ABSTRACT

OBJECTIVE: To demonstrate our application of the ghost ileostomy in the setting of laparoscopic segmental bowel resection for symptomatic bowel endometriosis nodule. DESIGN: Technical step-by-step surgical video description (educative video) SETTING: University Tertiary Hospital. Institutional Review Board ruled that approval was not required for this study. Endometriosis affects the bowel in 3% to 37% of all cases, and in 90% of these cases, the rectum or sigmoid colon is also involved. Infiltration up to the rectal mucosa and invasion of >50% of the circumference have been suggested as an indication for bowel resection [1]. Apart from general risks (bleeding, infection, direct organ injuries) and bowel and bladder dysfunctions, anastomotic leakage is one of the most severe complications. In women with bowel and vaginal mucosa endometriosis involvement, there is a risk of rectovaginal fistula after concomitant rectum and vagina resections. Hence, for lower colorectal anastomosis, the use of temporary protective ileostomy is usually recommended to prevent these complications but carries on stoma-related risks, such as hernia, retraction, dehydration, prolapse, and necrosis. Ghost ileostomy is a specific technique, first described in 2010, that gives an easy and safe option to prevent anastomotic leakage with maximum preservation of the patient's quality of life [2]. In case of anastomotic leakage, the ghost (or virtual) ileostomy is converted, under local anesthesia, into a loop (real) ileostomy by extracting the isolated loop through an adequate abdominal wall opening. In principle, avoiding readmission for performing the closure of the ileostomy, with all the costs related, means a considerable saving for the hospital management. Also, applying a protective rectal tube in intestinal anastomosis may have a beneficial effect [3]. These options are performed by general surgeons in oncological scenarios, but their use in endometriosis has never been described. INTERVENTIONS: In a 32-year-old woman with intense dysmenorrhea, deep dyspareunia, dyschesia, and cyclic rectal bleeding, a complete laparoscopic approach was performed using blunt and sharp dissection with cold scissors, bipolar dissector and a 5-mm LigaSure Advance (Covidien, Valley lab, Norwalk, Connecticut). An extensive adhesiolysis restoring the pelvic anatomy and endometriosis excision was done. Afterward, the segmental bowel resection was performed using linear and circular endo-anal stapler technique with immediate end-to-end bowel anastomosis and transit reconstitution. Once anastomosis was done, the terminal ileal loop was identified, and a window was made in the adjacent mesentery. Then, an elastic tape (vessel loop) was passed around the ileal loop, brought out of the abdomen through the right iliac fossa 5-mm port site incision and, fixed to the abdominal wall using nonabsorbable stitches. Finally, a trans-anal tube was placed for 5 days. The patient was discharged on the fifth day postoperatively without any complications. The tape was removed 10 days after surgery, and the loop dropped back. Two months after the intervention, the patient remains asymptomatic. CONCLUSION: Ghost ileostomy is a simple, safe, and feasible technique available in the setting of lower colorectal anastomosis following bowel endometriosis resection.

ABSTRACT

BACKGROUND & AIMS: Gastrointestinal (GI) manifestations have been increasingly reported in patients with coronavirus disease 2019 (COVID-19). However, the roles of the GI tract in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are not fully understood. We investigated how the GI tract is involved in SARS-CoV-2 infection to elucidate the pathogenesis of COVID-19. METHODS: Our previously established nonhuman primate (NHP) model of COVID-19 was modified in this study to test our hypothesis. Rhesus monkeys were infected with an intragastric or intranasal challenge with SARS-CoV-2. Clinical signs were recorded after infection. Viral genomic RNA was quantified by quantitative reverse transcription polymerase chain reaction. Host responses to SARS-CoV-2 infection were evaluated by examining inflammatory cytokines, macrophages, histopathology, and mucin barrier integrity. RESULTS: Intranasal inoculation with SARS-CoV-2 led to infections and pathologic changes not only in respiratory tissues but also in digestive tissues. Expectedly, intragastric inoculation with SARS-CoV-2 resulted in the productive infection of digestive tissues and inflammation in both the lung and digestive tissues. Inflammatory cytokines were induced by both types of inoculation with SARS-CoV-2, consistent with the increased expression of CD68. Immunohistochemistry and Alcian blue/periodic acid-Schiff staining showed decreased Ki67, increased cleaved caspase 3, and decreased numbers of mucin-containing goblet cells, suggesting that the inflammation induced by these 2 types of inoculation with SARS-CoV-2 impaired the GI barrier and caused severe infections. CONCLUSIONS: Both intranasal and intragastric inoculation with SARS-CoV-2 caused pneumonia and GI dysfunction in our rhesus monkey model. Inflammatory cytokines are possible connections for the pathogenesis of SARS-CoV-2 between the respiratory and digestive systems.

ABSTRACT

PURPOSE: Today, the rapid outbreak of COVID-19 is the leading health issue. Patients with cancer are at high risk for the development of morbidities of COVID-19. Hence, oncology centers need to provide organ-based recommendations for optimal management of cancer in the COVID-19 era. METHODS: In this article, we have provided the recommendations on management of locally advanced rectal cancer during the COVID-19 pandemic based on our experience in Shohada-e Tajrish Hospital, Iran. RESULTS: We recommend that patients with locally advanced rectal cancer should be managed in an individualized manner in combination with local conditions related to COVID-19. CONCLUSION: Our recommendation may provide a guide for oncology centers of developing countries for better management of locally advanced rectal cancer.
