ABSTRACT

BACKGROUND: Ureteric injury (UI) is an infrequent but serious complication of colorectal surgery. Prophylactic ureteric stenting is employed to avoid UI, yet its efficacy remains debated. Intraoperative indocyanine green fluorescence imaging (ICG-FI) has been used to facilitate ureter detection. This study aimed to investigate the role of ICG-FI in identification of ureters during colorectal surgery and its impact on the incidence of UI. METHODS: A retrospective cohort study involving 556 consecutive patients who underwent colorectal surgery between 2018 and 2023 assessed the utility of routine prophylactic ureteric stenting with adjunctive ICG-FI. Patients with ICG-FI were compared to those without ICG-FI. Demographic data, operative details, and postoperative morbidity were analyzed. Statistical analysis included univariable regression. RESULTS: Ureteric ICG-FI was used in 312 (56.1%) patients, whereas 43.9% were controls. Both groups were comparable in terms of demographics except for a higher prevalence of prior abdominal surgeries in the ICG-FI group. Although intraoperative visualization was significantly higher in the ICG-FI group (95.3% vs 89.1%; p = 0.011), the incidence of UI was similar between groups (0.3% vs 0.8%; p = 0.585). Postoperative complications were similar between the two groups. Median stent insertion time was longer in the ICG-FI group (32 vs 25 min; p = 0.001). CONCLUSION: Ureteric ICG-FI improved intraoperative visualization of the ureters but was not associated with a reduced UI rate. Median stent insertion time increased with use of ureteric ICG-FI, but total operative time did not. Despite its limitations, this study is the largest of its kind suggesting that ureteric ICG-FI may be a valuable adjunct to facilitate  ureteric visualization during colorectal surgery.

ABSTRACT

BACKGROUND: First described by Parks and Nicholls in 1978, the ileal pouch-anal anastomosis (IPAA) has revolutionized the treatment of mucosal ulcerative colitis (MUC) and familial adenomatous polyposis (FAP). IPAA is fraught with complications, one of which is pouch-vaginal fistulas (PVF), a rare but challenging complication noted in 3.9-15% of female patients. Surgical treatment success approximates 50%. Gracilis muscle interposition (GMI) is a promising technique that has shown good results with other types of perineal fistulas. We present the results from our institution and a comprehensive literature review. METHODS: A retrospective observational study including all patients with a PVF treated with GMI at our institution from December 2018-January 2000. Primary outcome was complete healing after ileostomy closure. RESULTS: Nine patients were included. Eight of nine IPAAs (88.9%) were performed for MUC, and one for FAP. A subsequent diagnosis of Crohn's disease was made in five patients. Initial success occurred in two patients (22.2%), one patient was lost to follow-up and seven patients, after further procedures, ultimately achieved healing (77.8%). Four of five patients with Crohn's achieved complete healing (80%). CONCLUSION: Surgical healing rates quoted in the literature for PVFs are approximately 50%. The initial healing rate was 22.2% and increased to 77.8% after subsequent surgeries, while it was 80% in patients with Crohn's disease. Given this, gracilis muscle interposition may have a role in the treatment of pouch-vaginal fistulas.

ABSTRACT

BACKGROUND: Gracilis muscle interposition (GMI) has been associated with favorable outcomes in treating complex perianal fistulas. Outcomes of GMI may vary according to the fistula etiology, particularly between rectovaginal fistulas in women and rectourethral fistulas (RUF) in men. The aim of this study was to assess the outcome of GMI to treat RUF acquired after prostate cancer treatment. METHODS: This retrospective cohort study included male patients treated with GMI for RUF acquired after prostate cancer treatment between January 2000 and December 2018 in the Department of Colorectal Surgery, Cleveland Clinic Florida. The primary outcome was the success of GMI, defined as complete healing of RUF without recurrence. Secondary outcomes were length of hospital stay and postoperative complications. RESULTS: This study included 53 male patients with a median age of 68 (range, 46-85) years. Patients developed RUF after treatment of prostate cancer with radiation (52.8%), surgery (34%), or transurethral resection of the prostate (TURP) (13.2%). Median hospital stay was 5 (IQR, 4-7) days. Twenty (37.7%) patients experienced 25 complications, the most common being wound infection and dehiscence. Primary healing after GMI was achieved in 28 (52.8%) patients. Fifteen additional patients experienced successful healing of RUF after additional procedures, for a total success rate of 81.1%. Median time to complete healing was 8 (range, 4-56) weeks. The only significant factor associated with outcome of GMI was wound dehiscence (p = 0.008). CONCLUSIONS: Although the initial success rate of GMI was approximately 53%, it increased to 81% after additional procedures. Complications after GMI were mostly minor, with wound complications being the most common. Perianal wound dehiscence was significantly associated with failure of healing of RUF after GMI.

ABSTRACT

Several drugs and their associations are being used for adjuvant or complementary chemotherapy with the aim of improving results of gastric cancer treatment. The objective of this study was to verify the impact of these drugs on nutrition and on survival rate after radical treatment of 53 patients with gastric cancer in stage III of the TNM classification. A control group including 28 patients who had only undergone radical resection was compared to a group of 25 patients who underwent the same operative technique followed by adjuvant polychemotherapy with FAM (5-fluorouracil, Adriamycin, and mitomycin C). In this latter group, chemotherapy toxicity in relation to hepatic, renal, cardiologic, neurological, hematologic, gastrointestinal, and dermatological functions was also studied. There was no significant difference on admission between both groups in relation to gender, race, macroscopic tumoral type of tumor according to the Borrmann classification, location of the tumor in the stomach, length of the gastric resection, or response to cutaneous tests on delayed sensitivity. Chemotherapy was started on average, 2.3 months following surgical treatment. Clinical and laboratory follow-up of all patients continued for 5 years. The following conclusions were reached: 1) The nutritional status and incidence of gastrointestinal manifestation were similar in both groups; 2) There was no occurrence of cardiac, renal, neurological, or hepatic toxicity or death due to the chemotherapeutic method per se; 3) Dermatological alterations and hematological toxicity occurred exclusively in patients who underwent polychemotherapy; 4) There was no significant difference between the rate and site of tumoral recurrence, the disease-free interval, or the survival rate of both study groups; 5) Therefore, we concluded, after a 5-year follow-up, chemotherapy with the FAM regimen did not increase the survival rate.

ABSTRACT

The case of a patient with gastric adenocarcinoma with indication for gastrectomy is reported. The surgery took place without complications. A palliative, subtotal gastrectomy was performed after para-aortic lymph nodes compromised by neoplasm were found, which was confirmed by pathological exam of frozen sections carried out during the intervention. At the end of the gastroenteroanastomosis procedure, the patient began to show intense bradycardia: 38 beats per minute (bpm), arterial hypotension, changes in the electrocardiogram's waveform (upper unlevelling of segment ST), and cardiac arrest. Resuscitation maneuvers were performed with temporary success. Subsequently, the patient had another circulatory breakdown and again was recovered. Finally, the third cardiac arrest proved to be irreversible, and the intra-operative death occurred. Necropsy showed massive pulmonary embolism. The medical literature has recommended heparinization of patients, in an attempt to avoid pulmonary thromboembolism following major surgical interventions. However, in the present case, heparinization would have been insufficient to prevent death. This case indicates that it is necessary to develop preoperative propedeutics for diagnosing the presence of venous thrombi with potential to migrate, causing pulmonary thromboembolism (PTE). If such thrombi could be detected, preventative measures, such as filter installation in the Cava vein could be undertaken.

ABSTRACT

It is presented the experience of 126 cases of acute appendicitis treated by a videolaparoscopic appendectomy using a 12 mm endostapler with 4 lines of staples and a linear cutting device in the middle. It has been used two trocars (5 mm) at the left side and one other (12 mm) trocar at the umbilicus. In the first cases other dispositions were used but this one seemed to be better. Through the left trocars, a dissection is promoted, isolating the appendix, its base and its mesentery, in which a small hole is made, close to the base. Through this hole, it is passed one of the sides of the 12 mm stapler. The device promotes the bilateral stapling and cuts the appendix at its base. The stapler is reloaded with vascular staples and then the mesentery is stapled and cut by the same way. It is a very fast method. Besides, the laparoscopic option gives the opportunity to equally treat appendicitis at unusual positions, to examine other pelvic organs (eventually treating diseases) and to aspirate secretions under direct view, anywhere in the cavity. The specimen is taken out of the cavity inside a plastic bag and we had no case of infection at the trocar sites. Only in 3 cases there were conversion to open surgery, due to difficult dissection and identification of structures, in all of them with very advanced disease and necrosis. It is concluded that this method is fast, safe, easy (although more expensive) and can be utilized routinely, at least in the first approach of the treatment of acute appendicitis.
