Hospital management of colonic perforations complicating ambulatory outpatient colonoscopy via over-the-scope clips or surgery: a case series.

BACKGROUND: Colonoscopy is the standard of care for the diagnosis and treatment of many colonic disorders. Over the past few years, endoscopic closure of colonoscopy-related perforation has become more common. Endoscopic closure of perforation secondary to colonoscopy has been undertaken in patients in the hospital setting and often during the same colonoscopic procedure in which the perforation itself occurred. The aim of our study was to analyze our experience with emergency endoscopic closure of colonoscopy-related perforation with over-the-scope clip (OTSC) technique. METHODS: We report five cases of colonic perforation that occurred during colonoscopy in an outpatient facility remotely located from our hospital and then referred as an emergency to our institution for endoscopic closure. RESULTS: Bowel preparation was reported to be adequate in all cases. Prior to attempting endoscopic closure of colonic perforation, all patients were in stable clinical condition, early broad-spectrum antibiotic coverage was initiated, and a surgical consult was obtained. All patients had sigmoidoscopy and were found to have sigmoid colon perforations. In three cases, the perforations were closed successfully using an OTSC clip device 14 mm type t. Two patients were found to have greater than 4-cm sigmoid perforations with irregular margins, incompatible with OTSC closure, and were referred for emergency surgery. All patients had an uneventful course following either OTSC closure or surgery. CONCLUSIONS: Based on the characteristics of the five cases and a review of the literature, we suggest a practical approach for undertaking closure of colonic perforations occurring during colonoscopy in the outpatient setting, focusing on clinical criteria to determine eligibility of patients for attempted endoscopic closure and outlining required therapeutic and monitoring steps needed to optimize outcomes.

Predictors for Adherence to Multidisciplinary Follow-Up Care after Sleeve Gastrectomy.

INTRODUCTION: A considerable proportion of patients who undergo bariatric surgeries (BS) do not attend routine postoperative follow-up despite recommendations for such. Data are sparse regarding the various aspects of patient adherence to consultations following sleeve gastrectomy (SG). OBJECTIVES: To examine predictors of adherence to SG follow-up, reasons for attrition from follow-up, and the relationship between adherence to follow-up and weight loss results. METHODS: A retrospective cohort study was performed with a mean follow-up of 3 years. Data were collected from electronic medical records and telephone questionnaires. Adherence was defined both as a numerical variable (ranking 0-9 according to the number of pre-scheduled postoperative visits) and as a dichotomous variable (adherent and non-adherent groups). RESULTS: Of 178 patients, 46.63% were defined as "adherent," according to the dichotomous definition. Compared to the "non-adherent group," patients in the "adherent group" more regularly used vitamin D after the surgery, had fewer rehospitalizations, and reported a lower intake of sweetened beverages. The main reasons for attrition were work-related and difficulties in mobility. Adherence to postoperative follow-up was not found to be correlated to weight loss. Older age (OR = 1.04; p = 0.026) and postoperative side effects (OR = 2.33; p = 0.035) were found to be positive predictors for adherence, whereas rehospitalizations (OR = 0.08; p = 0.028) and ethnical minority status were negative predictors (OR = 0.42; p = 0.019). CONCLUSION: Adherence to postoperative follow-up was found to be associated with positive lifestyle behaviors; however, no correlation was found to mid-term weight loss outcomes.

Trans-fascial laparoscopic mesh fixation: a procedural comparison using the standard suture passer versus iMESH stitcher™ device.

INTRODUCTION: Laparoscopic mesh repair has become an increasingly common method for repairing incisional hernias. The current method for fixating mesh to the abdominal wall includes tacking the mesh to the peritoneum and fascia and suturing the mesh to the fascia with trans-fascial sutures. The iMESH Stitcher™ is a stitching device developed to both simplify and expedite this procedure by passing the suture from one arm of the iMESH stitcher™ to the other. The device enables a stitch to be created in three quick moves using only one hand. We compared both the efficacy and procedure time of trans-fascial mesh fixation when performed with the iMESH stitcher™ as compared to the standard suture passer method. METHODS: A mesh patch was installed on the internal abdominal wall of two pigs. Surgical residents and Medical students were participants in the study and were trained in both techniques. Each participant was asked to perform six fixations with each technique. The procedural time required for both fixation techniques was recorded. Participants were asked to assess subjectively the relative difficulty of each technique on a scale of 1-10 (10 = most difficult). RESULTS: Sixteen residents and students performed a total of 12 mesh fixations, each performing 6 fixations with each technique. Average mesh fixation suture time using the suture passer technique was 44 s for residents and 47 s for students. Average fixation suture time using the iMESH stitcherTM was 17 s for residents and 15 s for students. The average difficulty score for the suture passer technique was 6.1 as compared to 2.9 with iMESH stitcher™. CONCLUSION: Trans-fascial fixation with the iMESH Stitcher™ took significantly less time than the standard suture passer method. The iMESH Stitcher™ significantly simplifies the procedure of transfascial fixation and potentially reduces technical difficulties.

[Tuberculous meningitis in AIDS--diagnosis and treatment].

The increase in prevalence of tuberculous meningitis during the past decade has been attributed in part to the increase of AIDS. Failure to diagnose HIV can cause irreversible damage and even death. We describe a man with AIDS admitted through the emergency room because of high fever and headaches for more than a month, He was cachectic and had nuchal rigidity without major neurological deficit. Brain imaging was normal and lumbar puncture showed neutrophils, lymphocytes, hypochloremia, elevated protein, and decreased glucose; cryptococcal antigen was negative but acid-fast staining was positive. Anti-TB chemotherapy was started using 4 drugs and dexamethasone was also given. Considerable improvement in his general condition followed rapidly. Use of corticosteroids in tuberculous meningitis has been a major issue. They are added to antimicrobial agents in order to decrease reactivity of inflammatory mediators and thus reduce central nervous system damage. We review several controlled studies in which steroids were added to treat tuberculous meningitis. The conclusions of most were that they decrease morbidity and mortality, especially of those moderately to severely ill. Most considered as ungrounded the possibility of exacerbating latent tuberculous, or any other opportunistic infection outside the central nervous system. However, it is currently recommended to add prednisone, 1 mg/kg/d for 2-4 weeks when initiating anti-tuberculous treatment.
