Long-Term Anorectal Manometry Outcomes After Laparoscopic and Transanal Total Mesorectal Excision.

Background: During transanal total mesorectal excision (TaTME), sustained dilation of the anal canal occurs, which can cause anatomical and functional damage to the sphincter complex. This study aimed to analyze the impact of laparoscopic total mesorectal excision (LaTME) and TaTME in anorectal sphincter function. Materials and Methods: An observational study was conducted comparing two cohorts of patients who underwent LaTME or TaTME for rectal cancer. The two groups were paired for comparison based on age, gender, and distance of the neoplasm to the anal margin. The anorectal function was assessed by manometry before surgery and at least 6 months after primary intervention or stoma closure. The intestinal function was assessed using the low anterior resection syndrome (LARS) score. Results: Twenty-two patients were included. There were no significant differences in baseline characteristics between groups except for the time between surgery and testing. A decrease in the mean resting and squeeze pressures between pre- and postoperative manometry was observed in both the treatment groups, the difference being only significant in the squeeze pressure values (TaTME P = .003; LaTME P = .004). After surgery, squeeze pressure reduction correlated with a worsening of the LARS point count (rho 0.587; P = .004). The time elapsed since surgery was negatively correlated with the LARS point count (rho -0.696; P = .001) and the difference between pre- and postoperative mean squeeze pressures (rho -0.499; P = .018). Conclusion: Manometric findings after TME are comparable between the laparoscopic and the transanal approach. Deterioration of both anal sphincter function and LARS improves with time after surgery.

Ischemic colitis and short bowel disease due to choronavirus disease 2019 (COVID 19).

COVID-19 has spread worldwide, with more than 2.5 million cases and over 80,000 deaths reported by the end of April 2020. In addition to pulmonary symptoms, gastrointestinal symptoms have been increasingly recognized as part of the disease spectrum. COVID-19-associated coagulopathy has recently emerged as a major component of the disease, leading to high morbidity and mortality. Ischemic colitis has been reported to be associated with a hypercoagulable state, However few cases have been reported of COVID-19 associated with ischemic colitis. We would like to report a case of a 53 year old man with medical history of type 2 diabetes, and hypercholesterolemia, with ishchemic colitis as first manifestation of infection of COVID 19.

Incidence and Risk Factors of Incisional Hernia After Single-Incision Endoscopic Surgery.

Introduction: Abdominal wall complications are one of the most controversial issues regarding single-incision endoscopic surgery. The aim of this study was to analyze the incidence and risk factors of incisional hernia after single-incision endoscopic cholecystectomy. Materials and Methods: An observational retrospective study was performed, on a cohort of patients cholecystectomized laparoscopically through a transumbilical single incision due to gallbladder lithiasis or polyps. Postoperative complications were analyzed, with special interest in the incisional hernia rate, whose results were assessed in the long-term follow-up. Univariate and multivariate analyses were also performed to evaluate possible variables associated with the appearance of incisional hernia. Cumulative sum charts (CUSUM) were used to identify trends in the incisional hernia risk. Results: Some 109 patients were included in the study. With a mean follow-up of nearly 38 months, an incisional hernia incidence of 5.5% was found, with 67% being diagnosed during the first year of follow-up. In the Cox regression analysis, two variables showed an independent association with the emergence of incisional hernia, body mass index (hazard ratio [HR] 1.30; 95% confidence interval [CI 1.053-1.606]; P .015), and wound infection (HR 26.32; [3.186-217.40]; P .002]. CUSUM charts showed a decrease in the risk of incisional hernia after the first 10 cases. Conclusions: Single-incision endoscopic cholecystectomy is associated with a substantially high risk of postoperative incisional hernia (5.5%).

European association for endoscopic surgery (EAES) consensus statement on single-incision endoscopic surgery.

BACKGROUND: Laparoscopic surgery changed the management of numerous surgical conditions. It was associated with many advantages over open surgery, such as decreased postoperative pain, faster recovery, shorter hospital stay and excellent cosmesis. Since two decades single-incision endoscopic surgery (SIES) was introduced to the surgical community. SIES could possibly result in even better postoperative outcomes than multi-port laparoscopic surgery, especially concerning cosmetic outcomes and pain. However, the single-incision surgical procedure is associated with quite some challenges. METHODS: An expert panel of surgeons has been selected and invited to participate in the preparation of the material for a consensus meeting on the topic SIES, which was held during the EAES congress in Frankfurt, June 16, 2017. The material presented during the consensus meeting was based on evidence identified through a systematic search of literature according to a pre-specified protocol. Three main topics with respect to SIES have been identified by the panel: (1) General, (2) Organ specific, (3) New development. Within each of these topics, subcategories have been defined. Evidence was graded according to the Oxford 2011 Levels of Evidence. Recommendations were made according to the GRADE criteria. RESULTS: In general, there is a lack of high level evidence and a lack of long-term follow-up in the field of single-incision endoscopic surgery. In selected patients, the single-incision approach seems to be safe and effective in terms of perioperative morbidity. Satisfaction with cosmesis has been established to be the main advantage of the single-incision approach. Less pain after single-incision approach compared to conventional laparoscopy seems to be considered an advantage, although it has not been consistently demonstrated across studies. CONCLUSIONS: Considering the increased direct costs (devices, instruments and operating time) of the SIES procedure and the prolonged learning curve, wider acceptance of the procedure should be supported only after demonstration of clear benefits.

El 19,7% de los servicios de cirugía al que pertenecen los encuestados tiene perfil en RR. SS. Entre las utilidades profesionales destacan las actividades formativas (87%) y el contacto con otros profesionales (84%). El 14,1% de los encuestados utilizan RR. SS. para relacionarse con los pacientes. Conclusiones: Las RR.SS. son útiles para la divulgación de información sobre eventos científicos y actividades formativas, la actualización y adquisición de conocimientos y la comunicación entre profesionales. Aspectos como la privacidad o la relación con los pacientes representan una barrera en el uso de RR. SS

Introduction: The use and utility of social media (SM) among Spanish general surgeons is unknown. Methods: Between October and December 2017 an online survey was carried out to the members of the Spanish Association of Surgeons, in which data on the profile of use and opinion on the usefulness of SM were collected. Results: 360 valid responses were obtained, 310 from surgeons who had an active SM profile. The most popular networks were: Facebook (86%), LinkedIn (61,6%), YouTube (60,6%) and Twitter (54,2%). LinkedIn and Twitter stood out as the most used SM for professional purposes. Surgeons with a SM profile were younger (42.4 ± 11 years versus 51.6 ± 8 years; P < .001). Gender did not show influence on presence in SM. The majority of respondents have profiles in more than one network (3.6 ± 1 accounts) and 73.5% reported daily access to them; 19.7% of the surgery departments to which the respondents belong have a SM account. Among SM utilities in the professional field, training activities (87%) and connectivity among professionals (84%) were the most outstanding; 14.1% of respondents use SM to interact with patients. Conclusions: SM is useful as a tool for the acquisition, updating and dissemination of scientific knowledge, also proving valuable as a new form of interaction among surgeons. Other issues such as privacy or surgeon-patient relationship represent a barrier to its use

Oxytocin discontinuation after the active phase of induced labor: A systematic review.

BACKGROUND: Oxytocin is the most widely used drug in the induction of labor, but it could have potential adverse effects that derive from uterine hyperstimulation. AIM: To determine the benefits and drawbacks of oxytocin continuation versus oxytocin discontinuation after the active phase of induced labor. METHODS: We systematically searched Pubmed, EMBASE, Scopus, ClinicalTrials.gov and Cochrane Library Plus until October 2017, for randomized controlled trials comparing oxytocin continuation with oxytocin discontinuation when the active phase of labor is reached were included. Data was collected by three reviewers and quality of the included studies assessed using the methodology recommended in the Cochrane Handbook. StatsDirect software was used to calculate risk ratios for binary variables and weighted mean differences for continuous variables. A fixed-effects or random-effects model was used as appropriate. RESULTS: Nine studies were selected including 1538 women, 774 in the oxytocin continuation group and 764 in the oxytocin discontinuation group. The incidence of cesarean sections (14.3% vs. 8.6%; relative risk, 1.67; 95% confidence interval: 1.25-2.23), uterine hyperstimulation (12.4% vs. 4.7%; relative risk, 2.59; 95% confidence interval: 1.70-3.93) and nonreassuring fetal heart rate (19.2% vs.12.5%; relative risk, 1.55; 95% confidence interval: 1.18-2.02) were significantly higher in the oxytocin continuation group. An increase in the duration of the second stage of labor in the oxytocin discontinuation group was observed (pooled mean difference, -7.03; 95% confidence interval: -9.80 to -4.26). CONCLUSIONS: After the active phase of induced labor, oxytocin continuation increases the risk of cesarean section, uterine hyperstimulation and alterations to the fetal heart rate.

Outcomes after laparoscopic ventral hernia repair: does the number of previous recurrences matter? A prospective study.

BACKGROUND: It is not yet clearly known whether laparoscopic ventral hernia repair (LVHR) is superior to the open approach in recurrent hernias. The aim of this study is to determine the safety and efficacy of laparoscopic technique for ventral hernias and investigate whether these outcomes are affected by the number of previous failed repairs. METHODS: Data from 124 consecutive patients who underwent LVHR using a standardized technique between September 2007 and June 2014 were collected prospectively. In all repairs, a composite prosthesis was tailored to overlap the defect by at least 5 cm and fixed with a double crown of spiral tacks. Clinical follow-up visits were performed at 1 week, 1, 6, and 12 months, and yearly thereafter. Patients were classified in 3 groups (0, 1, and ≥ 2) according to the number of previous hernia repairs for further statistical analysis. RESULTS: Long-term surveillance was available in 116 (93%) patients. Of these, 96 (82.8%) were recurrent hernias. There were 2 (1.7%) conversions, both in recurrent cases, and in 3 (2.6%) patients a hybrid access was used. Mean operating time was 55 min. There was an overall postoperative complication rate of 16%, with no mortality. During a mean follow-up of 30 (range 20-90) months, 3 (2.6%) recurrences were diagnosed 6, 8, and 9 months after surgery, respectively. A univariate analysis related to demographic, clinical, and perioperative variables did not find any significant relationship between the number of previous recurrences and operating time, conversion rate, hospital length of stay, overall morbidity, or recurrence. CONCLUSIONS: This study suggests that laparoscopic approach in recurrent incisional hernias is a safe and feasible alternative to open techniques. Furthermore, our experience supports the idea that LVHR may be the best option for recurrent cases in properly selected patients, independently of the number of previous recurrences.

Single-incision laparoscopic bariatric surgery: a systematic review.

BACKGROUND: Single-incision laparoscopic surgery has sparked a great deal of interest in the surgical community in recent years, including bariatric surgery. However, we still do not definitively know if this type of surgical approach provides benefits over conventional techniques without increasing morbidity and mortality. OBJECTIVE: To evaluate the safety and efficacy of single-incision laparoscopic bariatric surgery (SILBS) compared with conventional laparoscopic bariatric surgery (CLBS). MATERIALS AND METHODS: We searched the most important databases. Randomized clinical trials and observational studies comparing SILBS with CLBS were included. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. RESULTS: Fourteen studies complied with the inclusion criteria for our analysis, which included 2357 patients (1179 SILBS group versus 1178 CLBS group). The duration of surgery was longer in the SILBS group and no major intraoperative complications were observed in these series. A small improvement in postoperative pain was indicated in the SILBS group. The overall morbidity rate was 5% in the SILBS group and 4.8% in the CLBS. There was 1 perioperative death in 1 study, which occurred in an adjustable gastric banding (AGB) group, at .1% of all cases of AGB and .005% of all SILBS cases. When cosmesis was evaluated, patients in the SILBS group were more satisfied with the scar outcome. CONCLUSION: SILBS is a feasible technique to use in selected patients. However, there is insufficient evidence to recommend its widespread use compared with a conventional approach. More studies are needed to analyze the safety of this technique and its possible benefits.

Pancreaticogastrostomy versus pancreaticojejunostomy after pancreaticoduodenectomy: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The aim of this systematic review was to compare postoperative outcomes between pancreaticogastrostomy and pancreaticojejunostomy after pancreaticoduodenectomy. METHODS: Six databases were systematically reviewed to identify randomized controlled trials comparing pancreaticogastrostomy and pancreaticojejunostomy. Studies reporting postoperative complications, reoperations, and mortality were included (PROSPERO registration number CRD42013005383). RESULTS: The search provided a total of 1,646 references. Seven studies were selected including 1,121 patients, 562 in the pancreaticogastrostomy group and 559 in the pancreaticojejunostomy group. Overall incidence of pancreatic fistula and the incidence of more severe fistulas (grade B/C) were lower in the pancreaticogastrostomy group (relative risk 0.67; 95% confidence interval (CI) 0.52 to 0.86; p = 0.002 and relative risk 0.61; 95 % CI 0.40 to 0.93; p = 0.02). Abdominal collections were more frequent in the pancreaticojejunostomy group. However, pancreaticogastrostomy was associated with an increased risk of postoperative intraluminal hemorrhage, and there were no differences in overall morbidity, reoperations, or mortality. CONCLUSIONS: In this systematic review and meta-analysis, a reduction in the incidence of postoperative pancreatic fistula in the pancreaticogastrostomy group was observed. Although this evidence comes from randomized trials, pancreaticogastrostomy cannot be considered superior to pancreaticojejunostomy due to the presence of clinical heterogeneity among studies and the absence of differences in overall morbidity, reoperations, and mortality.

Systematic review and meta-analysis of randomized controlled trials comparing single incision versus conventional laparoscopic appendectomy.

BACKGROUND: Single incision laparoscopic appendectomy (SILA) has been proposed as an alternative to conventional laparoscopic appendectomy (CLA). OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of SILA when compared with CLA through a systematic review. METHODS: We performed an electronic search of EMBASE, PubMed, MEDLINE, and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) that compared SILA with CLA were included. RESULTS: Six RCTs met eligibility criteria, which included a total of 800 patients, 401 in the SILA group and 399 in the CLA group. There were no significant differences in terms of overall complications (odds ratio [OR] 0.93; 95% confidence interval [CI] 0.59-1.47; p = 0.77). SILA had a higher technical failure rate (OR 3.30; 95% CI 1.26-8.65; p = 0.01) and required a longer operative time (mean difference [MD] 4.67; 95% CI 1.76-7.57; p = 0.002). SILA was associated with better cosmetic results (standardized MD -0.4; 95% CI -0.64 to -0.16; p = 0.001) and earlier return to normal activity (MD -0.64; 95% CI -1.09 to -0.20; p = 0.005), although these advantages should be taken with caution due to the small number of studies reporting these two items and the short follow-up in the evaluation of cosmetic results. There were no significant differences in terms of postoperative pain or length of hospital stay between groups. CONCLUSIONS: SILA is comparable to CLA in selected patients, although it is associated with a higher technical failure rate and longer operative time. Further randomized trials are needed to determine if SILA really offers benefits over CLA.

Colorectal anastomosis facilitated by the use of the LigaSure(®) sealing device: comparative study in an animal model.

BACKGROUND: Recently, there has been speculation about the possibility of fusing intestinal tissue using bipolar sealing devices. In this study we compare in a porcine model the anastomoses created using the LigaSure(®) device with those created with a stapler after section and closure of a rectal stump. METHODS: Thirty pigs underwent laparoscopic colorectal anastomosis. In group A (n = 15), the division of the intestine and distal stump closure were done with a 10-mm LigaSure Atlas(®) device. In group B, these steps were carried out using an endoscopic stapler. Subsequently, the colorectal anastomosis was performed using circular stapling in both groups. The 4-week follow-up included health status, weight gain, blood tests, X-rays, and colonoscopy. Anastomotic tissue was processed to study the mechanical tensile strength and histopathology. RESULTS: There was no difference in the rate of conversion to open surgery or in average operating time between the groups. In the sealing device group, there was a significantly higher rate of failure in rectal stump closure (p = 0.042). There was one death in group B due to anastomotic leak. There was no difference in adhesion formation or stenosis. Mid-section anastomosis area was 89.7 mm(2) in group A compared with 100 mm(2) in group B (p = 0.52). In tensile strength studies, the maximum load resisted by the sample was 13.8 ± 4.9 N (group A) versus 15.7 ± 4.4 N (group B) (p = 0.17). There was no difference between the groups in degree of reepithelialization, number of inflammatory cells, or the presence of microabscesses. CONCLUSIONS: Division and sealing of the rectal stump with the LigaSure(®) device is feasible in the proposed experimental model, but it is less reliable than conventional closure with a stapler, since it has a significantly greater failure rate. Therefore, The LigaSure(®) device should not be used for this purpose in the clinical setting as this could lead to serious and dramatic complications.

Multilayer myofascial-mesh repair for giant midline incisional hernias: a novel advantageous combination of old and new techniques.

BACKGROUND: The components separation technique has been proposed as the best solution when facing large abdominal wall defects. In counterpart, this sometimes comes at the price of high rates of wound complications and recurrence. Moreover, the components separation method alone seems insufficient for huge defects, in which it is impossible to reapproximate the rectus muscles without tension. For these cases, we illustrate a novel operation using a modified components separation technique. METHODS: Twenty-eight patients with giant midline incisional hernias were treated with a combination of the components separation (bilateral sliding rectus abdominis advancement flaps), an autologous multilayer repair, and a retromuscular mesh reinforcement. RESULTS: Twenty-four (85%) patients have been analyzed. Transverse defect size ranged from 15 to 25 cm (average, 18.8 cm). Wound complications occurred in nine (37%) cases; three of them required drainage of a subcutaneous abscess. After a mean follow-up of 22 (range, 12-48) months, one (4%) recurrence was identified. CONCLUSIONS: Multilayer myofascial-mesh repair was associated with a low recurrence rate, and wound complications were managed without issues. This approach is a reliable technique for most surgeons and may constitute a new part of the armamentarium for the repair of challenging defects.

Ergonomics in laparoendoscopic single-site surgery: survey results.

BACKGROUND: Ergonomic issues are frequently reported by surgeons performing laparoendoscopic single-site (LESS) surgery. However, few studies have analysed this issue. METHODS: We used a web format survey to evaluate the opinion of surgeons with experience in this laparoscopic technique. This survey collected demographic information, surgical experience, physical and psychological symptoms, and technical problems related to this type of surgery. RESULTS: Some 78 surgeons filled out the questionnaire. All participants had clinical experience in this type of laparoscopic approach, and 68 % had performed more than 30 procedures. Two or more musculoskeletal symptoms were reported during or after performing LESS surgery by 81 % of all surgeons. Surgeons with more experience in this approach reported fewer symptoms and technical difficulties. CONCLUSIONS: LESS surgery is accompanied by musculoskeletal problems and technical difficulties for surgeons. Technological advancements and greater surgical experience in the technique will alleviate these issues. More in-depth ergonomic studies are needed.
