltrating endometriosis. In all patients laparoscopic treatment of rectovaginal endometriosis with bowel resection had been performed. In 32 patients the classic approach was adopted (group 1), and in 9 a NOSE technique was performed (group 2). Demographic, operative, and postoperative data were compared. Statistical analyses were performed using SPSS software, version 16.0. When needed, qualitative variables were compared using the χ(2) test or the Fisher exact test. Quantitative variables using the t-test were used. The threshold of statistical significance was set at p = .05. No statistically significant difference was observed between the 2 groups. Eight complications (19.5%) were observed, 2 minor (4.8%) and 6 major (14.6%). Of major complications, 2 were observed in the NOSE group (n = 2; 22.2%). It was concluded that the NOSE technique is a feasible approach in patients undergoing bowel resection for treatment of deep infiltrating endometriosis.

INTRODUCTION: Reducing the number of abdominal incisions in laparoscopic cholecystectomy introduces ergonomic challenges while establishing the critical view during dissection of the triangle of Calot (TC). This study investigates the use of a novel internal retracting device in performing cholecystectomy with a reduced number of ports. METHODS: A 3-port laparoscopic cholecystectomy was attempted by 4 surgeons unfamiliar with the novel device. Exposure of the TC was obtained using the internal retractor, which comprises 2 clips, linked by an adjustable thread. One clip is fixed on the gallbladder and the other is fixed to the peritoneum. The endpoint was to evaluate the efficacy and reliability of the device in establishing the critical view of safety. RESULTS: Thirteen patients with a mean body mass index of 25.29 kg/m(2) (standard deviation = 6.24; range = 17.6-36.7 kg/m(2)) were included in the study. The critical view was obtained in 10 of 13 patients. Application of the device was completed in a median time of 2.25 minutes without injury of the gallbladder or bile leak. Failure occurred in 3 patients, related to wrong manipulation of the device (2 patients), and correct placement of the device but inadequate exposure (1 patient). A conventional 4-port technique was used in these patients. Operators rated their experience with the device as an "easy-to-operate" device with a good safety profile and without any interference with the operative process. CONCLUSIONS: Throughout the minimization process specific to minimal access surgery, internal retractors will certainly allow for a reduction in the number of trocars used in laparoscopic procedures.

BACKGROUND: The aim of our study was to assess the detection of circulating DNA from the most common species of Mucorales for early diagnosis of mucormycosis in at-risk patients. METHODS: We retrospectively evaluated a combination of 3 quantitative polymerase chain reaction (qPCR) assays using hydrolysis probes targeting Mucor/Rhizopus, Lichtheimia (formerly Absidia), and Rhizomucor for circulating Mucorales detection. Serial serum samples from 10 patients diagnosed with proven mucormycosis (2-9 samples per patient) were analyzed. RESULTS: No cross-reactivity was detected in the 3 qPCR assays using 19 reference strains of opportunistic fungi, and the limit of detection ranged from 3.7 to 15 femtograms/10 µL, depending on the species. DNA from Mucorales was detected in the serum of 9 of 10 patients between 68 and 3 days before mucormycosis diagnosis was confirmed by histopathological examination and/or positive culture. All the qPCR results were concordant with culture and/or PCR-based identification of the causing agents in tissue (Lichtheimia species, Rhizomucor species, and Mucor/Rhizopus species in 4, 3, and 2 patients, respectively). Quantitative PCR was negative in only 1 patient with proven disseminated mucormycosis caused by Lichtheimia species. CONCLUSION: Our study suggests that using specific qPCR targeting several species of Mucorales according to local ecology to screen at-risk patients could be useful in a clinical setting. The cost and efficacy of this strategy should be evaluated. However, given the human and economic cost of mucormycosis and the need for rapid diagnosis to initiate prompt directed antifungal therapy, this strategy could be highly attractive.

STUDY OBJECTIVE: To describe a more conservative and less invasive surgical approach to laparoscopic colorectal segmental resection for treatment of endometriosis. DESIGN: Video of elective sigmoidectomy to treat colorectal endometriosis. SETTING: Tertiary referral center for laparoscopic gynecologic surgery at the University Hospitals of Strasbourg, France. PATIENT: A 29-year-old woman with dysmenorrhea, constipation, and cyclic diarrhea and two sigmoid endometriotic lesions evident at colonoscopy. INTERVENTION: The conservative surgical strategy, possible in cases of benign lesions such as endometriosis, consists of dividing the mesentery close to the digestive tract to preserve the vascular-lymphatic vessels and the surrounding sympathetic and parasympathetic nerves. The less invasive approach consists of natural orifice specimen extraction via the transanal route. MEASUREMENTS AND MAIN RESULTS: The postoperative course was favorable. The conservative technique enables preservation of the superior rectal vessels, which contribute to 80% of the vascularization of the rectum, to maintain the best vascularization, essential for intestinal anastomosis. Transanal specimen extraction maximizes the benefits of laparoscopy by sparing the abdominal wall from incision and its associated complications. CONCLUSION: A conservative surgical approach should be used in segmental bowel resection for treatment of endometriosis. Moreover, the segmental bowel resection can be safely performed with transanal specimen extraction, with great advantages for the patient.

STUDY OBJECTIVE: To show a new technique of laparoscopic intracorporeal anastomosis for transrectal bowel resection with transvaginal specimen extraction, a technique particularly suited for treatment of bowel endometriosis. DESIGN: Step-by-step explanation of the technique using videos and pictures (educative video). SETTING: Endometriosis may affect the bowel in 3% to 37% of all endometriosis cases. Bowel endometriosis affects young women, without any co-morbidities and in particular without any vascular disorders. In addition, affected patients often express a desire for childbearing. Radical excision is sometimes required because of the impossibility of conservative treatment such as shaving, mucosal skinning, or discoid resection. Bowel endometriosis should not be considered a cancer, and consequently maximal resection is not the objective. Rather, the goal would be to achieve functional benefit. As a result, resection must be as economic and cosmetic as possible. The laparoscopic approach has proved its superiority over the open technique, although mini-laparotomy is generally performed to prepare for the anastomosis. INTERVENTIONS: Total laparoscopic approach in patients with partial bowel stenosis, using the vagina for specimen extraction. CONCLUSION: This technique of intracorporeal anastomosis with transvaginal specimen extraction enables a smaller resection and avoidance of abdominal incision enlargement that may cause hernia, infection, or pain. When stenosis is partial, this technique seems particularly suited for treatment of bowel endometriosis requiring resection. If stenosis is complete, the anvil can be inserted above the lesion transvaginally.

PURPOSE: The aim of this study is to evaluate the impact of an expert monitoring on the quality and results of laparoscopic reversal of Hartmann's procedure (LRHP) performed by trainee surgeons by comparing their results to the expert's outcomes. METHODS: Forty-two LRHP were performed between 2000 and 2008 following a step-by-step, standardised, full laparoscopic procedure. Patients operated upon by a senior surgeon were compared to patients operated upon by trainee surgeons while being mentored by the senior surgeon. Operative time, conversion, complications and post-operative outcome were measured. RESULTS: Each group included 21 patients. All patients underwent LRHP successfully. Two procedures were converted. No significant difference was observed between the expert and the trainees: operative time, 132 min (SD ± 50) vs. 131 min (SD ± 47) and complications (2-14%), 4 vs. 2. Three complications required re-operation, and three other were treated medically, including one dilatation of an anastomosis. Post-operative outcomes were comparable (oral intake, 3 vs. 2 days; post-operative hospital stay, 6 vs. 7.5 days); no mortality occurred. CONCLUSIONS: Standardisation simplifies this difficult laparoscopic procedure and offers the same outcome whether it is performed by an expert or by mentored trainees. The complications were comparable to those occurring at experienced centres (anastomotic leak or stricture, ureteral injury, re-operation). The expert mentoring does not prevent all complications but can solve intra-operative technical problems, thus improving the trainee's confidence. Mentoring should be promoted as it can be performed locally or remotely using modern interactive technology.

BACKGROUND: Natural orifice specimen extraction (NOSE) in colorectal surgery prevents the need for an enlarged port site or minilaparotomy to extract the surgical specimen. The downside of this technique may be an increased risk of bacterial contamination of the peritoneal cavity from the external milieu. The aim of this study was to prospectively analyze the peritoneal bacterial contamination in NOSE and non-NOSE laparoscopic colorectal procedures. METHODS: Consecutive patients operated for sigmoid diverticulitis with laparoscopic approach and transanal extraction of the specimen from January to December 2010 at our university hospital were enrolled. Patients who underwent a laparoscopic sigmoidectomy in the same study period with conventional specimen extraction were used as reference. Peritoneal fluid samples were collected under sterile conditions at the end of the procedure and sent for gram stain as well as anaerobic, aerobic, and fungal cultures. RESULTS: Twenty-nine patients underwent laparoscopic sigmoidectomy for diverticulitis with transanal NOSE, while 9 patients underwent laparoscopic sigmoidectomy with conventional specimen extraction during the same period. The two groups were successfully matched 1:2 (17 NOSE and 9 non-NOSE) according age, sex, ASA, and Charlson comorbidity score. The contamination rate of peritoneal fluid was 100% vs. 88.9% in NOSE and non-NOSE procedures, respectively (P = 0.23). Overall and major complications rates were 27.6% vs. 11.10% (P = 0.41) and 5.08% vs. 11.1% (P = 1) in NOSE vs. non-NOSE procedures, respectively. In the NOSE group there was a statistically significant lower consumption of oral paracetamol (P = 0.007) and of oral tramadol (P = 0.02). CONCLUSIONS: Although a higher peritoneal contamination was found in the NOSE procedures, there were no significant differences in clinical outcomes relative to standard approach. Avoiding a minilaparotomy to extract the specimen resulted in a significantly lower postoperative analgesic requirement in the NOSE group.

INTRODUCTION: While experimental natural orifice transluminal endoscopic surgery (NOTES) sigmoid colectomies have been reported, pure NOTES anastomoses are restricted by the limited reach of commercially available circular staplers. MAGNAMOSIS is a set of self-orienting magnetic rings that can be delivered endoluminally throughout the colon to generate a compression anastomosis. Aim. To assess the feasibility of a pure NOTES transrectal (TR) and transgastric (TG) approach to perform any segmental colectomy. MATERIALS AND METHODS: One pig (50 kg) underwent the experimental procedure as follows: (a) creation of the TG access to the peritoneal cavity, (b) precise transluminal placement of the proximal MAGNAMOSIS ring, (c) creation of the TR access with the TEO and transrectal dissection of the sigmoid mesentery, (d) resection of the surgical specimen, (e) transrectal extraction of the specimen, (f) delivery and mating of the distal MAGNAMOSIS ring, and (g) closure of the TG and TR viscerotomies. The animal survived for 14 days at which time burst pressure and histology were performed. RESULTS: A pure NOTES TR and TG segmental colectomy was performed in 139 minutes. The postoperative course was uneventful. The animal had a formed bowel movement including the magnetic rings on postoperative day 5. Endoscopic examination at postoperative day 14 revealed a patent anastomosis. Necropsy revealed no abscess or signs of peritonitis. Burst pressure was >198 mm Hg. The histology showed a sealed anastomosis with mild inflammation. CONCLUSIONS: MAGNAMOSIS enabled a totally NOTES partial colectomy with combined TG and TR access. The flexible delivery options and low cost of manufacturing could make MAGNAMOSIS an attractive alternative to circular staplers.

INTRODUCTION: A transanal, posterior, retrorectal approach has been demonstrated as a feasible natural orifice transluminal endoscopic surgery (NOTES) total mesorectal excision (TME) procedure. The aim was to assess the feasibility of a transrectal approach with a completely retroperitoneal mobilization of the left colon and mesenteric vessels in an acute porcine model. MATERIALS AND METHODS: Eight pigs were used. A purse-string suture was made 3 cm above the anal sphincter. Next, the retroperitoneal, perirectal space was entered with an endoscope through a single (or twin) anterior lateral, transrectal viscerotomy. A retroperitoneal tunnel was created using pneumodissection or endoscopically guided dissection to the inferior mesenteric artery (IMA). The IMA was skeletonized and lymph nodes retrieved using the IsisScope or other instruments. The IMA was divided with the Ligasure, clips, or ligature performed with the IsisScope. The rectum was dissected transanally in the "Holy" plane. After achieving mobilization using a completely retroperitoneal approach, the peritoneal attachments were then divided and the rectosigmoid specimen exteriorized through the anus. An explorative laparoscopy was then performed to evaluate the quality of the mobilization. RESULTS: The procedure was successfully completed and the IMA correctly identified and ligated in all cases. In all but one case, no further mobilization was possible, even by a laparoscopic approach. CONCLUSIONS: Perirectal oncologic gateway to retroperitoneal endoscopic single-site surgery for left-sided colonic resections using both flexible and rigid surgical endoscopic platforms was feasible and reproducible in an acute porcine model. This technique might represent a step toward pure NOTES left-sided colorectal procedures.

During influenza A pandemia, the vaccination on pregnant women has raised many questions. Pandemia, easiness of travelling, and insufficient vaccinal coverage, expose these patients to infection which may have serious consequences on their pregnancy and on the child to born. On pregnant women, the precautionary principle is a priority and the evaluation of epidemiological risk is essential, in order to prevent adverses events. Prophylactic vaccinal administration against infections should be assessed with caution due to the little amount of available data. Its use will depend on the vaccine's composition and known side effects, the stage of pregnancy, as well as the benefit for the mother and the child to born, and her clinical history. Whatever the vaccine's nature, its administration never justifies a therapeutic abortion; its evolution must be closely followed to cover the occurrence of complication.

Purpose: To describe the number of prosthetic joint infections (PJIs) with late documentation and to identify associated factors. Methods: Bacterial PJIs with surgical management between November 2015 and November 2019 in a French center were analyzed. Results of short (72 h) and late culture (at 14 days) were analyzed. Results: A total of 160 PJIs were reported with 215 bacteria. Twenty-nine patients had late documentation (18.1%). The bacteria most involved were coagulase-negative staphylococci and Cutibacterium spp. (60%). In multivariate analysis, late chronic PJI (odds ratio = 2.47) and antibiotic therapy before surgery (odds ratio = 3.13) were associated with late-documented infection. Conclusion: A better knowledge of the factors associated with late-documented infections is essential in order to simplify antibiotic treatment at the appropriate time.
Prosthetic joint infections (PJIs) are rare and occur in around 1% of cases. They are often complex and require multidisciplinary management. The identification of bacteria and the implementation of an effective intravenous antibiotic therapy as soon as the surgery is performed are important points in PJI management. Some bacteria take longer to be cultivated, which is why samples are cultured for at least 14 days after surgery. As soon as the bacteria have been identified, the antibiotic therapy can be taken orally to allow the patient to be discharged early from hospital. The aim of this study was to investigate the factors associated with a positive late culture (day 14 after surgery) compared with an early culture (day 3). We showed that patients who had received antibiotic therapy within 1 month before surgery and patients with chronic PJI (i.e., more than 1 year after surgery) were at greater risk of having long-culture-positive specimens. We also showed that late samples were more often positive for two types of bacteria (Cutibacterium acnes and coagulase-negative staphylococci). In practice, when early samples are positive, oral antibiotics are given rapidly, except for patients who have had prior antibiotic therapy or who have a chronic infection for whom other samples may be positive late (14 days). Moreover, in patients with negative early culture, oral antibiotic therapy active against Cutibacterium acnes and coagulase-negative staphylococci (the two main bacteria in late culture) could be prescribed, waiting for the result of late culture.

Internet has dramatically changed clinical practice and information sharing among the surgical community and has revolutionized the access to surgical education. High-speed Internet broadcasting allows display of high-quality high-definition full-screen videos. Herein, Internet access to surgical procedures plays a major role in continuing medical education (CME). The WeBSurg Web site is a virtual surgical university dedicated to post-graduate education in minimally invasive surgery. Its results measured through its members, number of visitors coming from 213 different countries, as well as the amount of data transmitted through the provider LimeLight, confirm that WeBSurg appears as the first Web site in surgical CME. The Internet offers a tailored education for all levels of surgical expertise as well as for all types of Internet access. This represents a global multimedia solution at the cutting edge of technology and surgical evolution, which responds to the modern ethos of "always, anywhere, anytime."

Segmental colectomy is an ideal procedure for natural orifice transluminal endoscopic surgery (NOTES). Transanal endoscopic approaches have enabled rectosigmoid colectomy through a viscerotomy that is resected with the specimen. To extend NOTES segmental colectomy to the entire colon and beyond, a rectal viscerotomy will have to be safely and effectively closed at the end of the procedure. A new technique for rectal viscerotomy closure using a circular EEA hemorrhoid and prolapse stapler with DST series technology (Covidien) is described.

INTRODUCTION: A novel technique for secure placement of the anvil for mechanical stapled anastomosis in the proximal colon without exteriorization of the bowel is described. METHODS: After standard laparoscopic segmental colonic mobilization, a needle-cannula from a percutaneous endoscopic gastrostomy kit is passed under direct endoscopic vision transparietally into the colon at the site intended for anvil placement. A wire passed through the cannula into the colon is then withdrawn endoscopically per ano. The stapler anvil is fixed to the wire and pulled back along the intestine before being positioned by traction through the needle puncture site. After distal specimen transection, a standard stapled anastomosis is performed. RESULTS: The technique is illustrated in 2 patients undergoing laparoscopic sigmoidectomy by either a single port or a multiport procedure with transanal specimen extraction. CONCLUSION: By positioning the anvil without colon exteriorization, this technique enables pure intraperitoneal colonic anastomoses that may advance natural orifice operating.
