Colchicine is mainly used in the treatment of acute gout attack, acute attack of chronic gout and other diseases in clinic. But the drug has high toxicity (highly toxic), the therapeutic dose is very close to the toxic dose, and there is no special effect after poisoning drug detoxification. The clinical manifestations of early patients after poisoning are not specific, which brings some difficulties and challenges in clinical diagnosis and treatment, and virtually increases the probability of death from drug poisoning. The drug poisoning is still sporadic reports. On September 1, 2020, a patient with acute colchicine poisoning was admitted to People's Hospital of Songtao Miao Autonomous County. This patient is the one with the longest poisoning time that can be retrieved by authoritative medical journals. After treatment, the patient was cured and discharged. This article reported the experience of diagnosis and treatment.

Objective: To investigate the safety and feasibility of 3D laparoscopic surgery via transrectal extraction of specimens without abdominal incision in the treatment of slow transit constipation (STC)., Methods: From May 2015 to January 2017, 8 STC patients (6 females and 2 males) with informed consent were selected to receive subtotal colectomy with 3D laparoscopy as the no-incision incision group, in which the initial part of ascending colon and rectum were end-to-end anastomosed directly after extraction of the specimen through the rectum. Twelve STC patients (9 females and 3 males) undergoing traditional subtotal colectomy with 3D laparoscopy were selected as the traditional group by case matching method (gender, age, BMI, the difference of receiving operation time less than 12 months, same surgeon team). Perioperative parameters (operation duration, intraoperative blood loss, exhausting time, postoperative hospital stay, complications, postoperative pain score and additional pain management), inflammation index at postoperative day 1 and day 3 (leukocyte, procalcitonin, interleukin 6, C-reactive protein), postoperative peritoneal infection, wound healing, short-term and long-term efficacy, patient satisfaction evaluation (subjective hundred-mark system) at postoperative one year were compared between two groups., Results: There were no significant differences between two groups in operation duration, intraoperative blood loss, exhausting time, postoperative hospital stay and morbidity of complication (all P>0.05). Significantly lower pain scores at postoperative 6-hour (median 3.0 vs. 4.5, U=23.0, P=0.042), lower ratio of additional analgesic at postoperative day 1(1/8 vs. 7/12, P=0.040) were found in the no-incision group. Leukocyte level at postoperative day 1 was significantly lower in the no-incision group [(11.0±3.5)×10 9 /L vs. (14.7±3.6)×10 9 /L, t=-2.281, P=0.035]. C-reactive protein concentration at postoperative day 3 was not significantly different between two groups but with different trend [median 78.1(0.1 to 154.0) mg/L vs. 22.0 (7.0 to 55.9) mg/L,U=33.0, P=0.047]. There were no significant differences of interleukin-6 and procalcitonin between two groups(all P>0.05). All the patients had follow-up for 14-31 months. Subjective effectiveness score was 90±9 in the no-incision group and 94±6 in the traditional group without significant difference(t=-1.099, P=0.286). No long-term complications associated with abdominal infection was observed in the no-incision group., Conclusion: 3D laparoscopic subtotal colectomy via transrectal extraction of specimens without abdominal incision in the treatment of STC has similar short-term and long-term efficacies compared with traditional laparoscopic assisted surgery, and does not increase the probability of abdominal contamination.

Objective: To introduce the use of a self-made specimen protective sleeve in laparoscopic resection for upper or mid rectal cancer and sigmoid colon cancer with transrectal specimen extraction surgery and the improvement of implantation method, so as to avoid and reduce bacterial contamination and tumor cell dissemination in abdominal cavity., Methods: During June 2015 and May 2017, 48 cases of high located rectal or sigmoid colon cancer were operated laparoscopically with natural orifices specimen extraction surgery (NOSES) using a self-made specimen protecting sleeve. Operation indication: (1) Rectum and sigmoid colon cancer with the distance of more than 6 cm from tumor inferior margin to dentate line. (2) The maximum diameter of intestine together with mesangial and tumor <7 cm by intraoperative judgment. (3) No anal and distal rectal surgery, no anorectal stenosis or lack of expansion capacity caused by trauma. (4) No ulcerative colitis, Crohn's disease or radiation proctitis. After transecting the rectum, the specimen protective sleeve was inserted through the right lower 12 mm main Trocar (This sleeve was tailored from the laparoscopic protective sleeve produced by China 3L Corporation, which was intercepted with 25-35 cm from one end of the sleeve according to the length of distal rectal retention. One end was ligated and the other was open with a ligature band. About 5 ml paraffin oil was used to rinse and lubricate during the operation). The rectal stump retained 7-8 cm in abdominal cavity. The transanal ligation part of the protective sleeve was cut off, then the stapler nail seat was inserted and specimen was pull out through the sleeve and rectum., Results: There were 30 males and 18 females. The average age was (64.5±14.1) years, the BMI was (25.4±3.9) kg/m 2 , the tumor diameter was (3.3±1.1) cm, the maximum diameter of specimen was (5.4±1.5) cm and the length of specimen was (18.6±4.3) cm. Among these 48 cases, specimens of 36 patients were pulled out through inside of the sleeve easily, while specimens of 12 patients were quite difficult with resistance. Of 12 cases, 7 needed the help of transverse forceps, 4 needed to make 1 cm incision in pull-through bowel and insert a suction to decrease the volume of large specimens with gathering of gas and fluid, and 1 received small abdominal incision to remove specimen and perform intestinal reconstruction due to big specimen (the diameter of tumor and mesentery was 7.5 cm). Specimen tears of 6 patients didn't result in dissemination thanks to the specimen protecting sleeve. The operation time was (113.2±76.1) min, the bleeding amount was (38.5±17.3) ml, the time to first oral intake was (47.9±4.4) h, and the postoperative hospitalization length was (8.5±1.7) d. Anastomotic leakage occurred in 1 case (2.1%). No intra-abdominal and trocar infection, and obstruction were found., Conclusion: The use of protective sleeve and the improvement of the method of intraperitoneal implantation can effectively reduce the abdominal contamination during the specimen extraction. It can be applied to big specimens as well.
