Medication Abortion Follow-Up Rates in a Rural Population Before and After Introduction of a Remote Follow-Up Option

Background: Medication abortion (MAB) follow-up historically involves visiting a health care facility for ultrasonography or laboratory testing. In rural states such as New Mexico, many patients travel hours for MAB, making two visits burdensome. Studies demonstrate feasibility, safety, and patient preference for remote follow-up. Materials and Methods: We evaluated whether MAB follow-up by telephone had noninferior loss-to-follow-up (LTFU) rates compared with ultrasonography or laboratory follow-up in a rural population. This was a retrospective chart review of University of New Mexico MAB LTFU rates after changing to telephone follow-up (home group, n = 136). Patients were propensity-matched in a 1:2 ratio to a historical cohort (health care group, n = 272) to eliminate significant differences. We defined LTFU as no contact within 50 days. We evaluated complications requiring intervention, possible ongoing pregnancy, completion of the home follow-up protocol (7- and 30-day calls, high-sensitivity urine pregnancy test [UPT]), follow-up by intended method (home or health care), and number of call attempts. Results: LTFU rates for the home group (n = 23, 17%) were noninferior to the health care group (n = 60, 22%, p = 0.24). Rates of complications requiring intervention (p = 0.83) and possible ongoing pregnancy (p = 0.72) among the home group were similar to the health care group. Ninety-seven (71%) home group patients completed the initial call, 79 (58%) completed the UPT, and 86 (69%) completed the 30-day call. Ninety-five (70%) home group patients followed up by intended method, comparable with the health care group (n = 199, 73%, p = 0.56). Staff made a median of 3 (interquartile range: 2-4) calls per home group patient. Conclusions: Remote MAB LTFU rates were noninferior to in-person LTFU rates.

[Efficacy and safety of endoscopic diaphragm incision in children with congenital duodenal diaphragm]

Objective: To explore the efficacy and safety of endoscopic diaphragm incision in pediatric congenital duodenal diaphragm. Methods: Eight children with duodenal diaphragm treated by endoscopic diaphragm incision in the Department of Gastroenterology of Guangzhou Women and Children's Medical Center from October 2019 to May 2022 were enrolled in this study. Their clinical data including general conditions, clinical manifestations, laboratory and imaging examinations, endoscopic procedures and outcomes were retrospectively analyzed. Results: Among the 8 children, 4 were males and 4 females. The diagnosis was confirmed at the age of 6-20 months; the age of onset was 0-12 months and the course of disease was 6-18 months. The main clinical manifestations were recurrent non-biliary vomiting, abdominal distension and malnutrition. One case complicated with refractory hyponatremia was first diagnosed with atypical congenital adrenal hyperplasia in the endocrinology department. After treatment with hydrocortisone, the blood sodium returned to normal, but vomiting was recurrent. One patient underwent laparoscopic rhomboid duodenal anastomosis in another hospital but had recurred vomiting after the operation, who was diagnosed with double duodenal diaphragm under endoscope. No other malformations were found in all the 8 cases. The duodenal diaphragm was located in the descending part of the duodenum, and the duodenal papilla was located below the diaphragm in all the 8 cases. Three cases had the diaphragm dilated by balloon to explore the diaphragm opening range before diaphragm incision; the other 5 had diaphragm incision performed after probing the diaphragm opening with guide wire. All the 8 cases were successfully treated by endoscopic incision of duodenal diaphragm, with the operation time of 12-30 minutes. There were no complications such as intestinal perforation, active bleeding or duodenal papilla injury. At one month of follow-up, their weight increased by 0.4-1.5 kg, with an increase of 5%-20%. Within the postoperative follow-up period of 2-20 months, all the 8 children had duodenal obstruction relieved, without vomiting or abdominal distension, and all resumed normal feeding. Gastroscopy reviewed at 2-3 months after the operation in 3 cases found no deformation of the duodenal bulbar cavity, and the mucosa of the incision was smooth, with a duodenal diameter of 6-7 mm. Conclusion: Endoscopic diaphragm incision is safe, effective and less invasive in pediatric congenital duodenal diaphragm, with favorable clinical applicability.

[Analysis of solitary rectal ulcer syndrome in 7 children]

Objective: To analyze the clinical features, treatment and prognosis of solitary rectal ulcer syndrome (SRUS) in children. Methods: The clinical data of 7 children who were diagnosed with SRUS in Department of Gastroenterology in Guangzhou Women and Children' Medical Center from January 2019 to December 2021 were retrospectively analyzed. The clinical data including general demographics, clinical presentations, endoscopic and histologic features, treatment and outcome were extracted from hospital medical records. Results: The 7 patients were all males, and the age of onset was 6-12 years. The course before diagnosis was 2-36 months. The most common symptom was rectal bleeding (6 cases) and most common findings at initial colonoscopy were ulcer in 3 cases and protuberance in 4 cases, both located only in rectum. The intestinal histopathology of 5 cases showed characteristic fibromuscular obliteration of lamina propria. Five children were treated with mesalamine granules or suppositories, and 2 cases underwent local excision. The follow-up lasted for 5-24 months and found symptoms relieved in 5 cases, improved in 1 case, and no remission in 1 case. Colonoscopy after the treatment was performed in 5 children, among whom 2 cases achieved mucosal healing. Conclusions: SRUS in children is mainly presented with rectal bleeding, and has characteristic histological change of ulcer and protuberance in endoscopy. Pathology is crucial for diagnosis and differential diagnosis. Both the medical and surgical treatment are effective for SRUS.
