Review
The gastrointestinal (GI) tract is efficient in transporting ingested material to the site of delivery in healthy subjects. A fine balance exists between peristaltic forces, the mixing and delivery of the contents, and sensory signaling. This fine balance is easily disturbed by diseases. It is mandatory to understand the pathophysiology to enhance our understanding of GI disorders. The inaccessibility and complex nervous innervation, geometry and mechanical function of the GI tract make mechanosensory evaluation difficult. Impedance planimetry is a distension technology that assesses luminal geometry, mechanical properties including muscle dynamics, and processing of nociceptive signals from the GI tract. Since standardized models do not exist for GI muscle function in vivo, models, concepts, and terminology must be borrowed from other medical fields such as cardiac mechanophysiology. The review highlights the impedance planimetric technology, muscle dynamics assessment, and 3 applied technologies of impedance planimetry. These technologies are the multimodal probes that assesses sensory function, the functional luminal imaging probe that dynamically measures the geometry of the lumen it distends, and Fecobionics that is a simulated feces providing high-resolution measurements during defecation. The advanced muscle analysis and 3 applied technologies can enhance the quality of future interdisciplinary research for gaining more knowledge about mechanical function, sensory-motor disorders, and symptoms. This is a step in the direction of individualized treatment for GI disorders based on diagnostic subtyping. There seems to be no better alternatives to impedance planimetry, but only the functional luminal imaging probe is currently commercially available. Wider use depends on commercialization of the multimodal probe and Fecobionics.

UNLABELLED
Cap polyposis is a gastrointestinal disease with multiple inflammatory polyps between the distal colon and rectum. Its symptoms overlap with inflammatory bowel disease with typical endoscopic features of multiple sessile polyps in the rectum and sigmoid colon, located at the apices of transverse folds. Microscopically, the polyps consist of elongated, tortuous, and distended crypts covered by a "cap" of inflammatory granulation tissue. In this report, we present a case of a 18-year-old male patient who underwent polypectomy for polyposis in multiple settings. He presented with one year of painless rectal bleeding and polyposis in a recto-sigmoid area on colonoscopy, with a single polyp in the sigmoid area and multiple polyps in the rectum. He was managed with immediate and interval polypectomy. Though cap polyposis is rare, it can be cured as it is laparoscopically resectable.

The mucocele of the appendix can be described as an obstructive dilatation of the appendix by an intraluminal accumulation of mucus. A 60-year-old diabetic male patient presented with chief complains of pain in right lower abdomen for the past 2 months which was dull in nature, not associated with fever, vomiting, diarrhea, constipation, or any urinary complains. Contrast-enhanced computed tomography (CECT) of the abdomen revealed appendiceal lumen distended, filled with fluid collection. There was abrupt narrowing seen at its junction with cecum. Features were suggestive of appendicular mucocele. The patient was taken up for exploratory laparotomy, and a distended turgid appendix, around 4 cm in diameter with dilated cecum, was found. Ileocecal resection was done followed by ileo-ascending colon side-to-side anastomosis using staplers. The histopathological examination report revealed an R0 resection. The patient was followed up for 3 years postoperatively with CECT of the abdomen and a colonoscopy yearly. There was no evidence of any recurrence in the follow-up.

Review
BACKGROUND AND AIMS
EUS-guided gastroenterostomy (EUS-GE) is effective in relieving gastric outlet obstruction. Several techniques used to create EUS-GEs have been described. However, these techniques are dependent on passing a guidewire beyond the obstruction. We describe a direct needle-puncture technique that allows for successful EUS-GE creation without a guidewire.
METHODS
The direct antegrade EUS-GE method often involves passing a guidewire and tube beyond the obstruction to distend the small bowel. An oblique echoendoscope is then positioned in the stomach to locate the distended small bowel. An electrocautery-enhanced lumen-apposing metal stent (LAMS) is used to create the anastomosis. However, in cases when neither endoscope nor guidewire can be passed across the obstruction, the direct needle-puncture technique can be used. With the oblique echoendoscope positioned in the stomach, a collapsed loop of small bowel is located adjacent to the gastric wall. A 19-gauge needle is used to puncture the gastric and small bowel wall. The small bowel is distended with a mixture of saline, methylene blue, and contrast via a standard water pump connected to the needle. An antispasmodic is administered, and an electrocautery-enhanced LAMS is then introduced into the working channel to create a gastroenterostomy using the freehand method.
RESULTS
The direct needle-puncture technique was performed in 4 patients for these indications: postsurgical inflammation causing gastric outlet obstruction (case 1), tumor infiltration causing gastric outlet obstruction (cases 2A and 2B), and pancreaticobiliary limb access in a duodenal switch (case 3). The video shows the technique performed in a patient with postsurgical inflammation and a patient with duodenal tumor infiltration.
CONCLUSIONS
The direct needle-puncture technique is useful for performing gastroenterostomy when the guidewire cannot be passed beyond the obstruction. It can also be used to gain access to a targeted bowel limb in altered anatomy for diagnostic and therapeutic purposes.

ANAMNESIS
We report on a 66-year-old patient who had had painful swelling of his left big toe for about 9 months with subjectively stopped growth.
EXAMINATION
Previously, bacteriological, and mycological smears and an MRI examination had not provided any groundbreaking findings, and previous antibiotic, antiseptic and anti-inflammatory therapies had not contributed to alleviating the symptoms.
DIAGNOSIS AND THERAPY
Based on the clinical findings with a reddened, piston-like distended distal phalanx with a raised proximal nail wall, we made the diagnosis of retronychia and performed a nail plate extraction.
CLINICAL COURSE
In the follow-up checks, which lasted more than two years, the patient was symptom-free with recovered nail growth.
CONCLUSION
As in the case presented, retronychia is often misdiagnosed. The knowledge of groundbreaking clinical and anamnestic parameters and the correct therapy options allows a quick, inexpensive, and long-term successful treatment.

Review
Hydrometrocolpos is a rare condition in which the uterus and the vagina are grossly distended with a retained fluid other than pus or blood. It may present during the neonatal period or later at puberty. Most cases reported earlier were stillbirths and were diagnosed only on autopsy. Antenatal diagnosis is now possible with the advent of ultrasound. An early diagnosis and speedy management is the key to survival. Many previous case reports have focused on the varied clinical presentations, multiple causes, associated syndromes and/or the radiological diagnosis of this condition. However, management options for different types of hydrometrocolpos have not yet been concisely discussed. We have reviewed the literature and tried to summarize the management options applicable to most case scenarios of hydrometrocolpos.

BACKGROUND
Floppy pouch complex (FPC) consists of disease phenotypes in patients with ileal pouches, including pouch prolapse, afferent limb syndrome, enterocele, redundant loop, and pouch folding. Our recent study demonstrated that lower body weight, lower peripouch fat, family history of inflammatory bowel disease (IBD), female gender, and dyschezia are risk factors for FPC patients with IBD. The aims of this study were to assess the relationship between pouch wall thickness and FPC, and to investigate the association between inflamed and non-inflamed pouch wall thickness.
METHODS
This case-control study included all eligible patients with FPC from our prospectively maintained, IRB-approved Pouchitis Registry from 2011 to 2017. We measured pouch wall thickness of fully distended pouches on cross-sectional abdominal and pelvic imaging. Patients with stoma and non-distended pouches were completely excluded. Risk factors for FPC were analyzed.
RESULTS
A total of 140 out of 451 patients from our were found to have fully distended pouches on imaging. Of the 140 patients, 36 (25.7%) were diagnosed as having FPC. We analyzed pouch wall thickness for each subcategory of FPC as well as non-FPC conditions. The thickness of pouch wall was follows: pouch prolapse (N = 19): 1.5 mm (1.5-2.0), afferent limb syndrome (N = 12): 1.5 mm (1.1-2.0), folded pouch (N = 4): 1.5 mm (1.1-1.9), and redundant pouch (N = 2): 1.3 mm (1.0-1.3). The control group (N = 104) consisting of normal pouch, pouchitis, cuffitis, Crohn's disease of the pouch, and pouch sinus with median pouch wall thickness of 1.5 mm, 2.3 mm, 2.0 mm, 2.0 mm, and 1.5 mm, respectively. There were significant differences in pouch wall thickness between normal or non-inflamed pouch versus pouchitis versus cuffitis versus Crohn's disease of the pouch with p values of 0.01, 0.04, 0.05, and 0.049, respectively.
CONCLUSION
Patients with FPC were shown to have thin pouch wall, which those with inflammatory conditions of the pouch tended to have thick pouch wall. These findings will have implications in both diagnosis and investigation of etiopathogenesis of these disorders.

Schnitzler's metastasis occurs due to the deposition of the tumor cells in the submucosa of the rectum, leading to rectal stenosis. We present a 60-year-old female who presented with abdominal pain, distension, and vomiting. Abdominal examination showed a distended abdomen and palpable bowel loops, and per rectal examination showed rectal stenosis. Imaging studies suggest rectal stenosis with carcinoma of the pancreas head. The patient was diagnosed with Schnitzler's metastasis with carcinoma of the pancreas head, which has not been reported in the literature. The patient underwent a diversion sigmoid colostomy and was planned for palliative chemotherapy after stenting the common bile duct.

Review
The main function of the knee bursae is to provide cushioning for the many periarticular ligaments, tendons, and osseous structures. Bursae can only be visualized when distended by fluid, therefore bursal anatomy is best evaluated by MR imaging using fluid-sensitive sequences. Knowledge of the normal bursal distribution is important to avoid incorrectly interpreting a distended bursa as a periarticular fluid collection or cyst. Bursal pathology usually results from trauma, chronic overuse, or inflammation, and may be associated with an underlying intra-articular process, given the presence of synovial lining and different degrees of communication with the joint.

We have read the article by Pérez-Santiago L et al. on the conservative or surgical management of pneumatosis intestinalis (PI). Recently we saw a case of a 18-year-old female diagnosed with anorexia nervosa who presented due to general malaise, asthenia, and inability to walk following an episode of abdominal pain, vomiting and diarrhea (10-15 stools daily, some of them bloody). Physical examination revealed signs of malnutrition and dehydration, and a distended, tender abdomen with no signs of peritoneal irritation. Laboratory chemistry tests revealed macrocytic anemia and metabolic alkalosis. An abdominal CT scan showed pancolonic pneumatosis, with greater involvement of the cecum, ascending and transverse colon, as well as pneumoperitoneum and gas in branches of the superior mesenteric and portal veins.
