AIM: To describe the technique of a modified extraperitoneal retrotransversalis end colostomy as part of a laparoscopic abdomino-perineal resection (APR). METHOD: The colostomy site is preoperatively chosen and intraoperatively used for a trocar. After the rectum has been mobilized the descending colon is freed. The peritoneal margin is gently grasped and the parietal peritoneum, extraperitoneal together with the transversalis fascia are separated from the transverse abdominal muscle fibres upwards for 3-4 cm aiming at the trocar site to form the extraperitoneal retrotransversalis canal...

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease; however, the frequency of recurrence can be reduced if curative surgery following adjuvant chemotherapy is applied. At present, adjuvant chemotherapy is uniformly performed in all patients, as it is unclear which tumor types are controlled best or worst. We investigated patients with recurrence to establish the optimum treatment strategy. METHODS: Of 138 patients who underwent curative surgery for PDAC, 85 developed recurrence...

Ovarian cancer is fairly unique in that ovarian carcinoma cells can detach and spread directly through peritoneal cavity. It has been unclear, however, how detached cancer cells survive in the peritoneum and form spheroid structure. We have recently reported that there is a strong correlation between Tumor-associated macrophages (TAMs)-associated spheroid and clinical pathology of ovarian cancer, and that TAMs promote spheroid formation and tumor growth at early stages of transcoelomic metastasis in orthotopic mouse models...

PURPOSE: "Endometriosis" is defined such as the presence of endometrial glands and stroma outside the uterine cavity. This ectopic condition may develop as deeply infiltrating endometriosis (DIE) when a solid mass is located deeper than 5 mm underneath the peritoneum including the intestinal wall. The ideal surgical treatment is still under search, and treatment may range from simple shaving to rectal resection. The aim of the present systematic review is to report and analyze the postoperative outcomes after rectosigmoid resection for endometriosis...

Cytotoxic CD8+ T (Tc) cells are the main executors of transformed and cancer cells during cancer immunotherapy. The latest clinical results evidence a high efficacy of novel immunotherapy agents that modulate Tc cell activity against bad prognosis cancers. However, it has not been determined yet whether the efficacy of these treatments can be affected by selection of tumoural cells with mutations in the cell death machinery, known to promote drug resistance and cancer recurrence. Here, using a model of prophylactic tumour vaccination based on the LCMV-gp33 antigen and the mouse EL4 T lymphoma, we analysed the molecular mechanism employed by Tc cells to eliminate cancer cells in vivo and the impact of mutations in the apoptotic machinery on tumour development...

We present a patient diagnosed with skin sarcoidosis, breast cancer, pulmonary tuberculosis, and peritoneal sarcoidosis with a past history of colorectal cancer. During stage work up for breast cancer, suspicious lesions on peritoneum were observed in imaging studies. Considering our patient's history and imaging findings, we initially suspected peritoneal carcinomatosis. However, the peritoneal lesion was diagnosed as sarcoidosis in laparoscopic biopsy. This case demonstrates that abdominal sarcoidosis might be considered as a differential diagnosis when there is a lesion suspected of being peritoneal carcinomatosis with nontypical clinical presentations...

There is growing appreciation of the importance of the mechanical properties of the tumor microenvironment on disease progression. However, the role of extracellular matrix (ECM) stiffness and cellular mechanotransduction in epithelial ovarian cancer (EOC) is largely unknown. Here, we investigated the effect of substrate rigidity on various aspects of SKOV3 human EOC cell morphology and migration. Young's modulus values of normal mouse peritoneum, a principal target tissue for EOC metastasis, were determined by atomic force microscopy (AFM) and hydrogels were fabricated to mimic these values...

Introduction Fungal infection of the peritoneum has become more common in recent years, the most common cause of which is Candida. Candida peritonitis is considered as a severe disease and is regarded as an independent risk factor for mortality in postoperative peritonitis. This study was planned to find out the clinical significance of Candida isolation on the outcome of the patients with peritonitis in terms of morbidity and mortality. Methods This prospective study included consecutive patients admitted and operated for secondary peritonitis over a two-year period in a tertiary care hospital in South India...

OBJECTIVES: The physiology of nearly all mammalian organisms are entrained by light and exhibit circadian rhythm. The data derived from animal studies show that light influences immunity, and these neurophysiologic pathways are maximally entrained by the blue spectrum. Here, we hypothesize that bright blue light reduces acute kidney injury by comparison with either bright red or standard, white fluorescent light in mice subjected to sepsis. To further translational relevance, we performed a pilot clinical trial of blue light therapy in human subjects with appendicitis...

Dimuth N Gunawardane, Philip W Allen
Peritoneal lipofuscinosis is a very rarely recognized condition occurring during pregnancy characterized by brown pigmentation of the omentum and peritoneum, a decidual reaction and benign mesothelial cells. The iron negative pigment, which is likely to be confused with hemosiderin in the hematoxylin and eosin stain, is lipofuscin. The seminar case, apparently the third published, arose in a 37-year-old woman who presented in October 2015 at 24 weeks pregnancy with abdominal pain. Investigations revealed a ruptured left ovarian cyst and rising serum carcinoembryonic antige levels...

Approximately 15% of colorectal cancer (CRC) cases exhibit microsatellite instability (MSI), which appears to be associated with unique biological behavior. The present study presents a case of appendiceal carcinoma associated with MSI that responded well to adjuvant chemotherapy. Clinical, pathological and immunohistochemical (IHC) characteristics have been described. The 60-year-old male patient had suffered from recurrent lower abdominal pain associated with abdominal distention for 6 months; then, following an acute attack, he was subjected to laparoscopic appendectomy...

Muscle-invasive bladder cancer (MIBC) has a tendency toward urothelial multifocality and is at risk for local and distant spread, most commonly to the lymph nodes, bone, lung, liver, and peritoneum. Pretreatment staging of MIBC should include imaging of the urothelial upper tract for synchronous lesions; imaging of the chest, abdomen, and pelvis for metastases; and MRI pelvis for local staging. CT abdomen and pelvis without and with contrast (CT urogram) is recommended to assess the urothelium and abdominopelvic organs...

OBJECTIVE: We investigate the impact of the bowel suspension technique (BST) on paralytic ileus and early intestinal obstruction (≤60days) after radical cystectomy (RC) with ileal orthotopic neobladder (IONB). METHODS: We retrospectively reviewed 310 patients who underwent RC with IONB for bladder cancer between 2001 and 2017. After forming the Studer IONB, ileal continuity was restored by side-to-side stapled anastomosis. Then, we suspended stapled anastomotic portion of bowel on the posterior peritoneum not to fall into the pelvic cavity...

Well-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis...
