The da Vinci SP Surgical System (SP) received regulatory approval for use in gynecological surgeries in Japan in 2023. Given the advantages of the precision of a robot, less pain, and the cosmesis of single-port surgery, the da Vinci SP is expected to be further used for minimally invasive surgeries. To the best of our knowledge, this is the first report of the use of SP for the treatment of rectal endometriosis with segmental bowel resection. An urban general hospital. Stepwise demonstration of the technique with narrated video footage. The patient was a 46-year-old woman presented with chronic pelvic pain, pain on defecation, and constipation. Magnetic resonance imaging showed uterine large fibroid, left ovarian endometrioma, and 38 mm of rectal endometriosis, with complete cul-de-sac obliteration. We made a 30-mm vertical incision at the umbilicus, then placed the access port, and inserted three articulating instruments and a camera. An assistant port was placed in the right lower quadrant for using the linear stapler. The surgical steps were completely identical to conventional multiport laparoscopic robotic surgery. This suggests that conventional laparoscopic or robotic skills are highly transferrable to SP. SP offer several advantages, including high-resolution three-dimensional visualization, articulating instruments, and improved dexterity and range of motion. In addition, the umbilical access port was particularly useful for proximal bowel resection, specimen retrieval, and anvil positioning during bowel resection. The total operative time was 216 minutes. The estimated blood loss was 100 ml without any complications. The uterine weight was 800 g. The postoperative course was uneventful, with no perioperative complications, including no postoperative bladder dysfunction or low anterior resection syndrome [1,2]. The use of SP with the access port for segmental bowel resection for rectal endometriosis is technically safe and feasible, with good cosmesis and less pain.

We, herein, report a surgical technique for laparoscopy-assisted jejunostomy tube placement in an infant using a loop needle device to fix the jejunum and abdominal wall. A 3-year-old boy with Down's syndrome underwent nutritional management by gastrostomy due to oral feeding difficulty after radical surgery for congenital duodenal stenosis and following bile duct stenosis. However, intractable gastrostomy site leakage emerged; hence, laparoscopy-assisted gastrostomy takedown and simultaneous laparoscopy-assisted jejunostomy tube placement were planned. After laparoscopy-assisted gastrostomy closure was performed, the jejunum was extracted through the umbilical trocar wound. A jejunostomy tube kit was inserted at the left side of the umbilicus. After tube insertion into the jejunum, the jejunostomy tube was wrapped with four interrupted sutures using the Witzel technique. Suture threads were extracted by percutaneous insertion of a loop needle device, and then, the jejunum was fixed to the abdominal wall. The post-operative course was uneventful. Percutaneous insertion of a loop needle device is useful for fixing a jejunostomy tube to the abdominal wall using the Witzel technique. Our technique is safe, secure and expected to reduce the risk of dislodgement of tube and peritonitis associated with jejunostomy tube placement.

Post-bariatric surgery hypoglycemia is usually seen in patients with a history of gastric bypass surgery [1], and few experience severe symptoms [2]. The pathophysiology of post-gastric bypass surgery hypoglycemia is not well understood, and many theories have been proposed: excessive GLP-1, nesidioblastosis, and increased glucose effectiveness [3]. Thus, the etiology of this condition is complex. Laparoscopic GBP reversal is a very unusual procedure and indications may include excessive weight loss, unexplained GI tract symptoms, and severe hypoglycemia. Hypoglycemia should be managed non-surgically at first, but in case of medical therapy failure, surgical options may be considered. Surgical options include gastrostomy tube placement, gastric bypass reversal [4], or gastric bypass reversal with concomitant sleeve gastrectomy [5-7]. A partial reversal was also mentioned in the literature [6]. Laparoscopic conversion to a sleeve gastrectomy for hypoglycemia is unusual and converting an open gastric bypass to a laparoscopic sleeve gastrectomy is exceptional, even never reported. In this video (run time 6 min and 48 s), we present our procedure, which was performed by adopting a new technique. A 52-year-old lady was referred to us for hypoglycemia following an open gastric bypass revision that was done in 2012. Her past surgical history includes 2 laparoscopic gastric band surgeries with subsequent removal of the bands, open bypass surgery in 2007 and open bypass surgery revision in 2012. History goes back to 12 months ago when the patient started complaining of fatigue, lassitude, and symptoms consistent with Whipple's triad. OGTT (oral glucose tolerance test) showed low glucose levels at 2 h (2.7 mmol/l) and at 3 h (3.3 mmol/l). Serum insulin level and C-peptide were normal. The patient was diagnosed as having early dumping syndrome (reactive hypoglycemia). She was started on sitagliptin 1 tab once daily with dietary changes. Despite this management, she was hospitalized several times for worsening of her symptoms. When referred to our department, the patient asked about the possibility of a laparoscopic intervention, since she has suffered a lot from her previous laparotomy incisions. The laparoscopic surgery intervention was discussed with the patient and it was a challenging option in this case. The patient was placed in the lithotomy position with the surgeon standing between the patient's legs. An 11-mm trocar was inserted above the umbilicus. Under vision, 4 other trocars were inserted: a 12-mm trocar in the right midclavicular line and three 5-mm trocars in the epigastrium, left anterior axillary line, and left midclavicular line, respectively. We started with adhesiolysis in order to identify the gastro-jejunostomy and to free the abdominal esophagus. A subtle hiatal hernia was also reduced. Then, the jejuno-jejunostomy was identified, and the alimentary limb was measured. The latter was 70 cm in length, and the decision was to resect it, keeping the jejuno-jejunal anastomosis in place. The gastric pouch was divided just above the gastro-jejunal anastomosis. The alimentary limb was then exteriorized. Then, the gastric remnant was freed from its omental attachment. The gastric remnant and the gastric pouch were calibrated with a 40-Fr Faucher tube, and appropriate sequential firing was done using endo-GIA. A gastro-gastrostomy was fashioned by the end of the sleeve division to create the gastric tube. The operative time was 245 min, with minor blood loss (less than 250 cc). The perioperative course was uneventful, with no intra-operative or post-operative morbidity. An upper GI series was done on post-operative day 2 and showed no evidence of leak. It has been 11 months since the procedure and the patient has become normoglycemic. Her last FBS was 4.4 mmol and she is currently free of symptoms. Post-bariatric surgery hypoglycemia is a challenging condition, for both surgeons and endocrinologists. Our patient has suffered severe symptoms that were refractory to medical treatment and dietary modifications. Few papers have discussed LGBP conversion to a sleeve gastrectomy for hypoglycemia, but results from small series are showing promising results. Our case was challenging because of the patient's previous multiple open surgeries and the technique we have adopted is unique, since we have fashioned the sleeve by firing 2 separate gastric pouches (gastric pouch and gastric remnant) to create a gastric tube and by performing a gastro-gastrostomy with intra-corporeal sutures.

Based on the theories of I-Ching and umbilicus-hologram, the navel acupuncture is considered as a new acupuncture therapy that only acupuncture at Shenque (CV 8). It has a good effect on the treatment of bi syndrome and provides a new treatment idea for bi syndrome. This article presents the definition, etiology and treatment of bi syndrome, and introduces the application of umbilical-holographic, the principle and method of positioning and needle-inserting, the adjustment of therapies and the analysis of cases, in order to introduce the idea of treating bi syndrome by I-Ching navel acupuncture.

Vaginal agenesis is a müllerian anomaly characterized by congenital absence of the vagina. In this case series, the authors describe a novel, minimally invasive technique using microport entry for treatment of complete vaginal agenesis. A balloon catheter is passed through a fenestrated perfluoroalkoxy polymer resin-supporting platform, then tied by a silk suture over the caudal end of the inserter. Two 4-mm microports are created intraumbilically; one to insert the scope and the other to introduce the catheter inserter that is advanced under direct vision. The inserter loaded with a catheter is passed across the pelvic floor to position the balloon at the vaginal dimple. The balloon is inflated and tightly positioned against the dimple. The perfluoroalkoxy polymer resin piece is clamped at the umbilicus. Traction is applied to the catheter stem and increased progressively to achieve desired vaginal depth. Twenty-two women aged 17-28 years with vaginal agenesis underwent microport vaginoplasty. Twenty-one women were diagnosed with müllerian agenesis and one patient with androgen insensitivity syndrome. Preoperative vaginal depth ranged between 0.5 and 3 cm. The procedure was well tolerated with no intraoperative or postoperative complications. Patients achieved neovaginal depth between 9 and 11 cm and penetrations scores increased to 80-90%. Microport vaginoplasty is a feasible and effective procedure for management of vaginal agenesis.
