RESUMO
Background: Little data is available about colon laparoscopic surgery in low mid-income countries. The aim of this study was to audit the status and results of laparoscopic colon cancer surgery in Morocco. Patients and methods: This was a prospective study performed at 4 academic departments in Morocco between January 1, 2018, and March 31, 2020. All adult patients who underwent elective right or left colonic resection for colon adenocarcinoma were included. The main outcomes were the rate of laparoscopic surgery (LS) and the comparison of its short-term outcomes with open surgery (OS). Results: Among 121 patients included, 52 (43%) underwent laparoscopic resection (0-49.3%). Five surgeons (29%) performed at least one laparoscopic resection. There were more left colectomies in the laparoscopic group (71.2% vs. 39.1%. p = 0.0004), and more extended resections (23.1% vs. 40.6%. p = 0.043) and T4 stage (19% vs. 37.5%. p = 0.037) in the open group. There were no differences in 90-days overall and serious complications. OS patients had significantly more harvested lymph nodes (14 vs. 18. P = 0.007) and higher median surgical margins (6 cm vs. 9 cm. P = 0.003) than LS patients. Conclusions: LS for colon cancer in Morocco is performed by few surgeons, who apply strict patient selection for laparoscopic cases. It was associated with lower quality resections compared to open surgery. There are still many challenges requiring more focus on training, certification, centralization and standardisation of care across the nation.
RESUMO
The spectrum for gastrointestinal tract mesenchymal tumours includes leiomyomas, leiomyosarcomas, gastrointestinal stromal tumours (GISTs) and schwannomas. Schwannomas (also known as neuroma, neurilemmomas or neurinomas of Verocay) are well-known slow-growing, benign neoplasms that originate from nerve plexuses within a Schwann cell sheath. They can arise anywhere along the course of the peripheral nerve and are frequently reported around the head and neck, brachial plexus and along the gastrointestinal tract. Usually, these tumours are detected as solitary; however, they can occur at multiple sites around the body. Schwannomatosis (multiple schwannomas) is usually associated with neurofibromatosis type 2; the pathogenesis is triggered by mutations of the neurofibromatosis 2 tumour suppressor gene resulting in a loss of its function. Solitary gastric schwannomas are rare lesions that arise from the nerve plexus of the gastric wall. Frequently they are detected incidentally or may present with nonspecific abdominal pain or bleeding. This paper reports the case of a 79-year-old patient diagnosed with gastric schwannoma after presenting with abdominal pain. Gastric schwannomas should be taken into consideration while making a differential diagnosis of lesions that are gastric mesenchymal tumours, which span a broad spectrum. Gastric schwannomas are typically benign, considerably less common than gastric GISTs, and have an excellent prognosis following excision.
